摘　　要：针对U形梁冲压成形后尺寸不稳定且模具使用寿命短的问题,利用Autoform对U形梁成形过程及模具的受力分析进行判断,通过合理控制模具零件间隙、回弹补偿、翻边镶件高度与材料流动圆角,保证了成形制件质量,同时延长了超强厚板成形模的使用寿命。In order to solve the problems that the dimension of stamping formed U-shaped beam was unstable and the service life of die was short,the forming process of U-shaped beam and the force analysis of the die were judged by Autoform.By reasonably controlling the clearance of die parts,springback compensation,the height of flanging insert,and the material flow fillet,the quali⁃ty of forming parts could be guaranteed,and the service life of forming die for super-strength thick plate could be extended.
