Definitions

  • the invention relates to a polishing device for polishing a component with an elongate polishing element.
  • EP 0154319 B1 discloses a roll grinding device for rolling plants having a housing for positioning of the roll grinding device in vicinity of a roll.
  • the device is displaced transverse to the roll by means of a housing guide extending along the roll axis, with the housing being secured on the housing guide with a possibility of displacement in the transverse direction.
  • a grindstone is arranged, reciprocating relative to the roll axis.
  • EP 0824975 A1 discloses a method of and a device for regrinding rolls provided in a hot rolled strip rolling stand and having at least a pot-shaped rotatably driven grinding tool oscillatingly movable parallel to the roll axis.
  • the pressure force of the grinding tool is applied to the roll by means of displaceably driven compressed air means.
  • E 0573035 B1 discloses a roll grinding arrangement having a grinding disc extending toward a roll of a roll pair for grinding that roll.
  • the grinding disc is driven with a spindle by a grinding disc driving device, wherein for applying pressure of the grinding disc to the roll, there is provided a grinding disc displacing device.
  • a grinding disc driving device for applying pressure of the grinding disc to the roll, there is provided a grinding disc displacing device.
  • For axial displacement of the grinding disc an additional driving device is provided.
  • the drawback of the above-described known grinding devices consists in an expansive construction of the drive units for adjusting and displacement of the grinding device with respect to the component as well as in noticeably large mounting space necessary for arrangement of the grinding device with the drive unit and control elements.
  • the object of the invention is a polishing device for components which is flexible with regard to maintainability and regrinding, compact, can be cost-effectively mounted from several sides, and improves the quality of the polishing process.
  • the pressure element is formed at least as a pressurized hose.
  • the pressure element is formed at least as a pressurized hose.
  • the pressure element is so formed that it is pressurized with a pressure medium.
  • a pressure medium Dependent on the plant, it is thus possible to apply hydraulic or pneumatic pressure to the polishing element in accordance with available means, which is exactly the advantage of fitting in the existing plants.
  • a control for controlling the pressure force of the pressure element is provided.
  • the polishing element is displaceably arranged within the housing on a sidewise guide surface.
  • the advantage of this consists in that the housing serves simultaneously as a mounting space and as a guide for the polishing element, insuring a controlled and stable adjustment of the polishing element against the component.
  • the double function of the housing in addition, provides for saving of the mounting space.
  • the invention contemplates such an arrangement of the polishing element in the housing that only a portion of the polishing element projects from the housing with a distance A at the working point. Thereby, an unnecessary space for adjusting the polishing element is dispensed with. With a short projection of the polishing element, the bending torque transmitted by the component to the polishing element is kept small.
  • the polishing element can have smaller dimensions.
  • a stop is provided on the housing which limits the displacement path of the polishing element.
  • the polishing element is formed of a grindstone.
  • the polishing element is formed, in the circumferential direction of the component, of several parts in form of segment sections, and is locally individually adjusted.
  • the polishing element is adjustable with respect to the profile of the component not only in direction of the longitudinal axis Z but also is adjusted over its circumference radially with respect to the surface of the component. Thereby, a high quality, uniform grinding surface is formed.
  • the component has a shape of a roll.
  • FIG. 1 a polishing device formed of a housing, a pressure element, and an elongate polishing element adjustable against a workpiece;
  • FIG. 2 adjusting of the polishing device in a direction of a longitudinal axis of the workpiece with a hose-shaped pressure element.
  • FIG. 1 shows a polishing device 100 for a workpiece 200 and having a polishing element 110 adjustable parallel to the longitudinal axis Z of the workpiece 200 against a surface 205 of the component 200 .
  • a housing 120 for housing the polishing element 110 and a pressure element 130 that presses the polishing element 110 against the workpiece 200 , there is provided a housing 120 in which the pressure element 130 is supported between the bearing surface 123 of the housing 120 and the polishing element 110 .
  • the pressure element 130 is formed as at least pressurized hose, with the pressure being provided with pressure means hydraulically or pneumatically.
  • a control 300 controls the pressure applied by the pressure element 130 against the polishing element 110 .
  • each pressure element 130 is preferably connected with a separate control 300 for adjusting the pressure applied by the polishing element 110 .
  • the polishing element 110 is formed as a one-piece element in a circumferential direction of the workpiece 200 .
  • the polishing element can also be formed of several sections in the circumferential direction of the workpiece 200 .
  • the polishing device 100 can be adapted to a curvature of the workpiece in the circumferential direction and, thereby, would flatly abut the surface 205 of the workpiece 200 in this case. This results in a better use of the polishing element as well as in an improved, uniformed surface quality.
  • the polishing element is so arranged in the housing 120 that it projects from the housing with as small as possible projection A. Thereby, a bending torque applied to the polishing element 110 when the polishing device 100 is pressed against the workpiece 200 , is kept as small as possible.
  • the polishing element 110 is displaced in the housing 120 over a guide surface 122 . This makes possible a stabilized and linear adjustment of the polishing element 110 .
  • a first stop 121 for the polishing element 110 against which the polishing element 110 abuts with a second stop 124 In this case, a maximal working displacement of the polishing element 110 is achieved, and a replacement of the polishing element 110 is possible. This is usually affected by a simple sidewise push of the polishing element 110 out of the housing 120 .
  • FIG. 2 shows adjustment of the polishing device 100 relative to the outer surface 205 of the workpiece 200 in the direction of the longitudinal axis Z of the workpiece 200 .
  • the polishing element 110 is formed, in the direction of the longitudinal axis Z of the workpiece 200 , of adjustment sections 110 - 1 , 110 - 2 , . . . 110 -n. This arrangement insures a flexible, correspondingly adaptable, to the roll profile, adjustment of the sections without clearances therebetween.
  • the pressure element 130 is arranged for adjusting and pressing the polishing element 110 against the roll surface 205 .
  • the polishing device 100 which is shown in FIGS. 1 and 2 , is particularly suitable for polishing rolls within a roll train for producing a hot rolled strip.
  • the polishing device 100 is used for polishing pressure rollers of a hot rolled strip reel that bends the hot rolled strip about a reel mandrel.
  • a further advantageous field of use of the inventive polishing device 100 is in straightening machine for rolled goods for polishing the straightening rollers. Because o a small constructional volume, simple construction, and cost-effective design of the polishing device 100 , other technical uses are conceivable such a, e.g., the use within NE-metal rolling plants, wood treatment machines, backery equipment, pressure machines, or in concrete plants. Generally, everywhere where the rollers for removal of produce impurity are used, the surfaces of rollers or rolls can be polished or ground with the inventive polishing device 100 .
