Description

Die Erfindung betrifft ein verstellbares Bandschleifwerkzeug, mit einem endlos umlaufenden Schleifband und einem das Schleifband im Schleifbereich abstützenden Schleifmodul, das eine profilierte, dem Schleifbandrücken zugewandte Führungsfläche aufweist, welche einen zu schleifenden Rundungsradius darstellt, wobei das Schleifmodul an einem quer zur Schleifrichtung angeordneten Grundkörper mittig drehbar gelagert ist und an seinem Umfangsprofil wenigstens zwei Viertelkreiskonturen mit unterschiedlichen Radien aufweist, welche die jeweilige Führungsfläche für das Schleifband bestimmen.The invention relates to an adjustable belt grinding tool, comprising an endlessly circulating grinding belt and an abrasive module supporting the grinding belt back, which has a profiled, facing the grinding belt back guide surface which represents a radius to be ground Rundungsradius, wherein the grinding module rotatably centered on a transversely arranged to the grinding direction body is mounted and at its circumferential profile has at least two quadrant contours with different radii, which determine the respective guide surface for the grinding belt.

Derartige Vorrichtungen zum Schleifen gerundeter Kanten eignen sich im allgemeinen zum Nachbearbeiten von Kreissegmenten an geraden, rechtwinkeligen Werkstücken, vorwiegend aus Holzwerkstoffen, wie Treppenstufen, Möbelelementen oder dergleichen, welche damit zur Verfeinerung deren Oberflächen geschliffen werden können. Dies geschieht vorwiegend auf Maschinen mit einer Transporteinrichtung für den linearen Werkstückvorschub und einem daran angeordnetem Bandschleifaggregat. Dabei kommen entsprechend geformte Werkzeuge aus Kunststoff, Holz, Metall oder aus Verbundwerkstoffen zum Einsatz. Auch sind Werkzeuge aus Metall bekannt, welche jeweils für eine bestimmte Radiendimension gefertigt sind und durch welche während des Schleifvorganges Druckluft durch darin angebrachte Bohrungen einströmt und somit die Reibung zwischen Schleifband und Werkzeug vermindert.Such devices for grinding rounded edges are generally suitable for reworking circular segments on straight, rectangular workpieces, predominantly of wooden materials, such as steps, furniture elements or the like, which can thus be ground to refine their surfaces. This happens mainly on machines with a transport device for the linear workpiece feed and a belt sander arranged thereon. Appropriately shaped tools made of plastic, wood, metal or composite materials are used. Also, metal tools are known, which are each made for a specific radius dimension and through which during the grinding process compressed air flows through holes therein and thus reduces the friction between the grinding belt and tool.

Um bei diesen Verfahren Schleiffehler am Werkstückanfang und an dessen Ende zu vermeiden, ist eine Vorrichtung erforderlich, welche den exakten Einsatz des Schleifschuhes am Werkstückanfang und dessen Abheben am Werkstückende ermöglicht. Der Austausch dieser Einzelwerkzeuge zum Ändern der Profilform und ihre Positionierung im Bandschleifaggregat erfordern entsprechende Rüstzeiten. Ein wesentlicher Nachteil der bekannten Bandschleifvorrichtungen liegt auch darin, daß die Übergänge zwischen Rundungsbogen und den daran anschließenden geraden Flächen nicht sauber geschliffen werden, weshalb meist eine Nachbearbeitung von Hand erforderlich ist.In order to avoid grinding errors at the beginning of the workpiece and at the end of these methods, a device is required, which allows the exact use of the sanding pad at the workpiece beginning and its lifting at the workpiece end. The replacement of these individual tools to change the profile shape and their positioning in the belt grinding require corresponding set-up times. A major disadvantage of the known belt sanders is also that the transitions between the rounding sheet and the adjoining straight surfaces are not ground clean, which is why usually a post-processing by hand is required.

Um nicht für jede mögliche Profilform einen eigenen Schleifschuh vorsehen zu müssen, ist eine stufenlos einstellbare Bandschleifvorrichtung bekannt ( AT 413 958 B ), mit gegeneinander verschiebbaren Lamellen, welche sich einer profilierten Oberfläche durch Andrücken an ein entsprechendes Muster gegen den Widerstand eines elastischen Materials anpassen und sich in dieser Stellung durch Festspannen der Lamellen fixieren lassen. Dieser Vorgang muß jedoch bei einer Umstellung auf einen anderen Rundungsradius jedes Mal neu vorgenommen werden.In order not to have to provide its own sanding shoe for every possible profile shape, a continuously adjustable belt sanding device is known (US Pat. AT 413 958 B ), with mutually displaceable lamellae, which adapt to a profiled surface by pressing against a corresponding pattern against the resistance of an elastic material and can be fixed in this position by tightening the lamellae. However, this process must be redone each time you switch to a different rounding radius.

Bekannt ist auch ein Profilschleifaggregat ( EP 0 396 067 A2 ) mit einem Werkzeughalter, der als Werkzeugrevolver beschrieben ist, in dem verschiedene Werkzeuge ausgebildet sind.Also known is a profile grinding unit ( EP 0 396 067 A2 ) with a tool holder, which is described as a tool turret, in which various tools are formed.

Eine ähnliche Vorrichtung ist aus der EP 0 406 989 A1 bekannt, die ein Bandschleifwerkzeug der einleitend angegebenen Art betrifft.A similar device is from the EP 0 406 989 A1 known, which relates to a belt grinding tool of the type described in the introduction.

Es ist die Aufgabe der vorliegenden Erfindung, ein Bandschleifwerkzeug zu schaffen, dessen Führungsfläche für das Schleifband für eine Anzahl unterschiedlicher Radiusdimensionen rasch und exakt jeweils auf einen bestimmten Radius einer zu schleifenden gerundeten Kante eingestellt und damit das Herstellen des vom Werkzeug abgebildeten Profils einwandfrei erfolgen kann, wobei auch die Übergänge zwischen Bogenfläche und daran anschließenden ebenen Flächen sauber geschliffen werden sollen und diese Einstellungen jederzeit reproduzierbar sein sollen.It is the object of the present invention to provide a belt grinding tool, the guide surface for the grinding belt for a number of different radius dimensions quickly and accurately set each to a certain radius of a rounded edge to be ground and thus the production of the tool-formed profile can be done properly whereby the transitions between the curved surface and the adjoining flat surfaces should be ground clean and these settings should be reproducible at all times.

Diese Aufgaben werden erfindungsgemäß dadurch gelöst, daß das scheibenförmig ausgebildete Schleifmodul an dem Grundkörper mittig um einen Achsbolzen drehbar gelagert angeordnet ist, und daß im Grundkörper zwischen dem Schleifmodul und einer Deckplatte geführt zwei über Einstellschrauben verstellbare Bandführungselemente angeordnet sind, welche das Schleifband im Übergangsbereich von der Rundung zu den ebenen Flächen eines Werkstückes abstützen.These objects are achieved in that the disc-shaped grinding module arranged centrally rotatably mounted on the base body about an axle is, and that in the main body between the grinding module and a cover plate out two adjusting screws adjustable tape guide elements are arranged, which support the abrasive belt in the transition region from the rounding to the flat surfaces of a workpiece.

Gemäß einer Weiterbildung der Erfindung ist vorgesehen, daß das Schleifmodul kreisförmig angeordnete Indexbohrungen aufweist, über welche es in der dem jeweiligen Rundungsradius entsprechenden Stellung mittels eines Indexstiftes und einer Feststellschraube fixierbar ist.According to one embodiment of the invention, it is provided that the grinding module has circularly arranged index holes, by means of which it can be fixed in the position corresponding to the respective radius of curvature by means of an index pin and a locking screw.

Nach einem anderen Merkmal der Erfindung sind im Grundkörper zwischen dem Schleifmodul und einer Deckplatte geführt zwei über Einstellschrauben verstellbare Bandführungselemente angeordnet, welche das Schleifband im Übergangsbereich von der Rundung zu den ebenen Flächen eines Werkstückes abstützen.According to another feature of the invention are guided in the base body between the grinding module and a cover plate arranged two adjusting screws adjustable band guide elements which support the abrasive belt in the transition region from the rounding to the flat surfaces of a workpiece.

Mit diesen Maßnahmen wird sichergestellt, daß sich die Führungsfläche in gewünschter Weise derart einstellen läßt, daß sie genau dem Negativ einer zu fertigenden Rundungsform entspricht.With these measures it is ensured that the guide surface can be adjusted in the desired manner so that it corresponds exactly to the negative of a rounding shape to be produced.

Zur Minderung der durch das rasch umlaufende Schleifband erzeugten Reibung zwischen Führungsfläche des scheibenförmigen Schleifmoduls und der Bandführungsbacken sowie dem Schleifbandrücken ist es zweckmäßig, wenn erfindungsgemäß zwischen dem Schleifmodul und den Bandführungselementen einerseits sowie dem Schleifband anderseits ein Gleitbelag vorgesehen ist. Beispielsweise kann ein aus einem textilen Trägermaterial mit aufgebrachter Graphitschicht bestehender und entsprechend zugeschnittener Gleitbelag angebracht werden, dessen Dicke, ebenso wie jene des Schleifbandes, bei der Ausbildung der Rundungsprofile zu berücksichtigen ist.To reduce the friction generated by the rapidly rotating abrasive belt between the guide surface of the disc-shaped grinding module and the tape guide jaws and the sanding belt back, it is expedient if according to the invention between the grinding module and the tape guide elements on the one hand and the abrasive belt on the other hand, a sliding coating is provided. For example, a made of a textile substrate with applied graphite layer existing and appropriately tailored sliding surface are applied, the thickness of which, as well as those of the abrasive belt, is taken into account in the formation of the rounding profiles.

Die Anbringung des erfindungsgemäßen Bandschleifwerkzeuges an einem für den Schleifvorgang vorgesehen Bandschleifaggregat gestaltet sich einfach, indem dieses vorzugsweise über ein am Grundkörper anzubringendes Verbindungsteil zwischen den Schleifbandumlenkrollen mit der Maschine dergestalt fix verschraubt wird, daß die Mittenachse der längs der Werkstücktransportrichtung ausgerichteten Bandschleifvorrichtung in einem Winkel von 45° und im entsprechendem Abstand gegen die Werkstückkante weist.The attachment of the belt grinding tool according to the invention to a belt grinding unit provided for the grinding process is simple in that it preferably over a to be attached to the base body connecting part between the Schleifbandumlenkrollen with the machine is fixed screwed such that the center axis of the aligned along the workpiece transport direction belt grinding device at an angle of 45 ° and at the appropriate distance against the workpiece edge.

Eine beispielhafte Ausführungsform der Erfindung wird im folgenden an Hand der Zeichnung näher beschrieben. Es zeigen: Fig. 1 ein erfindungsgemäßes Bandschleifwerkzeug in Seitenansicht, Fig. 2 eine teilweise Schnittdarstellung der Bandschleifvorrichtung nach der Linie II-II in Fig. 3, und Fig. 3 das Bandschleifwerkzeug in der Draufsicht A in Fig. 1 auf ein symbolisch dargestelltes Schleifaggregat.An exemplary embodiment of the invention will be described in more detail below with reference to the drawing. Show it: Fig. 1 an inventive belt grinding tool in side view, Fig. 2 a partial sectional view of the belt grinder according to the line II-II in Fig. 3, and Fig. 3 the belt grinding tool in the plan view A in Fig. 1 on a symbolically illustrated grinding unit.

Die jeweils gültige Einstellung wird durch einen aus dem Grundkörper 3 ragenden Indexstift 8, welcher in eine der kreisförmig im Schleifmodul 4 angeordneten Indexbohrungen 7 eingreift, exakt festgelegt und kann so mittels Feststellschraube 6 fixiert werden.The respective valid setting is exactly determined by a protruding from the main body 3 index pin 8, which engages in one of the circular arranged in the grinding module 4 index holes 7, and can be fixed by means of locking screw 6.

Die Einstellung auf eine andere Rundungskontur bzw. einem anderen Rundungsradius erfolgt durch Lösen der Feststellschraube 6, Abziehen des Schleifmoduls 4 auf dem Achsbolzen 5 aus dem Eingriffsbereich des Indexstiftes 8 und entsprechendes Verdrehen und Fixieren in der gewünschten Stellung. Ebenso kann nach Abnahme der Feststellschraube 6 die Profilscheibe 4 gegen ein Schleifmodul mit anderen Rundungskonturen bzw. Rundungsradien oder gegen ein Einzelsegment für spezielle Rundungskonturen ausgetauscht werden.The setting to another rounding contour or a different radius of curvature is done by loosening the locking screw 6, removing the grinding module 4 on the axle 5 from the engagement region of the index pin 8 and corresponding twisting and fixing in the desired position. Likewise, after removal of the locking screw 6, the profile disk 4 can be exchanged for an abrasive module with other rounding contours or rounding radii or against a single segment for special rounding contours.

Fig. 3 zeigt in der Draufsicht A von Fig. 1 schematisch die mögliche Einbauanordnung eines erfindungsgemäßen Bandschleifwerkzeuges 1 in einem symbolisch durch die Schleifbandrollen 14, 15 und 16 sowie einem umlaufenden Schleifband 11 dargestellten Schleifaggregat, wobei ein Schleifvorgang an einem daran entlang geführten Werkstück 2 ausgeführt wird.
