Claims

[Claims for Utility Model Registration] 1. A blade made of a mesh-shaped cylindrical body fitted onto the outer periphery of a bellows-shaped flexible pipe so that the end thereof can be brought into contact with the outer periphery of the end of the flexible pipe. A pipe forming device for drawing forming, which can be freely opened and closed between a closed position where the blade end is pressed against the outer periphery of the end of the flexible pipe and a retracted position where the blade end is retracted in a substantially radial direction from the closed position. a plurality of chucks which are pivotally supported to the molding apparatus main body and whose inner peripheral surfaces form a substantially cylindrical shape in a closed state; an opening/closing mechanism that operates to open and close the chucks; A pipe forming device comprising: a fluid cylinder for driving an operating mechanism. 2. Each of the chucks is composed of a swinging arm that is swingably supported on the molding device main body, and a chuck main body that is supported with respect to the swinging arm so that its position can be adjusted in the radial direction. The pipe forming apparatus according to claim 1, characterized in that: 3. Moderation forming portions are formed on the inner circumferential surface of each of the chuck bodies for forming inward bending moderations on the inner and outer end sides of the drawn portion at the end of the blade. The pipe forming apparatus according to claim 2.
