利用Autoforge软件研究不同加热位置对钢圆柱体试样的差温无模锻造过程的影响规律。通过实验和模拟结果的对比,证实采用Autoforge软件来模拟差温无模锻造过程是正确可行的。结果表明,要获得最佳的差温无模锻造效果,即变形仅发生在局部加热区,试样的最大压下量存在一个最大值,该最大值与局部加热位置相关。

The effect of different heating location on thermal differential mouldless forging of steel cylindrical billet is studied by use of Autoforge software. The feasibility of simulation of Autoforge software is validated by excellent agreement between experimental and simulating results. The research results indicate that in order to obtain ideal thermal differential mouldless forging effect there exists a maximal height reduction which is related to local heating location, even though the distortion only occurs in the local heating zone.
