Abstract

Dispositif d'entraînement auxiliaire agissant directement sur le coulisseau pendant l'exécution de la course à vide. Le vérin de manoeuvre est constitué d'un cylindre 2 fixé au bâti 1 de la presse, d'un piston 3 et de tiges 4, 5. La tige 4 porte le coulisseau 6 muni d'un outil inférieur 7, et l'outil supérieur correspondant 8 est fixé au bâti 1. L'ébauche 9 est façonnée pendant la course de travail effectuée dans le sens 10. Un bras en porte à faux 12, se déplaçant dans la fente 11 du bâti 1, porte une crémaillère 13 entraînée par le pignon 14 monté sur l'arbre moteur 15. Les chambres cylindriques 16 et 18 sont reliées par les tubulures 17, 19 comportant une soupape 20. Le fluide provient de la source 21.
