FIELD: manufacturing process. ^ SUBSTANCE: invention relates to systems of crank presses, forming a line of pressing. Angle of rotation control unit of main shaft of crank gear of the press comprises a unit of output of the reference value of the angle of rotation and unit of measurement of the angle provided for each press, the unit issuing the command of speed and the actuation unit. Unit issuing the command displays the value of the command speed to the electric motor of the corresponding press taking into account the reference and the measured values of the angle of rotation of the main shaft. The actuation unit controls the speed of the electric motor of the respective press. The unit provides the unit of correction. The said unit adjusts the value of command speed or the reference value of the angle of rotation. Adjustment is made so that the difference between the reference value and the angle of rotation of the main shaft for each of the presses is within the predetermined range. ^ EFFECT: improved accuracy is provided by controlling the angle of rotation of the main shaft of the crank gear of the press and prevention of impact on one press of changes of press-load in the other press. ^ 7 cl, 7 dwg |
