Definitions
- the present invention relates to a rubber hog disk with at least two different grinding segments.
- Rubber hog discs are used for the surface treatment of elastomers, especially the elastomeric layer of rollers coated with elastomers.
- rubber hog discs consist of a metal ring, which is coated on its periphery with tungsten carbide of different grain sizes.
- Rubber Hog disks have proven themselves in practice, which have a segment with fine-grained tungsten carbide in the middle and one or two segments with coarser-grained tungsten carbide on the side.
- these rubber hog disks have a central segment with fine-grained tungsten carbide and segments with coarser-grained tungsten carbide on both sides.
- Such rubber hog disks with several grinding segments, in which the side grinding segments are chamfered, have proven particularly useful because this distributes the heat load on the elastomer layer more evenly.
- Rubber Hog disks are manufactured and sold by LRO-Europe BVBA and Sprangers BNB.A. - 2 -
- the grain sizes of the tungsten carbide are selected at the user's request from the range between 170 and 550 ⁇ m.
- the user of the Rubber Hog discs can order different combinations of the grit of the grinding segments for different elastomers.
- the grain sizes of the grinding segments are selected according to the requirements of the respective elastomer. These requirements depend on the material used and in particular the hardness of the elastomers to be processed, which can range from Shore hardness from 10 Shore A to 100 Shore D.
- the object of the invention is to avoid the disadvantages mentioned above and to provide rubber hog disks which simply make it possible to combine different grinding segments with one another and to re-coat only these when using individual grinding segments. Finally, the rubber hog disc should also be able to be subsequently balanced by the user. Storage, shipping and handling of the rubber hog discs should be simplified.
- each grinding segment of the rubber hog disc is on a separate ring and these rings are detachably connected to one another.
- These rings are preferably located on a common central base body, onto which they can be attached and are detachably connected to one another by screwing. At least one of these rings should be designed to be balanced.
- the central ring with the finest grain size is preferably designed to be balanced.
- the one or more laterally attached and screwed to the central ring rings with coarser grit can also be designed to be balanced. In general, however, it is sufficient if the central ring has grooves in which weights can be introduced and fastened therein.
- the rubber hog disk according to the invention consisting of several rings can also have additional rings with cutting tools.
- a combination of cutting tools and rubber hog segments that are firmly screwed together are particularly useful when the diameter and speed of the rubber hog. Allow disk cutting speeds of the cutting tools between 10 and 150 m / s. At cutting speeds above 50 m / s, elastomers no longer behave like elastomers, but rather materials that can usually be processed with cutting tools.
- the individual parts of the rubber hog disk according to the invention are shown as they are preferably designed.
- the ring with the fine-grained tungsten carbide layer can first be placed on the base body and fastened with the tensioning disk 4. Then the side rings with coarser-grain tungsten carbide coating can be placed on the central body and screwed tightly to the central ring.
- balancing weights 5 of different sizes the entire rubber hog disk according to the invention can be balanced.
- any combination of grain sizes 6 and 7 can be put together on a rubber hog disc. If the tungsten carbide layers 7 on the side rings wear out faster, they can be exchanged for new ones. The longer-lived layer The central ring 2 can be used several times until this also requires a new coating 6.
- a central base body 5 can thus be put together quickly and easily by combining rubber hog disks quickly and easily, whereby short-lived side rings can be kept in large numbers in stock, whereas less central rings with finer grain of tungsten carbide can be used.
