Abstract：

The most outstanding advantages of servo mechanical presses are intelligence, high efficiency and energy saving, and they combine the characteristics of hydralic presses and mechanical presses with fast action, pausing with pressure at any position and controlling slider motion by proggraming. Therefore, it is a powerful tool for developing new forming processes. Then, some typical application examples of servo mechanical presses at home and abroad in
sheet metal forming were introduced including servo mechanical presses stamping production line for large automabile panels, hot stamping production line for ultrahighstrength steel plate by servo mechanical presses, highquality green blanking process, fine bending, highefficiency drawing, hot stamping of magnesium alloy sheet, etc. Furthermore, a new forming process that could not be completed on a common mechanical press was realized by designing the special motion mode of slider, and some views on how to accelerate the application of servo forming technology were pointed out. Thus, while strengthening the research of new equipment technology, the application technology research based on new equipment might also be strengthened.
