Abstract
Die Erfindung betrifft ein Verfahren zum Herstellen einer Nietverbindung, insbesondere an zumindest zwei aneinander anliegenden Flanschen von Blech-, Guss-, Strangpressprofil- und/oder Kunststoffbauteilen, bei dem ein Niet mit einem Nietkopf und einem hohlen Nietschaft von einer Seite in die Flansche eingetrieben und durch Materialverformung formschlüssig die Verbindung erzeugt. Zur Erzielung verformungsarmer Nietverbindungen wird vorgeschlagen, dass der Nietschaft (18b) in seiner Festigkeit und Konfiguration so ausgebildet wird, dass beim Eintreiben des Halbhohlniets (18) Material der Flansche (16a, 12a) in den Hohlraum (20) des Nietschafts (18b) einfließt und dort formschlüssig gehalten wird.The invention relates to a method for producing a riveted joint, in particular on at least two adjoining flanges of sheet metal, cast iron, extruded and / or plastic components, in which a rivet with a rivet head and a hollow rivet shank driven from one side into the flanges and by material deformation form-fitting the connection produced. To achieve low-deformation rivet connections, it is proposed that the rivet shank (18b) be configured in its strength and configuration such that material from the flanges (16a, 12a) flows into the cavity (20) of the rivet shank (18b) when the half-tubular rivet (18) is driven in and is held there form-fitting.
Description
Die vorliegende Erfindung betrifft ein Verfahren zum Herstellen einer Nietverbindung gemäß dem Oberbegriff des Patentanspruchs 1, einen Niet zur Ausführung des Verfahrens nach dem Patentanspruch 10, sowie eine Bauteilverbindung nach dem Patentanspruch 14.The present invention relates to a method for producing a riveted joint according to the preamble of patent claim 1, a rivet for carrying out the method according to
Beispielsweise im Automobilbau ist es bekannt, dünnwandige Blechbauteile durch Nietverbindungen zu fügen, bei denen der Niet (zum Beispiel ein Halbhohlniet) in die aneinander anliegenden Blechflansche ohne Vorbohren oder dergl. in einem Stanzvorgang eingetrieben wird, wobei unter Verformung sowohl des Flanschmaterials als auch des Niets eine formschlüssige Verbindung geschaffen wird. In der
Die Aufgabe der Erfindung besteht darin, ein Verfahren der gattungsgemäßen Art sowie einen zur Ausführung des Verfahrens geeigneten Halbhohlniet bereitzustellen, bei dem in geringerem Maße Wellungen oder Verformungen auftreten und dennoch eine hochfeste Nietverbindung herstellbar ist.The object of the invention is to provide a method of the generic type and a semi-tubular rivet suitable for carrying out the method, in which corrugations or deformations occur to a lesser extent and yet a high-strength rivet connection can be produced.
Die Aufgabe ist durch die Merkmale des Patentanspruchs 1, 10 oder 14 gelöst. Vorteilhafte und besonders zweckmäßige Weiterbildungen des Verfahrens sowie ein geeigneter Halbhohlniet zur Ausführung des Verfahrens sind Gegenstand der Unteransprüche.The object is solved by the features of
Die Erfindung ist vorrangig für die Herstellung einer Zweiblechverbindung geeignet, so dass nachfolgend die Weiterbildungen der Erfindung speziell anhand der Herstellung einer solchen Zweiblechverbindung offenbart sind. Dieselben Weiterbildungen der Erfindung treffen jedoch auch auf eine Drei- oder Mehrblechverbindung zu.The invention is primarily suitable for the production of a two-sheet connection, so that below the developments of the invention are disclosed specifically with reference to the production of such a two-sheet connection. However, the same developments of the invention also apply to a three or more sheet metal connection.
Erfindungsgemäß wird vorgeschlagen, dass der Nietschaft in seiner Festigkeit und Konfiguration so ausgebildet wird, dass beim Eintreiben des Halbhohlniets Material der Flansche in den Hohlraum des Nietschafts einfließt und dort formschlüssig gehalten wird. Im Gegensatz zum bekannten Halbhohlstanznieten wird dabei der Halbhohlniet als solcher nicht oder nur geringfügig verformt. Stattdessen fließt insbesondere der untere Flansch der Nietverbindung in den Hohlraum des Halbhohlniets und bildet dort an der speziell gestalteten Innenkontur die für den Kraft- und Formschluss wichtige Verklammerung. Die Innenkontur des Halbhohlniet kann durch eine den Hohlraum begrenzende Innenwandung gebildet sein, in der zumindest ein Formschlussabschnitt vorgesehen ist, der gegenüber einer Grundfläche der Innenwandung um ein Versatzmaß vorragt oder zurückgesetzt ist. Mittels des Formschlussabschnitts kann in prozesssicherer Weise das Flanschmaterial im Hohlraum des Nietschafts gehalten werden. Bevorzugt kann Formschlussabschnitt als ein Hinterschnitt ausgeführt sein.According to the invention, it is proposed that the rivet shank be configured in its strength and configuration such that, when the half-tubular rivet is driven in, material of the flanges flows into the cavity of the rivet shank and is retained there in a form-fitting manner. In contrast to the known semi-hollow punch riveting the Halbhohlniet is not or only slightly deformed as such. Instead, in particular, the lower flange of the rivet connection flows into the cavity of the Halbhohlniets and forms there on the specially designed inner contour important for the force and form-fitting clamping. The inner contour of the Halbhohlniet may be formed by an inner wall delimiting the cavity, in which at least one form-fitting portion is provided, which protrudes or is reset by a Versatzmaß opposite a base surface of the inner wall. By means of the form-fitting section, the flange material can be held in the cavity of the rivet shank in a process-reliable manner. Preferably, form-fitting section can be designed as an undercut.
Mit einer solchen speziellen Innenkontur wird der Großteil des verdrängten Volumens im Hohlraum des Niets aufgenommen, wodurch insbesondere eine unzulässige Verformung der Flansche (zum Beispiel Wellungen) in den Randbereichen vermieden bzw. deren Oberflächengüte verbessert ist.With such a special inner contour, the majority of the displaced volume is accommodated in the cavity of the rivet, whereby in particular an impermissible deformation of the flanges (for example corrugations) in the edge regions is avoided or their surface quality is improved.
Wie oben erwähnt, bleibt der Halbhohlniet während des Nietvorgangs verformungsfrei. Das dem Halbhohlniet zugewandte Bauteil kann damit prozesssicher von der Halbhohlniet durchstoßen werden. Im Unterschied dazu kann der Halbhohlniet in das, auf der Gegenhalterseite angeordnete Bauteil bevorzugt nur teilweise eingetrieben werden. Auf diese Weise ergibt sich eine einseitig geschlossene Verbindung, bei der zwischen der Halbhohlniet-Spitze und der dem Halbhohlniet abgewandten Bauteil-Seite eine Restmaterialstärke verbleibt.As mentioned above, the half-tubular rivet remains free of deformation during the riveting operation. The semi-tubular rivet facing component can thus be pierced by the Halbhohlniet process reliable. In contrast, the semi-tubular rivet can preferably only be partially driven into the component arranged on the counterholder side. In this way, a unilaterally closed connection results in which a residual material strength remains between the semi-tubular rivet tip and the component side facing away from the semi-tubular rivet.
Der besagte Hohlraum des Nietschafts kann mit einem oder mit mehreren Hinterschnitten ausgeführt werden. Ferner kann der Nietschaft an seinem freien Ende mit einer konischen Anfasung oder einer Abrundung versehen werden, die das Eintreiben des Halbhohlniets bzw. das Durchstanzen des dem Stempelwerkzeug zugewandten Flansches und den Materialfluss in dessen Hohlraum begünstigt.The said cavity of the rivet shank can be executed with one or more undercuts. Furthermore, the rivet shank can be provided at its free end with a conical chamfering or a rounding which promotes the driving in of the semi-tubular rivet or the punching of the flange facing the stamping tool and the flow of material into its cavity.
Der Halbhohlniet kann besonders bevorzugt durch ein- oder mehrstufiges Kalt- und/oder Warmumformen hergestellt werden, wobei durch anschließendes Anstauchen des Nietschafts der Hinterschnitt und/oder die Anfasung erzeugt wird. Damit wird eine hohe Duktilität und Festigkeit des Halbhohlniets bei niedrigen Fertigungskosten erreicht, insbesondere wenn der Niet aus Stahl oder aus Aluminium hergestellt und durch eine Wärmebehandlung gehärtet wird.The half-hollow rivet can be produced particularly preferably by one-stage or multi-stage cold and / or hot forming, wherein the undercut and / or the chamfering is produced by subsequent upsetting of the rivet shank. Thus, a high ductility and strength of the Halbhohlniets is achieved at low manufacturing costs, especially if the rivet made of steel or aluminum and cured by a heat treatment.
Es wird bevorzugt vorgeschlagen, beim Nietvorgang einen Gegenhalter bzw. eine Matrize zu verwenden. Diese kann keine oder nur eine geringfügige Überhöhung, bevorzugt < 1 mm, aufweisen. Dies trägt ebenfalls zu einer erhöhten Oberflächengüte der Nietverbindung bei, was zum Beispiel für Anbauteile an den Flanschen wie Türdichtungen, Zierleisten, etc. vorteilhaft ist. Zudem kann um den den Halbhohlniet beaufschlagenden Stempel ein im Durchmesser zumindest ungefähr dem Gegenhalter entsprechender Niederhalter verwendet werden.It is preferably proposed to use a counter holder or a die during the riveting process. This can have no or only a slight elevation, preferably <1 mm. This also contributes to an increased surface quality of the riveted joint, which is advantageous, for example, for attachments to the flanges such as door seals, trim strips, etc. In addition, around the Halbhohlniet acting punch in diameter be used at least approximately the counter holder corresponding hold-down.
Ein verfahrensgemäßer Halbhohlniet mit einem Nietkopf und einem im Wesentlichen zylindrischen Nietschaft kann bevorzugt einen einen Hinterschnitt aufweisenden Hohlraum mit einem innenliegenden Abschnitt größeren Durchmessers und zumindest einen am Schaftende ausgebildeten Abschnitt kleineren Durchmessers aufweisen.A semi-tubular rivet according to the invention with a rivet head and a substantially cylindrical rivet shank may preferably have an undercut cavity with an inner portion of larger diameter and at least one smaller diameter portion formed on the shank end.
Zusätzlich kann der Nietschaft am Schaftende mit einer konischen Anfasung bzw. einer Abrundung versehen sein, wobei der Hinterschnitt und die Anfasung so ausgeführt sind, dass der hohle Nietschaft eine im Wesentlichen durchgehend gleiche Wandstärke aufweist. Dies stellt insbesondere eine hohe Verformungsfestigkeit des Halbhohlniets sicher, womit ein sicheres und gezieltes Einfließen des beim Nietvorgang verdrängten Materials in den Hohlraum und dessen Verklammerung mit dem Hinterschnitt gegeben ist.In addition, the rivet shank may be provided at the shank end with a conical chamfering, wherein the undercut and the chamfering are designed so that the hollow rivet shank has a substantially uniform wall thickness. This ensures, in particular, a high deformation resistance of the half-tubular rivet, with which a secure and targeted inflow of the material displaced during the riveting process into the cavity and its interlocking with the undercut is ensured.
Des Weiteren kann der Nietschaft verrundet in den im Durchmesser größeren Nietkopf übergehen, um eine gleichmäßige Spannungsverteilung und Kraftübertragung in der Nietverbindung herzustellen. Alternativ dazu kann der Nietkopf auch als ein sogenannter Flachkopf ausgebildet sein, der nicht verrundet, sondern stufenförmig in den Nietschaft übergeht.Furthermore, the rivet shank can be rounded into the larger diameter rivet head in order to produce a uniform stress distribution and force transmission in the riveted joint. Alternatively, the rivet head may be formed as a so-called flat head, which does not rounded, but gradually merges into the rivet shank.
Schließlich besteht ein besonders bevorzugter Einsatz der Nietverbindung an dünnwandigen Karosserie-Bauteilen von Kraftfahrzeugen, bei denen die aneinander anliegenden Flansche eine Breite von bevorzugt < 13 mm aufweisen, wobei dennoch die Nietverbindung ohne Auftreten unzulässiger Wellungen oder Verwerfungen an den Randbereichen mit hoher Festigkeit und verbesserter Oberflächengüte ausführbar ist.Finally, there is a particularly preferred use of the riveted joint to thin-walled body parts of motor vehicles, in which the abutting flanges have a width of preferably <13 mm, yet the rivet without occurrence of undue curls or distortions at the edges with high strength and improved surface quality is executable.
