Definitions

  • the invention relates to a device for applying a brush to a roller, e.g. in rolling mills or strand guiding devices, in particular on the working and / or supporting roll of a rolling stand for hot rolling aluminum, according to the preamble of patent claim 1.
  • each brush roll holder is arranged on the work roll chock, furthermore, the holder has a pivot lever which is located between a controllable actuating element and a restoring support element, wherein the actuating element arranged in the balancing block or bending block for the work rolls and the support element on the work roll chock are.
  • the actuating element is a hydraulically double acted piston-cylinder unit whose piston shaft rests on the pivot lever.
  • the support element consists of the pivot lever abutting support rod and a support cylinder, wherein the support rod against a spring assembly in the support cylinder is submersed and the support cylinder is pivotally mounted (bearing block) on the work roll chock.

It should be improved with such trained device for the employment of a brush roller, the previously used Bürstenanstellsysteme and in particular on such scaffolding, where the installation and conversion ratios are extremely cramped.
  • the advantage is to be achieved that there is no relative movement in the vertical plane between the brush holder and the chock. There is also no relative movement between the holder, the actuating element and the support element present. Compared to the previously known solutions, there is also no change in the lever ratios and, consequently, no change in the contact pressure of the brush roller to the work roll when changing the scaffold run. In addition, going to be a very space-saving Achieved design that could be integrated into existing structural elements of the rolling stand. In a work roll change no complex assembly or disassembly measures or additional adjustments are required.
  • the operation of the described embodiment is such that in a setting position for the brush roller, these brush roller and the work roll are preset to a Wegabstandshunt.
  • Superficial concern of the two parts can be effected by actuation of the piston-cylinder unit.
  • a hydraulic pressure medium is forced into the cylinder space of this actuating element, whereby the piston and the piston shaft is lowered in the direction of the roll chock.
  • the head of the piston rod pushes down the pivot lever of the holder at the contact surface against the spring force of the support member down, whereby the brush roller is moved to the work roll until it abuts against this.
  • the piston shaft of this unit moves upward and the spring-loaded support rod moves to the same extent upwards and acts on the pivot lever such that the holder of the brush roller and thus the brush roller itself to the pivot bearing pivots away down to a predetermined distance between the two rollers.
  • This distance is set by appropriate adjustment of a limiting element on the support rod adjustable.
  • the DE-OS 21 50 781 refers to a rotary brush adjusting device for cleaning the work rolls of a quarto scaffolding. It is envisaged that the bearings of the brushes are attached to rings which are rotatably mounted on the roller-side bearing caps of the backup roll chocks. In one embodiment, the rings are provided with an outer toothing, in which on the side facing away from the work roll, a drive pinion engages. It is further provided that the pinion is mounted on a shaft mounted in the chock, on whose exiting on the outside of the stator end an adjusting lever is rotatably disposed on which the piston rod of a mounted on the chock pressure cylinder is attached.
  • the brush bearings are intended to be guided exactly by the rings, wherein, as mentioned, the rings may be provided with an outer toothing, in which on the side facing away from the work roll, a drive pinion engages.
  • the piston rods engage each with an adjusting lever, which is anchored to the emerging on the outside of the chocks ends of the waves.
  • the present invention seeks to improve or further develop the known devices for the employment of a brush while maintaining the previous advantages in such a way that with simple means regardless of the roll diameters used and their working positions as well as regardless of the wear of the brush a constant contact force can be adjusted.
  • the adjusting device for the brush comprises at least one rotatably arranged in relation to the pivot lever adjusting element and a force transmission element for forming an operative connection between the pivot lever and the adjusting element; a monitoring device is provided for monitoring the angle of rotation of the Vestelliatas with respect to the pivot lever; and a control circuit is provided for keeping constant the adjusting force of the brush against the roller to a predetermined desired force F 0 by balancing or keeping constant the monitored by the monitoring device rotation angle via at least one actuator.
  • a device for hiring a brush is created for the first time by simple means, in which regardless of the roll diameters used and their Pakistanpositonen and also regardless of the wear of the brush, a constant contact force can be adjusted.
  • the parameters which change during, for example, rolling, such as roller wear (smaller diameter), brush wear or a changed position of the rollers have no influence on the amount of the setting force because their changes are automatically compensated by the construction according to the invention. This also applies to changing diameters or working positions when changing roles.
