Abstract

L'invention concerne un procédé et un dispositif de formage par extrusion fermée de pièces comprenant au moins deux dents ou branches. Le procédé consiste à pousser une tige de matériau métallique solide 8 au moyen d'un poinçon 5 dans un trou de guidage d'une matrice inférieure 1, sur laquelle est appuyée une matrice supérieure 2 comprenant une partie en saillie 2b et des parties creuses 2e s'étendant parallèlement à la direction de pression. L'invention concerne notamment le formage par extrusion des manchons des joints homocinétiques universels.
