【正文】 dern industrial processing method, is widely used in automotive, energy, machinery, household electrical appliances, aerospace, defense industry and daily life of the production. This design is the design of the temperature control switch, household and stamping die mold diagram of the product, industrial analysis and mold design, the cold stamping mould related knowledge as the basis, elaborated the cold stamping mould design process. This design for pound die is designed, specified workpiece between to make use of Auto CAD and other software design drawing. Considering the efficiency of products, parts of the stamping manufacturability as well as the plexity and accuracy, and many other factors, cold stamping process analysis and calculation, puts forward reasonable process scheme and anization form, introduced die design of the layout and feeding and discharging and guide way, also analyzes the mold of the main ponents (such as intensive, discharging device, drawing punch, fixed plate, plate, etc.) design and manufacturing. Determine the stamping forming process and the specific parts of detailed calculation and checking, ensure the working reliability of the mold, and various fittings with accuracy. Lists the mould needs a detailed list of spare parts, and draw the mold assembly drawing and part drawing. Key words: Cold stamping Process analysis Household temperature control switch Composite mould Punching deep drawing III 目錄 第一章 前言 ............................................................... 1 我國(guó)模具的背景與現(xiàn)狀 ............................................... 1 我國(guó)模具未來(lái)發(fā)展的趨勢(shì) ............................................. 1 研究意義 ........................................................... 1 第二章 分析零件的工藝性和確定工藝方案 ..................................... 3 家用溫控開關(guān)的設(shè)計(jì) ................................................. 3 沖壓件的工藝分析 ................................................... 3 沖裁件斷面質(zhì)量 ..................................................... 4 冷沖壓工藝方案的確定 ............................................... 4 模具結(jié)構(gòu)形式的確定 ................................................. 5 排樣方案的確定 ..................................................... 6 搭邊方案的確定 ..................................................... 6 材料的利用率 ....................................................... 7 第三章 模具結(jié)構(gòu)形式的選用 ................................................. 8 模具類型的選擇 ..................................................... 8 定位方式的確定 ..................................................... 8 導(dǎo)料板的選擇 ....................................................... 8 擋料銷的選擇 ...................................................... 9 壓料裝置 .......................................................... 10 卸料板的選 擇 ...................................................... 10 出件方式 .......................................................... 10 送料方式的確定 .................................................... 10 導(dǎo)向方式的選擇 .................................................... 10 第四章 模具主要工藝參數(shù)的計(jì)算 ............................................ 12 沖裁工藝的設(shè)計(jì)分析 ................................................ 12 間隙對(duì)沖裁工作的影響 .............................................. 12 沖裁力計(jì)算 ........................................................ 13 沖孔力的計(jì)算： .................................................... 13 卸料力及推件力計(jì)算 ................................................ 13 拉深力的計(jì)算 ...................................................... 14 壓邊力的計(jì)算 ...................................................... 15 拉深功的計(jì)算 ...................................................... 15 初選壓力機(jī) ........................................................ 15 模具壓力中心的確定 ............................................... 16 IV 第五章 拉深工藝的分析與確定 .............................................. 17 拉深加工的工藝性 .................................................. 17 計(jì)算拉深次數(shù) ...................................................... 18 第六章 模具工作部分尺寸計(jì)算 .............................................. 20 沖裁模刃口尺寸計(jì)算 ................................................ 20 落料凸凹模刃口的計(jì)算 .............................................. 21 沖孔刃口尺寸計(jì)算 .................................................. 24 孔中心尺寸的計(jì)算 .................................................. 25 拉深凸、凹模的計(jì)算 ................................................ 25 第七章 模具的結(jié)構(gòu)設(shè)計(jì) .................................................... 27 模架的選用 ........................................................ 27 模具閉合高度 ...................................................... 27 落料凹模 .......................................................... 27 拉深凸模 .......................................................... 29 凸凹模的設(shè)計(jì) ...................................................... 31 彈性卸料板 ........................................................ 33 第八章 模具的總體安裝 .................................................... 36 模具的裝配 ........................................................ 36 模具零件 .......................................................... 37 確定沖壓設(shè)備 ...................................................... 38 模具的裝配 ........................................................ 38 重要零件的制造加工工藝 ............................................ 39 主要參考文獻(xiàn) ............................................................. 42 致謝 ..................................................................... 43 1 第一章 前言 我國(guó)模具的背景與現(xiàn)狀 模具廣泛應(yīng)用到工業(yè)、農(nóng)業(yè)等行業(yè)中，在飛機(jī)、家用電器、日用五金等制造業(yè)中有著極為重要的地位。確定沖壓成型工藝過(guò)程并對(duì)個(gè)具體部分進(jìn)行詳細(xì)的計(jì)算和校核，確保模具工作的可靠性，各配件配合的準(zhǔn)確性。 本設(shè)計(jì)對(duì)指定工件進(jìn)行的復(fù)合模設(shè)計(jì)，利用 Auto CAD等軟件對(duì)之間進(jìn)行設(shè)計(jì)繪圖。 畢 業(yè) 論 文 論文題目 家用溫控開關(guān)冷沖壓模具 設(shè)計(jì)與制造 系 別 電子信息工程系 專 業(yè) 機(jī)械設(shè)計(jì)制造及其自動(dòng)化 班 級(jí) 09 機(jī)械 3 班 學(xué) 號(hào) 學(xué)生姓名 指導(dǎo)教師（簽名） 完
