端蓋沖壓落料拉伸復(fù)合模具設(shè)計(jì),沖壓,拉伸,復(fù)合,模具設(shè)計(jì) 端蓋沖壓成形工藝及模具設(shè)計(jì) 摘要：設(shè)計(jì)著重介紹了工件的成型工藝及模具結(jié)構(gòu)設(shè)計(jì)。通過對(duì)工件的工藝分析，確定了工藝方案。并設(shè)計(jì)了一套正裝復(fù)合模具。在設(shè)計(jì)同時(shí)利用參考資料，確定了各工作零件的尺寸。并較多的考慮了模具結(jié)構(gòu)的調(diào)整性、易更換性及模具成本。同時(shí)在模具設(shè)計(jì)內(nèi)容中融匯了沖壓模具的不同加工方法、加工工藝及裝配工藝，對(duì)初學(xué)沖壓模具模設(shè)計(jì)者有一定的參考價(jià)值。本設(shè)計(jì)從模具設(shè)計(jì)到零部件的加工工藝以及裝配工藝等進(jìn)行詳細(xì)的闡述，并應(yīng)用CAD進(jìn)行各重要零件的設(shè)計(jì)。 關(guān)鍵詞： 復(fù)合模。 Lamp screen pressing formed technology and mold design Abstract: The design introduced emphatically the workpiece takes shape the craft, and mold structural design. Through to the workpiece craft analysis, has determined the craft plan. And has designed set of true things compound molds. Uses the reference during the design, has determined each work components size. And many considerations mold structure adjustment, easy replacement and mold cost. Meanwhile has blended together the ramming mold different processing method in the mold design content, the processing craft and the assembly craft, to begins studies the ramming mold mold designer to have the certain reference value. This design designs from the mold to the spare part processing craft as well as the assembly craft and so on carries on the detailed elaboration, and carries on each important components using CAD the design. Key words: the compound mold.  目 錄 1、緒論……………………………………………………………………………1 1.1 國內(nèi)模具的現(xiàn)狀和發(fā)展趨勢(shì)………………………………………………1 1.1.1國內(nèi)模具的現(xiàn)狀……………………………………………………………1 1.1.2國內(nèi)模具的發(fā)展趨勢(shì)………………………………………………………2 1.2 國外模具的現(xiàn)狀和發(fā)展趨勢(shì)………………………………………………2 2、沖壓工件的工藝分析…………………………………………………………5 2.1 零件工藝性…………………………………………………………………5 2.2 工藝方案的確定……………………………………………………………6 3、工藝性計(jì)算……………………………………………………………………7 3.1 計(jì)算毛坯尺寸………………………………………………………………7 3.2　排樣設(shè)計(jì)……………………………………………………………………7 3.3 條料寬度、導(dǎo)料板間距離和材料利用率的計(jì)算……………………………9 3.4計(jì)算凸、凹模刃口尺寸………………………………………………………9 3.41沖孔凸、凹模刃口尺寸的計(jì)算………………………………………………9 3.42 落料凸、凹模刃口尺寸的計(jì)算…………………………………………… 10 3..43拉深凸、凹模尺寸的計(jì)算……………………………………………………11 3.44拉伸凸、凹模的圓角半徑的計(jì)算……………………………………………12 3.5沖壓力得計(jì)算…………………………………………………………………12 3.51.落料力、沖孔力、卸料力、推件力…………………………………………12 3.52.拉深力…………………………………………………………………………12 3.53.壓邊力…………………………………………………………………………13 3.54.頂件力…………………………………………………………………………14 4、模具工作部分的設(shè)計(jì)…………………………………………………………15 4.1落料凸、凹模的結(jié)構(gòu)設(shè)計(jì)……………………………………………………15 4.2沖孔6.5的凸模設(shè)計(jì)………………………………………………………15 4.3模柄……………………………………………………………………………15 4.4墊板……………………………………………………………………………16 4.5凸模固定板……………………………………………………………………16 4.6凸凹模固定板…………………………………………………………………17 4.7落料凹模………………………………………………………………………17 4.8卸料板…………………………………………………………………………18 4.9頂件塊 ………………………………………………………………………19 4.10凸凹?！?0 4.11模具其它部件的選用…………………………………………………………20 4.12選用模架、確定閉合高度及總體尺寸………………………………………21 4.13.沖壓設(shè)備的選擇………………………………………………………………22 5、模具的裝配……………………………………………………………………24 5.1模具總裝圖……………………………………………………………………25 結(jié)束語………………………………………………………………………………26 致謝 ………………………………………………………………………………28 參考文獻(xiàn)……………………………………………………………………………29
