Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Umlegen einer Bördelkante eines Werkstücks durch Rollfalzen nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for folding a flanged edge Workpiece by roller folds according to the preamble of claim 1.
Eine bekannte Vorrichtung zum Umlegen einer Bördelkante durch Rollfalzen (EP 0 577 876 B1) umfasst eine Werkzeugeinheit, die mittels eines Gelenkarmroboters gesteuert bewegbar ist. An der Werkzeugeinheit ist drehbar eine Falzrolle gelagert, die unter Druckaufbringung und mit bestimmter Winkelstellung entlang und in Anlage an der Bördelkante zu deren Umlegung rollbar ist.A known device for folding a flanged edge by roller folds (EP 0 577 876 B1) comprises a tool unit which is operated by means of an articulated arm robot is controlled movable. A is rotatable on the tool unit Folded roller stored under pressure and with a certain angular position can be rolled along and in contact with the flanged edge for its folding.
Das Werkstück mit der vor dem Falzvorgang bereits um etwa 90° abgekanteten Bördelkante wird in eine Halteeinrichtung zur Halterung des Werkstücks und zur Unterstützung des Bereichs der Bördelkante eingelegt. Zudem ist hier die Herstellung einer Fügeverbindung zwischen zwei Blechbauteilen gezeigt, wobei mit dem Falzvorgang die Bördelkante eines äußeren Blechbauteils um einen Rand eines zweiten Blechbauteils gebördelt wird.The workpiece with the one already bent by about 90 ° before the folding process Flanged edge is in a holding device for holding the workpiece and inserted to support the area of the flanged edge. In addition, here is the production of a joint connection between two sheet metal components is shown, with the folding process around the flanged edge of an outer sheet metal component an edge of a second sheet metal component is crimped.
Der Falzvorgang erfolgt hier zweistufig, indem die zylindrische Falzrolle unter Druck mit einem Anstellwinkel dergestalt an der Bördelkante entlang geführt wird, dass diese in einer Vorfalzung um etwa 45° umgelegt wird. Anschließend wird für eine zweite Falzstufe die zylindrische Falzrolle mit ihrer Rollenachse geschwenkt dergestalt, dass für eine Endfalzung die Bördelkante vollständig um 90° umgelegt wird.The folding process takes place here in two stages, with the cylindrical folding roller underneath Print with an angle of attack such along the flanged edge is that this is folded in about 45 ° in a pre-fold. Subsequently the cylindrical folding roller with its roller axis is used for a second folding stage pivoted in such a way that the flanged edge is completely folded for final folding is turned by 90 °.
Für eine lagegenaue Führung der Falzrolle in der ersten Falzstufe als Vorfalzung wird eine mit der Falzrolle verbundene Stützrolle an einer Führungsbahn der Halteeinrichtung entlang geführt. Die von einem Gelenkarmroboter durchzuführende Führung ist dabei relativ einfach und genau zu erreichen. Die erforderliche anschließende Kippung der Falzrollenachse in Verbindung mit einem zweiten Abfahrvorgang entlang der Bördelkante erfordert dagegen aufwendige Maßnahmen. Insbesondere hebt durch diese erforderliche Kippung die Stützrolle von der Führungsbahn ab, so dass für die Endfalzvorgang eine genaue Stützrollenführung der Falzrolle nicht mehr zur Verfügung steht, was zu ungleichmäßigen und damit unbefriedigenden Falzungen führen kann.For precise guidance of the folding roller in the first folding stage as pre-folding becomes a support roller connected to the folding roller on a guideway guided along the holding device. The one to be performed by an articulated arm robot Leadership is relatively easy and precise to achieve. The required subsequent tilting of the folding roller axis in connection with a second shutdown along the flanged edge, however, requires complex Activities. In particular, this required tilting lifts the support roller from the guideway, so that for the final folding process exact support roller guide of the folding roller is no longer available, what can lead to uneven and therefore unsatisfactory folds.
Aufgabe der Erfindung ist es, eine gattungsgemäße Vorrichtung zum Umlegen einer Bördelkante eines Werkstücks durch Rollfalzen so weiterzubilden, dass mit weniger Aufwand ein gutes Falzergebnis erzielbar ist.The object of the invention is a generic device for folding a flanged edge of a workpiece by roller folds so that a good folding result can be achieved with less effort.
Diese Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved with the features of claim 1.
Gemäß Anspruch 1 ist die Werkzeugeinheit am Antrieb um eine Schwenkachse schwenkbar gelagert und um einen bestimmten Schwenkwinkel in wenigstens zwei Arbeitspositionen schwenkbar. Den wenigstens zwei Arbeitspositionen ist jeweils eine an der Werkzeugeinheit drehbar gelagerte Falzrolle zugeordnet, wobei die wenigstens zwei, den Arbeitspositionen zugeordneten Falzrollen unterschiedlich ausgebildete und bezüglich der Bördelkantenumlegung unterschiedlich wirksame Falzrollenumfangsflächen aufweisen.According to claim 1, the tool unit on the drive is about a pivot axis pivoted and at least by a certain pivot angle two working positions swiveling. The at least two working positions is a folding roller rotatably mounted on the tool unit assigned, the at least two assigned to the working positions Folding rolls differently designed and with regard to the flanging edge folding have differently effective folding roller peripheral surfaces.
Für eine wenigstens zweistufige Umlegung der Bördelkante wird für eine Vorfalzung die Werkzeugkante mit der ersten Falzrolle in deren Funktionsstellung an der Bördelkante entlang geführt. Für die anschließende Endfalzung wird dann die Werkzeugeinheit in die zweite Arbeitsposition geschwenkt und mit der zweiten Falzrolle in deren Funktionsstellung an der Bördelkante entlang geführt.For an at least two-stage folding of the flanged edge is for a pre-fold the tool edge with the first folding roller in its functional position led along the flanged edge. For the subsequent final fold then pivoted the tool unit into the second working position and with the second folding roller in its functional position along the flanged edge guided.
Die verwendeten Falzrollen haben unterschiedliche, für den jeweiligen Vorgang wirksame Falzrollenumfangsflächen, mit denen insbesondere Vorfalzungen und die Endfalzung durchgeführt werden können. Die dazu erforderlichen unterschiedlichen Anstellwinkel der Falzrollenumfangsflächen bezüglich der Bördelkante werden somit erfindungsgemäß durch die unterschiedlich ausgebildeten Falzrollen zur Verfügung gestellt, die lediglich in ihre gerade erforderliche Funktionsstellung geschwenkt werden müssen. Damit kann mittels eines Robotergelenkarms die Werkzeugeinheit in allen Falzstufen über die gleiche Bewegungsbahn geführt werden, im Gegensatz zum Stand der Technik, wo komplizierte Änderungen der Bewegungsbahn des Robotergelenkarms in den einzelnen Falzstufen durch die Verkippungen der Falzrolle zu berücksichtigen sind.The folding rollers used have different ones for the respective process effective folding roller peripheral surfaces, with which in particular pre-folds and the final folding can be done. The necessary different angles of attack of the folding roller peripheral surfaces with respect to the According to the invention, the crimped edges are thus formed by the differently designed ones Folding rolls are provided that are only in their just required Functional position must be pivoted. So that by means of a Robot articulated arm the tool unit in all folding stages over the same Movement path are performed, in contrast to the prior art, where complicated changes in the path of movement of the robot articulated arm in the individual folding levels due to the tilting of the folding roller are.
Eine besonders einfache geometrische Anordnung ergibt sich gemäß Anspruch 2, indem die Rollendrehachsen der wenigstens zwei Falzrollen radial zur Schwenkachse in einer senkrechten Ebene zur Schwenkachse ausgerichtet liegen und den Schwenkwinkel einschließen. Die Schwenkachse wird für einen Falzvorgang zweckmäßig etwa parallel zur aufgekanteten Bördelkante und etwa senkrecht zur an die Bördelkante angrenzenden Werkstückfläche eingestellt. Das Anfahren der unterschiedlichen Arbeitspositionen kann durch Hin- und Herschwenken der Werkzeugeinheit um die Schwenkachse erfolgen. Die Arbeitspositionen können jedoch auch durch ein Weiterdrehen in einer Richtung angefahren werden, wobei dann die Schwenkachse als Drehachse ausgebildet ist. Um die unterschiedlichen Falzrollen durch einfache Schwenkbewegungen jeweils in ihre Funktionsstellung zu bringen, ist es erforderlich, die zur Umlegung der Bördelkante wirksamen Falzrollenumfangsflächen etwa im gleichen Abstand zur Schwenkachse anzuordnen. A particularly simple geometric arrangement results according to the claim 2, by the roller axes of rotation of the at least two folding rollers radially aligned to the swivel axis in a plane perpendicular to the swivel axis lie and include the swivel angle. The swivel axis is for a folding process expedient approximately parallel to the folded edge and approximately perpendicular to the workpiece surface adjacent to the flanged edge set. The different working positions can be approached by Swiveling the tool unit back and forth about the swivel axis. The working positions can, however, also be continued by turning in one Direction are approached, with the pivot axis as the axis of rotation is trained. To the different folding rollers by simple swivel movements to bring them into their functional position, it is necessary the folding roller circumferential surfaces effective for folding the flanged edge approximately to be arranged at the same distance from the swivel axis.
Grundsätzlich können die Falzrollenumfangsflächen der einzelnen Falzrollen jeweils entsprechend den vorliegenden Erfordernissen und Gegebenheiten hinsichtlich einer Vorfalzung und Endfalzung für bestimmte gewünschte Falzausbildungen ausgeführt sein. Für einfache gerade Falze sind gemäß Anspruch 3 die unterschiedlichen Falzrollenumfangsflächen in einfacher Weise als Kegelflächen mit unterschiedlichen Kegelwinkeln und/oder insbesondere für die Endfalzung als Zylinderflächen auszuführen, wodurch mit jeder der einzelnen Falzrollen unterschiedliche Anstellwinkel bezüglich der Bördelkante für eine zugeordnete stufenweise Rollfalzung erreichbar sind.Basically, the folding roller peripheral surfaces of the individual folding rollers each in accordance with the existing requirements and conditions with regard to a pre-fold and final fold for certain desired fold configurations be executed. For simple straight folds are according to claim 3 the different folding roller peripheral surfaces in a simple manner as conical surfaces with different cone angles and / or in particular for the final fold as cylindrical surfaces, which means that each of the individual Folding rollers have different angles of attack with respect to the flanged edge for an assigned gradual roll fold can be reached.
In einer besonders, bevorzugten konkreten Ausführungsform nach Anspruch 4 sind drei Falzrollen in einem Schwenkwinkelabstand von jeweils 120° vorgesehen. Eine erste Falzrolle ist dabei als Kegelrolle mit einer Kegelfläche für eine Umlegung der Bördelkante in einer ersten Vorfalzstufe um etwa 30° ausgelegt. Eine zweite Falzrolle ist entsprechend als Kegelrolle für eine zweite Vorfalzstufe mit einer Umlegung der Bördelkante um etwa 60° ausgelegt. Für die Endfalzung ist die dritte Falzrolle als Zylinderrolle ausgebildet.In a particularly preferred specific embodiment according to claim 4 three folding rollers are provided at a swivel angle distance of 120 ° each. A first folding roller is a tapered roller with a tapered surface for one The flanged edge is folded over in a first pre-folding stage by approximately 30 °. A second folding roller is accordingly a tapered roller for a second pre-folding stage designed with a fold of the flanged edge by about 60 °. For the Final fold, the third folding roller is designed as a cylindrical roller.
Eine besonders vorteilhafte Weiterbildung wird mit den Merkmalen des Anspruchs
5 erreicht, indem koaxial zu den Falzrollen Stützrollen angebracht
sind, die sich auf einer vorgegebenen Führungsbahn an der Werkstück- Halteeinrichtung
abstützen und dort abrollen. Da für jede Falzstufe die selbe Bewegungsbahn
abgefahren wird und die unterschiedlichen Anstellwinkel bezüglich
der umzulegenden Bördelkante durch die Form der einzelnen Falzrollen vorgegeben
werden, kann in jeder Falzstufe die jeweilige Stützrolle an der selben
Führungsbahn abrollen, wodurch in jeder Falzstufe eine gute Führung vorgegeben
ist und ein insgesamt gutes Falzergebnis erzielt wird.A particularly advantageous further development comes with the features of the
Die Stützrollen werden in einer einfachen Ausführungsform nach Anspruch 6 drehfest, vorzugsweise integral und materialeinheitlich mit den Falzrollen verbunden und zur Schwenkachse hinweisend angeordnet, so dass sie an einer Führungsbahn neben der Bördelkante abrollen können.The support rollers are in a simple embodiment according to claim 6 non-rotatably, preferably integrally and uniformly connected to the folding rollers and arranged pointing to the pivot axis, so that they on a Roll the guideway next to the flanged edge.
Die Werkzeugeinheit ist nach Anspruch 7 als ein eigenständiges Bauteil aufbaubar
und endseitig an einen Robotergelenkarm anflanschbar. Durch unterschiedliche
Flanschausbildungen kann die selbe Werkzeugeinheit ggf. mit unterschiedlichen
Robotergelenkarmen kombiniert werden.The tool unit can be constructed as an independent component according to
Die erfindungsgemäße Vorrichtung kann sowohl für eine einfache Bördelrandausbildung als auch gemäß Anspruch 8 für eine Fügeverbindung von zwei Blechteilen verwendet werden.The device according to the invention can be used both for simple flanging formation as well as according to claim 8 for a joint connection of two Sheet metal parts are used.
