  • Patent number: 10876565
    Abstract: A self-piercing rivet for producing a joining connection between at least two components, which comprises the following features: a rivet head and a rivet shank having a central shank bore, wherein the rivet shank comprises a cylindrical shank outer surface and a shank inner surface limiting the central shank bore, and wherein the shank outer surface and the shank inner surface are connected at the axial end of the rivet shank facing away from the rivet head by a flat shank end face and a shank end radius. The shank end radius transitions tangentially into the shank inner surface and the flat shank end face is connected to the shank outer surface by a cutting edge.

  • Patent number: 9968987
    Abstract: The present disclosure provides an adjustment aid for a joining device having a punch and a counter-tool which can be oriented coaxially to one another and can be moved axially towards each other for a joining movement relative to one another. Furthermore, the present disclosure provides a method for adjusting a joining device with a punch and counter-tool. A grid marking is embossed in a reshaped test part with the assistance of an embossable grid marking on a punch surface or on a counter surface of the counter-tool. This grid marking is evaluable in comparison to the discernible impressions of the punch surface and counter surface of the counter-tool.
