    摘要： The invention comprises an improved rethreading die, a method of making the die, and a method of rethreading an in situ stud member. The workpiece from which the die is formed has oppositely directed front and rear faces and laterally outwardly facing side surfaces about the periphery of the front and rear faces. Recesses are formed in said workpiece for receipt of a hinge and its retaining pins. The hinge and pins are fitted in the recesses in the workpiece. The hinge and pins are removed, and the workpiece is divided, generally transversely with respect to the front and rear faces, into a pair of die members. The hinge and pins are then replaced in their recesses in engagement with positioning reference surfaces formed by those recesses. The die members thus formed and hingedly connected each have a first end, the first ends being disposed generally adjacent each other to one side of an inner opening formed prior to splitting of the workpiece. The second ends of the two die members are disposed generally adjacent each other and spaced about the inner opening from the first ends. The hinge mechanism permits the second ends of the two die members to be moved toward and away from each other between an open position permitting passage of a stud between the second ends into the inner opening and a closed position permitting engagement of thread forming surfaces adjacent the opening with the stud. Thus, the die may be emplaced about an undamaged inboard portion of an in situ stud, external wrench surfaces on the die can be engaged with a retaining tool, and the die rotated with that tool in a direction to move it progressively outwardly along the stud and over damaged outboard threads.

    摘要翻译： 本发明包括一种改进的加工模具，一种制造模具的方法，以及一种重新布置原位螺柱部件的方法。 模具从其形成的工件具有相对的前后表面和围绕前表面和后表面的周边的横向向外的侧表面。 在所述工件中形成有用于接收铰链及其保持销的凹口。 铰链和销钉安装在工件的凹槽中。 铰链和销被移除，并且工件相对于前表面和后表面大致横向地分成一对模具构件。 然后铰链和销在其凹部中被替换成与由这些凹部形成的定位参考表面接合。 这样形成和铰接连接的模具部件具有第一端部，第一端部大致彼此相邻地设置在在分割工件之前形成的内部开口的一侧。 两个模具构件的第二端部大致彼此相邻地设置并且与第一端部的内部开口间隔开。 铰链机构允许两个模具构件的第二端在允许第二端之间的螺柱通过内部开口的打开位置之间彼此移动并远离彼此，并且闭合位置允许与相邻的螺纹形成表面接合 用螺柱打开。 因此，模具可以围绕原位螺柱的未损坏的内侧部分放置，模具上的外部扳手表面可以与保持工具接合，并且模具沿着该工具沿着螺柱逐渐向外移动的方向旋转， 并损坏外线。

    摘要： Disclosed are a structural member, such as a truss, and a method and apparatus for fabricating the same from flexible sheet material in compacted form. A plurality of generally tubular columns are progressively formed from the sheet material and deployed generally parallel to one another. Adjacent pairs of the columns are interconnected by respective side members, each of which is comprised of a strip of the sheet material. The sheet material is fastened together by self-attaching fasteners integrally formed from the sheet material of the columns and side members themselves.
