Problems solved by technology

However, it has been found through research that when the above-mentioned method is used to process the spacer block, since the shape of the spacer block is processed one by one for the square blank of a single spacer block, the sawing material is relatively wasted. In addition, when forging the square material, it is necessary to There are chucks at the bottom that are used to fix the square material when

Example Embodiment

[0033] Example 1:

[0034] The outer circle of the moving vane partitions of the axial flow compressor AV80 series product 4xxx is the same as the outer diameter of the main shaft of the product, and the radius is 400mm. , the maximum thickness is 43.65mm, and it is installed in the tongue and groove with a width of 130mm on the main shaft. The baffle block is suitable for the locking structure of the moving blade with the shaft diameter of the axial compressor being 800mm and the moving blade specification being 125K. For the structure of the moving blade partition block, see figure 1 a, figure 1 b.

[0035] The conventional processing flow is single or multiple one-piece blanking → forging → heat treatment → milling → sawing → processing shape → CNC milling machine processing tenon teeth → vertical turning processing of outer arc → inspection and storage.

[0036] The concrete implementation steps of adopting the partition block processed by the present invention are as ...

Abstract

The invention discloses a machining method of a rotating blade spacer of an axial compressor. In the method, a round bar steel material made of 2Cr13 is adopted for sawing; ring rolling equipment is used for forging to obtain a blank; the blank is successively subjected to rough machining and fine machining of tenon tooth on a CNC lathe to obtain an annular blank; finally, a wire cutting frock is used for carrying out wire cutting on the annular blank to obtain a finished product of spacer; and first article inspection is carried out on the spacer by three coordinates, and qualified products are put in storage. The wire cutting frock comprises a truss with the side surface being a right-angle triangle, the included angle of the upper slope of the truss and the horizontal plane and the installation angel of the spacer are complementary angles, and the upper slope is used for putting the annular blank. The invention combines the characteristics of spacer installation and appearance to design the production method of the spacer, thus simplifying the processing procedures, improving the production efficiency, and increasing the utilization ratio of the forge piece materials toabove 40%. The invention realizes the purpose of energy saving and emission reduction during production and manufacture in the equipment manufacturing industry and obtains the spacer products with favourable identity.

Description

technical field [0001] The invention belongs to the field of equipment manufacturing, and in particular relates to a processing method for a moving blade partition block of an axial flow compression / turbine machine. Background technique [0002] The moving blade partition block of the axial flow compression / turbine machine is a part installed between the roots of adjacent moving blades to maintain the pitch of the moving blades and the width of the flow passage. As the core part of the axial flow compression / turbine unit, the baffle block is assembled along the outer diameter of the main shaft of the rotor and is separated from the corresponding moving blade one by one. Its shape is similar to the root of the corresponding moving blade and is long. Diamond-shaped, the mortise and teeth on it belong to the structure of a rotary body, and the uniformity of the processing quality of the partition blocks directly affects the dynamic balance performance of the entire rotor, the a...
