Description

Verfahren zur Herstellung schraubenlinienförmig gewundener Leuchtkörper für elektrische Glühlampen Der Gegenstand der Erfindung bezieht sich auf ein Verfahren zur Herstellung von schraubenlinienförmig gewundenen Leuchtkörpern - sogenannten Wendeldrahtleuchtkörpern -_ insbesondere aus Wolframdraht. für elektrische Glühlampen.Process for the production of helically wound luminous bodies for electric incandescent lamps The subject of the invention relates to a method for the production of helically wound luminous bodies - so-called Spiral wire filaments -_ in particular made of tungsten wire. for electric light bulbs.

Es ist bereits bekannt, gewendelte Leuchtkörper dadurch herzustellen, daß der Leuchtkörperdraht oder -faden auf einen Kern aus Metall oder aus einem organischen Stoffe (Faden) aufgewickelt wird, der später herausgelöst wird. So. wurde bisher bei der Herstellung von gewendelten Fäden der aus organischem Stoffe bestehende Kern während des Sinterns, z. B. in feuchtem Wasserstoff oder Ammoniakgas, entfernt.It is already known to produce coiled luminous bodies by that the filament wire or filament on a core made of metal or an organic Fabric (thread) is wound up, which is later released. So. has been so far in the production of coiled threads the one made of organic matter Core during sintering, e.g. B. in moist hydrogen or ammonia gas removed.

Die bekannten Verfahren sind bei Verwendung von Draht für den Leuchtkörper ziemlich umständlich durchzuführen, weil im Wendeldrahte, wenn er mit der endgültigen Steigung gewickelt wird, auch seiner Achse gleichlaufend gerichtete Kräfte auftreten, die ihn nach Entfernung des Kerns verzerren.The known methods are when using wire for the filament quite awkward to perform because im spiral wires when dealing with the final Incline is wound, forces directed in the same direction also occur on its axis, which distort it after the core is removed.

Geanäß der Erfindung werden diese Nachteile vermieden. Gleichzeitig wird das Verlegen des Leuchtkörpers auf das Traggestell in das Verfahren einbezogen, so daß eine Vereinfachung des gesamten Arbeitsganges herbeigeführt wird. Der Leuchtkörperdraht wird in an sich bekannter Weise auf einen später zu entfernenden Kern aus Seide mit der endgültigen Steigung gewickelt, und der so erhaltene, auf dem Kerne befindliche.Wendeldraht zunächst einem Temperverfahren bei verhältnismäßig niedriger Temperatur unterworfen, um die inneren Spannungen zu beseitigen. Dies gelingt schon bei einer Erhitzung auf ungefähr 26o', :ohne daß dabei der Kern seine Formbeständigkeit verliert. Der Wendeldraht wird dann zusammen mit dem Kerne auf das Traggestell verlegt und in an sich bekannter Weise in einer geeigneten Atmosphäre - beispielsweise in feuchtem Wasserstoff oder in Ammoniakgas - etwa durch Hindurchleiten von Strom geglüht. Auf diese Weise wird der Seidekern durch Verbrennung entfernt.According to the invention, these disadvantages are avoided. Simultaneously the laying of the lamp on the support frame is included in the process, so that a simplification of the entire process is brought about. The filament wire is applied in a manner known per se to a core made of silk to be removed later wound with the final pitch, and the so obtained, located on the core initially subjected to a tempering process at a relatively low temperature, to remove the internal tension. This is already possible with heating to about 26o ', without the core losing its dimensional stability. Of the Helical wire is then laid together with the core on the support frame and in in a manner known per se in a suitable atmosphere - for example in a humid one Hydrogen or in ammonia gas - annealed by passing electricity through it. on in this way the silk core is removed by incineration.

Das Tempern des Leuchtkörpers kann auch nach seinem Verlegen auf das Traggestell erfolgen.The annealing of the filament can also be done after it has been laid on the Carrying frame.
