摘要：

论述了伺服液压机的国内外发展现状，重点介绍了125 t混合伺服液压机设计的基本原理、结构特性、技术方案和应用。125 t混合伺服液压机采用高级微处理器控制系统，将压力信号、位置信号进行处理，形成闭环系统，实现交流伺服电机驱动的内啮合齿轮泵流量的精确控制；充液阀采用比例伺服恒压控制技术，极大提高了充液阀的开启速度、稳定性和可靠性，减小液压冲击，实现液压系统的混合伺服控制。机架采用高刚度设计标准，有效防止系统释压时机架反弹造成精密成形位置漂移。液压系统多处采用安全冗余设计，提高安全级别。电控系统集成了德国福伊特、德国西门子、力士乐等多家国际知名企业的控制技术。125 t混合伺服液压机具有高速高效、高精度、高柔性、节能环保、低噪音、无级调速，可在全行程任意位置控制输出压制力的特性。该压机可以广泛应用于精密件定程定压成形、拉延成形、提高单次成形深度、冲裁工艺及新材料成形工艺等。

The current situation of servo hydraulic press at home and aboard was discussed and the basic principle, characteristics, technical solutions and applications of 125 t hybrid servo hydraulic press were mainly introduced. Advanced microprocessor control system is adopted by 125t hybrid servo hydraulic press to process the pressure and position signal to form a closed loop system and realize a precise control on the flow outputted from internal gear pump which is driven by the AC servo motor could be realized. The control technology of proportional servo with constant pressure which greatly improves the opening speed, stability and reliability, while reduces the hydraulic impact, and forms the hybrid servo hydraulic control of the hydraulic system. The frame of hybrid servo hydraulic press is of adopts high-stiffness design standards to effectively prevent the precise forming position from drifting caused by the frame rebound during pressure releasing. Safety redundancy design was adopted by the hydraulic system to improve the level of security. The electrical control system integrates control technologies from many famous enterprises such as the German Voith, Siemens and Rexroth. 125t hybrid servo hydraulic press has properties of high speed, high efficiency, good precision, strong flexibility, energy conservation and environmental friendly, low noise, and ram speed stepless adjustment and it can also output the required press force at any position during the whole stroke. It is comprehensively applied in fields such as precise parts deformed at fixed pressure and position, deep drawing, improveing the single forming depth, blanking and new material forming process, etc..
