Definitions
- the invention relates to an abrasive body, as well as a suitable for application to a machine grinding plate or grinding plate or to an actuatable abrasive holder with or without suction, suitable adapter according to the preamble of the main claim, the independent claims and claim 27, which can be used separately or in combination.
- Abrasive bodies in particular machine-adaptable abrasive bodies, are known in the most varied of embodiments with regard to structure and geometric shape.
- the sanding dust In order to achieve a perfect sanding result, the sanding dust must be continuously removed. If there is no such removal of the grinding dust or if such removal is insufficient, this leads to clogging of the grinding wheel, so that e.g. the individual abrasive grain can no longer take effect. The result of this is an unsatisfactory grinding result and a considerably shortened service life of the grinding wheel.
- the present invention is therefore based on the object of providing a grinding wheel and corresponding adaptation means for machines or manual tools, which effectively counteracts the described disadvantage of the prior art and thereby ensures continuous, regular and satisfactory removal of the grinding dust, both individually and can be used in combination.
- both the grinding wheel and the adapter used for some work-related fastenings now have a network of openings which are mutually, i.e. communicate with each other, as well as, for example, in connection with the suction device of the machine, so that both the suction air and the particle flow become effective and the dust can be removed.
- the perforation in one layer of the grinding wheel if the layer below or above it is gas and particle permeable. In the case of other grinding wheels, with a different layer structure, it may make sense not to let the perforation penetrate through one, but through several or all layers.
- the present invention is characterized in that, on the one hand, a machine-adaptable grinding wheel is formed by means of this grinding wheel, which consists of at least one layer containing the abrasive and which is applied directly or indirectly with the aid of an adapter
- the grinding plate or the grinding plate of the machine can be fastened to suit the work and in which means are provided which can cooperate with suction devices of the grinding plate or the grinding plate of the machine, the essence of the present invention being that at least the grinding body has a perforation which is approximately uniformly above the entire surface of the grinding body is distributed or at least partially arranged and at least penetrates the layer containing the abrasive, the spacing of the individual perforations forming the perforations from one another and from the suction devices of the grinding plate or the grinding plate being arranged in such a way that an almost jam-free transport of the Grinding dust is caused.
- the present invention provides an abrasive body which can be applied to a manually operated abrasive holder, which is also equipped with suction devices and is coupled to an external suction system.
- this abrasive is characterized in that it consists of at least one layer containing the abrasive and that can be directly or indirectly attached to an abrasive holder with the help of an adapter and in which means are also provided which can interact with suction devices of the abrasive holder.
- the essence of this grinding wheel is characterized in that at least the grinding wheel has a perforation which is approximately uniformly distributed over the entire surface of the grinding wheel or at least partially arranged and at least penetrates the layer containing the abrasive, the spacing of the individual perforations forming the perforations being arranged with respect to one another and with respect to the suction devices of the abrasive holder such that the grinding dust is transported almost without dust.
- the invention provides a grinding wheel which effects a satisfactory removal of the grinding dust without suction devices. It was recognized that the presence of the perforation removes the grinding dust from the grinding surface solely by the contact pressure and forces it into zones and layers behind the grinding plane. Clogging of the abrasive grains is almost avoided.
- the adapter also has a perforation which interacts with the perforation of the grinding wheel.
- a first particularly preferred embodiment of the present invention provides an abrasive body which consists of the layer containing the abrasive and / or the layer carrying or embedding the abrasive and / or the Velcro adaptation layer, which are penetrated together by the perforation.
- An auxiliary functional layer can be arranged between the layer containing the abrasive or its carrier or embedding layer and the Velcro adaptation layer.
- Such auxiliary function layers can be formed as elastic adaptation layers or compensation layers, for example made of foam.
- This Auxiliary function layers can also have a temperature blocking effect and be suitable for both wet and dry grinding. All the layers forming the grinding wheel are preferably penetrated by a common perforation.
- the auxiliary functional layer consists of a foam-like structure, it does not provide any perforation, but rather forms communication and transport channels through its foam-like structure, between the perforations in the adjacent layer and the suction devices of the grinding plate or the tools used.
- the perforation as well as the communication channels can flow through gas and particles.
- the shapes of the perforations forming the perforation can be circular, angular and oval. They can also be formed by slit-like openings which are aligned linearly or in an arc shape. This applies to both the perforation of the grinding wheel and the perforation of the adapter. Both the grinding wheel and the adapter can be disc-shaped, circular, angular, i.e. be rectangular or triangular or star-shaped.
- the abrasive backing consists of paper, fabric or a non-woven.
- the present invention also provides an adapter which is suitable for a machine or abrasive holder arrangement of a conventional as well as an abrasive body according to claims 1 and 26 and is characterized in that the adapter consists of a Velcro adaptation layer, a foam particle layer and a velor layer, whereby the one pointing to the grinding wheel Velcro adaptation layer is penetrated by the perforation.
- the perforation as such both in the grinding wheel and in the adapter, is to be arranged where the layer as such is impermeable to gas or particles.
- FIGS. 4 and 5 show a grinding plate 5, which is equipped with suction devices 7, here individual radially arranged bores. The removed grinding dust is conventionally fed to a collecting bag via these suction devices 7, the actual suction device being integrated on or in the grinding device.
- This representation is representative of a grinding plate or another abrasive holder 6 with or without suction devices.
- the abrasives for example circular grinding wheels
- the abrasives are also provided with openings which are to be applied in a congruent manner with the suction devices 7.
- the reason for this lies in the actual system.
- the sanding plate 5 has a Velcro adaptation surface 17. Above it is a pressure and impact-compensating softer layer 18. Both the latter layer and the perforation surface are firmly attached to a support plate 19, which has a connecting element 20 to the machine.
- the Velcro adaptation surface 17 as well as the soft layer 18 and the support plate 19 of the grinding plate are penetrated by the suction devices 7 in the form of openings or bores.
- a grinding wheel 1 according to FIGS. 1 to 3 and an adapter according to FIGS. 5 to 7 are now created.
- the general idea of the invention is expressed, for example, in FIGS. 1 to 3.
- the grinding body 1 is provided with a perforation 8, which is distributed over the entire surface, for example.
- the grinding wheel 1 can be formed from a wide variety of layers. This depends on the respective grinding process, quality of the ground layer and the material to be found. At least the layer 3 carrying the abrasive 2 is according to the invention penetrated by the perforations 9 forming the perforation 8.
- the abrasive body 1 according to the invention is formed from the layer 3 having the abrasive 2 and the layer 10 carrying the abrasive 2 or embedding the abrasive 2 and a Velcro adaptation layer 11, all of which are penetrated by the perforation 8.
- this can also be an auxiliary functional layer 12 arranged between the layer 3 containing the abrasive 2 or its carrier or embedding layer 10 and the Velcro adaptation layer 11, which can be present, for example, as a foam body for the purpose of elastic adaptation and compensation, but also as a temperature barrier layer.
- This can also be produced for wet or dry grinding designs.
- all the layers forming the grinding body 1 can be penetrated by a common perforation or only individual layers can be penetrated by this.
- auxiliary function layer 12 has no perforation 8, but communication channels 13 between the perforations 9 of the perforation 8 and the through their own foam-like structure Suction devices 7 of the grinding plate 5 forms. It goes without saying that both the perforation 8 and the communication channels 13 can flow through both gas and particles. The same also applies to the construction of the adapter according to FIGS. 6 to 7.
- the adapter 4 also provides the perforation 8 here, which, if the adapter 4 consists of a Velcro adaptation layer 14, only penetrates through it when a foam particle layer 15 is also shown, as shown here a subsequent velor layer 16, which can itself be flowed through.
- FIG. 8 shows a perforation 8 which is formed from circular openings.
- FIG. 9 shows star-shaped openings 9 and FIG. 10 polygonal openings 9. These openings can be symmetrical like the square, rectangular or triangular openings according to FIGS. 11 to 13 or also of asymmetrical shape.
- FIG. 14 shows oval openings 9. The choice of the geometric shape is determined by the respective application. Thus, slot-like openings 9 in a linear (FIG. 15) or arc-shaped alignment (FIG. 16) are also possible.
- the essence of the invention is determined, inter alia, by the perforations in the grinding wheel and in the adapter or their layer structure. It was thus recognized that both the grinding wheel and the adapter can be used separately or in combination with one another.
- the adapter according to the invention can even be used with conventional Abrasive bodies having perforations can be used in the sense of the inventive concept.

Abstract
Description
Die Erfindung betrifft einen Schleifkörper, sowie einen zum arbeitsgerechten Aufbringen auf einen Maschinenschleifteller oder Schleifplatte bzw. auf einen betätigbaren Schleifmittelhalter mit oder ohne Absaugung, geeigneten Adapter nach dem Oberbegriff des Hauptanspruchs der Nebenansprüche und des Anspruchs 27, die getrennt oder in Kombination verwendbar sind.The invention relates to an abrasive body, as well as a suitable for application to a machine grinding plate or grinding plate or to an actuatable abrasive holder with or without suction, suitable adapter according to the preamble of the main claim, the independent claims and claim 27, which can be used separately or in combination.
Schleifkörper, insbesondere maschinenadaptierbare Schleifköper, sind in den vielfältigsten Ausführungsformen, hinsichtlich Aufbau und geometrischer Form bekannt.Abrasive bodies, in particular machine-adaptable abrasive bodies, are known in the most varied of embodiments with regard to structure and geometric shape.
Um ein einwandfreies Schleifergebnis zu erzielen, bedarf es des kontinuierlichen Abtransports des Schleifstaubes. Ist ein solcher Abtransport des Schleifstaubes nicht vorhanden oder wird ein solcher Abtransport nur unzureichend vorgenommen, führt dies zum Zusetzen der Schleifscheibe, so daß z.B. das einzelne Schleifkorn nicht mehr wirksam werden kann. Die Folge hieraus ist ein nicht zufriedenstellendes Schleifergebnis und eine beträchtlich verkürzte Standzeit des Schleifkörpers.In order to achieve a perfect sanding result, the sanding dust must be continuously removed. If there is no such removal of the grinding dust or if such removal is insufficient, this leads to clogging of the grinding wheel, so that e.g. the individual abrasive grain can no longer take effect. The result of this is an unsatisfactory grinding result and a considerably shortened service life of the grinding wheel.
Die Konsequenz hieraus war beispielsweise die Anordnung von Absaugeinrichtungen im Schleifteller oder der Schleifplatte der Maschine, wobei der Schleifkörper mit Mitteln versehen wurde, so daß die Absaugung theoretisch dadurch erfüllt werden sollte, in dem sich im Schleifkörper befindliche Lochungen mit den Absaugkanälen des Schleiftellers oder der Platte überragten. Diese Maßnahmen gelten auch für manuell nutzbare Schleifmittelhalter, die mit Absaugeinrichtungen versehen sein können.The consequence of this was, for example, the arrangement of suction devices in the grinding plate or the grinding plate of the machine, the grinding element being provided with means so that the suction should theoretically be achieved by perforations in the grinding element with the suction channels of the grinding plate or plate towered. These measures also apply to manually usable abrasive holders that can be equipped with suction devices.
Nun ist es aber, um eine grundlegende Funktion sicherzustellen, erforderlich, daß der Anwender den Schleifkörper mit seinen Durchbrechungen deckungsgleich zu den Ansaugkanälen des Schleiftellers bzw. der Schleifplatte oder den weiteren Werkzeughilfsmittel aufbringt, worauf aber erfahrungsgemäß bei den meisten Anwendern nicht geachtet wird. Noch schwieriger erweist sich die Erfüllung dieser Voraussetzung, wenn zwischen Schleifkörper und Schleifteller bzw. Schleifplatte oder Schleifklotz oder ähnlichem ein Adapterteil zuzuordnen ist. In der Praxis ist jedoch auch bei vorschriftsmäßiger Übereinanderanordnung der adaptierten Teile kein zufriedenstellender Abtransport des Schleifstaubes zu erwarten. Der Schleifstaub wird nämlich nicht dort aufgesaugt oder abtransportiert, wo er entsteht, sondern dort wo er durch die Rotation oder Oszillationsbewegung des Schleifkörpers unter die Ansauglochungen transportiert wird.
Zwischenzeitlich wird der Schleifstaub sowohl auf dem Werkstück verrieben als auch in die Schleiffläche gepreßt, wo er zum Zusetzen der Schleifmittel führt. Dies führt letztendlich zu einem qualitativ nicht zufriedenstellenden Schleifergebnis.Now, in order to ensure a basic function, it is necessary that the user applies the grinding body with its openings congruent to the suction channels of the grinding plate or the grinding plate or the other tool aids, but experience has shown that most users do not pay attention to this. This proves to be even more difficult if an adapter part is to be assigned between the grinding body and the grinding plate or grinding plate or grinding block or the like. In practice, however, a satisfactory removal of the grinding dust is not to be expected even when the adapted parts are arranged one above the other in accordance with the regulations. The grinding dust is not sucked up or removed where it is created, but where it is transported under the suction holes by the rotation or oscillation of the grinding wheel.
In the meantime, the grinding dust is both ground on the workpiece and pressed into the grinding surface, where it leads to clogging of the abrasives. This ultimately leads to an unsatisfactory grinding result.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen Schleifkörper sowie entsprechende Adaptionsmittel für Maschinen oder manuelle Werkzeuge zu schaffen, der dem geschilderten Nachteil des Standes der Technik wirkungsvoll entgegentritt und dabei einen kontinuierlichen, regelmäßigen und zufriedenstellenden Abtransport des Schleifstaubes sicherstellt, welche sowohl einzeln als auch im Kombination miteinander verwendbar sind.The present invention is therefore based on the object of providing a grinding wheel and corresponding adaptation means for machines or manual tools, which effectively counteracts the described disadvantage of the prior art and thereby ensures continuous, regular and satisfactory removal of the grinding dust, both individually and can be used in combination.
Dies wird erfindungsgemäß durch einen Schleifkörper nach dem Kennzeichen des vorgeschlagenen Hauptanspruches bzw. der Nebenansprüche sowie durch einen Adapter nach dem Kennzeichen des vorgeschlagenen Anspruchs 27 gelöst.According to the invention, this is solved by a grinding wheel according to the characterizing part of the proposed main claim or the secondary claims and by an adapter according to the characterizing part of the proposed claim 27.
Besonders bevorzugte Weiterbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Particularly preferred developments of the invention are characterized in the subclaims.
Erfindungsgemäß weist nun sowohl der Schleifkörper als auch der für manche arbeitsgerechte Befestigungen verwendete Adapter ein Netz von Durchbrechungen auf, die sowohl untereinander, d.h. miteinander kommunizieren, als auch beispielsweise mit der Absaugeinrichtung der Maschine in Verbindung stehen, so daß sowohl die Absaugluft als auch der Partikelstrom wirksam wird und der Staub abgefördert werden kann.According to the invention, both the grinding wheel and the adapter used for some work-related fastenings now have a network of openings which are mutually, i.e. communicate with each other, as well as, for example, in connection with the suction device of the machine, so that both the suction air and the particle flow become effective and the dust can be removed.
Je nach dem,wie der Aufbau des Schleifkörpers gewählt ist, ist es ausreichend,die Perforation in einer Schicht des Schleifkörpers anzuordnen, wenn die darunter oder darüberliegende Schicht gas- und partikeldurchlässig ist. Bei wiederum anderen Schleifkörpern, mit anders geartetem Schichtaufbau kann es sinnvoll sein, die Perforation nicht durch eine,sondern durch mehrere oder alle Schichten, durchdringen zu lassen.Depending on how the structure of the grinding wheel is chosen, it is sufficient to arrange the perforation in one layer of the grinding wheel if the layer below or above it is gas and particle permeable. In the case of other grinding wheels, with a different layer structure, it may make sense not to let the perforation penetrate through one, but through several or all layers.
Gleiches gilt für den Aufbau des Adapters.The same applies to the construction of the adapter.
Daher zeichnet sich die vorliegende Erfindung dadurch aus, daß mittels dieser einerseits ein maschinenadaptierbarer Schleifkörper gebildet ist, der mindestens aus einer das Schleifmittel aufweisenden Schicht besteht und der direkt oder mit Hilfe eines Adapters indirekt auf den Schleifteller oder die Schleifplatte der Maschine arbeitsgerecht befestigbar ist und bei denen Mittel vorgesehen sind, die mit Absaugeinrichtungen des Schleiftellers oder der Schleifplatte der Maschine zusammenwirken können, wobei das Wesen der vorliegenden Erfindung darin liegt, daß mindestens der Schleifkörper eine Perforation aufweist, die annähernd gleichmäßig über die gesamte Fläche des Schleifkörpers verteilt oder zumindest partiell angeordnet ist und zumindest die das Schleifmittel aufweisende Schicht durchdringt, wobei der Abstand der einzelnen, die Perforation bildenden Durchbrechungen zueinander und gegenüber den Absaugeinrichtungen des Schleiftellers oder der Schleifplatte so angeordnet sind, daß ein nahezu stauloser Transport des Schleifstaubes bewirkt ist.Therefore, the present invention is characterized in that, on the one hand, a machine-adaptable grinding wheel is formed by means of this grinding wheel, which consists of at least one layer containing the abrasive and which is applied directly or indirectly with the aid of an adapter The grinding plate or the grinding plate of the machine can be fastened to suit the work and in which means are provided which can cooperate with suction devices of the grinding plate or the grinding plate of the machine, the essence of the present invention being that at least the grinding body has a perforation which is approximately uniformly above the entire surface of the grinding body is distributed or at least partially arranged and at least penetrates the layer containing the abrasive, the spacing of the individual perforations forming the perforations from one another and from the suction devices of the grinding plate or the grinding plate being arranged in such a way that an almost jam-free transport of the Grinding dust is caused.
Andererseits wird durch die vorliegende Erfindung ein Schleifkörper bereitgestellt, der auf einem manuell betätigbaren Schleifmittelhalter aufbringbar ist, welcher ebenfalls mit Absaugeinrichtungen bestückt ist und an eine externe Absauganlage gekoppelt wird.On the other hand, the present invention provides an abrasive body which can be applied to a manually operated abrasive holder, which is also equipped with suction devices and is coupled to an external suction system.
Erfindungsgemäß zeichnet dieser Schleifkörper dadurch aus, daß er mindestens aus einer das Schleifmittel aufweisenden Schicht besteht und der direkt oder mit Hilfe eines Adapters indirekt auf einen Schleifmittelhalter arbeitsgerecht befestigbar ist und bei dem ferner Mittel vorgesehen sind, die mit Absaugeinrichtungen des Schleifmittelhalters zusammenwirken können. Das Wesen dieses Schleifkörpers ist dadurch gekennzeichnet, daß mindestens der Schleifkörper eine Perforation aufweist, die annähernd gleichmäßig über die gesamte Fläche des Schleifkörpers verteilt oder zumindest partiell angeordnet ist und zumindest die das Schleifmittel aufweisende Schicht durchdringt, wobei der Abstand der einzelnen, die Perforation bildenden Durchbrechungen zueinander und gegenüber den Absaugeinrichtungen des Schleifmittelhalters so angeordnet sind, daß ein nahezu staubloser Transport des Schleifstaubes bewirkt ist.According to the invention, this abrasive is characterized in that it consists of at least one layer containing the abrasive and that can be directly or indirectly attached to an abrasive holder with the help of an adapter and in which means are also provided which can interact with suction devices of the abrasive holder. The essence of this grinding wheel is characterized in that at least the grinding wheel has a perforation which is approximately uniformly distributed over the entire surface of the grinding wheel or at least partially arranged and at least penetrates the layer containing the abrasive, the spacing of the individual perforations forming the perforations being arranged with respect to one another and with respect to the suction devices of the abrasive holder such that the grinding dust is transported almost without dust.
Ferner wird durch die Erfindung ein Schleifkörper geschaffen, der ohne Absaugeinrichtungen einen zufriedenstellenden Abtransport des Schleifstaubes bewirkt. Es wurd erkannt, daß durch das Vorhandensein der Perforation der Schleifstaub alleine durch den Anpreßdruck von der Schleiffläche entfernt und in Zonen und Schichten hinter der Schleifebene gedrängt wird. Somit ist ein Zusetzen der Schleifkörner nahezu vermieden.Furthermore, the invention provides a grinding wheel which effects a satisfactory removal of the grinding dust without suction devices. It was recognized that the presence of the perforation removes the grinding dust from the grinding surface solely by the contact pressure and forces it into zones and layers behind the grinding plane. Clogging of the abrasive grains is almost avoided.
Bei einer besonders bevorzugten Ausführungsform ist vorgesehen, daß auch der Adapter eine mit der Perforation des Schleifkörpers zusammenwirkende Perforation aufweist.In a particularly preferred embodiment it is provided that the adapter also has a perforation which interacts with the perforation of the grinding wheel.
Eine erste besonders bevorzugte Ausführungsvorm der vorliegenden Erfindung sieht einen Schleifkörper vor, der aus der das Schleifmittel aufweisenden Schicht und/oder der das Schleifmittel tragenden oder das Schleifmittel einbettenden Schicht und/oder der Klettadaptionsschicht besteht, die gemeinsam von der Perforation durchdrungen sind.
Zwischen der das Schleifmittel aufweisenden Schicht oder deren Träger oder Einbettungsschicht und der Klettadaptionsschicht kann eine Hilfsfunktionsschicht angeordnet sein. Solche Hilfsfunktionsschichten können als elastische Anpassungsschichten oder Ausgleichsschichten, beispielsweise aus Schaumstoff gebildet sein. Diese Hilfsfunktionsschichten können aber auch eine Temperatursperrwirkung besitzen und sowohl für den Naßals auch für den Trockenschliff geeignet sein. Bevorzugterweise sind alle den Schleifkörper bildenden Schichten von einer gemeinsamen Perforierung durchsetzt. Jedoch insbesondere,wenn die Hilfsfunktionschicht aus einem schaumartigen Aufbau besteht, sieht diese keine Perforation vor, sondern bildet selbst durch ihren schaumartigen Aufbau Kommuniktions- und Transportkanäle, zwischen den Durchbrechungen der Perforation der benachbarten Schicht und den Absaugeinrichtungen des Schleiftellers oder der verwendeten Werkzeuge. Die Perforation als auch die Kommunikationskanäle sind dabei gas- und partikeldurchströmbar.A first particularly preferred embodiment of the present invention provides an abrasive body which consists of the layer containing the abrasive and / or the layer carrying or embedding the abrasive and / or the Velcro adaptation layer, which are penetrated together by the perforation.
An auxiliary functional layer can be arranged between the layer containing the abrasive or its carrier or embedding layer and the Velcro adaptation layer. Such auxiliary function layers can be formed as elastic adaptation layers or compensation layers, for example made of foam. This Auxiliary function layers can also have a temperature blocking effect and be suitable for both wet and dry grinding. All the layers forming the grinding wheel are preferably penetrated by a common perforation. However, in particular if the auxiliary functional layer consists of a foam-like structure, it does not provide any perforation, but rather forms communication and transport channels through its foam-like structure, between the perforations in the adjacent layer and the suction devices of the grinding plate or the tools used. The perforation as well as the communication channels can flow through gas and particles.
Die Formen der die Perforation bildenden Durchbrechungen können sowohl kreisförmig, eckig und oval sein. Sie können auch durch schlitzartige Durchbrechungen, welche linear oder bogenförmig ausgerichtet sind, gebildet werden. Dies gilt sowohl für die Perforation des Schleifkörpers,als auch für die Perforation des Adapters. Sowohl der Schleifkörper als auch der Adapter kann scheibenförmig, kreisrund, eckig, d.h. rechteckig oder dreieckig oder auch sternförmig ausgebildet sein. Der Schleifmittelträger besteht aus Papier, Gewebe oder einem Vlies.The shapes of the perforations forming the perforation can be circular, angular and oval. They can also be formed by slit-like openings which are aligned linearly or in an arc shape. This applies to both the perforation of the grinding wheel and the perforation of the adapter. Both the grinding wheel and the adapter can be disc-shaped, circular, angular, i.e. be rectangular or triangular or star-shaped. The abrasive backing consists of paper, fabric or a non-woven.
Die vorliegende Erfindung stellt auch einen Adapter bereit, der zu arbeitsgerechten Maschinen- oder Schleifmittelhalteranordnung eines konventionellen als auch eines Schleifkörpers nach den Ansprüchen 1 bis 26 geeignet ist und kennzeichnet sich dadurch, daß der Adapter aus einer Klettadaptionsschicht, einer Schaumpartikelschicht und einer Veloursschicht besteht, wobei die zum Schleifkörper hinweisende Klettadaptionsschicht mit von der Perforation durchdrungen ist. Die Perforation als solche, sowohl im Schleifkörper als auch im Adapter ist erfindungsgemäß dort anzuordnen, wo die Schicht als solche gas- oder partikelstromundurchlässig ist. Die Eigenschaft des Schleifkörpers hinsichtlich Aufbau und Schichten, mit Ausnahme der Schleifschicht, gelten auch für die des Adapters.The present invention also provides an adapter which is suitable for a machine or abrasive holder arrangement of a conventional as well as an abrasive body according to
Anhand den beigefügten Zeichnungen, die besonders bevorzugte Ausführungsbeispiele der Erfindung zeigen, wird diese nun näher beschrieben.

Zunächst wird auf die Figuren 4 und 5 Bezug genommen. Die Figuren 4 und 5 zeigen einen Schleifteller 5, der mit Absaugeinrichtungen 7, hier einzelne radial angeordnete Bohrungen, ausgestattet ist. Über diese Absaugeinrichtungen 7 wird herkömmlicherweise der abgetragene Schleifstaub einem Auffangbeutel zugeführt, wobei die eigentliche Saugeinrichtung am oder im Schleifgerät integriert ist. Diese Darstellung ist stellvertretend für eine Schleifplatte oder einen sonstigen Schleifmittelhalter 6 mit oder ohne Absaugeinrichtungen.First, reference is made to FIGS. 4 and 5. Figures 4 and 5 show a grinding plate 5, which is equipped with
Es gilt nun erfindungsgemäß die funktionsgerechte Zuführung des Schleifstaubes zu diesen Absaugeinrichtungen 7 oder den gleichwertigen Abtransport sicherzustellen. Herkömmlicherweise sind hierzu die Schleifmittel, beispielsweise kreisrunde Schleifscheiben, ebenfalls mit Durchbrechungen versehen, die deckungsgleich zu den Absaugeinrichtungen 7 aufzubringen sind. Wie eingangs bereits erwähnt, kann dieser Stand der Technik nicht sicherstellen, daß das Schleifergebnis zufriedenstellend ausfällt. Der Grund hierfür liegt im eigentlichen System. Der Schleifteller 5 besitzt eine Klettadaptionsfläche 17. Darüber befindet sich eine druck- und stoßausgleichende weichere Schicht 18. Sowohl letztere Schicht als auch die Perforationsfläche sind fest auf einem Tragteller 19 aufgebracht, welcher ein Verbindungselement 20 zur Maschine besitzt. Sowohl die Klettadaptionsfläche 17 als auch die weiche Schicht 18 und der Tragteller 19 des Schleiftellers sind von den Absaugeinrichtungen 7 in Form von Durchbrechungen oder Bohrungen durchsetzt.According to the invention, it is now a matter of ensuring the functionally appropriate feeding of the grinding dust to these
Wird nun der Schleifkörper 1 unsachgemäß auf den Schleifteller 5 aufgebracht, d.h. wenn die herkömmlichen mit den Absaugeinrichtungen 7 deckungsgleichen Bohrungen der Schleifscheibe nicht exakt über die Absaugeinrichtung 7 positioniert werden, ist die Absaugung des Schleifstaubes zunichte gemacht.
Aber auch dann, wenn die Schleifscheibe ordnungsgemäß positioniert wird, ist eine kontinuierliche Absaugung aus den bereits genannten Gründen nicht gewährleistet.If the grinding
But even if the grinding wheel is properly positioned, continuous extraction is not guaranteed for the reasons already mentioned.
Erfindungsgemäß wird nun ein Schleifkörper 1 gemäß Figur 1 bis 3 sowie ein Adapter gemäß den Figuren 5 bis 7 geschaffen. Der allgemeine Erfindungsgedanke drückt sich beispielsweise in den Figuren 1 bis 3 aus. Erfindungsgemäß ist der Schleifkörper 1 mit einer Perforation 8 versehen, die sich beispielsweise über die gesamte Fläche verteilt. Der Schleifkörper 1 kann dabei aus verschiedensten Schichten gebildet werden. Dies ist abhängig vom jeweiligen Schleifverfahren, Güte der beschliffenen Schicht und dem anzutreffenden Material. Zumindest ist erfindungsgemäß die das Schleifmittel 2 tragende Schicht 3 von den die Perforation 8 bildenden Durchbrechungen 9 durchsetzt. Durch diese erfindungsgemäße Anordnung der Durchbrechungen 9 der Perforation 8 zueinander sowie gegenüber den Absaugeinrichtungen 7 des Schleiftellers 5 ist ein nahezu stauloser Transport des Schleifstaubes zu den Absaugeinrichtungen 7 bewirkt. Beispielsweise ist der erfindungsgemäße Schleifkörper 1, aus der das Schleifmittel 2 aufweisenden Schicht 3 und der das Schleifmittel 2 tragenden oder das Schleifmittel 2 einbettenden Schicht 10 und einer Klettadaptionsschicht 11 gebildet, die alle durch die Perforation 8 durchdrungen sind.According to the invention, a
Es kommen also Schleifkörper für diese Erfindung in Frage, bei denen der unterschiedlichste Schichtaufbau möglich ist. Beispielsweise kann dies auch gemäß Figur 3a eine zwischen der das Schleifmittel 2 aufweisenden Schicht 3 oder deren Träger oder Einbettungsschicht 10 und der Klettadaptionsschicht 11 angeordnete Hilfsfunktionsschicht 12 sein, die beispielsweise als Schaumkörper zum Zwecke der elastischen Anpassung und des Ausgleiches aber auch als Temperatursperrschicht vorliegen kann. Diese ist ebenfalls für Naß- oder Trockenschliffausführungen herstellbar.
Wie zuvor dargelegt, können alle den Schleifkörper 1 bildenden Schichten von einer gemeinsamen Perforation durchsetzt sein oder auch nur einzelne Schichten von dieser durchsetzt werden.
Eine Ausführungsform der vorliegenden Erfindung besteht darin, daß die Hilfsfunktionsschicht 12 keine Perforation 8 aufweist, sondern durch ihren eigenen schaumartigen Aufbau Kommunikationskanäle 13 zwischen den Durchbrechungen 9 der Perforation 8 und den Absaugeinrichtungen 7 des Schleiftellers 5 bildet. Es versteht sich hierbei, daß sowohl die Perforation 8 als auch die Kommunikationskanäle 13 sowohl gas- als auch partikeldurchströmbar sind. Gleiches gilt auch für den Aufbau des Adapters gemäß den Figuren 6 bis 7. Der Adapter 4 sieht auch hier die Perforation 8 vor, die, falls der Adapter 4 aus einer Klettadaptionsschicht 14 besteht, lediglich diese durchsetzt, wenn wie hier gezeigt eine Schaumpartikelschicht 15 mit einer darauf folgenden Veloursschicht 16, welche selbst durchströmbar sind, besteht.So there are grinding wheels for this invention in which the most varied layer structure is possible. For example, according to FIG. 3a, this can also be an auxiliary
As explained above, all the layers forming the grinding
An embodiment of the present invention is that the
Figur 8 zeigt eine Perforation 8 die aus kreisrunden Durchbrechungen gebildet ist. Figur 9 zeigt sternförmige durchbrechungen 9 und Figur 10 vieleckige Durchbrechungen 9. Diese Durchbrechungen können symmetrisch wie die quadratischen, rechteckigen oder dreieckigen Durchbrechungen gemäß den Figuren 11 bis 13 oder auch von assymetrischer Formgebung sein. Die Figur 14 zeigt ovale Durchbrechungen 9. Die Wahl der geometrischen Form wird durch den jeweiligen Anwendungsfall bestimmt. So kommen auch schlitzartige Durchbrechungen 9 in lineare (Figur 15) oder bogenförmige Ausrichtung (Figur 16) in Betracht. Das Wesen der Erfindung wird u.a. durch die Perforationen im Schleifkörper und im Adapter bzw. deren Schichtaufbau bestimmt. So wurde erkannt, daß sowohl der Schleifkörper als auch der Adapter separat oder auch in Kombination miteinander genutzt werden können. Der erfindungsgmäße Adapter kann sogar mit herkömmlichen,
Lochungen aufweisenden Schleifkörpern im Sinne des Erfindungsgedankens genutzt werden.FIG. 8 shows a
