AI Technical Summary

Technical Problem

In existing corrugated spring production, there are issues such as axial non-uniform stretching and waveform sagging caused by gravity, elastic rebound after molding leading to data positioning failure, and the inability of traditional homogenization annealing processes to simultaneously eliminate high-stress areas and protect low-stress areas from overheating.

Method used

A horizontal processing control system is adopted, including a horizontal bearing and transfer platform, a multi-axis linkage forming mechanism, a multi-dimensional online sensing system and a laser processing unit. Through discrete strain energy calculation and elastic reconstruction module, precise data mapping and differentiated annealing are achieved, and a laser annealing strategy with dual modulation of spatial path density and energy intensity is utilized.

Benefits of technology

It achieves precise matching of geometric stability and data for corrugated springs, eliminates elastic rebound error, completes single-stage differentiated annealing, improves processing accuracy and efficiency, shortens the process chain, and reduces energy consumption.
