针对某差速器盖热锻模，基于修正的Archard磨损模型，应用有限元模拟软件Deform分析了坯料和模具预热温度以及成型速度对终锻模磨损的影响规律。研究结果表明，在试验数据范围内，随着坯料预热温度的升高模具磨损量呈减小趋势，当坯料预热温度超过1230℃时，这种趋势放缓；提高模具预热温度，模具磨损量逐步增大，当预热温度超过200℃时这种趋势更加明显；成型速度小于400 mm/s时，模具磨损量随成型速度的提高而减小，当成型速度超过400 mm/s时，模具磨损量随成型速度的提高会先增大后减小。

The influencing rules of billet, die preheating temperature and forming speed on the wear of a finish-forging die for a differential mechanism cover was analyzed based on the modified Archard wear model and the finite element simulation software DEFORM. Within the scope of the experimental data, the research shows that: with the increase of billet preheating temperature, the wear is reduced gradually. When the billet preheating tem-perature is larger than 1 230℃, the trend is less obvious. Raising die preheating tempera-ture, the wear increases gradually. When the preheating temperature is over 200 ℃, the trend is more obvious. The wear value of die decreases with the increase of speed when the forming speed is less than 400 mm/s. But when the forming speed is more than 400 mm/s, the wear value of die increases first and then decreases with the increase of the forming speed.
