影响精冲模具使用寿命有诸多因素,但主要受零件的加工难度、材料厚度、材料内部的含碳量及光亮冲切面占整个冲切面的百分比等因素的影响。 以下介绍精冲模具使用寿命的经验计算方法。 例如由表1: 零件加工难度S_2,系数F_1=6 材料厚度3mm,系数F_2=100 There are many factors influencing the service life of fine blanking die, but it is mainly affected by the processing difficulty of the part, the thickness of the material, the carbon content inside the material and the percentage of the bright blanking surface which accounts for the entire blanking area. The following describes the experience of fine blanking die life calculation method. For example, from Table 1: part processing difficulty S_2, coefficient F_1 = 6 material thickness 3mm, coefficient F_2 = 100
