[0051] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that for the convenience of description, only the parts related to the present utility model are shown in the drawings rather than all the structures.

[0054] In the description of this embodiment, the terms "upper", "lower", "right", etc., which refer to the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings. They are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0055] As Figure 7 shown, the stirrup 200 of the prior art is formed by bending a long steel bar, and it can cooperate with Figure 12 the single-piece net 100 shown to form the steel cage of the shield segment. The stirrup 200 includes two long sides and a closed short side between the two long sides respectively.

[0056] As Figures 3 to 12 shown, the present utility model provides a stirrup automatic forming, stacking and welding device 10, which includes a frame 1, a feeding and fixing mechanism 2, a bending mechanism 3, a spreading and stacking mechanism 4 and a welding mechanism 5. The feeding and fixing mechanism 2 is arranged on the frame 1, and the feeding and fixing mechanism 2 can loosen or fix the steel bar; at least two bending mechanisms 3 are movably arranged on the frame 1 along the fixing direction of the steel bar, and the bending mechanism 3 can bend the steel bar fixed by the feeding and fixing mechanism 2 to form the stirrup 200; the spreading and stacking mechanism 4 is arranged on the frame 1, and the spreading and stacking mechanism 4 is used to receive the stirrup 200 and spread it out and place it on the single-piece net 100; the welding mechanism 5 can weld the stirrup 200 and the single-piece net 100.

[0057] By using the above device, the steel bar can be fixed on the feeding and fixing mechanism 2, and then the steel bar is bent into the stirrup 200 by the bending mechanism 3. Then, the stirrup 200 is spread out by the spreading and stacking mechanism 4 and placed on the single-piece net 100. Subsequently, the overlapping points between the stirrup 200 and the single-piece net 100 are welded by the welding mechanism 5. The above device can complete the bending, forming, spreading, stacking and welding of the stirrup 200 at one time without manual insertion, with a high degree of automation and improved production efficiency.

[0058] As Figure 3As shown, in some embodiments, the loading and fixing mechanism 2 includes a conveying assembly 21 and a receiving assembly 22, wherein the conveying assembly 21 includes a conveyor belt 212 and a guide plate 211. The conveyor belt 212 is used to convey steel bars. The conveyor belt 212 and the guide plate 211 are fixed to the above-mentioned frame 1. The guide plate 211 is set downstream of the conveyor belt 212, and the guide plate 211 is tilted on the frame 1, so that when the conveyor belt 212 conveys the steel bars to the guide plate 211, the steel bars can slide down along the guide plate 211. It is understandable that the conveyor belt 212 can also be replaced by a conveyor roller. Furthermore, in order to ensure the stability of the downward movement, limiting plates can be set on both sides of the guide plate 211 to prevent the steel bars from sliding out from the side of the guide plate 211.

[0059] In addition, the material receiving assembly 22 includes a supporting drive member 221 and a supporting plate 222. The supporting plate 222 is connected to the downstream of the guide plate 211 through a rotating shaft, and the output end of the supporting drive member 221 is connected to the supporting plate 222, thereby driving the supporting plate 222 to rotate, which is equivalent to the guide plate 211, and then the supporting plate 222 is set at an angle with the guide plate 211, so as to support the steel bars that slide down from the guide plate 211. For example, the supporting drive member 221 can be but is not limited to being driven by a cylinder. Furthermore, in order to ensure the stability of the support, a supporting groove is provided on the supporting plate 222, and the steel bars are limited to the above-mentioned supporting groove. Furthermore, since the steel bars have a certain length, in the current embodiment, the material receiving assembly 22 is arranged in multiple groups at intervals along the fixed direction of the steel bars. It should be noted that the fixed direction of the steel bars referred to in the current embodiment is the fixed direction of the steel bars on the supporting plate 222.

[0060] like Figure 7 As shown, it should be noted that since the straight steel bar needs to be bent four times to form the stirrup 200, in the current embodiment, at least two bending mechanisms 3 are provided. The two bending mechanisms 3 can move along a fixed direction of the steel bar, thereby performing two simultaneous bends at each end of the straight steel bar. In other embodiments, four bending mechanisms 3 can be directly and movably provided on the frame 1, with two bending mechanisms 3 first bending the two outer bending points, and then the other two bending mechanisms 3 bending the two middle bending points.

[0061] Specifically, the bending mechanisms 3 are all arranged on the frame 1 in a movable manner along the fixed direction of the steel bar, so that the position of the bending point can be adjusted. In the current embodiment, the bending mechanisms 3 are arranged above the supporting plate 222, and each bending mechanism 3 includes a connecting seat 31. The frame 1 is provided with a guide rail, and the connecting seat 31 is movably arranged on the guide rail; specifically, as shown in FIG. Figure 4As shown, the frame 1 is provided with a travel drive 313, which drives the connecting base 31 to travel on the guide rail. For example, the travel drive 313 can be a linear drive such as a screw motor or a cylinder. The connecting base 31 is provided with a lifting drive 32. The output end of the lifting drive 32 is provided with a bending fixed base 33. The bending fixed base 33 is provided with a central axis 34 and a bending drive 35. The output end of the bending drive 35 is provided with a bending axis 36. A gap is provided between the bending axis 36 and the central axis 34, so that the steel bar can be clamped therebetween. The bending drive 35 can drive the bending axis 36 to rotate around the central axis 34, thereby horizontally bending the steel bar in a fixed direction perpendicular to the steel bar, and then forming the stirrup 200 through multiple bending. It should be noted that, since there are multiple material receiving components 22, the bending mechanism 3 is bent by the two ends of the steel bar, wherein the support plate 222 between the point where the steel bar needs to be bent and the end of the steel bar is driven to separate from the steel bar by the support drive 221 when bending, completing the avoidance and avoiding bending interference. In other words, when bending is required, the central axis 34 and the bending axis 36 are first driven down by the lifting drive 32 so that the steel bar is located between the central axis 34 and the bending axis 36, and then the outer support plate 222 leaves the steel bar to avoid, and then the bending drive 35 drives the bending axis 36 to rotate for bending. For example, the lifting drive 32 adopts a cylinder. In order to ensure the stability of the lifting and lowering of the bending fixed seat 33, a lifting guide shaft 37 is also provided on the connecting seat 31, and the bending fixed seat 33 is inserted into the lifting guide shaft 37 and lifted and lowered along the lifting guide shaft 37.

[0062] In the current embodiment, the bending actuator 35 is a pneumatic cylinder. This means that during bending, the cylinder's linear motion must be converted into circular motion about the central axis 34. Therefore, the bending mount 33 is provided with a bending fixed shaft 38 and a bending arm 39. The central axis 34 is coaxially disposed below the bending fixed shaft 38. The bending arm 39 is rotatably mounted on the bending fixed shaft 38. The bending arm 39 has two extended cantilevered ends, which are arranged at an angle. The bending shaft 36 is fixed to one of the cantilevered ends, while the output end of the bending actuator 35 is fixed to the other cantilevered end. Consequently, when the output end of the bending actuator 35 undergoes linear motion, the bending shaft 36 is driven to rotate about the central axis 34 via the bending arm 39. Furthermore, to prevent jamming, a rotating mount is connected to the bending mount 33. The bending actuator 35 is mounted on the rotating mount. This allows the bending actuator 35 to deflect during operation, preventing jamming. It is understood that the bending actuator 35 could also be a motor.

[0063] like Figure 7As shown, after the bending point on the outermost side of the steel bar is bent, the bending driving member 35 drives the bending shaft 36 to reset. Subsequently, the lifting driving member 32 needs to drive the bending shaft 36 and the central shaft 34 to rise away from the steel bar, and then the bending mechanism 3 moves to the next bending point. Since after the bending driving member 35 drives the bending shaft 36 to reset, the central shaft 34 and the bending shaft 36 are still in a position relatively close to the bending point. At this time, when driving the two to rise, the central shaft 34 and the bending shaft 36 are likely to lift the steel bar. To avoid the above phenomenon, as Figure 4 shown, a dodging driving member 310 is further provided on the connecting seat 31. The output end of the dodging driving member 310 is provided with a lifting seat 311. The lifting driving member 32 is arranged at the output end of the dodging driving member 310. The dodging driving member 310 can drive the bending shaft 36 and the central shaft 34 to move along the moving direction of the bending mechanism 3. That is to say, it can drive the central shaft 34 and the bending shaft 36 to move along the direction in which the steel bar is fixed, so as to make the central shaft 34 and the bending shaft 36 away from the bending point, and then the lifting driving member 32 drives the two to rise. Further, to ensure the stability of the movement, a transverse guiding shaft 312 is provided on the lifting seat 311, and the lifting seat 311 is sleeved on the transverse guiding shaft 312. Exemplarily, the dodging driving member 310 is a cylinder. It can be understood that the dodging driving member 310 can also be a motor.

[0064] After the stirrup 200 is bent, it can be removed from the supporting plate 2 by the above-mentioned spreading and stacking mechanism 4, and is spread and placed on the single-layer mesh 100. Based on this, as Figures 8 to 12 shown, the spreading and stacking mechanism 4 includes a fixing frame 41, a rotating support rod 42 and a spreading driving member 45. The fixing frame 41 is movably arranged on the frame 1; the first ends of the two rotating support rods are rotatably connected to the fixing frame 41 at intervals. The second ends of the two rotating support rods extend away from the fixing frame 41. A fixing portion is provided on each rotating support rod for fixing two opposite long sides on the stirrup 200; the output end of the spreading driving member 45 is at least connected to one of the rotating support rods to drive the second ends of the two rotating support rods to approach or move away from each other.

[0065] Furthermore, the two opposite long sides on the stirrup 200 are fixed by the fixing portions provided on the rotating support rods. Then, after the supporting plate 222 is separated from the stirrup 200, the spreading driving member 45 drives the second ends of the two rotating support rods to move away, so that the stirrup 200 can be spread and placed on the single-layer mesh 100. Subsequently, the second ends of the rotating support rods are driven to approach, so that the stirrup 200 is restored to its original state, and thus the stirrup 200 is placed on the single-layer mesh 100.

[0066] In some embodiments, the fixing frame 41 is disposed on the lower side of the supporting plate 222. When the stirrup 200 is clamped by the spreading and stacking mechanism 4, it is necessary to make the direction of the rotating support rod 42 consistent with the long side direction of the stirrup 200. The long side of the stirrup 200 is in the horizontal direction, and the stirrup 200 needs to be opened in the vertical state and then placed on the single-layer mesh 100. Based on this, in the current embodiment, the fixing frame 41 can be flipped relative to the machine frame 1. Specifically, the spreading and stacking mechanism 4 further includes a flipping driving member 44. The flipping driving member 44 is disposed on the machine frame 1, and the fixing frame 41 is disposed at the output end of the flipping driving member 44. Then, the fixing frame 41 is driven to flip by the flipping driving member 44, so that the rotating support rod 42 receives the stirrup 200 in the horizontal state. Subsequently, after the rotating support rod 42 is flipped downward to the vertical state, the stirrup 200 can be opened in the vertical state and then placed on the single-layer mesh 100, making the placement more convenient. Specifically, the flipping driving member 44 is a rotating motor. A rotating shaft 441 is disposed at the output end of the rotating motor. The fixing frame 41 is fixed to the rotating shaft 441 by welding or bolts. Then, driven by the rotating motor, the fixing frame 41 is flipped relative to the machine frame 1 to perform the operations of taking and placing the stirrup 200.

[0067] As Figure 11 shown, in some embodiments, in order to facilitate fixing the long side of the stirrup 200, the fixing portion 43 includes a limiting block 431 and a fixing driving member 432. A plurality of limiting blocks 431 are arranged at intervals along the length direction of the rotating support rod 42. The limiting blocks 431 are L-shaped. Each limiting block 431 corresponds to a fixing driving member 432. The fixing driving member 432 is disposed opposite to the limiting block 431. A clamping plate 433 is disposed at the output end of the fixing driving member 432. The fixing driving member 432 can drive the clamping plate 433 to approach or move away from the limiting block 431 so as to clamp or release the long side of the stirrup 200. Further, in order to ensure the stability of clamping, a limiting notch 434 is provided on the surface of the limiting block 431 facing the clamping plate 433 and / or on the side of the clamping plate 433 facing the limiting block 431. Thus, when the limiting block 431 contacts the clamping plate 433, a limiting space is formed to limit the stirrup 200 therein.

[0068] As Figure 8 、 Figure 9 and Figure 12As shown, in some embodiments, an expansion drive member 45 is disposed on a fixed frame 41, and a rotating plate 46 is disposed at the output end of the expansion drive member 45. The expansion drive member 45 drives the rotating plate 46 to rotate. The two ends of the rotating plate 46 are respectively rotatably connected to one end of two first connecting plates 47, and the other ends of the two first connecting plates 47 are rotatably connected to one end of two second connecting plates 48. The other ends of the two second connecting plates 48 are respectively connected to the first ends of the two rotating support rods 42, and the middle portion of the second connecting plate 48 is connected to the fixed frame 41, thereby forming a connecting rod group through the first connecting plate 47 and the second connecting plate 48, and then the rotation of the rotating plate 46 drives the expansion or closing of the rotating support rods 42. For example, the expansion drive member 45 can be, but is not limited to, a rotary cylinder or a rotary motor. The above method can achieve the opening and closing of the second end of the rotating support rod 42 by controlling the first end of the rotating support rod 42, thereby avoiding unnecessary interference caused by the stirrups 200 when receiving or placing the stirrups 200. At the same time, the above structure can also minimize the opening angle of the first end of the rotating support rod 42 to avoid affecting the short side of the stirrups 200. It is understood that in other alternative embodiments, the connecting rod group formed by the first connecting plate 47 and the second connecting plate 48 can also be replaced by other methods such as chain drive, gear drive, or belt drive.

[0069] In some embodiments, in order to facilitate the stacking of the stirrups 200 onto the single-sheet net 100 and to ensure the stability of the stirrups 200 during the flipping of the fixing frame 41 and the placement of the stirrups 200, the stacking mechanism 4 further includes a telescopic drive member 49, which is arranged on the fixing frame 41 and is located between the first ends of the two rotating support rods 42. A card seat 491 is provided at the output end of the telescopic drive member 49, and a card slot 492 is provided on the card seat 491. The slot direction of the card slot 492 is aligned with the direction of the rotating support rod 42. The rod 42 extends in a vertical direction, and the clamping seat 491 can be clamped to the short side of the stirrup 200 through the clamping slot 492. The telescopic drive member 49 can drive the clamping seat 491 toward or away from the second end of the rotating support rod 42. Therefore, when the stirrup 200 is opened and placed on the single-piece net 100, the telescopic drive member 49 drives the clamping seat 491 toward the second end of the rotating support rod 42, thereby causing the stirrup 200 to slide along the rotating support rod 42, thereby completely fitting the stirrup 200 to the single-piece net 100, and then performing the welding operation. For example, the telescopic drive member 49 can be, but is not limited to, a cylinder or a motor.

[0070] like Figure 8 and Figure 9As shown, in some embodiments, the spreading and stacking mechanism 4 also includes a rotating drive member 4100, which is arranged on the frame 1, and a rotating plate 4101 is provided at the output end of the rotating drive member 4100. The rotating drive member 4100 drives the rotating plate 4101 to rotate relative to the frame 1, and the flipping drive member 44 is provided on the rotating plate 4101, and then the angle of the rotating support rod 42 is adjusted by the rotation of the rotating plate 4101, and then the stacking angle of the stirrups 200 is adjusted to adapt to the single-piece net 100 in different positions.

[0071] like Figure 1 As shown, in some embodiments, the welding mechanism 5 includes a robotic arm and a welding head disposed on the robotic arm. In the current embodiment, two sets of welding mechanisms 5 are provided, spaced apart on the frame 1 and located on both sides of the support and stacking mechanism 4, thereby facilitating welding of the overlapped joints between the stirrups 200 and the single-piece mesh 100. Furthermore, the stirrup automatic forming, stacking and welding equipment 10 may also include a visual inspection mechanism (not shown in the figure), which includes but is not limited to a camera, thereby completing the welding of the overlapped joints between the stirrups 200 and the single-piece mesh 100 through visual inspection technology.

[0072] like Figure 1 and Figure 2 As shown, the utility model also provides a shield segment reinforcement cage production system, which includes a workbench 20, a grabbing device 40 and the above-mentioned stirrup automatic forming, stacking and welding equipment 10. The workbench 20 is provided with a plurality of single-piece mesh molds 30 along its circumference, and the single-piece mesh mold 30 is configured to place the single-piece mesh 100; the grabbing device 40 rotates relative to the workbench 20, and the grabbing device 40 can place the single-piece mesh 100 in the single-piece mesh mold 30; the frame 1 of the stirrup automatic forming, stacking and welding equipment 10 is transferred to the workbench 20, and the stirrup automatic forming, stacking and welding equipment 10 can bend the steel bars into stirrups 200 and weld them to the single-piece mesh 100.

[0073] The single-piece mesh 100 is placed in the single-piece mesh mold 30 at different positions on the workbench 20 through the grabbing device 40, and then the stirrups are automatically formed and stacked by the stirrup welding device 10. The stirrups are automatically formed and stacked by the welding device 10. The steel bars can be bent into stirrups 200 and welded to the single-piece mesh 100. During the process, there is no need for manual placement of stirrups and welding, the degree of automation is high, and production efficiency is improved.

[0074] like Figure 1As shown, in some embodiments, a main shaft 201 is provided on the workbench 20, and multiple single-piece mesh molds 30 are distributed circumferentially along the main shaft 201, and each single-piece mesh mold 30 needs to hold multiple single-piece meshes 100. Therefore, the grasping device 40 includes a grasping arm, the first end of which is rotatably connected to the main shaft 201, the second end of which extends away from the workbench 20, and a gripper is movably provided on the grasping arm, so that the multiple single-piece meshes 100 can be moved into the single-piece mesh mold 30 on the workbench 20 by the gripper. In order to ensure the stability of the grasping arm, a first curved rail is provided on the outer periphery of the workbench 20, and the grasping arm is movably provided on the first curved rail. For example, the form of the gripper is not specifically limited.

[0075] In some embodiments, the first end of the frame 1 is also connected to the main shaft 201, and the second end of the frame 1 extends away from the workbench 20. In order to ensure the stability of the frame 1, a second arc rail is provided on the periphery of the workbench 20, and the second end of the frame 1 is moved and set on the second arc rail. Then, through the movement of the frame 1, multiple stirrups 200 can be placed at intervals on the single-piece net 100.

[0076] Furthermore, in order to reduce the floor space and avoid excessive rotation range of the frame 1 and the grabbing arm, in some embodiments, the workbench 20 can rotate, thereby moving the single-piece mesh mold 30 at different positions to the grabbing device 40 or the stirrup automatic forming and stacking welding equipment 10.

[0077] The following is a brief description of the entire production process:

[0078] The grabbing device 40 places the produced multiple single-piece meshes 100 in the single-piece mesh mold 30 on the workbench 20, and then the workbench 20 rotates to move the single-piece mesh mold 30 with the single-piece meshes 100 placed thereon to the stirrup automatic forming, stacking and welding device 10;

[0079] The straight steel bar is placed on the conveyor belt 212 of the feeding fixing mechanism 2 for transmission and is moved to the supporting plate 222 for support through the guide plate 211. The bending mechanism 3 moves to the outermost bending point (taking two bending mechanisms 3 as an example), and the lifting drive member 32 drives the bending shaft 36 and the center shaft 34 to descend to the steel bar, and the bending drive member 35 drives the bending shaft 36 to move. It should be noted that before the bending drive member 35 drives the bending shaft 36, the supporting drive member 221 drives the supporting plate 222 to complete the avoidance, and then completes the outermost bending, and then the bending drive member 35 drives the bending shaft 36 to reset; then, the avoidance drive member 310 drives the center shaft 34 and the bending shaft 36 to move away from the above-mentioned bending point along the fixed direction of the steel bar, and then the lifting drive member 32 drives the bending shaft 36 and the center shaft 34 to rise and reset, and then the two bending mechanisms 3 move to the next bending point, and the bending operation is repeated again until the stirrup 200 is bent;

[0080] Subsequently, the flipping drive member 44 of the spreading and stacking mechanism 4 drives the rotating support rod 42 to flip upward, causing the two long sides of the stirrup 200 to fall onto the two rotating support rods 42, and the short side to fall into the card slot 492 of the card seat 491. Subsequently, the fixing drive member 432 drives the clamping plate 433 and the limiting block 431 to clamp the above-mentioned stirrup 200, and all the supporting plates 222 are separated from the stirrup 200. Then, the flipping drive member 44 drives the rotating support rod 42 to flip downward. When the stirrup 200 is directly above the single-layer mesh 100, the placement angle can be adjusted by driving the rotating drive member 4100 during this period. The spreading drive member 45 drives the rotating support rod 42 to drive the stirrup 200 to spread. Subsequently, the telescopic drive member 49 drives the card seat 491 to drive the stirrup 200 to move downward to fit with the single-layer mesh 100. After the spreading drive member 45 drives the rotating support rod 42 to drive the stirrup 200 to close, the welding mechanism 5 performs welding. After the welding is completed, the fixing drive member 432 drives the clamping plate 433 to separate from the limiting block 431. Then, the flipping drive member 44 drives the fixing frame 41 to flip reversely, disengaging from the stirrup 200 and performing the welding of the next stirrup 200 until all the stirrups 200 on the positioning net mold are welded to form the shield segment steel reinforcement cage. Subsequently, the workbench 20 rotates to move the welded shield segment steel reinforcement cage out of the stirrup automatic forming, stacking and welding equipment 10.
