AI Technical Summary

Technical Problem

Traditional roll forming equipment applies excessive force instantaneously, making it difficult to accurately control the bending angle, resulting in bending angle deviation and stress concentration, which affects the structural strength and dimensional accuracy of the parts.

Method used

The design employs a step-by-step roller assembly, including pre-bending of the first roller group and further bending of the second roller group. Combined with the pre-bending of the first and second forming rollers, and with the assistance of side pressure and extrusion roller groups, wear-resistant alloy steel material is used to achieve precise bending and uniform stress distribution.

Benefits of technology

It achieves precise bending and dimensional stability of workpieces, reduces stress concentration, improves the structural strength and dimensional accuracy of parts, reduces the risk of failure, and improves production efficiency, versatility, and durability of the equipment.
