Description

Technical Field

[0001] This utility model relates to the field of aluminum foam processing technology, and more specifically, it relates to a laser cutting device for aluminum foam. Background Technology

[0002] As a lightweight and high-strength new material, aluminum foam is increasingly widely used in aerospace, rail transportation, building decoration and other fields. Laser cutting, as a high-energy beam processing technology, has the characteristics of avoiding mechanical stress, reducing material deformation and tool wear, processing complex shapes, high precision, no dust pollution and high degree of automation.

[0003] Currently available laser cutting equipment for sheet metal cannot effectively polish the edges of the material being cut during the cutting process. This means that after the laser cutting machine completes its cutting work, users will find that the edges of the cut material are rough and have not undergone any form of finishing or smoothing. This may affect the appearance and quality of the final product. At the same time, the transmission device of the laser cutting device usually uses a roller screw pair. However, during daily use, when dust and other impurities fall onto the screw, it affects the performance and service life of the transmission device. Utility Model Content

[0016] Compared with the prior art, this utility model provides a laser cutting device for aluminum foam, which has the following advantages:

[0017] 1. By setting a drive motor to drive the first gear and the second gear to rotate, the fixed ring rotates on the fixed frame. The fixed ring drives the grinding block to rotate, and after the laser cutting is completed, the cutting edge is ground, which improves the cutting effect of the foam aluminum. By setting a vacuum cleaner and a dust cover, it is easy to absorb the dust and impurities generated during grinding and prevent the worktable from being contaminated.

[0018] 2. The drive motor drives the drive screw to rotate. The position and height of the cutter are adjusted by the cooperation of the drive screw and the drive nut.

The transmission screw 12 is provided with a transmission nut 13 and a ball bearing 14. A cleaning sleeve 15 is threadedly connected to the transmission nut 13. A cleaning groove 16 is provided on the cleaning sleeve 15. A telescopic rod 17 is provided on the cleaning groove 16. A cleaning brush 18 is provided at one end of the telescopic rod 17. A vacuum cleaner 19 is also provided on the fixed frame 5. A vacuum cleaner 19 is provided with a vacuum cover 20. A rotating ring 21 is provided on the fixed frame 5. A rotating groove 22 is provided on the fixed ring 6. A cleaning plate 23 is provided on the movable end of the telescopic rod 17. A cleaning spring 24 is provided between the cleaning plate 23 and the cleaning groove 16.

[0030] In this embodiment, when laser cutting aluminum foam, the aluminum foam is fixed by the existing operating table 2 fixing device. The position of the cutter 4 is adjusted by the transmission device. After cutting, the height of the cutter 4 is adjusted, and the cutter 4 drives the fixing frame 5 to move, so that the grinding block 7 is attached to the aluminum foam. Then, the drive motor 8 is started, and the drive motor 8 drives the first gear 9 and the second gear 10 to rotate. The second gear 10 drives the fixing ring 6 and the grinding block 7 to rotate. By rotating the grinding block 7, the edge of the laser cut is ground to improve the cutting effect. At the same time, the dust generated by the dust collector 19 and the dust collection hood 20 are started to absorb the dust and prevent the dust from contaminating the operating table 2.

[0031] Please see Figures 3-5 As one embodiment of lubrication of the ball bearing 14: the transmission nut 13 is provided with an oil injection groove 25, and a lubrication groove 26 is connected to the oil injection groove 25. The lubrication groove 26 is connected to the ball bearing 14. An oil injection hole 27 is provided on one side of the oil injection groove 25, and a plug 28 is provided on the oil injection hole 27. A piston rod 29 is slidably provided on the oil injection groove 25. A handle 30 is provided at one end of the piston rod 29, and a piston plate 31 is provided at the other end. An oil injection spring 32 is provided between the piston plate 31 and the oil injection groove 25. A wiping cotton 33 is provided inside the cleaning sleeve 15.

[0032] More specifically, the cleaning sleeve 15 is installed by thread, and the cleaning plate 23 is squeezed by the cleaning spring 24. This causes the movable end of the telescopic rod 17 and the cleaning brush 18 to squeeze the transmission screw 12. When the transmission screw 12 rotates, the cleaning brush 18 cleans the surface of the transmission screw 12, and the wiping cotton 33 is also used for cleaning. At the same time, the plug 28 is opened, and the handle 30 is pulled upward. The handle 30 drives the piston rod 29 and piston plate 31 to move, compressing the oil injection spring 32 and injecting lubricating oil into the lubrication groove 26 and into the lubrication hole. After the plug 28 is plugged, the oil injection spring 32 gives the piston plate 31 elastic force, so that the lubricating oil is injected into the lubrication groove 26 and flows into the ball bearing 14, lubricating the ball bearing 14 and the transmission screw 12, thus improving the smoothness of movement between the transmission screw 12 and the transmission nut 13.

[0033] In summary, during the use or operation of the overall equipment: when laser cutting aluminum foam, the aluminum foam is fixed by the existing operating table 2 fixing device. The position of the cutter 4 is adjusted by the transmission device. After cutting, the height of the cutter 4 is adjusted, and the cutter 4 drives the fixing frame 5 to move, so that the grinding block 7 is attached to the aluminum foam. Then, the drive motor 8 is started, and the drive motor 8 drives the first gear 9 and the second gear 10 to rotate. The second gear 10 drives the fixing ring 6 and the grinding block 7 to rotate. By rotating the grinding block 7, the edge of the laser cut is ground to improve the cutting effect. At the same time, the dust generated by the dust collector 19 and the dust collection hood 20 are activated to absorb the dust and prevent the dust from contaminating the operating table 2.

[0034] The cleaning sleeve 15 is installed by thread, and the cleaning plate 23 is squeezed by the cleaning spring 24. This causes the movable end of the telescopic rod 17 and the cleaning brush 18 to squeeze the transmission screw 12. When the transmission screw 12 rotates, the cleaning brush 18 cleans the surface of the transmission screw 12 and the wiping cotton 33 cleans it. At the same time, the plug 28 is opened and the handle 30 is pulled upward. The handle 30 drives the piston rod 29 and piston plate 31 to move, compressing the oil injection spring 32 and injecting lubricating oil into the lubrication groove 26 and into the lubrication hole. After the plug 28 is plugged, the oil injection spring 32 gives the piston plate 31 elastic force, so that the lubricating oil is injected into the lubrication groove 26 and flows into the ball bearing 14, lubricating the ball bearing 14 and the transmission screw 12, improving the smoothness of movement between the transmission screw 12 and the transmission nut 13.
