Description

Technical Field

[0001] This invention relates to the field of rebar cage processing technology, specifically to an integrated rebar cage feeding and welding processing device. Background Technology

[0002] In the construction of bridge pile foundations, underground engineering, and large foundation structures, the reinforcing cage is the core load-bearing skeleton of the concrete structure, and its fabrication quality directly affects the bearing capacity of the pile foundation and the overall structural safety. With the expansion of project scale and the increasing requirements for construction schedule, the processing of reinforcing cages has gradually shifted from traditional manual methods to mechanization and automation.

[0003] In traditional construction practices, rebar cage fabrication is mostly completed using semi-automatic equipment combined with manual operation. Main reinforcing bars are typically moved to the fabrication platform manually, and their spacing is determined by manual placement and alignment; the winding of stirrups requires manual control of tension and pitch; and welding is performed manually with a welding torch. This method can meet basic construction needs for small-scale projects or projects with moderate quality requirements, but its limitations become increasingly apparent in large-scale, high-precision fabrication environments.

[0004] Due to the large length and weight of the reinforcing cage, and the numerous and densely arranged main bars, high requirements are placed on coaxiality, spacing accuracy, and welding quality during processing. Manual positioning often relies on experience and visual adjustment, making errors in main bar spacing and weld point positions difficult to avoid. When welding quality control is unstable, problems such as incomplete welds, missed welds, or insufficient weld strength can easily occur, affecting structural safety. Simultaneously, pitch control during stirrup winding depends on manual coordination. If the rotation speed and bar feeding speed are not properly matched, uneven pitch or localized accumulation can easily occur, affecting not only appearance quality but also potentially increasing material consumption. After processing, manual rotation and movement of the reinforcing cage are still required, resulting in high labor intensity and safety risks. Furthermore, in the production of multi-specification reinforcing cages, traditional equipment parameter adjustments are cumbersome, process connections rely on manual coordination, and the lack of unified control logic between functional units easily leads to downtime or repeated adjustments, reducing overall production efficiency.

[0005] With the continuous improvement of construction mechanization, standardization, and intelligent manufacturing, the reliance on manual experience in rebar cage processing has gradually become a significant factor restricting the stability of processing quality, the improvement of production efficiency, and the assurance of construction safety. Under the premise of ensuring the structural performance and welding quality of the rebar cage, achieving automated and coordinated control of main reinforcement feeding, positioning welding, stirrup winding, and finished cage unloading, reducing manual intervention, and improving processing continuity and consistency, has significant engineering implications and practical application value for upgrading rebar cage processing equipment. Therefore, we are introducing an integrated rebar cage feeding and welding collaborative processing device. Summary of the Invention

[0006] The purpose of this invention is to provide an integrated feeding and welding processing device for steel cages to solve the problems mentioned in the background art.

[0017] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention is sequentially divided into a main reinforcement feeding and welding area, a cage forming area, a stirrup winding and welding area, and a stirrup feeding area. Each functional unit is arranged sequentially according to the processing flow, forming a continuous processing flow during the main reinforcement feeding, positioning welding, stirrup winding, and cage unloading processes. Throughout the entire processing, no direct manual intervention is required for welding and winding operations, allowing the steel cage to complete continuous forming operations through the coordinated cooperation of various systems. During the processing, the main reinforcement is automatically arranged, positioned, and welded, and the stirrups are automatically wound and synchronously welded, thereby achieving integrated automatic control of the entire steel cage forming process, reducing manual intervention, and improving processing accuracy and production efficiency.

[0018] This invention employs an adjustable design in its equipment structure, enabling the device to adapt to the processing requirements of rebar cages of different specifications. Specifically, the arc-shaped concave grippers in the rotary drive mechanism are driven by four hydraulic cylinders, allowing for radial extension and retraction adjustment according to the diameter of the rebar cage, thus achieving stable clamping and support for rebar cage skeletons of different diameters. Simultaneously, the inner shaft and the telescopic cylinder sleeved on its outer side have axial extension and retraction functions, allowing the overall length of the rotary drive mechanism to be adjusted according to processing requirements, thereby meeting the forming requirements of rebar cages of different lengths.

[0019] The tension adjustment mechanism of the stirrup winding and welding system adjusts the tension of the upper and lower stirrups to prevent the stirrups from becoming loose or overly tight, which could cause winding deviation. The linkage drive structure of the material distribution mechanism can drive the main bar material distribution hook to rotate simply by extending and retracting the drive cylinder, so as to separate the main bars one by one. The structure is compact and the drive is efficient, avoiding blockage caused by the simultaneous feeding of multiple main bars and improving the feeding efficiency. Attached Figure Description

[0022] 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.

[0023] Example: Please see Figures 1-17 The present invention provides a technical solution: A rebar cage integrated feeding and welding processing device includes a stirrup feeding system 1, a stirrup winding welding system 2, a rebar cage rolling system 3, and a main bar feeding and welding system 5 arranged in sequence.

[0024] The steel cage rolling system 3 includes a third slide rail 301, two sets of third slide blocks 302 symmetrically slidably connected on the third slide rail 301, a movable platform 303 fixed at the upper end of the third slide block 302, and a rotating shaft 304 rotatably arranged at the inner end of the movable platform 303. The rotation drive mechanism 305 includes an inner shaft rod 3051 fixed at the inner end of the rotating shaft 304, a telescopic cylinder 3052 sleeved on the outer side of the inner shaft rod 3051, hydraulic cylinders 3053 distributed in a circular and equally spaced manner on the outer side of the telescopic cylinder 3052, and an arc-shaped concave gripper 3055 fixed at the end of the piston rod 3054 at the output end of the hydraulic cylinder 3053. Annular reinforcing ribs 601 are sleeved and fixed on the outer side of several sets of arc-shaped concave grippers 3055.

[0025] Support frames 306 are provided at equal intervals between the third slide rails 301. The rotary drive mechanism 305 adopts a drive structure of "inner shaft rod 3051 + telescopic cylinder 3052 + hydraulic cylinder 3053 + arc-shaped concave gripper 3055". The hydraulic cylinder 3053 drives the piston rod 3054 to move the arc-shaped concave gripper 3055 to extend and retract, which can quickly realize the clamping and loosening of the annular reinforcing rib 601. The operation is convenient. The arc-shaped concave gripper 3055 fits tightly with the inner wall of the annular reinforcing rib 601, clamping firmly and preventing the annular reinforcing rib 601 from shifting during the welding process. The telescopic cylinder 3052 can be adapted to annular reinforcing ribs 601 of different diameters, further improving the versatility of the device.

[0026] The main reinforcement feeding and welding system 5 uses its material distribution mechanism to separate the uniformly stored main reinforcement bars 603 one by one and transport them to the forming station on the rebar cage rolling system 3. Subsequently, the main reinforcement feeding and welding system 5 uses its main reinforcement welding gun 50408 to weld the main reinforcement bars 603 to the outside of the annular reinforcing bars 601 on the rebar cage rolling system 3. The main reinforcement feeding and welding system 5 includes a fourth slide rail 501, a first main reinforcement axial positioning mechanism 502 and a second main reinforcement axial positioning mechanism 503 sliding on both sides of the fourth slide rail 501, and several sets of main reinforcement storage mechanisms 504 sliding on the fourth slide rail 501. The several sets of main reinforcement storage mechanisms 504 are arranged between the first main reinforcement axial positioning mechanism 502 and the second main reinforcement axial positioning mechanism 503. The first main reinforcement axial positioning mechanism 502 includes a mechanism that slides on the fourth slide rail 501. The slide rail 501 includes a first control cabinet 5021, two sets of first hydraulic support columns 5022 extending through the first control cabinet 5021, a control main unit box 5023 with a first support platform 5026 at the upper end of the two sets of first hydraulic support columns 5022, two sets of hydraulic telescopic shafts 5025 extending through the side of the control main unit box 5023, and a first main rib axial limiting baffle 5024 fixed between the ends of the two sets of hydraulic telescopic shafts 5025. The second main rib axial positioning mechanism 503 includes a second control cabinet 5031 slidably connected to the fourth slide rail 501, two sets of second hydraulic support columns 5032 extending through the second control cabinet 5031, and a second main rib axial limiting baffle 5034 centrally located with a second support platform 5035 at the upper end of the two sets of second hydraulic support columns 5032.

[0027] The main reinforcement storage mechanism 504 includes a third control cabinet 50401 slidably connected to a fourth slide rail 501, a movable support 50405 mounted on the third control cabinet 50401, and a main reinforcement storage inclined platform 50414 for stacking main reinforcement 603, mounted on a vertical frame 50409 at the upper end of the third control cabinet 50401. The inclined platform 50414 has reinforcement-blocking toothed plates 50410 on both sides of its top end. The material distribution mechanism includes bearing seats 50412 mounted on both sides of the end of the vertical frame 50409, and a rotating rod 50411 extending through and out of the bearing seats 50412. The rotating rod 50411 has several sets of main rib material distribution hooks 50413 fixed on it, a driven gear 50415 fixed at the bottom of the main rib material distribution hooks 50413 located between two sets of bearing seats 50412, and a drive gear 50416 movably connected at the end of the upright frame 50409. The top of the drive gear 50416 meshes with the bottom of the driven gear 50415. The bottom of the drive gear 50416 is connected to a ball 50419 by a lever 50417. The ball 50419 is located between two sets of limiting plates 50418 at the top of the movable bracket 50405.

[0028] The main rib storage mechanism 504 features an inclined storage platform 50414 for storing main ribs. Combined with the baffle toothed plate 50410, this allows for the orderly stacking of main ribs 603 and facilitates their natural descent under gravity, reducing manual intervention. The material distribution mechanism employs a linkage drive structure consisting of a drive cylinder 50404, a ball 50419, a lever 50417, a drive gear 50416, a driven gear 50415, and a main rib distribution hook 50413. The extension and retraction of the drive cylinder 50404 alone can rotate the main rib distribution hook 50413, enabling the separation of each main rib 603. This compact and efficient structure avoids blockages caused by the simultaneous transport of multiple main ribs 603, thus improving material supply efficiency.

[0029] The upper part of the third control cabinet 50401 is provided with two sets of light rods 50402, and the bottom sides of the movable bracket 50405 are provided with movable seats 50403. The light rods 50402 extend through the movable seats 50403, and the upper part of the third control cabinet 50401 is also provided with a drive cylinder 50404 for driving the movable seats 50403 to move along the light rods 50402.

[0030] The movable bracket 50405 has a main rib guide inclined rail 50406 at the top, and a main rib limiting block 50407 at the top end of the main rib guide inclined rail 50406. The main rib welding gun 50408 is fixed to the side of the end of the main rib guide inclined rail 50406.

[0031] The stirrup feeding system 1 is used to supply upper stirrups 109 and lower stirrups 108 distributed vertically to the stirrup winding and welding system 2. The stirrup feeding system 1 includes a first slide rail 101, a first slide block 102 slidably connected to the first slide rail 101, a turntable 103 on the first slide block 102 for placing stirrup coils 110, stirrup fixing brackets 106 with equal circular spacing distributed at the upper end of the turntable 103, annular reinforcing members 107 on the stirrup fixing brackets 106, and a fixed ring at the upper end of the turntable 103. A fixed annular support frame 105 is coaxially arranged outside several sets of stirrup fixing brackets 106. Stirrup coils 110 are sleeved on the outside of several sets of stirrup fixing brackets 106. The annular support frame 105 is located outside the stirrup coils 110. The upper stirrup 109 extends out through the top wire feeding of the corresponding stirrup coil 110. The first slide 102 is also provided with a stirrup reversing wheel 104. The lower stirrup 108 extends out through the bottom of another set of stirrup coils 110 and the side wire feeding of the stirrup reversing wheel 104.

[0032] The stirrup winding welding system 2 uses its tension adjustment mechanism 204 to apply tension to the upper stirrup 109 and lower stirrup 108. As the rotation drive mechanism 305 on the steel cage rolling system 3 drives the main reinforcement 603 to rotate at a uniform speed, the stirrup winding welding system 2 uses its stirrup welding gun 207 to weld the upper stirrup 109 and lower stirrup 108 evenly and at equal intervals to the outside of the main reinforcement 603 until the steel cage skeleton 6 is formed. The stirrup winding welding system 2 includes a second slide rail 201 and a second slide rail 20... The second slide block 202 is slidably connected to the upper part, the welding machine box 203 is provided at the upper end of the second slide block 202, and the telescopic seat 205 is telescopically provided inside the welding machine box 203. The telescopic seat 205 is provided with two sets of parallel vertical moving rails 209 at one end extending out of the welding machine box 203. The arc-shaped welding claw 206 is slidably connected on the vertical moving rail 209. The stirrup welding gun 207 is fixed in the center on the corresponding arc-shaped welding claw 206, and the upper and lower ends of the arc-shaped welding claw 206 are provided with reserved limiting grooves 208.

[0033] The tension adjustment mechanism 204 includes a tension adjustment box 2041 fixed to the side of the welding machine housing 203, an electric cylinder 2042 fixed inside the tension adjustment box 2041, a movable plate 2043 fixed at the output end of the electric cylinder 2042, two sets of upper and lower sliders 2047 sliding in the slide groove 2048 on the side of the tension adjustment box 2041, and tension wheels 2046 and sliding rods 2045 installed on the outer sides of both ends of the sliders 2047. The sliding rods 2045 slide in the corresponding oblique through grooves 2044 on the movable plate 2043. The two sets of upper tension wheels 2046 are respectively close to the upper stirrup 109 and the lower stirrup 108. The upper stirrup 109 and the lower stirrup 108 extend through the tension adjustment box 2041.

[0034] The tension adjustment mechanism 204 adopts a drive structure of "electric cylinder 2042 + moving plate 2043 + inclined groove 2044 + slider 2047 + tension wheel 2046". The electric cylinder 2042 drives the moving plate 2043 to move. Through the cooperation of the inclined groove 2044 and the sliding rod 2045, the distance between the upper and lower tension wheels 2046 can be adjusted synchronously to achieve synchronous adjustment of the tension of the upper and lower stirrups. The adjustment is precise and efficient, avoiding the stirrups from loosening and causing loose winding or from being too tight and causing the stirrups to break, thus ensuring the forming quality of the spiral stirrup 602.

[0035] The upper stirrup 109 and the lower stirrup 108 are spirally welded to the outside of the main reinforcement 603 to form a spiral stirrup 602. The spiral stirrup 602, the main reinforcement 603 and the annular reinforcing bar 601 are welded to form a steel cage skeleton 6.

[0036] Several sets of bottom support mechanisms 4 for the steel cage are evenly distributed below the steel cage rolling system 3. After the steel cage skeleton 6 is formed, the bottom support mechanism 4 rises and supports the finished steel cage skeleton 6.

[0037] The bottom support mechanism 4 of the steel cage includes a base 401 set inside the support frame 306, a support seat 403 fixed at the upper end of the base 401 by an X-shaped lifting frame 402, and support rollers 404 symmetrically arranged on both sides of the upper end of the support seat 403.

[0038] The main reinforcing bars 603, after being cut to the set length by the automatic rebar shearing machine, are uniformly stored on the main reinforcing bar storage inclined platform 50414 and arranged parallel to the processing axis. After being separated one by one by the material distribution mechanism, they are conveyed to the forming station.

[0039] The main rib welding gun 50408 performs spot welding on the main rib 603 and the annular reinforcing rib 601 according to the preset program.

[0040] The stirrup feeding system 1 is located in the leftmost area. The stirrup coil 110 is stored on the feeding rack in the form of a coil. It is continuously and smoothly led out by the rotation of the turntable 103, and a constant tension is applied by the tension adjustment mechanism 204 on the stirrup winding and welding system 2 to ensure the stability of the stirrups (upper stirrup 109 and lower stirrup 108) during the conveying process, and to provide reliable feeding conditions for the uniform winding of the stirrups.

[0041] The stirrup winding welding system 2 is set on one side of the steel cage rolling system 3. Several sets of main bars 603 and annular reinforcing bars 601 are supported by the rotary drive mechanism 305 and rotate at a constant speed around the processing axis.

[0042] At the same time, the upper stirrup 109 and the lower stirrup 108 are evenly wrapped around the outside of the main reinforcement 603 according to the set pitch.

[0043] When the upper stirrup 109 and the lower stirrup 108 intersect with the main reinforcement 603, the synchronous stirrup welding gun 207 automatically triggers the welding action, so that the stirrup winding and welding processes are completed simultaneously.

[0044] The rotation speed of several sets of main reinforcing bars 603 and annular reinforcing bars 601 are matched with the feeding speed of stirrups to keep the stirrup pitch consistent and ensure the accurate position of the weld points, thereby improving the forming quality of the steel cage skeleton 6.

[0045] The steel cage rolling system 3 is located in the central area of ​​the device.

[0046] The rotary drive mechanism 305 is used to support and stabilize several sets of main ribs 603 and annular reinforcing ribs 601 welded together, ensuring their coaxiality and operational stability during rotary machining.

[0047] The inner shaft rod 3051 and the telescopic cylinder 3052 sleeved on the outside of the inner shaft rod 3051 are telescopically adjustable to adapt to the processing requirements of steel cage skeletons 6 of different lengths.

[0048] After the steel cage frame 6 is formed, the bottom lifting mechanism 4 of the steel cage rises and supports the finished steel cage. The hydraulic cylinder 3053 of the rotary drive mechanism 305 controls the piston rod 3054 to push the arc-shaped concave gripper 3055 to retract inward, so that the steel cage frame 6 gradually separates from the rotary drive mechanism 305. Subsequently, the inner shaft 3051 and the telescopic cylinder 3052 sleeved on the outside of the inner shaft 3051 retract, and the rotary drive mechanisms 305 on the two rotating shafts 304 move away from each other. At the same time, the moving platform 303 moves away from both sides along the third slide rail 301, so that the steel cage frame 6 is completely separated from the whole machine structure. At this time, the finished steel cage can be smoothly transferred to the discharge area by the hoisting equipment.

[0049] Specifically, when using it; (I) Preliminary preparation and positioning of main reinforcement 603 and ring reinforcement 601: 1. Fixing the annular reinforcing rib 601: The annular reinforcing rib 601 is sleeved on the outside of the rotary drive mechanism 305 of the steel cage rolling system 3. The hydraulic cylinder 3053 is started, and the piston rod 3054 at the output end of the hydraulic cylinder 3053 pushes the arc-shaped concave claw 3055 to expand outward until the arc-shaped concave claw 3055 is tightly attached to the inner wall of the annular reinforcing rib 601, thereby achieving the centered fixation of the annular reinforcing rib 601 and providing a reference for the subsequent welding of the main rib 603.

[0050] 2. Feeding and positioning of main reinforcement 603: The main reinforcement feeding and welding system 5 is started. The main reinforcement storage inclined platform 50414 of the main reinforcement storage mechanism 504 is used to stack the main reinforcement 603. The baffle tooth plate 50410 can prevent the main reinforcement 603 from slipping when stacking. The material distribution mechanism starts working. The drive cylinder 50404 drives the moving seat 50403 to move along the guide rod 50402. The moving seat 50403 drives the movable bracket 50405 to move synchronously. The limiting plate 50418 at the top of the movable bracket 50405 pushes the ball 50419 to move. The ball 50419 drives the drive gear 50416 to rotate through the lever 50417. The drive gear 50416 meshes with the driven gear 50415, which in turn drives the rotating rod 50411 to rotate in the bearing seat 50412. The main rib material distribution hook 50413 on the rotating rod 50411 rotates accordingly. The main rib material distribution hook 50413 gradually rotates and approaches the main rib storage inclined platform 50403, causing the main rib 603 on the main rib storage inclined platform 50403 to roll down to the main rib material distribution hook 50413. Subsequently, the drive cylinder 50404 drives the moving seat 50403 to move and reset along the light rod 50402 until the main bar distribution hook 50413 gradually rotates and resets and leaves the main bar storage inclined platform 50403. At this time, the main bar 603 on the main bar distribution hook 50413 will fall down into the main bar guide inclined track 50406, realizing the separation of the main bar 603 one by one. After separation, the main bar 603 limit block 50407 limits the main bar 603, ensuring that the single main bar 603 is accurately delivered to the forming station of the steel cage rolling system 3.

[0051] 3. Axial positioning of main rib 603: The first main rib axial positioning mechanism 502 and the second main rib axial positioning mechanism 503 slide on the fourth slide rail 501 and are adjusted to the position corresponding to the forming station. The first hydraulic support column 5022 extends and retracts to adjust the height of the main control box 5023, and controls the main control box 5023 to drive the hydraulic telescopic shaft 5025 to extend and retract, thereby moving the first main rib axial limiting baffle 5024; the second hydraulic support column 5032 extends and retracts to adjust the height of the second support platform 5035, so that the second main rib axial limiting baffle 5034 corresponds to the first main rib axial limiting baffle 5024. The two cooperate to ensure the axial limiting of the main rib 603 on the crossbeam on several sets of main rib guide inclined rails 50406.

[0052] 4. Subsequently, the drive cylinder 50404 drives the main rib guide inclined rail 50406 to approach the annular reinforcing rib 601 fixed on the rotary drive mechanism 305, and the main rib welding gun 50408 is activated to weld the main rib 603 to the outside of the annular reinforcing rib 601, thus completing the fixed connection between the main rib 603 and the annular reinforcing rib 601.

[0053] (II) Stirrup supply and tension adjustment: The stirrup feeding system 1 provides upper stirrups 109 and lower stirrups 108 to the stirrup winding and welding system 2. Two sets of stirrup rolls 110 are respectively fitted onto the outside of several sets of stirrup fixing brackets 106 on the turntable 103. A ring-shaped support frame 105 is located outside the stirrup rolls 110, providing external protection and limiting the stirrup rolls 110 to prevent them from shifting or loosening during the feeding process. A ring-shaped reinforcing member 107 on the stirrup fixing brackets 106 further fixes the stirrup rolls 110, improving the stability of their placement. The upper stirrup 109 extends directly from the top of the corresponding stirrup roll 110 to the stirrup winding and welding system 2, while the lower stirrup 108 is led out from the bottom of another set of stirrup rolls 110, and after the wire feeding direction is changed by the stirrup reversing wheel 104, it extends to the stirrup winding and welding system 2, achieving synchronous feeding of the upper and lower sets of stirrups.

[0054] The tension adjustment mechanism 204 of the stirrup winding welding system 2 adjusts the tension of the upper and lower stirrups: the electric cylinder 2042 is activated, pushing the moving plate 2043 to move within the tension adjustment box 2041. The inclined groove 2044 on the moving plate 2043 cooperates with the sliding rod 2045, driving the slider 2047 to move up and down within the sliding groove 2048, thereby adjusting the distance between the upper and lower sets of tensioning wheels 2046, so that the tensioning wheels 2046 are in close contact with the upper stirrup 109 and the lower stirrup 108. By adjusting the pressure of the tensioning wheels 2046, the tension of the stirrups is precisely adjusted, avoiding the stirrups from becoming loose or overly tight, which could cause winding deviation.

[0055] (III) Stirrup wrapping and welding: After the stirrup tension is adjusted, the rebar cage rolling system 3 is activated. The inner shaft 3051 of the rotary drive mechanism 305 drives the telescopic cylinder 3052 to rotate. The telescopic cylinder 3052 drives the hydraulic cylinder 3053, the arc-shaped concave gripper 3055, and the annular reinforcing rib 601 and main rib 603 fixed on the outside of the gripper to rotate at a uniform speed. At the same time, the second slide 202 of the stirrup winding welding system 2 moves on the second slide rail 201 to adjust the corresponding position of the stirrup welding gun 207 and the rebar cage forming station. The telescopic seat 205 extends from the welding machine box 203 to adjust the horizontal position of the arc-shaped welding claw 206. The arc-shaped welding claw 206 slides on the vertical moving track 209 to adjust the height of the stirrup welding gun 207 so that the stirrup welding gun 207 is aligned with the junction of the main rib 603 and the stirrup. The reserved limiting groove 208 can temporarily limit the stirrup to ensure that the stirrup and the main rib 603 are tightly fitted.

[0056] As the annular reinforcing rib 601 and the main reinforcing rib 603 rotate at a uniform speed and the stirrups are continuously fed with wire, the stirrup welding gun 207 works synchronously to weld the upper stirrup 109 and the lower stirrup 108 to the outside of the main reinforcing rib 603 in a spiral pattern at equal intervals, forming a spiral stirrup 602. During this process, the two sets of third slide blocks 302 on the third slide rail 301 can drive the moving platform 303, the rotating shaft 304 and the rotating drive mechanism 305 to move synchronously, adjusting the axial position of the reinforcing cage to ensure uniform welding; the support frame 306 between the third slide rails 301 plays a role in supporting and stabilizing the third slide rails 301, preventing the slide rails from deforming and affecting the operation accuracy.

[0057] (iv) Finished product lifting and subsequent processing: After the spiral stirrups 602, main bars 603, and annular reinforcing bars 601 are all welded together to form a complete steel cage skeleton 6, the bottom lifting mechanism 4 of the steel cage is activated. The X-shaped lifting frame 402 on the base 401 extends, driving the lifting seat 403 to rise. The support roller 404 at the upper end of the lifting seat 403 contacts the bottom of the steel cage skeleton 6 and supports the finished product. Then, the hydraulic cylinder 3053 of the rotation drive mechanism 305 retracts, and the arc-shaped concave gripper 3055 separates from the annular reinforcing bar 601, completing the demolding of the finished steel cage, which facilitates subsequent transportation and further processing.

[0058] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
