In the existing technology, when producing a single piece of T-beam reinforcement skeleton, the long stirrups and horseshoe bars are generally bent and processed separately, and then manually transported to the platform for stacking and binding. This not only results in low production efficiency, but also disperses the work area and occupies a large space. Utility Model Content

[0050] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0054] refer to Figures 1-14As shown in this embodiment, a single-piece production line for the web skeleton of a T-beam is proposed, including a feeding device 200, a horseshoe-shaped reinforcement bending device 300, a long stirrup bending device 400, a welding device 100, a cantilever crane 600, and a unloading device 700. The horseshoe-shaped reinforcement bending device 300 and the long stirrup bending device 400 are arranged along a first direction. The horseshoe-shaped reinforcement bending device 300 is used for forming horseshoe-shaped reinforcement, and the long stirrup bending device 400 is used for forming long stirrups. The feeding device 200 and the welding device 100 are respectively arranged on opposite sides of the horseshoe-shaped reinforcement bending device 300 and the long stirrup bending device 400 along a second direction. There are two feeding devices 200 along the first direction, one of which is used to deliver the steel bars to the horseshoe-shaped reinforcement along the second direction. A bending device 300, another for delivering the reinforcing bars to the long stirrup bending device 400 along the second direction, a welding device 100 for welding the horseshoe-shaped reinforcing bars and the long stirrups, a cantilever crane 600 is set on the side of the welding device 100 away from the feeding device 200, and two cantilever cranes 600 are also set along the first direction, one cantilever crane 600 is used to deliver the horseshoe-shaped reinforcing bars to the welding device 100 along the second direction, and the other cantilever crane 600 is used to deliver the long stirrups to the welding device 100 along the second direction, and a unloading device 700 is set between the two cantilever cranes 600 for removing the formed T-beam web skeleton piece from the welding device 100. The first direction and the second direction are two mutually perpendicular directions on the horizontal plane.

[0055] The aforementioned T-beam web skeleton production line can automatically feed, bend, weld and unload the production process of T-beam web skeleton (hereinafter referred to as skeleton 10). It has a high degree of automation, can achieve continuous production, and has a concentrated working area with a small footprint.

[0056] refer to Figure 2 As shown, the welding device 100 includes a base 110, a welding mechanism 120, and a traveling mechanism. The base 110 is mounted on the traveling mechanism, and the welding mechanism is mounted on the base. The traveling mechanism is used to drive the base 110 to move along a first direction. The base 110 is provided with a plurality of positioning slots 113, and the positioning slots 113 are provided with a plurality of upward-facing positioning slots for positioning the horseshoe-shaped reinforcement 11 and the long stirrups. The welding mechanism 120 is mounted on the base 110 for welding and fixing the horseshoe-shaped reinforcement 11 and the long stirrups.

[0057] refer to Figure 15As shown, the horseshoe-shaped reinforcing bar 11 and the long stirrup constituting the skeleton piece 10 include a first coincident point located at the first end of the long stirrup along its length direction, and a second coincident point and a third coincident point located on opposite sides of the long stirrup along its width direction and symmetrically arranged. To ensure a stable connection between the horseshoe-shaped reinforcing bar 11 and the long stirrup, welding fixation is required at the first coincident point, the second coincident point, and the third coincident point. That is, the first coincident point is the first welding point A, the second coincident point is the second welding point B, and the third coincident point is the third welding point C. Based on this, the welding mechanism 120 includes a first welding mechanism 120a and a second welding mechanism 120b. The first welding mechanism 120a includes a first welding component for welding fixation of the first welding point A, and the second welding mechanism 120b includes two sets of second welding components symmetrically arranged along a second direction, respectively used for welding fixation of the second welding point B and the third welding point C. To avoid obstruction when placing the horseshoe-shaped reinforcement 11 and the long stirrups in the positioning slot 113, the first welding component in the first welding mechanism 120a is slidably disposed on the platform 110 along a first direction. The first welding mechanism 120a includes a first driving member 125 that drives the first welding component to move along the first direction. Two sets of second welding components in the second welding mechanism 120b are slidably disposed on the platform 110 along a second direction. The second welding mechanism 120b includes a second driving member 126 that drives the two sets of second welding components to move towards or away from each other along the second direction. The first direction is the length direction of the long stirrups. Figure 1 The first direction is the X-axis direction), and the second direction is the width direction of the long stirrup ( ). Figure 1 (In the Y-axis direction), that is, the first direction and the second direction are perpendicular to each other.

[0058] Continue to refer to Figure 15 As shown, the long stirrups constituting the skeleton piece 10 are formed by bending steel bars. The long stirrups include a connecting section 12, an extension section 13, and a bent section 14. The connecting section 12 is U-shaped, and two extension sections 13 are respectively connected to the two ends of the connecting section 12. The two bent sections 14 are formed by bending the two extension sections 13 towards each other. In order to maintain the stability of the shape of the long stirrup, the two bent sections 14 also need to be connected and fixed. Therefore, the skeleton piece 10 also includes a fourth welding point D located at the end of the long stirrup away from the first welding point A. Based on this, the welding mechanism 120 also includes a third welding mechanism 120c. The third welding mechanism 120c includes a third welding component that is slidably disposed on the base 110 along the first direction. At the same time, the third welding mechanism 120c also includes a third driving member 127 for driving the third welding component to move along the first direction, and the second welding mechanism 120b is located between the first welding mechanism 120a and the third welding mechanism 120c.

[0059] Since the two bent sections 14 of the long stirrup are not fixed, due to the elasticity of the long stirrup itself, the initial distance between the two extended sections 13 of the long stirrup placed on the positioning slot 113 along the second direction is greater than the preset distance. On this basis, the welding device 100 also includes a first clamping mechanism 130 located between the second welding mechanism 120b and the third welding mechanism 120c. The first clamping mechanism 130 includes two clamping components 131 that are slidably arranged at intervals along the second direction and a fourth driving member 132 for driving the two clamping components 131 to move towards or away from each other along the second direction. The two clamping components 131 are respectively used to clamp the two extended sections 13 and drive the two extended sections 13 to move along the second direction so that the two extended sections 13 are close to each other to a preset distance.

[0060] The aforementioned welding device 100 uses the first clamping mechanism 130 in conjunction with the positioning slot 113 on the base 110 to position the horseshoe tendon 11 and the long stirrup. At the same time, the welding mechanism 120, which is movably set on the base 110, is used to weld each welding point of the horseshoe tendon 11 and the long stirrup, thereby realizing the automatic welding of the single piece 10 of the skeleton, with high forming accuracy and production efficiency.

[0061] refer to Figure 3 As shown, the positioning slot seats 113 are arranged in pairs to form positioning slot seat groups. The platform 110 includes three positioning slot seat groups, two of which are used to support and position the horseshoe-shaped reinforcement 11, and the other group is used to support and position the long stirrups. Specifically, for ease of description, the two positioning slot seat groups used to support and position the horseshoe-shaped reinforcement 11 are defined as the first positioning slot seat group and the second positioning slot seat group, respectively. The positioning slot seat group used to support and position the long stirrups is defined as the third positioning slot seat group. The positioning slots provided on the positioning slot seats 113 in the first positioning slot seat group and the third positioning slot seat group all penetrate the positioning slot seats 113 along the first direction, while the positioning slots provided on the two positioning slot seats 113 in the second positioning slot seat group penetrate the positioning slot seats 113 along the second direction.

[0062] More specifically, in order to reduce the difficulty of the horseshoe-shaped reinforcement 11 and the long stirrup entering the positioning slot, the opening of the positioning slot is set as a trumpet shape that gradually narrows from top to bottom.

[0063] refer to Figure 2 As shown, the pedestal 110 includes a frame 111 and a panel 112. The panel 112 is fixed to the outer surface of the frame 111, and the panel 112 is provided with a clearance opening for the welding mechanism 120 and the first clamping mechanism 130 to pass through. The positioning slot 113 is embedded in the top surface of the panel 112, and the bottom of the positioning slot on the positioning slot 113 is flush with the top surface of the panel 112. When the horseshoe-shaped reinforcement 11 and the long stirrup are placed in the positioning slot 113, the pedestal 110 can cooperate with the positioning slot 113 to support the horseshoe-shaped reinforcement 11 and the long stirrup, reducing the possibility of deformation of the horseshoe-shaped reinforcement 11 and the long stirrup due to gravity.

[0064] refer to Figure 6 and Figure 7 As shown, the clamping assembly 131 includes a mounting base plate 1313, two clamping plates 1311 spaced apart along a second direction, and a fifth driving member 1312. Both clamping plates 1311 are disposed on the mounting base plate 1313, and at least one clamping plate 1311 is connected to the fifth driving member 1312. The fifth driving member 1312 is configured to drive the clamping plates 1311 to reciprocate along the second direction to clamp or release the long stirrups.

[0065] For example, the fifth drive member 1312 is a cylinder, and in order to use the same fourth drive member 132 to make the two clamping assemblies 131 move towards or away from each other, the first clamping mechanism 130 also includes a flexible transmission structure. The fourth drive member 132 is a motor, and the motor is connected to the two clamping assemblies 131 through the flexible transmission structure. Specifically, the flexible transmission structure includes sprockets and a chain. The chain is wound between two sprockets spaced apart along the second direction. One of the sprockets is connected to the fourth drive member 132. The two clamping assemblies 131 are respectively mounted on the upper and lower layers of the chain through clamping plates, thereby realizing opposite or opposite movements under the drive of the motor. In order to enable the clamping plate 1311 to protrude from the panel 112, the first clamping mechanism 130 also includes a support frame 133. The clamping component 131 is slidably disposed on the support frame 133 along the second direction. The support frame 133 is also provided with a positioning guide rail to guide the movement direction of the clamping component 131. The clamping component 131 is slidably connected to the support frame 133 through the positioning guide rail.

[0066] refer to Figures 8-14 As shown, the first welding assembly, the second welding assembly, and the third welding assembly each include an upper electrode 122, a lower electrode 123, and a sixth driving member 124. The first welding assembly, the second welding assembly, and the third welding assembly are each slidably mounted on the platform 110 via a sliding base plate 121. The upper electrode 122 and the lower electrode 123 are arranged vertically on the sliding base plate 121 at intervals. The sixth driving member 124 is connected to the lower electrode 123 to drive the lower electrode 123 to rise and fall, so that the lower electrode 123 cooperates with the upper electrode 122 to clamp the reinforcing bar and weld the reinforcing bar.

[0067] For example, the first drive member 125 and the sixth drive member 124 are both cylinders, and the third drive member 127 is a motor. A rack is provided on the base 110, and the motor, which serves as the third drive member 127, is provided with a gear that meshes with the rack. When the motor rotates, the gear meshing with the rack drives the third welding assembly to move along the first direction. The second drive member 126 is also a motor, and the motor, in conjunction with the flexible transmission structure, drives the two second welding assemblies. It should be emphasized that, in order to achieve synchronous opposite and backward movement of the two second welding assemblies along the second direction, the two second welding assemblies are respectively arranged on the upper and lower layers of the flexible element (e.g., chain) in the flexible transmission structure.

[0068] In order to enable the upper electrode 122 to fit with the steel bar, the first welding mechanism 120a, the second welding mechanism 120b and the third welding mechanism 120c all include a seventh driving member 128. Multiple seventh driving members 128 can drive their respective first welding components, second welding components and third welding components to rise and fall.

[0069] To accommodate the welding of single-piece skeletons of different lengths, the second welding mechanism 120b further includes an eighth drive member 129, which is configured to drive the second welding assembly to move along a first direction. Specifically, the second welding mechanism 120b also includes a translation base, which is slidably mounted on the platform 110 along the first direction. The sliding base plate 121 of the second welding mechanism 120b is mounted on the translation base, and under the drive of the eighth drive member 129, the sliding base plate 121 moves along the first direction together with the translation base.

[0070] For example, the eighth drive unit 129 also uses a motor, which, in conjunction with a gear and rack transmission structure, drives the translation base to move along the first direction.

[0071] When welding a single piece 10 of the skeleton using the welding device 100 in this embodiment, the horseshoe-shaped reinforcement 11 and the long stirrup are confined to the positioning slot 113. The first welding mechanism 120a moves along the first direction to a preset first welding position. The second welding mechanism 120b moves as a whole along the first direction, and the two second welding components move along the second direction to the second welding position and the third welding position, respectively. The third welding mechanism 120c moves along the first direction to a preset fourth welding position. The clamping components 131 in the first clamping mechanism 130 move along the second direction to the preset first clamping position and the second clamping position, and clamp the two clamping sections of the long stirrup. Then, the first welding component, the second welding component, and the third welding component descend, so that the upper electrode 122 abuts against the reinforcing bar, and the lower electrode 123 rises to clamp the reinforcing bar together with the upper electrode 122, and the welding operation begins. After welding is completed, each welding mechanism 120 and the first clamping mechanism 130 return to the initial position, completing the welding operation.

[0072] Continue to refer to Figure 2 As shown, in order to guide the movement of the welding device 100, the T-beam web skeleton single-piece production line in this embodiment also includes a moving track 500 extending along a first direction, and the pedestal is rolled on the moving track 500 by rollers.

[0073] The feeding device 200 includes two second clamping mechanisms spaced apart along a first direction. Both second clamping mechanisms can drive the reinforcing bars to move along the first direction, the second direction, and a third direction, with the third direction being vertical. When transferring the reinforcing bars, the two clamping mechanisms respectively clamp both ends of the reinforcing bar's length.

[0074] As for the unloading device 700, an existing robotic arm can be used, and will not be described in detail here.

[0075] Furthermore, the T-beam web skeleton single-piece production line also includes a straightening machine 900 and a conveyor line 800. Two straightening machines 900 are arranged at intervals along the second direction. The conveyor line 800 is located on the side away from the welding device 100 of the horseshoe-shaped bending device 300 and the long stirrup bending device 400. Two conveyor lines 800 are also arranged at intervals along the second direction. The two conveyor lines 800 are used to transport the steel bars straightened by the two straightening machines 900 to the two feeding devices 200 along the first direction.

[0076] It should be emphasized that, in the first direction, the distance between the straightening machine 900 and the horseshoe-shaped bending device 300 is less than the distance between the straightening machine 900 and the long stirrup bending device 400. Obviously, the length of the steel bar used to bend into horseshoe-shaped bars is less than the length of the steel bar used to bend into long stirrups. Therefore, the width of the support plate used to support the steel bar in the long stirrup bending device 400 in the second direction is greater than the width of the support plate used to support the steel bar in the horseshoe-shaped bending device 300. In order to further save space, the length of the conveyor line 800 used to convey the steel bar for horseshoe-shaped bars is less than the length of the conveyor line 800 used to convey the steel bar for long stirrups. Moreover, the conveyor line 800 used to convey the steel bar for horseshoe-shaped bars is closer to the welding device 100 in the second direction than the conveyor line 800 used to convey the steel bar for long stirrups.

[0077] For example, conveyor line 800 is a roller conveyor line.

[0078] The embodiments of this utility model also propose a method for producing a single piece of T-beam web skeleton, which mainly includes the following steps:

[0079] Step 1: After the steel bars are straightened by the straightening machine 900, they are transported by two conveyor lines 800 to the corresponding feeding stations of the feeding devices 200.

[0080] Step 2: One of the feeding devices 200 grabs the steel bar and conveys it along the second direction to the horseshoe-shaped bending device 300, which bends it into a horseshoe shape; at the same time, the other feeding device 200 grabs the steel bar and conveys it along the second direction to the long stirrup bending device 400, which bends it into a long stirrup.

[0081] Step 3: The welding device 100 moves along the first direction to the side of the tendon bending device 300 along the second direction, and the cantilever 600 corresponding to the tendon bending device 300 transfers the tendon from the tendon bending device 300 to the welding device 100.

[0082] Step 4: The welding device 100 moves along the first direction to one side of the long stirrup bending device 400 along the second direction, and the cantilever crane 600 of the long stirrup bending device 400 transfers the long stirrup from the long stirrup bending device 400 to the welding device 100.

[0083] Understandably, since the horseshoe tendon bending device 300 operates first compared to the long stirrup bending device 400, and both sides of the horseshoe tendon can be bent simultaneously, while the long stirrup is bent from one side, the horseshoe tendon is formed before the long stirrup. During the bending and forming of the long stirrup, the welding device 100 receives the horseshoe tendon transferred from the cantilever crane 600 and moves towards the long stirrup bending device 400. The process arrangement is compact and the production efficiency is high.
