Definitions
- the invention relates to a grinding device for rolling a Roll stand according to the preamble of claim 1.
- Such a grinding device is e.g. B. by DE-PS 34 06 160 became known.
- An abrasive belt is used here, the with an elaborate drive and guide unit grinding roller is brought into contact. These are around endless sanding belt.
- the disadvantage is that the grinding belt quickly unrolled from a supply roll, and then cumbersome to be wrapped or renewed.
- Rotatingly driven grinding elements are also known become.
- the a drive motor is assigned, on a bracket.
- the Grinding elements are driven such that they over short Oscillate areas along the roller to be ground.
- flexible electrical leads to the drives are provided be able to compensate for the axial movements.
- GB-A-535 481 includes an improvement in axially displaceable State-of-the-art support devices for grinding rollers, the one over almost the entire length of the to be ground Has workpiece-extending grinding roller, which over a Slightly adjustable handwheel in the axial direction on a guide is. Use of this device in rolling mills and one Pivotal movement of the device to drives executing the workpiece are not stimulated here.
- CH-A-298 599 discloses a grinding device based on a Guide along the workpiece is movable.
- the drive for the Rotational movement of the grinding roller is here on the guide carried, so that this drive motor are always moved must and therefore always in the sphere of influence of the worn Abrasive goods located.
- EP-A-03 11 820 discloses a pivoting headstock for a grinding wheel, by means of which the grinding wheel to the Workpiece can be pivoted, an axial displacement of the However, grinding wheel along the workpiece is in this grinding device not possible.
- the invention has for its object a generic Easy, safe and inexpensive to set up the grinding device.
- the rotatably drivable guide designed as a hollow shaft according to claim 2, as well as the driver projecting into the hollow shaft allow one simple attack of the sliding drive on the grinding element, wherein the spindle nut drive according to claim 4 or 5 a special Maintenance-friendly way shows turns in axial Convert displacement movements.
- the invention is illustrated by a schematic drawing described.
- the drawing shows, cut off, parts of the chocks 1, 1 ', of a roll stand in which an interchangeable cassette 2, 2 ', is installed.
- the exchangeable cassette 2, 2 ' carries the pins 3, 3 ', a rocker 4.
- An adjusting drive 5 is on the interchangeable cassette 2 supported and works via a gear 6 on the pin 3rd
- a guide 7 is rotatably mounted in the rocker 4. On the Guide 7 is a grinding element 8, for. B. a sanding mop, non-rotatable, however, axially slidably supported.
- the guide 7 is is a longitudinally slotted hollow shaft 7 ', which has a toothed belt 9 can be driven by a rotary drive 10.
- a threaded spindle 11 is mounted in the hollow shaft 7 '.
- the threaded spindle 11 is via a toothed belt 12 from a displacement drive 13, which is held on the rocker 4, can be driven in rotation.
- On the threaded spindle is a ball nut 14 mounted, which a driver 15, the hollow shaft 7 'in the area thereof shown slots penetrates, connected to the grinding element 8 is.
- the grinding device works as follows:
- the swing arm 4 can be pivoted in this way via the adjusting drive 5 be that the grinding element 8 is placed against the roller 16.
- the adjusting drive 5 be that the grinding element 8 is placed against the roller 16.
- the guide 7 and thus the grinding element 8 rotated.
- the sliding drive drives 13 the threaded spindle 11.
- the guide 7 and the threaded spindle 11 at the same speed operated, it remains on the driver 15 and the ball nut 14 in operative connection with the threaded spindle 11 Grinding element in the axial rest position.
- the speed of the threaded spindle 11 compared to the speed of the Guide 7 increases or decreases, the ball nut moves 14 on the threaded spindle 11 and thus shifts that Grinding element 8.
