Single process model refers to only one station, only to plete the process of punching die, it can be divided into the blanking die, bending die, stretching mold, turn over the hole pattern and plastic mould etc. Single process model is a simple, precision stamping die, many advantages such as high precision and high service life, applicable to production of various kinds of stamping industry. Single process theories of stamping die, stamping technology and die design and manufacturing, and many key technologies in mould material. Therefore, from the aspects of technical prehensive study of single process model is very meaningful. Will support the connection plate is analyzed the design of single working procedure of mold design process, introduced the forming of the layout, single working procedure of mold parts design. Determined the reasonable forming steps and the process model of the structure, the design scheme is first blanking, punching, bending, after the last flush again punching. Keywords： Single Die process design punching 重慶理工大學(xué)論文 支撐連接板沖壓工藝及模具設(shè)計 1 緒論 沖壓是使板料經(jīng)分離或成型而得到制件的加工方法。常溫下進行的板料沖壓加工稱為冷沖壓。 模具可保證沖壓的尺寸精度，使產(chǎn)品質(zhì)量穩(wěn)定，而且在加工中不破壞產(chǎn)呂表面。 現(xiàn)代的制造工業(yè)的發(fā)展和技術(shù)水平的提高，很大程度上取決于模具工業(yè)的發(fā)展。一般壓力機加工，一臺普通壓力機設(shè)備每分鐘可生產(chǎn)零件幾件 到幾十件，高速壓力機生產(chǎn)率已達到每分鐘數(shù)百件甚至上千件。顯而易見，模具作為一種專用的工藝裝備，在生產(chǎn)中的決定性作用和重要地位漸為人們所共識。 20世紀模具生產(chǎn)得到了進一步的發(fā)展，在此期間歸納出的模具設(shè)計原則上，使得壓 力機械、沖壓材料、加工方法、模具結(jié)構(gòu)、模具材料、模具制造方法、自動化裝置等領(lǐng)域面貌一新，并向?qū)嵱没姆较蛲七M。其代表是五十多個工位的級和十幾個工位的多工位傳遞模。當(dāng)前國際上計算機輔助設(shè)計（ CAD）。 三維 CAD 技術(shù)的出現(xiàn)，極大地推動了模具工業(yè)的發(fā)展，使零件設(shè)計及模具結(jié)構(gòu)設(shè)計在非常直觀的三維環(huán)境下進行，模具設(shè)計完成后，可根據(jù)投影 關(guān)系自動生成工程圖。同時，三維 CAD
