Description
,Verfahren zur: Herstellung von Zündkerzen Gegenstand der Erfindung äst ein Verfahren zur Herstellung von Zündkerzen für Expläsionsmotoren, bei welchem die einzelnen Teile der Kerze durch einen in dem Gehäusekörper sitzenden Schmelzflußring aus Emaille o. dgl. nicht stromleitender Isoliermasse miteinander verbunden sind., Process for: Manufacture of spark plugs Subject matter of the invention Aest a process for the production of spark plugs for exploding engines, in which the individual parts of the candle by a melt flow ring seated in the housing body made of enamel or the like. Non-conductive insulating material are connected to one another.
Das Wesen der Erfindung besteht darin, daß die pulverförmig auf den ;eingesetztenunteren Isolator in das Kerzengehäuse -eirege= brachte S,chtnelzmasse unter der Preßwiirkung der bis zu blattdünnem Abstand axial gegeneinander .geführten beiden Isolatoren. verschmolzen wird. Man erreicht dadurch,, daß die- in der Schmelzmasse-sich bildenden-Luft- und Gasbläschen, die beim Gebrauch der Kerze Zündstörungen hervorrufen vrürden, restlos verdrängt werden, sd daß der Zündstift von einem fugenfreien zusammenhängenden Isoliermantel umgeben ist.The essence of the invention is that the powder on the ; inserted lower insulator into the plug housing under the pressing effect of the axially guided up to a sheet-thin distance from one another both isolators. is merged. One achieves thereby ,, that the - in the melt mass - itself air and gas bubbles that cause ignition problems when the candle is used vrürden, be completely displaced, sd that the firing pin from a joint-free, coherent Insulating jacket is surrounded.
Den bekannten Zündkerzen gegenüber, -beidenen die verbindende S,chmelzflußmasse als massiger Körper von hohem Ausmaß in dem Kerzengehäuse sitzt, so daß beim Betrieb schädliche Spannungen an den Berührungsflächen unvermeidlich sind, wird erfindungsgemäß der umfassende Hals des 'in etwa mittlerer Höhe des Kerzengehäuses sitzenden Schmelzflußringes recht schmal ausgebildet, damit die einzelnen, stofflich verschiedenen Teile der Kerze nur kurz gefaßt sind und völlig unabhängig voneinander sich frei ausdehnen können.Opposite the known spark plugs, the connecting S, melt flux masses to both of them sits as a massive body of large size in the plug housing, so that during operation harmful tensions on the contact surfaces are unavoidable, is according to the invention the encompassing neck of the 'melt flow ring, which is located approximately midway up the candle housing formed quite narrow, so that the individual, materially different parts of the Candles are only brief and expand freely, completely independently of one another can.
Bei dem auf der Zeichnung im Längsschnitt dargestellten Ausführungsbeispieleiner derartigen Zündkerze ist a der mit Gewindesockel ai und Elektroden b versehene Kerzenkörper, in welchen die den Zündstiftd mit etwas Spielraum umgebenden Isolierkörper f, g aus Porzellan, Steatit o. dgl. nicht stromleitendem Stoff mit ebenfalls, etwas Spielraum gegen die Gehäusewandung ,eingesetzt sind. Der die .einzelnen Teile ,a, f, g, d der Kerze zu :einem Ganzen verbindende S.chmelzflußring h besteht aus Emaille o. dgl. nicht stromleitender Masse, die gleichzeitig auch wärmeisolierend wirkt und sich beim Schmelzen mit den einzelnen sie berührenden Teilen der Kerze chemisch verbindet: Die Herstellungsweise der Kerze ist folgende : - . Nachdem der untere Isolierkörper f in das Kerzengehäuseaeingesetzt ist, wird die durch. Mahlen von Emaillestücken hergestellte Schmelzmasse in pulverförmigem Zustandund in-entsprechender Menge auf den Isolierkör# -per f in das Kerzengehäuse-.eingebrächt. Letzteres-wird nunmehr bis zum Wiederschmelzen der Masse in einem entsprechenden Ofen auf etwa Hellrotglut erhitzt. Gleichzeitig wird der obere -Isolator g bis auf blattdünnen Abstand .axial gegen den unteren Isolator f gepreßt, wodurch namentlich im -Steg-,des Verbindungsringesk die in der Schmelzmasse auftretenden -Luft- und Gasbläschen restlos verdrängt werden. Nachdem die Kerzenteile unter Beibehaltung der Preßwirkung wiedererkaltet sind, ist die Kerze fertig zum Gebrauch.In the embodiment of such a spark plug shown in longitudinal section in the drawing, a is the plug body provided with a threaded base ai and electrodes b, in which the insulating body f, g made of porcelain, steatite or the like, which surrounds the ignition pind with some clearance, is also made of non-conductive material, some clearance against the housing wall are used. The individual parts, a, f, g, d of the candle: the melting flow ring h, which connects a whole, consists of enamel or similar non-conductive material, which at the same time also has a heat-insulating effect and when melted with the individual parts in contact with it the candle chemically connects: The manufacturing method of the candle is as follows: -. After the lower insulating body f is inserted into the plug housing a, the through. Milling of enamel pieces produced melt mass in powdery state and in the appropriate amount on the insulating body -per f in the candle housing-. The latter is now heated until the mass has melted again in a suitable oven to about a bright red glow. At the same time, the upper isolator g is pressed axially against the lower isolator f, except for a thin sheet, so that the air and gas bubbles occurring in the melt are completely displaced in the web and the connecting ring. After the candle parts have cooled down again while maintaining the pressing effect, the candle is ready for use.
