Description
Mundstück für Strangpressen zur Herstellung allseitig geschlossener Höhlsteine Die Erfindung bezieht sich auf die Herstellung allseitig geschlossener Hohlsteine in einer Strangpresse, wobei ein Strang über die Kernstücke gepreßt und als Stirnseite zweier Ziegel in den hohlen Strang ein Lehmstück eingepreßt wird.Mouthpiece for extrusion presses for the production of closed on all sides Cave stones The invention relates to the production of all-round closed stones Hollow stones in an extruder, where a strand is pressed over the core pieces and A piece of clay is pressed into the hollow strand as the face of two bricks.
Gemäß der Erfindung ist im Innern des Mundstückes der Strangpresse durch eine Zwischenwand über den Kernen eine besondere Lehmkammer gebildet, vor welcher noch innerhalb des Mundstückes, und zwar vor der Austrittsöffnung desselben, durch einen hier gelagerten Kolben die Höhlungen im Ziegel, bevor dieser die Presse verläßt, durch die aus der Lehmkammer kommende Strangmasse verschlossen werden. Es erfolgt somit das Schließen der Höhlungen gleichzeitig mit dem Formen des Stranges durch einen senkrecht beweglichen Kolben innerhalb der Presse, so daß eine gleichmäßige Ziegelform gesichert ist, da hierbei der Ziegelstrang auf der glatten Unterlagsläche des Mundstückes gleitet und aufliegt.According to the invention, the extruder is inside the mouthpiece a special clay chamber was formed by a partition over the cores which is still inside the mouthpiece, in front of the outlet opening of the same, by means of a piston stored here, the cavities in the brick before the press leaves, are closed by the strand mass coming from the clay chamber. The cavities are thus closed at the same time as the strand is shaped by a vertically movable piston inside the press, so that a uniform The shape of the brick is secured, since the strand of bricks is on the smooth underlying surface of the mouthpiece slides and rests.
Die Einrichtung ist auf der Zeichnung in einem Ausführungsbeispiel im .Längsschnitt dargestellt.The device is on the drawing in one embodiment shown in longitudinal section.
Im Mundstück a der Presse sind die bekannten Kernstücke e gelagert, und es ist über diesen erfindungsgemäß eine Zwischenwand b eingebaut, wodurch eine besondere Lehmkammer c gebildet ist. In dieser Kammer c und vor den Kernstücken e bewegt sich in senkrechter Richtung ein Kolben d über der unteren Fläche des Mundstückes zwangsläufig mit der Abschneidvorrichtung g, so daß innerhalb der Presse nach jedem Strangvorschub vom Kolben d aus der Kammer c eine Lehmwand f in den Hohlstrang eingepreßt wird, welche die sonst offenen Höhlungen h des Stranges verschließt. Diese Wand ist dann in an sich bekannter Weise gleichzeitig die Trennwand zweier Hohlziegel.The known core pieces e are stored in the mouthpiece a of the press, and there is a partition b installed over this according to the invention, whereby a special clay chamber c is formed. In this chamber c and in front of the core pieces e a piston d moves in the vertical direction over the lower surface of the mouthpiece inevitably with the cutting device g, so that within the press after each Strand feed from piston d from chamber c presses a clay wall f into the hollow strand which closes the otherwise open cavities h of the strand. This wall is then, in a manner known per se, at the same time the dividing wall of two hollow bricks.
