XX學(xué)院 畢業(yè)設(shè)計(jì)論文
摘要
隨著中國工業(yè)不斷地發(fā)展,模具行業(yè)也顯得越來越重要。本次畢業(yè)設(shè)計(jì)的任務(wù)是蓋冒墊片沖壓工藝分析和模具的具體結(jié)構(gòu)設(shè)計(jì)。通過查閱了相關(guān)文獻(xiàn)資料,對接觸片零件進(jìn)行工藝性分析,選擇并確定符合于給定條件的最優(yōu)工藝方案,及進(jìn)行了工藝與設(shè)計(jì)的有關(guān)計(jì)算,如:選擇基本工序,確定其順序、工序數(shù)目及工序組合形式。介紹了主要零部件的設(shè)計(jì)理念,詳細(xì)剖析了設(shè)計(jì)過程中一些思路,以及某些非標(biāo)準(zhǔn)零件的使用特點(diǎn)。闡述了復(fù)合模的設(shè)計(jì)要點(diǎn), 使產(chǎn)品質(zhì)量達(dá)到設(shè)計(jì)要求。然后以此為基礎(chǔ),設(shè)計(jì)出沖壓模具主要零件的結(jié)構(gòu)。并在設(shè)計(jì)中,介紹了零件的排樣圖、定位設(shè)計(jì)、沖裁力的計(jì)算和壓力中心的計(jì)算。

With the continuous development of Chinese industry, the mold industry has become increasingly important. The graduation project's mission is to take cover gasket stamping process analysis and design of the specific structure of the mold. By consulting the relevant literature, parts of the contact plate process analysis, selection and determine the conditions found at the given optimum solution, and carried out the calculation and design process, such as: choice of basic processes, determine their order, the number of processes and process combinations. Introduced the main components of the design concept, detailed analysis of the design process, some ideas, and some non-standard parts to use features. Describes the design features of the composite model, so the product quality to meet the design requirements. Then this basis, design the structure of the major parts stamping die. And in the design, the layout of parts described map, locate the design, calculation and blanking force center of pressure calculations..
Keywords: Take cover gasket Mold Design Compound Die Stamping process
