Description

Technical Field

[0001] This invention relates to the field of fiber preform technology, and in particular to a device for producing high-performance fiber preforms. Background Technology

[0002] Fiber preforms are fiber composite reinforcements that are pre-formed into desired shapes using sizing agents or textile methods. They are formed into specific shapes through mechanical weaving, needle punching, or three-dimensional weaving techniques. They possess characteristics such as high strength and high temperature resistance and are widely used in aerospace and civilian industries.

[0003] In the production methods of fiber preforms, three-dimensional weaving is one of the important forming methods due to its high weaving efficiency and forming quality. When using a three-dimensional weaving production device, guide rollers are needed to guide the warp yarns and apply pressure to them, so that the warp yarns run accurately and with appropriate tension in subsequent processing, thereby ensuring the quality of fiber preform production. However, in the existing technology, when the guide rollers apply pressure and guide the warp yarns, one guide roller will guide and apply pressure to multiple warp yarns at the same time. As a result, when some warp yarns experience increased tension in subsequent processing, they will affect other warp yarns through the guide rollers. Furthermore, when the warp yarns pass through the guide rollers quickly, heat will be generated at the contact point with the guide rollers. If this heat is not cooled in time, it will affect the performance of the warp yarns, thereby affecting the forming quality of the fiber preform. Summary of the Invention

[0026] The technical solutions of the present invention will now be described with reference to the accompanying drawings. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some well-known technologies. Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0027] like Figures 1 to 7 As shown, an embodiment of the present invention provides a device for producing high-performance fiber preforms, comprising: a first support 1 and a second support 2, wherein the first support 1 is provided with a yarn separating component, a coir lifting component and a weft insertion component, and the second support 2 is provided with a traction component and a weft insertion component, and the yarn separating component is provided with a plurality of guide components; The guiding component is connected to the yarn separating component, and the traction component is connected to the weft insertion component; The guide assembly includes a connecting sleeve 6, a sleeve 7, a rotating wheel 8, a first air hole 9, a second air hole 10, an annular groove 11, an adjusting rod 12, a ball bearing 13, a first triangular pressure block 14, a connecting rod 15, a second triangular pressure block 16, a threaded rod 17, a gear 18, a rack 19, an electric push rod 20, and a mounting component 21.

[0028] It should be noted that the present invention disperses the warp yarns entering the production device through a yarn separating component, guides and tensions the warp yarns passing through the yarn separating component through a guiding component, dissipates the heat generated by the warp yarns passing through the guiding component, absorbs the generated debris, lifts the warp yarns through a hemp-lifting component to arrange the warp yarns into different states and open the warp yarns, inserts the weft yarns through a weft insertion component, pushes the inserted weft yarns to the weft position through a weft beater component and tightens the warp and weft yarns, moves the woven fiber preform through a traction component, and adjusts the warp yarn position fixed on the traction component according to the shape of the fiber preform to adapt to the production requirements of different shaped fiber preforms.

[0029] In one possible implementation, the yarn separating assembly includes a pole 3 fixedly installed on one side of the first bracket 1, and a yarn separating plate 4 is fixedly connected to the top of the pole 3 by bolts. The yarn separating plate 4 has multiple yarn separating holes 5 arranged in a linear array inside. In this process, after the warp yarns have passed through the pre-processing steps and moved to one side of the yarn separating plate 4, the warp yarns can be dispersed and passed through the yarn separating holes 5 on the yarn separating plate 4 to achieve the effect of separating the warp yarns and avoid the warp yarns from getting tangled together, which would affect subsequent processing.

[0030] In one possible implementation, the connecting sleeve 6 is inserted into the inside of the yarn separating plate 4, the mounting member 21 is threaded into the inside of the yarn separating plate 4, the mounting member 21 is inserted into the inside of the connecting sleeve 6, the connecting sleeve 6 is fixedly connected to one end of the sleeve 7, a plurality of rotating wheels 8 are sleeved on the outer wall of the sleeve 7, the interior of each of the plurality of rotating wheels 8 is provided with a plurality of first air holes 9 in a circumferential array, the sleeve 7 is provided with a plurality of sets of second air holes 10 corresponding to the number of rotating wheels 8, the interior of each of the plurality of rotating wheels 8 is provided with two annular grooves 11, one of the annular grooves 11 is connected to the first air hole 9, the interior of the sleeve 7 is provided with four adjusting rods 12 in a circumferential array, the outer wall of each of the four adjusting rods 12 is provided with ball bearings 13 corresponding to the number of rotating wheels 8, another annular groove 11 inside the rotating wheel 8 is sleeved on the outer wall of the corresponding ball bearing 13, the four adjusting rods Multiple first triangular pressure blocks 14 are fixedly connected to one side of each of the four adjusting rods 12. The connecting rod 15 is inserted between the four adjusting rods 12. The outer wall of the connecting rod 15 is fixedly connected to a second triangular pressure block 16 corresponding to the number of balls 13 on the four adjusting rods 12. The connecting rod 15 is inserted into the inside of the sleeve 7. The connecting rod 15 is inserted into the inside of the yarn separating plate 4. One end of the connecting rod 15 is rotatably connected to the threaded rod 17. The threaded rod 17 is threadedly connected to the inside of the yarn separating plate 4. The side of the threaded rod 17 away from the connecting rod 15 is fixedly connected to the gear 18. The outer wall of the gear 18 meshes with the rack 19. The inner wall of the rack 19 is fixedly connected to the output shaft end of the electric push rod 20. The electric push rod 20 is fixedly installed on the outer wall of the yarn separating plate 4. The rack 19 is slidably connected to the outer wall of the yarn separating plate 4. The connecting sleeves 6 of the multiple guiding components are all connected to the diversion channels of the air pipe 22. In this process, after the warp yarn passes through the yarn separating assembly, the warp yarn can be wound around the outer wall of different rollers 8. After the tension of the warp yarn changes after the rear pull-up, the warp yarn will only drive the corresponding roller 8 to rotate on the outer wall of the corresponding ball 13 on the sleeve 7, without affecting the tension of other warp yarns. This reduces the impact of the change in warp yarn tension on the remaining warp yarns, improves the stability of the warp yarn processing process, and thus improves the quality of the fiber preform after production. Furthermore, when the warp drives the corresponding rotating wheel 8 to rotate, generating heat and debris, the vacuum pump 23 can be activated. The vacuum pump 23 extracts the gas inside the connecting sleeve 6 of different guide components through the air pipe 22, creating a negative pressure inside the cavity formed by the connecting sleeve 6, the sleeve 7, and the adjusting rod 12. The gas is then extracted from the contact area between the rotating wheel 8 and the warp through the first air hole 9, the second air hole 10, and an annular groove 11 corresponding to the first air hole 9. The high temperature generated by the rapid rotation of the rotating wheel 8 and the warp, as well as the debris formed by the contact between the warp and the rotating wheel 8, are adsorbed by the negative pressure and finally enter the cavity formed by the connecting sleeve 6, the sleeve 7, and the adjusting rod 12. The debris is then discharged into the vacuum pump 23 through the cavity and the air pipe 22, and discharged through the air outlet pipe. This achieves the effect of treating the high temperature and debris generated during the contact transmission between the warp and the rotating wheel 8, preventing the high temperature from affecting the performance of the warp and preventing the debris from scattering and affecting the processing quality of the fiber preform. Furthermore, when it is necessary to adjust the warp tension, the electric push rod 20 can be controlled to work, so that the electric push rod 20 drives the gear 18 to rotate through the rack 19, so that the gear 18 drives the threaded rod 17 to rotate along the inside of the yarn separating plate 4, so that the threaded rod 17 pulls the connecting rod 15 to slide along the length direction of the sleeve 7, so that the connecting rod 15 drives the second triangular pressure block 16 to squeeze the first triangular pressure block 14 of the four adjusting rods 12, so that the four adjusting rods 12 move away from each other and outward, thereby causing the adjusting rods 12 to drive the ball 13 to increase the pressure on the annular groove 11 on the rotating wheel 8, so that the friction between the rotating wheel 8 and the ball 13 increases, thereby changing the resistance of the warp pulling the rotating wheel 8 to rotate, so as to achieve the effect of changing the warp tension through friction, thereby adapting to the processing tension of different fiber warp yarns; Furthermore, by assembling the guide assembly from multiple components, the processing difficulty of the guide assembly can be reduced, allowing each component of the guide assembly to be processed individually before assembly, which facilitates production.

[0031] In one possible implementation, the palm fiber lifting assembly includes a housing 24 fixedly mounted on the top of the first support 1, a palm fiber lifting structure 25 fixedly mounted inside the housing 24, a plurality of heddles 26 fixedly connected inside the palm fiber lifting structure 25, the plurality of heddles 26 being inserted into the inside of the housing 24, and an air pump 23 fixedly mounted inside the housing 24, with an air pipe 22 connected to the air inlet of the air pump 23. When the warp yarn passes through the yarn separating assembly and the guiding assembly, it can enter the needle hole of the heddle 26. When the heddle lifting structure 25 is working, multiple heddles 26 can be raised or lowered individually, so that the warp yarns passing through the needle hole of the heddle 26 can be arranged into different shapes, diversifying the form of the warp yarns forming the weave, laying the foundation for the fiber preform forming of irregular parts, and opening the warp yarns to facilitate weft insertion.

[0032] In one possible implementation, the weft insertion assembly includes a weft feeding and weft splicing structure 27 fixedly installed on the outer wall of the first support 1, and a weft insertion member 28 is fixedly installed on one side of the weft feeding and weft splicing structure 27. In this process, after the warp yarns are opened by the weft-raising component, the weft feeding and weft insertion structure 27 and the weft insertion component 28 can work together to introduce the weft yarns between the warp yarns.

[0033] In one possible implementation, the weft insertion assembly includes a weft insertion frame 29 disposed on one side of the heald 26. A telescopic guide rod 30 and a telescopic rod 31 are fixedly connected to the side of the weft insertion frame 29 away from the heald 26. The telescopic guide rod 30 and the telescopic rod 31 are both fixedly installed inside the second bracket 2. A cylinder 32 is provided at the end of the telescopic rod 31 away from the heald 26. The cylinder 32 is fixedly installed on the outer wall of the second bracket 2. In this process, after the weft yarn is introduced into the warp yarn, the cylinder 32 can control the telescopic rod 31 to retract, causing the telescopic rod 31 to pull the weft-beating frame 29 towards the traction component and squeeze the telescopic guide rod 30 to retract. After the weft-beating frame 29 pushes the weft yarn to the weft opening position, the weft-beating frame 29 presses the weft yarn tightly at the weft opening, so that the warp and weft yarns are tightened at the weft opening, making the warp and weft yarns fit together tightly. After the warp and weft yarns are tightened, the cylinder 32 controls the telescopic rod 31 to push the weft-beating frame 29 to reset, waiting for subsequent work.

[0034] In one possible implementation, the traction assembly includes two electromagnetic slide rails 33 fixedly mounted on the outer wall of the second bracket 2. Slider 34s are slidably connected to the outer walls of both electromagnetic slide rails 33. A support frame 35 is fixedly mounted on the top of each slider 34. The support frame 35 is slidably connected to the outer walls of the telescopic guide rod 30 and the telescopic rod 31. An adjustment structure 36 is fixedly mounted on the top of the support frame 35. Multiple partitions 37 are slidably connected inside the support frame 35. A clamping screw 38 is threadedly connected inside the support frame 35. The clamping screw 38 abuts against the outer wall of the outermost partition 37. Two connectors 39 are slidably connected between every two partitions 37. Connecting wires 40 are fixedly connected to the outer walls of each of the multiple connectors 39. The connecting wires 40 are fixedly connected inside the adjustment structure 36. In this process, after the warp thread passes through the needle hole of the heddle 26, the warp thread can be pulled and moved until it is fixed on multiple connectors 39 to secure it. Furthermore, when it is necessary to adjust the production shape of the fiber preform, the clamping screw 38 can be loosened and the adjustment structure 36 can be controlled to work, so that the adjustment structure 36 can individually control multiple connecting lines 40 to pull the corresponding connecting parts 39 up or down, so that multiple connecting parts 39 form arc shapes with different curvatures, thereby forming fiber preform production weaves with different curvatures, thereby achieving the effect of producing irregularly shaped fiber preforms, improving the applicability of the production device, so as to adjust it according to the production requirements of different irregularly shaped fiber preforms; Specifically, during the production of the irregularly shaped fiber preform, the heaving assembly can lift the warp threads to create an opening, allowing the weft insertion assembly to introduce the weft threads into the warp threads. Then, the heaving assembly can control the warp threads to form a weft opening shape that is the same as the weft opening shape formed by the connecting piece 39 of the traction assembly. The weft thread is then tightened to the weft opening position of the traction assembly by the weft insertion assembly, forming the preliminary structure of the irregularly shaped fiber preform. Then, the slider 34 drives the support frame 35 to move away from the heaving assembly along the electromagnetic slide rail 33, so that the distance between the heaving assembly and the connecting piece 39 gradually increases as the irregularly shaped fiber preform is produced, ensuring that the effective distance between the heaving assembly and the connecting piece 39 remains fixed.

[0035] In summary, the high-performance fiber preform production device designed in this invention disperses the warp yarns entering the production device through a yarn separating component, guides and tensions the warp yarns passing through the yarn separating component, dissipates the heat generated by the warp yarns passing through the guide component, absorbs the generated debris, lifts the warp yarns through a hemp-lifting component to arrange the warp yarns into different states and open the warp yarns, inserts the weft yarns through the warp yarns through a weft insertion component, pushes the inserted weft yarns to the weft position through a weft beater component and tightens the warp and weft yarns, moves the woven fiber preform through a traction component, and adjusts the warp yarn positions fixed on the traction component according to the shape of the fiber preform to adapt to the production requirements of different shaped fiber preforms.

[0036] The beneficial effects of the technical solutions provided in the embodiments of the present invention include at least the following: In this invention, the guiding component can individually guide and drive multiple warp threads. An abnormal increase in the tension of one warp thread will not affect the tension of the remaining warp threads, improving the stability of the warp processing and thus improving the quality of the fiber preform after production. It can effectively handle the high temperature and debris generated during the contact transmission process between the warp threads and the rotating wheel 8, preventing high temperature from affecting the performance of the warp threads and preventing debris from scattering and affecting the processing quality of the fiber preform. It can change the tension of the warp threads to adapt to the processing tension of fiber warp threads of different materials. At the same time, the lifting component and the traction component work together to change the weave shape of the fiber preform, thereby enabling the production of different types of irregularly shaped fiber preforms.
