Description
Technical Field
[0001] This invention belongs to the field of spiral steel pipe production and welding technology, specifically relating to an automatic welding equipment for spiral steel pipe structure production. Background Technology
[0002] The core of spiral welded steel pipe production is the main line of strip steel coil, spiral forming and double-sided submerged arc welding. Welding equipment is the most critical and complex part of the entire production line. Almost the entire industry uses submerged arc welding for spiral welded steel pipe welding because the weld is long, the pipe wall is thick, and high strength and sealing are required.
[0003] In existing technology, when performing internal welding on steel coils, the equipment sprays submerged arc welding flux onto the weld seam of the steel coil while simultaneously welding with a welding torch. Submerged arc welding flux has the effects of covering the electric arc, isolating air, slag formation and deoxidation, and stabilizing the electric arc. However, during the welding process, the submerged arc welding flux is directly exposed to the outside and is easily blown away by the wind, affecting the welding effect of the steel coil. At the same time, excess submerged arc welding flux on the steel coil will move with the steel coil, resulting in the inside of the finished steel pipe being full of submerged arc welding flux, which is inconvenient for workers to collect.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0032] Reference Figure 1 - Figure 12An automatic welding device for producing spiral steel pipe structures is provided, comprising a welding mechanism, an adjustment mechanism, and an auxiliary mechanism. During welding of the steel pipe, the device can gather the submerged arc welding flux at the weld seam to prevent it from being blown away by the wind and affecting the welding effect. The device can adjust the discharge rate of the submerged arc welding flux according to actual work needs to avoid waste. During the welding process, the device can collect the submerged arc welding flux on the inner wall of the steel pipe for subsequent use, preventing the flux from scattering inside the steel pipe.
[0033] Furthermore, the welding mechanism can complete the welding of steel pipes. When welding steel pipes, it can prevent the submerged arc welding flux from being blown away by the wind. It includes a support frame 10, with multiple support wheels 11 at the bottom of the support frame 10. The multiple support wheels 11 are evenly distributed on the support frame 10. The top of the support frame 10 is provided with a storage box 12 for placing the submerged arc welding flux. The support frame 10 is provided with a welding gun 13. The support frame 10 is provided with a discharge part 14 and a lifting part 15. The lifting part 15 is provided with a blocking part 16.
[0034] In use, the support wheel 11 is located on the steel coil. As the steel coil moves, the support wheel 11 rolls. The welding gun 13 welds the steel coil. The welding of the steel coil is existing technology and will not be described in detail here.
[0035] Furthermore, the discharge section 14 includes a second through-hole 141 disposed on the support frame 10. The discharge pipe 142 is disposed inside the second through-hole 141. One end of the discharge pipe 142 is connected to the storage box 12, and the other end of the discharge pipe 142 faces the ground.
[0036] During use, the submerged arc welding flux inside the storage box 12 falls through the discharge pipe 142 to the joint between the steel coils. The function of the submerged arc welding flux is to cover the electric arc, isolate the air, form slag and deoxidize, and stabilize the electric arc.
[0037] Furthermore, the lifting unit 15 includes a storage slot 151 and a third through-hole 152 disposed on the support frame 10. The storage slot 151 and the third through-hole 152 are interconnected. There are two storage slots 151, and each of the two storage slots 151 is provided with a lifting plate 153 inside.
[0038] It should be noted that in the initial state, the lifting plate 153 is located at the bottom of the storage slot 151. The lifting plate 153 can be raised and lowered inside the storage slot 151, and the lifting plate 153 cannot be detached from the inside of the storage slot 151.
[0039] Furthermore, the blocking part 16 includes a first slider 161 disposed at the bottom of the lifting plate 153, the top of the first slider 161 being slidably connected to the bottom of the lifting plate 153, and a first baffle 162 being disposed on the first slider 161.
[0040] It should be noted that there are two lifting plates 153, and each of the two lifting plates 153 has a first slider 161 at its bottom, and there are two first baffles 162.
[0041] During use, as the bottom of the first baffle 162 contacts the steel coil, the first baffle 162 will rise. The first baffle 162 will drive the slider to rise together, and the slider will drive the lifting plate 153 to rise inside the storage groove 151. The bottom of the first baffle 162 is in constant contact with the steel coil. By setting two first baffles 162, the submerged arc welding flux discharged from the discharge pipe 142 is gathered together to prevent the submerged arc welding flux from scattering in all directions during the falling process.
[0042] Furthermore, the adjustment mechanism can adjust the amount of submerged arc welding flux at the weld as needed. It includes a first through-hole 20 set on the support frame 10, a threaded rod 21 set inside the first through-hole 20, the top end of the threaded rod 21 extending to the top of the support frame 10, the bottom end of the threaded rod 21 extending to the bottom of the support frame 10, a dial ring 22 set on the side wall of the threaded rod 21, the dial ring 22 being located at the top of the support frame 10, a follower part 23 connected to the bottom of the threaded rod 21, an adjustment part 24 set on the follower part 23, and a switch part 25 for controlling the amount of submerged arc welding flux discharged on the discharge part 14.
[0043] It should be noted that the dial ring 22 can rotate on the top of the support frame 10, and when the dial ring 22 rotates, it can control the threaded rod 21 to rise and fall.
[0044] Furthermore, the follower 23 includes a fixing frame 231 disposed at the bottom of the threaded rod 21, the side wall of the fixing frame 231 is in contact with the side wall of the lifting plate 153, and a pressing block 232 is disposed on the fixing frame 231.
[0045] It should be noted that the fixed frame 231 is located between the two lifting plates 153. The position of the fixed frame 231 is restricted by the setting of the two lifting plates 153, so as to prevent the fixed frame 231 from rotating and make the fixed frame 231 only able to move up and down.
[0046] When in use, when the dial ring 22 rotates, the threaded rod 21 drives the fixed frame 231 to rise, and when the fixed frame 231 rises, it drives the pressing block 232 to rise together.
[0047] Furthermore, the adjustment part 24 includes a first inclined surface 241 disposed on the extrusion block 232, a second inclined surface 242 disposed on the first slider 161, and a spring 243 disposed on the side wall of the first baffle 162.
[0048] It should be noted that there are multiple springs 243, which are evenly distributed between the two first baffles 162, and the first inclined surface 241 and the second inclined surface 242 are parallel to each other.
[0049] When in use, when the pressing block 232 rises, the pressing block 232 drives the first inclined surface 241 to press the second inclined surface 242, causing the two first baffles 162 to move away from each other, causing the spring 243 to extend. When the pressing block 232 falls, the spring 243 returns to its original position, causing the two first baffles 162 to return to their initial position.
[0050] Furthermore, the switch unit 25 includes a fixed sleeve 251 disposed on the side wall of the discharge pipe 142, a groove 252 is provided on the first baffle 162, a second slider 253 is disposed inside the groove 252, one end of the second slider 253 is connected to a second baffle 254, the second baffle 254 is located inside the fixed sleeve 251, and the top of the second baffle 254 contacts the end of the discharge pipe 142. The discharge amount of submerged arc welding flux inside the discharge pipe 142 is controlled according to the change of the distance between the two second baffles 254.
[0051] In use, the second slider 253 is unaffected when the first baffle 162 is raised or lowered due to the setting of the slide groove 252. When the two first baffles 162 move away from each other, the first baffle 162 drives the second slider 253, and the second slider 253 drives the second baffle 254 to move together, so that the two second baffles 254 move away from each other. The second baffles 254 move inside the fixed sleeve 251, thereby controlling the discharge amount of submerged arc welding flux inside the discharge pipe 142.
[0052] Furthermore, the auxiliary mechanism can collect excess submerged arc welding flux after welding for convenient subsequent use. It includes a pump body 30 mounted on the support frame 10, a material conveying pipe 31 and a material extraction pipe 32 mounted on the pump body 30, one end of the material extraction pipe 32 being adjacent to the first baffle 162, a rolling part 33 mounted on the adjusting part 24, a flipping part 34 mounted on the rolling part 33, and an extension part 35 mounted on the flipping part 34.
[0053] During use, when welding steel coils, the submerged arc welding flux moving out from between the two first baffles 162 can enter the interior of the storage box 12 through the extraction pipe 32 and the delivery pipe 31 under the action of the pump body 30, thus avoiding waste of submerged arc welding flux.
[0054] Furthermore, the rolling part 33 includes a first rotating shaft 331 and a second rotating shaft 332 disposed on the first slider 161. There are four first sliders 161, arranged in pairs. The first rotating shaft 331 is disposed on one slider and the second rotating shaft 332 is disposed on the other slider. One end of the first rotating shaft 331 is connected to a first roller 333, and one end of the second rotating shaft 332 is connected to a second roller 334. The first roller 333 and the second roller 334 are the same size.
[0055] It should be noted that both the first roller 333 and the second roller 334 are rubber wheels. When the first baffle 162 contacts the surface of the steel coil, the first roller 333 and the second roller 334 simultaneously contact the surface of the steel coil. As the steel coil moves, the first roller 333 and the second roller 334 can roll on the surface of the steel coil.
[0056] Furthermore, the flipping part 34 includes a first flipping plate 341 disposed on the side wall of the first rotating shaft 331, a first groove 342 disposed on the first flipping plate 341, a second flipping plate 343 disposed inside the first groove 342, and one end of the second flipping plate 343 connected to the side wall of the second rotating shaft 332.
[0057] It should be noted that the height of the material extraction tube 32 is equivalent to the height of the first rotating shaft 331 from the steel coil, and the width of the material extraction tube 32 is equivalent to the farthest distance between the two first sliders 161. There are multiple first flip plates 341 and multiple second flip plates 343. Multiple first flip plates 341 are evenly distributed on the side wall of the first rotating shaft 331, and multiple second flip plates 343 are evenly distributed on the side wall of the second rotating shaft 332. The end face of the first rotating shaft 331 is in contact with the end face of the second rotating shaft 332.
[0058] Furthermore, the extension 35 includes a second groove 351 and a slot 352 disposed at the end of the first rotating shaft 331. The second groove 351 and the slot 352 are interconnected. The other end of the second rotating shaft 332 is connected to a short rod 353. A locking block 354 is disposed on the side wall of the short rod 353. The short rod 353 is located inside the second groove 351, and the locking block 354 is located inside the slot 352.
[0059] In use, when the two first sliders 161 move away from each other, the first roller 333 and the second roller 334 move away from each other. During this process, the second roller 334 drives the second rotating shaft 332, which in turn drives the short rod 353 and the second flip plate 343 to move together. The second flip plate 343 moves outward from the inside of the first groove 342, and the short rod 353 drives the locking block 354 to move outward from the second groove 351. This ensures that the sum of the dimensions of the first flip plate 341 and the second flip plate 343 matches the distance between the two sliders at all times, guaranteeing that the submerged arc welding flux between the two first baffles 162 is fully covered, facilitating the subsequent collection of the submerged arc welding flux. Through the cooperation of the first flip plate 341 and the second flip plate 343, the extraction tube 32 and the submerged arc welding flux can be separated, preventing the extraction tube 32 from affecting the submerged arc welding flux between the two first baffles 162 when collecting the submerged arc welding flux outside the first baffle 162.
[0060] Working principle: When welding is required on the inner wall of the steel coil, the support frame 10 is placed in the designated position so that the welding torch 13 is aimed at the weld seam between the steel coils. The two first baffles 162 are located on both sides of the weld seam. As the steel coil moves, the support wheel 11, the first roller 333 and the second roller 334 roll simultaneously. The submerged arc welding flux inside the storage box 12 falls onto the weld seam through the discharge pipe 142. The setting of the two first baffles 162 achieves the effect of gathering the submerged arc welding flux and prevents the wind from blowing the submerged arc welding flux away.
[0061] When it is necessary to control the discharge amount of submerged arc welding flux from the discharge pipe 142, the operator can drive the dial ring 22. The dial ring 22 drives the threaded rod 21 to rise. During the rise of the threaded rod 21, the fixed frame 231 also rises. The fixed frame 231 drives the extrusion block 232 to rise. Through the setting of the first inclined surface 241 and the second inclined surface 242, as the extrusion block 232 gradually rises, the two first sliders 161 move away from each other. The two first sliders 161 drive the two first baffles 162 to move away from each other. The two first baffles 162 drive the spring 243 to extend, increasing the distance between the two first baffles 162, so that more submerged arc welding flux can be placed at the same position. At the same time, the two first baffles 162 drive the second slider 253 to move. The second slider 253 drives the second baffle 254 to move, so that the two second baffles 254 move away from each other, so that more submerged arc welding flux is discharged from the discharge pipe 142. At the same time, as the two first sliders 161 move away from each other, the first roller 33... 3. The first roller 333 and the second roller 334 move away from each other, causing the second flip plate 343 to gradually extend outward from the inside of the first groove 342. As the first roller 333 and the second roller 334 roll, the first roller 333 drives the first rotating shaft 331 to rotate. The first rotating shaft 331 drives the first flip plate 341 and the locking block 354 to rotate together. The locking block 354 drives the short rod 353 to rotate. The short rod 353 drives the second rotating shaft 332 to rotate. The second rotating shaft 332 drives the second roller 334 and the second flip plate 343 to rotate together. During the rotation of the first flip plate 341 and the second flip plate 343, the submerged arc welding flux on the steel coil can be separated in sequence, so as to avoid the pump body 30 affecting the submerged arc welding flux between the two first baffles 162 when pumping material. The submerged arc welding flux located outside the two first baffles 162 is sucked into the pump body 30 and then discharged into the storage box 12 through the conveying pipe 31. The submerged arc welding flux that enters the storage box 12 can fall back to the weld between the steel coils through the discharge pipe 142.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
