Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of aircraft heat protection components, and particularly relates to a rudder fabric profiling weaving device and a rudder fabric profiling weaving method. BACKGROUND

[0002] With the progress of technology, the environment faced by aircraft is becoming more and more severe, and higher requirements are put forward for heat protection components. The aircraft heat protection component needs to have higher structural strength and ablation resistance, and therefore needs to be integrally formed to simultaneously meet the aerodynamic and ablation resistance functions. Three-dimensional woven stereoscopic fabric has structural integrity and is increasingly applied in the field of aircraft.

[0003] The rudder surface structure is the control surface of the aircraft. The aircraft generally has three direction control surfaces. The horizontal direction is the elevator, that is, the horizontal tail, which is responsible for controlling the ascent and descent of the aircraft. The vertical direction is the rudder, which is generally on the vertical tail, and is responsible for controlling the heading of the aircraft. The oblique direction is the aileron, which is generally at the end of the aircraft wing, and is responsible for controlling the inclination of the aircraft. In the profiling weaving of the stereoscopic fabric, a stereoscopic fabric positive mold core mold is generally first made, and the core mold is placed in the center of the weaving platform for weaving. At present, the rudder surface structure is generally woven by vertical warp yarn zero tension. For the three-dimensional woven integrally formed rudder surface structure, the rudder fabric leading edge and the rudder surface thickness are different, and the shape and parameters are different. Since there is no corresponding control device, such as warp density and weft density, the weaving parameters are controlled and adjusted by manual operation. The parameters arranged by different weaving personnel differ greatly, resulting in uneven warp density and weft density, poor product quality consistency; the weft yarn is inclined during weaving due to the thick thickness of the fabric leading edge, and the weft yarn is unevenly arranged along the thickness direction; the warp yarn is woven by zero tension, and the warp yarn is intertwined and not easy to separate; the inner and outer arc lengths of the leading edge are inconsistent, and different weaving personnel will cause different operation methods, resulting in different leading edge shapes, and causing problems such as rich resin during compounding.

[0004] Therefore, it is necessary to provide a rudder fabric profiling weaving device and a weaving method to improve product quality and production efficiency. SUMMARY

[0012] Preferably, the yarn-hanging pins on the rudder surface of the rudder fabric on the contoured yarn-hanging plate body are parallel to each other and arranged at equal intervals; the yarn-hanging pins on the leading edge warp of the rudder fabric on the contoured yarn-hanging plate body are arranged in a fan-shaped ring, and the inner arc length of the fan ring between adjacent yarn-hanging pins is equal.

[0013] Preferably, the conforming reed includes a conforming reed body and a plurality of reed blades disposed on the conforming reed body, the reed blades being used for weft insertion; the cross-sectional shape and size of the structure formed by the plurality of reed blades are the same as the cross-sectional shape and size of the twill fabric product.

[0014] Preferably, the reeds on the rudder surface of the rudder fabric on the conformal steel reed body are arranged parallel to each other and at equal intervals; the reeds on the leading edge of the rudder fabric on the conformal steel reed body are arranged in a fan-shaped ring, and the inner arc length of the fan ring between adjacent reeds is equal.

[0017] Another aspect of the present invention provides a method for weaving a rudder fabric using a rudder fabric conformal weaving apparatus, comprising the following steps:

[0018] S1. Yarn is fed onto the rudder fabric conformal weaving device according to the warp yarn arrangement parameters of the rudder fabric. One end of the warp yarn is hung on the conformal yarn hanging plate, and the other end passes through the conformal reed and is connected to the tension line of the warp feeding mechanism.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] The rudder fabric weaving device and weaving method of the present invention can be weft-beaten by a weft-beating reed. The weft-beating reed moves along the length direction of the weft-beating mandrel. The weft-beating reed is perpendicular to the direction of the weft-beating mandrel and parallel to the fabric weft opening. After the weft-beating is completed by the weft-beating reed, the weft opening is neat and there is no weft skew due to manual weft winding during vertical weaving. The internal density of the fabric is uniform.

[0024] Since the leading edge of the rudder fabric has an uneven thickness and the rudder surface is relatively wide, it is necessary to adjust the shape and control the warp and weft density. The rudder fabric contour weaving device and weaving method of the present invention can control the shape, warp density and weft density of the leading edge of the rudder fabric through the contour reed, so that the warp yarns of the leading edge are evenly arranged and the shape of the leading edge is consistently controlled. This avoids the problem of large differences in parameters between different personnel and poor quality consistency when manually adjusting and controlling, thereby improving work efficiency and improving the uniformity of fabric density and the consistency of weaving quality.

[0025] The rudder fabric contour weaving device and weaving method of the present invention provide tension lines for connecting the warp yarns of the rudder fabric, which can provide the tension required for the warp yarn layering opening. The warp yarns will not become entangled with each other due to zero tension of the warp yarns during vertical weaving, thus improving the layering efficiency.

[0026] The rudder fabric contour weaving device of the present invention has a simple structure and stable operation. Based on this design, rudder fabrics of different specifications and shapes can also be woven by installing mandrels of different specifications and shapes. It has strong applicability and a wide range of engineering applications. Attached Figure Description

Detailed Implementation

[0037] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1

[0039] like Figure 1 As shown, a rudder fabric contour weaving device according to this embodiment includes:

[0040] 1. Core mold support, 2. Yarn hanging support, 3. Steel reed support, 4. Contouring yarn hanging plate, 5. Steel reed seat, 6. Contouring steel reed, and 7. Contouring core mold;

[0041] The core mold support 1 is provided with a first horizontal moving mechanism, and the conforming core mold 7 is provided on the first horizontal moving mechanism. The first horizontal moving mechanism is used to make the conforming core mold 7 reciprocate along its length direction. The yarn hanging support 2 is provided with a conforming yarn hanging plate 4, which is used to hang the warp yarn. The reed support 3 is provided with a second horizontal moving mechanism, and the reed seat 5 is provided on the second horizontal moving mechanism. The second horizontal moving mechanism is used to make the reed seat 5 reciprocate along the length direction of the conforming core mold 7. The conforming reed 6 is provided on the reed seat 5 and is perpendicular to the length direction of the conforming core mold 7.

[0042] In the rudder fabric contour weaving device of this invention, when performing rudder fabric contour weaving, the yarn is first fed onto the rudder fabric contour weaving device according to the selected rudder fabric warp yarn arrangement parameters (including the number of warp yarns per layer, the number of warp yarn layers, etc.). One end of the warp yarn is hung on the yarn hanging bracket 2, and the other end passes through the contour reed and connects to the tension line of the warp feeding mechanism to provide a certain tension to the warp yarn. Then, the contour mandrel 7 is moved by the first horizontal moving mechanism to the weft winding position. The warp yarns are manually layered, and the weft yarns are wound layer by layer onto a molded mandrel. During the weft winding process, the molded mandrel controls the internal dimensions of the rudder fabric. After the weft winding is complete, the molded mandrel is moved to the weft winding position by a first horizontal moving mechanism. Then, a second horizontal moving mechanism moves the reed holder along the length of the molded mandrel, and the reed on the reed holder beats the weft until the weft density is acceptable. This process of layering and winding the warp yarns layer by layer, beating the weft, is repeated until the rudder fabric is woven, resulting in the desired weft density. Figure 8 The rudder fabric product 13 is shown. During operation, the position of the yarn hanging plate is fixed; as the weft insertion position changes, the position of the reed support can be manually moved to change the weft insertion position. The rudder fabric contour weaving device of this embodiment can perform weft insertion using a contour reed. The contour reed 6 moves along the length direction of the contour mandrel 7. The contour reed 6 is perpendicular to the direction of the contour mandrel 7 (i.e., the fabric length direction) and parallel to the fabric weft opening. After the contour reed 6 completes the weft insertion, the weft opening is neat, and there is no weft skew due to manual weft winding during vertical weaving. The internal density of the fabric is uniform. Furthermore, since the leading edge of the rudder fabric has an uneven thickness and the rudder surface is wide, it is necessary to adjust the shape and control the warp and weft density. This embodiment of the invention... The rudder fabric contour weaving device, for example, controls the shape, warp density, and weft density of the rudder fabric's leading edge via a contour reed. This ensures uniform warp yarn arrangement and consistent leading edge shape control, avoiding the problem of inconsistent quality caused by large parameter differences between different personnel during manual adjustment. It improves work efficiency, fabric density uniformity, and weaving quality consistency. The tension lines connecting the rudder fabric warp yarns provide the tension required for warp layer opening, preventing the tension lines from tangling due to zero warp tension during vertical weaving, thus improving layering efficiency. This rudder fabric contour weaving device has a simple structure and stable operation. Based on this design, different specifications and shapes of rudder fabrics can be woven by installing mandrels of different sizes and shapes, making it highly adaptable and widely applicable in engineering.

[0043] Among them, the core mold bracket and the yarn hanging bracket are fixed, while the reed bracket is movable. As the weft insertion position changes, the position of the reed bracket can be manually moved to change the weft insertion position.

[0044] In some embodiments, the first horizontal moving mechanism is used to reciprocate the contour mold 7 along its length. The horizontal moving mechanism is prior art; any mechanism capable of driving the contour mold to reciprocate along its length can implement this invention. Preferably, the first horizontal moving mechanism includes a forward / reverse motor 8, a lead screw 9, and a lead screw nut; one end of the lead screw 9 is rotatably connected to one end of the mold support 1, the forward / reverse motor 8 is located at the other end of the mold support 1, and the other end of the lead screw 9 is connected to the output shaft of the forward / reverse motor 8; the lead screw nut is threadedly connected to the lead screw 9, and the contour mold is connected to the lead screw nut. The forward / reverse motor drives the lead screw to rotate forward or reverse, and the lead screw and lead screw nut cooperate to drive the contour mold to reciprocate along its length. Specifically, the lead screw is arranged in a direction parallel to the length of the contour mold; the drive shaft of the forward / reverse motor 8 is provided with a gear that meshes with the lead screw, and the gear cooperation drives the lead screw to rotate.

[0045] Preferably, there are two lead screws 9 and two lead screw nuts that cooperate with them. The two lead screws are arranged in parallel, and the contour mandrel is threadedly connected to the two lead screws through the two lead screw nuts respectively. Using two lead screws to drive the contour mandrel to move makes the movement of the contour mandrel more stable.

[0046] In some embodiments, the second horizontal moving mechanism is used to reciprocate the reed seat 5 along the length of the contour mandrel 7. The horizontal moving mechanism is existing technology; any mechanism capable of driving the reed seat to reciprocate along the length of the contour mandrel can implement this invention. Preferably, the second horizontal moving mechanism includes a linear guide rail 10, a slider 11, and a connecting block 12; the linear guide rail 10 is mounted on the reed support 3; the slider 11 is slidably mounted on the linear guide rail 10; the connecting block 12 is connected to the slider 11; and the reed seat 5 is connected to the connecting block 12. The linear guide rail drives the slider to reciprocate along the length of the contour mandrel, causing the contour reed on the reed seat to beat the introduced weft yarn, adjusting the regularity of the weft yarn and controlling the weft density and warp density. Specifically, the linear guide rail is arranged parallel to the length of the contour mandrel; the reed seat 5 is connected to the connecting block 12 via a pin.

[0047] Specifically, such as Figure 7 As shown, the outer surface of the contour mold 7 is consistent with the inner surface shape and size of the rudder fabric product.

[0048] Preferably, there are two linear guide rails 10, two sliders 11, and two connecting blocks 12, with the two linear guide rails arranged parallel to each other on both sides of the reed support. Using two linear guide rails 10 to drive the movement of the reed seat makes the movement of the reed support more stable.

[0049] Preferably, such as Figure 5 , 6As shown, the contoured yarn hanging plate 4 includes a contoured yarn hanging plate body 41 and multiple yarn hanging pins 42 disposed on the contoured yarn hanging plate body 41. Multiple warp yarns can be hung from top to bottom on each yarn hanging pin 42. After the yarn hanging pins 42 on the contoured yarn hanging plate body 41 hang the warp yarns, the shape and size of the cross-section of the structure formed by all the warp yarns are the same as the cross-sectional shape and size of the rudder fabric product. Here, the cross-section refers to the surface perpendicular to the length direction of the rudder fabric; that is, the shape and size of the lateral projection surface of all the warp yarns after the yarn hanging pins 42 on the contoured yarn hanging plate body 41 hang the warp yarns are the same as the lateral projection surface shape and size of the rudder fabric product. Specifically, the yarn hanging pins 42 are welded onto the contoured yarn hanging plate body 41.

[0050] Preferably, the outer surface of the contour hanging board body 41 has the same shape and size as the inner surface of the rudder fabric, and the hanging pins are set on the outer surface of the contour hanging board body.

[0051] Preferably, such as Figure 6 As shown, the warp yarns on the rudder surface of the rudder fabric on the main body 41 of the contoured yarn hanging plate are arranged parallel to each other and at equal intervals; the warp yarns on the leading edge of the rudder fabric on the main body 41 of the contoured yarn hanging plate are arranged in a fan-shaped ring, and the inner arc length of the fan ring between adjacent yarn hanging pins is equal. The yarn hanging pins on the main body of the contoured yarn hanging plate are used to hang the warp yarns. One yarn hanging pin hangs one or several rows of warp yarns. The yarn hanging pins on the warp yarns on the rudder surface are parallel to each other and at equal intervals to ensure that the warp yarns are evenly distributed after being hung. Specifically, the spacing of the yarn hanging pins can be adjusted according to the product parameters. The spacing of the yarn hanging pins does not need to be consistent with the reed spacing. For example, if the reed spacing is 2mm, the yarn hanging pins can be 10mm, that is, the warp yarns of 5 reeds are all hung on 1 yarn hanging pin.

[0052] Preferably, such as Figure 2 , 3 As shown in Figure 4, the conformal reed 6 includes a conformal reed body 61 and multiple reed blades 62 disposed on the conformal reed body 61. The reed blades 62 are used for weft insertion. The shape and size of the cross-section of the structure formed by the multiple reed blades 62 are the same as the shape and size of the cross-section of the rudder fabric product. Here, the cross-section refers to the surface perpendicular to the length direction of the rudder fabric, that is, the shape and size of the overall transverse projection surface of the reed blades 62 on the conformal reed body 61 are the same as the shape and size of the transverse projection surface of the rudder fabric product.

[0053] Preferably, the reeds 62 on the rudder surface of the rudder fabric on the conformal reed body 61 are parallel to each other and equally spaced; the reeds 62 on the leading edge of the rudder fabric on the conformal reed body 61 are arranged in a fan-shaped ring, and the inner arc length of the fan ring between adjacent reeds is equal. The reeds 62 of the conformal reed 6 are designed according to the outer dimensions and parameters of the leading edge of the rudder fabric and the rudder surface, and are used to achieve uniform warp distribution and weft density control, thereby ensuring that the outer dimensions of the rudder fabric meet the requirements. For example, the inner arc length of the leading edge of the rudder fabric is 21mm, the outer arc length is 64mm, the warp density of the rudder surface is 10 threads / cm, and the warp density of the leading edge is 10 threads / cm. Therefore, when designing the contour reed, the reed at the rudder position can be designed as No. 50, with a reed blade gap of 2mm and 2 rows of warp yarns per reed; the reed at the outer arc length of the leading edge can be designed as No. 25, with a reed blade gap of 4mm and 4 rows of warp yarns per reed, for a total of 16 reed blades. The inner arc length is divided into 16 equal parts, the reed blades at the leading edge are fan-shaped, the reed blade gaps on the inner arc are 1.31mm, and 3 rows of warp yarns per reed.

[0054] Preferably, the rudder fabric contour weaving device further includes a mandrel advance button, a mandrel retraction button, and an emergency stop button. The mandrel advance button is electrically connected to the forward and reverse motors and is used to control the forward rotation of the motors. The mandrel retraction button is electrically connected to the forward and reverse motors and is used to control the reverse rotation of the motors. The emergency stop button is electrically connected to the forward and reverse motors and is used to stop the forward and reverse motors. The advance button moves the contour mandrel forward to a suitable position, ensuring the internal dimensions of the rudder fabric during weft winding. The retraction button moves the contour mandrel backward to the previous weft weft position, allowing the contour reed to tighten the weft yarn to the weft position. The emergency stop button allows for manual control, ensuring safety in emergency situations.

[0055] Preferably, such as Figure 9As shown, the rudder fabric contour weaving device also includes a control module and an input module. The mandrel forward button, mandrel backward button, emergency stop button, input module, and forward / reverse motors are electrically connected to the control module. The control module controls the forward and reverse motors to rotate forward based on the signal from the mandrel forward button. The control module also controls the forward and reverse motors to rotate in reverse based on the signal from the mandrel backward button. The control module also controls the forward and reverse motors to stop running based on the signal from the emergency stop button. The control module also controls the forward and reverse motors to move the mandrel a certain distance based on the forward or backward distance signal input from the input module. The input module is used to input parameters for the forward and backward distances of the mandrel. Based on the parameters input from the input module, the control module edits instructions and sends them to the forward and reverse motors. The forward and reverse motors execute the instructions sent by the control module, driving the mandrel forward or backward a corresponding distance via the lead screw. Specifically, for example, if the weft density of the rudder fabric is 2 threads / cm, the input module is set to input a forward distance of 10mm and a backward distance of 5mm for the mandrel. When weft winding is required, the mandrel forward button is pressed. At this time, the control module, based on the parameters of the input module, edits the command to send the mandrel forward 10mm to the forward and reverse motors. The forward and reverse motors control the lead screw to rotate, causing the mandrel to move forward to the 10mm position. After the movement stops, weft winding can begin. After weft winding is completed, the reverse button is pressed. At this time, the control module, based on the parameters of the input module, edits the command to send the mandrel backward 5mm to the forward and reverse motors. The forward and reverse motors control the lead screw to rotate, causing the mandrel to move backward to the 5mm position. After the movement stops, the reed tightens the weft yarn to the weft end position, and then the weaving cycle continues.

[0056] Example 2

[0057] The rudder fabric contour weaving method of this embodiment utilizes the rudder fabric contour weaving device of Embodiment 1 for weaving, and includes the following steps:

[0058] S1. The warp yarns are fed onto the rudder fabric conformal weaving device according to the warp yarn arrangement parameters of the rudder fabric. One end of the warp yarn is hung on the conformal yarn hanging plate, and the other end passes through the conformal reed and is connected to the tension line of the warp feeding mechanism. The warp yarns are under tension.

[0059] S2. Press the core mold forward button. The forward and reverse motors rotate forward to move the core mold to the weft winding position. Then, manually wind the warp yarns layer by layer onto the core mold.

[0060] S3. After weft winding is completed, press the back button. The forward and reverse motors reverse and move the mandrel back to the weft winding position. Then, the linear guide rail drives the reed seat to move along the reed support, and the reed performs weft winding until the weft density is qualified.

[0061] S4. Repeat steps S2-S3 until the rudder fabric is woven.

[0062] In some embodiments, the fibers used in weaving can be high-performance fibers such as quartz fiber and carbon fiber. In this embodiment, 195tex quartz fiber is used as the raw material.

[0063] In some implementations, the rudder fabric is woven using a three-dimensional structure, which may be a 2.5D structure, a 2.5D weft-insertion structure, or an orthogonal three-dimensional structure. In this embodiment, a 2.5D structure is used.

[0064] The rudder fabric contour weaving method of this embodiment meets the requirements of rudder fabric contour weaving, improves the product quality and consistency of rudder fabric contour weaving, and reduces production costs. Due to the use of the rudder fabric contour weaving device, the contour reed can make the warp yarns at the front edge evenly arranged and the shape of the front edge consistent. Due to the use of the contour reed for straight weft insertion, there is no weft skew in the weft yarn arrangement, the weft yarns are evenly arranged along the thickness direction, the internal density is uniform, and the warp and weft density is uniform. Due to the appropriate tension of the warp yarns, the warp yarns are easy to weave in layers, the weaving efficiency is improved, and the weaving cost is reduced.

[0065] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
