AI Technical Summary

Technical Problem

Existing sheet metal stamping fixtures are prone to causing the formed sheet metal parts to fit tightly against the lower die during the demolding process. Traditional manual removal of parts is inefficient and easily scratches the workpiece, making it unsuitable for mass production needs.

Method used

A sheet metal stamping fixture including a support plate, stamping components and a linkage demolding mechanism was designed. Automatic demolding is achieved by driving the upper and lower die holders together with a hydraulic cylinder. The linkage demolding mechanism is equipped with a return spring and a demolding plate. Combined with an adaptive holding and limiting component, the sheet metal parts are stably held by an elastic abutment rod and a pressure plate.

Benefits of technology

It achieves automated demolding, avoiding the problems of low efficiency and scratches caused by manual part removal, while ensuring the precision and appearance quality of sheet metal parts, and meeting the needs of mass production.

Abstract

The utility model relates to sheet metal processing technical field, and disclose a kind of sheet metal stamping tool, including bearing plate, still including stamping assembly and linkage demolding mechanism;Stamping assembly includes mounting bracket, upper die holder, lower die holder and oil cylinder, wherein mounting bracket provides installation base, lower die holder is used to place sheet metal part, and upper die holder and lower die holder cooperate to realize stamping, and oil cylinder drives upper die holder and lower die holder to close stamping.Oil cylinder output end is retracted after stamping, drives upper die holder to move up and away from lower die holder, and its top end is contacted with the top end of abutment frame, drives two groups of abutment frame synchronous up, drives support rod to move up and compresses reset spring, and demolding plate is stretched up and ejected from lower die holder, and realizes linkage automatic demolding, avoids artificial pickup efficiency low and scratch problem.
