Description

Technical Field

[0001] The present invention relates to the technical field of steel processing, and specifically to an anti-oxidation treatment device and process for the surface of 40Cr alloy steel. Background Technique

[0002] The anti-oxidation treatment device for the surface of alloy steel forms a protective oxide film on the metal surface through chemical or electrochemical reactions, preventing the metal from reacting with oxygen in the air and inhibiting the oxidation process. The anti-oxidation treatment improves the corrosion resistance and service life of alloy steel, and is widely used in industries such as aviation, automotive, and construction.

[0003] Chinese Patent with Patent Publication No. CN114351149B discloses an anti-oxidation treatment device for the surface of 40Cr alloy steel during processing, belonging to the technical field of steel processing and treatment equipment. This anti-oxidation treatment device for the surface of 40Cr alloy steel during processing includes a treatment tank body and a servo motor. Two driving mechanisms are arranged inside the treatment tank body, and both of the two driving mechanisms include a driving rotating cylinder, and guiding transmission grooves are circumferentially formed on the outer surfaces of the two driving rotating cylinders. This device can relatively gently ensure that the steel is fully covered with the antioxidant while also accelerating its air-drying rate, greatly improving the treatment efficiency.

[0004] However, the current anti-oxidation treatment device has the following problems: When this anti-oxidation treatment device performs anti-oxidation treatment on a 40Cr alloy steel pipe, air bubbles are likely to be generated inside the pipe of the steel pipe. The existence of air bubbles will cause the anti-oxidation treatment liquid to be unable to uniformly contact the inner surface of the steel pipe, resulting in uneven treatment effects. Some areas may not be effectively protected against oxidation, reducing the quality of the anti-oxidation layer. Therefore, we propose an anti-oxidation treatment device and process for the surface of 40Cr alloy steel. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides an anti-oxidation treatment device and process for the surface of 40Cr alloy steel, which solves the problems raised in the above background technique.

[0006] To achieve the above object, the present invention is realized through the following technical solutions: An anti-oxidation treatment device for the surface of 40Cr alloy steel, including an immersion tank, inside which a treatment device is provided. The treatment device includes a rotating rod rotatably installed inside the immersion tank and driven by a motor. On both outer sides of the rotating rod, notch discs are fixed. Between the two notch discs, a pipe clamping assembly for clamping steel is provided. The pipe clamping assembly includes a number of bidirectional screws rotatably installed circumferentially and uniformly between the two notch discs. On both sides of the bidirectional screw, threaded plates are threadedly connected. On the side where the two threaded plates approach each other, blooming chuck plates are rotatably installed. On the side where the two blooming chuck plates move away from each other, fixing columns are fixed. On the outer sides of the two notch discs away from each other, a number of square rods are fixed circumferentially and uniformly, and the square rods penetrate through the threaded plates. Below the inside of the immersion tank, a turning device is provided. The turning device includes a positioning rod and a number of semi-circular blocks. The positioning rod is fixed to the bottom of the inner wall of the immersion tank. A turning plate is slidably installed on the outer side of the positioning rod, and a spring is provided between the turning plate and the bottom of the inner wall of the immersion tank. One side of the turning plate contacts the inner wall of the immersion tank, and a distance of twenty centimeters is left between the other side of the turning plate and the inner wall of the immersion tank. On both sides of the top of the turning plate, contact rods are fixed. A number of semi-circular blocks are respectively fixed circumferentially and uniformly on the outer sides of the two notch discs. The top of the contact rod is semicircularly arranged, and the semicircular part of the contact rod is on the movement track of the semi-circular block. At the same time, when the notch disc rotates, it drives the semi-circular block to rotate. The semi-circular block pushes the contact rod to drive the turning plate to move downward. When the contact rod no longer pushes the contact rod, the turning plate resets under the action of the corresponding spring elasticity. So on and so forth, thus enabling the turning plate to turn the anti-oxidation treatment liquid in the immersion tank. At the same time, since a distance of twenty centimeters is left between the turning plate and the inner wall of the immersion tank, when the turning plate turns the anti-oxidation treatment liquid, the anti-oxidation treatment liquid will flow from one side of the immersion tank to the other side through the gap between the turning plate and the immersion tank. During this process, the anti-oxidation treatment liquid will flow into the steel pipe through the opening of one side blooming chuck plate, thereby enabling the anti-oxidation treatment liquid to push the bubbles in the steel pipe out of the steel pipe and discharge them through the opening of the blooming chuck plate on the other side.

[0007] According to the above technical solution, a retaining net is fixed to the bottom of the inner wall of the immersion tank. The retaining net is located at the gap between the turning plate and the immersion tank, and at the same time, the retaining net forms a barrier in the flowing direction of the anti-oxidation treatment liquid.

[0008] According to the above technical solution, the processing device further includes a wave convex ring, a plurality of first elastic telescopic rods, a plurality of sleeve plates, and a plurality of first chutes. The plurality of first chutes are respectively and circumferentially and evenly opened on the outer walls of the two notch discs. The plurality of sleeve plates are circumferentially and slidably installed on the outer wall of one of the notch discs. The fixed ends of the plurality of first elastic telescopic rods are respectively and circumferentially and evenly fixed on the sides of the two notch discs close to each other. A connecting rod is slidably installed between the telescopic ends of the two opposite first elastic telescopic rods, and the connecting rod passes through the first chute. The connecting rod penetrates through the sleeve plate, and a spring is arranged between the connecting rod and the sleeve plate. The wave convex ring is fixed on the inner wall of the soaking tank and is located on the side away from the sleeve plate. A plurality of grinding plates are fixed on the outer wall of the connecting rod. A plurality of wavy protrusions are arranged on the upper half of the wave convex ring. One end of the connecting rod away from the sleeve plate is located on the movement track of the wavy protrusions of the wave convex ring. After the steel pipe is placed between the notches of the two notch discs, under the elastic force of the first elastic telescopic rod, the first elastic telescopic rod drives the grinding plate to closely adhere to the outer wall of the steel pipe through the connecting rod. As the notch disc rotates, the notch disc drives the first elastic telescopic rod and the connecting rod to rotate. When the connecting rod moves to the position of the wavy protrusion of the wave convex ring, the wavy protrusion of the wave convex ring pushes the connecting rod to displace along the telescopic ends of the two first elastic telescopic rods, and the spring between the connecting rod and the sleeve plate is stretched. When the wavy protrusion of the wave convex ring no longer pushes the connecting rod, under the elastic force of the corresponding spring between the connecting rod and the sleeve plate, the connecting rod resets. This process is repeated, so that the connecting rod drives the grinding plate to polish the surface of the steel pipe.

[0009] According to the above technical solution, the processing device further includes two friction rings. The two friction rings are respectively fixed on both sides of the inner wall of the soaking tank. The outer wall of the friction ring is in contact with the outer wall of the fixed column. The outer walls of the friction ring and the fixed column are both set as rough surfaces. At the same time, the notch disc drives the threaded plate to rotate through the bidirectional screw rod, and the threaded plate drives the fixed column and the blooming chuck to rotate. Under the frictional force between the fixed column and the friction ring, the friction ring drives the fixed column to rotate, and the fixed column drives the blooming chuck to rotate.

[0010] According to the above technical solution, the processing device further includes a plurality of second chutes, a plurality of second elastic telescopic rods, and two convex rings. The plurality of second chutes are respectively and circumferentially and evenly opened on the outer walls of the two notch discs. The fixed ends of the plurality of second elastic telescopic rods are respectively fixed on the inner walls of the plurality of second chutes. One side of the outer wall of the telescopic end of the second elastic telescopic rod is fixed with a push column. The other side of the outer wall of the telescopic end of the second elastic telescopic rod is hingedly connected to the telescopic end of the first elastic telescopic rod through a hinge rod. The two convex rings are respectively fixed on both sides of the inner wall of the soaking tank. The convex rings are arranged in an irregular circular shape with a smaller upper part and a larger lower part. The push column is in contact with the outer wall of the convex ring. At the same time, the notch disc drives the push column to rotate through the second elastic telescopic rod. When the push column rotates to the lower area of the convex ring, the convex ring pushes the push column to move towards the direction of the second elastic telescopic rod, and the push column squeezes the telescopic end of the second elastic telescopic rod to contract. The telescopic end of the second elastic telescopic rod pushes the hinge rod to drive the telescopic end of the first elastic telescopic rod to stretch. The telescopic end of the first elastic telescopic rod pushes the connecting rod to drive the grinding plate away from the steel pipe, so as to ensure that after the steel pipe enters the anti-oxidation treatment liquid in the soaking tank, the grinding plate no longer contacts the steel pipe.

[0011] A 40Cr alloy steel surface anti-oxidation treatment process for a 40Cr alloy steel surface anti-oxidation treatment device includes the following steps: S1. Place the steel pipe between the notches of the two notch discs, and rotate the bidirectional screw rod. The bidirectional screw rod drives the threaded plate to move along the outside of the square rod towards the center of the rotating rod. S2. The threaded plate drives the blooming chuck to clamp the steel pipe, so as to ensure that the steel pipe is stable between the notches of the two notch discs. Drive the rotating rod to rotate through the motor. The rotating rod drives the notch disc to rotate. The notch disc will drive the steel pipe into the anti-oxidation treatment liquid in the soaking tank. The anti-oxidation treatment liquid reacts with the steel pipe and forms a protective oxide film on the surface of the steel pipe. S3. At the same time, when the notch disc rotates, it will drive the semi-circular block to rotate. The semi-circular block pushes the contact rod to drive the turning plate to move downward. When the contact rod no longer pushes the contact rod, the turning plate resets under the action of the corresponding spring elastic force, and so on, so that the turning plate turns the anti-oxidation treatment liquid in the soaking tank. S4. At the same time, since there is a distance of twenty centimeters between the turning plate and the inner wall of the soaking tank, when the turning plate turns the anti-oxidation treatment liquid, the anti-oxidation treatment liquid will flow from one side of the soaking tank to the other side through the gap between the turning plate and the soaking tank. During this process, the anti-oxidation treatment liquid will flow into the steel pipe through the opening of one side blooming chuck, so that the anti-oxidation treatment liquid pushes the bubbles in the steel pipe out of the steel pipe and discharges them through the opening of the blooming chuck on the other side. S5. Finally, the notch disc will drive the steel pipe out of the anti-oxidation treatment liquid in the soaking tank. At this time, the staff can take out the steel pipe.

[0012] The present invention provides a 40Cr alloy steel surface anti-oxidation treatment device and treatment process, which has the following beneficial effects: (1) The present invention sets a flipping device so that the notched plate, the semicircular block and the abutment rod cooperate to drive the flipping plate to flip the anti-oxidation treatment liquid. The anti-oxidation treatment liquid will flow from one side of the immersion box to the other side through the gap between the flipping plate and the immersion box. The anti-oxidation treatment liquid will flow into the steel pipe through the opening of the flower-shaped clamping plate on one side, so that the anti-oxidation treatment liquid pushes the bubbles in the steel pipe to flow out of the steel pipe and is discharged through the opening of the flower-shaped clamping plate on the other side, thereby reducing the residual bubbles in the steel pipe. The removal of bubbles helps the anti-oxidation treatment liquid to be evenly immersed in each area of ​​the steel pipe, avoiding the inability of certain parts to fully contact the anti-oxidation liquid due to the presence of bubbles. This helps to improve the anti-oxidation effect and ensure that the steel pipe is evenly treated. At the same time, the interception net forms an interception in the flow direction of the anti-oxidation treatment liquid, thereby reducing the rust impurities carried by the anti-oxidation treatment liquid from entering the steel pipe.

[0013] (2) The present invention uses the processing device to enable the elastic telescopic rod, connecting rod, grinding plate, notch plate, and wave raised ring to cooperate with the grinding plate to grind the surface of the steel pipe, thereby avoiding the problem that if there is rust on the surface of the steel pipe, the anti-oxidation film may not be evenly attached, resulting in an uneven film layer; at the same time, the notch plate, bidirectional screw, threaded plate, fixed column, flower chuck, and friction ring cooperate to drive the flower chuck to rotate, so that the flower chuck drives the clamped steel pipe to rotate, thereby ensuring that the surface of the steel pipe can be evenly polished by the grinding plate.

[0014] (3) The present invention cooperates with the notched plate, the second elastic telescopic rod, the push column, the convex ring, and the hinged rod so that the telescopic end of the first elastic telescopic rod pushes the connecting rod to drive the grinding plate away from the steel pipe, thereby ensuring that after the steel pipe enters the anti-oxidation treatment liquid in the immersion box, the grinding plate no longer contacts the steel pipe, thereby avoiding the contact between the grinding plate and the steel pipe, which would block certain areas on the surface of the steel pipe and cause uneven anti-oxidation treatment.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0018] Please refer to Figures 1 - 11, the present invention provides a technical solution: an anti-oxidation treatment device for the surface of 40Cr alloy steel, including an immersion tank 1. A treatment device 2 is arranged inside the immersion tank 1. The treatment device 2 includes a rotating rod 21 which is rotatably installed inside the immersion tank 1 and is driven by a motor. Concave disks 22 are fixed on both outer sides of the rotating rod 21. A pipe clamping assembly for clamping the steel is arranged between the two concave disks 22. The pipe clamping assembly includes a number of bidirectional screws 26 which are circumferentially and rotatably installed between the two concave disks 22. Threaded plates 29 are threadedly connected to both sides of the bidirectional screw 26. Flower chuck disks 210 are rotatably installed on the side where the two threaded plates 29 approach each other. Fixed columns 28 are fixed on the side where the two flower chuck disks 210 are away from each other. A number of square rods 27 are circumferentially and evenly fixed on the side where the two concave disks 22 are away from each other, and the square rods 27 penetrate through the threaded plates 29. A turning device 3 is arranged below the inner part of the immersion tank 1. The turning device 3 includes a positioning rod 31 and a number of semi-circular blocks 35. The positioning rod 31 (as shown in Figure 10 ) is fixed on the bottom of the inner wall of the immersion tank 1. A turning plate 32 is slidably installed on the outside of the positioning rod 31, and a spring is arranged between the turning plate 32 and the bottom of the inner wall of the immersion tank 1. One side of the turning plate 32 contacts the inner wall of the immersion tank 1, and a twenty-centimeter gap is left between the other side of the turning plate 32 and the inner wall of the immersion tank 1. Two contact rods 34 are fixed on both sides of the top of the turning plate 32. A number of semi-circular blocks 35 are respectively circumferentially and evenly fixed on the outside of the two concave disks 22. The top of the contact rod 34 is semicircular, and the semicircular shape of the contact rod 34 is located on the movement track of the semi-circular block 35. Through the setting of the above structure, the turning plate 32 turns the anti-oxidation treatment liquid, and the anti-oxidation treatment liquid will flow from one side of the immersion tank 1 to the other side through the gap between the turning plate 32 and the immersion tank 1. During this process, the anti-oxidation treatment liquid will flow into the steel pipe through the opening of one side of the flower chuck disk 210, so that the anti-oxidation treatment liquid can push the air bubbles in the steel pipe out of the steel pipe and discharge them through the opening of the flower chuck disk 210 on the other side, thereby reducing the residue of air bubbles in the steel pipe. The removal of air bubbles helps the anti-oxidation treatment liquid to evenly penetrate into each area inside the steel pipe, avoiding the situation that some parts cannot fully contact the anti-oxidation liquid due to the existence of air bubbles. This helps to improve the anti-oxidation effect and ensure that the steel pipe is evenly treated.

[0019] A retaining net 33 is fixed on the bottom of the inner wall of the immersion tank 1, and the retaining net 33 is located at the gap between the turning plate 32 and the immersion tank 1. Through the setting of the above structure, the retaining net 33 forms an interception in the flowing direction of the anti-oxidation treatment liquid, thereby reducing the rust impurities carried in the anti-oxidation treatment liquid from entering the steel pipe.

[0020] The processing device 2 further includes a wave convex ring 212, a number of first elastic telescopic rods 23, a number of sleeve plates 241, and a number of first chutes 213. The number of first chutes 213 are respectively and circumferentially and evenly arranged on the outer walls of the two notch discs 22. The number of sleeve plates 241 are circumferentially and evenly slidably mounted on the outer wall of one of the notch discs 22. The fixed ends of the number of first elastic telescopic rods 23 are respectively and circumferentially and evenly fixed on the sides of the two notch discs 22 close to each other. A connecting rod 24 is slidably mounted between the telescopic ends of two opposite first elastic telescopic rods 23, and the connecting rod 24 passes through the first chute 213. The connecting rod 24 penetrates through the sleeve plate 241, and a spring is provided between the connecting rod 24 and the sleeve plate 241. The wave convex ring 212 is fixed on the inner wall of the soaking tank 1, and the wave convex ring 212 is located on the side away from the sleeve plate 241. A number of grinding plates 25 are fixed on the outer wall of the connecting rod 24. A number of wave-shaped protrusions are provided on the upper half of the wave convex ring 212. One end of the connecting rod 24 away from the sleeve plate 241 is located on the movement track of the wave-shaped protrusions of the wave convex ring 212. Through the setting of the above structure, the connecting rod 24 drives the grinding plate 25 to polish the surface of the steel pipe, thereby avoiding the problem that if there is rust on the surface of the steel pipe, the anti-oxidation film may not be evenly attached, resulting in uneven film layer.

[0021] The processing device 2 further includes two friction rings 211. The two friction rings 211 are respectively fixed on both sides of the inner wall of the soaking tank 1. The outer wall of the friction ring 211 is in contact with the outer wall of the fixed column 28. The outer walls of the friction ring 211 and the fixed column 28 are both set as rough surfaces. Through the setting of the above structure, under the action of the frictional force between the fixed column 28 and the friction ring 211, the friction ring 211 drives the fixed column 28 to rotate, and the fixed column 28 drives the blooming chuck 210 to rotate, so that the blooming chuck 210 drives the clamped steel pipe to rotate, thereby ensuring that the surface of the steel pipe can be evenly polished by the grinding plate 25.

[0022] The processing device 2 further includes a plurality of second sliding grooves 214, a plurality of second elastic telescopic rods 215, and two convex rings 217. The plurality of second sliding grooves 214 are respectively and circumferentially and evenly formed on the outer walls of the two notch discs 22. The fixed ends of the plurality of second elastic telescopic rods 215 are respectively fixed on the inner walls of the plurality of second sliding grooves 214. One side of the outer wall of the telescopic end of the second elastic telescopic rod 215 is fixed with a push column 216. The other side of the outer wall of the telescopic end of the second elastic telescopic rod 215 and the telescopic end of the first elastic telescopic rod 23 are hingedly connected through a hinge rod 218. The two convex rings 217 are respectively fixed on both sides of the inner wall of the soaking tank 1. The convex ring 217 is arranged in an irregular circular shape with a smaller upper part and a larger lower part. The push column 216 is in contact with the outer wall of the convex ring 217. Through the setting of the above structure, the telescopic end of the first elastic telescopic rod 23 pushes the connecting rod 24 to drive the grinding plate 25 away from the steel pipe, so as to ensure that after the steel pipe enters the anti-oxidation treatment liquid in the soaking tank 1, the grinding plate 25 no longer contacts the steel pipe, thus avoiding the problem that when the grinding plate 25 contacts the steel pipe, the grinding plate 25 will block some areas on the surface of the steel pipe, resulting in uneven anti-oxidation treatment.

[0023] When in use, the steel pipe is placed between the notches of the two notch plates 22, and the staff manually rotates the bidirectional screw 26, which drives the threaded plate 29 to move along the outside of the square rod 27 toward the center of the rotating rod 21, and the threaded plate 29 drives the flower clamping plate 210 to clamp the steel pipe, thereby ensuring that the steel pipe is stably between the notches of the two notch plates 22, and the rotating rod 21 is driven by the motor to rotate, and the rotating rod 21 drives the notch plate 22 to rotate, and the notch plate 22 drives the steel pipe into The anti-oxidation treatment liquid in the immersion box 1 reacts with the steel pipe and forms a protective oxide film on the surface of the steel pipe. At the same time, when the notched plate 22 rotates, the semicircular block 35 is driven to rotate, and the semicircular block 35 pushes the resistance rod 34 to drive the flip plate 32 to move downward. When the semicircular block 35 no longer pushes the resistance rod 34, the flip plate 32 is reset under the action of the corresponding spring force, and so on and so forth, so that the flip plate 32 flips the anti-oxidation treatment liquid in the immersion box 1 At the same time, since there is a twenty-centimeter gap between the flip plate 32 and the inner wall of the immersion box 1, when the flip plate 32 flips the anti-oxidation treatment liquid, the anti-oxidation treatment liquid will flow from one side of the immersion box 1 to the other side through the gap between the flip plate 32 and the immersion box 1. In this process, the anti-oxidation treatment liquid will flow into the steel pipe through the opening of the flowering chuck 210 on one side, so that the anti-oxidation treatment liquid pushes the bubbles in the steel pipe to flow out of the steel pipe and is discharged through the opening of the flowering chuck 210 on the other side, thereby reducing the residual bubbles in the steel pipe. The removal of bubbles helps the anti-oxidation treatment liquid to be evenly immersed in each area of ​​the steel pipe, avoiding the inability of certain parts to fully contact the anti-oxidation liquid due to the presence of bubbles, which helps to improve the anti-oxidation effect and ensure that the steel pipe is evenly treated. At the same time, the interception net 33 forms an interception in the flow direction of the anti-oxidation treatment liquid, thereby reducing the rust impurities carried in the anti-oxidation treatment liquid from entering the steel pipe.

[0024] After the steel pipe is placed between the notches of the two notch plates 22, under the elastic force of the elastic telescopic rod 1 23, the elastic telescopic rod 1 23 will drive the grinding plate 25 to cling to the outer wall of the steel pipe through the connecting rod 24. As the notch plate 22 rotates, the notch plate 22 drives the elastic telescopic rod 1 23 and the connecting rod 24 to rotate. When the connecting rod 24 moves to the wavy raised position of the wavy raised ring 212, the wavy raised ring 212 pushes the connecting rod 24 along the two elastic telescopic rods 1. The telescopic end of 23 is displaced, and the spring between the connecting rod 24 and the sleeve plate 241 is stretched. When the wavy protrusion of the wavy protrusion ring 212 no longer pushes the connecting rod 24, the connecting rod 24 is reset under the action of the corresponding spring force between the connecting rod 24 and the sleeve plate 241, and so on. As a result, the connecting rod 24 drives the grinding plate 25 to grind the surface of the steel pipe, thereby avoiding the problem that if there is rust on the surface of the steel pipe, the anti-oxidation film may not be able to adhere evenly, resulting in an uneven film layer.

[0025] Meanwhile, the notch disc 22 drives the threaded plate 29 to rotate through the bidirectional screw 26. The threaded plate 29 drives the fixed column 28 and the blooming chuck 210 to rotate. Under the frictional force between the fixed column 28 and the friction ring 211, the friction ring 211 drives the fixed column 28 to rotate, and the fixed column 28 drives the blooming chuck 210 to rotate. Thus, the blooming chuck 210 drives the clamped steel pipe to rotate, ensuring that the surface of the steel pipe can be evenly polished by the polishing plate 25.

[0026] Meanwhile, the notch disc 22 drives the push column 216 to rotate through the elastic telescopic rod two 215. When the push column 216 rotates to the lower area of the convex ring 217, the convex ring 217 pushes the push column 216 to move in the direction of the elastic telescopic rod two 215, and the push column 216 squeezes the telescopic end of the elastic telescopic rod two 215 to contract. The telescopic end of the elastic telescopic rod two 215 pushes the articulated rod 218 to drive the telescopic end of the elastic telescopic rod one 23 to stretch. The telescopic end of the elastic telescopic rod one 23 pushes the connecting rod 24 to drive the polishing plate 25 away from the steel pipe. Thus, after the steel pipe enters the anti-oxidation treatment liquid in the soaking tank 1, the polishing plate 25 no longer contacts the steel pipe, avoiding the problem that the polishing plate 25 contacts the steel pipe and blocks some areas on the surface of the steel pipe, resulting in uneven anti-oxidation treatment.

[0027] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.

A 40Cr alloy steel surface anti-oxidation treatment process for a 40Cr alloy steel surface anti-oxidation treatment device, comprising a 40Cr alloy steel surface anti-oxidation treatment device as described in any one of claims 1-9, characterized in that, Including the following steps: S1. Place the steel pipe between the notches of the two notch discs (22), rotate the bidirectional screw rod (26), and the bidirectional screw rod (26) drives the threaded plate (29) to move along the outside of the square rod (27) towards the center of the rotating rod (21). S2, the threaded plate (29) drives the flower clamping plate (210) to clamp the steel pipe, thereby ensuring that the steel pipe is stably located between the notches of the two notched plates (22), and the motor drives the rotating rod (21) to rotate, and the rotating rod (21) drives the notched plate (22) to rotate, and the notched plate (22) drives the steel pipe into the anti-oxidation treatment liquid in the immersion box (1), and the anti-oxidation treatment liquid reacts with the steel pipe and forms a protective oxide film on the surface of the steel pipe; S3. When the notched plate (22) rotates, the semicircular block (35) is driven to rotate. The semicircular block (35) pushes the abutment rod (34) to drive the flip plate (32) to move downward. When the abutment rod (34) no longer pushes the abutment rod (34), the flip plate (32) is reset under the action of the corresponding spring force. This is repeated, so that the flip plate (32) flips the anti-oxidation treatment liquid in the soaking box (1). S4. At the same time, since there is a twenty-centimeter gap between the flip plate (32) and the inner wall of the immersion box (1), when the flip plate (32) flips the anti-oxidation treatment liquid, the anti-oxidation treatment liquid will flow from one side of the immersion box (1) to the other side through the gap between the flip plate (32) and the immersion box (1). In this process, the anti-oxidation treatment liquid will flow into the steel pipe through the opening of the flowering chuck (210) on one side, so that the anti-oxidation treatment liquid pushes the bubbles in the steel pipe to flow out of the steel pipe and is discharged through the opening of the flowering chuck (210) on the other side; S5. Finally, the notched plate (22) drives the steel pipe to move out of the anti-oxidation treatment liquid in the immersion box (1), and the staff takes out the steel pipe.
