Description

Die Erfindung beschreibt ein Verfahren zum mechanischen Fügen von mindestens einem unteren und einem oberen Formteil mittels eines Hilfsfügeteils.The invention describes a method for mechanically joining at least one lower and one upper mold part by means of an auxiliary joining part.

In der Massenproduktion von Produkten wie Autos werden lang bewährte Fügeverfahren wie Nieten oder Schrauben eingesetzt. Es kommen aber in zunehmenden Maße Materialien wie Faserwerkstoffe zum Einsatz, in denen sich Verbinder, wie Nieten oder Schrauben, allein nicht festsetzen können. Dann kommen Nieten mit einem Schließring oder Schrauben mit einer Schraubmutter zum Einsatz. Die Handhabung von Schließringen oder Schraubmuttern ist in einer Massenproduktion aber aufwendig und fehlerträchtig.In the mass production of products such as cars long-proven joining methods such as rivets or screws are used. However, materials such as fiber materials are increasingly being used, in which connectors such as rivets or screws can not be fixed on their own. Then rivets with a locking ring or screws with a nut are used. The handling of locking rings or nuts is in a mass production but consuming and error prone.

Aus der DE 1 100 394 A sind Leichtmetallkonstruktionen mit Verstärkungselementen in Form von aufgeklebten und optional über zusätzliche Hilfsfügeteile gehaltenen Blechstreifen bekannt. Die Blechstreifen dienen hierbei der Aufnahme örtlicher Spannungsspitzen, welche beispielsweise durch eine Schwingungsbeanspruchung der Leichtmetallkonstruktion auftreten.From the DE 1 100 394 A are light metal structures with reinforcing elements in the form of glued and optionally held on additional auxiliary joining parts metal strip known. The metal strips are used here to record local voltage peaks, which occur for example by a vibration stress of the light metal structure.

So ist in der Patentanmeldung DE 10 2009 044 888.8 ein Verfahren zum Stanznieten von Formteilen offenbart. Dieses Verfahren arbeitet mit Stanznieten, die eine Ringnut besitzen, in die Material der Formteile eingepresst wird. Wenn das Material der Formteile nicht zum Einpressen in die Ringnut geeignet ist, ist dieses Verfahren nicht einsetzbar.So is in the patent application DE 10 2009 044 888.8 discloses a method for the punch riveting of moldings. This method works with punch rivets, which have an annular groove, is pressed into the material of the moldings. If the material of the molded parts is not suitable for being pressed into the annular groove, this method can not be used.

In der Patentschrift DE 10 2010 000 500 B1 ist ein Verfahren zum Fügen von Formteilen aus verschiedenen Materialien mittels eines Stanzniets beschrieben, bei dem ein Schließring für das Festsetzen der Verbindung sorgt. Hier muss für jeden Fügevorgang ein Schließring in eine Matrize eingelegt werden.In the patent DE 10 2010 000 500 B1 is a method for joining molded parts made of different materials by means of a punch rivet described in which a locking ring ensures the setting of the compound. Here, a locking ring must be inserted into a die for each joining process.

In der Gebrauchsmusterschrift DE 20 2010 016 444 U1 ist eine Vorrichtung zur Befestigung von Scharnieren an Türen eines Fahrzeugs beschrieben. Dabei werden verschiedene Blechteile mittels einer durchgesteckten Schraube und einem Absorberelement zusammengepresst. Das Absorberelement weist eine Gewindebohrung für die Schraube auf. Eine Verbindung der Blechteile mit einem Fügeverfahren, das ohne eine Bohrung in dem Absorberelement auskommt, ist nicht vorgesehen.In the utility model DE 20 2010 016 444 U1 a device for fixing hinges to doors of a vehicle is described. Various sheet metal parts are pressed together by means of a screwed through and an absorber element. The absorber element has a threaded bore for the screw. A connection of the sheet metal parts with a joining method, which manages without a bore in the absorber element, is not provided.

In der Patentanmeldung DE 2 229 499 ist eine Blechpressmutter beschrieben, die auf einem Basisblech befestigbar ist. Mit dieser Blechpressmutter soll erreicht werden, dass beim Eindrehen einer Schraube die Mutter genügend Haltekraft auf dem Basisblech besitzt und sie nicht durchdreht. Ein anderes Fügeverfahren als die Verbindung von Blechen mit einer Schraube und einer Mutter ist nicht vorgesehen.In the patent application DE 2 229 499 is a sheet metal press nut described which can be fastened on a base plate. With this sheet metal press nut is to be achieved that when screwing a screw, the mother has enough holding power on the base plate and they do not spin. A joining method other than joining sheets with a screw and a nut is not provided.

Es ist die Aufgabe der Erfindung ein für eine Großserie geeignetes Verfahren zum Fügen von unterschiedlichen Formteilen anzugeben, bei dem die Fügeverbindung auch bei Materialien durchführbar ist, in denen sich ein Hilfsfügeteil nicht allein festsetzen kann.It is the object of the invention to provide a suitable for a large-scale process for joining of different moldings, in which the joint connection is feasible even with materials in which a Hilfsfügeteil can not fix alone.

Diese Aufgabe wird mit dem Verfahren nach Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen des Verfahrens sind in den Unteransprüchen angegeben.This object is achieved by the method according to claim 1. Advantageous embodiments of the method are specified in the subclaims.

Das Verfahren zum mechanischen Fügen ist zum Verbinden von mindestens einem unteren und einem oberen Formteil mittels eines Hilfsfügeteils vorgesehen. Das Hilfsfügeteil ist dabei ein Niet, eine Schraube, ein Bolzen, ein Schweißelement oder ein ähnliches Verbindungselement. Die Verbindung durch das Hilfsfügeteil wird mittels eines ungelochten Schließblechs erzeugt, das in dem oder unter dem unteren Formteil in dem vorgesehenen Fügebereich angebracht ist. Das Hilfsfügeteil verbindet sich mit dem Schließblech, das wiederum mit dem unteren Formteil verbunden ist. Das Schließblech kommt bei diesem Verfahren im Herstellungsprozess mit dem unteren Formteil mit und muss nicht während des Fügens zusätzlich zugeführt werden, was bei herkömmlichen Verfahren zu zusätzlichem Aufwand und zu Fehlern in der Massenproduktion führt.The method of mechanical joining is provided for connecting at least one lower and one upper mold part by means of an auxiliary joining part. The auxiliary joining part is a rivet, a screw, a bolt, a welding element or a similar connecting element. The connection by the auxiliary joining part is produced by means of an unperforated striking plate, which is mounted in or under the lower mold part in the intended joining region. The auxiliary joining part connects to the striking plate, which in turn is connected to the lower molding. The locking plate comes with this process in the manufacturing process with the lower mold part and does not have to be fed during the joining additional, resulting in conventional methods to additional effort and errors in mass production.

Bei einer auf diese Weise hergestellten Verbindung der Formteile kommt es nicht auf die Materialeigenschaften der Formteile an. Somit ist es auch bei Formteilen einsetzbar, die sich nicht direkt mit dem Hilfsfügeteil verbinden lassen oder bei denen eine Verbindung nicht langzeitstabil wäre. Solche Formteile können aus Metall, aus Faserverbundwerkstoffen, aus Kunststoffen oder aus Kombinationen dieser Werkstoffe bestehen.In a compound of the moldings produced in this way, it does not depend on the material properties of the moldings. Thus, it can also be used in the case of molded parts which can not be directly connected to the auxiliary joining part or in which a connection would not be long-term stable. Such moldings may be made of metal, fiber composite materials, plastics or combinations of these materials.

In einer einfachen Ausführungsform des Verfahrens wird das Schließblech vor dem Fügen in dem Fügebereich auf das untere Formteil aufgeklebt. Dabei kann es auch durch zusätzliche Hilfsfügeteile, wie Schrauben oder Nieten, fixiert sein.In a simple embodiment of the method, the striking plate is adhered to the lower molding prior to joining in the joining region. It can also be fixed by additional auxiliary joining parts, such as screws or rivets.

Das Schließblech wird schon beim Herstellungsprozess des unteren Formteils in dem Fügebereich mit diesem verbunden. So kann ein Schließblech auf einen Faserverbundwerkstoff aufgeschweißt sein. Das Schließblech kann auch in das Formteil eingearbeitet sein, etwa als Einlegeteil beim Spritzen oder Gießen eines Kunststoffformteils.The strike plate is already connected in the manufacturing process of the lower molding in the joint area with this. Thus, a strike plate can be welded onto a fiber composite material. The strike plate can also be incorporated in the molded part, for example as an insert when spraying or casting a plastic molding.

Das Schließblech ist vorteilhaft aus einem duktilen Metall oder aus einem thermoplastischen Kunststoff hergestellt. Ein solches Material umfasst das Hilfsfügeteil ohne Probleme und lässt sich preiswert und einfach einsetzen.The strike plate is advantageously made of a ductile metal or of a thermoplastic material. Such a material includes the auxiliary joining part without problems and can be used inexpensively and easily.

Falls für das Fügen eine Schraube vorgesehen ist, wird diese vorteilhaft als selbstschneidende Schraube gewählt.If a screw is provided for the joining, this is advantageously chosen as a self-tapping screw.

Falls für das Fügen ein Niet vorgesehen ist, wird dieser vorteilhaft als Stanzniet gewählt. Durch die Wahl solcher Hilfsfügeteile entfallen zusätzlich Arbeitsgänge. Im Falle anderer Hilfsfügeteile werden die Formteile in den Fügebereichen schon vorgelocht. Auch dann ist ein einfaches Fügen möglich.If a rivet is provided for the joining, this is advantageously chosen as a punch rivet. The choice of such auxiliary joining parts eliminates additional operations. In the case of other auxiliary joining parts, the shaped parts are already pre-perforated in the joint areas. Even then, a simple joining is possible.

Eine besonders feste Verbindung wird erreicht, wenn das Hilfsfügeteil mit einer Ringnut versehen ist, in die sich das Material des Schließblechs beim Fügen hineindrückt.A particularly firm connection is achieved if the auxiliary joining part is provided with an annular groove into which the material of the striking plate pushes during the joining.

Die Festigkeit der Verbindung kann weiter erhöht werden, wenn das Schließblech in dem Fügebereich eine vergrößerte Materialdicke aufweist. Dann wirken größere Kräfte an dem Hilfsfügeteil, auch wenn nur wenig mehr Material eingesetzt wird. Das Material für das Schließblech kann weiter verringert werden, wenn mehrere Fügebereiche auf einem Schließblech zusammengefasst sind und zwischen den Fügebereichen Aussparungen vorgesehen sind.The strength of the connection can be further increased if the striking plate has an increased material thickness in the joining region. Then larger forces act on the auxiliary joining part, even if only a little more material is used. The material for the strike plate can be further reduced if several joining areas are combined on a strike plate and recesses are provided between the joining areas.

Bei dem hier vorgeschlagenen Verfahren zum mechanischen Fügen kann das Hilfsfügeteil quasistatisch, impulsartig oder oszillierend eingebracht werden. Einschränkungen bei den Einbringverfahren bestehen nicht.In the method for mechanical joining proposed here, the auxiliary joining part can be introduced quasi-statically, in a pulse-like manner or in an oscillating manner. There are no restrictions on the methods of introduction.

1 zeigt den Schnitt durch das obere Formteil 8 und das untere Formteil 9, die mittels eines Nagels 1 verbunden sind. An dem unteren Formteil 9 ist das Schließblech 11 mittels der Klebefläche 10 vor dem Verbinden befestigt worden. Der Nagel 1 ist durch die Formteile 8, 9 und durch das Schließblech 11 getrieben. Dabei entsteht eine Ausformung 14 aus dem Schließblech 11, die sich um den Nagel 1 presst und ihm dort einen Halt gibt. 1 shows the section through the upper molding 8th and the lower molding 9 that by means of a nail 1 are connected. At the lower molding 9 is the strike plate 11 by means of the adhesive surface 10 fastened before joining. The nail 1 is through the moldings 8th . 9 and through the strike plate 11 driven. This creates a shape 14 from the strike plate 11 that is around the nail 1 press and give him a stop there.

In 2 und 3 sind die Schritte zur Herstellung einer Nietverbindung zwischen einem oberen Formteil 8 und einem unteren Formteil 9 dargestellt. Die Formteile liegen zwischen der Matrize 7 und dem Pressstempel 6 mit seinem Niederhalter 2. Der Niet 1, hier als Stanzniet mit einem breiten Flachkopf dargestellt, ist in dem Niederhalter 2 geführt. Der Niet 1 weist an seinem Schaft eine Ringnut 5 auf. Unter dem unteren Formteil 9 ist das Schließblech 11 mittels der Klebeschicht 10 befestigt. Das Schließblech 11 weist eine Verdickung 3 auf, die in der Matrize 7 geführt ist. Im nächsten Schritt gemäß 3 wird der Pressstempel 6 mit dem Stanzniet 1 bis auf die Oberfläche des oberen Formteils 8 heruntergefahren und dann durch den Pressstempel 6 eine solche Kraft aufgebracht, dass der Stanzniet 1 die beiden Formteile 8, 9 sowie das Schließblech 11 durchdringt und ein Butzen 18 herausgedrückt wird. Die Fügekraft wird weiter erhöht, so dass sich das Schließblech 11 verformt und sein Material in die Ringnut 5 hineingedrückt wird. Dazu wird auch das Material des Schließblechs 11 im Abstandsbereich zwischen seinem Flansch und der Matrize 7 genutzt. Das Schließblech 11 sitzt jetzt fest auf dem Stanzniet 1 und die Formteile 8, 9 sind fest miteinander verbunden. Der flache Kopf des Stanzniets 1 und der Flansch des Schließblechs 11 bieten dabei eine große Pressfläche, die eine große Festigkeit der Nietverbindung bewirkt.In 2 and 3 are the steps for making a riveted joint between an upper molding 8th and a lower molding 9 shown. The moldings are located between the die 7 and the press stamp 6 with his downholder 2 , The rivet 1 , shown here as a punch rivet with a wide flat head, is in the hold down 2 guided. The rivet 1 has an annular groove on its shaft 5 on. Under the lower molding 9 is the strike plate 11 by means of the adhesive layer 10 attached. The striking plate 11 has a thickening 3 on that in the matrix 7 is guided. In the next step according to 3 becomes the press stamp 6 with the punch rivet 1 down to the surface of the upper molding 8th Shut down and then through the punch 6 applied such a force that the punch rivet 1 the two moldings 8th . 9 as well as the strike plate 11 penetrates and a slug 18 is pushed out. The joining force is further increased, so that the striking plate 11 deformed and its material in the annular groove 5 is pressed into it. This is also the material of the strike plate 11 in the distance between its flange and the die 7 used. The striking plate 11 now sits firmly on the punch rivet 1 and the moldings 8th . 9 are firmly connected. The flat head of the punch rivet 1 and the flange of the strike plate 11 offer a large pressing surface, which causes a high strength of the riveted joint.

In 4 ist eine einfache Form des Schließblechs 11 dargestellt. Es genügt eine einfache flache Scheibe, die beim Fügevorgang von dem Hilfsfügeteil durchdungen und fest mit diesem verbunden wird. Ein Vorlochen ist bei vielen Fügeverfahren nicht notwendig.In 4 is a simple form of strike plate 11 shown. All it takes is a simple flat disc which, during the joining process, is penetrated by the auxiliary joining part and firmly connected to it. Pre-punching is not necessary with many joining methods.

In 5 ist eine Verbindung zwischen dem oberen Formteil 8 und dem unteren Formteil 9 mit zwei Schrauben 1 mit angeformter Pressfläche als Hilfsfügeteile dargestellt. Ein Schließblech 11 gemäß 5, aber ohne Lochungen, ist mit seinen beiden Verdickungen 3 in ein zweilagiges unteres Formteil 9 eingearbeitet. Die Schrauben 1 sind als selbstschneidende Schrauben ausgewählt, damit sie sich direkt beim Eindrehen mit dem Schließblech 11 verbinden können, ohne dass weitere Arbeitsgänge erforderlich sind.In 5 is a connection between the upper molding 8th and the lower molding 9 with two screws 1 represented with integrally formed pressing surface as auxiliary joining parts.
