Abstract
Description
Technical Field
[0001] This utility model relates to the field of thermal cutting equipment technology, and specifically to a thermal cutting device with high safety. Background Technology
[0002] Thermal cutting is a cutting process frequently used in many fields such as industrial production and metal processing. Its principle is to use a high-temperature heat source (such as plasma arc, laser beam, oxyacetylene flame, etc.) to locally heat the workpiece, so that it reaches the melting point or ignition point, thereby achieving the purpose of material separation.
[0003] Currently common thermal cutting equipment includes oxy-acetylene flame cutting equipment, plasma arc cutting equipment, and laser cutting equipment. Although these existing devices have shells, they are mostly made of thin metal sheets, which can only block some of the splashing molten slag and radiant heat. During the cutting process, when encountering workpieces with uneven material or large fluctuations in cutting parameters that produce significant molten slag splashes, these slags may still penetrate the protective gaps and injure the operator. Moreover, the strong light and electromagnetic radiation generated by the plasma arc are only partially attenuated by conventional transparent protective plates, and long-term operation can easily damage the operator's eyesight and physical functions. Utility Model Content
[0004] The purpose of this invention is to address the problems of existing thermal cutting equipment protective designs not fully considering extreme working conditions and long-term cumulative hazards, the high possibility of molten slag, strong light, radiation and other hazardous factors breaking through the protective barrier, and the fact that operators are exposed to harsh environments for a long time, making their eyes susceptible to strong light burns and occupational diseases, and their skin susceptible to scalds and burns. This invention provides a highly safe thermal cutting device that can block various sources of harm, ensure the safety of personnel throughout the operation, significantly improve the safety of thermal cutting, and facilitate stable and efficient thermal cutting operations.
[0005] This utility model is achieved through the following technical solution: This utility model provides a highly safe thermal cutting device, including a thermal cutting device and a protective cover. The thermal cutting device is set on a cutting platform. The protective cover includes a fixed protective cover and a movable protective cover. Both the fixed and movable protective covers include a semi-circular shell and a top plate fixed to the upper end of the shell. The fixed protective cover is set on the cutting platform. The movable protective cover is rotatably installed inside the fixed protective cover. After the movable protective cover rotates 180° around the axis of the fixed protective cover, it and the fixed protective cover together cover the thermal cutting device.
[0006] As a preferred embodiment of this utility model, the fixed protective cover is rotatably mounted on the cutting platform, and the fixed protective cover rotates about its axis.
[0007] As a preferred embodiment of this utility model, an annular limiting plate is fixedly provided on the cutting platform, and an annular rotating plate is rotatably installed on the inner side of the annular limiting plate. The top surface of the annular rotating plate is fixedly connected to the lower end of the fixed protective cover.
[0008] As a preferred embodiment of this utility model, it further includes a driving component for driving the annular rotating plate to rotate, the driving component being connected to the annular rotating plate in a transmission connection.
[0009] As a preferred embodiment of the present invention, the driving component includes a first motor, the output shaft of the first motor is provided with a gear, and the annular rotating plate is provided with gear teeth that mesh with the gear.
[0010] As a preferred embodiment of this utility model, the first motor is fixedly installed on the cutting platform.
[0011] As a preferred embodiment of this utility model, a second motor is provided at the upper end of the fixed protective cover, and the output shaft of the second motor passes through the fixed protective cover and is connected to the moving protective cover.
[0012] As a preferred embodiment of this utility model, a protective film for shading is adhered to the outer side of the fixed protective cover.
[0013] As a preferred embodiment of this utility model, a protective film for shading light is adhered to the outer side of the dynamic protective cover.
[0014] As a preferred embodiment of this utility model, the protective film is a dark-colored light-blocking film.
[0015] Compared with the prior art, this utility model has the following advantages and beneficial effects: 1. When using the equipment, place the workpiece on the cutting platform and perform thermal cutting.

[0028] Please refer to Figures 1 to 5 This application provides a high-safety thermal cutting device, including a thermal cutting device 10 and a protective cover. The thermal cutting device 10 is mounted on a cutting platform 1. The protective cover includes a fixed protective cover 7 and a movable protective cover 9. Both the fixed protective cover 7 and the movable protective cover 9 include a semi-circular shell and a top plate fixed to the upper end of the shell. The fixed protective cover 7 is mounted on the cutting platform 1. The movable protective cover 9 is rotatably mounted inside the fixed protective cover 7. After the movable protective cover 9 rotates 180° around the axis of the fixed protective cover 7, it and the fixed protective cover 7 together cover the thermal cutting device 10.
[0029] In this application, the protective cover is installed on the cutting platform 1. Since both the fixed protective cover 7 and the movable protective cover 9 have a semi-circular shell structure, and the movable protective cover 9 is rotatably installed inside the fixed protective cover 7, after the movable protective cover 9 rotates 180° around the axis of the fixed protective cover 7, the movable protective cover 9 and the fixed protective cover 7 form a cylindrical structure. This structure is closed in the circumference and at the top, and open at the bottom. The movable protective cover 9 and the fixed protective cover 7 together cover the thermal cutting equipment 10.
[0030] During use, the movable protective cover 9 is rotated to retract into the fixed protective cover 7, opening the protective cover and allowing the workpiece to be placed on the cutting platform 1 for thermal cutting via the thermal cutting equipment 10. Before thermal cutting begins, the movable protective cover 9 is rotated at a certain angle to extend it. After rotation, the movable protective cover 9 and the fixed protective cover 7 together cover the thermal cutting equipment 10, thus protecting the workpiece during the thermal cutting process. The protective cover can block molten slag, significantly improving the safety of thermal cutting.
[0031] According to some embodiments of this application, the fixed protective cover 7 is rotatably disposed on the cutting platform 1, and the fixed protective cover 7 rotates about its axis.
[0032] Since the fixed protective cover 7 is rotatable, after processing is completed, the movable protective cover 9 can be rotated to be retracted into the fixed protective cover 7, and then the fixed protective cover 7 can be rotated to make the entire protective cover rotate. This makes it easy to adjust the opening position of the protective cover, thus making it easy to remove the workpiece from the top surface of the cutting platform 1.
[0033] According to some embodiments of this application, an annular limiting plate 2 is fixedly provided on the cutting platform 1, and an annular rotating plate 3 is rotatably installed on the inner side of the annular limiting plate 2. The top surface of the annular rotating plate 3 is fixedly connected to the lower end of the fixed protective cover 7.
[0034] By setting an annular limiting plate 2 on the top surface of the cutting platform 1, the annular limiting plate 2 serves as a rotation limiting component for the annular rotating plate 3. The annular rotating plate 3 is rotatably mounted on the annular limiting plate 2, and the fixed protective cover 7 is fixedly connected to the annular rotating plate 3. In this way, the fixed protective cover 7 can be rotated by driving the annular rotating plate 3 to rotate.
[0035] According to some embodiments of this application, a driving member is also included for driving the annular rotating plate 3 to rotate. The driving member is connected to the annular rotating plate 3 in a transmission manner, thereby driving the annular rotating plate 3 to rotate.
[0036] According to some embodiments of this application, the driving component includes a first motor 5, a gear 6 is provided on the output shaft of the first motor 5, and the annular rotating plate 3 is provided with gear teeth 4 that mesh with the gear 6. The first motor 5 drives the gear 6 to rotate, and the annular rotating plate 3 rotates by the meshing of the gear 6 with the gear teeth 4 on the annular rotating plate 3.
[0037] Of course, other structural methods can also be used to drive the annular rotating plate 3 to rotate, such as using worm gears, belt drives, etc.

[0039] According to some embodiments of this application, a second motor 8 is provided at the upper end of the fixed protective cover 7, and the output shaft of the second motor 8 passes through the fixed protective cover 7 and is connected to the movable protective cover 9. The second motor 8 can drive the movable protective cover 9 to rotate, thereby realizing the opening and closing of the protective cover.
[0040] According to some embodiments of this application, a protective film 11 for shading light is adhered to the outer side of the fixed protective cover 7, which can improve the strong light radiation during thermal cutting.
[0041] According to some embodiments of this application, a protective film 11 for shading light is adhered to the outer side of the dynamic protective cover 9, which can improve the strong light radiation during thermal cutting.
[0042] According to some embodiments of this application, the protective film 11 is a dark-colored light-blocking film. By using a dark-colored light-blocking film, a large amount of light can be absorbed and blocked, preventing the strong light generated during cutting from damaging the operator's eyes.
[0043] The specific working principle of this application is as follows: During use, the workpiece is placed on the cutting platform 1, and thermal cutting is performed by the thermal cutting equipment 10. Before cutting, the second motor 8 is turned on, and the second motor 8 drives the moving protective cover 9 to rotate at a certain angle. After rotation, the moving protective cover 9 and the fixed protective cover 7 together cover the thermal cutting equipment 10, thereby covering the workpiece during the thermal cutting process. The protective film 11 on the surface of the protective cover can effectively block light, and the protective cover can also block molten slag, which greatly improves the safety of thermal cutting.
[0044] After processing is completed, the second motor 8 is turned on to drive the moving protective cover 9 to rotate inside the fixed protective cover 7. The first motor 5 is turned on to drive the gear 6 to rotate. The gear teeth 4 can drive the annular rotating plate 3 to rotate as a whole.
