Abstract:
PROBLEM TO BE SOLVED: To provide a plate working machine with a bending function for bending a bend piece having two or more bends, and performing the bending different in bending direction, bending size, bending angle or the like by a same die.
SOLUTION: An upper die 21 and a lower die 22 to hold and fix a plate W are positioned. An upper side bend die 23 and a lower side bend die 24 are provided in an elevating/lowering manner on side surfaces of the upper die 21 and the lower die 22. The upper side bend die 23 and the lower side bend die 24 bend a plate piece Wa of the plate held by the upper and lower dies 21 and 22 by the elevating/lowering operation with respect to the upper and lower side bend dies 23 and 24.
