Embodiment 1

[0040] This embodiment provides a mold for preparing a blade tip part, including:

[0041] The connecting part and the main body part 11 connected to each other; the front edge parting surface and the trailing edge parting surface are relatively arranged on both sides of the main part;

[0042] The root groove is arranged on the connecting part and is located between the leading edge parting surface and the trailing edge parting surface.

[0043] In this embodiment, it further includes: a flange 5 arranged on the connecting portion, and a plurality of connecting holes are arranged on the flange, and bolts are connected to the bolt sleeve through the connecting holes. Such as Figure 5 As shown, specifically, the flange 5 itself is integrally formed with the connecting part and is arranged at one end of the cotyledon tip.

[0044]In the blade tip component manufacturing mold provided in this embodiment, the upper surface of the root groove gradually rises along the direction ...

Embodiment 2

[0047] This embodiment provides a method for preparing a blade tip part, which is made through the blade tip part preparation mold provided in Example 1, and the preparation method includes the following steps:

[0048] Place the bolt sleeve 1 on the connecting portion;

[0049] In this embodiment, as an implementation, the plane where the connecting portion is located is slightly lower than the plane where the main body 11 is located. When the bolt sleeve 1 is placed on the connecting portion, the top surface of the bolt sleeve 1 will protrude from the main body 11 .

[0050] Laying and forming operations are performed on the main body portion 11 and the connecting portion to form a cotyledon tip;

[0051] Further, before laying the connecting part, glass fiber cloth is laid on the bolt sleeve 1 , and when the glass fiber cloth is laid, the surface of the glass fiber cloth will remain on the same plane as the main body 11 .

[0052] Specifically, after the placement of the b...

Embodiment 3

[0058] This embodiment provides a method for preparing a blade tip part, which is made by the mold provided in Embodiment 1. In this embodiment, the diameter of the bolt sleeve 1 is smaller than the minimum depth of the connecting part, specifically, as Figure 4 As shown, the connecting portion itself is arranged in a stepped shape, and the horizontal plane where the connecting portion is located is lower than the horizontal plane where the main body portion 11 is located. At the same time, the transition between the connecting portion and the main body 11 is smooth, and when the cotyledon tip is laid on the mold, the continuity of the shape of the obtained cotyledon tip itself can be ensured.

[0059] In this embodiment, the preparation method includes the following steps:

[0060] A plurality of filling blocks 2 are arranged on the connecting portion, a gap is set between two adjacent filling blocks 2, and the gap is determined by the preset position;

[0061] Specifically...

Abstract

The invention provides a blade tip component preparation mold and preparation method and a blade tip component. The preparation method comprises the following steps that bolt sleeves are placed on a connecting part; each bolt sleeve is fixed through a flange of the blade tip component preparation mold; a main body part and the connecting part are laid and formed to form a sub blade tip; and the bolt sleeves are integrally formed in the blade tip component, in the subsequent testing process, the formed bolt sleeves on the blade tip component are directly connected with a testing tool through bolts, and then the testing operation of the blade tip component can be achieved. Compared with the prior art that the bolt sleeves are fixed through a hand lay-up layer, the bolt sleeves are integrally formed in the blade tip component, and the situation that the bolt sleeves are loosened in the testing process can be effectively avoided. Meanwhile, due to the fact that the bolt sleeves are arranged in the sub blade tip, the positioning precision can be controlled through the flange, then connection between the blade tip and a testing platform is guaranteed, and dislocation is avoided.

Description

technical field [0001] The invention relates to the technical field of fan blades, in particular to a preparation process of a blade tip part. Background technique [0002] The fan blade is the part of the fan that mainly bears the wind force. The mechanical properties of the fan blade itself determine the working stability of the fan blade itself. Therefore, after the fan blade is prepared, its own performance test is also very important. [0003] In the prior art, the blade tip part of the blade is generally tested, so as to infer the mechanical properties of the entire blade. The tip part is located at one end of the blade. In the tip part, multiple areas such as web, main beam, and skin are arranged inside the tip part, so that the overall structure of the tip part is very similar to the overall structure of the blade. Therefore The testing effect on the blade can also be achieved by testing the tip part. At the same time, the size of the blade tip itself is small, the...
