Claims

[Scope of utility model registration request]

an upper die body that is movable up and down; a lower die body that has a work stand on the lower side of the upper die body on which a bent edge provided at a substantially right angle to the edge of the workpiece is placed facing downward;
In a hemming device for hemming the bent edge by providing a passive cam adjacent to the work table so as to be rotatable in conjunction with the lowering movement of the upper mold body, a cradle is provided at a lower position adjacent to the work table. A slide plate having a slide curved surface for rotationally guiding the passive cam at a predetermined rotation radius is disposed on the pedestal, and the passive cam is provided with a slide plate having a slide curved surface for rotationally guiding the passive cam at a predetermined rotation radius. A configuration in which a curved blade is attached, which integrally includes a pre-blade portion that pre-bends the bent edge at a predetermined angle and a hem blade portion that is inherited by the pre-blade portion and permanently bends the bent edge. hemming device.
