摘要

It solves the problems, such as: a kind of die device and a kind of punching method lamellar material is provided, can inhibit and prevent bending stripper in impact missing, structure is simple. ;SOLUTION: die apparatus 10 includes: a kind of for punching press punch-pin and cavity plate processing sheeting 11; And one stripper 12 be arranged in punch-pin, and in male and female mould. Stripper 12 includes protrusion 22, for inhibiting the signal for being bent the generation of strip teaser 12 in impact missing. The material of the punching method thin slice is configured to: compressing sheeting 11 and cavity plate and stripper 12 is arranged in punch-pin; Then,Punching processing and formpiston and former are carried out, wherein the projection part 22 is placed on strip teaser's impact missing for generating during the bending that stripper 12 inhibits 12. ;In selected attached drawing: attached drawing 1;COPYRIGHT:(C) 2017, JPO& INPIT
