Das Verfahren hat den Zweck, RadreifenThe purpose of the procedure is to produce wheel tires
herzustellen, welche ungefähr bis zur Mitte ihres Querschnittes außen hart, innen weich und zähe sind, um dadurch die Radreifenbrüche im Eisenbahnbetriebe zu verhindern.to produce which are hard on the outside and soft on the inside to approximately the middle of their cross-section and are tough in order to prevent tire breakage in railway operations.
Das Verfahren besteht darin, daß in einen aus härtbarem und schweißbarem Stahl hergestellten Ring α (Fig. ι) ein aus zähem Schweißeisen hergestellter Ring b in folgender Weise eingeschweißt wird.The method consists in that a ring b made of tough welding iron is welded into a ring α made of hardenable and weldable steel (FIG. 1) in the following manner.
Beide Ringe werden in der Schweißhitze in das Untergesenk c (Fig. 2) einer hydraulischen Presse oder eines Dampfhammers eingelegt. Hierauf wird ein Lochdorn d, dessen Durchmesser bedeutend größer ist als der Lochdurchmesser der Scheibe b, durch letztere hindurchgepreßt. Eventuell kann das Lochen der Scheibe b erst in der Schweißhitze vorgenommen werden. Infolge des Durchpressens des Lochdornes wird die Scheibe b auseinandergetrieben und dadurch das zur Schweißung erforderliche Zusammenpressen der Schweißflächen der beiden Ringe α und b bewirkt.Both rings are placed in the lower die c (Fig. 2) of a hydraulic press or a steam hammer in the heat of welding. Then a piercer d, the diameter of which is significantly larger than the hole diameter of the disk b, is pressed through the latter. Perhaps the perforation of the disc b can only be carried out in the welding heat. As a result of the piercing pin being pressed through, the disk b is driven apart, thereby causing the welding surfaces of the two rings α and b to be pressed together, which is necessary for welding.
Der aus den beiden Ringen α und b zusammengeschweißte Ring (Fig. 3) wird in bekannter Weise mittels des Hornhammers weiter ausgestreckt und hierauf in einem Bandagfenwalzwerk zumThe ring welded together from the two rings α and b (Fig. 3) is extended in a known manner by means of the horn hammer and then in a bandage rolling mill to

Der in den äußeren Ring einzuschweißende innere Ring kann event, auch die aus Fig. 5 ersichtliche Form erhalten. Der fertige Radreifen hat dann im Querschnitt ein Aussehen nach Fig. 6.The inner ring to be welded into the outer ring can possibly also be the one from FIG. 5 Obtain apparent form. The finished wheel tire then has an appearance in cross section according to Fig. 6.
