Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren zum Verschweißen zweier Blechteile gemäß dem Oberbegriff des Patentanspruches 1 sowie eine Werkzeugmaschine gemäß Patentanspruch 4.The present invention relates to a method of welding two sheet metal parts according to the generic term of claim 1 and a machine tool according to claim 4th
Kraftstoffbehälter für Fahrzeuge werden neuerdings
aus Emissionsgründen
wieder aus Stahlblech hergestellt. Aus der
Insbesondere bei Flüssigkeitsbehältern wie z. B. Kraftstoffbehältern muss die Schweißnaht umlaufend dicht sein und eine hohe Nahtqualität aufweisen. Ein Problem beim Verschweißen der beiden Flansche besteht darin, dass die Stirnseiten der Flansche einen gewissen Versatz zueinander aufweisen können. Der Versatz kann hervorgerufen sein durch Toleranzen beim Beschneiden der Behälterhälften im Flanschbereich, durch Formtoleranzen beim Pressen der Behälterhälften sowie durch Fügetoleranzen beim Aneinandersetzen der Behälterhälften sowie durch Fügetoleranzen, die beim Zusammenspannen der Flansche entstehen.Especially with liquid containers such as. B. fuel tanks must the weld be tight all round and have a high seam quality. A problem with weld together of the two flanges is that the end faces of the flanges can have a certain offset to one another. The offset can be caused due to tolerances when trimming the container halves in the flange area Shape tolerances when pressing the container halves and through joining tolerances when Put together the container halves as well Joint tolerances, that arise when the flanges are clamped together.
Für die Herstellung einer sauberen Schweißnaht ist jedoch eine exakte Stoßgeometrie erforderlich. Das heißt, die Stirnseiten der Flansche müssen möglichst in einer Ebene liegen. Versuche haben gezeigt, dass lediglich ein geringer Flanschversatz von weniger als 0,5 mm tolerierbar ist. Dies ist nur mit einem hohen „Abstimmungsaufwand" in der gesamten Prozesskette realisierbar. Trotz erheblicher Anstrengungen ist es äußerst schwierig, eine hinreichend hohe Prozesssicherheit, d. h. eine Begrenzung des Ausschussanteils zu erreichen.For however, the production of a clean weld seam is an exact one impact geometry required. This means, the faces of the flanges must be as possible lie in one plane. Trials have shown that only one small flange misalignment of less than 0.5 mm is tolerable. This is only with a high "coordination effort" in the entire process chain realizable. Despite considerable efforts, it is extremely difficult a sufficiently high level of process reliability, d. H. a limit on the share of rejects to reach.
Aufgabe der Erfindung ist es, ein Verfahren sowie eine Werkzeugmaschine zur Herstellung einer qualitativ hochwertigen Schweißnaht zu schaffen, wobei das Verfahren und die Werkzeugmaschine für Großserieneinsatz geeignet sein sollen.The object of the invention is a Method and a machine tool for producing a qualitative high quality weld to create, the process and the machine tool for large-scale use should be suitable.
Diese Aufgabe wird durch die Merkmale der Patentansprüche 1 und 4 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.This task is due to the characteristics of claims 1 and 4 solved. Advantageous refinements and developments of the invention are the dependent claims refer to.
Das Grundprinzip der Erfindung besteht darin, vor dem Verschweißen der Flansche eine „Null-Versatzsituation" an den Flanschstirnseiten sicherzustellen. Dies wird dadurch erreicht, dass vor dem Verschweißen ein oder beide Flansche auf eine exakt gleiche Flanschlänge gekürzt werden.The basic principle of the invention is in it, before welding the flanges a "zero offset situation" on the flange faces sure. This is achieved by having one before welding or both flanges can be shortened to exactly the same flange length.
Hierzu kann beispielsweise ein Fräswerkzeug verwendet werden, das dem Schweißwerkzeug vorangeführt wird.For this purpose, for example, a milling tool be used, which leads the welding tool.
Vorzugsweise sind das Bearbeitungswerkzeug und das Schweißwerkzeug an einem bewegbaren Werkzeugarm angeordnet. Der Werkzeugarm ist entlang einer vorgegebenen Bahn, d. h. entlang der Stirnseiten der miteinander zu verschweißenden Flansche bewegbar. In Bewegungsrichtung gesehen ist das Bearbeitungswerkzeug, z. B. das Fräswerkzeug in einem festen Abstand vor dem Schweißwerkzeug angeordnet. Somit können durch Verfahren des Werkzeugarms entlang der Flanschstirn seiten in einem einzigen Prozessschritt die Flansche auf gleiche Länge gekürzt und miteinander verschweißt werden.Preferably, the machining tool and the welding tool arranged on a movable tool arm. The tool arm is along a predetermined path, d. H. along the end faces of each other flanges to be welded movable. Seen in the direction of movement is the processing tool, z. B. the milling tool arranged at a fixed distance in front of the welding tool. Consequently can by moving the tool arm along the flange faces the flanges are shortened to the same length in a single process step and welded together become.
