Description

Die Erfindung betrifft eine Schleifbürste gemäß dem Oberbegriff des Anspruchs 1. Aus der US 2 443 413 ist eine solche Schleifbürste bekannt.The invention relates to an abrasive brush according to the preamble of claim 1. From the Such a grinding brush is known from US 2,443,413.

Die in Frage kommende Schleifbürste kann auch als Rotorbürste bezeichnet werden und wird in Schleifmaschinen eingesetzt. Dazu ist der Grundkörper mit einer Bohrung zum Aufstecken auf die Schleifwelle versehen. Aus den Streifenbürsten wird der sogenannten Bürstenbesatz gebildet. Dieser kann aus unterschiedlichen Materialien, wie zum Beispiel Rosshaar, Draht, Schleifkomborsten, Fiber und aus einem ähnlichen Material bestehen.The grinding brush in question can also be referred to as a rotor brush and is used in grinding machines. For this, the basic body with a Provide a hole for plugging onto the grinding shaft. From the strip brushes the so-called brush trim is formed. This can come from different Materials such as horsehair, wire, abrasive combs, fiber and from a similar material.

Die Schleifbürsten werden zum Schleifen, Entstauben und Reinigen, Glätten und Strukturieren von Holz, Metall, Kunststoffen und dergleichen verwendet. Als Schleifmittel dienen die Schleifgewebeabschnitte, die sich dann an die in Drehrichtung dahinter liegenden Streifenbürsten abstützen. Dadurch ist es möglich, dass auch unebene oder profilierte Werkstücke geschliffen werden können. Bei den Schleifbürsten sind die Schleifgewebeabschnitte Verschleißteile, so dass nach einer gewissen Schleifzeit die Wirkung nicht mehr erzielt wird.The sanding brushes are used for sanding, dusting and cleaning, smoothing and Structuring wood, metal, plastics and the like used. As Abrasives serve the abrasive cloth sections, which are then aligned in the direction of rotation Support strip brushes behind. This makes it possible for uneven or profiled workpieces can also be ground. Both Abrasive brushes are the abrasive cloth sections wearing parts, so after one certain grinding time the effect is no longer achieved.

Aus der US 2 443 413 ist eine Schleifbürste bekannt, bei der die Schleifgewebeabschnitte bis in das Innere des Grundkörpers geführt sind, so dass der darin eingebrachte Teil als Vorrat angesehen werden kann, der bei Abnutzung der Schleifgewebeabschnitte eine Nachstellung ermöglicht. Dazu ist es jedoch notwendig, dass beispielsweise Schrauben gelöst werden, um die Schleifgewebelagen um eine bestimmte Länge aus dem Grundkörper herauszuziehen. Das Nachstellen der Schleifgewebeabschnitte ist demzufolge sehr umständlich. Ferner ist es besonders nachteilig, dass eine verhältnismäßig große Länge der Schleifgewebeabschnitte als Rest zurückbleibt, wenn eine Nachstellung nicht mehr möglich ist. Diese Länge ergibt sich aus dem Abstand der äußeren Kanten der Streifenbürste zur Außenfläche oder Stirnfläche des Grundkörpers.From US 2,443,413 a sanding brush is known in which the sanding fabric sections are led into the interior of the base body, so that the introduced into it Part can be viewed as a stock, the wear of the abrasive cloth sections enables adjustment. However, this requires that For example, screws are loosened around the abrasive cloth layers by a certain amount Pull the length out of the body. The adjustment of the abrasive cloth sections is therefore very cumbersome. Furthermore, it is particularly disadvantageous that a relatively large length of the abrasive cloth sections as the rest remains when an adjustment is no longer possible. This length results from the distance of the outer edges of the strip brush to the outer surface or End face of the base body.

In der WO97/35688 wird ein Verfahren zum Herstellen von Streifenbürsten mit angrenzenden Schleifgewebeabschnitten beschrieben. Danach werden in zunächst U-förmige Klemmprofile um Kerne geschlagene Borsten eingebracht. Gleichzeitig werden auch die Schleifgewebeabschnitte zugeführt. Anschließend werden die parallelen Schenkel der Klemmprofile gebogen, so dass die eingebrachten Endbereiche festgeklemmt werden. Bei dieser Ausführung ragen die Schleifgewebeabschnitte bis in die Klemmprofile hinein. Eine Nachstellung ist bei dieser Ausführung nicht vorgesehen, so dass auch ein relativ großer Restanteil nach Abnutzung der Arbeitsflächen der Schleifgewebeabschnitte zurückbleibt.WO97 / 35688 describes a method for producing strip brushes adjacent abrasive cloth sections described. After that, in first U-shaped clamping profiles are inserted around the bristles. simultaneously the abrasive cloth sections are also fed. Then the parallel Leg of the clamping profiles bent so that the introduced end areas be clamped. In this version, the abrasive cloth sections protrude right into the clamping profiles. This version is an adjustment not provided, so that a relatively large residual proportion after wear of the working surfaces of the abrasive cloth sections remains.

Ausgehend von einer durch die US 2 443 413 vorbekannten Schleifbürste liegt der Erfindung die Aufgabe zugrunde, eine solche Schleifbürste der eingangs näher beschriebenen Art so auszubilden, dass die nicht mehr verwertbaren Reste der Schleifgewebeabschnitte wesentlich reduziert werden, so dass die Wirtschaftlichkeit erhöht wird. Ferner soll die Anzahl der auf dem Umfang oder auf der Stimfläche der Schleifbürste angeordneten Schleifgewebeabschnitte erhöht werden. Starting from a grinding brush previously known from US 2,443,413, the Invention based on the object, such a grinding brush described in more detail above Kind in such a way that the residues of the Abrasive cloth sections can be significantly reduced, making the economy is increased. Furthermore, the number of on the circumference or on the end face of the abrasive brush arranged abrasive cloth sections can be increased.

Die gestellte Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst .The object is achieved by the features of claim 1 ,

Bei der erfindungsgemäßen Schleifbürste ist der Grundkörper frei von dem Schleifgewebe. Der flexible Fuß kann so gestaltet sein, dass die Größe des daran befestigten Schleifgewebeabschnittes wesentlich kleiner ist als der nicht mehr zu verwertende Rest bei den bisher bekannten Schleifbürsten.In the abrasive brush according to the invention, the base body is free of that Shabu. The flexible foot can be designed so that the size of it attached abrasive cloth section is much smaller than that no longer utilizing rest in the previously known grinding brushes.

Da der flexible Fuß zusammen mit den Streifenbürsten in der Nut festgelegt wird, entfallen zusätzliche Mittel, um den Schleifgewebeabschnitt festzulegen. Das Wechseln der Schleifgewebeabschnitte ist demzufolge in äußerst kurzer Zeit durchzuführen, da die Nuten und das Klemmprofil der Streifenbürsten so gestaltet sind, dass ein Formschluss erzielt wird. Dies ist beispielsweise durch Nuten möglich, die im Querschnitt schwalbenschwanzförmig gestaltet sind.Since the flexible base is fixed in the groove together with the strip brushes, there is no additional means to fix the abrasive cloth section. The Changing the abrasive cloth sections is therefore extremely short because the grooves and the clamping profile of the strip brushes are designed in this way are that a positive fit is achieved. This is possible, for example, through grooves, which are dovetail-shaped in cross-section.

Die Schleifbürsten werden mit einer relativ großen Drehzahl angetrieben. Damit die Schleifgewebeabschnitte durch die Fliehkraft nicht aus den Nuten herausgezogen werden, ist zur Erhöhung der Sicherheit vorgesehen, daß vorzugsweise, zumindest der eingespannte Bereich des flexiblen Fußes winke!- oder U-förmig ausgebildet ist und das Klemmprofil entsprechend umgreift.The grinding brushes are driven at a relatively high speed. In order to the sections of abrasive cloth are not pulled out of the grooves by centrifugal force is to increase the security provided that preferably, at least the clamped area of the flexible foot wave! - or U-shaped and the clamping profile accordingly embraces.

In weiterer Ausgestaltung ist vorgesehen, daß der Grund der Nuten auf wenigstens zwei unterschiedlichen Kreisen oder Ebenen verläuft.In a further embodiment it is provided that the bottom of the grooves on at least two different circles or levels.

Der Grund der Nuten verläuft auf unterschiedlichen Kreisen, wenn die Umfangsfläche des Grundkörpers mit den Streifenbürsten bestückt ist. Der Grund der Nuten steht dann in einem wechselnden Abstand zur Drehachse der Schleifscheibe. Sofern die Stirnfläche des Grundkörpers damit bestückt ist, steht der Grund der Nuten in wechselnden Abständen zur Stirnfläche. Dadurch können die Schleifgewebeabschnitte noch besser ausgenutzt werden, da es möglich ist, daß sie zuerst in die Nuten eingesetzt werden, deren Grund die größten Abstände zur Umfangsfläche bzw. zur Stirnfläche des Grundkörpers haben. Wenn die Schleifgewebeabschnitte um ein bestimmtes Maß abgenutzt sind, können sie dann in die Nuten eingesetzt werden, deren Grund im geringeren Abstand zur Umfangsfläche bzw. zur Stirnfläche liegt. Auf diese Weise lassen sich die Schleifgewebeabschnitte nahezu restlos aufbrauchen.The bottom of the grooves runs on different circles when the peripheral surface of the base body is equipped with the strip brushes. The bottom of the grooves is there then at an alternating distance from the axis of rotation of the grinding wheel. If the End face of the base body is equipped with it, the bottom of the grooves is in alternating Distances to the face. This allows the abrasive cloth sections be exploited even better, since it is possible that they are inserted into the grooves first are, the reason the greatest distances from the circumferential surface or the end face of the main body. If the abrasive cloth sections by a certain Dimension are worn out, they can then be inserted into the grooves, the reason for which is the smaller distance from the peripheral surface or from the end surface. On in this way, the abrasive cloth sections can be used up almost completely.

Zweckmäßigerweise sind die Nuten nach einem Schema im Grundkörper angeordnet. So ist es vorteilhaft, wenn die Nuten mit den unterschiedlichen Tiefen wechselweise angeordnet sind, da dann die Möglichkeit besteht, daß die Winkelabstände zwischen den Nuten gegenüber den bekannten Ausführungen verkleinert werden, so daß auf dem Umfang bzw. auf der Stirnfläche die Anzahl der Streifenbürsten und der Schleifgewebeabschnitte erhöht wird. Dadurch wird ein wesentlich besseres Schleifergebnis erzielt.The grooves are expediently arranged in the base body according to a scheme. So it is advantageous if the grooves with the different depths alternate are arranged, since there is then the possibility that the angular distances be reduced between the grooves compared to the known designs, so that on the circumference or on the end face the number of strip brushes and Abrasive cloth sections is increased. This will make a much better one Grinding result achieved.

Es ist davon auszugehen, daß die Anzahl der Schleifgewebeabschnitte und der Streifenbürsten um ca. 40 % erhöht werden kann. Außerdem können sie bei Bestückung der Stirnfläche des Grundkörpers strahlenförmig angeordnet werden, wodurch der Einsatz in Bearbeitungszentren erleichtert wird. Gemäß einer weiteren Ausführung ist vorgesehen, daß der gegenüber der Umfangs- oder der Stirnfläche des Grundkörpers vorstehende Bereich des Fußes in einem Bogen verläuft. Der an diesem Bereich befestigte Schleifgewebeabschnitt wird dann entsprechend geformt. Die Verformbarkeit der Streifenbürsten ist zwar begrenzt, jedoch verformen sich die Schleifgewebeabschnitte stärker. Durch diese Gestaltung wird der Einsatzbereich der Schleifbürsten erweitert, da die Gefahr einer Beschädigung des zu schleifenden Bauteiles wesentlich vermindert wird und der Verschleiß der Schleifgewebeabschnitte verringert wird, da die stoßartige Belastung beim Kontakt mit dem zu schleifenden Bauteil verringert wird. Der Bogen kann von der Krümmung her und auch vom Krümmungsverlauf her beliebig gestaltet werden. Vorzugsweise ist er jedoch so geformt, daß die äußeren Ränder in einem größeren Abstand zur zugeordneten Streifenbürste stehen als der mittlere Bereich. Unabhängig von der Gestaltung der Schleifbürste sind die Sch!eifgewebeabschnitte zumindest im äußeren, dem flexiblen Fuß abgewandten Bereich mit Längseinschnitten versehen.It can be assumed that the number of abrasive cloth sections and the Strip brushes can be increased by approximately 40%. You can also go to The end face of the base body can be arranged in a radiation pattern, which makes it easier to use in machining centers. According to another Execution is provided that opposite the circumferential or the end face of the base protruding area of the foot runs in an arc. The one abrasive cloth section attached to this area is then shaped accordingly. The deformability of the strip brushes is limited, but they deform Abrasive cloth sections stronger. The design of the Grinding brushes expanded because of the risk of damage to the grinded Component is significantly reduced and the wear of the abrasive cloth sections is reduced because the impact load on contact with the grinding Component is reduced. The bow can be from the curvature and also from Curvature course can be designed arbitrarily. However, it is preferably shaped so that the outer edges at a greater distance from the assigned strip brush stand as the middle area. Regardless of the design of the Abrasive brush are the abrasive cloth sections at least in the outer, the flexible Provide longitudinal incisions in the area facing away from the foot.

Die erfindungsgemäßen Schleifbürsten werden auch zur Bearbeitung von Profilleisten der unterschiedlichsten Querschnitte verwendet. Die Gestaltung der Streifenbürsten und der Schleifgewebeabschnitte richtet sich dann nach den Querschnitten der Profilleisten. Für eine derartige Ausführung ist vorgesehen, daß der flexible Fuß sich bis in den Bereich des äußeren freien Randes der zugehörigen Schleifbürste erstreckt, und daß der Schleifgewebeabschnitt an dem äußeren freien Rand des flexiblen Fußes festgelegt ist. Da bei dieser Ausführung die äußere Kontur der Streifenbürste und die daran angepaßte Kontur des Schleifgewebeabschnittes auf den Querschnitt einer Profilleiste bezogen bzw. daran angepaßt ist, ist bei dieser Ausführung vorgesehen, daß zwischen der Borstenreihe der Streifenbürste und dem flexiblen Fuß ein vorzugsweise an der Borstenreihe festgelegtes Stützkissen vorgesehen ist. Dieses Stützkissen liegt dann in Umlaufrichtung der Schleifbürste gesehen, vor der Streifenbürste. Dadurch wird die Schleifwirkung erhöht, da sich das Stützkissen nicht so stark verformen läßt wie die Streifenbürste.The grinding brushes according to the invention are also used for machining Profiles of different cross sections used. The design of the Strip brushes and the abrasive cloth sections then depend on the Cross sections of the profile strips. For such an embodiment it is provided that the flexible foot extends into the area of the associated outer free edge Abrasive brush extends, and that the abrasive cloth section on the outer free Edge of the flexible foot is set. Because in this version the outer contour the strip brush and the contour of the abrasive cloth section adapted to it is related to the cross section of a profile strip or is adapted to this Execution provided that between the row of bristles of the strip brush and the flexible foot a support cushion, preferably fixed to the row of bristles is provided. This support cushion then lies in the direction of rotation of the grinding brush seen in front of the strip brush. This increases the grinding effect, since the Does not deform the support cushion as much as the strip brush.

Zweckmäßigerweise besteht das Stützkissen aus Moosgummi oder einem ähnlichen elastisch verformbaren Material. Unabhängig von der Ausgestaltung der Schleifbürste können in besonders vorteilhafter Weise die Schleifgewebeabschnitte und die Streifenbürsten als Profilelemente ausgebildet sein, um sie an die unterschiedlichen Querschnitte der zu bearbeitenden Gegenstände anzupassen.The support cushion is expediently made of foam rubber or the like elastically deformable material. Regardless of the design of the Abrasive brushes can be used in a particularly advantageous manner the abrasive cloth sections and the strip brushes can be designed as profile elements to attach them to the adapt different cross-sections of the objects to be processed.

Die in den Figuren 1 und 2 dargestellten Schleifbürsten 10 bestehen im wesentlichen aus einem metallischen Grundkörper 11, einer Vielzahl von Streifenbürsten 12 und einer entsprechenden Stückzahl von Schleifgewebeabschnitten 13, die zwischen den Streifenbürsten 12 angeordnet sind, so daß die in Drehrichtung hinter den Schleifgewebeabschnitten 13 liegenden Streifenbüsten 12 der Abstützung dienen. Ein Vergleich der Figuren 1 und 2 zeigt, daß der Außendurchmesser des metallischen Grundkörpers 11 bei der stirnseitigen Anordnung der Streifenbürsten 12 deutlich größer ist als bei der Anordnung auf der Umfangsfläche.
