Technical Field
[0001] This application relates to the field of steel mesh welding equipment technology, and more specifically, to a steel bar welding positioning device for the production and processing of threaded steel mesh. Background Technology
[0002] Rebar mesh, also known as welded rebar mesh, is a type of reinforcing mesh made of steel bars. It consists of longitudinal and transverse reinforcing bars arranged at regular intervals and perpendicular to each other, with all intersections welded together. The application of rebar mesh improves the quality of reinforced concrete projects because it provides more uniform force distribution and better structural stability. This mesh is made of steel bars of different diameters, typically between 4 and 14 mm, which are welded together to form a strong grid structure. Therefore, rebar mesh is mainly produced using... The production and processing effect is achieved by positioning and welding the steel bars in both directions. For example, the patent document with the prior art publication number CN211219405U provides a steel bar mesh positioning and welding device. This device uses a sliding groove, steel bar fixing parts and a plate to form a positioning mechanism. Multiple sets of steel bar fixing parts are set in the sliding groove. In use, the required number of steel bar fixing parts can be installed according to the needs, and the distance between each steel bar fixing part can be adjusted according to the size of the mesh in the steel bar mesh. This positioning mechanism is flexible and easy to adjust according to actual needs. Furthermore, the steel bars after positioning are welded by multiple sets of welding guns at the bottom of the working chamber.
[0003] Although the existing technical solutions mentioned above can achieve the effect of positioning and welding steel bars by using adjustable steel bar fixing parts in conjunction with welding guns, multiple sets of welding guns are usually fixed. For steel bar meshes with different intervals, the welding points of the welding guns need to be further adjusted, making it difficult to automatically weld steel bar welding points with different positioning intervals, resulting in poor flexibility of use.
[0004] In view of this, we propose a rebar welding positioning device for the production and processing of rebar mesh. Summary of the Invention

[0048] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:
[0049] (1) This application uses a transverse positioning mechanism to move and position the reinforcing bars so as to arrange the reinforcing bars evenly. While arranging the reinforcing bars, the transverse positioning mechanism can move the welding mechanism along the square bar so as to position the welding mechanism synchronously. This allows the welding mechanism to be moved and used according to different specifications of steel mesh, making it more flexible to use.

[0052] (4) This application sets up a motor A to drive the chain B to run, so that the chain B drives the positioning seat A to automatically arrange the steel bars, replacing the traditional manual arrangement, reducing the workload. In addition, according to the control program of the motor A, the motor A can drive the translation component to run independently, so that the translation component can drive the welding gun to be above each positioning point according to the preset control program, so that the welding gun can be positioned in the welding direction of each steel bar.

[0070] The present application will be further described in detail below with reference to the accompanying drawings.
[0071] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 This application discloses a rebar welding positioning device for the production and processing of rebar mesh, including a base 1. Square rods 11 are symmetrically arranged on the top of the base 1. A welding mechanism 2 is slidably arranged on the outer side of the square rods 11. The welding mechanism 2 includes a bearing plate 21 slidably arranged on the outer side of the square rods 11. A welding torch 22 movable in both longitudinal and vertical directions is arranged on the outer side of the bearing plate 21. Side plates 12 are arranged on both sides of the top of the base 1. A longitudinal positioning mechanism 3 is arranged on the outer side of the side plates 12. The longitudinal positioning mechanism 3 includes two sets of fixed... The positioning seat A31 of the slot is provided. Two sets of positioning seats A31 are respectively set on the outside of the side plate 12. The top of the base 1 is also provided with a transverse positioning mechanism 4. The transverse positioning mechanism 4 includes two liftable supports 41. A chain C42 is provided on the side of the supports 41 that is close to each other. Positioning seats B43 for transverse conveying and positioning of steel bars are evenly distributed on the outer periphery of the chain C42. The positioning seat B43 has a positioning groove on its inner side. Under the drive of the chain C42, the positioning seat B43 synchronously drives the welding torch 22 to move laterally for positioning when conveying steel bars.
[0072] When arranging transverse reinforcement, the threaded reinforcement is longitudinally positioned using positioning seats A31 evenly distributed on the outer side of the side plate 12 to ensure the accuracy of the lower layer reinforcement arrangement. Then, the longitudinal reinforcement is placed in the positioning groove inside the positioning seat B43. Driven by the chain C42, the positioning seat B43 moves a specified distance to move the reinforcement carried by the positioning seat B43 to the welding position. At this time, the positioning seat B43 drives the bearing plate 21 to slide horizontally along the square rod 11, positioning the welding torch 22 diagonally above the welding point. Then, under the lowering action of the support 41, the reinforcement is placed on top of the lower layer reinforcement. At this time, the upper layer reinforcement is positioned at the welding position by the positioning seat B43. Finally, the welding is performed by the welding torch 22. The welding torch 22 tilts downwards and extends, bringing the welding end closer to the welding point between two vertically intersecting reinforcing bars to achieve the welding effect. Under the action of the longitudinal movement of the welding torch 22, the welding torch 22 can weld each longitudinal reinforcing bar. Then, under the action of the transverse positioning mechanism 4, the welding torch 22 can be automatically positioned in the transverse direction, so that the welding torch 22 can adapt to the welding work of steel mesh of different specifications. After welding, the support 41 continues to descend, so that the positioning seat B43 is disengaged from the reinforcing bar to ensure the continuous operation of the chain C42. The positioning grooves on the inner side of the positioning seat A31 and the positioning seat B43 are both V-shaped grooves, which can adapt to threaded reinforcing bars of different diameters. There are two welding torches 22 symmetrically arranged, located on both sides of the reinforcing bar, for welding the welding points on both sides at the same time.
[0073] To ensure that the positioning seat B43 does not affect the continuous operation of the chain C42 after detaching from the reinforcing bar, refer to Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 9 The lateral positioning mechanism 4 also includes two sets of sprockets E46 for driving the chain C42. The two sets of sprockets E46 are rotatably mounted on the outside of the support 41, and the corresponding two sprockets E46 in the two sets are linked by a connecting shaft 47. One sprocket E46 is driven by a motor B44, which is fixedly mounted on the outside of the support 41. The bottom of each support 41 is provided with a hydraulic push rod B45 for providing lifting power. The hydraulic push rods B45 are fixedly mounted on the top of the base 1. The outside of each support 41 is fixedly provided with a support plate 48 for supporting the top positioning seat B43. The support plate 48 is located within the inner circumference of the chain C42. The positioning seat B43 is rotatably mounted on the outside of the chain C42 for rotating to one side to get away from the obstruction of the upper steel bar.
[0074] When conveying longitudinal reinforcing bars through the transverse positioning mechanism 4, the motor B44 drives one of the sprockets E46 to rotate, causing the two sets of sprockets E46 to drive the two chains C42 respectively, realizing the conveying function of the positioning seat B43. At this time, the positioning seat B43 lifts the reinforcing bar and moves it forward. When the reinforcing bar is placed on top of the lower transverse reinforcing bar and the positioning seat B43 descends and disengages from the end of the reinforcing bar, the positioning seat B43 is rotated to move the lifting part away from the end of the reinforcing bar. At this time, when the positioning seat B43 is driven by the support 41 to reset upward again, it will not contact the end of the reinforcing bar, thus preventing the reinforcing bar from affecting the lifting and lowering of the support 41 and the positioning seat B43 after welding. This allows the positioning seat B43 to repeatedly lift and lower to move and position multiple reinforcing bars forward in sequence. The control ends of the motor B44 and the hydraulic push rod B45 are electrically connected to the display controller 17 on the outside of the base 1, and are used to control the automatic operation of the motor B44 and the hydraulic push rod B45 according to the program input to the display controller 17.
[0075] In the above technical solution, in order to enable the supporting part of the positioning seat B43 to rotate away from the end of the reinforcing bar, refer to... Figure 2 , Figure 7 , Figure 8 and Figure 9 The positioning seat B43 includes a U-shaped part 431 fixedly installed on the outside of the chain C42. A bushing 432 is fixedly provided on one side of the end of the U-shaped part 431. A pin 433 is rotatably provided inside the bushing 432. A rotating block 434 is fixedly provided outside the pin 433. A support block 435 serving as a lifting part is fixedly provided outside the rotating block 434. A positioning groove is provided inside the support block 435. One end of the rotating block 434 is fixedly connected to the pin 433, and the other end can be rotated to below the end of the steel bar through the pin 433 to support the steel bar. A limiting platform 438 for horizontally supporting the rotating block 434 is fixedly provided outside the bushing 432.
[0076] When the positioning seat B43 receives the reinforcing bar, the rotating block 434 is in a horizontal state under the support of the limiting platform 438. At this time, the positioning groove opening on the inner side of the support block 435 faces upward, so that the end of the reinforcing bar can be placed inside the support block 435 for positioning. After the reinforcing bar is welded, the positioning seat B43 moves down as a whole and separates from the end of the reinforcing bar through the support 41. At this time, the rotating block 434 can be rotated to move the support block 435 away from the end of the reinforcing bar, so that the positioning seat B43 as a whole does not contact the end of the reinforcing bar in the vertical direction, so as to ensure that the positioning seat B43 can be repeatedly raised and lowered under the action of the support 41.
[0077] Furthermore, to facilitate the rotation of the positioning seat B43 away from the end of the reinforcing bar and simplify the operation process, refer to... Figure 2 , Figure 7 , Figure 8 and Figure 9The positioning seat B43 also includes an extension plate 436 fixed to the outside of the support block 435. One side of the extension plate 436 rotates to the top of the U-shaped part 431 under the drive of the support block 435. At this time, the extension end of the extension plate 436 rotates to the side of the U-shaped part 431 away from the end of the reinforcing bar. A counterweight block 437 is fixedly installed at the extension end of the extension plate 436. A limiting plate 49 for limiting the support block 435 is fixedly installed on the outside of the support 41.
[0078] Under the action of the extension plate 436, after the support block 435 moves down and disengages from the end of the reinforcing bar, the counterweight 437 presses down on the extension end of the extension plate 436, causing the extension plate 436 to drive the support block 435 to rotate away from the end of the reinforcing bar, and rotate from a horizontal state to a vertical state, thus achieving the effect of the support block 435 automatically rotating and disengaging from the reinforcing bar. As the chain C42 conveys the load, when the positioning seat B43 moves to the bottom of the chain C42, the counterweight 437 causes the support block 435 to automatically rotate and reset. At this time, the support block 435 drives the rotation... The moving block 434 is close to the outside of the limiting platform 438. When the support block 435 moves back to the top of the chain C42, the supporting block 435 receiving the steel bar is in an upward-facing state under the action of the limiting plate 49. After the support block 435 drives the steel bar away from the limiting plate 49, it is always kept in a supported state due to the pressure of the steel bar. In this way, each support block 435 can automatically detach from the end of the steel bar after the steel bar is welded, and automatically reset with the drive of the chain C42. There is no need to rotate the support block 435 separately, making the operation more convenient.
[0079] Based on the above scheme, in order to achieve synchronous movement and positioning of the positioning seat B43 and the reinforcing bar and welding torch 22, refer to Figure 2 , Figure 3 , Figure 6 and Figure 7 The welding mechanism 2 also includes a push plate 26 symmetrically fixedly installed at the bottom of the support plate 21. A reinforcing plate 27 is fixedly provided on the outside of the support plate 21 and the push plate 26. The reinforcing plate 27 is located on the side of the push plate 26 away from the positioning seat B43, and the push plate 26 is located on the outside of the support block 435, while not in contact with the U-shaped part 431 and the limiting table 438.
[0080] When the support block 435 carries and transports the steel bar under the pressure of the steel bar, the support block 435 will contact the push plate 26 and push it forward, so that the support block 435 simultaneously drives the push plate 26 and the steel bar to the welding position. At this time, the push plate 26 drives the welding gun 22 to be above the welding position through the bearing plate 21. When the support block 435 completes the positioning and separates from the steel bar, it also separates from the push plate 26, so that the push plate 26 cannot move temporarily. When the next support block 435 drives the steel bar to the next positioning point, it drives the push plate 26 to move to the next positioning point again. This process is repeated. Each positioning of a steel bar can automatically position the welding gun 22 laterally, making it convenient for the welding gun 22 to be positioned before welding.
[0081] To facilitate the positioning of the horizontally arranged reinforcing bars in the lower layer, refer to Figure 1 , Figure 4 and Figure 5 The longitudinal positioning mechanism 3 also includes two chains B32, with positioning seats A31 evenly distributed on the outer periphery of the two chains B32. Each chain B32 is driven by sprockets B33 and C34 respectively. The two sets of sprockets B33 and C34 are rotatably mounted on the outer side of the two side plates 12 respectively. A motor A37 is fixedly installed on the outer side of one of the side plates 12. The motor A37 is linked with one of the sprockets B33. The two sprockets C34 are linked by a spindle 36, which is located between the two side plates 12. The motor A37 is electrically connected to the display controller 17 on the outer side of the base 1.
[0082] When arranging the lower layer of reinforcing bars, the reinforcing bars can be loaded at the designated position without moving them to different positioning seats A31. After receiving the reinforcing bars, the positioning seat A31 at the loading position can move forward a certain distance under the drive of the chain B32. At this time, the distance that the chain B32 drives the positioning seat A31 to move is controlled by the motor A37, which is controlled by the display controller 17. Therefore, according to the required spacing of the reinforcing bars, the motor A37 can be controlled to work automatically by inputting a program into the display controller 17, so that the positioning seat A31 can carry the reinforcing bars for automatic positioning.
[0083] In order to enable the longitudinal positioning mechanism 3 to adapt to the positioning of steel bars of different lengths, one side plate 12 is slidably mounted on the top of the base 1 via a slide rail 13. A hydraulic push rod A14 for driving the side plate 12 to slide is fixedly mounted on the top of the base 1. The side plate 12 is slidably mounted on the outside of the flower shaft 36. The two ends of the flower shaft 36 are rotatably mounted to the base 1 and the other side plate 12, respectively. A sprocket D35 is rotatably mounted on the outside of both side plates 12. One sprocket D35 is coaxially fixedly mounted with the other sprocket D35. The other sprocket D35 slides along the axial direction of the flower shaft 36 under the drive of the side plate 12. The two sprockets D35 are linked with the corresponding sprocket C34. When the motor A37 is running, it can drive the two chains B32 to run synchronously. At the same time, when the hydraulic push rod A14 drives the side plate 12 to drive the longitudinal positioning mechanism 3 to adjust the support length, the side plate 12 drives the corresponding sprocket D35 to slide along the flower shaft 36, so that the linkage between the two chains B32 can always be maintained.
[0084] To facilitate positioning of the welding torch 22 during longitudinal welding, refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 Both square rods 11 are rotatably connected to the top bracket of the base 1. A pulley A16 is fixedly installed on the outside of one of the square rods 11. A rod sleeve 23 is slidably installed on the outside of both square rods 11 along the axial direction. The rod sleeve 23 is rotatably installed on the inside of the bearing plate 21. A gear A24 is coaxially fixed on the outside of one of the rod sleeves 23. The gear A24 is linked with the translation component 25 on the outside of the bearing plate 21.
[0085] Motor A37 is fixedly mounted on the outside of side plate 12 via mounting base 15. Sprocket B33 is movably mounted on the outside of the drive end of motor A37 via a one-way bearing, and pulley B38 is coaxially fixed on the outside of the drive end of motor A37. Pulleys B38 are linked together via pulley A16.
[0086] When the drive end of motor A37 drives sprocket B33 to rotate via a one-way bearing, the drive end of motor A37 synchronously drives pulley B38 to rotate, causing pulley B38 to drive pulley A16 to rotate. Pulley A16 drives translation component 25 through square rod 11 and gear A24, causing translation component 25 to drive welding torch 22 to move horizontally back and forth. At this time, the movement of welding torch 22 does not affect the positioning work of longitudinal positioning mechanism 3 on the reinforcing bars. After the lower layer of reinforcing bars is positioned and arranged, motor A37 is controlled to run in reverse by display controller 17, causing the drive end of motor A37 to drive the inner ring of the one-way bearing to reverse, thus preventing sprocket B33 from rotating and keeping the positioned reinforcing bars stable. At this time, motor A37 drives pulley B38 to reverse, causing pulley A16 to drive translation component 25 to run in reverse, thus causing translation component 25 to drive welding torch 22 to move longitudinally. Motor A37 automatically controls the start and stop of welding torch 22 according to the program input to display controller 17.
[0087] After the welding torch 22 is positioned laterally, in order to enable the translation component 25 to drive the welding torch 22 for positioning and welding, refer to Figure 1 , Figure 3 , Figure 6 and Figure 7 The welding mechanism 2 also includes a translation component 25 disposed on the outside of the support plate 21. The translation component 25 includes two sprockets A251 that rotate on the outside of the support plate 21. A gear B253 is coaxially fixedly connected to the outside of one of the sprockets A251. The gear B253 meshes with the gear A24. The two sprockets A251 are linked by a chain A252. A sliding pin 254 is fixedly disposed on the outside of the chain A252. The sliding pin 254 is slidably disposed on the inside of the slider 255. A vertical sliding hole is opened on the inside of the slider 255. The slider 255 is slidably mounted on the outside of the sliding rod 258. The sliding rod 258 is fixedly fixed to the outside of the support plate 21 parallel to the chain A252. An electric push rod 256 is fixedly disposed at the bottom of the slider 255. A welding torch 22 is mounted on the telescopic end of the electric push rod 256 through a connector 257.
[0088] During longitudinal welding, based on the lateral positioning of the push plate 26, the chain A252 drives the sliding pin 254 to move horizontally, causing the sliding pin 254 to push the slider 255 to move longitudinally along the slide bar 258, thereby driving the welding torch 22 to move longitudinally. Each time it moves above a welding point, the electric push rod 256 pushes the welding torch 22 closer to the welding point by a certain distance. Finally, the welding end of the welding torch 22 tilts downward and extends closer to the welding point, enabling the welding torch 22 to perform longitudinal welding. At this time, the operation of the translation component 25 is controlled by the motor A37, which runs in reverse according to the positioning program input by the display controller 17. There is no need to separately control the positioning of the welding torch 22, making the longitudinal movement and positioning of the welding torch 22 more convenient. The welding torch 22 can adjust the tilt angle on the outside of the connector 257 to adapt to welding work of steel bars of different thicknesses.
[0089] To facilitate the feeding of reinforcing bars into the longitudinal positioning mechanism 3 and the transverse positioning mechanism 4, refer to... Figure 1 , Figure 2 , Figure 10 and Figure 11It also includes a feeding mechanism 5, which is located on the outside of the base 1. The feeding mechanism 5 includes a base plate 51 and a hydraulic support 52 located on the top of the base plate 51. A hydraulic support arm 53 is fixedly installed on the top of the hydraulic support arm 52. A positioning plate 55 is fixedly installed at the bottom of the telescopic end of the hydraulic support arm 53 through an end seat 54. The positioning plate 55 matches the inner side of the positioning groove. A mechanical claw A56 is provided on the outer side of the telescopic end of the hydraulic support arm 53 near the positioning plate 55. A mechanical claw B57 is provided on the outer shell of the hydraulic support arm 53. A straightening mechanism 58 is provided at the bottom of the hydraulic support arm 53. A cutting blade 59 is provided on the outer side of the hydraulic support arm 53. A hydraulic push rod C510 for driving the cutting blade 59 to move is fixedly installed on the top of the hydraulic support arm 53.
[0090] During loading, the straightening mechanism 58 at the bottom of the hydraulic support arm 53 straightens the reinforcing bar. When the end of the reinforcing bar reaches the outside of the positioning plate 55, the mechanical claws A56 and B57 close to support the bottom of the reinforcing bar, and the positioning plate 55 is pushed forward by the telescopic end of the hydraulic support arm 53. At the same time, the straightening mechanism 58 conveys the straightened reinforcing bar forward, allowing the reinforcing bar to move forward while being straightened. After the positioning plate 55 moves forward a certain distance and aligns with the positioning groove directly below, the cutting blade 59 is pushed by the hydraulic push rod C510 to cut the reinforcing bar. The straightening mechanism 58 clamps the reinforcing bars, ensuring stable cutting. Finally, under the action of the hydraulic support 52, the hydraulic arm 53 moves the reinforcing bars downward. When the positioning plate 55 is inside the positioning groove, the mechanical claws A56 and B57 release their support for the reinforcing bars, allowing the reinforcing bars to automatically fall into the positioning grooves of the longitudinal positioning mechanism 3 and the transverse positioning mechanism 4, thus achieving precise feeding of the reinforcing bars. The straightening principle of the straightening mechanism 58 and the operating principle of the mechanical claws A56 and B57 are existing technologies and will not be described in detail here.
[0091] In order for the feeding mechanism 5 to feed materials to the longitudinal positioning mechanism 3 and the transverse positioning mechanism 4 respectively, refer to Figure 4 , Figure 10 and Figure 11 A frustum 18 is fixedly installed at one corner of the top of the base 1. The base plate 51 is slidably installed on the outside of the frustum 18 via a sliding sleeve 511. A rotating plate 512 is fixedly installed at the bottom of the base plate 51. One end of the rotating plate 512 can rotate even to the inside of the base 1. A motor C513 for driving the rotating plate 512 to rotate is fixedly installed at the top of the base 1. Hydraulic support legs 514 are symmetrically fixedly installed at the bottom of the base plate 51. A pad 515 is fixedly installed at the telescopic end of the bottom of the hydraulic support leg 514.
[0092] By rotating the base plate 51 to the outside of the frustum 18, the center of the frustum 18 is located at the intersection of the longitudinal positioning mechanism 3 and the transverse positioning mechanism 4 loading position. After the longitudinal positioning mechanism 3 completes the steel bar arrangement, the motor C513 drives the rotating plate 512 to rotate the base plate 51, so that the base plate 51 drives the hydraulic support arm 53 to rotate 90° to reach the loading position of the transverse positioning mechanism 4. Then, the hydraulic support leg 514 pushes the pad 515 to move downward to support the base plate 51, thus realizing the completion of two steel bar arrangements through one loading mechanism 5.
[0093] In summary, the rebar welding positioning device for producing and processing rebar mesh disclosed in this application operates by rotating the feeding mechanism 5 to the feeding position of the longitudinal positioning mechanism 3. The feeding mechanism 5 then straightens and transports the rebar forward via the straightening mechanism 58. When the end of the rebar reaches the outside of the positioning plate 55, the mechanical claws A56 and B57 close to support the bottom of the rebar, and the hydraulic support arm 53 pushes the positioning plate 55 forward. Simultaneously, the straightening mechanism 58 transports the straightened rebar forward, allowing the rebar to move forward while being straightened. After the positioning plate 55 moves forward a certain distance and aligns with the positioning groove directly below, the cutting blade 59 is pushed by the hydraulic push rod C510. When cutting the reinforcing bars, the straightening mechanism 58 clamps the reinforcing bars to ensure stable cutting. Finally, under the action of the hydraulic support 52, the hydraulic arm 53 moves the reinforcing bars downward. When the positioning plate 55 is inside the positioning groove, the mechanical claws A56 and B57 release their support for the reinforcing bars, allowing the reinforcing bars to automatically fall into the positioning groove inside the positioning seat A31, achieving precise feeding of the reinforcing bars. Subsequently, the display controller 17 controls the motor A37 to run, so that the motor A37 can drive the two chains B32 to run synchronously. Then, the chains B32 drive the positioning seat A31 and the reinforcing bars to move laterally. This process is repeated, and multiple positioning seats A31 can position and arrange the reinforcing bars, replacing traditional manual operation.
[0094] After the longitudinal positioning mechanism 3 completes the arrangement of the lower layer of reinforcing bars, the motor C513 drives the rotating plate 512 to rotate the base plate 51, causing the base plate 51 to rotate the hydraulic support arm 53 90° to the loading position of the transverse positioning mechanism 4. Then, the hydraulic support leg 514 pushes the pad 515 downward to support the base plate 51. After that, the loading mechanism 5 straightens and loads the reinforcing bars again, so that the longitudinal reinforcing bars are automatically placed in the positioning groove inside the positioning seat B43. At this time, the support block 435 in the positioning seat B43 supports the reinforcing bars, and the support block 435 located at the loading position faces upward under the action of the limiting plate 49, so that... When feeding the reinforcing bars, the support block 435 moves the reinforcing bars away from the limiting plate 49. Due to the pressure of the reinforcing bars, it always maintains a lifted state, which can move the reinforcing bars forward a certain distance, thus achieving precise lateral positioning. At the same time, the support block 435 will contact the push plate 26 and push it forward, so that the support block 435 simultaneously moves the push plate 26 and the reinforcing bars to the welding position. At this time, the push plate 26 drives the welding gun 22 to be above the welding position through the bearing plate 21. Then, under the action of the hydraulic push rod B45, the support 41 and the positioning seat B43 are moved down as a whole, so that the positioning seat B43 places the reinforcing bars on top of the lower layer of reinforcing bars.
[0095] During welding, the welding torch 22, driven by the positioning seat B43, is positioned at the first welding point of each longitudinal rebar. At this time, the electric push rod 256 pushes the welding torch 22 closer to the welding point by a certain distance. Finally, the welding end of the welding torch 22 tilts downwards and extends closer to the welding point, enabling the welding torch 22 to perform longitudinal welding. Then, the display controller 17 controls the motor A37 to run in reverse, causing the inner ring of the one-way bearing to rotate in reverse, thus preventing the sprocket B33 from rotating and keeping the positioned rebar stable. At this time, the motor A37 independently drives the pulley B38 to rotate in reverse. The pulley B38 drives the square rod 11 to rotate through the pulley A16, causing the square rod 11 to rotate through the gear A24. When the translation component 25 is in operation, one of the sprockets A251 in the translation component 25 rotates under the cooperation of gear A24 and gear B253, which in turn drives the chain A252 to drive the chain. The chain A252 drives the sliding pin 254 to move horizontally, which pushes the slider 255 to move longitudinally along the slide bar 258, thereby driving the welding torch 22 to move longitudinally. Welding is performed sequentially above each welding point. At this time, the operation of the translation component 25 is controlled by the motor A37. The motor A37 runs in reverse according to the positioning program input by the display controller 17, so there is no need to separately control the positioning of the welding torch 22, making the longitudinal movement and positioning of the welding torch 22 more convenient.
[0096] After each longitudinal steel bar is welded, the hydraulic push rod B45 drives the support 41 to move downwards, causing the positioning seat B43 to disengage from the end of the steel bar. This ensures the continuous operation of the chain C42. Once the positioning seat B43 is disengaged from the steel bar and loses its pressure, the counterweight block 437 presses down on the extension end of the extension plate 436, causing the extension plate 436 to rotate the support block 435 away from the end of the steel bar, changing it from a horizontal to a vertical position. This achieves the effect of the support block 435 automatically rotating and disengaging from the steel bar. As the chain C42 conveys the steel, when the positioning seat B43 moves to the end of the chain C42... At the bottom, the counterweight 437 causes the support block 435 to automatically rotate and reset. At this time, the support block 435 drives the rotating block 434 to press against the outside of the limiting platform 438. When the support block 435 moves back to the top of the chain C42, the limiting plate 49 causes the support block 435 that receives the steel bar to be in an open-facing state so as to receive the next steel bar. The support block 435 that does not receive the steel bar will automatically rotate to the side away from the end of the steel bar, so that the influence between the positioning seat B43 and the welded steel bar will be automatically eliminated each time the steel bar is positioned.
