AI Technical Summary

Technical Problem

Existing technologies have problems in the hot pressing process of honeycomb panels, such as local pressure concentration caused by contact between rigid molds and honeycomb panel surfaces, and poor mold fit in areas of curvature abrupt change. This leads to the crushing of the honeycomb core, panel dents, and delamination of the adhesive layer. Vacuum bag pressing cannot compensate for the pressure in local high curvature areas, resulting in insufficient pressure at the top of the curved surface and panel wrinkles.

Method used

The system employs a flexible film and flexible pressure block array structure, combined with negative pressure adsorption and traction structures. The flexible pressure blocks adhere tightly to the surface of the honeycomb panel through negative pressure adsorption, and the interlocking of the flexible pressure blocks creates continuous pressure. The traction structure dynamically adjusts the pressure direction to ensure seamless adhesion and uniform distribution of positive pressure on the surface of the honeycomb panel.

Benefits of technology

It achieves seamless bonding of honeycomb panels and uniform distribution of positive pressure, avoiding problems such as crushing of honeycomb panels and delamination of adhesive layers, and ensuring efficient shaping and appearance quality of irregularly shaped honeycomb panels.

Description

Technical Field

[0001] This invention relates to the field of irregular honeycomb panel shaping technology, and more specifically, to a shaping device for processing irregular honeycomb panels. Background Technology

[0002] Honeycomb composite materials are widely used in aerospace, rail transportation, shipbuilding, and modern building decoration due to their high specific strength, high specific stiffness, and excellent sound and heat insulation properties. As product design develops towards lightweighting, curved surfaces, and functional integration, irregularly shaped honeycomb panels, including single-curved surfaces, double-curved surfaces, variable curvature surfaces, and honeycomb components with flanged structures, are gradually becoming the mainstream form of structural components.

[0003] In existing technologies, curved honeycomb components are often formed by hot pressing with rigid molds. This involves heating and pressurizing the honeycomb core and panel together using upper and lower metal or composite material molds. However, this method suffers from surface contact between the rigid mold and the honeycomb panel, leading to localized pressure concentration in irregular curved areas, causing the honeycomb core to crush or the panel to dent. Furthermore, areas with abrupt curvature changes often experience gaps due to improper mold fit, resulting in adhesive layer detachment. Another forming method is vacuum bag pressing. This approach places the honeycomb panel on a single-sided mold, covers it with a vacuum bag film, and applies atmospheric pressure for shaping after vacuuming. While the vacuum bag film can only provide a uniform load, it cannot compensate for pressure in areas with high curvature, resulting in insufficient pressure at the top of the curved surface and excessive pressure at the bottom. Simultaneously, the vacuum bag film is prone to wrinkling during stretching, and these wrinkles are imprinted on the panel surface, causing not only aesthetic defects but also potential misalignment of the two components to be glued. Summary of the Invention

[0004] The purpose of this invention is to provide a shaping device for processing irregularly shaped honeycomb panels, which addresses the shortcomings of existing technologies and solves the problems mentioned in the background.

[0005] The technical solution of this invention is implemented as follows:

[0006] The invention provides a shaping device for processing irregular honeycomb panels, including a processing platform, a negative pressure adsorption port installed on the worktable of the processing platform, and a negative pressure device connected to the negative pressure adsorption port inside the processing platform; A flexible film is laid on the workbench to cover the negative pressure adsorption port; Several flexible pressure blocks are provided on the side wall opposite to the worktable surface of the flexible film. The flexible pressure blocks are arranged in an array on the inner side wall of the flexible film, and any two adjacent flexible pressure blocks interlock with each other. The flexible pressure blocks are equipped with fixed structures on their side walls facing the worktable, and the two fixed structures located on any two adjacent flexible pressure blocks are flexibly connected. The worktable is equipped with a traction structure for pulling the flexible pressure block to move onto the worktable.

[0007] In some technical solutions of the present invention, the flexible pressure block includes an annular mounting frame, and the outer side wall of the mounting frame is surrounded by airbags connected end to end. One side of the airbag is provided with a groove, and the other side of the airbag is provided with a protrusion. The groove on the airbag in one of the flexible pressure blocks and the protrusion on the airbag in the adjacent flexible pressure block are in concave-convex fit, and the fixed structure is installed on the outer side wall of the airbag.

[0008] In some technical solutions of the present invention, a protective plate is installed on the workbench, and an array of heating wires is installed between the workbench and the protective plate. A temperature control structure electrically connected to the heating wires is provided inside the work platform.

[0009] In some technical solutions of the present invention, the shaping structure includes a plurality of shaping strips installed along the length direction of the flexible pressure block, and the shaping strips are partially embedded in the outer side wall of the airbag.

[0010] In some technical solutions of the present invention, an assembly groove is provided on the side wall of the shaping strip away from the airbag, a limiting strip is slidably provided in the assembly groove, a portion of the limiting strip protrudes outward from the assembly groove, and a reset spring connected to the limiting strip is provided in the assembly groove.

[0011] In some technical solutions of the present invention, the traction structure includes two frames installed in the worktable, each frame having several mounting seats corresponding to the flexible pressure blocks, each mounting seat having a winch rotatably mounted on it, and each mounting seat having a limiting structure for restricting the rotation of the winch; the winch has a drive structure connected to the winch drive, a traction rope is threaded through the annular channel of the mounting frame, and the two ends of the traction rope are respectively wound around the two winches; the frame has an adjustment structure for pushing the two mounting seats connected to the same traction rope to reciprocate synchronously.

[0012] In some technical solutions of the present invention, the adjustment structure includes a shaft installed in the frame, mounting seats all sleeved on the outer side wall of the shaft, a spiral groove opened on the outer side wall of the shaft, a rotating seat rotatably mounted on the mounting seat, a ball embedded in the groove rotatably mounted on the inner side wall of the rotating seat, a first helical gear mounted on the outer side wall of the rotating seat, a guide structure for guiding the mounting seat to move in the horizontal direction provided in the frame, a displacement seat slidably mounted in the frame along its extension direction, a mounting groove opened on the side wall of the displacement seat, a first drive motor slidably mounted in the mounting groove, a second helical gear meshing with the first helical gear on the output end of the first drive motor, and an electromagnetic push rod connected to the drive motor mounted in the mounting groove.

[0013] In some technical solutions of the present invention, a lead screw is installed inside the frame, and a ball transmission sleeve that is fixedly connected to the displacement seat is rotatably provided on the lead screw.

[0016] Compared with the prior art, the present invention has at least the following advantages or beneficial effects: a negative pressure adsorption port is set on the workbench and a flexible film is laid on it. The vacuum is created by using a negative pressure device to make the film tightly adhere to the workbench to form a rigid equivalent plane. At the same time, the film completely fills the gap between the bottom surface of the honeycomb panel and the workbench. The flexible film also applies downward pressure to the array of flexible pressure blocks. The flexible pressure blocks themselves have deformable capabilities. Adjacent flexible pressure blocks form an interlocking structure to continuously apply positive pressure to the irregular area, transforming discrete point pressure into continuous contour-following pressure, eliminating pressure gaps and stress concentration points. Furthermore, the pressure blocks are pulled towards the workbench by a traction structure. The force direction of the traction structure can be changed according to the position of the pressure block on the irregular curved surface, thereby dynamically adjusting the pressure on the irregular curved surface so that the force direction of the pressure block on the board surface is as close as possible to the normal direction of the curved surface, preventing the two irregular curved surface structures that are glued together from being directly attached and misaligned.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0030] Example This invention provides a shaping device for processing irregularly shaped honeycomb panels, such as... Figure 1 , Figure 2 As shown, the device includes a processing platform 1, which serves as the mounting base for the entire apparatus. A plurality of negative pressure adsorption ports 102 are evenly distributed on the worktable surface 101 of the platform, arranged in an array. A negative pressure device 103 (such as a negative pressure pump) connected to the negative pressure adsorption ports 102 is also fixedly installed inside the processing platform 1. Once activated, the negative pressure device 103 generates a stable negative pressure suction force through the negative pressure adsorption ports 102. A protective plate 104 is also laid on the workbench 101. Between the workbench 101 and the protective plate 104, an array of heating wires 105 are installed. The processing platform 1 is equipped with a temperature control structure 106 (such as a temperature controller or temperature sensor) that is electrically connected to the heating wires 105. The temperature control structure 106 can monitor the temperature of the heating wires 105 in real time and make precise adjustments to ensure that the heating temperature meets the shaping requirements. The protective plate 104 is made of a high-temperature resistant and thermally conductive material (such as a ceramic plate or a transparent glass plate) to prevent the heating wires 105 from directly contacting the plate and causing damage, and to prevent the plate from carbonizing or being damaged due to excessively high temperature, or from being incompletely shaped due to excessively low temperature.

[0031] It also includes a flexible film 2 and flexible pressure blocks 3, which are used to cover irregularly shaped workpieces and form a flexible bonding structure. First, the flexible film 2 completely covers the protective plate 104 of the worktable 101, and at the same time covers all the negative pressure adsorption ports 102, which plays a role in sealing and buffering. Then, the flexible film 2 is fixed to the processing platform 1 by a frame structure to prevent gas leakage. Several flexible pressure blocks 3 are also set between the flexible film 2 and the protective plate 104. The flexible pressure blocks 3 are arranged in an array, and any two adjacent flexible pressure blocks 3 interlock with each other to ensure that there are no gaps when the combined flexible pressure blocks 3 are bonded to the curved surface of the irregularly shaped workpiece.

[0032] The two interlocking flexible pressure blocks 3 ensure that the pressure block array becomes a continuous pressure surface on a macroscopic level, avoiding the generation of pressure gaps; while "independent traction" does not refer to completely independent pressure control, but rather to the ability to fine-tune the tightness of the pressure block's fit to the curved surface and the normal pressure by adjusting the tension of the traction rope at different positions, thereby achieving "optimization of pressure distribution" rather than complete "independent control".

[0033] The flexible pressure block 3 specifically includes a ring-shaped mounting frame 301. An airbag 302 (made of highly elastic, high-temperature resistant rubber) is fixedly attached end-to-end around the outer wall of the mounting frame 301. One side of the airbag 302 has a groove 303, and the other side has a protrusion 304 that matches the groove 303. The airbags 302 of adjacent flexible pressure blocks 3 achieve a convex-concave fit through the groove 303 and the protrusion 304. The two convex-concave airbags 302 are rotatably connected by a pin to prevent separation and to make the engagement of adjacent flexible pressure blocks 3 tighter and more secure. The airbag 302 has good elastic deformation capability and can adaptively deform according to the surface contour of the irregular honeycomb panel, while providing buffer support for the subsequent shaping structure 4. The flexible film 2 plays a sealing and buffering role, ensuring the sealing of the negative pressure adsorption while avoiding damage to the panel from rigid contact, achieving comprehensive adaptation to various irregular irregular contours.

[0034] Preferably, the air bladder inside the flexible block can be configured as protrusions at both ends, or as grooves at both ends.

[0035] The shaping structure 4 is installed on the outer wall of the airbag 302 of the flexible pressure block 3. The shaping structures 4 located on two adjacent flexible pressure blocks 3 are connected by flexible connectors (such as flexible metal sheets or hinges) to ensure that the adjacent shaping structures 4 can still maintain continuous fit when the flexible pressure block 3 is deformed.

[0036] The shaping structure 4 specifically includes several shaping strips 401 (made of metal with moderate rigidity) arranged along the length of the flexible pressure block 3. The shaping strips 401 are partially embedded in the outer wall of the airbag 302, which ensures the connection between the shaping strips 401 and the airbag 302 without affecting the elastic deformation of the airbag 302.

[0037] Preferably, an assembly groove 402 is provided on the side wall of the shaping strip 401 opposite to the airbag 302. A limiting strip 403 is slidably disposed in the assembly groove 402. A portion of the limiting strip 403 protrudes outward from the assembly groove 402. A return spring 404 is also provided inside the assembly groove 402 and fixedly connected to the limiting strip 403. The return spring 404 provides a continuous preload to the limiting strip 403, keeping the limiting strip 403 in a protruding state in its natural state, which can adapt to the slight concave and convex contours of the plate surface. Preferably, the assembly groove 402 is arranged along the width direction of the airbag 302. In this way, when positive pressure is applied to two irregularly shaped combined plates that are attached to each other through the above structure, the limiting strips 403 located on both sides of the airbag 302 that are not in contact with the irregularly shaped combined plates will restrict the irregularly shaped combined plates in this area, preventing the two parts of the irregularly shaped combined plates from misaligning under the coverage of the flexible film 2 when positive pressure is applied to the irregularly shaped combined plates, which would lead to the scrapping of parts after the irregularly shaped combined plates are shaped.

[0038] The structure also includes a traction structure 5 for moving the flexible pressure block 3 toward the irregular workpiece, ensuring that the shaping structure 4 fits tightly against the surface of the plate. The specific structure includes a frame 501, a mounting base 504, a winch 505, a drive structure 510, an adjustment structure 520, and a limiting structure 512.

[0039] There are two frames 501, which are symmetrically installed on both sides of the worktable 101. An electric push rod structure for adjusting the relative distance between the frames 501 is also installed within the worktable 101. Both ends of the frames 501 are mounted on slide rails within the worktable 101. When positioning irregularly shaped workpieces, the workpieces are located within the area enclosed by the two frames 501 within the worktable 101, and are secured to the worktable 101 by a mounting platform. Each frame 501 has several mounting seats 504 corresponding one-to-one with the flexible pressure blocks 3. A winch 505 is rotatably mounted on each mounting seat 504, and a drive structure 510 connected to the winch 505 is installed within the winch 505. The drive structure 510 includes a transmission gear 511 fixedly mounted on the outside of the winch 505. The transmission gear 511 meshes with a second helical gear 518, which is fixedly mounted on the output end of a first drive motor 517. The first drive motor 517 drives the second helical gear 518 and the transmission gear 511 to rotate, thereby driving the winch 505 to rotate. Each flexible block 3 corresponds to an independent winch 505 and a traction rope 525, enabling independent traction control of a single flexible block 3. The traction force and movement position of a single flexible block 3 can be adjusted according to the contour requirements of different parts of the sheet metal.

[0040] The traction structure pulls the flexible pressure block 3 by means of traction rope 525. Its direction of movement is "towards the worktable", but specifically it moves towards the two side frames, thereby pulling the pressure block towards the table.

[0041] A traction rope 525 (made of high-strength, wear-resistant steel wire rope) is threaded through the annular channel of the mounting frame 301. Preferably, the middle part of the traction rope 525 is fixed in the annular channel of the mounting frame 301, or a limiting block for locking the traction rope 525 is provided in the annular channel of the mounting frame 301. The two ends of the traction rope 525 are respectively wound around the winches 505 corresponding to the two frames 501. When the winches 505 rotate, the traction or release of the flexible pressure block 3 can be achieved by winding or releasing the traction rope 525. The mounting base 504 is also provided with a limiting structure 512 for limiting the rotation of the transmission gear. The limiting structure 512 includes a pawl 513 fixedly mounted on the mounting base 504. The outer side wall of the transmission gear is provided with a number of locking grooves 506. The pawl 513 cooperates with the locking grooves 506. The mounting base 504 is also provided with a tension spring 514 connected to the pawl 513. The tension spring 514 provides a preload force to the pawl 513, so that the pawl 513 always tends to be embedded in the locking grooves 506.

[0042] The adjustment structure 520 is used to drive the two mounting seats 504 connected to the same traction rope 525 to reciprocate synchronously, adjusting the position of the winch 505 and the traction rope 525 so that they are aligned with the force direction of the flexible pressure block 3. The adjustment structure 520 includes a shaft 502 fixedly installed in the frame 501, and mounting seats 504 are all sleeved on the outer wall of the shaft 502. The outer wall of the shaft 502 has a spiral groove 503. A rotating seat 507 is rotatably installed on the mounting seat 504. A ball 508 embedded in the spiral groove 503 is rotatably installed on the inner wall of the rotating seat 507. A first helical gear 509 is fixedly installed on the outer wall of the rotating seat 507. The frame 501 also has a guide structure 521 (such as a guide groove or guide block) for guiding the mounting seats 504 to move in the horizontal direction. The adjustment structure 520, through the cooperation of the spiral groove 503 and the ball 508, converts the rotational motion into the horizontal linear motion of the mounting base 504. With the meshing transmission of the helical gear, it realizes the precise position adjustment of the mounting base 504, so that the traction force direction of the traction rope 525 is consistent with the movement direction of the flexible pressure block 3, avoiding the waste of traction force and the displacement of the pressure block.

[0043] A displacement seat 515 is slidably disposed inside the frame 501 along its extension direction. An installation groove 516 is provided on the side wall of the displacement seat 515. A first drive motor 517 is slidably disposed in the installation groove 516. A second helical gear 518 is provided at the output end of the first drive motor 517 and meshes with the first helical gear 509. An electromagnetic push rod 519 connected to the first drive motor 517 is also installed in the installation groove 516. The electromagnetic push rod 519 can push the first drive motor 517 to slide, so as to realize the meshing and disengagement of the second helical gear 518 and the first helical gear 509. In addition, a lead screw 522 is installed inside the frame 501. A ball transmission sleeve 523, which is fixedly connected to the displacement seat 515, is rotatably mounted on the lead screw 522. A second drive motor, which is connected to the lead screw 522, is fixedly installed inside the frame 501. After the second drive motor is started, it can drive the lead screw 522 to rotate, thereby driving the ball transmission sleeve 523 and the displacement seat 515 to slide along the frame 501 to adapt to the mounting seat 504 in different positions.

[0044] The specific steps for the shaping process of this device are as follows, applicable to the shaping of various irregularly shaped honeycomb panels (especially panels with complex outlines and prone to breakage): Preliminary preparation: Place the irregularly shaped honeycomb panel to be shaped on the protective plate 104 of the workbench 101, and place the workbench on the protective plate 104 to raise the horizontal height of the irregularly shaped honeycomb panel structure. Adjust the position of the panel to ensure that the area of ​​the panel to be shaped covers the array range of the flexible pressure block 3. Preset the heating temperature through the temperature control structure 106. According to the softening temperature of the panel material (such as plastic honeycomb panel, composite honeycomb panel), set the temperature controller to 50-150℃ to ensure that the plasticity of the panel reaches the best or the adhesive for bonding the two parts hardens after heating.

[0045] Positioning and Traction Preparation: Start the second drive motor, which drives the lead screw 522 to rotate. The ball transmission sleeve 523 drives the displacement seat 515 to slide along the frame 501, adjusting the first drive motor 517 to the position corresponding to the mounting seat 504 to be traction. Start the electromagnetic push rod 519, which pushes the first drive motor 517 to slide, causing the second helical gear 518 to mesh with the first helical gear 509 on the rotating seat 507. Start the first drive motor 517. The second helical gear 518, the first helical gear 509, and the rotating seat 507 are rotated. The ball 508 on the inner side of the rotating seat 507 slides along the spiral groove 503 of the shaft 502, causing the mounting seat 504 to move horizontally along the shaft 502. This adjusts the position of the winch 505 so that the traction rope 525 and the flexible pressure block 3 are aligned in the direction of force. After adjustment, the electromagnetic push rod 519 pulls the first drive motor 517 to reset, the second helical gear 518 separates from the first helical gear 509, and the mounting seat 504 remains fixed. For irregularly shaped plates with extreme curvature changes (such as S-shaped or spherical surfaces), the angle of the traction rope changes greatly. This precision adjustment system ensures that the pressure always acts perpendicularly on the pressure block and prevents lateral forces from causing displacement of the pressure block or damage to the honeycomb panel.

[0046] Heating and softening: The temperature control structure 106 is activated, and the heating wire 105 is energized and heats up. The heat is evenly transferred to the irregular honeycomb board through the protection plate 104. The temperature control structure 106 monitors the temperature in real time through the temperature sensor to ensure that the temperature is stable within the preset range. The board gradually softens under the action of heat, improving its plasticity and making it easier for subsequent shaping.

[0047] Flexible bonding and negative pressure compaction: The first drive motor 517 of the traction structure 5 is activated, which drives the second helical gear 518 and the transmission gear 511 to rotate, thereby driving the winch 505 to rotate. The winch 505 winds the traction rope 525, which generates a stable traction force, pulling the flexible pressing block 3 towards the protective plate 104. The airbag 302 of the flexible pressing block 3 adapts to the contour of the plate surface. Adjacent airbags 302 are tightly engaged through the groove 303 and the protrusion 304 to avoid gaps. At the same time, the negative pressure device 103 is activated, which generates negative pressure suction through the negative pressure adsorption port 102. Under the action of negative pressure, the flexible film 2 adheres tightly to the protective plate 104, further driving the flexible pressing block 3 and the shaping structure 4 to be firmly pressed onto the surface of the irregular honeycomb plate.

[0048] Refined Shaping: The shaping strip 401 adheres to the surface of the sheet material along with the airbag 302. The limiting strip 403 on the shaping strip 401 is tightly attached to the surface of the sheet material under the pre-tightening force of the return spring 404. For the protruding parts 304 of the sheet material, the limiting strip 403 is squeezed and slides inward along the assembly groove 402. The return spring 404 is compressed and generates a reverse elastic force, so that the limiting strip 403 fits tightly against the protruding parts 304. For the concave parts of the sheet material, the return spring 404 pushes the limiting strip 403 out of the assembly groove 402 and embeds it into the concave part, realizing the refined shaping of the fine contours of the sheet material. Adjacent shaping strips 401 are connected by flexible connectors to maintain continuous fit and ensure that there are no dead corners on the shaping surface.

[0049] Shaping and Cooling: When the shaping structure 4 is fully in contact with the surface of the board and the preset shaping pressure is reached, the tension spring 514 pulls the pawl 513 into the locking groove 506 of the winch 505, restricting the rotation of the winch 505, so that the traction rope 525 maintains a stable traction force, while keeping the negative pressure device 103 and the heating wire 105 working to maintain the shaping state for a period of time (set to 5-15 minutes according to the thickness of the board); then, turn off the heating wire 105 and the temperature control structure 106, maintain the negative pressure and traction state, and wait for the board to cool to room temperature (or the preset cooling temperature) to ensure that the shaped shape is stable, then turn off the negative pressure device 103.

[0050] Reset and Material Retrieval: Manually pull the pawl 513 to overcome the elastic force of the tension spring 514, causing the pawl 513 to disengage from the locking groove 506 and release the restriction on the winch 505; start the first drive motor 517 to rotate in the opposite direction, driving the winch 505 to rotate in the opposite direction, releasing the traction rope 525, and the flexible pressure block 3 is reset under the elastic reset action of the airbag 302, and the groove 303 and protrusion 304 of the adjacent airbag 302 are separated; then, the adjusting structure 520 drives the mounting base 504 and the winch 505 back to the initial position, and the operator takes out the shaped honeycomb panel, completing one shaping operation, and the device can enter the next round of operation.

[0051] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
