FIELD: process engineering.
SUBSTANCE: proposed roll mill comprises stand with working rolls, main drive, tube turning mechanism with two transmission shafts coupled with main drive via converter of uniform rotation into irregular rotation. One of said shafts is articulated with mandrel rod chuck while another one is coupled via gearing with biller chuck and tube turning front chuck. Stepless adjustment of precise alignment of grooves in chuck cams with those in pass is ensured by coupling transmission shaft with gearing drive gear by means of clamping and bearing conical couplings furnished with clamping and unclamping bolts while front chuck cam cross-section profile is provided with grooves mating with profile of finished ribbed tube.
EFFECT: accurate sizes, reduced wastes, expanded range of finished products.
