Description
Schleuderkopf für Sandschleuderformmaschinen mit auswechselbarem Futter Bei den bekannten- Formmaschinen mit einem Schleuderrad, welches in einem geschlossenen Gehäuse; ,dem Schleuderkopf, umläuft, wird die Geb,äusewandung durch die Schleifwirkung des Formsandes stark angegriffen. Man hat daher bereits .das Innere der Gehäuse mit Stahleinlagen ausgekleidet, die leicht ausgewechselt werden können. Der Verschleiß dieser Einlagen ist aber immer noch sehr groß, und es ist wünschenswert, sie durch .etwas Besseres zu ersetzen.Centrifugal head for sand centrifugal molding machines with exchangeable chuck In the known molding machines with a centrifugal wheel, which is in a closed Casing; , the centrifugal head, rotates, the Geb, äusewandung by the grinding effect of the molding sand strongly attacked. So you already have the inside of the housing lined with steel inserts that can be easily replaced. The wear But this deposit is still very large and it is desirable to get them through . to replace something better.
Versuche haben ergehen, daß Auskleidungen aus bestimmten Steinmassen eine viel höhere Widerstandsfähigkeit gegen den Angriff des Sandes haben als die besten -Sonderstähle. Diese Steinmassen lassen sich auch. als Formstücke herstellen, so daß ihre Anbxingung und gegebenenfalls ihre Auswechselung keine größeren Umstände und Zeitverluste mit sich bringt wie bei Stahleinlagen. Zur Erreichung des Erfindungszwecks eignen sich z. B. Einlagen aus Hartporzellan, Schmelzbasalt oder Silikastein.Attempts have been made that linings are made of certain stone masses have a much higher resistance to the attack of the sand than that best special steels. These stone masses can also. manufacture as fittings, so that their attachment and, if necessary, their replacement, are no major inconveniences and entails loss of time as with steel inserts. To achieve the purpose of the invention are suitable e.g. B. Inlays made of hard-paste porcelain, cast basalt or silica stone.
In .der Zeichnung ist eine Ausführungsform der Erfindung schematisch dargestellt, und zwar zeigt Abb. i einen Längsschnitt und Abb. 2 einen Querschnitt durch einen. Schleuderkopf mit der neuen Schutzeinlage..In .der drawing an embodiment of the invention is schematically shown, namely Fig. i shows a longitudinal section and Fig. 2 shows a cross section through a. Centrifugal head with the new protective insert ..
In .dem Kopf a ist in bekannter Weise das Schaufelrad b mit den -Schaufelne auf der Achse c angebracht. Die Steineinlagen schützen die Wandung des Kopfes u gegen den Angriff des Sandes.In .dem head a is the paddle wheel b with the -Schaufelne in a known manner mounted on axis c. The stone inlays protect the wall of the head u against the attack of the sand.
