Description

Technical Field

[0001] The invention relates to the technical field of metal sawing, and in particular to an automatic lubrication device for sawing seamless steel pipes. Background Art

[0002] During the cutting process of seamless steel pipes, the saw blade needs to be lubricated regularly to reduce the friction between the side wall of the saw blade and the steel pipe, thereby ensuring that the saw blade is not easily deformed due to excessive temperature during the long-term cutting process. However, the current method of lubricating the saw blade is often to manually use a brush to apply an appropriate amount of lubricant on the side wall of the saw blade. During this process, the machine needs to be stopped. On the one hand, it increases the labor input, and on the other hand, it will increase the time required for cutting and reduce the cutting efficiency.

[0029] like Figure 4 As shown, the air intake mechanism 4 includes a pair of air cylinders 41, a piston rod 42 is sealed and movably connected inside the air cylinder 41, a fixing frame 46 is fixedly connected to the U-shaped frame 3, a rotating shaft 44 is rotatably connected to the fixing frame 46, a pair of turntables 43 are fixedly connected at both ends of the rotating shaft 44, and are respectively used to drive the two piston rods 42 to reciprocate, a driving motor 45 is installed on the fixing frame 46, the rotating shaft of the driving motor 45 is fixedly connected to the driving gear 47, and a driven gear 48 meshing with the driving gear 47 is fixedly connected to the rotating shaft 44; a first air pipe 49 is fixedly connected between the two air cylinders 41, and a one-way air outlet valve 411 is connected between the first air pipe 49 and the air cylinder 41, so that the gas can only enter the first air pipe 49 from the air cylinder 41 , and a pair of air outlet pipes 410 are fixedly connected to the first air pipe 49, the air outlet pipe 410 is made of hose material, and the air outlet pipe 410 is fixedly connected to the atomizing nozzle 7. At the same time, a second air pipe 412 is fixedly connected between the two air cylinders 41, and a one-way air inlet valve 413 is connected between the second air pipe 412 and the air cylinder 41. The gas can only enter the air cylinder 41 from the second air pipe 412, and the second air pipe 412 is connected to the air inlet pipe 414; the driving motor 45 drives the rotating shaft 44 to rotate, drives the two turntables 43 to rotate, and then drives the two piston rods 42 to reciprocate, thereby supplying air to the atomizing nozzle 7, the gas and lubricating oil are mixed in the atomizing nozzle 7, and the liquid is sprayed onto the surface of the saw blade 101 in the form of mist.

[0030] like Figure 5-Figure 6 As shown, in order to adjust the entry mode of the intake mechanism 4, a flip rod 431 is rotatably connected to the center of the turntable 43, one end of the flip rod 431 is rotatably connected to a connecting rod 432, and one end of the connecting rod 432 is rotatably connected to the piston rod 42; and a pair of blocks 433 are symmetrically fixedly connected to the turntable 43, which are used to limit the flip rod 431; an elastic clamping rod 434 is fixedly connected to the block 433, and a clamping block 435 is provided at the end of the clamping rod 434, and a clamping groove 436 cooperating with the clamping block 435 is provided on the flip rod 431, and a pair of clamping grooves 436 are provided, which are convenient for cooperating with the two clamping rods 434 respectively, and the flip rod 431 can be fixed by the cooperation of the clamping rod 434 and the block 433.

[0031] During specific implementation: the driving motor 45 drives the two turntables 43 to rotate. When the flip rods 431 of the two turntables 43 face the same direction, the extended lengths of the two piston rods 42 are the same. When the two turntables 43 rotate at the same time, the two piston rods 42 are driven to move in the same direction, thereby driving the two air cylinders 41 to inhale and exhale air at the same time. When the air cylinder 41 is inhaling air, it is unable to spray the lubricating oil, so that the atomizing nozzle 7 is in an intermittent spraying state; by adjusting the position of the flip rod 431 of one of the turntables 43, the flip rod 431 is rotated 180° to contact the other block 433, and is fixed by the clamping rod 434, so that the two flip rods 431 face opposite directions. At this time, when the two turntables 43 rotate at the same time, the two piston rods 42 are driven to move in opposite directions. One of the two air cylinders 41 is inhaling air and the other is exhaling air, so that there is always an air cylinder 41 supplying air to the atomizing nozzle 7, so that the atomizing nozzle 7 is in a continuous spraying state, which is suitable for high-speed rotation of the saw blade 101.

[0032] Embodiment 2: Based on the structure of the above embodiment 1, Figure 2 and Figure 7 As shown, a recovery box 5 is fixedly connected under the U-shaped frame 3 for recovering the lubricating oil; one end of the air inlet pipe 414 is connected to the recovery box 5; wherein, a filter screen 51 is connected inside the recovery box 5, and the filter screen 51 is used to filter the lubricating oil to prevent impurities from entering the air cylinder 41, and a vertically arranged oil baffle plate 52 is fixedly connected to the recovery box 5, and an oil channel 53 is provided on the oil baffle plate 52. When the saw blade 101 rotates at a high speed, the lubricating oil is thrown into the oil channel 53, and the lubricating oil flows into the recovery box 5 through the oil channel 53; the recovered lubricating oil mixed with gas enters the air cylinder 41 through the air inlet pipe 414, and finally enters the atomizing nozzle 7 through the air outlet pipe 410.

[0033] Preferably, a pair of inclined scraper plates 54 are fixedly connected to the recovery box 5, and the scraper plates 54 are respectively arranged on the two sides of the saw blade 101, and the scraper plates 54 are in contact with the surface of the saw blade 101, and the friction between the two is almost zero. The scraper plates 54 scrape off excess lubricating oil and impurities on the surface of the saw blade 101, and the lubricating oil flows into the recovery box 5 for recovery.

[0034] During specific implementation, after the atomizing nozzle 7 sprays the lubricating oil onto the surface of the saw blade 101, when the saw blade 101 rotates at high speed, the lubricating oil is thrown into the oil channel 53, and the lubricating oil flows into the recovery box 5 through the oil channel 53, and the scraper plate 54 scrapes off the excess lubricating oil and impurities on the surface of the saw blade 101, and the lubricating oil flows into the recovery box 5 along the scraper plate 54; the recovered lubricating oil mixed with gas enters the air cylinder 41 through the air inlet pipe 414, and finally enters the atomizing nozzle 7 through the air outlet pipe 410.
