Description

TECHNICAL FIELD

[0001] The utility model relates to profile processing technical field especially is related to a profile cold bending forming device. BACKGROUND

[0002] Cold bending forming is a plastic processing technology that continuously bends metal plates such as plates in the transverse direction by a plurality of forming rollers arranged in sequence to produce a profile with a specific cross section.

[0003] The current profile cold bending forming device still has the following shortcomings: 1. When multiple rollers are continuously formed, the profile is affected by the matching deviation of the transverse tensile stress and the longitudinal feeding speed, and is prone to asymmetric deformation. At the same time, the guiding mechanism lacking dynamic correction function is difficult to offset the lateral slip caused by the poor material ductility, ultimately causing the geometric tolerance of the formed cross section to be out of tolerance; 2. During the cold bending forming process, the open processing environment and the multi-pass rolling operation cause the metal surface to easily adsorb workshop dust or oil stains. Especially in equipment without a closed dust removal system, the metal particles generated by the high-speed friction between the roller and the profile mix with external pollutants to form an attached layer. Such surface contamination not only reduces the adhesion of the subsequent plating or coating, but also causes porosity defects in the welding process, directly affecting the corrosion resistance and structural strength of the profile.
