PURPOSE:To manufacture the bent product excellent in shape precision by fixedly supporting the bent product and providing a shape correcting force applying device at a required part. CONSTITUTION:An outline of the shape is set with abutting metal tools 8, 9, 10 supporting bent parts 1a, 1b, 1c of a bent product 1, and the neighborhood of a straight part 15e is fixed by clamping while moving a tightening clamp piece 7b with respect to a fixed clamp piece 7a. When the bent product is fixed in such a way, an error of shape is caused on both ends, so the shape is corrected by driving and advancing or retreating rods of a pair of air cylinders 11a, 12a and applying force to the direction to be corrected. |
