A punching method with continuous die upwards

Abstract

The invention relates to the field of stamping dies, especially the continuous die blanking method used in cold stamping production. During punching, the stripper plate goes down, so that the elastic inserts go down together, and at the same time, the spring is compressed and presses the stripper plate and the stripper plate. The material in the middle of the elastic block is then punched out. After the mold is closed, the punching is completed, the stripper plate goes up, the compressed spring returns to its original state, and the elastic block is ejected to make the material separate from the punch. Avoid the upper part of the cutting edge block, and the punched waste goes out from the empty position, and the blowing device blows the punched waste from the cutting edge block to complete the continuous upward punching of the mold, which solves the problem of special structure products. The lower die cannot be used as a cutting edge or can be made into a cutting edge, so it is very easy to chip, generate burrs, and cannot complete continuous blanking, which meets the production needs, reduces production costs, and improves production efficiency.

Description

Technical field [0001] The invention relates to the field of stamping dies, in particular to a continuous die blanking method used in cold stamping production. Background technique [0002] At present, the known stamping continuous dies are all downward punching, which has certain limitations. When encountering such a special product structure, the lower die cannot make a cutting edge or can make a cutting edge. However, it is very easy to chip, produce burrs, etc. These problems cannot meet the normal production needs, or the blanking requirements in the opposite direction cannot complete the full continuous blanking, and the single-process mold must be used to realize the product processing, resulting in low production efficiency. Manufacturing costs increase.

Problems solved by technology

[0003] Aiming at the technical insufficiency of the single punching direction of the existing die structure, the present invention provides a continuous die upward punching method, which solves the problem that for products with special structures, the lower die cannot be used as a cutting edge or can make a cutting edge and is very easy to collapse. The problems of cutting edge, burrs and inability to complete continuous punching meet the production demand, reduce production cost and improve production efficiency
