Description

Die Erfindung betrifft ein Werkzeug, mit dem Klebstoffreste, Folien, Überzüge oder dergleichen von Unterlagen, insbesondere Metalloberflächen, entfernt werden können.The invention relates to a tool with which adhesive residues, Films, covers or the like of documents, in particular Metal surfaces can be removed.

Es ist bereits ein solches Werkzeug bekannt (US-PS 5259914), bei dem ein Werkzeugschaft mit einer flachen Metallscheibe verschraubt ist. Die Scheibe weist Umfangskerben auf und wird in eine flache aus einem weichen Kunststoff bestehende Scheibe eingebettet. Die Kerben sind erforderlich, damit der weiche Kunststoff beim Drehantrieb mitgenommen wird. Die metallische Scheibe ist allseits von dem weichen Kunststoff umgeben. Das Werkzeug wird in einen Drehantrieb eingespannt und so benutzt, daß die Mantelfläche der weichen Gummischeibe gegen die Oberfläche mit dem zu entfernten Material angedrückt wird. Es erfolgt eine Erwärmung und dadurch eine Ablösung des Materials. Dabei nutzt sich die Gummischeibe ab.Such a tool is already known (US-PS 5259914), where a tool shank with a flat metal disc is screwed. The disc has circumferential notches and is in a flat one made of a soft plastic Disc embedded. The notches are required for the soft plastic is taken with the rotary drive. The metallic disc is on all sides of the soft plastic surround. The tool is clamped in a rotary drive and used so that the outer surface of the soft rubber washer pressed against the surface with the material to be removed becomes. It heats up and thereby detaches of the material. The rubber washer wears out.

Bei weichen anzutreibenden Bearbeitungsscheiben können Lösungen, wie sie bei starren Schleifscheiben verwendet werden, keine Anwendung finden. Es besteht sonst die Gefahr, daß die Scheibe nachgibt und kein Drehantrieb mehr erfolgt.With soft processing discs to be driven Solutions used in rigid grinding wheels will not apply. Otherwise there is a risk that the disc gives way and there is no more rotary drive.

Der Erfindung liegt die Aufgabe zugrunde, ein Werkzeug der eingangs genannten Art zu schaffen, das sich leichter herstellen läßt.The invention has for its object a tool to create the type mentioned above, which is easier to manufacture leaves.

Zur Lösung dieser Aufgabe schlägt die Erfindung eine Werkzeug mit dem im Schutzanspruch 1 genannten Merkmalen vor. Weiterbildungen der Erfindung sind Gegenstand von Unteransprüchen.To achieve this object, the invention proposes a tool with the features mentioned in protection claim 1. Training the invention are the subject of dependent claims.

Das Werkzeug nach der Erfindung hat den Vorteil, daß keine Einbettung eines metallischen Teiles in die flache Scheibe mehr erfolgen muß. Daher kann die sich beim Gebrauch des Werkzeugs abnutzende Gummischeibe getrennt hergestellt und anschließend mit dem Schaft und dem Spannmittel verbunden werden. Nach Abnutzung kann auch ein Austausch der Gummischeibe erfolgen.The tool according to the invention has the advantage that none Embedding a metallic part in the flat pane more must be done. Therefore, when using the Tool wearing rubber washer manufactured separately and then connected to the shaft and the clamping device become. After wear, the rubber washer can also be replaced respectively.

Insbesondere kann vorgesehen sein, daß die Scheibe eine zentrale, von einer Flachseite zu der anderen Flachseite durchgehende Öffnung aufweist, durch die hindurch das Spannmittel mit dem Schaft verbindbar ist. Diese zentrale Öffnung kann bei Herstellung der Scheibe in sehr einfacher Weise hergestellt werden.In particular, it can be provided that the disk has a central, continuous from one flat side to the other flat side Has opening through which the clamping means is connectable to the shaft. This central opening can manufactured in a very simple manner in the manufacture of the disc become.

Die Drehmitnahme zwischen dem Schaft und der Scheibe kann beispielsweise dadurch geschehen, daß das Spannmittel fest gegen den Schaft unter Zwischenlage des mittleren Teiles der Scheibe verspannt wird. Beispielsweise ist es auch denkbar, daß der Schaft und das Spannmittel mit den Flachseiten der Scheibe in deren zentralem Bereich verklebt werden. The rotation between the shaft and the disc can happen, for example, that the clamping means firmly against the shaft with the intermediate part of the middle Disc is clamped. For example, it is also conceivable that the shaft and the clamping device with the flat sides of the Glue the pane in the central area.

Insbesondere wird jedoch von der Erfindung vorgeschlagen, die Öffnung der Scheibe so auszubilden, daß diese von der Kreisform abweicht.In particular, however, the invention proposes that Form the opening of the disc so that it is circular deviates.

Es kann ebenfalls vorgesehen sein, daß der durch die Öffnung der Scheibe hindurchgreifende Teil des Spannmittels und/oder des Schaftes von der Kreisform abweicht, insbesondere eine der Öffnung der Scheibe entsprechender Form aufweisen kann. In diesem Fall wird also in Drehrichtung des Werkzeugs ein Formschluß zwischen dem Schaft und dem Spannmittel einerseits und der weichen Scheibe andererseits hergestellt. Dies führt zu einem verbesserten Mitnehmen der Scheibe beim Drehantrieb.It can also be provided that through the opening part of the clamping means reaching through the disc and / or of the shaft deviates from the circular shape, in particular one the opening of the disc can have a corresponding shape. In this case, the tool turns in the direction of rotation Form fit between the shaft and the clamping device on the one hand and the soft disk on the other hand. this leads to for an improved driving of the disc with the rotary drive.

In nochmaliger Weiterbildung der Erfindung kann vorgesehen sein, daß der Schaft eine senkrecht zu seiner Drehachse verlaufende Anlagefläche aufweist, gegen die die Scheibe verspannt wird. Diese Anlagefläche vergrößert die Berührungsflächen zwischen dem Schaft und der weichen Scheibe, was ebenfalls eine Übertragung des Drehmoments beim Antrieb verbessert.In a further development of the invention can be provided be that the shaft is perpendicular to its axis of rotation Has contact surface against which the disc braced becomes. This contact area increases the contact areas between the shaft and the soft disc what transmission of the torque when driving is also improved.

Es kann in Weiterbildung ebenfalls vorgesehen sein, daß auch das Spannmittel eine senkrecht zur Drehachse des Werkzeugs verlaufende Anlagefläche aufweist, gegen die die Scheibe verspannt.In training it can also be provided that the clamping device is perpendicular to the axis of rotation of the tool has running contact surface against which the disc braces.

Insbesondere kann vorgesehen sein, daß das Spannmittel eine Spannscheibe aufweist, deren eine Seite die Anlagefläche bildet. Die weiche Scheibe wird dann zwischen den beiden Anlageflächen eingespannt.In particular, it can be provided that the clamping means a Has spring washer, one side of which forms the contact surface. The soft disc is then between the two contact surfaces clamped.

Die Spannscheibe kann in Weiterbildung mit dem Schaft verschraubt werden. Hierzu kann es vorgesehen sein, daß die Schraube einstückig an der Spannscheibe ausgebildet wird, anders ausgedrückt, daß eine Schraube mit einem in radialer Hinsicht sehr großen Kopf verwendet wird.In a further development, the tensioning disk can be screwed to the shaft become. For this purpose, it can be provided that the Screw is integrally formed on the tensioning washer, in other words, a screw with a radial one Respect very large head is used.

Andererseits ist es auch möglich, eine getrennte Schraube zu verwenden, die durch eine Öffnung in der Spannscheibe hindurch greift. Insbesondere kommt eine Senkkopfschraube in Frage.On the other hand, it is also possible to tighten a separate screw use that through an opening in the spring washer takes hold. In particular, a countersunk screw comes in Question.

Es ist natürlich auch möglich, daß der Schaft einen Gewindeabschnitt aufweist, auf denen die Spannscheibe aufgeschraubt wird.It is of course also possible for the shaft to have a threaded section has, on which the tension disc is screwed becomes.

Insbesondere kann die Öffnung der Scheibe und/oder der durch die Öffnung hindurchgreifende Teil des Spannmittels und/oder des Schaftes die Form eines Flügelrads bzw. eines mehrstrahligen Sterns aufweisen.In particular, the opening of the disc and / or through part of the clamping means reaching through the opening and / or the shaft has the shape of an impeller or a multi-jet Have a star.

Es sind auch andere Arten der Aufnahme des Schaftes 1 möglich. An den glatten zylindrischen Schaftabschnitt 2 schließt sich eine flachkegelige Scheibe 3 an, die auf der dem Abschnitt 2 abgewandten Seite 4 eben ausgebildet ist. An die ebene Flachseite 4 schließt sich ein Abschnitt 5 des Schaftes 1 an, der die Form eines Flügelrads mit drei Flügeln aufweist. Dieser Abschnitt 5 des Werkzeugschaft 1 greift durch eine gleich geformte Öffnung 6 der aus weichem Gummi bestehenden Scheibe 7 hindurch. Die Scheibe 7 liegt mit ihrer einen Flachseite 8 auf der ebenen Flachseite 4 der flachkegeligen Scheibe 3 auf. Mit dem freien Ende des Abschnitts 5 ist ein Spannmittel 9 verschraubt, das eine flache, insbesondere metallische Scheibe 10 enthält. Die metallische Scheibe 10 enthält eine zentrale Bohrung, durch die eine Schraube 11 hindurch greift. Die Schraube 11 ist in eine zentrale Gewindebohrung 12 des Schaftes 1 eingeschraubt. Durch Festziehen der Schraube 11 wird die Spannscheibe 10 gegen die in Figur 1 obere Flachseite 18 der weichen Scheibe 7 verspannt. Durch das Anziehen der Schraube 11 wird also die Scheibe 7 zwischen der Fläche 4 des Werkzeugschafts 1 und der Spannscheibe 10 eingespannt.Figure 1 shows a view of the tool in which the soft rubber existing disc is cut. The tool contains a shaft 1, which on its one in Fig. 1st lower free end of a smooth cylindrical shaft portion 2 has. With this shaft section 2 Shank 1 of the tool used in a drive device be, for example, a drill or a screwdriver. There are also other ways of receiving the shaft 1 possible. On the smooth cylindrical shaft section 2 is followed by a flat-tapered disc 3, which on the side 4 facing away from section 2 is flat. On the flat flat side 4 closes a section 5 of the Shaft 1, which has the shape of an impeller with three blades having. This section 5 of the tool shank 1 engages through an equally shaped opening 6 made of soft rubber existing disc 7 through. The disc 7 is with her a flat side 8 on the flat flat side 4 of the flat-cone Disc 3 on. With the free end of section 5 is a clamping means 9 screwed, which is a flat, in particular contains metallic disc 10. The metallic disc 10 contains a central hole through which a screw 11 reaches through. The screw 11 is in a central threaded hole 12 of the shaft 1 screwed. By tightening the screw 11, the clamping disk 10 against the in Figure 1 upper flat side 18 of the soft disc 7 clamped. By tightening the screw 11 will thus the disc 7 between the surface 4 of the tool shank 1 and the clamping disk 10 clamped.

Figur 2 zeigt in dem Querschnitt durch das Werkzeug der Figur 1 die Form des Abschnitts 5 des Werkzeugschaftes mit den drei Flügeln 13 des in Form eines Flügelrads ausgebildeten Abschnitts 5 des Werkzeugschafts. Die Öffnung 6 weist die gleiche Form auf, so daß der Abschnitt 5 mit seinen drei Flügeln 13 in die entsprechenden radial verlaufenden Teile der Öffnung 6 der Scheibe 7 eingreift. Dadurch ist eine gute Möglichkeit der Mitnahme der Scheibe 7 gegeben.Figure 2 shows in cross section through the tool of the figure 1 the shape of section 5 of the tool shank with the three Wings 13 of the section in the form of an impeller 5 of the tool shank. The opening 6 has the same Form on so that section 5 with its three wings 13 in the corresponding radially extending parts of the opening 6 engages the disc 7. This is a great way given the taking of the disc 7.

Diese Einzelheiten ergeben sich auch aus der Figur 3. Figur 3 zeigt den Werkzeugschaft 1 aus der gleichen Richtung wie in Figur 1. Zwei der Flügel 13 sind rechts und links zu sehen, während der dritte Flügel im Stirnansicht dargestellt ist. Die Schraube 11, im dargestellten Beispiel eine Senkkopfschraube, wird durch die zentrale Öffnung der Spannscheibe 10 hindurchgesteckt und in die in der Drehachse liegende Gewindebohrung 12 eingeschraubt.These details also result from FIG. 3. FIG. 3 shows the tool shank 1 from the same direction as in Figure 1. Two of the wings 13 can be seen on the right and left, while the third wing is shown in the front view. The screw 11, in the example shown a countersunk screw, is through the central opening of the spring washer 10th inserted and into the threaded hole in the axis of rotation 12 screwed in.

Die Figur 4 zeigt eine Aufsicht auf den Werkzeugschaft, in Figur 3 von oben. Die drei Flügel 13, die sich von dem die Gewindebohrung 12 enthaltenden Kern des Abschnitts 5 radial nach außen erstrecken, sind gleichmäßig über den Umfang verteilt. Sie reichen nicht ganz bis zum Umfang der ebenen Flachseite 4.FIG. 4 shows a top view of the tool shank, in Figure 3 from above. The three wings 13, which differ from the Threaded bore 12 containing the core of section 5 radially extend outwards, are evenly distributed over the circumference. They do not quite reach the level of the levels Flat side 4.

Bei dem dargestellten Werkzeug sind die Flügel 13 des Abschnitts 5 an dem Werkzeugschaft angeordnet. Es ist selbstverständlich auch möglich, den Abschnitt 5 mit den Flügeln 13 an dem Spannmittel 9 auszubilden und dieses dann mit der Scheibe 3 des Werkzeugschafts 1 zu verschrauben. Ebenfalls möglich ist es, daß der die Flügel 13 aufweisende Kern des Schaftes 1 nicht hohl ist, sondern ein mit einem Außengewinde versehenes zapfenartiges Ende aufweist, das dann in die zentrale mit einem Gewinde versehene Öffnung der Spannscheibe 10 eingeschraubt wird.In the illustrated tool, the wings 13 of the section 5 arranged on the tool shank. It goes without saying also possible section 5 with wings 13 form on the clamping means 9 and then this with the Screw disc 3 of tool shank 1. Likewise it is possible that the core 13 having the wing 13 Shaft 1 is not hollow, but one with an external thread provided provided pin-like end, which then in the central threaded opening of the tension washer 10 is screwed in.

Der Werkzeugschaft 1 und das Spannmittel 9 sind im dargestellten Beispiel als aus Metall bestehend bezeichnet. Es kommt hier natürlich auch ein Kunststoff in Frage, bei dem es sich jedoch um einen Kunststoff handeln müßte, der relativ hart ist, damit die Übertragung des Drehmoments von der Antriebseinrichtung erfolgen kann.The tool shank 1 and the clamping means 9 are shown in the Example referred to as consisting of metal. It here, of course, a plastic comes into question, where it however, it would have to be a plastic that is relative is hard so the transmission of the torque from the drive device can be done.
