摘要：

针对继电保护箱体底板导轨加工过程中容易发生较大的翘曲变形、加工面回弹较大的问题，通过分析两种加工工艺——辊压与冲压工艺的特点，利用Ansys软件对底板导轨受力进行仿真分析，模拟底板导轨的受力变形状况，并依据底板尺寸设计出相应的模具，同时对冲压模具与冲压工艺进行改进，最后选取机床进行试验对比，验证了模拟结果与生产实际基本一致。结果表明：辊压成形变形最大约为20 mm，变形较大，对螺钉紧固、插件安装有较大影响；冲压工艺变形为2 mm，装配后基本满足要求。该冲压工艺方法解决了精密机箱加工变形较大的问题。

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.
