Description
Anordnung an Metallspritzpistolen Es ist bereits bekanntgeworden ( vgl. I'atcnt 53 r o69 g bei Schoopschen Met:dlspritzpistcden das Schmelzen des Metalls mit Hilfe einer Hochfrequenzspule vorztuiehin(°n. Es ist *)rt eine Spule benutzt, die zylinderförmig( Gestalt besitzt. Derartige Anordnungen besitzen den \achteiL daß die Hattpteru=äriritorg in der 1@Titte dieser Spule erfolgt, so daß entweder die Hälfte der Spule ungenutzt bldht oder aber das Metall beim Durchlaufen der gesamten Spule am linde wieder abgekühlt ist.Arrangement on metal spray guns It has already become known ( See I at 53 r o69 g in Schoopschen Met: spray guns melt the metal with the help of a high-frequency coil vorztuiehin (° n. It is *) rt a coil is used, which has a cylindrical shape. Such arrangements have the \ achteiL that the Hattpteru = äriritorg takes place in the 1 @ Titte of this coil, so that either half of the coil is unused or the metal when going through the whole bldht The coil on the linde has cooled down again.
(lcniäl#l der Erl-indung soll die Spulenforrn derart ausgebildet werden, daß sich die: Heizwirkung von einem zum anderen Ende der Spule hin steigert. Das kann so geschehen, wie das b;-ispielstveise die Fig. i zeigt, da1i der zu schipelzende Draht i die kegelförmig gewickelte Hochfre_luenzspule 2 von links nach rechts durchläuft. in der Windung kleinsten Durclniiess(,rs tritt die= höchste Erwärmung auf, so dal,v, wie in Yg. 2 dtirgc-steillt, wenn die Spule iii eirein keramischen K.ürpur eingebettet ist und der hirlauf der Smönn in Pfeilrichtung erfolgt, die Spule, die gleichzeitig damit düsenförmigen Charakter besitzt, das Zersprühen des Metalls an der engsten Stelle hervorruft.(According to the invention, the coil shape should be designed in such a way that that the: heating effect increases from one to the other end of the coil. That can be done like the b; example in fig Wire i runs through the conically wound Hochfre_luenzspule 2 from left to right. in the winding of the smallest diameter (, rs the = highest heating occurs, so that, v, as in Yg. 2 dtirgc-steillt when the coil iii is embedded in a ceramic body is and the hirlauf der Smönn takes place in the direction of the arrow, the coil, which at the same time thus has a nozzle-shaped character, the atomizing of the metal at the closest Place.
1?ine besonders vorteilhafte Ausbildung des Eriindun<scdankcns crgiht'sich dann, wenn man einen lxreits an anderer Stelle vorgeschl--tgenc°n Körper zur Konzentration der Feldlinien ! Biiodelungskörper i cenvendet. Diesr Iifindelungskörper besteht, wie :ins Fig. ,; und 4. zu ersehen ist, aus einem elektrisch gut leitenden, außen zylindrisch und imren kegelförmig ausgebildeten '1'c-il ;, der einen vorn r1u0rnrand lös zur Düsenbohrung verlaufenden Schlitz .l hat. Dieser Sehlltl .l kann mit einem beliebigen Isoliertoll' ausgefüllt sein.1? A particularly advantageous development of the invention It works when you propose a body elsewhere to concentrate the field lines! Biodelungskörper i used. This lead body consists as: in Fig.,; and 4. can be seen from an electrically good conductive, externally cylindrical and internally conical '1'c-il;, one in front r1u0rnrandlös slit running towards the nozzle bore .l. This Sehlltl .l can be filled in with any insulation requirement.
Dic wir den Bündclungsl;iirper angeordnete Induktorspule a erzeugt ün Bündelungskörpcr einem Stromverlauf, wie er in Fi#Z..1 mit dei-,Linie 5 angedeutet ist. Hierbei ergibt sich eine hesondure Konzentration bei 6 i Fig. 3,. so daft die Hauptheizleistung auf den Leiter r an der IVisenspitze auftritt. Der finit der lic° clfiirmigen Bohrung versehene Bündelungskörper dient auch hier deichzeitig M Luftführung.The inductor coil a, which is arranged in a bundle, generates a current curve in the bundling body, as indicated in Fig. Z..1 with the line 5. This results in a hesondure concentration at 6 i Fig. 3 ,. so that the main heating output occurs on conductor r at the tip of the tip. The bundling body, which is provided with the finely shaped bore, is also used here for air guidance.
