ROLLING MILL Russian patent published in 1996 - IPC

FIELD: metal pressure forming. SUBSTANCE: rolling mill has a rolling stand and a drive mechanism. The rolling stand includes two pairs of mutually normal rolls. The rolling stand is mounted on the frame. Each roll has a drive line, consisting of a motor, a universal spindle, a crank shaft. The crank shafts are jointly connected by levers with the frame of the rolling mill. Torque of the electric motors, mounted on the frame of the rolling mill, is being transmitted through the universal spindles to the crank shafts and to rolling rolls. At that transmission the rolls are being synchronously rotated and the rolling stand performs reciprocation motion along the frame of the mill due to connection of the crank shafts with the frame of the rolling mill by levers. EFFECT: enhanced efficiency at making rolled strips with variable cross section along them. 1 cl, 2 dwg
