たことを特徴とするヘミング加工機。 A lower mold having a tapered first guide surface and on which the flange portion of the plate-shaped workpiece is placed along the first guide surface, and a main bending mold that is fixed to a ram that moves up and down and performs bending of the flange portion. a blade, a bracket having a second guide surface inclined with respect to the moving direction of the bending blade and fixed to the ram, and a slider assembled to the bracket so as to be slidable along the second guide surface. a preliminary bending blade which is fixed to the lower end of the slider and which preliminarily bends the flange portion prior to bending by the main bending blade; a spring which urges the slider downward; and a spring which urges the slider downward. positioning means for regulating movement and positioning the preliminary bending blade directly below the main bending blade, and after the preliminary bending blade completes bending of the flange portion, the bending blade slides on the first guide surface. A hemming machine characterized by being retracted from directly below the main bending blade when it comes in contact with the main bending blade.
