Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, and in particular to a laser cutting apparatus for producing a shell for covering carbonized gas cylinders. Background Technology

[0002] Carbonized gas cylinder shells typically refer to gas cylinders whose exterior is coated with special materials (such as carbides or ceramic coatings) to enhance their performance, particularly in terms of high-temperature resistance, corrosion resistance, and pressure resistance. This coating technology improves the structural strength and service life of the gas cylinder, making it especially suitable for demanding gas storage containers.

[0003] Metal cutting technology is a crucial step in the manufacturing process of carbonized gas canister shells. Metal cutting is used to create openings, cuts, or other machining operations on the canister to meet specific design requirements. Common metal cutting methods include laser cutting, plasma cutting, and mechanical cutting. Among these, laser cutting is widely used in the processing of carbonized gas canister shells due to its advantages in high precision, high efficiency, and high cutting quality.

[0004] Laser cutting uses a concentrated high-energy laser beam to locally heat metal materials to their melting point, thus achieving the cutting process. Because laser cutting does not contact the workpiece, it reduces physical damage to the cladding layer, ensuring its integrity. Furthermore, the smooth, flat cut surface produced by laser cutting avoids the heat-affected zone (HAZ) problem that can occur in traditional cutting methods, thereby minimizing the impact on the metal substrate and cladding layer.

[0005] The prior art publication CN116135410B provides a laser cutting device with a cutting torch anti-collision function. It uses a sensing sleeve to detect whether the cutting mechanism collides with the workpiece. When a collision occurs, it can act as a buffer to prevent the laser emitter from being damaged by the collision. The airbag set at the lower end of the protective sleeve can isolate the cutting point of the invention from the external environment. On the one hand, it can reduce the amount of inert gas used while ensuring that the cutting end face is not oxidized. On the other hand, it can prevent the slag and other debris carried in the inert gas from flying around and polluting the environment inside the frame.

[0006] When cutting holes in the outer shell of a cylindrical carbonized gas cylinder, the existing technology is not convenient for receiving the cutting material, which causes the cut parts to fall into the inner wall of the carbonized gas cylinder and contaminate the inner wall of the gas cylinder. In particular, when there is molten slag or metal fragments, it can easily cause unnecessary pollution to the inside of the gas cylinder.

[0007] In summary, the existing technology lacks a technology for automatically receiving cutting materials when cutting the outer shell of a cylindrical carbonized gas canister. Summary of the Invention

[0008] The purpose of this invention is to address the shortcomings of the prior art by providing a laser cutting device for producing carbonized gas canister shells.

[0009] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a laser cutting device for producing carbonized gas canister shells, comprising a processing table, a gantry frame fixedly mounted on the processing table, a laser cutting device mounted on the gantry frame, a fixed seat fixedly connected to the processing table, a movable seat slidably fitted on the processing table, a positioning ring rotatably connected inside the movable seat, a fixed frame fixedly connected to one side of the movable seat, a movable frame slidably fitted on the fixed frame, a flipping frame rotatably connected to one end of the movable frame, a cutting material receiving mechanism fixedly connected to the flipping frame, and a receiving seat movably inserted into the movable seat.

[0010] Preferably, the fixed base is rotatably connected to an abutment seat.

[0011] Preferably, a hydraulic rod is fixedly connected to the bottom end of the movable seat, and the other end of the hydraulic rod is fixedly connected to the processing table. A motor A is fixedly connected to the upper end of the movable seat, and the output end of the motor A extends through the outer wall of the movable seat into the interior and is fixedly connected to an adjusting wheel.

[0012] Preferably, an annular rack is fixedly connected to the outer wall of the positioning ring, and the annular rack is meshed with the adjusting wheel for transmission. Two electric actuators A are fixedly connected to the inner wall of the positioning ring in a symmetrical structure, and a flange hole positioning rod is fixedly connected to the output end of the electric actuator A.

[0013] Preferably, one end of the fixing frame has two insertion holes, a lead screw is rotatably connected through the fixing frame, a motor B is fixedly connected to one end of the lead screw, the motor B is fixedly connected to the fixing frame, and a transmission rack is fixedly connected to the other end of the fixing frame.

[0014] Preferably, the bottom end of the movable frame is threadedly connected to a lead screw, a worm gear is rotatably connected to one side of the movable frame, a transmission wheel is fixedly connected to the bottom end of the worm gear, the transmission wheel meshes with a transmission rack, and an arc-shaped rack is fixedly connected to one side of the top end of the movable frame.

[0015] Preferably, a rotating shaft is fixedly connected to one end of the tilting frame, and the rotating shaft is rotatably connected to the movable frame. A worm gear is fixedly connected to one end of the rotating shaft, and the worm gear meshes with a worm for transmission. A universal joint is rotatably connected to the tilting frame, and a transmission sleeve is fixedly connected to one end of the universal joint. A gear is fixedly connected to the other end of the universal joint, and the gear meshes with an arc-shaped rack for transmission.

[0016] Preferably, the cutting material receiving mechanism includes a motor C, which is fixedly connected to the flipping frame. The output end of the motor C has two driving wheels fixedly connected in a symmetrical structure. A driven wheel is meshed with one side of the driving wheel. An adjusting rod group is fixedly connected to one end of the driven wheel via a pin. The bottom end of the adjusting rod group is rotatably connected to the flipping frame. A receiving seat is rotatably connected between the top ends of the two adjusting rod groups. An L-shaped scraper is rotatably connected through the inner wall of the receiving seat. A sleeve is fixedly connected to the bottom end of the L-shaped scraper. The sleeve is slidably engaged with the transmission sleeve.

[0017] Preferably, the bottom of the receiving base has two plug rods fixedly connected in a symmetrical structure, and the plug rods are movably connected to the plug holes.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. By setting up a cutting material receiving mechanism, when making opening cuts on the cylindrical carbonized gas canister shell, the tilting frame can drive the cutting material receiving mechanism to extend into the gas canister shell, and through the adjusting rod group, drive the receiving seat to abut against the inner wall of the opening on the gas canister shell, which can effectively receive the cutting material generated during the cutting process, prevent the cutting material from falling into the gas canister, thereby avoiding contamination of the inner wall of the gas canister, ensuring the cleanliness and safety of the gas canister, effectively improving the safety, efficiency and accuracy of the cutting process, while reducing environmental pollution and subsequent cleaning work, and improving the production quality and overall performance of the gas canister;

[0020] 2. By setting up a tilting frame, as the moving frame drives the cutting material receiving mechanism to move out from the inner wall of the gas tank, the tilting frame automatically tilts under the action of the transmission rack, so that the cutting material and slag in the receiving seat can automatically fall into the receiving seat for collection. This can effectively collect cutting material and slag, reduce manual intervention, improve production efficiency and cutting accuracy, reduce pollution of the working environment, reduce maintenance costs, and ultimately improve the automation level of the production process.

[0021] 3. By installing an L-shaped scraper inside the receiving seat, the L-shaped scraper rotates under the action of the arc-shaped rack while the receiving seat is rotated by the tilting frame. This effectively cleans the slag adhering to the inner wall of the receiving seat, ensuring that the receiving seat remains clean and thus guaranteeing the receiving effect.

Detailed Implementation

[0032] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0033] like Figures 1-9The laser cutting device shown is used for producing carbonized gas canister shells. It includes a processing table 1, a gantry frame 2 fixedly mounted on the processing table 1, a laser cutting device 3 mounted on the gantry frame 2, a fixed base 4 fixedly connected to the processing table 1, a movable base 5 slidably mounted on the processing table 1, a positioning ring 6 rotatably connected inside the movable base 5, a fixed frame 7 fixedly connected to one side of the movable base 5, a sliding frame 8 slidably mounted on the fixed frame 7, a flipping frame 9 rotatably connected to one end of the sliding frame 8, a cutting material receiving mechanism 10 fixedly connected to the flipping frame 9, and a receiving seat 11 movably inserted into the movable base 5.

[0034] like Figure 2 As shown, an abutment seat 401 is rotatably connected to the fixed base 4. A rubber pad is provided on the inner wall of the abutment seat 401.

[0035] like Figure 3 As shown, a hydraulic rod 501 is fixedly connected to the bottom of the movable seat 5, and the other end of the hydraulic rod 501 is fixedly connected to the processing table 1. A motor A502 is fixedly connected to the upper end of the movable seat 5. The output end of the motor A502 extends through the outer wall of the movable seat 5 and is fixedly connected to an adjusting wheel 503. The motor A502 drives the connected adjusting wheel 503 to rotate, so that the adjusting wheel 503 can drive the positioning ring 6 connected to the ring rack 601 to rotate, so that the two flange hole positioning rods 603 are aligned with the fixing holes on the flange end of the gas tank shell.

[0036] like Figure 4 As shown, a ring rack 601 is fixedly connected to the outer wall of the positioning ring 6. The ring rack 601 meshes with the adjusting wheel 503 for transmission. Two electric actuators A602 are fixedly connected to the inner wall of the positioning ring 6 in a symmetrical structure. A flange hole positioning rod 603 is fixedly connected to the output end of the electric actuator A602. The hydraulic rod 501 drives the movable seat 5 to move, so that the flange hole positioning rod 603 is inserted into the fixed hole on the flange end of the gas tank shell.

[0037] like Figure 5 As shown, the fixed frame 7 has two insertion holes 701 at one end. A lead screw 702 is rotatably connected through the fixed frame 7. A motor B703 is fixedly connected to one end of the lead screw 702. The motor B703 is fixedly connected to the fixed frame 7. A transmission rack 704 is fixedly connected to the other end of the fixed frame 7. The motor B703 drives the lead screw 702 to rotate, which in turn drives the movable frame 8 to move, allowing the cutting material receiving mechanism 10 on the flipping frame 9 to extend into the gas tank shell.

[0038] like Figure 6As shown, the bottom end of the movable frame 8 is threadedly connected to the lead screw 702, and a worm gear 801 is rotatably connected to one side of the movable frame 8. A transmission wheel 802 is fixedly connected to the bottom end of the worm gear 801. The transmission wheel 802 meshes with the transmission rack 704 for transmission. An arc-shaped rack 803 is fixedly connected to one side of the top of the movable frame 8.

[0039] like Figure 7 As shown, a rotating shaft 901 is fixedly connected to one end of the tilting frame 9. The rotating shaft 901 is rotatably connected to the movable frame 8. A worm gear 902 is fixedly connected to one end of the rotating shaft 901, and the worm gear 902 meshes with the worm 801 for transmission. A universal joint 903 is rotatably connected to the tilting frame 9. A transmission sleeve 904 is fixedly connected to one end of the universal joint 903, and a gear 905 is fixedly connected to the other end of the universal joint 903. The gear 905 meshes with the arc-shaped rack 803 for transmission. Under the action of the transmission rack 704, the transmission wheel 802 drives the connected worm 801 to rotate, which in turn drives the rotating shaft 901 connected to the worm gear 902 to rotate. This allows the rotating frame 9 connected to the rotating shaft 901 to rotate, enabling the receiving seat 1005 to tilt.

[0040] like Figure 8 As shown, the cutting material receiving mechanism 10 includes a motor C1001, which is fixedly connected to the flipping frame 9. The output end of the motor C1001 has two driving wheels 1002 fixedly connected in a symmetrical structure. A driven wheel 1003 is meshed and driven on one side of the driving wheel 1002. An adjusting rod group 1004 is fixedly connected to one end of the driven wheel 1003 by a pin. The bottom end of the adjusting rod group 1004 is rotatably connected to the flipping frame 9. A receiving seat 1005 is rotatably connected between the top ends of the two adjusting rod groups 1004. An L-shaped scraper 1006 is rotatably connected through the inner wall of the receiving seat 1005. A sleeve 1007 is fixedly connected to the bottom end of the L-shaped scraper 1006. The sleeve 1007 is slidably engaged with the transmission sleeve 904. The motor C1001 drives the connected drive wheel 1002 to rotate, which in turn drives the driven wheel 1003 to rotate the adjusting rod assembly 1004. This allows the adjusting rod assembly 1004 to cause the receiving seat 1005 to abut against the inside of the gas tank shell. A rubber ring is fixedly connected to the top of the receiving seat 1005.

[0041] By setting up a cutting material receiving mechanism 10, when making opening cuts on the cylindrical carbonized gas canister shell, the tilting frame 9 can drive the cutting material receiving mechanism 10 to extend into the gas canister shell, and through the adjusting rod assembly 1004, drive the receiving seat 1005 to abut against the inner wall of the opening on the gas canister shell, which can effectively receive the cutting material generated during the cutting process, prevent the cutting material from falling into the gas canister, thereby avoiding contamination of the inner wall of the gas canister, ensuring the cleanliness and safety of the gas canister, effectively improving the safety, efficiency and accuracy of the cutting process, while reducing environmental pollution and subsequent cleaning work, and improving the production quality and overall performance of the gas canister.

[0042] like Figure 9 As shown, the bottom of the receiving base 11 has two plug rods 1101 fixedly connected in a symmetrical structure, and the plug rods 1101 are movably plugged into the plug hole 701.

[0043] Working principle: When it is necessary to cut holes in the cylindrical carbonized gas tank shell, first align one end of the gas tank shell with the abutment seat 401, and adjust the distance between the two flange hole positioning rods 603 according to the position of the fixing hole on the flange end of the gas tank shell. Then, use motor A502 to drive the connected adjusting wheel 503 to rotate, so that the adjusting wheel 503 can drive the positioning ring 6 connected to the ring rack 601 to rotate, so that the two flange hole positioning rods 603 are aligned with the fixing hole on the flange end of the gas tank shell. Then, use hydraulic rod 501 to drive the movable seat 5 to move, so that the flange hole positioning rods 603 are inserted into the fixing hole on the flange end of the gas tank shell, and cooperate with the abutment seat 401 to fix the gas tank shell.

[0044] After determining the opening position, the motor B703 drives the lead screw 702 to rotate, so that the lead screw 702 can drive the moving frame 8 to move, so that the cutting material receiving mechanism 10 on the flipping frame 9 can extend into the gas tank shell. Then, the motor C1001 drives the connected drive wheel 1002 to rotate, so that the drive wheel 1002 can drive the adjusting rod group 1004 connected to the driven wheel 1003 to rotate, so that the adjusting rod group 1004 can drive the receiving seat 1005 to abut against the inside of the gas tank shell.

[0045] Then, the laser cutting equipment 3 is used to cut the gas tank shell. Then, the receiving seat 1005 receives the cutting material and molten slag. After the cutting is completed, the motor C1001 drives the receiving seat 1005 to reset, and the lead screw 702 drives the cutting material receiving mechanism 10 to move out of the gas tank shell.

[0046] Under the action of the transmission rack 704, the transmission wheel 802 drives the connected worm 801 to rotate, which in turn drives the rotating shaft 901 connected to the worm wheel 902 to rotate. This causes the rotating shaft 901 to drive the connected tilting frame 9 to tilt the receiving seat 1005, allowing the cutting material inside the receiving seat 1005 to fall into the receiving seat 11 for collection. At the same time, under the action of the arc-shaped rack 803, the gear 905 drives the connected universal joint 903 to rotate, which in turn drives the transmission sleeve 904 to rotate. This causes the transmission sleeve 904 to drive the L-shaped scraper 1006 connected to the sleeve rod 1007 to rotate, thereby processing the slag adhering to the inner wall of the receiving seat 1005.
