Description

Technical Field

[0001] The utility model relates to the technical field of fan blade equipment, in particular to an integrated stamped fan blade. Background Art

[0002] Stamped wind blades refer to blades manufactured through a stamping process. The stamping process is a processing method that uses a mold to apply pressure to metal sheets on a press to cause them to undergo plastic deformation or separation, thereby obtaining parts of the desired shape and size. In wind blade manufacturing, the stamping process has the advantages of high efficiency, high precision, and low cost, and is therefore widely used.

[0003] Although the above-mentioned existing stamped fan blades have certain strength, the external protection and corrosion resistance of the stamped fan blades are insufficient. When impacted by external objects or corroded by liquids, the fan blade body is easily damaged, thereby reducing the subsequent service life. Therefore, an integrated stamped fan blade is urgently needed to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of the utility model is to provide an integrated stamped fan blade to solve the problems raised in the above background technology.

[0006] A connecting seat, wherein the connecting sleeve and the connecting seat are integrally arranged, and the connecting seat is fixedly arranged on the upper end surface of the connecting sleeve;

[0007] Wind blades are fixedly arranged at equal intervals on the side end surface of the connecting sleeve.

[0008] Preferably, an arc-shaped surface is provided on the upper end surface of the wind blade near the upper end.

[0009] Preferably, a connecting seat sleeve shell is fixedly provided on the outer end surfaces of the connecting ferrule and the connecting seat, and the connecting seat sleeve shell can effectively improve the protection of the connecting ferrule and the outside of the connecting seat.

[0010] Preferably, a wind blade cover is fixedly provided on the outer end surface of the wind blade, and the wind blade cover can effectively improve the protection of the outside of the wind blade.

[0011] Preferably, a cross positioning groove for positioning is provided on the top of the inner end surface of the connecting seat, which can facilitate quick and accurate positioning of the fan blades during subsequent installation.

[0012] Preferably, the connecting seat shell and the wind blade shell are integrally arranged, and the material of the connecting seat shell and the wind blade shell is nickel-based alloy, which can effectively improve the high temperature resistance, corrosion resistance and oxidation resistance of the outside of the wind blade, thereby improving the subsequent service life of the wind blade.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model provides a connecting seat shell and a wind blade shell, and the connecting seat shell can provide all-round protection for the outside of the connecting sleeve, while the wind blade shell can provide all-round protection for the outside of the wind blade, effectively improving the protection performance of the outside of the wind blade. At the same time, the connecting seat shell and the wind blade shell are made of corrosion-resistant materials and are integrally molded and stamped with the wind blade, the connecting sleeve and the connecting seat, thereby maximizing the corrosion resistance and protection of the outside of the wind blade, thereby increasing the overall service life of the wind blade.
