Abstract

L'invention concerne un rivet auto-poinçonneur (1) servant au rivetage auto-poinçonneur de deux pièces (7a, 7b) dans une direction de poinçonnage (R). Le rivet auto-poinçonneur présente une tête de rivet (2) et une tige de rivet (3), la tige de rivet (3) étant de forme cylindrique et présentant un diamètre de tige (D1). À une extrémité de la tige de rivet (3) opposée à la tête de rivet (2) est agencé un insert (6) de poinçonnage dont le diamètre de poinçonnage (D2) est au moins par endroits inférieur au diamètre (D1) de la tige de rivet (3). Le rivet auto-poinçonneur peut être introduit dans les deux pièces par percussion et/ou compression exercée sur la tête de rivet dans la direction de poinçonnage, la tige de rivet orientée vers l'avant, au moins une rainure (4) étant pratiquée sur la circonférence extérieure de la tige de rivet (3) et s'étendant sur plusieurs tours et entièrement autour de la tige de rivet (3) sous la forme d'un filetage (5). Le filetage (5) formant la ou les rainures (4) présente une inclinaison positive orientée dans la direction opposée à la direction de poinçonnage (R), l'introduction du rivet auto-poinçonneur (1) crée sur les deux pièces (7a, 7b) des protubérances qui forment un col fileté (11) dans les pièces (7a, 7b), et le rivet auto-poinçonneur (1) peut être dévissé des deux pièces (7a, 7b) le long du col fileté (11).
