PURPOSE:To shorten time for changing die and save labor by shifting racks of plural lines provided on one side of a bending machine and holding interchange dies of different length in plural plural steps, and making simultaneous shifting of dies on each rack to the working machine possible. CONSTITUTION:Plural lines of racks 17, 19 that hold interchange dies (top die 5, 15 etc.) of different length in plural steps are provided on one side of the bending machine 1 at right angles to the direction of working and shifting a plate material 3. The racks 17, 19 are raised and lowered along a guide rail 23 of the rack structure 21, and for instance as shown in the figure, it is possible to select combination of top dies 5A, 15A of the same length and position them simultaneously in a shifting device 37 for carrying in. Accordingly, these top dies can be shifted simultaneously to the working machine 1 by a die shifting device 87. |
