FIELD: plastic metal working, namely mills for cold rolling of tubes. SUBSTANCE: mill for cold rolling of tubes includes stationary powered housing; movable cartridge supporting in its body rolling rolls and backup rolls mounted in bearing assemblies; double-flow drive unit for reciprocation motion of cartridge. Double-flow drive unit is in the form of planetary-crank mechanism providing rectilinear horizontal motion of cranks joined with body of cartridge. Body of movable cartridge includes two separate vertical struts joined with cranks of drive unit. Each strut is made with possibility of fixing it in direction normal relative to axis of rolling process in bearing assemblies of cranks of drive unit and of backup rolls. EFFECT: lowered mass of cartridge, shortened spacing between struts of stationary housing, increased rigidity and strength of stationary housing. 2 dwg
