Description
stets eine Druckspannung aufrechterhalten wird. Dadurch kann die Matrize aus einem sehr harten und abnutzungsfesten keramischen Material, wie Aluminiumoxyd, hergestellt werden, trotz der Tatsache, daß ein solches Material keine hohen Zugspannungen aushalten kann. Dadurch, daß sämtliche Zylinder der Druckglieder 4 an dieselbe Druckflüssigkeitsquelle angeschlossen werden, kann auf einfache Weise gleicher Druck auf jede Seitenfläche der Matrize erzielt werden. Die Ausführung der Druckglieder kann auch von der der oben beschriebenen Druckglieder verschieden sein. Statt aus einem unter Druck einer Flüssigkeit in einem Zylinder beweglichen Kolben können die Druckglieder aus einem nicht dargestellten, in einer Führung beweglichen Stab bestehen, mit dem ein Druckbolzen verbunden ist. Federnde Elemente, z. B. in Form von^ Tellerfedern, wirken auf den Stab ein und können mit Hilfe einer einstellbaren Schraube unter Spannung gebracht werden. Der Druck auf jede der Seitenflächen 2 der Matrize kann dann unabhängig eingestellt werden.a compressive stress is always maintained. This can make the die from a very hard and wear-resistant ceramic material, such as alumina, can be produced, despite the fact that such a material cannot withstand high tensile stresses. The fact that all cylinders of the Pressure members 4 are connected to the same pressure fluid source, can be the same in a simple manner Pressure can be achieved on each side surface of the die. The execution of the pressure members can also be of the the compression members described above may be different. Instead of a pressurized liquid in one Cylinder movable piston can push members from a not shown, in a guide exist movable rod with which a pressure pin is connected. Resilient elements, e.g. B. in the form of ^ Disc springs act on the rod and can be under tension with the help of an adjustable screw to be brought. The pressure on each of the side surfaces 2 of the die can then be adjusted independently.
Ein Heizelement für die Matrize kann z. B. aus einerA heating element for the die can e.g. B. from a
ίο Heizwendel bestehen, die in einer Nut 9 in der Außenoberfläche der Matrize angebracht ist.ίο There are heating coils in a groove 9 in the External surface of the die is attached.
