Abstract

L'invention concerne un rivet à poinçonnage/estampage présentant une tête de rivet (14), qui forme une extension (20) de type tête, en particulier en forme de cône tronqué, et une tige (15) qui est raccordée à la tête de rivet (14) et présente au moins une rainure de tige (16). Pour établir un assemblage par rivets entre au moins deux parties structurales adjacentes, la tige (15) traverse les parties structurales en formant un trou poinçonné, une rainure étant ensuite estampée autour de l'extrémité de tige sur la partie structurale située à cet endroit, de sorte que du matériau de la partie structurale située à cet endroit pénètre dans la ou les rainures de tige (16) sous déformation plastique, le rivet à poinçonnage/estampage étant fabriqué à l'aide d'au moins une opération de moulage par pression dans une technique de formage à froid.
