Description

Die Erfindung betrifft eine Kopfbürste mit einer Vielzahl von Schleifborstenbündeln, welche als Besatzmaterial mit ihrem einen Ende in einer Grundplatte gehalten sind und mit ihrem anderen Ende die Besatzoberfläche der Kopfbürste bilden.The invention relates to a head brush with a variety of Grinding bristle bundles, which are used as fill material with their one end are held in a base plate and with their at the other end form the trim surface of the head brush.

Kopfbürsten als solche sind hinlänglich bekannt. Es wurde das Entgraten von Autofelgen und insbesondere Aluminiumfelgen in der Vergangenheit manuell mit Feilen durchgeführt. Die Entgratung war notwendig, um die nach den Gießprozessen der Aluminiumfelgen stehengebliebenen Grate zu entfernen. Zum Einsatz kamen auch topfförmige Schleifwerkzeuge mit Schleifgewebelamellen. Diese Versuche zeigten jedoch keine brauchbaren Ergebnisse.Head brushes as such are well known. It did Deburring car rims and especially aluminum rims in the past performed manually with files. The deburring was necessary to the after the casting process of the aluminum rims to remove stuck burrs. For use came pot-shaped grinding tools with abrasive cloth flaps. However, these attempts showed no useful results.

Weitere Versuche zum Entgraten von Aluminiumfelgen wurden mit sogenannten Topfbürsten, die auf Holz- oder Kunststoffgrundplatten befestigt waren, durchgeführt. Diese Topfbürsten wiesen als Besatzmaterial Schleifborsten auf. Allerdings wurden auch diese Topfbürsten den hohen Anforderungen der Felgenhersteller nicht gerecht.Further attempts to deburr aluminum rims were carried out So-called pot brushes, which are on wooden or plastic base plates were attached. These pot brushes pointed grinding bristles as fill material. However These cup brushes also meet the high demands of the rim manufacturers not fair.

Bekannt war auch der Einsatz von Kopfbürsten, die mit Schleifborstenbündeln einer Dimension und einer Länge bestückt waren. Die Bestückung war hierbei über die Besatzoberfläche relativ gleichmäßig verteilt, d. h., daß die Schleifborstenbündel allesamt etwa gleichlang aus der Oberfläche der Grundplatte herausragten. Auch mit solchen Kopfbürsten waren nicht optimale Entgratungsergebnisse erreichbar.The use of head brushes with bundles of grinding bristles was also known one dimension and one length. The placement was relative across the trim surface evenly distributed, d. that is, the grinding bristle bundle all about the same length from the surface of the base plate stood out. Even with such head brushes were not optimal Deburring results attainable.

Hier setzt die vorliegende Erfindung an.This is where the present invention comes in.

Die Erfindung hat das Ziel, die eingangs genannte Kopfbürste so weiterzubilden, daß diese bei der Entgratung von topfförmigen Gegenständen und insbesondere bei der Entgratung von Aluminiumfeigen optimale Arbeitsergebnisse zeigt und dies ab der Bearbeitung der ersten Feige. Ein weiteres Ziel der Erfindung besteht darin, eine verbesserte Entgratungseinrichtung für die Entgratung von Autofelgen anzugeben.The aim of the invention is the head brush mentioned at the beginning so that they can be used to deburr pot-shaped Objects and especially when deburring aluminum figs shows optimal work results and this from Processing the first fig. Another object of the invention is an improved deburring device for to specify the deburring of car rims.

Dieses Ziel wird für die Kopfbürste durch die Merkmale des Anspruchs 1 und für die Entgratungseinrichtung durch die Merkmale des Anspruchs 14 gelöst.This goal is achieved for the head brush by the characteristics of the Claim 1 and for the deburring device by the features of claim 14 solved.

Demnach ist für die erfindungsgemäße Kopfbürste wesentlich, daß die Besatzoberfläche profiliert ist, wobei die Profilierung der Besatzoberfläche derart gewählt ist, daß der äußere Kopfbürstenrand ein abgerundetes Profil mit dem Radius R aufweist.It is therefore essential for the head brush according to the invention that that the facing surface is profiled, the profiling the facing surface is chosen such that the outer Head brush edge has a rounded profile with radius R.

In einer Weiterbildung dieser Kopfbürste ist vorgesehen, daß mindestens ein Teil der Schleifborstenbündel geneigt aus der Grundplatte herausragt. Diese Weiterbildung wird vorzugsweise zusammen mit der oben erwähnten Profilierung der Besatzoberfläche angewandt, ist jedoch nicht zwingend hierzu.In a further development of this head brush it is provided that at least a part of the grinding bristle bundle inclined from the Base plate protrudes. This training is preferred together with the above-mentioned profiling of the trim surface applied, but is not mandatory for this.

Die Neigung der Schleifborstenbündel kann zwischen etwa 5° und etwa 45° bezogen auf eine orthogonal von der Grundplattenebene herausragende Achse sein. Die Neigung dient auch dazu, daß nebeneinander angeordnete Schleifborstenbündel sich durch deren Berührung gegenseitig stützen.The inclination of the grinding bristle bundle can be between about 5 ° and about 45 ° in relation to an orthogonal of the base plate level outstanding axis. The inclination also serves that abrasive bristle bundles arranged side by side through support each other's touch.

In einer Weiterbildung der Erfindung sind einige der Schleifborstenbündel mit einem geringeren Durchmesser als die übrigen Schleifborstenbündel versehen. Schließlich können die Borsten mindestens einiger Schleifborstenbündel unterschiedlich lang ausgestaltet sein.In a further development of the invention, some of the grinding bristle bundles are with a smaller diameter than the rest Provide abrasive bristle bundle. Finally, the bristles at least some grinding bristle bundles of different lengths be designed.

In einer anderen Weiterbildung ist vorgesehen, daß die Schleifborstenbündel in geeigneten Öffnungen, die in der Grundplatte eingearbeitet sind, sitzen. Zweckmäßigerweise sind die in diese Öffnungen ragenden Enden der Schleifborstenbündel von Kunstharz umgeben. Hierfür ist ein flexibel aufbaubares Kunstharzfundament für die Borstenbefestigung auf der Grundplatte angeordnet.Another development provides that the Abrasive bristle bundles in suitable openings in the Base plate are incorporated, sit. Are expedient the ends of the grinding bristle bundles protruding into these openings surrounded by synthetic resin. For this is a flexibly buildable Resin foundation for bristle attachment to the base plate arranged.

Die erfindungsgemäße Kopfbürste zeichnet sich dadurch aus, daß für jede Einsatzzone bei der Entgratung von Aluminiumfelgen die Bestückung der Kopfbürste angepaßt ist. Dies wird durch die Neigung einiger der Schleifenborstenbündel und die erwähnte Profilierung der Besatzoberfläche sowie durch die Abstützng der Schleifborsten gegeneinander erreicht und gegebenfalls durch das erwähnte flexibel aufbaubare Kunstharzfundament auf der Grundplatte für die Borstenbefestigung unterstützt. Zusätzlich kann durch eine Schleifborstenlängendifferenzierung der für die Entgratung erforderliche Anpreßdruck optimal an die Anforderungen angepaßt werden.The head brush according to the invention is characterized in that for every application zone when deburring aluminum rims the equipment of the head brush is adapted. This is through the slope of some of the loop bristle bundles and the one mentioned Profiling of the trim surface and through the support the grinding bristles reached against each other and if necessary thanks to the flexibly buildable synthetic resin foundation supports the base plate for the bristle attachment. In addition can be done by differentiating the length of the grinding bristles optimally the contact pressure required for deburring the requirements are adjusted.

Ein zusätzliches Differenzieren über Borstenmaterial, Borstenprofil Kornart und Korngröße der Schleifborsten führt ebenfalls zu Verbesserungen der Arbeitsleistung der mit einer solchen Kopfbürste bestückten Entgratungswerkzeuge.An additional differentiation via bristle material, bristle profile Grain type and grain size of the grinding bristles also leads to improve the work performance of those with a deburring tools equipped with such a head brush.

Je nach zu bearbeitender Felgentype (Durchmesser, Breite, Radialsteggestaltung usw.) wird eine optimal an diesen Felgentyp angepaßte Kopfbürste auf die Entgratungseinrichtung gesetzt, so daß ein optimales Entgratungsergebnis von der ersten Felge an möglich ist.Depending on the type of rim to be machined (diameter, width, Radial web design etc.) will be optimal for this type of rim adapted headbrush placed on the deburring device, so that an optimal deburring result from the first Rim on is possible.

Die Entgratungseinrichtung für Autofelgen zeichnet sich dadurch aus, daß die erfindungsgemäße Kopfbürste sowie eine Antriebseinrichtung vorgesehen wird, durch welche die Kopfbürste rotierend in die topfförmige Öffnung der Autofelge einführbar ist. Die Autofelge ist vorzugsweise eine Aluminiumfelge.The deburring device for car rims is characterized by this from that the head brush according to the invention and a Drive device is provided through which the head brush Can be rotated into the cup-shaped opening of the car rim is. The car rim is preferably an aluminum rim.

Dank des Einsatzes der erfindungsgemäßen Kopfbürste sind verhältnismäßig kurze Bearbeitungszeiten zur Entgratung von Aluminiumfelgen möglich. Zusätzlich wird ein günstiges Preis-Leistungsverhältnis bei gleichmäßiger Produktqualität erzielt, so daß der Einsatz einer solchen Entgratungseinrichtung für den Felgenhersteller gegenüber den bisher vorgenommenen manuellen Entgratungsmaßnahmen zweckmäßig und sinnvoll ist.Thanks to the use of the head brush according to the invention are proportionate short machining times for deburring Aluminum rims possible. In addition, a good price-performance ratio achieved with uniform product quality, so that the use of such a deburring device for the rim manufacturer compared to the previous manual Deburring measures are expedient and sensible.

In den nachfolgenden Figuren bezeichnen, sofern nicht anders angegeben, gleiche Bezugszeichen gleiche Teile mit gleicher Bedeutung.Designate in the following figures, unless otherwise indicated, same reference numerals, same parts with the same Importance.

In Figur 1 ist das Ausführungsbeispiel einer Kopfbürste 1 nach der Erfindung dargestellt. Die Kopfbürste 1 weist eine runde Grundplatte 2 auf. Diese Grundplatte 2 verfügt an ihrer oberen Fläche über eine Vielzahl von kreisförmigen Öffnungen 20, in die Schleifborstenbündel 10, 11 unterschiedlicher Durchmesser eingesetzt sind. Die Schleifborstenbündel 10, 11 bilden das Besatzmaterial 3 der Kopfbürste 1 und sind im vorliegenden Beispiel kreisringförmig angeordnet.The exemplary embodiment of a head brush 1 is shown in FIG presented the invention. The head brush 1 has a round one Base plate 2 on. This base plate 2 has at its top Area over a plurality of circular openings 20, in the grinding bristle bundles 10, 11 of different diameters are used. The grinding bristle bundles 10, 11 form that Trim material 3 of the head brush 1 and are in the present Example arranged in a ring.

Die Schleifborstenbündel 10, 11 weisen unterschiedliche Durchmesser auf, wobei die einzelnen Schleifborsten 10 des weiteren unterschiedlich lang ausgebildet sein können.The grinding bristle bundles 10, 11 have different Diameter, the individual grinding bristles 10 des others can be of different lengths.

Wesentlich bei der dargestellten Kopfbürste 1 ist die profilierte Gestaltung der Besatzoberfläche 4. Die Besatzoberfläche 4 ist nämlich, was insbesondere aus Figur 2 deutlich zu erkennen ist, mit einer Radius R und damit mit einer Abrundung am Außenrand der Kopfbürste 1 versehen. Der Radius R ist zweckmäßigerweise optimal an den Innenradius der zu bearbeitenden Autofelge angepaßt. Dieser Radius R der Kopfbürste 1 kann beispielsweise den gleichen oder annähernd gleichen Radius aufweisen wie die Autofelge an ihrer topfförmigen Innenkontur, die zu entgraten ist.The profiled head brush 1 is essential Design of the trim surface 4. The trim surface 4 is namely what can be clearly seen in particular from Figure 2 is, with a radius R and thus with a rounding on Provide the outer edge of the head brush 1. The radius R is expedient optimally to the inner radius of the machined Car rim adjusted. This radius R of the head brush 1 can for example the same or approximately the same radius have like the car rim on its cup-shaped inner contour, to be deburred.

Obwohl im dargestellten Ausführungsbeispiel eine Profilierung der Besatzoberfläche 4 durch den äußeren Radius R gezeigt ist, ist die Erfindung hierauf nicht beschränkt. Vielmehr liegt eine Profilierung, die von einer geraden Linie L bzw. geraden Ebene der Besatzoberfläche 4 abweicht im Rahmen der Erfindung. So kann die Kopfbürste 1 z. B. auch am Innenrand eine überhöhte Länge aufweisen.Although a profiling in the illustrated embodiment the facing surface 4 is shown by the outer radius R, the invention is not limited to this. Rather lies a profiling by a straight line L or straight The level of the stocking surface 4 deviates within the scope of the invention. So the head brush 1 z. B. also an excessive on the inner edge Have length.

Wie darüber hinaus aus Figur 2 weiter erkennbar, sind die am Außenrand stehenden Schleifborstenbündel 10 so geneigt, daß sich der Durchmesser des Besatzmaterials 3 von der Oberfläche der Grundplatte 2 in Richtung der Besatzoberfläche 4 etwas erweitert bis der Radius R beginnt. Die am Außenrand der Kopfbürste 1 befindlichen Schleifborstenbündel 10 ragen also nach außen. Dies kann in einem Neigungsgrad von etwa 5° bis 30° der Fall sein.As can also be seen from FIG. 2, the Standing edge bristle bundle 10 inclined so that the diameter of the trim material 3 from the surface the base plate 2 in the direction of the facing surface 4 somewhat extended until the radius R begins. The one on the outer edge of the head brush 1 located grinding bristle bundle 10 thus protrude Outside. This can be done in a degree of inclination of about 5 ° to 30 ° Case.

Bei der dargestellten Kopfbürste 1 sind auch die am Innenrand angeordneten Schleifborstenbündel 11 geneigt, aber in entgegengesetzte Richtung wie die am Außenrand der Kopfbürste 1 befindlichen Schleifborstenbündel. Der Neigungswinkel ist in Figur 2 mit den Bezugszeichen W angegeben. Die genannten Neigungswinkel 5° bis 30° sind auf eine orthogonal. aus der Grundplattenebene herausragende, gedachte Achse X bezogen.In the head brush 1 shown, there are also those on the inner edge arranged brush bristle bundle 11 inclined, but in opposite Direction like that on the outer edge of the head brush 1 located grinding bristle bundle. The angle of inclination is in Figure 2 indicated with the reference symbol W. The angles of inclination mentioned 5 ° to 30 ° are orthogonal. from the baseplate level outstanding, imaginary axis X related.

Obwohl die einzelnen Schleifborstenbündel 10, 11 klemmend in den erwähnten Öffnungen 20 der Grundplatte 2 sitzen können, ist es zweckmäßig, in diesen Öffnungen Kunstharz 30 einzufüllen, um eine bessere Fixierung der Schleifborstenbündel 10, 11 zu erreichen. Although the individual grinding bristle bundles 10, 11 are jammed in can sit the mentioned openings 20 of the base plate 2, it is expedient to fill synthetic resin 30 into these openings, to better fix the grinding bristle bundles 10, 11 to reach.

Auf der dem Besatzmaterial 3 gegenüberliegenden Seite ist die Grundplatte 2 mit einer Befestigungseinrichtung 21, hier einer Öffnung, versehen. In diese Öffnung kann ein Verbindungsteil eingeklemmt oder eingeschraubt werden, welches mit einer Antriebswelle einer Antriebseinrichtung einer Entgratungsmaschine in Verbindung steht. Bei rotierender Antriebseinrichtung wird die Kopfbürste dann in Drehung versetzt, so daß eine Entgratung der Autofelge möglich ist, wenn die Kopfbürste rotierend in die topfförmige Öffnung der Autofelge eingeführt und dort hin- und herbewegt wird.On the side opposite the trim material 3 is the Base plate 2 with a fastening device 21, here one Opening. A connecting part can be inserted into this opening be clamped or screwed in, which with a drive shaft a drive device of a deburring machine communicates. With rotating drive device the head brush is then rotated so that a Deburring the car rim is possible when using the head brush rotatingly inserted into the cup-shaped opening of the car rim and being moved back and forth there.

Als Schleifborsten können Filamente mit einem Trägermaterial als Polyamid, insbesondere Polyamid 6 und Polyamid 612, vorgesehen werden. Dieses Trägermaterial weist vorzugsweise eine Schleifkörnung aus Aluminiumoxid oder Siliziumkarbid auf in einem Anteil von vorwiegend 30% in den Korngrößen 46 bis 500. Für die Entgratung von Aluminiumfelgen ist es zweckmäßiger Aluminiumoxid als Körnung zu verwenden, da dieses im Vergleich zu Siliziumkarbid widerstandsfähiger ist und nicht so leicht bricht. Des weiteren hat sich herausgestellt, daß die Entgratung von Aluminium-Autofelgen mit dem Einsatz von Bürsten, die Schleifborsten mit einer Körnung aus Aluminiumoxid aufweisen, glattere Oberflächen ergeben.Filaments with a carrier material can be used as grinding bristles as polyamide, in particular polyamide 6 and polyamide 612 become. This carrier material preferably has one Aluminum oxide or silicon carbide abrasive grain on in predominantly 30% in grain sizes 46 to 500. It is more appropriate for deburring aluminum rims Use alumina as the grain, as this compares is more resistant to silicon carbide and not as light breaks. Furthermore, it has been found that deburring of aluminum car rims with the use of brushes, which have abrasive bristles with a grain of aluminum oxide, result in smoother surfaces.

Die Entgratungseinrichtung ist auch zur Bearbeitug von anderen topfförmigen Gegenständen als Autofelgen geeignet. The deburring device can also be used by others Pot-shaped objects suitable as car rims.
