Description
Die Erfindung bezieht sich auf eine Vorrichtung zur Befestigung einer Matrize an einer Kammer einer Strangpresse zum stirnseitigen Extrudieren von keramischem Material gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for fastening a die on a chamber of an extrusion press for end extrusion of ceramic material according to the Preamble of claim 1.
Aus der Druckschrift US-PS-3 900 546 ist eine Vorrichtung zur Befestigung einer Matrize gemäß dem Oberbegriff des Patentanspruchs 1 bekannt. Bei dieser bekannten Vorrichtung wird die Matrize mittels eines Ringstücks an einem Kammerkörper gehalten. Die Extrusionskammer hat einen trichterfömigen Einlauf, an dessen Öffnung die mit einem Sieb versehene Matrize angebracht ist. Die Matrize ist dabei in ihrem Umfangsbereich am Einlauf abgestützt.From the document US-PS-3 900 546 is a device for Attachment of a die according to the preamble of Claim 1 known. In this known device the die is attached to a chamber body by means of a ring piece held. The extrusion chamber has a funnel-shaped one Inlet, at the opening of which the matrix provided with a sieve is appropriate. The die is in its peripheral area supported at the inlet.
Aufgabe der Erfindung ist es, eine Vorrichtung zur Befestigung einer Matrize an einer Kammer einer Strangpresse zu schaffen, bei der die Gefahr einer Verformung oder Zerstörung der Matrize bei hoher Druckbelastung vermindert ist.The object of the invention is a device for fastening to create a die on a chamber of an extrusion press, where there is a risk of the die being deformed or destroyed is reduced at high pressure loads.
Diese Aufgabe wird durch die Kombination der im Patentanspruch 1 definierten Merkmale gelöst. Gemäß den im kennzeichnenden Teil des Patentanspruchs definierten Merkmale ist in der Kammer ein zylinderförmiges Einlaufelement mit einem sich axial erstreckenden Abschnitt bzw. Vorsprung vorgesehen. Das Einlaufelement stützt sich stirnseitig an der Innenfläche der Matrize ab, wobei der Mittelabschnitt der Matrize am axialen Abschnitt des Einlaufelementes befestigt ist. Die dadurch zustandekommende Verbindung zwischen Matrize und Einlaufelement gewährleistet ein solches Einspannen der Matrize, das die Gefahr einer Verformung und Zerstörung der Matrize bei hohen Druckbelastungen weitgehend beseitigt.This object is achieved by the combination of the claims 1 defined characteristics solved. According to the in the characteristic Features defined in the claim is in the chamber a cylindrical inlet element with an axially extending portion or projection provided. The Inlet element is supported on the face of the inner surface of the Die, with the central section of the die on the axial Section of the inlet element is attached. The result Established connection between the die and the inlet element ensures such a clamping of the die that the Danger of deformation and destruction of the die at high Pressure loads largely eliminated.
Die Erfindung wird im folgenden anhand eines Ausführungsbeispiels unter Bezugnahme auf Zeichnungen näher erläutert.The invention is based on a Exemplary embodiment with reference to drawings explained.

Fig. 1 eine Vorderansicht der Befestigungsvorrichtung für eine Extrusionsmatrize; und Fig. 1 is a front view of the fastening device for an extrusion die; and
Fig. 2 eine Schnittansicht der Befestigungsvorrichtung in Fig. 1 entlang der Linie A-A. Fig. 2 is a sectional view of the fastening device in Fig. 1 along the line AA.
Die Befestigungsvorrichtung in Fig. 1 hat eine gelochte Matrize 1, die entlang ihres Umfangs zwischen einem Flansch 2 einer Extrusionskammer und einem Ansatzstück 3 durch Schrauben 4 fest angebracht bzw. positioniert ist. Die Matrize 1 ist des weiteren in ihrem Mittelpunkt durch eine Mittelschraube 6 an einem Vorsprung eines Einlaufelements 5 befestigt. Das Einlaufelement 5 ist entlang seines ganzen Umfangs an der Innenseite der Matrize abgestützt.The fastening device in FIG. 1 has a perforated die 1 , which is fixedly attached or positioned along its circumference between a flange 2 of an extrusion chamber and an extension piece 3 by means of screws 4 . The die 1 is also fixed at its center by a central screw 6 to a projection of an inlet element 5 . The inlet element 5 is supported along its entire circumference on the inside of the die.
Die feste Anbringung der Matrize entlang ihres Umfangs zwischen dem Ansatzstück 3 und dem Kammerflansch 2 sowie die Befestigung der Matrize 1 an dem Vorsprung des Einlaufelements 5 durch die Mittelschraube 6 ermöglichen das Erreichen einer einwandfreien Befestigung der Matrize 1 in den Befestigungsabschnitten ohne einen Zwischenraum sowie eine vorteilhaftere Spannungsverteilung im Arbeitsbereich der Matrize 1 im Fall einer großen Belastung.The fixed attachment of the die along its circumference between the extension piece 3 and the chamber flange 2 and the attachment of the die 1 to the projection of the inlet element 5 by means of the central screw 6 enable the die 1 to be securely attached in the attachment sections without a space and a more advantageous one Stress distribution in the working area of the die 1 in the case of a large load.
