A practical technological process has been worked out. Relatively simple structures of the dies have been designed and qualified parts have been manufactured with dies. The design and manufacture for the pound tools of blanking and drawing is introduced in detail. The second drawing die and a pound tools of pierce and trim are also introduced,including determination of the operation sequence and operation position parts’ dimensions. The first thing to design the press dies is the analysis and lots of calculation for the grease cup with taper on basis of stamping technological process. The election of press process is based on consulting correlation datum and analyzing the form of manufactured product meticulous。 The election of press die is based on synthesis considerations on economical efficiency、the processing property of part and plex degree are many factors。 Calculating the work blank of manufactured product unfold dimension is lined feed on the premise of calculation convenience but without contribution die confectioning simplified frequent application cast. In the text ,to introduce the election principle and means of press confectioning art and miscellaneous rapport part, otherwise also introducing calculation means on the work blank form of many kinds of product unfold dimension and simplified cast, and the means of looking up on the reference books of designing press die . 【Key words】grease cup, die design, drawing, stamping technological process,The unfold dimension of the work blank 改革開放以來,隨著國民經(jīng)濟的高速發(fā)展,市場對模具的需求量不斷增長。近年來,模具工業(yè)一直以15%左右的增長速度快速發(fā)展,模具工亞企業(yè)的所有制成分也發(fā)生了巨大變化,除了國有專業(yè)模具廠外,集體、合資、獨資和私營業(yè)得到了快速發(fā)展。浙江寧波和黃巖地區(qū)的“模具之鄉(xiāng)”;廣東一些大集團公司和迅速崛起的鄉(xiāng)鎮(zhèn)企業(yè),科龍、美的、康佳等集團紛紛建立了自己的模具制造中心;中外合資和外商獨資的模
