Abstract
Die Erfindung betrifft ein Hohlprofilbauteil aus einem endlosfaserverstärkten thermoplastischen Kunststoff, das eine Lasteinleitungsstelle (L) aufweist, für deren Aussteifung außenseitig auf einen Bauteil-Wandabschnitt (9) ein Verstärkungselement (11) aus einem kurzfaserverstärkten thermoplastischen Kunststoff aufgespritzt ist. Erfindungsgemäß weist die Lasteinleitungsstelle (L) des Hohlprofilteils (2) zumindest ein, insbesondere metallisches Anbindungselement (1) für eine Bauteilanbindung auf.The invention relates to a hollow profile component made of an endless fiber-reinforced thermoplastic material, which has a load introduction point (L), for the stiffening of which is externally sprayed on a component wall portion (9), a reinforcing element (11) made of a short fiber reinforced thermoplastic. According to the invention, the load introduction point (L) of the hollow profile part (2) has at least one, in particular metallic connecting element (1) for a component connection.
Description
Die Erfindung betrifft ein Hohlprofilbauteil aus einem faserverstärkten thermoplastischen Kunststoff nach dem Oberbegriff des Patentanspruches 1 sowie ein Verfahren zur Herstellung eines solchen Hohlprofilbauteils nach dem Patentanspruch 10.The invention relates to a hollow profile component made of a fiber-reinforced thermoplastic material according to the preamble of claim 1 and to a method for producing such a hollow profile component according to claim 10.
Aus einem solchen Hohlprofilbauteil kann im Fahrzeugbau eine Tragstruktur hergestellt sein, zum Beispiel ein zwischen den A-Säulen verlaufender Modulquerträger. Aufgrund der Materialeigenschaften des thermoplastischen Kunststoffes können komplexe Lasteinleitungskonzepte umgesetzt werden. Thermoplaste (zum Beispiel Polyamide) zeichnen sich nämlich dadurch aus, dass diese über der Schmelztemperatur erweichen und umformbar sind. Nach dem Unterschreiten der Schmelztemperatur erstarrt das Thermoplast wieder bei Erhalt einer neuen geometrischen Form. In Kombination mit kurzfaserverstärkten Spritz- oder Pressmassen können die Hohlprofilbauteile weiter funktionalisiert werden.From such a hollow profile component can be made in vehicle a support structure, for example, extending between the A-pillars module cross member. Due to the material properties of the thermoplastic material, complex load introduction concepts can be implemented. Thermoplastics (for example, polyamides) are characterized by the fact that they soften above the melting temperature and are deformable. After falling below the melting temperature, the thermoplastic solidifies again upon receipt of a new geometric shape. In combination with short-fiber-reinforced injection or molding compounds, the hollow profile components can be further functionalized.
Aus der
Die Aufgabe der Erfindung besteht darin, ein Hohlprofilbauteil sowie ein Verfahren zu dessen Herstellung bereitzustellen, bei dem die Funktionalität des Hohlprofilbauteils bei insgesamt einfacher Herstellung gesteigert werden kann.The object of the invention is to provide a hollow profile component and a method for its production, in which the functionality of the hollow profile component can be increased with a total of simple production.
Die Aufgabe ist durch die Merkmale der Patentansprüche 1 oder 10 gelöst. Bevorzugte Weiterbildungen der Erfindung sind in den Unteransprüchen offenbart.The object is solved by the features of claims 1 or 10. Preferred embodiments of the invention are disclosed in the subclaims.
Gemäß dem kennzeichnenden Teil des Patentanspruches 1 ist die Lasteinleitungsstelle des Hohlprofilbauteils funktionell dahingehend erweitert, dass es zusätzlich zumindest ein, insbesondere metallisches Anbindungselement für eine Bauteilanbindung aufweist. Auf diese Weise können in fertigungstechnisch einfacher Weise stabile Anbindungskonzepte am Hohlprofilbauteil realisiert werden.According to the characterizing part of claim 1, the load introduction point of the hollow profile component is functionally extended to the effect that it additionally has at least one, in particular metallic connecting element for a component connection. In this way, stable connection concepts can be realized on the hollow profile component in manufacturing technology simple way.
In einer Ausführungsform kann das Hohlprofilbauteil rohrförmig ausgeführt sein, wobei das Anbindungselement in den hohlzylindrischen Innenraum des Hohlprofilteiles eingesetzt ist. Das Anbindungselement kann beispielhaft eine metallische Buchse sein, die am Außenumfang zumindest eine Hinterschneidung aufweist, etwa eine umlaufende Ringnut. Im fertig gestellten Hohlprofilbauteil kann sowohl ein Hohlprofilbauteil-Wandabschnitt als auch das außenseitig aufgespritzte Verstärkungselement formschlüssig in die Hinterschneidung des Anbindungselementes einragen. In einer technischen Umsetzung kann das Anbindungselement (das heißt insbesondere die obige Buchse) in eine nach außen offene Stirnseite des Hohlprofilbauteils eingesetzt sein. Beispielhaft kann eine Stirnseite des Anbindungselementes und der stirnseitige Öffnungsrand des Hohlprofilbauteils in Axialrichtung betrachtet flächenbündig miteinander abschließen. Die oben erwähnte Buchse kann beispielshafte eine hülsenförmige Schraubbuchse sein, in die ein angrenzendes Bauteil verschraubbar ist.In one embodiment, the hollow profile component can be designed tubular, wherein the connecting element is inserted into the hollow cylindrical interior of the hollow profile part. By way of example, the attachment element can be a metallic bushing which has at least one undercut on the outer circumference, for example a peripheral annular groove. In the finished hollow profile component, both a hollow profile component wall section and the externally sprayed reinforcing element can project positively into the undercut of the connection element. In a technical implementation, the connection element (that is to say in particular the above-mentioned socket) can be inserted into an end face of the hollow profile component which is open towards the outside. By way of example, an end face of the connection element and the end-side opening edge of the hollow profile component, viewed in the axial direction, can terminate flush with each other. The above-mentioned bush can be, for example, a sleeve-shaped threaded bush into which an adjacent component can be screwed.
Alternativ dazu kann das in dem Hohlprofilbauteil eingesetzte Anbindungselement einen zusätzlichen Verbindungsabschnitt aufweisen, der mit einem Überstand von der Hohlprofilbauteil-Stirnseite vorragt. Der Verbindungsabschnitt des Anbindungselementes kann in diesem Fall in ein weiteres Hohlprofilbauteil eingesetzt sein.Alternatively, the connecting element used in the hollow profile component may have an additional connecting portion, which protrudes with a projection from the hollow profile component end face. The connecting portion of the connecting element may be used in this case in another hollow profile component.
Zur Herstellung des oben angegebenen Hohlprofilbauteils wird zunächst ein Hohlprofilbauteil-Vorformling (zum Beispiel rohrförmig) bereitgestellt. Anschließend wird das Anbindungselement in die stirnseitige Öffnung des Hohlprofilbauteils eingesteckt. Die so erhaltene Vormontageeinheit wird in einem folgenden Einlegeschritt als ein Einlegerteil in eine Kavität eines Spritzgießwerkzeuges eingelegt. In einem nachfolgenden Fügeschritt wird dann die flüssige Ausgangskomponente des Verstärkungselementes unter Druck und Wärme in die Spritzgießwerkzeugkavität eingespritzt. Beim Einspritzvorgang wird sowohl ein Bauteilwandabschnitt des Vorformlings als auch das Verstärkungselement-Material formschlüssig mit dem Anbindungselement verpresst. Insbesondere kann sowohl ein Wandabschnitt des Vorformlings als auch das Verstärkungselement-Material formschlüssig in die Hinterschneidung (das heißt Ringnut) des Anbindungselementes eingepresst werden.To produce the above-mentioned hollow profile component, a hollow profile component preform (for example tubular) is first provided. Subsequently, the connection element is inserted into the frontal opening of the hollow profile component. The pre-assembly thus obtained is inserted in a subsequent insertion step as an insert part in a cavity of an injection mold. In a subsequent joining step, the liquid starting component of the reinforcing element is then injected under pressure and heat into the Spritzgießwerkzeugkavität. At the Injection process, both a component wall portion of the preform and the reinforcing element material is positively pressed with the connecting element. In particular, both a wall section of the preform and the reinforcing element material can be pressed into the undercut (that is to say annular groove) of the connecting element in a form-fitting manner.
Allgemein ausgedrückt wird somit der oben erwähnte Vorformling bereits endkonturnah bereitgestellt und erfolgt im Spritzgießprozess eine Umformung des Vorformlinges in seine Endkontur, und zwar mit gleichzeitigem Aufspritzen des Verstärkungselementes.In general terms, therefore, the above-mentioned preform is already provided close to final contour and takes place in the injection molding process, a deformation of the preform into its final contour, with simultaneous spraying of the reinforcing element.
In einer weiteren Ausführungsform kann das Hohlprofilbauteil zur Aussteifung der Lasteinleitungsstelle eine Doppelwandstruktur aufweisen, in der zwei gegenüberliegende Wandabschnitte des Hohlprofilbauteils unter Überbrückung des Hohlprofil-Innenraums in Anlage gebracht sind oder zumindest bis auf einen geringen Abstand zusammengeführt sind. Die Doppelwandstruktur der Lasteinleitungsstelle kann an einer Innenkante in einen Übergangsabschnitt übergehen, an dem sich ein querschnittserweiterter Wandabschnitt des Hohlprofilbauteiles anschließt. Bevorzugt ist die Lasteinleitungsstelle mit ihrer Doppelwandstruktur an einer Endseite des Hohlprofilbauteils gebildet. In diesem Fall ist daher die Doppelwandstruktur im Vergleich zum querschnittserweiterten Wandabschnitt des Hohlprofilbauteils abgeflacht ausgeführt. Gegebenenfalls kann zwischen der Doppelwandstruktur und dem Übergangsabschnitt die Bauteilsteifigkeit reduziert sein. Zur Erhöhung der Bauteilsteifigkeit kann bevorzugt das Verstärkungselement in einem Inneneckbereich angespritzt sein, der zwischen der Doppelwandstruktur und dem Übergangsabschnitt aufgespannt ist.In a further embodiment, the hollow profile component for stiffening the load introduction point can have a double wall structure in which two opposite wall sections of the hollow profile component are brought into abutment with bridging of the hollow profile interior or at least brought together to a small distance. The double wall structure of the load introduction point can pass at an inner edge into a transition section, which is followed by a cross-sectional widened wall section of the hollow profile component. Preferably, the load introduction point is formed with its double-wall structure on one end side of the hollow profile component. In this case, therefore, the double wall structure is flattened compared to the cross-sectional widened wall portion of the hollow profile component. If appropriate, the component rigidity can be reduced between the double-wall structure and the transition section. In order to increase the component stiffness, the reinforcing element may preferably be injection-molded in an inner corner region, which is spanned between the double-wall structure and the transition section.
Das an der Lasteinleitungsstelle integrierte Anbindungselement kann in diesem Fall ein Verbindungsbolzen, etwa ein Schraubbolzen sein, der durch das Verstärkungselement und durch die Doppelwandstruktur des Hohlprofilbauteils geführt ist und an dem ein weiteres Bauteil anbindbar ist.In this case, the connecting element integrated at the load introduction point can be a connecting bolt, for example a screw bolt, which is guided through the reinforcing element and through the double-wall structure of the hollow profile component and to which another component can be connected.
Zur Herstellung des obigen Hohlprofilbauteils wird zunächst der rohrförmige Vorformling an seiner Lasteinleitungsstelle unter Bildung der Doppelwandstruktur in einem Presswerkzeug umgeformt. Anschließend wird in einem Spritzgießprozess das Verstärkungselement aufgespritzt. Im Unterschied zur ersten Ausführungsform erfolgt somit die Umformung des Vorformlings und das Aufspritzen des Verstärkungselementes in aufeinanderfolgenden Prozessschritten.To produce the above hollow profile component, first of all the tubular preform is deformed at its load introduction point to form the double wall structure in a pressing tool. Subsequently, the reinforcing element is sprayed in an injection molding process. In contrast to the first embodiment, the deformation of the preform and the spraying of the reinforcing element take place in successive process steps.
Die vorstehend erläuterten und/oder in den Unteransprüchen wiedergegebenen vorteilhaften Aus- und/oder Weiterbildungen der Erfindung können – außer zum Beispiel in den Fällen eindeutiger Abhängigkeiten oder unvereinbarer Alternativen – einzeln oder aber auch in beliebiger Kombination miteinander zur Anwendung kommen.The advantageous embodiments and / or further developments of the invention explained above and / or reproduced in the dependent claims can be used individually or else in any desired combination with one another, for example in the case of clear dependencies or incompatible alternatives.
