摘要： A method and apparatus for interlocking at least one first tube (10) having a first diametric spacing between opposite points of the tube wall with a second tube (4) having a second diametric spacing between opposite points of the tube wall which is larger than the first diametric spacing. The first tube is loaded over a mandrel (50) having a punching end (54), and disposed into a holding block (30) having a holding cavity (32) conforming closely to the outer surface of the first tube. The second tube is disposed over a receiving block (40), which has a receiving cavity conforming closely to the outer surface of the first tube. The punching end of the mandrel is driven through the second tube and into the cavity in the receiving block, followed by the first tube. When the first tube reaches a lower limit of the receiving cavity, the first tube is compressed axially. The mandrel supports the interior of the first tube, the holding cavity prevents the trailing portion of the first tube from swelling outwardly, and the receiving cavity prevents the leading portion of the first tube from swelling outwardly. Thus, the portion of the first tube disposed inside the second tubular member swells under the axial compressive force, permanently interlocking the first tube with the second tube. The punching steps can be separated from the remaining steps of the method of the invention, or the second tube can be pre-punched. In further embodiments the method and apparatus of the invention can create a clinched interlock and/or a ‘T’-shaped interlocked assembly.

摘要翻译： 一种用于互锁的至少一个第一管（10）的第一管（10），其具有在管壁的相对点之间的第一直径间隔与第二管（4），所述第二管（4）在管壁的相对点之间具有大于 第一直径间距。 第一管被装载在具有冲孔端（54）的心轴（50）上，并且设置在具有与第一管的外表面紧密配合的保持腔（32）的保持块（30）中。 第二管设置在接收块（40）上，接收块（40）具有与第一管的外表面紧密相符的接收腔。 心轴的冲孔端被驱动通过第二管并进入接收块中的空腔中，随后是第一管。 当第一管到达接收腔的下限时，第一管被轴向压缩。 心轴支撑第一管的内部，保持腔防止第一管的后部向外膨胀，并且接收腔防止第一管的前导部向外膨胀。 因此，设置在第二管状构件内部的第一管的部分在轴向压缩力下膨胀，永久地将第一管与第二管互锁。 冲压步骤可以与本发明的方法的其余步骤分离，或者可以预冲压第二管。 在另外的实施例中，本发明的方法和装置可以产生一个夹紧的互锁和/或'T'形互锁组件。
