Abstract
Description
Die Erfindung betrifft ein Verfahren zum Verbinden von Fügeteilen, insbesondere zum Verbinden von Karosserieblechteilen durch Schweißen und Kleben.The The invention relates to a method for joining parts to be joined, in particular for connecting body panels by welding and Glue.
Fahrzeugkarosserien sollen u. a. eine geringe Masse und eine hohe Steifigkeit aufweisen. Eine Karosserie besteht aus einer Vielzahl von Leichtbau-Einzelteilen, die miteinander verbunden sind.vehicle bodies should u. a. have a low mass and high rigidity. A body consists of a variety of lightweight components, which are interconnected.
Um eine gewünschte Steifigkeit zu sichern, werden die Teile durch Schweißen miteinander verbunden. Ein bevorzugtes Schweißverfahren ist das Punktschweißen, wobei die Schweißpunkte automatisiert gesetzt werden. Um die Zahl der erforderlichen Schweißpunkte zu mindern und bei besonders hohen Anforderungen an die Steifigkeit, ist es bekannt, Karosserieteile durch Punktschweißen in Kombination mit Kleben zu verbinden. Klebverbindungen zeichnen sich durch eine hohe Scher- und Zugfestigkeit aus und bieten einen verbesserten Korrosionsschutz durch Verschluss der Fügespalte. Ein Metallklebstoff besteht aus organischen oder anorganischen Stoffen, die temperaturanfällig sind. Die Klebstoffe können beim Abbinden die Ausbildung eines Schweißpunktes beeinträchtigen. Ebenso können sich die beim Schweißen entstehende Wärme und Dämpfe negativ auf die Festigkeit der Klebverbindung auswirken.Around a desired one To secure rigidity, the parts are welded together by welding connected. A preferred welding method is spot welding, wherein the welds be set automatically. To the number of required welds and for particularly high rigidity requirements, It is known to combine body parts by spot welding in combination with Bonding to connect. Adhesive connections are characterized by a high Shear and tensile strength and provide improved corrosion protection Closure of the joint gap. A metal adhesive consists of organic or inorganic substances, the temperature sensitive are. The adhesives can during setting affect the formation of a weld point. Likewise when welding resulting heat and vapors negative affect the strength of the adhesive bond.
Weiterhin ist es bekannt, Karosserieteile zu verkleben und mechanisch durch Stanznieten oder Durchsetzfügen zu verbinden. Beim Nieten sind Niete als Hilfsfügeteile erforderlich. Beim Durchsetzfügen wird die Oberfläche der zu fügenden Teile sichtbar verformt.Farther It is known to glue body parts and mechanically through Punch rivets or clinching connect to. When riveting rivets are required as auxiliary joining parts. At the Clinching becomes the surface the one to be joined Parts visibly deformed.

Aufgabe der Erfindung ist es, ein Verfahren zum Verbinden von Fügeteilen zu entwickeln, dass mit geringem Aufwand an Kosten und Material eine hinsichtlich Festigkeit und Zuverlässigkeit verbesserte Verbindung zwischen Fügeteilen ermöglicht.task The invention is a method for joining joining parts to develop that with little effort in terms of cost and material a compound improved in strength and reliability between parts to be joined allows.
Die Aufgabe wird mit einem Verfahren gelöst, welches durch die Verfahrenschritte nach Anspruch 1 gekennzeichnet ist. Vorteilhafte Ausgestaltungen des Verfahrens ergeben sich aus den Unteransprüchen.The Task is solved by a method which by the method steps characterized according to claim 1. Advantageous embodiments of the method emerge from the dependent claims.
Gemäß der Erfindung wird bei einem Verfahren zum Verbinden von Fügeteilen durch Kleben und Stoffverbinden in Vorbereitung des Stoffverbindens eine Klebstoffschicht partiell entfernt. Das partielle Entfernen des Klebstoffes und das Stoffverbinden können vorzugsweise durch eine Wärmewirkung von Laserstrahlen durchgeführt werden. Ein besonders geringer Aufwand ergibt sich, wenn die Fügeteile nach dem Kleben mittels Laserstrahlen verschweißt werden. In diesem Fall dienen die Laserstrahlen dem partiellen Entfernen von Klebstoff und dem Setzen einer Schweißnaht in den Bereichen, wo der Klebstoff entfernt wurde. Das partielle Entfernen des Klebstoffes und das Verschweißen kann gleichzeitig oder nacheinander durchgeführt werden.According to the invention is used in a method for joining adherends by gluing and fabric bonding in preparation of the substance connection, an adhesive layer partially away. The partial removal of the adhesive and the substance bonding may preferably by a warming effect performed by laser beams become. A particularly low cost arises when the joining parts after the gluing be welded by means of laser beams. In this case serve the laser beams to the partial removal of adhesive and the Put a weld in the areas where the glue was removed. The partial Removing the adhesive and welding can be done simultaneously or sequentially carried out become.
Beim Kleben können sowohl physikalisch als auch chemisch abbindende Klebstoffe zum Einsatz kommen. Die Auswahl eines Klebstoffes richtet sich nach den gewünschten Eigenschaften der Klebverbindung, wie Festigkeit, Dichtigkeit und Korrosionsschutz. Beim partiellen Entfernen des Klebstoffs durch die Wärmewirkung von Laserstrahlen kommt vorzugsweise ein Klebstoff zum Einsatz, der rückstandsfrei verdampft und der das Ausbilden einer Schweißverbindung fördert.When bonding, both physically and chemically setting adhesives can be used. The choice of an adhesive depends on the desired properties of the adhesive bond, such as strength, impermeability and corrosion protection. When partial removal of the adhesive by the thermal effect of laser beams is preferably an adhesive used, the back vaporizes free-standing and promotes the formation of a welded joint.
Das Verfahren ist vorzugsweise beim Verbinden von beschichteten oder unbeschichteten Blechen anwendbar.The Method is preferably when joining coated or uncoated sheets applicable.
