PURPOSE:To easily replace a die, and to replace it automatically, by installing a slide roller to a die holer, in a bending device. CONSTITUTION:When a top force 10 to be used is selected, a rod of a die replacement device is fitted into a hook hole 5, and is pushed into the lengthwise direction. In this case, overhang parts of both sides of a slide plate 4 to which the top force 10 has been installed contact with a roller 6, and between the upper end of the slide plate 4 and the upper surface of a groove of a die holder 2, a space is generated. When the rod of the die replacement device is inserted into a prescribed position, it is returned to its original position. During this process, tapered head 16 remains raised, accordingly, a clamp head 31 is kept inward from the slide surface. When said operation is executed and a clamp command is given, the tapered head 16 goes down, and the slide plate 4 is fixed to the die holder 2. |
