【正文】 止動片沖壓工藝分析及模具設(shè)計(jì) 1 摘 要 本設(shè)計(jì)是對給定的模具產(chǎn)品圖進(jìn)行沖壓模 工藝分析和 模具設(shè)計(jì)，在綜合考慮了經(jīng)濟(jì)性、零件的沖壓工藝性以及復(fù)雜程度 和精確度 等諸多因素的基礎(chǔ)上進(jìn)行沖壓工藝分析與計(jì)算的，并提出了合理的工藝方案 和結(jié)構(gòu)形式 ，介紹了模具設(shè)計(jì)中的排樣與送料方式和卸料與導(dǎo)向方式，討論了主要工作件間隙的確定和刃口尺寸及沖壓力 的計(jì)算， 并選擇合適的壓力機(jī)，設(shè)計(jì)中主要對 模具 工作部分尺寸進(jìn)行計(jì)算和 主要零部件的設(shè)計(jì) 以及 加工工藝的制定。 該模具提高了制件質(zhì)量和生產(chǎn)效率，降低了模具成本，制件質(zhì)量符合生產(chǎn)要求。 關(guān)鍵詞 ：復(fù)合模 工藝分析 沖孔 落料 止動片沖壓工藝分析及模具設(shè)計(jì) 2 Abstract This design is to the product chart which assigns carries on flushes the die mold design and mold design process analysis. In the overall evaluation efficiency, the ponents ramming technology capability as well as the plex degree and accuracy and so on in many factor foundations carried on the ramming craft analysis and the putation, a reasonable process was proposed. The blanking layout and feeding styles, unloading way and guiding method were introduced, and the main ponents of the mold design and process technology development .The determination of the clearance between working parts and the calculation of punching and blanking pound die were expounded. This pound die improved product qualities and production efficiency with lower costs. The reliable product quality is achieved. Key words: Compound Die。 Process Analysis。 Punching。 Blanking 止動片沖壓工藝分析及模具設(shè)計(jì) 3 目 錄 引言 ........................................................................................................................... 5 1 止動片沖壓工藝分析及模具設(shè)計(jì) ................................................................ 9 設(shè)計(jì)題目設(shè)計(jì)一止動片，零件圖如下 :.....................................................9 沖壓件工藝分析 ..........................................................................................9 沖壓工藝方案的確定 ..................................................................................9 模具結(jié)構(gòu)形式的確定 ................................................................................10 排樣設(shè)計(jì) ....................................................................................................10 沖壓力的計(jì)算 ............................................................................................12 沖壓力 ............................................................................................ 12 卸料力 ............................................................................................ 13 頂件力 ............................................................................................ 13 模具總沖壓力為 ............................................................................ 13 壓力中心的計(jì)算 ........................................................................................ 13 初選壓力機(jī) ................................................................................................ 15 2 模具總體設(shè)計(jì) ................................................................................................... 15 模具類型的選擇 ........................................................................................ 15 定位方式的選擇 ........................................................................................ 16 卸料方式的選擇 ........................................................................................ 16 出件方式 .................................................................................................... 16 確定送料方式 ............................................................................................ 16 導(dǎo)向方式的選擇 ........................................................................................ 16 3 模具工作部分尺寸計(jì)算 ................................................................................ 17 工作零件刃口尺寸計(jì)算 ........................................................................... 17 沖載間隙分析 ................................................................................ 17 落料模具工作零件刃口尺寸計(jì)算 ............................................... 18 沖孔模具工作零件刃口尺寸計(jì)算 ................................................ 18 ................................................................... 19 卸料塊的設(shè)計(jì) ............................................................................... 19 彈性元件橡膠的設(shè)計(jì) .................................................................... 20 4 主要零部件設(shè)計(jì) .................................................................... 錯誤 !未定義書簽。 工作零件的結(jié)構(gòu)設(shè)計(jì) ................................................................................ 22 凸凹模 ............................................................................................ 22 落料凹模 ........................................................................................ 22 沖孔凸模 ........................................................................................ 25 其它模具零件結(jié)構(gòu)尺寸 ............................................................................ 28 卸料板的設(shè)計(jì) ................................................................................ 28 止動片沖壓工藝分析及模具設(shè)計(jì) 4 墊板設(shè)計(jì) ........................................................................................ 29 固定板設(shè)計(jì) .................................................................................... 31 模架的選用 ............................................................................................... 33 上、下模座的設(shè)計(jì) ........................................................................ 33 導(dǎo)柱、導(dǎo)套及模架的選用 ............................................................ 34 其它標(biāo)準(zhǔn)零件的選用 ................................................................................ 37 模柄的選用 .................................................................................... 37 導(dǎo)料銷 ............................................................................................ 38 卸料螺釘?shù)倪x用 ............................................................................ 38 定位零件 ........................................................................................ 38 推件裝置 .................................................................................
