METHOD OF CONTROLLING FEEDING DRIVE OF GEAR-ROLLING MILL Russian patent published in 1996 - IPC

FIELD: mechanical engineering. SUBSTANCE: method comprises shaping a signal to control of position and speed of the support and signal of compensation of pulsation of rolling force and deformation of members of the force chain under the action of this force and transmitting these signals to the actuating hydraulic cylinder through servo valves. The signal to control of position and speed of the support is fed through a servo valve that possesses less transmitting capability. The signal of compensation of the force pulsation of rolling and deformation of force chain members under the action of this force is fed through a servo valve of greater transmitting capability. EFFECT: improved accuracy of rolling. 1 dwg
