Demgegenüber besteht die Aufgabe der vorliegenden Erfindung darin, ein Verfahren zur Herstellung von mehrteiligen Kraftfahrzeugteilen bereitzustellen, bei dem mindestens ein Teil des Kraftfahrzeugteiles aus thermoplastischem Kunststoff besteht, das durch Widerstandsheizen aufgeschmolzen wird, um mit dem anderen Teil verbunden/verschweißt zu werden.In contrast, the object of the present invention is to provide a method for producing multi-part motor vehicle parts in which at least one part of the motor vehicle part consists of thermoplastic material which is melted by resistance heating in order to be connected / welded to the other part.

Diese Aufgabe wird durch das in Anspruch 1 wiedergegebene Verfahren bzw. dem in Anspruch 7 angegebenen Bauteil gelöst. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen und der Beschreibung.This object is achieved by the method reproduced in claim 1 or the component indicated in claim 7. Advantageous refinements result from the subclaims and the description.

Erfindungsgemäß ist erkannt worden, dass, wenn ein Verfahren zur Herstellung von mehrteiligen Kraftfahrzeugteilen bereitgestellt wird, bei dem mindestens ein Teil des Kraftfahrzeugteiles aus thermoplastischem Kunststoff besteht, das durch elektrisches Widerstandsheizen aufgeschmolzen wird, um mit dem anderen Teil bei Anlage gezielt verbunden oder verschweißt zu werden, wozu in dem mindestens einen Teil ein elektrisches Widerstandsheizelement eingebettet ist, das beim Verbinden der zwei Teile mit Strom beaufschlagt wird, um durch Widerstandswärme ein Aufschmelzen und somit Verbinden der zwei Teile zu erreichen, wobei das Widerstandsheizelement elektrisch mit mindestens einem Anschluss verbunden ist, um über den Anschluss das Widerstandsheizelement mit Strom zu beaufschlagen, es möglich ist den Vorgang der Teileherstellung zu vereinfachen, die Verbindung reversibel auszugestalten und das andere Teil aus unterschiedlichsten Materialien mit dem ersten Teil zu verbinden bzw. zu verschweißen.According to the invention, it has been recognized that if a method for the production of multi-part motor vehicle parts is provided in which at least one part of the motor vehicle part consists of thermoplastic material that is melted by electrical resistance heating in order to be specifically connected or welded to the other part when in contact , for which an electrical resistance heating element is embedded in the at least one part, which is supplied with current when the two parts are connected in order to achieve melting and thus connection of the two parts by means of resistance heat, the resistance heating element being electrically connected to at least one connection to to apply current to the resistance heating element via the connection, it is possible to simplify the process of part production, to make the connection reversible and to connect or weld the other part made of different materials to the first part .

Mit anderen Worten wird das mindestens eine bzw. erste Teil bei der Herstellung mit elektrischen Widerstandsheizelement samt Anschluss ausgestaltet.In other words, the at least one or first part is configured with an electrical resistance heating element including a connection during manufacture.

Zur Verbindung der zwei Teile müssen diese nur aufeinander aufgelegt werden, Strom durch den Anschluss in das Widerstandsheizelement eingebracht werden, um den Thermoplast aufzuschmelzen, und die Abkühlung abgewartet werden. Somit können beide Teile einfach verbunden werden, was auch - soweit eine Stromquelle vorhanden ist - in Werkstätten, Produktionsanlagen oder auch bei Notfallreparaturen möglich wird.To connect the two parts, they only need to be placed on top of one another, current must be introduced through the connection into the resistance heating element in order to melt the thermoplastic and wait for it to cool down. This means that both parts can be easily connected, which is also possible - if there is a power source - in workshops, production facilities or even for emergency repairs.

Dabei wird der mindestens eine Anschluss mit elektrisch leitenden Elementen des Widerstandsheizelements über eine Nadelklemme verbunden. Dies erlaubt eine sichere, aber dennoch einfache Kontaktierung der elektrisch leitenden Elemente in dem Widerstandsheizelement zur späteren Beaufschlagung mit Strom.The at least one connection is connected to electrically conductive elements of the resistance heating element via a needle clamp. This allows reliable, but nevertheless simple, contact to be made with the electrically conductive elements in the resistance heating element for subsequent application of current.

Indem das Widerstandsheizelement gemeinsam mit dem Anschuss und der Nadelklemme oberflächennah in das mindestens eine Teil bei dessen Herstellung eingebettet ist, ist die spätere Verwendung besonders einfach, da nur die zwei Teile (und der Stromanschluss) gehandhabt werden müssen.Since the resistance heating element, together with the connection and the needle clamp, is embedded close to the surface in the at least one part during its manufacture, later use is particularly easy, since only the two parts (and the power connection) have to be handled.

Dazu kann die Nadelklemme zwei über ein Scharnier auf einander zu bewegliche Nadelbacken aufweisen, deren Nadeln aufeinander zu gerichtet sind. Die Nadelbacken klemmen also das Widerstandsheizelement zwischen sich ein, wobei die Nadeln in das Material eintauchen und die elektrisch leitenden Elemente selbst kontaktieren. Dies kann rein mechanisch und/oder durch ein gleichzeitiges Aufschmelzen des Materials des Widerstandsheizelements erfolgen.For this purpose, the needle clamp can have two needle jaws that can be moved towards one another via a hinge have, the needles are directed towards each other. The needle jaws clamp the resistance heating element between them, the needles dipping into the material and contacting the electrically conductive elements themselves. This can be done purely mechanically and / or by simultaneous melting of the material of the resistance heating element.

Vorzugsweise wird als Widerstandsheizelement ein Kohlenstofffasertape, insbesondere ein unidirektionales Kohlenstofffasertape, besonders bevorzugt ein thermoplastisches, unidirektionales Kohlenstofffasertape eingesetzt, dessen elektrisch leitende Carbonfasern von den Nadeln der Nadelklemme kontaktiert werden. Die Verwendung des Kohlenstofffaser(tape)materials hat gleichzeitig den weiteren Vorteil der Versteifung des Bauteils.A carbon fiber tape, in particular a unidirectional carbon fiber tape, particularly preferably a thermoplastic, unidirectional carbon fiber tape, whose electrically conductive carbon fibers are contacted by the needles of the needle clamp, is preferably used as the resistance heating element. The use of carbon fiber (tape) material also has the further advantage of stiffening the component.

Falls nötig, kann z. B. lokal Energie zum Aufschmelzen durch Induktion, also elektromagnetische Felder, in das Widerstandsheizelement eingebracht werden.If necessary, e.g. B. local energy for melting by induction, so electromagnetic fields, are introduced into the resistance heating element.

Das Verfahren erlaubt in vorteilhafter Weise die Verbindung des ersten Teils aus thermoplastischem Kunststoff mit dem weiteren Teil, dessen Materialauswahl nicht beschränkt ist. Das andere, zweite Teil kann z. B. aus einem Thermoplasten, einem Duroplasten oder Metall bestehen.The method advantageously allows the connection of the first part made of thermoplastic material to the further part, the choice of materials of which is not restricted. The other, second part can, for. B. consist of a thermoplastic, a thermosetting plastic or metal.

Zur Verbesserung der Verbindung bzw. Erhöhung der Stabilität kann das andere, zweite Teil mechanische Strukturen zur Verstärkung der Verbindung der zwei Teile aufweisen, die von aufgeschmolzenem Thermoplast um- bzw. hinterlaufen werden, wie z. B. Pilzköpfe, Hinterschnitte, Zapfen, Ausnehmungen etc.To improve the connection or to increase the stability, the other, second part can have mechanical structures to reinforce the connection of the two parts. B. mushroom heads, undercuts, tenons, recesses, etc.

Auch kann das andere, zweite Teil eine chemische Beschichtung zur Verbesserung des Haftvermögens vom aufgeschmolzenen Thermoplast aufweisen.The other, second part can also have a chemical coating to improve the adhesion of the melted thermoplastic.

Vorzugsweise sind der Anschluss und die Nadelklemme einstückig ausgestaltet.The connection and the needle clamp are preferably designed in one piece.

Die Erfindung betrifft ebenfalls ein mehrteiliges Kraftfahrzeugteil mit mindestens einem Teil aus thermoplastischem Kunststoff, in dem ein elektrisches Widerstandsheizelement eingebettet ist, welches elektrisch mit mindestens einem elektrischen Anschluss verbunden ist, der mit elektrisch leitenden Elementen des Widerstandsheizelements über eine Nadelklemme verbunden ist, wobei die Nadelklemme zwei über ein Scharnier aufeinander zu bewegliche Nadelbacken aufweist, deren Nadeln aufeinander zu gerichtet sind, welches bevorzugt in dem angegebenen Verfahren einsetzbar ist.The invention also relates to a multi-part motor vehicle part with at least one part made of thermoplastic material, in which an electrical resistance heating element is embedded, which is electrically connected to at least one electrical connection which is connected to electrically conductive elements of the resistance heating element via a needle clamp, the needle clamp having two has needle jaws movable towards one another via a hinge, the needles of which are directed towards one another, which can preferably be used in the specified method.

Darin ist das Widerstandsheizelement vorzugsweise ein Kohlenstofffasertape, insbesondere ein unidirektionales Kohlenstofffasertape, besonders bevorzugt ein thermoplastisches, unidirektionales Kohlenstofffasertape, dessen elektrisch leitende Kohlenstofffasern von den Nadeln der Nadelklemme kontaktiert sind. Erfindungsgemäß sind der Anschluss und die Nadelklemme oberflächennah in das mindestens eine Teil eingebettet.In this, the resistance heating element is preferably a carbon fiber tape, in particular a unidirectional carbon fiber tape, particularly preferably a thermoplastic, unidirectional carbon fiber tape, the electrically conductive carbon fibers of which are contacted by the needles of the needle clamp. According to the invention, the connection and the needle clamp are embedded near the surface in the at least one part.

Mit anderen Worten, das erste Teil aus thermoplastischem Kunststoff kann im ersten Schritt für das erfindungsgemäße Verfahren wie folgt in einem Spritzgießverfahren hergestellt werden:

  • - Einklemmen des Widerstandsheizelements in einer Nadelklemme;
  • - Öffnen der Spritzgießform;
  • - Einlegen und Fixieren des Widerstandsheizelements mit der Nadelklemme in der Spritzgießform, so dass der Anschluss beim Spritzen frei bleibt;
  • - Schließen der Spritzgießform;
  • - Überspritzen des Widerstandsheizelements mit der Nadelklemme;
  • - Abkühlen und Auswerfen des fertigen Teils.
In other words, the first part made of thermoplastic material can be produced in an injection molding process in the first step for the method according to the invention as follows:
  • - clamping the resistance heating element in a needle clamp;
  • - opening the injection mold;
  • - Insertion and fixation of the resistance heating element with the needle clamp in the injection mold so that the connection remains free during injection;
  • - closing the injection mold;
  • - Overmolding of the resistance heating element with the needle clamp;
  • - cooling and ejection of the finished part.

Anschließend kann das Kraftfahrzeugteil selbst hergestellt werden, indem das erste Teil über den oder die Anschlüsse mit Strom beaufschlagt wird, um den thermoplastischen Kunststoff aufzuschmelzen, das weitere Teil darauf platziert bzw. aufgedrückt wird und die entstandene Verbindung beim Abkühlen erstarrt.The motor vehicle part itself can then be produced by applying current to the first part via the connection or connections in order to melt the thermoplastic material, the further part is placed or pressed onto it and the resulting connection solidifies as it cools.
