摘要： A method, and an apparatus, for operating a hydraulic shearing machine. For cutting a shearing-movement of at least one shear blade which is curved, starting from a starting-position under application of an overall actuating-force and for resetting of the shear blades which were moved for cutting to their starting-position after accomplishment of the shearing-movement, a reset-movement under application of an overall reset-force. The shearing-movement and the reset-movement are accomplished by a hydraulic actuating-mechanism comprising hydraulic cylinders, wherein the overall actuating-force and the overall reset-force being applied to the moved shear blades by at least one hydraulic cylinder of the actuating-mechanism. The magnitude of the overall actuating-force is adjustable by switching one or several hydraulic cylinders of the actuating-mechanism in and out of operation-mode. The method proposes that the positions of the curved shear blade are controlled by a control system by regulating the flow of hydraulic fluid to the hydraulic cylinders according to setpoints for a shear blade position versus time function and the overall actuating-force and overall reset-force requirements.

摘要： The invention relates to the design of multiple piece rolls, in particular backup rolls, for the use in metal rolling. The roll comprises a main part with a center bore for the removal of center defects or flaws arising from the manufacturing process, e.g., from casing or forging and at least an end part, whereas the end part has no center bore or a center bore with a diameter smaller than the bore diameter of the main part.
