Abstract
Description
Die Erfindung betrifft ein Schleifmittel ausgebildet in Form eines Streifens aus Schleifleinen, zur Ausrüstung der Arbeitsfläche eines umlaufenden Maschinen-Schleifwerkzeugs.The invention relates to an abrasive formed in Form of a strip of abrasive cloth, for Equipping the work surface of a rotating machine grinding tool.
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 aufgrund relativ kurzer Standzeiten regelmäßig zu erneuern ist, indem die Klebung gelöst und danach neues Schleifleinen aufgeklebt wird.Rotating machine grinding tools with those in the industrial scale, especially in the furniture industry, is ground, can be divided into genres all-round grinding belts and rotating grinding wheels or Rollers. The system with the workpiece to be ground bring work surfaces of the grinding tools with abrasive abrasive. Such abrasives consist of a base of paper, tissue or the like, one surface of which is made of a layer abrasive grains. Mostly it is around abrasive cloth glued to the work surfaces, the to be renewed regularly due to relatively short downtimes is by loosening the glue and then new abrasive cloth is stuck 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 are for grinding profiles Grinding tools contoured accordingly. The glued on Abrasive cloth is sufficiently thin to fit the contours to be nestled. It has been shown that the Profile grinding Point supports of the abrasive on the abrasive profile can result in undesirable "Chatter marks" in the surface of the surface to be ground Workpiece occur. In addition, the point support under Local circumstances lead to such high pressure that occurring Frictional heat leads to "burning" of the abrasive. About that In addition, an intermediate sanding with abrasive cloth is not possible because the paint 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.It has already been proposed to overcome these disadvantages been, abrasive cloth through a foam strip too replace in the one to be brought into contact with the workpiece abrasive surface corresponding to granular abrasive material is involved. Such a foam strip as Abrasives can only be used for intermediate sanding deploy. This is what can be achieved for the sanded wood Grinding is not aggressive enough. Beyond that especially in the case of rotating grinding tools the core of the foam strip at speeds above 1200 rpm due to centrifugal forces and the abrasive thereby becoming unstable. Another major disadvantage is that workpiece to be ground the foam formed Abrasive rolls due to the abrasive pressure, causing on the abrasive surface the grain bond of the abrasive Material loosens 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 that corners of the workpiece into the soft elastic Pierce abrasives, causing pieces can be torn out. The insertion and removal of the Grinding tools therefore require a high level of technical effort on appropriate units and machines.
Nach der FR-A-2 622 136 ist es bekannt, die Arbeitsfläche eines rotierenden zylinderförmigen Schleifwerkzeugs mit aufgeklebtem Schaumstoff zu polstern und auf die Umfangsfläche des Polsters ein Schleifpapier zu kleben.According to FR-A-2 622 136 it is known to be the working surface of a rotating cylindrical grinding tool with glued on To pad and onto the peripheral surface of the Upholstery to stick a sandpaper.
Der Erfindung liegt die Aufgabe zugrunde, ein Schleifmittel für ein umlaufendes Maschinen-Schleifwerkzeug zu schaffen bei dem die vorbeschriebenen Nachteile nicht auftreten.The invention is based, an abrasive for a task revolving To create machine grinding tool where the Disadvantages described above do not occur.
Diese Aufgabe ist erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. This object is achieved by the features of claim 1 solved.
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.Abrasive cloths to be sanded relatively aggressively, taking on Because of the relining of the abrasive cloth with a elastic padding whose disadvantages do not occur. At the Grinding with the grinding tool according to the invention "Chatter marks" do not appear and the abrasive cannot either burn; because no frictional heat builds up because of the Grinding pressure is even. The grinding tool is suitable This is advantageous for grinding profiles, as a large abrasive pad on the workpiece is. Larger deviations in shape are advantageous and dimensional tolerances balanced.
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 one that is only suitable for intermediate sanding Foam tape with bound on one surface abrasive grains comprising abrasive grains, has such equipped grinding tool the advantage that the relative soft padding is protected under the abrasive cloth, so that pieces are not torn out. instability by centrifugal forces is due to the mechanical strength of the prevents the abrasive cloth covering the pad.
Für das Polster kann deshalb ein geeigneter Schaumstoff mit entsprechender Porigkeit und Elastizität gewählt werden.A suitable foam can therefore be used for the upholstery appropriate porosity and elasticity can be selected.
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 one Grinding wheel, can be in preparation for the grinding process his work surface with a foam pad be occupied. Then an abrasive cloth is placed over it placed the free surface of the foam pad covers.
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 in turn can be glued to the upholstery. In this way you can easily contoured Working surfaces of grinding tools for profile grinding equip.
Mit dem erfindungsgemäßen Schleifmittel kann relativ aggressiv geschliffen werden, wobei aufgrund der Unterfütterung des Schleifleinens mit einem elastischen Polster dessen Nachteile nicht auftreten. Beim Schleifen mit dem erfindungsgemäßen Schleifmittel treten "Rattermarken" nicht auf, und das Schleifmittel kann auch nicht brennen; denn es baut sich keine Reibungswärme auf, weil der Schleifandruck gleichmäßig ist. Das Schleifmittel 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 abrasive according to the invention can be relative be ground aggressively, due to the Lining the abrasive cloth with an elastic Upholstery whose disadvantages do not occur. When grinding with "chatter marks" occur in the abrasive according to the invention not on and the abrasive cannot burn; because no frictional heat builds up because of the Grinding pressure is even. The abrasive is suitable therefore advantageous for grinding profiles, since a large abrasive pad on the workpiece is. Larger deviations in shape are advantageous and dimensional tolerances balanced.
Gegenüber dem nur für den Lackzwischenschliff geeigneten, ein Schaumstoffband mit an einer Oberfläche eingebundenen abrasiven Körnern umfassenden Schleifmittel, hat ein derart ausgerüstetes Schleifmittel 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 one that is only suitable for intermediate sanding Foam tape with bound on one surface abrasive grains comprising abrasive grains, has such equipped abrasive the advantage that the relative soft padding is protected under the abrasive cloth, so that pieces are not torn out. instability by centrifugal forces is due to the mechanical strength of the prevents the abrasive cloth covering the pad.
Für das Polster kann deshalb ein geeigneter Schaumstoff mit entsprechender Porigkeit und Elastizität gewählt werden.A suitable foam can therefore be used for the upholstery appropriate porosity and elasticity can be selected.
Das Schleifleinen und das Polster liegen in Form von Streifen vor, die lediglich auf entsprechende Länge geschnitten werden.The abrasive cloth and the upholstery are in the form of strips before that just cut to the appropriate length become.
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 broader than the upholstery strip. This enables the longitudinal edges of the abrasive cloth strip over the longitudinal edges of the upholstery strip to pull and on the grinding tool, for example a rotating grinding wheel To fix glue. The cushion is therefore under the Abrasive cloth completely encapsulated and against mechanical Impacts protected.
Bei dem erfindungsgemäßen Schleifmittel, mit dem sich ein Schleifwerkzeug ausrüsten läßt, ist ein Streifenmittelbereich des Schleifleinen-Streifens mit einem Polster-Streifen beschichtet. 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.In the abrasive according to the invention, with which a Equipping the grinding tool is a central strip area of the abrasive cloth strip with a cushion strip coated. By appropriate prefabrication can a one-piece made of upholstery and abrasive cloth Abrasives are provided in strips or Band form is present. Can from the abrasive strip Cut sections of appropriate length with which equip the work surfaces of a grinding tool to let.
Damit die Ausrüstung auch von konturierten Arbeitsflächen problemlos möglich ist, weist wenigstens einer der Längsränder des Schneifmittelstreifens 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 easily possible, at least one of the Notches on the longitudinal edges of the abrasive strip. Preferably, both longitudinal edges of the Abrasive strip with corresponding notches provided that the abrasive strip is nestled in corresponding contours in the work surface of a Facilitate grinding tool. The notches are like this attached that they are at least partially in each protrude into the adjacent edge of the upholstery strip. The Pad strips on the underside of the loop it does not hinder those for nestling into the Contours of the work surface necessary deformations.
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 preferred as parallel to the respective longitudinal edge of the abrasive extending hole row, being in each hole a longitudinal edge incision is made.
Der Polster-Streifen kann an der Unterseite des Schleifleinen-Streifens mit entsprechenden Mitteln, beispielsweise Klebstoffen, befestigt werden.The pad strip can be on the underside of the abrasive cloth strip with 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.To the abrasive according to the invention on a grinding tool to be able to attach them to the work surface coming to the bottom of the abrasive cloth strip and the padding strip arranged on it Coating from activatable by preferably dissolving Glue on.
