Then, the pressure die 14 is moved to hold the workpiece 1, and the bending die 6 and the clamping die 8 are rotated to bend the workpiece 1 into a predetermined shape. The wiper die 10 separates from or abuts against the work piece 1 while maintaining the parallel state with the work piece 1, so that the wiper die 10 contacts the outer circumference of the work piece 1 at the time of separation / contact. The wiper mold 10 does not scratch. Further, the drive source may be one of the cylinders 28, and the wiper mold 10 can be retracted with a simple configuration.
