Abstract

The invention relates to a rubber hog disk with at least two different grinding segments and consisting of several rings. Each segment is located on a separate ring and the rings are detachably joined to each other.

Description

Gegenstand der vorliegenden Erfindung ist eine Rubber Hog Scheibe mit mindestens zwei verschiedenen Schleifsegmenten.The present invention relates to a rubber hog disk with at least two different grinding segments.

Aus der DE-A-890 911 sind Schleifscheiben bekannt, die für das Schleifen von Hartmetallwerkzeugen geeignet sind und an einer oder beiden Stirnflächen auf einer Ringzone der Mantelfläche mit Diamant- oder anderem Schleifmittelbelag versehen sind und die aus mehreren einzelnen Scheiben zusammengesetzt sind.From DE-A-890 911 grinding wheels are known which are used for grinding of carbide tools are suitable and on one or both End faces on a ring zone of the outer surface with diamond or other abrasive coating and which consist of several individual panes are assembled.

Aus der EP-A-0 589 142 sind Schleifscheiben bekannt, die auswuchtbar ausgestaltet sind.Grinding wheels which can be balanced are known from EP-A-0 589 142 are designed.

Rubber Hog Scheiben sind spezielle Schleifscheiben und werden benutzt zur Oberflächenbearbeitung von Elastomeren, insbesondere der elastomeren Schicht von mit Elastomeren beschichteten Walzen.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 Scheiben bestehen bisher aus einem Metallring, welcher an seiner Peripherie beschichtet ist mit Wolframcarbid verschiedener Körnungen. In der Praxis bewährt haben sich Rubber Hog Scheiben, welche in der Mitte ein Segment mit feinkörnigem Wolframcarbid aufweisen und seitlich hiervon einen oder zwei Segmente mit gröberkörnigem Wolframcarbid. Insbesondere um mit den Rubber Hog Scheiben in zwei Richtungen arbeiten zu können, weisen diese Rubber Hog Scheiben ein zentrales Segment mit feinkörnigem Wolframcarbid auf und auf beiden Seiten Segmente mit gröberkörnigem Wolframcarbid.So far, rubber hog discs consist of a metal ring, which is attached its periphery is coated with tungsten carbide various Grits. In practice 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. Especially with the 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.

Besonders bewährt haben sich derartige Rubber Hog Scheiben mit mehreren Schleifsegmenten, bei denen die seitlichen Schleifsegmente abgeschrägt sind, weil dadurch die Wärmebelastung der elastomeren Schicht gleichmäßiger verteilt wird.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 Scheiben werden beispielsweise hergestellt und vertrieben von den Firmen LRO-Europe B.V.B.A. sowie Sprangers B.V.B.A.For example, rubber hog disks are manufactured and sold by the companies LRO-Europe B.V.B.A. as well as Sprangers B.V.B.A.

Die Körnungen des Wolframcarbids werden auf Wunsch des Benutzers ausgewählt aus den Bereichen zwischen 170 und 550 µm. Der Benutzer der Rubber Hog Scheiben kann dabei für verschiedene Elastomere verschiedene Kombinationen der Körnung der Schleifsegmente bestellen. Die Körnungen der Schleifsegmente werden dabei ausgewählt nach den Anforderungen, die das jeweilige Elastomere stellt. Diese Anforderungen sind abhängig vom verwendeten Material und insbesondere den Härten der zu bearbeitenden Elastomeren, die im Bereich zwischen Shore-Härte von 10 Shore A bis 100 Shore D liegen können.The grains of the tungsten carbide are made at the request of the user selected from the range between 170 and 550 µm. 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.

Bei der Bearbeitung von elastomeren Schichten auf Walzen entstehen je nach Material und eingesetzten Rubber Hog Scheiben Oberflächen, die für technische Walzen ausreichend sind. Dabei ist jedoch zu beachten, dass die Qualität der entstehenden Oberflächen auf den Walzen mit zunehmendem Verbrauch der Wolframcarbidkörner qualitativ schlechter und ungleichmäßiger ausfallen. Insbesondere wird die Qualität der Oberflächen beeinflusst durch während der Benutzung entstehender Unwuchten. Während neubeschichtete Rubber Hog Scheiben im allgemeinen gut ausgewuchtet geliefert werden, ist ein nachträgliches Auswuchten der Rubber Hog Scheiben beim Benutzer nicht möglich.When processing elastomeric layers on rollers, each arise by material and rubber hog disc surfaces used for technical rollers are sufficient. However, it should be noted that the quality of the resulting surfaces on the rollers increasing consumption of tungsten carbide grains is of poor quality and turn out more uneven. In particular, the quality of the Surfaces influenced by the resulting during use Unbalance. While re-coated rubber hog discs in the Delivered generally well balanced is an ex post It is not possible for the user to balance the Rubber Hog disks.

Ein weiterer Nachteil der bisher zur Verfügung stehenden Rubber Hog Scheiben ist, dass die einzelnen Schleifsegmente unterschiedlich schnell verbraucht werden. Eine Neubeschichtung der Rubber Hog Scheiben ist dann aber insgesamt notwendig. Zur Neubeschichtung der Rubber Hog Scheiben werden diese an den Lieferanten zurückgeschickt und kommen im allgemeinen erst nach zwei bis vier Wochen wieder zum Benutzer zurück. Schließlich machen unterschiedliche Elastomere die Vorratshaltung von vielen unterschiedlichen Rubber Hog Scheiben notwendig, deren Schleifsegmente unterschiedliche Kombinationen der Körnungen des Wolframcarbids aufweisen.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.

Die Erfindung hat sich die Aufgabe gestellt, die oben genannten Nachteile zu vermeiden und Rubber Hog Scheiben zur Verfügung zu stellen, die einfach unterschiedliche Schleifsegmente miteinander kombinierbar machen und bei Verbrauch einzelner Schleifsegmente nur diese neu zu beschichten. Schließlich sollte die Rubber Hog Scheibe auch nachträglich beim Benutzer auswuchtbar sein. Lagerhaltung, Versand und Handhabung der Rubber Hog Scheiben sollten vereinfacht werden.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.

Diese Aufgabe wurde jetzt gelöst durch eine Schleifscheibe mit mindestens zwei verschiedenen Schleifsegmenten, bei der sich jedes Schleifsegment auf einem separaten Ring befindet und diese Ringe lösbar miteinander verbunden sind, und die Ringe sich auf einem gemeinsamen zentralen Grundkörper befinden, wobei es sich um eine Rubber Hog Scheibe handelt und zusätzlich ein oder zwei Ringe mit schneidenden Werkzeugen versehen sind.This task has now been solved with a grinding wheel at least two different grinding segments, in which 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.

Vorzugsweise sollte mindestens der zentrale Ring auswuchtbar ausgestaltet sein.Vorzugsweise ist der zentrale Ring mit der feinsten Körnung auswuchtbar ausgestaltet. Der oder die seitlich aufgesteckten und mit dem zentralen Ring verschraubten Ringe mit gröberer Körnung können zwar auch noch auswuchtbar ausgestaltet sein. Im allgemeinen genügt es aber, wenn der zentrale Ring Nuten aufweist, in welchen Gewichte eingebracht und hierin befestigt werden können. 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.

Die erfindungsgemäße Rubber Hog Scheibe besteht somit aus mehreren Ringen und weist zusätzliche Ringe mit schneidenden Werkzeugen auf. Fest miteinander verschraubte Kombinationen aus schneidenden Werkzeugen und Rubber Hog Segmenten bewähren sich insbesondere, wenn Durchmesser und Drehzahl der Rubber Hog Scheibe Schnittgeschwindigkeiten der Schneidwerkzeuge zwischen 10 und 150 m/s gestatten. Bei Schnittgeschwindigkeiten über 50 m/s verhalten sich nämlich Elastomere nicht mehr wie Elastomere, sondern wie Materialien, die üblicherweise mit Schneidwerkzeugen bearbeitet werden können.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.

In der anliegenden Figur 1 sind die Einzelteile der erfindungsgemäßen Rubber Hog Scheibe dargestellt, wie sie vorzugsweise ausgestaltet sind mit Ausnahme der schneidenden Werkzeuge.In the attached Figure 1, the individual parts of the invention Rubber hog disk shown as they are preferably designed with the exception of the cutting tools.

Hierin bedeutet

  • 1 ein zentraler Grundkörper
  • 2 ein zentraler Ring mit der feinsten Körnung
  • 3 seitlich aufsteckbare Ringe mit gröberer Körnung
  • 4 eine Spannscheibe
  • 5 Wuchtgewichte
  • 6 eine Schicht aus Wolframcarbid feiner Körnung
  • 7 eine Wolframcarbidschicht grober Körnung
    • Here means
  • 1 a central body
  • 2 a central ring with the finest grain
  • 3 rings with coarser grit that can be attached laterally
  • 4 a spring washer
  • 5 balancing weights
  • 6 a layer of fine grain tungsten carbide
  • 7 a coarse grain tungsten carbide layer

    • Wie man der Zeichnung entnehmen kann, lässt sich der Ring mit der feinerkörnigen Wolframcarbidschicht zunächst auf den Grundkörper aufstecken und mit der Spannscheibe 4 befestigen. Danach lassen sich die seitlichen Ringe mit gröberkörniger Wolframcarbidbeschichtung auf den zentralen Körper aufstecken und mit dem zentralen Ring fest verschrauben. Durch Einsetzen verschieden großer Wuchtgewichte 5 lässt sich die gesamte erfindungsgemäße Rubber Hog Scheibe auswuchten.As you can see from the drawing, 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.

    Durch Verwendung von Ringen 2 mit unterschiedlicher Beschichtung 6 einerseits und seitlichen Ringen 3 mit unterschiedlicher Körnung des Wolframcarbids 7 lassen sich beliebige Kombinationen der Körnungen 6 und 7 auf einer Rubber Hog Scheibe zusammenstellen. Bei schnellerem Verschleiß der Wolframcarbidschichten 7 auf den seitlichen Ringen lassen diese sich austauschen gegen neue. Die längerlebige Schicht auf dem zentralen Ring 2 kann dabei mehrfach benutzt werden, bis auch diese eine neue Beschichtung 6 benötigt. Zu einem zentralen Grundkörper 5 können somit durch einfache Lagerhaltung rasch und einfach verschieden kombinierte Rubber Hog Scheiben zusammengestellt werden, wobei kürzerlebige seitliche Ringe in größerer Anzahl auf Lager gehalten werden können, wohingegen man mit weniger zentralen Ringen mit feinerer Körnung des Wolframcarbids auskommt.By using rings 2 with different coatings 6 on the one hand and side rings 3 with different grain size 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.

    Es leuchtet ein, dass diese Rubber Hog Scheiben auch in verschiedenen Größen und Durchmessern hergestellt und zusammengestellt werden können.It makes sense that these rubber hog discs come in different sizes Sizes and diameters are manufactured and put together can.

    Schließlich werden seitlich auf die Ringe 3 weitere Ringe mit Schneidwerkzeugen aufgebracht, die bereits einen Teil des Elastomeren entfernen, welches sonst durch die gröberkörnige Wolframcarbidschicht zu entfernen ist.Finally, 3 more rings are attached to the side of the rings Cutting tools applied that are already part of the elastomer remove what would otherwise be through the coarser grain tungsten carbide layer is to be removed.
