[0002] As the number of scrapped cars continues to increase, the dismantling and recycling of scrapped cars are receiving more and more attention. After the scrapped cars enter the scrapping enterprise site, the enterprise will dismantle them as soon as possible to avoid occupying the site. The dismantling process ranges from overall cutting to subsequent fine dismantling, and a cutting saw is required to dismantle the car.

[0003] Existing cutting saws rely solely on natural heat dissipation or simple air cooling, such as allowing air to flow naturally through the blade to dissipate heat during the cutting process. When replacing the blade, it is usually necessary to use a tool such as a wrench to loosen the bolts or nuts that fix the blade, then remove the old blade, install the new blade, and tighten the fixings. During the cutting process, the debris generated lacks an effective collection device and is simply scattered naturally around the work area.

[0004] The existing device has limited cooling effect and cannot effectively reduce the temperature of the blade during high-intensity cutting work, which easily leads to overheating of the blade, reducing the service life and cutting quality. The entire process of replacing the blade is complicated and time-consuming, affecting work efficiency, and there may be safety hazards during the replacement process. The debris generated not only makes the work area messy and affects the cleanliness of the working environment, but also increases the difficulty and time cost of subsequent cleaning work. In response to the above problems, a cutting saw for dismantling scrapped cars is proposed. Utility Model Content

[0038] Working principle: When in use, turn on the first motor 23, the output end of the first motor 23 drives the turntable 9 to rotate, turn on the second hydraulic cylinder 8, the second hydraulic cylinder 8 drives the second piston rod 7, thereby driving the lifting of the fixed plate 6, the first fixed frame 2 and the bracket 1, and then driving the third fixed frame 21, turn on the first hydraulic cylinder 4, the first hydraulic cylinder 4 drives the first piston rod 3 to adjust the angle of the bracket 1 and the third fixed frame 21, turn on the second motor 33, the second motor 33 drives the second bevel gear 32, thereby driving the first bevel gear 31, and then driving the fixed rod 30, so that the cutting blade 17 rotates, and the scrapped car is dismantled and cut. During the operation, the cutting blade 17 generates heat, and the valve 19 is opened. The compressed air in the storage tank 20 enters the vortex through the pipe 43. A high-speed rotating vortex is formed in the flow chamber 18. Due to the action of centrifugal force, the gas is divided into two parts. The heavier gas molecules are pushed to the outside of the vortex chamber 18, and the lighter gas molecules gather toward the center. Due to friction and collision, the air molecules produce energy separation, and the high-temperature gas is discharged from the hot end tube 26, and the low-temperature gas is discharged from the cold end tube 25, and the low-temperature gas is blown to the cutting blade 17. If the cutting blade 17 is worn and needs to be replaced, press the button 16, the button 16 squeezes the spring 40 and the second pull rod 39, the second pull rod 39 drives the second baffle 42 to drive the first pull rod 37, the first pull rod 37 squeezes the disc spring 38, and the first pull rod 37 drives the fixing clamp 34 to move. When the fixing clamp 34 moves out of the housing 36, the steel ball 35 loosens, and the fixing rod 30 is disassembled, so that the cutting blade 17 can be replaced. A lock hole is opened in the fixing clamp 34 to prevent the steel ball 35 from loosening. After the cutting blade 17 is replaced, the fixing rod 30 is inserted into the fixing clamp 34, and the button 16 is released. The disc spring 38 drives the first pull rod 37 and the second baffle 42 to reset. The spring 40 drives the second pull rod 39 to reset. When the first pull rod 37 is reset, it drives the fixing clamp 34. The inner wall of the shell 36 squeezes the steel ball 35, so that the steel ball 35 and the lock hole on the fixing rod 30 are fixed. When the cutting blade 17 is worn or damaged, it can be quickly replaced, avoiding work stagnation caused by waiting for the cutting blade 17 to be replaced, ensuring the continuity of the disassembly work, reducing the time spent on replacing the cutting blade 17, and being able to dismantle the scrapped car more quickly. Cutting discs 17 of different specifications can be switched to meet the cutting requirements of different parts, thereby speeding up the dismantling progress of scrapped cars as a whole. When facing different types of scrapped cars and different cutting tasks, the appropriate cutting disc 17 can be quickly selected for replacement according to actual conditions, thereby improving the adaptability and flexibility of the cutting saw. Cooling the blade can effectively reduce the working temperature of the cutting disc 17, reduce thermal damage, and thus extend the service life of the cutting disc 17. A stable low-temperature environment can maintain the hardness and sharpness of the cutting disc 17, making the cutting process smoother, reducing the shaking and deformation of the cutting disc 17, and thus improving the cutting accuracy and quality. During cutting, debris is generated, and the fan 12 is turned on, and the fan 12 sucks the debris into the collection box 22 through the collection pipe 24.The filter 27 prevents debris from entering the fan 12 and damaging it. When there is too much debris, the handle 14 is used to open the door 13 to handle the debris, preventing it from being scattered everywhere, making the work area cleaner and tidier, reducing the difficulty and time of subsequent cleaning work, improving work efficiency, reducing the splashing of debris, and lowering the risk of accidental injury. After the debris is collected, it can be conveniently centralized for processing and recycling, reducing the impact of the debris on the cutting blade 17 and extending the service life of the cutting blade 17.
