The topic of the paper is the main structure and transmission system design of 60MN forging hydraulic press. Based on hydraulic press design theory, referred the design experience and structure of former large-scale forging hydraulic press. And in view of existent flaw such as the lower efficiency, lower forging precision and the poorer anti-carries ability of the traditional hydraulic press structure, we define the new pattern of body structure. It offers preference for scheme demonstration and technical design of 60MN forging hydraulic press. In the paper, we analyze the main part of the hydraulic press such as hydraulic cylinder, upper beam, walking beam, lower beam, return cylinder and column. And we especially analyze hydraulic cylinder which is the key part of the hydraulic press. And discuss the influence of the bolt hole on the flange to equivalent stress on the flange transition region. At the same time, we give the design process of transmission system (hydraulic system) of the hydraulic press.
