Embodiment Construction

[0023] Such as figure 1 As shown, the embodiment of the present invention is a composite fan impeller of an axial flow fan, which at least includes the hub of the impeller, the blades and the core, and the hub, the core and the blades are organically combined as a whole.

[0024] In order to describe the present invention in more detail, the production process of the embodiment of the present invention is also described together:

[0025] 1) Making a composite material blade skeleton in a mould;

[0026] 2) making the foamed plastic core of the hub in the mould;

[0027] 3) Processing metal wheel core;

[0028] 4) Set the metal wheel core and the blade skeleton on the foam core of the hub, and uniformly spread the reinforcing material;

[0029] 5) Brush the gel coat with antistatic agent on the surface of the impeller forming mold;

[0030] 6) After the gel coat is cured, set the hub (including blades and metal wheel core) covered with reinforcing materials;

[0031] 7) I...

Abstract

The present invention relates to the improvement in fan, and the integrated fan impeller of composite material includes at least hub, wheel center and vanes. Owing to the integrated structure, the present invention has simple production process, high efficiency, stable quality, light weight and raised safety.

Description

technical field [0001] The invention relates to the improvement of fan Background technique [0002] General fan impellers are all made of metal materials, especially those impellers of axial fans with airfoil blades, and their manufacturing process is very complicated. Since the blades of the fan impeller are designed based on the principle of aerodynamics, the curved surfaces on both sides of the blades are different, and the cross-sectional shapes of different parts of the blades are also different, so it cannot be processed by simple stamping technology. The best way is to use the method of precision casting to make a single blade, and then assemble it to the hub. Both the blade and the hub must be provided with interconnecting devices, as well as positioning and adjustment mechanisms. After the blades and hubs are manufactured, they are assembled together for adjustment, and finally through static balancing and dynamic balancing, the processing of the entire impeller i...
