Abstract

L'invention concerne un dispositif de commande pour presse hydraulique. Pour corriger les inclinaisons ou flexions du sommier supérieur 30 de cette presse, qui est poussée vers le bas par une rangée de vérins 1, 2, 3, 4, 5, on prévoit un capteur de flèche 122 qui capte la flèche du sommier supérieur 30 et un dispositif de réglage hydraulique qui commande les vérins en fonction du signal du capteur de flèche 122. Un capteur 121 détecte les défauts de synchronisme des mouvements des deux extrémités du sommier 30 et le signal du captent de synchronisme 121 est comparé avec le signal du capteur de flèche 122. L invention s'applique à la fabrication de tubes fendus de grands diamètres à partir de tôles pliées en U.
