Abstract
PURPOSE: To form the drawn part to a bulged square form by molding the pressing face of segmental dies in conformity with the shape of the pipe section to be formed and rotating the dies to drawn the pipe then revolving the pipe in synchronization with the dies.
CONSTITUTION: The working face 1a of segmental dies 1 is formed to the square section whose respective sides are bulged. The work pipe 9 is held in a chucking device 12 and is inserted into the dies 1. When a backer 3 and die 1 are revolved at a high speed, the backer 3 strikes the dies 1 at the time when it passes outside circumferential rollers 5 and the pipe 9 is drawn to the round form of the required diameter. Thence, when the chucking device 12 is revolved in synchronization with the dies 1, the dies 1 press the same position of the pipe 9 and the pipe 9 is drawn to the same shape as the working face 1a of the die 1. This method yields the design pipe 20 of the shape whose respective sections are bulged, such as square, through drawing.
