Abstract
PURPOSE: To make a continuous process possible to manufacture the branch pipe, by successively applying the hydraulic bulging, the piercing, and the burring works to a pipe blank.
CONSTITUTION: The half die is parted to open the dies, and the pipe blank W, being bent by the second core metal 19 into a bow type, is inserted until its end strikes the second push ring 24. Next, the half die is tightened and the pipe blank W is fitted to the die hole 9. Then, the first core metal 10 is brought down by the piston 17 so as to fit the first core metal 10 into the pipe blank W; besides, the pusher 22 is brought down by the piston 23 and is thrusted against one end face of the pipe blank W. Hereupon, the inside of the pipe blank W is sealed to water tight condition by 0-rings 16, 21, respectively of the first and the second core metals 10, 19. At this stage, the pressure fluid is poured into the pipe blank W from the bulging pressure fluid feeder 14 through the hose 13, the pathway 12, and the piercing die hole 11 of the first core metal 10.
