Description

Verfahren zur Herstellung von Gewinderohrstutzen mit Innengewinde für den Anschluß der Ablaßhähne an Waschkesseln u. dgl. Für den Anschluß der Ablaßhähne an Waschkesseln und in ähnlichen Fällen ist es vielfach baulich bedingt oder vorteilhaft, längere Rohrstutzen. zwischenzuschalten, um den Ablaßhabn bequem bedienbar anordnen und den Wasserablauf an eine gewünschte Ste:'le dirigieren zu können.Process for the production of threaded pipe stubs with internal thread for connecting the drain cocks to washing kettles etc. For connecting the drain cocks on washing kettles and in similar cases, it is often structural or advantageous to longer pipe sockets. interposed to conveniently arrange the Ablaßhabn to operate and to be able to direct the water drain to a desired location.

Diese Rohrstutzen besitzen in der Regel auf ihrem innern Ende Außengewinde und an ihrem anderen Ende für das Anschrauben des AblaBh;ahus Innengewinde.These pipe sockets usually have external threads on their inner end and at its other end for screwing on the AblaBh; ahus internal thread.

Bisher wurden derartige Rohrstutzen aus Temperguß hergestellt, womit ihnen die jedem Gußerzeugniseigenen nachteiigen Eigenschaften, unter anderem geringe Stoßfestigkeit, rauhe Außen- und Innenfläche, damit in Verbindung stehende höhere Neigung zu Rostansatz usw.- anhaften. Außerdem steat sich die Gwßherstellung verhältnismäßig kostspie:i@g, zumal man auf Temperguß angewiesen ist.So far, such pipe sockets were made of malleable cast iron, with which to them the disadvantageous properties inherent in every cast product, including minor ones Impact resistance, rough outer and inner surface, related higher Tendency to form rust, etc. In addition, the production of Gwß is relatively slow kostspie: i @ g, especially since you have to rely on malleable cast iron.

Die Erfindung bezweckt, die Herste'.lung solcher Gewinderohrstutzen zu vereinfachen und dadurch wirtschaftlicher zu gestalten.The aim of the invention is to manufacture such threaded pipe stubs to simplify and thus to make it more economical.

Sie besteht darin, daß hierfür Rohre oder Abfallrohrstücke verwandt werden, die auf bestimmte Länge geschnitten und deren für Innengewinde vorgesehenen Enden durch Stauchen oder sonstwi:e aufgeweitet werden.It consists in the use of pipes or pieces of waste pipe for this purpose which are cut to a certain length and which are intended for internal threads Ends are widened by upsetting or otherwise.

Die Formgebung der Rohrstutzen kann auf diese Weise, nachdem sie auf Länge geschnitten sind, in einem Arbeitsgang erfolgen, der maschinell äußerst einfach durchzuführen ist.The shape of the pipe socket can be done in this way after it is on Length are cut in take place in an operation that is mechanically is extremely easy to perform.

Es ist einleuchtend, zumal wenn Ahfallrohrstücke verwendet werden, daß die Herstellung der Gewinderohrstüc'ke wesentlich wirtschaftlicher als in Tempergußerfolgen kann und sie zudem den Gußerzeugnvssen weit überlegen sind.It makes sense, especially when pieces of downpipe are used that the production of the threaded pipe pieces is much more economical than in malleable cast iron and they are also far superior to cast products.

Als weitere Vorzüge des neuen Herstellungsverfahrens wären zu erwähnen, da.ß jeglicher Ausschuß im Herstellungsverfahren fortfällt, der in. jedem Gießprozeß unvermeüdlich ist, womit der Grad der Wirtschaftlichkeit weiter erhöht wird.Other advantages of the new manufacturing process that should be mentioned are that there is no scrap in the manufacturing process that occurs in every casting process is indefatigable, which further increases the level of economic efficiency.
