Claims

[Scope of utility model registration request]

゛A device for flanging the end of a press work and cutting the edge of the flange, on which the press work can be placed, and a mold surface for flange forming on the side,
A lower mold having a cutting edge for edge cutting is provided at the lower corner of the mold surface for flange forming, and an upper mold that moves up and down in opposition to this lower mold,
A sliding punch is movably supported by an elastic member in a direction away from the flange forming mold surface of the lower die and having a flange forming mold surface and an edge cutting edge at an upper corner of the mold surface. Additionally, the lower die is provided with an inclined cam surface of the sliding punch that comes into contact with the inclined cam surface of the sliding punch after flange processing and communicates with the sliding punch for edge cutting.
