The structure characteristics of the pump impeller were analyzed, and calculated the expanding dimension of this parts, determined pressing forming process of the pump impeller and dimensions of each working procedure, and described the structure design of whole sets of dies in detail, And on that basis determine the structure and size ofthe impeller stamping die specific parts. To maximize production efficiency and reduce production costs in the production of qualified on the basis of parts. Main introduction of this text leaf round project of basic work preface for spare parts washing pressing take shaping should including; The craft counts the calculation; Molding tool construction design, size...etc. Key words: pump impeller; pressing process; die design;
