Machining technique for impeller of ventilator

Abstract

The invention discloses a machining technique for an impeller of a ventilator. The machining technique includes the following steps: 1) material preparation; 2) rear disc positioning: fixing a rear disc on a platform; 3) point welding of vanes; 4) checking: checking if the perpendicularity of the vanes, the size of the vanes, and an outer circle of the vanes meet a drawing; 5) point welding of a front disc: performing point welding after alignment and compression; 6) checking: checking if the rotary direction and the size of the vanes meet the demands; 7) welding: firstly welding fillet weld joints between the vanes and the rear disc, secondly welding fillet weld joints between the vanes and the front disc, and performing symmetrical welding to ensure the flatness of the rear disc; 8) hub riveting; 9) shape correcting; 10) vibration aging processing; 11) lathing; 12) checking; 13) balancing; and 14) surface coating: clearing oil stains, excessive metal, burrs, and rust on a fan, performing surface coating according to the demands, and meeting the demands of products; the machining technique is simple, can avoid repeated processes, improve the working efficiency and the properties of all aspects, prolong the service life of the impeller of the ventilator, and enhance the market competitiveness.

Description

technical field [0001] The invention relates to a process for processing fan impellers. Background technique [0002] At present, the processing technology of fan impellers is relatively complicated, and there is no unified specification and standard, resulting in uneven quality of the produced fan impellers. Many repeated processes also make the production efficiency low, increase the labor burden of workers, and make the products market competitiveness is not high. For some operators who have just entered the industry, there is no clear method and process, resulting in frequent mistakes and omissions during operation, and may even cause serious consequences. Contents of the invention [0003] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is to provide a fan impeller processing technology, which is simple, eliminates many repetitive procedures, improves work efficiency, and can improve the performance...
