Description

Technical Field

[0001] This utility model relates to the field of flipping equipment technology, specifically a pipe welding flipping equipment. Background Technology

[0002] In fields such as pipeline engineering and pressure vessel manufacturing, pipe welding is one of the core processes. Its welding quality and work efficiency directly affect the progress and safety of the entire project. With the improvement of industrial automation, pipe welding equipment is gradually developing towards mechanization and intelligence. Among them, pipe turning equipment, as a key auxiliary welding device, drives the pipe to rotate so that the weld is in the best welding position, and has become an important guarantee for improving welding quality.

[0003] Existing pipe welding and turning equipment still has certain shortcomings in practical applications: On the one hand, the roller spacing and height of most equipment are fixed, which can only be adapted to pipes of a single or small diameter range. When different specifications of pipes need to be processed, the entire roller assembly needs to be replaced or the overall structure of the equipment needs to be adjusted, which is cumbersome and time-consuming, greatly reducing production flexibility and work efficiency. On the other hand, some equipment adopts manual assisted turning or a single active wheel drive. Manual turning is not only labor-intensive and prone to uneven turning, which leads to weld position displacement and affects welding quality, but a single active wheel drive is prone to concentrated stress on the pipe, especially for large-diameter thin-walled pipes, which can easily cause pipe deformation and further increase the risk of welding defects.

[0004] In view of this, we propose a pipe welding and turning device. Utility Model Content

[0005] The purpose of this invention is to provide a pipe welding and turning device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A pipe welding and turning device includes a frame, a controller fixedly mounted on the frame, and a turning assembly disposed on the frame, the turning assembly comprising: A mounting plate is fixedly installed on the top of the frame. A vertical frame is fixedly installed on the top of the mounting plate. Multiple sets of mounting plates and vertical frames are provided. A rotating shaft is rotatably installed inside the vertical frame via bearing components. Each set of vertical frames has four rotating shafts. Two of the rotating shafts are fixedly installed with drive rollers, and these two rotating shafts are fixedly installed on the output end of a servo asynchronous motor. The servo asynchronous motor is fixedly installed on the outer wall of the vertical frame. One of the rotating shafts is fixedly installed with a driven roller, and another rotating shaft is fixedly installed with an adjusting roller. The drive roller, driven roller, and adjusting roller are all covered with rubber sleeves.

[0007] In a further embodiment, the driven roller and the adjusting roller are located on either side of the two driving rollers.

[0008] In a further embodiment, the driven roller and the adjusting roller are positioned at a higher height than the two driving rollers, thereby improving welding efficiency.

[0009] In a further embodiment, the two sets of active rollers, driven rollers, and adjusting rollers roll and fit against both ends of the pipe body to distribute the weight of the pipe and prevent deformation.

[0010] In a further embodiment, the support frame is provided with an adjustment assembly, which includes a fixing block. The fixing block is fixedly installed on the outer wall of the support frame, and a threaded post runs through the inside of the fixing block. A first nut and a second nut are threaded onto the threaded post, and the first nut and the second nut are respectively attached to the upper and lower surfaces of the fixing block.

[0011] In a further embodiment, a bearing sleeve is fixedly installed at the bottom of the threaded column. Two sets of the fixing block, threaded column, first nut, second nut, and bearing sleeve are provided. The two ends of the rotating shaft on the adjusting roller are rotatably installed inside the two sets of bearing sleeves through bearing components. A through groove is provided on the upright frame, and the rotating shaft on the adjusting roller passes through the groove.

[0012] In a further embodiment, a rectangular cover is fixedly installed on the support frame, and a cover plate is snapped onto the rectangular cover. The servo asynchronous motor is located inside the rectangular cover, which can accommodate pipes of more diameters and improve adaptability.

[0013] Compared with the prior art, the present invention provides a pipe welding and turning device, which has the following beneficial effects: 1. This pipe welding and turning equipment, in order to improve welding efficiency, is equipped with a turning component. When the servo asynchronous motor is started, it works with the corresponding rotating shaft to make the active roller rotate. At the same time, multiple sets of driven rollers and adjusting rollers work together to limit and lift the pipe, distributing the weight of the pipe and preventing pipe deformation. The active roller drives the pipe to rotate at a uniform speed through friction, so that the weld seam is always in the best horizontal welding position, replacing manual turning and thus improving welding efficiency.

[0014] 2. To improve the adaptability of this pipe welding and turning equipment, an adjustment component is set up. When the threaded column is moved up and down inside the fixed block to the target height, the first nut and the second nut are tightened, so that the threaded column drives the bearing sleeve to stay stable in that position. Thus, the adjusting roller and the corresponding rotating shaft are fixed in the target position inside the slide groove, thereby changing the height of the adjusting roller from the ground and the distance between it and the active roller, adapting to pipes of more diameters, improving adaptability, and working with the rectangular cover and cover plate to better disassemble and maintain the servo asynchronous motor.

[0019] Please see Figures 1-4 This utility model provides a technical solution: A pipe welding and turning device includes a frame 1, on which a controller 2 is fixedly installed.

[0020] In one embodiment of this utility model, a flipping assembly 3 is provided on the frame 1. The flipping assembly 3 includes a mounting plate 31, which is fixedly mounted on the top of the frame 1. A vertical frame 32 is fixedly mounted on the top of the mounting plate 31. Two sets of mounting plates 31 and vertical frames 32 are provided. A rotating shaft 33 is rotatably mounted inside the vertical frame 32 through bearing components. Four rotating shafts 33 are provided on a single set of vertical frames 32. Two of the rotating shafts 33 are fixedly mounted with drive rollers 34, and both of the two rotating shafts 33 are fixedly mounted on the output end of a servo asynchronous motor 35. The servo asynchronous motor 35 is fixedly mounted on the outer wall of the vertical frame 32. A driven roller 36 is fixedly installed on one of the rotating shafts 33, and an adjusting roller 37 is fixedly installed on another rotating shaft 33. The driven roller 34, driven roller 36, and adjusting roller 37 are all covered with rubber sleeves 38. In addition, the driven roller 36 and adjusting roller 37 are located on both sides of the two driven rollers 34. Furthermore, the driven roller 36 and adjusting roller 37 are at a higher height than the two driven rollers 34, thereby improving welding efficiency. In addition, the two sets of driven rollers 34, driven rollers 36, and adjusting roller 37 roll and fit against both ends of the pipe body, distributing the weight of the pipe and preventing pipe deformation.

[0021] In one embodiment of this utility model, an adjustment component 4 is provided on the support frame 32. The adjustment component 4 includes a fixing block 41, which is fixedly installed on the outer wall of the support frame 32. A threaded post 42 passes through the inside of the fixing block 41. A first nut 43 and a second nut 44 are threadedly fitted on the threaded post 42. The first nut 43 and the second nut 44 are respectively attached to the upper and lower surfaces of the fixing block 41. In addition, a bearing sleeve 45 is fixedly installed at the bottom of the threaded post 42. Two sets of fixing blocks 41, threaded posts 42, first nuts 43, second nuts 44 and bearing sleeves 45 are provided. The two ends of the rotating shaft 33 on the adjusting roller 37 are rotatably installed inside the two sets of bearing sleeves 45 through bearing components. A through groove 46 is opened on the support frame 32, and the rotating shaft 33 on the adjusting roller 37 passes through the groove 46. In addition, a rectangular cover 47 is fixedly installed on the support frame 32. A cover plate 48 is snapped onto the rectangular cover 47. The servo asynchronous motor 35 is located inside the rectangular cover 47, which can accommodate more diameter pipes and improve adaptability.

[0022] Working principle: Before starting the equipment, the diameter of the pipe to be welded needs to be adjusted using the adjusting component 4. During operation, first loosen the first nut 43 and the second nut 44 that are attached to the upper and lower surfaces of the fixed block 41, so that the threaded column 42 can move freely up and down inside the fixed block 41. According to the pipe diameter requirements, push the threaded column 42 to drive the bearing sleeve 45 to move synchronously along the slide groove 46 on the stand 32 until the rotating shaft 33 rotatably connected to the bearing sleeve 45 and the adjusting roller 37 sleeved on the rotating shaft 33 reach the target height. At this time, the distance between the adjusting roller 37 and the driving roller 34 is adapted to the pipe to be processed. After the position is determined, tighten the first nut 43 and the second nut 44 respectively, and lock them in place with double nuts. The mechanism ensures that the threaded post 42 is stable within the fixing block 41, thereby fixing the adjusting roller 37 to the target position and completing the equipment adaptation adjustment. If subsequent maintenance of the servo asynchronous motor 35 is required, the cover plate 48 that is snapped with the rectangular cover 47 can be directly removed, and the cover plate 48 can be snapped back on after the operation is completed. After the adjustment is completed, the two ends of the pipe to be welded are placed on the bearing structure of the two sets of flipping components 3 respectively, so that the bottom of the pipe rolls and contacts the active roller 34, the driven roller 36 and the adjusting roller 37 simultaneously. Since the driven roller 36 and the adjusting roller 37 are located on both sides of the two active rollers 34 and are at a slightly higher height than the active rollers 34, the three form a triangular limiting structure, which works in conjunction with the active roller 34, the driven roller 36 and the adjusting roller 37. The rubber sleeve 38 covering the outside of the roller 37 not only provides stable support for the pipe but also increases the friction between the rubber sleeve and the pipe surface, while distributing the weight of the pipe to prevent deformation due to excessive force at a single point. After the pipe is positioned, the controller 2 on the frame 1 sends a start signal to the servo asynchronous motor 35. The controller 2 uses a conventional PLC control protocol to interact with the servo asynchronous motor 35, ensuring accurate command transmission. After the servo asynchronous motor 35 starts, its output drives the rotating shaft 33, which is fixedly connected to it, to rotate synchronously. The rotating shaft 33 drives the active roller 34 sleeved on it to rotate accordingly. Under the friction between the active roller 34 and the pipe surface, the pipe is driven to rotate evenly around its own axis. The pipe rotates at high speed, while the driven roller 36 and the adjusting roller 37 are passively rotated with the rotating shaft 33 under the drive of the pipe, further assisting the pipe in maintaining a stable rotation state. The pipe rotates at a uniform speed under the synergistic action of the driving roller 34, the driven roller 36 and the adjusting roller 37, which can keep the weld seam on the pipe in the best horizontal welding position at all times. There is no need to manually flip the pipe, which effectively improves the welding efficiency. During the welding process, the controller 2 monitors the operating status of the servo asynchronous motor 35 in real time to ensure that its speed is stable, thereby ensuring that the pipe rotates at a uniform speed and providing a guarantee for the welding quality. In addition to increasing the friction, the rubber sleeve 38 can also protect the surface of the pipe in this process, avoiding direct contact between the metal roller and the pipe and causing scratches.After the pipe welding operation is completed, a stop signal is sent via controller 2, causing the servo asynchronous motor 35 to stop operating. The active roller 34 then stops rotating, terminating the pipe's rotation. The welded pipe is then removed from the roller assembly. If pipes of different diameters need to be processed subsequently, the operation process of adjusting component 4 can be repeated for refitting. If the equipment is not in use, the power to controller 2 is turned off, completing the operation. Throughout the entire process, frame 1 provides stable support for the equipment, controller 2 acts as the control core to achieve coordinated operation of all electrical components, and the flipping component 3 and adjusting component 4 have clearly defined roles, ensuring improved welding efficiency while flexibly adjusting to meet the processing needs of different pipe specifications, thus achieving efficient and convenient auxiliary pipe welding operations.

[0023] All electrical components appearing in this application are electrically connected to the controller 2 and the 220V mains power.
