[0026] The features of the present invention and other related features are further described in detail below through embodiments to facilitate understanding by those skilled in the art:

[0027] In the description, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this case can be understood according to specific circumstances.

[0028] It should be further explained that the words "up" and "down", "left" and "right", "front" and "back" used in the following description refer to directions in the accompanying drawings, and the words "bottom" and "top", "inside" and "outside" respectively refer to directions toward or away from the geometric center of a specific component.

[0029] First, the steel cage to be produced by the processing equipment of this application is explained. The steel cage is an important component in reinforced concrete structures, usually composed of longitudinal steel bars and transverse stirrups, which are used to enhance the bearing capacity and seismic performance of the structure. The longitudinal steel bars mentioned here are the main bars described in this case, and the transverse stirrups are the stirrups to be wound into a rectangular spiral in this case. At the same time, the wound stirrups need to be welded and fixed.

[0030] In modern architecture and civil engineering, steel cages are widely used in various structures such as bridges, tunnels, and high-rise buildings. Among them, the wound rectangular spiral stirrup steel cage has gradually become an efficient and reliable solution due to its unique structural characteristics and excellent mechanical properties.

[0031] This application relates to an integrated device for bending and welding rectangular spiral stirrups. First, its winding is described. Figure 1 The rectangular spiral stirrup winding part of the present application includes a work platform 1, and a first rotating frame 21 and a second rotating frame 22 which are respectively arranged and adjustable at the left and right ends of the work platform 1. The first rotating frame 21 and the second rotating frame 22 determine the side length of the cross section of the spiral stirrup to be wound by adjusting the angle and size of the frame.

[0032] A rotating frame track 13 is provided on the work platform 1, and the first rotating frame 21 and the second rotating frame 22 move left and right on the rotating frame track 13. In this way, longitudinal movement conditions are provided for winding the main reinforcement into rectangular spiral stirrups.

[0033] A rotating spindle 3 is connected between the first rotating frame 21 and the second rotating frame 22. A plurality of main reinforcement fixing frames 23 are arranged on the rotating spindle 3 between the first rotating frame 21 and the second rotating frame 22. The main reinforcement fixing frames 23 are used to fix the longitudinal main reinforcement 100 and improve the rigidity of the steel bar skeleton after forming. At this time, the rotation of the rotating spindle 3 can drive the first rotating frame 21 and the second rotating frame 22 and the plurality of main reinforcement fixing frames 23 to rotate synchronously. In this way, the winding of the spiral stirrups can be realized stably and continuously through the longitudinal movement condition and rotation.

[0034] It should be noted that the rotation of the first rotating frame 21 and the second rotating frame 22 refers to the adjustable part of the main rib 100, not the rotation of the entire rotating frame. Specifically, the first rotating frame 21 and the second rotating frame 22 have a fixed part that moves on the rotating frame track 13 and a rotating part that rotates with the rotating main shaft 3. The application methods of the fixed part and the rotating part are such as bearing type, etc., which will not be described in detail.

[0035] As a device for providing raw material stirrups 200, a winding and forming rectangular spiral stirrup processing equipment of the present application also includes a raw material conveying device 4 for continuously conveying stirrups 200. Specifically, a steel bar raw material roller can be preferably used as the raw material conveying device 4, which can be self-loosened according to needs.

[0036] Furthermore, as described above, the winding position will move with the production progress. In this regard, as a moving device of the raw material conveying device 4, a roller track 41 is also included, and the roller track 41 can move the raw material conveying device 4 left and right, that is, parallel to the rotating frame track 13, and the position of the raw material conveying device 4 can be adjusted according to the operation progress to improve the degree of automation.

[0037] As the winding process progresses, the weight of the steel cage will increase significantly after it is formed. In this regard, the work platform 1 of the present application is divided into fixed platforms 11 arranged at the left and right ends and a transverse platform 12 between the fixed platforms 11. The rotating frame track 13 passes through the fixed platform 11 and the transverse platform 12. By setting up a separate transverse platform 12, it is convenient to replace the finished rectangular spiral stirrup steel cage that has been wound.

[0038] Furthermore, a steel cage support 5 and a longitudinal track for moving the steel cage support 5 left and right are provided at the upper end of the transverse platform 12. Specifically, the steel cage support 5 is of a lifting type. When winding, it is in a descending state, and after the production is completed, it can be in an ascending state to support and lift the finished steel cage. In this way, after the stirrups are wound into a steel cage, the steel cage is supported and lifted, and the position of the steel cage support 5 can be adjusted according to the progress of the operation.

[0039] Furthermore, the present application also includes a bending and welding device 6 for bending and welding the wound stirrups 200. The bending and welding device 6 can move left and right on the rotating frame track 13. Its movement mode is the same as that of the rotating frame, and no detailed description is given for this.

[0040] Furthermore, the raw material conveying device 4 moves synchronously with the bending and welding device 6, so that the stirrups 200 can be cut at an angle perpendicular to the main reinforcement 100, which facilitates bending and welding stability.

[0041] In this way, the bending and welding device 6 in the device can move left and right on the rotating frame track 13, ensuring the flexibility and accuracy of the welding process. This integrated design not only significantly improves production efficiency and reduces errors in manual operation, but also ensures the quality consistency of bending and welding of the stirrups 200, and improves the overall performance and reliability of the product. In addition, the modular design of the device enables it to easily adapt to the production needs of steel cages with stirrups 200 of different specifications, and has wide applicability and good economic benefits.

[0042] The bending and welding device 6 is described in detail below. Figure 2 The bending and welding device 6 includes a movable bracket 61 and a lateral base 62 that moves forward and backward on the movable bracket 61. Figure 3 The welding arm 7 is arranged on the lateral movement base 62 and moves synchronously with the lateral movement base 62. Preferably, the lateral movement base 62 is arranged on the upper end of the mobile bracket 61, and can cover the mobile bracket 61 as a whole at its upper end to improve the lateral movement stability. The welding arm 7 is provided with a retractable welding gun 8. In this way, the welding arm 7 can realize the overall movement in the front-back and left-right directions.

[0043] Specifically, the movable bracket 61 is provided with a hollow ring 63 that is rotatable by the main rib fixing frame 23, and the movable bracket 61 moves on the rotating frame track 13. That is, the main rib 100 is synchronously rotated inside the hollow ring 63, and the whole plays the same role as the first rotating frame 21 and the second rotating frame 22 in the bending rotation.

[0044] In this way, the movement mode thereof is synchronously designed with the first rotating frame 21 and the second rotating frame 22, and no other auxiliary devices need to be added. Meanwhile, the welding is positioned to improve the welding stability.

[0045] For details on the welding arm 7, please refer to Figure 3 Specifically, the welding arm 7 needs to achieve multi-dimensional adjustment to adapt to the precise and synchronous bending and welding of the rotating stirrup 200. In this regard, the welding arm 7 includes a hydraulic telescopic main rod 71 that can move up and down, driving the telescopic welding gun 8 to move up and down.

[0046] Further, on this basis, the welding arm 7 also includes a rotating hinge 72 arranged between the hydraulic telescopic main rod 71 and the telescopic welding gun 8 and driving the telescopic welding gun 8 to rotate forward and backward. Figure 1 and Figure 2 .

[0047] The rotating hinge 72 is a connecting component used to realize the rotation and movement of the telescopic welding gun 8 within a certain range. It consists of a central axis 73 and two first adjustable hydraulic rods 74 arranged in front and behind. In this way, the angle of the telescopic welding gun 8 and the degree of fit between the rectangular spiral stirrup 200 and the longitudinal main reinforcement 100 during the rotating winding process can be adjusted by the extension and retraction of the first adjustable hydraulic rod 74.

[0048] Furthermore, the welding arm 7 further comprises a welding gun bracket 75 connected to the lower end of the rotating hinge 72, and a first transverse roller shaft 76 and a plurality of second transverse roller shafts 77 are provided at the lower end of the welding gun bracket 75, that is, on the opposite side of the rotating hinge 72, and the retractable welding gun 8 is connected to the first transverse roller shaft 76, and the second transverse roller shaft 77 is connected to the stirrup bending adapter roller shaft 78. The stirrup bending adapter roller shaft 78 abuts against the stirrup 200, and preferably, the number of the second transverse roller shafts 77 is two, which are respectively arranged at the front and rear ends of the first transverse roller shaft 76.

[0049] In this way, the first transverse roller 76 is used for moving the telescopic welding gun 8, and the second transverse roller 77 is used for moving the stirrup bending adapter roller 78. The stirrup bending adapter roller 78 is used for bending the stirrups 200 at the corners and guiding the telescopic welding gun 8 out of the straight section.

[0050] Preferably, the stirrup bending adapter roller 78 is connected to the second transverse roller 77 through a second adjustable hydraulic rod 79. In this way, the stirrup 200 can be bent by adjusting the contact with the stirrup 200 through the telescopic adjustment of the second adjustable hydraulic rod 79, so that the welding of the telescopic welding gun 8 is more stable.

[0051] The following is an explanation of the application example of the welding arm 7. Figure 4 In application example 1, when the stirrup 200 is in a bent state, the second adjustable hydraulic rod 79 at the bending position thereof is extended, contacts the stirrup 200, and bends the stirrup 200, and the second adjustable hydraulic rod 79 on the opposite side contracts accordingly, thereby keeping the retractable welding gun 8 in a stable abutment state, thereby ensuring the bending and welding effects.

[0052] Please refer to Figure 5 In the second application example, when the stirrup 200 is in an inclined state, the hinge 72 is rotated along the inclined direction to make a rotation adjustment. Specifically, the first adjustable hydraulic rod 74 is extended and contracted to adjust the angle of the welding gun bracket 75 to adapt to the angle change of the stirrup 200. At this time, the stirrup bending adaptation roller 78 and the retractable welding gun 8 are both in contact with the stirrup 200, thereby ensuring the welding effect.

[0053] As mentioned above, this case protects an integrated device for bending and welding rectangular spiral stirrups. All technical solutions that are the same or similar to this case should be deemed to fall within the scope of protection of this case.
