A rolling device capable of applying horizontal vibration for metal clad plates includes two symmetrically arranged support frames, an upper roller and a lower roller both of which are provided between the two support frames and parallel to each other, four bearing seats which are fixed with two ends of the upper roller and two ends of the lower roller respectively, and four horizontal vibration apparatuses which are provided outside the four bearing seats respectively for driving the upper roller and the lower roller to horizontally vibrate. Every horizontal vibration apparatus includes an exciting hydraulic cylinder and a damper. One end of the exciting hydraulic cylinder and one end of the damper are fixedly connected with two sides of one of the four bearing seats respectively. Every horizontal vibration apparatus is provided outside one of the four bearing seats.

A rolling mill for solid elongated products, defining a rolling axis, including first and second rolling stations. Each station includes a load-bearing structure, a removable roll-holder cartridge with three rolling rolls movable radially and rotating around three equally spaced axes of rotation, and a roll having a vertical rotational axis. Three actuators mount on the load-bearing structure; three gear motor groups connect to the rolls by single extensions. The position of the second station rolls is rotated 60° from the first stations. The rolls with a vertical axis of the first and second stations are arranged on opposite sides of the rolling axis. All rolling stations allow lateral extraction of roll-holder cartridges from the same side of the rolling mill. The stations on the cartridge extraction side have actuators movable relative to the load-bearing structure. The stations with vertical rolls arranged on the opposite side have fixed actuators.

A rolling apparatus, including a stand, at least two rolls, which are attached to the stand by chocks and are displaceable in relation to one another in the axial direction, and at least one axial displacing device, which is assigned to a chock of at least one of the rolls and can act on this chock. The axial displacing device has a fixed block, at least one displaceable bending block and at least one displacing cylinder, which is assigned to the bending block and by which the bending block can be displaced in relation to the fixed block. The fixed block is of a multipart form.

A device for adjusting an object, for example a roll in a roll stand including a rotatably mounted pressure spindle and a torque motor having a stator and a rotor for rotationally driving the pressure spindle. In addition, the device includes a fixedly arranged pressure nut, which is engaged with the pressure spindle in a rotationally coupled manner via a thread to generate an axial movement of the pressure spindle in case of its rotation. Due to the axial movement generated in this way, the device can generate an axial adjustment force and transmit it to the object to be adjusted.
