Abstract
Description
Die Erfindung betrifft sandwichartige Metallverbundplatten und ein Verfahren zu ihrer Herstellung.The The invention relates to sandwich-type metal composite panels and a method for their production.
Verfahren zur Herstellung von sogenannten Sandwichplatten die vorzugsweise im Leichtbau verwendet werden sind aus dem Stand der Technik an sich bekannt.method for the production of so-called sandwich panels preferably be used in lightweight construction are from the prior art in itself known.
Beispielsweise werden dünne Metalltafeln mit dazwischen liegender Kunststoff- oder Metallschicht die auch wabenförmig sein kann verklebt. Auch Verfahren bei denen die Zwischenschicht aus organischem oder anorganischem Material geschäumt wird sind bekannt.For example become thin Metal panels with intervening plastic or metal layer which also honeycomb can be glued. Also methods where the intermediate layer foamed from organic or inorganic material are known.

Die
Nachteilig bei den bisher bekannten Verfahren ist jedoch der Umstand, daß die Verbundplatten entweder leicht und steif aber nur sehr aufwendig weiterverarbeitbar oder relativ schwer und teuer herstellbar sind.adversely However, in the previously known methods is the fact that the composite panels either light and stiff but only very elaborate weiterverarbeitbar or are relatively difficult and expensive to produce.
Der Erfindung liegt die Aufgabe zu Grunde ein Verfahren anzugeben, welches unter Vermeidung der vorgenannten Nachteile die kostengünstige Herstellung von Metallverbundplatten erlaubt die leicht und steif und einfach weiterverarbeitbar sind.Of the The invention is based on the object of specifying a method which while avoiding the aforementioned disadvantages, the cost-effective production of metal composite panels allows the light and stiff and easy are processable.
Die Erfindung löst die Aufgabenstellung durch die Merkmale wie sie im Patentanspruch 1 und 2 und den Unteransprüchen beschrieben sind.The Invention solves the task by the features as in the claim 1 and 2 and the dependent claims are described.
Der Plattenverbund wird dadurch bewirkt, daß nach einer Vorbehandlung, die aus einer sauren oder auch alkalischen Entfettung, optional einer zusätzlichen Beize zur Rostentfernung und meist auch einer Flußmittelbehandlung besteht, die fixierten Teile in flüssiges Metall, beispielsweise auf etwa 450° erhitztes Zink, getaucht werden. An den Kontaktstellen der Teile untereinander entstehen Brücken aus Metall und an den Phasengrenzen Legierungen die eine haftfeste Schicht bilden. Die Tauchzeit beträgt nur wenige Sekunden und danach kann mit Wasser abgeschreckt werden. Durch diese chemische Metallabscheidung, auch Feuerverzinkung genanntes Verfahren entsteht in sehr kurzer Zeit ein mechanisch stabiler Verbundkörper mit gutem Korrosionsschutz.Of the Plate composite is effected in that after pretreatment, those from an acidic or even alkaline degreasing, optional an additional one Stain for rust removal and usually also a flux treatment consists, the fixed parts in liquid metal, for example heated to about 450 ° Zinc, to be dipped. At the contact points of the parts with each other arise bridges made of metal and at the phase boundaries alloys the one sticky Forming a layer. The dive time is only a few seconds and afterwards it can be quenched with water. By this chemical Metal deposition, also called hot dip galvanizing process arises in a very short time a mechanically stable composite body with good corrosion protection.
Bei temperaturempfindlichen Werkstoffen kann vorzugsweise die elektrochemische Metallabscheidung angewandt werden die sich durch niedrige Temperaturen und große Vielfalt bei den abscheidbaren Metallen auszeichnet. Die fixierten Teile werden in einer wässrigen Salzlösung elektrolytisch beschichtet indem sich auf den als Kathode geschalteten Werkstücken bei etwa 0,5 – 2,5 A/dm2 eine Metallschicht abscheidet.In the case of temperature-sensitive materials, electrochemical metal deposition, which is characterized by low temperatures and a great variety of depositable metals, can preferably be used. The fixed parts are electrolytically coated in an aqueous salt solution by depositing a metal layer on the workpieces connected as cathode at about 0.5-2.5 A / dm 2 .
Das erfindungsgemäße Verfahren ermöglicht insbesondere die Verwendung perforierter Metallplatten, Gittermatten, Metallgewebe, Drahtgeflechte, Streckgitter und Streckmetallplatten als Zwischenlage oder Deckplatten.The inventive method allows in particular the use of perforated metal plates, lattice mats, Metal mesh, wire mesh, expanded metal mesh and expanded metal sheets as intermediate layer or cover plates.
Zusammengesetzte flächige Strukturen wie Gitterroste, Lamellenraster und Waben etc. eignen sich bevorzugt als Zwischenlagen aber auch als Deckplatten.Compound area Structures such as gratings, lamellae and honeycomb etc. are suitable preferably as intermediate layers but also as cover plates.
Die Werkstoffe beschränken sich nicht auf Metalle, es können auch andere elektrisch leitfähige Materialien, leitfähig beschichtete Materialien, beispielsweise metallisierte Kunststoffe, Keramik oder Gläser verwendet werden.The Restrict materials not on metals, it can also other electrically conductive materials, conductive coated materials, for example metallised plastics, Ceramics or glasses be used.
Besondere Gestaltungsmöglichkeiten bietet die Verwendung von Streckmetallplatten als Zwischenplatten. Durch deren gezielte Streckung kann die Geometrie der Maschen so beeinflußt werden, daß das Widerstandsmoment gegen Durchbiegung maximal wird. Die Verformung der vorzugsweise nicht flachgewalzten Streckmetallplatte durch profilieren, tiefziehen, prägen und ähnliche an sich bekannte Umformprozesse führt zu mehr oder weniger stark strukturierten Platten die den Verbundplatten spezifische Eigenschaften verleihen.Special design options offers the use of expanded metal plates as intermediate plates. By their targeted stretching the geometry of the mesh can so affected be that Resistance torque against deflection becomes maximum. The deformation the preferably not flat rolled expanded metal plate by profiling, deep-drawing, embossing and similar known forming processes leads to more or less strong textured panels give the composite panels specific properties to lend.
Die verformten Streckmetallplatten können Noppenprofile, Wellenprofile, Waben etc. aufweisen und einfach oder mehrfach übereinander angeordnet sein. Werden sie mehrfach übereinander angeordnet kann es vorteilhaft sein wenn sie sich kreuzende Wellenrichtungen bzw. Maschenrichtungen aufweisen.The deformed expanded metal plates can be nub profiles, Wave profiles, honeycombs, etc. and have one or more times one above the other be arranged. If they can be arranged several times one above the other be advantageous if they are crossing shaft directions or Have stitch directions.
