AI Technical Summary

Technical Problem

The existing crank-slider based stamping mechanism has a relatively fixed structure, which makes it difficult to flexibly adjust the stamping stroke and make it impossible to adjust it according to the stamping depth required by the workpiece.

Method used

An adjustable stroke stamping mechanism based on a crank-slider was designed. By setting a telescopic mechanism between the shaft and the connecting shaft, the rotation of the shaft is converted into the linear motion of the adjusting frame by combining the cylinder and the transmission rod. The stable movement of the adjusting frame is ensured by the limiting structure, thereby realizing flexible adjustment of the stamping stroke.

Benefits of technology

It enables flexible adjustment of the stamping stroke according to the workpiece requirements, improves the accuracy and safety of the stamping process, enhances the ease of installation of stamping dies and the stability of the equipment, and reduces friction loss and equipment failure risk.
