Definitions

  • the invention relates to a roll stand for rolling different rolling stock, which requires different rolling forces, with a lower and an upper work roll, the work rolls associated supporting trolleys, if necessary.
  • the hydraulic adjusting cylinders are used to generate the rolling force in rolling mills used.
  • the rolling mills a large variety of products is currently decisive, resulting in large rolling force differences between the. individual products arise for the same rolling stand.
  • JP - A - 62 130 705 is also not the arrangement of the telescopic cylinder between the chock and the roll stand.
  • the telescopic cylinder is rather located in the bottom of the roll stand and for the back-up rolls intended.
  • the invention is based on the object, in the generic rolling mill to reduce the friction losses, thereby achieving a more accurate control.
  • the adjusting cylinder each consist of a telescopic cylinder, in which a first, concentric Large diameter cylinder for high rolling forces and a second concentric one Cylinder with smaller diameter provided for small rolling forces are, wherein the pressure medium connection for the annular pressure chamber of the large Piston forms a connection to the bottom of the small piston.
  • the first, large cylinder with large diameter forms an outer, annular pressure chamber, the pressure medium presses a large piston ring against the cylinder bottom.
  • the large piston during operation of the smaller piston is at rest and with smaller rolling forces the friction at the large Piston is completely avoided and only friction on the smaller piston, the is much lower, arises.
  • the smaller piston of second cylinder of smaller diameter inside the big piston one Pressure chamber for actuating the smaller piston forms. This can be a Advantage of the telescopic system can be used, with a significant space savings connected is.
  • a further development provides that the pressure medium connection for the smaller piston through the cylinder wall and through the cylinder bottom of the larger cylinder is guided.
  • the advantage is in short media feeds and in one Distribution of the pressure medium connections on two sides of the adjusting cylinder.
  • a further advantageous embodiment results from the fact that the first, large Cylinder closable by means of a sealing ring sealing the large piston is to which the pressure medium connection for the outer, annular Pressure chamber is connected.
  • the end ring may face sealing rings accommodate the large piston and allows the formation of the annular pressure chamber.
  • the adjusting cylinder 3 each consist of a telescopic cylinder 4.
  • a first, large cylinder 5 with an outer, annular pressure chamber 5a, which has a large piston ring 5b provided.
  • the large piston 5d is with a large ring seal 6 in the cylinder housing 7 sealed.
  • the pressure medium connection 14 communicates with the pressure chamber 13 via a pressure medium channel 16, which passes through the upper portion of the cylinder housing 7, in Connection.
  • the second, smaller piston 15a is with corresponding sealing rings 17, 18, whose diameter is smaller, sealed in the second, smaller cylinder 15.
  • Another sealing ring 19 is located on the smaller piston 15a within the big piston 5d.
  • the pressure medium connection 14 leads the pressure medium through the Cylinder wall 5e and through the cylinder bottom 5c.
  • the smaller piston 15a is in the upper position and in the right half of the illustration in the lower position.
  • the pressure medium connection 11 provides for the large, annular pressure chamber 5a a connection 20 to the bottom 15b of the smaller piston 15a ago.
  • the smaller piston 15a of the second, smaller cylinder 15 with the smaller one Diameter in the interior 21 forms the pressure chamber 13 for actuating the small Piston 15a.
