cold roll forming machine

 

Cold bending roll forming machine is a new type of equipment for processing and manufacturing the tunnel supporting steel arch frame. It consists of base, mechanical transmission, roll forming system, hydraulic system, electrical control system and auxiliary system etc six parts. When working, the section steel to be cold-formed is pushed between the two active rollers by the door bracket of the auxiliary system, and the hydraulic system is activated to make the hydraulic cylinder push the dovetail groove and the cold-formed roller cold-formed steel, and take off it when reaching the arc required by the design.And the mechanical transmission system is started to make the active roller rotate and rely on friction to drive the section steel to move forward steadily and slowly, so as to realize continuous cold bending operation. After cold roll forming is done, closing the mechanical transmission system and starting the hydraulic system at the same time to retract the hydraulic cylinder. Placing the cold-formed steel on the door bracket of the auxiliary system. This cold bending operation ensures the strength of the material, improves the quality of the supporting steel arch, greatly improves the work efficiency, and the operation is simple and clear. Compared with the press, the cold bending roll forming machine has good working performance.
