AI Technical Summary

Technical Problem

Existing methods for scribing sheet metal parts are cumbersome and highly repetitive, failing to meet the requirements of rapid manufacturing. Furthermore, traditional tools cannot guarantee the accuracy and applicability of scribing.

Method used

A rapid scribing tool was designed, comprising a scribing arm, an upper positioning arm, a lower positioning arm, a tightening screw, a washer, a nut, and a positioning foot. It achieves scribing in one go through a guide groove and gear meshing structure. Combined with the adjustment of the positioning foot, it ensures that the scribing pen makes perpendicular contact with the tooling and part surface, avoiding deviation.

Benefits of technology

It enables rapid and accurate scribing of sheet metal parts, shortens the manufacturing cycle, improves scribing accuracy and tool versatility, and reduces costs.
