Description

Verstellbares Bandschleifwerkzeug Adjustable belt grinding tool
Die Erfindung betrifft ein verstellbares Bandschleifwerkzeug, mit einem endlos umlaufenden Schleifband, mit einem das Schleifband im Schleifbereich abstützenden Schleifmodul, das eine profilierte, dem Schleifbandrücken zugewandte Führungsfläche aufweist, welche einen zu schleifenden Rundungsradius darstellt.The invention relates to an adjustable belt grinding tool, comprising an endlessly revolving grinding belt, with a grinding module supporting the grinding belt in the grinding region, which has a profiled guide surface facing the grinding belt back, which constitutes a radius of curvature to be ground.
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 Maschi- nen 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 be- stimmte 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 known are tools made of metal, which are each manufactured for a specific radius dimension and through which compressed air flows through boreholes mounted therein during the grinding process and thus reduces the friction between the grinding belt and the 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 er- fordern entsprechende Rüstzeiten. Ein wesentlicher Nachteil der bekannten BandschleifVorrichtungen liegt auch darin, daß die Übergänge zwischen Rundungsbogen und den daran anschlie- Senden 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 for changing the profile shape and their positioning in the belt sanding unit require appropriate set-up times. A major disadvantage of the known belt sanding devices lies in the fact that the transitions between the arc and the subsequent thereto Sending straight surfaces should not be sanded 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 einstell - bare 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 fixie- ren lassen. Dieser Vorgang muß jedoch bei einer Umstellung auf einen anderen Rundungsradius jedes Mal neu vorgenommen werden.In order not to have to provide a separate sanding shoe for every possible profile shape, a continuously adjustable belt sanding device is known (AT 413 958 B) with mutually displaceable lamellas, which form a profiled surface by pressing against a corresponding pattern against the resistance of an elastic material adjust and fix 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. 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 Her- stellen 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. Diese Aufgaben werden erfindungsgemäß dadurch gelöst, daß das Schleifmodul an dem Grundkörper mittig um einen Achsbolzen drehbar gelagert angeordnet ist und an seinem Umfangsprofil wenigstens zwei Viertelkreiskonturen mit unterschiedlichen Radien aufweist, welche die jeweilige Führungsfläche für das Schleifband bestimmen.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. 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 each set to a certain radius of a sanded rounded edge and thus made the manufacture of the imaged by the tool profile properly can, where the transitions between the arc surface and adjoining flat surfaces are to be polished clean and these settings should be reproducible at any time. These objects are inventively achieved in that the grinding module is arranged centrally rotatably mounted on the base body about a pivot pin and at its peripheral profile has at least two quadrant contours with different radii, which determine the respective guide surface for the grinding belt.
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, via which it in the respective radius of curvature corresponding position by means of an index pin and a locking screw is fixed.
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 Schleif - bandrücken 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 zu- geschnittener Gleitbelag angebracht werden, dessen Dicke, ebenso wie jene des Schleifbandes, bei der Ausbildung der Rundungsprofile zu berücksichtigen ist.In order to reduce the friction between the guide surface of the disk-shaped grinding module and the belt guide jaws and the grinding belt back produced by the rapidly rotating grinding belt, it is expedient if, according to the invention, a sliding lining is provided between the grinding module and the belt guiding elements on the one hand and the grinding belt on the other hand. For example, an existing from a textile substrate with applied graphite layer and correspondingly cut cut sliding, whose thickness, 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 Bandschleifaggre- gat 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 ei- nem Winkel von 45° und im entsprechendem Abstand gegen die Werkstückkante weist. - A -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 is fixedly screwed to the machine by a connecting part between the sanding belt deflection rollers to be attached to the base body such that the center axis of the belt grinding device aligned along the workpiece transport direction is at an angle of 45 ° and at the appropriate distance against the edge of the workpiece. - A -

Ein erfindungsgemäßes Bandschleifwerkzeug 1 mit einem umlaufenden Schleifband 11 umfaßt einen Grundkörper 3, welcher an einem feststehenden Achsbolzen 5, ein daran drehbar gelagertes, scheibenförmiges Schleifmodul 4, dessen Umfangskontur beim gezeigten Beispiel symmetrisch angeordnet acht verschiedene Konturen in Viertelkreisform aufweist, welche die Führungsflächen zur Abstützung des Schleifbandes 11 zusammen mit den im Grundkörper 3 zwischen der Profilscheibe 4 und der Deckplatte 13 geführten und mit Hilfe von Einstellschrauben 10 und 10a verstellbaren Bandführungselemente 9 und 9a unter Zwischenlage eines Gleitbelages 12 im Schleifbereich an einem möglichen Werkstück 2 bilden. 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. 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. 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.An inventive belt grinding tool 1 with a revolving belt 11 comprises a base body 3, which on a fixed axle 5, a rotatably mounted thereon, disc-shaped grinding module 4, the circumferential contour symmetrically arranged in the example shown eight different contours in a quarter circle, which the guide surfaces for supporting the Sanding belt 11 together with the guided in the base body 3 between the profile disk 4 and the cover plate 13 and adjustable by means of adjusting screws 10 and 10a band guide elements 9 and 9a with the interposition of a sliding coating 12 in the grinding area on a possible workpiece 2. 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. The adjustment to a different rounding contour or a different radius of curvature is achieved by loosening the locking screw 6, removing the grinding module 4 on the axle pin 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 shows in plan view A of Fig. 1 schematically the possible installation arrangement of a belt grinding tool 1 according to the invention in a symbolically represented by the sanding belt rollers 14, 15 and 16 and a rotating grinding belt 11 grinding unit, wherein a grinding process performed on a workpiece 2 guided along it becomes.
