Description

Technical Field

[0001] This invention relates to the field of steel structure processing technology, specifically to an integrated forming device and method for steel structure nodes based on electric arc fused wire. Background Technology

[0002] Steel structures, with their advantages of high strength, large span, convenient construction, and high recyclability, are widely used in various fields such as building construction, bridge construction, and marine engineering. As the core component connecting various steel structural members, the forming quality of steel structure nodes directly determines the load-bearing capacity and safety of the entire steel structure system. Arc welding technology, due to its high welding efficiency and excellent joint performance, has become one of the mainstream processes for forming steel structure nodes, and corresponding integrated forming devices have become a key research and development focus in the industry.

[0003] Currently, most existing steel structure node forming devices based on electric arc fuses consist of a base, an electric arc fuse device, and a simple fixing mechanism. The main working process is as follows: the two steel structures to be welded are transferred to the preset position by a crane, the steel structures are initially positioned and clamped by the fixing mechanism, the docking angle and position of the two steel structures are adjusted, and the electric arc fuse device is started to carry out the welding operation. During the welding process, the posture of the steel structures is adjusted manually or by a simple drive structure to ensure the integrity of the welding.

[0004] However, existing forming devices have significant technical shortcomings in practical applications, making it difficult to meet the high-efficiency and precise processing requirements of large steel structure nodes. On the one hand, large steel structure components are large in size and heavy in weight, making it difficult to fix the steel structure to the fixing mechanism. Moreover, the fixed structure design of the fixing mechanism cannot flexibly adjust the fixing position according to the cross-sectional shape and size of the steel structure, resulting in difficulties in clamping the steel structure and making it difficult to achieve coaxial positioning between the fixing mechanism and the steel structure. The clamping firmness and coaxiality are insufficient, affecting the accuracy of subsequent welding and butt jointing. On the other hand, existing devices are usually equipped with only one set of fixing mechanisms, and clamping and welding operations cannot be carried out in parallel. It is necessary to wait for the welding of one set of steel structures to be completed before the clamping of the next set of steel structures can be carried out. The long operation interval significantly reduces the processing efficiency of steel structure nodes and increases production time costs.

[0005] Therefore, it is necessary to provide an integrated forming device and method for steel structure nodes based on electric arc fused wire to solve the above-mentioned technical problems. Summary of the Invention

[0016] A method for integrated forming of steel structure nodes based on electric arc fuses, employing any of the aforementioned integrated forming devices for steel structure nodes based on electric arc fuses, includes the following steps: S1.

The fixing cylinders are fixed to the steel structures by fixing components to achieve the positioning of the fixing cylinders and the steel structures. S2. Rotate the upper arc-shaped support plate to open the ring bracket. Move the steel structure with the crane to move the fixed cylinder to the corresponding limit position of the lower arc-shaped support plate.

After the two steel structures are fixed in the two ring supports respectively, adjust the spatial angle of the two steel structures to the preset welding posture, drive the sliding frame to move smoothly towards the fixed frame through the drive component, so that the welding end faces of the two steel structures are connected, and then start the arc welding wire equipment to perform the welding wire operation to achieve the integrated forming of the steel structure node. S4. During the welding process, the two fixed cylinders are driven to rotate synchronously by the drive component two, which in turn drives the two steel structures to rotate synchronously to switch the welding position.

[0017] In summary, the present invention has the following beneficial effects: The invention utilizes a sliding fixing component along a circular track, allowing for flexible adjustment of the fixing component's spatial position according to the cross-sectional shape and size of the steel structure. This ensures a tight fit between the fixing component and the steel structure surface, significantly improving the firmness and coaxiality of the steel structure clamping. Simultaneously, the detachable fixing cylinder enables the steel structure to be fixed and positioned when lifted by a crane, effectively solving the problem of difficult clamping of large steel structures. This improves welding precision and ensures the forming quality of steel structure nodes, while significantly expanding the device's adaptability to steel structures of different specifications and cross-sectional types. By configuring multiple fixing cylinders, clamping and welding operations can be carried out in parallel. While one group of steel structures is being welded, another group of steel structures to be welded can be simultaneously clamped and fixed to the fixing cylinders. After the previous group is welded, the clamped steel structure can be immediately transferred for welding, significantly shortening the operation interval time. This significantly improves the processing efficiency of steel structure nodes and reduces production time costs, while eliminating the need for additional complex equipment, thus balancing the device's practicality and economy. This invention utilizes a hollow annular transmission airbag, piston one, piston two, cylinder, air cylinder, and various infusion channels and pipelines to form a closed hydraulic transmission circuit, enabling controllable adjustment of the annular transmission airbag's expansion and contraction state: when the cylinder is not under pressure, the annular transmission airbag is in a contracted state, allowing for convenient manual rotation of the fixed cylinder to adjust the steel structure angle, effectively reducing the operational difficulty of steel structure angle calibration, ensuring the level is quickly calibrated to a horizontal state, and guaranteeing the steel structure's docking accuracy; after angle calibration, the cylinder drives the hydraulic oil flow to cause the two annular transmission airbags to expand synchronously, achieving close contact with the outer wall of the fixed cylinder and applying a preset pressure, thus achieving a reliable transmission effect.

[0020] The present invention will be further described below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] Please see Figures 1-5 In this embodiment of the invention, an integrated steel structure node forming device based on electric arc fuse includes a base 1, a fixed support 3 and a sliding support 2 disposed above the base 1, a driving assembly for driving the sliding support 2 to move horizontally, and an electric arc fuse device disposed on the base 1. The fixed support 3 is fixedly connected to the base 1. Both the fixed support 3 and the sliding support 2 are equipped with annular brackets 4 at their top ends. A fixed cylinder 5 is rotatably disposed on the inner side of the annular bracket 4. Both ends of the fixed cylinder 5 are fixedly disposed with annular tracks 502, and sliding devices are slidably disposed on the annular tracks 502. There are multiple fixing components for fixing the steel structure. The annular bracket 4 includes an upper arc-shaped support plate 402, a lower arc-shaped support plate 401, and a locking component for locking the upper arc-shaped support plate 402. The lower arc-shaped support plate 401 is fixedly connected to the sliding stand 2 or the fixed stand 3. The lower arc-shaped support plate 401 and the upper arc-shaped support plate 402 are hinged together by a hinge 403. The base 1 is provided with a second driving component for driving the fixed cylinder 5 to rotate. The device is equipped with multiple fixed cylinders 5. The working principle is as follows: In specific use, the two steel structures to be welded are first lifted by a crane. The steel structure is lifted and then the two fixing cylinders 5 are respectively fitted onto the two steel structures. The fixing cylinders 5 are fixed to the steel structures using fixing components, achieving coaxial positioning of the fixing cylinders 5 and the steel structures. Then, the upper arc-shaped support plate 402 is rotated to open the annular bracket 4. The steel structure is moved by the crane, which moves the fixing cylinders 5 to the corresponding limit position of the lower arc-shaped support plate 401. The upper arc-shaped support plate 402 is then reset and locked using locking components, thereby detachably limiting the fixing cylinders 5 within the annular bracket 4, completing the initial clamping of the steel structure. After the two steel structures are respectively fixed to the two annular brackets... After the two steel structures are placed inside the support bracket 4, the spatial angle of the two steel structures is adjusted to the preset welding posture. The sliding support 2 is driven by the drive component 1 to move smoothly towards the fixed support 3, so that the welding end faces of the two steel structures are accurately connected. After the connection accuracy meets the requirements of arc wire welding, the arc wire welding equipment is started to perform the arc wire welding operation, realizing the integrated forming of the steel structure node. During the welding process, the two fixed cylinders 5 are driven by the drive component 2 to rotate synchronously and at the same speed, thereby driving the two steel structures to rotate synchronously, so that the welding position is switched evenly, ensuring the continuity and consistency of the welded joint and improving the welding quality.

[0022] The core benefits of this solution are as follows: By using a fixed component that can slide along the annular track 502, the spatial position of the fixed component can be flexibly adjusted according to the cross-sectional shape and size of the steel structure, ensuring that the fixing block 16 in the fixed component is in close contact with the surface of the steel structure, greatly improving the firmness and coaxiality of the steel structure clamping, effectively adapting to steel structures of different specifications and cross-sectional types, and significantly broadening the application range of the device; by configuring multiple fixing cylinders 5, the clamping operation and welding operation can be carried out in parallel, that is, while one group of steel structures is being welded, another group of steel structures to be welded can be clamped and fixed to the fixing cylinder 5 simultaneously. After the first group is welded, the clamped other group of steel structures can be immediately transferred to the annular support 4 for welding, greatly shortening the operation interval time, significantly improving the processing efficiency of steel structure nodes, and reducing production time costs.

[0023] In this embodiment, preferably, the locking assembly includes a locking seat 404, a locking block 405, and a handle 406. The locking seat 404 is fixedly connected to the lower arc-shaped support plate 401, and the locking block 405 is fixedly connected to the upper arc-shaped support plate 402. The locking block 405 is engaged with the locking seat 404, and the handle 406 is fixedly installed on the side wall of the locking block 405. By operating the handle 406, the engagement between the locking block 405 and the locking seat 404 can be released, allowing the locking block 405 and the locking seat 404 to separate, thereby allowing the upper arc-shaped support plate 402 to rotate relative to the lower arc-shaped support plate 401, so as to install the fixing cylinder 5 in the annular bracket 4.

[0024] In this embodiment, preferably, an annular track 6 is fixedly installed in the middle of the inner cavity of the fixed cylinder 5. A slider 7 is slidably installed on the annular track 6, and a telescopic rod 8 is fixedly installed on the slider 7. A positioning plate 9 is fixedly installed at the telescopic end of the telescopic rod 8. A locking knob 701 for locking the slider 7 is provided on the slider 7, and multiple locking knobs 801 for locking the telescopic rod 8 are provided on the telescopic rod 8. The locking knobs 701 and 801 are locked by a threaded fastening structure. Other conventional locking structures can also be used. The locking method of the body is existing technology and will not be described in detail here. Its working principle is as follows: When fixing the fixing cylinder 5 to the steel structure, firstly, according to the cross-sectional shape and size parameters of the steel structure, adjust the telescopic length of the telescopic rod 8 and lock it through the locking knob 801 to ensure that the telescopic rods 8 in multiple fixing cylinders 5 are adjusted to the same length, ensuring the consistency of the clamping reference. During clamping, a flat surface with a large surface area of ​​the steel structure is selected as the positioning reference surface, so that the positioning plate 9 is in close contact with the reference surface to achieve the initial positioning calibration of the steel structure. Then, the final clamping and fixing of the steel structure is completed through multiple fixing components. Ensure that the relative positions of the two sets of fixing cylinders 5 and the corresponding steel structures are completely consistent, providing a reliable guarantee for the precise connection of the two steel structures in the future; each time they are clamped, they are aligned with the positioning plate 9 using the same reference plane. The shape and size of the positioning plate 9 can be flexibly adapted and adjusted according to the specific structure of the steel structure; a level 10 is fixedly installed on the positioning plate 9. After the steel structure is fixed on the annular bracket 4, the horizontal angle of the steel structure can be adjusted by rotating the fixing cylinders 5. During the rotation, by observing the level 10 at the end of the positioning plate 9, the level 10 on both fixing cylinders 5 can be kept in a horizontal state, thus achieving the desired horizontal alignment. The horizontal angles of the two steel structures are now aligned to ensure that the two steel structures to be welded are on the same horizontal line, effectively improving the accuracy of the welding joint and avoiding welding defects caused by joint deviation. Its beneficial effects are as follows: through the cooperation of positioning plate 9 and level 10, the clamping, positioning and angle adjustment of the steel structure are visualized and made more precise, reducing the error of manual adjustment and reducing the time for joint calibration; through the adjustable design of telescopic rod 8 and slider 7, the adaptability of the positioning structure is further improved, ensuring that steel structures of different specifications can be accurately positioned, providing a basic guarantee for the subsequent welding quality.

[0025] In this embodiment, preferably, the fixing component includes a second slider 11, a mounting base 13, an adjusting screw 14, and a fixing block 16. The second slider 11 is slidably mounted on the annular track 502. The mounting base 13 is fixedly connected to the second slider 11. The adjusting screw 14 passes through the mounting base 13 and is threadedly connected to the mounting base 13. The fixing block 16 is rotatably connected to the end of the adjusting screw 14. The second slider 11 is provided with a locking knob 12 for locking the second slider 11. An adjusting knob 15 is fixedly mounted on the end of the adjusting screw 14 away from the fixing block 16. Its working principle is that the second slider 11 can slide freely along the annular track 502 to realize the fixing component. After adjusting the position of slider 11 in the circumferential direction of the fixed cylinder 5, tighten the locking knob 12 to achieve rigid locking of slider 11, thereby fixing the circumferential position of the fixing component. Rotate the adjusting knob 15 to drive the adjusting screw 14 to make threaded feed motion around the mounting base 13. The adjusting screw 14 pushes the fixing block 16 toward the steel structure surface until multiple fixing blocks 16 clamp and fix the steel structure together, realizing the coaxial fixation of the steel structure and the fixed cylinder 5. Its beneficial effect is that the sliding cooperation between slider 11 and the annular track 502 allows the fixing component to adapt to steel structures with different cross-sectional dimensions, further expanding the application range of the device. Moreover, the adjustment operation is convenient and does not require complicated tools.

[0026] In this embodiment, preferably, the upper arc-shaped support plate 402 and the lower arc-shaped support plate 401 are provided with an annular limiting groove 407, and the fixed cylinder 5 is fitted with a limiting ring 501. The limiting ring 501 is rotatably connected to the fixed cylinder 5 through a bearing. When the fixed cylinder 5 is located in the annular bracket 4, the limiting ring 501 is located in the annular limiting groove 407 to limit the fixed cylinder 5, thereby ensuring the stability of the fixed cylinder 5.

[0027] In this embodiment, preferably, the driving assembly includes a guide rail 17, a slide block 18 slidably disposed inside the guide rail 17, a drive screw 19 rotatably mounted inside the guide rail 17, and a motor 20 fixedly mounted on the side wall of the guide rail 17. The sliding support 2 is fixedly mounted on the slide block 18, the guide rail 17 is fixedly mounted on the upper surface of the base 1, the drive screw 19 passes through the slide block 18 and is threadedly connected to the slide block 18, and the output end of the motor 20 is fixedly connected to the end of the drive screw 19. The motor 20 can drive the drive screw 19 to rotate, thereby driving the slide block 18 to move inside the guide rail 17, so as to drive the sliding support 2 to move.

[0028] In this embodiment, preferably, the arc welding wire equipment includes a robotic arm 25 and an arc welding wire machine body 26 mounted on the robotic arm 25. The arc welding wire machine body 26 is equipped with a wire feeding mechanism 27 and an electron gun 28. The wire feeding mechanism 27 is used to continuously supply welding wire, and the electron gun 28 is used to emit an electron beam to melt the welding wire, so that the welding wire is stacked at the joint of the steel structure to form a steel structure node. The robotic arm 25 is equipped with a vision module, which, together with the control module and intelligent algorithm, can realize automatic welding. A guide rail 21 is fixedly installed on the upper surface of the base 1, and a slide block 2 is slidably installed inside the guide rail 21. 24. The robotic arm 25 is fixedly mounted on the slide block 24. A drive screw 22 is rotatably mounted inside the guide rail 21, passing through the slide block 24 and threadedly connected to it. A motor 23 is fixedly mounted at the end of the guide rail 21, and the output end of the motor 23 is fixedly connected to the end of the drive screw 22. Its working principle is as follows: the motor 23 drives the drive screw 22 to rotate, causing the slide block 24 to slide smoothly along the guide rail 21, thereby moving the robotic arm 25 to the preset welding position of the steel structure butt weld. The vision module collects data in real time. The image of the weld location is transmitted to the control module. The control module uses intelligent algorithms to accurately identify and locate the weld position, automatically adjusting the posture of the robotic arm 25 and the welding angle of the electron gun 28 to ensure that the electron gun 28 maintains the optimal welding distance and angle with the weld location. The wire feeding mechanism 27 continuously feeds welding wire to the weld. The electron beam emitted by the electron gun 28 is focused on the joint between the welding wire and the steel structure, melting the welding wire to form a molten pool. After the molten pool cools, it forms the weld, realizing the fusion welding of the steel structure node. During the welding process, the robotic arm 25 can automatically adjust its movement trajectory according to the weld trajectory, cooperating with the steel structure. Synchronous rotation enables automated welding of circumferential or complex trajectory welds. Its advantages include: automation and precision in welding operations through a combination of visual positioning and intelligent control, significantly reducing manual labor intensity and avoiding uneven welding quality issues caused by manual welding; the coordinated arrangement of the robotic arm 25 and slide 24 broadens the welding operation coverage, adapting to welding of steel structure nodes in different locations and of different specifications; compared to traditional welding, arc welding offers better weld formation quality, higher joint strength, and higher wire utilization, effectively improving the load-bearing capacity and service life of steel structure nodes.

[0029] Please see Figure 2 and Figures 6-10In this embodiment of the invention, the second drive assembly includes a first rotating shaft 29, a second rotating shaft 30, a drive wheel 31, a third motor 35, a first gear 33, and a second gear 34. The first rotating shaft 29 passes through the fixed support 3 and is rotatably engaged with the fixed support 3. The second rotating shaft 30 passes through the sliding support 2 and is rotatably engaged with the sliding support 2. One end of the second rotating shaft 30 extends into the interior of the first rotating shaft 29 and is slidably engaged with the first rotating shaft 29. A first gear 33 is fixedly mounted on the first rotating shaft 29. The third motor 35 is fixedly mounted on the upper surface of the base 1, and a second gear 34 is fixedly mounted on the output end of the third motor 35. Gear 2 34 meshes with gear 1 33. Drive wheels 31 are fixedly mounted on both shaft 1 29 and shaft 2 30, and annular transmission airbags 32 are fixedly mounted on both drive wheels 31. The working principle is as follows: when the fixed cylinder 5 is limited within the annular bracket 4, the outer wall of the fixed cylinder 5 and the annular transmission airbag 32 are in a corresponding contact state. When it is necessary to drive the fixed cylinder 5 to rotate, motor 35 is started. The output end of motor 35 drives gear 2 34 to rotate. Gear 2 34 meshes with gear 1 33, driving shaft 1 29 to rotate. Because shaft 2 30 slides with shaft 1 29 through the strip-shaped limiting groove 3001, shaft 2 30 can only move along shaft 1 29. 9. Since the axis of rotation is slidable, it cannot rotate relative to the first rotating shaft 29. Therefore, when the first rotating shaft 29 rotates, it synchronously drives the second rotating shaft 30 to rotate. The first rotating shaft 29 and the second rotating shaft 30 respectively drive the drive wheels 31 on them to rotate. The drive wheels 31 drive the annular transmission airbag 32 to rotate synchronously. The annular transmission airbag 32 drives the two fixed cylinders 5 to rotate synchronously and at the same speed through friction with the outer wall of the fixed cylinder 5, thereby driving the two steel structures to rotate synchronously, achieving uniform switching of welding positions. Its beneficial effects are: using a gear meshing transmission method ensures the transmission accuracy and synchronization of the first rotating shaft 29 and the second rotating shaft 30, avoiding asynchronous rotation of the steel structures due to transmission deviation, thus ensuring the welding joint... The uniformity of the head; the setting of the annular transmission airbag 32 can achieve reliable transmission through friction; the sliding fit design of the first rotating shaft 29 and the second rotating shaft 30 can adapt to the horizontal movement of the sliding frame 2, ensuring that the second driving component can always provide a stable rotational driving force to the fixed cylinder 5 during the movement of the sliding frame 2, without the need for additional adjustment of the transmission structure, thus improving the overall performance and operational stability of the device; the second rotating shaft 30 is provided with a strip-shaped limiting groove 3001, which allows the second rotating shaft 30 to slide only relative to the first rotating shaft 29 and not rotate relative to the first rotating shaft 29, so that the rotation of the first rotating shaft 29 can drive the second rotating shaft 30 to rotate.

[0030] In this embodiment, preferably, the annular transmission airbag 32 has a hollow structure. A piston 39 is slidably disposed inside the rotating shaft 29. The rotating shaft 30 and the piston 39 share an infusion channel 3002. Both drive wheels 31 have infusion pipes 3101 inside. One annular transmission airbag 32 is connected to the inner cavity of the rotating shaft 29 via the infusion pipe 3101, and the other annular transmission airbag 32 is connected to the infusion channel 3002 via the infusion pipe 3101. An infusion channel 2901 is disposed on the side of the rotating shaft 29 away from the rotating shaft 30. An infusion tube 3 is fixedly installed at the end of the rotating shaft 29 away from the rotating shaft 30. 8. Infusion tube 38 is connected to the inner cavity of rotating shaft 29 via infusion channel 2901. A cylinder 36 is fixedly installed on the base 1. A piston 40 is slidably installed inside the cylinder 36. The piston 40 is elastically connected to the inner wall of the cylinder 36 away from the rotating shaft 29 via a spring 41. A cylinder 42 is fixedly installed at the end of the cylinder 36 away from the rotating shaft 29. The output end of the cylinder 42 extends into the cylinder 36 and a pusher 43 is fixedly installed thereon. Infusion tube 37 is connected to the cylinder 36. Infusion tube 37 is connected to infusion tube 38 and is rotatably connected to infusion tube 38. The rotatable connection is sealed. Its working principle is: cylinder 36, infusion tube 38... 38. The infusion tubing 37, rotating shaft 1 29, rotating shaft 2 30, infusion pipe 3101, and annular transmission airbag 32 are all filled with hydraulic oil, forming a closed hydraulic transmission circuit. When cylinder 42 is not under pressure, annular transmission airbag 32 is in a contracted state. At this time, annular transmission airbag 32 is not in contact with the outer wall of fixed cylinder 5. The two fixed cylinders 5 can be manually rotated to easily adjust the angle of the steel structure until both levels 10 are in a horizontal state, completing the angle calibration of the steel structure. After the angle calibration is completed, the output end of control cylinder 42 extends, pushing push block 43 to move towards piston 2 40. After push block 43 contacts piston 2 40, it pushes piston 2 40 to move away from cylinder 42, thus moving the cylinder... The hydraulic oil inside cylinder 36 is squeezed into infusion pipe 2 37. The hydraulic oil then enters the inner cavity of rotating shaft 29 and infusion channel 2 3002 through infusion pipe 1 38, and then enters the two annular transmission airbags 32 through infusion pipe 3101, causing the two annular transmission airbags 32 to expand synchronously until the annular transmission airbags 32 are tightly attached to the outer wall of fixed cylinder 5 and a preset pressure is applied. At this time, starting drive component 2 can drive fixed cylinder 5 to rotate. In the natural state, the annular transmission airbags 32 contract, which makes it easy to manually adjust the angle of the steel structure and reduces the difficulty of angle calibration. The setting of piston 1 39 can effectively seal the inner cavity of rotating shaft 29 to prevent hydraulic oil leakage and ensure the sealing and stability of the hydraulic circuit.The spring 41 allows hydraulic oil to flow adaptively between the components when the second rotating shaft 30 slides alongside the first rotating shaft 29. The spring 41 has low elasticity, preventing excessive expansion of the annular transmission airbag 32 even with high compression. A pressure sensor on the push block 43 detects the pressure between the second piston 40 and the push block 43; higher pressure results in greater expansion of the annular transmission airbag 32, ensuring it expands to an appropriate level.

[0031] This invention also discloses an integrated forming method for steel structure nodes based on electric arc fuses, comprising the following steps: S1. The two steel structures to be welded are lifted by a crane, and then the two fixing cylinders 5 are respectively placed on the two steel structures. The fixing cylinders 5 are fixed to the steel structures by the fixing components to achieve the positioning of the fixing cylinders 5 and the steel structures. S2. Rotate the upper arc-shaped support plate 402 to open the ring bracket 4. Move the steel structure by the crane to move the fixed cylinder 5 to the corresponding limit position of the lower arc-shaped support plate 401. Then reset the upper arc-shaped support plate 402 and lock it by the locking component, so that the fixed cylinder 5 is detachably limited in the ring bracket 4, and the initial clamping of the steel structure is completed. S3. After the two steel structures are fixed in the two ring brackets 4 respectively, adjust the spatial angle of the two steel structures to the preset welding posture, drive the sliding frame 2 to move smoothly toward the fixed frame 3 through the drive component 1, so that the welding end faces of the two steel structures are connected, and then start the arc welding wire equipment to perform the welding wire operation to realize the integrated forming of the steel structure node. S4. During the welding process, the two fixed cylinders 5 are driven to rotate synchronously by the drive component 2, which in turn drives the two steel structures to rotate synchronously in order to switch the welding position.
