摘要：

为解决薄壁回转体零件采用传统分体式拼焊和刚性胀瓣胀形方式制造时出现的产品尺寸精度差、装配困难、合格率低和成本高等问题，以内高压胀形技术为基础，设计立式内高压胀形方案，运用有限元分析软件进行模拟、理论计算辅助分析，并开展实际生产试验进行验证。结果表明：直径为Φ300~Φ800 mm的薄壁回转体零件的立式内高压胀形方案可行，立式内高压胀形方案最佳的密封结构为Y型密封结构，该密封结构需保证预制坯外径大于Y型密封圈内径Φ0.3~Φ0.5 mm，且预制坯外径圆度小于0.2 mm，最大可密封160 MPa液室压力。研究结果为大直径薄壁回转体零件的整体精密成形提供了新思路。

In order to solve the problems of poor product dimensional accuracy, difficult assembly, low pass rate and high cost when thin-walled rotating parts were manufactured by traditional split welding and rigid expansion and bulging method, the vertical internal high-pressure bulging scheme was designed based on internal high-pressure pulging technology, and finite element analysis software was used for simulation, theoretical calculations and auxiliary analysis. Furthermore, the actual production tests were conducted for verification. The results show that the vertical internal high-pressure bulging scheme for thin-walled rotating parts with a diameter of Φ300-Φ800 mm is feasible. Its optimal sealing structure is Y-shaped sealing structure, which must ensure that the outer diameter of preformed blank is larger than the inner diameter of Y-shaped sealing ring by Φ0.3-Φ0.5 mm, and the outer diameter roundness of preformed blank is within 0.2 mm, and the maximum liquid chamber pressure that can be sealed is 160 MPa. Thus, the research result provides new ideas for the integral precision forming of large-diameter thin-walled rotating parts.
