Description

Technical Field

[0001] This invention relates to the technical field of hydrogen transport steel pipe processing, and in particular to a deburring device for the nozzle of hydrogen transport steel pipes. Background Technology

[0002] Deburring of steel pipes refers to a process in which burrs and residues are removed from the surface and interior of steel pipes by mechanical or chemical methods during the steel pipe processing. Burrs are excess metal shavings generated during the steel pipe processing due to plastic deformation, which can affect the quality and performance of the steel pipe and may even lead to safety hazards. Deburring equipment is required when deburring the pipe ends of steel pipes.

[0003] Existing deburring equipment includes a grinding device, support column, connecting frame, movable block, movable rod, side plate, return spring, and threaded rod. After the turntable rotates, it drives the threaded rod to rotate. The threaded rod moves up and down with the help of the threaded groove, thereby adjusting the position of the grinding disc. This ensures that one side of the grinding disc is in tight contact with the inner wall, outer side, and outer surface of one end of the steel pipe, thus achieving the deburring effect at the cut of the steel pipe. The adjustment is convenient and quick, adaptable to different steel pipe sizes and specifications, and improves the processing quality.

[0004] However, during the deburring process of steel pipe ends, debris and dust are generated. Some of the debris and dust will enter the inside of the steel pipe, requiring the inner wall of the steel pipe to be cleaned after deburring, which increases the workload. In addition, the dust adhering to the inner wall of the steel pipe will also make the cleaning work more difficult and the operation more troublesome. Summary of the Invention

Simultaneously, the shielding structure is inserted into the inner wall of the steel pipe. The rotating strip and shielding cloth on the shielding structure effectively shield the generated debris and dust during deburring. After deburring, when the shielding structure is removed, the rotating strip and shielding cloth directly remove some debris and dust from the steel pipe, improving the quality of the deburring process. Furthermore, the first adjusting structure allows the rotating strip to rotate according to the inner diameter of the steel pipe, adapting to different inner diameters and offering greater flexibility. The deburring block and deburring rod in the deburring structure simultaneously deburr the end face and its inner and outer edges, resulting in a more thorough deburring of the pipe opening.

[0018] 2. This invention, by incorporating a clamping structure and a shielding structure, allows the moving structure to automatically clamp and fix the steel pipe in the placement seat while driving the deburring structure to move for deburring. This prevents the steel pipe from moving during the deburring process. Simultaneously, the moving structure also pushes the shielding structure to move, shielding the debris generated during deburring, improving the quality of the working environment. Furthermore, the shielded debris falls into the collection box for convenient centralized processing.

[0019] 3. The present invention has an adjustment structure. After the steel pipe is placed on the placement seat, the steel pipe can be adjusted to the middle position on the placement seat through the adjustment structure. When the two sets of deburring structures move towards the middle at the same time, the two sets of deburring structures can be smoothly moved to the opening of the steel pipe for deburring processing.

[0030] The following is in conjunction with the appendix Figures 1-9 The present invention will be described in further detail below.

[0031] This invention discloses a deburring device for the nozzle of a hydrogen transport steel pipe.

[0032] A deburring device for hydrogen transport steel pipe nozzles includes a processing table 1 and a placement seat 2. The placement seat 2 is installed in the middle of the processing table 1. A feeding groove 3 is provided on both the left and right sides of the placement seat 2 on the processing table 1. A clamping structure is provided inside the placement seat 2. An adjustment structure is provided in the middle of the upper part of the processing table 1. A moving structure is provided on both sides of the upper part of the processing table 1. A collection frame 47 is provided below the processing table 1. The collection frame 47 is detachably installed on the processing table 1 by means of an installation strip 48.

[0033] The movable structure is provided on the left and right sides of the processing table 1 with four sets of protrusions 4. A crossbar 5 is connected between two protrusions 4 in each set. A movable plate 6 is movably mounted on each of the two crossbars 5. A push plate 8 is connected to the lower part of the side of the movable plate 6 away from the cylinder 7. A cylinder 7 is installed in the middle of the left and right sides of the processing table 1. One end of the output shaft of the cylinder 7 is connected to the movable plate 6. A through rod 9 is fixedly passed through the upper part of the movable plate 6 near both ends. A transverse groove 34 is provided on the processing table 1 for the through rod 9 to pass through. A first motor 10 is installed on the upper part of the side of the movable plate 6 near the cylinder 7. A fixed frame 11 is installed on the end of the output shaft of the first motor 10 that passes through the movable plate 6. A fixed cylinder 12 is fixedly connected to the middle of the side of the fixed frame 11 away from the movable plate 6. A shielding structure is provided at one end of the fixed cylinder 12. A shielding structure is provided on the left and right sides of the processing table 1.

[0034] The shielding structure includes multiple flip bars 15 located at one end of the fixed cylinder 12 away from the fixed frame 11. The multiple flip bars 15 are distributed at equal angles around one end of the fixed cylinder 12. A first adjustment structure is provided inside the fixed cylinder 12. A shielding cloth 16 is connected between each two adjacent flip bars 15. The shielding cloth 16 and the flip bars 15 are umbrella-shaped as a whole. A deburring structure is provided on the fixed frame 11.

[0035] The first adjustment structure includes a movable bar 19 that moves through the fixed frame 11. The end face of the movable bar 19 is square-shaped. A driving rod 17 is connected to one end of the movable bar 19 that is inserted into the fixed cylinder 12. A threaded rod 20 is inserted into a threaded groove on the other end face of the movable bar 19. One end of the threaded rod 20 is rotatably connected to the inner wall of the fixed frame 11. A turntable 21 is fixedly sleeved on the threaded rod 20 near the cylinder 7. An opening 13 is opened at one end of the fixed cylinder 12 corresponding to the position of each rotating bar 15. A fixed shaft is rotatably connected between the inner walls on both sides of each opening 13. One end of each rotating bar 15 is fixedly sleeved on the corresponding fixed shaft. A first gear 14 is fixedly sleeved in the middle of the fixed shaft. The side of the driving rod 17 corresponds to each first gear 14. Each position is equipped with a drive bar 18, which has teeth that mesh with the first gear 14. During deburring, the cylinder 7 is activated to move the moving plate 6 closer to the opening of the steel pipe, causing the flipping bar 15 and the shielding cloth 16 to be inserted into the steel pipe as a whole, and causing the deburring block 25 to be attached to the opening of the steel pipe. At this time, the turntable 21 rotates the threaded rod 20, and the moving bar 19 moves on the fixed frame 11, pulling the drive rod 17 to move inside the fixed cylinder 12. Through the drive bar 18 on the drive rod 17 and the first gear 14, the flipping bar 15 and the shielding cloth 16 are flipped as a whole, so that the flipping bar 15 and the shielding cloth 16 can shield the debris generated during the deburring process, reducing the problem of debris and dust entering the inside of the steel pipe and causing it to be difficult to clean.

[0036] See Figure 1 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The deburring structure includes a second motor 32 installed on the inner wall of the fixed frame 11 near the moving strip 19. A third gear 33 is sleeved on one end of the output shaft of the second motor 32, which passes through the fixed frame 11. A rotating sleeve 22 is rotatably mounted on the middle of the side of the fixed frame 11 away from the first motor 10. The rotating sleeve 22 is movably sleeved on the fixed cylinder 12. A second gear 23 is fixedly sleeved on the rotating sleeve 22, and the second gear 23 meshes with the third gear 33. The rotating sleeve 22 is connected to... Two L-shaped strips 24 are connected and distributed on the radial side of the rotating sleeve 22. A deburring block 25 is installed on the end of each L-shaped strip 24 away from the rotating sleeve 22. A first groove 26 is opened in the middle of the upper and lower sides of the deburring block 25. An adjusting strip 27 is movably inserted into each first groove 26. The adjusting strip 27 is set on the L-shaped strip 24 through a second adjusting structure. A deburring rod 28 is installed at one end of the adjusting strip 27. The deburring rod 28 is truncated cone-shaped.

[0037] The second adjustment structure includes a fixing rod 31 that passes through the L-shaped strip 24 near one end of the deburring block 25. The adjustment strip 27 has a through hole for the fixing rod 31 to pass through. A bidirectional screw 29 rotates through the L-shaped strip 24. A rotating block 30 is installed on both ends of the bidirectional screw 29. The other end of the adjustment strip 27 has a threaded groove for the bidirectional screw 29 to pass through. Depending on the thickness of the steel pipe, the bidirectional screw 29 can be rotated using the rotating block 30. The two deburring rods 28 move in opposite directions on the rotating bidirectional screw 29, so that the two deburring rods 28 fit against the inner and outer edges of the steel pipe opening. Thus, when the first motor 10 is started to drive the L-shaped strip 24 to rotate, the end face and inner and outer edges of the steel pipe opening can be deburred simultaneously through the deburring block 25 and the deburring rods 28, improving the processing quality.

[0038] See Figures 1-5 The clamping structure includes a second groove 35 located in the middle of the front and rear sides of the placement seat 2. Each of the two second grooves 35 is provided with a clamping plate 36. The side of the two clamping plates 36 that are close to each other is concave. A through groove 37 is provided in the middle of the lower groove wall of the second groove 35. A through plate 38 is connected to the middle of the lower part of the clamping plate 36. The bottom end of the through plate 38 extends out of the through groove 37. A cylindrical rod 39 is fixedly passed through the through plate 38 near the bottom end along the length of the processing table 1. A driving plate 40 is connected to both ends of each cylindrical rod 39. Each driving plate 40 is provided with a driving groove 41 for the bottom end of the corresponding through rod 9 to pass through. The driving groove 41 is "Z" shaped. During the movement of the moving plate 6, the through rod 9 slides in the driving groove 41 of the driving plate 40, thereby automatically driving the two clamping plates 36 to move closer to each other in the second groove 35, thereby clamping and fixing the steel pipe in the placement seat 2.

[0039] The adjustment structure includes a U-shaped frame 42 fastened to the middle of the processing table 1 by bolts. A vertical rod is connected to the middle of the upper part of the U-shaped frame 42. A pressing tube 43 is movably sleeved on the vertical rod. An adjustment plate 45 is installed on the top of the pressing tube 43. The adjustment plate 45 is in the shape of an inverted "U". An adjustment part 46 with an inclined surface is provided on both bottom ends of the adjustment plate 45. A first spring 44 is sleeved on the vertical rod. The two ends of the first spring 44 are respectively connected to the pressing tube 43 and the U-shaped frame 42. After the steel pipe is placed on the placement seat 2, the adjustment plate can be pressed down directly. The steel pipe opening is squeezed by the adjustment part 46, thereby pushing the steel pipe to the middle position on the placement seat 2, so that the two sets of deburring blocks 25 can be smoothly moved to the steel pipe opening for deburring work.

[0040] The shielding structure includes shielding covers 49 located on the left and right sides of the processing table 1. Movable blocks 50 are installed on the front and rear edges of the shielding covers 49. A guide groove 51 is provided on the processing table 1 for the movable blocks 50 to slide. A horizontal shaft 52 is connected between the two ends of the guide groove 51. A through hole is provided on the movable block 50 for the horizontal shaft 52 to pass through. A second spring 53 is sleeved on the horizontal shaft 52. The two ends of the second spring 53 are respectively connected to the movable block 50 and one end of the guide groove 51. A circular groove 54 is provided in the middle of the left and right sides of the shielding cover 49. A shielding bucket 55 is installed in the middle of the side of the shielding cover 49 near the cylinder 7. When the movable plate 6 moves, it drives the push plate 8 to move. The push plate 8 pushes the shielding cover 49 to the top of the feeding trough 3. In this way, the debris generated during the deburring process can be shielded, improving the quality of the working environment. The debris under the shielding falls into the collection frame 47 for collection and centralized processing.

[0041] The implementation principle of a deburring device for hydrogen transport steel pipe nozzles according to an embodiment of the present invention is as follows: First, the steel pipe to be deburred is placed in the placement seat 2. The operator directly presses the adjusting plate 45, which drives the pressing pipe 43 to move up and down on the vertical rod, compressing the first spring 44. Through the pressing of the adjusting parts 46 at both ends of the adjusting plate 45 on the nozzles of the steel pipe, the steel pipe is pushed to the middle position on the placement seat 2. Then, the adjusting plate 45 is released, and under the elastic force of the first spring 44, the adjusting plate 45 is pushed upward to reset. Then, the cylinder 7 is started. The moving plate 6 moves along the crossbar 5 towards one side of the steel pipe. The moving plate 6 drives the through rod 9 to slide in the driving groove 41 of the driving plate 40, pushing the two clamping plates 36 in the second groove 35 to move closer to each other, thereby clamping and fixing the steel pipe in the placement seat 2. The push plate 8 on the moving plate 6 pushes the shield 49 to the position above the discharge chute 3. When the moving plate 6 drives the flipping bar 15 to insert into the steel pipe and the deburring block 25 is pressed against the end face of the steel pipe opening, the turntable 21 rotates the threaded rod 20, and the moving bar 19 moves along the crossbar 5 to the side of the steel pipe. The rotating threaded rod 20 moves, pulling the driving rod 17 to move inside the fixed cylinder 12. Through the driving bar 18 on the driving rod 17 and the first gear 14, the flipping bar 15 and the shielding cloth 16 are flipped as a whole, so that the flipping bar 15 and the shielding cloth 16 can shield the debris generated during the deburring process. The rotating block 30 rotates the bidirectional screw 29, and the two deburring rods 28 move in opposite directions on the rotating bidirectional screw 29 at the same time, so that the two deburring rods 28 are in contact with the inner and outer edges of the steel pipe opening. Finally, the process can be started. The first motor 10 drives the deburring block 25 and the deburring rod 28 to rotate as a whole, performing deburring work on the end face and inner and outer edges of the steel pipe. The umbrella-shaped flipping strip 15 and the shielding cloth 16 are used to shield the debris and dust generated during the deburring process, reducing the debris and dust from entering the steel pipe and causing difficulties in cleaning. At the same time, the shielding cover 49 shields the debris generated during the deburring process, improving the quality of the working environment. The debris under the shielding falls into the collection frame 47 for convenient centralized treatment. In this way, the deburring work on the end face of the steel pipe can be achieved.

[0042] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
