AI Technical Summary

⚠Technical Problem

Existing precision undercut stamping dies cannot be used for undercut stamping of metal flat panel shell products because the undercut is a rigid structure, while existing dies are only suitable for elastic products.

⚗Method used

A novel undercut stamping structure was designed, comprising an upper die and a lower die. The lower die includes a movable outer slider, a floating plate, an elastic element, a movable inner slider, and an elastic push rod assembly. Through the synergistic effect of these components, the internal undercut stamping of the metal flat panel shell product is achieved.

🎯Benefits of technology

It realizes the internal undercut stamping forming of hardware flat panel shell products. The structure design is novel and can be effectively applied to the internal undercut processing of hardware flat panel shell products.
