AI Technical Summary

Technical Problem

Existing room temperature cold forming processes result in high residual stress and significant springback within the material, making it difficult to maintain stable forming accuracy. Furthermore, these processes are time-consuming and labor-intensive, especially when the deformation is large, requiring an intermediate annealing process, which is cumbersome and inefficient.

Method used

The shell-type thermal forming fixture uses active heating to increase the plasticity and improve the fluidity of the workpiece material at high temperatures. By combining the forming module with the heat conduction module and the heating module, it achieves efficient and uniform forming operations, reduces residual stress and springback, and eliminates the need for expensive intermediate annealing processes.

Benefits of technology

It achieves higher and more stable shaping accuracy (such as 0.05mm flatness), improves shaping efficiency, reduces costs, has a compact structure, is easy to maintain, and ensures production continuity and safety.

Abstract

The utility model discloses a kind of shell thermal shaping frock, including shaping module, its working surface is matched with product appearance;Heat conduction module, it is attached to the non-working surface of the shaping module;And heating and fixed module, it is arranged on the heat conduction module, for providing heat source and conducting heat to the heat conduction module.The utility model increases the plasticity of the shaping workpiece material to be waited for under high temperature, fluidity becomes good, yield strength reduces by the mode of initiative heating, this makes shaping operation become more labor-saving, deformation more uniform, can significantly reduce residual stress and springback from root, to obtain higher and more stable shaping precision (such as reach 0.05mm flatness), and there is possibility to save expensive intermediate annealing process, improve efficiency, reduce cost.
