AI Technical Summary

Technical Problem

In the prior art, the core replacement process of sheet metal cold stamping molds requires removal and fixation of bolts, resulting in a long time for core replacement and the internal lubrication and cleaning of the mold separately, which consumes a lot of time and affects production efficiency.

Method used

A core replacement structure for cold stamping of sheet metal parts is designed, which is composed of a work box, placing panel, support rod, electric push rod and telescopic rod. The replacement is achieved through the clamping of steel belts and molds, combined with aeration parts and reverse parts, and is quickly cleaned and lubricated with air and liquid.

Benefits of technology

The convenience and speed of the core replacement process is achieved, the core replacement time is reduced, the production efficiency is improved, and the efficient operation of the mold is ensured through rapid cleaning and lubrication.

Abstract

The present invention discloses a core-changing structure for cold stamping of sheet metal parts, which relates to the technical field of cold stamping of sheet metal parts, including a working box, a placement panel, a support rod, an electric push rod, and a telescopic rod. The placement panel is fixedly installed on the surface of the working box, a reinforcing rib is fixedly installed on the top of the back of the working box, a support rod is fixedly installed on the back of the working box, an electric push rod is fixedly installed on the top of the support rod, and a telescopic rod is movably installed on the bottom of the electric push rod. The reinforcing rib and the outer wall of the placement panel are fixedly connected with a composite reinforcing plate by screws, and a core-changing part is arranged inside the working box. The core-changing structure for cold stamping of sheet metal parts can replace different molds during the rotation process through the core-changing part, and the mold is fixedly installed on the upper surface of the steel belt, and the telescopic rod and the mold are both clamped. Compared with the traditional core-changing fixation, this core-changing method is more convenient.
