冲裁凹模刃口热装镶拼结构的工艺研究

Technology of Thermal Loading Mosaic Structure for Blanking Die Edge

冲裁模具应用于批量大的冲压件生产时,刃口常使用较贵重的合金材料制造,而凹模占模具生产成本的比例高,寿命短,冲裁凹模刃口采用热装过盈配合的镶拼结构,能够延长寿命约一倍,并减少贵重合金材料的用量而降低制造成本。

Blanking die used in large batch of stamping parts proaucuon, its Diaae otten oe maoe oy pre- cious metal materials. Concave die possess high proportion of the cost of mold production, And its lifetime is short, The blanking can be prolong, And paper also introduces cess. die used on the hot charging cooperate this way reduce the amount of precious together with insert structure, which lifetime metal material and manufacturing cost, This the operation method and practical technological parameters of the hot charging pro-
