  • Patent number: 4974437
    Abstract: A strip mill has the strip deflectors, the strip guide tables, the spray devices for cooling the working rolls and the strip lifters all disposed in the region of the working rolls in a readily accessible structural unit which also forms the guide rails upon which the journal blocks for the working rolls are guided for withdrawal of the working rolls from the mill stand. The unit is connected with our integrated in the working roll bending blocks and parts of the unit are connected with the latter by an inclined groove and rib arrangement.

  • Patent number: 4781052
    Abstract: Actuator device for axially shifting rolls which can be powered rolls journaled by way of radial bearings in holding elements in a rolling mill frame, uses hydraulic cylinders. At the drive side, the journal portions of the working rolls are respectively stepped to provide a centering roll portion, onto which respectively, an axial bearing is mounted to be positively held in position. At the housing of this bearing is attached a hydraulic cylinder which carries out the adjustment/control operation. The respective locking after mounting a new roll, for example, is achieved by a spindle head which is slipped on and which transmits the motive power of a driving spindle by way of the locking function performed by this spindle.

  • Patent number: 4744235
    Abstract: The rolls of a rolling mill can be axially moved by way of an actuator device equipped with piston-and-cylinder units. The bearing blocks which receive the journal ends of the rolls to be moved are horizontally guided in separate guide bodies. The guide bodies, in turn can be shifted vertically in cylinder blocks arranged at the flanks of the windows of the respective base member, or in pressure plates associated with such cylinder blocks. The actuator device is characterized by a compact design which even during exchange of rolls is contained in the confines of the roll stand, and it can be easily coupled to the rolls to be moved. The guide bodies of at least one base member are formed with lateral projections at which are mounted the motive power providing hydraulic cylinders, and these are connected in such a way that the piston rods thereof point in the direction of the guide bodies.

  • Patent number: 4736609
    Abstract: The rolls of a rolling mill, especially the working rolls, are horizontally shifted by a compact adjusting device, with use being made, as required, of guide pieces. The device is readily arranged in cylinder blocks, and the movements of the device can be easily monitored, transmitted, and set. The predetermined motions are carried out in rigidly controlled manner and no elastic yielding is allowed because of pressure plates extending in the windows of the base frame members. The pressure plates can be horizontally aligned and they cooperate with the holding elements which are to be shifted. The pressure plates are supported by wedges which can be shifted horizontally and transversely with respect to the plane of the frame, by way of pressure posts which operatively engage the pressure plates.

  • Patent number: 4627261
    Abstract: A roll stand comprises a plurality of axially shiftable working rolls, each attached by supporting members axially slidably to a guide member which is movable vertically adjustably against the side of a cylinder block installed in the roll stand housing. Axially shifting hydraulic cylinders are provided to axially shift the working rolls by acting on the guide pieces. In particular a plurality of balancing hydraulic cylinders are installed in laterally projecting shoulders in the cylinder blocks behind each other in the axial shifting direction of the rolls and act on the working rolls to provide balancing and bending forces. In order to install only cylinder blocks of reduced size, the balancing hydraulic cylinders operating downwardly and the balancing hydraulic cylinders taken individually along the axial shifting direction project alternately downward and upward from the shoulder of the cylinder block associated with them and act on the guide pieces on which the working rolls are mounted.
