形状修正装置。 A holding device that is inserted into the inside of a metal band from an opening at the edge of the metal band before welding, in a pipe making machine that continuously forms a metal band into a tubular shape and welds the edges to manufacture a welded pipe. A mandrel is attached to the tip of the shaft, and at the center of the mandrel, a central roller whose outer periphery rolls pressure against the inner bead of the welded pipe is rotatably supported, and at the front and back of the center roller, the outer periphery is on the opposite side of the inner bead. A modification of the inner bead shape of a welded pipe, characterized by arranging receiving rollers that make rolling contact and receiving the center roller, and also arranging ironing rolls for rolling the welded pipe above and below the outside of the rolling contact area of these receiving rollers. Device.
