| Forging hydraulic press is considered as one of the developing directions of forging press because of its fast forging speed, high control accuracy, high automatization, wide technology range, saving energy and material. It is a product replacing large type forge hammer and mesotype and minitype common forging water press.The development tendency of mechanical, electrical and hydraulic technology is integrated in this dissertation. To meet the demands of fast speed, reliability and stability, a kind of forging hydraulic press system with either high proportion of performance-price or good reliability and maintainability is developed. Theory and experiment are also investigated in this dissertation. Now the system is applied to actual production and is entered market.Based on the designs which are mechanical and hydraulic devices of hydraulic press and operation manipulator, The subject analysed The stability and rapid response of the hydraulic system, and according to the working process of hydraulic press, in accordance with the requirements of production technology match a programmable controller for automatic control. Make use of PLC its own the most advantages switches control with and the PTO control and PID control functions, The subject has researched the control of speed of the hydraulic press and hydraulic oil temperature. Given work flow chart the hydraulic press and program flow chart, and Programmed. At the same time, also has controlled the operation manipulator in use of PLC.This dissertation in depth study and master the PROFBIUS fieldbus technology, in view of the 60 MN wheel forging hydraulic press a wide range of control signals, and complexity, Considering system reliability, compatibility and scalability, selected the PROFIBUS-DP fieldbus. constructed joint control network of hydraulic press and operation manipulator and industrial Ethernet with the synchronization system network, Realized process of production automation, intelligent.
