【正文】 le was determined. After determining the preliminary design plan of the hydraulicpress machine, the traditional methods was used to design and examination the body of hydraulicpress machine .The 2D and 3D graph about the topbeam, lowerbeam, active beam, goes against the cylinder, the column, the final assembly drawing were draw by using the software of AutoCAD. At the same time, producing the manual of the hydraulic system, and analyzing the feasibility of it. Finally, a total analysis to the whole design was done, and the result that the whole design was feasible.
