    • A method and apparatus for coldworking holes using rotational mandrel. The apparatus uses a tubular seamless sleeve made of shape memory alloys having a superelasticity property, a mandrel having major and minor diameter portions, an end-cap to seat and restrain axial and rotational motion of said sleeve. The preferred coldworking operation includes the steps of placing the sleeve firmly between the end-cap and the adapting-spacer which are carried on a mandrel pulling means, passing forward the major diameter portion of the mandrel through the sleeve whose diameter is therefore elastically expanded and thereafter shrinks, inserting the sleeve together with the mandrel into said hole, placing the end-cap against the workpiece, retracting while rotating the mandrel backward through and out of the sleeve; thereby expanding the sleeve wall against the hole bore and exerting radial outward force on the sleeve which in turn transmits the coldworking force to the hole bore and plastically expand said hole; thereafter the sleeve diameter shrinking to a smaller size to ease the removal of the sleeve out of the hole. The sleeve is reusable due to the superelasticity property of shape memory alloys.
    • 用于使用旋转心轴对钻孔进行冷加工的方法和装置。 该装置使用由具有超弹性的形状记忆合金制成的管状无缝套管,具有主要和小直径部分的心轴,用于支撑和限制所述套筒的轴向和旋转运动的端盖。 优选的冷加工操作包括将套筒牢固地放置在末端盖和适配间隔件之间的步骤,承载在心轴拉动装置上,将心轴的大直径部分穿过其直径弹性膨胀的套筒, 然后收缩,将套筒与心轴一起插入到所述孔中,将端盖放置在工件上,在将心轴向后通过和离开套筒的同时回缩; 从而使套筒壁相对于孔孔膨胀并且在套筒上施加径向向外的力,其又将冷加工力传递到孔孔并塑性地膨胀所述孔; 此后套筒直径缩小到更小的尺寸以便于将套筒从孔中移出。 由于形状记忆合金的超弹性,套筒可重复使用。

    • A device for arranging, clamping or contracting a ring-shaped securing mechanism, including an open clamping ring (3) with a securing section (5, 7) at each end; and at least two ring-shaped clamping jaws (11) located inside the clamping ring. The clamping jaws rest against the clamping ring (12) with their outer edge (12) and together at least almost form a circular opening with their inner surface (19). The device also has at least one spring-type mechanism (15) being situated respectively between the laterally contiguous clamping jaws to drive them apart or to part the clamping ring in its non-clamped state, in the direction in which the ring opening diameter increases and to secure the clamping jaws in the clamping ring. The open clamping ring can be clamped in the direction in which the diameter decreases by means of a clamping mechanism with at least two engaging sections which are provide for engaging with the securing sections.
    • 一种用于布置,夹紧或收缩环形固定机构的装置,包括在每个端部具有固定部分(5,7)的打开的夹紧环(3); 以及位于夹紧环内的至少两个环形夹爪(11)。 夹紧爪以其外边缘(12)抵靠夹紧环(12)并且至少几乎与其内表面(19)形成一个圆形开口。 该装置还具有至少一个弹簧型机构(15),其分别位于横向相邻的夹爪之间,以驱动它们分开,或者使夹环在其非夹紧状态下沿环开口直径增加的方向 并将夹爪固定在夹紧环中。 打开的夹紧环可以通过具有至少两个接合部分的夹紧机构沿着直径减小的方向被夹紧,所述接合部分提供用于与固定部分接合。

    • A clamp for an inline connector having a male and a female component comprises a first sleeve having a peripheral portion defining an opening for receiving and holding the male or female component. A second sleeve is provided adjacent the first sleeve and has an opening therein which is adjacent the opening in the first sleeve. A handle having a first end is pivotally connected to the first sleeve for rotation about the pivotal connection. A bracket is pivotally connected to the second sleeve member at one end thereof and pivotally connected to the handle at another end thereof. Rotation of the handle about its pivotal connection to the first sleeve moves the first sleeve and the second sleeve relative to each other between a first position where the first sleeve and the second sleeve are closer to each other and a second position where the first sleeve and the second sleeve are further apart from each other.
