摘要：

以高强钢幅板为研究对象，采用DEFORM软件对初始工艺方案下的冲压成形效果进行模拟，通过分析得到影响凹模磨损的关键工艺参数。然后，以坯料预热温度、冲压速度、模具预热温度、模具硬度为因素，以凹模磨损峰值为响应量，通过设计响应面试验，对因素和响应量之间的关系进行拟合，得出响应面模型并对模型的准确性进行了验证。得出最优参数组合为：坯料预热温度为800 ℃、冲压速度为6.1 mm·s-1、模具预热温度为201.5 ℃、模具硬度为59 HRC。采用最优参数组合进行实际试模，模具的寿命明显提高，验证了模拟响应面模型和模拟结果的准确性，为实际生产中分析模具磨损情况提供了理论依据。

For the high strength steel shield, the effect of stamping under the initial process scheme was simulated by software DEFORM, and the key process parameters that affect the wear of die were obtained by analysis. Then, taking the blank preheating temperature, stamping speed, die preheating temperature and die hardness as factors and taking the maximum wear of die as the response, the response surface test was designed to fit the relationship between the factors and the response to get the response surface model and verify the accuracy of the model. The results show that the optimal parameter combination is obtained with the blank preheating temperature of 800 ℃, the stamping speed of 6.1 mm·s-1, the die preheating temperature of 201.5 ℃, and the die hardness of 59 HRC. The actual test of the die is conducted by the optimal parameters. Thus, the service life of the die was significantly improved, which verifies the accuracy of the simulation response surface model and the simulation results to provide a theoretical basis for die wear situation in the actual production.
