[0016] The present invention adopts the above technical solution to bring the following beneficial effects: 1. This automobile radiator aluminum tube cutting machine, after the first electric push rod is started, pushes the push block to move on the inner wall of the frame, and transmits the linear motion to the moving rod through the rolling of the ball in the rolling groove, thereby driving the clamping plate to move closer to the aluminum tube. The design of the moving rod tilting 45 degrees, no matter how the diameter of the aluminum tube changes, the clamping plate can be in close contact with the farthest points on both sides of the aluminum tube to achieve stable clamping. After the aluminum tube contacts the extended end of the airbag, the airbag will expand adaptively and fit the outer wall of the aluminum tube in all directions, greatly increasing the contact area, evenly dispersing the clamping force, and effectively avoiding the shaking and displacement of the aluminum tube due to local uneven force during the cutting process.

[0017] 2. This automobile radiator aluminum tube cutting machine, by setting a telescopic rod, a spring, a hinge block, an arc plate and a roller body, cooperates with a placement table during cutting to fix the aluminum tube from the top and bottom, greatly enhancing the stability of the aluminum tube during the cutting process and effectively preventing the shaking of the aluminum tube from affecting the cutting effect.

[0018] 3. The aluminum tube cutting machine for automobile radiators drives the cutting knife to descend through the second electric push rod to cut the aluminum tube. The grinding discs on both sides of the cutting knife grind the cut surface of the aluminum tube at the moment of cutting, timely removing the burrs on the cut surface, making the incision smooth and flat, greatly improving the cutting quality of the aluminum tube, reducing the subsequent cumbersome grinding process, and lowering the processing cost.

[0019] 4. The aluminum tube cutting machine for automobile radiators drives the first rotating rod to rotate through the second motor. After the efficient transmission of the gear set, the second rotating rod drives the rotating roller to rotate synchronously, making the aluminum tube rotate at a constant speed during cutting. The rotation of the aluminum tube makes the contact between the cutting knife and the aluminum tube more uniform, the cutting process becomes smoother, and the cutting efficiency is significantly improved. Moreover, the rotation of the aluminum tube can also effectively reduce the stroke of the cutting knife, avoid applying too much pressure on the aluminum tube due to the too long stroke of the cutting knife, reduce the risk of aluminum tube deformation, and further ensure the cutting accuracy and the quality of the aluminum tube.

[0020] 5. The aluminum tube cutting machine for automobile radiators can not only quickly cool the cutting area by using the coolant in the water tank through the cleaning sponge block, reduce the temperature of the cutting area, reduce the influence of thermal deformation on the aluminum tube and the cutting knife, and extend the service life of the cutting knife, but also timely adsorb and remove the impurities on the surface of the aluminum tube, keep the cutting area clean. The surrounding groove on the first rotating rod cooperates with the connecting block to drive the second moving block to reciprocate at the bottom of the water tank, so that the scraping blade can regularly scrape off the impurities accumulated on the cleaning sponge block, ensuring that the cleaning sponge block always maintains good cleaning and cooling performance.

The rotating roller 907 is fixedly sleeved on the second rotating rod 906. The second rotating rod 906 is transmission-connected to the first rotating rod 904 through a gear set. A cleaning sponge block 908 is fixedly sleeved on the outer wall of the second rotating rod 906, and the cleaning sponge block 908 is located directly below the cutter 803. A surrounding groove 909 is opened on the first rotating rod 904.

The top of the placing table 901 is set in an arc shape, and the top of the rotating roller 907 is higher than the arc surface of the placing table 901.

[0030] Working principle: Pour the coolant into the water tank 902 so that the coolant exceeds the bottom of the cleaning sponge block 908. Place the aluminum tube on the placing table 901, with the bottom of the aluminum tube contacting the top of the rotating roller 907, and one end of the aluminum tube contacting the push plate 5. By starting the first electric push rod 702, the first electric push rod 702 drives the push block 703 to move on the inner wall of the frame 701, thereby pushing the ball 704 to roll in the rolling groove, and then driving the moving rod 705 to move, so that the clamping plate 706 contacts the aluminum tube. At this time, the aluminum tube will first contact the extension end of the airbag 707, and squeeze the airbag 707 through the extension end, so that all the extension ends of the airbag 707 contact the outer wall of the aluminum tube, thereby fixing the aluminum tube. After the fixing is completed, by starting the second electric push rod 801, the second electric push rod 801 drives the lifting plate 802 to descend. At this time, the roller 810 on the arc plate 809 first contacts the top of the aluminum tube, and then fixes the top of the aluminum tube. When the lifting plate 802 continues to descend, the pipe is cut by the cutter 803. At the same time, the second motor 903 is started, and the second motor 903 drives the first rotating rod 904 to rotate, thereby driving the second rotating rod 906 to rotate through the gear set. The rotation of the second rotating rod 906 drives the rotating roller 907 to rotate. With the cooperation of the roller 810, the aluminum tube is driven to rotate, so that the aluminum tube is cut more thoroughly, which can effectively reduce the stroke of the cutter 803 and reduce the deformation of the aluminum tube. When the second rotating rod 906 rotates, it drives the cleaning sponge block 908 to rotate. The cutting part is cooled by the cleaning sponge block 908, and the impurities on the aluminum tube are removed. The rotation of the first rotating rod 904 drives the second moving block 910 to reciprocate through the surrounding groove 909 and the connecting block 911, so that the impurities adhered to the cleaning sponge block 908 are scraped off by the scraping blade 912. After the aluminum tube is cut off, the grinding piece 804 on the side of the cutter 803 grinds the cutting surface of the aluminum tube to facilitate subsequent processing. After the cutting is completed, the second electric push rod 801 drives the cutter 803 to rise, and the first electric push rod 702 drives the push block 703 to move backward, driving the moving rod 705 to move through the connecting rope 709, thereby loosening the aluminum tube. By starting the first motor 2, the reciprocating lead screw 3 is rotated, so that the push plate 5 is driven to move to the left by the first moving block 4, and then the aluminum tube is driven to move to the left for the next cutting.

[0031] The present invention provides an aluminum tube cutting machine for automobile radiators. There are many methods and ways to specifically implement this technical solution. The above description is only the preferred embodiment of the present invention.
