DEVICE FOR DRAWING LONG CUT ARTICLES Russian patent published in 1997 - IPC

FIELD: metallurgy and metal working. SUBSTANCE: in device for drawing long cut articles of known design roller chains on which clamping chucks are secured should be pulled manually. If such pulling is done untimely, roller chains and chain sprockets will suffer from permature wear. Drawing device of new design version is provided with tension members creating, in direction opposite to driving chain sprockets, the tension forces on tension chain sprockets displaced with their bearing housings in longitudinal direction of roller chains. Self-braking wedge precludes reciprocating oscillations of tension chain sprockets. Automatic adjustment of roller chain tension decreases wear of drawing device and eliminates flu changes in speed at transportation of longitudinal drawn articles. Device is good for transportation of cables or pipes. EFFECT: reduced wear of device. 7 cl, 3 dwg
