【正文】 制造周期由于模具結(jié)構(gòu)及制造精度要求與產(chǎn)品形狀及生產(chǎn)批量有關(guān)，因此沖模種類繁多。（3）有利于實(shí)現(xiàn)模具的計(jì)算機(jī)輔助設(shè)計(jì)與制造模具技術(shù)標(biāo)準(zhǔn)是實(shí)現(xiàn)模具計(jì)算機(jī)輔助設(shè)計(jì)與輔助制造的基礎(chǔ)，可以說沒有模具標(biāo)準(zhǔn)化就不可能建立起模具計(jì)算機(jī)輔助設(shè)計(jì)與制造系統(tǒng)。大型沖壓模具已能生產(chǎn)單套重量達(dá)50多噸的模具。轎車覆蓋件模具，具有設(shè)計(jì)和制造難度大，質(zhì)量和精度要求高的特點(diǎn)，可代表覆蓋件模具的水平。但總體上和國外多工位級(jí)進(jìn)模相比，在制造精度、使用壽命、模具結(jié)構(gòu)和功能上，仍存在一定差距。NC、DNC技術(shù)的應(yīng)用越來越成熟，可以進(jìn)行傾角加工超精加工。模具表面強(qiáng)化技術(shù)也得到廣泛應(yīng)用。PTC公司提出的單一數(shù)據(jù)庫、參數(shù)化、基于特征、全相關(guān)的概念改變了機(jī)械CAD/CAE/CAM的傳統(tǒng)觀念，這種全新的概念已成為當(dāng)今世界機(jī)械CAD/CAE/CAM領(lǐng)域的新標(biāo)準(zhǔn)。新版本旨在增強(qiáng)功能和卓越質(zhì)量，蘊(yùn)含了豐富的最佳實(shí)踐，可以幫助用戶更快、更輕松地完成工作，大幅度地提高個(gè)人和流程效率 Pro/E三維設(shè)計(jì)軟件特點(diǎn)Pro/Engineer系統(tǒng)主要功能如下:(1)真正的全相關(guān)性，任何地方的修改都會(huì)自動(dòng)反映到所有相關(guān)地方。Pro/Engineer系統(tǒng)用戶界面簡潔，概念清晰，符合工程人員的設(shè)計(jì)思想與習(xí)慣。如果利用CAD、CAM單元技術(shù)制造模具，制造精度低、周期長，為了解決上述難題，我們將并行工程技術(shù)引入到模具制造過程中。在初步確立產(chǎn)品的三維模型后，設(shè)計(jì)、制造及輔助分析部門的多位工程師同時(shí)進(jìn)行模具結(jié)構(gòu)設(shè)計(jì)、工程詳圖設(shè)計(jì)、模具性能輔助分析及數(shù)控機(jī)床加工指令的編程，而且每一個(gè)工程師對(duì)產(chǎn)品所做的修改可自動(dòng)反映到其他工程師那里，大大縮短設(shè)計(jì)、數(shù)控編程的時(shí)間。摘 要本文是將L型板件作為設(shè)計(jì)模型，將冷沖壓模具的相關(guān)知識(shí)作為依據(jù)，闡述冷沖壓模具的設(shè)計(jì)過程。并在繪制模具的裝配圖和零件圖的過程中熟悉了繪圖軟件的操作。 in addition, according to calculate the punch pressure, discharge power and push the pieces force, we select the stamping equipment。 Pro/E中國地質(zhì)大學(xué)畢業(yè)設(shè)計(jì)（論文）開題報(bào)告學(xué)生姓名學(xué)號(hào)05208711專業(yè)班級(jí)指導(dǎo)教師職稱講師單 位河北農(nóng)業(yè)大學(xué)課題性質(zhì)設(shè)計(jì)□ 論文□課題來源科研□ 教學(xué)□ 生產(chǎn)□ 其它□畢業(yè)設(shè)計(jì)（論文）題目基于Pro/E的模具建模及仿真1. 目的及意義沖壓模具，是在冷沖壓加工中，將材料（金屬或非金屬）加工成零件（或半成品）的一種特殊工藝裝備，稱為冷沖壓模具（俗稱冷沖模）。如汽車，飛機(jī)，拖拉機(jī)，電器，電機(jī)，儀表，鐵道，郵電，化工以及輕工日用產(chǎn)品中均占有相當(dāng)大的比重。4）操作簡便，特別適宜于大批量生產(chǎn)和自動(dòng)化。（３）拉深模 是把板料毛坯制成開口空心件，或使空心件進(jìn)一步改變形狀和尺寸的模具。（２）復(fù)合模 只有一個(gè)工位，在壓力機(jī)的一次行程中，在同一工位上同時(shí)完成兩道或兩道以上沖壓工序的模具。利用Pro/E確定的壓力中心要比傳統(tǒng)的計(jì)算方法簡單很多并且更加準(zhǔn)確，另外Pro/E的運(yùn)動(dòng)仿真功能，工程圖、爆炸圖、裝配圖及產(chǎn)品號(hào)和零件表的自動(dòng)生成功能及Pro/E的干涉檢測功能，這都會(huì)有效地降低設(shè)計(jì)錯(cuò)誤，從而降低沖壓模具的成本。總結(jié)幾年來應(yīng)用Pro/E的實(shí)踐經(jīng)驗(yàn)，Pro/E應(yīng)用在模具設(shè)計(jì)中不僅能夠提高設(shè)計(jì)質(zhì)量而且能夠大大縮短設(shè)計(jì)周期。，仿真。畢業(yè)設(shè)計(jì)（論文）主要參考資料：[1] [M].北京：.[2] 郝利劍,張洪波,[M].北京:.[3] 孫江紅,[M].北京:中國鐵道出版社,2004.[4] [M].煤礦機(jī)械,2007.[5] 伍先明,[M].國防工業(yè),2011.[6] 夏巨甚,[M].江西科學(xué)技術(shù)出版社,2003.[7] [J],2009.[8] [M].畢業(yè)設(shè)計(jì)（論文）應(yīng)完成的主要工作：。畢業(yè)設(shè)計(jì)（論文）進(jìn)度安排：序號(hào)畢業(yè)設(shè)計(jì)（論文）各階段內(nèi)容時(shí)間安排備注1調(diào)查研究，查找文獻(xiàn)和資料. 2翻譯外文資料、撰寫開題報(bào)告2012. . 3撰寫文獻(xiàn)綜述4學(xué)習(xí)軟件、撰寫論文5論文答辯課題信息：課題性質(zhì)： 設(shè)計(jì)√ 論文□ ?課題來源： 教學(xué)□ 科研□ 生產(chǎn)□ 其它√發(fā)出任務(wù)書日期： 20111205 指導(dǎo)教師簽名： 2011 年 12 月 05 日教研室意見：教研室主任簽名：年 月 日 學(xué)生簽名：外文原文Abstract：Die designing is a demanding and hard work．To design a separate die for each product is time consuming and expensive task．This paper presents an idea of sets of standard reference dies．it gives a concept of flexible die designing using a reference standard die designed in a popular mercial CAD／CAM software—Pro／Engineer．Rather than designing a separate die for each part，just update the die design by selecting the die dimensions as required．The use of this concept will prove to reduce time and cost of product in manufacturing industry． Key words：die；flexible die designing system ；standardization；Pro/E；secondary developmentAt present, the industrial developed countries and regions in the mold industry has been gradually standardize and serialization. In China, although the majority die within the enterprises have business standards, but generally not high degree of standardization, standardization of stamping die in the dielimited parts of the parts. To achieve real savings stamping die design time and shorten the processing cycle, cost savings, reduce design and manufacturing staff workload purposes, it needs to develop a flexible stamping die design system. At the same time, stamping die serialization of the scope of standardization and can not be confined to diepart of the fixed panels, boards, the top plate unloading device monly used ponents such as stamping or even die structure, we should achieve serialization and standardization.As CAD / CAM technology in the design and manufacture die in the course of extensive application, it should first be standardized stamping die from the CAD system began. Some largescale mercialization of the CAD / CAM software, such as Pro / E, UG, and so on. Have developed a specialized injection mold design package. And stamping die design for the special software, users need to be developed.l The application tools Pro / E in stamping die design flexibility in the system development Pro / Engineer by the United States has developed a set of PTC CAD / cAM / CAE software. Pro / E using a single database And featurebased, the design parameters of the model, provides users with 1 The development is very convenient for stamping die flexible system of tools juice Family Table Fanaily Fable known as the Family Table, the structure used to create the same or similar parts of the size and characteristics of the standardized database tables, is devoted to the establishment of a standard parts library tool. The use of the former first family table to create a generic representation of the ponents (the generic), according to the need to target and then added to the family table a series of management.Family sheet management can be the object of a size (dimension), features (feature), parameters (parameter) and assembly parts (ponent), and so on.A family table can have multiple levels, that is a generic parts can contain multiple subponents (instance, also known as examples), and each Instance can contain their own Sub Instance. Discharge screw (stripperbolt) the family table structure as shown in Figure 1.Figure 1 Family Table hierarchy RelationsRelations (relations) between mathematics and procedures, including grammar, and its main role is to be part or assembly of the relevance of the data by size symbols, and other parameters of grammar (syntax) to establish mathematical formula to meet the design requirements. Pro / E system of relations can be found in Sketch, Feature, Part and in the Assembly. Simple sentence, judgement and sentence is to establish relations of mon format. Simple sentence that a simple mathematical relationship between the size of direct response associated situation. The use of simple format, such as d6 = L. BP 1 2 * d3.
