Definitions

  • the present invention relates to a rubber hog disk with at least two different grinding segments.
  • Rubber hog wheels are special grinding wheels and are used for surface treatment of elastomers, especially the elastomeric layer of rollers coated with elastomers.
  • rubber hog discs consist of a metal ring, which is attached its periphery is coated with tungsten carbide various Grits.
  • rubber hog discs have proven themselves which in the middle is a segment with fine-grained tungsten carbide have and laterally one or two segments with coarser grain tungsten carbide.
  • Rubber Hog This rubber has the ability to work discs in two directions Hog disks on a central segment with fine-grain tungsten carbide and segments with coarser-grain tungsten carbide on both sides.
  • Such rubber hog disks have proven particularly useful several grinding segments, in which the side grinding segments are beveled because this causes the thermal load on the elastomer Layer is distributed more evenly.
  • rubber hog disks are manufactured and sold by the companies LRO-Europe B.V.B.A. as well as Sprangers B.V.B.A.
  • the grains of the tungsten carbide are made at the request of the user selected from the range between 170 and 550 ⁇ m.
  • the user the rubber hog discs can be used for various elastomers order different combinations of the grain size of the grinding segments.
  • the grain sizes of the grinding segments are selected according to the Requirements that the respective elastomer makes. These requirements depend on the material used and especially the hardness of the elastomers to be processed, which range between Shore hardness from 10 Shore A to 100 Shore D.
  • Rubber Hog Disks Another disadvantage of the previously available Rubber Hog Disks is that the individual grinding segments at different speeds be consumed. A new coating of the rubber hog discs is then altogether necessary. For re-coating the Rubber Hog Slices are sent back to the supplier and come generally only back to the user after two to four weeks back. After all, different elastomers do that Stock of many different rubber hog discs necessary, the grinding segments of different combinations of Have grains of tungsten carbide.
  • the invention has for its object the disadvantages mentioned above to avoid and to provide rubber hog disks that Different grinding segments can be easily combined and only use new ones when using individual grinding segments coat. Finally, the rubber hog disc should also be retrofitted be balanced by the user. Warehousing, shipping and Handling of the rubber hog discs should be simplified.
  • each Grinding segment is located on a separate ring and these rings are detachable are interconnected, and the rings are on a common central body, which is a rubber hog Disc acts and additionally one or two rings with cutting Tools are provided.
  • At least the central ring should preferably be balanced
  • the central ring is preferably the finest Grain designed to be balanced.
  • the one or the side and coarser grit rings screwed to the central ring can also be designed to be balanced. In general but it is sufficient if the central ring has grooves in which Weights can be introduced and attached therein.
  • the rubber hog disk according to the invention thus consists of several Rings and has additional rings with cutting tools. Combinations of cutting screws that are firmly screwed together Tools and rubber hog segments are particularly useful if diameter and speed of the rubber hog disc Cutting speeds of the cutting tools between 10 and 150 allow m / s. Behavior at cutting speeds above 50 m / s namely elastomers no longer like elastomers, but like materials, that can usually be machined with cutting tools.
  • the ring can be used with the fine-grained tungsten carbide layer first on the base body attach and secure with the tensioning washer 4. After that you can the side rings with coarser grain tungsten carbide coating attach the central body and secure with the central ring screw together. By inserting balancing weights of different sizes 5 leaves the entire rubber hog disk according to the invention is balanced.
  • Tungsten carbide 7 can be any combination of grain sizes 6 and 7 put together on a rubber hog disc. With faster Leave wear on the tungsten carbide layers 7 on the side rings these exchange themselves for new ones. The longer-lasting layer on the central ring 2 can be used several times until this too a new coating 6 is required. To a central base body 5 can therefore quickly and easily differentiate through simple warehousing Combined rubber hog discs are put together, whereby short-lived side rings are kept in stock in large numbers can, whereas with less central rings with finer Grain of the tungsten carbide gets along.
