Description

A protective flame cutter that prevents splashing. Technical Field

[0001] This utility model relates to the field of flame cutting machine technology, specifically a protective flame cutting machine that prevents splashing. Background Technology

[0002] Flame cutting machines are commonly used for cutting metal sheets and pipes. Especially when the steel plate is thick, flame cutting can achieve better cutting results. Flame cutting uses a flame that mixes combustible gas and oxygen to preheat the workpiece to a certain temperature. Then, a high-speed cutting oxygen stream is sprayed out, which causes the metal to oxidize violently and release heat. The cutting oxygen stream blows away the molten metal oxides, thus achieving the cutting.

[0003] However, existing flame cutting machines still have some problems in use:

[0004] An existing example is a flame cutting machine with application number CN201520222568.8, which includes a flame cutting machine tool, a flame cutting machine and a track. The flame cutting machine is installed on the track, and a seat with rollers at the bottom is placed on the track. The seat and the flame cutting machine are fixed together as a whole by a connecting rod.

[0005] Existing flame cutting machines generate a large amount of high-temperature metal shavings, sparks and other spatter during the flame cutting process. These spatters can easily burn operators and pose a significant safety hazard. Furthermore, if they splash onto other parts of the equipment or the working environment, they may damage the equipment, pollute the environment, and affect the accuracy and efficiency of the cutting work.

[0006] Therefore, we propose a splash-proof protective flame cutter to address the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a protective flame cutting machine that prevents splashing, in order to solve the problem mentioned in the background art that flame cutting machines generate a large amount of high-temperature metal shavings, sparks and other splashes during the flame cutting process. These splashes not only easily burn operators and pose a significant safety hazard, but also may damage the equipment and pollute the environment if they splash onto other parts of the equipment or the working environment. At the same time, they also affect the accuracy and efficiency of the cutting work.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a splash-proof protective flame cutting machine, comprising a worktable and a controller:

[0009] A controller is installed on one side of the workbench, and a fixed frame is provided above the workbench. A first sliding groove is opened on the outer side of the fixed frame, and a second motor is installed at the top of the fixed frame. A threaded shaft is rotatably connected to the output end of the second motor and located in the middle of the first sliding groove. Two sets of inner protective plates are symmetrically installed on one side of the fixed frame. A second slider is fixed to the inner protective plate and located on one side of the fixed frame. Two sets of second electric push rods are installed at the front end of the inner protective plate, and the extended ends of the second electric push rods are fixedly connected to the outer protective plate.

[0010] By adopting the above technical solution, the threaded shaft is driven to rotate by the second motor, which drives the inner guard plate to rise and fall along the first slide groove, thereby adapting to the protection requirements of different workpiece heights. Then, the outer guard plate is pushed to extend by the second electric push rod, which can form a double-layer protection structure with the inner guard plate, so as to effectively block the spatter generated during cutting, improve the safety of operation, and prevent the spatter from damaging the equipment or polluting the environment.

[0011] Preferably, the second slider is threadedly connected to the threaded shaft, and the second slider is in a sliding fit with the first groove.

[0012] With the above technical solution, when the second motor drives the threaded shaft to rotate, the second slider, which is threadedly connected to the threaded shaft, moves linearly along the threaded shaft and drives the inner guard plate to rise and fall, so that the protective device can flexibly adjust its position according to the height of the workpiece, ensuring a good anti-splash effect when cutting workpieces of different sizes.

[0013] Preferably, a second sliding groove is provided on the outer side of the inner protective plate, and a third slider that is slidably connected to the second sliding groove is fixed on the inner side of the outer protective plate.

[0014] Using the above technical solution, the outer protective plate slides with the second sliding groove on the outer side of the inner protective plate through the third slider on the inner side. When the second electric push rod pushes the outer protective plate, the third slider slides smoothly along the second sliding groove to realize the extension and contraction of the outer protective plate. This ensures that the outer protective plate remains stable during the extension and contraction process, avoids shaking or displacement, and enhances the reliability of the protective structure and the blocking effect on splashes.

[0015] Preferably, a fixing rod is fixed to the upper surface of the workbench, a first motor is installed on one side of the fixing rod, a lead screw is movably connected to the output end of the first motor, and the bottom end of one side of the fixing frame is threadedly connected to the lead screw.

[0016] By adopting the above technical solution, the first motor drives the lead screw to rotate, which can drive the fixed frame connected to the lead screw to move linearly along the lead screw, so that the fixed frame can move horizontally above the worktable, making it easy to adjust the protective position to adapt to different cutting positions and improve the equipment's flexibility in protecting diverse workpieces.

[0017] Preferably, a slide rail is fixed to the upper end surface of the workbench, and a first slider that is slidably connected to the slide rail is fixed to the bottom end of the other side of the fixing frame.

[0018] By adopting the above technical solution, the fixed frame is slidably connected to the slide rail of the worktable through the first slider at the bottom, which can provide guidance and support for the fixed frame and ensure the stability of the fixed frame during movement.

[0019] Preferably, a first electric push rod is installed on the rear side of the fixing frame, the extended end of the first electric push rod is fixed with a mounting base, and the mounting base is slidably connected to the fixing frame. A flame cutting head is installed on the outer side of the mounting base, the upper end of the flame cutting head is connected to an oxygen pipe, and the other end of the oxygen pipe is connected to a controller.

[0020] Using the above technical solution, the first electric push rod pushes the mounting base to slide along the fixed frame, thereby driving the flame cutting head to adjust its horizontal position. The oxygen pipe supplies oxygen to the cutting head and adjusts the gas parameters through the controller. The electric push rod enables flexible control of the horizontal position of the cutting head to adapt to the cutting needs of different workpieces. At the same time, combined with the gas supply and control of the oxygen pipe, the cutting process is ensured to be stable and efficient, improving the versatility of the equipment and the cutting quality.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. The second motor drives the threaded shaft to rotate, which in turn drives the second slider, which is threadedly connected to the second slider and slidably connected to the first slide groove, to move. This allows the inner guard plate to move up and down along the fixed frame to accommodate workpieces of different heights. The second slide groove on the outer side of the inner guard plate slides in conjunction with the third slider on the inner side of the outer guard plate. When the second electric push rod extends or retracts, it can push the outer guard plate to slide smoothly along the second slide groove, thus extending and retracting the protection range. The adjustable height inner guard plate and the retractable outer guard plate work together to effectively block high-temperature metal chips, sparks, and other flying debris generated during flame cutting, preventing injury to operators or damage to surrounding equipment. At the same time, the protective structure can be flexibly adjusted according to actual cutting needs to improve the protective effect and the applicability of the equipment.

[0023] 2. The first motor drives the lead screw to rotate, causing the fixed frame to move horizontally along the slide rail to adjust the cutting position. When the first electric push rod on the rear side of the fixed frame extends or retracts, it pushes the mounting base, which is slidably connected to the fixed frame, to move horizontally, thereby adjusting the horizontal position of the flame cutting head to meet the processing requirements of different workpieces. The oxygen pipe connects the flame cutting head to the controller to deliver oxygen and control gas parameters, allowing the equipment to flexibly adjust the position of the cutting head in both horizontal and vertical directions. Combined with the controller's precise control of the gas, efficient cutting operations are achieved. At the same time, the protective structure blocks splashes, improving cutting accuracy and safety. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Please refer to Figures 1-5. This utility model provides a technical solution: a splash-proof protective flame cutting machine, including a worktable 1 and a controller 2. The controller 2 is installed on one side of the worktable 1, and a fixed frame 6 is provided above the worktable 1. A first sliding groove 13 is opened on the outer side of the fixed frame 6. A second motor 14 is installed at the top of the fixed frame 6. A threaded shaft 15 is rotatably connected to the output end of the second motor 14, located in the middle of the first sliding groove 13. Two sets of inner protective plates 16 are symmetrically installed on one side of the fixed frame 6. A second slider 17 is fixed to the inner protective plate 16, located on one side of the fixed frame 6. Two sets of second electric push rods 18 are installed at the front end of the inner protective plate 16. The protruding ends of the second electric push rods 18 are fixedly connected to an outer protective plate 19. The second slider 17 is threadedly connected to the threaded shaft 15, and the second slider 17 is in close sliding connection with the first sliding groove 13. A second sliding groove 20 is opened on the outer side of the inner protective plate 16, and a third slider 21, which is slidably connected to the second sliding groove 20, is fixed on the inner side of the outer protective plate 19.

[0032] After the second motor 14 starts, it drives the threaded shaft 15 to rotate in the first slide groove 13. Since the second slider 17 is threadedly connected to the threaded shaft 15 and slides in close contact with the first slide groove 13, the inner guard plate 16 can move up and down along the fixed frame 6 to adapt to cutting workpieces of different heights. The second slide groove 20 on the outer side of the inner guard plate 16 slides in cooperation with the third slider 21 on the inner side of the outer guard plate 19. When the second electric push rod 18 extends or retracts, it can push the outer guard plate 19 to slide smoothly along the second slide groove 20, realizing the extension and contraction of the protection range. In order to effectively block the high-temperature metal chips, sparks and other splashes generated during the flame cutting process through the cooperation of the adjustable height inner guard plate 16 and the retractable outer guard plate 19, the splashes can avoid injury to the operator or damage to the surrounding equipment. At the same time, the protective structure can be flexibly adjusted according to the actual cutting needs to improve the protective effect and the applicability of the equipment.

[0033] A fixing rod 3 is fixed to the upper surface of the workbench 1. A first motor 4 is installed on one side of the fixing rod 3. A lead screw 5 is movably connected to the output end of the first motor 4, and the bottom end of one side of the fixing frame 6 is threadedly connected to the lead screw 5. A slide rail 7 is fixed to the upper surface of the workbench 1, and a first slider 8 is fixed to the bottom end of the other side of the fixing frame 6 and is slidably connected to the slide rail 7. A first electric push rod 9 is installed on the rear side of the fixing frame 6. A mounting base 10 is fixed to the extended end of the first electric push rod 9, and the mounting base 10 is slidably connected to the fixing frame 6. A flame cutting head 11 is installed on the outer side of the mounting base 10. An oxygen pipe 12 is connected to the upper end of the flame cutting head 11, and the other end of the oxygen pipe 12 is connected to the controller 2.

[0034] The first motor 4 drives the lead screw 5 to rotate. The bottom end of one side of the fixed frame 6 is threadedly connected to the lead screw 5, and the first slider 8 at the bottom end of the other side slides with the slide rail 7 on the worktable 1, so that the fixed frame 6 can move horizontally along the slide rail 7, thereby adjusting the cutting position. When the first electric push rod 9 on the rear side of the fixed frame 6 extends or retracts, it pushes the mounting seat 10, which is slidably connected to the fixed frame 6, to move horizontally, thereby adjusting the horizontal position of the flame cutting head 11 to adapt to the processing requirements of different workpieces. The oxygen pipe 12 connects the flame cutting head 11 to the controller 2, and is used to deliver oxygen and control gas parameters, so that the equipment can flexibly adjust the position of the cutting head in the horizontal and vertical directions. Combined with the precise control of the gas by the controller 2, efficient cutting operation is achieved. At the same time, the protective structure blocks the splashes, improving cutting accuracy and safety.

[0035] Working Principle: For this type of anti-splash protective flame cutting machine, the first motor 4 drives the lead screw 5 to rotate. Since the bottom end of one side of the fixed frame 6 is threadedly connected to the lead screw 5, and the first slider 8 at the bottom end of the other side slides against the slide rail 7 on the worktable 1, the fixed frame 6 moves smoothly on the worktable 1, achieving initial adjustment of the cutting position. Simultaneously, the second motor 14 at the top of the fixed frame 6 drives the threaded shaft 15 to rotate in the first slide groove 13. The second slider 17, threadedly connected to the threaded shaft 15 and sliding against the first slide groove 13, drives the inner protective plate 16 to move up and down along the fixed frame 6, thus adapting to cutting workpieces of different heights. When the second electric push rod 18 at the front end of the inner protective plate 16 extends or retracts, it... The third slider 21, which slides in conjunction with the second slide groove 20, pushes the outer protective plate 19 to slide smoothly along the second slide groove 20, thereby extending and retracting the protective range. In addition, the extension and retraction of the first electric push rod 9 on the rear side of the fixing frame 6 will push the mounting base 10, which is slidably connected to the fixing frame 6, to move horizontally, thereby driving the flame cutting head 11 to adjust its horizontal position. The oxygen pipe 12 connects the flame cutting head 11 to the controller 2, and the controller 2 precisely controls the oxygen delivery parameters to provide stable energy for cutting. This allows the equipment to flexibly adjust the position of the cutting head in both horizontal and vertical directions. The adjustable and retractable inner protective plate 16 and outer protective plate 19 effectively block splashes, ultimately achieving efficient, safe, and precise cutting operations.

[0036] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
