洛陽理工學(xué)院畢業(yè)設(shè)計(jì)(論文)彎架板沖壓工藝及模具設(shè)計(jì)摘 要隨著現(xiàn)代制造技術(shù)的迅速發(fā)展,在工業(yè)生產(chǎn)中模具已成為生產(chǎn)各種產(chǎn)品不可缺少的重要工藝裝備。特別是在沖壓產(chǎn)品的生產(chǎn)過程中,沖壓模具的應(yīng)用極其廣泛。本文主要進(jìn)行彎架板的沖壓模具設(shè)計(jì)。該沖壓模具的特點(diǎn)是具有對(duì)稱機(jī)構(gòu)。在設(shè)計(jì)過程中分析了彎架沖壓件的工藝特點(diǎn),介紹了彎架板的沖壓模結(jié)構(gòu)及模具的整體設(shè)計(jì)過程,并分析和闡述了模具凸凹模零件及各標(biāo)準(zhǔn)件的選材及選用原則和方法、彎架板的結(jié)構(gòu)要素、零件的尺寸公差和精度的選擇、以及壓力機(jī)的選擇和校核。此彎架板沖壓模具設(shè)計(jì)的結(jié)構(gòu)特點(diǎn)是多工序的單工序模。其主要工作零件為彎曲凸凹模和沖孔凸凹模,為了保證保證合模動(dòng)作準(zhǔn)確可靠,還設(shè)置了限位擋塊和壓緊塊。本套沖壓模具包括落料、彎曲、沖孔三套模具。工作原理:合模時(shí),上模座利用導(dǎo)柱導(dǎo)套的作用下,帶動(dòng)凸模向下運(yùn)動(dòng),利用壓力機(jī)的壓力,使材料分離或彎曲。從而獲得所需零件,最后需要切斷工藝。該模具結(jié)構(gòu)設(shè)計(jì)操作方便,使用壽命長,零件質(zhì)量達(dá)到技術(shù)要求。生產(chǎn)效率高。關(guān)鍵詞:彎架板,落料模,彎曲模,沖孔模。 Curved frame plate bending stamping process and die designABSTRACTWith the rapid development of modern manufacturing technology, industrial production molds in the production of various products have bee indispensable technical equipment. Especially in the production process of stamping, stamping die for a very wide range. In this paper, for pipe support of stamping die design. The stamping die is characterized by a symmetrical body. In the design process of the pipeline characteristic stamping process, introduced the pipe support structure and mode of stamping die of the overall design process and analysis and elaboration of the mold punch and die ponents and the Standard Material Selection and use principles and methods Pipe supports for the structure of elements, parts tolerance and accuracy options, and press select and check. The pipe support structure stamping die design process is characterized by a single multiprocess mode. The main working parts to bend and punch punch punch, in order to ensure the clamping action to ensure the accuracy and reliability, but also set a limit block and the pression block. This set of stamping dies including blanking, bending, punching three sets of mold. Blanking die works: mold, the mold base on the use of lead column in the role set, the drive punch downward motion, the press pressure, and the material separation. To obtain the necessary parts. Bending mold works: mold, the mold base on the use of lead column in the role set, the drive punch downward motion, the press of pressure on bending. To obtain the necessary parts Punching mold works: mold, the mold base on the use of lead column in the role set, the drive punch downward motion, the press pressure, and the material separation. To obtain the necessary parts Finally need to cut off the process. The mold structure design and convenient operation, long life, part quality and meet the technical requirements. High efficiency.KEY WORDS: Curved frame plate, blanking die, bending die, punch.3目 錄前 言 1第1章 工件的沖壓工藝分析 2 2 模具總體結(jié)構(gòu)設(shè)計(jì) 3 模具類型的選擇 3 定位方式的選擇 3 卸料方式的選擇 3 導(dǎo)向方式的選擇 3第2章 模具設(shè)計(jì)的工藝計(jì)算 4 4 條料寬度的確定 6 導(dǎo)板間間距的確定 7 排樣 7 8第3章 彎曲模具的設(shè)計(jì)與計(jì)算 10 彎曲力的計(jì)算 10 彎曲部分刃口尺寸的計(jì)算 11 最小相對(duì)彎曲半徑 11 12 模具結(jié)構(gòu)形式的選擇計(jì)算 15 壓力中心的計(jì)算 15 沖模閉合高度的計(jì)算 16 模座的選用 16第4章 沖孔模的設(shè)計(jì)與計(jì)算 19 計(jì)算沖裁力的公式 19 20 20 沖裁模間隙的確定 204. 3 沖孔部分刃口尺寸計(jì)算 22 模具壓力中心與計(jì)算 23 模具結(jié)構(gòu)類型及形式的選擇與設(shè)計(jì) 25 壓力中心的計(jì)算 25 沖模閉合高度的計(jì)算 25 模座的選用 25結(jié) 論 27謝 辭 28參考文獻(xiàn) 29前 言隨著經(jīng)濟(jì)的發(fā)展,沖壓技術(shù)應(yīng)用應(yīng)用范圍越來越廣泛,在國民經(jīng)濟(jì)各部門中,幾乎都有沖壓加工生產(chǎn),它不僅與整個(gè)機(jī)械行業(yè)密切相關(guān),而且與人們的生活緊密相連。沖壓工藝與沖壓設(shè)備正在不斷地發(fā)展,特別是精密沖壓。高速?zèng)_壓、多工位自動(dòng)沖壓以及液壓成形、超塑性沖壓等各種沖壓工藝的迅速發(fā)展,把沖壓的技術(shù)水平提高到了一個(gè)新高度。新型模具材料的采用和鋼結(jié)合金、硬質(zhì)合金模具的推廣,模具各種表面處理技術(shù)的發(fā)展,沖壓設(shè)備和模具結(jié)構(gòu)的改善及
