Description

Für die Herstellung von Hohlkörpern aus bildsamen keramischen Massen od. dgl. werden Strangpressen verwendet, in deren Mundstück eine Siebplatte angeordnet ist. Hierbei verläuft die Achse der Bohrungen der Siebplatte parallel zur Ziehrichtung. Beim Ziehen von größeren Hohlkörpern wurde der Nachteil festgestellt, daß Schichten- und Strukturbildungen auftreten, die durch die verschiedenartige Verdichtung der Masse nach dem Durchgang durch die Siebplatte hervorgerufen werden.For the production of hollow bodies from malleable ceramic masses Od. The like. Extrusion presses are used in the mouthpiece of which a sieve plate is arranged is. Here, the axis of the holes in the sieve plate runs parallel to the drawing direction. When drawing larger hollow bodies, the disadvantage was found that layered and structure formations occur due to the various types of compression of the Mass after passage through the sieve plate.

Gemäß der Erfindung werden diese Nachteile dadurch vermieden, daß die Bohrungen der Siebplatte in Richtung auf den im Mundstück angeordneten Kern geneigt ausgebildet sind. Hierdurch erfolgt eine bessere Durchmischung der :Masse, so daß ein gezogener Körper erreicht wird, der weitgehendst homogen ist. In den Fig. i und .2 ist die Erfindung schematisch an einem Ausführungsbeispiel dargestellt. In dem Mundstück i ist eine Siebplatte 2 angeordnet, deren Bohrungen 3 in Richtung auf den Kern 4 geneigt sind. Die Richtung für den Durchtritt der Masse ist durch die Pfeile 5 dargestellt. Die Neigung der Bohrungen beträgt etwa 2o°.According to the invention, these disadvantages are avoided in that the holes in the sieve plate in the direction of the core arranged in the mouthpiece are inclined. This results in a better mixing of the: mass, so that a drawn body is achieved which is largely homogeneous. In the Fig. I and .2 the invention is shown schematically in one embodiment. In the mouthpiece i a sieve plate 2 is arranged, the bores 3 in the direction are inclined on the core 4. The direction for the passage of the mass is through the arrows 5 shown. The inclination of the holes is about 2o °.
