AI Technical Summary

Technical Problem

Existing silicon steel sheet punching and shearing machines lack a fixing device after punching and shearing, which makes the silicon steel sheets easy to move, affecting the punching and shearing quality and efficiency.

Method used

A punching and shearing device for transformer core silicon steel sheets was designed, including a first conveyor belt, a punching and shearing table, a guide table, and a second conveyor belt. The device uses a first pressure roller, a second pressure roller, and a third pressure roller to stably transport and guide the silicon steel sheets. The spacing and elasticity of the pressure rollers are adjusted by a drive component to ensure the stability and accurate guidance of the silicon steel sheets at each stage.

Benefits of technology

It improves the punching and shearing quality and production efficiency of silicon steel sheets, ensures the stability and accurate guidance of silicon steel sheets in each conveying stage, and enhances the stability and efficiency of punching and shearing.
