Press-in element for pressing into a non-pierced or pierced component and also method for the manufacture of the press-in element
Abstract:
A press-in element for pressing into a non-pierced or pre-pierced component, in particular a sheet metal part is described. The press-in element has a head part having a ring surface confronting the component and a neck part which projects away from the ring surface, i.e. from the component contact side. The head part further has a ring-like projection surrounding the neck part with a radial spacing and projecting away from the ring surface and the neck part has a radially outwardly projecting ring bead, which can be formed as a continuous ring bead or as a ring bead interrupted at points, with the apex of the ring bead having an axial spacing from the ring surface which is larger than the axial spacing of the apex of the ring-like projection from the ring surface, which lies radially within this projection and together with it and the ring bead forms a pocket which receives material of the component.
