    • 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。

    • A method of gripping a metal tubular member during a forming operation to resist damage to the gripped ends and reduce scrap, includes providing an outer tool having a recess structured to receive an end of the tubular member, inserting a resilient mandrel into the end of the tubular member and inserting the tubular member end into the recess. A compressive force is applied to the resilient member in a direction aligned generally axially of the tubular member to establish transverse expansion of the resilient member in order to clamp the tubular member end between the mandrel and the outer tool recess. The tube may be stretched beyond the yield point and formed while so clamped, after which the compressive force is removed so as to facilitate withdrawal of the formed tube. In one embodiment, the mandrel may consist of a composite which may have a lower durometer hardness inner portion and higher durometer hardness outer portions. In another embodiment, a substantially rigid mandrel is received within the tube end and an annular resilient sleeve is positioned on the outside of the tube end. The method may be used for a wide variety of purposes including forming structural vehicular members. Associated apparatus is provided.
    • 一种在成形操作期间夹持金属管状构件以抵抗对夹持端部的损坏并减少废料的方法,包括提供外部工具,所述外部工具具有构造成容纳管状构件的端部的凹部,将弹性心轴插入到所述端部中 管状构件并将管状构件端部插入凹部中。 压缩力沿着与管状构件的大致轴向对齐的方向施加到弹性构件,以建立弹性构件的横向膨胀,以便将管状构件端部夹在心轴和外部工具凹部之间。 管可以被拉伸超过屈服点并且在被夹紧的情况下形成,之后除去压缩力以便于形成的管的抽出。 在一个实施例中,心轴可以由可以具有较低的硬度计硬度内部部分和较高硬度的硬度外部部分的复合材料组成。 在另一个实施例中,基本上刚性的心轴被容纳在管端内,并且环形弹性套筒位于管端的外侧。 该方法可以用于各种目的,包括形成结构性车辆构件。 提供了相关设备。
