1. A bending device having a bending mechanism for holding an elongated workpiece between a bending die and a clamping die revolvable around the bending die, and revolving the clamping die, to thereby bend the workpiece, the bending device comprising:
a fixing base on which the bending mechanism is mounted, and an articulated robot which is fixed to the fixing base, on which a chuck mechanism for holding the workpiece is mounted, and which moves the chuck mechanism, wherein
the articulated robot includes a plurality of parallel joints turning around mutually parallel axes,the chuck mechanism includes a chuck body and a turning member turnably supported by the chuck body,the chuck body includes a projecting portion,the turning member includes a pair of stopper members configured to hit the projecting portion, andthe chuck mechanism is configured to turn the turning member within a predetermined angle range, to thereby twist the workpiece held by the chuck mechanism around a longitudinal direction thereof within the angle range by making the projecting portion hit the pair of stopper members, and a control unit configured to further twist the workpiece by controlling the plurality of parallel joints of the articulated robot.
