Abstract
PURPOSE:To enable integral molding in cold working and to reduce the working time by deciding, first, the wall thickness of a cylinder part, then, the flange thickness of the other flange part, while integrally working the cylinder part and the flange part. CONSTITUTION:First, for example, a stainless pipe is cut to a prescribed length. Then, pipe 1 having a unit length is restricted by a diameter-reducing die 4 and is pressed by a press ram on a lower die 2 having the same diameter. Further, a diameter-reduced pipe 1 is restricted to a constraint die 7 and a lower die 8 having the same diameter and one end part being a flange part is pressed and spread by a flare punch 6. Furthermore, a flared flange part is restricted by a constraint die 11 and a lower die 12 and pressed by a press ram 10. The cylinder part and the flange part are integrally subjected to a primary molding by the above-mentioned stages. Next, the outer peripheral surface of the pipe having a pressed flange part is restricted by a constraint die 15 and a lower die 16 to make the thickness of the cylinder part thin according to a request. In this manner, since the thickness is allowed to move to the flange part and the cylinder part is set finally, cold working is easily performed.
