    • A shearing device for tendons such as wire, rope or cables. The device incorporates a shear block and clamping system having a first cylindrical block adapted for engaging an eccentric recess formed in a housing. Both the housing and the block are constructed with apertures therethrough adapted for receiving the tendon therein. Eccentric misalignment of the apertures is provided by relative rotation between the housing and the block to therein provide the shearing action. A clamp is disposed outwardly of the block for securing the tendon to be terminated. In this manner, a post-tension tendon of the type utilized in concrete construction or the like, can be safely terminated and controlled within a recessed region with efficiency and dimensional control.
    • 用于钢丝,绳索或电缆等钢筋的剪切装置。 该装置包括剪切块和夹紧系统,其具有适于接合形成在壳体中的偏心凹部的第一圆柱形块。 壳体和块都构造有穿过其中的孔,用于在其中接收腱。 通过壳体和块之间的相对旋转来提供孔的偏心不对准,从而提供剪切动作。 夹具设置在块的外侧,用于固定待终止的腱。 以这种方式,在混凝土结构等中使用的类型的后张力钢筋可以在效率和尺寸控制的情况下安全地终止并控制在凹陷区域内。

    • A method and apparatus for continuously forming pointed terminals from a length of wire. The length of wire is moved to a position where a portion of the wire is positioned between a pair of opposed swedges. The pair of swedges is closed to engage and deform the portion of wire. The wire is then moved to position the deformed portion of wire at a wire severing location and another portion of the wire is positioned between the pair of opposed swedges. The wire is twisted relative to the deformed portion to separate the portion of the wire ahead of the deformed portion to form a terminal. The pair of swedges are closed simultaneously with the twisting to deform the next portion of wire and these steps are repeated.
    • 一种用于从一定长度的线连续形成尖端的方法和装置。 线的长度移动到线的一部分位于一对相对的楔之间的位置。 这对楔形物被关闭以使线的一部分接合和变形。 然后将导线移动以将线的变形部分定位在断线位置处,并且线的另一部分位于一对相对的楔形之间。 线相对于变形部分扭曲,以将变形部分前面的线的部分分离以形成端子。 一对罗纹与扭转同时闭合,以使下一部分的线变形,并重复这些步骤。
