Abstract

The invention discloses a machining method of an axial flow type compressor stator blade flow channel plate. The machining method comprises the following steps that rough machining is conducted on theouter circle surface of a whole annular forge piece blank, and rough machining on an an inner hole, a T-shaped positioning root key and a drawing rib inclined surface corresponding to one stator blade flow channel plate is sequentially conducted on the inner circle surface of the whole annular forge piece blank; the whole annular forge piece blank is cut according to the position corresponding toeach stator blade flow channel plate so as to finish rough machining on one stator blade flow channel plate blank; heat treatment is conducted on the stator blade flow channel plate blank subjected to rough machining, so that the hardness of the stator blade flow channel plate blank reaches the preset heat treatment hardness of a workpiece; and semi-finish machining and finish machining are sequentially conducted on all parts of the heat-treated stator blade flow channel plate blank, machining on the parts of the stator blade flow channel plate blank is completed, and then machining on the stator blade flow channel plate is completed. The machining method of the axial flow type compressor stator blade flow channel plate is practical, efficient and highly precise, so that the technology gap of machining of the stator blade flow channel plate is solved.

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...
