Description
Die Erfindung bezieht sich auf ein Verfahren zum Herstellen einer Isolation aus Glas für Glühkerzen und besteht darin, daß die zu isolierenden Teile mit einer aus Glaspulver unter Zusatz eines Bindemittels bestehenden, mit einer Flüssigkeit, wie Wasser oder Spiritus, angerührten Masse überzogen, nach (lern Trocknen des Überzugs zusammengefügt, bis zum Schmelzen des Glaspulvers erwärmt und dann bis zum Erkalten vorzugsweise unter leichtem Druck in ihrer Lage gehalten werden.The invention relates to a method for producing a Insulation made of glass for glow plugs and consists in that the parts to be insulated with one consisting of glass powder with the addition of a binder, with one Liquid, such as water or alcohol, coated with the mixed mass, after (learn to dry it of the coating put together, heated until the glass powder melts and then are held in their position until they cool, preferably under slight pressure.
Bei einem bekannten Verfahren zur Herstellung von Zündkerzen mit einem zweiteiligen kerami-, schert, zwischen Fuß und Kopf geteilten Isolator werden die beiden Isolatorteile unter sich und mit dem Kerzengehäuse sowie der Mittelelektrode durch einen Ernailsuhmelzfluß miteinander verbunden. Dabei wird nach dem Einsetzen des Isolatorfußes in ,das Gehäuse Emailpulver eingefüllt und dann der Isolatorkopf aufgesetzt und während des Schmelzens gegen das Fußteil gepreßt. Bei dem Verfahren gemäß der Erfindung sollen die ringförmigen Räume zwischen den stab- und hülsenförmigen Teilen einer Glühkerze mit einem Glasschmelzfluß ausgefüllt werden. Da das Pulver der Schmelzmasse in diesem Fall nicht wie bei dem bekannten Verfahren vergleichsweise wie in ein Gefäß eingefüllt werden kann, ist das bekannte Verfahren für die Herstellung von solchen Glühkerzen, auf die sich die Erfindung bezieht, nicht anwendbar. Das Verfahren gemäß der Erfindung ermöglicht die billige Massenherstellung (auch mit ungelernten Kräften) von Glühkerzen, bei denen das Gehäuse und die Elektroden ineinander angeordnet sind.In a known method for producing spark plugs with a two-part ceramic, sheared insulator divided between foot and head become the both insulator parts under each other and with the spark plug housing and the center electrode connected by a river of Ernailsuhmelz. This is done after insertion the insulator base in, the housing filled with enamel powder and then the insulator head put on and pressed against the foot part during melting. In the process According to the invention, the annular spaces between the rod-shaped and sleeve-shaped Parts of a glow plug are filled with a glass melt flow. Because the powder the melt mass in this case not compared to the known method how can be poured into a vessel is the well-known method of manufacture of such glow plugs to which the invention relates, not applicable. That Process according to the invention enables cheap mass production (also with unskilled workers) of glow plugs, in which the housing and the electrodes interlock are arranged.
Zur Isolierung von Glühdrahtkerzen nach der Zeichnung werden die ineinandersteckenden Elektroden a und h vor dem Zusammenbau mit einem Vberzug c bzw. d aus einer breiartigen Masse versehen. Der Brei wird durch Anrühren von Glaspulver, vorzugsweise Bleiglas, mit Wasser oder Spiritus und einem Bindemittel gewonnen. Als Bindemittel kann zusammen mit Wasser irgendein wasserlöslicher Klebstoff, z.13. Gummiarabikum, oder bei Verwendung von Spiritus, z. B. Schellack, genommen werden. Die Anwendung von Spiritus hat den Vorteil, daß die bestrichenen Teile rasch trocken werden.To isolate glow wire plugs according to the drawing, the nested Electrodes a and h before assembly with a coating c or d of a paste-like material Mass provided. The pulp is made by mixing glass powder, preferably lead glass, obtained with water or alcohol and a binding agent. As a binder can be used together with water any water soluble adhesive, e.g. 13. Gum arabic, or when used of alcohol, e.g. B. shellac, are taken. Using alcohol has that Advantage that the coated parts dry quickly.
Die bestrichenen Elektroden werden nach dem Trocknen des Überzugs zusammengesteckt und in einem Ofen auf eine solche Temperatur erwärmt, daß das Glaspulver schmilzt und zähflüssig wird. Je nach der verwendeten Glassorte liegt diese Tentperatur zwischen 6oo und 700° C. In diesem Zustand werden die Kerzen aus dem Ofen genommen und die Teile, solange der Glasfluß noch zähflüssig ist, leicht zusammengedrückt, bis sie erkaltet sind. Es ist zweckmäßig, die Zeitdauer, während welcher die Kerzen auf der höchsten Temperatur sind, möglichst kurz zu halten. urn lwi Verwendung von Bleiglas eine etwa beginnende Reduktion von Blei aus'dem Glas zu unterbinden.The coated electrodes are after the coating has dried put together and heated in an oven to such a temperature that the glass powder melts and becomes viscous. This temperature depends on the type of glass used between 600 and 700 ° C. In this state, the candles are taken out of the oven and the parts, as long as the glass flow is still viscous, lightly pressed together, until they are cold. It is useful to determine the length of time during which the candles at the highest temperature should be kept as short as possible. urn lwi using Lead glass to prevent any incipient reduction of lead from the glass.
