  1、CHONGYASHEBEI

  冲压设备(如压力机)的精度与刚性对冲压模具寿命的影响极为重要。冲压设备的精度高、刚性好,冲压模具寿命大为提高。例如:复杂硅钢片冲模材料为 Crl2MoV,在普通开式压力机上使用,平均复磨寿命为1-3万次,而新式精密压力机上使用,冲压模具的复磨寿命可达6~12万次。尤其是小间隙或无间隙冲模、硬质合金冲压模具及精密冲压模具博悦彩票APP下载必须选择精度高、刚性好的压力机,否则,将会降低模具寿命,严重者还会损坏模具。

  2.MOJUSHEJI

  (1)模具的导向机构精度。准确和可靠的导向,对于减少模具工作零件的磨损,避免凸、凹模啃伤影响极大,尤其是无间隙和小间隙冲裁模、复合模和多工位级进模则更为有效。为提高模具寿命,必须根据工序性质和零件精度等要求,正确选择导向形式和确定导向机构的精度。一般情况下,导向机构的精度应高于凸、凹模配合梢度。

  (2)模具(凸、凹模)刃口几何参数。凸、凹模的形状、配合间隙和圆角半径不仅对冲压件博悦彩票APP下载成形有较大的影响,而且对于模具的磨损及寿命也影响很大。精度要求较高的,宜选较小的间隙值;反之则可适当加大间隙,以提高模具寿命。
