Description

Technical Field

[0001] This utility model relates to the field of flame cutting machines, and in particular to a flame cutting machine that prevents sparks from flying. Background Technology

[0002] Flame cutting machines are devices that use gas-oxygen fuel or gasoline-oxygen fuel to cut metal materials, and are widely used in the metal processing industry. They are based on the principle of metal combustion and oxidation at high temperatures. A high-temperature flame generated by a nozzle melts or oxidizes the metal, thus achieving cutting. Flame cutting machines are mainly divided into manual cutting, semi-automatic cutting, contour cutting, and CNC cutting types. Among them, CNC flame cutting machines achieve full automation of the cutting process, significantly improving cutting quality and production efficiency. When a flame cutting machine cuts metal plates, a large amount of sparks are generated. These sparks are bright and dazzling, easily affecting the eyesight of nearby workers. Furthermore, the sparks can easily splash onto nearby flammable materials and workers, potentially causing safety accidents. Therefore, a flame cutting machine that prevents spark splashing is needed. Utility Model Content

A protective component is fixedly mounted on both the first and second connecting members, and the protective component is simultaneously fitted with... Outside the flame cutting assembly, the protective assembly consists of a fixed enclosure, a first connecting plate, guide rods, an anti-detachment plate, springs, a movable enclosure, a second connecting plate, base plates, and ball bearings. Several first connecting plates are symmetrically fixedly installed on the upper outer wall of the fixed enclosure. Several guide rods are fixedly installed at the lower ends of several first connecting plates. Several springs are respectively sleeved on several guide rods. The movable enclosure is movably sleeved on the fixed enclosure. Several second connecting plates are symmetrically fixedly installed on the upper outer wall of the movable enclosure. Four base plates are symmetrically fixedly installed on the lower outer wall of the movable enclosure. Several ball bearings are rotatably installed on several base plates.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a flame cutting machine for preventing sparks includes a cutting machine body 1, a movable component 2 mounted on the cutting machine body 1, a flame cutting component 3 mounted on the movable component 2, and two mounting plates 4 symmetrically fixed at both ends of the movable component 2. One mounting plate 4 has a first connecting member 5 mounted on it, consisting of an L-shaped connecting rod 8 and a top plate 9, with the top plate 9 fixedly mounted on the upper end of the L-shaped connecting rod 8. The other mounting plate 4 has a second connecting member 6 mounted on it, consisting of a support rod 10, a support plate 11, and a threaded rod 12, with the support plate 11 fixedly mounted on one end of the support rod 10 and the threaded rod 12 rotating. A protective assembly 7 is fixedly installed on the first connecting member 5 and the second connecting member 6, mounted on the support plate 11. The protective assembly 7 is also sleeved on the outside of the flame cutting assembly 3. The protective assembly 7 consists of a fixed enclosure plate 13, a first connecting plate 14, guide rods 15, an anti-detachment plate 16, a spring 17, a movable enclosure plate 18, a second connecting plate 19, a base plate 21, and ball bearings 23. Several first connecting plates 14 are symmetrically fixedly installed on the upper outer wall of the fixed enclosure plate 13. Several guide rods 15 are respectively fixedly installed on the lower ends of several first connecting plates 14. Several springs 17 are respectively sleeved on several guide rods 15. The movable enclosure 18 is movably fitted onto the fixed enclosure 13. Several second connecting plates 19 are symmetrically and fixedly installed on the upper outer wall of the movable enclosure 18. Four base plates 21 are symmetrically and fixedly installed on the lower outer wall of the movable enclosure 18. Several ball bearings 23 are rotatably installed on several base plates 21. When the flame cutting machine cuts metal plates to process workpieces, the raw metal plate can first be placed on the upper end of the cutting machine body 1. Then, the movable component 2 and the flame cutting component 3 can be started to cut the metal plate. While the movable component 2 drives the flame cutting component 3 to move and cut the metal plate on the cutting machine body 1, the protective component 7 will... To block the generated sparks, the moving enclosure 18 moves downwards towards the metal plate under the elastic force of the spring 17, and the ball bearing 23 comes into contact with the metal plate. As the protective component 7 moves with the moving component 2, the ball bearing 23 rubs against the metal plate and rotates. When the ball bearing 23 cannot come into contact with the metal plate due to the elastic force of the spring 17, the height of the protective component 7 can be adjusted by the first connecting member 5 and the second connecting member 6, so that the ball bearing 23 can come into contact with the metal plate and the protective component 7 has a better blocking effect on the flame cutting component 3, thus making the protective component 7 better at preventing sparks from flying.

[0020] Therefore, by setting up the protective component 7, the flame cutting component 3 can be enclosed, thereby blocking the sparks generated when the flame cutting component 3 cuts the metal plate. On the one hand, it can prevent the sparks from injuring the eyes of the surrounding workers, and on the other hand, it can prevent the sparks from splashing onto the surrounding flammable materials and the workers, thereby reducing the probability of safety accidents. At the same time, the presence of the ball bearing 23 and the elastic force of the spring 17 allow the movable enclosure 18 to move up and down on the fixed enclosure 13. This allows the movable enclosure 18 to approach the metal plate being cut and effectively block the sparks without affecting the movement of the flame cutting component 3 to cut the metal plate. By setting up the first connecting member 5 and the second connecting member 6, the height of the protective component 7 can be adjusted, thereby enabling the protective component 7 to further effectively block the sparks.

[0021] Specifically, one of the mounting plates 4 has a through hole, and the other mounting plate 4 has a threaded hole. The L-shaped connecting rod 8 on the first connecting member 5 is slidably installed in the through hole on one of the mounting plates 4. The top plate 9 is located above one of the mounting plates 4. The threaded rod 12 on the second connecting member 6 is installed in the threaded hole on the other mounting plate 4. The support rod 10 and the support plate 11 are both located below the other mounting plate 4. When adjusting the height of the protective component 7, the threaded rod 12 can be rotated in the threaded hole on the mounting plate 4. At this time, the L-shaped connecting rod 8 can limit the protective component 7, thereby preventing the protective component 7 from rotating with the threaded rod 12. As the threaded rod 12 rotates, the threaded rod 12 will drive the protective component 7 to move up or down through the support plate 11 and the support rod 10.

[0022] Furthermore, the fixed enclosure 13 on the protective assembly 7 is fixedly connected to the L-shaped connecting rod 8 and the support rod 10. The fixed enclosure 13 is also sleeved on the outside of the flame cutting assembly 3. The movable enclosure 18 on the protective assembly 7 is located below the first connecting plate 14. The second connecting plate 19 has a mounting hole 20. The second connecting plate 19 is movably sleeved on the guide rod 15 through the mounting hole 20. The second connecting plate 19 is also located below the spring 17. The lower end of the base plate 21 on the protective assembly 7 has a spherical groove 22. The ball bearing 23 is rotatably mounted on the ball bearing. Within the groove 22, the protective component 7 moves along with the movable component 2. The movable enclosure 18, the second connecting plate 19, the base plate 21, and the ball bearing 23 can move up and down on the guide rod 15 and the fixed enclosure 13 under the elastic force of the spring 17 and the supporting force of the metal plate. When the movable enclosure 18, the second connecting plate 19, the base plate 21, and the ball bearing 23 move upward, the spring 17 is compressed. Conversely, when the movable enclosure 18, the second connecting plate 19, the base plate 21, and the ball bearing 23 move downward, the spring 17 extends.
