AI Technical Summary

Technical Problem

Existing laser tube cutting fixtures are prone to causing tube wall dents or deformation when fixing square tubes, affecting the cutting quality. In addition, the high-temperature waste generated during the cutting process can easily stick to the tube, reducing the product yield. Meanwhile, metal shavings and dust may damage the cutting head.

Method used

Design a fixture assembly including a fixture block and a liquid supply system. By internally supporting square tubes and utilizing a coolant circulation system and flow channel structure, the assembly achieves stable fixation of the tubes and timely cooling and cleaning of high-temperature waste residue.

Benefits of technology

It improves the stability and quality of pipe cutting, avoids the adhesion of high-temperature waste residue, reduces maintenance costs, and increases product yield.
