3365 上防塵蓋的沖壓成形工藝與模具設計,防塵蓋,沖壓,成形,工藝,模具設計 　　　 上防塵蓋沖壓工藝及模具設計 摘 要本次畢業(yè)設計是對上防塵蓋沖孔模具設計的要求，分別對模具的工作零部件等六大類零部件作詳細設計。設計的主要內容包括沖裁件的工藝分析及工藝方案的確定、工藝計算、沖裁模具的設計、模具的安裝與調整等。在工藝計算部分要對沖壓力的計算、模具壓力中心的確定、凸凹模尺寸并確定制造公差的計算、彈性元件的選取與計算等內容詳細計算。必要時還要對模具的主要零件進行強度驗算。在沖裁模的設計部分要對工作零件、定位零件、卸料與頂件零件、導向零件連接與固定零件等結構進行詳細的分析設計。要在設計過程中了解模具的工作過程和注意標準的選用，對單工序沖裁模的結構有進一步的了解。模具的安裝與調試部分要注意有導柱模具與無導柱模具的安裝方法及順序，通過模具的安裝，了解模具的組成及各部分零部件的作用等。注意模具安裝過后的試沖過程中常見的缺陷與解決方法等。通過這次畢業(yè)設計要對單工序模具有更近一步的了解，注意它與復合模和級進模之間的區(qū)別，三者雖然都是一副模具，但本次單工序模是單存的沖孔，在設計時要注意模具結構簡單、模具使用方便、模具壽命高等問題。并且要提高生產(chǎn)效率，保證產(chǎn)品的質量。關鍵詞：復合模 級進模 試沖 間隙配合 過渡配合 On dust cap ramming craft and mold design AbstractThis graduation project is the request which designs to on dust cap punch holes mold,Separately and so on six big kind of spare parts makes the detailed design to the mold work spare part. Design primary coverage including blanking craft analysis and craft plan determination, process design, blanking mold design, mold installment and adjustment and so on.n the process design part must to the ramming strength computation, the mold center of pressure determination, the convex-concave mold size and determines the manufacture common difference content detailed computations and so on computation, elastic part selection and computation。 When necessity also must carry on the intensity checking calculation to the mold major parts.In the punching die design part must to the work components, the localization components, the ex-denning and goes against components, the guidance components connection and fixed components isostructuralism carries on the detailed analysis design.。Must understand the mold in the design process the work process and attention standard selection,Has the further understanding to the single working procedure punching die structure.The mold installment and the debugging part must pay attention have the guide pillar mold to install the method and the order with the non-guide pillar mold,Through mold installment，Understands the mold the composition and various part of spare part function and so on. The attention mold installment from now on will try to flush in the process the common flaw and the solution and so on。Must have a nearer step understanding through this graduation project to the single working procedure mold,Pays attention to it enters between the mold with the superposable die and the level the difference，Three although all is a mold,But this single working procedure mold is Shan Cun the punch holes，When design must pay attention to the mold structure simply, the mold easy to operate, the mold life higher question. And must enhance the production efficiency,Guarantees the product the quality.Key word:Superposable die The level enters the mold Tries to flush Gap coordination Transition fit
