Abstract：

The current technical status of fast forging hydraulic press was briefly introduced, and the technical characteristics of its host structures, hydraulic transmission systems, control systems and other aspects were analyzed. Then, the host structure is diversified mainly pre-stressed structures, all of which adopt adjustable plane guides, columns and cross beams adopt flat-joint or plug-in structures, and main cylinders mostly adopt double-ball hinge flange connections. The transmission form of hydraulic system is standardized, forming three typical hydraulic transmission forms, namely, the valve control system composed of high-frequency response proportional valves and servo forging valves, and the pump control system composed of a sinusoidal pump. The control system is standardized and adopt on-site network control systems composed of Siemens controllers and industrial Ethernet network control system. Finally, the development trend of fast forging hydraulic presses was described in terms of green design, energy recovery, predictive maintenance, automatic forging and application of new technologies.
