Note that when designing the bending of hole,and need to consider the to the size, materials, mass production of the product , the first part is to analysis the process of the part . so the program of blanking process and die structure has been confirmed. As a results, the workpiece need single operation dies to acplish , just like drawing die and bending mould are used to produce the parts. Then based on the process design calculations, the stock layout design can be ensured. It is needed to carry on the blanking force and the center of pressure putation, according to which the press can be choosed. Calculating the punch and die cutting edge size and tolerances, then design and selection the parts of die. During the structural design, it is mainly about the design of the punch, die, punch and die, positioning parts, unloading and ejecting devices, mold, pressing equipment, fasteners, and so on. Press need to be checked, then draw the drawings and assembly drawings of parts, finally the design has been pleted. Key words： Ushaped par, punching die, bending die， single operation dies, rebound III 目 錄 1 緒論 ................................................................. 1 模 具的分類 .......................................................... 1 設(shè)計目的意義 ........................................................ 2 2 零件結(jié)構(gòu)工藝分析 ..................................................... 3 毛坯材料的分析 ...................................................... 3 工藝分析 ............................................................ 3 工藝方案的確定 ...................................................... 3 3 工藝計算 ............................................................. 5 毛坯尺寸計算 ........................................................ 5 工作部分尺寸計算 .................................................... 6 4 成型設(shè)備的選擇 ........................................................ 8 壓力機的選擇 ........................................................ 8 5 模具結(jié)構(gòu)的選定 ....................................................... 10 模具類型的選擇 ..................................................... 10 定位方式的選擇 ..................................................... 12 卸料、出件方式的選擇 ............................................... 13 壓邊裝置的確定 ..................................................... 13 導向方式的選擇 ..................................................... 13 壓力中心的確定 ..................................................... 13 6 模具零件設(shè)計與校核 ................................................... 15 工作零件的結(jié)構(gòu)設(shè)計 ................................................. 15 凸、凹模的校核 ..................................................... 16 沖壓設(shè)備的校核 ..................................................... 16 其他零部件的設(shè)計選用 ............................................... 17 主要工作零件加工工藝 ............................................... 19 7 模具的裝配過程 ....................................................... 20 模具的基本安裝 ..................................................... 20 模具的裝配與調(diào)整 .................
