Description

Technical Field

[0001] This invention relates to the field of welding technology, and in particular to a welding device for steel cages used in the production of utility poles. Background Technology

[0002] The field of welding technology encompasses core aspects such as joining processes of metal materials, design and manufacturing of welding equipment, research and development of welding auxiliary structures, and adaptation of welding applications to various industries. Overall, it covers research on welding principles, adaptation of welding consumables, welding quality control technologies, and the development and optimization of specialized welding devices, and is widely used in multiple fields such as construction, machinery manufacturing, and power engineering.

[0003] Chinese Patent Publication No. CN118513765B discloses a welding device and method for steel cages used in pole production. The device includes a base plate fixedly installed in a working area, a longitudinal seat plate hinged to one end of the base plate, a winding cylinder rotatably mounted on the base plate, a motor for driving the winding cylinder to rotate mounted on one side of the base plate, a rope connected to and wound on the winding cylinder, and through holes for the rope to pass through at both the upper and lower parts of the longitudinal seat plate. A wheel axle is rotatably mounted within the through holes to conform to the rope and reduce friction through rotation. A connecting frame is connected to the top of the longitudinal seat plate, and a rope limiting plate is connected to the bottom of the connecting frame. This design, through the longitudinal seat plate, ensures the welding function of the steel cage while allowing the welding device to be lifted at multiple angles around the base plate, reducing the required floor space and facilitating equipment transfer and storage, thus helping to reduce production costs. However, this design still has the following drawbacks: The aforementioned literature only uses a simple structure such as a base plate, longitudinal seat plate, winding cylinder and rope limiting plate to achieve basic welding and equipment angle adjustment. It lacks a dedicated clamping mechanism and relies only on rope traction and limiting plate constraint, which cannot achieve adaptive clamping and precise positioning of the reinforcing bars. This can easily lead to the displacement and tilting of the reinforcing bars during welding. In addition, there is no guiding and buffering structure, resulting in insufficient feeding accuracy.

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0019] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 as well as Figure 8As shown, a steel cage welding device for pole production includes a support platform 1. Two Y-shaped support frames 2 are fixedly connected to the upper end of the support platform 1. The two Y-shaped support frames 2 can stably support the welded steel cage, providing reliable bottom support for the entire welding process, ensuring the stability of the steel cage's posture and preventing displacement. A clamping mechanism 3 is fixedly connected to the right side of the support platform 1. The clamping mechanism 3 is used to clamp, release, and transport the steel bars to be welded. A fixing mechanism 4 is fixedly connected to the upper end of the clamping mechanism 3. The fixing mechanism 4 can effectively stabilize the posture of the welding machine 5 and prevent displacement during welding. If a misalignment occurs, a welding machine 5 is fixedly connected to the upper left side of the clamping mechanism 3. The welding machine 5 is responsible for welding the reinforcing cage, cleaning the welding slag, and pulling the welding wire. The clamping mechanism 3 includes a housing 31. A clamping assembly 33 is slidably connected to the upper right side of the housing 31. The clamping assembly 33 is used to directly clamp the reinforcing bar to be welded and move it. Protective tracks 32 are fixedly connected to both sides of the clamping assembly 33. The protective tracks 32 can prevent the welding slag generated during welding from falling and protect the equipment parts from damage. Two connecting posts 35 are fixedly connected to the bottom of the inner cavity of the housing 31. 5. Two symmetrically arranged guide mechanisms 34 are fixedly connected to the upper end. The guide mechanisms 34 can accurately guide the lifting and moving trajectory of the clamping component 33. A bidirectional motor 37 is fixedly connected to the left side of the inner cavity of the outer shell 31. A bidirectional threaded rod 36 is fixedly connected to the right output end of the bidirectional motor 37. The bidirectional threaded rod 36 drives the clamping component 33 to move left and right through threaded transmission. A mating gear 38 is fixedly connected to the left output end of the bidirectional motor 37. The mating gear 38 assists in transmitting power to ensure the coordinated operation of the equipment. The guide mechanism 34 includes a guide plate 341. The guide rod 3335 has a groove inside its 341. The groove provides a movement trajectory for the guide rod 3335 to achieve guidance. A toggle block 342 is rotatably connected inside the groove. The toggle block 342 can control the movement path of the guide rod 3335 to avoid mistraveling. A connecting plate 343 is fixedly connected to the bottom of the toggle block 342. The connecting plate 343 is used to connect the toggle block 342 and the spring 344 to transmit force. A spring 344 is fixedly connected to one side of the connecting plate 343. The spring 344 uses its own elasticity to drive the toggle block 342 to reset, ensuring that the guide rod 3335 can stably enter the bottom guide groove.

[0020] The clamping assembly 33 includes a sliding frame 331, which is the overall frame of the clamping assembly 33. A tensioning mechanism 332 is fixedly connected to the upper end of the sliding frame 331. The tensioning mechanism 332 is hydraulically driven to clamp and release the steel bars, directly acting on the clamping of the steel bars. A hydraulic mechanism 333 is fixedly connected to the bottom of the sliding frame 331. The hydraulic mechanism 333 provides power support for the tensioning mechanism 332 and drives the tensioning mechanism 332 to move through the flow of liquid. Two connecting frames 334 are fixedly connected to the bottom of the hydraulic mechanism 333. The two connecting frames 334 play an auxiliary fixing role, enhancing the stability of the connection between the hydraulic mechanism 333 and the sliding frame 331 and preventing it from falling off during operation. The upper parts of the two connecting frames 334 are fixedly connected to the bottom of the sliding frame 331, further improving the structural stability. A telescopic mechanism 335 is fixedly connected to the inner cavity of the hydraulic mechanism 333. The telescopic mechanism 335 can cooperate with the upward movement of the guide rod 3335 to drive the clamping assembly 52 of the welding machine 5 to achieve auxiliary clamping and positioning of the steel bars for subsequent transportation. The hydraulic mechanism 333 includes a hydraulic chamber 3331, which stores hydraulic fluid and provides space for fluid flow. A sliding plate 3332 is slidably connected to the inner cavity of the hydraulic chamber 3331. The sliding plate 3332 can slide up and down to compress the fluid under the action of the connecting rod 3333. Two connecting rods 3333 are fixedly connected to the bottom of the sliding plate 3332. The connecting rods 3333 transmit the tension of the guide rod 3335 to drive the sliding plate 3332, thus realizing the transmission and conversion of force. A second spring 3334 is wound around the outer surface of the two connecting rods 3333. The second spring 3334 can generate elastic tension to drive the guide rod 3335 upwards. To buffer the movement and prevent excessive force, guide rods 3335 are fixedly connected to the bottom of both springs 3334. Guide rods 3335 move under the guidance of the groove in the guide plate 341 and are key components that drive the hydraulic mechanism 333. The bottom of the front guide rod 3335 is fixedly connected to the upper part of the telescopic mechanism 335, realizing the linkage between the guide rod 3335 and the telescopic mechanism 335. Two guide pipes 3336 are fixedly connected to the upper part of the hydraulic chamber 3331. The guide pipes 3336 provide flow channels for the hydraulic fluid, so that the fluid in the hydraulic chamber 3331 can flow smoothly into the reservoir 3322 to drive the tensioning mechanism 332. Example 2 further achieves the purpose of clamping the reinforcing cage based on Example 1. For further details, please refer to [link to example]. Figure 4 and Figure 8As shown, the telescopic mechanism 335 includes a telescopic rod 3351. A telescopic rod 3352 is slidably connected to the left side of the telescopic rod 3351. The telescopic rod 3352 can slide along the telescopic rod 3351 to adjust its length and adapt to different stroke requirements. A mating rod 3353 is slidably connected to the left side of the telescopic rod 3352. The mating rod 3353 can mesh with the gear plate 523 to transmit power. The upper part of the mating rod 3353 is mated with the welding machine 5. Specifically, it is mated with the gear plate 523 of the welding machine 5 to drive the rotating fixed plate 522 to rotate, thereby achieving auxiliary clamping and positioning of the steel bar and ensuring that the steel bar is stable in posture during the conveying process, which is convenient for the clamping mechanism 3 to convey it again. The tensioning mechanism 332 includes a second outer shell 3321. The bottom of the second outer shell 3321 is fixedly connected to the upper part of the sliding frame 331 to ensure that the tensioning mechanism 332 can move synchronously with the sliding frame 331. A liquid storage shell 3322 is fixedly connected to the inner cavity of the second outer shell 3321. The liquid storage shell 3322 is used to receive the hydraulic fluid flowing in from the guide pipe 3336 and distribute it to each guide hole 3323. Several guide holes 3323 are opened inside the liquid storage shell 3322. The guide holes 3323 provide a flow channel for the hydraulic fluid, so that the fluid can act evenly on each sliding rod 3324. Sliding rods 332 are slidably connected to the inner cavities of the several guide holes 3323. 4. The sliding rod 3324 moves the clamping block 3326 under the push of the hydraulic fluid, realizing the tightening and loosening action. The clamping block 3326 is fixedly connected to the side of the sliding rod 3324 that is far apart from each other. The clamping block 3326 directly contacts the steel bar to achieve clamping and fixing. Its structural design can fit the surface of the steel bar to improve the clamping stability. The clamping block 3325 is fixedly connected to the side of the clamping block 3326 that is close to each other. The spring 3325 can drive the clamping block 3326 to reset when the hydraulic fluid flows back, realizing the loosening action of the steel bar. At the same time, it plays a buffering role to avoid damage caused by the rigid contact between the clamping block 3326 and the steel bar. Example 3: This example, based on Examples 1 and 2, achieves the purpose of roll welding of the reinforcing cage. For further details, please refer to... Figure 3 , Figure 9 and Figure 10 As shown, the fixing mechanism 4 includes two counterweight plates 41. The counterweight plates 41 can increase the weight of the upper part of the device to improve the overall stability and prevent the equipment from tipping over during welding. Connecting wheels 42 are fixedly connected to the left side of each of the two counterweight plates 41. The connecting wheels 42 can fit against the surface of the roller welding machine 5 to help stabilize the posture of the roller welding machine 5. The outer surfaces of the two connecting wheels 42 are in conjunction with the roller welding machine 5. Through linkage with the roller welding machine 5, the stability of the equipment during operation is further improved. Two fixing blocks 43 are slidably connected to the bottom of the outer surface of the roller welding machine 5. The fixing blocks 43 can cooperate with the rotating component 54 to form a stable welding platform to ensure the stability of the rotating component 54 during welding. The right sides of the two fixing blocks 43 are fixedly connected to the adjacent counterweight plates 41 to realize the stable connection between the fixing mechanism 4 and the roller welding machine 5. The roll welding machine 5 includes a fixed frame 51, a second clamping component 52, an electromagnetic block 53, a rotating component 54, and other components to ensure the precise positioning of each component. The second clamping component 52 is fixedly connected to the upper end of the fixed frame 51. The second clamping component 52 is used to assist in clamping the steel bars and cooperate with the clamping mechanism 3 to achieve stable conveying of the steel bars. The electromagnetic block 53 is fixedly connected to the left side of the second clamping component 52. The electromagnetic block 53 can generate magnetic force to assist in fixing the steel bars and improve clamping stability. The rotating component 54 is slidably connected to the side of the two fixed blocks 43 that are close to each other. The rotating component 54 is responsible for driving the welding ring 545 to rotate and completing welding, slag removal, and other operations. It is the core working component of the roll welding machine 5. The clamping assembly 2 52 includes a fixing plate 1 521. The bottom end of the fixing plate 1 521 is fixedly connected to the upper part of the fixing frame 51, so as to realize the stable connection between the clamping assembly 2 52 and the welding machine 5. The inner cavity of the fixing plate 1 521 is rotatably connected to a rotating fixing disk 522. The rotating fixing disk 522 can rotate under the drive of the toothed disk 523 to clamp and position the steel bar, preventing the steel bar from shifting during welding and transportation. The toothed disk 523 is fixedly connected to the left side of the rotating fixing disk 522. The toothed disk 523 transmits power through meshing with the mating rod 3353, converting the action of the telescopic mechanism 335 into the rotation action of the rotating fixing disk 522. The outer surface of the toothed disk 523 cooperates with the mating rod 3353 to realize the linkage between the clamping mechanism 3 and the welding machine 5, ensuring the continuity of operation. Rotating assembly 54 includes a rotating disk 541, which is the core rotating component of the rotating assembly 54, driving components such as the welding ring 545 and welding mechanism 546 to rotate synchronously. A fixing plate 542 is fixedly connected to the bottom left side of the rotating disk 541. The fixing plate 542 provides installation support for the U-shaped slag-removing head 543, ensuring the stability of the slag-removing structure. The U-shaped slag-removing head 543 is slidably connected to the surface of the fixing plate 542. The U-shaped slag-removing head 543 can remove slag from the weld after welding, improving the weld quality. In terms of quality, a spring 544 is wound around the outer surface of the U-shaped slag-removing head 543. The spring 544 can realize the elastic buffering and reset of the U-shaped slag-removing head 543, so that the slag-removing action is gentle and can continuously act on the weld. A welding ring 545 is rotatably connected to the middle of the left side of the rotating disk 541. The welding ring 545 is used to carry the welding wire and provide consumables for welding. A welding mechanism 546 is fixedly connected to the upper left side of the rotating disk 541. The welding mechanism 546 is responsible for completing the specific rolling welding action and is a key structure for realizing steel bar welding. The welding mechanism 546 includes a fixed plate 3 5461. The right side of the fixed plate 3 5461 is fixedly connected to the rotating disk 541 to ensure that the welding mechanism 546 can rotate synchronously with the rotating disk 541. Two sliding rods 2 5463 are fixedly connected to the bottom of the fixed plate 3 5461. The two sliding rods 2 5463 guide the moving block 5465 to ensure its accurate vertical movement trajectory. The bottom of the two sliding rods 2 5463 is fixedly connected to a fixed block 2 5464, which further strengthens the installation stability of the sliding rods 2 5463. The fixed block 2 5464 is fixedly connected to the rotating disk 541 to improve the overall stability of the welding mechanism 546. A bolt 5462 is rotatably connected to the middle of the fixed plate 3 5461. The bolt 5462 provides power through threaded transmission to drive the moving block 5465 to move up and down. The moving block 5465 is threadedly connected to the outer surface of the bolt 5462. The moving block 5465 is used to drive... The height of the sliding rod 5466 and the welding wheel 5467 is adjusted. The sliding rod 5466 is slidably connected to the inner cavity of the moving block 5465. The sliding rod 5466 provides installation support for the welding wheel 5467 and transmits power to the moving block 5465. The bottom of the moving block 5465 is fixedly connected to the spring 5469. The spring 5469 can provide a buffer rebound effect for the welding wheel 5467, avoiding damage caused by rigid contact between the welding wheel 5467 and the welding ring 545, while ensuring stable welding pressure. The bottom of the sliding rod 5466 is rotatably connected to the welding wheel 5467. The welding wheel 5467 is in close contact with the welding wire on the welding ring 545. The welding of the steel bar is completed by the rolling action. Two traction wheels 5468 are set on the left side of the rotating disk 541. The two traction wheels 5468 can stably pull the welding wire in the welding ring 545, avoiding the welding wire from tangling or slipping, ensuring stable welding wire delivery during the welding process, and ensuring uniform welding quality.

[0021] It should be noted that the welding structure in this scheme adopts the principle of the roller welding machine 5. The principle is that between two rotating conductive roller electrodes, the roller electrodes are connected to the welding current and a certain pressure is applied. When the workpiece is continuously fed in as the roller electrodes rotate, the current generates concentrated Joule heat through the contact resistance at the workpiece overlap, which rapidly heats the metal in that area to a plastic or locally molten state. At the same time, under the continuous pressure of the rollers, the plastic metal undergoes tight bonding and crystallization, ultimately forming a continuous and dense weld, thus achieving continuous welding of the workpiece.

[0022] Working Principle: This solution uses two Y-shaped support frames 2 on the upper end of the support platform 1 to support the welded rebar cage, ensuring positional stability during the welding process. The clamping mechanism 3, located on the right side of the support platform, securely clamps the rebar cage to be processed. The fixing mechanism 4 above it, through two counterweight plates 41 and connecting wheels 42, works with the welding machine 5 to stabilize the equipment's posture and prevent welding deviation. The clamping mechanism 3 includes a housing 31 and a clamping assembly 33 slidably connected to the upper right end. Protective tracks 32 are provided on both sides of the clamping assembly to enhance operational safety and prevent weld slag from falling onto the rebar. The inner cavity of structure 3 is equipped with two connecting columns 35 and symmetrically arranged guide mechanisms 34. The guide plate 341 engages with the guide rod 3335 via a groove on its inner surface, guiding the guide rod 3335 to rise or fall. When the guide rod 3335 needs to rise, a spring 3334 wound around its outer surface pulls it upward, causing the two connecting rods 3333 to rise as well. During the ascent of the two connecting rods 3333, the sliding plate 3332 fixedly connected to their upper ends pushes the internal liquid, causing... The liquid in the hydraulic chamber 3331 enters the inner cavity of the liquid storage shell 3322 through two guide pipes 3336, and then flows into several guide holes 3323, causing the clamping blocks 3326 to move away from each other, thereby fixing the steel bars to be welded. Further, the bidirectional motor 37 starts at this time. During the start-up process of the bidirectional motor 37, it drives the bidirectional threaded rods 36 fixedly connected to the left and right sides and the mating gear 38 to rotate. During the rotation of the bidirectional threaded rods 36, the clamping assembly 33 moves to the left, thereby clamping the assembly... The clamping assembly 33 can slowly move several steel bars that need to be welded to the left. After the clamping assembly 33 moves to the fixed position, it will move to the right under the thread of the bidirectional threaded rod 36. During the movement to the right, the guide rod 3335 will rise rapidly under the action of the spring 3334 and move to the upper part of the guide plate 341. Then, the steel bars will be released under the guide groove on the upper part of the guide plate 341 and moved to the far right. After moving to the bottom guide groove, the steel bars that need to be welded will be fixed and the cycle will repeat. It should be noted that when the connecting rod 3333 moves through the upper guide groove of the guide plate 341, the clamping component 33 will release the clamping of several steel bars that need to be welded. When the connecting rod 3333 moves through the lower guide groove of the guide plate 341, it will clamp several steel bars that need to be welded. When the guide rod 3335 passes through the actuating block 342, the actuating block 342 will deform, causing the actuating block 342 to rotate and compress the spring 344 through the connecting plate 343. After the guide rod 3335 enters the bottom guide groove, the spring 344 itself will have its own elasticity, which will cause the actuating block 342 to reset and prevent the guide rod 3335 from moving through the upper guide groove. Furthermore, during the upward movement of the guide rod 3335, since the bottom of one of the springs 3334 is fixedly connected to the telescopic mechanism 335, the upper part of the cooperating rod 3353 will cooperate with the gear plate 523 during the upward movement of the spring 3334. During the rotation of the gear plate 523, the rotating fixed plate 522 will be driven to rotate and clamp the steel bar to be welded, thereby facilitating the clamping mechanism 3 to transport the steel bar again. Further rotating component 54 drives welding ring 545 to rotate via rotating disk 541, while welding mechanism 546 on the left side completes the welding operation. Fixed plate 3 5461 connects sliding rod 2 5463 and fixed block 2 5464 to provide structural support. Rotary bolt 5462 moves sliding rod 3 5466 downward via moving block 5465 for adjustment. Subsequently, welding wheel 5467 makes close contact with welding wire on welding ring 545 to complete the roll welding action. Spring 5 5469 at the bottom provides buffer rebound. Two traction wheels 5468 on the left side of rotating disk 541 can stably pull welding ring. The 545 inner welding line prevents tangling and slippage. In addition, the fixed block 43 and the rotating component 54 cooperate to form a stable welding platform. The U-shaped slag knocking head 543 realizes the slag knocking function after welding through the spring 544, effectively cleaning the weld and improving the welding quality. Through the linkage of the above-mentioned multiple sets of clamping, guiding, telescopic, welding, slag knocking and traction structures, not only can the precise positioning and stable clamping of the steel cage be realized, but also continuous and efficient welding operations can be achieved, ensuring stable welding quality. The device as a whole has excellent effects such as compact structure, safe operation, high degree of automation, flexible adjustment, uniform welding and convenient maintenance.
