[0037] By setting the turnover assembly 6, the operator needs to cut the metal plate or metal frame through the lifting equipment in the drawing before cutting the cutting part. The edge of the workpiece to be cut is clamped and fixed by using the clamping pressure plate 68 to avoid the sliding deviation of the workpiece to be cut during cutting.

[0041] By setting up the flue gas collecting assembly 8, during the cutting process, the operator controls the self-suction pump 88 through the control module 3, the self-suction pump 88 sucks the dust and impurities from the dust hood 89 and the collecting pool 81 through the pipeline, the dust hood 89 absorbs part of the smoke and impurities generated in the process of machining the gas cutting machine body 10, the smoke and impurities enter the pipeline from the dust hood 89 into the filter box 810 and contact the activated carbon filter layer 811, filter the smoke and impurities in the air, and the filtered air is discharged through the pipeline on one side of the filter box 810, at the same time, another part of the smoke and impurities generated in the process of machining the gas cutting machine body 10 will fall through the gap generated by cutting to the bottom end of the turnover platform 2, and be sucked by the self-suction pump 88 through the collecting pool 81, after passing through the support plate 82 at the end of the collecting pool 81, the dust and impurities pass through the pipeline at the bottom end of the collecting pool 81 into the filter box 810 through the self-suction pump 88, and the air is filtered through the activated carbon filter layer 811 after passing through the dust and impurities, and is discharged through the pipeline on one side of the filter box 810, in the process of suction of the self-suction pump 88, the negative pressure air flow will drive the installed vortex fan 84 on the mounting frame two 83 to rotate, the heat-resistant ropes 85 on both sides of the rotating shaft of the vortex fan 84 can improve the inertia of the swing through the weight of the counterweight block 86 itself in rotation, and a plurality of heat-resistant blocks 87 outside the heat-resistant ropes 85 can hit the metal hot particles contained in the dust and impurities in the process of swinging of the heat-resistant ropes 85, effectively avoiding the metal impurities in the air from depositing at the bottom end of the collecting pool 81 or being adsorbed on the inner wall of the collecting pool 81 in the process of suction of the self-suction pump 88, so as to ensure the cleanliness inside the collecting pool 81, avoid the bottom end of the collecting pool 81 and the pipeline connection port from being blocked, and the support plate 82 is used to avoid the direct contact of the large cutting flame tail flame with the inner side of the collecting pool 81 to cause damage,

[0042] The working principle of the technical scheme provided by the application is as follows:

[0043] Before cutting the cutting piece, the operator lifts the metal plate or metal frame to be cut to the top of the machining platform 62 through hoisting equipment not marked in the figure, clamps and fixes the edge of the cutting workpiece by using the clamping pressure plate 68, so as to avoid the sliding deviation of the cutting workpiece in the cutting process, because the inner side of the clamping pressure plate 68 is provided with a non-slip gasket, the non-slip gasket can increase the friction force with the surface of the workpiece in the clamping process, effectively reducing the fine vibration of the workpiece in the cutting process, the machining size data is sent to the sliding module 4 through the control module 3, the sliding module 4 slides on one side of the turnover platform 2, and the gas cutting machine body 10 can be machined on the surface of the cutting piece through the extension and retraction of the air cylinder 9.

[0044] When cutting a large-volume steel component or steel plate, the operator can control the two drive motors 67 to rotate through the control module 3, which drives the screw rods 66 to rotate, and the two screw rods 66 are in threaded engagement with the threaded holes in the inner side of the sliding mounting block 65 through synchronous rotation, thereby driving the sliding mounting block 65 to move outside the two screw rods 66, and the sliding of the sliding mounting block 65 drives the two connecting plates 64 to rotate outside the sliding mounting block 65, while the other end of the two connecting plates 64 provides support force for the rotation of the mounting seat 63 and the overturning platform 2 on one side of the mounting frame 61 through rotation on both sides of the mounting seat 63, thereby realizing the stable overturning movement of the overturning platform 2. During the overturning process, the operator can adjust the speed and direction of the drive motor 67 through the control module 3, thereby accurately controlling the overturning angle and speed of the overturning platform 2 and the workpiece to be cut, ensuring the safety and stability of the overturning process, so that the device can cut large-volume steel components or steel plates when the gas cylinder 9 pushes the gas cutter body 10 to move, thereby enabling the device to cut and process large-volume steel components or steel plates in a smaller planar space, improving the processing types of the device, enabling the gas cutter body 10 to realize efficient cutting action in a limited space, and improving space utilization;

[0045] During the overturning process of the overturning platform 2, the first bevel gear set 71 meshes and rotates at the rotating shaft end of the overturning platform 2, and one of the bevel gears in the first bevel gear set 71 drives the telescopic rod 72 to rotate, so that the second bevel gear set 73 connected to one end of the telescopic rod 72 follows the rotation. The telescopic function of the telescopic rod 72 can always ensure the stability of the transmission according to the movement distance of the sliding module 4, and at the same time, one of the bevel gears in the second bevel gear set 73 meshes with the bevel gear disc 75, so that the gas cylinder 9 and the gas cutter body 10 can always rotate synchronously with the rotation of the overturning platform 2 during the rotation of the overturning platform 2, ensuring that the gas cutter body 10 always maintains the correct cutting posture and position during the overturning process of the overturning platform 2, thereby realizing accurate cutting of large-volume steel components or steel plates;

[0046] In the cutting process, the operator controls the self-suction pump 88 through the control module 3, and the self-suction pump 88 sucks dust and impurities from the dust cover 89 and the collection tank 81 through the pipeline. The dust cover 89 absorbs part of the smoke and impurities generated during the processing of the gas cutting machine body 10, and the smoke and impurities enter the pipeline from the dust cover 89 and contact the activated carbon filter layer 811 in the filter box 810 to filter the smoke and impurities in the air. After the air is filtered, it is discharged through the pipeline on one side of the filter box 810. At the same time, another part of the smoke and impurities generated during the processing of the gas cutting machine body 10 will fall through the gap generated by cutting to the bottom end of the turnover platform 2, which is sucked by the self-suction pump 88 through the collection tank 81. After passing through the support plate 82 at the end of the collection tank 81, the dust and impurities pass through the pipeline at the bottom end of the collection tank 81, enter the filter box 810 through the self-suction pump 88, and the dust and impurities in the air are filtered through the activated carbon filter layer 811 and discharged through the pipeline on one side of the filter box 810. During the suction process of the self-suction pump 88, the negative pressure air flow will drive the installed vortex fan 84 on the mounting frame two 83 to rotate, and the heat-resistant ropes 85 on both sides of the rotating shaft of the vortex fan 84 can improve the inertia of the swing through the weight of the counterweight block 86. A plurality of heat-resistant blocks 87 outside the heat-resistant ropes 85 can hit the metal hot particles contained in the dust and impurities during the swing of the heat-resistant ropes 85, effectively avoiding the deposition of metal impurities in the air on the bottom end of the collection tank 81 or adsorption on the inner wall of the collection tank 81 during the suction process of the self-suction pump 88, thereby ensuring the cleanliness of the inside of the collection tank 81 and avoiding the blockage of the bottom end of the collection tank 81 and the pipeline connection port. At the same time, the support plate 82 is used to avoid direct contact between the large cutting flame tail flame and the inside of the collection tank 81 to cause damage.
