Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0029] like Figure 3-7 Shown, the inventive method comprises the following steps:

[0030] a. Input the calculated large-diameter three-dimensional impeller blade shape and hub data into the operation platform to define the blade rotation direction, blade quantity, blade fillet and blade round head, and use the existing operation platform Carry out three-dimensional solid modeling and generate impeller ternary model files;

[0031] b. Clamp the impeller blank on the worktable of the five-axis CNC machining center;

[0032] c. Import the above impeller ternary model file into the existing operating platform, and determine the angles of the two rotation axes A and B of the five-axis CNC machining center in each process according to different parts of the impeller and the twist angle of the blade, and then fix them The two rotary axes of A and B, according t...

Abstract

The invention relates to a manufacturing method for a ternary impeller of a compressor, in particular to a milling method for a ternary impeller with large diameter. The method comprises the following steps: generating a data file from the blade type and hub data of the calculated ternary impeller with large diameter, and inputting the data file into an operation platform; defining the rotating direction of blades, the quantity of the blades, a blade fillet and a blade round head manner; carrying out three-dimensional entity modeling by using the existing operation platform to generate an impeller ternary model file; clamping an impeller blank on a work table of a five-axle numerical control manufacturing center; linking three linear axles and fixing two rotating axles; firstly milling the welding line of the slot body of the short blade, and welding the short blade; after vacuum stress relieving, milling the welding line of the slot body of the long blade; and welding the welding line of the slot body of the long blade and milling the welding line. In the invention, the process time of the impeller is shortened; and compared with the traditional processing method, the process time can be shortened by more than twice, the cost of the cutter is reduced by eight folds, and the service life of machine tool is greatly prolonged.

Description

technical field [0001] The invention relates to a manufacturing method of a ternary impeller of a compressor, in particular to a milling method of a large-diameter ternary impeller. Background technique [0002] As a key part of turbomachinery in aviation, machinery, chemical industry and other industries, ternary impeller is more and more widely used, especially in domestic and foreign fan enterprises, the pace of improving the processing technology of ternary impeller has never stopped. The advanced impeller milling technology is leading the continuous improvement of the level of five-axis CNC machining. [0003] At present, the conventional method of ternary impeller milling is to use high-speed steel cutters to process the blade 2 on the hub 1, and use the side milling method for rough machining to remove most of the allowance. The cutting parameters are small feed and large depth of cut, such as figure 1 shown. In processing, the difficulties are mainly manifested in:...
