摘要
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。
The wear of hot forging die crotch for turnbuckle fork is serious. When about 2000 forgings were produced using the die, the forgings＇ size was out of tolerance and replacing dies affected productivity. Through the analysis of the metal flow law of the forging, the reason of the wear of the die was summarized based on Archard model of wear. Process optimization method of changing forging square as preforming blank was carried out. The original and optimal scheme were simulated. The results show that during every single piece production after optimization, the maximum wear depth of the die reduces 0.26 μm, the material utilization rate increases to 80.4%, and each piece of energy-saving is 18.6 MJ. The die life is increased to more than 3600 pieces in the actual production.
