    • 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.
    • 提供了用于形成细长工件的装置和方法。 在第一实施例中,压机具有压头和活动的上压板,固定第一模具。 上引导构件设置在上压板上,用于随着压板的移动而使滑动构件各自运动。 下部引导元件,其以伸缩方式与上引导构件配合,固定到下压板。 第一模具与一对可旋转的第二模具构件配合,每个可旋转的第二模具构件具有可响应于滑动构件的运动而可旋转的。 在优选实施例中,固定到压板的上导向构件处于相对滑动接触并且将滑动构件与可旋转的第二模具连接。 在一个优选实施例中,细长金属工件可以通过在由压力机压头通过上压板施加到第一模具和第二模具构件的力的影响下弯曲而形成。 在第二实施例中,不使用压制机第一模具和相关联的导向构件,并且由第二模具构件实现成型。 提供相关方法。
