The invention relates to a bending device for the working rolls of a hot-rolling frame, comprising hydraulic piston cylinder units which transmit bending forces to the chucks of the working rolls, using guide elements. The invention aims to improve a bending device of this type, in such a way that the actuating forces which are to be generated are produced by a piston cylinder unit with dimensions small enough to be easily mounted into blocks which are to be provided in the windows of the frame, whilst retaining a free choice of the bearings for the support rolls. This is achieved by a double-action hydraulic piston cylinder unit (4, 5), provided for each block, whose two ends are connected to the guide elements (12, 13). Said guide elements (12, 13) encompass the free ends of the catches (20, 21) of the working-roll chucks (18, 19) on both sides by an axial displacement of the guide grooves (22, 23) which accommodate the working rolls (16, 17).
L'invention concerne un dispositif de pliage pour les cylindres de travail d'une cage de laminoir à chaud, comportant des ensembles pistons-cylindres hydrauliques qui transmettent des forces de pliage aux empoises des cylindres de travail par l'intermédiaire de guides. L'invention vise à améliorer le dispositif de pliage de telle manière que les puissances de réglage à produire soient fournies par un ensemble piston-cylindre, l'encombrement du dispositif étant suffisamment faible pour permettre un logement facile dans des blocs prévus dans la fenêtre de montant et assurer le libre choix des paliers des cylindres d'appui. A cet effet, on prévoit pour chaque bloc un ensemble piston-cylindre hydraulique (4, 5) à double action dont les deux extrémités sont reliées aux guides (12, 13) et les guides (12, 13) enveloppent, des deux côtés, les extrémités libres des nez (20, 21) des empoises (18, 19) des cylindres de travail avec des rainures de guidage (22, 23) autorisant un déplacement axial des cylindres de travail (16, 17).
