Abstract

Die Erfindung betrifft eine kontinuierliche Ziehvorrichtung zum Geradeausziehen von Rohren oder Stangen mit zwei sich gegenüberliegenden, um angetriebene Kettenräder in einer gemeinsamen senkrechten Ebene endlos umlaufenden Treibkettenpaaren, an denen die das Werkstück am äußeren Umfang greifenden Ziehwerkzeuge angeordnet sind, die das Werkstück kontinuierlich durch einen der Ziehvorrichtung vorgeordneten Ziehring ziehen.The invention relates to a continuous pulling device for straight pulling of tubes or rods with two opposed to driven ones Sprockets endlessly revolving in a common vertical plane Drive chain pairs on which the workpiece grips the outer circumference Drawing tools are arranged that continuously through one of the workpiece Pull the pulling device upstream of the pulling ring.
Die Erfindung ist dadurch gekennzeichnet, daß jede Treibkette (2,3) mindestens einlaufseitig auf einer stetigen Umlenkbahn (7) geführt ist, deren Kurvenradius zur Reduzierung der Radialbeschleunigung der Kettenglieder im Aufsetzbereich (8) der an der Treibkette (2 oder 3) angeordneten Ziehwerkzeuge (6) auf das Werkstück größer als der halbe Abstand zwischen den beiden Treibketten (2,3) ist.
Figure 00000001
The invention is characterized in that each drive chain (2, 3) is guided, at least on the inlet side, on a continuous deflection path (7), the radius of the curve of which reduces the radial acceleration of the chain links in the mounting area (8) of the drawing tools arranged on the drive chain (2 or 3) (6) on the workpiece is greater than half the distance between the two drive chains (2,3).
