Description

EMI1.1
Die Erfindung betrifft eine Profilstange zur Herstellung von Schaufeln für Gas-, Dampfturbinen' Pumpen od. dgl. und besteht darin, dass die Profilstange eine im Querschnitt dem gewünschten Schaufelquerschnitt entsprechende Form hat, die in der Schaufelmitte eine dem Sehaufelkopf bzw. Schaufelfuss entsprechende Verstärkung in der Weise aufweist, dass diese Verstärkung den Schaufelquerschnitt beiderseitig in ungefähr gleicher Grösse überragt, so dass durch Abarbeitung der für die Schaufeln vorgesehenen Profilteile der Schaufelkopf bzw. der Schaufelfuss hergestellt werden kann.
In der Zeichnung ist die Erfindung veranschaulicht, u. zw. zeigt Fig. 1 einen profilierten Stab in schaubildlicher Darstellung und Fig. 2 in derselben Darstellungsweise eine fertiggestellte Schaufel.
Aus den profilierten Stangen 1, welche beispielsweise aus nicht rostendem Stahl gezogen werden können, werden die Schaufeln herausgearbeitet. Dies erfolgt, wie ohne weiteres ersichtlich, dadurch, dass zur Herstellung der Schaufeln 2 die Verstärkung 2 entfernt wird, während zur Herstellung der Schaufelköpfe die Profilteile 1, und 1" abgearbeitet werden. Durch diese Arbeitsvorgänge sowie durch ein allfälliges Nachdrehen der zylindrischen Fortsätze erhält man allseitig bearbeitete Schaufeln.
Das Profil der Stange 1, aus welchem die Schaufeln herausgearbeitet werden, wird selbstverständlich der jeweilig gewünschten Schaufelform bzw. der gewünschten Form von Schaufelfuss und Schaufelkopf angepasst. Es kann aber auch bei vorliegender Profilform der Schaufelkopf beispielsweise mit quadratischem Querschnitt ausgebildet werden.
**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

EMI1.1
The invention relates to a profile rod for the production of blades for gas, steam turbines' pumps or the like and consists in that the profile rod has a shape corresponding in cross section to the desired blade cross section, which in the blade center has a reinforcement corresponding to the blade head or blade root the way that this reinforcement projects beyond the blade cross-section on both sides in approximately the same size, so that the blade head or the blade root can be produced by processing the profile parts provided for the blades.
In the drawing the invention is illustrated, u. Between FIG. 1 shows a profiled rod in a perspective view and FIG. 2 shows a finished blade in the same way of illustration.
The blades are machined from the profiled rods 1, which can be drawn from stainless steel, for example. This is done, as is readily apparent, by removing the reinforcement 2 to produce the blades 2, while the profile parts 1 and 1 ″ are machined to produce the blade heads. These operations and any subsequent turning of the cylindrical extensions are obtained blades machined on all sides.
The profile of the rod 1, from which the blades are machined, is of course adapted to the respective desired blade shape or the desired shape of blade root and blade head. However, the blade head can also be designed with a square cross-section, for example, with the profile shape present.
