AI Technical Summary

Technical Problem

The existing side-assisted pushing structure of the pipe bending machine uses a hydraulic mechanism, which has low precision and causes errors in the bending angle.

Method used

It adopts a lead screw and gear structure. The first gear is driven to rotate by a motor, which drives the second gear and the rotating sleeve to move on the lead screw, so as to achieve precise position adjustment of the push rod and provide lateral thrust.

Benefits of technology

This improves the bending accuracy of the pipe bending machine, ensures accurate control of the push rod movement distance, and reduces bending angle errors.
