摘要
采用U形拉伸-弯曲成形试验方法研究了用于先进高强度双相钢裸板DP780的3种模具材料的磨损性能.结果表明：经过热扩散碳化物覆层（TD）处理的模具材料V4E及DC53的耐磨损性最佳;经过真空热处理的模具材料DC53的耐磨性能较差;对于经TD处理的V4E及DC53,模具的磨损主要集中在凹模圆角入口0°~15°区域,而对于真空热处理的DC53,模具在凹模圆角和法兰处均出现了严重的磨损.
Finding the most suitable tool material is the main way to reduce the wear on the surface of parts and enhance the life of tools in the advanced high strength steel stamping. This paper investigated the wear resistance and characteristics of different tool materials--V4E（TD）, DC53 （TD） and DC53 （vacuum heat treatment） in U-stretching-bending experiment using DP780. The result shows that the V4E（TD） and DC53（TD） have a good performance on wear resistance, while the DC53 by vacuum heat treatment does not perform well. For the first two inserts, wear mainly occurs in the area of 0°- 15°on the die radius. While on the DC53 （vacuum heat treatment）, serious wear occurs on both the die radius and flange.
