Description

Technical Field

[0001] This utility model relates to the field of flame cutting machines, and in particular to a protective flame cutting machine. 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, using a high-temperature flame generated by a nozzle to melt or oxidize 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, which can easily splash onto surrounding flammable materials and workers, potentially causing safety accidents. At the same time, flame cutting machines produce a large amount of exhaust gas, which can harm the surrounding environment and human health. Therefore, a protective flame cutting machine is needed to address these problems. Utility Model Content

[0003] The main objective of this invention is to provide a protective flame cutting machine that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

The sealed protective cover is also fitted over the flame cutting head. The sealed protective cover consists of a sealing cover, transparent glass, a connecting pipe, and a sealing ring. The transparent glass, connecting pipe, and sealing ring are all fixedly mounted on the sealing cover. A drag-reducing sealing structure is fixedly fitted at the lower part of the sealing cover.

[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 4 As shown, a protective flame cutting machine includes a cutting machine body 1, a movable gantry frame 2 mounted on the cutting machine body 1, a cutting assembly 3 mounted on the movable gantry frame 2, a flame cutting head 4 mounted on the cutting assembly 3, a connecting bracket 5 fixedly mounted on the cutting assembly 3, and a sealed protective cover 6 fixedly mounted on the connecting bracket 5. The sealed protective cover 6 is also fitted onto the flame cutting head 4. The sealed protective cover 6 consists of a sealing cover 8, a transparent glass 12, a connecting pipe 13, and a sealing ring 14. The transparent glass 12, the connecting pipe 13, and the sealing ring 14 are all fixedly mounted on the sealing cover 8. The lower part is fixedly fitted with a drag-reducing and sealing structure 7, which consists of a mounting base ring 15 and supporting balls 17. There are several supporting balls 17, all of which are rotatably installed in the mounting base ring 15. When using the flame cutting machine, the metal plate to be cut can be placed on the main body 1 of the cutting machine. Then, as the moving gantry 2 and the cutting assembly 3 work, the flame cutting head 4 will cut the metal plate. During this process, the sealed protective cover 6 fitted on the flame cutting head 4 can block the sparks generated by the cutting, while the supporting balls 17 on the drag-reducing and sealing structure 7 will rotate due to friction with the metal plate.

[0020] By setting up the connecting bracket 5, the sealed protective cover 6, and the drag-reducing sealing structure 7, and by placing the sealed protective cover 6 on the flame cutting head 4, the sparks can be blocked, thereby preventing the sparks from splashing onto the surrounding flammable materials and the workers, thus reducing the probability of safety accidents. At the same time, the sealed protective cover 6, in conjunction with the exhaust gas purification equipment, can collect and purify the exhaust gas, thereby preventing the exhaust gas from causing harm to the surrounding environment and human health.

[0021] Specifically, the connecting bracket 5 is fixedly connected to the cutting component 3 and the sealing cover 8 respectively by bolts. The upper side wall of the sealing cover 8 on the sealed protective cover 6 has a fitting hole 11, and several installation windows 9 are opened on the side wall of the sealing cover 8. Simultaneously, an insertion hole 10 is opened on the side wall of the sealing cover 8. The transparent glass 12 on the sealed protective cover 6 is fixedly installed in the installation window 9 opened on the side wall of the sealing cover 8. The connecting pipe 13 is fixedly inserted into the insertion hole 10 opened on the side wall of the sealing cover 8. The connecting pipe 13 can be connected to the exhaust gas purification equipment through a flexible hose. The sealing ring 14 is fixedly installed in the fitting hole 11 opened on the upper side wall of the sealing cover 8. The sealing ring on the sealed protective cover 6... The cover 8 is fitted onto the flame cutting head 4 through the fitting hole 11. The inner wall of the sealing ring 14 is in contact with the flame cutting head 4. During the process of the flame cutting head 4 cutting the metal plate, the operator can observe the working status of the flame cutting head 4 through the transparent glass 12. At the same time, during the process of the flame cutting head 4 cutting the metal plate, the exhaust gas purification equipment connected to the sealed protective cover 6 through the hose can be started. At this time, the sealed protective cover 6 can block the exhaust gas generated by the flame cutting head 4 cutting the metal plate, and the exhaust gas purification equipment will suck away and purify the exhaust gas blocked by the sealed protective cover 6. During this process, the exhaust gas in the sealed cover 8 will enter the exhaust gas purification equipment through the connecting pipe 13 and the hose in sequence.

[0022] Specifically, the mounting base ring 15 on the drag-reducing and sealing structure 7 is fixedly sleeved on the lower part of the sealing cover 8. Several spherical grooves 16 are opened on the mounting base ring 15, which passes through the mounting base ring 15 vertically. The support ball 17 is rotatably installed in the spherical groove 16. When installing and using the drag-reducing and sealing structure 7, the drag-reducing and sealing structure 7 needs to have a suitable height so that the support ball 17 can contact the upper end of the metal plate placed on the cutting machine body 1. On the one hand, it can effectively block the exhaust gas and sparks from escaping outward. On the other hand, it can reduce the resistance when the flame cutting head 4 moves to cut the metal plate. Therefore, when the moving gantry 2, cutting assembly 3, flame cutting head 4, connecting bracket 5, sealing protective cover 6 and drag-reducing and sealing structure 7 move, the support ball 17 will rub against the metal plate, and the support ball 17 will rotate in the spherical groove 16.
