Abstract

Procédé d'assemblage par poinçonnage de pièces métalliques, notamment par poinçonnage d'une pièce-poinçon dans une pièce de forme creuse à laquelle elle s'assemble ainsi. La pièce creuse étant calée dans une forme limitant sa déformation sous la pression de poinçonnage, la pièce-poinçon perfore et traverse une première paroi de la pièce creuse, puis, poursuivant sa pénétration, perfore et traverse une seconde paroi jusqu'à ce que la bordure de perforation de cette seconde paroi vienne s'encastrer par élasticité résiduelle de sertissage dans un logement de la surface de la pièce-poinçon. Assemblages de structures mécaniques notamment en construction automobile.
