[0002] There are many steel pipe structural parts in the field of steel structure, for example, when producing and processing steel chimneys, these steel chimneys need to be coiled in the generation. When coiling, it is difficult to form the arc of the joint of the two ends of the steel plate. The original method mostly uses a pressure head tire, a pressure head plate, and then uses a press or a plate coiling machine to press the head when controlling the straight section of the steel plate. Since the press or the plate coiling machine cannot press the required arc, there is a long straight section at the joint of the two ends of the steel pipe after coiling, the ovality of the pipe opening is out of tolerance, and the coiling cannot be completed at one time. When the semi-finished product cylinder is taken out, there will be a large gap, and the semi-finished product cylinder needs to be transferred to a work station for welding and polishing, so that the production and processing of the steel chimney can be completed.
