Cold roll forming device for metal plate machining and operation method of cold roll forming device

The invention belongs to the technical field of cold roll forming devices, and particularly relates to a cold roll forming device for metal plate machining and an operation method thereof.The cold roll forming device comprises a workbench and a supporting frame fixedly installed at the top of the workbench, a driving assembly is fixedly installed on the workbench, and a driving motor is fixedly installed on the driving assembly; and conveying rollers are sequentially arranged in the supporting frame, and extrusion assemblies corresponding to the conveying rollers are arranged in the supporting frame. According to the cold roll forming device for metal plate machining and the operation method of the cold roll forming device, the position of an inclined metal plate can be conveniently reset through an electromagnet and a supporting plate, the electromagnet works to generate magnetic force, then an iron block can be attracted to move, a concave frame can be driven to move when the iron block moves, and then a bu
