Abstract
Description
Mit einer solchen Ausbildung des Preßw^rkzeuges wird erreicht, daß die den Formraum begrenzende Funktion des verschleißanfälligen Metallmantels beim Preßvorgang durch die in der Ringkammer anstehende keramische Masse übernommen wird. Damit wird der Verschleiß reduziert and daraus folgt dann, daß einWith such a design of the press tool it is achieved that the function of the wear-prone metal shell limiting the mold space Pressing process is taken over by the pending ceramic mass in the annular chamber. This becomes the Reduced wear and it then follows that a
js Nacharbeiten der Ränder des Preßteils entfallen kann.js reworking the edges of the pressed part can be omitted.
Aus der DE-OS 26 57 993 ist zwar eine während des Einfüllvorganges des Keramikmaterials den Formraum umgebende Ringkammer vorgesehen. Diese wird jedoch vor dem Verpressen des Materials weggefahreii und durch einen über den Ringspalt verschobenen Mantel ersetzt so daß sich dort ähnliche nachteilige Verhältnisse ergeben, wie bei dem Preßwerkzeug, von dem bei der Erfindung ausgegangen wird.From DE-OS 26 57 993 it is true that one during the filling process of the ceramic material is the mold space surrounding annular chamber provided. However, this is removed before the material is pressed and replaced by a jacket displaced over the annular gap so that there are similar disadvantageous conditions result, as in the pressing tool, from which the invention is based.
Bei einer Weiterbildung der Erfindung ist der Ab-Schluß der Ringkammer an deren den Ringspalt überstreifenden
Seite elastisch ausgebildet
Die Zeichnung zeigt inIn a further development of the invention, the closure of the annular chamber is designed to be elastic on its side which straddles the annular gap

Fig.5 die Entnahme des fertigen Preßkörpers aus dem Werkzeug.5 shows the removal of the finished compact from the tool.
Das in den Figuren wiedergegebene Preßwerkzeug dient zur Herstellung von Tellern aus pulverförmiger keramischer Masse. Das Preßwe^kzeug enthält einen Stempel 10, einen Gegenstempel 11 und einen den Stempel 10 umgebenden Mantel !2, der auf dem Stempel verschiebbar ist.The pressing tool shown in the figures is used to produce plates from powdery ceramic mass. The Preßwe ^ kzeug contains a punch 10, a counter punch 11 and a Stamp 10 surrounding jacket! 2, which is displaceable on the stamp.
Beim wiedergegebenen Ausführungsbeispiel weist der Stempel 10 einen kleineren Durchmesser als der Gegenstempel 11 auf. Der Mantel 12 besteht aus einem Ringkörper mit einer zylindrischen Führungsöffnung mit einem Durchmesser, der geringfügig größer als der Durchmesser des Stempels 10 ist. In die Innenfläche des Mantels 12 ist ein« Ringkammer 13 mit rechteckigem Querschnitt eingearbeitet. Diese Ringkammer 13 kann über eine radiale Zuführungsöffnung 14 mit einem nicht gezeichneten Vorratsbehälter für das pulverförmige keramische Preßgut verbunden sein. Die Ringkammer 13 ist an der dem Gegenstempel 11 zugewandten Seite durch einen biegsamen Ring 15 aus elastischem Gummi oder einem ähnlichen entsprechenden Material abgeschlossen. Dieser Ring kann sich bei der Verschiebung des Mantels 12 in Richtung auf den Gegenstempel 11 beim Auftreffen auf dem Gegenstempe! verformen, indem er sich teilweise über den abgerundeten Rand dieses Gegenstempels legt, wie die Fig.2 und 3 deutlich erkennen lassen. Ein ringförmiger Belag 16 aus elastischem Gummi oder Filz sitzt in einer entsprechenden Rinne im Mantel 12 und begrenzt den Austritt keramisehen Pulvers.In the illustrated embodiment, the punch 10 has a smaller diameter than that Counter stamp 11 on. The jacket 12 consists of a Annular body with a cylindrical guide opening with a diameter slightly larger than that Diameter of the punch 10 is. In the inner surface of the Jacket 12 is incorporated an "annular chamber 13 with a rectangular cross-section. This annular chamber 13 can Via a radial feed opening 14 with a storage container (not shown) for the powdery ceramic Be compacted connected. The annular chamber 13 is on the side facing the counter punch 11 terminated by a flexible ring 15 made of elastic rubber or a similar corresponding material. This ring can move when the jacket 12 is moved in the direction of the counter punch 11 when hitting the counterstempe! deform by it lies partially over the rounded edge of this counter-punch, as clearly shown in FIGS reveal. An annular covering 16 made of elastic rubber or felt is seated in a corresponding one Groove in the jacket 12 and limits the exit of ceramic powder.
Die Stirnseite des Stempels 10 formt die Oberseite des Tellers aus und ist mit einer dicken elastischen Gummiplatte 19 bedeckt, die selbstreinigend v/irkt und in derThe face of the stamp 10 forms the top of the plate and is covered with a thick elastic rubber plate 19 covered, the self-cleaning v / irkt and in the
Nähe des Randes ringförmig vorsteht, wie man bei 20 erkennt. Dadurch ergibt sich an den Preßkörpern ein abgerundeter Rand, der keine oder nur noch geringe Nacharbeitung erforderlich macht.Near the edge protrudes in a ring, as shown at 20 recognizes. This results in a rounded edge on the pressed bodies, which has little or no Makes reworking necessary.
Die Stirnseite des Gegenstempels 11 ist entsprechend der Unterseite des Tellers beim wiedergegebenen Ausführungsbeispiel ausgeformt und weist eine starke Abfasung zur zylindrischen Fläche hin auf. Auch sie ist mit einer elastischen Gummiplatte 22 bedeckt Der kreisförmige Rand der Platte ist im spitzen Winkel gebogen und hat einen umgestülpten Rand, der zwischen zwei kegelstumpfförmigen Blöcken 23 und 24 gehalten ist, die ineinandergeschoben und durch Schrauben miteinander verbunden werden.The face of the counter punch 11 is corresponding the underside of the plate in the illustrated embodiment shaped and has a strong chamfer towards the cylindrical surface. She is also with an elastic rubber plate 22 covered. The circular edge of the plate is bent at an acute angle and has an everted edge that is between two frustoconical Blocks 23 and 24 are held, which are nested and screwed together get connected.
Der Block 23 ist in seinem Mittelteil mit mehreren Leitungen versehen, die die Verbindung zwischen der Stirnseite des Blockes 23 und einer Kammer 26 herstellen, in die Druckmittel eingeführt wird. Dadurch löst sich die Platte 22 vom Block 23 und drückt gegen die vorverdichtete keramische Pulvermasse, wodurch der Preßvorgang hydrostatisch beendet wird.The block 23 is provided in its central part with several lines that the connection between the Produce the end face of the block 23 and a chamber 26 into which pressure medium is introduced. This triggers the plate 22 from the block 23 and presses against the pre-compressed ceramic powder mass, whereby the Pressing process is ended hydrostatically.
F i g. 5 zeigt die Trennung von Stempel und Gegenstempel und damit die Freigabe des fertigen Preßkörpers. F i g. 5 shows the separation of stamp and counter stamp and thus the release of the finished compact.
