Claims

[Scope of utility model registration request]

A cross section in which a flange part that stands up approximately at right angles from the periphery of a plate-shaped work body is formed such that the tip of the flange part becomes a flat part that overlaps the upper surface of the periphery part of the work body, and the base of the flange part bulges upward. A hemming tool for bending to form a substantially semicircular beaded edge, the hemming tool comprising: a support base having a receiving surface capable of supporting the lower surface of the peripheral edge of the workpiece body; and a support base that is movably supported on the support base. It consists of a mold that faces the receiving surface with a gap therebetween, and a drive mechanism for vertically vibrating the mold with respect to the support base. When the support base is moved along the peripheral edge of the workpiece body while the mold is being inserted and the mold is being vibrated up and down, the flange portion is gradually rounded from its tip edge and reversed, thereby forming the bead edge. a first molding surface for molding the part; and a tip part of the flange part that protrudes from the first molding surface and extends downward in the process of molding the bead part by this first molding surface, in cooperation with the receiving surface. a second molding surface for molding the flat part by gradually bending it along the receiving surface; the flat part molded by the second molding surface; and the peripheral edge of the work body. A hemming tool, characterized in that a third molding surface that can be pressed between the hemming surface and the receiving surface is formed.
