Description

Wölbstrukturiertes Karosseriebauteil und Verfahren zu seiner Herstellung Vault-structured body component and method for its production
Die Erfindung betrifft ein Bauteil und ein Verfahren zu seiner Herstellung nach dem Oberbegriff der Ansprüche 1 und 7.The invention relates to a component and a method for its production according to the preamble of claims 1 and 7.
Es ist bekannt, wölbstrukturierte Bleche im Automobilbereich zu verwenden. Unter wölbstrukturiertem Blech wird hierbei ein Blech verstanden, das mit einer versteifenden Makrostruktur versehen ist, welche mit Hilfe eines Beulverfahrens in das Blech eingebracht wird; derartige Bleche sind beispielsweise in der DE 44 37 986 AI beschrieben. Im Gegensatz zu der Wirkung klassischer Umformverfahren (wie z.B. Walzprägen oder Hydroforming) , bei denen während des Umformens eine Plastifizierung des Blechs stattfindet, wird das Blech beim Wölbstrukturieren lediglich lokal gefaltet; dies ist verbunden mit einer nur unwesentlichen Oberflächenvergrößerung des Materials. Die Beulverformung erfolgt in einem Durchlaufverfahren, so das gesamte Materialbahnen (bzw. bandartige Bereiche von ihnen) mit der Wölbstruktur versehen werden. Die Wölbstrukturierung hat eine Erhöhung der Biegesteifigkeit zur Folge. Im Gegensatz zu unstrukturierten Blechen kann daher die Blechdicke ohne Steifigkeitseinbussen wesentlich geringer gewählt werden. Zur Herstellung steifigkeitserhöhter Karosseriebauteile werden aus diesen Materialbahnen Platinenzuschnitte gefertigt, aus denen dann durch weitere Prozessschritte die gewünschten Bauteile hergestellt werden. Die weitere Fertigung der Bauteile erfolgt durch mehrere, voneinander entkoppelte Prozessschritte :It is known to use arch-structured sheets in the automotive sector. Arched sheet metal is understood here to mean a sheet which is provided with a stiffening macrostructure which is introduced into the sheet by means of a buckling process; such sheets are described for example in DE 44 37 986 AI. In contrast to the effect of classic forming processes (such as roll embossing or hydroforming), in which the sheet is plasticized during the forming process, the sheet is only folded locally during the vault structuring; this is associated with an insignificant increase in the surface area of the material. The bulge deformation takes place in a continuous process, so that the entire material webs (or band-like areas of them) are provided with the arch structure. The arching structure increases the bending stiffness. In contrast to unstructured sheets, the sheet thickness can therefore be selected to be significantly smaller without sacrificing rigidity. In order to produce body components with increased stiffness, blank blanks are made from these material webs, from which the desired components are then produced in further process steps. The further production of the components takes place through several, decoupled process steps:
Der Platinenzuschnitt wird z.B. in einer ersten Umformstufe tiefgezogen, anschließend wird plattiert. Darauf folgt eine zweite Ziehstufe und weitere separate Prozesse zum Ausklinken, Abkanten, Abstellen von z.B. Flanschen und Verbinden von Flanschen sowie Bauteilen.The blank is e.g. deep-drawn in a first forming step, followed by plating. This is followed by a second drawing stage and other separate processes for notching, folding, and parking e.g. Flanges and connecting flanges and components.
Weiterhin ist bekannt, Karosseriebauteile für Kraftfahrzeuge durch kontinuierlichen Prozessablauf, insbesondere durch Rollprofilieren, herzustellen.It is also known to manufacture body components for motor vehicles by means of a continuous process, in particular by roll profiling.
In der DE 199 57 910 AI ist die Herstellung eines Formbauteils ungleicher Dicke beschrieben, bei dem durch Rollprofilieren Bleche durch mechanisches Fügen verbunden werden. Durch das Einprägen von Sicken oder Kanten in die Bleche während der Rollprofilierung werden die Bleche positioniert .DE 199 57 910 AI describes the production of a molded component of unequal thickness, in which sheets are connected by mechanical profiling by roll profiling. The sheets are positioned by embossing beads or edges in the sheets during roll profiling.
Die Herstellung eines länglichen Hohlkörpers für Karosseriekomponenten mittels Rollprofilieren ist aus der DE 101 41 503 Cl bekannt. Danach wird der die Materialreserve bildende Flansch ohne zusätzlichen Herstellungsaufwand bei der Herstellung eines zu einem Hohlkörper innenhochdruckumzuformenden Grundkörpers durch Rollprofilieren eines Blechzuschnitts umgeformt.The production of an elongated hollow body for body components by means of roll profiling is known from DE 101 41 503 Cl. Thereafter, the flange forming the material reserve is reshaped by roll profiling a sheet metal blank without additional manufacturing outlay in the production of a base body to be formed into a hollow body with internal high pressure.
Die bei herkömmlicher Vorgehensweise erforderlichen Prozesse (z.B. Tiefziehen, Abkanten und Plattieren) führen zu Defekten, beispielsweise zu Froscheffekten, die lediglich durch aufwändiges Einbringen von Nebenformelementen zu kompensieren sind.The processes required in the conventional procedure (e.g. deep drawing, chamfering and plating) lead to defects, for example frog effects, which can only be compensated for by laboriously inserting secondary form elements.
Aufgabe der Erfindung ist es, ein wölbstrukturiertes Karosseriebauteil anzugeben, das seine hohe Formsteifigkeit auch nach der Weiterverarbeitung beibehält. Weiterhin liegt der Erfindung die Aufgabe zugrunde, ein schnelleres und preisgünstiges Verfahren zur Herstellung des Bauteils anzugeben.The object of the invention is to provide a domed body component that maintains its high dimensional stability even after further processing. Still lies The invention has for its object to provide a faster and less expensive method for manufacturing the component.
Die Erfindung ist in den Ansprüchen 1 und 7 beschrieben. Vorteilhafte Ausgestaltungen sind den Unteransprüchen zu entnehmen.The invention is described in claims 1 and 7. Advantageous configurations can be found in the subclaims.
Gemäß der Erfindung werden wölbstrukturierte Karosseriebauteile derart hergestellt, dass in einem ersten Schritt die Wölbstrukturierung des Materials und in einem zweiten Schritt die Herstellung des Karosseriebauteils durchgeführt wird, wobei die Herstellung des Karosseriebauteils durch Rollprofilieren erfolgt. Die wölbstrukturierten Materialien sind beispielsweise Blechplatinen oder faserverstärkte Kunststoffe, die beschichtet sein können.According to the invention, vault-structured body components are produced in such a way that the vault structuring of the material is carried out in a first step and the body component is produced in a second step, the body component being produced by roll profiling. The arch-structured materials are, for example, sheet metal blanks or fiber-reinforced plastics, which can be coated.
Bei der Herstellung des Karosseriebauteils werden zumindest die Prozesse Plattieren, Umformen und Zuschneiden des wölbstrukturierten Materials in einem Rollprofilierungs- verfahren durchgeführt. Durch plattieren werden beispielsweise Füge-Flansche, Sicken und/oder Kanten hergestellt und durch Umformen werden z.B. Füge-Flansche abgestellt .In the manufacture of the body component, at least the processes of plating, forming and cutting the arch-structured material are carried out in a roll profiling process. For example, joining flanges, beads and / or edges are produced by plating, and reshaping e.g. Joining flanges turned off.
Das wölbstrukturierte Material wird beispielsweise mit nahezu wölbstrukturfreien Anschlusszonen versehen, die im Rollprofilierungsverfahren plattiert werden.The arch-structured material is provided, for example, with almost arch-free connection zones, which are clad in the roll profiling process.
Anschließend an die Strukturierungs- und Formprozesse wird das bearbeitete Material in vorgegebene Längen zugeschnitten.Following the structuring and molding processes, the processed material is cut to specified lengths.
Vorteilhafterweise wird das Material für die Wölbstrukturierung und Rollprofilierung von einem Coil zugeführt . Mit dem erfindungsgemäßen Verfahren wird ein Karosseriebauteil hergestellt, das eine durch Rollprofilieren eingebrachte Anschlusszone aufweist, in der das Material näherungsweise wölbstrukturfrei ist. Die Anschlusszonen weisen z.B. Sicken, Flansche und/oder Kanten auf.The material for the arch structuring and roll profiling is advantageously fed from a coil. With the method according to the invention, a body component is produced which has a connection zone introduced by roll profiling, in which the material is approximately free from a vault structure. The connection zones have beads, flanges and / or edges, for example.
Auf dem Karosseriebauteil können die Anschlusszonen randseitig oder im Bauteilinneren angeordnet sein.The connection zones can be arranged on the edge of the body or inside the component on the body component.
Die den wölbstrukturierten Versteifungszonen benachbarten Anschlusszonen auf den Karosseriebauteilen haben den Vorteil, dass die Vielzahl von Karosseriebauteile (Bodenanlagen, Beplankungen, Trennwände und Träger) mit Hilfe herkömmlicher Verfahren einfach verbunden oder an Folgebauteile angebunden werden können. Dies ermöglicht einen breiten, kostengünstigen Großserieneinsatz .The connection zones on the body components adjacent to the arched stiffening zones have the advantage that the large number of body components (floor systems, planking, partitions and beams) can be easily connected using conventional methods or connected to subsequent components. This enables a wide, cost-effective use in large series.
Das erfindungsgemäße Verfahren hat den Vorteil, dass das wölbstrukturierte Karosseriebauteil seine hohe Formsteifigkeit auch nach der Weiterverarbeitung durch den kontinuierlichen Ablauf des Rollprofilierungsprozesses beibehält. Weiterhin ist von Vorteil, dass durch das Rollprofilierungsverfahren die Bauteilherstellzeiten verringert werden und Werkzeugkosten, insbesondere bei den Umformungsprozessen eingespart werden. Dadurch dass ein kontinuierlicher Prozess an einer Fertigungsstätte stattfindet, verringern sich auch die Handling- und Logistikkosten.The method according to the invention has the advantage that the vault-structured body component maintains its high dimensional stability even after further processing by the continuous process of the roll profiling process. It is also advantageous that the roll profiling process reduces the component manufacturing times and saves tool costs, particularly in the forming processes. The fact that a continuous process takes place at a production facility also reduces handling and logistics costs.
