In this embodiment, the intelligent control hydraulic system has 4 working oil ports: an oil inlet P is communicated with a check valve 1, and is communicated with an oil inlet P of a proportional overflow valve 3, a high-frequency-response closed-loop proportional direction valve 4, a pressure regulating valve 2 and a two-position four-way electromagnetic valve 5 after passing through the check valve 1, an oil return port T is communicated with the proportional overflow valve 3, the high-frequency-response closed-loop proportional direction valve 4, the pressure regulating valve 2, the two-position four-way electromagnetic valve 5, an oil return port T of an electromagnetic ball valve 7 and an A port of a hydraulic control check valve 8, an oil cylinder plug cavity is communicated with a B port of the hydraulic control check valve 8, a pressure sensor 9 and a P port of the electromagnetic ball valve 7, and an oil cylinder rod cavity is communicated with a working oil port of a sequence valve 6.
In this embodiment, the intelligent control hydraulic system pressure design is adjustable oil piping system, and the required different pressures are realized to the accessible is adjusted to can be through the audio-visual demonstration pressure size of manometer, realize accurate pressure control through proportional overflow valve 3, realize the excessive pressure overflow safety protection function through pressure-regulating valve 2.
In the embodiment, the small-sized high-precision intelligent control hydraulic system controlled by the elements such as the proportional overflow valve 3, the high-frequency-response closed-loop proportional directional valve 4 and the like can realize the reliable operation of three working procedures of descending, pressing and returning of the press oil cylinder 13.
The working principle of each process of the intelligent control hydraulic system of the embodiment is as follows:
the press oil cylinder 13 goes down, the electromagnets YA1 and YAB1 are electrified, and the pressure of the system is regulated by the pressure regulating valve 2. The electromagnets YA1 and YAB1 are electrified to enable the inlet oil to reach the oil cylinder plug cavity through the high-frequency-response closed-loop proportional directional valve 4 and the electromagnetic ball valve 7, and meanwhile, the oil in the oil cylinder rod cavity returns to the oil tank through the sequence valve 6 and the high-frequency-response closed-loop proportional directional valve 4, so that the oil cylinder rod falls, and the falling process of the press is realized. The sequence valve 6 has a support function so that the oil cylinder rod does not fall down in the oil cylinder 13 when not working. The oil cylinder 13 is provided with a travel limit switch, plays roles of safety protection and electric signal switching, and carries out the next pressing working procedure after the cylinder rod falls in place and sends a signal.
The pressing working procedure is that when the cylinder rod falls in place, the stroke limit switch sends a signal, the high-frequency-response closed-loop proportional direction valve 4 receives a control signal sent by the electric control part of the proportional direction valve and formulated in advance according to the processing requirement, so that the oil passing amount of the proportional direction valve can be accurately controlled through the valve, the working pressing amount of the cylinder rod, namely the pressing speed, is accurately controlled, meanwhile, the proportional overflow valve 3 also receives a control signal sent by the electric control part of the proportional overflow valve and formulated in advance according to the processing requirement, so that the system pressure oil liquid pressure can be accurately controlled, and the pressure when the cylinder rod works and presses down is accurately controlled. Because the proportional overflow valve 3 and the proportional directional valve can form a closed-loop control loop with the pressure gauge, the pressure sensor 9, the travel limit switch and other electrical elements through the electrical control part of the proportional overflow valve and the proportional directional valve, the whole hydraulic system is simple and convenient to operate, efficient, intelligent and accurate in processing.
And in the return process, after the pressing working process is finished, the electromagnets YA1 and YAB1 are powered off, the electromagnets YAC1 and YA5 are powered on, at the moment, the oil enters the oil cylinder rod cavity through the high-frequency-response closed-loop proportional directional valve 4 and the sequence valve 6, and meanwhile, the oil in the oil cylinder plug cavity returns to the oil tank through the hydraulic control one-way valve 8, so that the oil cylinder rod lifting return process is realized.
Due to the use of the sequence valve 6, the oil cylinder rod can be stably stopped at a lifting position, the downward sliding is avoided, and the safety is improved.
