Es sind stabförmige Heizelemente bekannt, die in rohrförmigen Trägerelementen gelagert sind; eines der bekanntesten Beispiele sind Glühkerzen, bei denen ein stabförmiger Glühstift in einem rohrförmigen Glühkerzenkörper gelagert ist.Rod-shaped heating elements are known which are tubular Carrier elements are stored; one of the most famous Examples are glow plugs, in which a rod-shaped Glow plug stored in a tubular glow plug body is.
Zur Verbindung von Glühstift und Glühkerzenkörper wird beispielsweise der Glühstift in den Glühkerzenkörper eingepreßt; hierbei können nur solche Materialien verwendet werden, die genügend Verformbarkeit und Formfestigkeit für einen solchen Einpreßvorgang aufweisen.To connect the glow plug and glow plug body for example, the glow plug is pressed into the glow plug body; only materials can be used here the sufficient ductility and dimensional stability for have such a pressing process.
Beim Einpressen dürfen auch gewisse Bauteillängen, insbesondere des Glühstifts, nicht überschritten werden, um ein Einknicken dieses Bauteils während des Einpreßvorganges zu vermeiden.When pressing in, certain component lengths, especially the glow plug, not to be exceeded a buckling of this component during the press-in process to avoid.
Darüberhinaus können beim Einpressen Riefen entstehen, die zur Undichtigkeit zwischen Glühstift und Glühkerzenkörper führen.In addition, scoring can occur when pressing in, the leak between glow plug and glow plug body to lead.
Der Erfindung liegt die Aufgabe zugrunde, Verfahren zum Verbinden eines stabförmigen Heizelements mit einem rohrförmigen Trägerelement zur Verfügung zu stellen, bei dem das mit den geschilderten Nachteilen verbundene Einpressen des Heizelementes in das Trägerelement entbehrlich ist; gleichzeitig soll dieses Verfahren nicht von einer bestimmten Bauteillänge zur Vermeidung des Abknickens eines solchen Bauteils abhängig sein; insbesondere sollen aber auch keramische stabförmige Heizelemente mit metallischen Trägerelementen leicht verbunden werden können, wobei die geschilderte Riefenbildung nicht auftreten soll.The invention has for its object methods for Connecting a rod-shaped heating element with a tubular one To provide support element in which the with the disadvantages described pressing in Heating element in the carrier element is unnecessary; simultaneously this method is not intended to be of a particular Component length to avoid kinking Be dependent on the component; in particular, ceramic should also rod-shaped heating elements with metallic support elements can be easily connected, the described Streaking should not occur.
Erfindungsgemäß wird diese Aufgabe durch das Verfahren
nach Anspruch 1 bzw. die Glühkerze nach Anspruch 5 gelöst;
weitere vorteilhafte Ausgestaltungen der Erfindung ergeben
sich aus den nachfolgenden Ansprüchen 2 bis 4 und 6 bis 8.According to the invention, this object is achieved by the method
solved according to
Wesentliches erfindungsgemäßes Merkmal ist die Umformung des stabförmigen Heizelements mit einem Trägerring mittels Magnetumformtechnik, wobei diese Technik beispielsweise unter dem Begriff "MagnetoPuls" der Firma Magnet-Physik Dr. Steingroever GmbH, Köln, Deutschland, angeboten wird.Forming is an essential feature of the invention of the rod-shaped heating element with a carrier ring by means of magnetic forming technology, this technology for example under the term "MagnetoPuls" from Magnet-Physik Dr. Steingroever GmbH, Cologne, Germany becomes.
Die Erfindung wird am bevorzugten Beispiel einer Glühkerze

Magnetumformtechnik ein Trägerring 2 geformt ist, wobei das
Material des Trägerrings 2 elektrisch leitend und mittels
Magnetumformtechnik verformbar ist. In ansich bekannter
Weise führt ein Anschlußpol 5 als Plus-Pol in den Glühstift
1 hinein.Figure 1 schematically shows a glow plug in
Gemäß Figur 2 wird die Anordnung gemäß Figur 1 in einen
Glühkerzenkörper 3 eingebracht, wobei dieses derart erfolgen
kann, daßdie Einpreß- oder Einbringkraft zur Einbringung
der Anordnung in den Glühkerzenkörper 3 auf den Trägerring 2
zur Einwirkung gebracht wird, so daß die Gefahr des Einknikkens
des Glühstiftes 1 mit Anschlußpol 5 gar nicht auftreten
kann, und wobei auch recht dünne Glühstifte 1, und wie im
vorliegenden Fall, aus leichter zu beschädigendem Material,
wie Keramik verwendet werden können. Bei dieser Ausführungsform,
die als einpolig bezeichnet wird, dient der Glühkerzenkörper
3 als Masse oder Minuspol.According to Figure 2, the arrangement of Figure 1 is in one
Bevorzugt wird der Glühkerzenkörper 3 auf den Trägerring
2 mittels Magnetumformtechnik aufgeformt, wie es im
einzelnen etwas später bei den Figuren 4 und 5 beschrieben
wird.
Es ist auch denkbar, bei dieser Ausführungsform anstelle eines Glühstifts aus Keramik einen solchen aus leitfähigem Metall zu verwenden, der aufgrund der erfindungsgemäßen Verfahrensweise nicht die Dicke und Stabilität üblicher Glühstift aufweisen muß; vielmehr erlaubt das erfindungsgemäße Verfahren die Herstellung und Verbindung von sehr dünnwandigen Glühstiften und Glühstiftgehäusen oder -körpern.It is also conceivable instead of this embodiment of a ceramic glow plug one of conductive To use metal due to the invention The procedure is not the thickness and stability more common Must have glow pencil; rather, the invention allows Process the manufacture and connection of very thin-walled glow plugs and glow plug housings or bodies.
Figur 3 zeigt die Anordnung Glühstift 1, Trägerring 4
und Anschlußpol 5 einer anderen erfindungsgemäßen Glühkerzenform.
Hierbei wird wiederum ein Glühstift 1 aus Keramik
verwendet, in den anschlußseitig ein Innenpol 5 hineinragt,
und der anschlußseitig mit einer Kontakthülse 6 verlängert
ist.FIG. 3 shows the arrangement of
Bei dieser Ausführungsform ist der Trägerring 4 zwar
auch wieder aus einem Material, das mittels Magnetumformtechnik
verformbar ist; seine Oberflächen, zumindest die,
die nach außen weisen, sind jedoch isolierend, beispielsweise
mit einer isolierenden Keramikschicht beschichtet,
ausgebildet. Im übrigen ist der Trägerring 4 mittels Magnetumformtechnik
auf den Glühstift 1 aufgebracht; in gleicher
Weise ist die Kontakthülse 6 um den anschlußseitigen Glühstiftendbereich
angeformt.In this embodiment, the
Alternativ kann der Glühstift 1 auch aus Stahl bestehen,
wobei er dann mittels aufgebrachter Keramikschicht
elektrisch isoliert ist.Alternatively, the
Wenn die Kontakthülse 6 einen gleichen äußeren Durchmesser
wie der Trägerring 4 aufweist, ist ihre nach außenweisende
Oberfläche ebenfalls isoliert ausgebildet, beispielsweise
mit einer isolierenden Keramikbeschichtung versehen.
Bevorzugt jedoch ist der äußere Durchmesser des Trägerrings
4 größer als der äußere Durchmesser der Kontakthülse
6, so daß der Körper 3 die Hülse 6 nicht kontaktiert.If the
Bevorzugt besteht der Trägerring 4 aus einer Kupferoder
Aluminiumlegierung, wobei der Ring 4 mit einer Eloxalschicht
oder einer Lackschicht isoliert ist.The
