沖壓工藝模具結(jié)構(gòu)設(shè)計(留存版)
【正文】 ult of the layout, the two parts on the centersymmetry, the module handles Design Center is the symmetry of the two die Centre. Block the adoption of side edge device, the step to ensure accuracy. Based on the outer edge of materials design size die, and then to die with a size of the actual practice of determining the outer edge of die size, according to Punch designed punch size, and then punching punch to determine the actual size of die Size , And other parts from the actual situation of selection criteria. Identify the parts and die after the calculation of the size necessary to press the Nominal pressure, and, accordingly choose Press. This set of mold can be efficiently produced in large quantities, the assembly of simple, reliable, high life.Key words：Supporting plate,Ramming craft,Superposable die目 錄1 序言 12 工藝分析 23 沖裁工藝方案的確定 3 方案種類 3 方案比較 3 方案的確定 34 模具結(jié)構(gòu)形式的確定 3 排樣設(shè)計與計算 4 排樣方法的確定 4 確定搭邊值 4 確定條料步距 4 條料利用率 5 排樣圖 5 沖裁壓力的計算 6 沖裁力的計算 6 卸料力 6 推件力 6 頂件力 7 壓力機公稱壓力的確定及機型選擇 7 單
