Abstract：

In view of the deformity of low surface quality of transformer radiator tube during practical punching,such as wrinkle and so on,the paper analyzes the practical punching technological process, finds the reason of deformity and suggests an effective method to solve it.The research on numerical simulation for the bending form process of transformer radiator tube has been done with advanced FEM software which is named as Dynaform and dynamic explicit solution method.The form limit diagram and the distributing diagram of thickness thinning are the result of two different section simulation.The bending form of curve-transition-smooth-section transformer radiator tube,which is difficult to be wrinkled has better surface quality by the contrast analysis of two different simulated results.The suggested method is proved effective in improving the surface quality of the bending form of transformer radiator tube.
