Hydraulic technology isone of the fastest growing technology in mechanical equipment. Especially with the microelectronics, bination puter technology in recent years, so that the hydraulic technology has entered a new stage of development. Press slider drivens by the hydraulic cylinder, hydraulic parts used for punching processing, can realize the rapid decline ofa slider punching down a stop rapid rise ina working cycle. Stamping technology is currently being one of the metal pressure processing method is widely used, it has the characteristics of high efficiency, good quality, energy saving, low cost, so the use of stamping technology more and more advanced industrial countries instead of cutting and other processing technology. Stamping technology is widely used in automobile, agricultural machinery, household appliances, electronic instruments, the defense industry and daily necessities such as production department. In recent years, hydraulic stamping press in improving stroke times fast technology, precision technology, active anti offset to improve the performance and reduce noise at lower cutting damping technology, energy saving hybrid drive technology installed power and synchronization technology multi-point pressure and sliding block position and transmission of NC technology progress soon, the past hydraulic and mechanical press parison of ings is almost gone. Stamping processing equipment in the traditional, technical performance, and
