Abstract：

The structure, main performance parameters and operating requirement of hot die forging hydraulic press were introduced, a slider action circuit was designed and the working principle of its constitution was detailed discussed. The two-port cartridge valve was used as integrated control valve block circuit to control the flow direction, pressure and flow of oil, which has merits of small flow resistance, quick response, less leakage, opening and closing characteristics and good overload protection performance. The proportion of flexible pressure relief technology was used to slowly adjust the setting pressure of proportional overflow valve to be 0 according to a certain curve, which can unload pressure, thereby, the compressor runs smoothly, and the vibration and noise reduce. A double valve supporting valve group was used to prevent the slider bearing failure, and there was reliable pressure safety device, so that the slider action was reliable and stabile. Each control valve acts with order to achieve stepless programmable control of slider with 0-15 mm·s-1 working speed and compressor efficiency can get to 40 s to complete a pressing cycle, which meet the requirements of equipment use and various performance parameters. Practice proves that the design is reasonable, performance is reliable, and it can be used in related industries.
