    • 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。

    • 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.

    • An integral structural element particularly well suited as a component of a body-in-white comprises an elongated hollow member with a first end and a second end opposite thereto. A first region, a second region, and a third region extend between a first end and a second end of the hollow member. A first flange extends substantially the length of the elongated hollow member. A second flange extends substantially the length of the elongated hollow member's first region. A first socket or connecting structure is adapted to receive therein a roof header and is disposed on the elongated hollow member between the first region and the second region. A second socket is adapted to receive therein a B-post disposed on the elongated hollow member between the second region and the third region. This integral structural element is a component of a motor vehicle's body-in-white.
