Description

Technical Field

[0001] The invention relates to the technical field of ring rolling and forging, in particular to a cleaning device for removing surface oxides in the ring rolling process by using high-pressure jetting. Background Art

[0002] The horizontal ring rolling machine is a professional equipment for making ring bodies. It heats the initial ring-shaped workpiece and puts it on the core roller. Then, the main roller drives the ring-shaped workpiece to rotate, and multiple holding rollers hold the ring-shaped workpiece from the side. Then, the high-heat ring-shaped workpiece is shaped by extrusion. The height of the ring-shaped workpiece can be controlled by adding a conical pressing roller to press the ring-shaped workpiece. During the ring rolling operation, the inner diameter and outer diameter of the ring-shaped workpiece can be gradually expanded to the predetermined specifications, and the position of each pressing roller on the machine body can be changed due to CNC adjustment. In order to avoid affecting the machine body, In the industry, when cleaning the oxides on the surface of annular workpieces, high-pressure gas or high-pressure water is generally used to clean the surface of the workpiece by spraying a fan-shaped surface through a descaling nozzle. However, the high-pressure water flow or high-pressure gas mainly relies on the impact force of the water flow or gas to peel off and flush the oxides on the surface of the workpiece, but for some oxides with strong adhesion, it may not be possible to completely remove them, which is inconvenient. In addition, the oxides on the surface of workpieces made of some materials are hard and have strong adhesion. It may be difficult to achieve a good cleaning effect only by relying on the impact of high-pressure water flow or high-pressure gas. Summary of the invention

Specific implementation mode

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figure 1-7 , in the embodiment of the present invention, a cleaning device for removing surface oxides during the ring rolling process by using high-pressure air jet includes:

[0033] The body 100, the clamping mechanism 200 for cleaning the oxides on the inner and outer side walls of the ring, the scraping mechanism 300 for cleaning the oxides on the top surface of the ring, and the supporting mechanism 400 for supporting the ring and cleaning the bottom surface of the ring. The clamping mechanism 200 is located inside the body 100. The clamping mechanism 200 includes a sliding frame 210, and two sliders 220 are slidably clamped inside the sliding frame 210. Rotation holes are opened on the top surfaces of the two sliders 220, and pipe bodies 230 are rotatably sleeved inside the two rotation holes. Collection pipes are rotatably connected to the tops of the two pipe bodies 230, and connecting pipe cylinders 231 are rotatably connected to the bottoms of the two pipe bodies 230. Air inlet pipes are fixedly sleeved inside the two connecting pipe cylinders 231. A plurality of jet orifices 233 are opened on the outer side walls of the two pipe bodies 230, and a plurality of convex thorns 232 are fixedly connected to the outer side walls of the two pipe bodies 230. The scraping mechanism 300 is slidably clamped with the clamping mechanism 200, and the supporting mechanism 400 is fixedly connected to the scraping mechanism 300.

[0034] Specifically, the machine body 100 is an existing horizontal ring rolling machine. When the machine body 100 performs ring rolling operations, two connecting tubes 231 can be connected to the intake pipe, and both intake pipes are connected to the gas storage tank. The gas storage tank stores high-pressure gas. The high-pressure gas enters the interiors of the two tube bodies 230 through the intake pipes and then is discharged from the two collection pipes. Moreover, part of the high-pressure gas inside the tube body 230 can be ejected to the outside through multiple jet ports 233. Since the amount of high-pressure gas entering through the intake pipes is large, and the diameter of the jet ports 233 is smaller than that of the collection pipes, most of the high-pressure gas inside the tube body 230 still flows out from the collection pipes. Then, the ring-shaped workpiece is placed on the machine body 100 and supported by the supporting mechanism 400, and then the ring-shaped workpiece is clamped by the two tube bodies 230, so that the two tube bodies 230 respectively abut against the inner side wall and the outer side wall of the ring-shaped workpiece. Then, the machine body 100 is started to drive the ring-shaped workpiece to rotate. During the rotation of the ring-shaped workpiece, the two tube bodies 230 can be rotated to make the two tube bodies 230 use the protrusions 232 to rub the oxides on the outer side wall and the inner side wall of the ring-shaped workpiece. The protrusions 232 on the tube body 230 can be densely arranged as required, so that the protrusions 232 form a state similar to a steel brush. When the tube body 230 rotates, the protrusions 232 can scrape the oxides on the outer side wall and the inner side wall of the ring-shaped workpiece, causing the oxides to break and peel off. Moreover, the high-pressure gas ejected from the jet ports 233 on the tube body 230 can impact the broken oxides. And when the ring-shaped workpiece becomes larger during the ring rolling process, the two tube bodies 230 can be made to always abut against the inner side wall and the outer side wall of the ring-shaped workpiece by moving the sliding frame 210, thereby improving the cleaning effect on the oxides on the surface of the ring-shaped workpiece, and the oxides on the surface of the ring-shaped workpiece can be cleaned throughout the entire ring rolling process.

[0035] Embodiment 1

[0036] As Figure 3-Figure 4 shown, in this embodiment, a return spring 221 is fixedly connected to the outer ends of the two sliders 220 away from each other, and one end of each of the two return springs 221 is fixedly connected to both ends inside the sliding frame 210. A scraping plate 234 is fixedly connected to the inner side wall of any one of the jet ports 233. Tooth rings 235 are fixedly sleeved on the tops of the outer side walls of the two tube bodies 230. U-shaped plates are fixedly connected to the tops of the two sliders 220, and a rotating shaft is rotatably connected between the two arms of each of the two U-shaped plates. Gears 240 are fixedly sleeved on the outer side walls of the two rotating shafts, and both of the two gears 240 are meshed with the adjacent tooth rings 235. The two U-shaped plates are slidably clamped with the scraping mechanism 300, and driving boxes 241 are fixedly connected to the top surfaces of the two U-shaped plates. Driving motors are arranged inside the two driving boxes 241, and the motor shafts of the two driving motors are fixedly connected to the tops of the adjacent rotating shafts.

[0037] In this embodiment, when in the initial state, the two sliders 220 will be brought close to each other under the drive of the adjacent resilient springs 221. When clamping a ring-shaped workpiece, the two sliders 220 can be manually separated by using a tool and then clamped onto the ring-shaped workpiece, so that the two pipe bodies 230 can always be in contact with the outer wall and the inner wall of the ring-shaped workpiece. Then, when the ring-shaped workpiece is driven by the machine body 100 to perform ring rolling, the two drive motors can be started to drive the adjacent gears 240 to rotate, so that the two gears 240 drive the adjacent pipe bodies 230 to rotate synchronously through the toothed ring 235, and the rotation direction of the pipe bodies 230 is opposite to that of the ring-shaped workpiece. When the pipe bodies 230 rotate, the oxides on the outer wall and the inner wall of the ring-shaped workpiece can be broken by the barbs 232 in advance, and then the scraper 234 scrapes the broken oxides on the outer wall and the inner wall of the ring-shaped workpiece, and cooperates with the high-pressure gas ejected from the air jet port 233 to impact the broken oxides, so as to improve the cleaning effect of the oxides on the outer wall and the inner wall of the ring-shaped workpiece. Part of the oxides may be scraped into the interior of the pipe body 230 by the scraper 234 through the air jet port 233, and the oxides scraped into the interior of the pipe body 230 can be discharged through the collecting pipe by the high-pressure gas flowing through the interior of the pipe body 230.

[0038] As Figure 2 and Figure 5 shown, in this embodiment, the scraping mechanism 300 includes:

[0039] Two guide rails 310, a moving plate 320 and two power boxes 330. The bottom ends of the two guide rails 310 are fixedly connected to the supporting mechanism 400. A clamping groove is formed on the top surface of the moving plate 320, and the two ends of the moving plate 320 are respectively slidably clamped inside the two guide rails 310. The bottom surfaces of the two U-shaped plates are fixedly connected with clamping blocks, and the two clamping blocks are respectively slidably clamped inside the clamping groove. A moving groove is formed on one side of the moving plate 320, a clamping bar is formed on one side of the sliding frame 210, and the clamping bar is slidably clamped inside the moving groove. A plurality of scrapers 321 are fixedly connected to the bottom surface of the moving plate 320. The 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 inner top surfaces of the two guide rails 310 are respectively rotatably connected with adjusting screws 331, and the top ends of the two adjusting screws 331 are respectively fixedly connected to the motor shafts of the adjacent power motors. Threaded holes are formed at both ends of the moving 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. Any one of the scrapers 321 is arranged obliquely.

[0040] During specific implementation, after the ring-shaped 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, thereby driving the moving plate 320 to move downward, pressing the moving plate 320 against the top of the ring-shaped workpiece, and making the multiple scraping blades 321 abut against the top surface of the ring-shaped workpiece. When the ring-shaped workpiece undergoes ring rolling deformation, the deformed ring-shaped workpiece can drive the sliding frame 210 to slide along the moving groove through the abutting pipe body 230, so that the two pipe bodies 230 always abut against the ring-shaped workpiece. Moreover, the two power motors can be cooperatively started to drive the moving plate 320 to move, so that the multiple scraping blades 321 always abut against the top of the ring-shaped workpiece. The scraping blades 321 are made of spring steel sheets, have a certain elasticity, and are arranged obliquely, so that the scraping blades 321 can slightly press against the top surface of the ring-shaped workpiece through their own elasticity when the moving plate 320 moves downward to maintain continuous abutment. Then, when the ring-shaped workpiece rotates, the scraping blades 321 can scrape and clean the oxides on the top surface of the ring-shaped workpiece.

[0041] As Figure 2 and Figure 6 shown, in this embodiment, the supporting mechanism 400 includes:

[0042] Two frames 410, two slide rails 420, and two support plates 430. The two frames 410 are respectively located on the opposite sides of the machine body 100. The main screws 411 are rotatably connected between the two ends inside the two frames 410. One side of the two adjacent frames 410 is fixedly connected to the machine body 100. One end of each of the two frames 410 is fixedly connected to a motor box 412, and servo motors are arranged inside the two motor boxes 412. The motor shafts of the two servo motors are fixedly connected to one end of the adjacent main screw 411. The two slide rails 420 are respectively located inside the two frames 410. The bottom surfaces of the two slide rails 420 are fixedly connected with internal thread rings, and the inner side walls of the two internal thread rings are screwed with the outer side walls of the adjacent main screws 411. The bottom surfaces of the two support plates 430 are fixedly connected with two clamping blocks. The two clamping blocks located on the same support plate 430 are respectively slidably clamped inside the two slide rails 420. The bottom ends of the two guide rails 310 are fixedly connected to both ends of one support plate 430. A bidirectional screw 421 is rotatably connected between the two ends inside any one of the slide rails 420. Any bidirectional screw 421 is a positive and negative thread screw. One end of any one of the slide rails 420 is fixedly connected to a connection box 422, and stepping motors are arranged inside the two connection boxes 422. The motor shafts of the two stepping motors are fixedly connected to one end of the adjacent bidirectional screw 421. A screwing hole is formed on one side of any one of the clamping blocks, and the inner side wall of any one of the screwing holes is screwed with the outer side wall of the adjacent bidirectional screw 421.

[0043] During specific implementation, the annular workpiece can be placed above two pallets 430 and supported by the two pallets 430. When the annular workpiece deforms and increases in size after ring rolling, two servo motors can be started to drive the adjacent main screws 411 to rotate. The positions of the two slide rails 420 can be adjusted through the main screws 411, and two stepping motors can be started to drive the two bidirectional screws 421 to rotate. When any one of the bidirectional screws 421 rotates, it can drive the adjacent two clamping blocks to move towards or away from each other. Thus, the two bidirectional screws 421 and the clamping blocks in the two slide rails 420 drive the two pallets 430 to move synchronously towards or away from each other, so that the two pallets 430 can always support the annular workpiece when the annular workpiece deforms and increases in size after ring rolling. Moreover, by moving the positions of the two pallets 430 below the annular workpiece, one pallet 430 can synchronously drive the clamping mechanism 200 and the scraping mechanism 300 to move on the annular workpiece, so that the clamping mechanism 200, the scraping mechanism 300, and the supporting mechanism 400 are not likely to affect the ring rolling operation of the annular workpiece by the machine body 100.

[0044] Embodiment 2

[0045] Based on Embodiment 1, the cleaning effect on the annular workpiece is improved by setting up descaling nozzles 441.

[0046] As Figure 6-Figure 7 shown, in this embodiment, a plurality of embedding grooves are formed on the top surfaces of the two pallets 430. A knife plate 431 is slidably sleeved inside any one of the embedding grooves. A plurality of pressing springs 432 are fixedly connected between any one knife plate 431 and the bottom surface of the adjacent embedding groove. Two inclined U-shaped frames 440 are fixedly connected to the opposite sides of one pallet 430, and a plurality of descaling nozzles 441 are fixedly connected to one side of each of the two U-shaped frames 440.

[0047] During specific implementation, by connecting a plurality of descaling nozzles 441 to the air storage tank through pipelines, high-pressure gas can be ejected from the plurality of descaling nozzles 441 to clean the oxides on the surface of the annular workpiece. Moreover, the annular workpiece is supported by the knife plates 431. When the annular workpiece is driven by the machine body 100 to rotate, the bottom surface of the annular workpiece can be scraped by the knife plates 431 to clean the oxides.
