Abstract:
1. A bending device comprising: a bending mechanism that clamps a longitudinal workpiece with a bending die and a clamping die that can be rotated around the bending die, and bends the workpiece by rotating the clamping die; 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 which moves the bending mechanism; and a control unit that controls the articulated robot, the bending mechanism and the chuck mechanism, wherein control performed by the control unit includes a bending/movement control in which the workpiece is moved by clamping the workpiece by the bending mechanism and moving the bending mechanism by the articulated robot, and the workpiece is bent by the bending mechanism while an entirety of the workpiece is being moved in a state of being separated from the chuck mechanism, and wherein the control unit includes a storage device to store data, for each type of the workpiece, indicating whether or not to perform the bending/movement control, and reads the data from the storage device and performs the bending/movement control in accordance with contents of the data.
