Abstract

a. Procédé pour fabriquer par fluage sous pression un corps métallique creux de révolution. b. Procédé caractérisé en ce que l'épaulement interne et l'épaulement externe du corps metallique creux, sont obtenus par fluage sous pression dans un processus de travail unique, mais cependant dans une ou bien dans plusieurs étapes de formation, l'étape << formation de l'épaulement interne >> avec réduction simultanée du diamètre externe du corps métallique creux, se déroulant avant l'étape << formation de l'épaulement externe >>. c. L'invention s'applique notamment à la fabrication des cylindres de vérins hydrauliques.
