Abstract
Description
Die Erfindung betrifft ein Verfahren zum Fügen von Bauteilen, insbesondere zum Fügen einer Laufschaufel an einen Rotorgrundkörper bei der Herstellung oder Reparatur eines integral beschaufelten Gasturbinenrotors.The The invention relates to a method for joining components, in particular for joining a blade to a rotor body during manufacture or Repair of an integrally bladed gas turbine rotor.
Bei der Fertigung von Gasturbinen ist das Reibschweißen ein weitverbreitetes Fügeverfahren. Das Reibschweißen gehört zu den sogenannten Pressschweißverfahren, wobei man beim Reibschweißen unter anderem zwischen dem sogenannten linearen Reibschweißen, dem sogenannten Rotationsreibschweißen und dem sogenannten Rührreibschweißen unterscheidet. Beim Reibschweißen werden Bauteile durch Reibung aneinander gefügt bzw. miteinander verbunden. Beim linearen Reibschweißen wird ein Bauteil translatorisch hin- und herbewegt, wohingegen das andere Bauteil stillsteht und mit einer bestimmten Kraft gegen das bewegte Bauteil gedrückt wird. Hierbei passen sich Fügeflächen der miteinander zu verbindenden Bauteile durch Warmverschmieden aneinander an.at Friction welding is a widespread joining process in the manufacture of gas turbines. The friction welding belongs to the so-called pressure welding process, whereby one uses friction welding Among other things, between the so-called linear friction welding, the so-called rotary friction welding and the so-called friction stir welding. When friction welding Components joined together by friction or connected to each other. In linear friction welding is a component translationally reciprocated, whereas the other component stands still and with a certain force against the pressed moving component becomes. Here, joining surfaces of the fit To be interconnected components by hot forging together at.
Bei der aus dem Stand der Technik bekannten Vorgehensweise zum Verbinden bzw. Fügen von Bauteilen über lineares Reibschweißen werden zwei miteinander zu verbindende Bauteile direkt aneinander gerieben, wobei ein Bauteil translatorisch hin- und herbewegt wird und vorzugsweise über das andere Bauteil ein definierter Stauchdruck auf die Fügefläche zwischen den beiden Bauteilen ausgeübt wird. Werden die beiden miteinander zu verbindenden Bauteile direkt aneinander gerieben, so komplexe Klemmvorrichtungen insbesondere am bewegten Bauteile erforderlich. Es kann zu Verformungen an den miteinander zu verbindenden Bauteilen kommen. Des weiteren entstehen bei der Reibbewegung der miteinander zu verbindenden Bauteile freie Fügeflächen im Bereich der Fügezone, die einer möglichen Kontaminierung, zum Beispiel mit Sauerstoff, aufgesetzt sind. Hierdurch kann die Qualität der Fügeverbindung beeinträchtigt werden. Weiterhin muss bei der aus dem Stand der Technik bekannten Vorgehensweise des linearen Reibschweißens am Ende des Schweißvorgangs das linear hin- und herbewegte Bauteil in seiner Amplitude auf Null gefahren werden, und zwar in exakter Ausrichtung zum feststehenden Bauteil. Dabei einzuhaltende Genauigkeiten liegen in der Größenordnung von 0,1 mm. Diese Genauigkeit kann bei den vorhandenen Massen und Kräften nur sehr schwierig bzw. mit großem Aufwand eingehalten werden.at the known from the prior art approach to connect or joining of components over linear friction welding become two components to be connected directly to each other rubbed, with a component is translationally reciprocated and preferably over the other component a defined compression pressure on the joining surface between the two components exercised becomes. Are the two components to be connected directly rubbed against each other, so complex clamping devices in particular required on moving components. It can cause deformations to the come to be connected components. Furthermore arise free in the friction movement of the components to be joined together Joining surfaces in the Area of the joining zone, the one of a possible Contamination, for example, with oxygen, are attached. hereby can the quality the joint connection impaired become. Furthermore, in the known from the prior art Procedure of linear friction welding at the end of the welding process the linear reciprocating component in its amplitude to zero be driven, in exact alignment with the fixed Component. The accuracies to be adhered to are of the order of magnitude of 0.1 mm. This accuracy can only exist with the existing masses and forces very difficult or with a big one Effort to be respected.
Hiervon ausgehend liegt der vorliegenden Erfindung das Problem zu Grunde, ein neuartiges Verfahren zum Fügen von Bauteilen zu schaffen.Of these, Based on the present invention, the problem underlying a novel method for joining to create components.
Dieses Problem wird durch ein Verfahren zum Fügen von Bauteilen gemäß Patentanspruch 1 gelöst.This Problem is solved by a method for joining components according to claim 1 solved.
Erfindungsgemäß umfasst das Verfahren zumindest die folgenden Schritte: a) Bereitstellen von zwei miteinander zu verbindenden bzw. aneinander zu fügenden Bauteilen; b) Bereitstellen eines Fügeteils; c) Ausrichten der beiden miteinander zu verbindenden Bauteile und des Fügeteils, derart, dass das Fügeteil als Einsatz zwischen den beiden miteinander zu verbindenden Bauteilen angeordnet ist; d) Verbinden der beiden Bauteile unter Zwischenanordnung des Fügeteils, dadurch, dass das Fügeteil gegenüber den beiden miteinander zu verbindenden, stillstehenden Bauteilen bewegt wird, und dass insbesondere über beide stillstehenden Bauteile eine Stauchkraft auf die Fügezonen zwischen den beiden stillstehenden Bauteilen und dem Fügeteil ausgeübt wird.According to the invention the method comprises at least the following steps: a) providing of two components to be connected to each other or to be joined; b) providing a joining part; c) aligning the two components to be joined together and of the joining part, such that the joining part as an insert between the two components to be joined together is arranged; d) connecting the two components with intermediate arrangement of the joining part, in that the joining part across from the two connected to each other, stationary components is moved, and that in particular over both stationary components an upsetting force on the joining zones between the two stationary components and the joining part is exercised.
Beim erfindungsgemäßen Verfahren zum Fügen von Bauteilen werden die beiden miteinander zu verbindenden Bauteile nicht direkt aneinander gerieben, sondern vielmehr unter Zwischenschaltung eines als Einsatz dienenden Fügeteils. Die beiden miteinander zu verbindenden Bauteile stehen still, das Fügeteil wird relativ zu den beiden miteinander zu verbindenden Bauteilen bewegt. Über die beiden stillstehenden Bauteile wird ein Stauchdruck auf die Fügeflächen zwischen den miteinander zu verbindenden Bauteilen und dem Fügeteil bereitgestellt bzw. ausgeübt. Mithilfe des erfindungsgemäßen Verfahrens können die beiden Teilschritte des "Reibens" und des "Stauchens" separiert bzw. entkoppelt werden, wodurch mit geringeren Klemmkräften an den Bauteilen gearbeitet werden kann. Hierdurch wird die Gefahr unerwünschter Bauteilverformungen beim insbesondere linearen Reibschweißen reduziert. Weiterhin können die einzuhaltenden Genauigkeiten in der Schweißverbindung einfach realisiert werden, da das Fügeteil am Ende des Schweißprozesses einfach stehen bleiben kann, ohne dass eine genaue Positionierung des Fügeteils eingehalten werden muss.At the inventive method for joining of components are the two components to be joined together not rubbed directly against each other, but rather with the interposition of a as an insert part to be used. The two components to be connected stand still, the adherend becomes relative to the two components to be joined together emotional. about the two stationary components is an upsetting pressure on the joining surfaces between provided to the components to be joined together and the joining part or exercised. Using the method according to the invention can the two sub-steps of "rubbing" and "upsetting" separated or decoupled be, thereby working with lower clamping forces on the components can be. As a result, the risk of undesired component deformation reduced in particular linear friction welding. Furthermore, the to be observed accuracy in the welded joint simply realized be, because the joining part at the end of the welding process Just stand still without having an accurate positioning of the joining part must be complied with.
Das Fügeteil ist vorzugsweise derart bemessen, dass bei Bewegung desselben im Bereich der stillstehenden Bauteile keine freien Fügeflächen entstehen. Hierdurch wird die Gefahr von Kontaminierungen durch zum Beispiel Sauerstoff im Bereich der Fügezonen minimiert.The adherend is preferably dimensioned such that when moving the same in Area of the stationary components no free joining surfaces arise. This will increase the risk of contamination by, for example Oxygen in the region of the joining zones minimized.
Aufgrund des Aufmaßes im Bereich des Fügeteils kann das erfindungsgemäße Reibschweißen nunmehr auch für Reparaturarbeiten eingesetzt werden. Insbesondere eignet sich das Verfahren zur Reparatur von integral beschaufelten Gasturbinenrotoren durch Austausch einer beschädigten Laufschaufel gegen eine neue Laufschaufeln.by virtue of of the oversize in the area of the joining part the friction welding according to the invention can now also for Repair work can be used. In particular, this is suitable Method of repairing integrally bladed gas turbine rotors by replacing a damaged one Blade against a new blades.
