Abstract

La machine selon l'invention se distingue par un rotor 14 comportant des poches 18, chacune contenant une matrice 20 et un support de matrice 22 pour recevoir la pièce 24 devant être mise en forme de façon que, du fait de la rotation du rotor dans une chambre de chauffage, la pièce soit mise en forme par fluage de la pièce portée à la température de fluage sans qu'il soit nécessaire d'utiliser une seconde matrice complémentaire pour exercer une pression Le procédé selon l'invention convient en particulier pour la mise en forme définitive des ailettes pour les moteurs à turbines à gaz.
