Drawing technology and die design of automobile torsion beam part

JIANG Ying-fang1,MENG Ying1,ZHU Yuan-you2(1.School of Mechanical Engineering,Jiangsu University,Zhenjiang 212013,China;2.Department of Mechanical Engineering,Nanjing Institute of Technology,Nanjing 210013,China)  
Punching process was made through analyzing the structural characteristics and technology of torsion beam which was one of auto panels.Considering the forming problems of crack,wrinkle and spring back,drawing process including the drawing direction,shape of binder surface,draw bead and so on,and the structure of drawing die were analyzed.The produced torsion beam and the die show that the punching processes and the die structure are reasonable and feasible.Three-dimensional part modeling and die designing are performed in UG conveniently and quickly.It can show the part relation of the die more actually and reduce the defects of die designing in practice.
