Description
Gießform für aluminothermische Schweißungen. Für aluminothennische Schweißungen werden Formen benutzt, die so hergestellt werden, daß man einen Formkasten über einem Modell mit Sand ausstampft, oder man benutzt Formen, die als Kokille ausgebildet sind und ganz aus Metall bestehen und, wenn nötig, mit feuerfester Masse ausgestrichen werden. Die aus Sand hergestellten Formen können nur einmal benutzt werden und müssen mit ziemlichem Aufwand an Arbeit jedesmal neu angefertigt werden. Dauerformen aus Metall verzehren einen erheblichen Teil diQr zur Schweißung der Werkstücke aufgewendeten Wärme, besonders an solchen Stellen, wo die Oberfläche und die Masse der Form im Vergleich mit dem zu schweißenden Stück groß ist.Casting mold for aluminothermic welds. For aluminothennial niches Welds are used shapes that are made in such a way that you can make a molding box stamping out with sand over a model, or using molds as a chill mold are designed and made entirely of metal and, if necessary, with refractory mass be crossed out. The molds made from sand can only be used once and have to be remade each time with a considerable amount of work. Permanent forms made of metal consume a considerable part of the diQr for welding the Workpieces expended heat, especially in those places where the surface and the mass of the mold is large compared with the piece to be welded.
Gegenstand der vorliegenden Erfindung ist eine Form, die zum Teil als Kokille und zum Teil: als Formkasten ausgebildet ist und es ermöglicht, solche Stellen, an welchen die Wirkung der Kokille unvorteilhaft ist, aus Smid o. dgl. abzuformen.The present invention is a form that in part as a mold and in part: is designed as a molding box and allows such Places where the effect of the mold is unfavorable, made of Smid or the like. to mold.
In der Zeichnung, welche eine Ausführungsform darstellt, zeigt Abb. z den Querschnitt einer solchen Form, Abb.2 die Draufsicht. Abb.3 zeigt den Gebrauch der Gießform bei der Schweißung. a ist eine Metallform, b eine kastenförmige Aussparung dieser Form, die über einem Modell c mit Sand ausgestampft wird oder in die Sandkerne eingesetzt werden. Der Zwischenraum zwischen Modell c und Sandausstampfung wird durch einen Modellteil e gewahrt.In the drawing, which shows an embodiment, Fig. Z shows the cross-section of such a shape, Fig.2 shows the plan view. Figure 3 shows the use of the mold for welding. a is a metal form, b a box-shaped recess of this form, which is stamped with sand over a model c or into which sand cores are inserted. The space between model c and the ramming out of sand is preserved by a model part e.
