PROBLEM TO BE SOLVED: To provide a bending die in a press machine for maintaining the value as a product without damaging a workpiece by eliminating any slip between a bending blade and the workpiece when bending the workpiece by moving the bending blade while being abutted on the workpiece. SOLUTION: There is provided a rotary bending blade 1 with an inner bending center C of a workpiece W being a center of rotation. The rotary bending blade 1 has a substantially semi-cylindrical shape as a whole, a cutout part 22 is formed in a vicinity of a plate holder 6 at a lower end of a punch guide 5 of a punch die P. A guide 32 for guiding the rotary bending blade 1 is provided on a mounting plate 7. Both ends of the rotary bending blade 1 are rotatably supported by a supporting part 8 with the inner bending center C of the workpiece W being a center of rotation. COPYRIGHT: (C)2008,JPO&INPIT
