Definitions

  • the invention relates to a grinding machine for wet grinding with a rotating device for receiving a roller to be ground containing a weak profile, with a measuring arm, one end of which is connected to the support of the grinding stone and at the other end of which is arranged movably in the direction of the axis of the rotating device Bracket is located, which contains a component to maintain a constant distance from the surface of the roller and is attached to the holder, the probe of a measuring or testing device for monitoring and controlling the manually controlled or automatically controlled grinding process.
  • the component for maintaining a constant distance from the surface of the roller is contactless and consists of a known contactless measuring part and an adjustment device attached to the measuring arm for a holder and to the holder more than one probe of test or measuring devices is installed, which are in the test or measuring state with grinding grindstone and rotating rotating device.
  • the part which measures the distance without contact is an air nozzle which is connected to a piston moving the holder to or from the roller through a channel in such a way that changes in the dynamic pressure cause the piston to move in the direction of restoring the desired Effect distance.
  • Another way to measure the distance without contact is to use a device that measures magnetic induction.
  • This device is not quite as precise as an air nozzle, because the magnetic induction changes in addition to the distance with structural changes on the surface.
  • Another disadvantage is that an electric actuator is necessary to correct the distance.
  • the change in diameter of the roller can be determined particularly precisely and easily if a length measuring device is installed between the measuring arm and the holder. Every change in the diameter of the roller leads to an adjustment movement of the holder, as a result of which the holder changes its position or distance from the measuring arm. These changes are proportional to the change in diameter. Any length measuring device can be used.
  • the relatively complex device for precise spacing of the bracket is used twice or more if the bracket additionally z.
  • the device for measuring the diameter changes is also used several times if it is also used for the precise alignment of the roller in the turning device.
  • the alignment device of the bearings of the rotating device is connected to the length measuring device on the measuring arm via a memory and comparator.
  • the grinding machine advantageously contains a pre-programmable automatic control for the movement of the grindstone perpendicular to the axis of the rotating device and for the movement of the support parallel to the axis of the rotating device, which are connected via a comparator to the length measuring device on the measuring arm.
  • the grinding machine 11 can be moved with the grinding stone 12 on the support 13 parallel to the axis of rotation 14 of the rotating device 15. In addition, the grinding machine 11 can still be moved in the direction of the axis of rotation 14.
  • the measuring arm 16 is fastened to the grinding machine 11, on which in turn a holder 17 is fastened via an adjusting device 18.
  • the air nozzle 19 and a probe 20 for crack testing are located under the holder 17.
  • the grindstone 12 is moved against the roller 21 to be ground and grinds it while the roller 21 is rotated by the rotary drive 15.
  • a length measuring device installed in the housing of the adjusting device 18 continuously measures the changes in diameter of the roller 21 in the area just ground.
  • the adjustment device 18 holds the holder 17 at a uniform distance from the surface of the roller 21, so that the air nozzle 19 on the holder 17 is at a distance of approximately 0.2 mm from the surface of the roller 21.
  • the roller 21 is deliberately ground somewhat spherically, as is required in rolling mills for the production of sheet steel.
  • the crowning is shown in FIG. 2.
  • the measurement results of the changes in diameter can also be shown as a curve on a screen over the length of the roller, as shown in FIG. 3. The operator can see the grinding processes still required from the comparison with the target curve and the actual curve.
  • the bearings 26 and 27 of the steady rests can be adjusted by drives, not shown. These drives are powered by the Measuring devices 22 to 25 controlled automatically.
  • the measuring devices 22 to 25 are constructed on the same principle as the already operated air nozzle 19 and adjusting device 18.
  • the measuring devices 22 and 23 can be saved if the measuring arm 16 is moved along the roller 21 for the purpose of measurement and the measurement results at the edge of the end face of the roller 21 are compared.
  • the measurement of the absolute diameter of the roller to be ground is possible if two measuring probes opposite each other on the roller are attached to a common measuring bracket.
  • the determination of the absolute diameter is e.g. B. important for the pair of grinding of the rollers, since the same peripheral speeds must be present in the roll stand. These are only available if the rollers have exactly the same diameter.
  • the grinding machine can not only grind symmetrical profiles, according to FIG. 2. There are also z. B. pear-shaped profiles, corresponding to FIG. 5, possible.
  • the device can of course also be used in the simplest case when the roller without a profile z. B. is purely cylindrical.
