Description

Die Erfindung betrifft eine Vorrichtung zur Herstellung von Formkörpern, insbesondere Kohleformkörpern, durch Rüttelverdichtung gemäß Oberbegriff des Patentanspruchs. Durch den stufenlos regelbaren Antrieb wird d;? Rüttelfrequenz dabei so eingestellt, daß sie einerseits den jeweiligen Körpergewichten und andererseits dem bei steigender Verdichtung veränderten Resonanzverhalten des Fc-mkörpers angepaßt wird. v'The invention relates to a device for the production of shaped bodies, in particular shaped carbon bodies, by vibratory compaction according to the preamble of the patent claim. The steplessly adjustable drive means that d ;? The vibration frequency is set in such a way that it is adapted on the one hand to the respective body weights and on the other hand to the resonance behavior of the Fc-m body which changes with increasing compression. v '

Die beschriebene Vorrichtung gemäß CH-PS 4 94 110 hat sich in der Praxis gut eingeführtThe described device according to CH-PS 4 94 110 has established itself well in practice

Der Erfindung liegt die Aufgabe zugrunde, eine weitere Verbesserung zu schaffen und damit eine höhere Qualität der verdichteten Formkörper zu erzielen. Erfindungsgemäß wird dies bei einer wie eingangs erläuterten Vorrichtung dadurch erreicht, daß der Formkasten auf einer schweren Grundplatte steht, die lose auf dem Rütteltisch angeordnet ist, und mit dieser verspannt istThe invention is based on the object of creating a further improvement and thus one to achieve higher quality of the compacted moldings. According to the invention, this is done with a like The device explained at the outset is achieved in that the molding box stands on a heavy base plate, which is loosely arranged on the vibrating table and is braced with it

Durch diese Maßnahme wird erreicht, daß die Grundplatte mit Formkasten und Füllung eine von der Deckplatte und vom Rütteltisch unabhängige Eigenschwingung ausführen kann. Dadurch werden nicht nur ungewöhnlich hohe Dichten, sondern auch eine überragend gute Homogenität der Formkörper erzieltBy this measure it is achieved that the base plate with molding box and filling one of the Cover plate and independent vibration from the vibrating table can perform. This will not just be unusually high densities, but also an outstandingly good homogeneity of the molded body is achieved

Die Vorrichtung wird anhand eines Ausführungsbeispiels näher beschrieben. In einem Gestell / ist ein Rütteltisch A, der den Formkasten X trägt, mitThe device is described in more detail using an exemplary embodiment. In a frame / is a vibrating table A, which carries the molding box X , with

ίο Unwuchtkörpern B versehen und auf Federn /gelagert Der Rütteltisch A ist über Zugstangen F mit dem Querhaupt G fest verbunden. Die Einheit aus Rütteltisch A mit Formkasten .X" und Querhaupt G ist im Gestell / über Rollen K geführt, die sich an den Zugstangen Fίο Equipped with unbalanced bodies B and mounted on springs / mounted. The vibrating table A is firmly connected to the crosshead G via tie rods F. The unit consisting of vibrating table A with molding box .X "and crosshead G is guided in the frame / over rollers K , which are attached to tie rods F.

υ abstützen. Im Formkasten ist eine Deckplatte E angeordnet, die über Führungsstangen //im Querhaupt G geführt wird. Mittels eines Zylinders Z, der am Querhaupt G befestigt ist, kann die Deckplatte E auf- und abgesenkt werden.support υ. A cover plate E is arranged in the molding box and is guided in the crosshead G via guide rods //. The cover plate E can be raised and lowered by means of a cylinder Z, which is attached to the crosshead G.

Auf dem Rütteltisch A befindet sich nun erfindungsgemäß eine Grundplatte D, auf der der Formkasten λ'mit seiner Bodenplatte C über Verschlußbolzen L fest verspannt ist
Im Betriebsfall schwingt die gesamte Einheit aus Rütteltisch A, Grundplatte D, Formkasten X, Bodenplatte Q Deckplatte E, Führungsstangen H, Zylinder Z Querhaupt G, Zugstangen F in dem Gestell /. Die Füllung des Formkastens X soll nun wie bekannt in einem zweistufigen Rüttelverfahren verdichtet werden.According to the invention, there is now a base plate D on the vibrating table A , on which the molding box λ 'is firmly clamped with its base plate C via locking bolts L.
In operation, the entire unit consisting of vibrating table A, base plate D, molding box X, base plate Q, cover plate E, guide rods H, cylinder Z, crosshead G, tie rods F swings in the frame /. As is known, the filling of the molding box X should now be compacted in a two-stage vibration process.

Dazu wird zunächst die Deckplatte £ abgesenkt, so daß sie lose auf der Füllung im Formkasten X aufliegt Werden nun die Unwuchtkörper B betätigt, so fängt der Rütteltisch A an zu vibrieren. Die mit dem Formkasten X über Verschlußbolzen L verbundene Grundplatte D wird von den Schwingungen des Rütteltisches A zu einer eigenen Schwingung angeregt Die auf der Füllung des Formkastens X aufliegende Deckplatte E wird wiederum von den Schwingungen des Formkastens zu einer eigenen Schwingung angeregt. Im Ergebnis wird die Füllung des Formkastens X durch die gegenläufigen Schläge der Deckplatte E und des Rütteltisches A verdichtetFor this purpose, the cover plate £ is first lowered so that it rests loosely on the filling in the molding box X. If the unbalanced bodies B are now actuated, the vibrating table A begins to vibrate. The base plate D connected to the mold box X via locking pin L is excited by the vibration of the vibrating table A to its own vibration which rests on the filling of the mold box X top plate E is in turn inspired by the vibrations of the flask to its own vibration. As a result, the filling of the molding box X is compacted by the counter-rotating blows of the cover plate E and the vibrating table A.

In der zweiten Stufe wird die Deckplatte E wie bekannt mittels Zylinder Z mit der Grundplatte D verspannt und der Rüttelvorgang fortgesetztIn the second stage, the cover plate E is clamped to the base plate D by means of cylinder Z, as is known, and the vibrating process is continued
