It is often used for pressing and pressing forming process, such as: forging, stamping, cold extrusion, straightening, bending, flanging, sheet metal drawing, powder metallurgy, pressing etc. Hydraulic drive system isa part of hydraulic machinery, hydraulic transmission system design to the overall design of the same host at the same time. To design, we must proceed from the actual situation, bination of various transmission forms, give full play to the advantages of hydraulic transmission, and strive to design hydraulic transmission system has the advantages of simple structure, reliable operation, low cost, high efficiency, simple operation, convenient repair. I am learning system of hydraulic system of technical knowledge, access to some of the relevant literature, on this basis, combined with the need to address my ideas and design work, the main work is described as follows: (1) the development of hydraulic press hydraulic principle diagram. (2) completed the design of hydraulic cylinder. (3) plete the design of hydraulic station. (4) were checked for the design of hydraulic system (5) pletion of the hydraulic press overall three-dimensional modeling
