Abstract：

The large bar formed by free forging can easily produce various bending deformation. For the problems existing in manual straightening, such as low straightening efficiency, poor straightening result and straightening stroke relying on empirical method, a kind of fully automatic vertical bar straightening machine was proposed firstly, which could obtain the profile by scanning the bar automatically, determine the straightening position, calculate processing parameters and implement the straighten process according to the measured data. In addition, a math model calculating straightening stroke and initial bending amount was obtained based on the ideal elasticplastic material model. Finally, the straightening process was simulated by finite element（FE）software ANSYS. The results show that the straightening stroke obtained by this model can be used as the basis for automatic straightening calculation of bar.
