Abstract：

Some typical application examples of AC servo mechanical press in metal volume forming were introduced, and some new forming processes, which were impossible on common mechanical presses, were realized by special moving slider and loading modes. Then, the backward extrusion of magnesium box was conducted by combining control of movement and force, and the cold forming (flat plate forging, deep hole extrusion, extrusion of inner spline) without surface treatment was done by pulsing loading to improve lubrication. Furthermore, the gear extrusion accuracy was improved by the variable speed extrusion to eliminate temperature effects. At the same time, the integration control of press and auxiliary equipments was processed by the high automation of mechanical press to increase the automation and intellegency of production, the die forging productivity was enhanced by optimizing the slide motion and system integration, and the automated free forging was realized by the integration of press and robot. Thus, the combination of research and development of equipment and applied technology was the only way to promote technological innovation and get out of the “introduction-backward-reintroduction” infinite loop.
