Claims

[Scope of utility model registration request]

a fixed support mold for supplying a plate material whose edges are bent at right angles, a first movable frame mold surrounding the outer periphery of the fixed support mold, and a pressing mold corresponding to the bearing surface of the fixed support mold;
a second movable frame mold surrounding the striking mold;
A first spring is applied to the movable frame mold to protrude from the support surface of the fixed support mold to a height that surrounds the right angle bend of the plate material, and a second movable frame mold is used to partially bend the right angle bend of the edge of the plate material. A stepped portion is formed with a sliding mold having an approximately arc-shaped cross section that protrudes from the inner periphery of the second movable frame mold, and the pressing mold has a step portion provided with a sliding mold having a substantially arcuate cross section, and the inner periphery from the second movable frame mold at the edge of the plate material that slides on the sliding mold. Hemming characterized in that a pressing surface is provided for pressing a part of the right-angled bend protruding from the hemming die, and a second spring having a stronger spring elasticity than the elasticity of the first spring is hung from the pressing mold to the second movable frame mold.
