| Abstract: | Based on the controlling principle of arc roof mould structure springback,the bending springback contolling is studied on laser tailor-welded blank which is flangeless U-shaped part.The effects of compensation angle,roof force,punch radius and the clearance between dies are investigated,the comparison with common blank is also given.Then,orthogonal experimentation is introduced to optimize each parameter that influences the springback of laser tailor-welded blank.The result shows that the arc roof mould structure can effectively control the springback of laser tailor-welded blanks. |
