利用普通冲裁方式可达到图样要求 由于该 件外形简单 形状规则 适于冲裁加工 材料为 Q235 钢板 2 确定工艺方案零件属于大批生产 工艺性较好 但不宜采用复合模 因为最窄处 A 的 距离为 6 5mm 图 1 而复合模的凸凹模最小壁厚需要 8 5mm 见表 2 27 所以不能采 用复合模 如果采用落料以后再冲孔 则效率太低 而且质量不易保证 由于该件批量较 大 因此确定零件的工艺方案为冲孔 切断级进模较好 并考虑凹模刃口强度 其中间还 需留一空步 排样如图 2 所示 F Z7 L9 K 8 k l Q o Y g U i3 s h In 2016 County Economic workshop Shang of speech comrade are this county economic workshop of main task is full implement
