AI Technical Summary

Technical Problem

Existing seamless steel pipe multiple-length sawing technology suffers from low precision, low efficiency, and poor stability in commercial vehicle manufacturing. In particular, traditional mechanical positioning and photoelectric sensor positioning methods are insufficient in terms of positioning accuracy and stability, and cannot meet the high-precision sawing requirements of commercial vehicles.

Method used

Design a equidistant multiple-length cutting device for seamless steel pipes used in commercial vehicle manufacturing. The device adopts a slider and clamping system controlled by a servo motor and PLC, combined with limit sensors, to achieve automatic positioning and precise cutting of the workpiece. The slider is driven by the servo motor to move, and with the help of the clamping and cutting machine, fully automatic equidistant multiple-length cutting is achieved.

Benefits of technology

It achieves high-precision and efficient automatic cutting of seamless steel pipes, improves cutting accuracy and stability, meets the high-precision requirements of commercial vehicle manufacturing, reduces manual intervention and equipment wear, and improves production efficiency.
