Abstract

Procédé et dispositif pour le formage à chaud d'une tête de soupape par écrasement d'une tige d'acier. Une tige 14 est fixée dans une pince 13 vis-à-vis d'une enclume 3. Un bâti mobile 37 porte un inducteur 51 entourant la tige. On applique un effort d'écrasement sur la tige pour provoquer la formation d'un renflement 57. Pendant la descente de la tige, on fait remonter l'inducteur pour que la distance d entre l'inducteur et le renflement reste égale au jeu radical entre la tige et l'inducteur. Application au formage à chaud de solides pleins à profil en champignons, en particulier au formage de têtes de soupapes.
