ABSTRACT:
A piercing punch, a piercing die and a swaging punch are displaced relative to each other to produce locking joints by a machine which uses cams, preferably in the form of pairs of mating, wedge-shaped blocks to produce the necessary reciprocating movements of one or more of the three tool elements. A suitable kinematic actuating device, preferably in the form of a toggle linkage reciprocates the third tool element.
The interaction of these elements is such that exceptionally favorable conditions for joint formation prevail.
