Description

Technical Field

[0002] In the process of processing and manufacturing steel pipes, it is necessary to straighten the steel pipes through straightening equipment. During straightening, the friction between the steel pipes and the straightening rollers will generate a large amount of frictional heat. In order to control this heat and avoid deformation or damage of the steel pipes due to excessive heating, manufacturers often use flushing methods to reduce the temperature of the steel pipes and ensure the smooth progress of the straightening process. In addition, flushing can also help clean the surface of the steel pipes, remove iron filings and impurities generated during the straightening process, and further improve the quality of straightening. However, the existing flushing methods are mostly to directly place water pipes on the straightening equipment, very close to the straightening rollers. When the straightening rollers straighten the steel pipes, it is easy for the water pipes to be drawn in, resulting in accidents and losses, and affecting the processing and production of steel pipes. In order to drain the water on the straightening equipment, a narrow drainage trough will be opened on the straightening equipment.

DETAILED DESCRIPTION

[0028] 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.

[0029] See also Figure 1 - Fig. 9A leveling and straightening device and a straightening method for steel pipe processing, comprising a straightening table 1 and a collecting trough 11 disposed on the periphery of the straightening table 1 and a drainage trough 12 disposed in the middle of the straightening table 1, the straightening table 1 being provided with a straightening mechanism 2, a flushing assembly 7 and a cleaning assembly 8, the straightening mechanism 2 comprising a plurality of vertical straightening assemblies 3 evenly arranged on the surface of the straightening table 1, and also comprising a horizontal straightening assembly 5 corresponding to one side of each vertical straightening assembly 3, and flushing assemblies 7 are disposed on both sides of each vertical straightening assembly 3, the vertical straightening assembly 3 comprising a fixing frame 31, an upper pressure roller seat 32 and a lower pressure roller seat 33, the upper pressure roller seat 32 and the lower pressure roller seat 33 being sequentially disposed on the fixing frame 31, and the upper pressure roller seat 32 and the lower pressure roller seat 33 A vertical pressure roller 34 is installed on each of them. The upper pressure roller seat 32 can drive the vertical pressure roller 34 thereon to move on the fixed frame 31. The flushing assembly 7 includes a flushing head 75. The flushing head 75 is rotatably set on the upper pressure roller seat 32 and cooperates with the fixed frame 31. When the upper pressure roller seat 32 moves, it drives the flushing head 75 to rotate a corresponding angle on the fixed frame 31. The cleaning assembly 8 includes a transmission belt 82 and a scraper 83. The transmission belt 82 is set in the drainage trough 12 and cooperates with the vertical pressure roller 34 on the lower pressure roller seat 33. A plurality of scrapers 83 are evenly arranged on the outside of the transmission belt 82. When the vertical pressure roller 34 on the lower pressure roller seat 33 rotates, it drives the transmission belt 82, and the transmission belt 82 scrapes out debris and water in the drainage trough 12 through the scraper 83.

[0030] When in use, the device is placed in a steel pipe production line. Initially, the vertical straightening assembly 3 is in an initial state, the upper roller seat 32 is located at the lower end of the fixed frame 31, and the vertical roller 34 thereon is against the vertical roller 34 on the lower roller seat 33. At this time, the flushing head 75 of the flushing assembly 7 is tilted at a certain angle toward the vertical roller 34 and aligned between the upper and lower rollers. The horizontal straightening assembly 5 is also in an initial state. Before straightening the steel pipe, the vertical straightening assembly 3 and the horizontal straightening assembly 5 need to be adjusted accordingly according to the diameter of the steel pipe produced by the production line. The vertical straightening assembly 3 is adjusted. When the distance between the upper and lower vertical rollers 34 corresponds to the diameter of the steel pipe produced by the production line, the upper roller seat 32 stops moving. In this process, the movement of the upper roller seat 32 drives the flushing head 75 to deflect away from the vertical roller 34 by a corresponding angle to ensure that the flushing head 75 can flush the water onto the steel pipe. After the vertical correction component 3 is adjusted, the horizontal correction component 5 is adjusted accordingly. When the vertical correction component 3 and the horizontal correction component 5 are adjusted, the steel pipes on the production line are started to be sent. The incoming steel pipe is straightened. When the straightening mechanism 2 straightens the steel pipe, the steel pipe first enters the vertical straightening assembly 3 and passes between the upper and lower rotating vertical pressure rollers 34. During this process, the vertical pressure roller 34 straightens the steel pipe in the vertical direction and transports the steel pipe to the next vertical straightening assembly 3. Before the steel pipe enters the vertical straightening assembly 3, it will be flushed by the flushing head 75 to keep the steel pipe clean before straightening. When the steel pipe passes through the vertical straightening assembly 3, the steel pipe will be flushed by another flushing head 75 to cool and clean the steel pipe. Then the steel pipe enters the horizontal straightening assembly 5 and is horizontally straightened. During the process of transitioning the steel pipe to the next vertical correction component 3, the correction component 5 corrects the steel pipe in the horizontal direction. After passing through the horizontal correction component 5, the steel pipe is again flushed and cooled by the flushing head 75 before entering the next vertical correction component 3. Among them, most of the water flow from the flushing head 75 to flush the steel pipe will carry the debris on the steel pipe and fall into the drainage trough 12 of the straightening table 1 below. When the vertical correction component 3 is running, the vertical pressure roller 34 on the lower pressure roller seat 33 will drive the transmission belt 82 to rotate, and the rotating transmission belt 82 will scrape the debris and water in the drainage trough 12 out of the drainage trough 12 through the scraper 83.

[0031] The difference from the above-mentioned embodiment is that the fixed frame 31 is fixedly installed on the straightening table 1, the side wall of the fixed frame 31 is fixedly connected with a slide rail 311, the lower pressure roller seat 33 is fixedly installed on the bottom of the fixed frame 31, the upper pressure roller seat 32 is slidably installed on the slide rail 311, and racks 312 are provided on both sides of the fixed frame 31, and the racks 312 are fixedly connected to the upper end of the fixed frame 31, and the vertical pressure roller 34 is rotatably installed on the upper pressure roller seat 32 and the lower pressure roller seat 33 through a rotating shaft, and one end of the rotating shaft of each vertical pressure roller 34 is coaxially fixed with a transmission gear 341, wherein the rotating shafts of the vertical pressure rollers 34 on the first upper pressure roller seat 32 and the last lower pressure roller seat 33 are coaxially fixed with auxiliary pulleys 342, and the auxiliary pulleys 342 are located between the side of the vertical pressure roller 34 and the inner side of the fixed frame 31.

[0032] Among them, when adjusting the vertical straightening component 3, by rotating the adjusting screw 35 in the forward direction, the adjusting screw 35 drives the upper pressure roller seat 32 to move upward along the slide rail 311 in the fixed frame 31, so that the vertical pressure roller 34 on the upper pressure roller seat 32 is separated from the vertical pressure roller 34 on the lower pressure seat by a corresponding distance. When straightening the steel pipe, the vertical pressure roller 34 on the lower pressure roller seat 33 drives the vertical pressure roller 34 on the upper pressure roller seat 32 to rotate, straighten the steel pipe, and drive the secondary pulley 342 thereon to rotate.

[0033] The difference from the above embodiment is that the vertical straightening assembly 3 also includes an adjusting screw 35, a driving motor 36, a fixing plate 37 and a connecting piece 38, the lower end of the adjusting screw 35 is rotatably mounted on the top of the upper pressure roller seat 32, the upper end of the adjusting screw 35 passes through the upper side of the fixing frame 31, the driving motor 36 is located on one side of the straightening table 1, and the output shaft of the driving motor 36 is coaxially fixedly connected with one end of the rotating shaft of the vertical pressure roller 34 on the lower pressure roller seat 33 through a coupling;

[0034] The fixing plate 37 is fixedly installed on one side of the fixing frame 31 and is located between the upper pressure roller seat 32 and the lower pressure roller seat 33. A driving screw 371 is rotatably installed on the fixing plate 37. The connecting member 38 is assembled on the driving screw 371 through a thread, and the connecting member 38 and the fixing plate 37 are slidably matched. A gear seat 381 is slidably installed in the connecting member 38. A supporting spring 382 is fixedly connected between the bottom side of the gear seat 381 and the bottom inside the connecting member 38. Auxiliary gears 39 are rotatably installed on the upper and lower sides of the gear seat 381. The two auxiliary gears 39 are meshed with each other, located on one side of the transmission gear 341, and are respectively meshed with one transmission gear 341.

[0035] After the upper pressure roller seat 32 is adjusted, the drive screw 371 is rotated by a wrench to drive the connecting member 38, so that the connecting member 38 moves with the auxiliary gear 39 on the fixing plate 37 between the upper and lower transmission gears 341, and the auxiliary gear 39 located on the lower side of the connecting member 38 moves to the upper side of the bottom transmission gear 341 to mesh with it. During this process, the bottom transmission gear 341 lifts the lower auxiliary gear 39 and the gear seat 381, so that the gear seat 381 slides upward in the connecting member 38, and the upper auxiliary gear 39 is meshed with the upper transmission gear 341. The bottom engages and stretches the supporting spring 382. The stretched supporting spring 382 pulls the gear seat 381 downward, so that the auxiliary gear 39 on the lower side is tightly engaged with the transmission gear 341 on the bottom side. After the auxiliary gear 39 is engaged with the transmission gear 341, the driving screw 371 is stopped. When straightening the steel pipe, the driving motor 36 drives the vertical pressure roller 34 on the lower pressure roller seat 33 to rotate through the connecting shaft. The rotating vertical pressure roller 34 on the lower pressure roller seat 33 drives the vertical pressure roller 34 on the upper pressure roller seat 32 to rotate through the cooperation between the transmission gear 341 and the auxiliary gear 39.

[0036] The difference from the above embodiment is that the flushing assembly 7 also includes a connecting seat 71, a rotating sleeve 72 and a water pipe 73. The two connecting seats 71 are respectively fixedly connected to the two sides of the top of the upper pressure roller seat 32. The rotating sleeve 72 is rotatably installed on the connecting seat 71. An adjusting gear 721 is coaxially fixedly connected to the outer side of one end of the rotating sleeve 72. The adjusting gear 721 is meshed with the rack 312. The water pipe 73 is fixedly installed in the rotating sleeve 72. The two ends of the water pipe 73 extend from the two sides of the rotating sleeve 72, one end of which is fixedly connected to the water pipe interface 74. The flushing head 75 is fixedly connected to the other end of the water pipe 73.

[0037] Before the equipment is started, the water pipe interface 74 is connected to the water pipe for conveying water. When the upper pressure roller seat 32 moves upward, the upper pressure roller seat 32 drives the rotating sleeve 72 to move synchronously through the connecting seat 71. During the movement of the rotating sleeve 72, the adjusting gear 721 drives the rotating sleeve 72 to rotate in the connecting seat 71 with the cooperation of the rack 312, so that the flushing head 75 on the rotating sleeve 72 is deflected accordingly. When the steel pipe starts to be straightened, the water pipe conveys water into the water pipe 73, and the flushing head 75 flushes the water in the water pipe 73 to the steel pipe below.

[0038] The difference from the above embodiment is that a transmission groove 13 is provided at both ends of the straightening table 1, and the two transmission grooves 13 are respectively located below the first fixed frame 31 and the last fixed frame 31 on the straightening table 1. A sewage outlet 14 is provided in the collecting groove 11, and the sewage outlet 14 is located at one end of the straightening table 1, corresponding to the drainage groove 12.

[0039] When straightening the steel pipe, some water will splash out of the drain trough 12. Part of the water splashed out of the drain trough 12 will flow back to the drain trough 12, and the other part will flow into the collecting trough 11, ensuring that the sewage after flushing the steel pipe will not flow into the working environment. Finally, the sewage in the collecting trough 11 and the drain trough 12 will converge into the sewage outlet 14 and be discharged from the sewage outlet 14.

[0040] The difference from the above embodiment is that the cleaning component 8 also includes a transmission roller 81, and a plurality of transmission rollers 81 are evenly rotated and installed in the drainage groove 12. One end of the transmission roller 81 located in the transmission groove 13 is coaxially fixedly connected with a driven pulley 811, and the driven pulley 811 is connected to the auxiliary pulley 342 through a transmission belt 4. Both sides of the transmission roller 81 are equipped with transmission belts 82, and both ends of the scraper 83 are respectively fixedly connected to a transmission belt 82. The scraper 83 fits with the drainage groove 12. When the scraper 83 is facing downward, the bottom of the scraper 83 is in contact with the bottom of the drainage groove 12.

[0041] When the secondary pulley 342 rotates, the driven pulley 811 is driven to rotate through the transmission belt 4, so that the driven pulley 811 drives the transmission belt 82 to rotate in the drainage trough 12 through the transmission roller 81 thereon, and the scraper 83 under the transmission belt 82 scrapes the debris and water in the drainage trough 12 toward the sewage outlet 14.

[0042] The difference from the above-mentioned embodiment is that the horizontal correction component 5 includes a mounting seat 51, a threaded rod 52, and a sliding block 53. The mounting seat 51 is fixedly installed on the straightening table 1 and is located on one side of the fixed frame 31. The threaded rod 52 is rotatably installed in the mounting seat 51. The threads at both ends of the threaded rod 52 are in opposite directions. One end of the threaded rod 52 extends out from the mounting seat 51. Two limiting slide bars 511 are fixedly connected in the mounting seat 51. The two limiting slide bars 511 are respectively located on both sides of the threaded rod 52. The two sliding blocks 53 are respectively assembled on the two ends of the threaded rod 52 by threads, and the two sides of the sliding blocks 53 are slidably installed on the limiting slide bars 511. An accordion-type shield 54 is provided on the upper end of the mounting seat 51, and the two ends of the accordion-type shield 54 are respectively fixedly connected to the two ends of the mounting seat 51.

[0043] In the initial state, the two sliding blocks 53 on the threaded rod 52 are located in the middle of the mounting seat 51, and the two horizontal pressure rollers 56 thereon are against each other. When adjusting the horizontal correction component 5, firstly tighten the locking bolt 58 to make the locking bolt 58 end the interference restriction on the support shaft 55, and then rotate the threaded rod 52 in the opposite direction, so that the threaded rod 52 drives the two sliding blocks 53 to move toward the two ends of the mounting seat 51 under the guidance of the limiting slide bar 511, and open the two horizontal pressure rollers 56 against each other. In this process, the accordion shield 54 on the mounting seat 51 will be extended and retracted accordingly. The horizontal rollers 56 are compressed to ensure that the sewage mixed with debris will not fall into the mounting seat 51 when flushing the steel pipe, and the debris in the sewage is prevented from falling into the mounting seat 51 and affecting the normal use of the horizontal correction component 5. After adjusting the spacing between the horizontal pressure rollers 56, stop rotating the threaded rod 52 and tighten the locking bolt 58 so that the locking bolt 58 contacts the support shaft 55 to prevent the support shaft 55 from driving the horizontal pressure roller 56 to move when straightening the steel pipe. After the steel pipe passes through the vertical correction component 3, it will pass between the two horizontal pressure rollers 56, and the horizontal pressure roller 56 will correct the steel pipe from the horizontal direction.

[0044] The difference from the above-mentioned embodiment is that the horizontal correction component 5 also includes a support shaft 55, a horizontal pressure roller 56 and a limit frame 57. The bottom of the support shaft 55 is fixedly connected to the sliding block 53 and passes through the accordion-type shield 54. A horizontal pressure roller 56 is rotatably mounted on the support shaft 55, and the horizontal pressure roller 56 corresponds to the vertical pressure roller 34. The limit frame 57 is fixedly connected to the mounting seat 51. A slot is provided at the upper end of the limit frame 57, and the top end of the support shaft 55 is located in the slot. A locking bolt 58 is installed on the side of the limit frame 57, and one end of the locking bolt 58 abuts against the side of the support shaft 55.

[0045] The difference from the above-mentioned embodiment is that the top end of the adjusting screw rod 35 , the protruding end of the threaded rod 52 and one end of the driving screw rod 371 are all equipped with an adjusting nut 6 .

[0046] When it is necessary to rotate the adjusting screw 35, the threaded rod 52 and the driving screw 371, the adjusting nut 6 on the adjusting screw 35, the threaded rod 52 and the driving screw 371 is turned by a wrench, so that the adjusting nut 6 drives the adjusting screw 35, the threaded rod 52 and the driving screw 371 to rotate.

[0047] The invention discloses a correction method for steel pipe processing, which uses a leveling correction device.

[0048] Working principle: When in use, the equipment is placed in the steel pipe production line. Initially, the vertical straightening component 3 and the horizontal straightening component 5 are both in the initial state. The upper pressure roller seat 32 of the vertical straightening component 3 is located at the lower end of the fixed frame 31, and the vertical pressure roller 34 thereon is against the vertical pressure roller 34 on the lower pressure roller seat 33. At this time, the flushing head 75 of the flushing component 7 is inclined at a certain angle toward the vertical pressure roller 34 and aligned between the upper and lower pressure rollers. The two sliding blocks 53 on the threaded rod 52 of the horizontal straightening component 5 are located in the middle of the mounting seat 51, and the two horizontal pressure rollers 56 thereon are against each other. Before straightening the steel pipe, it is necessary to adjust the vertical straightening component 3 and the horizontal straightening component 5 accordingly by using a wrench to rotate the adjusting nut 6 according to the diameter of the steel pipe produced by the production line. When adjusting the vertical correction component 3, by rotating the adjusting screw rod 35 in the forward direction, the adjusting screw rod 35 drives the upper pressure roller seat 32 to move upward along the slide rail 311 in the fixed frame 31, so that the vertical pressure roller 34 on the upper pressure roller seat 32 is separated from the vertical pressure roller 34 on the lower pressure seat by a corresponding distance, and the upper pressure roller seat 32 stops moving. In this process, as the upper pressure roller seat 32 moves, the upper pressure roller seat 32 drives the rotating sleeve 72 to move synchronously through the connecting seat 71. During the movement of the rotating sleeve 72, the adjusting gear 721 drives the rotating sleeve 72 to rotate in the connecting seat 71 with the cooperation of the rack 312, so that the flushing head 75 on the rotating sleeve 72 is deflected accordingly, ensuring that the flushing head 75 can flush the water flow onto the steel pipe, and then the water pipe interface 74 is connected to the water pipe for conveying water;

[0049] After the upper pressure roller seat 32 is adjusted, the drive screw 371 is rotated by a wrench to drive the connecting piece 38, so that the connecting piece 38 moves with the auxiliary gear 39 on the fixed plate 37 between the upper and lower transmission gears 341, and the auxiliary gear 39 located on the lower side of the connecting piece 38 will move to the upper side of the bottom transmission gear 341 and mesh with it. During this process, the transmission gear 341 on the bottom side will lift the auxiliary gear 39 and the gear seat 381 on the lower side, so that the gear seat 381 slides upward in the connecting piece 38, meshing the upper auxiliary gear 39 with the bottom of the upper transmission gear 341, and stretching the support spring 382. The stretched support spring 382 pulls the gear seat 381 downward, so that the auxiliary gear 39 on the lower side is tightly meshed with the transmission gear 341 on the bottom side. After the auxiliary gear 39 is meshed with the transmission gear 341, stop rotating the drive screw. 371. When adjusting the horizontal correction component 5, first tighten the locking bolt 58 so that the locking bolt 58 ends the interference restriction on the support shaft 55, and then rotate the threaded rod 52 in the opposite direction so that the threaded rod 52 drives the two sliding blocks 53 to move toward the two ends of the mounting seat 51 under the guidance of the limiting sliding rod 511, and opens the two horizontal pressure rollers 56 that are against each other. In this process, the accordion-type shield 54 on the mounting seat 51 will be extended and retracted accordingly to ensure that the sewage mixed with debris will not fall into the mounting seat 51 when flushing the steel pipe, so as to avoid the debris in the sewage falling into the mounting seat 51 and affecting the normal use of the horizontal correction component 5. After adjusting the spacing between the horizontal pressure rollers 56, stop rotating the threaded rod 52 and tighten the locking bolt 58 so that the locking bolt 58 is in contact with the support shaft 55 to prevent the support shaft 55 from driving the horizontal pressure roller 56 to move when straightening the steel pipe.

[0050] After the straightening mechanism 2 is adjusted, the steel pipe sent from the production line is straightened. When straightening the steel pipe, the driving motor 36 drives the vertical pressure roller 34 on the lower pressure roller seat 33 to rotate through the connecting shaft. The rotating vertical pressure roller 34 on the lower pressure roller seat 33 drives the vertical pressure roller 34 on the upper pressure roller seat 32 to rotate through the cooperation between the transmission gear 341 and the auxiliary gear 39, and drives the secondary pulley 342 thereon to rotate. The water pipe transports water into the water pipe 73. The steel pipe first enters the vertical correction component 3 and passes between the upper and lower rotating vertical pressure rollers 34. In this process, the vertical pressure roller 34 corrects the steel pipe in the vertical direction. Before the steel pipe enters the vertical correction component 3, the flushing head 75 flushes the water in the water pipe 73 to the steel pipe below. The steel pipe is flushed by the flushing head 75 to keep the steel pipe clean before straightening. When the steel pipe passes through the vertical correction component 3, the steel pipe will be flushed again by another flushing head 75 to cool and clean the steel pipe, and then the steel pipe enters the horizontal correction component 5. The horizontal correction component 5 corrects the steel pipe in the horizontal direction during the transition to the next vertical correction component 3. After the steel pipe passes through the horizontal correction component 5, it will be flushed and cooled by the flushing head 75 again before entering the next vertical correction component 3. Among them, most of the water flow flushing the steel pipe by the flushing head 75 will be mixed with debris on the steel pipe and fall into the drainage trough 12 of the straightening table 1 below. When the vertical correction component 3 is running, the secondary pulley 342 drives the driven pulley 811 to rotate through the transmission belt 4, so that the driven pulley 811 drives the transmission belt 82 to rotate in the drainage trough 12 through the transmission roller 81 thereon, and the scraper 83 under the transmission belt 82 scrapes the debris and water in the drainage trough 12 to the sewage outlet 14.
