Definitions

  • the invention relates to a polishing pad with an elastically compressible foam body, the opposing front and rear surfaces and can be attached by means of a fastening layer to a drive assembly.
  • the invention is preferably applicable to the machining of polishing agents. They are mainly used to process weathered old coatings and to polish sanding areas on fresh paint surfaces. For this purpose pasty or liquid polishing agents are used, which are applied to the polishing surface of an elastically compressible foam disk on the surface to be processed.
  • EP 0 379 361 B1 describes a Lackpolierarchitecture having a polymer foam layer having a plurality of spaced-apart protruding portions
  • the attachment of the polishing pads on the drive assembly is usually done by gluing or using a Velcro connection.
  • a foam consisting of polishing sponge having on its facing the drive element surface a Velcro layer which can be fixed with a Velcro connection to a sanding pad.
  • polishing wheels are made on machines that perform rotary or eccentric movements. By the rotation or vibration movements as well as by a necessary pressure on the surface creates heat.
  • the foams commonly used for production have the property of being softened by heat. As a result, the polishing pad deforms during use and compresses. This has the consequence that the processing times of the surface extend and the service life of the polishing wheels used is low.
  • the invention has for its object to provide a polishing pad of the type mentioned above, which is characterized by a long service life.
  • the polishing pad which is generally round and whose diameter is between 20 mm and 210 mm, on its polishing surface on the foam commonly used, in particular open-pore or closed-cell polyurethane foam, polymer foam or polyethylene foam.
  • This polishing layer is thinner than the previously used foam body.
  • the reduced thickness on the back is balanced by a stabilizing layer of heat resistant but flexible material.
  • temperature-resistant foams such as hide rubber or polyolefin can be used. But there are also other materials, such as felt applicable.
  • polishing pad too deep penetration of the polishing agent is prevented in the polishing pad. This also adds the durability and stability of the polishing pad improved and the polishing agent used is longer available at the polishing surface. Therefore, the service life of the single-layer polishing wheels is considerably prolonged, thereby achieving a cost reduction of the polishing processes.
  • the layer thicknesses of the foam body and of the support material used for the stabilization may preferably be the same.
  • the thickness and other dimensions of the stabilizing body can also be adapted to the particular application
  • the attachment of the foam body stabilizing body can be done as a solid compound, for example by gluing, laminating or Flammkaschieren or as a releasable connection, for example by a Velcro.
  • a cylindrical foam body 1 is fixedly connected to a cylindrical stabilizing disk 2.
  • Foam body 1 and stabilizing disk 2 are consistent in their outer shape and the diameter. They are firmly connected to each other by means of the bonding layer 3.
  • the stabilizing layer 2 is fastened on its upper side, ie on its side adjacent to the foam body 1, by means of the adhesive bond 3.1.
  • the attachment layer 4 is attached, with which the polishing pad can be attached to the tool.
  • the attachment layer 4 can be attached to the tool, for example by means of a Velcro connection.
  • FIG. 2 an embodiment is shown in which the cylindrical foam body 1 is releasably connected to the likewise cylindrical stabilizing disk 2.
  • the connecting layer 3 contains here a Velcro connection 3.2.
  • FIG. 3 shows an arrangement in which the stabilizing disk 2 has 2.1 breakthroughs.
  • the cylindrical openings 2.1 shown here run from the contact surface of the stabilizing disk 2 with the foam body 1 to the attachment layer 4.
  • the openings 2.1 favor the dissipation of heat otherwise accumulating in the polishing pad.
  • the diameter of the foam body 1 is larger than the diameter of the stabilizing disk 2.
  • the foam body 1 therefore has a projection with respect to the stabilizing disk 2.
  • the arrangement shown has a wave-shaped surface between the foam body 1 and stabilizing disk 2.
  • the structure may be angular or rounded and regular or irregular.
  • the structured design causes an uneven distribution of the contact pressure on the surface, thereby the polishing result can be improved and the heat development can be further reduced.
  • recesses are formed in the stabilizing disk 2, in which the polishing agent can collect and then, if necessary, for example by varying the contact pressure, can be available again on the workpiece surface.
  • Another advantage of the structured design of the contacting surfaces is that this results in an enlarged surface for connecting the layers and thus an even better durability is made possible among each other.
  • FIG. 6 illustrates a structured embodiment in which the surface between the foam body 1 and stabilizing disc 2 is concave, while in the in FIG. 7 shown embodiment of the foam body 1 is arranged in a cup-shaped stabilizing disk 2.
  • the embodiments as a trough or as a tub, in addition to the above-mentioned properties as a further advantage that the polish, which is applied to the surface to be polished, penetrates during processing in the foam body 1 to hold there because by the pressing of the Foam body 1 is pressed against the surface to be machined, the thinner outer edge of the foam body 1 and thus the penetrated polishing agent is not thrown by the centrifugal force to the outside. As a result, contamination of the surface to be machined is largely avoided.
  • FIG. 8 an arrangement is shown in which the foam body 1 surrounds the stabilizing disk 2 partially laterally. This is advantageous if lateral contact with the surface to be processed by the stabilization layer 2 has to be avoided.
