Claims

[Scope of utility model registration request]

A circular surface plate, a guide ring disposed in the center of this surface plate, and a ring-shaped die disposed around this guide ring at an interval corresponding to at least the flange width of the workpiece. A die that is divided into a plurality of parts in the circumferential direction, is arranged so that it can slide in the radial direction using the key as a guide on the upper surface of the die holder, and the inner circumferential side of the die is formed in a shape that matches the workpiece. , a die receiving ring that surrounds these dies and is arranged on the surface plate at a predetermined distance from the periphery of the die; a die receiving ring corresponding to each of the dies and attached to the die receiving ring via an elastic body; A bolt that constantly pulls the plurality of dies toward the die receiving ring side slides into contact with the inner periphery of the die receiving ring from above, and simultaneously pulls each of the dies toward the inner periphery side against the elastic force of the elastic body. A movable first upper mold, which holds the first upper mold and is lowered at the same time as the first upper mold, and moves the upper part of the workpiece disposed around the outer periphery of the guide ring to the die. A cylindrical bellmouth curved mold with a flange, which is equipped with a second upper mold that can be formed into a predetermined shape by cooperating with the mold.
