Description
Die Schaufeln von radial beaufschlagten Turbinen pflegt man im Gegensatz zur Herstellung der Beschaufelung bei axial beaufschlagten ,Turbinen nicht formschlüssig in vorgearbeitete Nuten des Schaufelträgers einzusetzen, sondern man walzt sie ein. Ebenso verbindet man vielfach die Kopfringe der Beschaufelung durch Einwalzen mit den Schaufeln. The blades of radially loaded turbines are maintained in contrast to production of the blades with axially loaded turbines not positively locked in Use pre-machined grooves of the blade carrier, but they are rolled in. as well the top rings of the blading are often connected to the blades by rolling.
ίο Den Gegenstand der Erfindung bildet eine Vorrichtung zum Einwalzen der Schaufeln von radial beaufschlagten Turbinen, und zwar besteht die Erfindung darin, daß jene Vorrichtung einen kegelförmigen Walzkörper enthält, dessen Achse einen Winkel mit der Achse seines Halters bildet. Man erhält auf diese Weise ein einfaches und leicht bedienbares Gerät.ίο The subject matter of the invention forms a Device for rolling in the blades of radially loaded turbines, namely the invention is that that device contains a conical roller body, whose axis forms an angle with the axis of its holder. One receives on this Way a simple and easy to use device.
Ein Ausführungsbeispiel der Erfindung ist in der Abbildung dargestellt.An embodiment of the invention is shown in the figure.
Die Vorrichtung ist in einer Lage dargestellt, bei der eine Schaufelreihe 1 in einen Schaufelträger 2 eingewalzt wird, und zwar dadurch, daß ein Lappen 3 in eine kleine Ringnut 4 eingepreßt wird. Hierzu dient eine Walze 5, die in Form eines Kegels ausgebildet ist, und zwar eines Kegels mit einer WaIzfiache 6, die den Baustoff 3 des Schaufelträgers in die Nut4 hineindrückt. Der Kegels ist drehbar auf einem Bolzen 8 gelagert, der vom Werkzeughalter 7 getragen wird. Die Achse des Werkzeughalters 7 fällt dabei annähernd mit der Richtung der Schaufel 1 zusammen und bildet mit der Achse des Kegels 5 einen Winkel α. Der Halter 7 wird in eine Werkzeugmaschine eingespannt, und es wird dann eine Bewegung zwischen Schaufelträger 2 und Walzgerät 5 hervorgerufen, sei es in der Weise, daß man die Beschaufelung stillstehen läßt und das Walzgerät bewegt 4„ oder daß man bei feststehendem Wakgerät die Beschaufelung umlaufen läßt.The device is shown in a position in which a row of blades 1 is rolled into a blade carrier 2 by a tab 3 being pressed into a small annular groove 4. A roller 5, which is designed in the form of a cone, specifically a cone with a roller area 6, which presses the building material 3 of the blade carrier into the groove 4, is used for this purpose. The cone is rotatably mounted on a bolt 8 which is carried by the tool holder 7. The axis of the tool holder 7 coincides approximately with the direction of the blade 1 and forms an angle α with the axis of the cone 5. The holder 7 is clamped in a machine tool, and a movement is then brought about between the blade carrier 2 and the rolling device 5, be it in such a way that the blading is left to stand still and the rolling device is moved 4 "or that the blading is rotated with the wak device stationary leaves.
