Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstellung glänzender Leichtmetall-Verbundbleche, insbesondere Luft fahrtbleche, mit eine Kernschicht aus einer aushärtbaren Aluminiumlegierung und einer ein- oder beidseitigen kathodi schen Korrosionsschutzschicht aus einem unedleren Material auf Aluminiumbasis Es ist bekannt, Bleche dieser Art mit den Verfahrens schritten gemäß Oberbegriff des Patentanspruchs 1 herzustel len.The invention relates to a method for manufacturing shiny light metal composite sheets, especially air driving plates, with a core layer made of a curable Aluminum alloy and a cathodi on one or both sides corrosion protection layer made of a less noble material based on aluminum It is known to sheet metal of this type using the process steps according to the preamble of claim 1 len.
Der Kernwerkstoff ist typischerweise eine AlCu(Mg)-Le gierung mit der Bezeichnung AA2XXX bzw. eine AlZnMg(Cu)- Legierung mit der Bezeichnung AA7XXX. Als Werkstoff für die Korrosionsschutzschicht wird üblicherweise Reinaluminium für die 2XXX-Legierung oder eine AlZn1-Legierung mit der Be zeichnung 7072 für den Kernwerkstoff AA7XXX verwendet.The core material is typically an AlCu (Mg) -Le alloy with the designation AA2XXX or an AlZnMg (Cu) - Alloy called AA7XXX. As a material for the Corrosion protection layer is usually made of pure aluminum the 2XXX alloy or an AlZn1 alloy with the Be drawing 7072 is used for the core material AA7XXX.
Im Rahmen des bekannten Verfahrens erfolgt seit Jahr zehnten das Glänzen des Blechs nach dem Auslagern durch mechanisches Polieren. Dieser Vorgang ist sehr arbeitsauf wendig. Das Blech wird mittels Stoffbürsten und Diamantpaste poliert. Nachteilig ist, daß die Blechoberfläche eine deut liche Polierstruktur und ein graues Erscheinungsbild zeigt. Darüber hinaus verringert sich die Dicke der Korrosions schutzschicht durch den mechanischen Abtrag örtlich un gleichmäßig, so daß auch der durch die kathodische, d. h. gegenüber dem Kernwerkstoff unedlere, Korrosionsschutz schicht bewirkte Korrosionsschutz örtlich ungleichmäßig ist. Darüber hinaus ergibt sich durch Schleif- und Polierfehler ein Ausschuß bis zu 20% der angelieferten Bleche. Der Po liermittelabfall ist nachteiligerweise als Sondermüll zu entsorgen, da er mit Schleifmittel und Aluminiumabrieb kon taminiert ist.As part of the known method has been taking place for years tenth through the shine of the sheet after aging mechanical polishing. This process is very busy agile. The sheet is made using fabric brushes and diamond paste polished. It is disadvantageous that the surface of the sheet is clear polishing structure and a gray appearance. In addition, the thickness of the corrosion decreases protective layer due to the mechanical removal locally and evenly, so that the cathodic, d. H. corrosion protection less noble than the core material layer caused corrosion protection is locally uneven. In addition, there are grinding and polishing errors a reject up to 20% of the delivered sheets. The bottom Solvent waste is disadvantageously considered to be hazardous waste dispose of it as it contains abrasives and aluminum debris is damaged.
Aufgabe der Erfindung ist es, das Verfahren gemäß Ober begriff des Patentanspruchs 1 so zu gestalten, daß sich bei verringertem Arbeitsaufwand ein verbessertes Glanzergebnis erzielen läßt.The object of the invention is the method according to Ober Concept of claim 1 to be designed so that at reduced workload an improved gloss result can be achieved.
Diese Aufgabe wird erfindungsgemäß mit einem Verfahren mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved with a method solved with the features of claim 1.
Bevorzugt wird ein einziger Nachwalzschritt durchge führt, der in einem Arbeitsgang gleichzeitig der Gefügever besserung und der Glanzerzeugung dient.A single re-rolling step is preferably carried out leads the structure structure in one work step improvement and the generation of gloss.
Soll das Blech nur einseitig hochglänzend sein, so wird im Glanzwalzschritt als Unterwalze eine Walze mit rauherem Schliff verwendet.If the sheet should only have a high gloss finish on one side, then in the gloss roller step as a bottom roller, a roller with rougher Cut used.
Wenngleich der Walzpoliervorgang auf einer weichen Oberfläche durchgeführt wird, ist das optische Erscheinungs bild gegenüber dem bekannten mechanischen Polieren maßgeb lich verbessert. Der Glanzwert, gemessen nach Dr. Lange, erhöht sich auf GW 60 bis GW 70 gegenüber GW 50 beim mecha nischen Polieren. Der Ausschuß verringert sich praktisch auf null, was zu einer erheblichen Verringerung der Herstel lungskosten führt. Darüber hinaus entsteht nach dem erfin dungsgemäßen Verfahren beim Polieren nahezu kein Abfall, so daß sich die Umweltbelastung und die Entsorgungskosten ver ringern.Although the roll polishing process on a soft Surface is done is the visual appearance image compared to the known mechanical polishing Lich improved. The gloss value, measured according to Dr. Long, increases to GW 60 to GW 70 compared to GW 50 for mecha African polishing. The committee is practically reduced to zero, resulting in a significant reduction in manufac costs. In addition, according to the inventions process according to the invention during polishing almost no waste, so that the environmental impact and the disposal costs ver wrestle.
Entgegen dem vorbekannten Verfahren erfolgt der Walz vorgang vorzugsweise in Bandform. Das Plattierwalzen über mehrere Stiche folgt vorzugsweise mit verringerten Rauhig keiten der Walzen und unter Zwischenbeizung. Die Stichabnah me liegt zwischen 0,5 und 30%, wobei die Walzgeschwindig keit bis zu 400 m/min beträgt.Contrary to the previously known method, the rolling takes place operation preferably in tape form. The plating rolling over multiple stitches preferably follows with reduced roughness of the rollers and with intermediate pickling. The stitch decrease me is between 0.5 and 30%, the rolling speed speed is up to 400 m / min.
