Description

Technical Field

[0001] This utility model belongs to the field of aramid honeycomb processing technology, and in particular relates to an aramid honeycomb structure stretching machine. Background Technology

[0002] Aramid honeycomb is a lightweight, high-strength honeycomb material made of aramid fibers. Its structure mimics the shape of a honeycomb in nature, with a hexagonal lattice arrangement. Aramid fibers themselves have excellent mechanical properties, high temperature resistance, and chemical stability. After these fibers are made into honeycomb core material through special processing technology, the material exhibits extremely high specific strength and specific stiffness while maintaining extremely low density.

[0003] In the processing of aramid honeycomb, the stretching process is a crucial step, directly affecting the structural integrity and performance of the final product. Because aramid honeycomb is a porous structure formed from extremely thin aramid fiber paper through processes such as impregnation, lamination, and hot pressing, it possesses a certain degree of brittleness, especially under uneven stress conditions. Traditional stretching processes typically use rigid clamps to hold and fix one end of the honeycomb before applying tensile force to expand it to the target size.

[0004] However, the lattice structure of aramid honeycomb is easily damaged in the clamping area due to concentrated clamping forces, especially when the clamping force is too large or unevenly distributed. This can cause the honeycomb walls to be crushed, torn, or even collapse locally. Such damage not only affects the appearance quality of the honeycomb core material but can also create stress concentration points within it, reducing overall mechanical properties. Furthermore, due to the lightweight nature of aramid honeycomb, its structure is more sensitive to clamping forces. Excessive clamping force can also cause non-uniform deformation of the honeycomb during stretching, such as localized overstretching or insufficient unfolding, thus affecting the subsequent bonding quality with the panel.

This machine facilitates the clamping and stretching of aramid honeycomb bodies of different thicknesses, ensures stable clamping of the aramid honeycomb bodies, and allows for the detection of clamping force to prevent excessive clamping force from causing damage.

[0006] In view of this, the present invention provides an aramid honeycomb structure stretching machine, comprising: The mounting post has a movable clamping mechanism and a static clamping mechanism at its front end. The movable clamping mechanism and the static clamping mechanism work together to position the aramid honeycomb body. A spring is positioned between the moving clamping mechanism and the stationary clamping mechanism; A pressure sensor is installed on the moving clamping mechanism or the stationary clamping mechanism. One end of the spring is attached to the sensing end of the pressure sensor to detect the clamping force of the moving clamping mechanism and the stationary clamping mechanism.

[0009] Furthermore, it also includes a positioning rod, a through groove one is opened at the upper end of the base plate, a through groove two is opened at the upper end of the clamping plate, and a honeycomb hole is opened at the upper end of the aramid honeycomb body.

[0010] Furthermore, the positioning rod is a screw rod, the bottom end of the positioning rod passes through the nut and is threadedly connected to the nut, and the upper end of the nut is in contact with the lower end of the base plate.

[0022] Please see Figures 1 to 7 This utility model provides an aramid honeycomb structure stretching machine, comprising: Mounting column 4, with a dynamic clamping mechanism and a static clamping mechanism at the front end of mounting column 4. The dynamic clamping mechanism and the static clamping mechanism work together to position the aramid honeycomb body 1. Spring 23 is disposed between the moving clamping mechanism and the stationary clamping mechanism; A pressure sensor 24 is installed on the moving clamping mechanism or the stationary clamping mechanism. One end of the spring 23 is attached to the sensing end of the pressure sensor 24 to detect the clamping force of the moving clamping mechanism and the stationary clamping mechanism.

[0023] In the example of this application, the precise positioning of the aramid honeycomb body 1 is achieved through the coordinated action of the moving clamping mechanism and the stationary clamping mechanism located at the front end of the mounting column 4. This fixes the aramid honeycomb body 1, ensuring that the honeycomb structure does not experience unnecessary displacement during the stretching process, thus guaranteeing the stability of the entire stretching operation. The spring 23, located between the moving and stationary clamping mechanisms, effectively mitigates the impact of the clamping force when clamping the aramid honeycomb body 1, preventing damage to the structure of the aramid honeycomb body 1 due to rigid clamping, thus providing protection. The pressure sensor 24, installed on the moving or stationary clamping mechanism, has its sensing end in contact with one end of the spring 23, allowing the pressure sensor 24 to capture changes in the force transmitted by the spring 23 in real time, thereby detecting the magnitude of the clamping force exerted by the moving and stationary clamping mechanisms on the aramid honeycomb body 1. By observing the data fed back by the pressure sensor 24, the operator can accurately control the clamping force. This can prevent the aramid honeycomb body 1 from shifting during the stretching process due to excessively loose clamping, thus affecting the stretching effect. It can also avoid damaging the structure of the aramid honeycomb body 1 due to excessively tight clamping, thereby improving the reliability and safety of the stretching operation.

[0024] Furthermore, the moving clamping mechanism includes a lifting drive mechanism. A moving block 8 is installed at the drive end of the lifting drive mechanism. A connecting frame 18 is fixed at the front end of the moving block 8. A connecting plate 13 is inserted into the connecting frame 18. A clamping plate 3 is fixed at the front end of the connecting plate 13. The connecting plate 13 and the connecting frame 18 are connected by bolts 17.

[0025] As a preferred example of this utility model, the lifting drive mechanism can move the movable block 8. The connecting frame 18, which is fixedly connected to the front end of the movable block 8, is connected to the connecting plate 13 inserted therein. The clamping plate 3 is fixed to the front end of the connecting plate 13. When the lifting drive mechanism is in operation, it can drive the clamping plate 3 to lift and lower through the transmission of the movable block 8, the connecting frame 18, and the connecting plate 13. The lifting function allows the clamping plate 3 to flexibly adjust its clamping position according to the specific size and position requirements of the aramid honeycomb body 1, ensuring that the aramid honeycomb body 1 can be clamped from a suitable angle and position. At the same time, the connection between the connecting plate 13 and the connecting frame 18 through bolt 17 facilitates the disassembly and replacement of the clamping plate 3. When it is necessary to process aramid honeycomb bodies 1 of different specifications, the operator can easily remove bolt 17 to replace the clamping plate 3 of the corresponding size, or perform maintenance on the clamping plate 3, which enhances the equipment's versatility for different workpieces and improves the equipment's maintenance convenience.

[0026] Furthermore, the lifting drive mechanism includes a long groove 6 opened at the front end of the mounting column 4, a movable block 8 slidably disposed in the long groove 6, a motor 5 installed at the upper end of the mounting column 4, a threaded rod 7 connected to the drive end of the motor 5, and the threaded rod 7 passes through the movable block 8 and is threadedly connected to the movable block 8.

[0027] As a preferred example of this utility model, the elongated groove 6 at the front end of the mounting column 4 provides a stable sliding track for the movable block 8, allowing it to slide smoothly within the groove 6. The motor 5, mounted on the upper end of the mounting column 4, serves as the power source, with its drive end connected to a threaded rod 7. The threaded rod 7 passes through the movable block 8 and is threadedly connected to it. When the motor 5 starts, it drives the threaded rod 7 to rotate, causing the movable block 8 to move up and down along the elongated groove 6 under the action of the thread. This structure, where the motor 5 drives the threaded rod 7 to rotate, thereby causing the movable block 8 to slide, enables the clamping plate 3 to rise and fall, ensuring the accuracy of the clamping position. The threaded drive itself has self-locking properties; when the motor 5 stops, the movable block 8 remains stationary on the threaded rod 7, preventing movement due to slight external forces. This allows the clamping plate 3 to remain stably in any position, ensuring the stability of the clamping of the aramid honeycomb body 1 and improving the accuracy and reliability of the equipment operation.

[0028] Furthermore, the static clamping mechanism includes a connecting frame 15 fixed below the mounting column 4, a connecting frame 2 18 located above the connecting frame 15, a connecting plate 2 14 inserted into the connecting frame 15, a base plate 2 fixed at the front end of the connecting plate 2 14, and the connecting plate 2 14 and the connecting frame 15 connected by bolts 16.

[0029] As a preferred example of this utility model, the connecting bracket 15 fixed below the mounting column 4 is located below the connecting bracket 2 18. A connecting plate 2 14 is inserted into the connecting bracket 15, and the base plate 2 is fixed to the front end of the connecting plate 2 14. The connecting plate 2 14 and the connecting bracket 15 are connected by bolts 16. This facilitates the disassembly and replacement of the base plate 2. When dealing with aramid honeycomb bodies 1 of different sizes, the operator can replace the base plate 2 with different specifications to cooperate with the clamping plate 3 of the moving clamping mechanism, forming a clamping space that better fits the size of the aramid honeycomb body 1. This improves the equipment's adaptability to workpieces of different specifications, allowing the equipment to meet more diverse work needs and enhancing its practicality.

[0030] Furthermore, it also includes a positioning rod 9, a through groove 11 at the upper end of the base plate 2, a through groove 2 12 at the upper end of the clamping plate 3, and a honeycomb hole at the upper end of the aramid honeycomb body 1. The positioning rod 9 moves through the through groove 11, the through groove 2 12 and the honeycomb hole to position the aramid honeycomb body 1.

[0031] As a preferred example of this utility model, the through slot 11 at the upper end of the base plate 2, the through slot 12 at the upper end of the clamping plate 3, and the honeycomb holes at the upper end of the aramid honeycomb body 1 together constitute the through path of the positioning rod 9. The positioning rod 9 moves through these three parts, constraining the aramid honeycomb body 1. During the stretching process, positioning can effectively prevent the aramid honeycomb body 1 from shifting or rotating, ensuring that the aramid honeycomb body 1 is stretched along the preset direction, thus guaranteeing the accuracy of the stretching direction. At the same time, accurate positioning also provides strong support for the stretching operation, allowing the stretched aramid honeycomb structure to meet the preset size and performance requirements, thereby improving the overall quality of the stretching operation.

[0032] Furthermore, the positioning rod 9 is a screw rod, with the bottom end of the positioning rod 9 passing through the nut 10 and being threadedly connected to the nut 10. The upper end of the nut 10 is in contact with the lower end of the base plate 2.

[0033] As a preferred example of this utility model, the bottom end of the positioning rod 9 passes through the nut 10 and is threadedly connected to the nut 10. When the height of the positioning rod 9 needs to be adjusted, the operator only needs to rotate the nut 10. Under the action of the thread, the positioning rod 9 will move up and down, thereby adapting to aramid honeycomb bodies 1 of different thicknesses. The positioning rod 9 can be positioned for aramid honeycomb bodies 1 of various specifications, enhancing the flexibility of positioning. In addition, the upper end of the nut 10 fits against the lower end of the base plate 2, which can fix the positioning rod 9. During the stretching process, the nut 10 can lock the position of the positioning rod 9, preventing it from loosening, ensuring the stability of the positioning effect, and ensuring that the aramid honeycomb body 1 is always in the correct position during the stretching process.

[0034] Furthermore, connecting brackets 319 are fixed on both sides of the rear end of clamping plate 3, connecting plate 321 is inserted into connecting brackets 319, and connecting brackets 319 and connecting plate 321 are connected by bolts 320.

[0035] As a preferred example of this utility model, the connection method between the connecting frame 3 19 and the connecting plate 3 21 allows for easy position adjustment and disassembly of the connecting plate 3 21. Operators can change the position of the connecting plate 3 21 within the connecting frame 3 19 by loosening or tightening bolts 3 20, thereby changing the position of the mounting plate 1 22, which is fixedly connected to the rear end of the connecting plate 3 21. Changing the position of the mounting plate 1 22 affects the initial state of the spring 23 fixed at its lower end, allowing the spring 23 to better cooperate in the detection and buffering of clamping force.

[0036] Furthermore, connecting brackets 4 28 are fixed on both sides of the rear end of the base plate 2, connecting plates 4 26 are inserted into the connecting brackets 4 28, and the connecting brackets 4 28 and the connecting plates 4 26 are connected by bolts 4 27.

[0037] As a preferred example of this utility model, the connection method between the connecting frame 4 28 and the connecting plate 4 26 facilitates the adjustment and disassembly of the connecting plate 4 26. By adjusting the position of the connecting plate 4 26 within the connecting frame 4 28, the position of the mounting plate 2 25, which is fixedly connected to the rear end of the connecting plate 4 26, can be changed. The pressure sensor 24 is mounted on the upper end of the mounting plate 2 25. Ensuring that the pressure sensor 24 maintains a good contact with the spring 23 fixed to the lower end of the mounting plate 22 allows the pressure sensor 24 to accurately detect changes in the clamping force transmitted by the spring 23, ensuring the reliability of the detection data and providing precise information for operators to adjust the clamping force.

[0038] Furthermore, the rear end of the connecting plate 3 21 is fixed to the mounting plate 1 22, the lower end of the mounting plate 1 22 is fixed to the spring 23, the rear end of the connecting plate 4 26 is fixed to the mounting plate 2 25, and the upper end of the mounting plate 2 25 is installed with a pressure sensor 24.

[0039] As a preferred example of this utility model, when the moving clamping mechanism and the stationary clamping mechanism clamp the aramid honeycomb body 1, the clamping force is transmitted to the spring 23, causing the spring 23 to deform and its elastic force to change accordingly. The pressure sensor 24 can detect the change in elastic force and convert it into an electrical signal to feed back to the operator. The operator can understand the magnitude of the clamping force between the moving clamping mechanism and the stationary clamping mechanism in real time and accurately. The operator can adjust the clamping force in a timely manner to ensure that the clamping force is within a suitable range, neither too loose to affect the stretching effect nor too tight to damage the aramid honeycomb body 1, thereby ensuring that the stretching operation can be carried out smoothly.

[0040] Furthermore, the widths of the through slot 11, through slot 2, and honeycomb holes are adapted.

[0041] As a preferred example of this utility model, the positioning rod 9, when passing through these three parts, can fit tightly against the inner walls of each part with almost no gaps. This reduces the wobbling of the positioning rod 9 during the stretching process, ensures positioning accuracy, allows the aramid honeycomb body 1 to be stably positioned in the preset position, and avoids various problems caused by size mismatch. The width adaptability ensures the smooth operation of the positioning mechanism, while also effectively protecting the aramid honeycomb structure.

[0042] In this embodiment, when it is necessary to clamp and fix the aramid honeycomb body 1, one end of the aramid honeycomb body 1 is carefully inserted between the base plate 2 and the clamping plate 3. At this time, all components of the entire device are ready to work, and the mounting column 4, as the core support component, has its front-end structure ready to respond to operation commands at any time. The motor 5, installed on the upper end of the mounting column 4, is started. The drive end of the motor 5 then drives the threaded rod 7 to rotate. Since the threaded rod 7 passes through and is threadedly connected to the moving block 8, and the rotational freedom of the moving block 8 is limited by the long groove 6 at the front end of the mounting column 4, the moving block 8 will move smoothly downward along the trajectory of the long groove 6. The connecting bracket 18 fixed at the front end of the moving block 8 also moves downward synchronously. The connecting plate 13 inside the connecting bracket 18, connected by bolt 17, drives the clamping plate 3 at the front end to move downward together. As clamping plate 3 moves downward, connecting brackets 3 and 19 fixed on both sides of its rear end also move downward. Connecting plate 3 and 21, connected by bolts 3 and 20 inside connecting bracket 3 and 19, drive mounting plate 1 and 22 at the rear end to move downward synchronously. Spring 23 fixed at the lower end of mounting plate 1 and 22 moves downward. As clamping plate 3 gets closer to base plate 2, the bottom end of spring 23 gradually approaches pressure sensor 24 mounted on the upper end of mounting plate 2 and 25. When the bottom end of spring 23 contacts the upper end of pressure sensor 24, pressure sensor 24 immediately begins to detect the clamping force in real time. As clamping plate 3 continues to move downwards, the gap between base plate 2 and clamping plate 3 gradually decreases, eventually clamping and confining the aramid honeycomb body 1 located between them. The operator monitors the changes in clamping force in real time using pressure sensor 24, and flexibly adjusts the operating state of motor 5 based on the detected values, thereby controlling the downward speed and final position of clamping plate 3, effectively preventing structural damage to the aramid honeycomb body 1 due to excessive clamping force. The connecting brackets 28 fixed to both sides of the rear end of base plate 2, and the connecting plate 26 internally connected by bolts 27, provide stable support for mounting plate 25 and pressure sensor 24 during clamping, ensuring the accuracy of pressure detection is not affected by external interference.

[0043] After the base plate 2 and clamping plate 3 firmly clamp the aramid honeycomb body 1, the operator aligns the positioning rod 9 with the second through slot 12 at the upper end of the clamping plate 3, and then passes it through the clamping plate 3, the honeycomb holes of the aramid honeycomb body 1, and the first through slot 11 at the upper end of the base plate 2 in sequence. Since the first through slot 11 and the second through slot 12 are aligned vertically, the positioning rod 9 can smoothly pass through each structure without jamming or shifting. Finally, the bottom end of the positioning rod 9 is threaded through the nut 10, and the nut 10 is tightened to ensure its upper end fits tightly against the lower end of the base plate 2, thus forming the clamping plate 3, the aramid honeycomb body 1, and the base plate 2 into a single unit. This achieves the effect of facilitating the clamping and stretching of aramid honeycomb bodies 1 of different thicknesses, ensuring stable clamping of the aramid honeycomb body 1, and allowing for the detection of clamping force to prevent damage caused by excessive clamping force.
