Definitions

  • the invention relates to a device for processing in Roll stands mounted on chocks according to the generic term of claim 1.
  • a similar online grinder has also become known where the massive grinding wheels are made by flexible grinding wheels were replaced and in which the grinding wheels with drives are coupled.
  • JP-A 59-35819 which is the generic document represents, a compression frame with a device is known become, in which each of the roll of a stator to be ground Has a U-shaped chock in which the grinding roller the upsetting roller is arranged to be adjustable.
  • These for upsetting rolls trained solution is however not with conventional Quadro scaffolding applicable.
  • the sanding rollers as such should have greater hardness have than the work rolls. Influencing the contour of the bale the rollers to be ground is not possible.
  • JP-A 59-035821 discloses a similar grinding device for Upsetting rolls, the grinding rolls of which, however, do not cover the whole Width of the upset roller to be ground extends.
  • To the complete Sliding drives are provided to be able to grind the upsetting roller, by means of which the grinding rollers travel long distances along the Have to cover upset roller. Can during the rolling process so that only small areas of the upsetting roller are ground. Always optimal grinding removal across the entire width of the roller is not guaranteed.
  • US-A 4 707 950 discloses a polishing ring which consists essentially of rubber and a wire as an amination having. Abrasives are applied to the surface of the ring.
  • the ring is preferred for the grinding or polishing process stretched on a wheel. This consists essentially of rubber
  • ring can mainly because of the high heat in rolling mills not be used for online grinding of rollers.
  • the invention has for its object a simple, inexpensive Device for grinding rolls during rolling operation to create the little space in the area of the tape entry or exit side needed, not disturbing in appearance when changing rollers occurs and by means of which very complex grinding contours can be achieved are.
  • the elastically constructed shell of the role which consists of an elastic Containers can also be brush-like or mop-like Can have structure, on the one hand ensures that the hard abrasives also bends the roll without being damaged survives, and on the other creates smooth transitions on the ground Rolling elements.
  • the additional axial oscillation of the whole or the divided Role according to claim 4 can further to even out the Contribute roller contour.
  • the control device according to claim 7 ensures that the actual contour the roller can be optimally brought up to a target contour.
  • Fig. 1 shows work rolls 1, 2 and backup rolls 3, 4 of a four-high stand.
  • the work rolls 1, 2 are in chocks 5, 6 and Back-up rolls 3, 4 stored in chocks 7, 8.
  • the chocks 5 to 8 are guided against each other in a stand.
  • rollers 9, 10 are also stored, the via guides, not shown, to the work rolls 1, 2 or can be moved away from these.
  • Setting cylinders 11, 12 take care of the Employment. In the area of the inlet of the belt 13 are therefore only the rollers 9, 10 are provided, while the positioning cylinders 11, 12 outside of this area housed in chocks 5, 6 are.
  • FIG. 1 also shows a control device 14, the actual roll contour values are supplied via actual value sensors 15, 16.
  • the setpoints are fed via an input / storage unit 17.
  • the Outputs 18, 18 ', 18' ', 18' '' of the control device 14 work on the positioning cylinders 11, 12 as well as on rotating, not shown, Bending and axial sliding drives.
  • Fig. 2 shows the roller 9, which in the chocks 5, 5 'of the shown work roll 1 is guided.
  • the roller 9 has one Roller body 19 and an existing elastic container Roll jacket 20, in which abrasive 21 is embedded.
  • Of the Roll 9 are next to the pitch cylinders indicated only by the active arrows 11, 11 'also represented only by active arrows Rotary drive 22, an axial displacement drive 23 and Bending drives 24, 24 'assigned.
  • the roller 9 ' is divided into four sections on a shaft 25 rotatably mounted in the chocks 5, 5 ' support.
  • the support takes place via elastic sleeves 26, 26 ', 26 '', 26 '' ', the slight pivoting movements of the roller sections allow on shaft 25.
  • a driver 27 on the shaft 25 engages in not shown groove of the roller sections.
  • FIG. 4 shows an axis 28 guided in the chocks 5, 5 ' the axis 28 coaxial shafts 29, 30, 31, 32 are mounted, the individually drivable via rotary drives 22 ', 22' ', 22' '', 22 '' '' or can be braked.
  • the individual roller sections 19 ', 19' ', 19' '', 19 '' '' are with the shafts 29, 30, 31, 32 via not shown Driver non-rotatably connected.
  • actuators 11 are 11 ', axial displacement drives 23 and bending drives 24, 24' are provided.
  • the bearing of the roller sections on the shafts 29, 30, 31, 32 can of course also via elastic sleeves respectively.
