Description
Die Erfindung betrifft ein Verfahren gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a method according to the preamble of
Die DE 43 07 563 C2 zeigt ein Verfahren zum Herstellen eines Strukturbauteils. Dort werden ein Grundblech und ein Verstärkungsblech miteinander verbunden, das das Grundblech dann zumindest teilweise bedeckt und z.B. durch Punktschweißungen, Klebemittel oder Verschweißungen festgelegt ist. Diese Anordnung wird anschließend einem gemeinsamen Umformvorgang unterworfen, bei dem sie in eine gewünschte Form gebracht wird.DE 43 07 563 C2 shows a method for producing a structural component. There a base plate and a reinforcement plate are connected to each other, which is the The base plate is then at least partially covered and e.g. by spot welding, Adhesive or welding is set. This arrangement is then subjected to a common forming process in which they are shaped into a desired shape brought.
Bei dem Verfahren nach der DE 195 24 235 A1 (nächstliegender Stand der Technik) werden in dem Verstärkungsblech, wenn dieses als Tragteil für Bedienelemente genutzt werden soll, gezielte Lochungen oder Konturgestaltungen vorgesehen. Dadurch wird das jeweilige Verstärkungsblech auf seine Tragfunktion vorbereitet.In the method according to DE 195 24 235 A1 (closest prior art) in the reinforcing plate, if this should be used as a supporting part for controls, targeted holes or Contour designs provided. As a result, the respective reinforcement plate is on its Load function prepared.
Grundsätzlich ist bei derartigen Verfahren problematisch, daß das Grundblech und das Verstärkungsblech bei dem gemeinsamen Umformvorgang unterschiedlich gedehnt oder gestaucht werden. Dabei wird insbesondere das Verstärkungsblech bei einer Biegung, bei der es auf der Innenseite mit kleinerem Krümmungsradius sitzt, stärker gestaucht und bei einer Biegung, bei der es auf der Außenseite sitzt, stärker gedehnt, während das Grundblech entsprechend jeweils umgekehrt gedehnt bzw. gestaucht wird. Somit besteht allgemein die Neigung entweder zur Faltenbildung bei Stauchung oder zu einer Rißbildung bei Dehnung. In beiden Fällen werden die Materialeigenschaften des betreffenden Strukturbauteils verschlechtert.Basically, it is problematic in such methods that the base plate and the Reinforcement plate in the common forming process differently stretched or be upset. In this case, the reinforcement plate in particular during a bend, where it sits on the inside with a smaller radius of curvature, more compressed and on a bend where it sits on the outside, stretched more while the Base plate is respectively stretched or compressed in reverse. So there is generally the tendency to either form wrinkles during compression or to Cracking when stretched. In both cases, the material properties of the relevant structural component deteriorated.
Die Festigkeit des Strukturbauteils kann dabei in der Regel nur durch Verwendung einer höheren Materialstärke gewährleistet werden, da bei Verwendung dünnerer Bleche die Gefahr einer Rißbildung zu groß und auch die Beeinträchtigung durch die Faltenbildung zu stark ist. Hierdurch werden jedoch wiederum das Gesamtgewicht und die Materialkosten erhöht.The strength of the structural component can usually only be achieved by using a higher material thickness can be guaranteed, since when using thin sheets Risk of crack formation too great and also the impairment due to the formation of folds is too strong. However, this in turn increases the total weight and the Material costs increased.
Diese Problematik besteht auch im Falle des Verfahrens nach der zitierten DE 195 24 235 A1, die mit Befestigungslöchern für Bedienelemente in dem Verstärkungsblech arbeitet. Diese Befestigungslöcher, die erst nach dem Umformvorgang mehr oder weniger vollkommen durch die Bedienelemente verschlossen werden, sind in ihrer Lage, Größe und Ausbildung vorgegeben durch die Bedienelemente, nicht aber durch die ausführlich beschriebene Problematik einer möglichen Falten- oder Rißbildung. This problem also exists in the case of the method according to DE 195 24 cited 235 A1, with mounting holes for controls in the reinforcement plate is working. These mounting holes that only after the forming process more or are less completely closed by the controls, are able to Size and training specified by the controls, but not by the detailed problems of possible wrinkles or cracks.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren zur Herstellung eines Strukturbauteiles für Kraftfahrzeuge derart weiterzubilden, daß die Faltenbildung und Rißbildung in der Platine beim Umformvorgang gering gehalten werden und dennoch ein niedriges Gesamtgewicht eingehalten wird.The invention is therefore based on the object a method for producing a structural component for motor vehicles develop in such a way that the formation of folds and cracks in the board when Forming process can be kept low and still a low total weight is observed.
Diese Aufgabe wird durch ein Verfahren nach Anspruch 1
gelöst. Die Unteransprüche beschreiben bevorzugte
Weiterbildungen.This object is achieved by a method according to
Da vor dem Umformen durch in dem Verstärkungsblech vorgesehene Durchgangsöffnungen materialfreie Bereiche gebildet sind, steht der Materialdehnung bzw. -ausdehnung des Verstärkungsbleches während des Umformvorganges ein entsprechender materialfreier Raum zur Verfügung. Dies hat zum einen zur Folge, daß die ursprünglich materialfreien Bereiche durch das Umformen verformt, z.B. vergrößert, verkleinert oder sogar verschlossen werden können. Zum anderen können stegartige Bereiche des Verstärkungsblechs zwischen den Durchgangsöffnungen sich stärker als das Material des Grundblechs dehnen und somit die unsymmetrischen Beanspruchungen während des Umformvorgangs ausgleichen. Somit kann auch bei relativ geringen Blechdicken die Faltenbildung des Verstärkungsbleches und eine mögliche Rißbildung verringert bzw. vermieden werden.As before forming through through openings provided in the reinforcement plate material-free areas are formed, the material expansion or expansion of the Reinforcing sheet a corresponding material-free during the forming process Space available. On the one hand, this has the consequence that the originally material-free Areas deformed by forming, e.g. enlarged, reduced or even closed can be. On the other hand, web-like areas of the reinforcement plate can between the through openings stretch more than the material of the base plate and thus the asymmetrical stresses during the forming process compensate. Thus, the wrinkling of the Reinforcing sheet and possible cracking can be reduced or avoided.

Die Fig. 1 und 2 zeigen ein Verstärkungsblech 1a, das mehrere Durchgangslöcher 2a
aufweist und als Lochblech ausgeführt ist. Die Durchgangslöcher 2a sind hier kreisförmig
ausgebildet. 1 and 2 show a reinforcing
Fig. 2 zeigt ein Verstärkungsblech 1a, das mehrere Durchgangslöcher 2a aufweist, die
kreuzförmig ausgebildet sind.Fig. 2 shows a reinforcing
Die Durchgangslöcher 2 können auch andere geometrische Formen aufweisen,
beispielsweise schlitzförmig oder länglich sein.The through
Zwischen den Durchgangslöchern 2a bzw 2b sind stegartige Bereiche 3a bzw 3b
ausgebildet, die entsprechend der geometrischen Anordnung der Durchgangslöcher jeweils
parallel und unter einem Winkel α bzw β verlaufen, wobei α bei in Fig. 1 der gezeigten
symmetrischen Anordnung 60 Grad und β bei der in Fig. 2 gezeigten Anordnung 90 Grad
beträgt.Between the through
Das in den Fig. 1 und 2 dargestellte Verstärkungsblech 1 kann in verschiedenen Bereichen
auch eine unterschiedliche, aber in den jeweiligen Bereichen dann bestimmte Materialdicke
aufweisen, so daß beim Umformen der Verstärkungsplatte 1 zur Erzeugung des
Strukturbauteiles in diesen Bereichen dann ein optimaler Materialfluß bzw. eine optimale
Materialdehnung erfolgen kann. Durch bestimmte Stähle bzw. Materialien kann dieses
unterstützt werden, insbesondere wenn das Grundblech sowie das Verstärkungsblech 1
jeweils eine bestimmte Gefügestruktur aufweisen.The
Das in den Fig. 1 und 2 gezeigte Verstärkungsblech 1a,b wird nun mit dem Grundblech 4
zumindest teilweise verbunden. Dies kann beispielsweise durch eine entsprechende
Punktschweißtechnik, aber auch durch eine besondere Fügetechnik oder Klebetechnik bzw.
Kombinationen dieser Verfahren erfolgen. Von Vorteil ist, wenn im Bereich zwischen dem
Grundblech und dem Verstärkungsblech 1 entsprechende Korrosionsschutzmaßnahmen
durchgeführt werden. In Abhängigkeit davon, wo das erzeugte Strukturbauteil an einem
Kraftfahrzeug eingesetzt wird, kann das Strukturbauteil auch ein relativ großes Grundblech
und hierauf angeordnet mehrere Verstärkungsbleche 1 aufweisen.The
Anschließend wird die aus Grundblech 4 und Verstärkungsblech 1 gebildete Platine einem
Umformvorgang, z.B. einem Tiefziehvorgang unterzogen. Hierbei werden die beiden Bleche
gemeinsam umgeformt. Dabei werden die Löcher 2a, b in dem Verstärkungsblech
entsprechend den lokalen Verformungen verformt, z.B. vergrößert oder verkleinert oder
unsymmetrisch verändert. Somit können die Belastungen des Verstärkungsblech durch eine
Verformung der Löcher aufgenommen werden, so daß ein Materialfluß über eine größere
Fläche und eine Rißbildung auch bei dünnen Verstärkungsblechen vermieden wird.Subsequently, the circuit board formed from
Weiterhin können die stegartigen Bereiche 3a,b zwischen den Durchgangslöchern im
Verstärkungsblech stärker gedehnt werden als das Material der Grundplatte. Somit kann
eine unsymmetrische Verformung der Platine von dem Verstärkungsblech aufgenommen
werden, indem die Löcher verformt werden und die stegartigen Bereiche -ggf in
unterschiedlichen Richtungen unterschiedlich stark - gedehnt werden.Furthermore, the web-
Diese Materialdehnung bzw. -ausdehnung ist unter anderem abhängig von der Geometrie

of the through
Im Ergebnis ist durch das beschriebene Verfahren eine plastische Verformung des
