Description

Technical Field

[0001] This invention relates to the field of composite panel technology, and more specifically, to a processing technology for a honeycomb composite panel and a precision carving device used in this process. Background Technology

[0002] A honeycomb composite panel consists of two face panels and a honeycomb interlayer filling them. In the current honeycomb composite panel manufacturing process, a complete honeycomb panel is usually placed between the two face panels and hot-pressed.

[0003] In actual production and processing, the thickness of different parts of the surface of the panels used in different scenarios varies, requiring irregular shaping. Therefore, after the surface panel and honeycomb panel are pressed, the thickness of different parts of the honeycomb panel is not uniform, resulting in different rebound forces after crushing. Ultimately, this affects the overall stability of the final composite panel. Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Summary of the Invention

S3. Preparation of composite material board: The honeycomb board carved in S2 is taken out of the precision carving machine, and fiber material is wrapped on both sides of the board.

[0006] By adopting the above technical solution, the thickness of each part of the honeycomb panel is engraved to correspond to the thickness of each part of the composite board.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively. Specific Implementation

[0024] A composite material honeycomb skeleton processing technology includes the following steps: S1. Honeycomb material preparation: According to the composite material to be processed, cut the honeycomb skeleton material into honeycomb panels of the required shape, thickness and size; S2, honeycomb panel engraving: Place the honeycomb panel cut in S1 into the engraving machine, and engrave the surface of the honeycomb panel according to the shape, thickness and size of the final composite material product. S3. Preparation of composite material board: The honeycomb board carved in S2 is taken out of the precision carving machine, and fiber material is wrapped on both sides of the board. The honeycomb composite material board is made by spraying glue on the front and back sides, foaming the material, pressing the mold, heat bonding and cooling.

[0025] By carving the surface of the honeycomb panel, the thickness of each part of its surface corresponds to the thickness of each part of the composite board. This ensures that the thickness of each part of the honeycomb panel is consistent after it is compressed into the composite board, which facilitates subsequent processing of the composite board and ensures the overall structural stability of the final honeycomb composite board. Specific Implementation

[0026] As shown in the figure, a precision engraving device for the above-mentioned processing technology includes a precision engraving machine body and a dust removal component. The precision engraving machine body includes a base 1 and a precision engraving component 2 slidably connected to the surface of the base 1. The precision engraving component 2 includes a three-axis machining base 3, on which a drive motor 4 is mounted. The output shaft of the drive motor 4 is vertically downward and has a precision engraving cutter head 5 mounted thereon. Several vertically mounted fixing plates 6 are mounted on the surface of the base 1. The two ends of the fixing plates 6 are fixedly connected to the two ends of the base 1. Several positioning pins 7 are evenly arranged along the length of the surface of the fixing plates 6. Support plates 35 are mounted at both ends of the three-axis machining base 3. Two pressure rollers 36 located at the same horizontal height are rotatably connected between the two support plates 35, so that the precision engraving cutter head 5 is located between the two pressure rollers 36.

[0027] The honeycomb panel to be engraved is placed on the engraving machine body, and the data is input into the three-axis machining base 3 according to the overall shape of the composite honeycomb panel to be processed, so as to control the motor 4 to drive the engraving cutter head 5 to engrave the surface of the honeycomb panel. As the three-axis machining base 3 moves along the base 1, the pressure roller 36 rolls and presses against the surface of the honeycomb panel to ensure the stability of the honeycomb panel during the engraving process, and the waste chips generated are collected and processed by the dust removal component.

[0028] A first movable plate 8 is provided on one side of each fixed plate 6 on the surface of the base 1. Several inclined pins 9 are evenly arranged on the top of the first movable plate 8 along its length. A first limiting groove 10 parallel to the direction of the pins 9 is formed on the surface of the first movable plate 8. Several limiting rods 11 are provided on both sides of the fixed plate 6, with one limiting rod 11 sliding within the first limiting groove 10. A first driving assembly is also included to drive the first movable plate 8 to move along the inclined angle direction of the first limiting groove 10. After the honeycomb panel is placed on the surface of the base 1, it is pressed down so that the pins 9 are inserted into the bottom of the honeycomb panel to ensure its stability. The first driving assembly then moves the first movable plate 8 upward along the first limiting groove 10, allowing the pins 9 to be inserted into the bottom of the honeycomb panel, further improving the stability of the honeycomb panel during the engraving process.

[0029] Each first movable plate 8 has a first connecting plate 12 at one end, and a first insert block 13 at one end of the first connecting plate 12. The surface of the first connecting plate 12 has several first slots for the first insert blocks 13 to be inserted. A horizontally mounted mounting plate 14 is fixedly connected to one side wall of the base 1. The first driving assembly includes a first rotating plate 15 rotatably connected to the surface of the mounting plate 14. Both ends of the first rotating plate 15 have first pull plates 16. The bottom of the first pull plate 16 has a slot for the first rotating plate 15 to be inserted. The other end of the first pull plate 16 is hinged to one of the first movable plates 8. The mounting plate 14 also has a first cylinder 17 for driving the first rotating plate 15. The first cylinder 17 drives the first rotating plate 15 to rotate, and under the action of the first pull plate 16, it causes the first movable plate 8 to rise or fall along the first limiting groove 10, thereby controlling the insertion of the pin 9 into or out of the honeycomb panel.

[0030] A second movable plate 18 is provided on the other side surface of the fixed plate 6. The surface of the second movable plate 18 is provided with a plurality of second limiting grooves 19 parallel to the first limiting groove 10. The limiting rod 11 on the other side of the fixed plate 6 slides in the second limiting groove 19. It also includes a second driving component for driving the second movable plate 18 to move along the tilt angle direction of the second limiting groove 19.

[0031] Each second movable plate 18 has a second connecting plate 20 at one end and a second insert block 21 at one end. The surface of the second connecting plate 20 has several second slots for the second insert block 21 to be inserted. The second drive assembly includes a second rotating plate 22 rotatably connected to the surface of the mounting plate 14. The two ends of the second rotating plate 22 are respectively provided with second pull plates 23. The bottom of the second pull plate 23 is provided with a slot for the second rotating plate 22 to be inserted. The other end of the second pull plate 23 is hinged to one of the second movable plates 18. The mounting plate 14 is also provided with a second cylinder 24 for driving the second rotating plate 22.

[0032] After the honeycomb panel is engraved, the first drive assembly drives the first movable plate 8 to move downward along the first limiting groove 10, so that the pin 9 is pulled out from the honeycomb panel. At the same time, the second cylinder 24 drives the second rotation, and under the action of the second pull plate 23, it drives the second movable plate 18 to rise, so that the top of the second movable plate 18 abuts against the surface of the honeycomb panel and lifts the honeycomb panel upward, so that the honeycomb panel is separated from the positioning pin 7, so that the honeycomb panel can be removed from the base 1.

[0033] Two sets of the first movable plate 8, the first drive assembly, the second movable plate 18, and the second drive assembly are provided. The two sets of first and second drive assemblies are located at both ends of the base 1, forming two processing stations on the surface of the base 1. Two waste collection covers 25 are provided at the bottom of the base 1, each corresponding to one of the two processing stations. The bottom of each waste collection cover 25 has a first through hole 26 connected to a dust collection assembly. While engraving is being performed at one station, the other station can perform loading or unloading operations, improving processing efficiency.

[0034] The output shaft end of the drive motor 4 is provided with a dust collection housing 27. The bottom of the dust collection housing 27 is provided with a through groove for the engraving head 5 to pass through. A brush 28 is provided along the periphery of the through groove at the bottom of the dust collection housing 27. The surface of the dust collection housing 27 is provided with a second through hole 29 connected to the dust collection assembly.

[0035] The dust collection assembly includes a cyclone dust collector 30, a bag filter dust collector 31, and a casting fan 32. The cyclone dust collector 30 is connected to a first air guide duct 33, which is equipped with an explosion-proof valve 37 to improve the safety performance of the device. One end of the first air guide duct 33 is connected to a T-connector 34, one end of which is connected to a flexible hose (not shown in the figure) and connected to a first through hole 26. The other end of the T-connector 34 is connected to a second through hole 29 via another flexible hose (not shown in the figure). Under the action of the dust collection assembly, the waste generated during the engraving of the precision engraving head 5 is recovered through the second through hole 29, and some waste falls from the surface of the base 1 into the waste collection hood 25 and is recovered through the first through hole 26.

[0036] The top of the dust collector bag is equipped with a spray port 38, a thermometer 39, a pressure sensor 40, and an explosion vent 41. The spray port helps to reduce dust, the thermometer 39 can detect the internal temperature in real time, and the pressure sensor 40 and the explosion vent 41 can release pressure to ensure the internal pressure and production safety.

[0037] The feed rate of the precision engraving cutter head 5 is 10000-12000mm / min, and the rotation speed is 20000-25000r / min, to ensure the engraving effect on the honeycomb panel.

[0038] The specific embodiments are merely illustrative of the present invention and are not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
