Description
Beim Einbringen von Löchern, Ausnehmungen und dergleichen, insbesondere durch Stanzen, Laserschneiden, Plasmaschneiden oder Brennschneiden, in Stahlblech, das durchaus einige Millimeter dick sein kann, bilden sich störende Grate. Diese können mittels spezieller Bürsten maschinell entfernt bzw. abgeschliffen werden.When introducing holes, recesses and the like, in particular by punching, laser cutting, plasma cutting or flame cutting, in sheet steel, which may well be a few millimeters thick, disturbing burrs form. These can be mechanically removed or abraded by means of special brushes.
Bekannt sind Entgratmaschinen mit horizontal umlaufenden Riemen, die eine Vielzahl nebeneinander angeordneter Bürsten als Schleifbesatz tragen. Diese Bürsten bestehen vorzugsweise aus einem fächerartigen Paket von Schleifpapier und/oder Schleifvlies. Das zu entgratende Werkstück wird quer zur Bewegungsrichtung der Bürsten vorgeschoben. Dabei streichen die Ränder der Schleifpapiere bzw. Schleifvliese quer zur Vorschubrichtung des Werkstücks über dessen Oberfläche und entfernen dadurch die überstehenden Grate. Wichtig ist eine gewisse Flexibilität der Bürsten, so dass diese eine Stück weit in die ausgeschnittenen Ausnehmungen eindringen können.Deburring machines with horizontally circulating belts are known, which carry a large number of juxtaposed brushes as a grinding stock. These brushes preferably consist of a fan-like package of sandpaper and / or abrasive fleece. The workpiece to be deburred is fed transversely to the direction of movement of the brushes. The edges of the abrasive papers or abrasive nonwoven cross over the feed direction of the workpiece over its surface and thereby remove the protruding burrs. Important is a certain flexibility of the brushes, so that they can penetrate a little way into the cut-out recesses.
Aufgrund des mechanischen Abriebs verschleißen die Bürsten relativ schnell. In regelmäßigen Abständen müssen deshalb die Bürsten ausgetauscht werden. Je mehr Bürsten nebeneinander angeordnet sind, desto teurer und aufwendiger ist der Austausch.Due to the mechanical abrasion wear the brushes relatively quickly. At regular intervals, therefore, the brushes must be replaced. The more brushes are arranged side by side, the more expensive and expensive the replacement.
Bei den herkömmlichen Maschinen ist der Austausch der verschlissenen Bearbeitungselemente umständlich und zeitraubend, denn die Bearbeitungselemente müssen von dem Band oder Riemen, auf dem sie befestigt sind, abgeschraubt werden. Anschließend müssen neue bzw. erneuerte Bürsten montiert werden. Je breiter die Maschine ist, desto länger ist der mit Bearbeitungseinheiten bestückte Riemen, und es müssen dementsprechend viele Bearbeitungseinheiten demontiert und wieder anmontiert werden. Der komplette Austausch eines Bürstensatzes kann deshalb mehrere Stunden dauern. Zudem besteht die Gefahr, dass eine Bearbeitungseinheit oder Bürste nicht korrekt montiert wird, so dass sie sich im Betrieb lockert oder gar abfällt. Schrauben und Gewinde sind überdies verschleißanfällig.In the conventional machines, the replacement of the worn processing elements is cumbersome and time-consuming, because the processing elements must be unscrewed from the band or strap on which they are attached. Subsequently, new or renewed brushes must be mounted. The wider the machine, the longer the belt equipped with machining units, and correspondingly many machining units have to be dismantled and reassembled. The complete replacement of a brush set can therefore take several hours. In addition, there is a risk that a processing unit or brush is not mounted correctly, so that it loosens during operation or even drops. Screws and threads are also susceptible to wear.
Das der Erfindung zugrunde liegende Problem besteht also darin, bei einer Maschine mit den Merkmalen des Oberbegriffs von Patentanspruch 1 die dem Verschleiß unterliegenden Bearbeitungseinheiten so an dem bzw. den umlaufenden Treibriemen lösbar zu befestigen, dass ein schneller und einfacher Austausch möglich ist, dass die Halterung den hohen mechanischen Beanspruchungen im Betrieb standhält, und dass speziell die verschleißenden Teile kostengünstig herstellbar sind.The problem underlying the invention is therefore, in a machine with the features of the preamble of claim 1, the wear-resistant machining units so releasably fasten to the or the rotating belt that a quick and easy replacement is possible that the holder Withstand the high mechanical stresses during operation, and that especially the wear parts are inexpensive to produce.
Die gestellte Aufgabe wird gelöst durch die kennzeichnenden Merkmale des ersten Patentanspruchs.The stated object is achieved by the characterizing features of the first claim.
Erfindungsgemäß sind an den endlos umlaufenden Treibriemen Bürstenhalter befestigt, die eine Stecklasche aufweisen. Die Bürstenträger, die den Schleifbesatz tragen, sind auf die Stecklaschen der Bürstenhalter formschlüssig aufschiebbar und verrasten in ihrer Endposition selbsttätig. Bevorzugt sind die Bürstenhalter als flache L-förmige Befestigungswinkel ausgebildet, wobei ein Schenkel mit dem Treibriemen fest verbunden und der andere Schenkel nach außen abgewinkelt ist, vorzugsweise annähernd rechtwinklig. Dabei bildet das freie Ende des abgewinkelten Schenkels die Stecklasche.According to the brush holder are attached to the endless peripheral drive belt, which have a tab. The brush holder, which carry the sanding, are positively pushed onto the tabs of the brush holder and lock in their final position automatically. Preferably, the brush holder are formed as a flat L-shaped mounting bracket, one leg is firmly connected to the drive belt and the other leg is angled outwards, preferably approximately at right angles. The free end of the angled leg forms the insertion flap.
Die Bürstenträger können einfach von Hand auf die Bürstenhalter aufgeschoben werden. Für die Montage ist kein Werkzeug notwendig, insbesondere müssen keine Schrauben gelöst und wieder angezogen werden. Aufgrund der formschlüssigen Verbindung zwischen Bürstenträger und Bürstenhalter und der selbsttätigen Verrastung sitzen die Bürstenträger fest und sicher auf den Bürstenhaltern und können sich im laufenden Betrieb nicht lockern oder gar lösen. Zur Demontage muss einfach nur die Verrastung gelöst und anschließend der Bürstenträger von der Stecklasche des Bürstenhalters abgezogen werden. Der Austausch der Bürsten erfordert deshalb nur noch einen Bruchteil der Zeit im Vergleich zu herkömmlichen Maschinen mit aufgeschraubten oder anderweitig befestigten Bearbeitungselementen. Durch den Entfall zusätzlicher Befestigungsmittel wie insbesondere Schrauben, Muttern oder Gewinde lassen sich vor allem die Bürstenträger kostengünstig als Einmalartikel herstellen.The brush holders can simply be pushed onto the brush holders by hand. No tools are necessary for the assembly, in particular no screws have to be loosened and tightened again. Due to the positive connection between the brush holder and brush holder and the automatic latching sit the brush holder firmly and securely on the brush holders and can not loosen or even solve during operation. To disassemble, simply release the catch and then remove the brush holder from the tab of the brush holder. The replacement of the brushes therefore requires only a fraction of the time compared to conventional machines with screwed or otherwise fastened processing elements. By eliminating additional fasteners such as particular screws, nuts or threads especially the brush holder can be produced inexpensively as a disposable item.
Vorzugsweise weisen die als Befestigungswinkel ausgebildeten Bürstenhalter im Bereich der Abwinkelung eine Ausnehmung auf, welche eine Rastkante bildet, und weisen die Bürstenträger eine federnde Rastzunge auf, welche beim Aufschieben die Ausnehmung des Bürstenhalters durchsetzt und bei Erreichen der Endposition dessen Rastkante hintergreift. Eine solche federnde Rastzunge hat den Vorteil, dass sie aufgrund der Federwirkung leicht und sicher selbsttätig einrastet, sobald die korrespondierende Rastkante hintergriffen wird. Umgekehrt lässt sich eine solche Rastzunge sehr leicht wieder entrasten, indem sie gegen die Federkraft gedrückt wird, um den Hintergriff der Rastkante aufzuheben und es dadurch zu ermöglichen, den Bürstenträger ohne weiteres von dem Bürstenhalter abzuziehen.Preferably, the brush holder designed as a fastening angle in the region of the bend has a recess which forms a latching edge, and the brush holder on a resilient latching tongue, which passes through the recess of the brush holder when pushed and engages behind the locking edge when reaching the end position. Such a resilient latching tongue has the advantage that it easily and safely automatically engages due to the spring action, as soon as the corresponding locking edge is engaged behind. Conversely, such a latching tongue can very easily be unlatched again by being pressed against the spring force in order to release the rear grip of the latching edge and thereby make it possible to easily pull the brush holder away from the brush holder.
Bei einer besonders bevorzugten Ausführungsform bildet der Rand der Ausnehmung des Befestigungswinkels eine Rastnase, und hat die Rastzunge eine Aussparung, in welche diese Rastnase bei Erreichen der Endposition einschnappt. Die Rastkante ist in diesem Fall eine Hinterkante der Rastnase. Es sind jedoch auch andere Rastmittel wie zum Beispiel Kerben, Vorsprünge, Keile oder federbelastete Elemente denkbar, mit deren Hilfe der Bürstenträger bei Erreichen seiner Endposition auf dem Befestigungswinkel selbsttägig verrastet.In a particularly preferred embodiment, the edge of the recess of the mounting bracket forms a latching nose, and the latching tongue has a recess into which this latching nose snaps when reaching the end position. The locking edge is in this case a trailing edge of the latch. However, there are also other locking means such as notches, projections, wedges or spring-loaded elements conceivable by means of which the brush holder locked on reaching the final position on the mounting bracket on a daily basis.
Das Lösen der Verrastung wird erleichtert, wenn das frei federnde Ende der Rastzunge eine Druckfläche aufweist, auf die mit einem oder zwei Fingern gedrückt werden kann, um die Rastzunge um ein ausreichendes Maß zu biegen.The release of the latching is facilitated if the free resilient end of the latching tongue has a pressure surface which can be pressed with one or two fingers to bend the latching tongue by a sufficient amount.
Der Bürstenträger hat vorteilhaft eine Grundplatte mit einer im Wesentlichen ebenen Unterseite, auf welcher der dem Verschleiß unterliegende Schleifbesatz aufgebracht ist. Die Unterseite kann einen umlaufenden überhöhten Rand aufweisen. Der Schleifbesatz besteht vorzugsweise aus einem Paket von Schleifpapieren und/oder Schleifvliesen. Diese lassen sich gut auf die ebene Unterseite aufkleben, um zusammen mit dem Bürstenträger eine Art Bürste zu bilden. Solche Bürsten haben gegenüber flächigen Schleifmitteln wie zum Beispiel Schleifklötze den Vorteil, dass sie flexibel sind und somit ein Stück weit in Ausnehmungen des Werkstücks eindringen können, um störende Grate nicht nur an der Oberseite bzw. Unterseite des Werkstücks zu entfernen, sondern auch die Kanten der Ausnehmungen bzw. Löcher zu verrunden.The brush holder advantageously has a base plate with a substantially flat underside, on which the wear underlying grit is applied. The underside may have a circumferential raised edge. The abrasive stock preferably consists of a package of abrasive papers and / or abrasive webs. These can be glued well on the flat bottom to form a brush with the brush holder. Such brushes have the advantage over flat abrasives such as sanding blocks that they are flexible and thus can penetrate a little way into recesses of the workpiece to remove bothersome burrs not only at the top and bottom of the workpiece, but also the edges of the Fillet recesses or holes.
In bevorzugter und vorteilhafter Ausführung ist der Bürstenträger einstückig aus Kunststoff hergestellt, beispielsweise durch Spritzgießen. Damit wird der Bürstenträger nicht nur sehr kostengünstig in der Herstellung, sondern hat auch eine Reihe weiterer vorteilhafter Eigenschaften: Die formschlüssige Steckverbindung zwischen Bürstenhalter und Bürstenträger lässt sich optimal realisieren, wenn der Bürstenträger aus Kunststoff besteht, der L-förmige Bürstenhalter dagegen aus Metall. Aufgrund der begrenzten Nachgiebigkeit und Elastizität des Kunststoffs ist ein fester Sitz des Bürstenträgers auf dem Bürstenhalter selbst dann gewährleistet, wenn beide Teile mit Toleranz hergestellt wurden. Vor allem aber gleitet Kunststoff gut auf Metall, so dass sowohl das Aufstecken wie auch das Abziehen des Bürstenträgers auf bzw. von dem Bürstenhalter keine Probleme bereitet. Schließlich lassen sich in spritzgegossenem Kunststoff auch komplizierte Formen leicht realisieren.In a preferred and advantageous embodiment of the brush holder is integrally made of plastic, for example by injection molding. Thus, the brush holder is not only very inexpensive to manufacture, but also has a number of other advantageous properties: The positive connection between brush holder and brush holder can be optimally realized when the brush holder is made of plastic, the L-shaped brush holder, however, made of metal. Due to the limited compliance and elasticity of the plastic, a firm fit of the brush holder on the brush holder is guaranteed even if both parts have been manufactured with tolerance. Above all, plastic slides well on metal, so that both the plugging as well as the removal of the brush holder on or from the brush holder no problems. After all, complicated shapes can be easily realized in injection-molded plastic.
Vorteilhaft weist der Bürstenträger zwei Halteprofile auf, welche auf der Grundplatte ausgebildet sind und sich in Aufschubrichtung erstrecken. Die Halteprofile bilden Nutenschlitze, die gegeneinander weisen, um die Ränder der Stecklasche aufzunehmen.Advantageously, the brush holder on two retaining profiles, which are formed on the base plate and extending in the direction of extension. The retaining profiles form slot slots facing each other to receive the edges of the tab.
Sowohl die Nutenschlitze zur Aufnahme der Stecklasche als auch die federnde Rastzunge lassen sich im Spritzgussverfahren sehr gut ausbilden, so dass insgesamt ein präzises und stabiles Formteil kostengünstig hergestellt werden kann. Ist der Schleifbesatz, also das Paket von Schleifpapieren und/oder Schleifvliesen verschlissen, kann einfach die gesamte Bürsteneinheit einschließlich des Bürstenträgers ausgetauscht werden. Die einmalige Verwendung des Bürstenträgers fällt kostenmäßig kaum ins Gewicht, hat aber den Vorteil, dass die für die mechanische Zuverlässigkeit entscheidende Verbindung zwischen Bürstenträger und Bürstenhalter jeweils durch ein fabrikneues Teil hergestellt wird.Both the slot slots for receiving the plug-in tab and the resilient latching tongue can be formed very well by injection molding, so that overall a precise and stable molded part can be produced inexpensively. If the sanding stock, so the package of abrasive papers and / or abrasive fleece worn, just the entire brush unit including the brush holder can be replaced. The one-time use of the brush holder is in terms of cost barely in the weight, but has the advantage that the crucial for mechanical reliability connection between the brush holder and brush holder is made by a brand new part.
