Abstract
L'invention concerne le formage par déformation des métaux On impose un point de cessation de l'accélération du coulisseau à une vitesse prescrite assurant une énergie désirée du choc sur l'ébauche. Pendant le mouvement du coulisseau de la presse on détermine l'écart du point où est atteinte la vitesse prescrite du point d'interruption de l'accélération et, en partant de cet écart, on modifie la valeur des paramètres du mouvement du coulisseau. Application au forgeage ou à l'estampage
