Detailed description of the invention
Be described with reference to the roller trough of Fig. 1 ~ Fig. 6 to an embodiment.The present invention is not limited to following embodiment, can change its part as required.In addition, in the following description, if direction does not specialize up and down, the direction in figure is referred to.In addition, in Fig. 3 ~ Fig. 6, kayser C and the handle sectional fixture H of diagram roller trough 01 is omitted for simplicity.
(structure of roller trough)
Fig. 1 (A) is the partial sectional view of the roller trough schematically representing an embodiment, and Fig. 1 (B) is the top view of the main body of the roller trough of an embodiment.The roller trough of an embodiment is a kind of centrifugal drum grinder cylinder, and it comprises main part and cap, and this main part comprises side and the bottom surface of tubular, and marks off grinding space by main part and cap.The entirety of the entirety of main part (main body 10) or cap (lid 20) is made up of the rubber imparting abrasion resistance properties of an embodiment of resin.Below, the roller trough 01 shown in Fig. 1 (A), Fig. 1 (B) is described in detail.
As shown in Fig. 1 (A), roller trough 01 is configured to the lid 20 of the main body 10 of the drum comprising upper end open and the drum of lower ending opening.Main body 10 has sidepiece SW and bottom BW.Sidepiece SW comprise the outer space of agent-oriention 10 sidepiece lateral surface 13 and as the sidepiece medial surface 15 be positioned at than sidepiece lateral surface 13 face in the inner part.Bottom BW is connected to the lower end of sidepiece SW, and comprise the outer space of agent-oriention 10 bottom outside face 14 and as the bottom inside face 16 be positioned at than face in the inner part, bottom outside face 14.And, form the space and recess 11 that are impaled by sidepiece medial surface 15 and bottom inside face 16 in the main body 10.
Similarly, lid 20 has: sidepiece SP, and it comprises towards the sidepiece lateral surface 23 of the outer space of lid 20 and as being positioned at than sidepiece lateral surface 23 face in the inner part and sidepiece medial surface 25; And top T P, it is connected to the upper end of sidepiece SP, and comprises towards the top outside 24 of the outer space of lid 20 and as being positioned at than top outside 24 inside top face 26 in the inner part.And, in lid 20, be formed with the space and recess 21 that are impaled by sidepiece medial surface 25 and inside top face 26.
When carrying out cylinder grinding, the upper surface 12 of main body 10 is close to the lower surface 22 of lid 20 becomes columnar container.In the inside of roller trough 01, form space that is continuous and sealing by the recess 11 of main body 10 and the recess 21 of lid 20 and namely grind space S.That is, the side of grinding in space S is the face formed by sidepiece medial surface 15 and sidepiece medial surface 25, and bottom surface is bottom inside face 16, and end face is inside top face 26.
Grinding space S is the space loading blocks when carrying out cylinder grinding.By making the plan view shape (cross section in Fig. 1 (A)) of grinding space S be polygon, and make blocks fluidization become easy, thus grainding capacity improves.As long as blocks fluidization can be made just without particular limitation of the shape of grinding space S, but be formed as eight prism shapes in the present embodiment as shown in Fig. 1 (B).
Whole bights of grinding space S (the octagonal bight of cross section, the bight formed by the face orthogonal with above-mentioned octagon and side and the face orthogonal with this side and bottom surface and end face) are all formed as curved surface.That is, the cross section of inwall towards grinding space S be polygon-shaped, and in inwall, become the bight on polygonal each summit, the bight formed by sidepiece SW and bottom BW and by sidepiece SW and cover the curvature that 20 bights formed have regulation.In addition, the curvature in these bights also can be different.When bight is not formed as curved surface, when carrying out cylinder grinding, machined object enters bight and is detained, and thus sometimes produces grinding inequality or produces situation that is cracked or crack equivalent damage when cylinder grinds at machined object.On the other hand, by bight is formed as curved surface, grinding can be suppressed uneven.The radius of curvature of this curved surface can be selected from R10mm ~ 50mm.If R is too small, produces because of the delay of machined object and grind inequality, if R is excessive, because the flow regime of blocks produces grinding inequality in the equal difference in the place in each grinding space.In addition, be also formed with a part for the side of grinding space S at lid 20 if be configured to, then whole bights of grinding space S all can be formed as curved surface.
Main body 10 and lid 20 are formed by resin.Herein, so-called resin, refers to the concept of the macromolecular material comprising rubber and so on.As long as resin meets following necessary condition just without particular limitation of its material: when being fixed on roll grinding machine, profile is indeformable to more than required, when cylinder grinds, internal face is indeformable to more than required, internal face is not really up to the mark to more than required, and the mar proof of internal face is strong.Use the hardness measured by the De Sailuo (type A) of regulation in JIS6253-3 (2012) to be A30 ~ A90 in the present embodiment, and impart the rubber (mar proof rubber) of mar proof.If hardness is too low, then absorb the impulsive force of more than necessity when the internal face of blocks and roller trough 01 collides, thus become the reason that grinding efficiency is deteriorated, grinding is uneven.If much higher hard, then the wearing and tearing of roller trough 01 accelerate because of above-mentioned impulsive force.Though mar proof rubber has NR (natural rubber), BR (butadiene rubber), SBR (styrene butadiene ribber), NBR (acrylonitrile-butadiene rubber) etc., the hardness needed for roller trough 01 or the suitably selection such as mar proof or resistance to chemical reagents can be considered.
But, even if the situation that use mar proof rubber also cannot avoid internal face to wear and tear because cylinder grinding.If wearing and tearing progress, grinds the alteration of form of space S, thus finishing stage changes.Therefore, new roller trough 01 must be replaced by before affecting finishing stage.Therefore, between sidepiece lateral surface 13 and sidepiece medial surface 15 and between bottom outside face 14 and bottom inside face 16, be provided with the marker slip 17 of replacing construction for knowing roller trough and the limit of wear.Marker slip 17 is embedded in the position that have left predetermined distance t from the internal face of main body 10.Predetermined distance t coordinates the shape etc. in the material of main body or grinding space to set.The predetermined distance t of present embodiment is selected between 3 ~ 10mm.In addition, in the example shown in Fig. 1 (A), though marker slip 17 to be embedded in the both sides of sidepiece SW and bottom BW, either party in sidepiece SW and bottom BW can be also only embedded in.In addition, marker slip 17 also can be embedded in sidepiece SP or the top T P of lid 20.
As long as marker slip 17 is embedded in the position that have left predetermined distance t from internal face, such as, can be selected from the cloth of wire netting, nylon or cotton etc., film etc.The appearance of marker slip 17 can be confirmed when changing blocks.That is, owing to cannot confirm in process of lapping, so the state being exposed to internal face with marker slip 17 marker slip 17 occurs in process of lapping carries out cylinder grinding.Low or low with the bonding force of the material of main body in the intensity of marker slip 17, a part for marker slip 17 is mixed into blocks because of cylinder grinding, thus it becomes pollutant.In addition, if much higher hard, when cylinder grinds, machined object is impaired because of marker slip 17.The marker slip 17 of present embodiment selects the cloth be made up of nylon.
In one embodiment, for improving the sealing (seal) of grinding space S, in the upper surface (composition surface in space) 12 of main body 10, protuberance 18 outstanding is upward formed with.Protuberance 18 is made up of the material identical with main body 10, has the elastic force of appropriateness.According to this protuberance 18, when making lid 20 be crimped on main body 10, protuberance 18 coordinates the shape of the lower surface 22 of lid 20 and is out of shape, and thus main body 10 improves with the close property of lid 20.In addition, protuberance 18 also can be formed at the lower surface 22 of lid 20.In this case, protuberance 18 is formed in the mode of giving prominence to downward from the lower surface 22 of lid 20.
Protuberance 18 is to arrange along the mode of sidepiece medial surface 15, and outer rim is formed as circular.And, be bonded with deformation restricting portions part 19 in the periphery of protuberance 18.If more than needed for protuberance 18 is deformed into peripheral direction, then produce jump in main body 10 and the border of lid 20.This jump becomes the uneven reason of grinding.By arranging deformation restricting portions part 19, the distortion more than needed for occurring towards peripheral direction can be prevented.As long as deformation restricting portions part has the intensity suppressing protuberance to be out of shape towards peripheral direction as far as possible, its material to be selected from metal, plastics, pottery etc.Use the plate of metal toroidal in the present embodiment.
In addition, in this deformation restricting portions part 19, towards the sagging jig-attachment part part 19a being provided with drum, it can the lateral circle surface top of outsourcing main body 10.As long as the length of jig-attachment part part 19a installs the length of kayser C described later or handle sectional fixture H.
The external diameter of the sidepiece SW in main body 10 reduces continuously towards bottom.As described later, when cylinder grinds, roller trough 01 can not offset relative to its position of roller trough shell, and in addition, the handling of roller trough 01 become easy.In the present embodiment, sidepiece SW is selected from the scope of 1 ~ 5 ° relative to the angle of inclination in the direction perpendicular to bottom BW.
Pressing bearing part 29 is bonded with at the upper surface of lid 20.Pressing bearing part 29 can prevent as described later when lid 20 being pressed on main body 10 cover 20 top (, top outside 24) situation of being out of shape, and the power of pressing can be additional to equably the lower surface 22 composition surface of main body 10 (that is, with) of lid 20.
In addition, press bearing part 29 and kayser C described later also can be installed.
In addition, be provided with for determining the detent mechanism of lid 20 relative to the position of main body 10 in main body 10 or lid 20.That is, this detent mechanism is the mechanism of the relative position of stationary body 10 and lid 20.By detent mechanism, the shape of grinding space S can be formed as eight prism shapes.As long as detent mechanism can determine that the position of lid 20 relative to main body 10 is just without particular limitation of its structure.Such as, can be formed as erecting arrange pin or protuberance in the lower surface 22 of the upper surface 12 of main body 10 or lid 20, and at the structure that the opposing party arranges hole or the recess that can be fitted together to for this pin or protuberance, also can be formed as other known structure.In the present embodiment, as detent mechanism, multiple pin P is fixed in the upper surface 12 along main body 10, and arranges the chimeric hole h of supply and marketing P in the lower surface 22 of lid 20.
In addition, be fixed with fixed mechanism in main body 10 and lid 20, it is close to for making main body 10 and lid 20 when roller trough 01 is positioned over centrifugal drum grinder.When roller trough 01 is positioned over centrifugal drum grinder, as long as can with the degree making blocks can not spill from roller trough sealing grinding space just without particular limitation of its structure.Such as, the parts of kayser and so on can be used, rubber strip etc. also can be utilized to link main body 10 and lid 20, also can be formed as other known structure.In the present embodiment, the kayser C as fixed mechanism is equally spaced fixed on 4 positions.
