Description

Technical Field

[0001] This invention relates to the field of steel cage welding technology, specifically a device for processing and welding steel cages for construction. Background Technology

[0002] In the fabrication of steel reinforcement cages, spiral stirrups are typically wound around the perimeter of long main reinforcement bars, and the contact points between the two are welded together to ensure the overall structural strength and stability of the cage. Existing steel reinforcement cage welding equipment generally includes a rotary drive mechanism for rotating the main reinforcement bars, a wire feeding mechanism for placing and guiding the stirrups, and a welding torch mechanism for performing the welding operation. During actual operation, the main reinforcement bars rotate around their axis under the drive mechanism, while the wire feeding mechanism continuously feeds and winds the stirrups onto the surface of the rotating main reinforcement bars. When the stirrups contact the main reinforcement bars and form an intersection point, the welding torch mechanism needs to move to that contact point to perform the welding.

[0003] However, existing equipment typically uses robotic arms or multi-axis linkage mechanisms to control the movement of the welding torch during the welding process. Because the main rib is continuously rotating, the welding torch needs to track the positional changes of the contact point in real time. This means that while the main rib is rotating, a complex control system drives the welding torch to move precisely in two or three dimensions along the axial and radial directions of the main rib to accurately reach the welding point. This welding method, which relies on the welding torch actively following the rotation of the main rib, places extremely high demands on the real-time performance and precision of the control system. This not only results in exceptionally complex motion control logic for the welding torch but also makes the equipment structure cumbersome, increasing manufacturing costs and maintenance difficulty, and hindering further improvements in welding efficiency and automation. Therefore, it is necessary to improve the structure of existing welding equipment to simplify the welding head control method and enhance the stability and efficiency of the welding process. Summary of the Invention

[0004] This invention provides a device for processing and welding steel reinforcement cages for buildings, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A building steel cage processing and welding device includes a support rail, a fixed base in the middle of the support rail, a central support plate on the fixed base, and multiple main steel bars passing through the central support plate. It also includes a steel bar clamping mechanism, a welding mechanism, and an end lifting mechanism.

[0007] An end support mechanism is provided on both sides of the support rail to support the two ends of the main rib and drive the main rib to move along the length of the support rail.

[0008] A rebar clamping mechanism is disposed on the central support plate to limit the spacing between adjacent main bars and drive multiple main bars to rotate synchronously around the central axis of the central support plate;

[0009] A welding mechanism, located on the side of the fixed base, is used to wrap the stirrups around the outer periphery of the main reinforcement during the rotation of the main reinforcement, and to perform welding operations at the contact point between the stirrups and the main reinforcement.

[0010] As a preferred embodiment of the present invention, the welding mechanism includes a fixed plate fixedly connected to the fixed base, a support seat provided in the middle of the fixed plate, a deflection beam rotatably connected to the middle of the end of the support seat, a support wheel rotatably connected to the end of the deflection beam near the main reinforcement, the diameter of the support wheel being larger than the distance between two adjacent main reinforcements, and a welding assembly for welding the contact point between the main reinforcement and the stirrups provided on the side of the deflection beam away from the fixed plate, wherein when the support wheel abuts against the surfaces of two adjacent main reinforcements simultaneously, the distance between the welding assembly and the stirrups is within a preset welding distance range.

[0011] As a preferred embodiment of the present invention, the side of the support base is provided with an angle reset component for driving the deflection beam to a horizontal state reset, the rotation center of the deflection beam and the rotation center of the main reinforcement are located at the same horizontal height, and the end of the fixing plate away from the main reinforcement is provided with an unwinding component for releasing the stirrups.

[0012] As a preferred embodiment of the present invention, the angle reset assembly includes a fixed block disposed on the side of the support base, a sliding rod fixedly connected to the fixed block, a reset slider slidably connected to the middle of the sliding rod, a buffer spring sleeved on the outside of the sliding rod, the buffer spring being used to drive the reset slider to move toward the fixed plate, one end of a support rod being rotatably connected to the side of the reset slider, and the other end of the support rod being rotatably connected to the end of the deflection beam away from the main rib.

[0013] As a preferred embodiment of the present invention, the welding assembly includes an extended bracket fixedly connected to the deflection beam, a rotating seat rotatably connected to the end of the extended bracket, a welding head slidably connected to the middle of the rotating seat, a limiting plate provided on the side of the support seat, and a top head cooperating with the limiting plate provided on the side of the deflection beam.

[0014] As a preferred embodiment of the present invention, the unwinding assembly includes an extended support arm fixedly connected to the end of the fixed plate, and a winding wheel for winding the stirrup is rotatably connected to the end of the extended support arm. A suspension rod is provided on the side of the deflection beam near the fixed base, and a guide ring is provided at the end of the suspension rod. The stirrup passes through the guide ring.

[0015] As a preferred embodiment of the present invention, the side of the support base away from the fixed plate is rotatably connected to a guide wheel that cooperates with the stirrup. The side of the support base near the fixed plate is provided with a vertical groove, and a tensioning block is slidably connected in the groove. The side of the tensioning block is rotatably connected to a tensioning wheel that cooperates with the stirrup. A tensioning spring is provided inside the groove, and the tensioning spring is used to drive the tensioning block to move toward the fixed plate.

[0016] As a preferred embodiment of the present invention, the rebar clamping mechanism includes a clamping rotating disk rotatably connected to the center of the central support plate. The clamping rotating disk is symmetrically provided with a plurality of positioning grooves for accommodating the main rebar along the circumferential direction. A fixed wheel is provided at one end of the positioning groove near the center of the clamping rotating disk. A positioning slider is slidably connected in the positioning groove. A positioning wheel corresponding to the fixed wheel is provided on the side of the positioning slider near the center of the clamping rotating disk. One end of a positioning screw is rotatably connected to the side of the positioning slider away from the center of the clamping rotating disk. The other end of the positioning screw is threadedly connected to the end of the positioning groove.

[0017] As a preferred embodiment of the present invention, the end lifting mechanism includes two transverse seats slidably connected to the surface of the support track. A lifting turntable is rotatably connected to the middle of the transverse seats. A pulling clamping head for clamping and fixing the end of the main rib is provided on the lifting turntable near the feeding direction of the main rib. A lifting slider is slidably connected on the lifting turntable away from the feeding direction of the main rib. The end of the main rib passes through the middle of the lifting slider.

[0018] As a preferred embodiment of the present invention, a rotating rod is provided at the bottom of the support rail, and a support seat for supporting the main rib is rotatably connected to the side of the rotating rod.

[0019] The present invention has the following advantages:

[0020] 1. This device achieves passive following motion of the welding assembly through a unique mechanical structure design. During the rotation of the main reinforcement bar, its outer circumference directly pushes the support wheel, which in turn drives the deflection beam to deflect synchronously with the welding assembly, enabling the welding head to automatically align with the contact point between the stirrup and the main reinforcement bar for welding. This purely mechanical following method completely eliminates the active tracking mode of traditional devices that rely on servo motors, multi-axis robots, and complex control algorithms, greatly simplifying the hardware configuration and software programming difficulty of the control system, and fundamentally solving the technical problem of complex welding head control.

[0021] 2. Because the welding head does not require complex active control and real-time position feedback, this device significantly reduces the manufacturing and subsequent maintenance costs. On one hand, it eliminates the need for high-precision motion control cards, sensors, and actuators; on the other hand, the mechanical structure boasts higher reliability and stability, a lower failure rate, and simplified daily maintenance and repair. Simultaneously, the buffer spring in the angle reset assembly effectively absorbs vibrations during deflection, ensuring the stability of the welding head at the moment of welding, thereby improving the consistency of welding quality.

[0022] 3. This device, through the cooperation of the support rail and the end lifting mechanism, achieves stable support and continuous feeding of ultra-long main reinforcing bars, significantly extending the single processing length of the reinforcing cage. The dynamic switching function of the lifting seat fills the support gap during the movement of the transverse seat, effectively preventing the main reinforcing bars from bending and deforming due to their own weight, and ensuring the dimensional and positional accuracy of long workpieces during rotation and movement. In addition, the adaptive adjustment function of the stirrup tensioning structure ensures that the stirrups are always wound with constant tension around the outer periphery of the main reinforcing bars, further improving the processing quality and overall structural strength of the reinforcing cage.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] In one embodiment, see Figure 1 A rebar cage processing and welding device for construction includes a support rail 1. In a preferred embodiment, the support rail 1 is composed of two parallel H-beams arranged in a front-to-back direction. A fixed base 2 is fixedly installed in the middle of the support rail 1, and the lower surface of the fixed base 2 is fixedly connected to the upper surface of the support rail 1 on both sides. A central support plate 3 is fixedly installed above the fixed base 2, and multiple main reinforcing bars 5 are threaded through the central support plate 3. According to conventional construction requirements, four main reinforcing bars 5 are preferably arranged in parallel in this embodiment. The device also includes a rebar clamping mechanism 4, a welding mechanism 8, and an end lifting mechanism 7.

[0036] The rebar clamping mechanism 4 is used for positioning, spacing limitation, and rotation drive of the main rebars 5; the end lifting mechanism 7 is used for supporting both ends of the main rebars 5 and driving their axial movement; and the welding mechanism 8 is used for conveying, winding, and welding the stirrups 6. The three mechanisms work together to complete the integrated processing and manufacturing of the rebar cage.

[0037] In one instance of this embodiment, please refer to Figure 1 , Figure 2 and Figure 7 The rebar clamping mechanism 4 is the core driving component for rebar cage processing and is located at the center of the central support plate 3. Specifically, a through hole is formed in the center of the central support plate 3, and the inner wall of the through hole is rotatably connected to the outer wall of the clamping rotating disk 35 via a bearing. The clamping rotating disk 35 is a disc-shaped structure, and its axis is collinear with the axis of the through hole in the central support plate 3. Multiple positioning grooves 36 are radially formed on the outer end face of the clamping rotating disk 35. These positioning grooves 36 are radially distributed relative to the center of the clamping rotating disk 35 and symmetrically arranged along the circumference. The number of positioning grooves 36 corresponds one-to-one with the number of main reinforcing bars 5. In this embodiment, since four main reinforcing bars 5 are used, four positioning grooves 36 are provided.

[0038] A fixed wheel 40 is fixedly installed at one end of each positioning groove 36 near the center of the clamping rotating disk 35. The fixed wheel 40 is preferably a rubber wheel, and its outer circumferential surface is used to abut against the surface of the main rib 5. A positioning slider 38 is slidably connected within the positioning groove 36 along its extending direction. A positioning wheel 39 is rotatably connected to the side of the positioning slider 38 near the center of the clamping rotating disk 35 via a rotating shaft. The positioning wheel 39 and the fixed wheel 40 are correspondingly arranged, and their outer circumferential surfaces together form a clamping space that matches the outer contour of the main rib 5. One end of a positioning screw 37 is rotatably connected to the side of the positioning slider 38 away from the center of the clamping rotating disk 35 via a bearing. The other end of the positioning screw 37 passes through the end of the positioning groove 36 and is threadedly connected to that end. For ease of operation, a polygonal quick-release structure, such as a hexagonal head, can be provided in the middle of the positioning screw 37. This allows the positioning screw 37 to be rotated using a wrench or other tools, driving the positioning slider 38 to slide along the positioning groove 36, thus achieving the clamping and releasing of the main rib 5 by the positioning wheel 39 and the fixed wheel 40.

[0039] During operation, the main reinforcing bar 5 is first inserted between the fixed wheel 40 and the positioning wheel 39. Then, the positioning screw 37 is rotated, and the positioning slider 38 is moved towards the center of the clamping rotating disk 35 by the threaded transmission until the positioning wheel 39 and the fixed wheel 40 clamp the main reinforcing bar 5 together, thus completing the positioning and fixing of a single main reinforcing bar 5 and ensuring that multiple main reinforcing bars 5 are evenly distributed in a circle. The clamping rotating disk 35 is driven to rotate by a drive motor (not shown in the figure), which in turn drives multiple main reinforcing bars 5 to rotate synchronously around the central axis of the central support plate 3, providing stable rotational power for the subsequent winding of the stirrups 6.

[0040] In one instance of this embodiment, please refer to Figure 1 , Figure 8 and Figure 9 The end support mechanism 7 is located on the front and rear sides of the support rail 1 to support the front and rear ends of the main reinforcement 5, prevent the main reinforcement 5 from bending and deforming due to its own excessive weight, and drive the main reinforcement 5 to move at a constant speed along the length direction of the support rail 1. The rotation of the main reinforcement 5 is coordinated to realize the continuous spiral winding of the stirrup 6.

[0041] Specifically, the end lifting mechanism 7 includes two transverse sliding seats 41, which are slidably connected to the front and rear ends of the upper surface of the support rail 1, respectively. To achieve smooth sliding, rollers with motors can be installed inside the transverse sliding seats 41, and the synchronous movement of the two transverse sliding seats 41 is achieved by the rollers rolling along the inner side of the support rail 1. A lifting turntable 42 is rotatably connected to the middle of each transverse sliding seat 41 via a bearing. To ensure that the main rib 5 remains horizontal and stable during rotation, the lifting turntable 42 is set at the same height as the clamping turntable 35, and their installation methods are similar.

[0042] A traction clamping head 43 is fixedly installed on the lifting turntable 42 (i.e., the front lifting turntable 42) near the feed direction of the main rib 5. In use, the front end of the main rib 5 is bent and closed, and the end is fixedly connected to the traction clamping head 43. The movement of the front traction clamping head 43 drives the entire main rib 5 forward axially. A groove is radially formed on the lifting turntable 42 (i.e., the rear lifting turntable 42) away from the feed direction of the main rib 5. A lifting slider 46 is slidably connected within this groove. A through hole is formed inside the lifting slider 46, through which the rear end of the main rib 5 can pass and be simply fixed. This allows the rear transverse seat 41 and the lifting turntable 42 to move forward adaptively as the main rib 5 moves forward, ensuring that the rear end of the main rib 5 is always effectively supported.

[0043] In addition, to provide auxiliary support for the middle part of the main rib 5, multiple rotating rods 44 are evenly arranged along the length of the bottom of the support rail 1. The rotating rods 44 are arranged in a left-right direction, and a support seat 45 is rotatably connected to their sides. The end of the support seat 45 is preferably a semi-circular structure so as to fit against the outer peripheral surface of the main rib 5. A driving device (such as a cylinder, not shown in the figure) is provided inside the rotating rod 44 to drive the support seat 45 to rotate around the central axis of the rotating rod 44. In actual operation, when the main rib 5 is above the rotating rod 44, the driving device will drive the support seat 45 to rotate to a vertical state, so that the semi-circular structure of the support seat 45 above it supports the main rib 5, and this structure does not affect the normal rotation of the main rib 5. As a dynamic adjustment strategy, in the initial state, the support seat 45 located on the rear side of the support rail 1 is in a vertical state, while the support seat 45 located on the front side is in a horizontal state. When the rear transverse seat 41 moves forward and approaches a certain support seat 45, the corresponding rotating rod 44 of the support seat 45 will drive it to rotate to a horizontal state, so that the rear transverse seat 41 can smoothly pass over the support seat 45 and continue forward. At the same time, after the front transverse seat 41 moves forward, the support seat 45 corresponding to the gap left behind it will rotate to a vertical state, timely supporting the upper main rib 5. Through this arrangement, the support seat 45 can effectively fill the support gap between the front and rear support mechanisms, provide auxiliary support for the main rib 5, and further prevent the main rib 5 from bending due to excessive length and weight, ensuring the overall stability of the main rib 5 during rotation and axial movement.

[0044] In one instance of this embodiment, please refer to Figures 1-6 The welding mechanism 8 is located on the side of the fixed base 2 and adjacent to the central support plate 3. It is the core component for realizing the winding and welding of the stirrup 6. Its function is to continuously wind the stirrup 6 around the outer circumference of the main rib 5 when the main rib 5 rotates, and to achieve precise welding at the contact point between the stirrup 6 and the main rib 5. A major feature of this mechanism is that the welding assembly 15 can passively follow the rotation of the main rib 5, without the need for a complex active control system.

[0045] The welding mechanism 8 includes a fixing plate 9 fixedly connected to the fixing base 2. In this embodiment, the fixing plate 9 is arranged approximately in a left-right direction on the front right side of the fixing base 2. Viewed from the front, the main rib 5 rotates counterclockwise with the clamping rotating disk 35. A support seat 11 is vertically fixed to the middle of the fixing plate 9, and two support seats 11 are symmetrically arranged. The upper end of each support seat 11 is rotatably connected to the middle of a deflection beam 12, and the two deflection beams 12 rotate synchronously, with their left ends able to flip up and down. A support wheel 14 is rotatably connected to the left end of the deflection beam 12, on the side furthest from the center of the fixing plate 9. When the deflection beam 12 rotates to a horizontal state, the center of the support wheel 14 is at the same horizontal height as the center of the clamping rotating disk 35.

[0046] The support wheel 14 is preferably a wear-resistant metal wheel with a diameter larger than the distance between two adjacent main reinforcing bars 5, to ensure that the support wheel 14 can simultaneously abut against the outer peripheral surfaces of the two adjacent main reinforcing bars 5. A welding assembly 15 is fixedly installed on the left side of the deflection beam 12 near the center of the fixing plate 9. The welding assembly 15 includes an extension bracket 18 fixedly connected to the deflection beam 12, which extends upward and has a rotating seat 17 rotatably connected to its end. A long strip-shaped welding head 16 is slidably connected to the middle of the rotating seat 17, preferably an arc welding welding head 16. By adjusting the rotation angle of the rotating seat 17 and the forward and backward extension position of the welding head 16, it can be ensured that when the support wheel 14 abuts against the surfaces of the two adjacent main reinforcing bars 5 simultaneously, the distance between the welding head 16 of the welding assembly 15 and the stirrup 6 is within a preset welding distance range, thereby ensuring welding accuracy.

[0047] During operation, when the main reinforcing bar 5 rotates around its central axis, its outer circumference pushes the support wheel 14 in a circular motion, which in turn drives the deflection beam 12 to perform a synchronous circular deflection motion around its connection point with the support base 11. The welding assembly 15 moves synchronously with the deflection beam 12, thereby achieving passive following of the contact point between the main reinforcing bar 5 and the stirrup 6 by the welding head 16. This design completely eliminates the traditional complex control system and greatly simplifies the control logic. In addition, as a preferred option, a limiting plate 33 can be set on the side of the support base 11, and a top head 34 can be set on the side of the deflection beam 12. When the deflection beam 12 deflects to a horizontal state, the top head 34 contacts the limiting plate 33, which acts as a limit. At the same time, a pressure sensor (not shown in the figure) can be set on the limiting plate 33. When the top head 34 contacts the limiting plate 33, it triggers the welding head 16 to perform welding, thereby achieving intermittent automatic welding by the welding head 16 and avoiding continuous ineffective operation of the welding head 16.

[0048] In one instance of this embodiment, please refer to Figures 1-6 An angle reset component 13 is provided on the side of the support base 11 to drive the deflection beam 12 to reset to a horizontal state, ensuring that the support wheel 14 is always in close contact with the surface of the main rib 5, and preventing the welding component 15 from shifting due to gaps caused by the rotation of the main rib 5.

[0049] The angle reset assembly 13 includes a fixing block 19 fixedly installed on the side of the support base 11. A sliding rod 21 is fixedly connected to the fixing block 19 in the vertical direction, and a reset slider 22 is slidably connected to the middle of the sliding rod 21 along its axis. A buffer spring 20 is sleeved on the outside of the sliding rod 21. One end of the buffer spring 20 is connected to the fixing block 19, and the other end is connected to the reset slider 22. Its elastic force is directed to push the reset slider 22 upward. The lower end of a support rod 23 is rotatably connected to the side of the reset slider 22 via a pivot, and the upper end of the support rod 23 is rotatably connected to the right end of the deflection beam 12 via a pivot.

[0050] When the deflection beam 12 deflects upwards along with the main rib 5, the right end of the deflection beam 12 moves downwards, driving the reset slider 22 to slide downwards along the sliding rod 21 via the support rod 23. At this time, the buffer spring 20 is further compressed. After the support wheel 14 passes over a main rib 5, under the energy release action of the buffer spring 20, the left end of the deflection beam 12 swings downwards rapidly, causing the support wheel 14 to immediately abut against the surface of the next main rib 5. This structure ensures that the support wheel 14 can maintain continuous and close contact with the surface of the main rib 5, guaranteeing the following stability of the welding assembly 15. At the same time, the buffer spring 20 can also absorb the vibration generated during the deflection of the deflection beam 12, which is beneficial to improving welding accuracy.

[0051] In one instance of this embodiment, please refer to Figures 1-6 The fixed plate 9 is provided with an unwinding assembly 10 at the end away from the main reinforcement 5, which is used to store and continuously release the stirrups 6 to provide raw materials for the winding operation.

[0052] The unwinding assembly 10 includes an extension arm 31 fixedly connected to the right end of the fixed plate 9. The extension arm 31 extends upward and to the right, and its end is rotatably connected to a winding wheel 32 via a pivot. The stirrup 6 is wound in a coil form onto the winding wheel 32, which can rotate freely to achieve continuous release of the stirrup 6. To control the unwinding speed, a damping device (not shown in the figure) can be installed inside the winding wheel 32. When the free end of the stirrup 6 is pulled out, the winding wheel 32 rotates adaptively.

[0053] A suspension rod 24 is vertically fixed to the side of the deflection beam 12 near the fixed base 2. In this embodiment, the suspension rod 24 is located on the lower left side of the deflection beam 12 and extends downward to the left. The lower ends of the two suspension rods 24 are jointly fixedly connected to a guide ring 25. The free end of the stirrup 6 passes through the guide ring 25 from bottom to top. The guide ring 25 guides the stirrup 6, ensuring that the stirrup 6 can be accurately delivered to the winding position of the main reinforcement 5. After the stirrup 6 passes through the guide ring 25, it further rotates around the outer circumference of the guide wheel 26, which is rotatably connected to the center position above the support base 11. The guide wheel 26 is used to perform secondary correction on the delivery direction of the stirrup 6 to prevent deviation.

[0054] To prevent the stirrups 6 from loosening during transport and winding, and to ensure they are tightly wound around the outer periphery of the main reinforcement 5, a vertical groove 30 is provided at the lower part of the support base 11. A tensioning block 28 is slidably connected vertically within the groove 30, and a tensioning wheel 27 is rotatably connected to the side of the tensioning block 28 via a rotating shaft. After passing through the guide wheel 26, the stirrups 6 are wound around the outer periphery of the tensioning wheel 27. A tension spring 29 is installed inside the groove 30, with one end abutting against the top inner wall of the groove 30 and the other end abutting against the top of the tensioning block 28. The tension spring 29 is always in a compressed state, and its elastic force drives the tensioning block 28 downward, thereby causing the tensioning wheel 27 to press down, generating a continuous tension force on the stirrups 6.

[0055] When the stirrup 6 becomes slightly loose during winding, the tension spring 29 pushes the tension block 28 downwards, tightening the loosened stirrup 6 through the tension wheel 27. When the tension of the stirrup 6 becomes too great during transport, the stirrup 6 pulls the tension wheel 27 upwards, further compressing the tension spring 29, thus buffering the excessive tension and achieving self-adaptive tension of the stirrup 6. This design ensures that the stirrup 6 is always wound around the outer periphery of the main reinforcement 5 with a constant tension, guaranteeing the winding quality.

[0056] The workflow of the steel reinforcement cage processing and welding device for this building mainly includes five stages: clamping and positioning of the main reinforcement 5, adjusting equipment parameters, threading and tensioning of the stirrups 6, winding and welding operations, and unloading of the finished product, as detailed below:

[0057] 1. Main Rib 5 Clamping and Positioning: Multiple main ribs 5 are sequentially passed through the positioning wheel 39 and fixed wheel 40 within the positioning groove 36. Then, the rear end of each main rib 5 is inserted into the through hole of the lifting slider 46, and the front end of each main rib 5 is bent and fixedly connected to the front pulling clamp head 43. At this time, the front transverse seat 41 is close to the fixed base 2, and the rear transverse seat 41 is away from the fixed base 2. Adjust the lifting seat 45 at the bottom of the support rail 1 so that it abuts against the lower side of the main rib 5, completing the full support and positioning of the main rib 5.

[0058] 2. Equipment parameter adjustment: According to the design parameters of the steel cage to be processed, adjust the height of the welding head 16 of the welding assembly 15 to ensure that when the support wheel 14 abuts against the adjacent main bar 5, the welding head 16 is within the preset welding distance range; adjust the initial compression of the tension spring 29 to ensure that the tension of the stirrup 6 meets the winding requirements; set the uniform sliding speed of the transverse seat 41 to determine the axial movement speed of the main bar 5, and calculate the spiral winding pitch of the stirrup 6 in conjunction with the rotation speed of the clamping rotating disk 35.

[0059] 3. Tensioning and tightening the stirrup 6: The coiled stirrup 6 is placed on the winding wheel 32. Then, the free end of the stirrup 6 is passed sequentially through the tensioning wheel 27, the guide wheel 26, and the guide ring 25. Finally, the end of the stirrup 6 is fixed to the end of one of the main reinforcing bars 5. At this time, the tension spring 29 applies initial tension to the stirrup 6 through the tensioning block 28 and the guide wheel 26, ensuring that the stirrup 6 does not slack off.

[0060] 4. Winding Welding Operation: The drive clamping rotary table 35 rotates, thereby driving multiple main reinforcing bars 5 to rotate synchronously counterclockwise around the central axis. Simultaneously, the drive transverse sliding seat 41 slides forward at a uniform speed along the support track 1, pulling the clamping head 43 to drive the main reinforcing bars 5 to move axially at a uniform speed. The rotation and axial movement of the main reinforcing bars 5 work together to make the stirrups 6 continuously spirally wind around the outer circumference of the main reinforcing bars 5. During the rotation of the main reinforcing bars 5, their surface pushes the support wheel 14 to make a circular motion, thereby driving the deflection beam 12 and the welding assembly 15 to passively follow. The welding assembly 15 is started, and when the welding head 16 moves to the contact point between the main reinforcing bar 5 and the stirrup 6, welding is performed to achieve a fixed connection between the stirrup 6 and the main reinforcing bar 5. Throughout the welding process, the angle reset assembly 13 ensures that the support wheel 14 is continuously in close contact with the surface of the main reinforcing bar 5, while the stirrup 6 tensioning structure always provides a constant tension force to the stirrup 6, jointly ensuring the winding and welding quality.

[0061] 5. Finished Product Unloading: After the main reinforcement 5 completes the axial movement of the preset length, i.e., after the winding and welding of the stirrups 6 are completed, the drive motors of the welding assembly 15, the clamping rotating disk 35, and the transverse moving seat 41 are turned off in sequence. Then, the pulling clamping head 43 and the lifting slider 46 are released, the positioning screw 37 is rotated in the opposite direction to release the main reinforcement 5, and finally the processed steel cage is taken out of the device to complete the entire processing flow.

[0062] This invention provides a welding device for processing building steel reinforcement cages. The rotating main reinforcement bar 5 drives the deflection beam 12 of the welding mechanism 8 to move up and down, allowing the welding assembly 15 to intermittently and passively weld the contact points between the main reinforcement bar 5 and the stirrups 6. During operation, the entire device only needs to drive the rotation and axial movement of the main reinforcement bar 5, with the stirrups 6 passively wrapped around the outside of the main reinforcement bar 5, and the welding assembly 15 passively welding the contact points. This design completely eliminates the need for the complex precision control system of the welding head 16 in traditional devices, significantly reducing manufacturing costs and control complexity. Simultaneously, the use of the support rail 1 structure removes limitations on the processing length of the steel reinforcement cage, greatly improving processing efficiency and applicability.

Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
