【正文】 摘 要 隨著科學(xué)技術(shù)的發(fā)展，對壓鑄件產(chǎn)品的安全性和造型美觀的要求不斷提高。根據(jù)使用的不同，對零件的質(zhì)量評價(jià)有所不同。如何生產(chǎn)出高質(zhì)量的零件，對節(jié)約材料、能源和提高經(jīng)濟(jì)效益都有很大的意義。分析了燈罩這種形狀復(fù)雜、壁薄零件的結(jié)構(gòu)特點(diǎn)。針對壓鑄中易形成裂紋、拉伸不足等缺陷的工藝特性，在根據(jù)理論分析的要求和數(shù)據(jù)的基礎(chǔ)上運(yùn)用Sol idworks軟件進(jìn)行三維實(shí)體造型，并對未知的尺寸進(jìn)行規(guī)定。然后利用這個(gè)三維實(shí)體計(jì)算零件的質(zhì)量，在Solidworks軟件中根據(jù)零件的質(zhì)量來設(shè)計(jì)出的預(yù)定厚度的圓形坯料板材直徑。根據(jù)所得的直徑來確定原始坯料的一些尺寸，為后續(xù)的設(shè)計(jì)和研究提供一定的依據(jù)。同時(shí)利用Solidworks軟件或其它三維軟件對沖壓模型可行性進(jìn)行分析和設(shè)計(jì)，利用軟件進(jìn)行燈罩成型模的相關(guān)模具設(shè)計(jì)。通過運(yùn)用Solidworks軟件，同時(shí)結(jié)合逆向造型的方法來設(shè)計(jì)相對應(yīng)的模具，為了實(shí)現(xiàn)零件的成型，本人利用Solidworks軟件設(shè)計(jì)四副模具，分別設(shè)計(jì)落料模、液壓模、翻邊模和卷邊模，使原材坯料經(jīng)過以上四副模具的加工來得到所要求的零件。研究成果是得到四副模具三維模型和相對應(yīng)的二維CAD圖尺寸圖。結(jié)論是得到所設(shè)計(jì)的零件的四副模具的相關(guān)數(shù)據(jù)，如果在實(shí)際生產(chǎn)中，可能運(yùn)用的話，再添加其它相關(guān)的數(shù)據(jù)，可以成批生產(chǎn)。最后，對本次的模具設(shè)計(jì)進(jìn)行總結(jié)。關(guān)鍵詞：落料； 液壓； 翻邊； 卷邊Abstract With the development of science and technology, Diecasting products for safety and aesthetic shapes rising. According to different use, Evaluation of the quality of parts are different. How to produce highquality parts, to save materials, energy and increase economic efficiency has great significance. Analysis of the plexity of the shade of such a shape, thinwalled parts of the structural characteristics. Easy for diecasting in the formation of cracks, lack of defects in the tensile properties of the process, and in accordance with the requirements of theoretical analysis and data based on the use of Solidworks 3D solid modeling software, and the provisions of unknown size. Then calculated using the threedimensional entities, the quality of parts, in accordance with Solidworks software to design parts of the quality of the target plate thickness the diameter of the circular blank. According to the original blank diameter to determine the number of dimensions for the design and followup to provide a basis for research. At the same time, the use of Solidworks software or other threedimensional software model of the stamping feasibility analysis and design, use of software related to shade Mold mold design. Through the use of Solidworks software, bined with the method of reverse modeling of the corresponding mold design, molding parts in order to achieve, I use Solidworks Mold Design four molds, respectively, blanking die design, hydraulic mold, flanging and crimping die mold, so that the original material for more than four blank mold after processing to get the required parts.Research results are threedimensional models of four molds and the corresponding size chart diagram of twodimensional CAD. Conclusion is designed by four mold parts of the relevant data, if in the actual production may be used, then add other relevant data, can be massproduced. Finally, the die design of this summary.Keywords: Blanking。 Hydraulic。 flanging。 Crimping目 錄摘 要Abstract第一章 緒論 ..................................................................................................................1 課題研究的目的和意義 .............................................................................................1 鋁擠壓材工業(yè)的發(fā)展現(xiàn)狀 ........................................................................................1 該行業(yè)的其它相關(guān)零件的研究 ................................................................................2 薄壁深錐零件的拉伸成形方面的研究 .....................................................2 鋁鍋冷擠壓工藝及模具等類似產(chǎn)品的設(shè)計(jì) .............................................2 本論文研究的基本內(nèi)容及擬解決的主要問題 .....................................................3第二章 總體方案的設(shè)計(jì) ..............................................................................................4 設(shè)計(jì)要求 .......................................................................................................................4 設(shè)計(jì)分析和流程 ..........................................................................................................5 對模具結(jié)構(gòu)和機(jī)構(gòu)工作原理的解說 .......................................................................7 對沖裁落料模工作過程和原理的解釋說明 .............................................7 對液壓模工作過程和原理的解釋說明 .....................................................8 對翻邊模工作過程和原理的解釋說明 .....................................................8 對卷邊模工作過程和原理的解釋說明 .....................................................8第三章 落料模 的設(shè)計(jì) ..................................................................................................9 工藝分析計(jì)算 ..............................................................................................................9 工件的排樣方案 .........................................................................................9 工藝力計(jì)算和壓力機(jī)選擇 .......................................................................11 對模具工作部分尺寸計(jì)算 .......................................................................12 模具零部件的設(shè)計(jì)計(jì)算 ...........................................................................................13 凹模的設(shè)計(jì)計(jì)算 ........................................................................................13 選擇標(biāo)準(zhǔn)模架 ...........................................................................................14 凹模和下模座的關(guān)聯(lián)設(shè)計(jì) .......................................................................14第四章 液壓模的設(shè)計(jì) ................................................................................................24 設(shè)計(jì)拉深件時(shí)應(yīng)遵循的原則 ..................................................................................24 設(shè)計(jì)拉深件時(shí)，對拉深件厚度不均勻現(xiàn)象的考慮 ...........................................25 確定拉深件的尺寸精度 ...........................................................................................26 利用 SOLIDWORKS對于其它相關(guān)尺寸的確定 .........................................................27 液壓拉深成形 ............................................................................................................28 用 SOLIDWORKS設(shè)計(jì)液壓成型模 ...............................................................................29 工藝分析計(jì)算并選擇模具結(jié)構(gòu)形式 .......................................................30 模具零部件的設(shè)計(jì)計(jì)算 ...........................................................................32 裝配圖模型 ................................................................................................................34第五章 翻邊模的設(shè)計(jì)
