Description

Gesenk zum Umschmieden von dickstegigen. Schienenprofilen in solche größerer Höhe Das Hauptpatent bezieht sich auf ,ein Gesenk zum Umschmieden von dickstegigen Schienenprofilen in solche größerer Höhe, insbesondere zur Herstellung des Anschlußstückes an Zungenschienen, Herzstückvollprofilspitzen usw. mit Preßbacken, die von beiden Seiten auf den Schienensteg einwirken. Das Gesenk zeichnet sich dadurch aus, daß die durch Schrägflächen an ihrem Rücken gegen das Preßstück bewegten Preßbacken mit einer ebenen Fläche ihres Kopfes an einer ebenen Fläche des Druckstempels anliegen, der gleichzeitig auf den Scheitel des Schienenkopfes drückt, wobei am Ende jeder Stufe des Preßvorganges die Preßbacken den Schienenfuß zwischen ihren unteren Flächen und einem Einsatzstück halten. Dieses Gesenk kann im wesentlichen nur bei solchen Profilen angewandt werden, bei denen eine gleichartige Werkstoffverteilung zur Mittel'-, achse vorhanden ist.Die for re-forging thick webs. Rail profiles in such greater height The main patent relates to, a die for re-forging thick webs Rail profiles at such a greater height, in particular for the production of the connection piece on tongue rails, frog full profile tips, etc. with press jaws that of both Act on the sides of the rail web. The die is characterized in that the pressing jaws moved against the pressing piece by inclined surfaces on their backs rest with a flat surface of their head on a flat surface of the pressure stamp, which simultaneously presses on the apex of the rail head, at the end of which each Stage of the pressing process the press jaws the rail foot between their lower surfaces and hold an insert. This die can essentially only be used with such Profiles are used in which a similar material distribution for the middle, axis is present.

Es gibt jedoch unsymmetrische Profile mit verschieden großer Werkstoffverteilung zur Mittelachse, z. B. das Vollzungenprofil Zu 2 bis 49. Das Umschmieden dieses Profis in ein anderes Profil bereitet infolge der Unsymmetrie Schwierigkeiten, die durch die vorliegende Erfindung beseitigt werden.However, there are asymmetrical profiles with differently large material distributions to the central axis, z. B. the full tongue profile on 2 to 49. The reforging of this professional in a different profile causes difficulties due to the asymmetry, which are eliminated by the present invention.

Dias Gesenk wird gemäß der Erfindung derart ausgebildet, daß diejenige Preßbacke, die einen größeren Weg zurückzulegen hat, mit größerer Geschwindigkeit bewegt wird. Dies kann z. B. dadurch erzielt werden, daß die Keilwinkel der die Preßbacken gegeneinander bewegenden Schrägflächen des Untergesenk es den verschiedenen Geschwindigkeiten entsprechend, mit denen die Preßbacken gegeneinander bewegt werden, verschieden sind.The die is formed according to the invention in such a way that that Press jaw, which has to cover a greater distance, at greater speed is moved. This can e.g. B. can be achieved in that the wedge angle of the Jaws against each other moving sloping surfaces of the lower die it the different Corresponding speeds at which the press jaws are moved against each other, are different.

In den Abb. i und 2 ist ein Ausführungsbeispiel der Erfindung dargestellt, und Abb. 3 zeigt eine umgeschmiedete Schiene im Querschnitt.In Figs. I and 2 an embodiment of the invention is shown, and Fig. 3 shows a forged rail in cross section.

Das Vollzungenprofil16 wird, wie dies in Abb.i dargestellt ist, zwischen die beiden Preßwerkzeuge 17, 18 gelegt. Die Preßwerkzeuge 17, 18 haben verschieden abgeschrägte Flächen 19, 2o, die den Abschxägungen in der Rinne 5 des Unterteiles 6 entsprechen. Die Vorsprünge 21, 22 sind verschieden entsprechend dem Erfordernis, das Werkstück in die notwendige Form zu pressen. In der Rinne 5 wird zur Begrenzung der Höhe eine Einlage 23 vorgesehen.The full tongue profile16 is, as shown in Fig.i, between the two pressing tools 17, 18 placed. The pressing tools 17, 18 have different beveled surfaces 19, 2o, the cut-offs in the channel 5 of the lower part 6 correspond. The projections 21, 22 are different according to the requirement to press the workpiece into the necessary shape. In the channel 5 is used to limit the height of an insert 23 is provided.

Wie beim Hauptpatent wird durch den Stempel 9 einer Schmiedemaschine o. dgl. der Druck oder Schlag auf die beiden Preßwerkzeuge 17, 18 und damit auf die Schiene 16 übertragen. Infolge der verschiedenen Schräge der Preßbackenführungen im Unterteil 6 werden die beiden Preßbacken mit verschiedener Geschwindigkeit gegeneinander bewegt und infolgedessen auch der Werkstoff in der einen Richtung mehr verdrängt als in der anderen. Es ergibt sich nach Beendigung der in Abb. i dargestellten Stufe des Umschmiedevorganges eine Form der Schiene, die in Abb. 2 zu sehen ist. Mit Hilfe neuer Preßbacken 24, 25 und einer neuen Einlage 26 wird dann die in Abb.,-> dargestellte Schiene 27 auf demselben Wege wie vorher in die endgültige Form nach Abb.3 übergeführt.As with the main patent, the punch 9 of a forging machine o. The like. The pressure or impact on the two pressing tools 17, 18 and thus on the rail 16 transferred. As a result of the different slopes of the press jaw guides In the lower part 6, the two press jaws are against each other at different speeds moves and, as a result, the material is displaced more in one direction than in the other. It results after the completion of the stage shown in Fig. I the reforging process has a form of rail that can be seen in Fig. 2. With help new jaws 24, 25 and a new insert 26 is then shown in Fig., -> Rail 27 converted into the final shape according to Fig. 3 in the same way as before.
