Abstract

1365438 Rolling tubes PERVOURALSKY NOVOTRUBNY ZAVOD and ELEKTROSTALSKY ZAVOD TYAZHOLOGO MASHINOSTROENIA 17 Nov 1972 53148/72 Heading B3M A tube skew-rolling mill employs a pair of disc rolls 12 (Fig. 3) which are mounted by shafts 11 in bushings 3, the axes of the shafts being eccentrically adjustable on either side of a workpiece tube 21 to vary the feed speed of the tube. Each roll is driven by a shaft 11 (Fig. 2, in plan) coupled through reduction gearing to a motor 24, and is supported by bearings 8, 9 and 10 in the bushing. Rotation of the bushing about its axis 7 by a drive 5 varies the position of the roll relative to the pass line 22. Similar adjustment of both rolls leads to a variation in the rolling speed due to the tube being contacted by different radial portions of the rolls. The axial position of each roll is adjustable by a nut 15 and sleeve 14, to vary the spacing between the rolls. The mill may be employed for piercing, expanding, sizing or straightening operations.
