Definitions

  • the invention relates to a multi-roll stand, in particular a six-high rolling stand, with a Axverschieb- and holding device for slidably mounted intermediate rolls and / or work rolls, in which the chocks in the rolling stand stand in the direction of rolling force are guided and in which the intermediate rolls and / or work rolls are displaced axially in opposite directions together with their respective chocks by acting in the direction of the roller axes hydraulic piston-cylinder units and both piston rods are articulated respectively by means of a main cross member.
  • each piston-cylinder unit On each side of a connecting traverse acts in each case a hinged or firmly bolted to the rolling mill piston-cylinder unit for moving an intermediate or work roll.
  • Each piston-cylinder unit is controlled by its own servo-control circuit.
  • the displacement paths of the piston-cylinder units are detected by odometer.
  • a malfunction of the travel sensors, the hydraulic valves or a loose contact on the control cables can cause the pistons of the displacement cylinders to move uncontrollably to different heights or in opposite directions.
  • the connecting beam can thereby be damaged and unusable.
  • the initially described multi-roll stand with a Axialverschiebe- and holding means for the intermediate rolls are provided, for example in the form of two axially outwardly projecting arms as pliers (DE 24 40 495 C3). At each of these arms, the extendable piston rod of a piston-cylinder unit is connected by means of a connecting member, wherein the two piston-cylinder units are arranged in the rolling stand laterally next to the respective chock.
  • Such constructions do without a main crossbar. However, they are not secured against the failure of a hydraulic or electrical malfunction.
  • a similar construction makes use of within the chock displaceable bearings for the roller and a sliding carriage which receives a coupling device for the pin. Here, too, engage parallel to the roll axis piston-cylinder units, in whose malfunction, the carriage can jam.
  • Another structure (EP 0 026 903) transmits the axial displacement force of the externally arranged, parallel piston-cylinder units via a main crossbar, on both sides parallel-acting holding plates and a piston-cylinder unit for releasing the holding plates when the roller unit to be removed should.
  • the third piston-cylinder unit has only one interchangeable function. Nevertheless, no measures for hydraulic or electrical malfunctions to protect the traverse are provided here.
  • a Axialverschiebe- and holding device for slidably mounted intermediate rolls of a multi-roll rolling mill is known (DE 31 45 134 C2), which generates high axial forces and can be solved for changing rolls quickly from the intermediate roll pin.
  • a thrust bearing block is guided by means of Parallellenkem on each carriage.
  • the coupling device is designed as a chuck for coupling with the intermediate roller pins. Since a traverse for the piston-cylinder units is also necessary here, there is also the risk of jamming a carriage.
  • the invention has for its object to lock the intermediate rollers and / or the work rolls in the trusses and the point of displacement of the shift so verlagem that by a hydraulic or electrical malfunction, the trusses can not be damaged.
  • the above object is achieved in that arranged on both sides of the roll chock moving beams are each mounted via a connecting beam in the rolling stand, that the connecting bars are hinged centrally on the main beam, the piston rods of the piston-cylinder units at the ends of the main beam are articulated and that each piston-cylinder unit by means of a displacement sensor is path-dependent controllable.
  • the main advantage arises from the structure in the main crosshead and the connecting beam, so that a tension of the main crossbar can not occur.
  • Another advantage is a safe shift function and also easy assembly and maintenance can be performed.
  • a locking block for the locking of the roller is arranged on the drive side between the displacement beam in the roll chock.
  • the roll chock be connected to the locking block by means of a Verspann element.
  • the holding forces can be applied and transferred so low that the connecting beam with the locking block by means of a centrally located in the interior of the connecting beam, axially effective clamping disc can be fixed.
  • the holding force is generated to the effect that the clamping disc is actuated by means of a hydraulically acting clamping drive.
  • This tensioning drive is particularly simple and effective due to its centric arrangement.
  • the extent of the displacement is calculated as the mean value of the displacement paths detected in two associated Weggebem.
  • the piston-cylinder units are then controlled so that the calculated average value of the displacement paths detected in two encoders can be entered into the respective independent control circuit of the piston-cylinder units.
  • each Piston-cylinder unit 5 is controlled path-dependent by means of a displacement sensor 10, as soon as a sliding movement is performed.
  • a locking block 8 for the locking of the rollers 11.
  • the roll chock 7 with the locking block 8 is connected by means of a Verspann-element 9.
  • the holding device is now designed such that the connecting beam 2 is fixed to the locking block 8 by means of a centrally arranged in the interior of the connecting beam 2, axially and / or radially effective clamping plate 12.
  • the clamping disk 12 can be actuated by means of a hydraulically acting tensioning drive 9a.
  • the extent of the displacement path 13 is calculated as the mean value of the displacement paths 13 detected in the two associated Weggebem 10.
  • the calculated mean value of the displacement paths 13 detected in the two Weggebem 10 is introduced into the respective independent control loop of the piston-cylinder units 5.
  • a turntable 14 of the Verspann drive 9a is rotatably mounted, which is rotatable back and forth.
  • the rotational movement is generated, for example, by a hydraulically, electrically and / or mechanically operating straight thrust engine 15, so that from the linear movement 16, the rotational movement 17 is generated in the respective direction indicated by an arrow.
  • the coaxially located under the tensioning drive 9a clamping plate 12 (Fig. 3) is open in the position shown, wherein the clamping plate 12 points with its longitudinal shape 12a upwards.
  • the locking block 8 is therefore axially free and the roller 11, for example an intermediate roller, can be pulled out axially to the operating side for the purpose of replacement.
  • the clamping plate 12 is placed transversely with its longitudinal shape 12a by means of the tensioning drive 9a and the locking block 8 can not be axially displaced, ie the shift bar 1a, the locking block 8, the connecting beam 2 with the main crossbar 4 form a rigid unit.
