摘　　要：提出了某航天产品用多弧段封头产品的淬火处理方法;通过有限元分析,得出了多弧段封头在底部约束情况下的热处理畸变趋势;建立了多弧段封头淬火装置的三维模型,介绍了多弧段封头淬火装置的基本结构。通过有限元分析得出在淬火装置约束下,多弧段封头热处理,总畸变量为16.0 mm,Z向15.0 mm,X向8.5 mm。通过对多弧段封头淬火装置的热畸变情况分析,提出了淬火装置的优化设计方案,优化后的多弧段封头的热处理,总畸变量为7.0 mm,Z向10.0 mm,X向3.0 mm。解决了多弧段封头热处理畸变过大问题,并通过生产验证。Quenching treatment method for a multi-arc head parts used in aerospace products was developed.Through the finite element analysis,the thermal tend for the multi-arc head under the constraint of the bottom was studied.The 3 D model of the multi-arc head quenching fixture was established,and the basic structure of the multi-arc head quenching fixture was introduced.The results of thermal distortion distribution for the multi-arc head under the constraint of quenching fixture are obtained by the finite element analysis(FEM).The FEM results show that the total distortion of multi-arc head is 16.0 mm,in Z direction is 15.0 mm,and in X direction is 8.5 mm.Through the analysis of the local thermal distortion of the multi-arc head quenching fixture,the optimal design scheme of the quenching fixture is proposed.The thermal distortion distribution of the multi-arc head is optimized.The total distortion is 7.0 mm,in Z direction is10.0 mm,and in X direction is 3.0 mm.The problem for large distortion of the multi-arc head heat treatment is solved and verified by production.
