Material hitting device for red punching mould

Abstract

The invention discloses a material hitting device for a red punching mould. The material hitting device is a punch part, and ensures that a blank can be automatically demoulded without manual demoulding, ensures blank quality and improves production efficiency. The material hitting device comprises a punch arranged on a machine body, a material hitting rod is arranged in the punch and can move vertically relative to the punch, a guide structure is arranged on the machine body, and the material hitting rod can be shrunk into the punch when the blank is punched to enable the material hitting rod to stretch out of the punch and push the blank to be away from the punch. The material hitting device is mainly utilized in a red hitting machine tool.

Description

technical field [0001] The invention relates to punch parts, in particular to a punching device for a red punch die. Background technique [0002] Red stamping die is a process for metal materials to be formed by heated stamping. During processing, the heated metal blank is first put into the mold, and it is plastically deformed in the mold cavity by the stamping of the press, thereby pressing out various shapes and shapes. Pressed parts with good mechanical properties. The mechanical properties of red punching parts are good. After red punching, the metal blank is heated, extruded and cooled, and its metal structure changes, which eliminates the original defects caused by casting or drawing, so that the internal crystal structure of the part is from the inside to the outside. The linear shape improves the mechanical properties of red punched parts. During the stamping process of blanks similar to red punch bonnets and nuts and blanks that are difficult to demould, because...

AI Technical Summary

Problems solved by technology

During the stamping process of blanks similar to red punch bonnets and nuts and blanks that are difficult to demould, because the product is easy to stick to the punch, the product is backflushed and two products are stamped superimposed, resulting in damage to the punching machine and product splashing safe question

When the worker finds out, he must beat the product with a tool to release the product, resulting in scratches on the product surface and low stamping efficiency

In addition, in order to facilitate demoulding, some people deliberately increase the demoulding slope of the punch, which leads to increased loss of product materials after stamping, and also increases the workload of subsequent processing such as turning.
