Description

The battery of the screen of cell panel and manufacture method thereof and this screen of use
The application is to be on June 21st, 2002 applying date, and application number is 02141803.9, and denomination of invention is divided an application for the application for a patent for invention of " battery of the screen of cell panel and manufacture method thereof and this screen of use ".
Technical field
The present invention relates to a kind of screen of cell panel and the battery of manufacture method and this screen of use thereof, described cell panel screen adopts rotary underreamer to make.
Background technology
The cell panel of lead accumulator generally is to make by a kind of active material being inserted the screen mesh of being made by lead or lead alloy.This screen normally directly forms aperture plate by for example die casting lead or lead alloy, perhaps uses reamer alternately to form a plurality of mesh on a metallic plate of being made by lead or lead alloy (the following sheet material that will comprise lead or lead alloy or other alloys is referred to as metallic plate).Described reamer is reversible reciprocity formula, by vertically moving of die-cutting rule, or forms stagger mode by the rotating disc knife rotation, begin order from the two ends of institute's machining sheet and form mesh, and described metallic plate is formed the groove that stretches into mesh by from the two ends broadening.As shown in figure 37, on the dise knife 1 that rotary underreamer uses, a large amount of protrusion 1a and recess 1b alternately form with fixed intervals along the circumferencial direction that encloses the pillar side surface of rosette.The curved cutting face of its center dant 1b constitutes periphery, itself constitute dise knife 1 disk enclose the pillar side surface.The local view table that amplifies is illustrated in the periphery when forming sheet material of incision among Figure 37.Each protrusion 1a forms by the shape of the described periphery of dise knife 1 being made towards peripheral post protuberance.The summit of these protrusions is circular, and its shape is towards the front side of direction of rotation (shown in arrow among the figure).
On this dise knife 1, groove 1c is formed on the junction of disc surface and each recess 1b.The width of each groove 1c equals the length (i.e. interval between adjacent rises 1a) of corresponding recess 1b, and its degree of depth approximately is half of thickness (thickness of dise knife 1) of recess 1b, and these grooves laterally are formed on the disc-shaped surface of dise knife 1.The formation of groove 1c should make the opening of recess 1b be formed on the peripheral pillar side surface, and stretches into certain-length towards center of circle direction.Be formed on the arrangement of the groove 1c in each recess 1b, should alternately be formed on two surfaces.
Many such dise knifes 1 are arranged in the shared rotating shaft, and they separate the spacing of the thickness that is substantially equal to dise knife 1 each other, thereby constitute a dise knife roller.As shown in figure 38, each comprises the dise knife of a plurality of vertical arrangements two dise knife rollers, and a stereotype material passes through between the dise knife roller, forms groove 2a.In this case, shown in Figure 39 (A), upper and lower dise knife roller is placed with respect to a plane, and this plane should allow the recess 1b of upper and lower dise knife 1 to have overlapping each other slightly.In addition, the layout of upper and lower dise knife roller should be able to make it along moving axially half pitch, thereby each dise knife 1 of lower wall rotor is positioned between the dise knife 1 of dise knife roller.Rotatable phase should be regulated like this, and when recess 1b was in bottom, groove 1c was formed on certain disc surfaces of dise knife 1; When recess 1b was in topmost, groove 1c was formed on down on another disc surfaces of dise knife 1; And, when the protrusion 1a of last dise knife 1 be in shown in Figure 39 (B) bottom the time, the protrusion 1a of following dise knife 1 arrives topmost.
As shown in figure 38, when a metallic plate between described dise knife roller, roll out-of-date, the effect of protrusion 1a by upper and lower dise knife 1, on metallic plate 2, form groove 2a, little metal silk 2b between groove 2a is along the adjacent formation of Width of metallic plate 2, and they alternately are molded into the shape of projection vertically by upper and lower protrusion 1a.Shown in Figure 39 (A), in the recess 1b of the upper and lower dise knife 1 that groove 1c constitutes mutually face-to-face, metallic plate 2 is cut, so constantly form groove 2a, and, in groove 1c these recesses that face is arranged in the same way mutually, metallic plate 2 is not cut, and forms node 2c so groove 2a is interrupted.Therefore, on metallic plate 2, the length of each groove 2a should have two projecting shape mutually, that is to say, in being interrupted the process that forms node 2, by forming two protuberances continuously along transmission direction mold pressing protrusion 1a, when node 2c staggered half pitch mutually, the protuberance of adjacent slot 2a formed in a similar manner continuously.Therefore, the shape of groove 2a is the stagger mode shown in the plane graph in the circle among Figure 38.
The formation of many groove 2a on the metallic plate (stereotype) 2 is broadened and form towards both sides along Width through series of steps as mentioned above.As a result, as shown in figure 40, the broadened formation mesh of groove 2a, so form many latticed grids, wherein node 2c interconnects four oblique wire 2b that stretch out.
As shown in figure 47, the dise knife 4 of end is arranged in two axial end portions of lower wall rotor, shown in Figure 48 and 49, alternately forms protrusion 4a and recess 4b on the outer peripheral edges of each in the dise knife 4 of end.The recess 1b of the dise knife 1 that the constituted mode of recess 4b and the groove 4c that forms in recess 4b is complete and common is identical with the constituted mode of groove 1c.But on each protrusion 4a, its outer circumferential side surface is the standard round side face basically, that is to say, the protrusion 4a of the dise knife 4 of end outstandingly forms the protuberance of periphery outward, and recess 4b does not have the intermeshing shape with protrusion 4a yet.The dise knife 4 of end is placed on two ends of lower wall rotor, so can be outwards and the common dise knife of locating in the end of last dise knife roller 1 layout that is overlapping respectively.
Shown in Figure 47 (b), place, end at the dise knife roller, the protrusion 4a of the end dise knife 4 of lower wall rotor is stacked mutually with the protrusion 1a of the end dise knife 1 of last dise knife roller, so the metallic plate 2 between these protrusions is cut, form described groove 2a and stretch out wire 2b down as crowned, shown in Figure 47 (a) and 47 (c), at adjacent part (high order end among the low order end among Figure 47 (a) and Figure 47 (b)), the groove 1c of the recess 1b of the end dise knife 1 of the groove 4c of the recess 4b of the end dise knife 4 of lower wall rotor and last dise knife roller arranges mutually face-to-face, recess 1b and 4b are slightly overlapping each other, therefore metallic plate 2 is cut, and forms groove 2a continuously.; at adjacent part (low order end among the high order end among Figure 47 (a) and Figure 47 (b)); the groove 1c of the recess 1b of the groove 4c of the recess 4b of the end dise knife 4 of lower wall rotor and the end dise knife 1 of last dise knife roller forms on opposite surfaces; so face mutually; groove 1c and 4c make recess 1b and the 4b can not be overlapped, and metallic plate 2 is not cut.Therefore, the node 2f at place, end forms, and it is similar to aforesaid node 2c.Owing to there is groove to form, the node 2f of end is directly connected on the frame part 2g that forms on the end of metallic plate 2 Widths at the place, outer end.
Use metallic plate 2 that reamer will have many groove 2a through series of steps as mentioned above along its Width towards the both sides broadening, the result, as shown in figure 50, groove 2a is broadened, form mesh, so the node 2f of the node 2c of formed many latticed grids and end links together by four oblique wire 2b that stretch out each other.In fact, when wire is added man-hour by oblique towards the direction of turning round, node 2c is stretched.Yet in Figure 50, this turning round is left in the basket, and formed grid as shown in the figure.
The problem to be solved in the present invention (1)
In the screen of aforesaid routine, when forming groove 2a on metallic plate 2, the wire 2b that is connected on each node 2c is bent towards the bottom by protrusion 1a mold pressing.Groove 2a is being processed in the latticed process, and the power on the wire 2b of being applied to concentrates on wire and the bottom that node 2c is connected.If stress concentrates on the bottom of node 2c, the overload phenomenon will take place on the bottom in the course of processing, and might cause the destruction of bottom.Therefore, the corrosion of electrolyte is probably from described bottom, and this can cause the corrosion fracture of wire 2b at battery between the operating period.
The screen that conventional employing reamer is made also has a defective, in being connected of place, bottom wire and a node, ruptures easily owing to corrode, and this makes the lost of life of battery.
The problem to be solved in the present invention (2)
In the conventional dise knife 1 with aforesaid structure as shown in figure 41, each protrusion 1a is not the protrusion that forms isosceles triangle, but scalene triangle, its summit 1i is offset towards rotation direction.Rotating disc knife 1 forms groove 2a on metallic plate 2, and utilizes protrusion 1a to become projecting shape in the fence shape part drawing-die between the groove 2a, thereby makes wire 2b.In this case, protrusion 1a has the isosceles triangle shape, and by the stretching gradually of protrusion 1a, the first half of the fence shape part between groove 2a protrudes projecting shape, on the contrary, latter half only depends on the back bevel drawing-die of the summit protrusion 1a afterwards that is positioned at protrusion 1a.Each wire 2b between groove 2a protrudes protrusion, and first half extends more some morely, thereby attenuates.Form grid by these wires of drawing-die, might make the wall of formed mesh inhomogeneous on thickness.On the contrary, if the summit 1i of each protrusion 1a is offset to the front side, then the fence shape between groove 2a part is by drawing-die at first, and the almost whole front surface on this inclined-plane forms an acute angle theta 10Thereby, so that the time of morning forms the wire that stretches out.Along with rotation, also swell gradually the rear surface, the result, and the even wire drawing of whole wire, and also thickness is consistent.Thus, rotary underreamer uses the summit 1i of the protrusion 1a of dise knife 1 to form along the technical process (referring to SHO59-35694 Japanese patent specification (KOKOKU)) of direction of rotation to the first half skew.
The formation of many groove 2a on the metallic plate 2 is broadened and form towards both sides along Width through series of steps as mentioned above.As a result, the broadened formation diamond-shaped meshes of groove 2a is so make the screen of a cell panel.
The inclined-plane of the 1i both sides, summit of the protrusion 1a that each is connected with recess 1b has angle, leading angle θ 10Than back angle theta 20Steeper, as shown in figure 42, each wire 2b forms projecting shape between the groove 2a of metallic plate 2, therefore, and leading angle θ 11Than back angle theta 21Steeper.When metallic plate 2 by drawing-die, when thereby broadening groove 2a forms mesh, the degree of incision node 2c is bigger, wire between groove 2a is reduced than the intensity of the front end of macrobending, the result, as shown in figure 43, the length of node 2c is reduced, perhaps rupture, the situation of bending is not shown among Figure 43, only illustrate grid in edge's (edge is D among Figure 43).
Make the grid of cell panel if adopt the dise knife 1 of conventional rotary underreamer, especially when the situation of grid as positive pole, the node 2c of mesh and marginal portion D is corroded by electrolyte, the easy hidden danger that fracture takes place or cause corrosion and damage, problem is that the capacity of lead accumulator will reduce, and perhaps its life-span will shorten.
The problem to be solved in the present invention (3)
As shown in figure 44, the projecting shape that is had strain by the wire 2b of the protrusion 1a wire drawing of dise knife 1 formation, the bending curvature of its summit 2e is steeper, if in the course of processing with protrusion towards non-vertical direction wire drawing, become straight line, then the summit 2e of each protrusion keeps strain, therefore can not wire drawing become straight line completely.During wire 2b was by Wire Drawing, tensile stress was easy to concentrate on the both sides of strain of crooked summit 2e.
In fact, wire 2b is not only become straight line by oblique wire drawing during by Wire Drawing, and in its end shown in arrow D and E among Figure 45 towards oppositely being twisted.Shown in Figure 39 (a) or 47 (a) and 47 (c), at each node 2c place, the Width side of metallic plate 2 by the recess 1b of upper and lower dise knife 1 towards oppositely vertically mold pressing, therefore, one roughly is formed between the side and opposite side of its Width corresponding to the level error of the thickness of metallic plate, and the position that is stretched of wire 2b is not in one plane yet.As shown in figure 45, at a node 2c place that is connected to certain end wiry, see that along the Width of metallic plate a side is higher than the plane of metallic plate, and opposite side is lower than the plane of metallic plate.In contrast, at a node 2c place that is connected to the same other end wiry, see that along the Width of metallic plate a side is lower than the plane of metallic plate, and opposite side is higher than the plane of metallic plate.When metallic plate by along the Width stretch process, wire 2b is not on the same plane, node 2c is stretched to both sides along the Width of metallic plate, so form node 2c as shown in figure 45, be that the upper right corner of Figure 45 and the node 2c in the lower left corner are twisted to arrow F direction, in contrast, the node 2c in the upper left corner of Figure 45 and the lower right corner is reversed or twists to the arrow G direction.Wire 2b is between the upper right and upper left node 2c, when 2c is stretched, two end is by respectively towards the direction distortion shown in arrow D oppositely or in the figure and the E, the result, each wire 2b is stretched, two end is reversed distortion simultaneously, thereby consequent distortion power is easy to focus on the strain position, both sides partly of top 2e.
On each wire 2b, when it was stretched, tensile stress and distortion power focused on the strain position, both sides partly of top 2e, and top 2e keeps case of bending, forms one and is compressed part.Therefore, the grid that adopts traditional rotary underreamer to make has a problem, on above-mentioned position, often rupture exactly, in this case, the thickness of metallic plate 2 is greater than 1.0mm, perhaps the rib 1a of dise knife 1 adopts bigger extended portion, and particularly, phenomenon of rupture often occurs near the top 2e of each metal wire 2b.If use the grid make like this to make the cell panel of battery, local corrosion can take place at fracture location, in the worst case, the metal wire disconnection that is corroded causes the lost of life of entire cell.Purpose of the present invention is just in order to propose solution at the problems referred to above, the purpose of this invention is to provide the screen that a kind of cell panel is used, on the outer circumferential sides surface of each rib of dise knife, form the inclined-plane for this reason, and be twisted into metal wire carinate in advance, thereby metal wire is difficult to by deflection, and the present invention also provides the method for making this screen.
The problem to be solved in the present invention (4)
The shape of dise knife 1 and as the manufacturing step of the screen of cell panel shown in Figure 37-40, the dise knife shown in it is the dise knife that rotary underreamer uses.When this cell panel of processing is used screen, on metallic plate 2, form groove 2a and node 2c.Shown in Figure 46 (a), when the crest line 1k of the cutting tip of each node being pressed to dise knife 1, cut, so form the lip-deep groove 1c of outer circumferential sides of recess 1b.Shown in Figure 46 (b), pressure concentrates on facing on the position of being pressed crest line 1k, and fracture occurs in node 2c place sometimes.If this fracture in case take place, because the appearance of fracture causes this place to be corroded, corrosion finally may take place disconnect, thereby produce a problem: the capacity of lead accumulator descends or makes the lost of life of storage battery.
Purpose of the present invention is just in order to propose solution at the problems referred to above, the purpose of this invention is to provide a kind of method of making the screen that cell panel uses, wherein the pressure concentration phenomenon is eliminated, and is difficult to make metal wire 2c by deflection, and the present invention also provides the battery that uses this screen.
The problem to be solved in the present invention (5)
Shown in Figure 47 (a) and 47 (c), when the node 2f of node 2c that forms metallic plate 2 and end, along the side surface of its Width by the recess 1b of upper and lower dise knife 1 and vertically oppositely mold pressing of 4b, and therefore vertical distortion, takes place along the side surface of Width in groove 1c positioned opposite in the dise knife 4 of end mutually, the degree of this distortion is bigger, be equivalent to the thickness of metallic plate 2 or more, the metallic plate 2 with end node 2f is stretched thinlyyer, is beneficial to deform.When metallic plate 2 was stretched two side surfaces to its Width, distortion produced, and metal wire 2b pulls out from node 2c, and end node 2f is because linear deformation and attenuation, and laterally was pressed to oblique case of bending.Therefore, stress concentrates on node 2c and the final leaf 2f, causes may occurring in manufacturing step carries out fracture, and after the battery that uses this cell panel screen is made into, because corrosion or overheated, the possibility that the corrosion disconnection takes place between node and metal wire 2b increases.When one of being meant among the final leaf 2f of the frame part 2g that is connected to metallic plate 2, metal wire 2b that corrosion disconnects locates, this place forms one and is used for from the bead of the screen of cell panel collected current, and described plate portion at the Width opposite side is connected on the described bead by a bending.As a result, make electric current be difficult to flow through, its shortcoming is that the active material in this part can not effectively be utilized, and flows through described crooked position when big electric current, can produce a large amount of heat.If that corrosion disconnects is any one node 2c, rather than final leaf 2f, so also be similarly, electric current is difficult to distribute from the sheet metal part of the opposite side of described Width corresponding to node 2c.Yet because that node 2c and the frame part 2g that forms bead are separated by is very far away, above-mentioned influence is reduced greatly.
Summary of the invention
Purpose of the present invention is just in order to propose solution at the problems referred to above, task of the present invention provides the screen that a kind of cell panel is used, on the outer circumferential sides surface of the recess 1b between the rib 1a of dise knife 1, by adopting the measure of various unanimities, prevent from during being processed into this screen, to rupture, prevent to take place corrosion and corrosion disconnection during the edge of the node of being processed into described screen and grid, thereby ensured that the lead accumulator capacity can not descend, the life-span of battery can not shorten.The invention still further relates to the method for making this screen and the battery that uses this screen.
Be connected to final leaf 2f on the frame part 2g of metallic plate 2 on, metal wire 2b also takes place similarly to corrode the disconnection phenomenon with other nodes 2c easily.In addition, having increasing problem in many batteries is owing to taking place to disconnect on final leaf 2f battery capacity obviously to be descended.Purpose of the present invention is just in order to propose solution at the problems referred to above, task of the present invention provides the screen that a kind of cell panel is used, at the lip-deep recess of outer circumferential sides of the recess of the dise knife 1 of terminal towards the center, thereby reduce the deformation extent of final leaf, make metal wire be difficult to disconnect.The present invention also provides the method for making screen.

Method according to sixth aspect present invention, in the dise knife of rotary underreamer, between the inclined-plane of each recess and each protuberance, all insert a little inclined-plane, by this little inclined-plane, the part bending between the inclined-plane with recess and protuberance in two steps, and the angle of bending is little.When slit forms on metallic plate, the raised portion of the fence shape part between slit is handled by the protuberance mold pressing of dise knife 1, from the bending of the outstanding formation of node ridged, has an acute angle, and can realize required bending in two steps by little inclined-plane, thus, the generation of the edge that has prevented the mesh that forms in each slit process in the processing phenomenon of being corroded by electrolyte easily.
Method according to the screen of the manufacturing cell panel that seventh aspect present invention provided, wherein on metallic plate, form a plurality of slits by the dise knife that adopts rotary underreamer, in slit, be formed on the curvulate part between a node and the fence shape part, a plurality of protuberances on the top of each dise knife move towards the projection of the front side of direction of rotation, between the front portion of the excircle of disc annular surface, form a gap with the interval that equates, outer circumferential sides surface between two protuberances of the formation of the curved surface between the recess, and one is connected the outer circumferential sides surface with described recess at least one front bevel on the outer circumferential sides surface of the protuberance of rear portion adjacency, described curved surface has the contact-making surface at an angle of inclination, it is between the angle of two faces, a plurality of grooves are formed on the outer circumferential edges on two disc surfaces with the angular spacing that equates, these grooves are positioned on each clearance plane, and alternately two face upper sheds.
According to the method for seventh aspect present invention, in the dise knife of rotary underreamer, between the inclined-plane of each recess and each protuberance, all insert a curved surface, by this curved surface, in two steps the part between recess and the protuberance inclined-plane is done bending slightly.When slit forms on metallic plate, the raised portion of the fence shape part between slit is handled by the protuberance mold pressing of dise knife 1, outstanding from a ridged node, it is not the formation angular distortion, and can broad warp, for example realize, thus with fillet technology, form the edge of mesh by the processing slit, the generation of the phenomenon that the edge that has prevented the mesh that forms in each slit process of processing is corroded by electrolyte easily.In explanation during manufacture method of the present invention, particularly the edge that is formed by the little inclined-plane of the protuberance of recess and its latter half of adjacency at least can be with acute angle by broad warp.Therefore, can prevent in node the disconnection problem that corrosion takes place and cause effectively by corrosion.
Method according to the screen of the manufacturing cell panel that eighth aspect present invention provided, wherein on metallic plate, form a plurality of slits by the dise knife that adopts rotary underreamer, in slit, form the node of inclination, a plurality of protuberances on the top of each dise knife move towards the projection of the front side of direction of rotation, between the front portion of the excircle of disc annular surface, form a gap with the interval that equates, a recess is formed in two outer circumferential sides surfaces between the protuberance, described recess forms such surface, its inclined degree towards the center compares the inclined degree height towards the contact-making surface that contacts with annular surface, the contact-making surface that in the described annular surface all contact with described recess, has the identical position of measuring with an axis of rotation, angle, a plurality of grooves are formed on the outer circumferential edges on two disc surfaces with the angular spacing that equates, these grooves are positioned on each clearance plane, and alternately two face upper sheds.
Method according to eighth aspect present invention, because the inclined degree of the recess between the protuberance of the dise knife that uses in rotary underreamer towards the center compares the inclined degree towards direction of rotation, so between the relatively gentle slope of the protuberance of recess and latter half of adjacency, form angle of bend, and the angle of bending is little.And between the gentle slope of the protuberance of recess and front adjacency, form angle of bend, and the angle of bending is precipitous.By adjacent both sides poor between the angle that forms of recess between the inclined-plane of protuberance and protuberance respectively, so can be lowered.When slit forms on metallic plate, node tilts, so the rear side surface of the part of the fence shape between slit only can not take place by the phenomenon that acute angle is bent, the result, make the angle of bend of rear side and front side consistent, thus, the generation of the edge that has prevented the mesh that in the course of processing, the forms phenomenon of being corroded by electrolyte easily.If described recess adopts the formed surface of annular surface that tilts to constitute, the angle that is formed by the contact-making surface of annular surface can be a constant value forever.In addition, described recess also can have a plane inclined or other curved surfaces.
Method according to the screen of the manufacturing cell panel that ninth aspect present invention provided, wherein cell panel is made by a rotary underreamer, use dise knife on metallic plate, to form a plurality of slits, wherein a plurality of protuberances on the top of each dise knife move towards the projection of the front side of direction of rotation, between the outer circumference surface of disc annular surface, form a gap with the interval that equates, and a plurality of grooves are formed on the outer circumferential edges on two disc surfaces with the angular spacing that equates, these grooves are formed on each and constitute in the lip-deep recess of outer circumferential sides between the protuberance, and alternately two face upper sheds.Wherein:
The recess of each dise knife forms such surface, its inclined degree towards the center compares the inclined degree height towards the contact-making surface that contacts with annular surface, in the described annular surface all and the contact-making surface that described recess contacts have the identical position of measuring with an axis of rotation of described dise knife, angle.
Method according to ninth aspect present invention, because the inclined degree of the recess between the protuberance in dise knife towards the center compares the inclined degree height towards direction of rotation, so between the relatively gentle slope of the protuberance of recess and latter half of adjacency, form angle of bend, and the angle of bending is little.And between the gentle slope of the protuberance of recess and front adjacency, form angle of bend, and the angle of bending is precipitous.By adjacent both sides poor between the angle that forms of recess between the inclined-plane of protuberance and protuberance respectively, so can be lowered.So the rear side surface of the part of the fence shape between the slit of metallic plate only can not take place by the phenomenon that acute angle is bent, the result, make the angle of bend of rear side and front side consistent, thus, the generation of the phenomenon that the edge that has prevented the mesh that forms in the course of processing is corroded by electrolyte easily.If described recess adopts the formed surface of annular surface that tilts to constitute, the angle that is formed by the contact-making surface of annular surface can be a constant value forever.In addition, described recess also can have a plane inclined or other curved surfaces.
The present invention is as described in the tenth aspect, it is characterized in that, described recess forms such surface, it towards the inclined degree at center than high 1 ° or more towards the inclined degree of the contact-making surface that contacts with annular surface, in the described annular surface all and the contact-making surface that described recess contacts have the identical position of measuring with an axis of rotation of described dise knife, angle.
According to the scheme of tenth aspect present invention, because the recess between the protuberance in dise knife has 1 ° or more slope, so the angle of the angle of bend bending that forms between the relatively gentle slope of the protuberance of recess and rear portion adjacency can be little certainly.
The present invention as the tenth on the one hand as described in, it is characterized in that, the described recess of a fore-end that comprises only has a surface to form such surface, its inclined degree towards the center compares the inclined degree height towards the contact-making surface that contacts with annular surface, in the described annular surface all and the contact-making surface that described recess contacts have the identical position of measuring with an axis of rotation of described dise knife, angle.
Described recess forms between the protuberance of dise knife, for example, on the formed surface of the annular surface of an inclination, comprise a plane inclined, if this plane inclined has a less angle of inclination, then the described plane adjacent with the protuberance of front and near, the contact-making surface of annular surface wants high towards the inclined degree at center, and more deflection is anterior.In some cases, the part that the protuberance of described recess and front is adjacent can be round, perhaps can insert a little inclined-plane that has the intermediate, inclined angle between described recess and described front end protuberance.The contact-making surface on radiused surface or little inclined-plane can be more outward-dipping than the contact-making surface of the annular surface with same angular positions.But the tenth on the one hand the scheme according to the present invention comprises that the contact-making surface of the described recess between the protuberance of dise knife of fore-end is higher towards the inclined degree at center, and more deflection is anterior.Therefore, we can say at least that the angle of the angle of bend bending that forms can be little certainly between the relatively gentle slope of the protuberance of recess and rear portion adjacency.In some cases, the part that the protuberance of described recess and front is adjacent can be round, perhaps can insert a little inclined-plane that has the intermediate, inclined angle between described recess and described front end protuberance.The contact-making surface on radiused surface or little inclined-plane can be more outward-dipping than the contact-making surface of the annular surface with same angular positions.
The present invention is characterized in that as described in the 12 aspect described annular surface is as the Tilt Datum Plane face of described recess, and it is a plane, is connected the cross spider on described annular surface and the inclined-plane on both side surface.
Conventional recess is meant a lip-deep plane of extending along an annular surface sometimes.On this plane, its latter half of surface is slightly towards centroclinal, its inclined degree is greater than the contact-making surface of the annular surface with same angular positions, more deflection is anterior, but its first half surface slightly towards centroclinal, its inclined degree is greater than the contact-making surface of the annular surface with same angular positions, more be partial to the rear portion, so, can make the angle that forms between the little inclined-plane by recess and protuberance little like this, only be a low-angle.If but recess is to be formed by a plane, and recess is a surface of extending along annular surface, and such scheme has some differences when forming.Therefore in contrast, according to a twelfth aspect of the invention, the recess between protuberance more tilts than the plane, and the angle of bend that is formed by the relatively gentle slope of the protrusion of recess and rear portion adjacency at least can guarantee it is little.

The method of the screen of the manufacturing cell panel that the 13 aspect is provided according to the present invention, wherein rotary underreamer is used for being admitted at one and forms many staggered slits on the metallic plate of processing between two or more dise knife rollers staggered relatively, each dise knife roller is equipped with many dise knifes on same axle, between the dise knife roller, form a gap, the structure of each dise knife is: the outer circumferential sides surface forms carinate towards the excircle projection as the annular surface with predetermined radii of benchmark, alternately form protrusion, and the structure of recess is: its outer circumferential sides surface is along a surface that centers on the benchmark annular surface basically, on the whole excircle of disk outer circumferential edges, on the axle that is centered close to disk of described annular surface; And, each recess forms the groove of an opening towards recess outer circumferential sides surface at the outer circumferential edges place of a disc surfaces, recess adjoins each other by the protrusion that forms with reverse manner, in each dise knife, have inclined-plane one by one outside on the circumferential side surface, the top that it forms from the both sides of each recess extends to described recess, this inclined-plane when its during near the disc surfaces of the groove of formation recess, more tend to axis.
Scheme according to tenth aspect present invention, because the inclined-plane is formed on the outer circumferential sides surface of protrusion of dise knife, the fine rule that constitutes between adjacent slit is carinate, and when the described protrusion of mold pressing formed slit on metallic plate, described fine rule was in pre-distorted shape attitude along the inclined-plane.And these fine rules tilt to described groove.Therefore, in the course of processing, node is pulled to the direction opposite with direction of twist by fine rule, the result, and near the distortion power in summit that concentrates on metal wire during the processing can be reduced.
Described inclined-plane when its during near the disc surfaces of the groove that forms recess more the implication of convergence axis be meant: the contact-making surface on this inclined-plane is to tilt like this, the axis of the described dise knife of convergence more when its separation disc face is nearer, refer to that perhaps this inclined-plane can have such part, the contact-making surface that is it is parallel to described axis, but do not allow to have such part, promptly a contact-making surface stretches to outer circumferential sides sideling.
Such inclined-plane preferably stretches to recess and forms since the outer circumferential sides surface of a protrusion, its position extends to a summit of protrusion along radially being higher than of dise knife described recess three/one or more from recess.Usually, distortion power concentrates near the summit of a metal wire.Therefore, be preferably formed as the inclined-plane of the protrusion of dise knife, make its can extend to as much as possible described summit near.After the inclined-plane formed, it extended from three of the protrusion that is higher than recess/one or more plane, so, be pre-formed effect and effect that the distortion power on metal wire can be determined.
The inclination angle on this inclined-plane is equal to or less than 40 ° corresponding to the benchmark annular surface, if the inclination angle on inclined-plane is 40 °, the edge angle between this inclined-plane and disc face can be set in 60 ° or more, therefore can guarantee the cutting effect of metallic plate.
The screen that cell panel is according to a fourteenth aspect of the invention used is characterized in that, this screen is to adopt as the described manufacture method in the 13 aspect to make.
The scheme of the 14 aspect according to the present invention, owing to can reduce near the problem of the distortion power undue concentration summit of metal wire during processing, therefore fracture may take place or destroy in the screen of cell panel of the present invention hardly.

The method of the tenth eight aspect according to the present invention, a kind of method of making the screen of cell panel is provided, metallic plate is sent into two or more dise knife rollers staggered relatively, adopt rotary underreamer on metallic plate, to form a large amount of staggered slits, each dise knife roller is made up of a plurality of dise knifes that are installed on the same axle, has the slit between them, the structure of each dise knife is: alternately form protrusion, its outer circumferential sides surface is carinate from the outstanding formation of the outside circumferencial direction of benchmark annular surface with predetermined radii, a plurality of recesses, its outer circumferential sides surface roughly extends to form along the benchmark annular surface, on an outer peripheral whole excircle of cutting disc, the center of benchmark annular surface is the rotating shaft of cutting disc; Each recess has the lip-deep groove of outer circumferential sides that an opening is positioned at recess, the recess that adjoins each other on the outer circumferential edges part on a surface of cutting disc, constituted by the protrusion that forms with opposite way, in the dise knife roller, a dise knife roller has and is placed on outmost dise knife, then place more outerly with another dise knife roller that this dise knife roller is staggered relatively than above-mentioned outmost dise knife, the outer circumferential sides surface at recessed center to the benchmark annular surface constitutes recess (after this abbreviating " recess that outmost node forms " as), it is corresponding to the recess on the dise knife that passes through metallic plate another dise knife roller staggered relatively, at outmost dise knife (in outmost dise knife, outer circumferential edges corresponding to the recess of another dise knife of same dise knife roller partly is called " recess " respectively) the card of recess on form a groove, be positioned at the groove of the dise knife of another dise knife roller, described card is pointed to the dise knife of outermost end.
At general node place, distortion greater than the thickness of metallic plate can take place, and its reason is, when the outer circumferential sides surface of the recess of the dise knife of the dise knife roller that is positioned at the metallic plate both sides during from the described metallic plate of both sides backing, will be above the cutting plane, the mid point of this plane between the axle of dise knife roller.In contrast, the described scheme of the tenth eight aspect according to the present invention, the outer circumferential sides surface that forms the outermost end node of the recess on the outermost end dise knife is recessed into corresponding to the benchmark annular surface.An even end of the outer circumferential sides of the recess on the card of the dise knife roller staggered relatively surface backing outermost end node by metallic plate, surpass the cutting plane simultaneously, so, the bottom of the outer circumferential sides surface backing outermost end node of the outermost end node of the recess of formation outermost end dise knife, dise knife enters into the cutting plane foremost.Like this, reduced the distortion at node place, end, so can prevent to rupture from the wire of node drawing.
The outer circumferential sides surface of end node that forms recess is recessed to the center of the annular surface with predetermined radii, and its recessed degree is not less than 30%, and is not more than 70% of plate thickness.If forming the recessed degree in outer circumferential sides surface of the end node of recess is 20% of plate thickness, for example, the distortion of outermost end node will be above 80% of plate thickness, and does not have big difference with prior art.If forming the recessed degree in outer circumferential sides surface of the end node of recess is 80% of plate thickness, the distortion of outermost end node can be limited, and will surpass 20% of plate thickness slightly.Metallic plate is conveyed between the dise knife roller rolls, and make dise knife surpass described cutting plane, thereby be not to constitute in the recess of those end dise knifes of end node of recess to form slit, the formation of these slits also with described protrusion (in the situation of end dise knife, the outer circumferential edges of protrusion that corresponds respectively to other dise knifes of same dise knife roller partly is also referred to as " protrusion ") relevant, generally adopt the identical mode that rolls.Therefore, be in above-mentioned part corresponding to 80% working position of plate thickness and form between the end node of recess and finish.On the contrary, if with each recess arrangement on outer circumferential sides surface that forms the end node of recess is about 50% plate thickness, the distortion at then end node and the position between described node and the metallic plate that centered on can have 50% optimum size of about plate thickness.Certainly, so preferably the recess that forms is not less than 30% of plate thickness, and be not more than 70% of plate thickness.
In those recesses of end dise knife, and nonessential formation groove.Be not to constitute in the recess of those end dise knifes of end node of recess, groove is formed on the panel surface of end dise knife, and direction outwardly.Therefore, except by end dise knife and the situation that the part that is placed on relative outer end is shared, there is no need to form these recesses fully.In contrast, the groove that forms on the end node of recess of end dise knife is formed on the panel surface of end dise knife, direction inwardly, and between these grooves, should leave the space that is used to form end node, on metallic plate, also form those recesses of a dise knife relative with end dise knife.So preferably have in the ordinary course of things, the groove of the end node that forms recess.As described in the present invention's the tenth eight aspect, the outer circumferential sides surface that forms the end node of recess is recessed into.So if formed groove is enough big, just can guarantee between the groove of the recess of dise knife staggered relatively and described recess, to have enough spaces, thereby can not produce compulsory distortion at end inter-node, consequently the formation of groove is not always necessary.
Advise that one is formed on end dise knife but not has recess on the end node of recess and/or the lip-deep inclined-plane of each outer circumferential sides of protrusion, when it during near the outside, this inclined-plane more tends to the center of dise knife.Be not to constitute in the recess of those end dise knifes of end node of recess, metallic plate is conveyed between the dise knife roller rolls, and make dise knife surpass described cutting plane, thereby formation slit, the formation of these slits is also relevant with described protrusion, generally adopts the identical mode that rolls.Therefore, in these parts with form the recessed described outer circumferential sides surface of a step that produces between the end node of recess, thereby can form the unevenness of step at the frame part of metallic plate.If each has an inclined-plane on the outer circumferential sides surface of recess of the end node that forms recess and protrusion, the described frame part of metallic plate is bending gently.
The protrusion of each end dise knife is preferably formed as outer circumferential sides surface or side surface of such benchmark annular surface, and it is corresponding to the center of the more close dise knife of described benchmark annular surface.If adopt the constituted mode identical with common dise knife, make the outer circumferential sides surface of protrusion of end dise knife outstanding for carinate, then the edge of the frame part of metallic plate there is no need vertical conveying, otherwise causes distortion easily, because do not form slit in the outside of protrusion.Substantially exceed cutting plane between the dise knife roller owing to roll the carinate outstanding outer circumferential sides surface of each protrusion of the common dise knife of metallic plate, metallic plate can be cut in due form, even comprises that the outer circumferential sides surface with each recess of the end dise knife of plane dise knife positioned opposite surpasses the situation of cutting plane.Therefore, the outer circumferential sides surface of each recess of end dise knife can be formed on the described benchmark annular surface.If the center of the more close dise knife in formed outer circumferential sides surface, close degree are similar to the outer circumferential sides surface of the end node that forms recess, for example, the frame part of metallic plate can avoid producing bigger unevenness.
Method as the screen of the described manufacturing cell panel in the present invention the 19 aspect is characterized in that: inclined-plane is formed on the outer circumferential sides surface of the end node that forms recess, when such inclined-plane is more inside, and the more close center of circle, inclined-plane.
If form on the outer circumferential sides surface of end node of recess and do not form groove, when the outer circumferential sides surface less from the recessed degree of benchmark annular surface, realize in the recessed space that the distortion of then end node only relies in the recess on the dise knife that faces toward when metallic plate is carried, so there is such possibility, if deflection is big, the distortion of then end node is a kind of extreme sudden change.The scheme of the 19 aspect according to the present invention, inclined-plane are formed on the outer circumferential sides surface of the end node that forms recess, and end node is out of shape gently along this inclined-plane.Even be included in the situation that the end inter-node that forms recess has groove, by on described outer circumferential sides surface, forming an inclined-plane, can make the distortion of end node milder.
As the described screen that is used for cell panel in the present invention the 20 aspect, it is characterized in that: described screen is made by the 18 or 19 described manufacture methods.
The scheme of the 20 aspect according to the present invention is used for the screen of cell panel, and wire is pulled out by end node, and they can fracture hardly.

Below, embodiments of the invention will obtain further instruction in conjunction with the accompanying drawings.
Embodiments of the invention (1)
Fig. 1 and 2 represents first example of the first embodiment of the present invention.Fig. 1 is the local amplification stereogram according to first example of first embodiment of the present invention's realization, a node and near situation thereof with the screen of representing in the mode of amplifying, Fig. 2 is the local enlarged diagram of first example of first embodiment that realizes according to the present invention and the dise knife represented in the mode of the amplifying situation of stacked arrangement mutually vertically.Prior art shown in Figure 37-50 parts that have said function in the scheme of giving an example adopt unified reference number mark.
In the present embodiment, adopt, the screen of the cell panel that is used for lead accumulator be described, but also the method for utilizing rotary underreamer metallic plate to be made the screen that cell panel uses is described with the prior art identical mode of scheme of giving an example.
In the situation of embodiment as shown in Figure 2, dise knife 1,1 misphase that faces toward is mutually vertically placed, and a plurality of upper and lower dise knifes 1,1 constitute the dise knife roller respectively.In dise knife 1,1, recess 1b and the length of protrusion 1a on circumferential direction are to equate mutually.Dise knife 1,1 is so placed and rotation, and their phase place is consistent with each other simultaneously, so recess 1b, and 1b is overlapping vertically mutually, need not artificial moving.On the contrary, in the present embodiment, be placed on the super previous phase angle [alpha] of phase place of the dise knife 1 on upper strata, that is to say, in the present embodiment, the position of last dise knife 1 is shifted to front side (among Fig. 2 shown in the arrow) slightly on direction of rotation.For this phase deviation phenomenon is described by force, goes up dise knife among Fig. 2 and be separated from each other with following dise knife 1,1 in the vertical direction.In fact, each dise knife is placed quite compactly, and recess 1b is overlapping slightly mutually.In Fig. 2, the annular surface of dise knife 1,1 is processed to a horizontal plane.
In the prior art, metallic plate 2 is conveyed into dise knife and following dise knife 1, between 1, they are on phase place and non-migration, and slit 2a is by at the last protuberance and the 1a that time swells, part between the 1a and upper recess and lower concave part 1b, the overlay region of the part between the 1b constitutes, the groove 1c on the recess, and the opening surface of 1c is round about, and node 2c is formed by the overlay region between upper recess and lower concave part 1b, and the opening of the groove 1c on these recesses is faced mutually.The length of each node 2c on vertical (direction of advance shown in Fig. 2 arrow) equals each recess 1b length on circumferential direction, promptly equals the width of each groove 1c.
In contrast, in the present embodiment, when metallic plate 2 is conveyed into dise knife 1, in the time of between 1, only by upper and lower groove 1c, the part that 1c overlaps each other forms node 2c, because the opening of groove is skew mutually, the result makes node 2 length in the vertical be smaller than the length of recess 1b and the width of groove 1c.As shown in Figure 1, metallic plate 2 vertically on the rear side of each node 2c, wire 2b (left front among the figure) is pulled out downwards by the protrusion 1a of last dise knife 1 leading on the phase place, it begins to be bent downwardly from the bottom of node 2c immediately, wire 2b (left back among the figure) is upwards pulled out by the protrusion 1a of the following dise knife 1 that lags behind on the phase place, and it is 2 vertically be bent upwards at the top end of a part 2d who stretches out backwards from node 2c along metallic plate.Metallic plate 2 vertically on the front side of each node 2c, wire 2b (right back among the figure) is upwards pulled out by the protrusion 1a of the following dise knife 1 that lags behind on the phase place, it begins to front curve immediately from the bottom of node 2c, wire 2b (right front among the figure) is pulled out downwards by the protrusion 1a of last dise knife 1 leading on the phase place, and it is 2 vertically be bent downwardly at the top end of a part 2d who stretches out forward from node 2c along metallic plate.The extension 2d of shown irregular formation and node 2c are an integral body, they remain flat in the mode identical with node 2c by the recess 1b one of in the dise knife 1, and metallic plate 2 is rolled cutting by the protrusion 1a of another dise knife 1, does not have groove 1c on it.
The result, in the screen of present embodiment, in four wire 2b that are connected on the node 2c, wire (left front and right back among the figure) on two diagonal begins bending immediately from the bottom of node 2c, and diagonal extension mode is identical with the mode of prior art, yet remaining two wires (left rear side and forward right side) are in the top end bending of described extension, described extension refers to from the bottom of node 2c along vertically the stretching out of metallic plate 2, and extends along diagonal.When screen is added man-hour by the Width along metallic plate 2, being applied to these two tensile stresses on the wire 2b that stretches out from node 2c bending by extension 2d is diffused on the whole extension 2d, therefore, even in the course of processing, extension 2d still can remain on basically the original state to these parts that vertically stretch out.What Fig. 1 represented is the state of processing screen afterwards.In fact, after forming slit 2a by dise knife 1,1, the angle of stretching out wiry in screen is mild, and this extension 2d does not have difference before processing and after the processing.And when adding man-hour, tensile stress is concentrated the bottom that is applied to node 2c not with the configuration of the wire 2b of extension 2d about two, therefore big fault or damage might take place.Identical with the processing mode of prior art, at storage battery between the operating period, these wires are corroded by electrolyte easily, in contrast, big fault or damage can not take place in two wires that dispose extension 2d, and hardly can be owing to electrolyte corrodes, the result, wire is owing to the phenomenon that corrosion causes damaging can reduce.
Present embodiment can be implemented very simply by adopting dise knife same as the prior art 1, only needs when the mounting disc rotor, with the phase deviation of upper and lower dise knife.
Fig. 3 and Fig. 4 represent second example of the first embodiment of the present invention.Fig. 3 represents local enlarged diagram, and the dise knife of representing in the mode of amplifying is the situation of stacked arrangement mutually vertically; Fig. 4 represents local amplification stereogram, a node and near the situation thereof of the screen of representing in the mode of amplifying.
Fig. 5 and Fig. 6 represent the 3rd example according to first embodiment of the present invention's realization.Fig. 5 is local enlarged diagram, represents a part, the situation of the mutual stacked arrangement of dise knife of wherein upper and lower phase shift in the mode of amplifying; Fig. 6 represents local amplification stereogram, represents the node of the screen made by the dise knife of phase shift and near situation thereof in the mode of amplifying.All have the parts identical with the first embodiment function shown in Fig. 1 and 2 and adopt unified reference number sign.Adopt among Fig. 2, Fig. 3 and 5 and represent in a like fashion to separate on the mutual vertical direction of upper and lower dise knife, and annular surface is processed to horizontal plane as shown in the figure.Fig. 1, protruding screen with after 6 represent to process in identical in fact mode.
In the same manner as in the first embodiment, the screen of the plate that is used for storage battery of the of the present invention second and the 3rd embodiment is described, also the method for screen is made metallic plate 2 by the upper and lower dise knife 1,1 of rotary underreamer in explanation.As shown in Figure 3, in the present embodiment, the length that faces toward the recess 1b of the dise knife of installing 1,1 mutually on the vertical direction is different.That is to say that in the present embodiment, the length L d along the circumferential direction of recess 1b of dise knife 1 that is positioned at downside is longer than the length L u along the circumferential direction of the recess 1b of the dise knife 1 that is positioned at upside.Thus, the width of the groove 1c of the recess inner opening of dise knife 1 is also longer under each.By reducing the length of protrusion 1a along the circumferential direction, make on the dise knife 1 down the pitch of recess along the circumferential direction equal the pitch of the recess on the dise knife 1.And the phase place of last dise knife and following dise knife 1 is consistent with each other, makes the center overlaid of whole length of the corresponding concave part 1b of the lucky and following dise knife 1 of each recess 1b of dise knife 1.
Add man-hour when metallic plate 2 being conveyed between dise knife and the following dise knife 1, only node 2c forms on screen, and its length equals the short width of the groove 1c of dise knife 1, and this is that the width of 1c is different mutually because of upper and lower groove 1c.As shown in Figure 4, Width along metallic plate 2, on the side of each node 2c, the protrusion 1a that two wires (among the figure one of the front) are had the last dise knife 1 of short recess 1b stretches downwards, these two wires begin to be bent downwardly from the bottom of node 2c immediately, in contrast, the protrusion 1a that two wires (among the figure one of the back) are had the following dise knife 1 of long recess 1b upwards stretches, these two wires are bent upwards at the top end of extension 2d, and described extension is 2 vertically stretch out forward and backward from node 2c along metallic plate.
When screen when the Width of metallic plate 2 to be processed stretches, being applied to described two stretches out by extension 2d and the tensile stress from the wire 2b of node 2c bending is applied on the whole extension 2d, therefore, even after the course of processing, extension 2d still can remain on basically the original state to these parts that vertically stretch out.Because these two wires are bent upwards at the top end of extension 2d, therefore, big fault or damage can not take place in two wires that dispose extension 2d in the processed process, and hardly can be owing to electrolyte corrodes, as a result, wire 2b is owing to the phenomenon that corrosion causes damaging can reduce.
In second example, as mentioned above, the phase place of last dise knife and following dise knife 1,1 is consistent with each other, and but, their phase place can be skew mutually.For example as shown in Figure 5, following dise knife 1 can be leading on phase place, so groove 1c, the rear end of 1c is consistent vertically each other.The result, as shown in Figure 6, the protrusion 1a that two wires (among the figure right back before) are had the following dise knife 1 of long recess 1b upwards stretches, and these two wires are bent upwards at the top end of extension 2d, and described extension is 2 vertically stretch out forward from node 2c along metallic plate.In the course of processing, be applied to and describedly stretch out and tensile stress from the wire 2b of node 2c bending is applied on the whole extension 2d by extension 2d, therefore, for the wire rod of passing among each node 2c, during using storage battery, wire 2b is owing to the phenomenon that the electrolyte corrosion causes damaging can reduce.

Figure 11 and 12 expressions are according to the 6th example of first embodiment of the present invention's realization.Figure 11 is local enlarged diagram, represents a part in the mode of amplifying, and wherein the mutual relatively vertically stacked arrangement of dise knife has the situation of the groove of phase shift; Figure 12 is local amplification stereogram, represents by the node and near the situation thereof that have the screen that the dise knife that moves on to rightabout groove mutually makes in the mode of amplifying.
Figure 13 and Figure 14 represent the 7th example according to first embodiment of the present invention's realization.Figure 13 is local enlarged diagram, represents a part, the situation of the mutual stacked arrangement of dise knife of wherein upper and lower phase shift in the mode of amplifying; Figure 14 is local enlarged diagram, the node of the screen that the dise knife of representing in the mode of amplifying by phase shift is made and near situation thereof.
Adopt unified reference number sign at those the parts shown in Fig. 1 and 6 with identical function.Adopt the identical mode with Fig. 2 etc., the upper and lower dise knifes of Fig. 7,9,11 and 13 expressions are mutual apart arrangement vertically, and annular surface is processed to a horizontal plane as shown in the figure.Adopt the identical mode with Fig. 1 etc., Fig. 8,10,12 and 14 represents processed screen.
Adopt and the identical mode of first to the 3rd example, these examples in conjunction with present embodiment (Fig. 7-14) illustrates the screen as storage battery plants, illustrate that also how the upper and lower dise knife 1,1 of use rotary underreamer make stereotype 2 method of screen.In the 4th example of as shown in Figure 7 present embodiment, the length L w of described recess 1b is shorter than the width Ln of described groove 1c, particularly in Fig. 7, dise knife 1 is used on each groove 1c, the A/F of groove is Ln, and only be positioned on the central area of whole length L w of flat surfaces 1b (Ln＜Lw).In Fig. 7, the phase place of upper and lower dise knife 1,1 is consistent with each other.
When metallic plate 2 was conveyed between the upper and lower dise knife 1,1, the length of node 2c equaled the width Ln of formed groove 1c, and this is because upper and lower groove 1c, and 1c is corresponding to overlapped.The end that is connected to four wire 2b of node 2c is rolled by recess 1b, and groove 1c in recess is an opening not.As shown in Figure 8, these wires are crooked up or down at the top end of an extension 2d, and this extension is 2 vertically stretch out forward and backward from node 2c along stereotype.
When being stretched along the Width of metallic plate 2, screen adds man-hour, be applied to by extension 2d and stretch out and tensile stress from four wire 2b of node bending is diffused on the whole extension 2d, even like this after the course of processing is finished, extension 2d still can remain on basically the original state to these parts that vertically stretch out.Four wire 2b are connected to all bottoms of node 2c, therefore, in the course of processing, big fault or damage can not take place, and hardly can be owing to electrolyte corrodes, as a result, at storage battery between the operating period, these wires 2b is corroded by electrolyte and the phenomenon that causes damaging can reduce significantly.
In the 4th example of present embodiment, the opening of explanation groove 1c is positioned at the situation at the center of recess 1b.In the 5th embodiment, the opening of groove 1c moves on on the end of recess 1b as shown in Figure 9, and in this case, upper and lower groove 1c, 1c are consistent with overlapped, thereby the length of node 2c equals the width Ln of formed groove 1c.As shown in figure 10, side along each node 2c of the Width of metallic plate 2, two wire 2b (among the figure one of the right side) are rolled vertically by the outstanding protrusion 1a in end from the recess 1b of the groove 1c that has opening, wire begins crooked vertically from the bottom of node 2c immediately, and in contrast, two wires (among the figure one of the left side) are rolled vertically from having not the end of the recess 1b of the groove 1c of opening, wire is crooked vertically at the top end of extension 2d, and described extension is 2 vertically stretch out backward from node 2c along metallic plate.In the course of processing, the tensile stress that is applied on these two wire 2b is diffused on the whole extension 2d, and therefore, at storage battery between the operating period, these wires 2b is corroded by electrolyte and the possibility that causes damaging can reduce.
As shown in figure 11, the groove 1c with opening can be respectively formed on the end of relative both sides of the direction that upper and lower dise knife 1 moves forward and backward along dise knife, and these grooves are offset to the place, end of recess 1b, and upper and lower dise knife 1 relatively rotates.Therefore, the situation of dise knife 1 as shown in Figure 9 has difform dise knife and is used as upper and lower dise knife, in contrast, in the situation of Figure 11, has identical shaped dise knife and is used as upper and lower dise knife, so can obtain the impact-share of parts.In this case, upper and lower groove 1c, 1c are skews mutually, and therefore, node 2c only depends on that part of formation of overlapped groove.As shown in figure 12, the recess 1b that four all wire 2b that are connected on the node 2c are had the groove 1c of opening rolls vertically, and has the not groove of opening on the recess 1b, so wire is crooked vertically at the top end of extension 2d, described extension is 2 vertically stretch out forward and backward from node 2c along metallic plate.In the course of processing, the tensile stress that is applied on these wires 2b is diffused on the whole extension 2d, and therefore, at storage battery between the operating period, these wires 2b is corroded by electrolyte and the possibility that causes damaging can reduce significantly.
As shown in figure 13, groove 1c with opening can be respectively formed on the end of relative both sides of the direction that upper and lower dise knife 1 moves forward and backward along dise knife, these grooves are offset to the place, end of recess 1b, and can on phase place, be offset, make upper and lower groove 1c, 1c can be consistent with each other and overlapping, in this case, upper and lower recess 1b, 1b is skew mutually, but upper and lower groove 1c, and 1c can be consistent with each other and overlapping, therefore, the length of node 2c equals the width Ln of formed groove 1c.As shown in figure 14, in four all wire 2b that are connected on the node 2c, two diagonal wire 2b (left back and right front among the figure) are rolled by upper and lower protrusion 1a, so wire begins crooked vertically from the bottom of node immediately, but remaining two wires (left front and right back among the figure) quilt is had after does not roll vertically the end of the recess 1b of the groove of opening, top end at extension 2d is crooked vertically, and described extension is from bottom vertically the stretching out along metallic plate 2 of node 2c.In the course of processing, the tensile stress that is applied on these two wire 2b is diffused on the whole extension 2d, and therefore, at storage battery between the operating period, these wires 2b is corroded by electrolyte and the possibility that causes damaging can reduce.
In first to the 6th example, illustrated and related to upper and lower dise knife 1,1 phase place is offset mutually, upper and lower plane 1b, 1b has different length, or the length of the recess 1b of the dise knife 1 various assembled schemes bigger than the width of groove 1c, as for dise knife 1, any other assembled scheme of 1 also can be considered to use, and for example, one of is connected among the wire 2b of node 2c at least the shape that has by described extension 2d bending, be and lower concave part 1b, 1b can have different length, and, one of among the upper and lower groove 1c or two width can be shorter than the length of recess 1b.In addition, the phase place of upper and lower dise knife 1,1 can be skew mutually.
In first to the 6th example, in order to simplify description, illustrated at upper and lower dise knife 1, make the situation of screen between 1 by the metallic plate 2 that rolls lead or lead alloy, wherein dise knife how in the dise knife roller combination arrangement can select, not only be defined as metallic plate 2 by two situations about rolling facing to the dise knife roller of placing.On the transmission channel of metallic plate 2, the manufacturing of screen can be installed three or more dise knife rollers.
In first to the 6th example, the situation that the metallic plate 2 processed manufacturings of lead or lead alloy is used for the screen of cell panel has been described, the present invention also can use similarly in following situation: use lead or lead alloy metal metallic plate 2 in addition, manufacturing is used for another screen of cell panel through processed.
By foregoing description as can be known, according to the screen that is used for cell panel of the present invention, wire bends on the top of an extension, and this extension stretches out from node in straight basically mode, can solve thus that wire in the prior art is easy to be corroded and the problem damaged.
The production method of cell panel screen in according to the present invention, lead is wherein pulled out part and is pulled out from node in fact straight mode pulling out the terminal crooked of part, and the lead of consequent screen can be prevented from easily corroding.
Embodiments of the invention (2)
Below, the second embodiment of the present invention will be described with reference to the drawings.
Figure 15 to 17 has shown the second embodiment of the present invention.Figure 15 is the part front view that amplifies, the clearance surface that has shown dise knife, Fig. 6 is the positive longitudinal sectional view of part that amplifies, shown that the palisade between the slit partly raises into dome shape in the metallic plate, and Figure 17 is the part front view that amplifies, shown that curved surface replaces little clinoplain, the situation in the both sides of dise knife recess.
In the similar mode of prior art example that Figure 37 to 50 shows, embodiments of the invention also relate to the dise knife 1 of rotary underreamer.Dise knife 1 is such cutting tool, wherein a large amount of protrusion 1a projection from the peripheral side of thin dish-type steel plate.Protrusion 1a is with the peripheral side projection of equal angular spacing from dise knife 1.The same way as of the prior art example that shows with Figure 41, form each protrusion 1a, thereby raise into the shape of crowned from circumferential surface A, and the summit 1i (Figure 41) of protrusion 1a is by rounding, connects peripheral side between the inclined-plane glossily thereby pass the summit.In each protrusion 1a, form the summit, side shifting forward on direction of rotation.Described at the prior art example, about the inclined-plane of both sides, summit angle from circumferential surface A projection, thus, anterior angle θ 10Near the right angle, perhaps than relief angle θ 20More precipitous.
The recess 1b that prolongs along the circumferential surface A of dise knife 1 is formed between the protrusion 1a.As shown in figure 15, wherein the circumferential surface A in dise knife axle same diameter is processed as the plane, and thus, the angle that is formed by the front bevel of recess 1b and protrusion 1a is θ 10, wherein protrusion closes on it backward, and the angle that the back bevel of recess 1b and protrusion 1a forms is θ 20, wherein protrusion faces with it backward.In Figure 15, be processed as the plane owing to show circumferential surface A, same recess 1b is shown as circumferential surface A in same level.Separately between the inclined-plane of recess 1b and protrusion 1a, wherein protrusion 1a closes on it little inclined-plane 1e in both sides.Each little inclined-plane 1e is the plane, is connected peripheral side between the inclined-plane of recess 1b and protrusion 1a, and has the inclination angle, and little inclined-plane rises from recess 1b with this inclination angle, and this angle is the protrusion angle (θ of the inclined-plane of protrusion 1a from periphery A 10Or θ 20) half.Thus, with the equal angular of recess 1b angle of elevation, little inclined-plane 1e is also connected on the inclined-plane of protrusion 1a, and the inclined-plane of protrusion 1a is by little inclined-plane 1e, with the two-stage angle of bend from recess 1b projection.
In dise knife 1,, be formed on two dish-type surface neutralizations in a recess 1b to groove 1c similar in the prior art example.In the similar modes of prior art example that Figure 38 and 39 shows, the dise knife 1 of a large amount of such formations is arranged on the rotating shaft, and is separated from one another and form rotor, and two roller dise knifes 1 are arranged vertically.
In the rotary underreamer of second embodiment of the invention, metallic plate 2 passes between the dise knife roller of up and down, forms slit 2a thus in metallic plate 2.In metallic plate 2, as shown in Figure 2, the palisade part between the 2a of slit is pushed down by the protrusion 1a of up and down dise knife 1, thereby raises into the shape of crowned.At this moment, as shown in figure 16, bend to the little sweep 2h of two-stage by little inclined-plane 1e, be formed between node 2c and the palisade part, wherein slit 2c does not here connect, and palisade part (lead 2b) raises into the shape of crowned.Little sweep 2h is two terminal bendings, and angle of bend is angle of bend (θ in the prior art 11Or θ 21) half.
Thus, in the second embodiment of the present invention, the palisade part (lead 2b) between the slit 2a of metallic plate 2 can bend to two-stage by little sweep 2h, and crooked angle is half of existing angle of bend.When metallic plate 2 is stretched, make slit 2a broadening and when forming grid, thus, such phenomenon does not take place, and promptly at the end of palisade part, the cutting angle of slit 2a increases, the length of the node 2c that Figure 43 shows is shortened, perhaps reduce the intensity of node, thereby impel the node fracture.As a result, the edge of grid can prevent from easily to be corroded by electrolyte.
In the second embodiment of the present invention, such situation has been described, wherein each recess 1b is made of the surface of extending along circumferential surface A.Perhaps, except the surface of extending along circumferential surface A, recess 1b can be made of other surface, as the plane.Under the situation that plane that recess 1b extends along circumferential surface A in by present embodiment or other curved surface constitute, the inclination angle on surface is the inclination angle of the contact surface before the part that is connected to little inclined-plane 1e.
In the second embodiment of the present invention, such situation has been described, its medium and small inclined-plane 1e is formed on the both sides of each recess 1b.Perhaps, little inclined-plane 1e can only be formed on each recess 1b and at least between the front bevel of protrusion 1a, wherein protrusion 1a closes on recess backward on direction of rotation, because the inclined-plane of the 1a of afterwale portion is with the more steep angle θ about periphery A 10Projection like this, even the angle of bend on the inclined-plane is divided in the structure of two-stage simply, also can prevent the corrosion fracture of node 2c effectively.In the second embodiment of the present invention, such situation has been described, little inclined-plane 1e has medium inclination angle between the inclined-plane of recess 1b and protrusion 1a.When the inclination angle was arranged on arbitrarily angled between the inclined-plane of recess 1b and protrusion 1a, angle of bend can be done gently.Yet, adopting in the present embodiment under the situation at medium inclination angle, the angle of bend of two ends of little inclined-plane 1e is the mildest.
In the second embodiment of the present invention, such situation has been described, promptly little inclined-plane 1e is between the inclined-plane of recess 1b and protrusion 1a.Perhaps, as shown in figure 17, curved surface 1f can be between the inclined-plane of recess 1b and protrusion 1a.All contact-making surfaces that contact with curved surface 1f must have the inclination angle, and this inclination angle is between the inclination angle on the inclination angle of recess 1b and protrusion 1a inclined-plane.Curved surface 1f is preferably by rounding, thereby when more close recess 1b, the inclination angle of protrusion 1b is more approached at the inclination angle, and when the inclined-plane of more close protrusion 1a, the inclination angle on protrusion 1a inclined-plane is more approached at the inclination angle.When the inclined-plane of such formation 1e was between the inclined-plane of recess 1b and protrusion 1a, the palisade part between the slit 2a of metallic plate 2 can raise into the shape of crowned smoothly from node 2c.Thus, prevent the crack, wherein causes of cracks is to cause intensity to reduce owing to form the bending with angle, and the edge of grid is prevented from easily being corroded by electrolyte.

Embodiments of the invention (3)
The third embodiment of the present invention is described below with reference to the accompanying drawings.
The 3rd embodiment is corresponding to the modification of above-mentioned second embodiment, and also is the preferred example that is used to solve problem (2) method that need be solved discussed above.
Figure 18 and 19 has shown the third embodiment of the present invention.Figure 18 is the front view that part is amplified, and has shown the inclination recess of dise knife, and Figure 19 is the positive longitudinal sectional view that part is amplified, and has shown that in metallic plate the palisade between the slit partly raises into the crowned shape.
In the similar mode of prior art example that Figure 37 shows to Figure 50, the third embodiment of the present invention also relates to the dise knife 1 of rotary underreamer.Dise knife 1 is a cutting tool, and wherein a large amount of protrusion 1a are from the peripheral side projection of thin plate-like metallic plate.Protrusion 1a is with the interval that the equates peripheral side projection from dise knife 1, and is disposed in the constant gap of formation between the protrusion that closes on.As shown in figure 18, wherein the periphery A in dise knife axle same radius is processed into the plane, and each protrusion 1a forms, thereby raises into the shape of crowned from periphery A, and by rounding.In each protrusion 1a, form the summit of crowned shape, side shifting forward on direction of rotation.Described at the prior art example, thus, about the angle of inclined-plane, both sides, summit, with relief angle θ from periphery A projection 20Compare anterior angle θ 10More near the right angle, or more precipitous (after this, for each protrusion 1a, anterior angle θ 10One side is called as " high angle one side ", and relief angle θ 10One side is called as " than low angle one side ").
Recess 1b is formed between the protrusion 1a, wherein front side centroclinal to about the periphery A of dise knife 1.About the cross spider between the inclined-plane of the curved surface of high angle one side and the 1a of afterwale portion, recess 1b is made of the surface, wherein by will placing along the curved surface rotation that periphery A extends, thereby makes the front side to centroclinal, and obtains constituting the surface of recess 1b.Thus, recess 1b is such face, wherein contacts the mutually centroclinal constant angle of all contact-making surfaces of recess, and than centering on the rotating shaft of dise knife 1, and the contact-making surface with equal angular position more forward.At this moment, the inclination angle of recess 1b preferably is set to 1 ° or bigger.Because Figure 18 has shown with Surface Machining to be the circumferential surface A on plane, same recess 1b is shown as the plane, and it is about constant angles of periphery A inclination.When recess 1b tilts by this way, the angle of bend θ between the inclined-plane of recess and protrusion 1a high angle one side 30, greater than angle θ about periphery A 10, or become mild, high angle one skew back of wherein above-mentioned protrusion 1a towards after close on it.Recess and protrusion 1a are than the angle of bend θ between the inclined-plane of low angle one side 40, less than angle θ about circumferential edge A 20, or steepen, wherein protrusion 1a's closes on it towards preceding than low angle one skew back.Yet, about the angle θ of periphery A 10Originally fully more near the right angle, or than angle θ 20More precipitous, like this, about the angle θ of recess 1b 40Angle of approach θ more 30Thereby, reduce difference.
In dise knife 1,, be formed on disk-like surface and in a recess 1b to those the similar groove 1c in the prior art example.In the similar modes of prior art example that Figure 38 and 39 shows, a large amount of dise knifes 1 that constitute like this are arranged on the rotating shaft, and are separated from one another and form rotor, and two roller dise knifes 1 are arranged vertically.At this moment, the similar manner of the prior art example that shows with Figure 39 is placed the up and down rotor of dise knife 1.Yet in this embodiment, recess 1b tilts, and roller is placed on such level separately like this, and the surface portion at close center is slightly overlapping each other promptly to allow recess 1b at least, and does not form the gap betwixt.
In the third embodiment of the invention rotary underreamer, metallic plate 2 passes between up and down roller shape dise knife 1, forms slit 2a thus in metallic plate 2.In metallic plate 2, as shown in figure 19, the palisade between the 2a of slit partly passes the protrusion 1a of up and down roller shape dise knife 1, and raises into the shape of crowned, forms as lead 2b.At this moment, the node 2c that separate in the slit is formed slopely by the recess of dise knife 1.As a result, about the angle of bend θ of the high angle one skew back face of afterwale portion 31By being done gently, and about the angle of bend θ than low angle one skew back face of preceding protrusion 41Done precipitously, thereby the difference between the angle reduce.Palisade part (lead 2b) between the slit 2a that closes on each other, on each comfortable relative direction, just protruding on the direction up and down.Thus, the palisade of node 2c both sides part just tilts on the direction up and down on relative direction separately, and node 2c is originally as twisted state like this.
Thus, in the present embodiment, the palisade part between the slit 2a of metallic plate 2, only at high angle one lateral bending song, crooked angle is precipitous, and higher and than the angle of bend θ of low angle one side 31And θ 41Can be average.Thus, when metallic plate stretches, make the slit broadening and when forming screen, phenomenon of the prior art does not take place, and promptly in the part of the palisade between the 2a of slit, has only the cutting angle of high angle one side big, and length and the intensity of the node 2c that Figure 43 shows reduce, and impel in the marginal portion and rupture.As a result, the edge of screen can prevent from easily to be corroded by electrolyte.
In the present embodiment, described the situation that recess 1b is made of the surface, wherein, obtained constituting the surface of recess 1b by placing along the curved surface rotation that circumferential surface A extends.Recess can be made of the surface of any kind of, as long as all contact surfaces that contact with recess 1b are to centroclinal, than the contact surface that contacts with periphery surface A on the equal angular position more forward.Perhaps, the surface can be curved surface or plane rather than the surface of extending along circumferential surface A.When recess 1b when tilting a low-angle plane, a kind of situation occurs sometimes, promptly have only fore-end to tilt, more forward than the contact surface of the circumferential surface A of equal angular position to outer periphery more.Equally in this case, can access such effect, promptly be done gently about the angle of bend of the high angle one skew back face of the 1a of afterwale portion.In some cases, by rounding, perhaps, the little inclined-plane with medium inclination angle is in this part than the part between the low angle one skew back face for recess 1b and the protrusion 1a that closes on forward.Equally under these circumstances, can not only obtain such effect, promptly do further gently, and obtain such effect, promptly do gently about the angle of bend of the high angle one skew back face of the 1a of afterwale portion about the angle of bend of preceding protrusion 1a than low angle one skew back face.Just, be not included in the preceding end portion of recess 1b at least, the surface that contacts with recess 1b can be centroclinal surface, than the contact surface that contacts with periphery surface A in the equal angular position more forward.
In the present embodiment, described such situation, promptly constituted recess 1b, thus with the surface of recess 1b to centroclinal, the contact surface that contacts with periphery surface A than equal angular position is more forward.Perhaps, the surface that contacts with recess 1b can be made of centroclinal surface, compares with the plane that the cross spider between the inclined-plane of the periphery A of both sides and protrusion 1a is connected together, and above-mentioned surface more forward.In selection,, obtain the surface that certain forward end partly tilts in the scope even recess 1b is the low-angle plane that tilts.
Example 1
The stereotype of being made by lead or lead alloy 2 is used as metallic plate 2, and by using the dise knife 1 in the prior art example to form and processing slit 2a, in the prior art example, recess 1b does not tilt, this situation and second kind of situation compare, under second kind of situation, by using the dise knife 1 of present embodiment, slit 2a is formed in the header board 2, and recess 1b tilts in the present embodiment.Result relatively is presented in the table 2.

In the superincumbent table 2, about higher and than the crack percentage of low angle one side and the life performance of lead accumulator, the inclination angle of its center dant 1b is 0 ° a prior art example, with inclination angle wherein be that the example of 0 °, 1 °, 3 °, 5 °, 8 ° or 10 ° is compared to each other.Particularly, have the rotary underreamer of every type of dise knife 1 by use, lead holds plate 2 and forms screens, and active material injects screen, and screen is formed positive plate by maintenance and dry then.Positive plate is with the negative plate of producing by existing method and mainly constitute separator by microporous polyethylene and be grouped together, and automobile-used lead accumulator steams next life.Lead accumulator is subjected to the underload life tests according to JIS standard (D5301) in 75 ℃ gas phase.After life tests finished, battery was disintegrated, and checked that node 2c in the screen is higher and than the ratio of the crack part of low angle one side.
From the comparative result that table 2 shows, see, in the prior art example, the percentage height in high angle one side crack, on the contrary, in the present example, higher slightly than the percentage in low angle one side crack, and when the inclination angle was bigger, the total percentage in crack was lower.Further see, in view of the above, when the inclination angle is bigger, also improve morely 75 ℃ SAE life performances to have suitable big value up to the inclination angle.
See obviously that from top description according to method of producing cell panel screen of the present invention and the device that makes in this way, when more forward, the recess between the dise knife protrusion is more to centroclinal.As a result, the angle of bend between recess and the protrusion relatively gentle slope that closes on it backward can be done greatly, thereby relaxes.When the slit is formed in the metallic plate, thus, node tilts, and the palisade between the slit partly raises into the precipitous angle of elevation of crowned shape and can do gently, thereby this part can prevent from easily to be corroded by electrolyte, the capacity that prevents battery thus reduces, and prevents the lost of life of battery.
Embodiments of the invention (4)
The fourth embodiment of the present invention is described below with reference to the accompanying drawings.
Figure 20 to 26 has shown the fourth embodiment of the present invention.Figure 20 is a front view, shown whole dise knife, and the periphery edge that has shown dise knife in the amplification mode, Figure 21 is the perspective view that part is amplified, the inclined-plane that has shown the peripheral side formation of protrusion, wherein protrusion pass dise knife recess and relatively, Figure 22 is a part Zoom Side longitudinal sectional view, the slit that has shown rotary underreamer forms step, and the lead distortion of metallic plate has been described, in the dise knife protrusion of up and down portion rotor, form the mode on inclined-plane, Figure 23 is the perspective view that part is amplified, shown metallic plate, and illustrated in the slit and formed the node that forms in the step, and four bar lead is attached thereto, Figure 24 is the perspective view that part is amplified, another first configuration example that has shown the inclined-plane that forms in the protrusion peripheral side, wherein protrusion pass dise knife recess and relatively, Figure 25 is the perspective view that part is amplified, another second configuration example that has shown the inclined-plane that forms in the protrusion peripheral side, wherein protrusion passes the recess of dise knife and relatively, and Figure 26 is the perspective view that part is amplified, another the 3rd configuration example that has shown the inclined-plane that forms in the protrusion peripheral side, wherein protrusion pass dise knife recess and relatively.
In the similar mode of prior art example, the fourth embodiment of the present invention also relates to rotary underreamer, is used to produce the screen of battery (lead accumulator) pole plate.As shown in figure 38, metallic plate 2 passes between the dise knife roller of up and down, and forms a large amount of sawtooth slit 2a in metallic plate 2.Part between the 2a of slit constitutes lead 2b on the Width of stereotype 2, and the part between the slit constitutes node 2c on direction of advance.
In each dise knife roller, in the identical mode of prior art example, arrange a large amount of dise knifes 1, form the slit betwixt.Yet dise knife 1 constitutes in the different mode of prior art example.In dise knife 1, as shown in figure 20, at the periphery edge of metal dish whole circumference, alternately form the recess 1a that has long relatively peripheral length in a large number, with protrusion 1b with relative peripheral length of lacking.In each recess 1b, form peripheral side with the same way as of prior art example, wherein peripheral side is formed by the circle of reference perimeter surface of predetermined diameter, and dise knife 1 spool on centering.At the groove 1c of the peripheral side opening of recess 1b, be formed on the periphery edge part on a dish-type surface, wherein form in just opposite mode by the recess 1b that protrusion 1a closes on each other.In Figure 20, oval zoomed-in view has shown the circle of reference perimeter surface that is processed into plane form equally.
In each protrusion 1a of dise knife 1, peripheral side becomes the shape of crowned from the outside peripheral projection of circle of reference perimeter surface.Shown in the oval zoomed-in view of Figure 20, the peripheral side of protrusion 1a forms the shape of crowned, wherein peripheral side is in fact linear mode, tilt to rise to outside peripheral side from the circle of reference perimeter surface, wherein the circle of reference perimeter surface is the peripheral side of recess 1b, the peripheral side of protrusion 1a is in the bending of the summit of protrusion 1a, and with the landing of tilting of the inside peripheral side of in fact linear mode, thereby turn back to the circle of reference perimeter surface.On the direction of rotation about protrusion 1a summit, the rising of protrusion 1a peripheral side and landing part form unevenly.In fact, summit side shifting forward on direction of rotation, the rising part of direction of rotation front side is a peripheral side, peripheral side is more precipitous than the landing part of rear side.The summit of protrusion 1a structure of side shifting forward on direction of rotation is identical with prior art constructions.
Inclined- plane 1g, 1g are formed in the rising and landing part of protrusion 1a peripheral side separately.As shown in figure 21, from the rising of protrusion 1a peripheral side and the centre of sloping portion, arrive in the scope of recess 1b, each self-forming inclined-plane 1g, and the mode identical with groove 1c forms the surface, and wherein for each recess 1b, the surface alternately tilts in an opposite direction.For each recess 1b, when more close dish-type surface (lower right side in Figure 21), the inclined-plane is centroclinal to dise knife 1 rotating shaft more, wherein, the descending and ascending portions of each comfortable protrusion 1a peripheral side forms at the groove 1c of recess 1b split shed, and wherein sloping portion is in the front side of direction of rotation, and rising part is at the rear side (perhaps passing recess 1b decline respect to one another and rising part) of direction of rotation, and bump closes on the both sides of recess 1b.Thus, at the peripheral side of a suitable protrusion 1a, be formed on the inclined-plane 1g of rising part and be formed on inclined-plane in the sloping portion, each comfortable relative direction tilts.
In the present embodiment, inclined-plane 1g is made of the plane of triangle sealing, and wherein the summit is some A, B and the C that Figure 21 shows.In this case, point A is such point, when middle part from the sloping portion edge of protrusion 1a peripheral side, when the distance on protrusion 1a summit was indicated by H, wherein above-mentioned protrusion 1a showed in the upper right side of Figure 21, points to a side of Figure 21 lower right side on the dish-type surface, promptly as the circle of reference perimeter surface of recess 1b peripheral side, the tangent line of the circumferential surface of the radius big H/2 more predetermined and the peripheral side of protrusion 1a than circle of reference perimeter surface, their intersection dish-type surfaces.Point B is such point, wherein points to a side of upper left side among Figure 21 on the dish-type surface, and the landing part edge of protrusion 1a peripheral side contacts with the peripheral side of recess 1b.Point C is such point, it points on the periphery edge of Figure 21 lower right side on the dish-type surface, and compares more close protrusion 1a along the circle of reference perimeter surface with an O, wherein the landing part of the original peripheral side of protrusion 1a contacts with the original peripheral side of recess 1b at an O.Because it is more close to protrusion 1a to put C, inclined-plane 1g partly tilts about the landing of protrusion 1a peripheral side.
The inclined-plane that is formed on recess 1b upper right side that Figure 21 shows has been described in the above.Equally, the inclined-plane 1g that is formed on recess 1b lower-left side that Figure 21 shows, the plane of being sealed by similar triangles constitutes, and is such plane, and it tilts at the equidirectional about protrusion 1a peripheral side.For another recess 1b that closes on recess 1b by protrusion 1a, wherein another recess 1b does not show in Figure 21, has formed inclined- plane 1g, 1g, and they tilt in relative direction.
When metallic plate 2 uses dise knife 1 to pass between the dise knife roller, wherein form inclined-plane 1g, in the moment that slit 2a is formed by protrusion 1a, metallic plate is by the inclined-plane 1g vertical pressing of dise knife 1 protrusion 1a, as shown in figure 22, and thus, when distortion, lead 2b forms the shape of crowned.Section shape is not a rectangle, but parallelogram.In every lead 2b, as shown in figure 23, form the part of being pushed by the inclined-plane 1g of protrusion 1a, the end portion (dotted portion among Figure 23) that promptly is connected to node 2c forms, and twists from starting point.The direction of twist of lead 2b end portion is by the arrow R of Figure 23 indication, and the direction of node 2c distortion that is connected to end portion in this direction and the course of processing is relative, the direction of promptly having got in touch the arrow F of Figure 45 description.The direction of twist of arrow R and F relation respect to one another also is applied among two top lead 2b of Figure 23 demonstration.In the course of processing, among the node 2c that in Figure 45, twists on the direction of arrow G, form the lead 2b that is connected with node, on the direction relative, twist with arrow G.
According to such structure, when slit 2a is formed in the metallic plate 2, end at every lead divides under the state that is twisted in advance by inclined-plane 1g, and wherein inclined-plane 1g is formed on the peripheral side of dise knife 1 protrusion 1a, and the rotary underreamer of present embodiment is deformed into lead 2b the shape of crowned.And, in the course of processing of metallic plate 2, on the direction relative with the direction of node 2c distortion, the end portion distortion of lead 2b.Even node 2c distortion in the course of processing, wherein in fact metallic plate 2 is processed in the course of processing, and thus, the lead 2c that is connected on the node bears distorting stress, has wherein cancelled the distortion of using in advance.As a result, in lead 2b, the influence that is applied to the distorting stress of end portion can reduce, and can prevent that distorting stress from concentrating near the summit 2e of lead 2b.
In the present embodiment, described such situation, wherein compared the more close protrusion 1a of the some C of inclined-plane 1g along the circle of reference perimeter surface with the some O that Figure 21 shows.Perhaps, as shown in figure 24, some C can be close to the axle that along groove 1c edge is dise knife 1 radial direction.Under the situation of Figure 21, when inclined-plane 1g constitutes as shown in figure 24, the peripheral side broadening of recess 1b is with the area of triangle BOC, and inclined-plane 1g is connected on the peripheral side of recess 1b and groove 1c naturally, thereby the distortion that is applied to lead 2b end portion can be mild.Yet under the situation of Figure 24, by forming peripheral side, wherein do not form the edge of groove 1c one side in the dish-type surface, consistent with the circle of reference perimeter surface, and when the dish-type of more close formation groove 1c is surperficial, radius is done forr a short time, and the peripheral side of recess 1b is impelled the BC side along inclined side 1g to extend.
Perhaps, as shown in figure 25, the some B of inclined-plane 1g can move to the edge of groove 1c opening along the circle of reference perimeter surface among Figure 24.In selection, although the Breadth Maximum of inclined-plane 1g is the only about half of of protrusion 1a peripheral side width, even under the situation that the only about half of part of lead 2b width rather than entire portion are twisted in advance, distorting stress also can reduce.
Because groove 1c is used for preventing that slit 2c is formed on metallic plate, its further groove is used for node 2c is formed on metallic plate 2, and by the gap mode between the groove of groove and relative dise knife 1, groove 1c does not always need to be rectangle.As shown in figure 26, for example can form groove 1c by the peripheral side of recess 1b is cut sth. askew, thereby be made of the surface, wherein the side, edge of the inclined-plane 1g of both sides is connected to each other by this surface.
Replace the peripheral side of relative protrusion 1a in the dise knife 1, push each other, thus, in metallic plate 2, form slit 2a by metallic plate 2.Thus, preferably the peripheral side that is provided with as far as possible exactly by protrusion 1a forms, and with the angle of dish-type surface respective edges of dise knife 1, be generally 90 °.Yet when inclined-plane 1g was formed on the peripheral side of protrusion 1a, inclined-plane 1g and dish-type surface had the obtuse angle inevitably.When angle was big especially, metallic plate 2 can not be cut reliably, and did not form slit 2a.Thus, the inclination angle of inclined-plane 1g must be provided with not too big.Inclination angle about the circle of reference perimeter surface preferably is set to be equal to or less than 40 °, thereby the angle at edge can be set to 60 ° or bigger between inclined-plane and the dish-type surface, allows slit 2a to be formed on definitely in the metallic plate 2 thus.
In order to prevent that distorting stress from concentrating near the summit 2e of lead 2b, be preferably formed as inclined-plane 1g, and from the part on as close as possible protrusion 1a summit.Thus, preferably the some A of the inclined-plane 1g on close summit is arranged on the level of apex height H 1/3rd at least.In the present embodiment, some A is positioned on the only about half of level of apex height H.Certainly form inclined-plane 1g, and from the position on more close summit.Yet when forming inclined-plane 1g, thereby when extending to the position on the most close protrusion 1a summit, the initial moment that forms the cutting of slit 2a in metallic plate 2, inclined-plane 1g support metal plate 2, like this, edge about the dish-type surface has the obtuse angle, causes a kind of possibility thus, and cutting operation can not smoothly be begun.
In the present embodiment, described such situation, wherein inclined-plane 1g forms flat surfaces.Yet the inclined-plane needn't be always smooth, as long as when the more close dish-type of the side surface that the groove 1c of the recess 1b that closes on forms, the surface is more near the axle of dise knife 1, and can form by curved surface or a plurality of plane.Inclined-plane 1g need not be the triangle that is centered on by three summits.
In the present embodiment, described rotary underreamer, wherein metallic plate 2 passes up and down or two dise knife rollers.The dise knife roller can be arranged in any way.It is heavy that the present invention can similarly be applied to rotary underreamer, and wherein metallic plate 2 passes between the three or more dise knife rollers of positioned opposite.
In the present embodiment, described such situation, wherein handled metallic plate 2, and produced screen, screen is used in the cell panel of lead accumulator.The invention is not restricted to lead accumulator, and can be applied to the storage battery of any kind of, as long as similar screen is as the electric current collection parts of cell panel.Can produce screen by the metallic plate that uses suitable material, wherein suitable material is corresponding to the kind of battery.
Example 3
By using the dise knife of having described in the dise knife 1 described in the present embodiment and the prior art example 1, from metallic plate (stereotype) 2, produce the screen of present embodiment and prior art example.After processing, near the summit 2e by concrete observation lead 2b, check the ratio of fracture.Active material injects the screen of present embodiment and prior art example, maintenance and dry then, thus form positive plate.Pole plate is attached in the lead accumulator (the 55D23 type of JIS) that automobile uses, and injects the sulfuric acid of specified rate dilution, and wherein sulfuric acid has predetermined weight, and moulding finishes, thereby finishes battery.Execution detects life performance according to the detection that overcharges of JIS, and checks the crack ratio of lead after detection.In all lead accumulators, use existing pole plate as negative plate, and mainly constitute separator between pole plate by microporous polyethylene.
At the protrusion 1a of the dise knife 1 of present embodiment, inclined-plane 1g constitutes triangle projective planum, as shown in figure 21.Produce screen,,, be 20%, 50% (H/2) or 70% of protrusion 1a apex height H to the height of the inclination starting position (some A) on the inclined-plane on close summit wherein from the circle of reference perimeter surface of recess 1b peripheral side.In principle, inclined-plane 1g is set to 30 ° about the inclination angle of circle of reference perimeter surface.Yet, in the inclination starting position of inclined-plane 1g is set to 70% screen, in 10 ° to 50 ° scope, producing a plurality of screens.
Comparative result between in present embodiment and the prior art example is presented in the table 3, last column at table 3 shows, and the inclination angle of inclined-plane 1g is set in 50 ° the sample, can not produce screen, like this, can not check and detect sample, because the edge between the dish-type surface of inclined-plane 1g and dise knife 1 is too blunt, thereby metallic plate 2 can not be cut, and the slit can not form.See that thus preferably the inclination angle of inclined-plane 1g is set to 40 ° or littler.

Result has as a comparison determined in all examples, and near the crack ratio the 2e of summit is lower than prior art example, and perhaps its ratio is 40%, and aspect the validity that suppresses the fracture generation, all examples are all effective.In all examples, about life performance after detecting and the crack ratio of lead 2b, compare with in the prior art example those, the life-span is longer and the crack ratio is lower, with the crack ratio reduce consistent.In the inclination starting position of inclined-plane 1g is set to 20% sample, difference about the prior art example is relatively little, so see, preferably the inclination starting position is arranged on the height H 1/3rd (about 33%) or higher position on protrusion 1a summit.
Obviously see in the superincumbent description, according to screen that is used for cell panel of the present invention and the device that is used for this screen, the lead of metallic plate is pressed into the shape of crowned by the inclined-plane, and is twisted state, and wherein the inclined-plane is formed in the peripheral side of dise knife protrusion.Thus, near the lead summit, generation and distorting stress are in an opposite direction concentrated and can be suppressed in the course of processing.As a result, in the lead of screen, can prevent corrosion and corrosive shake, take place thereby can suppress battery failures, and the life-span of battery can prolong.

Figure 30 to 36 has shown the sixth embodiment of the present invention.Figure 30 is the positive longitudinal sectional view that part is amplified, shown by last, the dise knife of lower wall rotor forms the process in slit in metallic plate, Figure 31 is an end view, the structure that has shown the least significant end dise knife, Figure 32 is the perspective view that part is amplified, the structure that has shown the least significant end dise knife, Figure 33 is the perspective view that part is amplified, shown least significant end node in the screen near, wherein by processing the slit that in metallic plate, forms, and obtain screen, Figure 34 is the positive longitudinal sectional view that part is amplified, shown by using the least significant end dise knife, in metallic plate, form the process in slit, in the least significant end dise knife, the inclined-plane is formed in the peripheral side of protrusion, Figure 35 is the positive longitudinal sectional view that part is amplified, shown by using the least significant end dise knife, in metallic plate, formed the process in slit, in the least significant end dise knife, the peripheral side of recess constitutes circumferential surface, and Figure 36 is the positive longitudinal sectional view that part is amplified, and has shown by using the least significant end dise knife, forms the process in slit in metallic plate, in the least significant end dise knife, the peripheral side of recess depression.
In the similar mode of prior art example, present embodiment also relates to rotary underreamer, is used to produce the screen of lead accumulator cell panel.In rotary underreamer, as shown in figure 38, metallic plate 2 passes between the dise knife roller of up and down, and forms sawtooth slit 2a in metallic plate 2.Last dise knife roller constitutes with the same way as of prior art example.The lower wall rotor has the structure identical with the prior art example, and wherein least significant end dise knife roller 4 is placed on two ends of a large amount of dise knifes 1, but those of the structure of least significant end dise knife 4 and prior art example are different.
In the identical mode of prior art example, same in each least significant end dise knife 4 of present embodiment, shown in Figure 31 and 32, protrusion 4a and recess 4b arranged alternate are at periphery edge.Yet the protrusion 4a of least significant end dise knife 4 and recess 4b have shown that wherein dise knife 1 is placed in the same disc rotor corresponding to the periphery edge of protrusion 1a in the dise knife 1 and recess 1b, and always do not have the shape of crowned or the shape of concavity.Particularly, constitute, and the peripheral side of centering is formed among the protrusion 4a on the axle of least significant end dise knife 4, and recess 4b does not form the sunk part between the protrusion 4a by the reference circumference side of predetermined radii.Unlike the prior art example, groove 4c is not formed among each recess 4b, intilted surface is to central concave from the circle of reference perimeter surface, and intilted peripheral side, it is formed among each recess 4b (node of least significant end forms recess) of arranged alternate one side, and outward-dipping surperficial 4e is outward-dipping, and it is formed among each recess 4b of opposite side.The peripheral side of one side recess 4b forms intilted surperficial 4d, it is made of the part conical surface, wherein with the (rear surface among Figure 31, outside dish-type surface of least significant end dise knife 4, with the right front surface among Figure 32) part that contacts, consistent with the circumferential surface of centering on the axle of least significant end dise knife 4, and wherein the predetermined radii of radius ratio circle of reference perimeter surface is little, differs 50% of metallic plate 2 thickness.When being moved further, the radius of conical surface is littler to inner surface (the left back surface of the front surface of Figure 31 and Figure 32) from this part.In the recess 4b of a side, form peripheral side, wherein from closing on the protrusion 4a of both sides, peripheral side depression one-level, and peripheral side is made of the circle of reference perimeter surface, and peripheral side is made of intilted surperficial 4d, wherein when the inside of more close least significant end dise knife 4 dish-type surface, intilted surperficial 4d tilts more to the center.Intilted dish-type surface does not always need the part for conical surface, and depends on process environment or similar, can be the plane or the curved surface of any other kind, if surperficial peripheral side depression from protrusion 4a, and slope inwardly.
Each recess 4b of least significant end dise knife 4 opposite sides (the least significant end node forms except the recess), form outward-dipping surperficial 4e, wherein outward-dipping surperficial 4e is made of a part of conical surface, wherein with the surperficial part that contacts of the inside dish-type of least significant end dise knife 4, consistent with the circle of reference perimeter surface of predetermined radii, and when the outside dish-type surface of least significant end dise knife 4 was mobile, radius was less than predetermined radius from this part.Thus, the recess 4b of opposite side has such shape, and promptly outermost diameter equals the diameter of the protrusion 4a that closes on both sides, and forms peripheral side, wherein peripheral side is made of the circle of reference perimeter surface, and outermost inclined-plane cuts by dish-type surface tilt externally and constitutes.Equally, outward-dipping surperficial 4e does not always need the part for conical surface, and depends on the environment of process or similar, can be the plane or the curved surface of other kind, as long as during more close outside dish-type surface, compare with the peripheral side of predetermined diameter, the surface is more to centroclinal.
The least significant end dise knife 4 of Gou Chenging is placed on the end of lower wall rotor separately like this, thereby at the end of last dise knife roller and common dise knife 1 outwards side by side.Adjust the phase place of direction of rotation, thereby recess 4b is relative with the recess 1b of the dise knife 1 of last dise knife roller in upper end by metallic plate 2, its center dant 4b is the least significant end node that forms least significant end dise knife 4 recesses, and groove 1c is formed among the apparent surface.Transport metal plate 2, thus pass between the dise knife roller of up and down.At this moment, go up in the prior art, metallic plate 2 is placed on the transportation surface and transports, and wherein the surface of the cutting between up and down dise knife roller S is consistent with transportation surface.On the contrary, in the present embodiment, transportation surface is provided with to such an extent that be lower than cutting planes S, differs 50% of metallic plate 2 thickness.In the prior art, the cutting planes S of up and down dise knife roller is set, thus with the transportation surface of metallic plate 2, i.e. the lower surface unanimity of metallic plate 2.On the contrary, in the present embodiment, the cutting planes of up and down dise knife roller is set, thereby consistent with the middle part of metallic plate 2 thickness, wherein metallic plate 2 transports on transportation surface.Cutting planes S is such plane, promptly to up and down dise knife roller the axle distance be equal to each other.The circle of reference perimeter surface is formed the peripheral side of the recess of each up and down dise knife 1, and the predetermined diameter of circle of reference perimeter surface is a bit larger tham the distance from axle to cutting planes S.When the peripheral side of last dise knife 1 recess 1b during in lower end, peripheral side is downwards just over cutting planes S, and the peripheral side of following dise knife 1 recess 1b, the peripheral side of least significant end dise knife 4 protrusion 4a, with except the least significant end node that forms recess, the most external week edge tail of the recess 4b peripheral side of least significant end dise knife 4 all a little upwards surpasses cutting planes S.
When metallic plate 2 passes between the dise knife roller of up and down, when the recess 1b of up and down dise knife 1 overlaps each other in cutting planes S, shown in Figure 30 (a) and 30 (c), in the part in the up and down dise knife 1 that groove 1c faces with each other in the opposite direction, cutting metal plate 2 and form slit 2a, and in the part that groove 1c faces with each other, metallic plate 2 is not cut, and forms node 2c.At the recess 4b of least significant end dise knife 4 is to form under the situation of least significant end node of recess, be the groove 1c (right end among the left distal end among Figure 30 (a) and Figure 30 (c)) that recess is faced the last dise knife 1 that closes on, form least significant end node 2f, least significant end node 2f is connected on the frame part 2g of metallic plate 2.At least significant end economize on electricity 2f, the end (one and of Figure 30 (c) middle right side in Figure 30 (a) on the left of) of metallic plate 2 on Width is directly connected on the frame part 2g, and the other end is cut by the recess 1b of least significant end dise knife 1 in the last dise knife roller, and is cut by the recess 1b of the least significant end dise knife 1 except that least significant end dise knife 4 in the lower wall rotor.In fact the other end is pressed on the cutting planes S by the recess 1b of last dise knife 1.Thus, in the metallic plate 2 that transports on transportation surface, the distortion of the other end of least significant end node 2f is by 50% of downward pressing plate thickness.On the contrary, with the same way as of prior art, in common node 2c, one and another end be by vertical pressing, and surpass identical cutting planes S, on direction up and down, 100% or bigger distortion of thickness takes place like this.And at least significant end node 2f, the part on the recess 4b of least significant end dise knife 4 slightly is bent downwardly along intilted surperficial 4d from transportation surface, so the further slight deformation of the other end.
At the recess 4b of least significant end dise knife 4 is not to form under the situation of least significant end node of recess, be the groove 1c (left distal end among the right end among Figure 30 (a) and Figure 30 (c)) that recess is faced the last dise knife 1 recess 1b that closes on, the end of metallic plate 2 frame part 2g, the recess 1b by least significant end dise knife 1 in the last dise knife roller cuts.And at the end of frame part 2g, the part on the recess 4b of least significant end dise knife 4 is from the transportation surface slight bending along outward-dipping plane 4e.
Under the situation that the protrusion 1a of up and down dise knife 1 overlaps each other, shown in Figure 30 (b), up and down dise knife 1 cutting that metallic plate 2 is closed on, and form slit 2a, and the lead 2b between the 2a of slit is by the protrusion 1a vertical pressing of dise knife 1.In the identical mode of prior art, lead 2b is pressed to the shape of vertical crowned along the transporting direction of metallic plate 2.Metallic plate 2 on the least significant end dise knife 4, the last dise knife 1 that is inwardly closed on cuts, and forms the end of frame part 2g, and is made progress by protrusion 4a, pushes to cutting planes S, and press degree is 50% of a plate thickness.
In the subsequent step of rotary underreamer, wherein form the metallic plate 2 of a lot of slit 2a as mentioned above, on Width, extend to both sides.As a result, as shown in figure 33, slit 2a broadening and form screen forms latticed screen thus, and wherein four lead 2b pulling out by inclination of node 2c and least significant end node 2f are connected to each other.In Figure 33,, omitted the distortion of node 2c and lead 2b equally, and shown screen with diagram with the same way as of Figure 50.
According to this structure, the vertical deformation of least significant end node 2f is approximately half of plate thickness in the metallic plate 2.Thus, the stress that has reduced among the least significant end node 2f is concentrated.Even as the result of processing, after lead 2b pulls out obliquely, at least significant end node 2f corrosion or heating take place hardly, and compare with common node 2c, lead almost not have the chance that ruptures.Because the lead 2b of the most close metallic plate 2 frame part 2g ruptures hardly, can prevent really that the capacity of lead accumulator from reducing in a large number.
In the present embodiment, described such situation, promptly as the recess 1b that forms recess least significant end node, its most external radius differs 50% of metallic plate 2 thickness less than predetermined radius.Yet this species diversity is not limited to 50% of plate thickness, as long as the most external diameter is less than predetermined radius.The degree that reduces when the predetermined radius of most external radius ratio more hour, the vertical deformation amount of least significant end node 2f is bigger.On the contrary, when the little degree of the predetermined radius of most external radius ratio was big, except forming the least significant end node of recess, the difference of the vertical-horizontal of cutting part became big especially among the metallic plate 2 recess 1b.The radius predetermined when the most external radius ratio is little, phase difference plate thickness 100% or when bigger, the peripheral side of recess 1b can not be supported the least significant end node 2f of metallic plate 2, its center dant 1b is the most external node that forms recess.Preferably the most external radius of recess 1b is provided with thus, differs 30% to 70% of metallic plate 2 thickness, or in the littler scope, its center dant 1b is the node that forms recess less than predetermined radius.
In the present embodiment, described such situation, promptly the peripheral side of least significant end dise knife 4 protrusion 4a is as the circle of reference perimeter surface.Perhaps, as shown in figure 34, the peripheral side of protrusion 4a can form the inclined-plane, and this inclined-plane is similar to the least significant end node outward-dipping surperficial 4e in addition that recess 4b forms recess.In selection, the peripheral side of least significant end dise knife 4 protrusion 4a, with the recess 4b beyond the formation recess least significant end node, form identical inclined-plane, and the surface that slopes inwardly of Qing Xieing in an opposite direction, only form in the peripheral side of recess 4b, its center dant 4b is the least significant end node that forms recess.
In the present embodiment, described such situation, promptly intilted surperficial 4d and outward-dipping surperficial 4e are formed in the peripheral side of least significant end dise knife 4 recess 4b.Perhaps, as shown in figure 35, each peripheral side of recess 4b can be made of circumferential surface.In Figure 35, the peripheral side of recess 4b (left end among Figure 35) is made of such circumferential surface, the radius that its radius ratio is scheduled to is little, 100% of phase difference plate thickness, wherein above-mentioned recess 4b is the least significant end node that forms recess, and except the least significant end node that forms recess, the peripheral side of other recess 4b (Figure 35's is right terminal) is the circle of reference perimeter surface of predetermined radii.For example, the peripheral side of recess 4b can be made of such circumferential surface, and the radius that its radius ratio reference planes are scheduled to is little, and 50% of phase difference plate thickness, wherein above-mentioned recess 4b are the least significant end nodes that forms recess.Compare with the slope inwardly situation of plane 4d of formation, as in the present embodiment, in this case, least significant end node 2f flip-flop among a small circle.Although the vertical deformation amount of least significant end node 2f is identical, node the dise knife roll shaft make progress more among a small circle in flip-flop.In the present embodiment, groove 4c is not formed in the least significant end dise knife 4.Under groove 4c also was formed on situation in the least significant end dise knife 4, as in the prior art, the inboard of recess 4b peripheral side was with stepped sinking.Even when peripheral side is made of such circumferential surface, wherein the radius of circumferential surface is less than the predetermined radius of circle of reference perimeter surface, 50% of phase difference plate thickness, and thus, the least significant end node is distortion suddenly.Just, with slope inwardly surperficial 4d and the identical mode of outward-dipping surperficial 4e of present embodiment center dant 4b, the ladder that causes owing to groove 4c allows metallic plate 2 smooth deformation.
As mentioned above, the peripheral side of recess 4b only need have outermost diameter, and this most external diameter is less than predetermined diameter, and needs not be circumferential surface, and wherein above-mentioned recess 4b is the most external node that forms recess.Peripheral side can be in fact along the plane that circumferential surface extends, and can be the conical surface in the present embodiment, or the smooth clinoplain that in fact extends along conical surface.Perhaps, peripheral side can have stair-stepping shape, as in the situation that forms groove 4c, perhaps can be the arbitrary surface or the surface of other kind.On the contrary, among the recess 4b beyond forming recess least significant end node, in order to cut metallic plate 2, wherein metallic plate 2 interrelates with the recess 1b of last dise knife 1, and the outer radius of interior extremity must be greater than predetermined radii at least, and surpasses cutting planes S.As long as satisfy such condition, form recess least significant end node recess 4b in addition, can constitute by the plane of any kind of.
In the present embodiment, described such situation, promptly the peripheral side of least significant end dise knife 4 protrusion 4a is the circle of reference perimeter surface of predetermined radii.Perhaps, as shown in figure 36, the peripheral side of protrusion 4a can constitute by the circumference side, and the radius that the radius ratio of the circumference side of formation protrusion 4a peripheral side is scheduled to is little, 50% of phase difference plate thickness.In selection, the peripheral side of protrusion 4a has certain radius, and its value equals the slope inwardly outmost radius of external end of surperficial 4d of recess 4b, and wherein the inside inclined-plane 4b of protrusion 4b is the least significant end summit that forms recess in the present embodiment.Same protrusion 4a must cut the metallic plate 2 that the protrusion 1a with last dise knife 1 interrelates.Because the protrusion 1a of last dise knife 1 raises into the shape of crowned downwards, can form down the peripheral side of dise knife 1 protrusion 4a, as such circumferential surface, its radius is less than predetermined radius.Yet, little to the amount of lower convexity in two base area of last dise knife 1 protrusion 1a, like this, a kind of possibility is arranged in this zone, the radius of protrusion 4a peripheral side must increase, thus cutting metal plate 2.
In the present embodiment, described such situation, promptly least significant end dise knife 4 is placed on two ends of lower wall rotor separately.Perhaps, the one or both ends of least significant end dise knife 4 can be placed on the one or both ends of dise knife roller.Can use two pairs or more to the dise knife roller.For example, metallic plate 2 can pass three dish-type rotors of layout.
In the present embodiment, describe such situation, promptly formed in the metallic plate 2 and be connected to the lead 2b on the least significant end node 2f and be connected to lead on another node 2c, thereby had identical thickness.Perhaps, the lead 2b that is connected on the least significant end node 2f can form thickly especially, thereby lead 2b more can not rupture.
In the present embodiment, described such situation, promptly handled metallic plate 2 and produce the screen be used in the lead accumulator cell panel.The invention is not restricted to lead accumulator, and can be applied to the storage battery of any kind of, as long as similar screen is as the electric current collection parts of cell panel.Can produce screen by the metallic plate of suitable material, suitable like this material is corresponding to the kind of battery.
