雙耳止動墊片的沖孔落料沖裁模具設(shè)計【級進模】
摘 要
隨著社會生產(chǎn)力的提高與發(fā)展，現(xiàn)如今模具制造中的沖壓加工已經(jīng)是一種非常成熟的金屬加工方法。它具有操作簡單、精度高、產(chǎn)品一致性好、生產(chǎn)效率高、材料利用率高和用于大批量生產(chǎn)等特點。本次畢業(yè)設(shè)計根據(jù)已經(jīng)確定的沖載件即雙耳止動墊片的尺寸進行沖載工藝的分析及設(shè)計，從而得到?jīng)_載工藝。根據(jù)已經(jīng)確定好的沖載工藝進行凸凹模結(jié)構(gòu)參數(shù)的計算與設(shè)計，并根據(jù)文獻資料最終確定級進模的凸凹模結(jié)構(gòu)。根據(jù)設(shè)計好的凸凹模結(jié)構(gòu)選擇標準零件和模架，從而完成模具的設(shè)計并校核。完成模具設(shè)計后，用UG軟件完成模具的三維模型并采用AutoCAD軟件完成模具裝配圖的制圖。本次畢業(yè)設(shè)計還獨立完成與專業(yè)相關(guān)且不少于4萬字符的指定英文資料翻譯。通過本次畢業(yè)設(shè)計，我系統(tǒng)的學(xué)習(xí)和掌握了模具設(shè)計的知識和制造加工工藝的編制技術(shù)。我采用了較好的設(shè)計思想和設(shè)計方法，成功的完成了雙耳止動墊片沖孔落料級進模的畢業(yè)設(shè)計。
關(guān)鍵詞：設(shè)計；工藝分析；沖壓模具；結(jié)構(gòu)計算；級進模。
Abstract
With the improvement and development of social productive forces, the stamping of Mold Manufacturing now is already a very advanced metal processing methods. It has the feature of simple operation, high accuracy, product consistency, high production efficiency, high utilization of materials and for mass production and so on. The graduation project bases on the pieces（binaural washer）of punch set that have been identified in binaural washer dimensions for analysis and design of the craft of punch set resulting in getting the craft of punch. I will do the job of calculation and design of structural parameters punch basing on the craft of punch set that has been determined，and ultimately determine the progressive of punch structure of Progressive Die according to the literature. I select the standard parts and the mold according to the designed structure of punch structure .Thus completing the mold design. After the completion of mold design, I use UG software to complete three-dimensional model and use AutoCAD software to complete the graphics of mold assembly drawing. The graduation project is independently complete not less than40,000 characters of the specified English translation associated with professional. Through this graduation design, I learn systematically and mastered the preparation of technical of manufacturing process and knowledge of mold design. I used the advanced design concepts and design methods, and I successfully complete the graduate design of Binaural Washer Punching and Blanking Progressive Die Design.
Key words : design; process analysis; stamping die; progressive die; structural calculations.
