采用有限元数值模拟技术与生产试制结合的方法,研究了同步环环坯尺寸对于同步环飞边大小的影响。结果表明,环坯内径对锻件内飞边影响较大,而环坯高度对锻件外飞边影响较大。根据研究结果,提出了四种用于提高该铜质同步环材料利用率的环坯设计方案,有限元数值模拟发现环坯外径67.0 mm、内径49.0 mm、高度12.3 mm时,内飞边尺寸明显减小,且锻件成形良好。生产实践验证了该环坯设计方案的可行性,优化环坯尺寸后材料利用率从59.29%提高到69.04%。
The influence of the ring blank size of the synchronous ring on the flash edge size of the synchronous ring was studied by combining the finite element numerical simulation technology with the production prototype. The results show that the inner diameter of the ring blank has a significant influence on the flash within the forging, while the height of the ring blank affects the outer flash of the forging. According to the research results, four design schemes of the ring blanks for improving the utilization rate of the copper ring are put forward. Finite element simulation results show that when the ring blanks have an outer diameter of 67.0 mm, an inner diameter of 49.0 mm and a height of 12.3 mm, Significantly reduced, and forging a good shape. The production practice verified the feasibility of the design of the billet. After optimizing the billet size, the utilization rate of the billet increased from 59.29% to 69.04%.
