摘　　要：运用Deform-3D有限元软件对轴承外圈闭式模锻成形进行了数值模拟,研究了连皮位置和型式对闭式模锻过程中金属流动、充填、凸模受力、应力应变和温度的影响。为了减少缺"肉"量和降低凸模受力,给出了合理的连皮位置和型式。这能为轴承外圈和类似锻件的闭式模锻工艺及模具设计提供依据。The bearing outer ring closed-die forging process was simulated by using Deform-3D software. The effects of wad location and type on metal flow, filling, force of punch, stress, strain and temperature were studied. In order to reduce metal deficiency of forging and the force of punch,the reasonable wad location and type were given. This can provide a basis for closed-die forging process and the die design of bearing outer ring and similar forgings.
