Description

Bekannt ist, daß zür Metallisierung von Hohlräumen, Röhren usw. mit den bekannten Metallspritzpistolen rotierende Winkeldüsen von etwa 8o', u. a. mit Düsenverlängeru.ngen, in Anwendung sind. Der starr abgeleitete Zerstäubungsstrahl ist je nach Konstruktion im Bereich von o bis 8o' unveränderlich. Die vorliegende Erfindung soll jedoch über diese Möglichkeiten hinaus eine Ableitung des Zerstäubungsstrahls bis zu i2o', und zwar während des Betriebes beliebig verstellbar von o bis i:2o' gestatten. Damit könnte von einem festen Punkt aus, ohne die Spritzpistole zu bewegen, z. B. eine Hohlkugel zu 3/4 ihrer Innenfläche metallisiert werden. Anders ausgedrückt, kann man also um etwa 3o' rückwärts spritzen.It is known that for the metallization of cavities, tubes etc. with the known metal spray guns, rotating angled nozzles of about 8o ', including nozzle extensions, are used. The rigidly deflected atomization jet is unchangeable in the range from 0 to 8o ' , depending on the design. In addition to these possibilities, however, the present invention is intended to allow the atomizing jet to be diverted up to i2o ', to be precise adjustable from 0 to i: 2o' during operation. This could be from a fixed point without moving the spray gun, for. B. a hollow sphere can be metallized to 3/4 of its inner surface. In other words, you can inject about 3o 'backwards.

Mit dieser Düse erreicht man ferner eine bessere Zerstäubung des Materials und damit eine größere Dichte und Haftfähigkeit des überzugs.With this nozzle one also achieves better atomization of the material and thus a greater density and adhesion of the coating.

Durch die vermehrte Zuführung von kalter Zerstäubungsluft oder Gas wird die Temperatur der Schmelzflamme wesentlich herabgesetzt. Damit wird gleichzeitig eine Kühlung des Gegenstandes,-auf den das Spritzmaterial aufgetragen wird, erreicht. Die Veränderung des Ablenkungswinleels des Spritzstrahls erfolgt durch entsprechende Regulierung der Preßluftzufuhr zur Winkeldüse. In der Zeichnung ist sc:fieniatisch die Anordnung einer solchen Zerstäubungswinkeldüse dargestellt. Die Düsenverlängerung A mit konzentriscb angeordneter Drahtdüse i, Gasgemischdüse 2 zum Abschm,elzen des Drahtes und Zerstäubungspreßluftdüse 3 spritzt in gerader Richtung. Durch Zuleitung weiterer Preßluft oder Gase durch das Rohr B über die abgewinkelte Düse C wird der Spritzstrahl je nach Stärke des durch Ventil a regulierten Preßluftstrahls aus seiner ursprünglichen Richtung von I-II abgelenkt. Läßt man das Rohr B allein oder mit der Zerstäubungsluftdüse 3 rotieren, kann eine Kugelinnenfläche, wie eingangs geschildert, gespritzt werden; die durch die Zerstäubungsdüse 3 zerstäubten Metalle werden durch die zusätzliche Preßluft aus der Winkeldüse- c weiterzerstäubt, womit ein feineres Spritzkorn sowie eine größere Dichte und Haftfähigkeit erzielt werden. Die durch die Winkeldüse c austretende Preßluft setzt die Temperatur der Schmelzgase nach der Schmelzarbeit wesentlich herab und ergibt somit auch eine Kühlung der zu bearbeitenden Teile.The increased supply of cold atomizing air or gas significantly reduces the temperature of the melting flame. In this way, the object to which the spray material is applied is cooled at the same time. The angle of deflection of the spray jet is changed by regulating the compressed air supply to the angled nozzle accordingly. In the drawing, the arrangement of such an atomizing angle nozzle is shown in a fieniatic manner. The nozzle extension A with a concentrically arranged wire nozzle i, gas mixture nozzle 2 for melting the wire and atomizing press air nozzle 3 sprays in a straight direction. By supplying further compressed air or gases through the pipe B via the angled nozzle C , the spray jet is deflected from its original direction from I-II depending on the strength of the compressed air jet regulated by valve a. If the tube B is allowed to rotate alone or with the atomizing air nozzle 3 , an inner spherical surface can be sprayed, as described above; the metals atomized by the atomizing nozzle 3 are further atomized by the additional compressed air from the angled nozzle, which results in a finer spray grain as well as greater density and adhesion. The compressed air exiting through the angled nozzle c significantly lowers the temperature of the melting gases after the melting work and thus also results in a cooling of the parts to be processed.
