Description
Die vorliegende Erfindung betrifft eine Vorrichtung zum Rollbördeln sowie ein Verfahren zum Rollbördeln gemäß den Merkmalen der Patentansprüche 1 bzw. 2.The The present invention relates to a device for roll flanging and a method for roll flanging according to the characteristics of the claims 1 or 2.
Unter dem Begriff "Bördeln" versteht man das Umbiegen der Kante eines Blechteils. Bördeln dient einerseits der Versteifung des Blechteilrandes sowie der Entschärfung des Blechteilrandes. Durch Bördeln können auch zwei Blechteile miteinander verbunden werden, indem eine Kante eines ersten Blechteils zwischen ein anderes Blechteil und dessen umgebördelten Rand eingeklemmt wird. So weisen Türen und Klappen von Automobilen üblicherweise ein Außenhautblech auf, dessen Rand um ein Trägerblech herum gebördelt ist. Bei Großserienteilen erfolgt das Bördeln vollautomatisiert. Das Bördeln kann durch Bördelpressen erfolgen, wobei das zu bördelnde Blech zwischen ein Werkzeugoberteil und ein Werkzeugunterteil eingebracht wird. In einem ersten Arbeitsschritt wird der zu bördelnde Rand durch die Presswerkzeuge vorgebogen und anschließend durch "Schieber" o.ä. fertiggebördelt bzw. umgebogen. Bördelpressen sind sehr teuer und daher nur für sehr große Stückzahlen rentabel einsetzbar.Under The term "flanging" is understood to mean Bending the edge of a sheet metal part. Beading serves on the one hand the Stiffening of the sheet metal edge and the defusing of the sheet metal edge. By crimping can Also, two sheet metal parts are joined together by an edge a first sheet metal part between another sheet metal part and its beaded Edge is pinched. Such doors and flaps of automobiles usually have an outer skin sheet on, the edge of a support plate beaded around is. For high volume parts the beading takes place fully automated. The beading can by crimping presses take place, with the to be flanged Sheet metal inserted between a tool shell and a tool base becomes. In a first step, the to be flanged Edge pre-bent by the pressing tools and then by "slide" or similar. finished beaded or bent. Bördelpressen are very expensive and therefore only for very size numbers profitable use.
Ein
weiteres, ebenfalls seit langem bekanntes Bördelverfahren ist das "Rollbördeln", das z.B. in der
Aufgabe der Erfindung ist es, eine Vorrichtung und ein Verfahren zum Rollbördeln zu schaffen, mit der bzw. mit dem kürzere Taktzeiten möglich sind.task It is the object of the invention to provide an apparatus and method for roll flanging create, with or with the shorter one Cycle times possible are.
Diese Aufgabe wird durch die Merkmale der Patentansprüche 1 bzw. 2 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.These The object is solved by the features of claims 1 and 2, respectively. advantageous Refinements and developments of the invention are the dependent claims remove.
Die Erfindung geht von einer Vorrichtung zum Rollbördeln eines Randes eines Blechteils aus. Bei dem Blechteil kann es sich beispielsweise um ein Karosserieteil eines Fahrzeugs handeln. Das Blechteil wird während des Bördelns in eine Halteeinrichtung eingebracht bzw. eingespannt. Die Halteeinrichtung kann auch als „Bördelbett" bezeichnet werden. Ferner ist eine Rolleinrichtung vorgesehen, die relativ zu der zu bördelnden Kante des Blechteils verfahrbar ist. Die Rolleinrichtung weist eine erste Rolle auf, die beim Verfahren der Rolleinrichtung relativ zu dem Blechteil auf dem Rand des Blechteils abrollt. Die Rolle übt dabei eine Biegekraft bzw. eine "Bördelkraft" auf den Rand des Blechteils aus. Dadurch wird der Rand des Blechteils beim Verfahren der Rolleinrichtung um einen vorgegebenen Bördelwinkel umgebogen bzw. gebördelt.The The invention relates to a device for roll flanging an edge of a sheet metal part out. The sheet metal part may be, for example, a body part act of a vehicle. The sheet metal part is during the beading in a holding device introduced or clamped. The holding device can also be referred to as a "crimping bed" a rolling device is provided which is to be crimped relative to the Edge of the sheet metal part is movable. The rolling device has a first role in the process of rolling device relative rolls to the sheet metal part on the edge of the sheet metal part. The role is practiced a bending force or a "flanging force" on the edge of the Sheet metal part. This will cause the edge of the sheet metal part in the process the rolling device bent or crimped to a predetermined flanging angle.
Der Kern der Erfindung besteht darin, dass die Rolleinrichtung eine zweite Rolle aufweist, die in einem Abstand zu der ersten Rolle angeordnet ist. Die zweite Rolle wird beim Verfahren der Rolleinrichtung mit der ersten Rolle mitbewegt. Sie rollt ebenfalls auf dem Rand des Blechteils ab. Während die erste Rolle den Rand des Blechteils vorbiegt bzw. vorbördelt, biegt die zweite Rolle bzw. bördelt die zweite Rolle den Rand weiter um. In Bewegungsrichtung gesehen ist die zweite Rolle also "hinter" der ersten Rolle angeordnet. Die erste Rolle übernimmt somit die Vorbearbeitung bzw. Vorbördelung und die zweite Rolle die Nachbearbeitung bzw. Nachbördelung.Of the Core of the invention is that the rolling device a second roller, which is at a distance to the first roller is arranged. The second role is played by moving the rolling device moved with the first role. She also rolls on the edge of the sheet metal part. While the first roll prebends or prebends the edge of the sheet metal part, bends the second roll or beads the second roll continues around the edge. Seen in the direction of movement So the second role is "behind" the first role arranged. The first role thus takes over the pre-processing or Vorbördelung and the second roll the post-processing or flanging.
Vorzugsweise sind die beiden Rollen an einem gemeinsamen Rollenträger gelagert. Die beiden Rollen sind so an dem Rollenträger angeordnet, dass eine Drehachse der zweiten Rolle einen vorgegebenen Winkel mit einer Drehachse der ersten Rolle einschließt. Der Winkel, den die beiden Rollenachsen miteinander einschließen, kann beispielsweise zwischen 0 und 90°, zwischen 0° und 60°, zwischen 0° und 30° oder zwischen 0° und 15° liegen. Bei einem konkreten Ausführungsbeispiel beträgt der Winkel zwischen den beiden Drehachsen der Rollen beispielsweise genau 30°.Preferably the two rollers are mounted on a common roller carrier. The two rollers are arranged on the roller carrier, that an axis of rotation the second roller a predetermined angle with a rotation axis the first roll. The angle that the two roller axes enclose with each other can for example between 0 and 90 °, between 0 ° and 60 °, between 0 ° and 30 ° or between 0 ° and 15 °. In a concrete embodiment is the angle between the two axes of rotation of the rollers, for example exactly 30 °.
Nach einer Weiterbildung der Erfindung ist der Rollenträger am freien Ende eines Roboterarms angeordnet. Der Rollenträger und die beide Rollen werden also während der Bearbeitung von dem Roboterarm geführt. Während eines Arbeitsschritts wird der Rand des Blechteils somit durch die vordere bzw. erste Rolle vorgebördelt und durch die zweite bzw. hintere Rolle nach oder fertig gebördelt. Im Unterschied zum Stand der Technik muss der Roboterarm also nicht mehrmals hintereinander den gleichen Fahrweg durch laufen. Dadurch wird erheblich Zeit eingespart, was eine Taktzeitverkürzung ermöglicht.According to a development of the invention, the roller carrier is arranged at the free end of a robot arm. The roller carrier and the two rollers are thus guided during the processing of the robot arm. During a working step, the edge of the sheet metal part is thus vorgebördelt by the front or first role and crimped or finished by the second or rear role. In contrast to the prior art, therefore, the robot arm does not have to travel through the same track several times in succession. This will take time saved, which allows a Taktzeitverkürzung.
Es sei ausdrücklich darauf hingewiesen, dass die Erfindung nicht auf eine Bördeleinrichtung mit zwei Bördelrollen beschränkt ist. Prinzipiell ist auch denkbar, dass an dem Rollenträger hintereinander drei oder vier oder mehr Bördelrollen angeordnet sind, die den Rand des zu bearbeitenden Werkstücks jeweils ein Stück weit weiter bördeln. Wesentlich ist, dass während eines einzigen Arbeitsschritts gleichzeitig mindestens zwei hintereinander angeordnete Bördelrollen verfahren werden.It be explicit It should be noted that the invention is not limited to a crimping device two crimping rollers limited is. In principle, it is also conceivable that one behind the other at the roller carrier three or four or more crimping rollers are arranged, respectively, the edge of the workpiece to be machined one piece far further flanging. It is essential that while a single work step simultaneously at least two consecutively arranged crimping rollers be moved.
