The specific embodiment
With reference to the accompanying drawings the preferred forms of the manufacture method of annular component of the present invention is described below.
As shown in Figure 1, on one side will stipulate thickness of slab base material 2 shown in arrow P like that the length direction to this base material 2 carry, one side is separated the blank 3 of the die-cut a plurality of lengthwise ring-types that are partitioned into row of regulation along throughput direction by decompressor.As base material 2, can use by metal bar such as copper, aluminium, iron, stainless steel by the base material of making plate body such as rolling, perhaps use the base material that originally is plate body.
As shown in Figure 2, have the hole 3a that width dimensions is the little lengthwise of w1 in the inboard of the blank 3 of lengthwise ring-type, the blank 3 of this lengthwise ring-type has: a pair of circular- arc 3d, 3d, and establish in opposite directions at its two ends at longitudinally; Connecting portion 3b, the 3c of pair of straight wire, establish in opposite directions its horizontal both sides about vertical with longitudinally, is used for being connected with each other between the end with a pair of circular- arc 3d, 3d.
The blank 3 of this lengthwise ring-type is arranged in the first mold pressing processing unit (plant) 4 as shown in Figure 3.The first mold pressing processing unit (plant) 4 has pair of right and left movable plate 5, a pair of guided plate 6 of a pair of shaping external mold 8 in front and back and front and back.Pair of right and left movable plate 5 is by guided plate 6 guiding and utilize not shown driving and reversing mechanism to advance and retreat along left and right directions (arrow X1, X2 direction).About the front end of each movable plate 5, project upwards and be provided with projection plane and be shaped as the shaping internal mold 7 that the back side is the dome arc shape, about this shaping internal mold 7,7 erect be arranged on with the perpendicular straight line Y of straight line X be benchmark and symmetrical position, make the flat front surface of two internal molds lump together mutually, the described shaping internal mold that lumps together 7,7 the width dimensions w2 of the described shaping internal mold that lumps together 7,7 is set at the size of the width dimensions w1 of the hole 3a that is slightly less than this lengthwise, so that can be embedded among the hole 3a of lengthwise of blank 3.
The a pair of shaping external mold 8 in front and back is by guided plate 6 guiding and utilize not shown driving and reversing mechanism to advance and retreat along fore-and-aft direction (arrow Y1, Y2 direction).Have outstanding vertically upward be provided with and projection plane is shaped as the pushing face 8a of circular-arc depression at the front end of the external mold 8 that respectively is shaped of front and back, the radius of curvature of this pushing face 8a is set at value greater than the radius of curvature of the outer peripheral face of circular-arc 3d in the blank 3 of lengthwise ring-type.
The a pair of shaping external mold 8 in front and back is established on straight line Y mutually in opposite directions, and being configured in straight line X is on the position of benchmark and front and back symmetry, both intervals in opposite directions are set at greater than the size value on the longitudinally of the blank 3 of lengthwise ring-type, so that can allow the arrangement of the blank 3 of lengthwise ring-type.
As shown in Figure 3, when the blank 3 of lengthwise ring-type is set in the first mold pressing processing unit (plant) 4, the patrix of representing with double dot dash line 9 is descended from the top.Thus, guided plate 6, a pair of shaping external mold 8 of pair of right and left shaping internal mold 7 and front and back upper surface are separately pushed by the lower surface of patrix 9, the upper surface that makes blank 3 and shaping internal mold 7 and shaping external mold 8 and the lower surface of patrix 9 be across minimum gap (allowing the little gap of slip) and relative, is upturned at upper and lower to prevent blank 3.
Under this state, make move left and right plate 5 respectively about vertical with the longitudinally of blank 3 the horizontal outside (arrow X1 direction) move, simultaneously, the shaping external mold 8 before and after making moves to the inboard of longitudinally (arrow Y1 direction) respectively.So, about connecting portion 3b, the 3c of left and right sides both lateral sides of blank 3 of 7 pairs of lengthwise ring-types of shaping internal mold move and (arrow X1 direction) pushing from its inboard laterally, making this connecting portion 3b, 3c expand to arrow X1 direction with big as shown in Figure 4 radius of curvature opens, and, before and after circular-arc the 3d at longitudinally two ends of 8 pairs of blanks 3 of shaping external mold move and from inboard, lateral (arrow Y1) pushing of the longitudinally of blank 3, make this circular-arc 3d to expand out than the big radius of curvature of radius of curvature of circular-arc the 3d of Fig. 3.Thus, produce the following annular component 1A that is oval ring-type as shown in Figure 4, that is, this annular component 1A has: radius of curvature is greater than circular-arc 3D of a pair of expansion of the radius of curvature of circular-arc the 3d of Fig. 3; Continue with circular-arc 3D of a pair of expansion and arch upward and be bent into circular-arc a pair of connecting portion 3B, the 3C of arching upward with bigger radius of curvature.
As mentioned above, by the blank 3 of base material shown in Figure 12 die-cut a plurality of lengthwise ring-types, the blank 3 of these lengthwise ring-types utilizes the first mold pressing processing unit (plant) 4 to form, and produces annular component 1A shown in Figure 4 thus.Therefore, by the lower blanking of ratio that the frame waste material S1 of Fig. 1 and punched scrap S2 can be suppressed more illustratedly with respect to Figure 11 than frame waste material S1 and punched scrap S2 annular component 1 with respect to the ratio of annular component 1A, can improve as the yield rate of annular component 1 weight with respect to the ratio of base material 2 weight, thus the cost of reduction annular component 1A.
In addition, carry out the pushing of from the horizontal to the left and right outside, its inboard (arrow X1 direction) so that it expands to as shown in Figure 4 arrow X1 direction opens by connecting portion 3b, 3c to the left and right sides both lateral sides of the blank 3 of lengthwise ring-type, simultaneously, also it is carried out from the pushing of (the arrow Y1 direction) of the inboard, lateral of the longitudinally of blank 3 so that it expands by the radius of curvature bigger than the radius of curvature of circular-arc 3d opens; " extension " phenomenon takes place in the little radially inner side zone of radius of curvature that can do one's utmost like this to suppress among circular-arc the 3d of blank 3, produced the result and be and not only can avoid the generation of radially inner side zone thin-walled property even can also make flowing of the such material of circular-arc 3d wall thickening, slowed down the stress in radially inner side zone like this and concentrate.Consequently, make circular-arc 3d crack performance can not take place, and can improve annular component 1A with respect to the ratio of lengthwise ring-type blank 3, be yield rate.
Shaping internal mold 7 further moves to arrow X1 direction respectively from the state of the first mold pressing processing unit (plant) 4 shown in Figure 4 about making, so that connecting portion 3b, the 3c of blank 3 open from its inboard expansion, and, shaping external mold 8 before and after making moves to arrow Y1 direction, open so that circular-arc 3d of blank 3 is pushed companding, can be configured as more approaching circular shape thus than the observed annular component 1A of Fig. 4.
A pair of shaping external mold 12 and pair of right and left restriction mould 13 before and after the second mold pressing processing unit (plant) 11 has.Shaping external mold 12 is by guided plate 14 guiding and utilize not shown driving and reversing mechanism and direction (arrow Y1, Y2 direction) advance and retreat forwards, backwards, and restriction mould 13 is by guided plate 14 guiding and utilize not shown driving and reversing mechanism and direction (arrow X1, X2 direction) advance and retreat to the left and right.
Before and after a pair of shaping external mold 12 have: mounting surface 12a and be provided with and projection plane is shaped as the pushing face 12b of circular-arc depression from mounting surface 12a is outstanding vertically upward, the radius of curvature of this pushing face 12b is set at radius of curvature greater than the outer peripheral face of circular-arc the 3D of expansion among the annular component 1A shown in Figure 4, and forms with shown in Figure 6 circular or be similar to the corresponding such circular-arc pushing face 12b of an outer peripheral face part of the annular component 1 of circular polygon.In addition, on pair of right and left restriction mould 13, with the end face of in opposite directions the relative side of restriction mould on be formed with the restriction face 13a that the projection plane shape is circular-arc depression, the radius of curvature of this restriction face 13a is set at value less than the radius of curvature of the outer peripheral face of arch upward connecting portion 3B, 3C among the annular component 1A shown in Figure 4, and forms with shown in Figure 6 circular or be similar to the corresponding such circular-arc pushing face 12b of an outer peripheral face part of the annular component 1 of circular polygon.
As shown in Figure 5, restriction mould 13 clips arch upward connecting portion 3B, the 3C of annular component 1A about use, and with circular-arc 3D of the expansion of this annular component 1 and near the part mounting under the state on the mounting surface 12a of shaping external mold 12, when being placed in annular component 1A in the second mold pressing processing unit (plant) 11, the patrix of representing with double dot dash line 15 is descended from the top.Thus, each upper surface that makes annular component 1A and shaping external mold 12 and restriction mould 13 and the lower surface of patrix 15 are across minimum gap (being used to allow the little gap of slip) and relative, in case stop ring shape member 1A direction perk up and down.
Under this state, shaping external mold 12 is moved to arrow Y1 direction.So the pushing face 12b of shaping external mold 12 carries out the pushing of outside-in to circular-arc 3D of the expansion of annular component 1A, it is expanded with big radius of curvature open.Thus, the radially-outer surface that two of annular component 1A enlarges circular-arc 3D is that circular-arc pushing face 12b pushes in the lateral by the depression by shaping external mold 12, and it is deformed along this pushing face 12b, as shown in Figure 6, thereby be configured as radius of curvature than enlarging circular-arc circular-arc 3E of expansion that the 3D radius of curvature is bigger, in this radial outside zone that enlarges circular-arc 3E " extension " phenomenon takes place like this, " extension " phenomenon takes place and do one's utmost to have suppressed the radially inner side zone, having produced the result is not only can avoid the wall thickness attenuation in radially inner side zone even can make flowing of the such material of circular-arc 3E wall thickening of expansion, slowed down the stress in radially inner side zone and concentrated, thereby made circular-arc 3E of two expansions can not produce be full of cracks.
In addition, when making two to enlarge circular-arc 3E shaping, also make the connecting portion 3B that arches upward of annular component 1A shown in Figure 5,3C opens to the expansion of arrow X1 direction, but this moment is by making the connecting portion 3B that arches upward, the depression of the outer surface of 3C and restriction mould 13 is that circular-arc restriction face 13a connects, so that opening to the unnecessary expansion of arrow X1 direction, annular component 1A is restricted, and along the corresponding distortion of this restriction face 13a generation, be configured as the arch upward connecting portion 3B of radius of curvature thus than annular component 1A shown in Figure 4, the circular-arc connecting portion 3F that arches upward that the radius of curvature of 3C is little, 3F, thus it is consecutive as Fig. 6 and circular annular component 1 shown in Figure 9 with the connecting portion 3F that arches upward to make circular-arc the 3E of described expansion that send as an envoy to.
When being configured as circular annular component 1 like this, can do one's utmost suppress to enlarge circular-arc 3D and arch upward connecting portion 3B, 3C in the radially inner side zone " extension " phenomenon take place, avoid the wall thickness attenuation in radially inner side zone, and the stress that slows down the radially inner side zone is concentrated.Consequently, can make sends as an envoy to enlarges circular-arc 3D and arch upward connecting portion 3B, 3C do not produce the annular component 1 of be full of cracks, therefore, can improve annular component 1 with respect to the ratio of the blank 3 of lengthwise ring-type, be yield rate.
In said embodiment, as shown in Figure 2, can be punched to the blank 3 of the less lengthwise ring-type of the width dimensions w1 of vertical slot hole 3a, and this blank 3 is fabricated to annular component, but also can be as shown in Figure 7, die-cut blank 27 with width dimensions w3 than the lengthwise ring-type of the big a lot of elliptoid vertical slot hole 27a of the width dimensions w1 of Fig. 2, and this blank 27 is configured as annular component with the step identical with described embodiment.Even in this case, also can with above-mentioned embodiment similarly improve annular component with respect to the ratio of the blank 27 of lengthwise ring-type, be yield rate, thereby can reduce the cost of annular component.
In addition, from the blank of base material 2 die-cut a plurality of lengthwise ring-types of Rack 3,27 o'clock, shown in the (a) and (b) among Fig. 8, effectively utilize the width both ends of the surface 2a of base material 2 to form the linearity connecting portion 3b of the blank 3,27 of lengthwise ring-type, the outer face of 3c, and, use decompressor that base material 2 is cut off, can be formed for a pair of circular-arc the 3d that pair of straight wire connecting portion 3b, 3c are continued mutually thus at the both ends of length direction.Thus, can become waste material is suppressed to be MIN blanking with respect to the ratio of the blank 3,27 of lengthwise ring-type.That is when, described waste material is reduced to die-cut vertical slot hole 3a or elliptoid vertical slot hole 27a by the die-cut punched scrap S1 that removes of stamping machine and as in the (a) and (b) among Fig. 8 with such shown in the oblique line, arrange and between the blank 3 that cuts off the lengthwise ring-type of opening from base material 2 or the 2x of end plate portion of the cydariform that exists between the blank 27 along its length.Consequently, can further improve the weight of annular component 1 with respect to the ratio of the weight of base material 2, be yield rate.
