Description

Technical Field

[0001] This invention relates to the technical field of end seam welding, and more particularly to an intelligent seam welding device for short-side ends with high flange spread using a notched seam welding wheel. Background Technology

[0002] Power transformers are core equipment in power transmission and distribution systems. Key components such as their oil tanks and plate radiators require excellent sealing performance and heat dissipation efficiency to ensure long-term stable operation and prevent safety hazards caused by insulating oil leakage. Plate radiators and corrugated oil tanks often employ a high-flanged structure design. This structure effectively increases the heat dissipation area and strengthens the structural strength of components, adapting to the trend of high-power and miniaturized transformers, and is widely used in the manufacture of medium and large-sized power transformers.

[0003] The sealing reliability of high-flanged laminated components mainly relies on seam welding, with seam welding wheel (roller electrode) seam welding being the mainstream welding method in the industry. Its core principle involves using paired roller electrodes to clamp the thin plate to be welded, utilizing the resistance heat generated during electrode rolling to melt the area to be welded, forming a continuous lapped weld nugget, thereby achieving the sealing and connection of the component. This process has advantages such as high welding efficiency, good weld continuity, and suitability for mass production, making it the core process in the welding of high-flanged laminated components for transformers.

[0004] In existing technologies, seam welding wheels mostly employ flat rollers or simple single-sided chamfered rollers, primarily suitable for welding sheet components with no or low flanges. For high-flange structures, the industry has not yet developed a mature standardized welding solution, and traditional low-flange welding equipment and processes are mostly used, with only manual positioning and slow-down welding methods providing a barely adequate fit. It should be noted that existing traditional seam welding wheels inevitably encounter geometric interference problems when welding high-flange sheet components, and the angular changes caused by the high-flange structure will have a significant negative impact on welding quality and efficiency. Summary of the Invention

[0005] In view of the problems of geometric interference and angle change in the welding process of high-flanged sheet by the existing seam welding wheel, an intelligent seam welding device for the short side end of high-flanged sheet using a notched seam welding wheel is proposed.

[0006] This application provides an intelligent seam welding device for the short side end of a high-flanged sheet using a notched seam welding wheel. The purpose is to: eliminate geometric interference by setting up a seam welding unit, avoid contact and jamming between the seam welding wheel and the high-flanged sheet, ensure welding continuity, extend equipment service life, reduce maintenance costs, and at the same time ensure that the seam welding wheel is always perpendicular to the area to be welded, optimize weld formation, reduce welding defect rate, improve weld sealing performance and structural strength, and ensure the reliability of component operation.

[0007] The technical solution of the present invention is as follows: a high-flanged, short-side intelligent seam welding device using a notched seam welding wheel, comprising a transmission frame, an end seam welding machine disposed on the side wall of the transmission frame, and a seam welding unit disposed on the end seam welding machine, wherein the seam welding unit comprises a seam welding component and an angle adjustment component disposed on the end seam welding machine; The seam welding component includes a seam welding machine frame set at the upper end of the end seam welding machine, pneumatic pressure cylinders set at the upper and lower ends of the seam welding machine frame, mounting blocks hinged to the telescopic ends of the two pneumatic pressure cylinders, seam welding wheels set on the side walls of the two mounting blocks, a servo motor set on the mounting blocks, and a transmission gear set on the drive end of the servo motor and the outer wall of the seam welding wheel. The two transmission gears mesh with each other, the pneumatic pressure cylinder is used to control the vertical position adjustment of the seam welding wheel, the servo motor is used to control the rotation of the seam welding wheel, and notches are provided on both the upper and lower sides of the seam welding wheel, the notches being able to fit against the root of the high flange end.

[0008] Furthermore, the angle adjustment component includes a support plate disposed on the side wall of the seam welding machine frame, a support rod disposed on the upper end of the support plate, a movable rod slidably mounted on the support rod, and a steering sleeve disposed at one end of the movable rod. The curvature of the steering sleeve is exactly the same as the curvature of the high flange area of ​​the sheet. A triggering component is installed at the end of the movable rod away from the steering sleeve. A transmission component is installed between the seam welding machine frame and the steering sleeve.

[0009] Furthermore, the triggering assembly includes a trigger plate disposed at one end of the movable rod, a limiting rod slidably disposed on the trigger plate, a connecting plate disposed at one end of the limiting rod, a contact rod disposed at the lower end of the connecting plate, the contact rod being slidably mounted on the trigger plate, a mating release element being installed on the side wall of the support rod, and a driving element being installed between the transmission frame and the limiting rod.

[0010] Furthermore, the release element includes a transverse plate disposed on the side wall of the support rod and a pressure plate disposed on the side wall of the transverse plate. When the contact rod moves in the horizontal direction and comes into contact with the pressure plate, the contact rod is subjected to compressive force and moves in the vertical upward direction.

[0011] Furthermore, the driving element includes a support plate disposed on the transmission frame and a driving rod disposed at the lower end of the support plate. The driving rod is L-shaped, and the lower end of the driving rod is at the same height as the limiting rod. When the driving rod moves horizontally along the support plate, the limiting rod will move synchronously with the driving rod. The support plate is used to support the workpiece moving on the transmission frame.

[0012] Furthermore, the transmission assembly includes a fixed plate disposed on the upper end of the seam welding machine frame, a rotating shaft rotatably disposed on the fixed plate, an adjusting disc disposed on the side wall of the rotating shaft, a sensing shaft disposed on the side wall of the adjusting disc, the sensing shaft being located inside the steering sleeve, a reset element being installed at one end of the rotating shaft, and a connecting element being installed between the rotating shaft and the mounting block.

[0013] Furthermore, the reset element includes a square plate disposed on the frame of the seam welding machine, and a torsion spring disposed between the side wall of the square plate and the side wall of the rotating shaft, the torsion spring being used to reset the rotating shaft.

[0014] Furthermore, the connecting element includes a vertical rod disposed on the side wall of the rotating shaft, and a connecting rod disposed between the vertical rod and the mounting block.

[0015] The beneficial effects of the present invention.

[0016] 1. By creating notches on both the upper and lower sides of the welding wheel, the "stepped" outward contour of the high-flanged edge's fitting end root can be precisely avoided, solving the core problem of traditional welding wheels contacting and jamming with the high-flanged edge sidewall, thus completely eliminating geometric interference. The size of the notches precisely matches the contour of the high-flanged edge's end root, allowing the welding wheel to smoothly avoid the flange structure, ensuring smooth rolling of the welding wheel during welding. Frequent manual stops for repositioning are unnecessary, effectively preventing welding interruptions and equipment failures caused by interference. Simultaneously, eliminating interference significantly reduces the wear of the welding wheel, extending electrode lifespan, reducing equipment maintenance costs and downtime, providing a reliable guarantee for continuous welding of high-flanged sheet components, and adapting to the needs of large-scale production.

[0017] 2. By perfectly aligning the curvature of the steering sleeve with that of the high flange, and combining this with the linkage effect of the trigger component driving the horizontal movement of the steering sleeve, precise and real-time adjustment of the welding wheel angle can be achieved. This solves the problem that traditional welding wheels cannot adapt to changes in the high flange curvature and have excessive angle deviations. The trigger component can synchronously drive the steering sleeve to move horizontally according to the curvature changes of the welding area, thereby driving the welding wheel to adjust its angle. This ensures that the welding wheel is always perpendicular to the area to be welded, so that the electrode pressure is applied evenly to the welding surface, the current path is stable, the weld penetration is uniform, and the weld formation is regular. This significantly improves the density and structural strength of the weld, reduces the risk of transformer insulating oil leakage, and ensures the long-term operational reliability of high flange components.

[0018] 3. By linking the angle adjustment component with the trigger assembly and the steering sleeve, the angle of the welding wheel is automatically adjusted, eliminating the need for manual intervention. This significantly reduces labor intensity and improves welding continuity and ease of operation. The trigger assembly responds in real-time to changes in the curvature of the high flange area, automatically driving the steering sleeve to move horizontally, thereby synchronously adjusting the angle of the welding wheel. No manual intervention is required throughout the process, avoiding downtime caused by manual adjustments, ensuring the continuity of the welding process, reducing human error, and ensuring stable welding quality.

[0021] 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.

[0022] Example 1, referring to Figures 1-5 The first embodiment of the present invention provides an intelligent seam welding device for the short side end of a high-flanged sheet using a notched seam welding wheel, including a transmission frame 1, an end seam welding machine 2 fixedly installed on the side wall of the transmission frame 1, and a seam welding unit installed on the end seam welding machine 2. The seam welding unit includes a seam welding component and an angle adjustment component installed on the end seam welding machine 2.

[0023] The seam welding component includes a seam welding machine frame 101 fixedly installed on the upper end of the end seam welding machine 2, pneumatic pressure cylinders 102 fixedly installed at the upper and lower ends of the seam welding machine frame 101, mounting blocks 103 hinged to the telescopic ends of the two pneumatic pressure cylinders 102, seam welding wheels 104 rotatably installed on the side walls of the two mounting blocks 103, a servo motor 105 fixedly installed on the mounting blocks 103, and a transmission gear 106 fixedly installed on the drive end of the servo motor 105 and the outer wall of the seam welding wheel 104.

[0024] Two transmission gears 106 mesh with each other. The pneumatic pressure cylinder 102 is used to control the vertical position adjustment of the seam welding wheel 104. The servo motor 105 is used to control the rotation of the seam welding wheel 104. Notches are provided on both the upper and lower sides of the seam welding wheel 104. The notches are used to fit into the root of the high flange end.

[0025] Specifically, when welding flake-shaped ends, the standard seam welding wheel 104 (disc electrode) typically fails to effectively adhere to the weld root. The core reason is the fundamental conflict between its geometry and the structure of the flake-shaped end, preventing contact with the root and pressure transmission, thus hindering effective welding. The seam welding wheel 104 is disc-shaped, with a working surface that is mostly cylindrical or spherical, possessing a large radius and thickness. This allows it to only fit open, smooth surfaces such as planes and outer circles, making it difficult to penetrate narrow areas. Flake-shaped ends often have high flanges or folded edges, with the root located at an inner corner or deep groove—a narrow, concave dead zone. When the welding wheel presses against the end, the outer edge first contacts the sidewall, forming a "bridge," preventing the central working surface from reaching the root and creating a physical contact barrier.

[0026] Meanwhile, seam welding relies on pressure and resistance heat to achieve welding. The root being suspended causes pressure to concentrate at the surface edge, resulting in insufficient pressure at the root. Poor contact can also lead to excessive contact resistance, causing problems such as localized overheating and arcing, preventing effective fusion from forming at the root. Furthermore, the continuous rolling required for seam welding necessitates a smooth contact surface. The corners and dead angles at the root prevent the welding wheel from rolling smoothly, further hindering welding at the root.

[0027] The structure of the standard seam welding wheel 104 creates a process blind spot, making it unsuitable for the special structure of the root of the sheet-like end. The root welding problem can be solved by alternative solutions such as using small-head electrode spot welding, argon arc welding, custom-designed contour welding wheels, or optimizing the end structure.

[0028] However, welding the root by electric welding or other methods will affect the overall welding efficiency and quality, while increasing the workload and production cost. By using the structural design of the notch-type seam welding wheel 104, the avoidance-type drive welding wheel and the automatic positioning method to work together, the technical problems such as interference, incomplete root penetration, large deformation and low efficiency that exist when welding high flange products with traditional argon arc welding and ordinary seam welding machines are solved, and the high efficiency of sealing welding of the short side end of high flange pieces is achieved.

[0029] Example 2, refer to Figures 2-8 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the angle adjustment component includes a support plate 201 fixedly installed on the side wall of the seam welding machine frame 101, a support rod 202 fixedly installed on the upper end of the support plate 201, a movable rod 203 slidably installed on the support rod 202, and a steering sleeve 204 fixedly installed on one end of the movable rod 203. The curvature of the steering sleeve 204 is exactly the same as the curvature of the high flange area of ​​the sheet. A triggering component is installed at the end of the movable rod 203 away from the steering sleeve 204. A transmission component is installed between the seam welding machine frame 101 and the steering sleeve 204.

[0030] The triggering assembly includes a trigger plate 205 fixedly installed at one end of the movable rod 203, a limit rod 206 slidably installed on the trigger plate 205, a connecting plate 207 fixedly installed at one end of the limit rod 206, a contact rod 208 fixedly installed at the lower end of the connecting plate 207, the contact rod 208 slidably installed on the trigger plate 205, a mating release element installed on the side wall of the support rod 202, and a driving element installed between the transmission frame 1 and the limit rod 206.

[0031] The release element includes a horizontal plate 301 fixedly installed on the side wall of the support rod 202, and a pressure plate 302 fixedly installed on the side wall of the horizontal plate 301. When the contact rod 208 moves in the horizontal direction and comes into contact with the pressure plate 302, the contact rod 208 is subjected to compressive force and moves in the vertical upward direction.

[0032] The driving element includes a support plate 303 fixedly mounted on the transmission frame 1, and a driving rod 304 fixedly mounted on the lower end of the support plate 303. The driving rod 304 is L-shaped, and the lower end of the driving rod 304 is at the same height as the limiting rod 206. When the driving rod 304 moves horizontally along with the support plate 303, the limiting rod 206 will move synchronously with the driving rod 304. The support plate 303 is used to support the workpiece moving on the transmission frame 1. The support plate 303 is fixedly mounted above the transmission belt of the transmission frame 1, so that the transmission belt of the transmission frame 1 can drive the support plate 303 to move synchronously.

[0033] The transmission assembly includes a fixed plate 401 fixedly mounted on the upper end of the seam welding machine frame 101, a rotating shaft 402 rotatably mounted on the fixed plate 401, an adjusting disc 403 fixedly mounted on the side wall of the rotating shaft 402, and a sensing shaft 404 fixedly mounted on the side wall of the adjusting disc 403. The sensing shaft 404 is located inside the steering sleeve 204. A reset element is installed at one end of the rotating shaft 402, and a connecting element is installed between the rotating shaft 402 and the mounting block 103. The reset element includes a square plate 405 fixedly mounted on the seam welding machine frame 101, and a torsion spring 406 fixedly mounted between the side wall of the square plate 405 and the side wall of the rotating shaft 402. The torsion spring 406 is used to reset the rotating shaft 402. The connecting element includes a vertical rod 407 fixedly mounted on the side wall of the rotating shaft 402, and a connecting rod 408 fixedly mounted between the vertical rod 407 and the mounting block 103.

[0034] Specifically, the end is located above the support plate 303 and moves above the transmission frame 1 along with the support plate 303. When the support plate 303 drives the welding area of ​​the upper end to be directly below the corresponding seam welding wheel 104, the driving rod 304 below the support plate 303 comes into contact with the limiting rod 206. This allows the driving rod 304 to move synchronously with the steering sleeve 204 at one end of the movable rod 203 through the limiting rod 206 during the subsequent horizontal movement. The curvature of the steering sleeve 204 is exactly equal to the flange curvature of the end. When the seam welding wheel 104 is welding the welding area of ​​the end, and the end is adjusting the welding area during the horizontal movement, the angle changed by the steering sleeve 204 relative to the seam welding wheel 104 is exactly the same as the flange angle at the corresponding area, thus ensuring that the seam welding wheel 104 is always perpendicular to the flange area.

[0035] By perfectly aligning the curvature of the steering sleeve 204 with the curvature of the high flange, and combining this with the linkage effect of the trigger component driving the horizontal movement of the steering sleeve 204, precise and real-time adjustment of the angle of the welding wheel 104 can be achieved. This solves the problem that traditional welding wheels 104 cannot adapt to changes in the curvature of the high flange and have excessive angle deviations. The trigger component can synchronously drive the steering sleeve 204 to move horizontally according to the curvature changes of the welding area, thereby driving the welding wheel 104 to adjust its angle. This ensures that the welding wheel 104 is always perpendicular to the area to be welded, so that the electrode pressure is applied evenly to the welding surface, the current path is stable, the weld penetration is uniform, and the weld formation is regular. This significantly improves the density and structural strength of the weld, reduces the risk of transformer insulating oil leakage, and ensures the long-term operational reliability of high flange components.

[0036] By linking the angle adjustment component with the trigger assembly and the steering sleeve 204, the angle of the welding wheel 104 is automatically adjusted, eliminating the need for manual intervention. This significantly reduces labor intensity and improves welding continuity and ease of operation. The trigger assembly responds in real-time to changes in the curvature of the high flange area, automatically driving the steering sleeve 204 to move horizontally, thereby synchronously adjusting the angle of the welding wheel 104. The entire process requires no manual intervention, avoiding downtime caused by manual adjustments, ensuring welding continuity, reducing human error, and guaranteeing stable welding quality.

[0037] The remaining structure is the same as that in Example 1.

[0038] Based on embodiments 1-2, the working principle of the present invention is as follows: The end to be welded is placed above the corresponding support plate 303. The transmission frame 1 drives the upper end to move to the interior of the corresponding end welding machine 2 through the support plate 303. When the area to be welded on the end is just below the welding wheel 104, the driving rod 304 at the lower end of the support plate 303 just contacts the limiting rod 206. This allows the moving rod 203 to move synchronously through the limiting rod 206 when the end moves horizontally to adjust the welding area.

[0039] When the flanged area of ​​the end needs to be welded, the transmission frame 1 drives the end to continue moving horizontally. At the same time, the driving rod 304 exerts horizontal pressure on the limiting rod 206, causing the limiting rod 206 to drive the movable rod 203 to move horizontally synchronously, which in turn drives the steering sleeve 204 to move synchronously. When the flanged area of ​​the end is directly below the welding wheel 104, the steering sleeve 204 moves horizontally by the same distance, which causes the steering sleeve 204 to make the welding wheel 104 change angles equally through the sensing shaft 404. This ensures that no matter what angle the flanged area of ​​the end is below the welding wheel 104, the steering sleeve 204 and the sensing shaft 404 cooperate to make the welding wheel 104 adaptively adjust according to the flange angle, ensuring that the welding wheel 104 is always perpendicular to the flanged area with an angle, thus ensuring welding efficiency.

[0040] After the welding wheel 104 completes the welding of the flanged area, the contact rod 208 comes into contact with the horizontal pressure plate 302. Because the contact rod 208 has a chamfer, when the contact rod 208 comes into contact with the pressure plate 302 and continues to move horizontally, the contact rod 208 moves upward after being squeezed. During the movement, the connecting plate 207 drives the limiting rod 206 to move upward synchronously, thereby contacting the limiting rod 206 to limit the driving rod 304. At this time, the torsion spring 406 quickly resets the rotating shaft 402. The moving rod 203, the limiting rod 206, and the steering sleeve 204 quickly reset to prepare for the angle adjustment during the subsequent end welding.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. 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.
