Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung eines Blechteils gemäß dem Oberbegriff des Patentanspruches.The The present invention relates to a process for producing a Sheet metal part according to the preamble of the claim.
Türen und Klappen von Fahrzeugen werden üblicherweise aus mehreren Blechen hergestellt. Bei Fahrzeugtüren und Klappen ist es üblich, einzelne Bleche durch Bördeln miteinander zu verbinden. Zur Verbesserung der Bauteilfestigkeit und zur Verringerung der Korrosionsanfälligkeit der Bördelfalze werden die Bleche im Falzbereich zusätzlich miteinander verklebt. Üblicherweise wird zunächst auf die Innenseite des Außenhautblechs eine Klebstoffraupe aufgetragen. Anschließend wird das Innenblech auf das Außenhautblech aufgebracht, derart, dass ein Rand des Außenhautblechs über das Innenblech vorsteht. Anschließend wird der Rand des Außenhautblechs um das Innenblech umgebördelt. Zusätzlich wird üblicherweise der umgebördelte Rand noch mit einer Klebstoffraupe versiegelt.Doors and Flaps of vehicles become common made of several sheets. For vehicle doors and flaps, it is common to individual sheets by beading to connect with each other. To improve component strength and to reduce the susceptibility to corrosion of the crimp folds If the sheets are additionally glued together in the rebate area. Usually will be first on the inside of the outer skin panel applied an adhesive bead. Then the inner panel is opened the outer skin sheet applied, such that an edge of the skin panel over the Inner plate protrudes. Subsequently The edge of the outer skin sheet is about the inner panel flanged. additionally becomes common the flanged Edge still sealed with a bead of glue.
Mit dem oben beschriebenen Verfahren ist es nur aschwer möglich, einen technisch bzw. qualitativ einwandfreien Bördelfalz herzustellen, der vollständig mit Klebstoff gefüllt ist. Arbeitet man mit einer großen Klebstoffmenge, so besteht stets die Gefahr, dass der Klebstoff während des Umbördelns des Außenhautblechs aus dem Bördelfalz austritt und das herzustellende Bauteil sowie das Bördelwerkzeug verschmutzt, was eine aufwändige manuelle Reinigung erforderlich macht und daher für eine Großserienfertigung ungeeignet ist. Arbeitet man mit einer geringeren Klebstoffmenge, so besteht stets die Gefahr, dass die Bördelflansche nicht vollständig mit Klebstoff gefüllt sind, was eine Hauptursache für Korrosion ist.With the method described above, it is only a hard way, a produce technically or qualitatively flawless edging, the Completely filled with glue is. Do you work with a big one Adhesive amount, so there is always the risk that the adhesive while of flanging the outer skin sheet from the crimp fold leaking and the component to be manufactured as well as the flanging tool dirty, which is an elaborate one Manual cleaning is required and therefore for mass production is unsuitable. If you work with a smaller amount of glue, so there is always the danger that the flare flanges not completely with Adhesive filled are what a major cause of Corrosion is.
Aufgabe der Erfindung ist es, ein Verfahren zur Herstellung eines gebördelten Blechteils anzugeben, das einen hohen Füllungsgrad des Bördelfalzes mit Klebstoff ermöglicht und bei dem ein Austreten überschüssigen Klebstoffs aus dem Bördelfalz vermieden wird.task The invention is a method for producing a flanged Specify sheet metal part, which has a high degree of filling of the edging fold Adhesive allows and in which leakage of excess adhesive from the crimp fold is avoided.
Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.These The object is solved by the features of claim 1. advantageous Refinements and developments of the invention are the dependent claims remove.
Ausgangspunkt der Erfindung sind die an sich bekannten Verfahrensschritte, bei denen auf ein erstes Blech ein zweites Blech aufgebracht wird und ein Rand des ersten Blechs um einen Randbereich des zweiten Blechs umgebördelt wird, wodurch ein Bördelfalz entsteht. Der Kern der Erfindung besteht darin, dass erst nach dem Umbördeln des ersten Blechs von mindestens einem Ende des Bördelfalzes her Klebstoff in den Bördelfalz injiziert wird. Sofern der verwendete Klebstoff hinreichend flüssig ist, breitet sich dieser aufgrund von Kapillarkräften gleichmäßig im Bördelfalz aus. Ein Austritt von Klebstoff aus dem Bördelfalz, wie dies bei herkömmlichen Herstellungsverfahren zu beobachten ist, wird vermieden.starting point The invention relates to the method steps known per se which a second sheet is applied to a first sheet and a Edge of the first sheet is flanged around an edge region of the second sheet, causing a hemmed fold arises. The essence of the invention is that only after the flanging the first sheet of at least one end of the edging fold ago Adhesive in the edging fold is injected. If the adhesive used is sufficiently liquid, this spreads evenly in the hem flange due to capillary forces out. A leakage of adhesive from the edging fold, as in conventional Manufacturing process is observed is avoided.
Zur Unterstützung der Ausbreitung des Klebstoffs im Bördelfalz kann der Klebstoff unter Druck, z.B. mittels Pressluft, in den Bördelfalz injiziert werden. Denkbar ist jedoch auch, dass der Klebstoff von einer in Bezug auf die Schwerkraft oberen Stelle her in das Blechteil bzw. in den Bördelfalz injiziert wird und sich ausschließlich aufgrund von Kapillarkräften und der Schwerkraft im Bördelfalz verteilt.to support the spread of the adhesive in the hem flange may be the adhesive under pressure, e.g. be injected by means of compressed air into the edging fold. However, it is also conceivable that the adhesive of a respect to the gravity upper point forth in the sheet metal part or in the edging fold is injected and solely due to capillary forces and of gravity in the crimp fold distributed.
Zur Verbesserung des Fließverhaltens kann das Bauteil vor und/oder während des Injizierens des Klebstoffs angewärmt werden, z.B. bis auf ca. 80°C.to Improvement of the flow behavior can the component before and / or during of injecting the adhesive, e.g. except for approx. 80 ° C.
Das Aushärten des Klebstoffs kann auf verschiedene Weise erfolgen, z.B. anerob, durch eine Zwei-Komponenten-Reaktion im Falle eines Zwei-Komponenten-Klebstoffs, durch Einbringung von Wärme, etc.The Harden The adhesive can be made in various ways, e.g. anaerobically, by a two-component reaction in the case of a two-component adhesive, by the introduction of heat, Etc.
Im Folgenden wird die Erfindung im Zusammenhang mit der Zeichnung näher erläutert. Es zeigen:in the The invention will be explained in more detail in connection with the drawing. It demonstrate:
