Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines geformten Karosseriebauteils für eine Fahrzeugkarosserie eines Kraftfahrzeugs aus einem Tailored Blank gemäß Oberbegriff des Patentanspruchs 1.The invention relates to a method for producing a shaped body component for a vehicle body of a motor vehicle from a tailored blank according to the preamble of patent claim 1.
Aus dem Stand der Technik sind sogenannte Tailored Blanks mit unterschiedlichen Materialstärken oder unterschiedlichen Materialien bekannt. Unter dem Begriff „Tailored Blank” werden Bleche mit unterschiedlicher Materialstärke aus dem gleichen Material oder auch aus unterschiedlichen Materialien mit gleicher oder unterschiedlicher Dicke bezeichnet, die zu einem Halbzeug verbunden werden. Dieses Halbzeug wird anschließend zu einem Bauteil, bspw. zu einem Karosseriebauteil derart geformt, dass sich im fertigen Bauteil bspw. Zonen geringerer Stärke oder geringerer Festigkeit in den schwächer belasteten Bereichen und Zonen größerer Stärke oder höherer Festigkeit in den stärker belasteten Bereichen des fertigen Bauteils befinden.So-called tailored blanks with different material thicknesses or different materials are known from the prior art. The term "tailored blank" refers to sheets of different material thickness of the same material or of different materials with the same or different thickness, which are joined to form a semi-finished product. This semi-finished product is then formed into a component, eg. To a body component such that in the finished component, for example, zones of lesser strength or lower strength in the weaker loaded areas and zones greater strength or higher strength in the more heavily loaded areas of the finished component ,
Aus der
Aufgabe der Erfindung ist es, demgegenüber ein verbessertes Verfahren der eingangs genannten Art anzugeben, mit dem gewichts- und crashoptimierte Karosseriebauteile herstellbar sind.The object of the invention is to provide an improved method of the type mentioned, with the weight and crash-optimized body parts can be produced.
Diese Aufgabe wird gelöst durch ein Verfahren mit den Merkmalen des Patentanspruchs 1.This object is achieved by a method having the features of patent claim 1.
Ein solches Verfahren zur Herstellung eines geformten Karosseriebauteils für eine Fahrzeugkarosserie eines Kraftfahrzeugs aus einem Tailored Blank, bei dem das Tailored Blank als Halbzeug mittels eines Umformwerkzeugs geformt wird, zeichnet sich erfindungsgemäß dadurch aus, dass das Halbzeug aus zumindest zwei Aluminium-Blechteile in unterschiedlichen Dicken und/oder unterschiedlichen Legierungszusammensetzungen gebildet wird, wobei die Aluminium-Blechteile vor dem Formen mittels eines Schweißverfahrens unter Bildung einer Stumpfstoß- oder Überlappverbindung fest miteinander verbunden werden.Such a method for producing a shaped body component for a vehicle body of a motor vehicle from a tailored blank, in which the tailored blank is formed as a semi-finished by means of a forming tool, according to the invention is characterized in that the semifinished product from at least two aluminum sheet metal parts in different thicknesses and or different alloy compositions is formed, wherein the aluminum sheet metal parts before forming by means of a welding process to form a butt joint or lap joint are firmly bonded together.
Als Schweißverfahren wird dabei vorzugsweise das Reibrührschweißen verwendet.The welding method used here is preferably friction stir welding.
Mit einem solchen erfindungsgemäßen Verfahren lassen sich in einem aus Aluminium hergestellten Karosseriebauteil Aluminiumlegierungen unterschiedlichster Festigkeitsklassen und Blechdicken kombinieren, um somit alle Möglichkeiten hinsichtlich einer Gewichts- und Crashoptimierung auszuschöpfen.With such a method according to the invention aluminum alloys of different strength classes and sheet thicknesses can be combined in a body component made of aluminum, in order thus to exhaust all possibilities with regard to weight and crash optimization.
Das bedeutet auch, dass zur Erfüllung von Crash-Anforderungen solche Aluminiumlegierungen kombiniert werden können, um eine hohe Festigkeit und gleichzeitig eine ausreichende Duktilität zu erzielen.This also means that to meet crash requirements such aluminum alloys can be combined to achieve high strength and sufficient ductility at the same time.
In einer Ausgestaltung der Erfindung besteht das Halbzeug aus einem Aluminium-Blechteil mit einer AA6xxx-Legierung und einem Aluminium-Blechteil mit einer AA7xxx-Legierung. Verglichen mit den AA6xxx-Legierungen können die AA7xxx-Legierungen eine beträchtlich höhere mechanische Festigkeit aufweisen. So wird gemäß einer Weiterbildung der Erfindung ein Blechteil mit einer AA6016-Legierung entweder mit einem Blechteil aus einer AA7021-Legierung oder einer AA7081-Legierung zu Herstellung des Halbzeugs kombiniert. Die verwendete Nomenklatur zur Bezeichnung dieser Aluminiumlegierungen bezieht sich auf das System der AA (Aluminium Association).In one embodiment of the invention, the semifinished product consists of an aluminum sheet metal part with an AA6xxx alloy and an aluminum sheet metal part with an AA7xxx alloy. Compared to the AA6xxx alloys, the AA7xxx alloys can have considerably higher mechanical strength. Thus, according to a development of the invention, a sheet metal part is combined with an AA6016 alloy either with a sheet metal part made of an AA7021 alloy or an AA7081 alloy to produce the semi-finished product. The nomenclature used to refer to these aluminum alloys refers to the AA (Aluminum Association) system.
Vorzugweise können für diese Kombinationen Aluminium-Blechteile mit identischer Dicke verwendet werden.Preferably, aluminum sheet metal parts of identical thickness can be used for these combinations.
Besonders vorteilhaft lässt sich das erfindungsgemäße Verfahren zur Herstellung einer Fahrzeugkarosserie-Säule, vorzugsweise einer A- oder B-Säule oder eines Fahrzeugkarosserie-Trägers verwenden.The method according to the invention can be used particularly advantageously for producing a vehicle body pillar, preferably an A or B pillar or a vehicle body carrier.
