摘要：

简要介绍了目前快速锻造液压机的技术现状，对其主机结构、液压传动系统、控制系统等方面的技术特点进行了分析：主机结构形式多样化，以预应力结构为主，均采用可调平面导向，立柱与横梁采用平接式或插入式结构，主缸多采用双球铰法兰连接等；液压系统传动形式模式化，形成了以高频响比例阀和伺服锻造阀组成的阀控系统，以及正弦泵组成的泵控系统3种典型液压传动形式；控制系统标准化，均采用西门子控制器及工业以太网组成的现场网络控制系统。此外，从绿色设计、能量回收利用、预测性维护、自动锻造以及应用新技术等方面对快速锻造液压机的发展趋势进行了阐述。

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.
