【摘要】 辊轧叶片加工成本低、效率高,更重要的是可使叶片的产品质量和使用功能进一步提高,使叶片材料潜在性能得到充分发挥。某型发动机高压压气机静子叶片型面极其复杂,H公司在实际的生产过程中暴露出工艺水平不适应、叶片质量状态不稳定等问题,影响产品质量和可靠性。本文系统分析了现有辊轧工艺存在的缺陷和不足,并针对性地展开了一系列研究试验工作。通过应用计算机模拟技术,研究毛料的平板制坯技术,设计出满足叶片型面辊轧精密成型要求的坯料;采用辊轧模具型面补偿设计技术,实现模具型腔的精密成型;利用计算机辅助分析及调整功能,改进辊轧机精度控制能力;完成高温合金材料轧制成型的技术特性分析;研究辊轧过程中,叶片的六自由度调整技术。通过以上研究及改进工作,轧制的压气机叶片几何尺寸、组织性能均满足设计图及相关技术条件要求。而且对辊轧过程的精密控制,压气机叶片的质量和稳定性大为提高。本研究与改进工作突破了复杂型面辊轧叶片制造质量不稳定的瓶颈,打破了外国技术封锁,实现了三代机压气机叶片的稳定制造。研究过程中所积累的经验也为某新型机辊轧叶片的研制打下了坚实的基础。更多还原

【Abstract】 Roller blade has low manufacturing cost and high efficiency.Most importantly,it will improve the mechanical performance,product quality and operating performance which are beneficial for the potential realization of the blade performance.The profiles of HP compressor stator vane of one certain engine are quite complicated.In actual production,H Company encounters some problems like unsuitable process level and unstable blade quality which affect the product quality and reliability.This paper systematically analyzes the defects and shortcomings of the existing rolling process,and carried out a series of targeted research work.Through the application of computer simulation technology,research on flat blank making technology of wool,designed to meet the blade surface and billet rolling precision forming requirements;Through the use of rolling die surface compensation design technology,precision molding of mould cavity;By means of computer aided analysis and adjustment function,improving precision control ability of roll mill;Complete technical characteristics analysis for Rolling forming of Superalloy material;Research on rolling process,the six degree of freedom adjustment technology of blade.The geometrical dimension of the rolling compressor blade,structure performance can all satisfy the requirements of design drawing and relevant specification through above study and improvement.The precision control for rolling process are realized,the quality and stability of the compressor blade are greatly improved;the study and improvement breakthrough the bottleneck of unstable manufacturing quality of rolling blade with complicated profile,break the foreign technology blockade,realize the stable manufacturing of three generation compressor blades.The experiences accumulated in the study also lay a solid foundation for one certain engine rolling blade development.更多还原
