Abstract

A blanking die of a base angle holder comprises a lower die holder, a convex die, an unloading plate, a concave die, a push plate, a liner plate, an upper die holder, a die handle, a knock-out rod, a guide pillar (A) and a guide pillar (B). The lower die holder, the convex die, the unloading plate and the guide pillar (A) are connected with one another through bolts, the concave die, the push plate, the upper die holder and the guide pillar (B) are connected with one another through bolts, the upper die holder and the die handle are formed in a casting way, and the knock-out rod is connected with the liner plate through a nut. The bottom of the concave die is designed into an oblique knife edge. Since the concave die adopts the oblique-knife-edge design, the traditional 300-ton punching machine is changed to the 160-ton punching machine, so that the cost and the energy consumption can be saved.

Description

A kind of base angle bearing blanking die

Technical field

The present invention relates to the technical field of mold of auto parts machinery, be specifically related to a kind of base angle bearing blanking die.

  

Background technology

At present, what the groove of blanking die used is the flat edge of a knife, uses so larger blanking pressure just can satisfy the demand.

  

Summary of the invention

The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of efficient, base angle, labour-saving bearing blanking die is provided.

A kind of base angle bearing blanking die includes following assembly: die shoe, punch, stripper, die, scraping wings, liner plate, upper bolster, die shank, knockout rod, guide pillar () and guide pillar (two).Connect with bolt between die shoe, punch, stripper, the guide pillar (), connect with bolt between die, scraping wings, upper bolster, the guide pillar (two), upper bolster and die shank casting, knockout rod is connected with the liner plate nut.

Described die bottom design becomes the oblique edge of a knife.

Effect of the present invention is high, conservation of power.
