在仪表制造行业中,常有厚度为0.01～0.3mm的冲制件。这些零件的特点是材料薄而软,不允许有毛刺。我厂过去对薄片零件的冲裁,通常采用一般的钢制冲模。由于材料薄,就要求凹凸模间隙很小,甚至于接近无间隙,因而模具制造精度就要求高,同时对冲床的平行与垂直度也有较高的要求。即使制造出这样高精度的模具,使用寿命也不 In the instrument manufacturing industry, often the thickness of 0.01 ~ 0.3mm red parts. These parts are characterized by thin and soft materials, does not allow burrs. I plant in the past on the blanking sheet parts, usually using ordinary steel die. Due to the thin material, it is required to punch and die gap is small, or even close to the gap, which requires high precision molds, while the punch of the parallelism and verticality also have higher requirements. Even if such a high-precision molds are manufactured, the service life is not
