摘　　要：结合某不同规格铜材连续挤压生产线,对连续挤压过程中影响模具寿命的因素如工作温度和挤压轮的转速及生产数据进行了分析,得出了模具寿命的回归方程及最佳工作条件,其中挤压轮的转速对模具寿命的影响最大.Based on an extrusion production line for copper strips of different sizes,an analysis was conducted on production data and some factors affecting the die service life such as working temperature and the wheel rotating velocity during the continous extrusion process. A regression equation of the die service life as well as the optimum working condition were obtained,for which the wheel rotating velocity affected the die service life the most.
