Description

Technical Field

[0001] The present invention relates to the technical field of new material processing, and particularly to a fully automatic carbon fiber tube winding device and a winding method. Background Art

[0002] Carbon fiber refers to a special fiber composed of carbon elements with a carbon content of more than 90%. Its high-temperature resistance ranks first among all chemical fibers. It is made from acrylic fibers and viscose fibers through high-temperature oxidation and carbonization. It is an excellent material for manufacturing high-tech equipment such as aerospace. It has characteristics such as high temperature resistance, anti-friction, electrical conductivity, thermal conductivity, and corrosion resistance. Its shape is fibrous, soft, and can be processed into various fabrics. Due to the preferred orientation of its graphite microcrystal structure along the fiber axis, it has high strength and modulus along the fiber axis direction. The density of carbon fiber is small, so its specific strength and specific modulus are high. The main use of carbon fiber is as a reinforcing material to be compounded with resins, metals, ceramics, and carbon to manufacture advanced composite materials. Carbon fiber reinforced epoxy resin composite materials have the highest specific strength and specific modulus among existing engineering materials.

[0003] When processing carbon fiber into composite pipe fittings, traditional manual processes are generally used. The carbon fiber composite wire harness is cut into a preset length, and then manually attached to the mandrel tube. After heating and curing and then demolding, carbon fiber composite pipe fittings are obtained. The traditional manual process has low efficiency, and the length of the produced carbon fiber composite pipes is limited. Summary of the Invention

During the winding operation, one end of the carbon fiber composite wire harness in the feeding mechanism is pulled out and adhered to one end of the mandrel 7. The rotating mechanism drives the mandrel 7 to rotate, and at the same time, the second electric slide rail 8 drives the feeding mechanism on the moving frame 9 to move along the left and right directions, so as to wind the carbon fiber composite wire harness around the surface of the mandrel 7 in a spiral shape. Finally, the wound carbon fiber composite pipe is heated. After the carbon fiber composite wire bundle is cured and formed into a carbon fiber composite pipe, the carbon fiber composite pipe can be removed from the mandrel; the winding process of the present invention has a high degree of automation, the pipe winding is uniform, and the product quality is improved.

[0029] At the same time, the tightening mechanism can move along with the moving column 6, so that mandrels of different lengths can be fixed, pipes with longer lengths can be produced, and they can also be cut according to customer requirements, reducing costs and improving flexibility.

[0030] See Figure 1 、 Figure 2 As shown in the figure, the rotating mechanism includes a pneumatic chuck 21 rotatably arranged on the left column 2 for clamping the mandrel 7 and a rotating motor 22 for driving the pneumatic chuck 21 to rotate.

[0037] When the mold core 7 is installed, first open the pressing rollers 75 on both sides (as shown in Figure 4 ), then place the mold core 7 between the two lower rollers 73, and finally release the pressing rollers 75. Through the action of the torsion spring, the pressing rollers 75 are pressed on the mold core 7 to avoid accidental jumping of the mold core and improve its stability during rotation.

[0038] In the present invention, extension support seats 81 extending in the front-rear direction are arranged at the lower ends of both the left upright column 2 and the right upright column 3. By arranging the extension support seats 81 on both sides, the stability of the device can be improved.
