Insertion method of sheet metal parts functional elements, to the functional element, plunger components and devices assembly

摘要

Functional elements comprising, on the bolt in particular (57) shaft portion (16) head which is designed plate elements, to be riveted assembled with sheet metal parts, especially [Abstract] The present invention, and (14) . Head (16) is hollow, the invention is characterized in that it has an outer diameter roughly the same shaft portion. When mounted, the head of the hollow functional element (10) to (16), on one side of the sheet metal part on the other side of the sheet metal part the annular groove (52), rivet edge (37) has an annular groove (52) serves as a flange. Furthermore, construction elements obtained sheet metal parts, as a result not only in (16), the present invention relates to a method for the matrix, the swage assembly to fix the functional elements.
