Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines Verbundbauteils aus einem Metallbauteil und einem Kunststoffbauteil gemäß Oberbegriff des Patentanspruchs 1. Ferner betrifft die Erfindung ein mit dem erfindungsgemäßen Verfahren hergestelltes Verbundbauteil.The invention relates to a method for producing a composite component from a metal component and a plastic component according to the preamble of
Ein gattungsbildendes Verfahren zur Herstellung eines Verbundbauteils aus einem Metallbauteil und einem Kunststoffbauteil ist aus der
Die
Die
Im Fahrzeugbau werden aus Gewichts- und Belastbarkeitsgründen vermehrt faserverstärkte Kunststoffe eingesetzt, insbesondere für Karosserieteile. Solche Karosserieteile stellen bspw. hochbelastete faserverstärkte Profile dar, die in eine metallische Umgebung integriert werden müssen. Die bei herkömmlichen Metallkarosserieteilen zum Einsatz kommenden Anbringungsarten bzw. Verbindungstechniken sind für die Anbindung solcher hochbelastete faserverstärkte Profile nicht ohne weiteres anwendbar.In vehicle construction, fiber-reinforced plastics are increasingly being used for weight and load-bearing purposes, in particular for body parts. Such body parts represent, for example, highly stressed fiber-reinforced profiles, which must be integrated into a metallic environment. The types of attachment or joining techniques used in conventional metal body parts are not readily applicable to the attachment of such highly stressed fiber reinforced profiles.
So ist es bekannt, Einlegeteile als Lasteinleitungselemente aus Metall, wie bspw. Gewindebolzen in faserverstärkte Kunststoffe zu integrieren. Diese dienen als Verbindungsschnittstellen für Schraubverbindungen mit anderen Bauelementen, wie bspw. Metallbauteilen. Solche Einlegeteile weisen häufig eine komplexe Oberflächenstruktur auf, um eine zufriedenstellende Festigkeit der Metall-Kunststoff-Verbindung zu erreichen.Thus, it is known to integrate inserts as load introduction elements made of metal, such as, threaded bolts in fiber-reinforced plastics. These serve as connection interfaces for screw connections with other components, such as, for example, metal components. Such inserts often have a complex surface structure in order to achieve a satisfactory strength of the metal-plastic compound.
Solche Lasteinleitungselemente werden in faserverstärkte Kunststoffbauteile in der Regel erst nach der Formgebung des Kunststoffbauteils eingebracht, wobei hierzu aufwändige Prozesse, wie Bohren, Fräsen, Einpressen, Einkleben usw. erforderlich sind. Um bspw. eine Hülse aus Metall in ein solches faserverstärktes Kunststoffbauteil einzubringen, wird das Kunststoffbauteil nach dessen eigentlichen Herstellungsprozess gebohrt und anschließend die Hülse eingepresst oder eingeklebt. Solche Verfahren sind aufwändig und teuer und daher nicht wirtschaftlich durchführbar, insbesondere auch wegen der langen Taktzeiten.Such load introduction elements are usually introduced into fiber-reinforced plastic components only after the shaping of the plastic component, for which complex processes such as drilling, milling, press-fitting, gluing, etc. are required. In order, for example, to introduce a sleeve of metal into such a fiber-reinforced plastic component, the plastic component is drilled after its actual manufacturing process and then the sleeve is pressed or glued. Such methods are complex and expensive and therefore not economically feasible, especially because of the long cycle times.
Bei zusätzlich zu einem hülsenförmigen Metalleinlegen in ein Kunststoffbauteil eingebrachten Verstärkungen, bspw. als Edelstahlblech ist das Einbringen einer Bohrung ohne Schädigung der Kunststoffstruktur durch die starke Erwärmung des Edelstahlblechs nicht möglich und kann zur Delamination der Faserlagen der Kunststoffstruktur führen. Außerdem besteht kein Stoffschluss zwischen dem hülsenförmigen Metalleinleger und der Verstärkung.In addition to a sleeve-shaped metal inserting in a plastic component introduced reinforcements, for example. As stainless steel sheet, the introduction of a hole without damaging the plastic structure by the strong heating of the stainless steel sheet is not possible and can lead to delamination of the fiber layers of the plastic structure. In addition, there is no material connection between the sleeve-shaped metal insert and the reinforcement.
Schließlich ist aus der
Ausgehend von diesem Stand der Technik ist es Aufgabe der Erfindung ein Verfahren der eingangs genannten Art zu schaffen, mit welchem ein Verbundbauteil aus einem Metallbauteil und einem Kunststoffbauteil erzeugt wird, bei welchem das Metallbauteil als metallischer Einleger zur Verwendung als Verbindungsschnittstelle geeignet ist und die Verbindung zwischen dem Metallbauteil und dem Kunststoffbauteil eine hohe mechanische Festigkeit, Belastbarkeit und Dauerhaftigkeit aufweist.Based on this prior art, it is an object of the invention to provide a method of the type mentioned above, with which a composite component of a metal component and a plastic component is produced, in which the metal component is suitable as a metallic insert for use as a connection interface and the connection between the metal component and the plastic component has a high mechanical strength, resilience and durability.
Diese Aufgabe wird gelöst durch ein Verfahren mit den Merkmalen des Patentanspruchs 1.This object is achieved by a method having the features of
Eine solches Verfahren zur Herstellung eines Verbundbauteils aus einem Metallbauteil und einem Kunststoffbauteil, bei dem das Metallbauteil mindestens eine Öffnung mit einem Stanzrand aufweist und mittels des Stanzrandes beim Fügen des Kunststoffbauteils mit dem Metallbauteil das Kunststoffbauteil durchdrungen wird, zeichnet sich erfindungsgemäß dadurch aus, dass
- – das Metallbauteil mit zwei beabstandeten und jeweils eine Öffnung aufweisende Flachabschnitten hergestellt ist, wobei die Öffnungen miteinander fluchten und jeweils randseitige und in entgegengesetzte Richtungen gerichtete Stanzränder aufweisen,
- – zur Aufnahme des Metallbauteils das Kunststoffbauteil als thermoplastisches Hohlprofil hergestellt ist, und
- – das Hohlprofil mit dem in dasselbe eingelegte Metallbauteil mittels eines Umformprozesses im Bereich der Öffnungen des Metallbauteils senkrecht zu den Flachabschnitten derart verpresst wird, dass durch die Stanzränder eine mit den Öffnungen fluchtende Durchgangsöffnung aus der Wandung des Hohlprofils ausgestanzt wird.
- - The metal component is made with two spaced and each having an opening flat portions, wherein the openings are aligned with each other and each have edge-side and directed in opposite directions punch edges,
- - For receiving the metal component, the plastic component is made as a thermoplastic hollow profile, and
- - The hollow profile is pressed with the metal component inserted in the same by means of a forming process in the region of the openings of the metal component perpendicular to the flat portions such that punched by the punching edges aligned with the openings through opening from the wall of the hollow profile.
Diese Erfindung schafft ein Verbundbauteil, bei welchem das Metallbauteil gleichzeitig die Funktion eines metallischen Einlegers als auch die Funktion eines Stanzelementes bei der Erzeugung einer Durchgangsöffnung während des Umformprozesses durch Verpressen des Hohlprofils mit dem Metallbauteil übernimmt. Das erfindungsgemäße Verfahren ist besonders kostengünstig, da mit dem Umformprozess zur Formgebung des Verbundbauteils gleichzeitig die Durchgangsöffnung erzeugt als auch die von den Flachabschnitten des Metallbauteils gebildeten metallischen Einlegern eingebracht werden.This invention provides a composite component in which the metal component simultaneously performs the function of a metallic insert as well as the function of a punching element in the production of a through hole during the forming process by pressing the hollow profile with the metal component. The method according to the invention is particularly cost-effective, since the through-opening is generated simultaneously with the forming process for shaping the composite component, and the metallic inserts formed by the flat sections of the metal component are introduced as well.
Der besondere Vorteil dieses Verfahren liegt darin, dass das Metallbauteil als Einleger prozessintegrativ in das Hohlprofil eingebracht wird, d. h. dass mit dem Umformen des Hohlprofils, welches vorzugsweise als faserverstärktes Profil ausgebildet ist, gleichzeitig auch das Metallbauteil umgeformt und damit in dieses Hohlprofil integriert wird, ohne dass eine Nachbearbeitung erforderlich wäre. Dadurch kann dieses Verbundbauteil, insbesondere als Lasteinleitungselement kostengünstig, also wirtschaftlich mit kurzen Standzeiten hergestellt werden.The particular advantage of this method is that the metal component is introduced as an insert process integrally into the hollow profile, d. H. that with the forming of the hollow profile, which is preferably formed as a fiber-reinforced profile, at the same time, the metal component is formed and thus integrated into this hollow profile, without a post-processing would be required. As a result, this composite component, in particular as a load introduction element cost, so economically produced with short life.
Der Bereich der Durchgangsöffnung des Verbundbauteils kann ohne eine Nachbearbeitung als Lasteinleitung, bspw. realisiert mittels einer Schraubverbindung, verwendet werden, so dass dadurch das Verbundbauteil als Lasteinleitungselement eingesetzt werden kann.The region of the passage opening of the composite component can be used without a post-processing as a load introduction, for example, realized by means of a screw, so that thereby the composite component can be used as a load introduction element.
Die Öffnungen der Flachabschnitte des Metallbauteils können mit einer kreisförmigen oder mit einer komplexeren Form, wie bspw. einer Langlochform ausgebildet werden, wobei auch der Stanzrand bzw. der Stanzkragen eine entsprechende Form aufweist. Somit kann bspw. auch eine langlochförmige Durchgangsöffnung des Verbundbauteils realisiert werden.The openings of the flat sections of the metal component can be formed with a circular or with a more complex shape, such as. A slot shape, wherein also the punching edge or the punching collar has a corresponding shape. Thus, for example, a slot-shaped passage opening of the composite component can be realized.
Dadurch dass die Stanzränder die Durchgangsöffnungen in der Wandung des Hohlprofils ausstanzen, sind diese Stanzränder vollständig spielfrei in die Wandung des Hohlprofils eingebettet.Due to the fact that the punched edges punch out the passage openings in the wall of the hollow profile, these punched edges are embedded completely free of play in the wall of the hollow profile.
Besonders vorteilhaft ist es, wenn nach einer Ausgestaltung der Erfindung die Verpressung derart durchgeführt wird, dass die Flachabschnitte flächenschlüssig aufeinander liegen. Damit wird von den Stanzrändern der kongruent übereinander liegenden Öffnungen der Flachabschnitte des Metallbauteils eine metallische Hülse gebildet, über welche bspw. eine Schraubverbindung ohne Setzkraftverluste realisiert werden kann. Da die Stanzränder vollständig spielfrei in die Wandung des Hohlprofils eingebettet sind, ergibt sich zwischen den derart gebildeten Hülsen und dem Kunststoffmaterial eine optimale Passung.It is particularly advantageous if, according to one embodiment of the invention, the pressing is carried out in such a way that the flat sections lie flush against one another. Thus, a metallic sleeve is formed by the punching edges of the congruent superposed openings of the flat portions of the metal component, via which, for example, a screw without Setzkraftverluste can be realized. Since the punching edges are completely free of play embedded in the wall of the hollow profile, resulting between the sleeves thus formed and the plastic material an optimal fit.
Ferner ist nach einer weiteren vorteilhaften Ausgestaltung der Erfindung vorgesehen, dass zur Bildung eines C- oder U-förmigen Metallbauteils die beiden Flachabschnitte endseitig über einen Verbindungsabschnitt verbunden sind. Mit einem solchen Verbindungsabschnitt sind die beiden Flachabschnitte elastisch verbunden, so dass dieses Metallbauteil mit einer Vorspannung in das Hohlprofil eingeführt werden kann, so dass an der vorgesehen Montageposition des Metallbauteils in dem Hohlprofil die Stanzränder der beiden Öffnungen von innen gegen die Wandung des Hohlprofils gedrückt werden und dabei das Metallbauteil in dem Hohlprofil fixiert wird, so dass es auch während des Umformprozesses bzw. bei einem vor der Umformung erfolgenden Aufheizen des Hohlprofils das Metallbauteil an der vorgesehen Montageposition verbleibt.It is further provided according to a further advantageous embodiment of the invention that the two flat portions are connected at the end end via a connecting portion to form a C- or U-shaped metal component. With such a connecting portion, the two flat portions are elastically connected, so that this metal component can be introduced with a bias in the hollow profile, so that pressed at the intended mounting position of the metal component in the hollow profile, the punching edges of the two openings from the inside against the wall of the hollow profile and while the metal component is fixed in the hollow profile, so that it remains at the intended mounting position during the forming process or during a taking place before the reshaping heating of the hollow profile, the metal component.
Vorzugsweise ist bei dieser Ausgestaltung der Erfindung vorgesehen, dass das Hohlprofil mit dem in dasselbe eingelegte Metallbauteil mittels des Umformprozesses im Bereich der Flachabschnitte des Metallbauteils unter Bildung eines flachgepressten Abschnittes des Verbundbauteils derart verpresst wird, dass sich ein in das unverpresste Hohlprofil konusförmig übergehende Übergangsbereich des Verbundbauteils mit einem teilweise formschlüssig anliegenden und schleifenförmig verformten Verbindungsabschnitt des Metallbauteils mit einer Hinterschneidung bildet. Nach dem Umformprozess wird somit zusätzlich ein Formschluss des Metallbauteils mit dem Hohlprofil über die von dem Verbindungsabschnitt des Metallbauteils gebildete Hinter realisiert, der die Festigkeit dieser Anbindung erhöht.Preferably, in this embodiment of the invention, it is provided that the hollow profile is pressed with the metal component inserted in the same by means of the forming process in the region of the flat portions of the metal component to form a flattened portion of the composite component such that a transition region of the composite component which conically merges into the unpressed hollow profile forms with a partially form-fitting adjacent and loop-shaped deformed connecting portion of the metal component with an undercut. After the forming process, a positive connection of the metal component with the hollow profile is thus additionally realized via the rear formed by the connecting portion of the metal component, which increases the strength of this connection.
Schließlich wird weiterbildungsgemäß das Hohlprofil aus faserverstärktem Kunststoff mit einer thermoplastischen Matrix hergestellt.Finally, according to the development of the hollow profile of fiber-reinforced plastic with a thermoplastic matrix.
Die Verbindungsfestigkeit zwischen dem Metallbauteil und dem Hohlprofil kann weiter erhöht werden, indem die Oberfläche des Metallbauteils mit geeigneten Beschichtungen oder Haftungsvermittlungen vorbehandelt werden. Außerdem ist es natürlich möglich, dass mehrere solcher Durchgangsöffnungen erzeugt werden, wodurch weitere Formschlüsse zwischen dem Metallteil und dem Hohlprofil geschaffen werden, die ebenso die Verbindungsfestigkeit zwischen Metallteil und Hohlprofil erhöhen.The bonding strength between the metal component and the hollow profile can be further increased by using the surface of the metal component with suitable coatings or Liability mediation be pretreated. In addition, it is of course possible that a plurality of such through holes are produced, whereby more form-fitting between the metal part and the hollow profile are created, which also increase the connection strength between the metal part and the hollow profile.
