Description

Spritzgutdüse mit einstellbarer Austrittsöffnung Gegenstand der Erfindung ist eine Spritzgutdüse mit einstellbarer Austrittsöffnung.Spray material nozzle with adjustable outlet opening is the subject of the invention is a spray material nozzle with an adjustable outlet opening.

Es sind Düsen bekannt, deren Austrittsöffnung durch Anordnung eines kegeligen Düsenkörpers und eines darüber in Achsenrichtung verstellbaren Mantelkörpers einstellbar ist. Solche Vorrichtungen lassen sich nur durch Auseinandernehmen reinigen. Dieser Nachteil wird durch den Gegenstand der Erfindung dadurch. vermieden, daß der Düsenkörper in seiner Achsenrichtung gegen den Druck einer Feder nach hinten bewegt werden kann, ohne daß es nötig ist, die Düse auseinanderzunehmen.There are nozzles known, the outlet opening by the arrangement of a conical nozzle body and a casing body adjustable in the axial direction is adjustable. Such devices can only be cleaned by disassembling them. This disadvantage is thereby made by the subject matter of the invention. avoided that the nozzle body in its axial direction against the pressure of a spring backwards can be moved without the need to disassemble the nozzle.

Außerdem kann die Austrittsöffnung mit Hilfe einer Verschraubung beliebig groß eingestellt werden.In addition, the outlet opening can be made as desired with the aid of a screw connection can be set large.

Eine solche verstellbare Spritzgutdüse hat den Vorzug, daß ihre Öffnung zu Reinigungszwecken durchstoßen werden kann.Such an adjustable spray material nozzle has the advantage that its opening can be pierced for cleaning purposes.

In der Zeichnung ist der Gegenstand der Erfindung in einem Ausführungsbeispiel im Längsschnitt dargestellt.In the drawing, the subject of the invention is in one embodiment shown in longitudinal section.

Eine -vorn kegelig zugespitzte, mit einer axialen Bohrung c und einer Querbohrung d versehene Düsennadel a ist in einer Buchse b mittels Gewindes axial verstellbar gelagert. Ein Querschnitt e zum Ansetzen eines Schraubenziehers dient zur Ausübung der Schraubbewegung. Die Buchse b wird durch eine Druckfeder t aus ihren vorderen Anschlag in einen Spritzgutdüsenkörpär g gedrückt. Eine in den Körper g geschraubte hohlzylindrische Buchse f dient dabei als hintere Auflage für die Feder t. Diese Buchse ist mit einem Einschnitt d für den Schraubenzieher versehen. Das Spritzgut tritt von hinten in die Bohrung der Düsennadel a ein, strömt durch die Querbohrungen d weiter und durch den konischen Ringspalt aus, der von der Düsennadel und dem Düsenkörper gebildet ist. Dieser Ringspalt läßt sich durch Vor- und Zurückschrauben der Düsennadel verengen bzw. erweitern. Soll die Düsenöffnung durchstoßen werden, so wird von vorn auf die Düsennadel gedrückt. Alsdann bewegt sich die Düsennadel mit ihrer Schraubbuchse b nach hinten in Richtung des Pfeiles k. Sie wird von der Feder t in ihre Ausgangsstellung zurückbewegt, sobald der Druck aufgehoben ist. Der. Spritzgutdüsenkörper g ist von einem Düsenkörper h umgeben, der mit dem Düsenkörper einen zylindrischen Ringkanal bildet und das Druckmittel durch einen kegelförmigen Ringspalt l zur Zerstäubungsstelle ausströmen läßt, wie es z. B. bei pneumatischen Farbspritzpistolen üblich ist. A nozzle needle a, which is conically pointed at the front and provided with an axial bore c and a transverse bore d, is mounted in an axially adjustable manner in a bushing b by means of a thread. A cross section e for applying a screwdriver is used to exercise the screwing movement. The socket b is pressed by a compression spring t out of its front stop into a spray material nozzle body g. A hollow cylindrical bushing f screwed into the body g serves as a rear support for the spring t. This socket is provided with a notch d for the screwdriver. The spray material enters the bore of the nozzle needle a from behind, flows on through the transverse bores d and out through the conical annular gap formed by the nozzle needle and the nozzle body. This annular gap can be narrowed or widened by screwing the nozzle needle back and forth. If the nozzle opening is to be pierced, the nozzle needle is pressed from the front. The nozzle needle then moves with its screw bushing b backwards in the direction of arrow k. It is moved back to its original position by the spring t as soon as the pressure is released. Of the. Spray material nozzle body g is surrounded by a nozzle body h which forms a cylindrical annular channel with the nozzle body and allows the pressure medium to flow out through a conical annular gap l to the atomization point, as it is, for. B. is common with pneumatic paint spray guns.
