Description

Verfahren zur Herstellung von Metallflügeln mit vollem, aber veränderlichem Querschnitt für Triebkörper Die Erfindung betrifft ein Verfahren zur Herstellung von Metallflügeln mit vollem, aber veränderlichem Querschnitt, beispielsweise für Schrauben oder Schraubenpropeller oder sonstige Triebkörper.Method of making metal wings with full but changeable Cross-section for drive units The invention relates to a method of production of metal wings with full, but variable cross-section, for example for Screws or screw propellers or other propulsion units.

Die Erfindung besteht darin, daß der Metallflügel durch ein Walzenpaar mit symmetrischem Kaliber ausgewalzt wird und das endgültige Profil aus dem so erhaltenen symmetrischen Profil durch Entfernen des überflüssigen Werkstoffes hergestellt wird.The invention consists in that the metal wing by a pair of rollers is rolled out with symmetrical caliber and the final profile from the so obtained symmetrical profile is produced by removing the superfluous material.

Es werden dadurch die Vorteile des Walzverfahrens gegenüber dem sonst üblichen Schmiede- und Bearbeitungsverfahren beibehalten, weil die nachträgliche Bearbeitung nur an der einen Kante, vorzugsweise der Vorderkante des Flügels, erfolgt, während dieser seine grundlegende Form durch das einfache Walzverfahren erhält.Thereby the advantages of the rolling process compared to the usual usual forging and machining processes are retained because the subsequent Machining only takes place on one edge, preferably the leading edge of the sash, while this gets its basic shape through the simple rolling process.

Die Herstellung dieser Metallflügel wird dadurch vereinfacht und verbilligt. Abb. i stellt schematisch die Walzen zur Herstellung des symmetrisch ergänzten Flügelschnittes dar, während Abb. z in vollen Linien den symmetrischen Flügelschnitt und in gestrichelten Linien die Begrenzungslinie des nach einseitigem Abschneiden verbleibenden Flügelschnittes zeigt.The production of these metal wings is simplified and made cheaper. Fig. I shows schematically the rollers for producing the symmetrically supplemented wing cut while Fig. z shows the symmetrical wing section in full lines and broken lines Lines the boundary line of the wing cut remaining after one-sided cutting shows.
