[0002] Flame cutting machine, also known as flame CNC cutting machine, is a CNC machine that uses flame cutting. It uses the heat energy generated by the combustion of oxygen and fuel gas (acetylene, propane, liquefied gas, etc.) to preheat the cutting part of the workpiece to the ignition point of the metal, and then sprays a high-speed cutting oxygen flow to make the preheated metal burn and release heat to preheat the rear metal to be cut, thereby achieving cutting. It is mainly used in heavy industry.

[0003] Existing flame cutting machines will generate a large number of high-temperature metal sparks during cutting operations. The metal sparks will splash and easily burn the workers.

[0022] Motors 9 are fixedly installed at the upper parts of the two mounting grooves 6 in the frame 1. The output ends of the two motors 9 are fixedly installed on the corresponding threaded rods 7 respectively. The rotation of the threaded rods 7 by the motors 9 is beneficial to the use of the device. Cylinders 15 are fixedly installed at the front and rear parts of the motors 9 on the left side of the frame 1. Push plates 14 are fixedly installed on the output ends of the two cylinders 15. The right side of the push plate 14 is fixedly installed on the bracket 11. The push plate 14 is driven to move left and right by the cylinders 15, which is beneficial to the use of the device. A collecting tank 20 is provided at the lower part of the guide groove 10 in the frame 1. The waste chips generated during the cutting process can be collected through the collecting trough 20. A cleaning door 4 is connected to the collecting trough 20 at the front end of the frame 1 through a hinge. A negative pressure fan 5 is fixedly installed in the cleaning door 4. A filter 19 is fixedly installed at the rear end of the cleaning door 4 corresponding to the negative pressure fan 5.

[0023] Working principle: When in use, the workpiece to be cut can be placed on the bracket 11, and then the switch of the motor 9 is turned on. The motor 9 works to drive the threaded rod 7 to rotate. At this time, the lifting frame 8 drives the two protective plates 16 to rise, so as to shield the flame cutting gun 13 and the bracket 11. Then, the flame cutting gun 13 can be used for cutting. The cutting operation can be checked through the visual window 18. The shading film 17 can prevent the dazzling light generated during the cutting process from hurting the eyes of the staff. After the cutting process, the protective plate 16 is lowered and reset using the above principle, and then the cut workpiece is taken out, and the protective plate 16 is raised again. At this time, the cleaning switch is turned on, and the output end of the cylinder 15 drives the push plate 14 and the bracket 11 to slide back and forth on the slide rod 12, so that the waste chips generated during the cutting process can be shaken off. At the same time, the negative pressure fan 5 works to generate negative pressure at the guide groove 10, thereby sucking in the waste chips. This highly safe flame cutting machine is easy to use. Through the above components, the waste chips generated during the cutting process can be prevented from scalding the staff and the dazzling strong light can be avoided from hurting the eyes of the staff, thereby further improving the safety of the use of the equipment. At the same time, the waste chips on the frame 1 can be automatically cleaned after cutting, thereby further improving the convenience of use.
