Jacking type stamping die

Abstract

The invention discloses a jacking type stamping die. The jacking type stamping die comprises an upper die cover, a lower jacking die, a die removing layer, a punch, supporting arms, connecting rods, ejector pins and ejector assemblies. The upper die cover and the lower jacking die are arranged at the upper end and the lower end of the die removing layer. The punch is vertically arranged at the middle position of the upper die cover and downwards extends into the die removing layer. The supporting arms are arranged on the die removing layer and connected with the corresponding ejector assemblies through the corresponding connecting rods. The ejector assemblies are arranged in the lower jacking die. The ejector pins are vertically arranged in the die removing layer and downwards extend to beconnected with the corresponding ejector assemblies. In this way, the jacking type stamping die is provided with the ejector pins and the ejector assemblies, and the jacking type stamping die has theadvantages that the requirement for the tonnage of a machine tool is greatly lowered, the cost is saved, vibration is not large, noise is reduced, the die vibration is relatively small, no special sound is generated, the service life is prolonged, the quality of the die is improved, and the manpower and material resources are reduced.

Description

technical field [0001] The invention relates to the field of dies, in particular to a jack-up stamping die. Background technique [0002] Stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, called cold stamping die (commonly known as cold stamping die). Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts. [0003] Stamping die is an indispensable process equipment for stamping production, and it is a technology-intensive product. The quality, production efficiency and production cost of stamping parts are directly related to the design and manufacture of molds. [0004] At present, most stamping dies are a kind of die that directly breaks the material, including a die and a punch. The upper end of the die is a product ...

AI Technical Summary

Problems solved by technology

[0004] At present, most stamping dies are a kind of die that directly breaks the material, including a die and a punch. The upper end of the die is a product placement platform. Since all positions of the upper end surface of the die of the existing mold are at the same level, all the parts to be punched on the material are stressed at the same time during stamping, so that the tonnage of the punching machine is too large, and the vibration of the punching machine is too large , the noise is large, which seriously affects the hearing of the workers, is not good for the health of the workers, and can easily lead to the fatigue of the workers

In addition, the mold vibrates too much and has abnormal noise, which is easy to cause the punch and die to be bitten and damaged, which reduces the life of the mold
