Definitions

  • the invention relates to a device for bending the rolls in a multi-roll rolling stand with inlet and outlet side fixed between the Walzeneinbaustükken and the stator windows acted upon by actuating means bending blocks.
  • Generic devices are used for flatness control of a rolled product as an actuator for work roll bending.
  • the actuator has a direct influence on the nip geometry in the band edge region, wherein the work rolls are positively bent around the edges of the overlying rollers and bent negatively around the edges of the rolling stock.
  • German Patent 22 50 953 is a rolling stand with working and support rollers and a roll bending device in which the chocks of the work rolls between anchored in the stator blocks blocks and to act on the work rolls bale correction acted upon by both sides, the blocks associated piston cylinder Units are known, wherein on each block, a lower and an upper guide piece is guided vertically displaceable, whereas the one guide piece receives the cylinder and the other guide piece is connected to the piston, and the guide pieces with the chocks by horizontal guides in the vertical direction positively are connected, which are continued for the roll change between the stands parallel to the rollers. In this way it should be achieved that for rolling bending on each side two piston-cylinder units are required.
  • the invention has for its object to reduce the frictional forces in a generic system.
  • the bending blocks of a rolling stand, a piston cylinder and the bending blocks of the opposite roll stand is assigned a Vertikalpositionier device.
  • a Spindelhubgetriebes By positioning and locking the bending blocks by means of the vertical positioning device, preferably a Spindelhubgetriebes can create a pivot point around which the chock can be pivoted. Thus, only one cylinder is necessary to initiate the drive and operator-side bending force in the bending blocks.
  • the device according to the invention can also be used for the intermediate roll bending in a six-high stand.
  • a use in reversing rolling stands is conceivable.
  • a roll stand 1 the work rolls 3, 3a are supported by the support rolls 2, 2a.
  • the chocks 4, 4a of the work rolls are connected to the roll stand 6, 6 'via the bending blocks 5, 5a, 5', 5a '.
  • a screw jack 10 is arranged, which is positionable and lockable via a drive 12.
  • the bending blocks 5 and 5a are connected via a piston cylinder 7, the piston 9 is mounted in the bending block 5a, while its connecting rod 8 is mounted in the bending block 5.
  • the bending blocks 5, 5a, 5 'and 5a' can be connected to the chocks 4, 4a of the work rolls 3, 3a on the one hand and the roll stand 6, 6 'on the other hand in a known manner.
  • the rolling direction of the continuous rolling stock is represented by the double arrow 11.
  • the bending blocks 5 ', 5a' positioned and locked with the Spindelhubgetriebe, while the piston cylinder 7, which connects the bending blocks 5 and 5a together, initiates the necessary bending force.
  • the invention is not limited to the use of Spindelhubgetrieben, but it can be used on any mechanics for vertical positioning, for example. On wedges with positive guidance, cylinder with clamping head and position sensor or on an eccentric shaft.
