It has the feature of simple operation, high accuracy, product consistency, high production efficiency, high utilization of materials and for mass production and so on. The graduation project bases on the pieces（binaural washer）of punch set that have been identified in binaural washer dimensions for analysis and design of the craft of punch set resulting in getting the craft of punch. I will do the job of calculation and design of structural parameters punch basing on the craft of punch set that has been determined，and ultimately determine the progressive of punch structure of Progressive Die according to the literature. I select the standard parts and the mold according to the designed structure of punch structure .Thus completing the mold design. After the completion of mold design, I use UG software to complete three-dimensional model and use AutoCAD software to complete the graphics of mold assembly drawing. The graduation project is independently complete not less than40,000 characters of the specified English translation associated with professional. Through this graduation design, I learn systematically and mastered the preparation of technical of manufacturing process and knowledge of mold design. I used the advanced design concepts and design methods, and I successfully complete the graduate design of Binaural Washer Punching and Blanking Progressive Die Design.Key words : design; process analysis; stamping die; progressive die; structural calculations.目 錄引言11 沖載件的工藝性分析21.1 沖載件21.1.1沖載件材料的選擇21.1.2沖載件結(jié)構(gòu)分析21.1.3沖載件尺寸精度21.2 沖載模的選擇31.2.1方案一 單工序模生產(chǎn)31.2.3方案二 復(fù)合模生產(chǎn)31.2.3方案三 級(jí)進(jìn)模生產(chǎn)32 沖載工藝設(shè)計(jì)42.1 排樣方式的確定及計(jì)算42.1.1搭邊值的確定42.1.2確定排料方向42.1.3計(jì)算送料步距A52.1.4計(jì)算料條寬度B52.1.5排樣圖52.1.6計(jì)算材料的利用率62.2 級(jí)進(jìn)模壓力中心的建立72.3 沖載力的計(jì)算92.3.1 沖孔力102.3.2 落料力102.3.3 沖載力102.3.4 卸料力、推件力和頂件力102.3.5 壓力機(jī)的選擇113級(jí)進(jìn)模設(shè)計(jì)123.1 凸、凹刃口尺寸計(jì)算123.1.1 沖孔時(shí)凸、凹模刃口尺寸的計(jì)算123.1.2對(duì)于落料時(shí)凸、凹模刃口尺寸的計(jì)算123.2 凸、凹模外形尺寸計(jì)算及確定143.2.1沖孔及落料凸模外形尺寸計(jì)算及確定143.2.1沖孔及落料凸模外形尺寸計(jì)算及確定164 級(jí)進(jìn)模主要零件設(shè)計(jì)174.1 級(jí)進(jìn)模模架的設(shè)計(jì)174.2級(jí)進(jìn)模模柄的設(shè)計(jì)184.3 級(jí)進(jìn)模墊板的設(shè)計(jì)194.4 凸模固定板的設(shè)計(jì)204.5 彈性卸料板設(shè)計(jì)214.6 導(dǎo)料板的設(shè)計(jì)234.7 標(biāo)準(zhǔn)圓柱銷和內(nèi)六角圓柱螺釘?shù)倪x擇234.8 級(jí)進(jìn)模導(dǎo)柱和導(dǎo)套的選擇254.9 級(jí)進(jìn)模校核265 級(jí)進(jìn)模零件材料的選擇275.1 級(jí)進(jìn)模凸模選材275.2 級(jí)進(jìn)模凹模選材285.3 級(jí)進(jìn)模上、下模座選材285.4 級(jí)進(jìn)模導(dǎo)柱和導(dǎo)套選材285.5 級(jí)進(jìn)模其他零件的選材295.5.1級(jí)進(jìn)模墊板、導(dǎo)料板和卸料板選材295.5.2 級(jí)進(jìn)模凸模固定板選材296 級(jí)進(jìn)模主要零部件的加工工藝306.1 凸模加工工藝306.1.1圓形凸模加工工藝306.1.2非圓形凸模加工工藝307 級(jí)進(jìn)模的UG建模和autoCAD制圖31總結(jié)33謝 辭34參考文獻(xiàn)35附 表362引言隨著我國(guó)經(jīng)濟(jì)快速發(fā)展的拉動(dòng)和我國(guó)產(chǎn)業(yè)政策的正確引導(dǎo)下，模具行業(yè)得到了快速的發(fā)展。近年來，隨著模具行業(yè)的結(jié)構(gòu)調(diào)整，我國(guó)模具行業(yè)的模具產(chǎn)品向著更大型、更精密、更復(fù)雜和更經(jīng)濟(jì)快速方向發(fā)展。我國(guó)模具行業(yè)的發(fā)展不僅為我國(guó)經(jīng)濟(jì)快速發(fā)展做出貢獻(xiàn)還為世界制造業(yè)做出貢獻(xiàn)?，F(xiàn)在，模具制造中的冷沖壓加工已經(jīng)是一種成熟的金屬加工方法。因此，冷沖壓模具的設(shè)計(jì)就很有必要。但是，冷沖壓模具的設(shè)計(jì)尤其是對(duì)于相對(duì)復(fù)雜的冷沖壓模具來說，設(shè)計(jì)時(shí)需要很強(qiáng)的想象力和創(chuàng)造力。對(duì)于模具設(shè)計(jì)者和制造者來說，模具設(shè)計(jì)理論、模具設(shè)計(jì)經(jīng)驗(yàn)和模具設(shè)計(jì)創(chuàng)新是不可或缺的。為了設(shè)計(jì)出擁有自主知識(shí)產(chǎn)權(quán)、適合我國(guó)國(guó)情、具有較高水平的模具，設(shè)計(jì)者和制造者必須不斷學(xué)習(xí)模具設(shè)計(jì)與制造的最新知識(shí)并且要敢于不斷創(chuàng)新。我國(guó)現(xiàn)在已經(jīng)擁有了大量的模具標(biāo)準(zhǔn)件，包括模具、導(dǎo)向件，推桿等標(biāo)準(zhǔn)件，這為實(shí)現(xiàn)我國(guó)模具行業(yè)快速健康發(fā)展提供可能。同時(shí)，因?yàn)橛休^大產(chǎn)量模具標(biāo)準(zhǔn)件的存在，使得我們的模具設(shè)計(jì)的周期縮短并為設(shè)計(jì)出更精密更大型的模具提供可能。結(jié)合我大學(xué)期間所學(xué)知識(shí)以及實(shí)踐所得經(jīng)驗(yàn)，本次設(shè)計(jì)就是在這樣的背景下進(jìn)行的。本次設(shè)計(jì)在為期十六周的時(shí)間里順利完成。1 沖載件的工藝性分析1.1 沖載件1.1.1沖載件材料的選擇由于此次設(shè)計(jì)的沖載件是雙耳止動(dòng)墊片，根據(jù)機(jī)械設(shè)計(jì)手冊(cè)1中冷沖壓零件推薦用鋼和鋼鐵材料的分類及技術(shù)條件的綜合比較，可以選擇本次畢業(yè)設(shè)計(jì)的雙耳止動(dòng)墊片的原材料為A2，即304不銹鋼。根據(jù)機(jī)械設(shè)計(jì)手冊(cè)1可知，A2的抗拉強(qiáng)度范圍為340520MPa。根據(jù)設(shè)計(jì)經(jīng)驗(yàn)，對(duì)塑性材料：剪切應(yīng)力極限 =(0.6一0.8)*抗拉極限；對(duì)脆性材料：剪切應(yīng)力極限 =(0.81.0)*抗拉極限。所以可以取材料的抗剪切值為。
