Definitions

  • the invention relates to a polishing device for polishing a component, with an elongate polishing element.
  • the prior art discloses methods and devices for regrinding the rolls, which are installed in particular in hot strip rolling mills. Due to the band contact the rollers take on tinder and other caking. These impurities are pressed on the next band on the surface of the belt to be wound. This leads to markings on the finished hot strip. To prevent this, the rollers are usually provided with a polishing or grinding device, which polish down the caking on the rollers at regular intervals.
  • EP 0154319 B1 describes a roll grinding device for rolling mills, with a housing for positioning the roll grinding device in the vicinity of a roll.
  • a housing guide which extends along the roll axis
  • a housing which is mounted in the transverse direction movable on the housing guide
  • the device is displaceable transversely to the roller.
  • a grindstone is arranged, which is movable relative to the roll axis back and forth.
  • EP 0824975 A1 describes a method and a device for regrinding the rolls installed in hot strip rolling mills, with at least one cup-shaped, rotationally driven grinding tool which is oscillatingly movable parallel to the roll axis.
  • EP 0573035 B1 describes a roll grinding arrangement which has a plan grinding wheel directed towards a roll of a pair of rolls for grinding this roll.
  • the grinding wheel is rotated via a grinding wheel drive means by means of a spindle, wherein a grinding wheel feed device is provided for pressing the grinding wheel to the roller.
  • a grinding wheel feed device is provided for pressing the grinding wheel to the roller.
  • an additional traversing device is provided for axial displacement of the grinding wheel.
  • the object of the invention is to provide a polishing device for components that is flexible, compact and cost-effective in terms of ease of maintenance and retrofitting, and that improves the quality of the polishing process.
  • This object is achieved by the features of claim 1.
  • a pressure element is designed as at least one pressurizable hose.
  • a tubular pressure element in conjunction with the divided into adjacent sub-segments polishing element, it is possible within a small installation space in the longitudinal extension of a component, a uniform force for pressing the polishing against to initiate the component.
  • the advantage is the seamless contour adaptation to the surface of the component in the longitudinal direction with identical pressure forces even for components with non-rectilinear or non-planar surfaces. Due to the compact size of the polishing device retrofitting in existing systems is flexible and inexpensive possible. Due to the few components, this polishing device is designed to be easy to maintain.
  • the pressure element is designed so that it can be acted upon by a pressure medium.
  • a pressure medium As a result of the system, it is possible, depending on the means provided, to apply the contact pressure for the polishing element hydraulically or pneumatically, which is advantageous especially for retrofitting into existing installations.
  • a control for controlling the pressure force of the pressure element is arranged.
  • a control for controlling the pressure force of the pressure element is arranged.
  • the polishing element is displaceably arranged within the housing on lateral guide surfaces.
  • the housing serves as an installation space and at the same time as a guide for the polishing element in order to ensure a guided, controlled and stabilized adjustment of the polishing element against the component. This dual function of the housing also saves additional installation space.
  • the invention provides that the polishing element is arranged in the housing such that only a portion protrudes on the working side of the polishing element with the projection A from the housing. This prevents that unnecessary space for the employment of the polishing element is claimed. Due to the short projection of the polishing element, the bending moment transmitted from the component to the polishing element is kept ring. Advantageously, the polishing element can thus be made smaller.
  • a stop is arranged on the housing which delimits the displacement path of the polishing element. The polishing element is thus safely guided in the housing and employed only up to the maximum possible working length of the component.
  • the polishing element is designed as a grindstone.
  • the polishing element is formed in the circumferential direction of the component in several parts in the form of sub-segments and locally adjustable individually.
  • the polishing element is the profile or the contour of the component not only in the direction of the longitudinal axis z adaptable, but also distributed over the circumference radially to the surface of the component can be adjusted. This results in a high quality, uniform typeface.
  • the component is designed in the form of a roller.
  • FIG. 1 shows the polishing device, consisting of a housing, a
  • FIG. 1 shows a polishing device 100 for a component 200, having an elongate polishing element 110, which can be set parallel to the longitudinal axis z of the component 200 against the surface 205 of the component 200.
  • a housing 120 is arranged, in which the pressure element 1 30 is mounted between a bearing surface 123 of the housing 120 and the polishing element 11 is.
  • the pressure element 130 is designed as at least one pressurizable hose and the pressure is applied hydraulically or pneumatically with a pressure medium.
  • a controller 300 controls the contact pressure of the pressure element 130 against the polishing element 1 10.
  • each pressure element 130 is preferably connected to a separate control 300 for adjusting the contact pressure of the polishing element 110.
  • the polishing element 110 is shown in the circumferential direction of the component 200 as a one-piece element.
  • the polishing element 1 10 in the circumferential direction of the component 200 is formed in several parts.
  • the polishing apparatus 100 can thus also adapt to a curvature in the circumferential direction of the component and, as a result, lies flat on the surface 205 of the component 200 even in these cases. This results in a better utilization of the polishing elements 1 10 and an improved, uniform microsection.
  • the polishing element is arranged in the housing 120 such that it protrudes with the smallest possible projection A from the housing. As a result, the bending moment introduced on the polishing element 110 is kept as low as possible when the polishing device 100 is pressed against the component 200. Via a guide surface 122, the polishing element 1 10 is guided in the housing 120.
  • a first stop 121 is arranged for the polishing element 1 10, against which the polishing element 1 10 abuts with a second stop 124.
  • the maximum working path of the polishing element 1 10 is reached and an exchange of the polishing element 1 10 required lent. This is usually done by a simple lateral pushing out of the polishing element 1 10 from the housing 120th
  • FIG. 2 describes in the direction of the longitudinal axis z the component 200 with the polishing device 100, which is set against the surface 205 of the component.
  • the polishing element 1 10 in the direction of the longitudinal axis z of the component 200 in adjacent sub-segments 1 10-1, 1 1 0-2, ... 1 1 0-n is formed.
  • This arrangement ensures a flexible adjustment of the subsegments, which is adapted to the roller contour, without gaps.
  • the pressure element 130 for hiring and pressing of the polishing element 1 10 against the roller surface 205 is arranged.
  • the polishing apparatus 100 shown in Figs. 1 and 2 is particularly useful for polishing a roll within a rolling mill to produce hot strip.
  • the polishing apparatus 100 is preferably used for polishing the pressure rollers of a hot strip reel, which bend the hot strip around a rotating coiler mandrel.
  • Another advantageous application of the polishing device 100 according to the invention is within a straightening machine for rolling, for polishing the straightening rollers. Due to the small space and the simple constructive and cost-effective design of the polishing apparatus 100, but other technical applications are conceivable, such for example, use in non-ferrous metal rolling mills, woodworking machines, bakery machines, printing presses, or even in cement plants. Wherever the product carrying rolls are exposed to contaminants, the surface of the rolls or rolls may be polished or ground with the polishing apparatus 100 of the present invention.
