Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines Strukturbauteils für den Fahrzeugbau.The invention relates to a method for producing a structural component for vehicle construction.
Strukturbauteile für den Fahrzeugbau sind beispielsweise Stoßfänger, Seitenaufprallträger oder Türsäulen. Zur Herstellung der meisten dieser Strukturbauteile hat sich ein mit Aluminium beschichteter Borstahl als vorteilhaft erwiesen. Hierbei werden die Strukturbauteile im erwärmten Zustand unmittelbar aus einer Platine in die Endform gebracht.Structural components for vehicle construction are, for example, bumpers, side impact beams or door pillars. To manufacture most of these structural components a boron steel coated with aluminum has proven to be advantageous proved. Here, the structural components are heated immediately brought from a board into the final shape.
Es gibt indessen mit Aluminium beschichtete Strukturbauteile aus Borstahl komplizierter Formgebung, die nicht in einem einzigen Arbeitsgang in die Endform gebracht werden können. In einem solchen Fall müssten die Strukturbauteile in zwei oder mehr Werkzeugen nacheinander zunächst kalt umgeformt werden. Dies hätte zur Folge, dass die Aluminiumbeschichtung während des Formvorgangs reißt und das Grundmaterial freigelegt wird. Die schützende Beschichtung wäre zerstört.There are, however, structural components made of boron steel coated with aluminum complicated shape, which is not in a single operation in the final shape can be brought. In such a case, the structural components would have to cold formed in two or more tools one after the other become. This would have the consequence that the aluminum coating during the Molding process tears and the base material is exposed. The protective Coating would be destroyed.
Der Erfindung liegt - ausgehend vom Stand der Technik - die Aufgabe zugrunde, ein Verfahren vorzuschlagen, mit welchem auch komplizierte Konfigurationen eines Strukturbauteils aus mit Aluminium beschichteten Borstählen für den Fahrzeugbau bereit gestellt werden können.The object of the invention is based on the prior art to propose a method with which even complicated configurations of a structural component made of boron steel coated with aluminum can be made available for vehicle construction.
Diese Aufgabe wird mit den in den Patentansprüchen 1 bis 3 angegebenen Merkmalen gelöst.This object is achieved with those specified in claims 1 to 3 Features resolved.
Eine Lösung sieht vor, dass zunächst unter Umgebungstemperatur, das heißt Raumtemperatur, aus einer beispielsweise von einem Coil abgetrennten Platine aus Borstahl ein Strukturbauteil je nach seiner Komplexität in einem Werkzeug oder in mehreren Werkzeugen nacheinander bis in die Nähe seiner Endform vorkonfiguriert wird. Diese Vorverformung kann problemlos erfolgen, da die Platine aus Borstahl nicht beschichtet ist.One solution provides that initially under ambient temperature, that is Room temperature, for example from a board separated from a coil A structural component made of boron steel depending on its complexity in one tool or in several tools one after the other up to the vicinity of its final shape is preconfigured. This pre-deformation can be carried out without any problems since the Boron steel board is not coated.
Hat das Strukturbauteil annähernd seine Endform erreicht, wird es bei einer Temperatur von ca. 650 °C mit Aluminium oder einer Aluminiumlegierung beschichtet. Dies kann beispielsweise im Tauchverfahren durchgeführt werden.If the structural component has almost reached its final shape, it will be at one Temperature of approx. 650 ° C coated with aluminum or an aluminum alloy. This can be done, for example, in the immersion process.
Nach der Beschichtung mit Aluminium oder einer Aluminiumlegierung wird das Strukturbauteil auf eine Temperatur oberhalb der oberen Umwandlungslinie im Z-T-U-Schaubild gebracht, dann in einem Werkzeug in die Endform konfiguriert und dabei gleichzeitig gehärtet. Die Erwärmungstemperatur beträgt etwa 930 °C.After coating with aluminum or an aluminum alloy, it will Structural component to a temperature above the upper conversion line in the Z-T-U diagram brought, then configured into the final shape in one tool and hardened at the same time. The heating temperature is approximately 930 ° C.
Eine zweite Lösungsvariante der Aufgabe sieht vor, dass das, wie vorstehend erläutert, vorkonfigurierte Strukturbauteil auf eine Temperatur oberhalb der oberen Umwandlungslinie im Z-T-U-Schaubild (z.B. 930 °C) gebracht, dann in einer Schmelze bei einer Temperatur ebenfalls oberhalb der oberen Umwandlungslinie im Z-T-U-Schaubild mit Aluminium oder einer Aluminiumle-gierung beschichtet und danach in einem Werkzeug bei gleichzeitiger Härtung in die Endform konfiguriert wird.A second solution variant of the task provides that as above explained, preconfigured structural component to a temperature above the upper conversion line in the Z-T-U diagram (e.g. 930 ° C), then in a melt at a temperature also above the upper conversion line in the Z-T-U diagram with aluminum or an aluminum alloy coated and then in one tool with simultaneous hardening in the Final shape is configured.
Des Weiteren ist es gemäß einer dritten Lösungsvariante möglich, ein vorgeformtes Strukturbauteil in der Aluminiumschmelze selbst auf eine Temperatur oberhalb der oberen Umwandlungslinie im Z-T-U-Schaubild zu bringen (etwa 930 °C) und dann in einem Werkzeug unter gleichzeitiger Härtung in die Endform zu konfigurieren.Furthermore, according to a third solution variant, it is possible to use a preformed one Structural component in the aluminum melt itself at a temperature above the upper conversion line in the Z-T-U diagram (approx 930 ° C) and then in a tool with simultaneous hardening into the final shape to configure.
Der besondere Vorteil, welcher mit den erfindungsgemäßen Maßnahmen verbunden ist, liegt darin, dass jetzt auch Strukturbauteile mit komplizierten Endformen ohne weiteres aus mit Aluminium oder einer Aluminiumlegierung beschichtetem Borstahl hergestellt werden können, ohne dass mit Beschädigungen der Beschichtung während des Umformvorgangs gerechnet werden muss.The particular advantage associated with the measures according to the invention is that structural components with complicated end shapes are now available readily made of coated with aluminum or an aluminum alloy Boron steel can be made without causing damage the coating must be expected during the forming process.
Außerdem lässt die Erfindung es bei allen drei Lösungsvarianten zu, bei Bedarf an die Härtung noch einen Vergütungsvorgang anzuschließen.In addition, the invention allows for all three solution variants, if necessary to connect a hardening process to the hardening.
