Claims

[Scope of utility model registration request]

A bending device that bends a plate material into a U-shaped cross section and forms a flange portion bent left and right in the U-shaped opening, the die having a recess corresponding to the U-shaped cross section. A lower die fixed to the upper die, a die part corresponding to the lower die guide, a punch attached to the upper die base of this die part and having a recess in the left and right directions in the base, and The punch is supported so as to be slidable in the direction and is always biased by an elastic member so that one end thereof fits into the punch recess, and the punch is attached to the lower part of the punch recess fitting part so that it does not protrude from the side of the punch when the face metal is inserted. A flange forming block is provided with a flange forming part that is recessed into the recess and has the height of the flange part, and the flange forming block is fixed to the upper part of the lower mold and comes into contact with an inclined cam provided on the flange forming block during the downward movement of the punch. A cam member for forming a flange portion by extracting the flange forming portion from a punch recess.
