Abstract
Die Erfindung betrifft eine Vorrichtung zum Einfädeln von Rohren oder Stangen in ein Ziehaggregat mit umlaufenden Kettenpaaren, die das Werkstück mittels Klemmbacken am äußeren Umfang greifen und kontinuierlich durch einen dem Ziehaggregat zugeordneten, in einem Ziehringhalter angeordneten Ziehring ziehen, sowie mit einer aus der Ziehachse entfernbaren Greifvorrichtung zum Erfassen der am Rohr- oder Stangenanfang ausgebildeten Ziehangel und Führen des Rohranfanges in die Ziehvorrichtung. Dabei ist die Greifvorrichtung (5) als auf die Ziehangel (2) aufschiebbare Klemmhülse (6) ausgebildet, die in ihrem Inneren mehre an den Umfang der Ziehangel anlegbare, in Ziehrichtung selbstklemmende Spannelemente (7) aufnimmt und die in den zwischen zwei benachbarten Klemmbacken (10) jeder Kette (9) gebildeten Zwischenraum, die Klemmbacken (10) hintergreifend, einlegbar ist. The invention relates to a device for threading tubes or rods into a drawing unit with rotating pairs of chains, which grip the workpiece by means of clamping jaws on the outer circumference and continuously pull through a drawing ring assigned to the drawing unit and arranged in a drawing ring holder, and with a gripping device that can be removed from the drawing axis for grasping the drawbar formed at the start of the pipe or rod and guiding the start of the pipe into the pulling device. The gripping device (5) is designed as a clamping sleeve (6) which can be pushed onto the drawing bar (2) and which holds in its interior several clamping elements (7) which can be placed on the circumference of the drawing bar and which are self-clamping in the direction of drawing, and which in the between two adjacent clamping jaws ( 10) each chain (9) formed space, the clamping jaws (10) can be inserted behind.
