使用精密连续模,通过多工步冲制,可获得形成复杂的精度冲件。在制造精密连续模各工步主要零件时,由于存在加工误差或测量误差,使主要零件的尺寸在一定范围中波动。定位孔的正确选位不仅可保证模具在多工步工作中冲件尺寸符合图纸要求,且凸模与凹的间隙比较均匀。这样能提高模具的使用寿命,並使冲件截面整齐光滑。因此,定位孔的选位就不应该简单地根据横具图纸的理想尺寸来决定,而应该仔细地实测凹模各部份形状尺寸,再根想具体情况选择最佳选位方案。
The use of precision continuous mode, through the multi-step Chong Chong system, access to the formation of complex precision punch. In the manufacture of precision continuous mode of the main steps of the various steps, due to the existence of machining errors or measurement errors, so that the size of the main parts in a certain range of fluctuations. Positioning the correct location of the hole can not only ensure that the mold in the multi-step work Chong size in line with the drawings, and the gap between the punch and concave more evenly. This will increase the service life of the die and make the cross-section of the punch neat and smooth. Therefore, the positioning hole positioning should not simply based on the ideal size of the horizontal drawing to determine, but should carefully measure the shape and size of the various parts of the die, and then select the best case according to the specific situation options.
