Description

Technical Field

[0001] The present invention relates to the technical field of stainless steel welded pipe solution treatment, and specifically to an on-line bright solution treatment device for stainless steel welded pipes. Background Art

[0002] Due to its good corrosion resistance, high strength and good appearance, stainless steel welded pipes are widely used in many fields such as petroleum, chemical industry, food, medicine, construction, and automobile manufacturing. For example, in the petrochemical industry, stainless steel welded pipes are needed to transport various corrosive media; in the food and medicine industries, where high hygiene requirements are imposed, stainless steel welded pipes are widely used because of their characteristics of not being prone to rust and being easy to clean.

[0003] When the traditional device needs to polish the surface of the welding joint during use, it requires manual polishing by workers, and after polishing, the pipe wall also needs to be cleaned to ensure stability during welding. This method not only reduces the welding efficiency but also increases the complexity of the work. At the same time, if the weld of the stainless steel pipe after welding is not effectively processed in time, it may cause cracks in the stainless steel pipe due to stress at the weld, thus increasing the risk of later use. Summary of the Invention

[0004] After the stainless steel pipe is polished by the invention, the stainless steel pipe will gradually move as the first support moves. At the same time, after air enters the inside of the nozzle, it will be released upward to clean the outer wall of the polished stainless steel pipe, thus preventing the residual polishing residue on the outer wall from affecting the welding effect. At the same time, after welding is completed, the nozzle will also cool the welded area, and the polishing roller will also polish the welded area, making the welded area smoother and reducing the stress generated by welding.

[0008] Preferably, one end of the gear A is movably connected with a fixing rod, and the connecting shaft penetrates through the gear A. The gear A is fixed by being fixedly connected with the first support through the fixing rod. The rack A is meshed and connected to the outside of the gear A, and the rack A is fixedly connected with the base.

[0009] Preferably, the first support is fixedly connected with a rack B on the opposite side of the fixing rod. A connecting pipe A is fixedly connected to the upper end of the base. The outside of the connecting pipe A is provided with the rack B. One end of the rack B close to the connecting pipe A is fixedly connected with a connecting rod. The connecting rod penetrates through the connecting pipe A and extends to the inside to be connected with a valve. One end of the connecting pipe A is fixedly connected with a nozzle, and the other end is connected with a fan.

[0010] Preferably, one end of the reciprocating screw rod away from the motor A is fixedly connected with a pulley A. A belt is sleeved inside the pulley A. One end of the belt away from the pulley A is sleeved with a pulley B. One end of the pulley B close to the second support is fixedly connected with a grinding roller, and the grinding roller is located inside the second support.

[0011] Preferably, the detection ring is fixed by being connected with the base. A plurality of groups of springs are fixedly connected to the outside of the detection ring. One end of each of the plurality of groups of springs is fixedly connected with a movable rod, and the movable rod penetrates through the detection ring and extends to the inside.

[0012] Preferably, the limiting ring is fixedly connected with the base. A motor B is fixedly connected to one side of the base. The output end of the motor B is rotationally connected with a threaded rod. Two sets of welding rings are threadedly connected to the outside of the threaded rod.

[0013] Preferably, the slider is fixedly connected to one end of the two sets of welding rings. One end of the slider away from the connection is fixedly connected with a push rod. One end of the push rod away from the slider is connected with an air inlet pipe, and the air inlet pipe is fixedly connected with the inside of the base.

[0014] Preferably, one end of the air inlet pipe away from the push rod is fixedly connected with a connecting pipe B, and the other end of the connecting pipe B penetrates through the limiting ring and is connected with an airbag.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. When the motor A drives the reciprocating lead screw to rotate, it will drive the pulley A to rotate synchronously. When the pulley A rotates, it will drive the pulley B to rotate synchronously through the belt. Since the grinding roller is connected to the pulley B, when the pulley B rotates, it will drive the grinding roller to rotate synchronously to grind the outer wall of the welded joint of the stainless steel pipe, so that the outer wall of the stainless steel pipe is smooth and flat, improving the welding efficiency after the subsequent butt joint of the stainless steel pipe. After the stainless steel pipe is ground, the stainless steel pipe will gradually move as the first support moves. At the same time, after the air enters the inside of the nozzle, it will be released upward, so as to clean the outer wall of the ground stainless steel pipe, preventing the residual grinding residues on the outer wall from affecting the welding effect;

[0017] At the same time, after the welding is completed, when the stainless steel pipe is taken out to one end, the nozzle will simultaneously cool the welded place, thereby improving the strength, toughness and corrosion resistance of the welded pipe. At the same time, after cooling, the grinding roller will also grind the welded joint, making the welded joint smoother and reducing the stress generated by welding, thus extending the service life of the stainless steel pipe weld in the future.

[0018] 2. When the stainless steel pipe enters the inside of the detection ring before welding, the movable rod will contact the outer wall of the stainless steel pipe. As the stainless steel pipe rotates, if the surface of the stainless steel pipe is offset, it will cause the movable rod to jump through the force of the spring. Therefore, before welding, the operator can judge whether the stainless steel pipe has defects through the jumping amplitude of the movable rod, preventing it from affecting the subsequent use effect after welding. At the same time, an uneven surface is prone to accumulate impurities, increasing the risk of pores and slag inclusions and weakening the weld strength.

[0019] 3. When the threaded rod rotates, it will drive the two welding rings on both sides to gradually move closer to the center, thus wrapping the stainless steel pipe. After the welding rings wrap the stainless steel pipe, welding is carried out. When the two welding rings move, they will drive the two sliders to move synchronously. When the sliders move, they will push the push rod into the inside of the air inlet pipe, squeezing the air inside the air inlet pipe into the rear end. The connecting pipe B will transport the air to the inside of the airbag through the connecting pipe B, so that the airbag expands to isolate the external air, preventing pores from forming in the weld during welding. The existence of pores will reduce the effective load-bearing area of the weld, reduce the strength and toughness of the weld, and may also become a crack source, causing crack propagation under stress, seriously affecting the service life and safety of the stainless steel pipe.

Detailed implementation manners

[0028] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-7 , a stainless steel welded pipe on-line bright solution annealing equipment, including a base 1, one end of the base 1 is fixedly connected with a motor A 2, the output end of the motor A 2 is connected with a reciprocating lead screw 3, the outside of the reciprocating lead screw 3 is provided with a first support 4, the inside of the first support 4 is connected with a movable ring 5, one side of the movable ring 5 is provided with a bevel gear 7, one side of the bevel gear 7 is provided with a gear A 10, the outside of the gear A 10 is connected with a rack A 11, one side of the first support 4 is fixedly connected with a second support 20, one side of the second support 20 is provided with a spray head 15, the inside of the second support 20 is provided with a grinding roller 19, one side of the spray head 15 is provided with a detection ring 21, one side of the detection ring 21 is provided with a limiting ring 24, and an airbag 25 is fixedly connected inside the limiting ring 24. A threaded rod 28 is arranged inside the base 1, a slider 29 is arranged on the outside of the threaded rod 28, one end of the slider 29 is fixedly connected with a push rod 30, and an air inlet pipe 31 is arranged at one end of the push rod 30.

[0030] In an alternative embodiment: Two sets of motor A2 are provided at both ends of the base 1. An empty slot is formed at the upper end of the base 1, and the reciprocating lead screw 3 is located inside the empty slot. The first support 4 is connected to the ball nut pair of the reciprocating lead screw 3 inside the empty slot. When the device is in use, the motor A2 drives the reciprocating lead screw 3 to rotate, so that when the reciprocating lead screw 3 rotates, it will drive the first support 4 to move synchronously.

[0031] In an alternative embodiment: The movable ring 5 is movably connected inside the first support 4. A toothed ring 6 is fixedly connected to the outer side of the movable ring 5. The toothed ring 6 meshes with the bevel gear 7. One end of the bevel gear 7 is fixedly connected with a connecting shaft 8. The end of the connecting shaft 8 away from the bevel gear 7 is fixedly connected with a gear A10. When the movable ring 5 rotates through the bevel gear 7, it drives the toothed ring 6 to rotate, so as to rotate. At the same time, when the gear A10 rotates, it will drive the connecting shaft 8 to rotate, so as to drive the bevel gear 7 to rotate synchronously. The inside of the movable ring 5 is made of a highly wear-resistant material, and the friction between it and the steel pipe is relatively large. Therefore, when two stainless steel pipes are placed inside the movable rings 5 at both ends during use, the stainless steel pipes will rotate synchronously through the rotation of the movable ring 5.

[0032] In an alternative embodiment: One end of the gear A10 is movably connected with a fixed rod 9. The connecting shaft 8 passes through the gear A10, and the gear A10 is fixedly connected to the first support 4 through the fixed rod 9 for fixation. The rack A11 is meshed and connected to the outside of the gear A10, and the rack A11 is fixedly connected to the base 1. When the first support 4 moves, it will drive the gear A10 to move synchronously through the fixed rod 9. Since the gear A10 and the fixed rod 9 are movably connected, when the gear A10 moves and contacts the rack A11, it will rotate through the rack A11.

[0033] In an alternative embodiment: The first support 4 is fixedly connected with a rack B12 on the opposite side of the fixed rod 9. The upper end of the base 1 is fixedly connected with a connecting pipe A14. The outside of the connecting pipe A14 is provided with the rack B12. One end of the rack B12 close to the connecting pipe A14 is fixedly connected with a connecting rod. The connecting rod passes through the connecting pipe A14 and extends to the inside to be connected with a valve. One end of the connecting pipe A14 is fixedly connected with a nozzle 15, and the other end is connected with a blower. While the first support 4 moves, it will drive the rack B12 to move synchronously. When the rack B12 moves, it will drive the gear B13 to rotate, so as to open the valve inside the connecting pipe A14, and make air enter the nozzle 15 through the connecting pipe A14.

[0034] In an alternative embodiment: One end of the reciprocating lead screw 3 away from the motor A2 is fixedly connected to a pulley A16. A belt 17 is sleeved inside the pulley A16. One end of the belt 17 away from the pulley A16 is sleeved with a pulley B18. One end of the pulley B18 close to the second support 20 is fixedly connected to a grinding roller 19. The grinding roller 19 is located inside the second support 20. When the motor A2 drives the reciprocating lead screw 3 to rotate, it will drive the pulley A16 to rotate synchronously. When the pulley A16 rotates, it will drive the pulley B18 to rotate synchronously through the belt 17. Since the grinding roller 19 is connected to the pulley B18, when the pulley B18 rotates, it will drive the grinding roller 19 to rotate synchronously to grind the outer wall of the welded joint of the stainless steel pipe, so that the outer wall of the stainless steel pipe is smooth and flat, improving the efficiency of subsequent welding after the docking of the stainless steel pipes. After the stainless steel pipe is ground, the stainless steel pipe will gradually move as the first support 4 moves. At the same time, as described above, after the air enters the inside of the nozzle 15, it will be released upward, so as to clean the outer wall of the ground stainless steel pipe, thus preventing the residual grinding residues on the outer wall from affecting the welding effect;

[0035] At the same time, after the welding is completed, when the stainless steel pipe is taken out to one end, the nozzle 15 will simultaneously cool the welded place, thereby improving the strength, toughness and corrosion resistance of the welded pipe. At the same time, after cooling, the grinding roller 19 will also grind the welded joint, so that the welded joint is more flat, and also reduces the stress generated by welding, thereby extending the service life of the subsequent use of the stainless steel pipe weld.

[0036] In an alternative embodiment: The detection ring 21 is fixed by connecting with the base 1. A plurality of groups of springs 23 are fixedly connected to the outside of the detection ring 21. One end of each of the plurality of groups of springs 23 is fixedly connected to a movable rod 22. The movable rod 22 penetrates through the detection ring 21 and extends to the inside. When the stainless steel pipe enters the inside of the detection ring 21 before welding, the movable rod 22 will contact the outer wall of the stainless steel pipe. Thus, as the stainless steel pipe rotates, if the surface of the stainless steel pipe is deflected, it will cause the movable rod 22 to jump through the force of the spring 23. Therefore, before welding, the staff can judge whether the stainless steel pipe has defects through the jumping amplitude of the movable rod 22, preventing it from affecting the subsequent use effect after welding. At the same time, an uneven surface is prone to accumulate impurities, increasing the risk of pores and slag inclusions and weakening the weld strength.

[0037] In an alternative embodiment: The limit ring 24 is fixedly connected to the base 1. One side of the base 1 is fixedly connected with a motor B27. The output end of the motor B27 is rotationally connected to a threaded rod 28. The outer side of the threaded rod 28 is threadedly connected with a welding ring 26. The number of the welding rings 26 is two groups. When the two stainless steel pipes move to the center and contact each other, at this time, the motor B27 is started. When the motor B27 is started, it will drive the threaded rod 28 to rotate synchronously. At this time, the movable rings 5 at both ends will apply a certain extrusion force to the two stainless steel pipes, so that the two stainless steel pipes are more closely attached to each other, thereby improving the welding efficiency.

[0038] In an alternative embodiment: The slider 29 is fixedly connected to one end of the two welding rings 26. One end of the slider 29 away from the connection is fixedly connected with a push rod 30. One end of the push rod 30 away from the slider 29 is connected with an air inlet pipe 31. The air inlet pipe 31 is fixedly connected to the inside of the base 1. When the threaded rod 28 rotates, it will drive the two welding rings 26 on both sides to gradually move closer to the center, so as to wrap the stainless steel pipe. After the welding ring 26 wraps the stainless steel pipe, welding is carried out. When the two welding rings 26 move, they will drive the two sliders 29 to move synchronously. When the slider 29 moves, it will push the push rod 30 into the air inlet pipe 31, so as to squeeze the air inside the air inlet pipe 31 into the rear end.

[0039] In an alternative embodiment: One end of the air inlet pipe 31 away from the push rod 30 is fixedly connected with a connecting pipe B32. The other end of the connecting pipe B32 penetrates through the limit ring 24 and is connected with the airbag 25. As described above, the connecting pipe B32 will convey air to the inside of the airbag 25 through the connecting pipe B32, so that the airbag 25 expands to isolate the external air, thereby preventing the formation of pores in the weld during welding. The existence of pores will reduce the effective bearing area of the weld, reduce the strength and toughness of the weld, and may also become a crack source, causing crack propagation under stress, seriously affecting the service life and safety of the stainless steel pipe.

[0040] Working principle: When in use, the two stainless steel pipes are placed inside the movable rings 5 at both ends. At this time, the motor 2 is started. The motor A2 drives the reciprocating screw rod 3 to rotate. When the reciprocating screw rod 3 rotates, it will drive the first support 4 to move synchronously. When the first support 4 moves, it will drive the gear A10 to move synchronously through the fixed rod 9. Since the gear A10 is movably connected to the fixed rod 9, when the gear A10 moves and contacts the rack A11, it will rotate through the rack A11. At the same time, when the gear A10 rotates, it will drive the connecting shaft 8 to rotate, thereby driving the bevel gear 7 to rotate synchronously. And the inside of the movable ring 5 uses a highly wear-resistant material, and the friction force with the steel pipe is relatively large. Therefore, the stainless steel pipe will rotate synchronously through the rotation of the movable ring 5;

[0041] When the first support 4 moves, it will drive the rack B12 to move synchronously. When the rack B12 moves, it will drive the gear B13 to rotate, thereby opening the valve inside the connecting pipe A14, allowing air to enter the nozzle 15 through the connecting pipe A14. When the motor A2 drives the reciprocating screw 3 to rotate, it will drive the pulley A16 to rotate synchronously. When the pulley A16 rotates, it will drive the pulley B18 to rotate synchronously through the belt 17. Because the grinding roller 19 is connected to the pulley B18, when the pulley B18 rotates, it will drive the grinding roller 19 to rotate synchronously to grind the outer wall of the stainless steel pipe welding part, so that the outer wall of the stainless steel pipe is smooth and flat, thereby improving the efficiency of subsequent welding after the stainless steel pipe is butt-jointed. After the stainless steel pipe is polished, the stainless steel pipe will gradually move with the movement of the first support 4. At the same time, after the air enters the nozzle 15, it will be released upward, thereby cleaning the polished outer wall of the stainless steel pipe, thereby preventing the grinding residues remaining on the outer wall from affecting the welding effect;

[0042] At the same time, after the welding is completed, when the stainless steel pipe is taken out at one end, the nozzle 15 will cool down the welded area at the same time, thereby improving the strength, toughness and corrosion resistance of the welded pipe. At the same time, after cooling down, the grinding roller 19 will also grind the welded area, thereby making the welded area smoother and reducing the stress generated by welding, thereby extending the subsequent service life of the stainless steel pipe weld;

[0043] When the stainless steel pipe enters the detection ring 21 before welding, the movable rod 22 will contact the outer wall of the stainless steel pipe. As the stainless steel pipe rotates, if the surface of the stainless steel pipe deviates, the movable rod 22 will jump due to the force of the spring 23. Therefore, the staff can judge whether the stainless steel pipe has defects by the jumping amplitude of the movable rod 22 before welding, so as to prevent the subsequent use effect from being affected after welding. At the same time, impurities are easily accumulated on the uneven surface, which increases the risk of pores and slag inclusions and weakens the strength of the weld.

[0044] When the two groups of stainless steel pipes move to the center and come into contact, the motor B27 is started at this time. When the motor B27 starts, it will drive the threaded rod 28 to rotate synchronously. At this time, the movable rings 5 at both ends will apply a certain extrusion force to the two groups of stainless steel pipes, so that the two groups of stainless steel pipes fit more closely. When the threaded rod 28 rotates, it will drive the welding rings 26 on both sides to gradually move closer to the center, so as to wrap the stainless steel pipes. After the welding rings 26 wrap the stainless steel pipes, welding is carried out. When the two welding rings 26 move, they will drive the two sliders 29 to move synchronously. When the sliders 29 move, they will push the push rod 30 into the air inlet pipe 31, so as to squeeze the air inside the air inlet pipe 31 into the rear end. The connecting pipe B32 will transport the air through the connecting pipe B32 into the airbag 25, so that the airbag 25 expands to isolate the external air, so as to prevent pores from forming in the weld during welding. The existence of pores will reduce the effective bearing area of the weld, reduce the strength and toughness of the weld, and may also become a crack source, causing crack propagation under stress, seriously affecting the service life and safety of the stainless steel pipe.

[0045] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
