Depending on the position of the fastening bolt of the metal fitting, it cannot be arranged at the intermediate position of the metal fitting because the small-sized metal mold deviates from the portion to be gripped. If the small mold is incorporated in the end, the layout of the mold may be changed, and furthermore, FIGS. 4 (a) and 4 (b)
As shown in the figure, the mold cannot be arranged symmetrically with respect to the center of the processing machine (in the figure, l 1図 l
2 , l 1 > l 2 ), and there is a problem that the bending reaction force at the time of processing the work is biased and the bending angle of the product becomes asymmetric (θL> θR in the figure).

スのとれた曲げ加工が可能である。In a bending machine such as a press brake,
When bending the work, if the left and right ends of the work are already bent, a conventional mold in which the left and right widths of the plate-shaped member (intermediate plate) 2 and the fastener 6 are the same. Although a gripping device may be used, for example, in bending of a long workpiece to the left and right which has not been machined at both ends, the fasteners 6 adjacent to each other have a minimum gap (gap) g and are almost continuous. (See FIGS. 3 and 5), the die 5 can be freely laid out and arranged in accordance with the bending line length of the work to be processed. Since the mold 5 can be mounted symmetrically with respect to the center of the machine body as a base point (in FIG. 5, l 1 = l 2 ), a bending reaction force is generated evenly in the work itself, and bending work in which the left-right balance is achieved is achieved. It is possible.
