Claims

[Claims for Utility Model Registration] (1) A workpiece having a U-shaped cross section is placed on a fixed cutting blade provided on a fixed mold, and a movable mold is brought close to the fixed mold. After pressing the workpiece with a pad, a drive cam moves a slide cam provided on the movable mold, and the movable cutting blade provided on the slide cam and the fixed cutting blade cooperate to cut the workpiece. In a U-shaped workpiece cutting device for cutting a workpiece, the slide cam is disposed on the movable mold so as to be slidable in the horizontal direction, while the drive cam is provided on the fixed mold, and the drive cam is disposed on the fixed mold of the movable mold. A U-shaped workpiece cutting device characterized in that the movable cutting blade is set to move in a zigzag manner to cut the workpiece when approaching the workpiece. (2) A workpiece having a U-shaped cross section is placed on a fixed cutting blade provided on a fixed mold, and by bringing a movable mold close to the fixed mold, the workpiece is held down by a pad provided on the movable mold. After that, a slide cam provided on the movable mold is moved by a drive cam, and the movable cutting blade provided on the slide cam cooperates with the fixed cutting blade to move the workpiece in the moving direction of the movable mold. In the U-shaped workpiece cutting device for cutting diagonally to the workpiece, the slide cam is provided along the cutting surface, and is disposed on the movable mold so as to be slidable horizontally and vertically with respect to the workpiece cutting surface. On the other hand, the drive cam is set to move the movable cutting blade in a zigzag manner when the movable cutter approaches the fixed die, and is further configured to move the slide cam so that the slide cam moves along the cutting surface. A U-shaped workpiece cutting device, characterized in that a guide is provided for moving a movable mold in parallel with the workpiece cutting surface in a direction perpendicular to the workpiece cutting surface.
