Hydraulic presses are metal forming machines which can complete various forging technology such as alignment, cold forging, cold extruding and so on. Hydraulic presses have many structural forms but more often than not they are composed of crossbeam, vertical post, work table, slide block and ejector parts. This paper is about the design of 100T hydraulic press's hydraulic system, though the condition analysis of the hydraulic press's main cylinder and ejection cylinder, we can draw their velocity diagrams and load diagrams. Then we choose basic hydraulic circuit to form the hydraulic system schematics. We must make sure the main cylinder can complete the basic working cycle of fast descending, deceleration repression, time delay of press forming, relinef-pressure return and stop, and on the other hand, ejection cylinder can realize the action of ejection, return and floating side pressing. After that, we must analyse the control process of the hydraulic system. Hydraulic system's main parameters are determined and through the analysis and calculation of pressure, flow and other parameters, and then we can go on the choose hydraulic components and auxiliary parts such as pump , motor, filters, control valves. This design adopted the manifold block, and except that the connection of pump and hydraulic cylinder still uses the pipes and pipe joints, the connection of other components all through the channel of the manifold block. Its structure is more compact, volume is relatively smaller, its weight is lighter without pipe connection. What's more, it can eliminate leakage of tubing, connectors, vibration and noise, also, the installation, commissioning and maintenance of hydraulic systrem are convenient, low pressure drop, and it looks more beautiful.The paper has also designed the overall layout of the hydraulic station.what is more this paper have three-dimensional graph of integrated block, hydraulic pressure station, which make it more beautiful and accessible to reader. The hydraulic system can meet the press order cycle action requires and realize the plastic material forging press, stamping cold extrusion, straightening, bending forming process and other contour machining technic through check calculation of hydraulic system pressure loss and the temperature of the hydraulic system.
