Description

Die Erfindung bezieht sich auf eine Vorrichtung zum radialen Verstellen des Düsenringes gegenüber dem fest und zentral im Spritzkopf einer Strangpresse angeordneten Dorn für die Herstellung von Schläuchen aus organischen, plastischen Kunststoffen. Die Düsenringe an den Spritzköpfen dieser Strangpressen werden üblicherweise mittels radial angebrachter Stellschrauben verstellt. Dabei kann jedoch die Einstellung nicht mit ausreichender Genauigkeit vorgenommen werden, auch wenn Stellschrauben mit Feingewinde verwendet werden. The invention relates to a device for radial adjustment of the nozzle ring opposite the fixed and central in the die head of an extrusion press arranged mandrel for the production of hoses from organic, plastic Plastics. The nozzle rings on the die heads of these extrusion presses are usually adjusted by means of radially attached adjusting screws. However, the setting not be made with sufficient accuracy, even if adjusting screws can be used with a fine thread.

Erfindungsgemäß sind daher am Umfang des Düsenringes mehrere Keile von im Spritzkopf eingesetzten und in der Schneckenachsrichtung der Strangpresse angeordneten Spannschrauben gehalten, unter deren Einwirkung die Keile einerseits gegen den Spritzkopf, andererseits gegen eine entsprechend konisch ausgebildete Außenfläche des am Spritzkopf sich abstützenden Düsenringes zur Anlage gelangen. In einer weiteren Ausführungsform wird der Düsenring kugelig ausgebildet und kann mit Hilfe von kugeligen Beilagscheiben radial zum Dorn verstellt werden. According to the invention there are therefore several wedges on the circumference of the nozzle ring of inserted in the die head and in the screw axis direction of the extruder arranged clamping screws held, under the action of the wedges on the one hand against the spray head, on the other hand against a correspondingly conical shape The outer surface of the nozzle ring supported on the spray head comes to rest. In a further embodiment, the nozzle ring is spherical and can can be adjusted radially to the mandrel with the aid of spherical washers.

Diese Bauart hat den Vorzug, daß der Düsenring gegenüber dem Dorn wesentllich feiner und damit genauer eingestellt werden kann. Außerdem kann ein Heizkörper, der auf den Düsenkörper aufgeschoben wird, ohne Entfernung der Stell schrauben wieder abgezogen werden. This design has the advantage that the nozzle ring over the mandrel can be set much finer and therefore more precise. In addition, a Radiator that is pushed onto the nozzle body without removing the actuator screws can be removed again.

Abb. I und 2 zeigt im Schnitt und in der Vorderansicht eine Düsenringverstellung, bei der der Düsenring 2 im Düsenkörper I auf einer sauber geschliffenen Fläche aufliegt; durch sechs konische, mit Schrauben 4 und Mutter 5 verstellbare Keil-oder Gleitstücke 3, die sich einerseits am Düsenkörper 1 und andererseits am Düsenring 2 abstützen, läßt sich der Ring in radialer Richtung gegen den Spritzdorn 6 leicht verstellen. Fig. I and 2 shows in section and in the front view a nozzle ring adjustment, in which the nozzle ring 2 in the nozzle body I rests on a cleanly ground surface; with six conical wedge or sliding pieces adjustable with screws 4 and nuts 5 3, which are supported on the one hand on the nozzle body 1 and on the other hand on the nozzle ring 2, the ring can be easily adjusted in the radial direction against the spray mandrel 6.

Abb. 3 und 4 zeigt in Schnitt und Vorderansicht eine Düsenringversteilung, bei der ein kugelförmig geschliffener Düsenring 2a vorgesehen ist. Dieser Ring kann am Düsenkörper 1 durch sechs Schrauben 4 und Mutter 5 mittels der verstellbaren kugeligen Beilagscheiben 3a radial zum Dorn 6 verstellt werden. Fig. 3 and 4 shows a sectional and front view of a nozzle ring distribution, in which a spherically ground nozzle ring 2a is provided. This ring can on the nozzle body 1 by six screws 4 and nut 5 by means of the adjustable spherical washers 3a can be adjusted radially to the mandrel 6.
