AI Technical Summary
Existing technologies are insufficient for effectively limiting and preventing deformation during the cutting of irregular metal parts, resulting in low cutting accuracy and deformation of irregular metal parts during the cutting process.
By employing a limit fixing mechanism and a liftable worktable mechanism, combined with the coordinated use of a motor, lead screw, cylinder, and pressure plate, it achieves precise positioning and support for irregular metal parts. Through the adjustment of the electric telescopic rod and the positioning table, the cutting thermal stress is dispersed to prevent deformation.
It improves the cutting accuracy of irregular metal parts and the convenience of the device, reduces deformation during the cutting process, and enhances the cutting effect and production efficiency.
