ABSTRACT:
Apparatus and a method for forming an elongated workpiece are provided. In a first embodiment, a press has a ram and movable upper platen to which is secured a first die. Upper guide members are provided on the upper platen for movement of slide members on each responsive to movement of the platen. Lower guide elements, which cooperate in a telescoping manner with upper guide members, are secured to a lower platen. The first die cooperates with a pair of rotatable second die members which are provided with each being rotatable responsive to movement of a slide member. In a preferred embodiment, the upper guide members secured to the platens are in relative sliding contact and links connect the slide members with the rotatable second dies. In a preferred embodiment, the elongated metal workpiece may be formed by bending under the influence of the forces applied to the first die and second die members through the upper platen by the press ram. In a second embodiment, the press first die and associated guide members are not employed and forming is effected by the second die members. Associated methods are provided.
