A control mechanism of daylight opening in two- and four-crank presses contains hydraulic safety devices of a slider against overloads, adjusting screws, and also worm-and-worm wheels, which transfer torques to the adjusting screws. Each suspension point of the slider is equipped with an individual driving from a hydraulic motor, which is connected to a hydraulic system for protection of the press slider against overloads. |
