Abstract

Equipement et procédé de forgeage d’une denture d’engrenage sur un semi-produit Contenu de l’abrégé. L’invention concerne un équipement pour une machine de forgeage à chaud ou à mi-chaud (2) comportant:- un poinçon (4) fixe aménagé pour délimiter un siège de support du semi-produit (3) à forger;- un contre poinçon (5) monté mobile verticalement pour occuper une position inférieure pour laquelle le poinçon et le contre poinçon immobilisent le semi-produit,- un porte-outil (9) supportant un outillage d’extrusion (10) et étant aménagé pour recevoir la force verticale de compression du système d’application (2b) de la machine de forgeage pour extruder la denture du semi-produit lors du mouvement vertical de descente du système d’application (2b) de la force verticale de compression. Figure pour l’abrégé : Fig. 3
