とするエツジベント装置。 A base of the edge bend mechanism, a slide cam with an edge stamping die installed flush in the center of the base, and one end of the work protruding from the base on one side of the slide cam. A first reference plate to be held, a second reference plate protruding from the base on the other side, and a stopper pin which is biased and protruded from the base on the outside of the second reference plate, and the workpiece is moved from the base to the slide. and an auxiliary plate of the upper die mechanism held between the cam and the second reference plate, and the second reference plate is brought into contact with the middle part of the workpiece that has been pressed by the edge pressing die and bent at the first reference plate portion. The stopper pin is provided at a position where a workpiece held by the first reference plate is placed, and by the time the workpiece is pushed by the edge stamping die and comes into contact with the second reference plate, it is removed from the workpiece and the stopper pin is separated from the first reference plate. An edge vent device characterized in that it is provided at a position to prevent the other end of the workpiece, which is further bent using the second reference plate as a fulcrum, from returning.
