Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and in particular to a continuous laser welding equipment for straight seam welded pipes. Background Technology

[0002] Straight seam welded pipes are core profiles in petroleum, chemical, and municipal engineering fields. Continuous laser welding, with its advantages of a small heat-affected zone and high welding precision, has become the mainstream process for welded pipe processing. Current continuous welded pipe production lines need to take into account multiple pipe diameter adaptations, weld alignment, adaptive angle adjustment, and post-weld treatment. Existing equipment mostly adopts a fixed structure design, with low integration of functional modules, making it difficult to meet the requirements of continuous and high-precision production.

[0003] In existing welding equipment, the extrusion mechanism for extruding pipes cannot adaptively adjust the extrusion pressure for different pipe diameters, which easily causes pipe deformation; the weld precision in the welding process is insufficient, and the welding angle cannot be corrected in real time when the pipe seam deviates; the deburring and cooling shaping after welding need to be completed by independent equipment, which has poor dynamic adjustment capability, resulting in many weld defects and low yield, and failing to meet the needs of efficient continuous production. Summary of the Invention

[0004] To overcome the shortcomings of being unable to adapt to the extrusion pressure of the adjusted pipe diameter, the inability to correct weld seam offset in a timely manner, low efficiency of post-weld processing, and poor dynamic adjustment capability, this invention provides a continuous laser welding equipment for straight seam welded pipes.

The second angle-adjusting sealing rod is slidably connected to the connecting block. An elastic element is provided between the second angle-adjusting sealing rods. A hydraulic oil chamber corresponding to the second angle-adjusting sealing rod is provided inside the connecting block. The symmetrically distributed first and second angle-adjusting sealing rods are both annular.

[0008] To further explain, the outer periphery of the detection wheel is provided with a radially outward protruding annular ridge, which is used to extend into the pipe gap to detect the alignment status of the pipe gap.

[0009] To further explain, a trigger hydraulic rod is provided inside the adjusting housing, and the telescopic end of the trigger hydraulic rod is fixedly connected to the spring frame. An adjusting hydraulic rod is provided inside the swing arm, and the telescopic end of the adjusting hydraulic rod is fixedly connected to the laser welding gun. The trigger hydraulic rod and the adjusting hydraulic rod are connected.

[0010] Further explanation: the welding processing mechanism includes a fixed shell, which is fixedly connected to the bracket. A sliding shell is slidably connected to the side of the fixed shell away from the swing arm. An annular seat is rotatably connected inside the sliding shell. A scraper is fixedly connected inside the annular seat. A cooling nozzle is provided on the side of the fixed shell near the swing arm. A power component is provided between the fixed shell and the sliding shell. The power component is used to drive the scraper to move. A dynamic adjustment component is provided inside the fixed shell. The dynamic adjustment component is used to adjust the pressure during welding processing.

[0011] To further explain, a worm gear is provided on the annular seat, the scraper is circular, and the circle of the scraper is tangent to the surface of the straight pipe.

[0012] Further explanation: the power assembly includes a lower driving wheel, which is rotatably connected to the fixed housing. A worm gear is rotatably connected inside the sliding housing, and the worm gear is drivingly connected to the worm wheel of the annular seat. A power housing is fixedly connected to the fixed housing, and the power housing is slidably connected to the sliding housing.

A power bevel gear is rotatably connected inside the power housing, and the power bevel gear and the transmission bevel gear are drivingly engaged. The power bevel gear and the lower driving wheel are drivingly connected.

[0013] Further explanation: the dynamic adjustment component includes symmetrically distributed spring rods, which are slidably connected to the fixed shell.

[0015] The beneficial effects of this invention are as follows: By integrating the extrusion mechanism, the angle fine-tuning mechanism and the welding processing mechanism, this invention constructs a continuous laser welding equipment that integrates pipe diameter adaptation, weld detection, angle fine-tuning and post-weld processing. This solves the problems of dispersed functions and cumbersome processes in traditional equipment. Moreover, the overall structure enables continuous operation of welded pipe processing without the need for additional auxiliary equipment, simplifies the production process, improves the stability and efficiency of welding operations, and is suitable for the large-scale production of straight seam welded pipes of various specifications.

[0016] The extrusion mechanism can flexibly adjust the extrusion pressure of different pipe diameters to avoid pipe deformation. Combined with the angle fine-tuning mechanism and the annular convex edge of the detection wheel, it can accurately embed into the pipe seam to complete the alignment detection. Through hydraulic linkage, the welding angle can be adaptively corrected in real time, which effectively solves the problems of pipe seam offset and welding angle mismatch. It can ensure the alignment accuracy of the weld seam without manual intervention, greatly reduce welding defects such as misalignment and incomplete penetration, and improve welding quality and accuracy.

[0017] By integrating the deburring and cooling / shaping functions of the welding processing mechanism, the power component drives the internal cutting scraper to efficiently remove weld burrs. In conjunction with the dynamic adjustment component, the processing pressure is adaptively adjusted to ensure uniform processing force. This solves the problems of post-weld burr residue, pipe deformation, and uneven cooling. The post-weld processing is completed simultaneously, improving the surface quality and dimensional accuracy of the pipe, and enhancing the dynamic adaptability of the equipment and the finished product qualification rate.

Detailed Implementation

[0029] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions herein are used to explain the present invention, but are not intended to limit the present invention.

[0030] Example 1

[0031] A type of continuous laser welding equipment for straight seam welded pipes, such as Figure 1-10As shown, the assembly includes a support 1, a connecting block 2, a swing arm 3, a laser welding gun 4, an adaptive extrusion mechanism 5, an angle fine-tuning mechanism 6, and a welding processing mechanism 7. The connecting block 2 is fixed to the support 1, the swing arm 3 is rotatably connected to the connecting block 2, and the laser welding gun 4 is slidably connected to the upper side of the swing arm 3. Symmetrically distributed fixed rods 301 are fixed to the swing arm 3, and fixed wheels 302 are rotatably connected to each fixed rod 301. The fixed wheels 302 are used to guide the tube blank circumferentially and limit its radial movement, maintain the stability of the tube blank's transport, prevent the tube blank from shifting and shaking, and ensure the accuracy of the joint and welding. The adaptive extrusion mechanism 5 is located on the left side of the connecting block 2 and is used to adaptively adjust the extrusion pressure according to different tube diameters. The welding processing mechanism 7 is located on the right side of the support 1 and is used for processing the straight tube after welding.

[0032] like Figure 3 As shown, the adaptive extrusion mechanism 5 includes an extrusion shell 501 fixed to the left side of the connecting block 2. The extrusion shell 501 is rotatably connected to the swing arm 3. Circumferentially evenly distributed electric telescopic rods 502 are provided inside the extrusion shell 501. The electric telescopic rods 502 are provided with symmetrically distributed telescopic ends. Each telescopic end of the electric telescopic rod 502 is slidably connected to a slider 503. An elastic element, which is a spring, is provided between the slider 503 and the telescopic end of the electric telescopic rod 502. Extrusion wheels 504 are rotatably connected between adjacent sliders 503. The extrusion wheels 504 are used to apply uniform extrusion force to the circumference of the tube blank, so that the edges of the tube blank are tightly fitted to form a weld, providing a stable weld for laser welding. The extrusion amplitude and extrusion force are automatically adjusted according to different tube diameters to ensure that the edges of the tube blank are evenly fitted and the weld is stable, avoiding tube deformation and ensuring the accuracy of the welding base. An angle fine-tuning mechanism 6 is provided inside the extrusion shell 501. The angle fine-tuning mechanism 6 is used to adapt to the welding angle during tube welding.

[0033] like Figures 3-5As shown, the angle fine-tuning mechanism 6 includes an adjusting shell 601 slidably connected to the extrusion shell 501. A spring frame 602 is slidably connected inside the adjusting shell 601. A detection wheel 603 is rotatably connected to the spring frame 602. A radially outwardly protruding annular ridge is provided at the center of the outer periphery of the detection wheel 603. This annular ridge is used to extend into the pipe gap to detect the alignment status of the pipe gap. A first angle-adjusting sealing rod 604 is fixedly connected to the adjusting shell 601 in a symmetrical arrangement. A hydraulic oil chamber corresponding to the first angle-adjusting sealing rod 604 is provided inside the extrusion shell 501. A second angle-adjusting sealing rod 605 is fixedly connected to the swing arm 3. The second angle-adjusting sealing rod 605 is slidably connected to the connecting block 2. A [missing information - likely a typo, should be inserted here] is provided between the second angle-adjusting sealing rods 605. The elastic element is a spring. The connecting block 2 is provided with a hydraulic oil chamber corresponding to the second angle-adjusting sealing rod 605. The first angle-adjusting sealing rod 604 and the second angle-adjusting sealing rod 605 are symmetrically distributed and are both annular. The adjusting shell 601 is provided with a trigger hydraulic rod 606. The telescopic end of the trigger hydraulic rod 606 is fixedly connected to the spring frame 602. The swing arm 3 is provided with an adjusting hydraulic rod 607. The telescopic end of the adjusting hydraulic rod 607 is fixedly connected to the laser welding gun 4. The trigger hydraulic rod 606 and the adjusting hydraulic rod 607 are connected. The offset state of the pipe seam is detected in real time by the detection wheel 603, and the angle and position of the laser welding gun are automatically adjusted by hydraulic linkage to ensure that the laser focus is always accurately aligned with the center of the joint.

[0034] like Figures 6-8 As shown, the welding processing mechanism 7 includes a fixed shell 701 fixed to the bracket 1. A sliding shell 702 is slidably connected to the right side of the fixed shell 701. An annular seat 703 is rotatably connected inside the sliding shell 702. A scraper 704 is fixed inside the annular seat 703. A worm gear is provided on the annular seat 703. The scraper 704 is annular in shape, and the circle of the scraper 704 is tangent to the surface of the straight pipe. The scraper 704 continuously rotates and scrapes with the pipe to uniformly remove burrs and excess height from the weld surface, so that the weld and the outer wall of the pipe are smooth and consistent. A cooling nozzle 8 is provided on the right side of the fixed shell 701 for cooling the pipe after welding. A power component 71 is provided between the fixed shell 701 and the sliding shell 702. The power component 71 is used to drive the scraper 704 to move. A dynamic adjustment component 72 is provided inside the fixed shell 701 for adjusting the pressure during welding processing.

[0035] like Figure 7 and Figure 9As shown, the power assembly 71 includes a lower drive wheel 711 rotatably connected to the fixed housing 701, a worm 712 rotatably connected inside the sliding housing 702, the worm 712 being connected to the worm wheel of the annular seat 703, a power housing 713 fixedly connected to the fixed housing 701, the power housing 713 being slidably connected to the sliding housing 702, a transmission bevel gear 714 rotatably connected inside the power housing 713, the transmission bevel gear 714 being splinedly connected to the worm 712, and a power bevel gear 715 rotatably connected inside the power housing 713, the power bevel gear 715 being in transmission engagement with the transmission bevel gear 714, and the power bevel gear 715 being connected to the lower drive wheel 711. Through the action of the lower drive wheel 711, the continuous movement of the tube body is converted into the rotational power of the scraper 704, requiring no external power source, and is directly proportional to the continuous production efficiency of the tube body.

[0036] like Figure 7 and Figure 10 As shown, the dynamic adjustment component 72 includes spring rods 721 slidably connected to the fixed shell. The spring rods 721 are symmetrically distributed, and an upper moving wheel 722 is rotatably connected between the symmetrically distributed spring rods 721. The outer periphery of the upper moving wheel 722 is provided with a radially inwardly recessed annular groove to avoid burrs and excess height on the surface of the pipe body after welding. The symmetrically distributed spring rods 721 are jointly fixed to an adjustment plate 723. The adjustment plate 723 is slidably connected to the sliding shell 702. An adjustment rod 724 is rotatably connected inside the adjustment plate 723. The adjustment rod 724 is threadedly connected to a spring plate 725. The spring plate 725 is slidably connected to the sliding shell 702. The spring of the spring plate 725 is located between its lower side and the sliding shell 702. By adjusting the position of the spring plate 725, the initial elastic force of the spring plate 725 is adjusted, thereby adaptively matching the pipe diameter change, stabilizing the scraping pressure of the scraper 704, ensuring that the scraper 704 is evenly attached to the pipe wall, and avoiding scratching or incomplete scraping.

[0037] When using this welding equipment, the straight seam tube blank to be welded first enters the equipment along the feeding direction. The fixed wheel 302 of the fixed rod 301 on the swing arm 3 first performs circumferential limiting and guiding of the tube blank, ensuring that the tube blank is stably conveyed along the straight direction, laying the foundation for subsequent welding operations.

[0038] After the tube blank enters the appropriate extrusion mechanism 5, the electric telescopic rods 502, which are evenly distributed circumferentially inside the extrusion shell 501, drive the telescopic ends to extend and retract according to the tube diameter specifications. This causes the slider 503 and the extrusion wheel 504 to move synchronously. The spring between the slider 503 and the telescopic ends of the electric telescopic rods 502 buffers the extrusion pressure in real time, so that the extrusion wheel 504 can circumferentially extrude and form the tube blank with uniform and appropriate pressure. This avoids the tube blank from deforming due to excessive or insufficient extrusion pressure, which would result in poor joint sealing and completes the precise joint sealing operation of the tube blank.

[0039] During the jointing process, the tube blank contact angle fine-tuning mechanism 6's detection wheel 603 maintains constant contact with the tube blank under the elastic force of the spring frame 602. The annular convex ridge at the center of the outer periphery of the detection wheel 603 is embedded inside the tube gap to detect the alignment status of the tube gap in real time. When the tube gap deviates, the edge of the tube gap squeezes the annular convex ridge, causing the detection wheel 603 and the spring frame 602 to move within the adjusting shell 601. This causes the first angle-adjusting sealing rod 604 on the adjusting shell 601 to slide within the hydraulic oil chamber of the extrusion shell 501. The hydraulic oil chamber of the extrusion shell 501 drives the second angle-adjusting sealing rod 605 to slide within the hydraulic oil chamber of the connecting block 2 via hydraulic transmission. The swing arm 3 rotates adaptively around the axis of the extrusion shell 501, ensuring that the welding point of the laser welding gun 4 driven by the swing arm 3 is always aligned with the joint of the tube blank. At the same time, the displacement of the spring frame 602 drives the hydraulic rod 606 to move. Through the hydraulic transmission between the hydraulic rod 606 and the adjusting hydraulic rod 607, the telescopic end of the adjusting hydraulic rod 607 extends and retracts. The telescopic end of the adjusting hydraulic rod 607 drives the laser welding gun 4 to slide and finely adjust on the swing arm 3. The height of the laser welding gun 4 is adaptively adjusted in real time according to different tube diameters, so that it is aligned with the center of the joint of the tube blank. This ensures that the laser focus is always accurately applied to the weld, avoiding welding offset, incomplete penetration, or burn-through due to changes in tube diameter.

[0040] After welding, the pipe enters the welding processing mechanism 7. As the pipe moves, it drives the lower moving wheel 711 to rotate. The lower moving wheel 711 drives the power bevel gear 715 to rotate through transmission. The power bevel gear 715 meshes with the transmission bevel gear 714 to drive the worm gear 712 to rotate. Through the worm gear 712 and the worm wheel of the ring seat 703, the ring seat 703 and the scraper 704 rotate synchronously. The scraper 704 efficiently removes weld burrs in a state of being tangential to the surface of the pipe. The cooling nozzle 8 sprays cooling medium synchronously onto the welding area to quickly cool and shape the weld and the pipe body.

[0041] When the pipe is cooled after welding, the upper moving wheel 722 is in contact with the upper surface of the pipe, and the upper moving wheel 722 avoids the weld burrs at the joint of the pipe through the annular groove. The spring rod 721 adaptively extends and retracts according to the outer diameter of the pipe, driving the adjusting plate 723 and the sliding shell 702 to move synchronously. By rotating the adjusting rod 724, the spring plate 725 is driven to move up and down. The lower the position of the spring plate 725, the greater the spring force between the spring plate 725 and the sliding shell 702, and the greater the pressure of the scraper 704 on the surface of the pipe. Adjusting the pressure during scraping ensures that the scraper 704 adheres to the surface of the pipe with a moderate and uniform force, avoiding insufficient pressure that leads to incomplete burr removal, and preventing excessive pressure that scratches the pipe body and causes pipe deformation, thus improving the stability of post-weld processing and the smoothness of the finished product. This completes the continuous laser welding and processing operation of the straight seam welded pipe.

[0042] By sequentially completing the blank guiding, adaptive extrusion seam closing, real-time weld seam detection and linkage correction of welding gun angle and height, continuous laser welding, and post-weld burr removal and cooling shaping, high-precision, automated, continuous and stable production of straight seam welded pipes of different specifications is finally achieved.
