Description

Herstellung von Formen zur Verschweißung von Schienenkreuzungen Die Herstellung von Formen für die aluminothermische Verschweißung von Schienenkreuzungen macht insofern Schwierigkeiten, als man gezwungen ist, für die verschiedenartigen Querscbnittsformen der Schienen und die verschiedenen Winkel, unter denen die Schienen sich kreuzen, viele kostspielige Modelle herzustellen.Manufacture of molds for welding rail crossings Die Manufacture of molds for the aluminothermic welding of rail crossings makes difficulties insofar as one is forced to look for the diverse Cross-sectional shapes of the rails and the various angles at which the rails are made cross each other to manufacture many expensive models.

Diesen Übelstand beseitigt die Erfindung. Diese besteht darin, daß zwei scharnierartig bewegliche Platten vorgesehen sind, die in den der zu schweißenden Kreuzung entsprechenden Winkeln zueinander einstellbar und auf welchen die entsprechenden Modellteile für die Schienen und den zu gießenden Eisenwulst auswechselbar angeordnet sind.The invention eliminates this drawback. This consists in that two hinge-like movable plates are provided, which are in the to be welded Crossing corresponding angles to each other adjustable and on which the corresponding Model parts for the rails and the iron bead to be cast are arranged to be exchangeable are.

Die Zeichnung stellt eine Ausführungsform der Erfindung dar, und zwar zeigt Abb. i seine Vordexansicht mit aufg.estampftem Formkasten, Abb. z einen Schnitt nach der Linie A-B der Abb. i, Abb.3 eine Seitenansicht.The drawing illustrates an embodiment of the invention, namely Fig. i shows his Vordex view with a stamped molding box, Fig. z shows a section according to the line A-B of Fig. i, Fig.3 is a side view.

In Abb. q. und 5 ist dargestellt, wie die mittels der in Abb. i bis 3 dargestellten Vorrichtung hergestellten Formteile zum Verschweißen einer Kreuzung am Werkstück zusammengestellt sind, und zwar zeigt Abb.5 eine zum Verschweißen zusammengestellte Kreuzung, Abb. .f einen Schnitt nach der Linie xx der Abb. 5.In Fig.q. and Fig. 5 is shown how the by means of the in Fig. i to 3 device shown produced molded parts for welding an intersection are assembled on the workpiece, namely Figure 5 shows one assembled for welding Crossing, Fig. .F a section along the line xx in Fig. 5.

Auf zwei scharm#erartig um den Punkt c drehbar angeordnetem Platten a und b sind die Schienenmodellhälfttene und f mittels Schrauben g befestigt. Die Platten a und b lassen sich m einem gewünschten Winkel mittels der Schraube k zwischen den Platten m und 3a feststellen. Der zur Herstellung des Wulstes erforderliche auswechselbare Modellteil i wird durch die Schraube h zwischen den Schenkeln der Winkel, die von e und f gebildet werden, in seiner Lage gehalten. Der Modellteil l für den Einlauftrichter ist in geeigneter Weise zwischen den Plattem und b angeordnet.The rail model halves and f are fastened by means of screws g on two plates a and b, which are rotatably arranged around point c. The plates a and b can be fixed at a desired angle by means of the screw k between the plates m and 3a. The interchangeable model part i required to produce the bead is held in its position by the screw h between the legs of the angles formed by e and f. The model part l for the inlet funnel is arranged in a suitable manner between the plates and b.

Der Vorgang beim Formen ist folgender: Die Vorrichtung wird, nachdem die entsprechenden Schienenmodelle e und f sowie die Modellteile für den Wulst! und den Einlauf l auf den Platten a und b befestigt und letztere in d°n Winkeln a, 3 der herzustellenden Schienenkreuzung eingestellt sind, so auf die Werkbank p gelegt, daß die Öffnung des Winkels nach oben gerichtet ist. Hierauf wird ein .entsprechend gestalteter Formkastell o zwischen die Schenkel dies Winkels bestellt (Abt. z) und in an sich bekannter Weise mit Sand aufgestampft.The process of molding is as follows: After the corresponding rail models e and f and the model parts for the bead! and the inlet l is attached to the plates a and b and the latter are set at d ° n angles a, 3 of the rail crossing to be produced, placed on the workbench p so that the opening of the angle is directed upwards. A correspondingly designed molded fort o is then ordered between the legs of this angle (section z) and pounded with sand in a manner known per se.

Die auf diese Weise hergestellten Formteile g, r, s und t werden, wie Abb. 5 zeigt, in die entsprecenden Winkel a, ß der zu schweißenden Kreuzung so eingelegt, daß sie oberhalb der Schienenköpfe sektorartig zusammenschließen. Die unterhalb der Schienenfüße liegende Forma wird in beliebiger Weise hergestellt. The molded parts g, r, s and t produced in this way, as shown in Fig. 5, are inserted into the corresponding angles α, β of the intersection to be welded in such a way that they join together in a sector-like manner above the rail heads. The shape below the rail feet can be produced in any way.
