Abstract

L'invention concerne un procédé permettant de produire une pièce tubulaire, en particulier une tige de piston d'amortisseur. La première étape de ce procédé consiste à réduire une première zone partielle (3a) d'une pièce de départ tubulaire (3) au moyen d'une opération de formage radial pour diminuer les dimensions de son diamètre extérieur, puis à former une zone de transition (3c) qui s'étend transversalement à l'axe longitudinal (A) de la pièce de départ tubulaire (3) et relie la première zone partielle (3a) de la pièce de départ (3) présentant un diamètre extérieur réduit à une deuxième zone partielle (3b) non réduite, adjacente à ladite zone de transition (3c). Selon l'invention, la deuxième étape subséquente dudit procédé consiste à aplatir ladite zone de transition (3c) de la pièce de départ (3) au moyen d'une opération de formage pour conférer à la pièce (1) une épaule (2) présentant une angle sensiblement droit.
