Definitions

  • the invention relates to a device for the axial displacement of rolls in the stand of a rolling mill according to the preamble of claim 1; See GB-A 2 024 454.
  • axial displacements of the rolls, especially the work rolls are necessary . Therefore, as can be seen, for example, from DE-OS 35 21 180, a device for the axial displacement of rolls in roll stands has been designed, in which the rolls are held in special chocks via their radial and axial bearings, which in turn are held in the roll stands of the rolling stand arranged sliding guides and sliding carriages are slidably guided.
  • the chocks hydraulic piston-cylinder units articulated, which are attached to the outside of the roll stand.
  • FIG. 4 shows that the bearing chock is fixed in the frame and the inner bearing ring of the radial bearing, which is designed as a roller bearing and is attached to the bearing journal of the roller, is axially movable relative to the outer bearing ring of the radial bearing or vice versa.
  • the thrust bearing is very complicated with a large number of individual actuators arranged within its housing, which leads to the fact that these, including the integrated displacement sensors, are extremely difficult to access and difficult to maintain.
  • the object of the invention is to provide a device for the axial displacement of rolls in a stand of a rolling mill, which is free from these known disadvantages mentioned above and is particularly characterized by its very simple construction and easy access to the hydraulic and mechanical components.
  • the axial forces to be applied by the displacement system for axially displacing the roller can therefore be kept lower in the bearing system on which the invention is based in comparison with roller displacement devices with axially displaceable chocks, and energy and costs can thereby be saved, in particular if, as in the arrangement on which the invention is based, the displacement system as a hydraulic pressure system in Thrust bearing is integrated.
  • the hydraulic pressure system integrated in the axial bearing consists of a double-acting piston-cylinder unit, the outer bearing ring of the axial bearing is designed as a piston and the bearing housing surrounding it is designed as a cylinder.
  • the outer bearing ring designed as a piston and the bearing housing of the axial bearing designed as a cylinder are made in several parts. In this way, the maintenance and replacement of the bearing or the hydraulic pressure system or parts thereof considerably relieved.
  • the radial bearings are, according to a further advantageous embodiment of the invention, with several, in rows in the axial direction at a distance bearing bodies arranged from each other. It is also particularly expedient to use a cylindrical roller bearing or a radial bearing designed as a needle roller bearing.
  • the drawing shows a section of a roller (1) of a rolling mill with a bearing journal (2) which is tapered in a step-like manner at the left end and is mounted in a radial bearing (3) and an axial bearing (4) shown in longitudinal section.
  • the right end of the roller (1) which is not shown in the drawing, is provided with a single-stage bearing journal which is mounted in a radial bearing of the same design as the radial bearing (3).
  • These radial bearings (3) consist of an inner, relatively long, attached to the bearing journal (2) trained bearing ring (5) and two outer bearing rings (7, 8) arranged in the stand (6) of the rolling mill and from the intermediate bearing bodies (9) arranged in four rows at a distance from one another.
  • This inventive design of the radial bearing (3) very advantageously allows an axial displacement (arrows 10) of the roller (1) together with the inner bearing ring (5) relative to the outer, two-part bearing ring (7, 8) without it to the undesirably disadvantageous, energy-consuming sliding friction between the bearing rings (5) and (7, 8), since the axial movement of the inner bearing ring (5) relative to the outer bearing ring (7, 8) is absorbed by the bearing bodies (9) and into one Rolling motion is converted from very little friction.
  • the radial bearings (3) are expediently designed as cylindrical roller bearings in order to be able to reliably absorb and compensate for the high loads occurring on the rollers during operation of the rolling mill.
  • other roller bearings such as needle roller bearings, barrel roller bearings, etc. in a single or multi-row arrangement can also advantageously be used as radial bearings.
  • the axial bearing (4) with integrated hydraulic bearings which is also shown in longitudinal section in the drawing and is arranged on the left-hand side and is firmly connected to the stepped bearing journal (2) Printing system provided.
  • This axial bearing (4) consists of an inner bearing ring (11) attached to the bearing journal (2), which counteracts axial displacement on the journal (2) is secured by support and retaining rings (12, 13, 14, 15), and from an outer bearing ring (16) with intermediate support rings (17) and bearing rollers (18).
  • the outer bearing roller support ring (17) is supported in the axial direction by a ring (19) with a flange which is firmly connected to the outer bearing ring (16).
  • the outer bearing ring (16) of the axial bearing (4) is provided on the outside with an annular extension (20) with a sealing ring (21) which is slidably guided in an axially movable manner in a cylindrical recess (22) of the bearing housing (23).
  • an annular disc (24) with a sealing ring (25) is attached, which seals the cylindrical recess (22) in the bearing housing (23) to the outside in a pressure-tight manner.
  • the axial displacement path of the roller (1) which in practice lies between about 0 and 400 mm, can be easily monitored and adjusted and / or adjusted at any time even during the rolling operation.
  • the bearing housing (23) is sealed to the outside by an end cover (35) and between the roller body (1) and the roll stand (6) there is a rubber for this -elastic cuff (36) arranged.
  • the device designed according to the invention can be used not only very advantageously for the axial displacement of work rolls and backup rolls in the stand of a hot or cold rolling mill, but also in rolling mills, for. B. for crushing hard materials or the like.
  • the device according to the invention is particularly characterized by its very simple and compact, after externally closed, easily accessible, easy to assemble or disassemble and easy to maintain design that can be retrofitted to existing rolling mills at any time.
  • the roller shifting device according to the invention can be used very advantageously in duo, four-high, six-high and special rolling mills.
  • the measures according to the invention are not limited to the exemplary embodiment shown in the drawing figure.
  • the radial bearings can have any shape, for example several radial bearings can also lie one above the other.
  • the respective structural design is left to the person skilled in the art to adapt to the specific use.
