Abstract (en)
The bending device is adapted to bending of a longitudinal workpiece (1). The device comprises a bending die (6) that has an outer shape corresponding to the bending shape, a clamping die (50,52,54) that clamps the workpiece with the bending die, and a rotation mechanism (12,30) that rotates the bending die and the clamping die to a predetermined bending direction while the workpiece is being clamped between the bending die and the clamping die. The rotation mechanism is provided with a selection mechanism (30) that allows switching between a first rotation mode in which the bending die and the clamping die are rotated in a body and a second rotation mode in which one of the bending die and the clamping die is rotated independently of the other die. <IMAGE>
