Stamping die is used widely, some friends don't know how it works, then al optronics to introduce the working principle of stamping die,Blanking, the upper die through the die and punch the slider handle connected, lower die using plate fixed on the punching machine working table, up and down through the guide pin, guide sleeve, guide. Work, the material against the pin to the positioning, when the upper die with the slide block falls, stripper pressure sheet first, then convex die down concave mould material artifacts. Blanking out of round billet positioning on the lower die, pressure when the punch moves down the block, rushed out of the hole, and continue to press into the concave cavity model, make the material to produce permanent deformation in the punching die after processed into the required artifacts. When the artifact card in between the punch and the top piece, waste also tight hoop on the punch. The upper die rally, workpiece by top block by the spring of the elastic ejection from the die; Hoop on the punch waste at the same time, by the stripper by spring elastic unloading, complete the whole process. Article will material sent to another step, the next process, and so on.
