Blanking bending of progressive die design in real life is more mon mould. The design of the mould only cost is low, the efficiency of stamping out to finished product, but also can reduce cost, reduce leadtime. According to the analysis in the design of the parts can be obtained layout forms of material utilization, layout diagram. Cutting force calculation, pressure center and the size of the overall design, again. Final design process scheme. Keywords: lathe bed fixed thing。Blanking crooked。 Progressive die 3 I 目 錄 1 緒 論 .................................................................................................................................. 1 2 沖裁彎曲件的工藝分析 ...................................................................................................... 2 工藝方案 ....................................................................................................................... 2 導(dǎo)向方式的選擇 ........................................................................................................... 2 模具總結(jié)構(gòu)設(shè)計(jì)工藝分析 ........................................................................................... 3 模具類型的選擇 ................................................................................................. 3 定位方式的選擇 ................................................................................................. 3 工序組合方式的選擇 ................................................................................................... 3 3 沖壓模具工藝參數(shù)的設(shè)計(jì) .................................................................................................. 4 模具總體結(jié)構(gòu)設(shè)計(jì) ....................................................................................................... 4 模具類型的選擇 ................................................................................................. 4 定位方式的選擇 ................................................................................................. 4 卸料方式的選擇 ................................................................................................. 4 模具設(shè)計(jì)工藝計(jì)算 ....................................................................................................... 4 毛坯尺寸計(jì)算 ..................................................................................................... 4 搭邊值的確定 ..................................................................................................... 4 材料利用率的計(jì)算 ............................................................................................. 4 沖壓力的計(jì)算 ............................................................................................................... 5 落料力的計(jì)算 ..................................................................................................... 5 沖孔力的計(jì)算 ..................
