Description

Technical Field

[0001] This utility model relates to the field of laser cutting equipment technology, and in particular to a high-efficiency square and rectangular tube laser cutting machine. Background Technology

[0002] A laser cutting machine uses a laser emitted from a laser source, which is focused into a high-power-density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting or boiling point. At the same time, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a kerf is eventually formed in the material, thus achieving the purpose of cutting.

[0003] Existing laser cutting machines cannot quickly position rectangular tubes before cutting pipes, wasting cutting time and resulting in low cutting efficiency. Furthermore, the rectangular tubes usually need to be manually handled after cutting, which is very inconvenient. Utility Model Content

A rectangular tube concentrator is installed above the conveying mechanism. A U-shaped frame is installed on the cutting table. A vertically downward infrared meter is installed on the top end of the U-shaped frame near the conveying mechanism. A first hydraulic cylinder is installed on the U-shaped frame. The piston end of the first hydraulic cylinder passes through the U-shaped frame and is connected to a pressure plate. A laser cutting head is provided on one side of the pressure plate. The laser cutting head is connected to the top and bottom surfaces of the U-shaped frame through a horizontal adjustment assembly. A lifting hole is opened on the table surface of the cutting table on one side of the U-shaped frame. A drive roller is provided in the lifting hole.

[0008] Furthermore, the support plate is connected to the conveying mechanism via a support rod.

[0009] Furthermore, the conveying mechanism includes a conveying frame and a plurality of conveying rollers mounted on the conveying frame. The conveying rollers are driven by a conveying motor mounted on the conveying frame, and the support rod is connected to the conveying frame.

[0010] Furthermore, an anti-slip layer is attached to the bottom surface of the pressure plate.

[0011] Furthermore, the lateral adjustment assembly includes a second hydraulic cylinder installed on one side of the U-shaped frame. The piston end of the second hydraulic cylinder passes through the U-shaped frame and is connected to the laser cutting head. A slider is connected to the top of the laser cutting head, and the slider is slidably connected to a slide rail provided on the top and bottom surface of the U-shaped frame.

[0012] Furthermore, the drive assembly includes a drive motor mounted on the lifting plate, and pulleys are connected to both the output end of the drive motor and the end of the drive roller, with the two pulleys connected by a belt.

[0013] Furthermore, the lifting assembly includes a mounting plate connected to the cutting table, a third hydraulic cylinder connected to the mounting plate, the piston end of the third hydraulic cylinder connected to the bottom surface of the lifting plate, and two guide rods connected to the mounting plate, the top ends of the guide rods passing through guide holes opened in the lifting plate and then connected to the cutting table.

[0014] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0015] This invention can transport the cut square and rectangular tubes away by a drive roller, eliminating the need for manual handling, saving a lot of manpower, greatly improving work efficiency, and can also concentrate the tubes in the middle position through the square and rectangular tube concentration component, making it easier to fix them before cutting.

[0025] A U-shaped frame 3 is installed on the cutting table 2, and a vertically downward infrared meter 4 is installed on the top end of the U-shaped frame 3 near the conveying mechanism 1.

[0026] A first hydraulic cylinder 5 is installed on the U-shaped frame 3. The piston end of the first hydraulic cylinder 5 passes through the U-shaped frame 3 and is connected to a pressure plate 6. An anti-slip layer is connected to the bottom surface of the pressure plate 6.

[0027] A laser cutting head 7 is provided on one side of the pressure plate 6. The laser cutting head 7 is connected to the top and bottom surfaces of the U-shaped frame 3 through a lateral adjustment assembly. The lateral adjustment assembly includes a second hydraulic cylinder 18 installed on one side of the U-shaped frame 3. The piston end of the second hydraulic cylinder 18 passes through the U-shaped frame 3 and is connected to the laser cutting head 7. A slider 19 is connected to the top of the laser cutting head 7. The slider 19 is slidably connected to a slide rail 20 provided on the top and bottom surfaces of the U-shaped frame 3.

[0028] A lifting hole 8 is provided on the table surface of the cutting table 2 on one side of the U-shaped frame 3. A drive roller 9 is provided in the lifting hole 8. The two ends of the drive roller 9 are mounted on the lifting plate 11 through bearing brackets 10. The drive roller 9 is driven by a drive assembly mounted on the lifting plate 11. The drive assembly includes a drive motor mounted on the lifting plate 11. Both the output end of the drive motor 21 and the end of the drive roller 9 are connected to pulleys 22.

Then tighten the locking nut 16. When the rectangular tube is sent to the cutting table 2, the infrared meter counter 4 records the length of the conveyed tube. When the set length is reached, the first hydraulic cylinder 5 descends and presses the rectangular tube onto the cutting table 2, and the conveying motor on the conveying mechanism 1 stops working. Then the second hydraulic cylinder 18 cuts the rectangular tube with the laser cutting head 7. After the cutting is completed, the first hydraulic cylinder 5 resets, and at the same time the third hydraulic cylinder 25 drives the driving roller 9 to rise, so that the driving roller 9 presses against the rectangular tube after the cutting. Then the drive motor 21 works, so that the driving roller 9 moves and sends the rectangular tube away. Then the conveying motor on the conveying mechanism 1 works to continue to send the rectangular tube, and then the above actions are repeated.
