Description

Vorrichtung zum Formen von Ringen und ähnlichen Gegenständen aus plastischer lasse Die Erfindung betrifft eine Vorrichtung zum Formen von Ringen und ähnlichen Gegenständen aus plastischer Masse, die das Formen in kontinuierlichem Betrieb ermöglicht und die Handarbeit auf ein Mindestmaß herabsetzt.Device for forming rings and similar objects from plastic The invention relates to an apparatus for forming rings and the like Objects made of plastic mass, which enable molding in continuous operation and reduces manual labor to a minimum.

Die Erfindung besteht darin, daß, der Kopf einer Strang presse mit Führungen versehen ist, durch die ein Kern mit auf ihm aufgesetzten Formringen derart durch den Pressenkopf hindurchgeführt werden kann, daß die Räume zwischen den Ringen mit der plastischen Masse angefüllt werden.The invention consists in that the head of an extruder press with Guides is provided through which a core with molded rings placed on it in such a way can be passed through the press head that the spaces between the rings be filled with the plastic mass.

In der Zeichnung ist ein Ausführungsbeispiel dargestellt.An exemplary embodiment is shown in the drawing.

Ringe i, die mit Rohransätzen 2 (Abb. 2) versehen sind, werden auf einen starren Kern 3, z. B. einen walzenförmigen Stab oder ein Rohr, aufgesetzt, wobei zwischen den Ringen i ringförmige Räume 4 entstehen. Der Kern mit den aufgesetzten Ringen i wird auf beliebige Weise, z. B. mit der Hand, durch den Hohlraum 5 des Kopfes 6 einer Strangpresse 8 hindurchgeführt, mit der er durch einen Flansch ; verbunden ist. Der Kopf 6 ist mit auswechselbaren Führungen 9 versehen, deren Mittelöffnungen genau den Ringen i oder sonstigen Formen entsprechen.Rings i, which are provided with pipe sockets 2 (Fig. 2), are on a rigid core 3, e.g. B. a cylindrical rod or a tube, put on, wherein between the rings i annular spaces 4 arise. The core with the attached Wrestling i is done in any way, e.g. B. by hand, through the cavity 5 of the The head 6 of an extruder 8 passed, with which he through a flange; connected is. The head 6 is provided with exchangeable guides 9, the central openings correspond exactly to the rings i or other shapes.

Die Vorrichtung wirkt folgendermaßen: Die in die Presse gefüllte plastische Masse wird, wie üblich, in der Richtung der Pfeile mit Hilfe eines Kolbens i i oder einer Schnecke vorwärts befördert, wodurch sie in den Hohlraum 5 hineingepreßt und unter einem bestimmten Druck erhalten wird. Die unter Druck stehende Masse füllt die freien ringförmigen Räume 4, gebildet durch die Ringe i, welche am Kern durch Muttern ifestgehalten werden (Abb. i), aus. Zum Zwecke der Versteifung der aus der plastischen Masse zu erzeugenden Ringe können in den Räumen zwischen den Ringen i Drahtstücke oder ähnliche Verstärkungen angebracht werden.The device works as follows: The plastic one filled into the press Mass is, as usual, in the direction of the arrows with the help of a piston i i or a screw conveyed forward, whereby it is pressed into the cavity 5 and is obtained under a certain pressure. The pressurized mass fills the free annular spaces 4, formed by the rings i, which on the core through Nuts are held in place (Fig. I). For the purpose of stiffening the from the Plastic mass to be produced rings can be in the spaces between the rings i pieces of wire or similar reinforcements are attached.

Die in den Zwischenräumen 4 erzeugten Ringe lassen sich nach Abschrauben der Mutter 12 ohne Schwierigkeit nacheinander herunternehmen und unter der Presse zusammenpressen oder bei Herstellung von Kautschukringen mit dem Rohr 3 und den Ringen i vulkanisieren.The rings generated in the spaces 4 can be removed after unscrewing take the mother 12 down one after the other without difficulty and under the press compress or when producing rubber rings with the tube 3 and the Rings i vulcanize.

Durch Änderung der Höhe des Ansatzes 2, der Abmessungen sowie der Gestalt der Ringei und der Führungen 9 können Ringe beliebiger Größe und Gestalt erzeugt werden.By changing the height of the approach 2, the dimensions and the Shape of the ring egg and the guides 9 can rings of any size and shape be generated.
