The specific embodiment
below in conjunction with accompanying drawing and specific embodiment, technical scheme of the present invention is further elaborated.
referring to the mould shown in Fig. 1-2, this mould comprises that die shoe 2 can vertically be arranged on the upper bolster 1 on die shoe 2 up and down with relative die shoe, on upper bolster 1, be provided with on patrix 3, die shoe 2 and be provided with counterdie 4, workpiece to be processed 5 is between patrix 3 and counterdie 4.On upper bolster 1, be permanently connected and be provided with the first wedge 6, the medial surface of the first wedge 6 and intersection, bottom surface form the first inclined-plane having a down dip gradually from inside to outside, and the lateral surface of the first wedge 6 and intersection, described bottom surface form from inside to outside the second inclined-plane of updip gradually.Here inside and outside, refer to the interior lateral direction of mould, toward mold center position, be in, be on the contrary outside.
shown in Fig. 1-2, on die shoe 2, be provided with the take-up housing 7 can along continuous straight runs sliding, on die shoe 2, be also permanently connected in the present embodiment and be provided with the slide block baffle plate 14 that can keep out the outer end of take-up housing 7, the outer end of this slide block baffle plate 14 and take-up housing 7 is by providing the setting that is connected of the second elastic component 15 of take-up housing 7 horizontal direction elastic-restoring forces, and what the second elastic component adopted here is spring.In the outboard end of take-up housing 7, be permanently connected and be provided with the second wedge 8, the end face of the second wedge 8 forms the 3rd inclined-plane that can match with the second inclined-plane with medial surface intersection, orders about take-up housing 7 along continuous straight runs on die shoe 2 slide by the second inclined-plane and the change that coordinates situation on the 3rd inclined-plane.A bend bar 9 has been permanently connected on the medial end of take-up housing 7, on take-up housing 7, be provided with a Bending Slide Block that is used to form bound edge on workpiece to be processed 5 11 that can match with above-mentioned bend bar 9, Bending Slide Block 11 can along continuous straight runs be slidably arranged on take-up housing 7 between bend bar 9 and the second wedge 8.The end face of Bending Slide Block 11 and lateral surface intersection form the 4th inclined-plane that can match with the first inclined-plane on the first wedge 6, and Bending Slide Block 11 situation that along continuous straight runs slides on take-up housing 7 depends on the situation that coordinates on the first inclined-plane and the 4th inclined-plane.Because the first inclined-plane on the first wedge 6, the second inclined-plane need to match with the 4th inclined-plane, the 3rd inclined-plane respectively, the first wedge 6 is set in the horizontal direction between the second wedge 8 and Bending Slide Block 11.The 4th inclined-plane should be lower than the 3rd inclined-plane at vertical direction, and like this, thereby the first wedge 6 can first match with the second wedge 8 to coordinate with Bending Slide Block 11 to complete again the bending of workpiece to be processed 5 side portion is formed to bound edge.On the medial end of Bending Slide Block 11, be also connected with the block 12 that can keep out the outer side edges portion of workpiece to be processed 5, in the present embodiment, between block 12 and Bending Slide Block 11, by one, can provide the setting that is connected of the first elastic component 13 of Bending Slide Block 11 along continuous straight runs elastic-restoring forces, this first elastic component 13 is spring, can to the side portion of workpiece to be processed 5, keep out preferably like this, and the damage to workpiece to be processed 5 can prevent that stamping press is excessive time.
shown in Fig. 1-3, in the outboard end of bend bar 9, offer breach, in this breach, be connected with rotationally the swing component 10 that forms convex closure in a bound edge that can form at above-mentioned bend bar 9 and Bending Slide Block 11, swing component 10 can swing up and down and be arranged in above-mentioned breach, this breach has and can when swing component 10 swings, carry out the first spacing confined planes and the second confined planes respectively to the dual-side portion of swing component 10, be that swing component 10 swings in above-mentioned breach between the first confined planes and the second confined planes, wherein, when swing component 10 is rocked to one end side surface and conflicts on the first confined planes, bend bar 9 and Bending Slide Block 11 swing component 10 simultaneously that matches while forming on workpiece to be processed 5 bound edge forms convex closure in this bound edge.
specifically set forth below the course of work of lower the present embodiment:
shown in Fig. 1-3, workpiece to be processed 5 is between patrix 3 and counterdie 4, and bend bar 9 is positioned at the inner side of workpiece to be processed 5 simultaneously.While starting punching press, the relative die shoe 2 of upper bolster 1 is descending, the second inclined-plane on the first wedge 6 matches with the 3rd inclined-plane on the second wedge 8 and promotes the second wedge 8 and move laterally, the second wedge 8, the elastic acting force that take-up housing 7 overcomes spring 15 moves laterally, after the descending certain distance of the first wedge 6, bend bar 9 on take-up housing 7 is mobile conflict in the side portion of workpiece to be processed 5 outwards, simultaneously in the breach of swing component 10 on bend bar 9, be rocked to an end side surface and the first confined planes is inconsistent, at this moment during the first wedge 6 continuation are descending, depart from and coordinate with the second wedge 8, and the inner side edge of the outer side edges of the first wedge 6 and the second wedge 8 is inconsistent, the first wedge 6 continues descending and makes gradually the first inclined-plane on it match with the 4th inclined-plane on Bending Slide Block 11, the first wedge 6 continues descending promotion Bending Slide Block 11 and moves inward, block 12 is conflicted and in the outer side edges portion of workpiece to be processed 5, workpiece to be processed 5 is formed and kept out, the first wedge 6 matches with bending mould board 9 and forms the bound edge on workpiece to be processed 5 along with the descending continuation of upper bolster 1 is descending and promote elastic force that Bending Slide Block 11 overcomes spring 13, swing component 10 forms convex closure in this bound edge simultaneously.
when workpiece to be processed 5 is formed after bound edge and convex closure, the relative die shoe 2 of upper bolster 1 is up, the first wedge 6 is up, Bending Slide Block 11 outwards moves under the effect of the elastic-restoring force of spring 13, block 12 unclamps keeping out workpiece to be processed 5 side portion gradually, the first wedge 6 continues up, take-up housing 7, the second wedge 8 moves to the inside under the effect of spring 15 elastic-restoring forces, bend bar 9 moves thereupon to the inside, now swing component 10 bottoms are used to form the protuberance of convex closure and the inner surface of convex closure and rub mutually and drive this swing component 10 outwards to swing in breach, avoiding like this protuberance on swing component 10 to be stuck in convex closure can not move and situation that can not the material returned to the inside with bend bar 9.The bound edge place that goes upward to swing component 10 disengaging workpieces to be processed 5 when upper bolster 1 can realize the material returned.This mould structure is simple, easy to operate, has solved in existing mold having the problem of the not material returned and bending distortion in the stretching of outer casing member of convex closure bound edge, has guaranteed the quality of production of product.
