Abstract
L'invention concerne l'usinage des métaux par déformation. Le procédé faisant l'objet de l'invention est caractérisé notamment en ce que le bout de l'ébauche tubulaire 2 chauffé jusqu'à la température de forgeage est rétreint jusqu'à obtention d'une portion cylindrique de diamètre égal à celui de la sphère à obtenir, puis, sur la partie rétreinte de l'ébauche tubulaire, on façonne par génération un bout hémisphérique étanche, après quoi on façonne par génération un étranglement jusqu'à obtention d'une sphère 6. L'invention s'applique notamment à la fabrication de la rotule du piston-plongeur d'un basculeur hydraulique de camion-benne, des soutènements hydrauliques, de diverses articulations pour les structures métalliques, des organes télescopiques articulés.
