Definitions
- the invention relates to a rotating machine grinding tool, the working surface of which is equipped with an abrasive, in particular a bonded abrasive cloth, and the abrasive provided therefor.
- Rotating machine grinding tools with which grinding is carried out on an industrial scale, in particular in the furniture industry, can be divided into types of rotating grinding belts and rotating grinding wheels or rollers.
- the working surfaces of the grinding tools that can be brought into contact with the workpiece to be ground are equipped with abrasive abrasives.
- Such abrasives consist of a base made of paper, tissue or the like, the surface of which is provided with a layer of abrasive grains. Most of the time, it is about abrasive cloth glued to the work surfaces, which, due to its relatively short service life, must be replaced regularly by loosening the bond and then gluing new abrasive cloth on.
- the working surfaces of the grinding tools are contoured accordingly for grinding profiles.
- the glued abrasive cloth is thin enough to be nestled into the contours. It has been shown that during profile grinding, point abutments of the abrasive can result on the profile to be ground, as a result of which undesirable "chatter marks" occur in the surface of the workpiece to be ground.
- the point support can locally lead to such high pressure that the frictional heat that occurs leads to "burning" of the abrasive. About that In addition, intermediate lacquer sanding with abrasive cloth is not possible because the lacquer layer is sanded through.
- the invention has for its object to provide a rotating machine grinding tool and an abrasive provided for its equipment, in which the disadvantages described above do not occur.
- This object is achieved in that an elastic pad is arranged between the work surface and the abrasive cloth.
- an abrasive tool equipped in this way has the advantage that the relatively soft pad is protected under the abrasive cloth so that pieces are not torn out.
- the mechanical strength of the abrasive cloth covering the pad prevents instability due to centrifugal forces.
- a suitable foam with appropriate porosity and elasticity can therefore be selected for the upholstery.
- a grinding tool for example a rotating grinding wheel, can first be covered with a foam pad on its work surface in preparation for the grinding process. An abrasive cloth is then placed over it, covering the free surface of the foam pad.
- the pad can be glued to the work surface, whereby the abrasive cloth can in turn be glued to the pad.
- contoured work surfaces of grinding tools can also be equipped for profile grinding.
- the abrasive cloth and pad can be in the form of strips that are only cut to the appropriate length.
- the abrasive cloth strip is particularly advantageously wider than the upholstery strip. This makes it possible to pull the longitudinal edges of the abrasive cloth strip over the longitudinal edges of the padded strip and to attach them to the grinding tool, for example a rotating grinding wheel, by gluing.
- the pad is completely encapsulated under the abrasive cloth and protected against mechanical influences.
- An embodiment of the abrasive, with which a grinding tool can be equipped in the manner according to the invention, and for which independent protection is also claimed, provides that a central region of the abrasive cloth strip is coated with a cushioning strip.
- Appropriate prefabrication can thus be used to provide a one-piece abrasive consisting of upholstery and abrasive cloth, which is in the form of strips or strips. Sections of appropriate length can be cut from the abrasive strip with which the working surfaces of an abrasive tool can be equipped.
- At least one of the longitudinal edges of the abrasive strip has notches. Both longitudinal edges of the abrasive strip are preferably provided with corresponding notches, which facilitate nestling of the abrasive strip into corresponding contours in the working surface of an abrasive tool.
- the notches are attached in such a way that they protrude at least partially into the adjacent edge of the cushion strip.
- the padding strip on the underside of the loop This does not hinder the deformations necessary for nestling into the contours of the work surface.
- the notches can be simple, more or less acute-angled incisions.
- the notches are preferably designed as a row of holes running parallel to the respective longitudinal edge of the abrasive, a longitudinal edge incision being made in each hole.
- the pad strip can be attached to the underside of the abrasive cloth strip using appropriate means, for example adhesives.
- the undersides of the abrasive cloth strip and the cushion strip arranged on the work surface have a coating of adhesive that can be activated by preferably dissolving.
- the grinding tool has a tool body 2 with a work surface 3 that can be pressed against a workpiece (not shown here).
- the work surface 3 is covered with a foam pad 4.
- Abrasive cloth 5 is placed over the upholstery is wider than the pad 4, so that its longitudinal edges 6 and 7 can be folded down, pulled over the side edges of the pad 4 and can be attached to the flank surfaces 8 and 9 of the tool body 2, for example by gluing.
- the pad 4 is thus protected under the abrasive cloth 5, which is relatively resistant to mechanical loads.
- the pad 4 can also be glued to the work surface 3. Furthermore, it is possible to glue the abrasive cloth over the entire surface with the facing top of the cushion 4.
- Fig. 2 shows a bottom view of an abrasive which is prefabricated in the form of a strip, a portion of which is shown here.
- the abrasive consists of the abrasive cloth strips 5, the central strip area of which is coated with a strip of cushion 4. Since the abrasive cloth strip 5 is wider than the upholstery strip 4, only the protruding longitudinal edges 6 and 7 are visible here, the longitudinal edges of the upholstery strip 4 being designated 10 and 11.
- Notches 12 denote notches which are designed as a row of holes running parallel to the respective longitudinal edge 6, 7, a longitudinal edge incision 13 being made in each hole.
- Fig. 3 shows a sectional view of the abrasive along the line III - III in Fig. 2. Under the abrasive cloth strips 5, the pad 4 is glued. The longitudinal edges of the abrasive cloth strip 5 are again designated 6 and 7, it being clearly visible here that the abrasive cloth 5 is wider than the cushion 4. As in FIG. 2, it can also be seen in FIG. 3 that the notches formed as a row of holes partially extend into the upholstery strip 4.
- the undersides of the abrasive cloth strip 5 and the arranged cushion strip 4, which come to rest on the work surface 3 (FIG. 1), are provided with a coating 14 made of, for example, adhesives which can be activated by detachment.

Abstract
Description
Die Erfindung betrifft ein umlaufendes Maschinen-Schleifwerkzeug, dessen Arbeitsfläche mit einem Schleifmittel, insbesondere einem aufgeklebten Schleifleinen, ausgerüstet ist, sowie das dafür vorgesehende Schleifmittel.The invention relates to a rotating machine grinding tool, the working surface of which is equipped with an abrasive, in particular a bonded abrasive cloth, and the abrasive provided therefor.
Umlaufende Maschinen-Schleifwerkzeuge mit denen im industriellen Maßstab, insbesondere in der Möbelindustrie, geschliffen wird, sind gattungsmäßig unterteilbar in umlaufende Schleifgurte und rotierende Schleifscheiben bzw. Walzen. Die mit dem zu schleifenden Werkstück in Anlage bringbaren Arbeitsflächen der Schleifwerkzeuge sind mit abrasivem Schleifmittel ausgerüstet. Derartige Schleifmittel bestehen aus einer Unterlage aus Papier, Gewebe oder dergleichen, deren eine Oberfläche mit einer Schicht aus abrasiv wirkenden Körnern versehen ist. Zumeist handelt es sich um auf die Arbeitsflächen geklebtes Schleifleinen, das auf Grund relativ kurzer Standzeiten regelmäßig zu erneuern ist, indem die Klebung gelöst und danach neues Schleifleinen aufgeklebt wird.Rotating machine grinding tools with which grinding is carried out on an industrial scale, in particular in the furniture industry, can be divided into types of rotating grinding belts and rotating grinding wheels or rollers. The working surfaces of the grinding tools that can be brought into contact with the workpiece to be ground are equipped with abrasive abrasives. Such abrasives consist of a base made of paper, tissue or the like, the surface of which is provided with a layer of abrasive grains. Most of the time, it is about abrasive cloth glued to the work surfaces, which, due to its relatively short service life, must be replaced regularly by loosening the bond and then gluing new abrasive cloth on.
Für das Schleifen von Profilen sind die Arbeitsflächen der Schleifwerkzeuge entsprechend konturiert. Das aufgeklebte Schleifleinen ist ausreichend dünn, um in die Konturen eingeschmiegt zu werden. Es hat sich gezeigt, daß sich beim Profilschleifen Punktauflagen des Schleifmittels an dem zu schleifenden Profil ergeben können, wodurch unerwünschte "Rattermarken" in der Oberfläche des zu schleifenden Werkstücks auftreten. Außerdem kann die Punktauflage unter Umständen örtlich zu so hohem Andruck führen, daß auftretende Reibungswärme zum "Brennen" des Schleifmittels führt. Darüber hinaus ist ein Lackzwischenschliff mit Schleifleinen nicht möglich, da die Lackschicht durchgeschliffen wird.The working surfaces of the grinding tools are contoured accordingly for grinding profiles. The glued abrasive cloth is thin enough to be nestled into the contours. It has been shown that during profile grinding, point abutments of the abrasive can result on the profile to be ground, as a result of which undesirable "chatter marks" occur in the surface of the workpiece to be ground. In addition, the point support can locally lead to such high pressure that the frictional heat that occurs leads to "burning" of the abrasive. About that In addition, intermediate lacquer sanding with abrasive cloth is not possible because the lacquer layer is sanded through.
Zur Überwindung dieser Nachteile ist bereits vorgeschlagen worden, Schleifleinen durch einen Schaumstoffstreifen zu ersetzen, in dessen mit dem Werkstück in Anlage zu bringende schleifende Oberfläche entsprechend körniges Schleifmaterial eingebunden ist. Ein derartiger Schaumstoffstreifen als Schleifmittel läßt sich jedoch nur für den Lackzwischenschliff einsetzen. Für den Holzschliff ist das zu erreichende Schleifen nicht aggressiv genug. Darüber hinaus hat sich insbesondere bei rotierenden Schleifwerkzeugen gezeigt, daß sich bei Drehzahlen über 1200/min der Kern des Schaumstoffstreifens durch Fliehkräfte reckt und das Schleifmittel dadurch instabil wird. Wesentlicher Nachteil ist auch, daß das zu schleifende Werkstück das aus Schaumstoff gebildete Schleifmittel aufgrund des Schleifandrucks walkt, wodurch sich an der schleifenden Oberfläche die Kornbindung des abrasiven Materials lockert und ein Abblättern auftritt.To overcome these disadvantages, it has already been proposed to replace abrasive lines with a foam strip, in whose corresponding abrasive surface to be brought into contact with the workpiece is grained abrasive material. Such a foam strip as an abrasive can only be used for intermediate sanding. The sanding to be achieved is not aggressive enough for sanding wood. In addition, it has been shown in particular in the case of rotating grinding tools that the core of the foam strip stretches due to centrifugal forces at speeds above 1200 rpm and the abrasive thereby becomes unstable. Another major disadvantage is that the workpiece to be ground rolls the abrasive formed from foam due to the abrasive pressure, which loosens the grain bond of the abrasive material on the abrasive surface and flaking occurs.
Es ist auch möglich, daß Ecken des Werkstücks in das weichelastische Schleifmittel einstechen, wodurch Stücke herausgerissen werden können. Das Ein- und Aussetzen des Schleifwerkzeugs erfordert deshalb hohen technischen Aufwand an entsprechenden Aggregaten und Maschinen.It is also possible for corners of the workpiece to penetrate the flexible elastic abrasive, as a result of which pieces can be torn out. The insertion and removal of the grinding tool therefore requires a great deal of technical effort on the corresponding units and machines.
Der Erfindung liegt die Aufgabe zugrunde, ein umlaufendes Maschinen-Schleifwerkzeug zu schaffen sowie ein für dessen Ausrüstung vorgesehenes Schleifmittel, bei dem die vorbeschriebenen Nachteile nicht auftreten.The invention has for its object to provide a rotating machine grinding tool and an abrasive provided for its equipment, in which the disadvantages described above do not occur.
Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß zwischen der Arbeitsfläche und dem Schleifleinen ein elastisches Polster angeordnet ist.This object is achieved in that an elastic pad is arranged between the work surface and the abrasive cloth.
Mit dem erfindungsgemäßen Schleifwerkzeug kann, wie mit einem Schleifleinen, relativ aggressiv geschliffen werden, wobei auf Grund der Unterfütterung des Schleifleinens mit einem elastischen Polster dessen Nachteile nicht auftreten. Beim Schleifen mit dem erfindungsgemäßen Schleifwerkzeug treten "Rattermarken" nicht auf und das Schleifmittel kann auch nicht brennen; denn es baut sich keine Reibungswärme auf, weil der Schleifandruck gleichmäßig ist. Das Schleifwerkzeug eignet sich dadurch vorteilhaft zum Schleifen von Profilen, da eine großflächige Schleifmittelauflage auf dem Werkstück gegeben ist. In vorteilhafter Weise werden größere Formabweichungen und Maßtoleranzen dabei ausgeglichen.With the grinding tool according to the invention, as with a Abrasive cloths are sanded relatively aggressively, whereby the disadvantages do not occur due to the padding of the sanding cloth with an elastic pad. "Chatter marks" do not occur when grinding with the grinding tool according to the invention and the abrasive cannot burn; because no frictional heat builds up because the grinding pressure is even. The grinding tool is therefore advantageously suitable for grinding profiles, since there is a large-area abrasive support on the workpiece. Larger deviations in shape and dimensional tolerances are advantageously compensated for.
Gegenüber dem nur für den Lackzwischenschliff geeigneten, ein Schaumstoffband mit an einer Oberfläche eingebundenen abrasiven Körnern umfassenden Schleifmittel, hat ein derart ausgerüstetes Schleifwerkzeug den Vorteil, daß das relativ weiche Polster unter dem Schleifleinen geschützt liegt, so daß ein Herausreißen von Stücken nicht auftritt. Instabilität durch Fliehkräfte wird durch die mechanische Festigkeit des das Polster abdeckenden Schleifleinens verhindert.Compared to the abrasive, which is only suitable for intermediate varnish sanding and comprises a foam tape with abrasive grains bound to a surface, an abrasive tool equipped in this way has the advantage that the relatively soft pad is protected under the abrasive cloth so that pieces are not torn out. The mechanical strength of the abrasive cloth covering the pad prevents instability due to centrifugal forces.
Für das Polster kann deshalb ein geeigneter Schaumstoff mit entsprechender Porigkeit und Elastizität gewählt werden.A suitable foam with appropriate porosity and elasticity can therefore be selected for the upholstery.
Ein Schleifwerkzeug, beispielsweise eine rotierende Schleifscheibe, kann in Vorbereitung des Schleifvorganges an seiner Arbeitsfläche zunächst mit einem Polster aus Schaumstoff belegt werden. Darüber wird dann ein Schleifleinen gelegt, das die freie Oberfläche des Schaumstoff-Polsters abdeckt.A grinding tool, for example a rotating grinding wheel, can first be covered with a foam pad on its work surface in preparation for the grinding process. An abrasive cloth is then placed over it, covering the free surface of the foam pad.
Das Polster kann auf die Arbeitsfläche geklebt sein, wobei das Schleifleinen wiederum auf das Polster geklebt werden kann. Auf diese Weise lassen sich ohne weiteres auch konturierte Arbeitsflächen von Schleifwerkzeugen für das Profileschleifen ausrüsten.The pad can be glued to the work surface, whereby the abrasive cloth can in turn be glued to the pad. In this way, contoured work surfaces of grinding tools can also be equipped for profile grinding.
Das Schleifleinen und das Polster können in Form von Streifen vorliegen, die lediglich auf entsprechende Länge geschnitten werden.The abrasive cloth and pad can be in the form of strips that are only cut to the appropriate length.
Der Schleifleinen-Streifen ist mit besonderem Vorteil breiter als der Polster-Streifen. Dies ermöglicht, die Längsränder des Schleifleinen-Streifens über die Längsränder des Polster-Streifens zu ziehen und an dem Schleifwerkzeug, beispielsweise einer rotierenden Schleifscheibe, durch Verkleben zu befestigen. Das Polster ist dadurch unter dem Schleifleinen vollständig gekapselt und gegen mechanische Einwirkungen geschützt.The abrasive cloth strip is particularly advantageously wider than the upholstery strip. This makes it possible to pull the longitudinal edges of the abrasive cloth strip over the longitudinal edges of the padded strip and to attach them to the grinding tool, for example a rotating grinding wheel, by gluing. The pad is completely encapsulated under the abrasive cloth and protected against mechanical influences.
Eine Ausgestaltung des Schleifmittels, mit dem sich ein Schleifwerkzeug in erfindungsgemäßer Weise ausrüsten läßt, und für die auch selbständiger Schutz beansprucht wird, sieht vor, daß ein Streifenmittelbereich des Schleifleinen-Streifens mit einem Polster-Streifen beschichtet ist. Durch entsprechende Vorfabrikation kann somit ein aus Polster und Schleifleinen bestehendes einstückiges Schleifmittel bereitgestellt werden, das in Streifen oder Bandform vorliegt. Von dem Schleifmittelstreifen können Abschnitte entsprechender Länge geschnitten werden, mit denen sich die Arbeitsflächen eines Schleifwerkzeugs ausrüsten lassen.An embodiment of the abrasive, with which a grinding tool can be equipped in the manner according to the invention, and for which independent protection is also claimed, provides that a central region of the abrasive cloth strip is coated with a cushioning strip. Appropriate prefabrication can thus be used to provide a one-piece abrasive consisting of upholstery and abrasive cloth, which is in the form of strips or strips. Sections of appropriate length can be cut from the abrasive strip with which the working surfaces of an abrasive tool can be equipped.
Damit die Ausrüstung auch von konturierten Arbeitsflächen problemlos möglich ist, weist wenigstens einer der Längsränder des Schleifmittelstreifens Ausklinkungen auf. Vorzugsweise sind beide Längsränder des Schleifmittelstreifens mit entsprechenden Ausklinkungen versehen, die ein Einschmiegen des Schleifmittelstreifens in entsprechende Konturen in der Arbeitsfläche eines Schleifwerkzeugs erleichtern. Dabei sind die Ausklinkungen so angebracht, daß sie zumindest teilweise in den jeweils benachbarten Rand des Polster-Streifens hineinragen. Der Polster-Streifen an der Unterseite des Schleifleinens behindert dadurch nicht die für das Anschmiegen in die Konturen der Arbeitsfläche notwendigen Verformungen.So that the equipment of contoured work surfaces is possible without any problems, at least one of the longitudinal edges of the abrasive strip has notches. Both longitudinal edges of the abrasive strip are preferably provided with corresponding notches, which facilitate nestling of the abrasive strip into corresponding contours in the working surface of an abrasive tool. The notches are attached in such a way that they protrude at least partially into the adjacent edge of the cushion strip. The padding strip on the underside of the loop This does not hinder the deformations necessary for nestling into the contours of the work surface.
Die Ausklinkungen können einfache, mehr oder weniger spitzwinkelige Einschnitte sein. Vorzugsweise sind die Ausklinkungen als parallel zum jeweiligen Längsrand des Schleifmittels verlaufende Lochreihe ausgebildet, wobei in jedes Loch ein Längsrandeinschnitt geführt ist.The notches can be simple, more or less acute-angled incisions. The notches are preferably designed as a row of holes running parallel to the respective longitudinal edge of the abrasive, a longitudinal edge incision being made in each hole.
Der Polster-Streifen kann an der Unterseite des Schleifleinen-Streifens mit entsprechenden Mitteln, beispielsweise Klebstoffen, befestigt werden.The pad strip can be attached to the underside of the abrasive cloth strip using appropriate means, for example adhesives.
Um das erfindungsgemäße Schleifmittel an einem Schleifwerkzeug befestigen zu können, weisen die an der Arbeitsfläche zu Liegen kommenden Unterseiten des Schleifleinen-Streifen sowie des daran angeordneten Polster-Streifens eine Beschichtung aus durch vorzugsweise Anlösen aktivierbarem Klebemittel auf.In order to be able to fasten the abrasive according to the invention to a grinding tool, the undersides of the abrasive cloth strip and the cushion strip arranged on the work surface have a coating of adhesive that can be activated by preferably dissolving.
