Abstract (en)
[origin: US6244808B1] A punching, stamping rivet has a frustrum-shaped rivet head and a shank with a shank groove following thereafter. In order to create a riveted joint between two sheets, the sheets are punched through by the shank. A groove is subsequently stamped around the shank end in the lower sheet, thus pressing material of the lower sheet into the groove. In order to increase the strength of the riveted joint, the shank groove is concavely constructed, whereby the section of the groove, which section is adjacent the rivet head, extends at an angle with respect to the shank axis, which angle is less than an angle at which the section adjacent the shank end extends with respect to the shank axis.
