ABSTRACT:
A bending tool for a bending press comprising an upper die member detachably secured to a vertically reciprocable ram for bending a flat metal workpiece to a predetermined depth in a lower female bending die. The bottom surface of the female bending die cavity is formed by a plurality of flat headed pins in side by side slots or bores. The heads of the pins form the bottom flat surface of a longitudinal groove which forms the bottom die cavity surface. The vertical adjustment of the pins is provided by the interfitting combination of a left side wedge assembly, a middle wedge assembly and a right side wedge assembly. The interfitting prevents displacement of any one of the supporting assemblies for the pins to assure improved bending precision.
