Abstract
The invention relates to a processing method of a compressor impeller, which comprises the following steps: A. preparing metal alloy materials according to a designed proportion, blanking, smelting, then casting by using a die, turning an inlet ring position, and then demoulding to obtain an impeller blank; B. carrying out heat treatment on the impeller blank, heating the impeller to quenching, then carrying out grinding, welding line smooth transition, coloring, checking whether the welding line has defect, repair welding, tempering after welding to eliminate welding stress, and finally discharging from the furnace and air cooling; C. after the machine is turned for processing and finish turning, the position of the impeller is corrected; D. carrying out roughening treatment on the surface, and then carrying out surface activation treatment; E. and D, thermally spraying a wear-resistant coating on the surface of the impeller in the step D. The invention not only has unchanged integral strength, but also greatly reduces the loss of raw materials by the new process, reduces the processing difficulty, improves the processing efficiency and saves the cost.
Description
Technical Field
The invention relates to the field of compressor manufacturing, in particular to a method for processing a compressor impeller.
Background
Traditional impeller is many welding after processing together, and the blank comprises wheel lid forging blank and rim plate forging hair bad, and the process flow is: firstly, clamping a wheel cover forging blank on a lathe, and roughly and semi-finely turning the blank to a required shape; then clamping the wheel disc forging blank on a lathe, and roughly and semi-finely turning the wheel disc forging blank to a required shape; and then clamping the wheel disc on a milling machine, milling an impeller on the wheel disc, welding the milled impeller and a wheel cover together, relieving stress, and finally finely turning the impeller. The traditional processing technology has more blank materials, which causes resource waste; the processing procedure is complex, and welding defects exist; the welded impeller has low strength and poor corrosion resistance.
Disclosure of Invention
The invention aims to overcome the defects in the prior art, and provides the processing method of the compressor impeller, which has the advantages that the integral strength is not changed, the loss of raw materials is greatly reduced by a new process, the processing difficulty is reduced, the processing efficiency is improved, and the cost is saved.
The technical scheme for realizing the purpose of the invention is as follows: a method for processing a compressor impeller comprises the following steps:
A. preparing metal alloy materials according to a designed proportion, blanking, smelting, then casting by using a die, turning an inlet ring position, and then demoulding to obtain an impeller blank;
B. carrying out heat treatment on the impeller blank, heating the impeller to quenching, then carrying out grinding, welding line smooth transition, coloring, checking whether the welding line has defect, repair welding, tempering after welding to eliminate welding stress, and finally discharging from the furnace and air cooling;
C. after the machine is turned for processing and finish turning, the position of the impeller is corrected;
D. carrying out roughening treatment on the surface, and then carrying out surface activation treatment;
E. and D, thermally spraying a wear-resistant coating on the surface of the impeller in the step D.
According to the technical scheme, the spot welding reinforcing ring is arranged at the inner circle and the outer circle of the impeller.
After the technical scheme is adopted, the invention has the following positive effects: the invention not only has unchanged integral strength, but also greatly reduces the loss of raw materials by the new process, reduces the processing difficulty, improves the processing efficiency and saves the cost.
