花兰叉热锻模具内裆部位磨损严重。当持续使用模具生产2000件左右时,锻件尺寸超差,更换模具影响生产。基于Archard磨损模型,通过分析锻件的金属流动规律,总结了模具磨损过快的原因。进行了改锻方为制坯的工艺优化方法,并对原始和优化方案进行模拟分析。结果显示,优化工艺后,每单件生产模具最大磨损深度降低了0.26μm,同时材料利用率提高到80.4%,每件节能18.6 MJ。实际生产中模具寿命提高到3600件以上。 Hualien fork hot forging die crotch wear. When the continuous use of mold production of about 2000, forgings over size, replace the mold affect the production. Based on Archard wear model, by analyzing the metal flow rule of forgings, the reason of excessive wear of die was summarized. The process optimization of the preform for billets was carried out, and the original and optimized schemes were simulated. The results show that the maximum wear depth per die per die is reduced by 0.26 μm and the material utilization rate is increased to 80.4% after optimizing the process, saving an energy of 18.6 MJ per piece. The actual production of mold life increased to 3600 or more.
