Description

Technical Field

[0001] This invention relates to the field of metal welding technology, specifically a metal pipe welding apparatus. Background Technology

[0002] Metal welding technology is a forming method that uses heating, pressurization, or both to create interatomic bonding forces between two separate metal objects, thus joining them into one piece. This technology is widely used in many fields such as machinery manufacturing, shipbuilding, marine development, automobile manufacturing, petrochemicals, aerospace technology, power, electronics, and construction.

[0003] A Chinese patent with publication number CN117644392A discloses a metal pipe welding device, including an L-shaped connecting frame, a vertical fixing plate, a transmission rod one, a transmission rod two, a chuck one, a chuck two, a square groove, a square block, and a processing unit. This invention, through the structural design of the transmission rod one, transmission rod two, chuck one, chuck two, and welding head, aims to achieve rotary welding at pipe gaps, improving welding quality and reducing manual adjustment workload. The processing unit, composed of impeller blades, a circular shell, an air blowing pipe, and an air outlet pipe, is linked to the transmission rod two in clockwise or counterclockwise motion. This allows for temperature control of the grinding area. By continuously cooling and intermittently blowing air, a suitable temperature is ensured during grinding, thereby improving the accuracy and consistency of grinding. This design helps to make the weld joint smoother and more even, improving welding strength and sealing performance, meeting engineering needs and usage requirements.

[0004] As mentioned above, the patent provides a metal pipe welding device that uses continuous cooling and intermittent blowing to assist in post-weld grinding, improving the welding strength and sealing performance. However, during welding, the welding surface needs to be constantly adjusted, and welding must be stopped before this adjustment process. Welding can only resume after adjustment, making it impossible to guarantee a perfect rejoining of the weld before stopping. This results in the need for multiple welding operations to ensure that there is no seal after welding. Multiple welding operations can lead to significant unevenness on the pipe surface and are prone to burn-through or over-welding. Therefore, a metal pipe welding device is proposed to address the above problems. Summary of the Invention

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figure 1 - Figure 10 As shown, a metal pipe welding device includes a working box 1, a fixing component, an adjusting component, and a rotating component; the fixing component includes a retaining ring 2, the adjusting component includes a sliding retaining cylinder 3 and a T-shaped retaining block 4, and the rotating component includes a sliding retaining shaft 5.

[0035] The surface of the sliding shaft 5 is slidably connected to the top of the working housing 1. One end of the sliding shaft 5 passes through the working housing 1 and extends into the interior of the working housing 1. A square locking block 6 is fixedly connected to the end of the sliding shaft 5 inside the working housing 1. A sliding cavity 7 is opened inside the square locking block 6. An arc-shaped locking block 8 is slidably connected to the inner wall of the sliding cavity 7. A support locking rod 9 is fixedly connected to one side of the inner wall of the sliding cavity 7. One end of the support locking rod 9 passes through the arc-shaped locking block 8 and extends into the interior of the arc-shaped locking block 8. A compression spring 10 is sleeved on the surface of the support locking rod 9. The two ends of the compression spring 10 are fixedly connected to one side of the arc-shaped locking block 8 and one side of the inner wall of the sliding cavity 7, respectively. A tension spring 11 is fitted on the surface of the sliding shaft 5. A lifting plate 12 is fixedly connected to the top of the sliding shaft 5. The two ends of the tension spring 11 are fixedly connected to the bottom of the lifting plate 12 and the top of the working box 1, respectively. A motor base 13 is fixedly connected to the top of the working box 1. A motor 14 is fixedly connected to the top of the motor base 13. A rotating boss 15 is fixedly connected to the output shaft of the motor 14 through a coupling. A rotating bracket 16 is fixedly connected to one side of the inner wall of the working box 1. The inner side of the rotating bracket 16 is rotatably connected to the surface where the retaining ring 2 is placed. A windmill-shaped retaining plate 17 that is adapted to the arc-shaped retaining block 8 is fixedly connected to the surface of the retaining ring 2 away from the rotating bracket 16.

[0036] During operation, the interior of the work chamber 1 is used for welding metal pipe fittings. Two pipes to be welded are inserted through both sides of the work chamber 1, and the metal pipe fittings are supported by the sliding clamp 3. Then, the welding joint of the pipes is fixed using a fixing assembly. The motor base 13 is fixed to the top of the work chamber 1 to support the motor 14. To achieve the rotating welding function, the motor 14 on the top of the motor base 13 rotates, driving the rotating boss 15 to rotate. When the rotating boss 15 rotates to contact the bottom of the lifting clamp 12, it lifts the lifting clamp 12, thereby driving the sliding clamp shaft 5 to rise and fall. The lifting mechanism causes the square locking block 6 to rise and fall, which in turn causes the arc-shaped locking block 8 to rise and fall. When the arc-shaped locking block 8 abuts against the surface of the windmill-shaped locking plate 17, the arc-shaped surface of the windmill-shaped locking plate 17 causes the arc-shaped locking block 8 to slide inside the sliding cavity 7, thereby locking the arc-shaped locking block 8 into the sliding cavity 7 inside the square locking block 6. After the arc-shaped locking block 8 is completely disengaged from the arc-shaped surface of the windmill-shaped locking plate 17, the compression spring 10 inside the sliding cavity 7 generates internal tension due to compression, pushing the arc-shaped locking block 8 outward along the support rod 9, thus restoring it to the state of being locked on the outside of the square locking block 6. At this time, the rotating boss 15 begins to gradually disengage from the lifting locking plate 12, and the sliding locking... The tension spring 11 on the surface of shaft 5 is in a stretched state. After stretching, it generates tension, pulling down the lifting plate 12 and the sliding shaft 5. The sliding shaft 5 then drives the square block 6 to move downward. At this time, the bottom of the arc-shaped block 8 abuts against the horizontal surface of the windmill-shaped plate 17, thereby causing the windmill-shaped plate 17 to start rotating. The rotation of the windmill-shaped plate 17 causes the placement ring 2 fixed to it to start rotating. At the same time, the rotating bracket 16 is fixed on the inner wall of the working box 1 to support the placement ring 2. The fixing component is set on the placement ring 2, that is, the pipe to be welded is fixed on the placement ring 2, thereby realizing the function of the placement ring 2 rotating to drive the pipe to rotate. The rotating boss 15 is used to achieve periodic rotation, which drives the metal pipe to rotate after welding. The whole can rotate at a periodic angle and welding can be carried out at the same time, ensuring the continuity of the welding process. It eliminates the need for repeated welding and solves the problem of having to stop welding before adjustment and then continue welding after adjustment. This prevents the weld from being perfectly connected to the previous weld and requires multiple welding to ensure that there is no seal after welding. Multiple welding will result in a large unevenness on the pipe surface and is prone to weld burn-through or over-welding. This improves the efficiency of welding.

[0037] Furthermore, the number of support rods 9 is set to three, and the three support rods 9 are evenly arranged at equal intervals on the inner wall of the sliding cavity 7. The number of sliding shafts 5 is set to two, and the two sliding shafts 5 are symmetrically arranged on both sides of the bottom of the lifting plate 12. The surface of the placement ring 2 is threadedly connected to an adjusting screw 18. One end of the adjusting screw 18 passes through the placement ring 2 and extends into the interior of the placement ring 2. The end of the adjusting screw 18 located inside the placement ring 2 is rotatably connected to a pressing block 19. The surface of the pressing block 19 is fixedly connected to a limiting rod 20. The surface of the limiting rod 20 is slidably connected to the surface of the placement ring 2. The number of pressing blocks 19 is set to four, and the four pressing blocks 19 are evenly arranged on the circumference of the surface of the placement ring 2.

[0038] During operation, three support rods 9 are evenly spaced on the inner wall of the sliding cavity 7 to ensure effective support for the arc-shaped clamping block 8. Two sliding shafts 5 are also provided, each capable of rotating one of the two welded pipes simultaneously. An adjusting screw 18 is threaded onto the surface of the clamping ring 2. Rotation of the adjusting screw 18 causes the pressing clamping block 19 to extend and retract within the clamping ring 2, thus clamping onto the pipe surface. When all four pressing clamping blocks 19 are fully clamped onto the pipe surface, the pipe is secured. Furthermore, a limiting rod 20 is fixed to the surface of the pressing clamping block 19 to limit its movement, preventing the adjusting screw 18 from rotating and causing lateral deviation. This ensures the arc-shaped surface of the pressing clamping block 19 is perfectly clamped onto the pipe, improving the adaptability of the fixation. This achieves the function of fixing the position of the weld joint of the two welded pipes and, in conjunction with rotation, ensures stability during rotational welding, solving the problem of instability in rotational welding and improving overall welding stability.

[0039] Furthermore, the surface of the sliding cylinder 3 is slidably connected to one side of the working box 1. Both ends of the sliding cylinder 3 are fixedly connected to a connecting ring 21. Both ends of the sliding cylinder 3 are fixedly connected to a limit support rod 22 through the connecting ring 21. The surface of the limit support rod 22 is slidably connected to the surface of the working box 1. The surface of the connecting ring 21 is threadedly connected to a positioning screw 23. One end of the positioning screw 23 is rotatably connected to the surface of the working box 1. The number of sliding cylinders 3 is set to two, and the two sliding cylinders 3 are symmetrically arranged on both sides of the working box 1. A spring telescopic rod 24 is fixedly connected to one side of the inner wall of the sliding cylinder 3. A limit arc block 25 is fixedly connected to the end of the spring telescopic rod 24 away from the inner wall of the sliding cylinder 3. The number of spring telescopic rods 24 and limit arc blocks 25 is set to four, and the four spring telescopic rods 24 and limit arc blocks 25 are evenly arranged on the circumference of the inner wall of the sliding cylinder 3.

[0040] During operation, the sliding clamp 3 can slide on both sides of the working box 1. The connecting ring 21 is fixed at both ends of the sliding clamp 3, and a limiting support rod 22 is fixed on the surface of the connecting ring 21. The limiting support rod 22 is slidably connected to the surface of the working box 1, thereby supporting and limiting the sliding clamp 3. Inside the sliding clamp 3, a spring telescopic rod 24 is fixed, and a limiting arc block 25 is fixed at one end of the spring telescopic rod 24. When the pipe is inserted into the sliding clamp 3, the elastic extension and contraction of the spring telescopic rod 24 drives the limiting arc block 25 to extend and contract, thereby clamping it on the surface of the pipe and supporting the pipe. When the pipe length is small and needs to be adjusted, the positioning screw 23 is rotated to drive the connecting ring 21 to move, thereby pushing the sliding clamp 3 closer to the inside of the working box 1, thereby continuously moving the spring telescopic rod 24 and the limiting arc block 25 into the working box 1, so that it can accommodate shorter metal pipes and support the pipes.

[0041] Furthermore, a placement block 26 is fixedly connected to the top of the T-shaped block 4, and an adjusting sleeve 27 is rotatably connected to the top of the placement block 26. A lifting screw 28 is threadedly connected to the inside of the adjusting sleeve 27, and an arc-shaped placement platform 29 is fixedly connected to the top of the lifting screw 28. Spring telescopic support rods 30 are fixedly connected to both sides of the top of the arc-shaped placement platform 29. The bottom end of the spring telescopic support rod 30 is fixedly connected to the top of the placement block 26. A T-shaped slide rail 31 adapted to the T-shaped block 4 is provided at the bottom of the inner wall of the working box 1. The number of T-shaped blocks 4 and arc-shaped placement platforms 29 is set to two, and the two T-shaped blocks 4 and arc-shaped placement platforms 29 are symmetrically arranged on both sides of the T-shaped slide rail 31. A two-way screw rod 32 is threadedly connected to the surface of the two T-shaped blocks 4. One end of the two-way screw rod 32 passes through the working box 1 and extends to one side of the working box 1. An adjusting turntable 33 is fixedly connected to the end of the two-way screw rod 32 located on one side of the working box 1.

[0042] During operation, the T-shaped clamping block 4 has a fixed placement block 26 on top. The adjusting sleeve 27 can rotate on top of the placement block 26. After the adjusting sleeve 27 rotates, it drives the lifting screw 28 to rise and fall, which in turn drives the arc-shaped placement clamping platform 29 to rise and fall, thereby adjusting the height of the arc-shaped placement clamping platform 29. It can support pipes of different diameters. In addition, spring telescopic support rods 30 are fixed on both sides of the bottom of the arc-shaped placement clamping platform 29. The spring telescopic support rods 30 can rise and fall with the arc-shaped placement clamping platform 29. At the same time, the spring telescopic support rods 30 can prevent the lifting screw 28 from rotating when the adjusting sleeve 27 rotates, ensuring that the arc-shaped placement clamping platform 29 can rise and fall normally. In addition, a T-shaped slide rail 31 is opened at the bottom of the inner wall of the working box 1 for placing... The T-shaped locking block 4 is used to limit its position. A two-way screw rod 32 is threaded onto the surface of the T-shaped locking block 4. The two-way screw rod 32 passes through the working box 1, and an adjusting turntable 33 is fixed at one end of the working box 1. The rotation of the adjusting turntable 33 drives the two-way screw rod 32 to rotate, which in turn causes the T-shaped locking block 4 to move away from or closer to each other inside the T-shaped slide rail 31, thereby adjusting the position of the T-shaped locking block 4. This, together with the sliding clamp 3, supports the pipeline. The adjustment of the T-shaped locking block 4 and the sliding of the sliding clamp 3 inside the working box 1 realize the function of adjusting the support position of the pipeline. This solves the problem of poor adaptability of welding support due to the different lengths and diameters of the pipelines to be welded, and improves the adaptability to metal pipe fittings of different specifications and sizes.

[0043] Furthermore, a strip groove 34 is provided on one side of the working box 1. A lifting platform 35 is slidably connected to the inner wall of the strip groove 34. A sliding bracket 36 is fixedly connected to the surface of the lifting platform 35. The surface of the sliding bracket 36 is slidably connected to the surface of the working box 1. An electric telescopic rod 37 is fixedly connected to the surface of the sliding bracket 36. One end of the electric telescopic rod 37 passes through the lifting platform 35 and extends to one side of the lifting platform 35. A welder 38 is fixedly connected to one end of the electric telescopic rod 37 located on one side of the lifting platform 35. A hydraulic rod 39 is fixedly connected to the top of the working box 1. One end of the hydraulic rod 39 passes through the working box 1 and extends into the interior of the strip groove 34. The end of the hydraulic rod 39 located inside the strip groove 34 is fixedly connected to the surface of the lifting platform 35.

[0044] During operation, a strip-shaped chute 34 is formed inside the work box 1 to house the lifting platform 35, allowing the platform to slide up and down within the chute. During this sliding motion, a hydraulic rod 39 drives the platform 35 to rise and fall. A sliding bracket 36 is fixed to the surface of the platform 35, allowing it to move up and down as well. An electric telescopic rod 37 is fixed to the surface of the sliding bracket 36, with one end passing through the platform 35. The electric telescopic rod 37 drives the welder 38 to move horizontally. This, combined with the lifting of the platform 35, allows for horizontal and vertical adjustment of the welder 38. This adjustment is suitable for pipes of different diameters, ensuring the welder 38 can smoothly contact the pipe surface for welding, thus improving adaptability to metal pipes of different sizes.

[0045] Furthermore, a support base 40 is fixedly connected to the bottom of the working box 1, a support leg 41 is fixedly connected to the bottom of the support base 40, and a protective box door 42 is hinged to the surface of the working box 1.

[0046] During operation, the support base 40 is fixed to the bottom of the working box 1 to support the working box 1. The bottom of the support base 40 is fixed with support legs 41, which support the support base 40. Finally, a protective door 42 is hinged to the surface of the working box 1 to protect the inside of the working box 1.

[0047] Example 2: Please refer to Figure 2 - Figure 4 As shown in the comparative embodiment 1, which is another implementation of the present invention, a sliding rail 43 is provided on one side of the working box 1. An exhaust ventilation plate 44 is slidably connected to the inner wall of the sliding rail 43. During operation, exhaust ventilation plate 44 can be used to exhaust and ventilate during welding, which can prevent welding odors from accumulating inside and causing the odor to be released all at once when the protective box door 42 is opened, thus avoiding discomfort to the staff.
