Description

Technical Field

[0002] Aramid honeycomb is a composite core material made from aramid paper through a series of processes, including gluing, lamination, hot pressing, impregnation, and slicing. It is primarily used in high-end sectors such as rail transit, aerospace, shipbuilding, and military applications. Sandwich-structured composite components made from aramid honeycomb core material combined with prepreg not only achieve lightweighting requirements but also offer numerous advantages, including corrosion resistance, noise reduction, and vibration damping. Consequently, aramid honeycomb has found widespread application in rail transit and aerospace interiors.

[0003] Cutting the aramid paper honeycomb core material before CNC machining can greatly improve the efficiency of CNC machining. The cutting process is completed by a sawing machine, which saws the aramid paper honeycomb core material, thereby improving the efficiency of CNC machining. Most of the existing cutting tools are fixed tools, which have poor versatility, a wide variety of tool specifications, and are difficult to replace. Specifically, each tool has a fixed angle and can only cut aramid paper honeycomb core materials of one target specification. For aramid paper honeycomb core materials with different specifications, multiple tools must be assembled to meet the processing requirements of different target specifications. At the same time, the tool is fixed to the sawing machine with glue. When replacing tooling of different specifications, not only must the glue be removed, but the new tool must also be repositioned.

DETAILED DESCRIPTION

[0030] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0031] Example 1

[0032] See also Figures 1 to 10 The present utility model discloses a tooling device for blanking aramid paper honeycomb core material, designed to be used in conjunction with a sawing machine to process aramid paper honeycomb core material 20. As shown in the figure, a preferred embodiment thereof comprises a base plate 6, a fixing fixture 4, a thickness adjustment unit, an angle adjustment unit, and a horizontal inclination measurement unit.

[0033] The base plate 6 is located at the bottom of the entire device. The fixing clamp 4 fixes the base plate 6 to the sawing platform 17 of the sawing machine, thereby achieving the purpose of fixing the entire device on the sawing platform 17. The fixing clamp 14 is composed of a quick-release clamp and a clamp bolt 19. Among them, there are multiple quick-release clamps, which are fixed to the sawing platform 17 by the clamp bolts 19. Multiple quick-release clamps are arranged along the outer edge of the base plate 6 to form a layout that matches the size of the base plate 6. When the quick-release clamps are closed, they press the base plate 6 toward and fix it on the sawing platform 17. The thickness adjustment unit is installed on the base plate 6 and can translate relative to the base plate 6 to adapt to the thickness of different product honeycomb blocks 18. The angle adjustment unit is installed on the thickness adjustment unit and translates with the thickness adjustment unit. At the same time, it can rotate itself to adjust the bevel angle required for the product honeycomb block 18. To ensure that the horizontality and inclination of the angle adjustment unit meet the specifications of the honeycomb block 19, a horizontal and inclination angle measuring unit is magnetically mounted on the angle adjustment unit. This unit translates and rotates with the angle adjustment unit, providing real-time measurement of the horizontality and inclination of the angle adjustment unit. In this embodiment, the horizontal and inclination angle measuring unit is a torpedo-type digital level 1.

[0034] The thickness adjustment unit consists of the lower plate 5, a third support bar 15, a slider 7, a slide rail 8, and fixing bolts 14. The slide rail 8 and slider 7 form a sliding platform that drives the lower plate 5 to translate relative to the bottom plate 6. There are two sets of slide rails 8, arranged horizontally and fixed on both sides of the top surface of the bottom plate 6. Slide rails 7 are fixed on both sides of the bottom surface of the lower plate 5, and their number and position correspond one-to-one with the slide rails 8. Multiple sets of fixing bolts 14 are also provided on the lower plate 5, corresponding to the positions of the slide rails 8. The sliders 7 are embedded in the slide rails 8 and work with them, moving back and forth within the guide of the slide rails 8, thereby driving the lower plate 5 to translate relative to the bottom plate 6. It can be seen that the further the lower plate 5 is from the saw blade 16, the greater the thickness of the aramid paper honeycomb core material 20 after cutting. Therefore, by adjusting the position of the lower plate 5 relative to the saw blade 16, the thickness of the finished honeycomb block 18 can be adjusted. Once adjusted to the correct position, the fixing bolts 14 can be tightened, pressing the lower plate 5 against the slide rails 8. This increases the friction between the sliders 7 and the slide rails 8, preventing the sliders 7 from moving further and thus fixing the relative position of the lower plate 5 and the base plate 6. Below the lower plate 5, multiple third support bars 15 are fixed parallel to the slide rails 8, thereby strengthening the support strength of the lower plate 5 without affecting its sliding motion.

[0035] The angle adjustment unit is composed of a side panel 3, a back panel 2, a rear support panel 13, a first support bar 9, a second support bar 10, a limiting bolt 11 and a pin 12. Among them, the first support bar 9, the second support bar 10, the limiting bolt 11 and the pin 12 constitute a rotation limiting module, which is used to control the controllable rotation adjustment angle of the back panel 2. There are two groups of side panels 3, which are right-angled sectors and are fixed on both sides of the top surface of the lower panel 5. A pin 12 is installed at the center position of the side panel 3, and an arc-shaped limiting groove is set on the side panel 3. The rear support panel 13 is set at the position where the arc edge of the side panel 3 contacts the lower panel 5. The lower part of the rear support panel 13 is fixed to the rear part of the top surface of the lower panel 5, and its front is fixed to the arc part of the side panel 3.

[0036] The back panel 2 is located between the two side panels 3. Two blind holes are provided on each side edge of the back panel. The two blind holes correspond to pins 12 at the center of the two side panels 3. The pins 12 extend into the blind holes, allowing the back panel 2 to rotate about the center of the side panels 3, thereby adjusting the angle of the bevel of the honeycomb block 18. A first support bar 9 is fixed to each edge of the back panel. The two first support bars 9 are parallel to each other and fixed to the back panel 2. A second support bar 10 is provided between the two first support bars 9 and fixed to the back panel 2. The second support bar 10 connects the two first support bars 9 at right angles to them and serves to increase the strength of the back panel 2. A limit bolt 11 is provided on the first support bar 9. The position of the limit bolt 11 corresponds to the position of the limit slot on the side panel 3. After passing through the first support bar 9, the limit bolt 11 extends into the limit slot. In this way, the back panel 2 is rotatably connected to the side panel 3 with the center of the fan-shaped side panel 3 as the axis. During its rotation, the stop bolts 11 remain in their grooves. Once the desired angle is reached and the stop bolts 11 are tightened, the back plate 2 is pulled toward the side plates 3 on either side. The friction increases, securing it in place and maintaining the angle between the back plate 2 and the lower plate 5. As can be seen, the angle between the back plate 2 and the lower plate 5 corresponds to the inclination of the inclined surface of the honeycomb block 18.

[0037] The following briefly describes a processing method using a preferred embodiment of an aramid paper honeycomb core material blanking tooling device of the present invention, including the following steps:

[0038] Step S100: installing tooling.

[0039] According to the shape of the base plate, the quick-release clamp is placed on the sawing platform, and then the clamp bolts are used to connect and fix the quick-release clamp to the sawing platform. Next, the quick-release clamp is closed to fix the base plate to the sawing platform, thus connecting the aramid paper honeycomb core material blanking tooling to the sawing platform.

[0040] Step S200, adjusting the cutting thickness.

[0041] According to the thickness of the honeycomb block, the position of the lower plate and the bottom plate is adjusted using the thickness adjustment unit. After adjustment, it is locked with the fixing bolt to fix the relative distance between the lower plate and the saw blade.

[0042] Step S300: adjusting the cutting angle.

[0043] The angle between the backplate and saw blade is adjusted using the angle adjustment unit based on the bevel angle of the honeycomb block. During adjustment, a horizontal and inclination angle measurement unit (a torpedo-style digital level) magnetically attached to the backplate simultaneously reads both the horizontal and inclination readings. Once the adjustment is in place, tighten the stop bolts to secure the angle between the backplate and saw blade.

[0044] Step S400: loading the honeycomb core material.

[0045] Use double-sided tape to fix the aramid paper honeycomb core material on the back plate of the angle adjustment unit.

[0046] Step S500: cutting.

[0047] Start the sawing machine and the saw blade cuts the aramid paper honeycomb core material vertically, thereby forming a product honeycomb block with a preset width and preset angle to facilitate subsequent CNC processing.

[0048] Step S600: Determine whether to change the model.

[0049] When the model of the honeycomb block to be produced needs to be changed, that is, the thickness or angle of the honeycomb block is different from the previous cutting, the process jumps to step S200 to reset the tooling. Otherwise, the process jumps to step S400 to carry out the next cutting of the honeycomb block of the same model.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. In other words, any equivalent changes and modifications made within the scope of the patent application of the present invention should fall within the technical scope of the present invention.
