Description

Form zum Pressen von Formsteinen aus plastischen massen, insbesondere Schamotte. Zusatz zum Patent 335802. Der Formrahmen zur Ausübung des Verfahrens nach dem Hauptpatent besteht aus einem geteilten gußeisernen Rahmen, an dessen Oberseite Einsätze mit vorstehenden Schneidkanten zum Abschneiden des überschüssigen Preßgutes angebracht sind. Diese Form kann nur in besonders dafür eingerichteten Fabriken hergestellt werden und weist auch im praktischen Gebrauch Mängel auf, die in der Regel in Schamottesteinfabriken mit ihren ungeübten Arbeitern nicht oder nur schwer behoben werden können.Mold for pressing molded bricks from plastic masses, in particular Chamotte. Addendum to patent 335802. The mold frame for carrying out the process according to the main patent consists of a split cast iron frame on the top Inserts with protruding cutting edges for cutting off the excess material to be pressed are appropriate. This form can only be used in specially equipped factories are produced and has deficiencies in practical use that are in the Usually not or only with difficulty in firebrick factories with their inexperienced workers can be fixed.

Um diese Nachteile zu beseitigen, wird gemäß der Erfindung nicht wie bei der Form nach dem Hauptpatent das Stahlband oben in den Rahmen eingesetzt, sondern es wird eine besondere ganze Innenwandung des Formrahmens aus Stahlblech hergestellt und so in dem Formrahmen angebracht, daß das Stahlblech auf beiden Seiten. des Formrahmens etwas vorsteht. Hierdurch ist man in der Lage, bei Abnutzung der oberen Kante durch Umdrehen der Form die Form mit ihrer anderen Kante weiter benutzen zu können. Außerdem bietet der untere vorstehende Rand: den Vorteil, .daß etwa auf der Bodenplatte zurückgebliebenes Preßgut durchschnitten wird', so daß stets, eine sichere und gute Auflage des Formrahmens gewährleistet wird. Um den Formling leicht aus dem Rahmen herauszubringen, werden die Innenwände der Form mit Fett oder öl bestrichen, so daß sich der Formling glatt ohne Schwierigkeit von den Formwänden löst, ohne daß der Stein irgendwelche Veränderung aufweist.In order to overcome these disadvantages, according to the invention is not how in the form according to the main patent, the steel band is inserted into the frame above, but a special whole inner wall of the mold frame is made from sheet steel and so mounted in the mold frame that the steel sheet on both sides. of the mold frame something protrudes. This will allow you to get through when the upper edge wears Turning the shape over to be able to continue using the shape with its other edge. aside from that the lower protruding edge offers: the advantage that something left behind on the base plate Preßgut is cut through ', so that always, a safe and good support of the mold frame is guaranteed. In order to easily get the molding out of the frame the inner walls of the mold were coated with fat or oil so that the molding was smooth detaches from the walls of the mold without difficulty, without any change in the stone having.

Auf der Zeichnung ist die Form gemäß der Erfindung in einem Ausführungsbeispiel dargestellt, und zwar zeigt: Fig. i einen senkrechten Schnitt und Fig. 2 eine Oberansicht des Formrahmens. Die Form besteht aus dem Holzrahmen io, der durch Schrauben 17 zusammengehalten wird und mit Griffen 18 zur bequemen Handhabung versehen ist. Die Innenwände des Formrahmens werden für sich :gesondert aus Stahlblechen 13 gebildet, welche über den Holzrahmen auf beiden Seiten etwa q. bis 5 mm überstehen. Durch die obere überstehende Kante wird das überschüssige Preßgut ebenso wie beim Gegenstande des Hauptpatents abgeschnitten.In the drawing, the form according to the invention is in one embodiment shown, namely: FIG. 1 shows a vertical section and FIG. 2 shows a top view of the mold frame. The shape consists of the wooden frame io, which is secured by screws 17 is held together and is provided with handles 18 for convenient handling. the Inner walls of the mold frame are separately: formed separately from sheet steel 13, which over the wooden frame on both sides about q. protrude up to 5 mm. By the upper protruding edge becomes the excess material to be pressed as well as with the object of the main patent cut off.

An Stelle der Einzelform kann in sonst bekannter Weise auch eine Doppelform zur Herstellung ,der doppelten Anzahl von Formlingen Verwendung finden, indem die Form durch eingesetzte, einfache oder doppelte Stahlblechwände in mehrere Kammern unterteilt wird. Ist die Stahlbandkante auf .der einen Seite abgenutzt, so kann durch' Umdrehen des Formrahmens dieselbe weiter benutzt, ihre Lebensdauer also verdoppelt wer den.Instead of the single shape, a double shape can also be used in an otherwise known manner for the production of twice the number of moldings are used by the Form through inserted, single or double sheet steel walls in several chambers is divided. If the steel band edge is worn on one side, then by turning the mold frame it continues to be used, their lifespan that is, it is doubled.
