A 3D 为热戒指滚动的僵硬塑料、联合的 thermo 机械的 FE 模型(HRR ) 被开发基于使 3D 软件,转的然后联合的热,材料流动和温度变形在 HRR 的戒指的分发被模仿,他们上的进程参数的效果被分析。结果证明戒指的变丑不一致随司机转动和磨擦因素或闲散转动的 feed 率和戒指空白的起始的温度的减少的旋转速度的增加挡住增加。有闲散转动的 feed 率的增加的戒指空白减少或戒指空白和磨擦因素的起始的温度的减少的温度不一致。有最佳戒指空白的温度分发是最一致的司机在下面转动的旋转速度。获得的结果能为形成参数优化和质量控制提供一个指南。
A 3D rigid-plastic and coupled thermo-mechanical FE model for hot ring rolling(HRR) was developed based on DEFORM 3D software, then coupled heat transferring, material flow and temperature distribution of the ring in HRR were simulated and the effects of process parameters on them were analyzed. The results show that the deformation nonuniformity of ring blank increases with the increase of the rotational speed of driver roll and friction factor or the decrease of the feed rate of idle roll and initial temperature of ring blank. The temperature nonuniformity of ring blank decreases with the increase of the feed rate of idle roll or the decrease of initial temperature of ring blank and friction factor. There is an optimum rotational speed of driver roll under which the temperature distribution of ring blank is the most uniform. The results obtained can provide a guide for forming parameters optimization and quality control.
