Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Herstellen eines Blechbauteils für einen Kraftwagen gemäß dem Oberbegriff von Patentanspruch 1. Des Weiteren betrifft die Erfindung ein Verfahren zum Herstellen eines Blechbauteils für einen Kraftwagen gemäß dem Oberbegriff von Patentanspruch 7.The invention relates to a device for producing a sheet metal component for a motor vehicle according to the preamble of claim 1. Furthermore, the invention relates to a method for producing a sheet metal component for a motor vehicle according to the preamble of patent claim 7.
Derartige Blechbauteile werden beispielsweise zur Beplankung von Personenkraftwagen in vielfältigster Ausführung eingesetzt, so insbesondere als Fronthauben oder dergleichen.
Zur Erhöhung der Qualität bzw. Qualitätsanmutung ist es heute wünschenswert, im Bereich des Blechfalzes kleine Bauteilradien zu schaffen. Dies ermöglicht nicht nur genaueste Bauteilkanten, sondern auch sehr genaue Spalte mit kleinen Spaltmaßen zu benachbarten Beplankungsteilen oder dgl. Um derartige Blechfalze herzustellen, kommt heute das Rollfalzen zum Einsatz, da hierdurch entsprechend kleine Bauteilradien zu schaffen sind. Dieses Verfahren ist jedoch mit einem großen Aufwand verbunden.To increase the quality or quality impression, it is now desirable to create small component radii in the area of the metal rebate. This not only allows the most accurate component edges, but also very accurate column with small gaps to adjacent Plankungsteilen or the like. In order to produce such Blechfalze, today Rollfalzen is used, as this accordingly small component radii are to create. However, this method is associated with a great deal of effort.
Aufgabe der vorliegenden Erfindung ist es daher, eine Vorrichtung und ein Verfahren der eingangs genannten Art zu schaffen, mittels welchem sich auf verbesserte und einfachere Weise ein Blechfalz mit einem kleinen Bauteilradius herstellen lässt.Object of the present invention is therefore to provide a device and a method of the type mentioned, by means of which can be produced in a better and easier way, a metal sheet with a small radius of the component.
Diese Aufgabe wird erfindungsgemäß durch eine Vorrichtung und ein Verfahren mit den Merkmalen der Patentansprüche 1 bzw. 7 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen Weiterbildungen sind in den übrigen Patentansprüchen angegeben.This object is achieved by a device and a method having the features of claims 1 and 7, respectively. Advantageous embodiments with expedient developments are specified in the remaining claims.
Um eine Vorrichtung der eingangsgenannten Art zu schaffen, mittels welcher sich auf verbesserte Weise ein Blechfalz mit kleinem Bauteilradius herstellen lässt, ist erfindungsgemäß der Umformbereich des Falzbackens mit einer Formschräge versehen, mittels welcher der Blechfalz unter Ausbildung eines Keilfalzes umformbar bzw. umfalzbar ist. Hierzu ist es denkbar, dass der Blechfalz bereits beim Umfalzen um das Innenteil mit einem entsprechenden Keilfalz versehen wird. Denkbar ist es jedoch insbesondere auch, dass der Blechfalz zunächst in einem oder mehreren Falzschritten zu einem Flachfalz, Tropfenfalz oder dgl. mit einer beispielsweise runden Falzschlaufe um das Innenteil herum umgefalzt und anschließend und einem weiteren Schritt, üblicherweise dem Fertigfalzschritt, die beispielsweise runde Falzschlaufe durch die Vorrichtung bzw. den Falzbacken zur Keilform umgefalzt wird.In order to provide a device of the type mentioned above, by means of which a sheet metal fold with small component radius can be produced in an improved manner, according to the invention the forming region of the seaming jaw is provided with a draft, by means of which the sheet metal seam is deformable or formable to form a Keilfalzes. For this purpose, it is conceivable that the Blechfalz is already provided during crimping around the inner part with a corresponding Keilfalz. However, it is also conceivable, in particular, for the sheet metal fold initially to be folded around the inner part in one or more folding steps to form a flat fold, drop fold or the like, and subsequently and for a further step, usually the finish fold step, through the round fold loop, for example the device or the folding jaws is folded over to the wedge shape.
Als weiterhin vorteilhaft hat es sich gezeigt, wenn der Falzbacken einen Stützbereich zur Führung entlang des Falzbetts aufweist, welcher quer und insbesondere senkrecht zum Umformbereich verläuft. Da somit der Falzbacken mit dem Stützbereich mit vorzugsweise geringem Spiel an der Falzbettseite anliegt, kann das Material des Falzbogens nicht ausweichen und wird beim Keilfalzen an den Umformbereich, also dem Formgebungsabschnitt des Falzbackens, weitestgehend konturgetreu gepresst.As further advantageous, it has been shown that the folding jaws has a support region for guiding along the folding bed, which extends transversely and in particular perpendicular to the forming area. Thus, since the folding jaws with the support region with preferably a small clearance on the Falzbettseite rests, the material of the signature can not dodge and is pressed during Keilfalzen to the forming area, ie the shaping section of the folding jaw, as far as possible contour.
Weiterhin vorteilhaft ist es, wenn die Formschräge mit jeweiligen Radien in den Stützbereich und den Umformbereich übergeht. Vorzugsweise handelt es sich dabei um sogenannte sanfte Radien, so dass das Blech in diesem Bereich nicht übermäßigen Umformkräften ausgesetzt wird.It is also advantageous if the draft merges with respective radii in the support region and the forming region. Preferably, these are so-called gentle radii, so that the sheet is not exposed to excessive forming forces in this area.
Das Innenteil und das Außenteil sind in weiterer Ausgestaltung der Erfindung mittels des Falzbetts und eines gegenüberliegenden Druckelements fixierbar. Somit wird das Innenteil gegen das Außenbeplankungsteil gedrückt, so dass keine Positionsverschiebungen der Bauteile während des Falzens auftreten können. Des Weiteren kann das Druckelement, welches insbesondere als Druckrahmen ausgebildet ist, in vorteilhafter Weise als Führung für den Falzbacken dienen, wodurch sich eine insbesondere konturtreue Herstellung des Blechbauteils realisieren lässt.The inner part and the outer part can be fixed in a further embodiment of the invention by means of the folding bed and an opposite pressure element. Thus, the inner part is pressed against the Außenbeplankungsteil, so that no positional shifts of the components can occur during folding. Furthermore, the pressure element, which is designed, in particular, as a pressure frame, can advantageously serve as a guide for the folding jaw, as a result of which a production of the sheet metal component that is particularly consistent in contour can be achieved.
Die vorstehend im Zusammenhang mit der erfindungsgemäßen Vorrichtung beschriebenen Vorteile gelten in ebensolcher Weise für das Verfahren gemäß Patentanspruch 7. Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispiels sowie anhand der Zeichnungen; diese zeigen in:The advantages described above in connection with the device according to the invention apply equally to the method according to claim 7.
