Description

Preßstempel für keramische und andere plastische massen. Zusatz zum Patent 394481. Nach dein Hauptpatent bestehen die beim Pressen in der Preßrichtung gegeneinander verschiebbaren Teile des Preßstempels einerseits aus rostendem Metall, anderseits aus Messing oder ähnlichem Metall. In solchen Fällen, «-o es wegen der Härte des zu pressenden Gutes angebracht ist, beide Teile aus gehärtetem Stahl herzustellen, kann der dem Hauptpatent zugrunde liegende Zweck auch dadurch erreicht «-erden, (laß entweder zwei verschiedene Sorten Stahl für die gege-,ieinander verschiebbaren Stempelteile verwendet «-erden. «-elche dem Rosten verschieden stark widerstehen, oder daß der eine der beiden Teile an der gleitenden Fläche gut poliert, der andere Teil aber künstlich zum Rosten gebracht wird. Indem sich dann (las Preßgut an der rauben gerosteten Oberfläche festsetzt, bleibt durch das dauernde Reiben des Preßgutes beim Gebrauch des Stempels an dem anderen Teil dieser letztere in ähnlicher `eise blank wie bei dem Gegenstande des Hauptpatents der Teil aus dem nichtrostenden Material. Gemäß der Erfindung wird demnach der Gegenstand des Hauptpatentes im wesentlichen dadurch weiter ausgebildet, daß beide Stempelteile aus (lern gleichen Metall hergestellt sind, von denen aber der eine infolge anderen (etwa durch Zusätze bedingten) Verhaltens oder anderer Behandlung rostig ist, der andere dagegen blank bleibt.Press punches for ceramic and other plastic materials. Addition to Patent 394481. According to your main patent, they exist when pressing in the pressing direction mutually displaceable parts of the ram on the one hand made of rusting metal, on the other hand made of brass or similar metal. In such cases, «-o it because of the Hardness of the material to be pressed is appropriate, both parts are made of hardened steel, the purpose on which the main patent is based can also be achieved in this way (Either leave two different types of steel for the one that can be moved in relation to one another Stamp parts used «-erden. "-Which resist rusting to varying degrees, or that one of the two parts polished well on the sliding surface, the other Part of it is artificially rusted. By then (read Preßgut on the rob the rusted surface, remains due to the constant rubbing of the pressed material when using the stamp on the other part, the latter in a similar way blank as in the case of the subject of the main patent, the part made of the stainless material. According to the invention, therefore, the subject matter of the main patent essentially becomes further developed in that both stamp parts are made of the same metal of which one is due to other behavior (e.g. caused by additives) or other treatment is rusty, while the other remains bare.
