For the springback problem of forming parts due to the disappearance of elastic deformation after stamping of clamp die, the forming process of clamp die was simulated by software ABAQUS, and the influence of the distribution of different friction characteristics on the surface of clamp die on the springback of forming part was studied. Firstly, the surface of clamp die was divided according to the characteristic structure of clamp die, and the springback amount of clamp forming part was used as the optimization target. Then, through the combination of single factor and uniform design, the distribution of optimal friction characteristics on the surface of clamp die was determined as μ5=0.12，μ6=0.13，μ7=0.14，μ9=0.16，μ10=0.18，μf=0.11，and the friction coefficient of other regions is 0.12. At this time, the springback amount of clamp forming part is the smallest. Based on the numerical simulation, the experimental verification was conducted. And the experiment results show that the springback of clamp forming part is improved.
