摘要

航空发动机叶段类静子叶片两端无安装板，只有一段空间曲面的叶身型面，后续与其他零组件焊接组合后形成扇形段。某发动机叶段类静子叶片为GH4169 合金，具有型面曲率变化大、前弯后掠、大扭角、进排气边缘成瘦腰形且进、排气边缘厚度差异大等特点。针对叶段类叶片的结构特点，采用精密冷辊轧+ 数控砂带磨+ 非接触式测量的工艺方法，工艺过程主要包括辊轧坯料的平板制坯、辊轧模具的设计制造与检测、进排气边缘R 的数控砂带磨削以及白光测量机对叶片进行全型面测量的工艺方法。采用该工艺方法生产的叶片可以满足几何精度的要求，而且具有优异的组织性能。

Abstract

The stator blade segments of aero-engine only process complex surface without double-ended platform

which are welded with other components subsequently. A typical stator blade segment high-temperature alloy GH4169 is featured with abrupt change in curvature

bowed twisted surface

and obvious change in leading trailing edge radius. A machining approach for the workpiece using the technique of precision rolling

CNC abrasive belt grinding and non-contact detection was proposed. The detailed process mainly includes the flat slab of rolling blank

the design-manufacture-detection of rolling die

the CNC abrasive blet grinding of leading trailing edge

ang white-light interference measurement of blade surface. The blades produced by this process can meet the requirements of geometric accuracy and have excellent microstructure and properties.
