Description

Verfahren zum Falzen eines Randes eines Blechbauteils , insbesondere eines Blechbauteils einer Kfz . -KarosserieA method for folding an edge of a sheet metal component, in particular a sheet metal part of a motor vehicle. -Body
Die Erfindung betrifft ein Verfahren zum Falzen eines Randes eines Blechbauteils, insbesondere einer Tur, einer Klappe oder eines ahnlichen Bauteils einer Kfz.- Karosserie, bei dem der abgewinkelte Rand mit einer längs dieses Randes geführten Falzrolle auf dem angrenzenden Teil des Blechbauteils zur Anlage gebracht wird, wobei als Falzrolle eine an ihrer umlaufenden Peripherie (Mantelflache) konisch konturierte Rolle mit einer schiefen Anstellung ihrer Rotationsachse zur Ebene des Blechbauteils verwendet wird, dass sie in Bewegungsrichtung mit ihrem vorne liegenden Bereich ihres größeren Durchmessers die Kante des abgewinkelten Randes zuerst angreift und dann kontinuierlich über den konischen Bereich ihres Mantels bis zum Bereich ihres kleinsten Durchmessers den Rand weiter bis zur Anlage auf dem angrenzenden Teil des Blechbauteils umfaltet.The invention relates to a method for folding an edge of a sheet metal component, in particular a door, a flap or similar component of a Kf.-.- bodywork, wherein the angled edge is brought to a guided along this edge folding roller on the adjacent part of the sheet metal component to the plant , wherein as a folding roller at its peripheral periphery (lateral surface) conically contoured roll is used with an oblique position of its axis of rotation to the sheet metal component level that it first attacks the edge of the angled edge in the direction of movement with its forward portion of its larger diameter and then continuously over the conical region of its shell to the region of its smallest diameter, the edge further folded up to the plant on the adjacent part of the sheet metal component.
Bei in der Praxis üblichen Verfahren zum Falzen eines Randes mit und ohne einem im Falz einzuklemmenden Rand eines anderen Blechbauteils erfolgt das Umfalten des abgewinkelten Randes in mehreren Stufen mittels einer Falzrolle, deren Mantel zylindrisch ist. Selbst bei diesem mehrstufigen Umfalten entwickelt sich bei höherer Laufgeschwindigkeit eine der Falzrolle vorauseilende Materialwelle, die bei Überschreiten einer kritischen Geschwindigkeit dazu fuhrt, dass die Falzrolle die Materialwelle überspringt, was zu Falzfehlern führt. Deshalb ist die Laufgeschwindigkeit der Falzrolle je nach Dicke des zu falzenden Bleches auf 200 mm/s beschränkt.In the usual practice in practice for folding an edge with and without an edge to be clamped in the fold of another sheet metal component, the folded edge is folded in several stages by means of a folding roller whose shell is cylindrical. Even with this multi-stage folding develops at higher running speed of the folding roller leading material wave, which leads at a critical speed to the fact that the folding roller the Material wave skips, which leads to folding errors. Therefore, the running speed of the folding roller is limited to 200 mm / s depending on the thickness of the sheet to be folded.
Ein Verfahren zum Falzen eines Randes eines Blechbauteils der eingangs genannten Art ist bekannt (EP 1 445 043 Al, Fig. 4 und 5 mit zugehörigem Text) . Bei diesem Verfahren ist die konisch konturierte Rolle mit ihrer Rotationsachse nur schief zur Ebene des zu falzenden Blechbauteils angestellt. Daraus ergibt sich ein vergleichsweise kurzer Abschnitt des Faltvorganges in Bewegungsrichtung der Rolle. Deshalb sind erhebliche Umformkräfte erforderlich, und es besteht die Gefahr eines nicht optimalen Falzergebnisses.A method for folding an edge of a sheet metal part of the type mentioned is known (EP 1 445 043 Al, Fig. 4 and 5 with associated text). In this method, the conically contoured roller is employed with its axis of rotation only obliquely to the plane of the sheet metal component to be folded. This results in a comparatively short section of the folding process in the direction of movement of the roller. Therefore, considerable forming forces are required, and there is a risk of a non-optimal folding result.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Falzen zu schaffen, das mit hoher Falzgeschwindigkeit und hoher Prozesssicherheit ausgeführt werden kann.The invention has for its object to provide a method for folding, which can be performed with high folding speed and high process reliability.
Diese Aufgabe wird bei einem Verfahren der eingangs genannten Art dadurch gelöst, dass die Falzrolle bezüglich ihrer Rotationsachse zusätzlich schief zur Bewegungsrichtung angestellt ist.This object is achieved in a method of the type mentioned above in that the folding roller is also employed with respect to its axis of rotation obliquely to the direction of movement.
Beim erfindungsgemäßen Falzverfahren erfolgt das Umfalten des Falzes einstufig. Wegen der besonderen Form der Falzrolle und ihrer windschiefen (zweimal schief: schiefe Anstellung ihrer Rotationsachse a) zur Ebene des Blechbauteils und b) zu ihrer Bewegungsrichtung) Anstellung greift diese über eine längere Strecke am umzulegenden Rand als eine mit ihrer Achse senkrecht zur Bewegungsrichtung angestellten, zylindrischen Falzrolle an. Deshalb bildet sich im Gegensatz zu einem Verfahren mit einer zylindrischen Rolle auch keine vorauseilende Materialwelle wie beim Stand der Technik, mit der Folge, dass es zu Falzfehlern kommt. Das bringt den weiteren Vorteil mit sich, dass das erfindungsgemäße Verfahren mit vergleichsweise hoher Falzgeschwindigkeit durchgeführt werden kann, z.B. mit mindestens 800m/sec, insb. 1200 m/sec und mehr.When folding method according to the invention, the folding of the fold takes place in one stage. Because of the special shape of the folding roller and its skewed (twice oblique: oblique position of its axis of rotation a) to the plane of the sheet metal component and b) to their direction of movement employment this engages over a longer distance on umzulegenden edge as a staff with their axis perpendicular to the direction of movement, cylindrical folding roll on. Therefore, in contrast to a method with a cylindrical roller, no anticipatory forms Material shaft as in the prior art, with the result that it comes to folding errors. This has the further advantage that the method according to the invention can be carried out with a comparatively high folding speed, for example with at least 800 m / sec, in particular 1200 m / sec and more.
Besonders günstig für den Falzvorgang wirkt sich aus, wenn der konische Mantelbereich die Kontur einer Hohlkehle hat. Vorzugsweise entspricht dann die Kontur einer halben Parabel. Die Kontur muss allerdings nicht im streng mathematischen Sinn parabelförmig sein; auch andere Konturen sind denkbar. Z. B eine Traktrix-Kurve, auch Schlepp-/Treidelkurve genannt.Particularly favorable for the folding process has an effect if the conical jacket region has the contour of a groove. Preferably, then the contour corresponds to half a parabola. However, the contour does not have to be parabolic in the strictly mathematical sense; Other contours are conceivable. Z. B a Traktrix curve, also called tow / Treidelkurve.
Die Falzrolle ist vorzugsweise angetrieben.The folding roller is preferably driven.
Das erfindungsgemäße Rollfalzverfahren funktioniert besonders gut, wenn sich an den konischen Bereich im wesentlichen zylindrische Randbereiche anschließen.The roll-folding method according to the invention works particularly well when substantially cylindrical edge regions adjoin the conical region.
Es versteht sich, dass die konkrete geometrische Kontur der Rolle und ihrer Anstellung von dem Falz, seiner Materialdicke und dem Fließverhalten des Materials abhängt. Der Anwender kann die optimale Kombination der Parameter aber durch Betriebsversuche leicht ermitteln. Die relativen geometrischen Verhältnisse und Bewegungen zwischen der Falzrolle und dem zu falzenden Rand lassen sich auf mannigfache Weise realisieren. So kann der Rand ortsfest gehalten und die Rolle bewegt und angestellt werden oder umgekehrt oder eine Kombination daraus. Die dabei eingesetzten Mittel können Schlitten, Schienen Antriebs- und Führungs- und Stellmittel (Roboter) sein. Im Folgenden wird die Erfindung anhand einer ein konkretes Ausführungsbeispiel darstellenden Zeichnung näher erläutert. Im Einzelnen zeigen:It is understood that the concrete geometric contour of the roll and its setting depends on the fold, its material thickness and the flow behavior of the material. However, the user can easily determine the optimum combination of the parameters by operating tests. The relative geometric relationships and movements between the seaming roller and the edge to be folded can be realized in manifold ways. Thus, the edge can be held stationary and the role moved and hired or vice versa, or a combination thereof. The means used can be carriages, rails, driving and guiding and adjusting means (robots). In the following the invention will be explained in more detail with reference to a drawing illustrating a concrete embodiment. In detail show:
Fig. 1 eine Falzrolle und ein zu falzendes Blechbauteil während des Falzvorgangs in perspektivischer Ansicht aus der Gegenrichtung zur Bewegungsrichtung undFig. 1 is a folding roller and a sheet metal component to be folded during the folding process in a perspective view from the opposite direction to the direction of movement and
Fig. 2 die Falzrolle im Axialschnitt.Fig. 2, the folding roller in axial section.
Das erfindungsgemäße Verfahren lässt sich an einem Blechbauteil mit einem einfachen Falz oder an einem Blechbauteil unter Einschluss eines weiteren Blechbauteils durchführen. Das Ausführungsbeispiel zeigt ein Verfahren zum Falzen eines einfachen Falzes.The method according to the invention can be carried out on a sheet-metal component with a simple fold or on a sheet-metal component with the inclusion of a further sheet-metal component. The embodiment shows a method for folding a simple fold.
Dazu ist das Blechbauteil 1 mit einem abgewinkelten hoch stehenden Rand 2 auf einem Bett 3 örtlich festgelegt. Das Bett 3 kann stationär angeordnet sein, aber auch bewegt werden, je nachdem, welche Bauteile gefalzt werden sollen .For this purpose, the sheet metal part 1 with a bent upstanding edge 2 on a bed 3 is fixed locally. The bed 3 may be stationary but may also be moved, depending on which components are to be folded.
Oberhalb des Bettes 3 ist eine konturierte freilaufende oder angetriebene Falzrolle 4 in Längsrichtung des Randes 2 und parallel zu diesem verfahrbar gelagert. Die dafür erforderlichen Antriebs- und Führungsmittel sind in der Zeichnung nicht dargestellt. Die Mantelfläche 5 der Falzrolle 4 setzt sich aus zwei äußeren Randbereichen 5a, 5b und einem mittleren Bereich 5c zusammen, wobei die äußeren Randbereiche 5a, 5b eine zylindrische Form und der für den Falzvorgang hauptsächlich verantwortliche, mittlere Bereich 5c die Form eines Konus hat. Konkret hat der mittlere Bereich 5c die Kontur einer Hohlkehle, deren Erzeugende eine halbe Parabel ist, wobei der die Hohlkehle aufweisende mittlere Bereich 5c auf der einen Seite über eine Stufe am äußeren Bereich 5a des größten Durchmessers der Falzrolle 4 endet und auf der anderen Seite stufenlos in den äußeren Bereich 5b des kleinsten Durchmessers übergeht.Above the bed 3 is a contoured freewheeling or driven folding roller 4 in the longitudinal direction of the edge 2 and mounted parallel to this movable. The required drive and guide means are not shown in the drawing. The lateral surface 5 of the seaming roller 4 is composed of two outer edge regions 5a, 5b and a central region 5c, the outer edge regions 5a, 5b having a cylindrical shape and the middle region 5c, which is mainly responsible for the folding process, in the form of a cone. Has concrete the central region 5c is the contour of a groove, the generatrix of which is half a parabola, the middle region 5c having the groove ending on one side via a step on the outer region 5a of the largest diameter of the seaming roller 4 and steplessly on the other side outer region 5b of the smallest diameter merges.
Eine solche Falzrolle 4 lässt sich mittels der nicht dargestellten Führungs- und Anstellmittel derart windschief zu ihrer Bewegungsrichtung längs des Falzes anstellen, dass sie bei ihrer Bewegung zunächst mit ihrer voreilenden Seite ihres äußeren Bereichs 5a ihres größten Durchmessers an dem hochstehenden Rand 2 angreift und damit den Umlegvorgang einleitet. Der Rand 2 gleitet dann weiter über den mittleren Bereich 5c, wobei er weiter umgelegt wird, bis dass er endlich mit dem Bereich 5b ihres kleinsten Durchmessers zur Anlage am ebenen Blechbauteil 1 gedrückt wird. Je nach Kontur der Falzrolle 4 lassen sich auf diese Weise flache, aber auch tropfenförmige Falze (z.B. Eurofalze) bilden. In jedem Fall erfolgt der Falzvorgang kontinuierlich und mit hoher Falzgeschwindigkeit. Die Falzung erfolgt somit einstufig, d.h. in einem Arbeitsschritt. Mehrstufige Falzschritte, wie sie aus dem beschriebenen Stand der Technik bekannt sind, sind nicht erforderlich. Die Gefahr von Falzfehlern ist wegen der besonderen Form und Anstellung der Falzrolle 4 minimiert. Such a folding roller 4 can be so oblique to the direction of movement along the fold by means of the guide and adjusting means, not shown, that it initially attacks with its leading side of its outer portion 5a of its largest diameter on the upstanding edge 2 and thus the Relocation procedure initiates. The edge 2 then slides on over the central region 5c, where it is further folded over until it is finally pressed with the region 5b of its smallest diameter for engagement with the planar sheet-metal component 1. Depending on the contour of the seaming roller 4, flat but also drop-shaped folds (for example, Eurofalze) can be formed in this way. In any case, the folding takes place continuously and at high folding speed. The fold is thus one-step, i. in one step. Multi-stage folding steps, as known from the described prior art, are not required. The risk of folding errors is minimized because of the special shape and employment of the seaming roller 4.
