Description

Die Erfindung betrifft ein Verfahren zur Herstellung von Rollformprodukten durch Rollformen aus einem Band aus einer Aluminiumlegierung, wobei aus der Aluminiumlegierung hergestellte Bänder in Rollformern zu fertigen Produkten, wie beispielsweise Rollladenstäben, Dachfenster-, Paneel- und Fassadenbändern, profiliert werden. Aus dem Stand der Technik ist es bekannt, die entsprechenden Bänder für Rollformprodukte aus der Aluminiumlegierung AA 3005 herzustellen. Die Anforderungen an ein Band für Rollformprodukte bestehen im wesentlichen in der Biege- und Beulsteifigkeit, also der Stabilität des fertig profilierten Produktes, in sehr guten Verformungseigenschaften selbst bei kritischen Biegeradien (bei Rollladenbändern Biegeradius t=0), einer sehr guten Rollformbarkeit bei gleichzeitig sehr guter Lackanhaftung.The invention relates to a method for the production of rollform products by roll forming from a strip of an aluminum alloy, wherein produced from the aluminum alloy strips in roll formers to finished products, such as roller shutter bars, skylights, panel and facade tapes are profiled. From the prior art it is known to produce the corresponding tapes for roll forming products from the aluminum alloy AA 3005. The requirements for a strip for rollform products consist essentially in the bending and Beulsteifigkeit, ie the stability of the finished profiled product, in very good deformation properties, even at critical bending radii (in roller shutter belts bending radius t = 0), a very good roll formability at the same time very good paint adhesion.

Aus Gewichts- und Kostengründen werden zur Herstellung von Rollformprodukten zunehmend Bänder mit dünnerer Dicke, ≤ 0,3 mm, eingesetzt. Bei diesen Dicken weisen die Bänder für Rollformprodukte, die aus den aus dem Stand der Technik bekannten Legierungen hergestellt werden, Stabilitätsprobleme hinsichtlich Biege- und Beulsteifigkeit auf.For reasons of weight and cost, strips of thinner thickness, ≦ 0.3 mm, are increasingly being used for the production of rollform products. At these thicknesses, tapes for rollform products made from alloys known in the art exhibit stability problems with bending and buckling stiffness.

Aus der Broschüre " Aluminium mill products, general properties", Aluminium Pechiney Oktober 1986, S. 85 - 86 ist eine Aluminiumlegierung vom Typp AA3005 und deren Verwendung für Rollformprodukte bekannt. Allerdings erlaubt diese Legierung nur bei einer Dicke von 0,35mm einen Biegeradius von t=0. Bei Rollformprodukten werden jedoch auch bei Wandstärken von kleiner 0,3mm zunehmend kritische Biegradien mit t=0 gefordert.From the brochure " Aluminum Mill Products, General Properties ", Aluminum Pechiney October 1986, pp. 85-86 is a type AA3005 aluminum alloy and its use for rollform products known. However, this alloy allows only at a thickness of 0.35 mm a bending radius of t = 0. With rollform products, however, even critical wall radii with t = 0 are required even with wall thicknesses of less than 0.3 mm.

Ausgehend von den obigen Ausführungen liegt der Lehre der vorliegenden Erfindung die Aufgabe zugrunde, ein Verfahren zur Herstellung von Rollformprodukten zur Verfügung zu stellen, welches ein hohe Stabilität des fertig profilierten Produktes gewährleistet.Based on the above statements, the teaching of the present invention is based on the object of providing a method for the production of rollform products which ensures a high stability of the finished profiled product.

Die zuvor hergeleitete und aufgezeigte Aufgabe wird durch ein Verfahren mit den Merkmalen des Patentanspruchs 1 gelöst. Die Aluminiumlegierung zur Herstellung der Rollformprodukte weist die folgenden Legierungsanteile in Gewichtsprozenten auf :

  • 0,1 ≤ Si ≤ 0,5
  • 0,15 ≤ Fe ≤ 0,5
  • 0,05 ≤ Cu ≤ 0,25
  • 0,8 ≤ Min ≤ 1,4
  • 0,4 ≤ Mg ≤ 1,3
  • andere in Summe maximal 0,15, einzeln maximal 0,05,
  • Rest Al.
The previously derived and indicated object is achieved by a method having the features of patent claim 1. The aluminum alloy used to make the rollform products has the following percentages by weight in weight percent:
  • 0.1 ≦ Si ≦ 0.5
  • 0.15 ≤ Fe ≤ 0.5
  • 0.05 ≤ Cu ≤ 0.25
  • 0.8 ≤ Min ≤ 1.4
  • 0.4 ≤ Mg ≤ 1.3
  • others in total not more than 0.15, individually not more than 0.05,
  • Rest al.

Diese Aluminiumlegierung gewährleistet auch beim Einsatz dünner Metalldicken eine hohe Stabilität des fertig profilierten Produktes. Darüber hinaus weist die Legierung ausgezeichnete Verformungseigenschaften selbst bei kritischen Biegeradien, eine sehr gute Rollformbarkeit sowie eine sehr gute Lackanhaftung, aufgrund einer guten und glatten Metalloberfläche, nach der Umformung auf.This aluminum alloy ensures high stability of the finished profiled product even when using thin metal thicknesses. In addition, the alloy has excellent deformation properties even at critical bending radii, very good roll formability, and a very good paint adhesion, due to a good and smooth metal surface, after forming.

Ein vorteilhaftes Gefüge des Bandes für Rollformprodukte wird dadurch hergestellt, dass der Barren beim Vorwärmen des Warmwalzprozesses im Temperaturbereich von 480 bis 610°C für mindestens 3 Stunden geglüht wird und das Band beim Warmwalzen im Temperaturbereich von 270 bis 550°C gefertigt wird.An advantageous structure of the strip for rollform products is produced by annealing the billet during preheating of the hot rolling process in the temperature range of 480 to 610 ° C for at least 3 hours and the strip is produced during hot rolling in the temperature range of 270 to 550 ° C.

Dadurch, dass das Gefüge des Bandes 2 bis 10 Gussphasen pro 1000 µm2 mit einer maximalen Größe von 40 µm und einer mittleren Länge von 2 bis 6 µm, 500 bis 1200 feine Ausscheidungen pro 1000 µm2 sowie Restwiderstände im Bereich von 1,2 bis 2,5 µohm cm aufweist, ist gewährleistet, dass das Band gemäß der zweiten Lehre der Erfindung eine sehr gute Biegefähigkeit aufweist und Biegeradien von t=0 ohne Probleme zulässt und sich darüber hinaus durch eine sehr gute Weiterverarbeitung (= Rollformbarkeit) auszeichnet.Characterized in that the structure of the tape 2 to 10 casting phases per 1000 μ m 2 with a maximum size of 40 μ m and a mean length of 2 to 6 μ m, 500 to 1200 fine precipitates per 1000 μ m 2 and residual resistances in the range of 1.2 to 2.5 μohm cm, it is ensured that the tape according to the second teaching of the invention has a very good bending ability and bending radii of t = 0 without problems and, moreover, by a very good processing (= roll formability) distinguished.

Die Erfindung erfährt eine besonders vorteilhafte Ausgestaltung dadurch, dass das Band eine im Coil-Coating-verfahren aufgebrachte Lackschicht aufweist. Eine derartige im Coil-Coating-Verfahren aufgebrachte Lackschicht weist eine hervorragende Lackanhaftung auf, die gewährleistet, dass der Lack beim Rollformen sich nicht ablöst bzw. nicht beschädigt wird.The invention undergoes a particularly advantageous embodiment in that the band has a coating layer applied in the coil coating process. Such a coating layer applied in the coil coating process has an excellent paint adhesion, which ensures that the paint does not detach or become damaged during roll forming.

Es gibt nun eine Vielzahl von Möglichkeiten, das erfindungsgemäße Verfahren zur Herstellung von Rollformprodukten auszugestalten und weiterzubilden. Hierzu wird beispielsweise verwiesen einerseits auf die Patentansprüche andererseits auf die Beschreibung eines Ausführungsbeispiels für ein Rollformprodukt in Verbindung mit der Zeichnung.There are now a variety of ways to design and further develop the inventive method for the production of rollform products. For this purpose, for example, reference is made on the one hand to the claims on the other hand to the description of an embodiment of a rollform product in conjunction with the drawing.

In der Zeichnung zeigt die einzige Figur teilweise perspektivisch ein Schnitt durch ein Ausführungsbeispiel eines aus der erfindungsgemäßen Aluminiumlegierung hergestellten Rollformproduktes.In the drawing, the single FIGURE shows a perspective view, partly in section, of an exemplary embodiment of a roll-formed product produced from the aluminum alloy according to the invention.

Bei dem in der einzigen Figur dargestellten Rollformprodukt handelt es sich um einen Rollladenstab.The rollform product shown in the single figure is a roller shutter bar.

Dieser Rollladenstab wird, wie aus dem Stand der Technik bekannt, durch Rollformen aus einem Band für Rollformprodukte 1 hergestellt. Dieses Band für Rollformprodukte 1 besteht aus einer Aluminiumlegierung mit den folgenden Legierungsanteilen in Gewichtsprozenten:

  • 0,1 ≤ Si ≤ 0,5
  • 0,15 ≤ Fe ≤ 0,5
  • 0,05 ≤ Cu ≤ 0,25
  • 0,8 ≤ Mn ≤ 1,4
  • 0,4 5 ≤ Mg ≤ 1,3
  • andere in Summe maximal 0,15, einzeln maximal 0,05,
  • Rest Al.
This roller shutter rod is, as known from the prior art, produced by roll forming from a tape for rollform products 1. This tape for rollform products 1 consists of an aluminum alloy with the following proportions by weight in percent by weight:
  • 0.1 ≦ Si ≦ 0.5
  • 0.15 ≤ Fe ≤ 0.5
  • 0.05 ≤ Cu ≤ 0.25
  • 0.8 ≤ Mn ≤ 1.4
  • 0.4 5 ≤ Mg ≤ 1.3
  • others in total not more than 0.15, individually not more than 0.05,
  • Rest al.

Der Hohlraum des in der einzigen Figur dargestellten Rollladenstabes ist bei dem dargestellten Ausführungsbeispiel durch einen Kunststoffschaum 2 ausgefüllt.The cavity of the roller shutter bar shown in the single figure is filled in the illustrated embodiment by a plastic foam 2.

Besonders deutlich ist an der Position 3 die kritische Verformung mit einem Biegeradius von t=0 zu erkennen. Die Aluminiumlegierung gewährleistet eine derartige kritische Verformung am fertig lackierten Produkt.The critical deformation at a bending radius of t = 0 can be seen particularly clearly at position 3. The aluminum alloy ensures such critical deformation on the finished painted product.

Darüber hinaus gewährleistet die Verwendung der erfindungsgemäßen Aluminiumlegierung auch bei Metalldicken unterhalb von 0,3 mm eine gute Stabilität des Rollladenstabes.In addition, the use of the aluminum alloy according to the invention ensures a good stability of the roller shutter bar even with metal thicknesses below 0.3 mm.

Die Herstellung des Bandes für Rollformprodukte 1 erfolgt ausgehend vom Barren aus der Aluminiumlegierung durch Vorwärmung im Temperaturbereich von 480 bis 610°C bei einer Haltezeit von mindestens 3 Stunden, Warmwalzen im Temperaturbereich von 270 bis 550°C, Kaltwalzen und einer Wärmebehandlung.The production of the strip for rollform products 1 is carried out starting from the billet of aluminum alloy by preheating in the temperature range of 480 to 610 ° C with a holding time of at least 3 hours, hot rolling in the temperature range of 270 to 550 ° C, cold rolling and a heat treatment.

Das Band für Rollformprodukte weist nach dem Lackieren die folgenden mechanischen Eigenschaften auf:

  • Zugfestigkeit: Rm 240-280 N/mm2
  • Streckgrenze: Rp > 215 N/mm2
  • Bruchdehnung: A50 > 6 %.
The tape for rollform products has the following mechanical properties after painting:
  • Tensile strength: Rm 240-280 N / mm 2
  • Yield strength: Rp> 215 N / mm 2
  • Elongation at break: A50> 6%.

Bei der Herstellung des Bandes durch Stranggießen eines Walzbarrens, der Barrenvorwärmung im Temperaturbereich von 480 bis 610°C und des Warmwalzens im Temperaturbereich von 550°C bis 270°C wird das gewünschte Gefüge erzeugt. Das Gefüge des Bandes ist gekennzeichnet durch eine Anzahl der Gussphasen, auch grobe Ausscheidungen genannt, im Bereich von 2 bis 10 pro 1000 µm2 mit einer maximalen Größe von 40 µm und einer mittleren Länge von 2 bis 6 µm. Das Band weist ferner feine Ausscheidungen kleiner als etwa 1 µm aus, deren Anzahl im Bereich von 500 bis 1200 pro 1000 µm2 liegt.In the production of the strip by continuous casting of a rolling ingot, ingot preheating in the temperature range of 480 to 610 ° C and hot rolling in the temperature range of 550 ° C to 270 ° C, the desired structure is produced. The structure of the belt is characterized by a number of casting stages, also referred to as coarse precipitates, in the range of 2 to 10 per 1000 microns 2 with a maximum size of 40 μ m and an average length of 2-6 μ m. The belt further comprises fine precipitates of less than about 1 μ m, the number in the range of 500 to 1,200 per 1000 microns. 2

Schließlich weist das Band einen Lösungszustand auf, der durch Restwiderstände im Bereich von 1,2 bis 2,5 µohm cm gekennzeichnet ist. Die Restwiderstandsmessung erfolgt bei einer Heliumtemperatur von 4,2 K.Finally, the tape has a solution state characterized by residual resistances in the range of 1.2 to 2.5 μ ohm cm. The residual resistance measurement takes place at a helium temperature of 4.2 K.
