Abstract：

A control system based on industrial personal computer (IPC) and Siemens high performance motion controller Simotion was researched and implemented. According to main transmission system of servo press, it was applied that the structure type of servo motor-worm and worm gear commutation reducer-transmission screw-multi-link force increasing mechanism. The displacement and velocity relationships between nut and slider were researched by MSC.ADAMS software, and velocity-displacement curve inputted by user was transformed into that of nut. Based on the thought of modular design, upper computer software was developed by C# language, and lower computer software was developed by IEC61131-3 structured text (ST) language. Upper computer and lower computer were communicated with each other by UDP protocol. The system has been successfully applied to a self-developed 2000 kN mechanical multi-link servo press in a production line of hot forming technology with CNC heating furnace and ABB robot for more than one year. The result shows that the system is stable and reliable, and it extends the technical application scope of traditional press, and improves product quality.
