Abstract

LA PRESENTE INVENTION CONCERNE UN PROCEDE D'ENTRAINEMENT DE MACHINES-OUTILS A PORTE-OUTIL A VA-ET-VIENT, EN PARTICULIER POUR LA DEFORMATION PLASTIQUE DES METAUX SELON LE PRINCIPE DES PRESSES A GENOUILLERE. PROCEDE CARACTERISE EN CE QU'UN ECOULEMENT HYDRAULIQUE AGISSANT DYNAMIQUEMENT ENGENDRE UN MOUVEMENT DE ROTATION DU VILEBREQUIN ET EN CE QUE CE MOUVEMENT EST TRANSMIS AUX ARTICULATIONS DE GENOUILLERE D'UN SYSTEME DE LEVIERS A GENOUILLERE ARTICULES DEUX A DEUX ET FORMANT DES QUADRILATERES FERMES ET EST TRANSFORME EN UN MOUVEMENT DE VA-ET-VIENT. L'INVENTION EST PLUS PARTICULIEREMENT APPLICABLE AUX MACHINES-OUTILS DU TYPE PRESSE.THE PRESENT INVENTION CONCERNS A PROCESS FOR DRIVING MACHINE-TOOLS WITH A BACK-AND-BACK TOOL HOLDER, IN PARTICULAR FOR THE PLASTIC DEFORMATION OF METALS ACCORDING TO THE PRINCIPLE OF KNEEL PRESSES. PROCESS CHARACTERIZED IN THAT A HYDRAULIC FLOW ACTING DYNAMICALLY GENERATES A ROTATIONAL MOVEMENT OF THE CRANKSHAFT AND IN THAT THIS MOVEMENT IS TRANSMITTED TO THE KNEE JOINTS OF A SYSTEM OF TWO BY TWO ARTICULATED KNEELING LEVERS AND IS TRANSFORMATED FASTENED IN A BACK-AND-BACK MOVEMENT. THE INVENTION IS MORE PARTICULARLY APPLICABLE TO MACHINE TOOLS OF THE PRESS TYPE.
