摘要
本說(shuō)明書在所要加工零件的基礎(chǔ)上，經(jīng)過(guò)仔細(xì)的論證和計(jì)算，完成了本次畢業(yè)設(shè)計(jì)題目的相關(guān)內(nèi)容。由于此次加工零件的加工工藝復(fù)雜，所以不能用一套模具來(lái)完成零件的加工，要單獨(dú)設(shè)計(jì)兩套模具，一套落料沖孔模、一套翻邊成型模。由于模具尺寸較大且不對(duì)稱，模具的模座和沖頭等不是標(biāo)準(zhǔn)件，要另行設(shè)計(jì)。在模具設(shè)計(jì)過(guò)程中，主要進(jìn)行了上下模座的設(shè)計(jì)，上下墊板的設(shè)計(jì)，落料和沖孔部分的設(shè)計(jì)，刃口尺寸的設(shè)計(jì)及計(jì)算，翻邊部分的設(shè)計(jì)及計(jì)算，沖裁力的計(jì)算，翻邊力的計(jì)算，壓力機(jī)的選擇，相關(guān)標(biāo)準(zhǔn)件的選擇，考慮加工的工藝性等。因被加工的零件窄且長(zhǎng)，成形、翻邊時(shí)不易定位，可能使翻邊高度不均勻，在模具設(shè)計(jì)完成后根據(jù)實(shí)際加工情況，重新調(diào)整板料的尺寸和外形才可以正常加工。在模具設(shè)計(jì)過(guò)程中，運(yùn)用CAD技術(shù)進(jìn)行模具結(jié)構(gòu)設(shè)計(jì)和零件圖紙的繪制?？紤]模具整體制造難度較大且整體重量較大，整副模具將增加制造和安裝的難度，經(jīng)過(guò)經(jīng)驗(yàn)及相關(guān)計(jì)算，可以使用組合分體模具完成該模具的全部制造。

關(guān)鍵字：模具、落料沖孔、翻邊成型、標(biāo)準(zhǔn)件。

Abstract
This instruction booklet in must process the components in the foundation, after careful proof and computation, has completed this graduation project topic related content. Because this processing components craft is complex, so we can not use a die to complete the processing of this parts, must alone design two sets of dies, a cutting punched hole die, a upsiding down edges die. Because the mold size is big also is asymmetrical, the die base and punch is not a standard hardware, must separate design. In die design process, mainly process project on the punch set, die set, punch pad, die pad, pierce, forming , tool point  design and size calculation, upsiding down edgesof the design and calculation, stamping power calculation, upsiding down edges power calculation, hydraulic machine select, Related standards of standard parts atc. Because the components processes is been narrow also is long, bending and upsiding down edges not positioning, In die design based on the actual completion of the processing, readjusts the sheet size and the contour only then may process normally. In die design process, exertion CAD structural design and layout for the parts drawings. Consider a molding tool a whole manufacturing a difficulty bigger and whole weight to compare greatly, the whole molding tool difficulty of increment manufacturing and fixing, through experience and the related calculation, can use a discrete molding tool of combination to complete all manufacturings of this mold tool.
