[0002] Carbon fiber tubes, also known as carbon fiber tubes, are made by pre-impregnating carbon fiber composite materials with styrene-based polyester resin and then curing them by heating.

[0003] Current carbon fiber production mainly uses aluminum alloy tubes as molds. Carbon fiber cloth pre-impregnated with styrene-based polyester resin is wound onto the aluminum alloy tube, and shrink tape is wrapped around it for secure fixation. After heating and curing, it can be demolded. The pre-impregnated carbon fiber cloth and aluminum tube are tightly connected, and with the reinforcement of shrink tape, demolding is relatively difficult. A separate demolding machine needs to be purchased for demolding, and it does not have the function of integrated tooling for easy demolding.

[0004] Now, a novel carbon fiber tube forming tooling that facilitates demolding is proposed to solve the above problems. Utility Model Content

[0013] As a further technical solution of this utility model, two sets of third electric cylinders are installed at the bottom end inside the bottom shell. The output end of the third electric cylinder is fixedly connected to a concave bracket, and a pressing roller is laterally movably connected between the two sides inside the concave bracket.

[0014] As a further technical solution of this utility model, the third electric cylinder is symmetrically distributed about the vertical center line of the concave bracket, the top of the pressing roller is lower than the bottom of the aluminum alloy tube, and the controller and the third electric cylinder are electrically connected.

[0029] Please see Figure 1-7 A carbon fiber tube forming tooling for easy demolding also includes a demolding assembly. The demolding assembly includes a first electric cylinder 3, which is fixedly connected to the rear end of the top of the bottom housing 1. An electric cylinder outer cover 4 is fixedly connected to the top of the first electric cylinder 3. Multiple sets of carbon fiber tube brackets 5 are fixedly connected to the top of the electric cylinder outer cover 4. A spur plate 6 is fixedly connected to the output end of the first electric cylinder 3. A tube end slot 7 is provided at the top of the spur plate 6. A positioning plate 8 is fixedly connected to the rear end of the top left side of the bottom housing 1. A U-shaped groove 9 is opened at the top of the positioning plate 8. A U-shaped extension frame 10 is fixedly connected to the right side of the positioning plate 8. Tube end spline shaft 16 has tube end slots 11 opened at both the front and rear ends.

[0030] The carbon fiber tube brackets 5 are arranged at equal intervals. The controller 2 and the first electric cylinder 3 are electrically connected. The output end of the first electric cylinder 3 passes through the interior of the positioning plate 8. The tube end slot 7 and the tube end groove 11 are matched in shape and size. The U-shaped groove 9 and the U-shaped extension frame 10 are connected internally. The shape and size of the U-shaped groove 9 and the U-shaped extension frame 10 are matched with the shape and size of the aluminum alloy tube 15 externally, which facilitates tube extraction and demolding.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the end slot 11 of the aluminum alloy tube 15 is inserted along the end slot 7 on the horn plate 6. As the first electric cylinder 3 extends outward, the cured carbon fiber tube is blocked by the U-shaped groove 9, and the aluminum alloy tube 15 in the middle is pushed out by the first electric cylinder 3. The carbon fiber tube bracket 5 on the top of the outer shell 4 of the electric cylinder can support the demolded carbon fiber tube. The controller 2 and the first electric cylinder 3 are electrically connected. This technology is existing technology, so it will not be described in detail.

[0032] A first fixing seat 12 is fixedly connected to the front end of the top right side of the bottom housing 1. A second electric cylinder 13 is installed on the right side of the first fixing seat 12. A first clamping plate 14 is movably connected to the output end of the second electric cylinder 13. A second fixing seat 19 is fixedly connected to the front end of the top left side of the bottom housing 1. A reduction motor 20 is installed on the left side of the second fixing seat 19. A second clamping plate 17 is fixedly connected to the output end of the reduction motor 20. An inner spline tube 18 is fixedly connected to the middle position of the first clamping plate 14 and the second clamping plate 17 respectively. The external shape and size of the tube end spline shaft 16 are compatible with the internal shape and size of the inner spline tube 18. The outer diameters of the aluminum alloy tube 15 and the inner spline tube 18 are the same. The controller 2, the second electric cylinder 13, and the reduction motor 20 are electrically connected to facilitate the winding of the prepreg fabric.

[0033] Specifically, such as Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the aluminum alloy tube 15 is placed between the first clamping plate 14 and the second clamping plate 17. The second electric cylinder 13 on the first fixed base 12 extends and pushes the first clamping plate 14 to the left. The two sets of inner spline tubes 18 are then fitted onto the outside of the tube end spline shafts 16 at both ends of the aluminum alloy tube 15. The reduction motor 20 drives the aluminum alloy tube 15 to rotate at a uniform speed through the second clamping plate 17, which facilitates the wrapping of the prepreg fabric. The controller 2, the second electric cylinder 13, and the reduction motor 20 are electrically connected. This technology is existing technology and will not be described in detail here.

[0034] Two sets of third electric cylinders 21 are installed at the bottom of the bottom housing 1. The output end of the third electric cylinder 21 is fixedly connected to a concave bracket 22. A pressing roller 23 is laterally movably connected between the two sides inside the concave bracket 22. The third electric cylinders 21 are symmetrically distributed about the vertical center line of the concave bracket 22. The top of the pressing roller 23 is lower than the bottom of the aluminum alloy tube 15. The controller 2 and the third electric cylinder 21 are electrically connected to facilitate pressing the prepreg fabric.

[0035] Specifically, such as Figure 1 and Figure 2 As shown, during the prepreg wrapping process, the third electric cylinder 21 pushes the concave bracket 22 upward, and the pressure roller 23 presses the prepreg wrapped on the outside of the aluminum alloy tube 15 to make it tightly wound. The controller 2 and the third electric cylinder 21 are electrically connected. This technology is existing technology, so it will not be described in detail.

[0036] Working Principle: In use, the pre-impregnated carbon fiber cloth is first wound around the aluminum alloy tube 15. Before winding, the aluminum alloy tube 15 is placed between the first clamping plate 14 and the second clamping plate 17. The second electric cylinder 13 on the first fixing seat 12 extends, pushing the first clamping plate 14 to the left. The two sets of inner spline tubes 18 are then fitted onto the outside of the spline shafts 16 at both ends of the aluminum alloy tube 15. The reduction motor 20 drives the aluminum alloy tube 15 to rotate at a uniform speed through the second clamping plate 17, facilitating the winding of the pre-impregnated cloth. As the pre-impregnated cloth is wound, the third electric cylinder 21 pushes the concave bracket 22 upward, pressing the pre-impregnated cloth wrapped around the outside of the aluminum alloy tube 15 tightly through the pressure roller 23, making it tightly wound. The aluminum alloy tube 15, together with the heat-cured carbon fiber tube, is inserted along the U-shaped groove 9 on the positioning plate 8. The tube end slot 11 is inserted along the tube end slot 7 on the horn plate 6. As the first electric cylinder 3 extends outward, the cured carbon fiber tube is blocked by the U-shaped groove 9, and the aluminum alloy tube 15 in the middle is pushed out by the first electric cylinder 3. The carbon fiber tube bracket 5 on the top of the electric cylinder outer shell 4 can support the demolded carbon fiber tube.
