AI Technical Summary

Technical Problem

In the processing of aluminum composite panels, the existing technology of thickening the entire panel before cutting results in serious material waste, high production costs, uneven forming, and low material utilization.

Method used

A multi-station continuous roll forming device is adopted. Through multi-pass progressive roll forming and multi-dimensional collaborative pressure structure, combined with the principle of constant volume, the local thickening of aluminum composite plate and directional material flow are achieved. The multiple forming stations and roller components of the multi-station continuous roll forming device are used to apply precise pressure to ensure that the material flows and accumulates in a directional manner under radial and axial pressure.

Benefits of technology

It significantly reduces material waste, improves material utilization, enhances forming accuracy and product strength, reduces production costs, and meets the needs of high-end fields such as aerospace.
