Dichte Gußstahlblöcke sind bereits in der Weise erzeugt worden, daß sie in ihrer Gußform seitlich zusammengepreßt wurden. Gegenüber diesem Zusammenpressen bietet die Art des Zusammenpressen nach der Erfindung den Vorzug, daß durch die Zusammensetzung und Pressung der Gußform wände verursacht wird, daß die Trichter und Blasen im Blocke von unten nach oben ausgedrückt werden. Das Verfahren wird in der Art ausgeführt, daß die an zwei zylindrischen Hälften durch Einsetzen zweier Keilstücke zu einem nach unten verjüngten Kegelstumpf zusammengesetzte Gußform nach erfolgtem Guß mit dem Gußblock dadurch zusammengepreßt wird, daß die beiden zylindrischen Hälften an den Keilstücken entlang nach unten und hierbei zu einem Zylinder zusammengezogen werden. Hierdurch tritt eine große Verbilligung in der Gesamt anlage ein.Dense cast steel blocks have already been produced in such a way that they are in their mold were pressed together laterally. Compared to this compression, the type of compression according to the invention offers the advantage that caused by the composition and compression of the mold walls becomes that the funnels and bubbles are expressed in the block from bottom to top. The method is carried out in such a way that the two cylindrical halves through Insertion of two wedge pieces to form a downwardly tapered truncated cone The casting mold is pressed together after the casting with the cast block in that the two cylindrical halves on the wedge pieces along downwards and hereby pulled together to form a cylinder. This results in a great reduction in the price Entire plant a.
Eine Vorrichtung zur Ausführung des Verfahrens ist in Fig. i, 2 und 3 in Ansichten von der Seite und im Grundriß dargestellt. Sie besteht aus drei Hauptteilen: der Gußform a, dem Umklammerungs- oder Führungsgerüst und dem Antrieb m, n. An apparatus for carrying out the method is shown in Fig. I, 2 and 3 in views from the side and in plan. It consists of three main parts: the mold a, the clasp or guide frame and the drive m, n.
Die zylindrische Gußform α ist in der Längsrichtung in zwei Hälften geteilt.The cylindrical mold α is divided into two halves in the longitudinal direction.
Das Gerüst besteht aus vier Stützen f, g, h, i, welche mit dem die Grundplatte darstellenden Druckring j> fest verbunden sind. In der Mitte und am Kopfende tragen die Stützen zwei Umklammerurigsringe d, e, welche gleichzeitig als Führung dienen. An den Umklammerungsringen d, e sind zwei senkrecht sich gegenüberliegende Keilstücke b, c mit dem spitzen Ende nach unten befestigt. Vor dem Gießen wird die in zwei Hälften geteilte, zylindrische Gußform α in das Umklammerungs- oder Führungsgerüst eingesetzt, so, daß die Keilstücke der Gußform die Gestalt eines abgestumpften Kegels geben. An der Gußform sind zwei Zahnstangen k, m so angebracht, daß sie mit den Keilstücken im rechten Winkel stehen. Die Zahnstangen greifen in das Zahnradgetriebe n, 0. The frame consists of four supports f, g, h, i, which are firmly connected to the pressure ring j> , which is the base plate. In the middle and at the head end, the supports carry two Umklammerurigsringe d, e, which also serve as guides. Two vertically opposite wedge pieces b, c are attached to the clasping rings d, e with the pointed end pointing downwards. Before casting, the cylindrical casting mold α , which is divided into two halves, is inserted into the clasping or guide frame so that the wedge pieces give the casting mold the shape of a truncated cone. Two racks k, m are attached to the mold so that they are at right angles to the wedge pieces. The racks mesh with the gear train n, 0.
Wenn das geschmolzene Metall in die Gußform gegossen ist, senkt sich die Gußform mit dem Metallblock unter Entlanggleiten an den Keilstücken b, c um ihre eigene Länge; dadurch wird der Durchmesser der Gußform bis zylindrischen Form verkleinert und daWhen the molten metal has been poured into the casting mold, the casting mold with the metal block descends by its own length while sliding along the wedge pieces b, c; thereby the diameter of the casting mold is reduced to a cylindrical shape and there
durch der Block in seiner Länge gleichmäßig zusammengedrückt.evenly compressed along its length by the block.
