 Dorn der Fall ist. Es ist natürlich nicht notwendig, dass die Bewegungen der Spindel d und dos Dornes i durch Verbindung derselben mit den Walzen hervorgerufen werden, es können auch besondere Antriebsvorrichtungen für die Teile benutzt werden, die dann so einzurichten sind, dass die Teile d und i die vorgeschriebenen Bewegungen ausführen. Der Dorn kann auch stillstehen, wenn derselbe nur in das Fertigkaliber der Walzen hinein-

 kennen, die aus einem Zahnrad und einem   Federgehäuse   bestehen. Werden die Walzen a durch irgendeine beliebige Vorrichtung in pendelnde Bewegungen versetzt, so ziehen sie in der bekannten Weise das Material b in sich hinein und strecken dasselbe absatzweise aus.

   Da nun der Dorn f das Ausstrecken des Materiales im Innern dos Blockes verhindert, so wird das Material in den   äusseren Schichten über den Dorn ausgestreckt worden,   so dass ein nahtloses Rohr entsteht. 



   PATENT-ANSPRÜCHE : 
1. Verfahren zur Herstellung nahtloser Rohre aus massiven Blöcken, dadurch gekennzeichnet, dass der Block gegen einen Lochdorn gedrückt unter gleichzeitiger Einwirkung von Kaliberwalzen in seiner   Längsrichtung   absatzweise tiber dem Lochdorn zum Rohr umgeformt wird.

 EMI2.1
 Dorn is the case. It is of course not necessary that the movements of the spindle d and dos mandrel i be brought about by connecting them to the rollers; special drive devices can also be used for the parts, which must then be set up so that parts d and i are prescribed Perform movements. The mandrel can also stand still if it only goes into the finished caliber of the rolls.

 know, which consist of a gear and a spring housing. If the rollers a are set in oscillating movements by any device, they pull the material b into them in the known manner and stretch the same out intermittently.

   Since the mandrel f prevents the material from stretching inside the block, the material in the outer layers is stretched out over the mandrel so that a seamless tube is created.



   PATENT CLAIMS:
1. A method for the production of seamless tubes from solid blocks, characterized in that the block is pressed against a piercer with the simultaneous action of caliber rollers in its longitudinal direction stepwise over the piercer to form the tube.

2. Ausführungsform des Verfahrens nach Anspruch 1, dadurch gekennzeichnet, dass der Lochdorn eine den Pendelschwingungen der Walzen entsprechende Hin- und llpr- bewegung erhält. EMI2.3 2. Embodiment of the method according to claim 1, characterized in that the piercer receives a reciprocating motion corresponding to the pendulum oscillations of the rollers. EMI2.3
