By adopting technique scheme, processing work is socketed on die, described punch moves down, be set in holding pad on punch and can first compress processing work, on upper bolster, wedge also can compress binder block simultaneously, because wedge and binder block are slidably matched, wedge can order about binder block in chute near punch side upward sliding, until conflict processing work, described punch continues to move down and carries out punching under upper bolster effect, because holding pad and binder block can compress processing work simultaneously, wherein to compress direction and the pressing direction of processing work be angled to binder block, can compress processing work from different directions, can prevent that processing work from can deform at punching course.
The utility model is further set to: described binder block is provided with the binder groove caving inward towards the end face of punch, described binder groove can be inconsistent with punch.
By adopting technique scheme, described binder block is mutually inconsistent with punch by binder groove, compresses processing work, and raising binder block compresses the effect of processing work, prevents processing work distortion.
The utility model is further set to: described binder groove is arc binder groove.
By adopting technique scheme, be convenient to the processing of binder groove, can increase arc binder groove and punch conflict area simultaneously, raising binder block compresses the effect of processing work.
The utility model is further set to: described chute is provided with fixed block away from one end of die, and described fixed block is fixedly connected with elastic component.
By adopting technique scheme, be convenient to elastic component and fix, improve installation effectiveness.
The utility model is further set to: in described chute, be provided with two slide bars, two slide bars all run through binder block, and slide bar two ends are separately fixed on the runner wall of corresponding chute.
By adopting technique scheme, described binder block slides along slide bar, can effectively improve binder block along the accuracy of sliding in chute.
The utility model is further set to: described through hole is mounting hole.
By adopting technique scheme, be convenient to pull bar through mounting hole, increase work efficiency.
