摘要
分析了汽车冲压模具使用的工况条件,讨论了冲压模具的主要失效形式和汽车冲压件的主要缺陷,同时介绍了超音速火焰喷涂的原理、特点及应用优势。通过对超音速火焰喷涂技术在模具上的应用和效果分析得出,采用超音速火焰喷涂技术,可有效地提高模具的使用性能,消除冲压件表面的拉毛缺陷,从而延长模具的使用寿命。
The work conditions of the automobile stamping die were analyzed, and the main failure mode of stamping dies and the main defect of automobile stampings were discussed. Meantime, the principal, features as well as application advantages of high-velocity oxygen fuel were introduced. According to the actual application and effect of high-velocity oxygen fuel on automobile dies, the using capabilities of the die were enhanced and the galling defect was removed by high-velocity oxygen fuel, so as to increase using time of die greatly.
