Abstract

L'invention concerne un procédé de fabrication d'une soupape de moteur creuse, l'état de surface d'une surface intérieure permettant de former un trou creux étant satisfaisant et le volume du trou creux pouvant être augmenté. Ce procédé de fabrication comporte une étape de forgeage (S3) destinée à obtenir un composant intermédiaire (7) doté d'une partie cylindrique (8B) et d'une partie en forme de demi-parapluie (9B) continue avec un côté d'extrémité d'arbre de la partie cylindrique par un processus de forgeage, une étape de traitement thermique (S4) destinée à traiter thermiquement le composant intermédiaire pour une durée de rétention de chauffage (t2) déterminée en fonction de l'épaisseur de paroi (t) de la partie cylindrique (8B) pour ramollir les composants intermédiaires, une étape de filage (S5) destinée à allonger la partie cylindrique du composant intermédiaire traité thermiquement dans la direction axiale par un processus de filage et une étape de striction (S6) destinée à former une partie arbre (2) et une partie en forme de parapluie (3) en réduisant le diamètre de la partie cylindrique allongée axialement par un processus d'étirage.
