上端蓋沖壓模具設(shè)計(jì)與制造 摘 要本設(shè)計(jì)題目為上端蓋零件沖壓成形工藝與模具設(shè)計(jì)，含有落料、彎曲、拉伸等工序，此設(shè)計(jì)體現(xiàn)了這類零件的設(shè)計(jì)要求、內(nèi)容及方向，具有一定的設(shè)計(jì)意義。通過對該零件模具的設(shè)計(jì)，進(jìn)一步加強(qiáng)了設(shè)計(jì)者沖裁模設(shè)計(jì)的基礎(chǔ)知識，為設(shè)計(jì)更復(fù)雜的沖裁模具做好了鋪墊和吸取了更深刻的經(jīng)驗(yàn)。本設(shè)計(jì)運(yùn)用沖壓工藝及模具設(shè)計(jì)的基礎(chǔ)知識，首先分析了工件的工藝要求，為選取排樣的類型做好了準(zhǔn)備；然后估算了板料的選取，便于導(dǎo)尺的寬度及確定排樣的方法；最后分析了工件的特征，確定模具的設(shè)計(jì)參數(shù)、設(shè)計(jì)要點(diǎn)及卸料裝置。本工件為薄板的落料、拉深件，但是工件的毛坯直徑較大，所以在選取壓力機(jī)時(shí)應(yīng)該注意，且鋼材料的屈服強(qiáng)度也較大。關(guān)鍵詞：沖裁模具 ；模具設(shè)計(jì)；落料；拉深；屈服強(qiáng)度；壓力機(jī) 上端蓋沖壓模具設(shè)計(jì)與制造 AbstractThis design of the maze is last hold cover parts stamping and die design process, containing Blanking, Bending, Drawing processes, This design reflects such parts design, content and direction, with a certain sense of design. Through parts mold design, further strengthening the designers Die basis for the design of knowledge, for the design of more complex stamping die has laid a good groundwork and learned a more profound experience. This design and use of die stamping process designed on the basis of knowledge, the first analysis of the technological requirements of the workpiece, To select the type of layout well prepared; then estimate the sheet metal selection, facilitate I. foot width and determine the layout; Finally, the workpiece characteristics, and the mold design parameters, Design and unloading devices. The workpiece for the blanking plate, drawing 'punch pieces, but the rough workpiece diameter larger, Therefore, in selecting press should pay attention to when and steel material yield strength is greater. Key words : Blanking die ;mold designing ；Drawing; yield strength; Press machine
