AI Technical Summary

Technical Problem

In traditional fin edge cutting processes, material clogging and skipping are prone to occur during the feeding process, affecting the accuracy of subsequent processing and increasing the complexity of traditional molds.

Method used

By adding upper and lower slitting blades to the edge cutting die, edge cutting and slitting can be performed simultaneously. The sheet can be selectively cut into segments during the edge cutting action, and the stability of the sheet is ensured by independent stamping action and limiting structure.

Benefits of technology

It improved the quality of subsequent processing, reduced the impact on the mold, reduced the cost of mold modification, and ensured the stable delivery of the material sheets.
