Abstract

L'invention concerne un procédé et un appareil de réglage de la course d'un coulisseau de presse. 'Pour régler la course du coulisseau, l'outil mobile et l'outil fixe sont amenés en contact avec une pression prédéterminée de manière à fixer un point de mesure initiale qui tient compte des déformations élastiques. La limite supérieure de la course du coulisseau est ensuite fixée à partir de ce point de mesure initiale au moyen d'une butée mobile sur laquelle vient s'appuyer un poussoir qui ouvre un clapet. La butée mobile peut être commandée manuellement ou au moyen d'un dispositif de commande numérique. L'invention s'applique notamment à une presse-plieuse hydraulique.
