Abstract

L'invention concerne un dispositif d'accouplement pour un laminoir à profiler les feuillards à froid, conçu de sorte qu'une cage intermédiaire puisse coulisser sur une base commune et soit accouplée à un arbre à réglage à action unique assurant simultanément les changements de positionnement requis en fonction de la régulation des forces de pression des cages de laminoir. Des accouplements (21, 22) raccordés à un système d'entraînement par des joints universels souples sont montés sur des supports d'accouplement (14, 15) prévus sur des guides linéaires coulissant verticalement de sorte qu'ils puissent être déplacés avec précision dans le sens vertical et horizontal, une cage intermédiaire (10) supportant ces pièces coulissant sur la base commune (1) permettant aux supports d'accouplement (14, 15), lorsqu'ils sont relevés pour être descendus, d'être arrêtés par des guides de centrage automatiques (14d, 15d). Ainsi, les accouplements (21, 22) font face aux extrémités des arbres de guidage (21, 32), ce qui permet d'accoupler ces derniers auxdits arbres de guidage en une seule action, la régulation en hauteur s'effectuant automatiquement sans qu'il soit nécessaire de lire et d'ajuster les niveaux des accouplements, et de réguler librement les forces de laminage au cours d'une opération de profilage puisque les accouplements sont maintenus libres en position verticale.
