Abstract

The system produces a composite plate consisting of two relatively stiff flat components, typically of sheet metal and forming the covering layers, and having flanged edges, and an intermediate layer. Two similarly shaped parts are used as the flat components (1, 2). Their flanged edges (5, 6) are bent at an angle (alpha) to them dependent on their material thickness (m) and the desired distance (a) between them. The angle can be determined by a formula based on this thickness and distance, and also on the distance(s) between the flanges. The formula is (alpha) = arc. sin (m+s)/(a+m).

Description

Verfahren zum Herstellen einer VerbundplatteMethod of manufacturing a composite panel

Die Erfindung betrifft ein Verfahren gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a method according to the preamble of the claim 1.

Die Vorteile von Verbundplatten wie geringes Gewicht, große Festigkeit, gute Wärmedämmung usw. sind bekannt und werden zum Großteil dort genutzt, wo ebene Platten, die in kostengünstigen,kontinuierlichen Verfahren hergestellt werden, einsetzbar sind. Verbundplatten mit Raumformen werden beispielsweise im Kraftfahrzeugbau für Motorhauben, Kofferraumdeckel etc., trotz der genannten Vorteile nur wenig verwendet, da die Kosten für die erforderliche Einzelherstellung relativ hoch sind.The advantages of composite panels such as light weight, great strength, good thermal insulation, etc. are known and are mostly used where flat Plates that are manufactured in cost-effective, continuous processes can be used are. Composite panels with three-dimensional shapes are used, for example, in automotive engineering Bonnets, trunk lids, etc., little used despite the advantages mentioned, since the costs for the required individual production are relatively high.

In einem bekannten Verfahren (FR-OS 75 27 689) werden zwei flächige Bauteile, die die Deckschichten einer Verbundplatte bilden, durch einen Wabenkörper verbunden. Die beiden flächigen Bauteile unterscheiden sich in der Ausbildung der Randbereiche zu unterschiedlichen Randflanschen, welche flächig aneinander liegen und verklebt werden. Diese Formung der flächigen Bauteile ist aufwendig und teuer.In a known method (FR-OS 75 27 689) are two flat Components that form the outer layers of a composite panel through a honeycomb body tied together. The two flat components differ in the design of the Edge areas to different edge flanges, which are flat against each other and glued. This shaping of the flat components is complex and expensive.

Aufgabe der Erfindung ist es, ein einfaches und kostengünstiges Verfahren zur Herstellung von Verbundplatten zu schaffen, die keine zusätzlichen Randverstärkungen benötigen und ein geschlossenes Teil bilden.The object of the invention is to provide a simple and inexpensive method to create composite panels that do not have additional edge reinforcements need and form a closed part.

Diese Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved with the features of claim 1.

Erfindungsgemäß haben beide flächigen Bauteile die gleiche Form und können daher mit dem gleichen Pressenwerkzeug hergestellt werden0 Dadurch ergibt sich vorteilhaft, daß nur ein Pressenwerkzeug gefertigt werden muß, keine Umrüstzeiten an den Pressen auftreten und die Lagerhaltungskosten durch die Lagerung nur eines Teiles reduziert werden können.According to the invention, both flat components have the same shape and can therefore be produced with the same press tool It is advantageous that only one press tool has to be manufactured, no retooling times occur at the presses and the storage costs due to the storage of only one Part can be reduced.

In der Ausführungsform nach Anspruch 2 liegen die Randflansche flächig parallel in einem bestimmten gewünschten Abstand, in den z. Bo eine Gummidichtleiste eingelegt werden kann, zueinander.In the embodiment according to claim 2, the edge flanges are flat parallel at a certain desired distance, in the z. Bo a rubber sealing strip can be inserted to each other.

Durch Bördeln eines Randfiansches um den anderen wird bei eingelegter Gummidichtleiste oder klebend der Innenraum der Verbundplatte auf einfache Weise abgedichtet und der Randbereich versteift. Beim Flanschabstand Null berühren sich die beiden Randflansche flächig und können somit einfach verklebt oder punktgeschweißt werden0 Anhand eines Ausführungsbeispiels wird die Erfindung im folgenden näher beschrieben Die Figur zeigt einen Schnitt durch eine Verbundplatte.By flanging one edge flange around the other, the inserted Rubber sealing strip or adhesive the interior of the composite panel in a simple way sealed and the edge area stiffened. When the flange distance is zero, they touch each other the two edge flanges are flat and can therefore easily be glued or spot welded will be0 Using an exemplary embodiment, the invention is presented in The figure shows a section through a composite panel.

Der Raum zwischen einem oberen flächigen Bauteil 1 und einem unteren flächigen Bauteil 2, die die Deckschichten einer Verbundplatte bilden, ist mit Schaumkunststoff 3 ausgeschäumt. Der Randflansch 5 des oberen flächigen Bauteils und der Randflansch 6 des unteren flächigen Bauteils liegen im Bereich b in einem Flanschabstand s parallel zueinander an einer Gummileiste 4. Der Randflansch 5 ist um den gekürzten Randflansch 6 gebördelt.The space between an upper flat component 1 and a lower one flat component 2, which form the outer layers of a composite panel, is made with foam plastic 3 foamed. The edge flange 5 of the upper flat component and the edge flange 6 of the lower flat component are parallel in area b at a flange distance s to each other on a rubber strip 4. The edge flange 5 is around the shortened edge flange 6 flanged.

Ein gewünschter Flanschabstand s, z. B. zum Einlegen der Gummi leiste 4, ergibt sich nur bei einem bestimmten AbkantwinkeltX in Abhängigkeit der Materialstärke m der Randflansche 5, 6 und des Abstands der Deckschichten a Dieser bestimmte Abkantwinkel o( ist richtig gewählt, wenn die Schnittlinie G des Randflansches 5 zugleich Tangente an den Kreis mit Biegeradius r1 um den Kreismittelpunkt M1 und an den äußeren Kreis mit Radius r2 um den Kreismittelpunkt M2 ist, wobei die Länge des Radius r2 gleich der Länge des Biegeradius r1 plus der Materialstärke m plus dem Flanschabstand s ist0 Der Abstand der Kreismittelpunkte ist gleich dem Abstand der Deckschichten a plus der Materialstärke s. Es ergibt sich für den Abkantwinkel folgende Abhängigkeit: m+s α = arcsin a+m' wobei m gleich der Materialstärke der Randflansche , s gleich dem Flanschabstand, a gleich dem Abstand der Deckschichten ist Für eine einfache Verklebung oder Punktschweißung der Randflansche im Bereich b ist normalerweise eine flächige Beruhrung der Randflansche erforderlich. Der Abkantwinkel OC ergibt sich dann durch Nullsetzen des Flanschabstandes s in obiger Formel Wird dieser ermittelte Abkantwinkel α nicht eingehalten, so klafft bei zu großem Abkantwinkel α ein Spalt zwischen Randflansch 5 und Randflansch 6, der nur schlecht mit unnötig viel Klebstoff verklebt werden kann. Bei zu kleinem Abkantwinkel α läßt sich das untere flächige Bauteil 2 nicht bis zu dem vorgegebenen Abstand a an das obere flächige Bauteil 1 heranbringen, da der Randflansch 5 im Wege steht und aufgebogen werden muß. Durch die Aufbiegung laufen aber Randflansch 5 und 6 nicht mehr parallel, so daß ebenfalls eine Spalte entsteht, die nur schlecht verklebt werden kann.A desired flange distance s, e.g. B. to insert the rubber bar 4, only results from a certain bending angle X depending on the material thickness m of the edge flanges 5, 6 and the distance between the cover layers a This particular bending angle o (is selected correctly if the cutting line G of the edge flange 5 is also a tangent to the circle with bending radius r1 around the center of the circle M1 and to the outer circle with radius r2 around the center of the circle M2, the length of the radius r2 being the same the length of the bending radius r1 plus the material thickness m plus the flange distance s ist0 The distance between the centers of the circle is equal to the distance between the cover layers a plus the material thickness s. The following dependency results for the bevel angle: m + s α = arcsin a + m 'where m is the same as the material thickness of the edge flange, s is the same the flange distance, a is equal to the distance between the cover layers For a simple Gluing or spot welding of the edge flanges in area b is normal flat contact with the edge flanges is required. The bevel angle OC results in This is then determined by setting the flange distance s to zero in the above formula Bending angle α not adhered to, so if the bending angle α is too large, there will be a gap a gap between edge flange 5 and edge flange 6, which is bad with unnecessary a lot of glue can be glued. If the chamfer angle α is too small, the lower planar component 2 not up to the predetermined distance a from the upper one Bring flat component 1 because the edge flange 5 stands in the way and is bent up must become. Due to the bend, however, edge flange 5 and 6 no longer run parallel, so that there is also a gap that can only be glued poorly.
