Die Neuerung betrifft Rohrdüsenköpfe für Kunststoff-Strangpressen, welche mit dem Austritt des Strangpressen-Zylinders verbundenes Gehäuse und einen in diesem konzentrisch gelagerten Dorn aufweisen.The innovation concerns pipe nozzle heads for plastic extrusion presses, which have a housing connected to the outlet of the extrusion cylinder and a mandrel mounted concentrically in this.
Die verschiedenen zu verarbeitenden Thermoplaste besitzen auch verschiedene Viskositäten. Der Flußkanal muß Jeweils der bestimmten Viskosität entsprechend ausgelegt werden. So sieht beispielsweise ein Flußkanal in einer Rohrdüse für Polyolefine anders aus als der entsprechende Kanal in einer Düse zur Verarbeitung von Hart-Polyvinylchlorid. Auch für die verschiedenen Wandstärken der auszubringenden Rohre sind jeweils verschiedene Austrittsquerschnitte und verschiedener Querschnittsaufbau der Düse erforderlich.The different thermoplastics to be processed also have different ones Viscosities. The flow channel must be designed according to the particular viscosity. This is how it looks, for example a flow channel in a pipe nozzle for polyolefins is different from the corresponding channel in a nozzle for processing rigid polyvinyl chloride. There are also different outlet cross-sections and for the different wall thicknesses of the pipes to be discharged different cross-sectional structure of the nozzle required.
Durch die vorliegende Neuerung soll ein Rohrdüsenkopf geschaffen werden, in welchem durch Wechselelemente jeweils die gewünschten Bedingungen und Wandstärken für den gerade zu bearbeitenden Kunststoff zu schaffen sind. Der Düsenkopf kann dann universell für die verschiedensten Materialien Verwendung finden. Es liegt dabei die Aufgabe zugrunde, die genannten Wechselelemente in solcher Weise im Düsenkopf vorzusehen, daß ihre Befestigung einfach und sicher ist, so daß weder nennenswerte Zeitverluste noch Fehler bei der Herstellung der Kunststoffrohre durch die Wechselelemente auftreten können.The present innovation is intended to create a pipe nozzle head in which the desired Conditions and wall thicknesses are to be created for the plastic to be processed. The nozzle head can then be used universally for the various materials are used. It is based on the task of changing the elements mentioned in such a way To provide nozzle head that their attachment is simple and secure, so that neither significant loss of time nor errors in manufacture the plastic pipes can occur through the interchangeable elements.
Die Neuerung zeichnet sich dadurch aus, daß der Mantel des Dornes gänzlich oder teilweise durch eine Vielzahl untereinander austauschbarer, dicht aneinanderliegender und zwischen einem Bund des Dornes und einem stirnseitigen Klemmring am Dorn gehaltener Ringe gebildet ist.The innovation is characterized by the fact that the jacket of the thorn wholly or partially by a large number of interchangeable, closely spaced and between a collar of the mandrel and an end clamping ring is formed on the mandrel held rings is.
In der Zeichnung ist ein Ausführungsbeispiel der Neuerung vereinfachtAn exemplary embodiment of the innovation is simplified in the drawing

dargestellt. In dem Austritt des Strangpressen-Zylinders 2 ist die Schnecke 1 erkennbar, von der aus das Material in den Flußkanal 6 des Sohrdüsenkopfes 3 tritt. Mit 4 ist der konzentrisch gelagerte Dorn im Düsenkopf bezeichnet. Di® untereinander austauschbaren Ringe 7. 8, 9 sind zwischen einem Bund des Dornes 4 und eine» stirnseitig auf dem Dorn angebrachten Klemmring 5 festgehalten.shown. In the exit of the extrusion cylinder 2 is the A screw 1 can be seen from which the material enters the flow channel 6 of the nozzle head 3. With 4 is the concentrically mounted Marked mandrel in the nozzle head. Di® interchangeable rings 7. 8, 9 are between a collar of the mandrel 4 and a »end face on the mandrel attached clamping ring 5 held.
Im vorliegenden Fall finden Binge verschiedener Form und Größe Verwendung. Die Ringe 9 und 8 bilden dabei eise Staustelle mit rheologisch vorteilhaft ausgeführten übergängen auf die Durchmesser der Ringe 7. Die Ringe können gänzlich verschiedene Formen und Größen aufweisen.In the present case, bings of various shapes and sizes are used. The rings 9 and 8 form ice stagnation points with rheologically advantageous transitions to the diameter of the Rings 7. The rings can be of entirely different shapes and sizes exhibit.
Durch die dargestellte Anbringung der Einge auf dem Dorn wird ein gutes Änelnanderliegen derselben erreicht. Zusätzliche Bohrungen und andere Vorkehrungen am Düsenkopf, welche einer Befestigung der Ringe dienen sollen, sind dadurch außerdem vermieden.By attaching the singles to the mandrel shown, a good alignment of the same achieved. Additional holes and other provisions on the nozzle head, which a fastening of the Rings are intended to serve, are also avoided.
