Abstract：

The research status of fast forging hydraulic press at home and abroad was introduced, and deficiencies of the fast forging press in the domestic development were pointed out. The structures and principles of valve controlled hydraulic transmission system, pump controlled hydraulic transmission system and servo hydraulic transmission system were analyzed, and the advantages and disadvantages of these three kinds of hydraulic transmission system were pointed out on the above basis. Compared with valve controlled hydraulic transmission system and pump controlled hydraulic transmission system, servo hydraulic transmission system has the advantages of good servo performance, low cost, high processing quality and precision. Servo hydraulic transmission system is very suitable for fast forging hydraulic press. Finally, the characteristics of three different hydraulic transmission systems were summarized, and servo hydraulic transmission system was regarded as the main trend of development in fast forging hydraulic drive system.
