Abstract

The invention discloses a processing method for the stator blade runner plate of an axial-flow compressor, which includes: rough machining the outer circular surface of the whole ring forging blank, and sequentially performing each step on the inner circular surface of the full ring forging blank Rough machining of the inner hole corresponding to the runner plate of the stator vane, the T-shaped positioning root key, and the inclined surface of the tie bars; cutting the whole ring forging blank according to the position corresponding to the runner plate of each stator vane to complete the flow of each stator vane Rough machining of channel plate blanks; heat treatment of the rough-processed stationary vane runner plate blanks, so that the hardness of the stationary vane runner plate blanks reaches the heat treatment hardness of the preset workpiece; heat-treated stationary vane runner plate blanks Each part performs semi-finishing and finishing in turn to complete the processing of the blank of the stator vane runner plate, and then complete the processing of the stator vane runner plate. The invention realizes a practical, high-efficiency, and high-precision processing method for the stator vane flow channel plate of the axial flow compressor, and solves the technical blank in the processing of the stator vane flow channel plate.

Description

technical field [0001] The invention relates to the technical field of axial-flow compressors, in particular to a processing method for a stator vane channel plate of an axial-flow compressor. Background technique [0002] Axial flow compressor is a special kind of compressor equipment. Its rotor has complex structure and many parts. At present, there is no relevant standard for the design, manufacture and inspection of axial flow compressor rotor. Many components of the rotor need to be connected in series on the main shaft, and the design requires high dimensional accuracy and shape accuracy. Among them, the stator vane channel plate is a key and important part in the rotor of the axial flow compressor, and the stator vane channel plate is located on both sides. Between the hubs of the stages, the structure of the runner plate of the vane is as follows: Figures 1 to 3 As shown, the outside is a conical surface and the two sides of the conical surface form an included angl...
