Description

Technical Field

[0001] The utility model relates to the technical field of tubing coupling processing, in particular to a novel sandblasting device for tubing coupling processing. Background Technique

[0002] A sandblasting device is a device that uses the impact of a high-speed sand stream to clean and roughen the surface of a substrate. It uses compressed air as power to form a high-speed jet beam to spray the abrasive at high speed onto the surface of the workpiece to be processed, causing changes in the appearance or shape of the outer surface of the workpiece surface, improving the fatigue resistance of the workpiece, increasing the adhesion between the workpiece and the coating, and prolonging the durability of the coating film. The sandblasting device for tubing coupling processing uses a push plate to push the tubing coupling to the middle of multiple sandblasting nozzles for sandblasting. There are still some defects in the existing devices; for example;

[0003] For example, a sandblasting device for tubing coupling processing with the publication number CN212146007U. When in use, it includes a sandblasting box. A horizontal fixed pipe is fixed on the right side wall of the sandblasting box, and a telescopic cylinder is fixed on the left side wall of the sandblasting box. The end of the telescopic rod of the telescopic cylinder is fixed with a motor. An outer retaining disc is penetrated through the output shaft of the motor.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0025] Please refer to Figures 1-5 , the present invention provides a technical solution: a sandblasting device for processing a new type of tubing coupling, including a machine body 1. The surface of the machine body 1 is connected to a box door through a hinge shaft, and a handle is provided on the surface of the box door.

Moreover, the moving plate 6 is slidably connected to the fixed rod 5. The fixed rod 5 is fixedly connected to the inside of the machine body 1, and the sand storage box 7 is slidably connected to the inside of the machine body 1. Moreover, an air extractor 9 is provided above the machine body 1, and the air extractor 9 is connected to the sand storage box 7. A feed pipe is connected above the sand storage box 7, and the feed pipe is slidably connected to the machine body 1. Moreover, a plug is provided inside the upper part of the feed pipe, and a spray head 10 is connected below the sand storage box 7;

[0026] When in use, after opening the box door above the surface of the machine body 1, the coupling of the tubing is sleeved on the sleeve 21 inside the machine body 1. Since the sleeve 21 is provided with layers, couplings of different sizes can be sleeved on the sleeve 21. At this time, the box door is closed. Then, the plug in the feed pipe above the machine body 1 is opened to add the sand for sandblasting into the sand storage box 7 inside the machine body 1. Then, the upper plug is closed. During use, the sand in the sand storage box 7 is sprayed onto the surface of the coupling through the spray head 10 for processing. At the same time, during the sandblasting process, the air extractor 9 can be used to draw external air into the sand storage box 7 to make the internal pressure higher, so that the sandblasting pressure is higher. At the same time, during use, the push rod 2 can be started to drive the slider 3 to slide inside the machine body 1, so that the slider 3 drives the moving plate 6 to move through the connecting rod 4. After the moving plate 6 slides on the fixed rod 5, the inside of the front sand storage box 7 moves, so that the height of the spray head 10 below is adjusted, so that the distance between the spray head 10 and the coupling is adjusted to adjust the sandblasting effect;

[0027] The inside of the body 1 is fixedly connected to the first motor 12, and the front end of the first motor 12 is fixedly connected to the adjusting rod 13. The adjusting rod 13 is hinged to the support rod 14, the front end of the support rod 14 is hinged to the moving block 15, and the front end of the moving block 15 is connected to the moving rod 16. The moving rod 16 is slidably connected to the inside of the body 1.

The inside of the fixed block 18 is fixedly connected to the second motor 19. The front end of the second motor 19 is connected to the sleeve 21. A scraper 20 is connected below the fixed block 18. A filter screen 11 is arranged inside the body 1. The inside of the body 1 is fixedly connected to the second spring 24, and the front end of the second spring 24 is fixedly connected to the top plate 8. The front end of the top plate 8 contacts the fixing plate 22. Through holes 23 are arranged on the surface of the fixing plate 22, and the through holes 23 are arranged in an array inside the fixing plate 22. One end of the fixing plate 22 is snap-fitted to the inside of the body 1;

[0028] Meanwhile, during use, the first motor 12 can be started to drive the adjustment of the adjusting rod 13. At the same time, the adjusting rod 13 drives the adjustment of the support rod 14, so that the support rod 14 drives the moving block 15 in front to move, so that the moving block 15 drives the moving rod 16 in front to move, so that the moving rod 16 moves the fixed block 18 in front. At the same time, the first spring 17 contracts, so that the fixed block 18 drives the sleeve 21 in front and the upper collar to adjust the position, which is convenient for sandblasting different positions of the collar. Meanwhile, during use, the second motor 19 can be started to drive the rotation of the sleeve 21, so that the upper collar rotates, which can better sandblast different positions of the collar. The used sand generated during the sandblasting process enters the lower part through the through holes 23 inside the fixing plate 22. At the same time, when the fixed block 18 moves, the scraper 20 below the fixed block 18 can scrape the excess sand on the surface of the fixing plate 22 into the through holes 23 and then filter it through the filter screen 11 below. The filter screen 11 can filter out the fine impurities generated during the sandblasting process through the filter screen 11, and the sand remains above the filter screen 11. When the use is over, after opening the box door below the body 1, the fixing plate 22 can be pushed to the left, so that the fixing plate 22 drives the top plate 8 to move, so that the second spring 24 behind the top plate 8 contracts. At this time, the fixing plate 22 is removed and replaced. At this time, the sand remaining above the filter screen 11 can be recycled and used again.

[0029] Working principle: When using the sandblasting device for processing new oil pipe couplings, after opening the box door above the surface of the machine body 1 during use, the coupling of the oil pipe is sleeved on the sleeve 21 inside the machine body 1. Since the sleeve 21 is provided with layers, couplings of different sizes can be sleeved on the sleeve 21. At this time, the box door is closed. Then, the plug in the feed pipe above the machine body 1 is opened to add the sand for sandblasting into the sand storage box 7 inside the machine body 1. Then, the upper plug is closed. During use, the sand in the sand storage box 7 is sprayed onto the surface of the coupling through the nozzle 10 for processing. At the same time, during the sandblasting process, the external air can be pumped into the sand storage box 7 by the air extractor 9 to increase the internal pressure, so that the sandblasting pressure is higher. At the same time, during use, the push rod 2 can be started to drive the slider 3 to slide inside the machine body 1, so that the slider 3 drives the moving plate 6 to move through the connecting rod 4. After the moving plate 6 slides on the fixed rod 5, the sand storage box 7 inside moves forward, so that the height of the nozzle 10 below is adjusted, and the distance between the nozzle 10 and the coupling is adjusted to adjust the sandblasting effect. At the same time, during use, the first motor 12 can be started to drive the adjusting rod 13 to adjust. At the same time, the adjusting rod 13 drives the support rod 14 to adjust, so that the support rod 14 drives the moving block 15 in front to move, so that the moving block 15 drives the moving rod 16 in front to move, so that the moving rod 16 moves the fixed block 18 in front. At the same time, the first spring 17 contracts, so that the fixed block 18 drives the sleeve 21 in front and the coupling above to adjust the position, which is convenient for sandblasting different positions of the coupling. At the same time, during use, the second motor 19 can be started to drive the sleeve 21 to rotate, so that the coupling above rotates, which can better sandblast different positions of the coupling. The used sand generated during the sandblasting process enters the lower part through the through hole 23 inside the fixed plate 22. At the same time, when the fixed block 18 moves, the scraper 20 below the fixed block 18 can scrape the excess sand on the surface of the fixed plate 22 into the through hole 23 and then filter it through the filter screen 11 below. The filter screen 11 can filter out the fine impurities generated during the sandblasting process through the filter screen 11, and the sand remains above the filter screen 11. When the use is over, the box door below the machine body 1 can be opened, and the fixed plate 22 is pushed to the left, so that the fixed plate 22 drives the top plate 8 to move, so that the second spring 24 behind the top plate 8 contracts. At this time, the fixed plate 22 is removed and replaced. At this time, the sand remaining above the filter screen 11 can be recycled and used again.
