Abstract

The aim of the invention is to provide a simple and thus cost-effective as well as functionally reliable joining of two profile elements, which are provided, in particular, in the form of panel-shaped motor vehicle structural parts, via connecting webs projecting from the profiles adjacent to one another at the joining location. To this end, a joining of this type is characterized by the following features. The connecting webs (3, 4; 13, 14) are joined to one another with positive engagement, and this positive joining is effected by deforming at least one of two interconnected webs (3, 4; 13, 14) with regard to their unconnected state.

Description

Verbindung zweier Profilelemente Connection of two profile elements
Die Erfindung betrifft eine Verbindung zweier Profilelemente, insbesondere in der Form plattenförmiger Kraftfahrzeug- Strukturbauteile, nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a connection of two profile elements, in particular in the form of plate-shaped motor vehicle structural components, according to the preamble of patent claim 1.
Aus DE 197 12 316 AI sind miteinander verbundene Profilelemente bekannt, die in der Form plattenförmiger Kraftfahrzeug-Strukturbauteile vorliegen und über jeweils abragende, komplementär zueinander fügbare, Stege miteinander verbunden sind. Die Verbindung wird dabei durch zusätzlich eingesetzte Verbindungsmittel erzeugt. Diese Verbindungsmittel umfassen Schraubklemmen und Träger, auf die die miteinander zu verbindenden Profilelemente gemeinsam aufgeklemmt werden können. In den Profilelementen müssen spezielle Aufnahmen für die Schraubklemmen vorgesehen sein.From DE 197 12 316 AI interconnected profile elements are known, which are in the form of plate-shaped motor vehicle structural components and are connected to each other via protruding, complementary mutually joinable webs. The connection is created by additional connecting means. These connecting means comprise screw terminals and supports on which the profile elements to be connected can be clamped together. Special receptacles for the screw terminals must be provided in the profile elements.
Die Erfindung beschäftigt sich mit dem Problem, gattungsgemäße Profilelemente ohne einen Einsatz zusätzlicher Verbindungshilfsmittel auf eine möglichst einfache und sichere Weise bleibend verbinden zu können, um auf diese Weise relativ große Bauteile aus einzelnen standardisiert hergestellten Profilelementen aufbauen zu können. Gelöst wird dieses Problem durch eine Ausgestaltung gattungsgemäßer Profilelemente nach den kennzeichnenden Merkmalen des Patentanspruchs 1.The invention is concerned with the problem of being able to permanently connect generic profile elements without using additional connection aids in the simplest and most secure way possible, in order in this way to be able to construct relatively large components from individual, standardized profile elements. This problem is solved by designing generic profile elements according to the characterizing features of patent claim 1.
Vorteilhafte und zweckmäßige Ausgestaltungen sind Gegenstand der Unteransprüche.Advantageous and expedient refinements are the subject of the dependent claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, Profil- elemente, die miteinander verbunden werden sollen, mit abragenden Stegen derart zu versehen, dass die miteinander zu verbindenden Profilelemente über ihre abragenden Stege in einfacher Weise unter gegenseitiger flächenschlüssiger Anlage der Stege aneinander gesetzt werden können. Dabei ist den miteinander zu verbindenden Stegen jeweils eine solche Form gegeben, dass anschließend durch Verformung mindestens eines zweier aneinander liegender Stege eine formschlüssige Verbindung erzielbar ist. Auf einfachste Weise wird eine solche formschlüssige Verbindung dadurch erzielt, dass der zu verformende Steg um den Steg, mit dem er einen Form- schluss bilden soll, mit einem Biegewerkzeug gebogen wird. Der Grad der Verformung muss lediglich ein solches Maß haben, dass durch diese Verformung ein sicherer Formschluss erzielbar ist .The invention is based on the general idea of providing profile elements which are to be connected to one another with projecting webs in such a way that the profile elements to be connected to one another can be placed against one another in a simple manner by means of their projecting webs, with the webs mutually fitting against one another. The webs to be connected to one another are each given such a shape that a positive connection can subsequently be achieved by deforming at least one of two webs lying against one another. Such a form-fitting connection is achieved in the simplest manner in that the web to be deformed is bent with a bending tool around the web with which it is to form a form-fit connection. The degree of deformation need only be such a degree that a secure positive fit can be achieved by this deformation.
Eine erfindungsgemäße Verbindung eignet sich insbesondere für Aluminiumstrangpress-Profilelemente, aus denen größere Kraftfahrzeug-Strukturteile erzeugt werden sollen. Bei Strangpressprofilen, die insbesondere als Hohlprofile herstellbar sind, lassen sich abragende Verbindungsstege besonders leicht und damit rationell anformen.A connection according to the invention is particularly suitable for extruded aluminum profile elements from which larger motor vehicle structural parts are to be produced. In the case of extruded profiles, which can be produced in particular as hollow profiles, protruding connecting webs can be formed particularly easily and thus efficiently.
Die miteinander verbundenen Stege der Profilelemente können zusätzlich zu ihrem Formschluss noch durch eine Klebeverbindung gesichert sein. Bei einer Sicherung durch eine zu- sätzliche Klebeverbindung kann zwischen den im Formschluss miteinander verbundenen Verbindungsstegen ein geschlossener Aufnahmeraum für Klebestoff vorgesehen sein. Dieser Aufnah- meraum besitzt eine Zuführöffnung für das Einfüllen des Klebstoffes .The interconnected webs of the profile elements can also be secured by an adhesive connection in addition to their positive locking. When backed up by a Additional adhesive connection, a closed receiving space for adhesive can be provided between the connecting webs connected to one another in a positive fit. This receiving space has a feed opening for filling in the adhesive.
Vorteilhafte Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt.Advantageous embodiments of the invention are shown in the drawing.
In dieser zeigen:In this show:
Fig. 1 bis 4 unterschiedliche Formschlussverbindungen zweier Strangpress-Hohlprofilelemente .Fig. 1 to 4 different interlocking connections between two extruded hollow profile elements.
Fig. 1 zeigt eine Verbindung zwischen zwei Profilen 1 und 2. An jedes dieser Profile 1 und 2 sind jeweils verformbare, abragende Stege angeformt, nämlich Stege 3 an dem Profilelement 1 und Stege 4 an dem Profilelement 2. Zur Erzielung einer formschlüssigen Verbindung werden diese Stege 3, 4 nach einem vorausgegangenen Fügen der beiden Profilelemente 1 und 2 Formschluss erzeugend umgebogen mit Hilfe eines Biegewerkzeuges .Fig. 1 shows a connection between two profiles 1 and 2. Deformable, projecting webs are formed on each of these profiles 1 and 2, namely webs 3 on the profile element 1 and webs 4 on the profile element 2. To achieve a positive connection, these are Crosspieces 3, 4 are bent after a previous joining of the two profile elements 1 and 2 to produce a positive connection with the aid of a bending tool.
Die Ausgangsform der Stege 3 und 4 vor der Erzeugung der formschlüssigen Verbindung ist in ausgezogenen Linien dargestellt, während die umgebogene, den Formschluss wiedergebende Form mit gestrichelten Linien angedeutet ist . Beide Profilelemente 1 und 2 sind plattenförmige Tragstrukturen für ein Kraftfahrzeug, von denen jeweils lediglich der Verbindungsbereich gezeichnet ist . Bei dem Profilelement 1 handelt es sich bei dem Verbindungsbereich um eine Öffnung innerhalb des Profilelementes, während der Verbindungsbereich des Profilelementes 2 einen Endbereich eines solchen Profilelementes darstellt . Bei der Darstellung in Fig. 2 entspricht das Profilelement 5 dem Profilelement 2 und das Profilelement 6 dem Profil- element 1 in Fig. 1. Das Profilelement 5 ist somit wiederum dasjenige, das zur Verbindung mit einem anderen Bauteil in eine in dem anderen Bauteil vorgesehene Ausnehmung eingeschoben wird. Bei diesem Ausführungsbeispiel werden lediglich die abragenden Stege des Profilelementes 6 für den erfindungsgemäßen Formschluss um die Gegenstege des Profil- elementes 5 verbogen.The initial shape of the webs 3 and 4 before the positive connection is produced is shown in solid lines, while the bent shape, which reflects the positive connection, is indicated by dashed lines. Both profile elements 1 and 2 are plate-shaped support structures for a motor vehicle, of which only the connection area is shown. In the case of the profile element 1, the connection area is an opening within the profile element, while the connection area of the profile element 2 represents an end area of such a profile element. In the illustration in FIG. 2, the profile element 5 corresponds to the profile element 2 and the profile element 6 corresponds to the profile element 1 in FIG. 1. The profile element 5 is in turn the one that is provided for connection with another component in a component provided in the other component Recess is inserted. In this exemplary embodiment, only the projecting webs of the profile element 6 are bent around the counter-webs of the profile element 5 for the form-fitting connection according to the invention.
Die Formschluss-Verbindung nach Fig. 2 besitzt zur Festigkeitserhöhung noch eine zusätzliche Klebeverbindung. Zu diesem Zweck ist zwischen angrenzenden Flächen der Profil- elemente 5 und 6 ein von außen mit Klebstoff ausfüllbarer Aufnahmeraum 7 vorgesehen. Von außen zugänglich ist dieser Aufnahmeraum 7 durch eine Klebstoff-Zuführungsöffnung 8 in dem Profilelement 6.2 has an additional adhesive connection to increase strength. For this purpose, a receiving space 7 that can be filled with adhesive from outside is provided between adjacent surfaces of the profile elements 5 and 6. This receiving space 7 is accessible from the outside through an adhesive feed opening 8 in the profile element 6.
Bei den Ausführungen nach den Fig. 1 und 2 sind die Stege, an die die umzuformenden Stege 3, 4 anzulegen sind, jeweils derart ausgebildet, dass die, den Formschluss insgesamt bildenden Stege nicht hinterschnittartig aneinander liegen. Durch eine für einen Hinterschnitt bei der Verbindung vorgesehene Form des Anlagesteges, an dem der umzuformende Steg 3, 4 anzulegen ist, kann auch ein solcher - hier nicht gezeichneter - Hinterschnitt ohne weiteres erzeugt werden.In the embodiments according to FIGS. 1 and 2, the webs to which the webs 3, 4 to be formed are to be placed are each designed in such a way that the webs forming the overall form fit do not lie against one another like an undercut. Such an undercut, which is not shown here, can also be readily produced by means of a shape of the contact web provided for an undercut in the connection, on which the web 3, 4 to be formed is to be placed.
Bei dem Ausführungsbeispiel nach Fig. 3 entspricht das Profilelement 9 dem Profilelement 2 und das Profilelement 10 dem Profilelement 1 jeweils nach Fig. 1. Die hier zu verformenden Stege 2 sind bezüglich ihres Zustandes wiederum wie Fig. 1 mit durchgezogenen und gestrichelten Linien wiedergegeben. Fig. 4 zeigt eine Eckverbindung von zwei Profilelementen 11 und 12. Dort besitzt jedes der beiden Profilelemente 11, 12 in dem angrenzenden Kantenbereich einen umzuformenden Steg, nämlich einen Steg 13 an dem Profilelement 11 und einen Steg 14 an dem Profilelement 12. Die Art des Umbiegens ergibt sich wiederum aus der Darstellung der Stege 13, 14 in durchgezogenen bzw. gestrichelten Linien.In the exemplary embodiment according to FIG. 3, the profile element 9 corresponds to the profile element 2 and the profile element 10 corresponds to the profile element 1 in each case according to FIG. 1. The webs 2 to be deformed here are shown in their condition as in FIG. Fig. 4 shows a corner connection of two profile elements 11 and 12. There each of the two profile elements 11, 12 has in the adjacent edge region a web to be formed, namely a web 13 on the profile element 11 and a web 14 on the profile element 12. The type of Bending again results from the representation of the webs 13, 14 in solid or dashed lines.
Durch die erfindungsgemäße Fügetechnik liegen einfache und kostengünstige Verbindungen ohne eine notwendige Verwendung von Zusatzteilen vor. The joining technology according to the invention provides simple and inexpensive connections without the need to use additional parts.
