Description

Technical Field

[0001] This invention belongs to the field of hydrogen cylinder processing technology, specifically a laser cutting device and cutting method for processing metal hydrogen cylinders. Background Technology

[0002] Metal hydrogen cylinders are high-pressure containers used for storing and transporting hydrogen. They are typically made of high-strength alloy materials to ensure safe and reliable storage of hydrogen under high pressure conditions. These containers are widely used in industry, medicine, laboratories, and emerging hydrogen economy sectors, such as fuel cell vehicles. Laser cutting equipment for processing metal hydrogen cylinders is a device specifically designed for precise and efficient cutting of metal hydrogen cylinders. This equipment combines advanced laser technology and an automated control system to meet the requirements of high precision and safety.

[0003] A Chinese invention patent with publication number CN119703419A discloses a laser cutting device for producing liquefied petroleum gas (LPG) cylinders. The key technical points are: it includes two conveyor plates; a first cutting gun is fixedly connected to one side of the first pressing plate; a second cutting gun is slidably arranged on one side of the connecting frame; the first and second cutting guns are used to cut the first cylinder body; a transmission device is provided on one side of the fixed box to drive the drive wheel to rotate; and a collection box is provided on one side of the two conveyor plates. This invention uses a conveyor belt to transfer the first cylinder body, and the drive wheel can rotate the first cylinder body to perform laser cutting. The debris and waste generated after cutting the first cylinder body can be conveyed to one side by the conveyor belt and transmission rollers, thus simplifying the cutting process of LPG cylinders. After the first cylinder body is conveyed to the processing area, it can be processed directly without transfer, and the debris and waste generated after cutting can be directly recycled, thus accelerating the efficiency of laser cutting of LPG cylinders.

[0004] However, the above technologies often have the following drawbacks: Currently, traditional cutting methods are mainly blade cutting or laser cutting, both of which generate a lot of heat during the cutting process. For hydrogen cylinders that need to be processed, if there is residual hydrogen inside that has not been cleaned, the high temperature during external cutting may cause combustion or even explosion, posing a serious safety hazard. In addition, the lack of cooling function will cause the temperature of the cutting area to rise sharply, causing the surrounding material to overheat and forming a large heat-affected zone (HAZ). This not only affects the quality of the cut edge, but may also cause changes in material hardness or cracks, thereby reducing the structural strength and performance of the product.

The cooling and explosion-proof mechanism includes a mounting plate 3. The side of the mounting plate 3 is fixedly connected to the interior of groove A on one side of the processing machine tool 1. A drive motor A 4 is fixedly connected to the upper surface of the mounting plate 3. The output end of the drive motor A 4 is connected to a turntable 5 via a rotating rod spline. A connecting block 6 is rotatably connected to the edge of the outer surface of the turntable 5 via a rotating shaft A. Both ends of the connecting block 6 are fixedly connected to rotating components A 7. One end of the rotating component A 7 is fixedly connected to a rocker arm 8. One end of the rocker arm 8 is fixedly connected to a rotating component B 9. One end of the rotating component B 9 is fixedly connected to a support plate 10. One side of the support plate 10 is rotatably connected to a swing plate 11 via a rotating shaft B. A spray head 12 is fixedly connected to the outer surface of the oscillating plate 11. An air outlet 13 is opened on the outer surface of the oscillating plate 11 near the spray head 12. Through the cooling and explosion-proof mechanism, a large amount of heat is generated during the laser cutting process of hydrogen cylinder cutting and concentrated in the cutting area. The cooling mechanism can quickly remove this heat to prevent local overheating and reduce the risk of combustion or explosion of residual gas in the hydrogen cylinder. Appropriate cooling measures help to reduce the heat-affected zone of the material caused by high temperature. Rapid cooling can effectively avoid workpiece deformation caused by local overheating, ensure smoother and more precise cutting edges, and improve the quality of the final product.

[0023] Example 2: A water inlet pipe 14 is fixedly connected to the upper surface of the swing plate 11, and an air outlet pipe 15 is fixedly connected to the side of the frame plate 10. One end of the air outlet pipe 15 is fixedly connected to a blower A 16. The outer surface of the blower A 16 is fixedly connected to the bottom of the mounting plate 3. When the blower A 16 is started, the blower A 16 exhausts air from the air outlet hole 13 on the swing plate 11 through the air outlet pipe 15, thereby achieving a rapid cooling effect on the surface of the hydrogen cylinder.

[0024] The cutting mechanism includes an L-shaped frame plate 17, one side of which is fixedly connected to the front of the machine tool 1. A B drive motor 18 is fixedly connected to the surface of the L-shaped frame plate 17. The output end of the B drive motor 18 is connected to an A fixed block 20 via a splined support rod 19. There are two sets of A fixed blocks 20. The surface of one set of A fixed blocks 20 is rotatably connected to an A rotating rod 21 via a C rotating shaft. The surface of the other set of A fixed blocks 20 is rotatably connected to a B rotating rod 22 via a D rotating shaft. With the laser cutting head 2 and the cutting mechanism working together, when cutting hydrogen cylinders, different metal materials have different physical properties such as hardness, thickness, and heat resistance. The cutting method can be adjusted as needed to achieve the alternating use of the laser cutting head 2 and the cutting blade 27. When the two are used together, high-quality finished products can be obtained while ensuring the cutting speed.

[0025] One end of rotating rod A 21 is rotatably connected to support plate 23 via rotating shaft E. One end of rotating rod B 22 is rotatably connected to bevel gear A 24 via rotating shaft F. The outer surface of bevel gear A 24 meshes with bevel gear B 25. The outer surface of bevel gear B 25 is fixedly mounted with cutting blade 27 via rotating connecting rod 26. The inner side wall of support plate 23 is fixedly connected to plug rod 28. The outer surface of plug rod 28 is sleeved with fixing block B 29. Rotating rod B 22 drives bevel gear A 24 and bevel gear B 25 to mesh and rotate. Bevel gear B 25 drives rotating connecting rod 26 and cutting blade 27 to rotate. When support rod 19 rotates, the other end rotates on fixing block A 20 via rotating rod A 21, thereby achieving the effect of rotating and cutting with cutting blade 27.

[0026] A movable plate 30 is fixedly connected to the side of fixed block 29 B. A slide plate 31 is slidably connected to the outer surface of movable plate 30. The bottom of slide plate 31 is fixedly connected to one side of the upper surface of machine tool 1 through a pad. A slide rod 32 is slidably connected to the upper surface of movable plate 30. Both ends of slide rod 32 are fixedly connected to the inner side wall of machine tool 1. When fixed block 29 B rotates, it drives movable plate 30 to move in slide plate 31. Slide rod 32 plays a limiting and assisting role.

[0027] The transmission limiting mechanism includes a servo motor 33. The outer surface of the servo motor 33 is fixedly connected to the back of the machine tool 1. The output end of the servo motor 33 is splinedly connected to a threaded rod 34. The outer surface of the threaded rod 34 is threadedly connected to a threaded sleeve 35. The upper surface of the threaded sleeve 35 is fixedly connected to a conveyor plate 36. Slider blocks 37 are fixedly connected to both sides of the bottom of the conveyor plate 36. A moving rod 38 is rotatably connected to the middle of the upper surface of the conveyor plate 36 via a rotating rod A. One end of the moving rod 38 is rotatably connected to a pushing rod 39 via a rotating rod B. The other end of the moving rod 38 is rotatably connected to an electric push rod 40 via a rotating rod C. The clamping plate 43 clamps the hydrogen cylinder according to its size. The vacuum adsorption clamping method can reduce damage to the surface of the hydrogen cylinder while tightly adsorbing it, enhance the clamping firmness, and prevent errors caused by vibration or movement during the cutting process, thereby improving the quality of the finished product. The stable and uniform pressure distribution helps to avoid material deformation caused by local stress concentration.

[0028] The upper surface of the moving rod 38, near the C rotating rod, is rotatably connected to the B pushing rod 41 via the D rotating rod. The upper surfaces of both the A pushing rod 39 and the B pushing rod 41 are fixedly connected to the pushing plate 42. The two sides of the bottom of the pushing plate 42 are slidably connected to the upper surface of the conveying plate 36 via slide bars. The inner side wall of the pushing plate 42 is fixedly connected to the clamping plate 43. The electric push rod 40 is activated according to the size of the hydrogen cylinder. When the electric push rod 40 extends or retracts, it causes the moving rod 38 to swing. The position of the moving rod 38 tilts and rotates. When it rotates, it causes the A pushing rod 39 and the B pushing rod 41 to rotate and adjust. When the A pushing rod 39 and the B pushing rod 41 rotate, they can simultaneously drive the pushing plate 42 to move, clamping the pushing plate 42 inward.

[0029] The inner wall of the clamping plate 43 has a slot, and a suction cup 44 is fixedly installed inside the slot. An A transmission pipe 45 is fixedly connected to the outer surface of the clamping plate 43. One end of the A transmission pipe 45 is fixedly connected to a vacuum pump 46. The outer surface of the vacuum pump 46 is fixedly installed on one side of the outer surface of the conveying plate 36. The clamping plate 43 is in close contact with the surface of the hydrogen cylinder, so that the suction cup 44 is attached to the surface of the hydrogen cylinder. When the vacuum pump 46 is started, air is drawn into the suction cup 44 through the A transmission pipe 45, so that the clamping plate 43 and the hydrogen cylinder achieve a vacuum adsorption effect.

[0030] A placement plate 47 is fixedly connected to the upper surface of the moving rod 38. A B transmission pipe 48 is fixedly connected to the outer surface of the placement plate 47. A B blower 49 is fixedly connected to one end of the B transmission pipe 48. The outer surface of the B blower 49 is fixedly installed on the other side of the outer surface of the conveying plate 36. An air outlet 50 is opened on the upper surface of the placement plate 47. During the cutting process, the bottom of the hydrogen cylinder is blown by the B blower 49 into the B transmission pipe 48 and sprayed out from the air outlet 50 to dissipate heat and cool the area around the bottom of the hydrogen cylinder.

[0031] Example 3: This invention also discloses a method for using a laser cutting device for processing metal hydrogen cylinders. The method employs the aforementioned laser cutting device for processing metal hydrogen cylinders and includes the following steps: S1. When it is necessary to process and cut the hydrogen cylinder, according to the size of the hydrogen cylinder, use A push rod 39 and B push rod 41 to vacuum squeeze and clamp it, and then use the threaded rod 34 to drive the conveyor plate 36 to transport the hydrogen cylinder to the bottom of the laser cutting head 2. S2. Select the cutting method according to the specific material and model of the hydrogen cylinder. Alternatively, the laser cutting head 2 and the cutting blade 27 can be used together to cut the hydrogen cylinder. S3. While cutting, the swing plate 11 drives the spray head 12 to swing left and right, and then the blower A 16 and the air outlet pipe 15 blow air, spraying and blowing air at the same time to cool the outside of the hydrogen cylinder and remove the heat during cutting.

[0032] Working principle: Place the hydrogen cylinder to be processed on the placement plate 47. Start the electric push rod 40 according to the size of the hydrogen cylinder. When the electric push rod 40 extends or retracts, it drives the moving rod 38 to swing, causing the moving rod 38 to tilt and rotate. This rotation drives the A pushing rod 39 and B pushing rod 41 to rotate and adjust. The A pushing rod 39 and B pushing rod 41 simultaneously move the pushing plate 42, clamping it inwards. During clamping, the clamping plate 43 is pressed tightly against the surface of the hydrogen cylinder, causing the suction cup 44 to adhere to the surface of the hydrogen cylinder. Start the vacuum pump 46 to evacuate air from the suction cup 44 through the A transmission pipe 45, causing the suction cup to... The holding plate 43 achieves a vacuum adsorption effect with the hydrogen cylinder. After the hydrogen cylinder is clamped, the servo motor 33 is started. The servo motor 33 drives the threaded rod 34 to rotate, and the threaded rod 34 drives the threaded sleeve 35 and the conveyor plate 36 to move. The conveyor plate 36 pushes the hydrogen cylinder under the laser cutting head 2. The cutting method is selected as needed, either using the laser cutting head 2 or the cutting blade 27. If the cutting blade 27 is used, the B drive motor 18 is started. When the B drive motor 18 rotates, it drives the support rod 19 and the B rotating rod 22 to rotate. The B rotating rod 22 drives the A bevel gear 24 and the B... The bevel gear 25 meshes and rotates, driving the rotating connecting rod 26 and the cutting blade 27 to rotate. When the support rod 19 rotates, its other end rotates on the fixed block 20 via the rotating rod 21, thus achieving the effect of rotating and cutting the cutting blade 27. Subsequently, during the cutting process, the bottom of the hydrogen cylinder is blown through the transmission pipe 48 by the blower 49 and sprayed out from the outlet 50 to cool the area around the bottom of the hydrogen cylinder. Then, the water inlet pipe 14 is connected to an external water source, water is stored in the swing plate 11, and sprayed evenly from the spray head 12. The drive motor 4 is started to drive the turntable 5 to rotate, and the turntable 5 and the connecting rod 26 rotate together. Connecting block 6 is a centrifugal connection, which can drive connecting block 6 to rotate. When connecting block 6 rotates, it drives the rocker arm 8 to rock through rotating part B 9 via rotating part A 7. Rotating part B 9 drives the frame plate 10 and the swing plate 11 to swing, which can drive the spray head 12 to swing left and right, achieving the effect of left and right spraying. When spraying, blower A 16 is started. Blower A 16 blows air out from the air outlet 13 on the swing plate 11 through the air outlet pipe 15, which achieves the effect of rapid cooling of the surface of the hydrogen cylinder. It can quickly remove the heat, prevent local overheating, and reduce the risk of combustion or explosion of residual gas in the hydrogen cylinder.
