Description
Die Hauptpatentanmeldung betrifft eine Presse für keramische Vollkörper mit paarweise entgegengesetzt arbeitenden Preßstempeln in drei Raumkoordinaten allseits vor einem zentralen, den endgültigen Preßling aufnehmenden Raum, in -welchem sich der Druck aller Preß stempel ungehindert von Kernen oder Einbauten bis in das Zentrum des Preßlings auswirken kann, wobei sich an den zentralen Raum für jeden Stempel je eine seitlich geschlossene Vorkammer anschließt. Es wird dabei der Vorteil erzielt, daß die bei bekannten Preßlingen in der Regel vorhandene, verhältnismäßig weiche, weil vom Preßdruck nur wenig erfaßte Mittelschicht ganz vermieden oder jedenfalls auf ein unschädliches Maß zurückgeführt wird.The main patent application relates to a press for ceramic solid bodies with opposing pairs working press rams in three spatial coordinates on all sides in front of a central, the final pressed part receiving space, in which the pressure of all press rams is unhindered by cores or fixtures can affect up to the center of the compact, taking into account the central space for each punch each is connected to a laterally closed antechamber. It has the advantage that the known Pressings usually present, relatively soft, because they were only slightly covered by the pressing pressure Middle class is avoided entirely or at least reduced to a harmless level.
Nach der Hauptpatentanmeldung geschieht die Füllung der aus dem Zentralraum und den anschließenden Kammern bestehenden Form in der Weise, daß zunächst der die Form oben abschließende und mit einer als Vorkammer ausgebildeten Durchtrittsöffnung für den Oberstempel versehene Preßformdeckel abgenommen wird, so daß Zentralraum und Seitenkammern sowie die Unterkammer gefüllt werden können. Danach wird der Preß formdeckel wieder aufgesetzt und dann die Füllung der Form durch Füllen der obersten Kammer vollendet.After the main patent application, the filling of the central area and the subsequent ones is done Chambers existing form in such a way that first of all the form at the top and provided with a through-opening designed as an antechamber for the upper punch is removed so that the central space and side chambers as well as the lower chamber are filled can be. Then the press mold cover is put back on and then the filling of the mold completed by filling the top chamber.
Ist die Form auf diese Weise vollständig gefüllt, so wird zunächst der Oberstempel in die obere Vorkammer eingeführt, womit die Form vollständig geschlossen ist. Daraufhin beginnen die Kolbenpaare gleichzeitig mit der Preßwirkung auf das Preßmaterial. When the mold is completely filled in this way, the upper punch is first moved into the upper antechamber introduced, with which the mold is completely closed. Then the piston pairs begin simultaneously with the pressing action on the pressing material.
Um das nochmalige Füllen, also das Füllen der oberen Vorkammer zu ersparen, kann man nach der Erfindung nach Aufsetzen des Preßformdeckels das in die deckellose Form eingefüllte Material teilweise in die obere Vorkammer hineindrücken, was entweder durch die seitlichen Preßstempel oder vorzugsweise durch den Unterstempel geschehen kann. Da in der oberen Vorkammer ein leerer Raum vorhanden ist, wird bei diesem Überschieben kein nennenswerter Druck auf das Preßgut ausgeübt. Es wird lediglich die Füllung des ganzen Innenraumes der Form durchgeführt. Die Unterkammer kann entsprechend größer ausgebildet werden, so daß nach dem Überschieben der Preßmasse in der oberen Vorkammer alle Vorkammern gleich groß und mit etwa der gleichen Materialmenge angefüllt sind.In order to save the need to fill the upper antechamber again, according to the invention, after the mold cover has been put on, the material filled into the coverless mold can be partially pushed into the upper antechamber, which can be done either through the lateral ram or preferably through the lower ram . Since there is an empty space in the upper antechamber, no significant pressure is exerted on the pressed material when it is pushed over. Only the entire interior of the mold is filled. The lower chamber can be made correspondingly larger, so that after the molding compound has been pushed over in the upper antechamber, all antechambers are of the same size and filled with approximately the same amount of material.
Nachdem die Form auf diese Weise vollständig und gleichmäßig gefüllt ist, tritt der Oberstempel in die obere Vorkammer ein und schließt damit die Form, womit die eigentliche Pressung beginnt.After the mold is completely and evenly filled in this way, the upper punch enters the an upper antechamber and thus closes the mold, with which the actual pressing begins.
Bei dem neuen Verfahren ist es nicht mehr erforderlich, eine gesonderte Füllung der oberen Vorkammer vorzunehmen, vielmehr kann gleich nach VerfahrenWith the new method, it is no longer necessary to fill the upper antechamber separately rather, can be done immediately after the procedure

dem Aufsetzen des Formkastendeckels der Preßstempel in die obere Vorkammer eintreten. Die Bewegungen von Oberstempel, Unterstempel und Seitenstempel können durch bekannte Mittel aufeinander abgestimmt werden. Die Entlüftung erfolgt in üblicher Weise durch Spalte oder sonstige kleine Austrittsöffnungen. when the molding box cover is put on, the ram enters the upper antechamber. The movements upper punch, lower punch and side punch can be on each other by known means be matched. The ventilation takes place in the usual way through gaps or other small outlet openings.
Bei entsprechender Ausbildung der Preßform können Oberstempel und Unterstempel auch etwa gleichzeitig arbeiten, währenddem die Seitenstempel sich noch in Ruhe befinden. Der Oberstempel tritt dann in die obere Vorkammer ein, während der Unterstempel die Preßmasse in die obere Vorkammer hineindrückt. Beide Stempel werden zu diesem Zweck mit einem entsprechenden Voreilantrieb versehen.With an appropriate design of the mold, the upper punch and the lower punch can also be work at the same time while the side stamps are still at rest. The upper punch steps then into the upper antechamber, while the lower punch transfers the molding compound into the upper antechamber pushes in. For this purpose, both punches are provided with a corresponding advance drive.
