Embodiment 1

[0044] This embodiment provides a method for preparing a preform of a revolving body, wherein, as figure 1 , figure 2 and Figure 6 As shown, the preset rotating body 1 includes an integrally braided and annular first body 11 , and first flanges 12 and second flanges 13 connected to both ends of the first body 11 in the axial direction. Such as Figure 6 As shown, the angles formed by the first flange 12 and the second flange 13 of the rotating body 1 relative to the first axis 15 of the first body 11 are respectively α 1 and alpha 2 , 0°1 ≤90°, 0°2 ≤90°, α 1 and alpha 2 The angles can be the same, for example, α 1 and alpha 2 Both are 90°; or α 1 and alpha 2 different angles, such as α 1 is 45°, α 2 is 60°, α 1 and alpha 2 The specific setting angle is selected according to the needs of the preset rotating body 1. The radii of the first flanging 12 and the second flanging 13 may be equal or unequal, which are all selected according to the actual requirements of...

Embodiment 2

[0076] This embodiment provides a method for preparing the preform of the revolving body 1. Compared with the method for preparing the preform of the revolving body 1 provided in Example 1, the difference lies in:

[0077] In step S10, θ 1 and θ 2 It is not directly selected, but obtained by calculation, and the outer diameter r of any point of the second body of the curling shaft 2 i Inner surface radius R at any point of the first body of the preset rotary body 1 0i Not equal, but can be obtained by selecting the scaling factor.

[0078] Specifically, the included angles formed by the first flange 12 and the second flange 13 of the rotating body 1 with respect to the axis of the first body 11 are respectively α 1 and alpha 2 , 0°1 ≤90°, 0°2 ≤90°; where, θ 1 with alpha 1 Satisfy the following relationship: θ 2 with alpha 2 Satisfy the following relationship: n is the scaling factor, m is the number of turns of the preset third body wound on the crimping shaft, s i...

Embodiment 3

[0089] This embodiment provides a method for preparing a revolving body 1, comprising the following steps:

[0090] The preparation of the revolving body 1 prefabricated body, which adopts the preparation method of the revolving body 1 prefabricated body provided in embodiment 1 or embodiment 2;

[0091] The matrix material is injected into the prefabricated body of the rotor 1 on the mandrel 4, and the matrix material is solidified to obtain the rotor 1.

[0092] Because in the weaving process, the lengths of the third hypotenuse 32 and the fourth hypotenuse 33 are respectively greater than the lengths of the preset first flanging 12 and the preset second flanging 13, generally after the matrix material is solidified, the third The first flange 12 formed by the hypotenuse 32 is trimmed, and the second flange 13 formed by the third hypotenuse 32 is trimmed to obtain the final preset first flange 12 and second flange 13 .

[0093] For the matrix material, the matrix material c...

Abstract

The invention discloses a method for preparing a prefabricated body of a revolving body and a method for preparing the revolving body. The method for preparing the revolving body includes a method for preparing a prefabricated body of a revolving body. The preparation method is to obtain the outer diameter of any point of the second body of the curling shaft by presetting the outer diameter of any point of the first body of the revolving body, and the first flanging and the second flanging are respectively transformed into the first The hypotenuse and the second hypotenuse are used to prepare the curling shaft; the third main body, the third hypotenuse and the fourth hypotenuse are integrally woven on the curling shaft, and the third hypotenuse and the fourth hypotenuse are respectively connected to the axis of the third main body Tilting at a certain angle provides a bending allowance for the outward bending of the third hypotenuse and the fourth hypotenuse, so that the yarn between the two flanges and the first main body is continuous, the two flanges are integrated with the main body, and the substrate After the material is solidified, the connection strength between the first flange, the second flange and the main body is strengthened.

Description

technical field [0001] The invention belongs to the field of three-dimensional braided prefabricated bodies, and in particular relates to a method for preparing a prefabricated body of a revolving body and a method for preparing a revolving body. Background technique [0002] The special-shaped structure of the rotor is a commonly used structure in the design of mechanical parts. It is usually prepared with high-performance fiber-reinforced composite materials as fiber reinforcements. In order to connect the rotor with other components, it needs to be prepared at the axial ends of the rotor. A flanging structure is provided, and the flanging structure is generally perpendicular to the axial direction of the revolving body; or some require the flanging structure to form a certain angle with the axial direction of the revolving body. [0003] In the traditional method of preparing a revolving body with flanging, the main body of the revolving body is woven with high-performanc...
