The main program for this graduation design is to finish press process and the design of motorcycle tank pouring orifice. The press process of blanking，drawing, perforating, flaring, trimming are adopted. In this paper, the process suitability of part is analysed. The process parameters, such as blank layout and press force are calculated. The general construction of mold and main parts are designed. The compound die of blanking，drawing,perforating and the simple press tool of flaring,trimming and detail drawings of main parts are drawn.
