Description

Die Erfindung betrifft eine Vorrichtung zum Bearbeiten eines band- oder plattenförmigen metallischen Werkstücks, mit wenigstens einer mit Bearbeitungselementen versehenen umlaufenden Fördereinrichtung, wobei die Fördereinrichtung die Bearbeitungselemente schräg bzw. quer zur Vorschubrichtung des Werkstücks im Bereich des zu bearbeitenden Werkstücks wenigstens annähernd linear vorbeiführt.The invention relates to a device for processing a strip-shaped or plate-shaped metallic workpiece, with at least one circulating conveyor provided with processing elements, wherein the conveyor at least approximately linearly passes the processing elements obliquely or transversely to the feed direction of the workpiece in the region of the workpiece to be machined.

Die Erfindung betrifft außerdem ein Bearbeitungselement für eine Vorrichtung zum Bearbeiten eines band- oder plattenförmigen metallischen Werkstücks.The invention also relates to a machining element for a device for machining a band-shaped or plate-shaped metal workpiece.

Eine gattungsgemäße Vorrichtung ist aus der DE 103 20 295 A1 bekannt.A generic device is from the DE 103 20 295 A1 known.

Beim Laserschneiden von metallischen Werkstücken bildet sich an den Schnittkanten sowie an den Schnittflächen eine Oxidschicht bzw. eine Oxidhaut. Von Nachteil bei der Oxidschicht ist, dass eine darauf aufgetragene Lackierung oder Verzinkung relativ schnell wieder abspringt. Aus diesem Grund werden die metallischen Werkstücke vor dem Lackieren und Verzinken abgeschliffen.In the laser cutting of metallic workpieces, an oxide layer or an oxide skin is formed at the cut edges and at the cut surfaces. A disadvantage of the oxide layer is that a paint or zinc coating applied to it bounces off relatively quickly. For this reason, the metallic workpieces are ground off before painting and galvanizing.

Ferner ist es in der Regel notwendig, dass die Kanten, insbesondere die Schnittkanten entgratet bzw. verrundet werden. Des weiteren kann es vorteilhaft sein, die Oberflächen des band- oder plattenförmigen metallischen Werkstücks fein zu schleifen.Furthermore, it is generally necessary for the edges, in particular the cut edges, to be deburred or rounded. Furthermore, it may be advantageous to finely grind the surfaces of the strip or plate-shaped metal workpiece.

Ein besonders vorteilhaftes Verfahren zum Entfernen der Oxidschicht sowie zum Entgraten der (Schnitt-) Kanten sowie der Schnittflächen ist aus der DE 103 20 295 A1 bekannt. Dabei ist eine mit wenigstens einem Bearbeitungselement versehene umlaufende Fördereinrichtung vorgesehen, wobei die Fördereinrichtung das wenigstens eine Bearbeitungselement im Bereich des zu bearbeitenden Werkstücks wenigstens annähernd linear vorbeiführt.A particularly advantageous method for removing the oxide layer and for deburring the (cut) edges and the cut surfaces is from the DE 103 20 295 A1 known. In this case, a provided with at least one processing element circulating conveyor is provided, wherein the conveyor at least approximately linearly passes the at least one processing element in the region of the workpiece to be machined.

Da das Bearbeitungselement aufgrund der Anordnung an einer umlaufenden Fördereinrichtung nicht starr auf einer Position verharrt, sondern auf der ganzen Länge, die zur Durchführung des Werkstücks vorhanden ist, vorbeigeführt wird, ist eine gleichmäßige Abnutzung des wenigstens einen Bearbeitungselements gewährleistet. Das Werkstück kann dabei in einfacher Weise schräg, vorzugsweise quer zur Umlaufrichtung des Bearbeitungselements durchgeführt bzw. durchgezogen werden, so dass das Werkstück gleichmäßig von dem Bearbeitungselement bearbeitet wird.Since the processing element does not remain rigidly on a position due to the arrangement on a revolving conveyor, but is guided past the entire length which is present for the passage of the workpiece, uniform wear of the at least one processing element is ensured. The workpiece can be carried out in a simple manner obliquely, preferably transversely to the direction of rotation of the processing element or pulled through, so that the workpiece is processed evenly by the processing element.

Aufgrund des linearen Verlaufes des Bearbeitungselements im Bereich des zu bearbeitenden Werkstücks ist sichergestellt, dass das Bearbeitungselement in alle Aussparungen oder Löcher des Werkstückes eindringt und somit die Oxidschicht an allen Schnittflächen und Schnittkanten entfernt. Das schräg bzw. quer zur Vorschubrichtung des Werkstücks auf dem Werkstück entlanggezogene Bearbeitungselement dringt, ähnlich wie ein Pinsel, der auf einem Metallstück entlanggezogen wird, in jede Aussparung ein.Due to the linear course of the processing element in the region of the workpiece to be machined, it is ensured that the processing element penetrates into all recesses or holes of the workpiece and thus removes the oxide layer at all cut surfaces and cut edges. The obliquely or transversely to the feed direction of the workpiece on the workpiece along drawn workpiece penetrates, similar to a brush, which is pulled along on a piece of metal, in each recess.

In vorteilhafter Weise werden mit der gattungsgemäßen Vorrichtung sowohl die Oberflächen, d.h. die Hauptflächen des band- oder plattenförmigen metallischen Werkstücks bearbeitet, als auch die Schnittflächen und Schnittkanten entzundert. Die Vorrichtung entgratet außerdem die Kanten und Schnittflächen und kann zum Feinschleifen eingesetzt werden.Advantageously, both the surfaces, ie the main surfaces of the strip-shaped or plate-shaped metal workpiece are processed with the generic device, as well as the cut surfaces and cut edges descaled. The device also deburrs the edges and cut surfaces and can be used for fine grinding.

Zum weiteren Stand der Technik wird auf die DE 197 39 895 C2 verwiesen.For further prior art is on the DE 197 39 895 C2 directed.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die gattungsgemäße Vorrichtung weiterzuentwickeln, um insbesondere eine besonders kostengünstige und gleichmäßige Bearbeitung von band- oder plattenförmigen metallischen Werkstücken zu erreichen, wobei die Vorrichtung einfach zu montieren und zu warten sein soll.The present invention has for its object to further develop the generic device, in particular to achieve a particularly cost-effective and uniform machining of strip or plate-shaped metal workpieces, the device should be easy to assemble and maintain.

Der vorliegenden Aufgabe liegt auch die Aufgabe zugrunde, ein Bearbeitungselement für eine Vorrichtung zum Bearbeiten eines band- oder plattenförmigen metallischen Werkstücks zu schaffen, wobei das Bearbeitungselement ein gleichmäßiges und schnelles Bearbeiten der band- oder plattenförmigen metallischen Werkstücke ermöglichen und einfach zu wechseln sein soll.The present object is also an object of the invention to provide a processing element for a device for processing a band-shaped or plate-shaped metal workpiece, wherein the processing element allow a uniform and fast processing of the band- or plate-shaped metal workpieces and should be easy to change.

Erfindungsgemäß wird diese Aufgabe bezüglich der zu schaffenden Vorrichtung durch Anspruch 1 gelöst.According to the invention this object is achieved with respect to the device to be created by claim 1.

Bezüglich eines vorteilhaften Bearbeitungselementes wird diese Aufgabe durch Anspruch 7 gelöst.With regard to an advantageous processing element, this object is achieved by claim 7.

Aus den Ansprüchen 10 und 11 ergibt sich ein bevorzugter Keilriemen mit einer umlaufenden Reihe von Bearbeitungselementen gemäß Anspruch 7.From claims 10 and 11 results in a preferred V-belt with a circumferential row of processing elements according to claim 7.

Dadurch, dass die Bearbeitungselemente als Borsten ausgebildet sind, kann die Oxidschicht in besonders vorteilhafter Weise von den Schnittkanten und den Schnittflächen entfernt werden. Außerdem werden die Kanten in vorteilhafter Weise entgratet. Dadurch, dass die Bearbeitungselemente an einem Ende eine Nut und am anderen Ende eine Feder aufweisen, können diese verdrehsicher hintereinandergereiht auf dem Riemen angeordnet werden. Die Ausbildung mit Nut und Feder ermöglicht dabei eine zuverlässige und definierte Montage. Besonders vorteilhaft ist die Ausgestaltung der Bearbeitungselemente mit in Umlaufrichtung des Riemens betrachtet seitlichen Auskragungen, durch welche sich die Bearbeitungselemente auf einer größeren Fläche des Riemens abstützen. Gemäß dem bisherigen Stand der Technik mussten auf den Keilriemen seitliche Begrenzungen aufvulkanisiert werden, wodurch eine verdrehsichere Befestigung der Bearbeitungselemente erreicht werden soll. Dies ist aufgrund der Ausgestaltung der Bearbeitungselemente mit seitlichen Auskragungen sowie der Nut und der Feder nicht mehr notwendig.The fact that the processing elements are formed as bristles, the oxide layer in a particularly advantageous manner the cut edges and the cut surfaces are removed. In addition, the edges are deburred in an advantageous manner. Characterized in that the processing elements have a groove at one end and a spring at the other end, these can be arranged in a rotationally sequentially arranged on the belt. The training with tongue and groove allows a reliable and defined installation. Particularly advantageous is the design of the processing elements with viewed in the circumferential direction of the belt side projections, through which the machining elements are supported on a larger surface of the belt. According to the prior art, lateral limitations had to be vulcanized onto the V-belt, as a result of which a twist-proof fastening of the processing elements is to be achieved. This is no longer necessary due to the design of the processing elements with lateral projections and the groove and the spring.

In Versuchen hat es sich als besonders geeignet herausgestellt, wenn der Riemen als dreifacher Keilriemen ausgebildet ist. Die Auskragungen der Bearbeitungselemente ermöglichen dabei eine Abstützung auf allen drei Riemen. Die auftretenden Kräfte werden somit gleichmäßig verteilt und die Belastungen entsprechend gering gehalten.In experiments, it has been found to be particularly suitable when the belt is designed as a triple V-belt. The protrusions of the processing elements allow it to be supported on all three belts. The forces are thus distributed evenly and kept the loads correspondingly low.

Besonders vorteilhaft ist es, wenn die Bearbeitungselemente mit dem Riemen verschraubt sind. Dies ermöglicht eine einfache und sichere Montage. Darüber hinaus können die Bearbeitungselemente, nachdem die Borsten entsprechend abgenützt sind, problemlos ausgetauscht werden. Vorteilhaft ist es dabei, wenn der Keilriemen eine Bohrung aufweist und die Bearbeitungselemente an ihrer Unterseite eine Öffnung aufweisen.It is particularly advantageous if the processing elements are screwed to the belt. This allows for easy and safe installation. In addition, the processing elements, after the bristles are worn out, easily replaced. It is advantageous if the V-belt has a bore and the processing elements have an opening on their underside.

Eine Ausgestaltung der Bearbeitungselemente aus Kunststoff, in die die Borsten eingeschossen sind, hat sich als besonders geeignet herausgestellt.An embodiment of the processing elements made of plastic, in which the bristles are injected, has proven to be particularly suitable.

Ein vorteilhaftes Bearbeitungselement mit einer Mehrzahl von Borsten für eine Vorrichtung zum Bearbeiten eines band- oder plattenförmigen metallischen Werkstücks ergibt sich aus Anspruch 7.An advantageous processing element with a plurality of bristles for a device for processing a strip-shaped or plate-shaped metal workpiece results from claim 7.

Aus Anspruch 10 ergibt sich ein Keilriemen mit einer umlaufenden Reihe von Bearbeitungselementen gemäß Anspruch 7. Erfindungsgemäß kann dabei vorgesehen sein, dass wenigstens ein Bearbeitungselement eine verlängerte Feder bzw. Nase aufweist und somit als Ausgleichsklotz dienen kann, um Riementoleranzen auszugleichen. In Versuchen hat sich dabei herausgestellt, dass eine Verlängerung der Feder bzw. des nasenförmigen Vorsprungs, der in die Nut eines angrenzenden Bearbeitungselements eindringt, um 1 bis 5 mm ausreichend ist. Die Feder des Bearbeitungselementes, welches als Ausgleichsklotz dient, kann dabei entsprechend gekürzt werden.From claim 10 results in a V-belt with a circumferential row of processing elements according to claim 7. According to the invention can be provided that at least one processing element has an elongated spring or nose and thus can serve as a compensation block to compensate for belt tolerances. In experiments, it has been found that an extension of the spring or the nose-shaped projection, which penetrates into the groove of an adjacent processing element, by 1 to 5 mm is sufficient. The spring of the processing element, which serves as a compensation block, can be shortened accordingly.

Erfindungsgemäß kann ferner vorgesehen sein, dass der Keilriemen mit einer umlaufenden Reihe von bündig hintereinander angeordneten Bearbeitungselementen versehen ist, so dass der Riemen mit einer gleichmäßigen Oberfläche von Borsten versehen ist.According to the invention, it can further be provided that the V-belt is provided with a circumferential row of processing elements arranged flush behind one another, so that the belt is provided with a uniform surface of bristles.

Fig. 2 zeigt einen derartigen Riemen 8 in einer Ausführungsform als Keilriemen. Der Keilriemen ist dabei als dreifacher Keilriemen 8 ausgebildet. Auf dem Keilriemen 8 ist eine Mehrzahl von Bearbeitungselementen 3 hintereinandergereiht angeordnet, wobei in Fig. 2 aus Übersichtlichkeitsgründen nur ein Teil der Bearbeitungselemente 3 dargestellt ist. Prinzipiell ist vorgesehen, dass die Bearbeitungselemente 3 hintereinandergereiht vollständig um den Riemen 8 umlaufen, also eine geschlossene Kette bilden. Die Bearbeitungselemente 3 sind mit Borsten 9 versehen. Die Borsten 9 sind dabei in bekannter Weise aus Metall gebildet. In einer einfachen Darstellung können die Borsten 9 gerade verlaufend ausgebildet sein. Vorteilhaft ist jedoch die Ausbildung der Borsten 9 mit einem gewellten oder gedrehten Verlauf, so dass die Borsten 9 einem struppigen Pinsel bzw. einem Büschel ähneln. Fig. 2 shows such a belt 8 in one embodiment as a V-belt. The V-belt is designed as a triple V-belt 8. On the V-belt 8, a plurality of processing elements 3 arranged in series, wherein in Fig. 2 for reasons of clarity, only a part of the processing elements 3 is shown. In principle, it is provided that the processing elements 3 in a row completely rotate around the belt 8, thus forming a closed chain. The processing elements 3 are provided with bristles 9. The bristles 9 are formed in a known manner from metal. In a simple illustration, the bristles 9 can be straight be educated. However, it is advantageous to form the bristles 9 with a corrugated or twisted course, so that the bristles 9 resemble a scrubby brush or a tuft.

Die Borsten 9 können in Bündeln in die Bearbeitungselemente 3 eingeschossen werden. Die Bearbeitungselemente 3 können dabei beispielsweise aus Kunststoff ausgebildet und entsprechende Aufnahmebohrungen aufweisen.The bristles 9 can be shot in bundles in the processing elements 3. The processing elements 3 can be made of plastic, for example, and have corresponding receiving bores.

Zum vorteilhaften Befestigen der Borsten 9 können die Borsten 9 mit nicht näher dargestellten Widerhaken versehen sein.For advantageous fastening of the bristles 9, the bristles 9 may be provided with not shown barbs.

Die Borsten 9 können bis zu 45°, vorzugsweise um 15°, in Umlaufrichtung des Keilriemens 8 geneigt sein. D.h. die Spitzen der Borsten 9 befinden sich in Umlaufrichtung vor dem entsprechend abgewandten Ende der Borsten 9, welches mit dem Bearbeitungselemente 3 verbunden ist. Wie sich in Versuchen herausgestellt hat, dringen die um 15° schräg gestellten Borsten 9 besonders vorteilhaft in Aussparungen des Werkstücks 1 ein, woraus ein besonders vorteilhaftes Entfernen der Oxidschicht von Schnittflächen und Schnittkanten des Werkstücks 1 resultiert und eine Verrundung der Kanten möglich ist.The bristles 9 may be inclined up to 45 °, preferably by 15 °, in the direction of rotation of the belt 8. That the tips of the bristles 9 are in the direction of rotation in front of the correspondingly opposite end of the bristles 9, which is connected to the processing elements 3. As has been found in experiments, penetrate the inclined by 15 ° bristles 9 penetrate particularly advantageous in recesses of the workpiece 1, resulting in a particularly advantageous removal of the oxide layer of cut surfaces and cut edges of the workpiece 1 results and a rounding of the edges is possible.

In nicht dargestellter Weise können die Bearbeitungselemente 3 auch Stützborsten aufweisen, welche die schräggestellten Borsten 9 stabilisieren und somit deren Eindringverhalten in Aussparungen des Werkstücks 1 verbessern sollen. Die Stützborsten können dabei kürzer ausgebildet sein und eine entsprechend hohe Biegekraft aufweisen. Eine senkrechte bzw. rechtwinklige Anordnung der Stützborsten zu der Oberfläche der Bearbeitungselemente 3 hat sich als vorteilhaft herausgestellt.In a manner not shown, the processing elements 3 may also have support bristles which stabilize the slanted bristles 9 and thus improve their penetration into recesses of the workpiece 1. The support bristles can be made shorter and have a correspondingly high bending force. A vertical or rectangular arrangement of the support bristles to the surface of the processing elements 3 has been found to be advantageous.

Die Borsten 9 können in vorteilhafter Weise als geseilte Borsten ausgebildet sein.The bristles 9 may be advantageously formed as roped bristles.

In einer alternativen, ebenfalls nicht dargestellten Ausgestaltung kann auch vorgesehen sein, dass die Borsten 9 von einer Ummantelung stabilisierend bzw. stützend umfasst sind. Die Ummantelung kann dabei als Alternative zu den Stützborsten dienen. Die Ummantelung kann sich vorzugsweise vom unteren Ende der Borsten 9 bis in etwa zur Mitte der Borsten 9 erstrecken.In an alternative embodiment, also not shown, it can also be provided that the bristles 9 are covered by a jacket in a stabilizing or supporting manner. The sheath can serve as an alternative to the support bristles. The sheath may preferably extend from the lower end of the bristles 9 to approximately the middle of the bristles 9.

Gemäß den Figuren 2, 3 und 4 ist aus Übersichtlichkeitsgründen lediglich ein Bearbeitungselement 3 mit Borsten 9 dargestellt. Grundsätzlich ist vorgesehen, dass jedes Bearbeitungselement 3 Borsten 9 trägt.According to the FIGS. 2, 3 and 4 For reasons of clarity, only one processing element 3 with bristles 9 is shown. In principle, it is provided that each processing element 3 carries bristles 9.

Die Bearbeitungselemente 3 weisen an einem Ende eine Nut 10 und am anderen Ende eine Feder 11 auf, mittels derer die Bearbeitungselemente 3 miteinander verbindbar sind. Ein Verdrehen der Bearbeitungselemente 3 wird durch die Nut-Feder-Verbindung in einfacher und vorteilhafter Weise verhindert.The processing elements 3 have at one end a groove 10 and at the other end a spring 11, by means of which the processing elements 3 are connectable to each other. A rotation of the processing elements 3 is prevented by the tongue and groove connection in a simple and advantageous manner.

Wie sich des weiteren aus den Figuren 2, 3 und 4 ergibt, weisen die Bearbeitungselemente 3 in Umlaufrichtung betrachtet seitliche Auskragungen 12 auf. Die Auskragungen 12 ermöglichen dabei, dass sich die Bearbeitungselemente 3 auf einer größeren Fläche des Keilriemens 8 abstützen. In einer Ausgestaltung des Keilriemens 8 als dreifacher Keilriemen wird dadurch erreicht, dass sich die Bearbeitungselemente 3 auf allen drei Riemen abstützen. Im Ausführungsbeispiel ist vorgesehen, dass die Bearbeitungselemente 3 an jeder Seite zwei Auskragungen 12 aufweisen. Die Auskragungen 12 sind vorzugsweise einstückig mit dem Bearbeitungselement 3 ausgebildet. Die Bearbeitungselemente 3 sind im Ausführungsbeispiel mittels einer Befestigungsschraube 13 mit dem Keilriemen 8 verschraubt. Hierfür sind in dem Keilriemen 8 Bohrungen 14 eingebracht bzw. einbringbar. Die Bearbeitungselemente 3 weisen an ihrer dem Keilriemen 8 zugewandten Unterseite eine nicht näher dargestellte Öffnung auf, die zum Verschrauben mit den Befestigungsschrauben 13 dient.As further from the FIGS. 2, 3 and 4 results, the processing elements 3 viewed in the circumferential direction lateral projections 12. The projections 12 make it possible for the processing elements 3 to be supported on a larger surface of the V-belt 8. In one embodiment of the V-belt 8 as a triple V-belt is achieved by supporting the processing elements 3 on all three belts. In the exemplary embodiment, it is provided that the processing elements 3 have two projections 12 on each side. The projections 12 are preferably formed integrally with the processing element 3.

The processing elements 3 have at their the V-belt 8 facing the underside an opening, not shown, which serves for screwing with the fastening screws 13.

Wie sich aus den Figuren 2, 3 und 4 ergibt, ist im Ausführungsbeispiel vorgesehen, dass ein Bearbeitungselement 3 eine verlängerte Feder 11a aufweist. Die Feder 11a bzw. die Nase dieses Bearbeitungselemente 3 dient zum Ausgleich eventueller Riementoleranzen und kann entsprechend gekürzt bzw. abgenommen werden. In Versuchen hat sich herausgestellt, dass eine Verlängerung der Feder 11a um 1 bis 3 mm ausreichend ist, um als Toleranzausgleich zu dienen. In Versuchen hat sich des weiteren herausgestellt, dass ein Bearbeitungselement 3 mit einer verlängerten Feder 11a pro Keilriemen 8 ausreichend ist.As is clear from the FIGS. 2, 3 and 4 results, it is provided in the embodiment that a processing element 3 has an elongated spring 11a. The spring 11a or the nose of this processing elements 3 serves to compensate for possible belt tolerances and can be correspondingly reduced or removed. In experiments it has been found that an extension of the spring 11a by 1 to 3 mm is sufficient to serve as tolerance compensation. In experiments it has further been found that a processing element 3 with an extended spring 11a per V-belt 8 is sufficient.

Eine Umlaufgeschwindigkeit der Bearbeitungselemente 3 mit den Borsten 9 von vorzugsweise 14 bis 16 m/s, ist besonders vorteilhaft. Diese Geschwindigkeit gewährleistet zum einen eine schnelle Bearbeitung der Werkstücke 1 und hat sich zum anderen hinsichtlich der Zuverlässigkeit der Bearbeitung und der Belastung der beteiligten Bauteile als geeignet herausgestellt.A rotational speed of the processing elements 3 with the bristles 9 of preferably 14 to 16 m / s, is particularly advantageous. This speed ensures, on the one hand, a rapid processing of the workpieces 1 and, on the other hand, has proved to be suitable with regard to the reliability of the machining and the loading of the components involved.
