Abstract
PURPOSE: To eliminate occurrences of wave-shaped wrinkles in the direction of axis at the outer circumferential surface of expanded part of pipes, by maintaining the front end of materials to be worked with an elastic body which is sufficiently small at the front end, so that the front end of materials to be worked does not touch a stool, in an elastoforming method in which a liquid of materials to be worked, such as pipe, etc., is charged.
CONSTITUTION: A pipe to be worked M is inserted into the opened part of a metallic mold 1, and an elastic body 5 which is formed in such a way that the diameter at the front end part 5a may become smaller than the inner diameter of the pipe M, is inserted into the pipe M. The pipe M is maintained so that its lower end will not touch a stool 2. This condition is maintained not only before the working is started, but also during the course of working. Therefore, even when the pipe M works downward together with the elastic body 5 at the initial stage of working, no compressive force is applied to the pipe M in the direction of axis. Moreover, even when the cross section of the elastic body 5 in the cavity of the expanded pipe is increased at the middle stage of working, the diameter of the front end part 5a will not exceed the inner diameter of pipe M. As a result, the lower end of the pipe M will not be pushed up by the front end part 5a.
