Definitions

  • the invention relates to a device for employing a brush roller, in particular to the work roll of a roll stand for hot rolling aluminum, the brush roll being rotatable counter to the work roll rotation and translationally displaceable parallel to the work roll and being mounted on both sides in pivotable holders.
  • Brush systems on the work rolls of a rolling stand are required in order to remove any particles adhering to the rolls which would otherwise damage the surface of the rolling stock.
  • the brushes rotate in the opposite direction of the roller rotation and translate back and forth parallel to the roller axis by certain amounts.
  • the brush rolls When the work rolls are at a standstill, the brush rolls must be lifted from them, on the one hand to avoid pressure marks and images on the roll surface, and on the other hand to facilitate the removal and replacement of the work rolls.
  • a cassette design has been provided for the brush storage.
  • the bearing chock of the brush roller is enclosed by a C-shaped frame and held displaceably in it.
  • the displacement is caused by the pistons of two hydraulic units made, which are arranged opposite one another in the cassette frame and whose pistons engage the surfaces of the bearing insert intended for this purpose.
  • the object of the invention is to improve the brush adjustment system previously used, in particular on scaffolding where the installation and conversion conditions are extremely cramped.
  • the invention is characterized in that the pivot bearing of each brush roller holder is arranged on the work roll chock, that the holder has a pivot lever which is located between a controllable actuating element and a resetting support element, the actuating element in the balancing block or bending block for the work rolls and the support member is arranged on the work roll chock.
  • the advantage of the pivotable brush holder proposed here is that there is now no relative movement in the vertical plane that exists between the brush holder and the chock. There is also no relative movement between the holder, the actuating element and the support element. Compared to previously known solutions, there is no change in the lever ratios and, consequently, no change in the contact forces of the brush roller against the work roller when the scaffold rise changes.
  • the actuating element is a piston-cylinder unit that can be acted upon hydraulically twice, the piston shaft of which rests on the pivot lever. Hydraulic actuation has the advantage over a pneumatic or mechanical actuation element, for example, that very precise adjustment and controllable adjustment of the brush roller can take place, depending on the material used. The pressure on the brush roller can also be adjusted more sensitively in order to optimize the cleaning effect.
  • the support element consists of a support rod resting on the pivoting lever and a support cylinder, the support rod being immersed in the support cylinder against a spring arrangement and the support cylinder being arranged pivotably on the work roll chock.
  • the pivot lever of the holder is preferably connected to the support rod by means of a swivel joint. With this measure, a fixed position (constant Distance brush to work roll) for the brush roll.
  • the support rod can have a longitudinally adjustable stop or travel limiting element in the support cylinder.
  • the actuating element for the pivoting lever is arranged in the balancing block for the work rolls provided with at least one hydraulic cylinder. If a roll stand is only provided with roll bending or roll bending and CVC rolls, it is proposed that the actuating element for the pivoting lever be arranged in the fixed or displaceable bending block for the work rolls, which is provided with at least one hydraulic cylinder. So that the actuating element can engage directly on the pivoting lever of the brush roller holder without additional effort, it is provided that the piston-cylinder unit of the actuating element is arranged on the respective inner sides (towards the rolled strip) of the balancing or bending block.
  • a shaft piece with a one-sided connecting flange and opposing clamping coupling is rotatably mounted in the brush roller holder, the flange of which is connected to the brush roller and to a rotatably and translationally movable cardan shaft.
  • This compact design is completed in that the cardan shaft is expediently connected to a drive unit consisting of a hydraulically operating motor and a hydraulically acting oscillation cylinder, said drive unit being arranged on the work roll chock.
  • FIG. 1 shows a side view of the device according to the invention for placing the brush roller 1 against the work roller 2, for example a rolling stand for hot rolling aluminum.
  • a roll stand consists of roll stands 3, in which the lower and upper work rolls 2 are arranged, which are optionally supported by lower and upper support rolls, with all rolls being aligned in a vertical plane in the standing roll stand.
  • the respective rollers are held in bearings that are accommodated by chocks.
  • the chocks and the rollers can be exchanged or exchanged through the stand windows in the stand and are anchored in the stand.
  • the lower work roll 2 is mounted in the chock 4.
  • the chock has sliding plates 5, 6 on the side facing the balancing block, which in turn abut sliding plates 7, 8 on the balancing block 9.
  • the roller chock 4 is started with the balancing cylinder, not shown, which is arranged in the balancing block 9.
  • the device for adjusting the brush roller 1 to the work roller 2 shows a holder 10, in which the brush roller 1 is rotatably mounted and is translationally displaceable parallel to the work roller. In order to achieve a correspondingly good cleaning effect, the brush roller 1 and the work roller 2 rotate in the opposite direction; where the cleaning relative movement between the surface of the work roll and the bristles of the brush roll results.
  • the holder 10 of the brush roller 1 has a pivot lever 11.
  • the bracket is pivotally mounted in a pivot bearing 12.
  • the pivot lever 11 is located between an actuating element 13 and a restoring support element 14.
  • the support element 14 is arranged on the chock 4 of the work roll.
  • the actuating element is arranged either in the balancing block 9 or - if work roll bending is provided - in the bending block then present.
  • the actuating element 13 consists of a hydraulic piston-cylinder unit 15, the piston shaft 25 of which rests on the pivot lever 11.
  • the support element 14 consists of a support rod 17 connected to the pivot lever 11 and a support cylinder 18, the support rod 17 being immersed in the support cylinder against a spring arrangement 19.
  • the support rod has an adjustable limiting element 20.
  • the support cylinder 18 is pivotally held in a bearing block 21 on the work roll chock 4. The connection of the support rod 17 and the pivot lever 11 takes place with a fork-shaped enclosure 22 which is secured to the pivot lever 11 with a bolt.
  • Figure 1 shows that position for the brush roller, in which the brush roller 1 and the work roller 2 are preset to a minimum distance.
  • Superficial contact of the two parts can be brought about by actuating the piston-cylinder unit 15.
  • a hydraulic pressure medium is pressed into the cylinder space 23 of this actuating element, as a result of which the piston 24 and the piston shaft 25 are lowered downward in the direction of the roller chock 4.
  • the head of the piston rod 25 presses the pivot lever 11 of the holder 10 down on the contact surface 16 against the spring force of the support element 14, as a result of which the brush roller is moved towards the work roller until it bears against the latter.
  • FIG. 2 shows, partly in section, the work roll 2, the brush roll 1, the roll stand 3 and the actuating element 13, designed as a piston-cylinder unit 15, in the balancing block 9. Furthermore, the holder 10 for the brush roll and the pivot lever 11 can be seen, which is operatively connected to the piston skirt 25 of the piston-cylinder unit 15.
  • a shaft piece 26 with a one-sided connecting flange 27 and clamping coupling 28 is rotatably mounted, of which the connecting flange 27 is connected to the brush roller and the clamping coupling 28 to a rotatably and translationally movable cardan shaft 29.
  • a part of the shaft piece 26, the clamping coupling 28 and the cardan shaft 29 are passed through the work roll chock 4 and are connected to a drive unit 30, which is flanged to the outer surface 31 of the chock.
  • the drive unit 30 consists of a hydraulically operating motor, namely a hydraulic motor 32 and a hydraulically acting oscillation cylinder 33.
  • the brush roller 1 resting on the surface of the work roll 2 is both rotated and oscillated in the axial direction of the work roll by this drive unit.
  • the invention clearly shows that the object set out was achieved in an ideal manner by creating a compact adjusting device for the brush roller that is precisely adjustable, in which there is no relative movement between the holder, actuating cylinder and support element and in which no additional assembly work is required when the work rolls with their chocks have to be replaced.
  • a reversal of the arrangements of the elements of the adjusting device is also encompassed by the invention.
