Description
Die Erfindung betrifft ein Verfahren zum thermischen Fügen zweier aus Materialien mit unterschiedlichen Wärmeausdehnungskoeffizienten bestehender Bauteile nach der im Oberbegriff der Ansprüche 1 und 3 näher definierten Art. Des weiteren betrifft die Erfindung eine Vorrichtung zum thermischen Fügen zweier aus Materialien mit unterschiedlichen Wärmeausdehnungskoeffizienten bestehender Bauteile gemäß dem Oberbegriff von Anspruch 9.The The invention relates to a method for thermal joining two made of materials with different thermal expansion coefficients existing components according to the in the preamble of claims 1 and 3 closer Furthermore, the invention relates to a device for thermal joining two of materials with different thermal expansion coefficients existing components according to the preamble of claim 9.
Aus
der
Die
Bei aus dem allgemeinen Stand der Technik bekannten Verfahren zum thermischen Fügen, wie beispielsweise dem Laserstrahllöten, kommt es aufgrund der erforderlichen Wärmeeinbringung bei der Herstellung von metallischen Mischverbindungen aus Materialkombinationen mit unterschiedlichen thermischen Ausdehnungskoeffizienten, insbesondere beim Verbinden eines Aluminium- mit einem Stahlwerkstoff, zu einer Relativbewegung zwischen den Fügepartnern, da die unterschiedlichen thermischen Ausdehnungskoeffizienten zu unterschiedlichen Längungen der beiden Bauteile führen. Durch das Erstarren des Lots werden diese Relativbewegungen eingefroren, was zu Problemen hinsichtlich der Maßhaltigkeit der erzeugten Werkstücke sowie zu einem Verzug der Bauteile führen kann.at Thermal process known from the general state of the art Put, such as the laser beam soldering, it comes from the required heat input in the production of metallic mixed compounds from material combinations with different thermal expansion coefficients, in particular when connecting an aluminum and a steel material, to a Relative movement between the joining partners, because the different thermal expansion coefficients too different elongations lead the two components. The solidification of the solder causes these relative movements to be frozen, resulting in problems regarding the dimensional accuracy of the produced workpieces as well lead to a delay of the components can.
Es ist daher Aufgabe der vorliegenden Erfindung, ein Verfahren und eine Vorrichtung zum thermischen Fügen zweier aus Materialien mit unterschiedlichen Wärmeausdehnungskoeffizienten bestehender Bauteile zu schaffen, durch welches bzw. welche trotz der unterschiedlichen Längung der Bauteile maßhaltige und spannungsfreie Werkstücke hergestellt werden können.It is therefore an object of the present invention, a method and a device for thermal joining two of materials with different thermal expansion coefficients existing components to create by which or which despite the different elongation the components dimensionally stable and stress-free workpieces can be produced.
Erfindungsgemäß wird diese Aufgabe durch die in Anspruch 1 genannten Merkmale gelöst.According to the invention this Problem solved by the features mentioned in claim 1.
Durch die erfindungsgemäße gezielte Reduzierung der Temperatur des Bauteils aus dem Material mit dem höheren Wärmeausdehnungskoeffizienten und die damit verbundene Reduzierung der geometrischen Ausbreitung der thermisch beeinflussten Zone wird die sich aufgrund der Erwärmung desselben ergebende Ausdehnung so kompensiert, dass im Idealfall beide Bauteile sich um denselben Betrag längen, so dass sich keine unterschiedliche Längung ergibt und ein maßhaltiges Werkstück hergestellt werden kann. Auch die sich ansonsten ergebenden Verspannungen zwischen den Bauteilen treten durch die erfindungsgemäße Lösung nicht nur oder in erheblich geringerer Ausprägung auf, da sich beide Bauteile beim Abkühlen im wesentlichen gleich verhalten können.By the targeted according to the invention Reduction of the temperature of the component from the material with the higher CTE and the associated reduction in geometric propagation the thermally affected zone becomes due to the heating of the same resulting expansion compensated so that, ideally, both components lengthen by the same amount, so that no different elongation results and a dimensionally stable workpiece can be produced. Also the otherwise resulting tension between the components do not occur by the solution according to the invention only or to a significantly lesser extent, since both components on cooling can behave essentially the same.
Ein alternatives Verfahren ergibt sich aus den Merkmalen von Anspruch 3.One alternative method results from the features of claim Third
Alternativ zu der Kühlung des Bauteils mit der höheren Wärmeausdehnung kann auch das Bauteil mit der größeren Wärmeausdehnung erwärmt werden, um eine im wesentlichen gleiche Längenausdehnung der beiden Bauteile zu erreichen und damit die bereits oben genannten Vorteile hinsichtlich Maßhaltigkeit und Verspannungsfreiheit zu erzielen.alternative to the cooling of the component with the higher thermal expansion can also be the component with the greater thermal expansion to be heated a substantially equal length extension of the two components to achieve and thus the above-mentioned advantages in terms of dimensional accuracy and to achieve freedom from distortion.
In einer sehr vorteilhaften Ausgestaltung der Erfindung kann vorgesehen sein, dass die Breite des sich an die Fügezone anschließenden, erwärmten bzw. gekühlten Bereichs erheblich größer als die Breite der Fügezone ist. Durch eine ausreichende Breite des gekühlten bzw. erwärmten Bereichs wird sichergestellt, dass sich der beschriebene vorteilhafte Effekt auch bei der Herstellung einer Vielzahl von Werkstü cken nacheinander im Sinne einer Serienfertigung einstellt.In a very advantageous embodiment of the invention can be provided be that the width of the adjoining the joining zone, heated or cooled Area considerably larger than the width of the joining zone is. By a sufficient width of the cooled or heated area it is ensured that the described advantageous effect also in the production of a variety of workpieces successively sets in the sense of a series production.
Selbstverständlich können die beiden Verfahren auch kombiniert werden, beispielsweise um keine zu starke Abkühlung bzw. Erwärmung erforderlich zu machen.Of course, the Both methods can also be combined, for example, none too much cooling or warming to make necessary.
Eine die oben genannte Aufgabe lösende Vorrichtung ist in Anspruch 9 angegeben.A the above object releasing device is specified in claim 9.
Mit der erfindungsgemäßen, in dem sich an die Fügezone anschließenden Bereich vorgesehene Kühleinrichtung der erfindungsgemäßen Vorrichtung lässt sich das erfindungsgemäße Verfahren besonders einfach realisieren.With the inventive, in to the joining zone subsequent Area provided cooling device the device according to the invention can be the inventive method very easy to realize.
Zusätzliche Bauteile der erfindungsgemäßen Vorrichtung können vermieden werden, wenn die Kühleinrichtung so ausgebildet ist, dass sie zum Andrücken des aus dem Material mit dem höheren Wärmeausdehnungskoeffizienten bestehenden Bauteils an das andere Bauteil geeignet ist.Additional components of the device according to the invention can be avoided if the cooling device is designed such that it can be used for pressing the material made of the material with the higher heat coefficient of expansion of existing component to the other component is suitable.
