[0001] This utility model relates to the field of flame cutting technology, specifically to a fast and efficient flame cutting device. Background Technology
[0002] A flame cutting machine is a device that uses a high-temperature flame to cut metal. It mainly uses oxygen and fuel to ignite and spray a high-temperature flame onto the metal sheet, which rapidly heats and melts the sheet, ultimately achieving the cutting process. However, sparks are easily scattered during the cutting process, posing certain safety hazards. Therefore, a protective device needs to be designed for the cutting process. At the same time, existing cutting devices lack clamping devices, causing the cutting edge to deviate, resulting in material waste. Therefore, a fast and efficient flame cutting device has been designed to address the above problems.

By incorporating an air intake and filtration device, it effectively collects and treats the exhaust gases generated during flame cutting, thereby ensuring good air quality in the operator's working environment and protecting their health. The solution is effective and worthy of promotion.
[0004] Based on existing solutions and actual production and processing, current flame cutting devices still have some problems: it is not convenient to protect the cutting area of the flame cutting device, it is not convenient to adjust the cutting size of the metal on the flame cutting device, it is not convenient to clamp and limit metal plates of different sizes and thicknesses on the flame cutting device, and it is impossible to avoid the phenomenon of cutting deviation. Therefore, this utility model provides a fast and efficient flame cutting device to solve the above-mentioned problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fast and efficient flame cutting device, comprising: a workbench for installation, and first threaded rods stably installed on the left and right sides of the workbench;
[0007] It also includes: a protective mechanism is provided at the front end of the first threaded rod, wherein the protective mechanism includes a protective shell, a first bevel tooth and a second bevel tooth, the front end of the first threaded rod is equipped with a protective shell and a first bevel tooth, and the first bevel tooth is located at the front end of the protective shell, and the front end of the first bevel tooth is connected to the second bevel tooth;

A sliding rod is provided at the front end of the clamping plate, and a second spring is provided on the outer side of the sliding rod.
[0009] Preferably, the front end of the first bevel tooth is connected to the second bevel tooth by meshing, and the second bevel tooth is provided with a transmission rod inside, and a handle is installed on the left end of the transmission rod.
[0010] Preferably, a support frame is provided on the upper front side of the workbench, and an electromagnetic slide rail is provided in the middle of the support frame. An electromagnetic block is connected to the outer side of the electromagnetic slide rail, and a nozzle is installed at the front end of the electromagnetic block.
[0011] Preferably, a second threaded rod is provided at the left rear end of the support frame, and the outer side of the second threaded rod is connected to the connecting plate by a thread, and a motor is installed at the rear end of the second threaded rod.
[0012] Preferably, the fixing rod is symmetrically arranged about the center line of the connecting plate, and the outer side of the fixing rod is in contact with the first spring, and the clamping plate forms a sliding structure on the outer side of the fixing rod.
[0013] Preferably, the sliding rod forms a sliding structure on the right side of the front end of the clamping plate, and the second spring is set in a contact state on the outer side of the lower end of the sliding rod.
[0014] Compared with the prior art, the beneficial effects of this utility model are: the fast and efficient flame cutting device makes it easy to protect the cutting area of the flame cutting device, makes it easy to adjust the cutting size of the metal on the flame cutting device, and makes it easy to clamp and limit metal plates of different sizes and thicknesses on the flame cutting device to avoid the phenomenon of cutting deviation.
[0015] 1. The device is equipped with a first threaded rod, a protective shell, and a handle. Since the flame cutting device cuts different materials in different ways, the size of the sparks produced during cutting will also vary. Therefore, it is necessary to adjust the protective device to ensure comprehensive protection. Holding the handle drives the transmission rod and the second bevel gear to rotate. The second bevel gear meshes with the first bevel gear, so the second bevel gear drives the first threaded rod to rotate through the first bevel gear. This causes the first threaded rod to move backward along the threaded path connected to the left and right sides of the worktable. When the first threaded rod moves, it drives the protective shell to move backward, thereby adjusting the protective distance and facilitating the protection of the cut area of the flame cutting device.
[0016] 2. It is equipped with a second threaded rod, a connecting plate and a motor. When the rear end of the plate to be cut is limited by the clamping device on the connecting plate, the motor is started to drive the second threaded rod to rotate. The second threaded rod then drives the connecting plate to move back and forth, adjusting the spacing of the plate to be cut, which makes it easy to adjust the cutting size of the metal on the flame cutting device.
[0017] 3. Equipped with a connecting plate, clamping plate, and sliding rod, when it is necessary to clamp and fix the metal sheet to be cut, first adjust the clamping device according to the length of the metal sheet. The rear end of the metal sheet slides backward through the inclined groove at the front end of the clamping plate, so that the two ends of the metal sheet drive the clamping plate to squeeze the first spring along the path of the fixing rod, so that the clamping plate can clamp the sheet of different sizes. However, when the sheet enters the middle of the clamping plate, due to the different thicknesses of the sheet, it is necessary to slide the sliding rod upward to squeeze the second spring to retract until the upper end of the metal sheet is parallel to the lower end of the sliding rod. Then, release the sliding rod, and the second spring will use its elasticity to drive the sliding rod to clamp the upper end of the sheet, which is convenient for clamping and limiting metal sheets of different sizes and thicknesses on the flame cutting device to avoid the cutting deviation.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1-6 As shown, this utility model provides a technical solution: a fast and efficient flame cutting device, including a worktable 1, a first threaded rod 2, a protective shell 3, a first bevel tooth 4, a second bevel tooth 5, a transmission rod 6, a handle 7, a support frame 8, an electromagnetic slide rail 9, an electromagnetic block 10, a fuel control box 11, a nozzle 12, a second threaded rod 13, a connecting plate 14, a motor 15, a fixing rod 16, a first spring 17, a clamping plate 18, a sliding rod 19, and a second spring 20.
[0027] When confining the metal sheet to be cut on the flame cutting device, for example, with... Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 As shown and attached Figure 5As shown, the fixing rod 16 is symmetrically arranged about the center line of the connecting plate 14. The outer side of the fixing rod 16 is in contact with the first spring 17. The clamping plate 18 forms a sliding structure on the outer side of the fixing rod 16, and the sliding rod 19 forms a sliding structure on the right side of the front end of the clamping plate 18. The second spring 20 is in contact with the outer side of the lower end of the sliding rod 19. First, the metal sheet to be cut is placed on the worktable 1. The rear ends of the metal sheet slide backward through the inclined groove at the front end of the clamping plate 18, so that the two ends of the metal sheet drive the clamping plate 18 to press the first spring 17 along the path of the fixing rod 16. A spring 17 allows the clamping plate 18 to hold plates of different sizes. However, when the plates enter the middle of the clamping plate 18, due to the different thicknesses of the plates, the sliding rod 19 needs to slide upward to compress the second spring 20 until the upper end of the metal plate is parallel to the lower end of the sliding rod 19. Then, the sliding rod 19 is released, and the second spring 20 uses its elasticity to drive the sliding rod 19 to clamp the upper end of the plate. This achieves the clamping and fixing of plates of different lengths and thicknesses, preventing deviation during cutting and affecting cutting efficiency. This is the way the plate is limited on the flame cutting device.
[0028] When using fast and efficient flame cutting devices, such as those with... Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 6As shown, the front end of the first bevel tooth 4 is connected to the second bevel tooth 5 by meshing. A transmission rod 6 is installed inside the second bevel tooth 5, and a handle 7 is installed at the left end of the transmission rod 6. A support frame 8 is installed on the upper front side of the workbench 1. An electromagnetic slide rail 9 is installed in the middle of the support frame 8, and an electromagnetic block 10 is connected to the outer side of the electromagnetic slide rail 9. A nozzle 12 is installed at the front end of the electromagnetic block 10. A second threaded rod 13 is installed at the rear left side of the support frame 8. The outer side of the second threaded rod 13 is connected to the connecting plate 14 by threads. A motor 15 is installed at the rear end of the second threaded rod 13. After the metal plate is positioned, the motor 15 is started to drive the second threaded rod 13 to rotate. The second threaded rod 13 then drives the connecting plate 14 to move forward, causing the part of the plate to be cut to protrude to the lower end of the nozzle 12. At this point, the motor 15 is stopped, and the electromagnetic block 10 is started again to drive the nozzle 12 to move forward. The nozzle 12 is moved downwards, bringing its lower end close to the upper end of the material to be cut. Then, the protective distance of the protective shell 3 is adjusted according to the nozzle 12 to prevent sparks from the cutting from injuring the workers. The handle 7 is held to drive the transmission rod 6 and the second bevel tooth 5 to rotate. The second bevel tooth 5 meshes with the first bevel tooth 4, so the second bevel tooth 5 drives the first threaded rod 2 to rotate through the first bevel tooth 4. This causes the first threaded rod 2 to move backward along the threaded path connected to the left and right sides of the worktable 1. When the first threaded rod 2 moves, it drives the protective shell 3 to move backward. After adjusting the protective device, the switch at the rear end of the fuel control box 11 is turned on. The fuel control box 11 supplies cutting fuel to the nozzle 12 through the pipeline, and the lower end of the nozzle 12 sprays out cutting flames. Then, the electromagnetic slide rail 9 is turned on to drive the support frame 8 to move left and right, thus achieving the cutting of the material. This is the way to use the fast and efficient flame cutting device.
