 摘要
 本次課題打火機(jī)金屬外殼的冷沖壓模具設(shè)計，通過這次設(shè)計，進(jìn)一步熟悉沖壓模具的設(shè)計流程運(yùn)用落料、沖孔、彎曲等沖壓工序設(shè)計冷沖壓成形模具，需要解決很多的關(guān)鍵問題，對零件進(jìn)行工藝分析，進(jìn)行沖壓工藝方案及模具結(jié)構(gòu)方案設(shè)計和對沖壓模具零部件工藝參數(shù)進(jìn)行參數(shù)選擇及驗算，繪制沖壓模具裝配圖和零件圖。需要運(yùn)用機(jī)械、材料成形、冷沖壓模具、計算機(jī)二、三維設(shè)計等多學(xué)科的知識，需要相當(dāng)廣闊的知識面和較高的專業(yè)水平。通過對零件進(jìn)行工藝分析和工藝參數(shù)計算，根據(jù)零件所需冷沖壓工序設(shè)計出連續(xù)沖壓模具，同時運(yùn)用AutoCAD繪制二維模具裝配圖和零件圖還得同時對部分零件進(jìn)行了加工工藝分析。該零件復(fù)雜且尺寸不規(guī)則，這對模具設(shè)計和展開排樣提出了較高的要求，特別是彎曲過程，需要合理的安排工藝，巧妙的設(shè)計沖模來解決，對于部分不關(guān)鍵的零件可適當(dāng)降低尺寸公差要求，設(shè)計中盡可能使用標(biāo)準(zhǔn)件，有利于設(shè)計成本的降低。

 Abstract
 This topic lighter metal exterior cold stamping mould design, through the design, further stamping mould design process using blanking, punching, bending stamping process design of cold stamping mould, needs to solve the key problems of many parts, technical analysis, stamping process scheme and the die structure and design of stamping mould parts process parameters parameter selection and calculation, stamping, assembly and detail drawings. Need to use machines, materials, stamping, molding, cold, 3d design of computer science knowledge, need quite a broad knowledge and professional level. Through the analysis of the technology of parts and the process parameters calculation, cold stamping parts needed to process a compound stamping mould design, and using AutoCAD assembly drawing two-dimensional mould parts and also have also made for parts processing analysis. The components and complex, the size of irregular of mold design and layout puts forward higher requirements, especially the bending process, need reasonable arrangement of the clever design process, stamping parts, to solve the key parts for not properly reduce dimension tolerance requirement,design as far as possible, to use standard design cost reduction.
