Abstract：

For the problem of a large warping deformation and great surface springback in the bottom plate guide of relay protection box processing, by analyzing the characteristics of two kinds of processing technologyrolling and stamping processes, the stress of bottom plate guide was simulated and analyzed by the software Ansys. Then, the deformation of bottom plate guide was simulated, and the corresponding die was designed according to the bottom plate size. Meanwhile, the stamping die and stamping process were improved. Finally, the machine tool was selected for experiments and it verified that the simulation results were basically the same as the actual production. The results show that the deformation of rolling is about 20 mm, which affects the screw fastening and plugin installing. However, the deformation of stamping process is 2 mm and meets assembly requirements. Thus, the stamping process method solves the problem of large deformation in precision chassis processing.
