Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Verbinden von Bauteilen gemäß dem Oberbegriff der Patentansprüche 1 und 3.The invention relates to a method and a device for connecting components according to the preamble of claims 1 and 3.
Eine solches Verfahren und eine solche Vorrichtung kommen dort zur Anwendung, wo aufschmelzbare, beschichtete Bauteile aus Metall stoffschlüssig zu einer Baueinheit zu verbinden sind. Ein sehr großes Anwendungsgebiet ist die Herstellung von Karosserien für Fahrzeuge.Such a procedure and one Devices are used where fusible, coated Components made of metal cohesive are to be connected to a unit. A very large area of application is the production of car bodies.
Das dauerhafte Verbinden, insbesondere das Verschweißen solcher Bauteile erfolgt vorzugsweise mit Hilfe energiereicher Strahlung, die beispielsweise mittels einer Laserquelle oder einer Elektronenstrahlkanone erzeugt wird. Als Laserquelle eigenen sich vorrangig Diodenlaser, Festkörperlaser und Gaslaser. Bauteile, die zur Fertigung von Karosserien verwendet werden, sind meist aus Stahl gefertigt. Üblicher Weise sind sie mit Schutzschichten aus Zink versehen, das eine niedrigere Verdampfungstemperatur als der Stahl selbst aufweist.The permanent connection, especially that weld together such components are preferably made with the help of high-energy radiation, that for example by means of a laser source or an electron beam gun is produced. Diode lasers are primarily suitable as laser sources, Solid state lasers and Gas lasers. Components used in the manufacture of car bodies are mostly made of steel. They are usually with Protective layers made of zinc provide a lower evaporation temperature than the steel itself has.
Beim Verschweißen so gefertigter Bauteile entsteht Zinkdampf, der zu Schmelzauswürfen und Porenbildung im Bereich der Schweißnaht führen kann. Die Schädigung der Schweißnaht durch den Zinkdampf wird durch das Ausbilden eines Spaltes zwischen den zu verschweißenden Bauteilen vermieden. Über diesen Spalt kann der Zinkdampf entweichen, der sich beim Verbinden der Bauteile an deren Grenzflächen bildet. Der Spalt wird beim Schweißen kurzer Schweißnahtelemente durch eine entsprechende Formgebung der Bauteile beim Tiefziehen oder durch eine Bearbeitung der Bauteile vor dem Schweißen erzeugt. Bei diesen Verfahren werden an einem oder beiden Bauteilen im Bereich der späteren Schweißnaht Distanznoppen oder Riefen ausgebildet. Es besteht auch die Möglichkeit, lokal Material auf- oder abzutragen, so dass Durchlässe geschaffen werden, über die der Zinkdampf entweichen kann. Ferner ist es auch üblich, die Beschichtungen der Bauteile im Bereich der auszubildenden Schweißnaht zu entfernen.When welding components manufactured in this way Zinc vapor, which leads to expectoration of enamel and can lead to pore formation in the area of the weld seam. The damage to the Weld by the zinc vapor by forming a gap between the one to be welded Components avoided. about this gap can escape the zinc vapor that forms when connecting of the components at their interfaces forms. The gap becomes when welding short weld seam elements by appropriate shaping of the components during deep drawing or generated by machining the components before welding. With these methods, one or both components in the area the later weld spacer knobs or grooves. There is also the possibility of local material or remove, so that culverts be created about that the zinc vapor can escape. Furthermore, it is also common that Coatings of the components in the area of the weld seam to be formed remove.
Diese Maßnahmen erfordern zusätzliche Arbeitsschritte bei der Fertigung. Zudem sind die hierfür verwendeten Werkzeuge aufwendig gestaltet, damit die erforderliche Einhaltung der nötigen engen Spaltformtoleranzen erreicht wird. Eine solche Ausbildung der Bauteile im Bereich der späteren Schweißnahtelemente und die Herstellung der hierfür notwendigen Werkzeuge erfordert entsprechendes Expertenwissen in Konstruktion, Werkzeugbau und Fertigung. Durch diesen Aufwand werden die Produktkosten erhöht.These measures require additional ones Steps in manufacturing. In addition, the ones used for this Tools designed so that the required compliance the necessary narrow gap shape tolerances is achieved. Such training the Components in the area of the later weld elements and the making of this necessary tools requires appropriate expertise in Design, tool making and manufacturing. Through this effort the product cost increases.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren aufzuzeigen, mit dem Bauteile der eingangs genannten Art über eine einwandfreie Schweißnaht unter Umgehung des bekannten Aufwands verbunden werden können. Ferner liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung zu schaffen, mit der ein solches Verfahren durchgeführt werden kann.The invention is based on the object Show method with which components of the type mentioned above via a flawless weld can be connected bypassing the known effort. Further the invention has for its object to provide a device with which such a procedure can be carried out.
Die Aufgabe, das Verfahren betreffend, wird durch die Merkmale des Patentanspruchs 1 gelöst.The task regarding the procedure is solved by the features of claim 1.
Die Aufgabe, die Vorrichtung betreffend, wird durch die Merkmale des Patentanspruchs 3 gelöst.The task regarding the device is solved by the features of claim 3.
Weitere erfinderische Merkmale sind in den abhängigen Ansprüchen gekennzeichnet.Other inventive features are in the dependent claims characterized.

Die Erfindung beschränkt sich nicht nur auf das hier beschriebene Ausführungsbeispiel. Vielmehr umfasst sie alle Variationen des Verfahrens und der Vorrichtung, die dem Kern der Erfindung zugeordnet werden können. Das gilt insbesondere für das Verschweißen von mehr als zwei aufeinander gestapelten Bauteilen wie sie oben beschrieben sind.The invention is limited not only on the embodiment described here. Rather includes they all variations of the method and the device that the Core of the invention can be assigned. This is especially true for welding more than two stacked components as described above are.
