| Abstract: | In this paper,the basic bend form of shaftkind parts and the theory of reversebending straightening based on elastic-plastic mechanics theory have been researched.A method of precise straightening based on the stroke as controlled object was adopted.The straightening experiments have been done on the YH40-10 type automatic hydraulic precise straightening press machine,which was developed independently.The theoretical results are compared with the experimental results and the non-linear Finite Element Method(FEM) results generated by ANSYS.It proved that the method is feasible and effective. |
