Claims

[Scope of utility model registration request]

A pre-blade member having a pre-blade portion at a predetermined angle at its tip bends the flange at a predetermined angle by pivoting in an arc from diagonally above the flange provided in a rising shape on the edge of the workpiece placed on the lower die. The hemming processing device performs hemming processing by hemming the hemming processing, and the hemming processing device is provided with a slide body movable up and down above the lower die, a hem blade member for pressing the flange is vertically disposed on the lower surface of the slide body, and On one side of the slide body, an operating arm with a plate cam attached to the lower end that operates the pre-bracket with the pre-blade member attached thereto is vertically disposed, and the lower die fixing bracket to which the lower die is attached has a pre-bracket with the pre-bracket attached thereto. A hemming processing device characterized in that the center of rotation is movably provided to change the approach angle of the pre-blade portion with respect to the flange.
