Mechanical servo press technology for metal forming

摘要

Recently several press builders developed gap and straight-sided metal forming presses that utilise the mechanical servo-drive technology. The mechanical servo-drive press offers the flexibility of a hydraulic press (infinite slide (ram) speed and position control, availability of press force at any slide position) with the speed, accuracy and reliability of a mechanical press. Servo drive presses have capabilities to improve process conditions and productivity in metal forming. This paper reviews the servo press designs, servomotor and the related technologies, and introduces major applications in sheet metal forming and bulk metal forming.
