Definitions

  • the invention relates to a device for controllably influencing the frictional forces between the guide surfaces and contact surfaces of, in the stand windows bearing chocks of the rollers guided by roll stands.
  • Devices of this type serve to counteract the vibrations which frequently occur when rolling sheet metal strips in multi-roll stands, in particular at higher rolling speeds, which entail the risk of vibration problems occurring. These vibrations can cause surface damage such as so-called Chatter marks "on the belts lead and also have a negative effect on the service life of the rolls. If rolling has to be carried out at lower rolling speeds in order to avoid these vibrations, the productivity of the rolling mill drops with the result of higher costs.
  • the invention is based, so the generic devices the task to improve that they apply the entire area to the pressure surfaces of the Bearing chocks with variable pressure forces to generate defined friction forces, enable regardless of the respective rolling conditions.
  • This task is carried out vertically in the upright windows to the guide or contact surfaces of the stand window and bearing chock slidably guided, flat, on the back supporting the guide surfaces pressurizable carrier plates released.
  • the invention further provides can be one that acts on the back of the carrier plate in the roller stand arranged piston-cylinder unit are provided.
  • the device allows defined contact forces and frictional forces on the bearing chocks in the stand window of the mill stand, bridging the operating game to generate, i.e. defined contact forces and friction forces independently specified by the rolling technology conditions.
  • the invention is based on the embodiment shown in the drawing explained in more detail.
  • the drawing shows a schematic representation of the partial view of one in the Stand spars SH1, SH2 formed stand window SF one, otherwise not Roll stand shown, seen in the roll axis direction.
  • the bearing chock LE of the roller W is in the stand window SF between the guide surfaces FF1 and FF2 of the window can be moved up and down in the direction of the double arrow DP guided.
  • the stand beam SH1 shown on the left in the drawing is in the boundary surface of the stator window SF is provided with a recess AS, into which a plane is slidably guided perpendicular to the guide surface FF1 Plate PL is inserted.
  • the plate PL can be on the drive side or on the operator side for back-up rolls, intermediate rolls and also use work rolls of a roll stand.
