Abstract

Die Erfindung betrifft eine Vorrichtung zum Einfädeln von Rohren oder Stangen in ein Ziehaggregat mit umlaufenden Ketten, die das Werkstück am äußeren Umfang greifen und kontinuierlich durch einen dem Ziehaggregat zugeordneten, in einem Ziehringhalter angeordneten Ziehring ziehen, sowie mit einer aus der Ziehachse entfernbaren Zange zum Erfassen der am Rohr- oder Stangenanfang ausgebildeten Ziehangel und Führen des Rohranfanges in die Ziehvorrichtung.
Erfindungsgemäß wird vorgeschlagen, daß der Ziehringhalter (1) zusammen mit dem Ziehring (2) in und entgegen der Ziehrichtung um einen mindestens der Einspannlänge (L1) der umlaufenden Kette (6) des Ziehaggregates (5) entsprechenden Weg (L) verschiebbar geführt ist, daß die mechanisch schließende und öffnende Zange (10) in einem Zangenwagen (9) angeordnet ist, der parallel zur Ziehrichtung unabhängig vom Ziehringhalter (1) linear angetrieben zwischen Ziehring (2) und Ziehaggregat (5) verschiebbar ist und daß das Rohr (11) oder die Stange auf der dem Ziehring (2) und dem Ziehaggregat (5) abgewandten Seite zwischen Treibrollen (13) eingespannt ist.
