Abstract：850 tons ultra-large intelligent powder forming machine is mainly composed of main body mechanical structure and transmission system, main control system and servo feeding system, which can realize the forming of complex structural parts with nominal pressure of 8 500 kN. The structural design process and technical characteristics of 850 t ultra-large intelligent powder forming machine were described from seven aspects including the main technical indexes and precision requirements, the structural design and analysis of key parts, the structural design of the main transmission part, the structural design of the upper sliding column part, the design of the servo feeding mechanism, the design of the intelligent system of forming process parameters and the design of the remote fault intelligent diagnosis expert system. The optimization design and analysis process of the whole machine structure of ultra-large intelligent powder forming machine were emphatically elaborated, and the automatic and intelligent control system was integrated into the design to improve the design capability and technical level of self-designed ultra-large powder forming equipment.
