Embodiment 1

[0037] see Figure 1-6 , the internal expansion and deployment mechanism used for the filament winding preparation process of cylindrical parts, including a mandrel body 1, the top of the mandrel body 1 is connected with a driving mechanism 2, and the inside of the mandrel body 1 is provided with an inner core mechanism 3, the inner core The mechanism 3 is matched with the drive mechanism 2. The mandrel body 1 and the inner core mechanism 3 are connected with a support mechanism 4. The support mechanism 4 includes a main support group and an auxiliary support group. Both the main support group and the auxiliary support group are connected to the mandrel body. 1 is connected with the inner core mechanism 3, and the support mechanism 4 is also connected with a support shell 5.

[0038] The two ends of the mandrel body 1 are set as a top sleeve 101 and a bottom sleeve 102, and an outer core wedge rod 103 is fixedly connected between the top sleeve 101 and the bottom sleeve 102, a...

Embodiment 2

[0045] see Figure 1-6 The difference in the basis of Embodiment 1 is that both the main support group and the secondary support group include multiple sets of first support rods 401 and second support rods 402, and the middle of the first support rods 401 and second support rods 402 The first support rod 401 and the second support rod 402 are fixedly connected with a spherical rod head 403 on the side close to the mandrel body 1 through the connecting hinge, and the spherical rod head 403 at the end of the first support rod 401 of the main support group is connected to the bottom by rotation. In the support rod installation groove 105 on the sleeve 102, the spherical rod head 403 at the end of the first support rod 401 of the auxiliary support group is rotatably connected in the support rod installation groove 105 on the outer core holder 104, the main support group and the auxiliary support group The end of the first support rod 401 away from the spherical rod head 403 is ro...

Embodiment 3

[0049] Based on Example 1-2 but different in that,

[0050] The method for deploying the internal expansion and deployment mechanism used in the filament winding preparation process of cylindrical pipe fittings includes the following steps:

[0051] S1. Before use, put the disposable rubber tube on the supporting shell 5, and the disposable rubber tube expands with the supporting shell 5;

[0052] S2. Cover the inner wall of the hose to be expanded with soft foam to reduce the interaction between the support shell 5 and the inner wall of the hose;

[0053] S3. Push the device body covered with a disposable rubber sleeve into the hose, adjust the length of the threaded rod 202 relative to the connecting seat 201 through the elastic knob 203, and then adjust the position of the inner core rod 301, so that the support mechanism 4 drives The support shell 5 expands outward;

[0054] S4. After expanding to a suitable degree, stop rotating the elastic knob 203, and realize the tig...

The problems that a design structure in the prior art is complex, the using cost is high, the using method is troublesome, and the working efficiency is affected are solved.

Description

technical field [0001] The invention relates to the technical field of internal expansion and deployment mechanisms, in particular to an internal expansion and deployment mechanism and a deployment method for the carbon fiber winding preparation process of cylindrical parts. Background technique [0002] Filament winding is an important forming process for the production of cylindrical containers and pipe fittings. Because this method is easy to realize mechanization and automation, compared with other forming processes, it has low labor intensity, stable product quality, low production cost, and is widely used. . [0003] During the preparation process of fiber-wound cylindrical parts, special-purpose winding equipment is often used to wrap the fibers impregnated with resin formulations, and then under the tension of the expansion equipment, they are wound on a mandrel with a certain shape according to a certain rule, and then passed through Products are made after being h...
