机械工业中,冲压零件占的比例较大,这就需解决冲压模具问题。一九八二年初,黑龙江省和哈尔滨市的科技部门举办了多次学习班,大力推广使用锌基合金模具。一、锌缺合金应用于哪些模具锌基合金应用于冲裁模的阴模和模体及弯曲模、成型模、拉深模的阴、阳模等。用于冲裁模可冲4～6毫米厚的铜板;如果 Mechanical industry, stamping parts accounted for a larger proportion, which need to solve the problem of stamping die. In early 1982, the science and technology departments of Heilongjiang Province and Harbin held several workshops to promote the use of zinc-based alloy molds. First, the zinc-alloy used in what die Zinc-based alloy die blanking die and die body and bending die, forming die, drawing die Yin, Yang and so on. For blanking die can punch 4 ~ 6 mm thick copper;
