Patent ID: 7975521

Claim:
A bending tool for bending press comprising two dies each of which includes: a die body, a blade provided at one end of the die body and having an outside edge, an inside edge, and a blade edge of a predetermined angle which angle is bisected by a vertical blade parting line, and a press bending block, the press bending block comprising a blade-side inner end edge and an outer edge opposite the blade-side inner end edge, the press bending block being provided at the end of the die body in a laterally separated relationship from the blade on an opposite side of the blade parting line, the bending block and the blade together defining a space therebetween extending along a direction substantially perpendicular to an edge surface of the blade, and wherein the dies oppose each other in a position such that the blade parting line of a first one of the dies is located at a position between the blade of a second one of the dies and a center of the a space between a blade and the bending block of the second one of the dies, wherein: an angle formed by the blade parting line and the outside edge of the blade on a side opposite to the bending block of each die is larger than an angle formed by the blade parting line and the inside edge of the blade; and the blade parting line of the first one of the dies is located at a position closer to the blade parting line of the second one of the dies than the blade parting line of the first one of the dies is to the blade-side inner end edge of the bending block of the second one of the dies.
