Abstract
Procédé pour la fabrication d'une pièce par filage à la presse à partir d'une ébauche cylindrique. Les deux faces frontales de l'ébauche cylindrique 20 sont pressées de la même quantité en direction du milieu de l'ébauche 20 et la matiere constitutive de cette dernière est amenée à s'écouler symétriquement par rapport aux deux faces frontales à partir du milieu de l'ébauche cylindrique 20 radialement vers l'extérieur dans l'espace creux d'une matrice 14, 15. L'invention est applicable à la fabrication de diverses pièces, notamment de croisillons.Process for the manufacture of a part by press extrusion from a cylindrical blank. The two end faces of the cylindrical blank 20 are pressed in the same amount towards the middle of the blank 20 and the material constituting the latter is caused to flow symmetrically with respect to the two end faces from the middle of the cylindrical blank 20 radially outwards in the hollow space of a die 14, 15. The invention is applicable to the manufacture of various parts, in particular of cross members.
