鏈 輪的沖壓工藝及模具設(shè)計(jì)
摘 要
本次畢業(yè)設(shè)計(jì)是對(duì)鏈輪的沖壓工藝及模具設(shè)計(jì)的要求，分別對(duì)模具的工作零部件等六大類零部件作詳細(xì)設(shè)計(jì)。設(shè)計(jì)的主要內(nèi)容包括沖裁件的工藝分析及工藝方案的確定、工藝計(jì)算、沖裁模具的設(shè)計(jì)、模具的安裝與調(diào)整等。
在工藝計(jì)算部分要對(duì)沖壓力的計(jì)算、模具壓力中心的確定、凸凹模尺寸并確定制造公差的計(jì)算、彈性元件的選取與計(jì)算等內(nèi)容詳細(xì)計(jì)算。必要時(shí)還要對(duì)模具的主要零件進(jìn)行強(qiáng)度驗(yàn)算。
在沖裁模的設(shè)計(jì)部分要對(duì)工作零件、定位零件、卸料與頂件零件、導(dǎo)向零件連接與固定零件等結(jié)構(gòu)進(jìn)行詳細(xì)的分析設(shè)計(jì)。要在設(shè)計(jì)過程中了解模具的工作過程和注意標(biāo)準(zhǔn)的選用。
模具的安裝與調(diào)試部分要注意有導(dǎo)柱模具與無導(dǎo)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(shè)計(jì)要對(duì)模具有更近一步的了解，注意復(fù)合模與級(jí)進(jìn)模之間的區(qū)別，兩者雖然都是一副模具，在設(shè)計(jì)時(shí)要注意模具結(jié)構(gòu)、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(zhì)量。

The Design of the Drawing Dies for Chain Wheel
Abstract
This graduation project is the request which designs to the drawing dies for chain wheel, 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-denting and goes against components, the guidance components connection and fixed components is structuralism 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 the drawing dies for chain wheel, Pays attention to the superposable die with the level the difference, Two although all is a mold，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 words: Superposable die The level enters the mold Tries to flush Gap coordination Transition fit
