DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-7 In an embodiment of the present invention, a cleaning device for removing surface oxides during ring rolling by using high-pressure jetting comprises: The machine body 100, a clamping mechanism 200 for cleaning oxides on the inner and outer walls of the ring body, a scraping mechanism 300 for cleaning oxides on the top surface of the ring body, and a supporting mechanism 400 for supporting the ring body and cleaning the bottom surface of the ring body. The clamping mechanism 200 is located inside the machine body 100. The clamping mechanism 200 includes a sliding frame 210, and two sliders 220 are slidably clamped inside the sliding frame 210. The top surfaces of the two sliders 220 are provided with rotating holes, and the insides of the two rotating holes are rotatably sleeved with tube bodies 230. The top ends of the two tube bodies 230 are rotatably connected to collection pipes, and the bottom ends are rotatably connected to connecting tubes 231. The insides of the two connecting tubes 231 are fixedly sleeved with air intake pipes. The outer walls of the two tube bodies 230 are provided with multiple jet nozzles 233, and the outer walls of the two tube bodies 230 are fixedly connected with multiple burrs 232. The scraping mechanism 300 is slidably clamped with the clamping mechanism 200, and the supporting mechanism 400 is fixedly connected with the scraping mechanism 300.

[0020] Specifically, the machine body 100 is an existing horizontal ring rolling machine. When the machine body 100 performs the ring rolling operation, the two connecting tubes 231 can be connected to the air intake pipe, and the two air intake pipes are connected to the air storage tank. The air storage tank contains high-pressure gas. The high-pressure gas enters the two tube bodies 230 through the air intake pipe and is discharged from the two collecting pipes. The high-pressure gas inside the tube body 230 can be partially ejected to the outside through multiple jet ports 233. Since the amount of high-pressure gas entering the air intake pipe is large, and the jet port 233 is smaller than the diameter of the collecting pipe, most of the high-pressure gas inside the tube body 230 flows to be discharged from the collecting pipe. Then, the annular workpiece is placed on the machine body 100 and supported by the supporting mechanism 400. Then, the annular workpiece is clamped by the two tube bodies 230, so that the two tube bodies 230 are respectively attached to the inner wall and the outer wall of the annular workpiece, and then the machine body 100 is started. The annular workpiece is driven to rotate. During the rotation of the annular workpiece, the two tube bodies 230 can be rotated so that the two tube bodies 230 can use the thorns 232 to rub the oxides on the outer and inner walls of the annular workpiece. The thorns 232 on the tube body 230 can be densely arranged as needed, so that the thorns 232 form a state similar to a steel brush. When the tube body 230 rotates, the thorns 232 can scrape the oxides on the outer and inner walls of the annular workpiece to break and peel off the oxides, and the broken oxides can be impacted by the high-pressure gas ejected from the jet 233 on the tube body 230. When the annular workpiece becomes larger through the ring rolling process, the two tube bodies 230 can be always attached to the inner and outer walls of the annular workpiece by moving the slide frame 210, thereby improving the cleaning effect of the oxides on the surface of the annular workpiece, and the oxides on the surface of the annular workpiece can be cleaned during the whole ring rolling process.

[0023] In this embodiment, the two sliders 220 are initially pressed together under the drive of the adjacent rebound springs 221. When the annular workpiece needs to be clamped, the two sliders 220 can be manually pulled apart by a tool and then clamped onto the annular workpiece, so that the two tubes 230 can always be pressed against the outer wall and the inner wall of the annular workpiece. Then, when the annular workpiece is driven by the machine body 100 to roll the ring, the two driving motors can be started to drive the adjacent gears 240 to rotate, so that the two gears 240 drive the adjacent tubes 230 to rotate synchronously through the gear ring 235, so that the rotation direction of the tubes 230 is consistent with the rotation direction of the annular workpiece. In the opposite direction, when the tube body 230 rotates, the oxides on the outer and inner walls of the annular workpiece can be pre-crushed by the thorns 232, and then the scraper 234 scrapes the crushed oxides on the outer and inner walls of the annular workpiece, and the high-pressure gas ejected from the jet port 233 impacts the crushed oxides, thereby improving the cleaning effect of the oxides on the outer and inner walls of the annular workpiece, and the scraper 234 may scrape part of the oxides into the interior of the tube body 230 through the jet port 233, and the oxides scraped into the interior of the tube body 230 can be discharged through the collecting pipe by the high-pressure gas flowing through the interior of the tube body 230.

[0024] like Figure 2 and Figure 5 As shown, in this embodiment, the scraping mechanism 300 includes: Two guide rails 310, a movable plate 320 and two power boxes 330, the bottom ends of the two guide rails 310 are fixedly connected to the supporting mechanism 400, the top surface of the movable plate 320 is provided with a card slot, and the two ends of the movable plate 320 are respectively slidably connected to the inside of the two guide rails 310, the bottom surfaces of the two U-shaped plates are fixedly connected with card blocks, and the two card blocks are slidably connected to the inside of the card slots, a movable slot is provided on one side of the movable plate 320, a card strip is provided on one side of the slide frame 210, and the card strip is slidably connected to the inside of the movable slot, and the bottom of the movable plate 320 A plurality of scrapers 321 are fixedly connected to the surface, two power boxes 330 are respectively fixedly connected to the top ends of the two guide rails 310, power motors are arranged inside the two power boxes 330, the top surfaces of the two guide rails 310 are rotatably connected with adjusting screws 331, and the top ends of the two adjusting screws 331 are fixedly connected to the motor shafts of adjacent power motors, threaded holes are provided at both ends of the movable plate 320, and the inner side walls of the two threaded holes are respectively screwed with the outer side walls of the two adjusting screws 331, and any scraper 321 is arranged at an angle.

[0025] In specific implementation, after the annular workpiece is placed on the machine body 100 and supported by the supporting mechanism 400, the two power motors can be started to drive the two adjusting screws 331 to rotate to drive the movable plate 320 to move downward, so that the movable plate 320 is pressed on the top of the annular workpiece, and multiple scrapers 321 are in contact with the top surface of the annular workpiece. When the annular workpiece is deformed by the ring rolling, the deformed annular workpiece can drive the slide frame 210 to slide along the moving groove through the abutting tube body 230, so that the two tube bodies 230 are always in contact with the annular workpiece, and the two power motors can be started to drive the movable plate 320 to move, so that multiple scrapers 321 are always in contact with the top of the annular workpiece. The scraper 321 is made of spring steel sheet, has a certain elasticity, and is arranged at an angle, so that when the movable plate 320 moves downward, the scraper 321 can be slightly pressed on the top surface of the annular workpiece through its own elasticity to keep it always in contact, and then when the annular workpiece rotates, the scraper 321 can scrape and clean the oxide on the top surface of the annular workpiece.

A screw-in hole is opened on one side of any clamping block, and the inner side wall of any screw-in hole is screwed with the outer side wall of the adjacent bidirectional screw 421.

[0027] In specific implementation, the annular workpiece can be placed on the two support plates 430 and supported by the two support plates 430. When the annular workpiece is deformed and increased after ring rolling, the two servo motors can be started to drive the adjacent main screws 411 to rotate, and the positions of the two slide rails 420 can be adjusted by the main screws 411. The two bidirectional screws 421 can be driven to rotate by starting two stepping motors. When any bidirectional screw 421 rotates, it can drive the adjacent two clamping blocks to move toward or away from each other, thereby adjusting the positions of the two slide rails 420. The rod 421 and the clamping block drive the two support plates 430 to move synchronously toward or away from each other, so that the two support plates 430 can always support the annular workpiece when the annular workpiece is deformed and increased through ring rolling, and by moving the two support plates 430 below the annular workpiece, one support plate 430 can synchronously drive the positions of the clamping mechanism 200 and the scraping mechanism 300 on the annular workpiece, so that the clamping mechanism 200, the scraping mechanism 300 and the supporting mechanism 400 are not easy to affect the ring rolling operation of the machine body 100 on the annular workpiece.
