3、压生产就难以进行；没有先进的冲模，先进的冲压工艺就无法实现。冲压工艺与模具、冲压设备和冲压材料构成冲压加工的三要素，只有它们相互结合才能得出冲压件。1、设计说明书设计要求:设计该零件的冲裁模 冲压件图如下图所示:冲压技术要求:1. 材料:H622. 材料厚度:4mm3. 生产批量:中批量4. 未注公差:按IT14级确定.2 .零件的工艺性分析.2.1 零件的工艺性分析 该零件材料为H62(黄铜)结构简单,形状对称,凹模宽度B=121.2t(t为材料厚度) ,冲孔时有尺寸为6.5 5.2冲孔时,因受凸模强度的限制,孔的尺寸不应太小.冲孔的最小尺寸取决于材料性能,凸模的强度和模具结构等.根据表3-
4、3可查得圆形孔最小值得d=0.9t=0.9X4=3.6mm(1.52)t所以由冲件图可知C1=12-5.2/2-6.5/2=6.151X4=4, C2=88.9-21-29.4-31.5-2-2.5=2.51X4=4,C=18/2-6=3682.74,所以压力得以校核;(2).滑块行程 滑块行程应保证坯料能顺利地放入模具和冲压能顺利地从模具中取出.这里只是材料的厚度t=4,导料板的厚度H=12及凸模冲入凹模的最大深度14,即S1=4+12+14=30S=130,所以得以校核.(3).行和次数 行程次数为45/min.因为生产批量为中批量,又是手工送料,不能太快,因此是得以校核.(4)工作台面的
5、尺寸 根据下模座LXB=370X270,且每边留出60100,即L1XB1=470X370,而压力机的工作台面L2XB2=800X540,冲压件和废料从下模漏出, 漏料尺寸95X50,而压力机的孔尺寸为360X23,故符合要求,得以校核;(5) 滑块模柄孔尺寸 滑块上模柄孔的直径为60,模柄孔深度为80,而所选的模柄夹持部分直径为60,长度为70故符合要求,得以校核;(6).闭合高度 由压力机型号知Hmax=380 M=90 H1=100Hmin=HmaxM=380-90=290(M为闭合高度调节量/mm,H1为垫板厚度/mm)由式(1-24):( HmaxH1)-5H( HminH1)+10
6、,得(380100)-5262(290100)+10即 275262200 ,所以所选压力机合适,即压力机得以校核.6.冲压模具零件加工工艺的编制6.1凹模加工工艺过程 （如表6-1所示）表6-1 凹模加工工艺过程工序号工序名称工序内容设备1备料将毛坯锻成135mm110mm30mm2热处理退火3铣铣六面,厚度留单边磨量0.20.3mm铣床4平磨磨厚度到上限尺寸,磨侧基面保证互相垂直平面磨床5钳工划各型孔,螺孔,销孔位置划漏孔轮廓线6钳工加工好凸模,配作冲孔凹模达要求7铣铣漏料孔达要求铣床8钳工钻铰610,钻攻4XM12钻床9热处理淬火,回火,保证HRC606210平磨磨厚度及基面达到要求平面
