Description

Technical Field

[0001] This utility model belongs to the field of curing and molding, and specifically relates to a rapid curing and molding device for carbon fiber tubes. Background Technology

[0002] Carbon fiber tubes, with their superior properties such as high strength, lightweight, and corrosion resistance, are increasingly widely used in high-end fields such as aerospace, rail transportation, and new energy equipment. Freshly extruded carbon fiber tubes from the screw extruder die are in a high-temperature softened state (the thermosetting resin system is not fully cross-linked and cured, and the thermoplastic resin system is in a molten or highly elastic state). They require rapid curing and shaping to ensure dimensional accuracy, mechanical properties, and production efficiency. If curing is not timely or deformation occurs during the curing process, defects such as bending, excessive ellipticity, and uneven wall thickness will appear in the carbon fiber tubes, seriously affecting product quality and subsequent assembly and use.

[0003] In existing technologies, the most commonly used rapid curing method for carbon fiber tubes extruded by screw extruders is water cooling. Its core principle is to utilize the high thermal conductivity and fluidity of water. High-pressure cooling water is evenly sprayed onto the outer surface of the high-temperature carbon fiber tube through a ring-shaped spray device, forming a continuous water film covering the tube surface. Through the heat absorption of water evaporation and forced convection heat transfer, the heat of the tube is rapidly carried away, causing the tube temperature to drop below the curing threshold, thus completing the curing and shaping process. This method is widely used in the curing production of various polymer tubes due to its high cooling efficiency, simple equipment structure, and low cost.

[0004] However, in the actual production of carbon fiber tubes, the freshly extruded carbon fiber tubes have extremely low overall strength and rigidity at high temperatures, making them unable to withstand their own weight and the axial tension during the extrusion process. The core function of the annular spray device is to achieve heat exchange through water flow; its structural design lacks effective support for the carbon fiber tubes. During spraying, the carbon fiber tubes rely solely on the traction devices at both ends to maintain their position, leaving the middle section suspended. Under gravity, this makes them highly susceptible to bending and sagging deformation. Furthermore, the impact of the high-pressure water flow further exacerbates the radial vibration of the tube, leading to problems such as localized dents and elliptical cross-sections, severely affecting the straightness and dimensional accuracy of the product.

[0005] Therefore, there is an urgent need for a rapid curing and molding device with cooling capacity and support function to solve the problem of tube bending and deformation caused by insufficient support in the existing annular spray water cooling method. Utility Model Content

[0006] (1) Technical problems to be solved

This addresses the issue that existing annular spray devices, whose core function is heat exchange via water flow, lack effective support for the carbon fiber tubes in their structural design. During spraying, the carbon fiber tubes rely solely on traction devices at both ends to maintain their position, leaving the middle section suspended. Under gravity, this makes them prone to bending and sagging. Furthermore, the impact of high-pressure water flow further exacerbates radial vibration, leading to problems such as localized dents and elliptical cross-sections, severely affecting the straightness and dimensional accuracy of the product.

[0017] (3) Beneficial effects

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This invention, by setting up a cooling mechanism, allows the coolant inside the storage tank to be drawn into the left rubber tube when the water pump inside the storage tank is started. The coolant then enters the inlet pipe from the other end of the left rubber tube, and then flows into the flow channel inside the cooling tube through the upper connecting pipe. It flows along the flow channel between the inner side of the cooling tube and the outer side of the carbon fiber tube inside it, and at the same time absorbs the heat of the carbon fiber tube, so that it cools down and solidifies quickly. During the solidification process, the inner side of the cooling tube supports and limits the movement of the carbon fiber tube to ensure that it does not bend during the solidification process.

[0020] This invention, by setting an extension unit, first removes the caps and metal mounting rings from the right ends of the liquid inlet and outlet pipes of one cooling tube. Then, the metal connecting ring is threaded onto the outer right end of the liquid inlet and outlet pipes. Next, another cooling tube is moved to the right side of the first cooling tube, and the liquid inlet and outlet pipes are in contact with each other. Then, the metal connecting rings on the outer right end of the left liquid inlet and outlet pipes are reversed, so that the metal connecting rings move to the right and are threaded onto the outer left end of the right liquid inlet and outlet pipes. This allows two adjacent cooling tubes to be relatively fixed, thereby allowing the required number of cooling tubes to be spliced ​​in the curing device. The overall length of the fixing device can be adjusted, which in turn changes the time it takes for the carbon fiber tube to be cured to move in the cooling tube, thus changing the cooling efficiency of the curing device, so as to cool and cure carbon fiber tubes of different thicknesses.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] This specific embodiment is a rapid curing and molding device for carbon fiber tubes, and its structural schematic diagram is shown below. Figures 1 to 5 As shown, the device includes a cooling pipe 1, with outer fixing rings 2 welded to the left and right ends of the outer side of the cooling pipe 1, and supporting diagonal rods 3 welded to the front and rear ends of the outer side of the outer fixing rings 2. A cooling mechanism is provided at the outer end of the cooling pipe 1, and the cooling mechanism includes an upper connecting pipe 401 fixedly connected to the upper end of the cooling pipe 1 at equal intervals, with an inlet pipe 402 fixedly connected to the upper end of the upper connecting pipe 401, and a lower connecting pipe 403 fixedly connected to the lower end of the cooling pipe 1 at equal intervals. The lower end is fixedly connected to a drain pipe 404. The upper end of the cooling pipe 1 is provided with inlet holes at equal intervals, and the lower end of the cooling pipe 1 is provided with drain holes at equal intervals. The lower end of the inlet pipe 402 is provided with a connection to the upper connecting pipe 401, and the upper end of the drain pipe 404 is provided with a connection to the lower connecting pipe 403. The inner side of the cooling pipe 1 is provided with spiral flow channels at equal intervals, and the inlet of each flow channel is opened to the inlet hole, and the outlet of the flow is opened to the drain hole.

[0031] The cooling pipe 1 is equipped with a liquid storage tank 405 at its rear. A left rubber tube 406 is installed at the left end of the liquid storage tank 405. The end of the left rubber tube 406 away from the liquid storage tank 405 is connected to the left side of the liquid inlet pipe 402 above the leftmost cooling pipe 1. The end of the pipe joint 411 away from the heat dissipation pipe 407 is connected to the right side of the drain pipe 404 below the rightmost cooling pipe 1. A water pump is installed at the left end of the inside of the liquid storage tank 405. The inside of the liquid storage tank 405 is filled with coolant. One end of the left rubber tube 406 is fixed to the liquid storage tank 405 and is fixedly connected to the drain end of the water pump. The left side of the leftmost cooling pipe 1 in front of the liquid storage tank 405 is located at the extrusion port of the carbon fiber tube extruder. The inside of the cooling pipe 1 and the inside of the flow channel are evenly coated with fluorocarbon paint. When the water pump inside the liquid storage tank 405 is started, the coolant inside the liquid storage tank 405 can be drawn into the left rubber tube 406, and then enter the inlet pipe 402 from the other end of the left rubber tube 406. Then, it flows into the flow channel inside the cooling tube 1 through the upper connecting pipe 401, flows along the flow channel between the inner side of the cooling tube 1 and the outer side of the carbon fiber tube inside it, and absorbs the heat of the carbon fiber tube at the same time, so that it cools down and solidifies quickly. While the solidification work is going on, the inner side of the cooling tube 1 will support and limit the moving carbon fiber tube to ensure that it does not bend during the solidification process.

[0032] In addition, a heat dissipation pipe 407 is installed on the upper right end of the liquid storage tank 405. A rectangular frame 408 is fixedly connected to the outer end of the heat dissipation pipe 407. Heat dissipation fins 409 are welded at equal intervals on the inner side of the rectangular frame 408. A cooling fan 410 is installed at the rear end of the rectangular frame 408. A pipe connector 411 is fixedly connected to the right end of the heat dissipation pipe 407. A right rubber tube 412 is fixedly connected to the right end of the pipe connector 411. The middle part of the heat dissipation pipe 407 is fixedly fixed to the interior of the heat dissipation fins 409 inside the rectangular frame 408. This allows the coolant, which heats up after the carbon fiber tube is cooled and cured, to enter the heat dissipation pipe 407. The heat is then absorbed by the heat dissipation fins 409 at the outer end of the heat dissipation pipe 407. At the same time, the airflow from the cooling fan 410 blows onto the surface of the heat dissipation fins 409, quickly cooling them down. This allows the coolant to be quickly cooled as it passes through the heat dissipation pipe 407 before flowing back into the liquid storage tank 405 for use.

[0033] Cooperate Figure 6As shown, the cooling pipe 1 has an extension unit at its outer end. The extension unit includes a cap 501 connected to the outer ends of the inlet pipe 402 and the outlet pipe 404. External threads are provided on the left and right ends of the outer sides of the inlet pipe 402 and the outlet pipe 404, and internal threads are provided on the inner side of the cap 501. The outer side of the left end of the outlet pipe 404 at the far left end of the front end of the liquid storage tank 405 and the outer side of the right end of the inlet pipe 402 at the far right end of the front end of the liquid storage tank 405 are threaded to the inner side of the cap 501. A metal connecting ring 502 is connected to the outer ends of the inlet pipe 402 and the outlet pipe 404, and a metal mounting ring 503 is also connected to the outer ends of the inlet pipe 402 and the outlet pipe 404. Internal threads are provided on the inner side of the metal connecting ring 502, and the left and right ends of the inner side of the metal connecting ring 502 are threaded to the outer ends of the two adjacent inlet pipes 402 or outlet pipes 404 that are in contact with each other. Thus, by first removing the caps 501 and metal mounting rings 503 from the right ends of the inlet pipe 402 and outlet pipe 404 of one cooling tube 1, and then threading the metal connecting ring 502 onto the outer right end of the inlet pipe 402 and outlet pipe 404, and then moving the other cooling tube 1 to the right side of the first cooling tube 1, with the inlet pipe 402 and outlet pipe 404 in contact with each other, the metal connecting ring 502 on the outer right end of the left inlet pipe 402 and outlet pipe 404 is reversed, so that the metal connecting ring... As 502 moves to the right, it is threaded to the outside of the right end liquid inlet pipe 402 and the left end of the liquid outlet pipe 404, which can fix the two adjacent cooling pipes 1 relatively. This allows the required number of cooling pipes 1 to be spliced ​​in the curing device, and the overall length of the fixing device can be adjusted. This allows the time for the carbon fiber tube to be cured to move in the cooling pipe 1 to be changed, thereby changing the cooling efficiency of the curing device, so as to cool and cure carbon fiber tubes of different thicknesses.

[0034] Among them, a pressure ring 504 is fixedly connected to the inner side of the metal mounting ring 503 away from the metal connecting ring 502 or the drain pipe 404, and a retaining ring 505 is fixedly connected to the outer side of the left rubber tube 406 and the pipe joint 411 away from the liquid storage tank 405 and the heat dissipation pipe 407. The inner side of the metal mounting ring 503 is provided with an internal thread. The outer side of the retaining ring 505 is slidably connected to the inner side of the metal mounting ring 503. The inner side of the pressure ring 504 is slidably connected to the outer side of the left rubber tube 406 and the pipe joint 411. The outer side of the left end of the leftmost inlet pipe 402 at the front end of the liquid storage tank 405 and the outer side of the rightmost outlet pipe 404 at the front end of the liquid storage tank 405 are threadedly connected to the inner side of the metal mounting ring 503. The side of the pressure ring 504 near the inlet pipe 402 or the outlet pipe 404 abuts against the side of the retaining ring 505 away from the inlet pipe 402 or the outlet pipe 404. The left side of the leftmost inlet pipe 402 at the front end of the liquid storage tank 405 and the right side of the rightmost outlet pipe 404 at the front end of the liquid storage tank 405 abut against the side of the retaining ring 505 away from the pressure ring 504. Rubber sealing rings are attached to the left and right sides of the cooling tube 1, the inlet pipe 402 and the outlet pipe 404. Therefore, when the metal mounting ring 503 at the outer end of the left rubber tube 406 or the pipe fitting 411 is threaded to the outside of the liquid inlet pipe 402 and the liquid outlet pipe 404, the retaining ring 505 will be clamped between the pressure ring 504 and the liquid inlet pipe 402 or the liquid outlet pipe 404, thereby fixing the left rubber tube 406 to the outer end of the liquid inlet pipe 402 and the pipe fitting 411 to the outer end of the liquid outlet pipe 404. Through this disassembly method, the left rubber tube 406 and the pipe fitting 411 can be quickly disassembled and assembled when the number of cooling tubes 1 in the curing and molding device needs to be adjusted.

[0035] Working principle: During the cooling and curing of the carbon fiber tube, the extruder extrudes the carbon fiber tube to the right and moves it into the cooling tube 1. At the same time, the water pump inside the liquid storage tank 405 is activated, causing the coolant inside the liquid storage tank 405 to be drawn into the left rubber tube 406. Then, it enters the inlet pipe 402 from the other end of the left rubber tube 406, and then flows into the flow channel inside the cooling tube 1 through the upper connecting pipe 401. It flows along the flow channel between the inner side of the cooling tube 1 and the outer side of the carbon fiber tube that enters it, and at the same time, it cools the carbon fiber tube. The heat is absorbed, causing it to cool down and solidify rapidly. The fixed carbon fiber tube is moved out from the right end of the cooling tube 1. The coolant flowing in the channel cools and solidifies the carbon fiber tube and is discharged from the drain hole into the drain pipe 404. Then it flows into the right rubber tube 412 and enters the heat dissipation tube 407. When it flows in the heat dissipation tube 407, it is cooled by the heat dissipation fins 409 and the cooling fan 410. After being cooled again, it enters the liquid storage tank 405 for continuous cooling and solidification of the carbon fiber tube.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
