冲裁间隙标准.doc

冲裁间隙标准1、对于金属材料，我们取5%-10%，非金属材料取2%-4%2、普通冲裁:取板材厚的510%3、跟要求的质量有关，高质量有时为0，一般取0.05t,我喜欢取小值，复杂模具可稍大4、如果是比较厚的还是大点的好，如35毫米的我们取15205、一般0.2mm的铜皮放0.01mm6、T*0.077、我们都是10%12%8、根据断面要求,按片厚不同,520%双面间隙不等9、2毫米以内，一般取5-10%，根据材料抗剪性取大小值，2毫米以外，间隙则要随料厚增加而加大取值，另外，和工艺要求，孔型都有关系，当要求光洁冲裁时，可以取极小的间隙10、T0.3时,取3-5%T为佳11、一般根据材料厚度取料厚的510，我们公司一般在线切割时进行补偿，不用在凸凹模标注公差。12、我们选用7%10%，单面冲裁（剪切）或立切系数减半，最小间隙视加工能力和设备、模具导向精度，我们是0.07。对中、厚板料和硬料取上限间隙。13、（4%-8%）*T14、当然我们应当注意材料的硬度及零件的冲裁毛刺要求15、材料厚度小用0.050.07XT;中用0.070.09XT;大用0.090.12XT16、一般铜材取4%-5%的料厚17、我以前是做集成电路切筋模的,材料:铜厚度:0.126单边间隙:0.03518、日本JIS标准规定的冲裁间隙值表1材質別抜（板厚対）材質精密抜一般抜軟鋼25610硬鋼48915素鋼46712鋼36712銅1347黄銅14510青銅25610洋白25610（軟）1348（硬）25610245819、和材质料厚都有关，我们用得多的为5%7，2.0以上的料，间隙会大一些，一般取%10，对AL材和马口铁会小一些，大约%2-%4之间。20、我们如果线割时才用快走丝割就取料厚的5%10%，如果线割时才用慢走丝割就取料厚的2.5%。21、材料都是0.035-0.05厚度，所以呢通常取材料厚度的2%22、是根据材料类型，二是根据零件精度及断面要求。机电行业冲裁模初始双面间隙材料厚度T8、45A2、A3、D4108F、10、15、H62L2、L3、L4、L5D44、QSnP10-1T1、T2、T3Z最小Z最大Z最小Z最大Z最小Z最大Z最小Z最大0.350.030.050.020.050.010.030.50.040.080.030.070.020.040.020.030.80.090.120.060.100.040.070.0250.0451.00.110.150.080.120.050.080.040.061.20.140.180.100.140.070.100.050.071.50.190.230.130.170.080.120.060.102.00.280.320.200.240.130.180.080.122.50.370.430.250.310.160.220.110.173.00.480.540.330.390.210.270.140.203.50.580.650.420.490.250.330.180.264.00.680.760.550.600.320.400.210.294.50.790.880.640.720.380.460.260.345.00.901.00.750.850.450.550.300.406.01.161.260.971.070.600.700.400.508.01.751.871.461.580.850.970.600.7210.02.442.562.042.161.141.260.800.92电器仪表行业冲裁模初始双面间隙材料厚度软铝紫铜、黄铜、软钢杜拉铝、中等硬钢硬钢（C0.080.2)（C0.30.4)Z最小Z最大Z最小Z最大Z最小Z最大Z最小Z最大0.20.0080.0120.0100.0140.0120.0160.0140.0180.30.0120.0180.0150.0210.0180.0240.0210.0240.40.0160.0240.0200.0280.0240.0320.0280.0360.50.020.030.0250.0350.030.040.0350.0450.60.0240.0360.0300.0420.0360.0480.0420.0540.80.0320.0480.040.0560.050.0640.050.071.00.040.060.050.070.060.080.070.091.20.060.080.070.100.080.110.100.121.50.080.110.090.120.110.140.120.152.00.100.140.120.160.140.180.160.202.50.150.200.180.230.200.250.230.283.00.180.240.210.270.240.300.270.334.00.280.360.320.400.360.440.400.485.00.350.450.400.500.450.550.500.606.00.480.600.540.660.600.720.660.788.00.720.880.800.960.881.040.961.1210.00.91.11.01.21.11.31.21.4汽车、拖拉机行业冲裁模初始双面间隙材料厚度0.8、10、3516Mn40、5065Mn09Mn、A3、B3Z最小Z最大Z最小Z最大Z最小Z最大Z最小Z最大0.50.040.060.040.060.040.060.040.060.80.070.100.070.100.070.100.060.091.00.100.140.100.140.100.140.090.131.20.130.180.130.180.130.181.50.140.240.170.240.170.232.00.250.360.260.380.260.382.50.360.500.380.540.380.543.00.460.640.480.660.480.663.50.540.740.580.780.580.784.00.640.880.680.920.680.924.50.721.000.680.960.781.046.01.081.440.841.201.141.508.01.201.68耐热不锈钢冲裁模初始双面间隙材料厚度Z最小Z适宜Z
