Functional element, method for fixing it in a sheet metal part, assembling element and swaging assembly

摘要

The invention concerns a functional element, in particular a bolt, consisting of a shank portion ( 14 ) and a head portion ( 16 ) designed to be assembled riveted with a plate element, in particular a sheet metal part. The invention is characterised in that the head portion ( 16 ) is hollow and has practically the same external diameter as the shank portion. When mounted, the hollow head portion ( 16 ) of the functional element ( 10 ) forms a riveting edge ( 37 ) on one side of the sheet metal part and an annular groove ( 52 ) on the other side of the sheet metal part, the annular groove ( 52 ) acting as a flange. The invention further concerns a method for fixing the functional element in a sheet metal part and the resulting assembling element ( 16 ), as well as a matrix and a swaging assembly.
