FIELD: metal forming.
SUBSTANCE: invention relates to metal forming, particularly, to cold rolling mills with moving reciprocating working stand. Cold rolling mill comprises working stand reciprocating along bed guides, rolls with calibres and gears driven double crank mechanism, vertically arranged in working mill, driven by two connecting rods to working stand. Double crank mechanism includes horizontally located crank and balancing shafts, on which there are gears, additional gears and counterweights for balance of inertia forces from working stand. Two gears are located on ends of additional shaft cantilever and are engaged with gears of crank shaft, and third gear is located in middle of additional shaft and is engaged with gear of drive shaft installed on bearings.
EFFECT: higher uniformity of loading of gearing of both halves of mechanism is ensured by the fact that between crank and drive shafts and parallel to them there is an additional shaft with three gears.
