Abstract
A bending device that bends a workpiece is provided with a bending mechanism that bends the workpiece, a fixing table on which a chuck mechanism that grips the workpiece is mounted, an articulated robot to which the bending mechanism is attached, and a control unit that controls operations of the bending mechanism, the chuck mechanism, and the articulated robot. The control unit includes a first control unit that twists the bending mechanism around a longitudinal axis of the workpiece, and a second control unit that controls the articulated robot to twist the bending mechanism holding the workpiece around the longitudinal axis of the workpiece within a twisting angle range and then causes the first control unit to perform the twisting.
