建立精冲模具磨损有限元分析模型，采用有限元软件Deform?3D 对常温下的精冲凸模磨损进行仿真分析，研究模具材料的硬度、毛坯与模具间摩擦因数和成型载荷等工艺参数对模具磨损的影响。结果表明：凸模边缘的磨损严重，而侧面的磨损量较小；最大磨损深度随着模具材料硬度的增大而减小，随着摩擦因数的增大而增大；反顶力也是影响对凸模磨损的重要因素，最大磨损深度随着反顶力的增大而增大。
建立精遲模具磨損有限元分析模型，採用有限元軟件Deform?3D 對常溫下的精遲凸模磨損進行倣真分析，研究模具材料的硬度、毛坯與模具間摩抆因數和成型載荷等工藝參數對模具磨損的影響。結果錶明：凸模邊緣的磨損嚴重，而側麵的磨損量較小；最大磨損深度隨著模具材料硬度的增大而減小，隨著摩抆因數的增大而增大；反頂力也是影響對凸模磨損的重要因素，最大磨損深度隨著反頂力的增大而增大。

Fine blanking die wear model for finite element analysis was built.Simulation was carried out in normal tem?perature for analyzing fine blanking punch wear by using the finite element software Deform?3D.The influences on the die wear by process parameters,such as die material hardness,coefficient of friction between blank and die,and the forming load were analyzed.The results show that the punch edge wear is serious,but the amount of wear in the convex side is small.The maximum wear depth is decreased with the increase of the hardness of die material,and increased with the in?crease of friction coefficient.The counterforce is also the important factor influencing the punch wear,the maximum wear depth is increased with the increase of the counterforce.
