Düsenkopf für Blasdorne von Vorrichtungen zum HohlkörperblasenNozzle head for mandrels of devices for blowing hollow bodies
Die Erfindung betrifft einen Düsenkopf für Blasdorne von Vorrichtungen zum Hohlkörperblasen, insbesondere Düsenköpfe für die Zufuhr von tiefkalten, verflüssigten Gasen.The invention relates to a nozzle head for blow pins of devices for blowing hollow bodies, in particular nozzle heads for the supply of cryogenic, liquefied Gases.
Bisher bestehen solche Düsenköpfe in der Regel aus einem kleinen topfförmigen Körper, dessen Inneres gasdicht mit einem Rohr verbunden ist, das auswechselbar mit dem im · Inneren des Blasdornkörpers vorgesehenen Austritt, für das gasförmige oder flüssige Blasmittel verbunden ist. Der Boden solcher Düsenköpfe weist eine feine Austrittsbohrung auf. Diese Bohrung liegt entweder in der Mitte des Bodens und ist koaxial zur Achse des Düsenkopfes. In manchen Fällen jedoch liegt sie im Hinblick auf gewünschte Effekte in einem bestimmten Winkel zur Achse des Düsenkopfes. In solchen Fällen ist es häufig schwierig, diesen Winkel richt'ig zu bestimmen, so daß es in der Regel notwendig wird, zwecks Erprobung der richtigen Lage mehrere solcher Düsen herzustellen. ■■So far, such nozzle heads have usually consisted of a small cup-shaped body, the interior of which is gas-tight is connected to a tube which is interchangeable with the outlet provided in the interior of the blow pin body, for which gaseous or liquid blowing agent is connected. The bottom of such nozzle heads has a fine outlet hole on. This hole is either in the middle of the base and is coaxial with the axis of the nozzle head. In some In some cases, however, in view of the desired effects, it lies at a certain angle to the axis of the nozzle head. In in such cases it is often difficult to determine this angle correctly, so that it is usually necessary will produce several such nozzles in order to test the correct position. ■■

Aufgabe der Erfindung ist es, den Düsenkopf für Blasdorne dahin zu verbessern, daß solche zusätzlichen Arbeiten vermieden werden können.The object of the invention is to improve the nozzle head for blow pins so that such additional Work can be avoided.
Gemäß der Erfindung besteht der Düsenkopf aus einem Kapillarröhrchen, dessen eines Ende mit einem mit dem Gasaustritt des Blasdornkörpers lösbar befestigten Verbindungsstück gasdicht verbunden ist und dessen anderes Ende mindestens bis in die Blasmündung des Blasdorns reicht. Dies Auslaßende des Kapillarröhrchens läßt sich leicht in jede gewünschte Richtung biegen. Statt eines solchen Kapillarröhrchens können mehrere Kapillarröhrchen nebeneinander oder vorzugsweise parallel zueinander angeordnet sein.According to the invention, the nozzle head consists of a capillary tube, one end of which with a Gas outlet of the blow pin body is releasably attached connecting piece is connected gas-tight and the other The end reaches at least into the mouth of the blow pin. This outlet end of the capillary tube can be bend easily in any direction you want. Instead of such a capillary tube, several capillary tubes can be used be arranged next to one another or preferably parallel to one another.
Die Zeichnung zeigt AusführungsbeispMe der Erfindung.The drawing shows embodiments of the invention.
Fig. 1 zeigt einen Längsschnitt durch einen Blasdorn mit ehern Düsenkopf gemäß der Erfindung.Fig. 1 shows a longitudinal section through a blow pin with an iron nozzle head according to the invention.
Fig. 2 zeigt einen Schnitt nach Linie II - II der Fig. 1.FIG. 2 shows a section along line II-II of FIG. 1.
Fig. 3 zeigt ebenfalls einen Querschnitt durch einen Blasdorn mit einem Düsenkopf gemäß der Erfindung.Fig. 3 also shows a cross section through one Blow mandrel with a nozzle head according to the invention.
Der dargestellte Blasdorn besitzt einen Blasdornkörper 1, der in seinem vorderen Teil einen zylindrischen Hohlraum aufweist, der von einem Mantel 3 begrenzt ist, der in seinem vorderen Ende 3a eingezogen ist und dort eine öffnung 4 aufweist. An den zylindrischen Raum 2 schließt sich nach hinten ein zylindrischer Raum 6 an, in den eine Bohrung 5 mündet, die andererseits mit einer EinlaßleitungThe blow pin shown has a blow pin body 1, which has in its front part a cylindrical cavity which is delimited by a jacket 3, which in its front end 3a is retracted and there a Has opening 4. Closes to the cylindrical space 2 to the rear a cylindrical space 6, into which a bore 5 opens, which on the other hand with an inlet line

für das gasförmige oder flüssige Blasmedium verbunden ist. In den Hohlraum 6, in dem dies Blasmedium eintritt, ist ein Stück 7 eingeschraubt, in das das hintere Ende 8a eines Kapillarröhrchens 8 eingelötet ist. Das vordere Ende 8b des Kapillarröhrchens 8 ragt bis in die Mündung des vorderen Endes 3a des Blasdorns 1.for the gaseous or liquid blowing medium is connected. In the cavity 6, in which this blowing medium enters, a piece 7 is screwed into which the rear end 8a a capillary tube 8 is soldered. The front end 8b of the capillary tube 8 protrudes into the mouth of the front end 3a of the blow pin 1.
Die Steifigkeit des Kapillarröhrchens ist so groß, daß es axial, koaxial, freitragend oder auch spiralförmig im Blasdorn angeordnet sein kann. Sein vorderes Ende kann ohne Schwierigkeit in beliebigen Winkeln abgebogen werden. Es kann die öffnung 4 gegebenenfalls überragen und auch abgeschrägt sein.The rigidity of the capillary tube is so great that it is axial, coaxial, self-supporting or even spiral can be arranged in the blow pin. Its front end can be bent at any angle without difficulty. It may and may also protrude beyond the opening 4 be beveled.
Statt eines Kapillarröhrchens können mehrere Kapillarröhrchen in das Verbindungsstück 7 eingelötet werden. Fig. 3 zeigt eine Anordnung von sieben Kapillarröhrchen 8, 81. Die vorderen Enden dieser Kapillarröhrchen können in verschiedenen Richtungen abgebogen werden, beispielsweise derart, daß ein Teil der Kapillarröhrchen auf verschiedene Stellen des Bodens des zu blasenden Hohlkörpers und die übrigen Kapillarröhrchen auf verschiedene Stellen der Wandung dieses Hohlkörpers gerichtet sind.Instead of one capillary tube, several capillary tubes can be soldered into the connecting piece 7. 3 shows an arrangement of seven capillary tubes 8, 8 1 . The front ends of these capillary tubes can be bent in different directions, for example in such a way that some of the capillary tubes are directed at different points on the bottom of the hollow body to be blown and the remaining capillary tubes are directed at different points on the wall of this hollow body.
