[0002] Hydraulic devices are mainly used for press forming. Taking wheel hub processing as an example, the raw materials are placed on the lower die, and the upper die presses the raw materials downward to press the raw materials into the shape of the wheel hub according to the shapes of the upper and lower dies. Pressing the wheel hub requires strong pressure, which comes from the huge oil cylinder. During the rapid descent of the upper die, the oil cylinder needs to be filled with a large amount of hydraulic oil, and the descent speed depends on the speed of filling the hydraulic oil. During the return process, the return speed also depends on the speed of the hydraulic oil in the upper chamber of the oil cylinder being discharged back to the oil tank.
