【正文】 塑，沖壓等模具的畢業(yè)設(shè)計(jì)，現(xiàn)有已做過(guò)的畢業(yè)設(shè)計(jì) 20 余套，都是答辯后能使用的，歡迎咨詢 qq419017882。 摘 要 近年來(lái)，我國(guó)工業(yè)的高速發(fā)展對(duì)模具工業(yè)，尤其是 冷沖 模具提出了越來(lái)越高的要求 。 我本次設(shè)計(jì)的工件采用的材料為 鋁 L3 及厚度為 2mm。合理排樣、減小廢料。完成一系列的計(jì)算后，畫出總裝圖、凸凹模配合圖等設(shè)計(jì)模具必備的圖紙。 進(jìn)行沖壓設(shè)計(jì)就是根據(jù)已有的生產(chǎn)條件，綜合考慮影響生產(chǎn)過(guò)程順利進(jìn)行的各方面因素，合理安排零件的生產(chǎn)工序，最優(yōu)地選用，確定各工藝參數(shù)的大小和變化范圍，設(shè)計(jì)模具，選用設(shè)備等，以使零件的整個(gè)生產(chǎn)過(guò)程達(dá)到優(yōu)質(zhì)，高產(chǎn)，低耗，安全的目的。 滑塊 。 復(fù)合模 東華理工大學(xué)長(zhǎng)江 學(xué)院畢業(yè)設(shè)計(jì)說(shuō)明書(shū) 目錄 Abstract In recent years, the rapid development of China39。 blanking。 pound die 東華理工大學(xué)長(zhǎng)江 學(xué)院畢業(yè)設(shè)計(jì)說(shuō)明書(shū) 目錄 目 錄 目 錄 ...................................................................................................................................................................3 1 緒論 ........................................................................................................................................................................1 工件材料的選取 ...........................................................................................................................................3 結(jié)構(gòu)形狀 .......................................................................................................................................................4 尺寸精度 .......................................................................................................................................................4 模具的技術(shù)要求 ...........................................................................................................................................4 3 確定工藝方案，模具形式及 模具結(jié)構(gòu)設(shè)計(jì) .....................................................................................................5 確定工藝方案，模具形式 ..............................................................................................................................5 模具結(jié)構(gòu)設(shè)計(jì) ...................................................................................................................................................6 4 縮口計(jì)算 ...............................................................................................................................................................7 縮口次數(shù)計(jì)算 ...............................................................................................................................................7 ...........................................................................................................................................7 縮口件的精度 ......................................................................................................................................8 卸料力的計(jì)算 ......................................................................................................................................9 4.. 壓力中心的確定及計(jì)算 ..................................................................................................................... 10 ....................................................................................................................... 10 ........................................................................................................................11 5 主要模具零件的加工工藝及設(shè)計(jì) .................................................................................................................. 12 縮口凹模加工工藝過(guò)程 ........................................................................................................................... 12 ................................................................................................................................ 13 沖孔凸模的加工工藝過(guò)程如下表： .................................................................................................................. 13 定位零件的設(shè)計(jì) ........................................................................................................................................... 13 推件裝置的設(shè)計(jì) ........................................................................................................................................ 14 6 模具閉合高度的計(jì)算 ......................................................................................
