I 法蘭盤沖壓工藝與模具設(shè)計 摘 要 模具是工業(yè)產(chǎn)品生產(chǎn)使用的重要工業(yè)裝備 它以其自身的特殊形狀通過一些方 式使原材料成型 現(xiàn)代工業(yè)生產(chǎn)中 由于模具的加工效率高 互換性好 節(jié)省原材料 模具技術(shù)已成為衡量一個國家制造水平的重要標志之一 模具技術(shù)能促進工業(yè)產(chǎn) 品的發(fā)展和質(zhì)量的提高 并能獲得極大的經(jīng)濟效益 模具是效益放大器 用模具生產(chǎn) 的產(chǎn)品的價值往往是模具價值的幾十倍 上百倍 本設(shè)計運用沖壓成型工藝及模具設(shè)計的基礎(chǔ)知識 首先分析了工件的成形工藝及 模具成形結(jié)構(gòu)對制件質(zhì)量的影響 介紹了沖壓模具設(shè)計時要注意的要點 通過對制件 進行工藝分析 可確定制件的成形加工用一套復合模即可 從控制制件尺寸精度出發(fā) 對沖壓模具的各主要尺寸進行了理論計算 以確定各工作零件的尺寸 從模具設(shè)計到 零部件的加工工藝以及裝配工藝等進行詳細的闡述 并應用 CAD 進行各重要零件的設(shè) 計 關(guān)鍵詞 落料 沖孔 翻邊 Flange plate stamping technology And die design II Abstract Mold which is used to would raw material due to its special shape is a piece of important equipment in the process of producing industrial products It is wildly used in modern industry because of its effective machining exchangeable quality saving raw materials and lower costs One important way of measuring manufacture level of country is the technology of mold which can advance the quality of products and promote its development and agin great economical benefits mold is effective amplifier Products with the value of the mold is often ten times and a hundred times the value of the mold This design the elementary knowledge which designs using the stamping formation craft and the die first has analyzed the work piece formed craft and the die forming structure to the workpiece quality influence Introduced the shell cover filling piece stamping die design when must pay attention to the main point through carries on the craft analysis to the workpiece may determine the workpiece the formed processing uses set of superposable dies Embarks from the control workpiece size precision counter shell cover filling piece stamping die each main dimension has carried on the theoretical calculation by determined each work components the size designs from the die to the spare part processing craft as well as the assembly craft and so on carries on the detailed elaboration and carries on each important components using CAD the design Keywords blanking punching flanging 目 錄 1 緒論 1 2 工藝分析 3 3 工藝方案的確定 4 III 4 主要設(shè)計尺寸的計算 5 4 1 翻邊高度校核 5 4 2 排樣與材料利用率計算 6 4 2 1 毛坯尺寸計算 6 4 2 2 排樣搭邊的設(shè)計 6 4 2 3 搭邊值的確定 6 4 3 工藝力的計算 7 4 4 復合模工作零件刃口尺寸計算 8 4 5 翻邊模凸凹模間隙大小及凹模的工作尺寸計算 9 4 6 壓力中心的確定與設(shè)備預選 10 5 設(shè)計選用模具零 部件 11 5 1 復合模結(jié)構(gòu)設(shè)計 11 5 1 1 復合模結(jié)構(gòu)的選取 11 5 1 2 凹模的選取 11 5 1 3 固定板的選取 12 5 1 4 彈性卸料板的選取 13 5 1 5 凸凹模設(shè)計 14 5 1 6 沖孔凸模 15 5 1 7 墊板 16 5 1 8 模柄的選取 16 5 1 9 上 下模座的選取 16 5 1 10 彈性元件橡膠的選取 17 5 1 12 頂件塊 17 5 1 13 支撐板 18 5 1 14 卸料螺釘 18 5 1 15 擋料銷 導料銷 19 IV 5 1 16 推料機構(gòu)構(gòu)的設(shè)計 19 5 1 17 模架的選用 19 5 1 18 壓力機的選擇 20 5 1 19 公稱壓力校核 20 5 1 20 工作臺面的校核 21 5 1 21 行程次數(shù)校核 21 5 1 22 滑塊行程校核 21 5 1 23 模具總裝圖 22 5 2 翻邊模具設(shè)計 23 5 2 1 模具結(jié)構(gòu)原理 23 5 2 2 凸 凹模的設(shè)計 23 5 2 3 模架 24 5 2 4 定位零件 24 5 2 5 卸料出件裝置 24 5 2 6 壓力機的選用與校核 25 5 2 7 模具設(shè)計輔助程序 25 5 2 8 模具總裝圖 26 6 設(shè)計總結(jié) 27 致謝 28 參考文獻 29
