A disc is welded on the upper die of the die, and the disc is drilled and tapped for connection with the oil jack of the double-head beveling machine. Three pressing piece baffles are welded on the upper template according to the curvature radius of the bending pipe. Similarly, three baffles are welded on the bottom die according to the curvature radius of the bending pipe, and the bottom die is fixed on the processing platform of the beveling machine with bolts.
