In the production and life of machinery has been essential to the production of material to meet the needs of the mold. So the design and manufacture of the mould is very important. A country, the development of enterprises need to improve the level of mold technology, today's world mold technology level represents the level of development of today's industry. In the precision, complex, large-scale mold technology development is very rapid. The prospect of mold industry requires us to be more familiar with the professional knowledge, to become a professional talent to meet the needs of the market and more efforts. The graduation design is more important, this is not only a summary of their professional knowledge, but also a flexible application of professional knowledge to the actual production of a practice. This design is about the Xiali car differential bolt gasket. Xiali car differential bolt gasket by steel plate stamping processing, design and optimize the production process and stamping die design. The manufacture of bolts processed by tablets blanking punching die. Of course, this design for the blanking die design, through the analysis of the process to determine the type of mold and specifications. Design manual blanking mode, and then select the pressure gauge of the mold, and finally the mold of the equipment drawing out, according to the three-dimensional drawing with CAD drawing die 2D assembly drawing and part drawing. The role of differential bolt gasket is increases bolts and parts of the contact area, reducing wear, prolong the service life, stamping is relatively complex. Analysis the process need good toughness and strength, to prevent loosening in use. Punching gasket needs to design the mold, the analysis of practicality, economy and its production is simple, the production cost. Key words: Automobile gasket; stamping die; differential 目 錄 摘 要 i ABSTRACT ii 1 緒論 1 2 零件的工藝性分析 3 2.1 零件的總體分析 3 2.1.1外形落料的工藝性 3 2.1.3 沖裁件的孔邊距和孔間距 4 3 工藝方案的確定 4 4 排樣設(shè)計(jì)與計(jì)算 5 4.1 確定搭邊與搭肩值 5 4.2 確定零件的排樣方案 5 4.3 計(jì)算送料步距和條料的寬度 6 4.4 計(jì)算材料的利用率 6 5 選擇沖壓設(shè)備 7 5.1 沖裁力的計(jì)算 7 5.2 初選壓力機(jī) 8 5.3 確定壓力中心 9 6 模具結(jié)構(gòu)形式的選擇與確定 11 6.1 模具類型的選擇 11 6.2 定位方式的選擇 11 6.3 導(dǎo)向方式的選擇 11 6.4 卸料方式 11 6.5 送料方式 12 采用手動(dòng)送料。 12 7 模具工作零部件刃口尺寸的計(jì)算 12 7.1 沖裁孔的凸、凹模刃口尺寸的計(jì)算 12 7.2 外形落料凸模、凹模刃口尺寸的計(jì)算 12 模具主要零部件設(shè)計(jì) 14 7.3 工作零部件的結(jié)構(gòu)設(shè)計(jì) 14 8.1.1 落料凸凹模的設(shè)計(jì) 14 8.1.2 沖孔凸模的設(shè)計(jì) 15 8.2 定位裝置的設(shè)計(jì) 17 8.2.1 擋料銷及導(dǎo)料銷的設(shè)計(jì) 17 8.2.2 擋料銷與導(dǎo)料銷位置的確定 17 8.3 卸料裝置的設(shè)計(jì) 17 8.3.1 彈性卸料板的結(jié)構(gòu)形式 17 8.3.2 卸料螺釘?shù)倪x用 18 8.3.3 卸料彈簧的設(shè)計(jì)及選用 18 8.4 推件裝置的設(shè)計(jì) 18 8.4.1 剛性推件裝置的設(shè)計(jì)與標(biāo)準(zhǔn)化 19 8.4.2 推件塊的設(shè)計(jì) 19 8.4.3 連接推桿的選用 19 8.4.4 推板的設(shè)計(jì) 19 8.4.5 打桿的設(shè)計(jì) 19 8.5 支撐固定零件的設(shè)計(jì) 19 8.5.1 模架的選用 19 8.5.2 凸模固定板的設(shè)計(jì) 20 8.5.3 墊板的設(shè)計(jì) 20 8.6 導(dǎo)向零件的設(shè)計(jì) 20 8.7 緊固零件的設(shè)計(jì) 20 9 沖壓設(shè)備的的選用 21 10 模具總裝圖 21 結(jié)論 23 致 謝 24 參考文獻(xiàn) 25 4
