Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. Example 1

[0021] like Figure 1 and 2 As shown, a steel pipe shaping and docking device includes a positioning device 5 comprising a fixing ring 51 and an adjusting ring 52. An adjusting device 6 is provided between the fixing ring 51 and the adjusting ring 52 to change the distance between them. One end of the steel pipe 10 extends between the fixing ring 51 and the adjusting ring 52. Since most steel pipes 10 have a coating on their surface, the coating at the docking ends needs to be removed before docking. Then, the two steel pipes 10 are docked by welding or other methods. When removing the coating at the ends of the steel pipes 10 and completing the docking, the steel pipes 10 need to be firmly fixed to improve the accuracy of the operation. This prevents the steel pipes 10 from shaking, swinging, or moving during coating removal or docking, which could lead to inaccurate coating removal depth and damage to the steel pipes 10. It also prevents the axes of the steel pipes 10 from not aligning during docking, resulting in gaps or thin joints at the docking position. Therefore, the positioning device 5 is used to fix the steel pipes 10 to be docked to improve the accuracy of coating removal and docking.

[0022] The fixed ring 51 has adjustment grooves 511 at both ends, and one end of the adjustment ring 52 is disposed in the adjustment groove 511. Guide grooves 512 are provided on both sides of the adjustment groove 511, and the adjustment device 6 moves up and down along the guide grooves 512. The adjustment grooves 511 facilitate the adjustment of the adjustment ring 52 by the adjustment device. By changing the relative position between the fixed ring 51 and the adjustment ring 52, the steel pipe 10 can be clamped. This structure can also be used to clamp steel pipes 10 of different diameters.

[0023] Since the steel pipe 10 is cylindrical, the positioning device 5 needs to position the steel pipe 10 around its circumference. Therefore, each positioning device 5 includes two fixing rings 51 and two adjusting rings 52. One end of each fixing ring 51 engages with one adjusting ring 52. The adjusting ring 52 includes a first connecting ring 523 and a second connecting ring 522. One end of the first connecting ring 523 is fixedly connected to the second connecting ring 522. The end of the first connecting ring 523 away from the second connecting ring 522 is engaged with one of the fixing rings 51. The end of the second connecting ring 522 away from the first connecting ring 523 is engaged with the other fixing ring 51. The positioning device 5 comprises a first positioning ring 51, a first adjusting ring 52, a second positioning ring 51, and a second adjusting ring 52 connected in sequence. The first positioning ring 51, the first adjusting ring 52, the second positioning ring 51, and the second adjusting ring 52 form a closed ring. The steel pipe 10 is located in the middle of this ring. Each adjusting ring 52 includes a first connecting ring 523 and a second connecting ring 522.

[0024] To adjust the fixed ring 51 and the adjusting ring 52, changing the diameter formed between them to clamp the steel pipe 10, an adjusting device 6 is used. The adjusting device 6 includes an adjusting bracket 61, a first motor 62, an adjusting screw 63, adjusting blocks 64, a first bevel gear 65, and a second bevel gear 66. The adjusting screw 63 has reverse threads at both ends, and each end of the adjusting screw 63 is threaded with an adjusting block 64. The first motor 62 drives the adjusting screw to rotate, causing the adjusting blocks 64 to move closer or further apart. The adjusting bracket 61 is fixedly mounted on the fixed ring 51, and the first motor 62 is fixedly mounted on the adjusting bracket 61. The output end of the first motor 62 is connected to the first bevel gear 65. The second bevel gear 66 is coaxially fixed with the adjusting screw 63, and the first bevel gear 65 meshes with the second bevel gear 66. Guide blocks 641 are provided on both sides of the adjusting block 64, and each guide block 641 is slidably disposed in each guide groove 512; the adjusting block 64 is provided with a through groove 642, and a connecting rod 643 is provided in the through groove 642. One end of the connecting rod 643 is connected to one end of the adjusting ring 52, and the other end of the connecting rod 643 is provided with a limit block 644. The width of the limit block 644 is greater than the width of the through groove 642.

[0025] Guide blocks 641 are provided on both sides of the adjusting block 64. One end of each guide block 641 slides along the length of the adjusting block 64, and the other end of each guide block 641 slides within each guide groove 512. The adjusting block 64 is provided with a through groove 642, and a connecting rod 643 is provided within the through groove 642. One end of the connecting rod 643 is connected to one end of the adjusting ring 52, and the other end of the connecting rod 643 is provided with a limit block 644. The width of the limit block 644 is greater than the width of the through groove 642. A sliding limit groove 645 is provided on the adjusting block 64, which is provided along the length of the adjusting block 64. One end of each guide block 641 is located within the sliding limit groove 645 and slides along the length of the sliding limit groove 645. When the adjusting block 64 rotates with the adjusting screw 63, the guide block 64 moves, thus fixing the adjusting block 64 and preventing it from being damaged by excessive force from the adjusting screw 63.

[0026] The first motor 62 drives the adjusting screw 63 to rotate. The threads at both ends of the adjusting screw 63 are reversed. Because the two adjusting blocks 64 are set in the adjusting groove 511, when the adjusting screw 63 rotates in the forward or reverse direction, the adjusting blocks 64 that are threaded with the adjusting screw 63 will not rotate with the adjusting screw 63, but will move linearly along the adjusting screw 63 under the action of the adjusting groove 511. The two adjusting blocks 64 will move away from or towards each other. Each adjusting block 64 is provided with a guide block 641 on both sides, and each guide block 641 is slidably set in each guide groove 512. When the adjusting screw 63 drives the adjusting block 64 to move along the adjusting screw 63, the adjusting blocks 64 will move linearly along the adjusting screw 63. When the length of the 3 moves, the adjusting block 64 can move smoothly between the adjusting grooves 511. Since the adjusting block 64 is provided with a through groove 642, and a connecting rod 643 is provided in the through groove 642, one end of the connecting rod 643 is connected to one end of the adjusting ring 52, and the other end of the connecting rod 643 is provided with a limit block 644, when the adjusting block 64 moves, it drives the two adjusting rings 52 to move, changing the distance between the two adjusting rings 52. The change in the distance between the two adjusting rings 52 clamps or loosens the steel pipe 10. By adjusting the distance between the two adjusting rings 52 as needed, steel pipes 10 of different diameters can be clamped. Example 2

[0027] like Figure 1-4As shown, a steel pipe shaping and docking device includes several adjustable drive components 521 arranged on the inner ring of the adjusting ring 52. Each adjustable drive component 521 includes a fixed tube 5211, a movable shaft 5212, a roller 5213, a drive motor 5214, a first gear 5215, a second gear 5216, a second rotating shaft 5217, a second motor 5218, and a side plate 5219. One end of the fixed tube 5211 is fixedly disposed on the inner ring of the adjusting ring 52, and the other end of the fixed tube 5211 is sleeved on one end of the movable shaft 5212. The other end of the movable shaft 5212 is connected to the roller 5213. The drive motor 5214 drives the roller 5213 to rotate. To remove the coating from the docking ends of the steel pipe 10, to clamp the steel pipe 10 during docking, and to avoid damaging the coating on the surface of the steel pipe 10 that does not need to be removed, several adjustable drive components 521 are arranged on the inner ring of the adjusting ring 52. The adjustable drive assembly 521 uses a drive motor 5214 to drive the movable shaft 5212 to rotate. A roller 5213 located at one end of the movable shaft 5212 changes direction with the second motor 5218. When the roller 5213 is parallel to the axis of the steel pipe 10, the roller 5213 and the steel pipe 10 can rotate simultaneously, facilitating the removal of the coating from the mating end of the steel pipe 10. When the diameter of the steel pipe 10 is large, the drive motor 5214 can be activated to save effort, at which point the roller 5213 drives the steel pipe 10 to rotate. When mating is required, if the roller 5213 is not parallel to the axis of the steel pipe 10, the steel pipe 10 is essentially locked and cannot move, resulting in higher mating precision.

[0028] The second motor 5218 drives the movable shaft 5212 to rotate in the following manner: the side plate 5219 is fixedly mounted on the fixed tube 5211, the second motor 5218 is fixedly mounted on the side plate 5219, the second gear 5216 is mounted on one end of the second rotating shaft 5217, the other end of the second rotating shaft 5217 is connected to the second motor 5218 for transmission, the first gear 5215 is coaxially fixed with the movable shaft 5212, and the first gear 5215 meshes with the second gear 5216.

[0029] To lock the angle of the roller 5213, a through hole 52111 is provided inside the fixed tube 5211. One end of the movable shaft 5212 is located inside the through hole 52111. Two positioning rods 52121 are symmetrically arranged inside the movable shaft 5212, and a first spring 52122 is provided between the two positioning rods 52121. Four positioning grooves 52123 are formed on the inner wall of the fixed tube 5211, and the four positioning grooves 52123 are arranged in a ring array. The positioning rods 52121 are respectively inserted into the positioning grooves 52123. The four positioning grooves 52123 are used to hold the positioning rods 52121, thereby locking the movable shaft 5212, further locking the angle of the roller 5213, and preventing the movable shaft 5212 from detaching from the fixed tube 5211.

[0030] The positioning device 5 includes a fixed ring 51 and an adjusting ring 52. An adjusting device 6 is provided between the fixed ring 51 and the adjusting ring 52. The adjusting device changes the distance between the fixed ring 51 and the adjusting ring 52. One end of the steel pipe 10 extends between the fixed ring 51 and the adjusting ring 52. Since most steel pipes 10 have a coating on their surface, the coating at the joint ends needs to be removed before the two steel pipes 10 are joined by welding or other methods. When removing the coating at the ends of the steel pipes 10 and completing the joint, the steel pipes 10 need to be firmly fixed to improve the accuracy of the operation. This is to prevent the steel pipes 10 from shaking, swinging, or moving during the coating removal or jointing process, which could lead to inaccurate coating removal depth and damage to the steel pipes 10, or misalignment of the axes of the steel pipes 10 during the jointing process, resulting in gaps or thin joints at the joint. Therefore, the positioning device 5 is used to fix the steel pipes 10 to be joined to improve the accuracy of coating removal and jointing.

[0031] The fixed ring 51 has adjustment grooves 511 at both ends, and one end of the adjustment ring 52 is disposed in the adjustment groove 511. Guide grooves 512 are provided on both sides of the adjustment groove 511, and the adjustment device 6 moves up and down along the guide grooves 512. The adjustment grooves 511 facilitate the adjustment of the adjustment ring 52 by the adjustment device. By changing the relative position between the fixed ring 51 and the adjustment ring 52, the steel pipe 10 can be clamped. This structure can also be used to clamp steel pipes 10 of different diameters.

[0032] Since the steel pipe 10 is cylindrical, the positioning device 5 needs to position the steel pipe 10 around its circumference. Therefore, each positioning device 5 includes two fixing rings 51 and two adjusting rings 52. One end of each fixing ring 51 engages with one adjusting ring 52. The adjusting ring 52 includes a first connecting ring 523 and a second connecting ring 522. One end of the first connecting ring 523 is fixedly connected to the second connecting ring 522. The end of the first connecting ring 523 away from the second connecting ring 522 is engaged with one of the fixing rings 51. The end of the second connecting ring 522 away from the first connecting ring 523 is engaged with the other fixing ring 51. The positioning device 5 comprises a first positioning ring 51, a first adjusting ring 52, a second positioning ring 51, and a second adjusting ring 52 connected in sequence. The first positioning ring 51, the first adjusting ring 52, the second positioning ring 51, and the second adjusting ring 52 form a closed ring. The steel pipe 10 is located in the middle of this ring. Each adjusting ring 52 includes a first connecting ring 523 and a second connecting ring 522.

[0033] To adjust the fixed ring 51 and the adjusting ring 52, changing the diameter formed between them to clamp the steel pipe 10, an adjusting device 6 is used. The adjusting device 6 includes an adjusting bracket 61, a first motor 62, an adjusting screw 63, adjusting blocks 64, a first bevel gear 65, and a second bevel gear 66. The adjusting screw 63 has reverse threads at both ends, and each end of the adjusting screw 63 is threaded with an adjusting block 64. The first motor 62 drives the adjusting screw to rotate, causing the adjusting blocks 64 to move closer or further apart. The adjusting bracket 61 is fixedly mounted on the fixed ring 51, and the first motor 62 is fixedly mounted on the adjusting bracket 61. The output end of the first motor 62 is connected to the first bevel gear 65. The second bevel gear 66 is coaxially fixed with the adjusting screw 63, and the first bevel gear 65 meshes with the second bevel gear 66. Guide blocks 641 are provided on both sides of the adjusting block 64, and each guide block 641 is slidably disposed in each guide groove 512; the adjusting block 64 is provided with a through groove 642, and a connecting rod 643 is provided in the through groove 642. One end of the connecting rod 643 is connected to one end of the adjusting ring 52, and the other end of the connecting rod 643 is provided with a limit block 644. The width of the limit block 644 is greater than the width of the through groove 642.

[0034] Guide blocks 641 are provided on both sides of the adjusting block 64. One end of each guide block 641 slides along the length of the adjusting block 64, and the other end of each guide block 641 slides within each guide groove 512. The adjusting block 64 is provided with a through groove 642, and a connecting rod 643 is provided within the through groove 642. One end of the connecting rod 643 is connected to one end of the adjusting ring 52, and the other end of the connecting rod 643 is provided with a limit block 644. The width of the limit block 644 is greater than the width of the through groove 642. A sliding limit groove 645 is provided on the adjusting block 64, which is provided along the length of the adjusting block 64. One end of each guide block 641 is located within the sliding limit groove 645 and slides along the length of the sliding limit groove 645. When the adjusting block 64 rotates with the adjusting screw 63, the guide block 64 moves, thus fixing the adjusting block 64 and preventing it from being damaged by excessive force from the adjusting screw 63.

[0035] The first motor 62 drives the adjusting screw 63 to rotate. The threads at both ends of the adjusting screw 63 are reversed. Because the two adjusting blocks 64 are set in the adjusting groove 511, when the adjusting screw 63 rotates in the forward or reverse direction, the adjusting blocks 64 that are threaded with the adjusting screw 63 will not rotate with the adjusting screw 63, but will move linearly along the adjusting screw 63 under the action of the adjusting groove 511. The two adjusting blocks 64 will move away from or towards each other. Each adjusting block 64 is provided with a guide block 641 on both sides, and each guide block 641 is slidably set in each guide groove 512. When the adjusting screw 63 drives the adjusting block 64 to move along the adjusting screw 63, the adjusting blocks 64 will move linearly along the adjusting screw 63. When the length of the 3 moves, the adjusting block 64 can move smoothly between the adjusting grooves 511. Since the adjusting block 64 is provided with a through groove 642, and a connecting rod 643 is provided in the through groove 642, one end of the connecting rod 643 is connected to one end of the adjusting ring 52, and the other end of the connecting rod 643 is provided with a limit block 644, when the adjusting block 64 moves, it drives the two adjusting rings 52 to move, changing the distance between the two adjusting rings 52. The change in the distance between the two adjusting rings 52 clamps or loosens the steel pipe 10. By adjusting the distance between the two adjusting rings 52 as needed, steel pipes 10 of different diameters can be clamped. Example 3

[0036] like Figure 1-6 As shown, a steel pipe shaping and docking device is disclosed. Each positioning device 5 comprises two units, with a fixing plate 1 positioned between the two positioning devices 5. The two positioning devices 5 are aligned in a straight line, and a steel pipe 10 is disposed within each positioning device 5. A mounting positioning assembly 11 is mounted on the fixing plate 1. The mounting positioning assembly 11 includes a clamping plate 111, a clamping bolt 112, and a clamping adjusting spring 113. The clamping plate 111 is disposed on one side of the fixing plate 1, and the clamping adjusting spring 113 is disposed on the other side of the fixing plate 1. The clamping bolt 112 passes through the fixing plate 1 and is threadedly engaged with the clamping plate 111. The clamping bolt 112 also passes through the clamping adjusting spring 113. The mounting positioning assembly 11 can fix the positioning devices 5, as well as the docking device or coating removal device, improving the accuracy of coating removal and docking. In this embodiment, welding is used as an example of docking. Steel pipe welding is existing technology; therefore, this patent does not provide a detailed description of the structure of the welding device.

[0037] The positioning device 5 includes a fixed ring 51 and an adjusting ring 52. An adjusting device 6 is provided between the fixed ring 51 and the adjusting ring 52. The adjusting device changes the distance between the fixed ring 51 and the adjusting ring 52. One end of the steel pipe 10 extends between the fixed ring 51 and the adjusting ring 52. Since most steel pipes 10 have a coating on their surface, the coating at the joint ends needs to be removed before the two steel pipes 10 are joined by welding or other methods. When removing the coating at the ends of the steel pipes 10 and completing the joint, the steel pipes 10 need to be firmly fixed to improve the accuracy of the operation. This is to prevent the steel pipes 10 from shaking, swinging, or moving during the coating removal or jointing process, which could lead to inaccurate coating removal depth and damage to the steel pipes 10, or misalignment of the axes of the steel pipes 10 during the jointing process, resulting in gaps or thin joints at the joint. Therefore, the positioning device 5 is used to fix the steel pipes 10 to be joined to improve the accuracy of coating removal and jointing.

[0038] The fixed ring 51 has adjustment grooves 511 at both ends, and one end of the adjustment ring 52 is disposed in the adjustment groove 511. Guide grooves 512 are provided on both sides of the adjustment groove 511, and the adjustment device 6 moves up and down along the guide grooves 512. The adjustment grooves 511 facilitate the adjustment of the adjustment ring 52 by the adjustment device. By changing the relative position between the fixed ring 51 and the adjustment ring 52, the steel pipe 10 can be clamped. This structure can also be used to clamp steel pipes 10 of different diameters.

[0039] Since the steel pipe 10 is cylindrical, the positioning device 5 needs to position the steel pipe 10 around its circumference. Therefore, each positioning device 5 includes two fixing rings 51 and two adjusting rings 52. One end of each fixing ring 51 engages with one adjusting ring 52. The adjusting ring 52 includes a first connecting ring 523 and a second connecting ring 522. One end of the first connecting ring 523 is fixedly connected to the second connecting ring 522. The end of the first connecting ring 523 away from the second connecting ring 522 is engaged with one of the fixing rings 51. The end of the second connecting ring 522 away from the first connecting ring 523 is engaged with the other fixing ring 51. The positioning device 5 comprises a first positioning ring 51, a first adjusting ring 52, a second positioning ring 51, and a second adjusting ring 52 connected in sequence. The first positioning ring 51, the first adjusting ring 52, the second positioning ring 51, and the second adjusting ring 52 form a closed ring. The steel pipe 10 is located in the middle of this ring. Each adjusting ring 52 includes a first connecting ring 523 and a second connecting ring 522.

[0040] To adjust the fixed ring 51 and the adjusting ring 52, changing the diameter formed between them to clamp the steel pipe 10, an adjusting device 6 is used. The adjusting device 6 includes an adjusting bracket 61, a first motor 62, an adjusting screw 63, adjusting blocks 64, a first bevel gear 65, and a second bevel gear 66. The adjusting screw 63 has reverse threads at both ends, and each end of the adjusting screw 63 is threaded with an adjusting block 64. The first motor 62 drives the adjusting screw to rotate, causing the adjusting blocks 64 to move closer or further apart. The adjusting bracket 61 is fixedly mounted on the fixed ring 51, and the first motor 62 is fixedly mounted on the adjusting bracket 61. The output end of the first motor 62 is connected to the first bevel gear 65. The second bevel gear 66 is coaxially fixed with the adjusting screw 63, and the first bevel gear 65 meshes with the second bevel gear 66. Guide blocks 641 are provided on both sides of the adjusting block 64, and each guide block 641 is slidably disposed in each guide groove 512; the adjusting block 64 is provided with a through groove 642, and a connecting rod 643 is provided in the through groove 642. One end of the connecting rod 643 is connected to one end of the adjusting ring 52, and the other end of the connecting rod 643 is provided with a limit block 644. The width of the limit block 644 is greater than the width of the through groove 642.

[0041] Guide blocks 641 are provided on both sides of the adjusting block 64. One end of each guide block 641 slides along the length of the adjusting block 64, and the other end of each guide block 641 slides within each guide groove 512. The adjusting block 64 is provided with a through groove 642, and a connecting rod 643 is provided within the through groove 642. One end of the connecting rod 643 is connected to one end of the adjusting ring 52, and the other end of the connecting rod 643 is provided with a limit block 644. The width of the limit block 644 is greater than the width of the through groove 642. A sliding limit groove 645 is provided on the adjusting block 64, which is provided along the length of the adjusting block 64. One end of each guide block 641 is located within the sliding limit groove 645 and slides along the length of the sliding limit groove 645. When the adjusting block 64 rotates with the adjusting screw 63, the guide block 64 moves, thus fixing the adjusting block 64 and preventing it from being damaged by excessive force from the adjusting screw 63.

[0042] The first motor 62 drives the adjusting screw 63 to rotate. The threads at both ends of the adjusting screw 63 are reversed. Because the two adjusting blocks 64 are set in the adjusting groove 511, when the adjusting screw 63 rotates in the forward or reverse direction, the adjusting blocks 64 that are threaded with the adjusting screw 63 will not rotate with the adjusting screw 63, but will move linearly along the adjusting screw 63 under the action of the adjusting groove 511. The two adjusting blocks 64 will move away from or towards each other. Each adjusting block 64 is provided with a guide block 641 on both sides, and each guide block 641 is slidably set in each guide groove 512. When the adjusting screw 63 drives the adjusting block 64 to move along the adjusting screw 63, the adjusting blocks 64 will move linearly along the adjusting screw 63. When the length of the 3 moves, the adjusting block 64 can move smoothly between the adjusting grooves 511. Since the adjusting block 64 is provided with a through groove 642, and a connecting rod 643 is provided in the through groove 642, one end of the connecting rod 643 is connected to one end of the adjusting ring 52, and the other end of the connecting rod 643 is provided with a limit block 644, when the adjusting block 64 moves, it drives the two adjusting rings 52 to move, changing the distance between the two adjusting rings 52. The change in the distance between the two adjusting rings 52 clamps or loosens the steel pipe 10. By adjusting the distance between the two adjusting rings 52 as needed, steel pipes 10 of different diameters can be clamped. Example 4

[0043] like Figure 1-9 As shown, a steel pipe shaping and docking device is disclosed. The shaping device 2 includes a shaping frame 21, a shaping motor 22, a shaping plate 23, a fixed transmission belt 24, and a moving conveyor belt 25. The shaping fixed roller 3 and the shaping adjusting roller 4 are both mounted on the shaping frame 21. The shaping motor 22 drives the shaping fixed roller 3 to rotate. The shaping plate 23 is fixedly mounted on the shaping frame 21, and the shaping fixed roller 3 is rotatably mounted on the shaping plate 23. The fixed transmission belt 24 is driven between the power output end of the shaping motor 22 and the shaping fixed roller 3.

[0044] Each positioning device 5 is paired with a shaping device 2, and the positioning device 5 is fixedly mounted on the connecting frame 211 between the shaping frames 21 of the two shaping devices 2.

[0045] The shaping fixed roller 3 is provided with a positioning groove 31, and the shaping adjusting roller 4 is provided with a shaping groove 44. Both the positioning groove 31 and the shaping groove 44 are configured to cooperate with the steel pipe 10. The output end of the shaping motor 22 is provided with a drive wheel 221. Both the shaping fixed roller 3 and the shaping adjusting roller 4 include two rollers. The shaping fixed roller 3 is coaxially fixed with a first fixed transmission wheel 32 and a second fixed transmission wheel 33. The fixed transmission belt 24 is disposed between the first fixed transmission wheel 32 and the drive wheel 221. The shaping adjusting roller 4 is coaxially fixed with a first shaping adjusting roller 41. The moving conveyor belt 25 is disposed between the second fixed transmission wheel 33 and the first shaping adjusting roller 41.

[0046] The shaping adjusting roller 4 is drivenly connected to the shaping shaft 42. The shaping plate 23 is provided with an arc-shaped adjusting groove 48. The shaping adjusting roller 4 is located on one side of the shaping plate 23, and the first shaping adjusting roller 41 is located on the other side of the shaping plate 23. The shaping shaft 42 is hinged to a connecting piece 43, and the other end of the connecting piece 43 is hinged to a connecting pin 44. An adjusting rod 45 is provided inside the connecting pin 44. One end of the adjusting rod 45 is fixedly mounted on the shaping frame 21. A swing adjusting block 46 is provided at the end of the adjusting rod 45 near the connecting pin 44. A swing nut 47 is provided with the adjusting rod 45.

[0047] It also includes a feeding guide roller 7, which is arranged on the same horizontal line as the shaping and adjusting roller 4. The feeding guide roller 7 is arranged on the shaping frame 21, and the shaping and adjusting plate 211 is arranged on the shaping frame 21. Adjusting bearings 71 are arranged at both ends of the feeding guide roller 7, and the adjusting bearings 71 are connected to the adjusting roller shaft 72. The adjusting roller shaft 72 is threadedly fitted with an upper radial nut 73 and a lower radial nut 74. The upper radial nut 73 is arranged above the shaping and adjusting plate 211, and the lower radial nut 74 is arranged below the shaping and adjusting plate 211. The height of the feed guide roller 7 can be adjusted by adjusting bearing 71, adjusting roller shaft 72, upper radial nut 73, and lower radial nut 74. When the steel pipe 10 has a large diameter and heavy weight, it is difficult to put the steel pipe 10 into the equipment. At this time, the height of the feed guide roller 7 can be lowered by adjusting bearing 71, adjusting roller shaft 72, upper radial nut 73, and lower radial nut 74 to facilitate the placement of the steel pipe 10 onto the feed guide roller 7. After the steel pipe 10 is placed into the feed guide roller 7, the height of the feed guide roller 7 can be raised again by adjusting bearing 71, adjusting roller shaft 72, upper radial nut 73, and lower radial nut 74 until the feed guide roller 7 and the shaping adjusting roller 4 are set on the same horizontal line. This reduces the difficulty of the steel pipe 10 entering the shaping device 2 and improves the working efficiency.

[0048] The positioning device 5 includes a fixed ring 51 and an adjusting ring 52. An adjusting device 6 is provided between the fixed ring 51 and the adjusting ring 52. The adjusting device changes the distance between the fixed ring 51 and the adjusting ring 52. One end of the steel pipe 10 extends between the fixed ring 51 and the adjusting ring 52. Since most steel pipes 10 have a coating on their surface, the coating at the joint ends needs to be removed before the two steel pipes 10 are joined by welding or other methods. When removing the coating at the ends of the steel pipes 10 and completing the joint, the steel pipes 10 need to be firmly fixed to improve the accuracy of the operation. This is to prevent the steel pipes 10 from shaking, swinging, or moving during the coating removal or jointing process, which could lead to inaccurate coating removal depth and damage to the steel pipes 10, or misalignment of the axes of the steel pipes 10 during the jointing process, resulting in gaps or thin joints at the joint. Therefore, the positioning device 5 is used to fix the steel pipes 10 to be joined to improve the accuracy of coating removal and jointing.

[0049] The fixed ring 51 has adjustment grooves 511 at both ends, and one end of the adjustment ring 52 is disposed in the adjustment groove 511. Guide grooves 512 are provided on both sides of the adjustment groove 511, and the adjustment device 6 moves up and down along the guide grooves 512. The adjustment grooves 511 facilitate the adjustment of the adjustment ring 52 by the adjustment device. By changing the relative position between the fixed ring 51 and the adjustment ring 52, the steel pipe 10 can be clamped. This structure can also be used to clamp steel pipes 10 of different diameters.

[0050] Since the steel pipe 10 is cylindrical, the positioning device 5 needs to position the steel pipe 10 around its circumference. Therefore, each positioning device 5 includes two fixing rings 51 and two adjusting rings 52. One end of each fixing ring 51 engages with one adjusting ring 52. The adjusting ring 52 includes a first connecting ring 523 and a second connecting ring 522. One end of the first connecting ring 523 is fixedly connected to the second connecting ring 522. The end of the first connecting ring 523 away from the second connecting ring 522 is engaged with one of the fixing rings 51. The end of the second connecting ring 522 away from the first connecting ring 523 is engaged with the other fixing ring 51. The positioning device 5 comprises a first positioning ring 51, a first adjusting ring 52, a second positioning ring 51, and a second adjusting ring 52 connected in sequence. The first positioning ring 51, the first adjusting ring 52, the second positioning ring 51, and the second adjusting ring 52 form a closed ring. The steel pipe 10 is located in the middle of this ring. Each adjusting ring 52 includes a first connecting ring 523 and a second connecting ring 522.

[0051] To adjust the fixed ring 51 and the adjusting ring 52, changing the diameter formed between them to clamp the steel pipe 10, an adjusting device 6 is used. The adjusting device 6 includes an adjusting bracket 61, a first motor 62, an adjusting screw 63, adjusting blocks 64, a first bevel gear 65, and a second bevel gear 66. The adjusting screw 63 has reverse threads at both ends, and each end of the adjusting screw 63 is threaded with an adjusting block 64. The first motor 62 drives the adjusting screw to rotate, causing the adjusting blocks 64 to move closer or further apart. The adjusting bracket 61 is fixedly mounted on the fixed ring 51, and the first motor 62 is fixedly mounted on the adjusting bracket 61. The output end of the first motor 62 is connected to the first bevel gear 65. The second bevel gear 66 is coaxially fixed with the adjusting screw 63, and the first bevel gear 65 meshes with the second bevel gear 66. Guide blocks 641 are provided on both sides of the adjusting block 64, and each guide block 641 is slidably disposed in each guide groove 512; the adjusting block 64 is provided with a through groove 642, and a connecting rod 643 is provided in the through groove 642. One end of the connecting rod 643 is connected to one end of the adjusting ring 52, and the other end of the connecting rod 643 is provided with a limit block 644. The width of the limit block 644 is greater than the width of the through groove 642.

[0052] Guide blocks 641 are provided on both sides of the adjusting block 64. One end of each guide block 641 slides along the length of the adjusting block 64, and the other end of each guide block 641 slides within each guide groove 512. The adjusting block 64 is provided with a through groove 642, and a connecting rod 643 is provided within the through groove 642. One end of the connecting rod 643 is connected to one end of the adjusting ring 52, and the other end of the connecting rod 643 is provided with a limit block 644. The width of the limit block 644 is greater than the width of the through groove 642. A sliding limit groove 645 is provided on the adjusting block 64, which is provided along the length of the adjusting block 64. One end of each guide block 641 is located within the sliding limit groove 645 and slides along the length of the sliding limit groove 645. When the adjusting block 64 rotates with the adjusting screw 63, the guide block 64 moves, thus fixing the adjusting block 64 and preventing it from being damaged by excessive force from the adjusting screw 63.

[0053] The first motor 62 drives the adjusting screw 63 to rotate. The threads at both ends of the adjusting screw 63 are reversed. Because the two adjusting blocks 64 are set in the adjusting groove 511, when the adjusting screw 63 rotates in the forward or reverse direction, the adjusting blocks 64 that are threaded with the adjusting screw 63 will not rotate with the adjusting screw 63, but will move linearly along the adjusting screw 63 under the action of the adjusting groove 511. The two adjusting blocks 64 will move away from or towards each other. Each adjusting block 64 is provided with a guide block 641 on both sides, and each guide block 641 is slidably set in each guide groove 512. When the adjusting screw 63 drives the adjusting block 64 to move along the adjusting screw 63, the adjusting blocks 64 will move linearly along the adjusting screw 63. When the length of the 3 moves, the adjusting block 64 can move smoothly between the adjusting grooves 511. Since the adjusting block 64 is provided with a through groove 642, and a connecting rod 643 is provided in the through groove 642, one end of the connecting rod 643 is connected to one end of the adjusting ring 52, and the other end of the connecting rod 643 is provided with a limit block 644, when the adjusting block 64 moves, it drives the two adjusting rings 52 to move, changing the distance between the two adjusting rings 52. The change in the distance between the two adjusting rings 52 clamps or loosens the steel pipe 10. By adjusting the distance between the two adjusting rings 52 as needed, steel pipes 10 of different diameters can be clamped.
