[0058] refer to Figure 1-Figure 14 As shown, in this embodiment, a single-piece production line for a T-beam web skeleton is proposed, comprising a feeding device 200, a tendon bending device 300, a long stirrup bending device 400, a welding device 100, a cantilever crane 600 and a feeding device 700, wherein the tendon bending device 300 and the long stirrup bending device 400 are arranged along a first direction, the tendon bending device 300 is used for forming the tendon, and the long stirrup bending device 400 is used for forming the long stirrup, the feeding device 200 and the welding device 100 are respectively arranged on opposite sides of the tendon bending device 300 and the long stirrup bending device 400 along a second direction, and two feeding devices 200 are arranged along the first direction, one of which is used to deliver the steel bars to the tendon along the second direction A bending device 300, and another one is used to deliver the steel bars to the long stirrup bending device 400 along the second direction. The welding device 100 is used to weld the horseshoe tendons and the long stirrups. The cantilever crane 600 is arranged on the side of the welding device 100 away from the feeding device 200, and there are two cantilever cranes 600 also arranged along the first direction, one of which is used to deliver the horseshoe tendons 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. The unloading device 700 is arranged between the two cantilever cranes 600, and is used to take out the formed T-beam web skeleton single piece from the welding device 100. The first direction and the second direction are two directions perpendicular to each other on the horizontal plane.

[0059] The above-mentioned T-beam web frame single-piece production line can complete the automatic loading, bending, welding forming and unloading of the T-beam web frame single piece (hereinafter referred to as the frame single piece 10) in the production process. It has a high degree of automation, can realize continuous production, and has a concentrated working area, occupying a small space.

[0060] refer to Figure 2 As shown, the welding device 100 includes a pedestal 110, a welding mechanism 120 and a traveling mechanism. The pedestal 110 is arranged on the traveling mechanism, and the welding mechanism is arranged on the pedestal. The traveling mechanism is used to drive the pedestal 110 to move along a first direction. A plurality of positioning slot seats 113 are arranged on the pedestal 110. The positioning slot seats 113 are provided with a plurality of positioning slots with upward notches for positioning the horseshoe tendon 11 and the long stirrups. The welding mechanism 120 is arranged on the pedestal 110, and is used to weld and fix the horseshoe tendon 11 and the long stirrups.

[0061] refer to Fig.15 As shown, the horseshoe tendon 11 and the long stirrups constituting the skeleton single piece 10 include a first overlap point located at the first end of the long stirrups along the length direction, and a second overlap point and a third overlap point located at opposite sides of the long stirrups along the width direction and symmetrically arranged. In order to stably connect the horseshoe tendon 11 and the long stirrups, it is necessary to weld and fix at the first overlap point, the second overlap point, and the third overlap point, that is, the first overlap point is the first welding point A, the second overlap point is the second welding point B, and the third overlap point is the third welding point C. On this basis, the welding mechanism 120 includes a first welding mechanism 120a and a second welding mechanism 120b, wherein the first welding mechanism 120a includes a first welding assembly for welding and fixing the first welding point A, and the second welding mechanism 120b includes two groups of second welding assemblies symmetrically arranged along the second direction, respectively used to weld and fix the second welding point B and the third welding point C. In order to avoid the horseshoe tendon 11 and the long stirrup when they are placed in the positioning groove seat 113, the first welding assembly in the first welding mechanism 120a is slidably arranged on the platform 110 along the first direction, and the first welding mechanism 120a includes a first driving member 125 that drives the first welding assembly to move along the first direction. The two groups of second welding assemblies in the second welding mechanism 120b are slidably arranged on the platform 110 along the second direction, and the second welding mechanism 120b includes a second driving member 126 that drives the two groups of second welding assemblies to move toward or away from each other along the second direction. The first direction is the length direction of the long stirrup ( Figure 1 The second direction is the width direction of the long stirrup ( Figure 1 The first direction and the second direction are perpendicular to each other.

[0062] Continue to refer Fig.15 As shown, the long stirrups constituting the skeleton monolithic sheet 10 are formed by bending steel bars, and the long stirrups include a connecting section 12, an extension section 13 and a bending section 14, wherein the connecting section 12 is U-shaped, and the two extension sections 13 are respectively connected to the two ends of the connecting section 12, and the two bending sections 14 are formed by bending the two extension sections 13 toward each other. In order to maintain the stability of the shape of the long stirrups, the two bending sections 14 need to be connected and fixed, therefore, the skeleton monolithic sheet 10 also includes a fourth welding point D located at one end of the long stirrups away from the first welding point A. Based on this, the welding mechanism 120 also includes a third welding mechanism 120c, and the third welding mechanism 120c includes a third welding assembly slidably disposed on the pedestal 110 along the first direction, and the third welding mechanism 120c also includes a third driving member 127 for driving the third welding assembly 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.

[0063] Since the two bent sections 14 of the long stirrups are not fixed, affected by the elasticity of the long stirrups themselves, the initial distance between the two extended sections 13 of the long stirrups placed on the positioning slot seat 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 assemblies 131 arranged to slide at intervals along the second direction and a fourth driving member 132 for driving the two clamping assemblies 131 to move toward or away from each other along the second direction. The two clamping assemblies 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.

[0064] The above-mentioned welding device 100 uses the first clamping mechanism 130 to cooperate with the positioning groove seat 113 on the base 110 to position the horseshoe tendon 11 and the long stirrups, and at the same time uses the welding mechanism 120 movably arranged on the base 110 to weld the welding points of the horseshoe tendon 11 and the long stirrups, thereby realizing automatic welding of the skeleton single piece 10 with high molding accuracy and production efficiency.

[0065] refer to Figure 3 As shown, the positioning slot seats 113 are grouped in pairs to form a positioning slot seat group, and the pedestal 110 includes three groups of positioning slot seat groups, two of which are used to support and position the horseshoe tendon 11, and one group is used to support and position the long stirrup. Specifically, for the convenience of description, the two groups of positioning slot seat groups used to support and position the horseshoe tendon 11 are respectively defined as the first positioning slot seat group and the second positioning slot seat group, and the positioning slot seat group used to support and position the long stirrup is defined as the third positioning slot seat group. The positioning slots set 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, and the positioning slots set on the two positioning slot seats 113 in the second positioning slot seat group penetrate the positioning slot seats 113 along the second direction.

[0066] More specifically, in order to reduce the difficulty of the horseshoe tendon 11 and the long stirrups entering the positioning slot, the notch of the positioning slot is set to be a trumpet shape that gradually converges from top to bottom.

[0067] 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 an escape opening for the welding mechanism 120 and the first clamping mechanism 130 to pass through, the positioning groove seat 113 is embedded in the top surface of the panel 112, and the bottom of the positioning slot on the positioning groove seat 113 is flush with the top surface of the panel 112, when the horseshoe tendon 11 and the long stirrup are placed in the positioning groove seat 113, the pedestal 110 can cooperate with the positioning groove seat 113 to support the horseshoe tendon 11 and the long stirrup, thereby reducing the possibility of deformation of the horseshoe tendon 11 and the long stirrup due to gravity.

[0068] 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 the second direction, and a fifth driving member 1312. The two clamping plates 1311 are both arranged on the mounting base plate 1313, at least one clamping plate 1311 is connected to the fifth driving member 1312, and the fifth driving member 1312 is configured to drive the clamping plate 1311 to reciprocate along the second direction to clamp or loosen the long stirrups.

[0069] Exemplarily, the fifth driving member 1312 is a cylinder, and in order to use the same fourth driving member 132 to make the two clamping assemblies 131 move toward or away from each other, the first clamping mechanism 130 also includes a flexible transmission structure, and the fourth driving member 132 is a motor, which is connected to the two clamping assemblies 131 through the flexible transmission structure. Specifically, the flexible transmission structure includes a sprocket and a chain, and the chain is wound between two sprockets spaced apart along the second direction, one of which is connected to the fourth driving member 132, and the two clamping assemblies 131 are respectively arranged on the upper and lower layers of the chain through a clamping plate, so that they can move toward or away from each other 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, and the clamping assembly 131 is slidably arranged on the support frame 133 along the second direction. The support frame 133 is also provided with a positioning guide rail for guiding the moving direction of the clamping assembly 131, and the clamping assembly 131 is slidably connected to the support frame 133 via the positioning guide rail.

[0070] refer to Figure 8-Figure 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 disposed on the pedestal 110 via a sliding base plate 121. The upper electrode 122 and the lower electrode 123 are spaced apart from each other on the sliding base plate 121. 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 steel bars for welding.

[0071] Exemplarily, the first driving member 125 and the sixth driving member 124 are both cylinders, the third driving member 127 is a motor, a rack is provided on the pedestal 110, and a gear meshing with the rack is provided on the motor as the third driving member 127. When the motor rotates, the gear meshing with the rack drives the third welding assembly to move in the first direction. The second driving member 126 also uses a motor, and the motor cooperates with the flexible transmission structure to drive the two second welding assemblies. It should be emphasized that in order to realize the synchronous movement of the two second welding assemblies toward and away from each other along the second direction, the two second welding assemblies are respectively arranged on the upper and lower layers of the flexible member (such as a chain) in the flexible transmission structure.

[0072] In order to make the upper electrode 122 fit 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, and multiple seventh driving members 128 can drive the corresponding first welding assembly, second welding assembly and third welding assembly to rise and fall.

[0073] In order to adapt to the welding of single-piece frames of different lengths, the second welding mechanism 120b further includes an eighth driving member 129, which is configured to drive the second welding assembly to move along the first direction. Specifically, the second welding mechanism 120b further includes a translation chassis, which is slidably arranged on the pedestal 110 along the first direction, and a sliding base plate 121 of the second welding mechanism 120b is arranged on the translation chassis. Driven by the eighth driving member 129, the sliding base plate 121 moves along the first direction together with the translation chassis.

[0074] Exemplarily, the eighth driving member 129 also adopts a motor, which cooperates with the gear rack transmission structure to drive the translation chassis to move along the first direction.

[0075] When the welding device 100 in this embodiment is used to weld the skeleton single piece 10, the horseshoe tendon 11 and the long stirrup are restricted on the positioning groove seat 113, the first welding mechanism 120a moves along the first direction to the preset first welding position, the second welding mechanism 120b moves along the first direction as a whole, and the two second welding assemblies move along the second direction to the second welding position and the third welding position, the third welding mechanism 120c moves along the first direction to the preset fourth welding position, the clamping assembly 131 in the first clamping mechanism 130 moves along the second direction to the preset first clamping position and the second clamping position, and clamps the two clamping sections of the long stirrup, then the first welding assembly, the second welding assembly, and the third welding assembly descend, so that the upper electrode 122 abuts against the steel bar, the lower electrode 123 rises and clamps the steel bar together with the upper electrode 122, and the welding operation begins. After the welding is completed, each welding mechanism 120 and the first clamping mechanism 130 return to the initial position to complete the welding operation.

[0076] Continue to refer Figure 2 As shown, in order to provide guidance for the movement of the welding device 100, the T-beam web frame single-piece production line in this embodiment also includes a movable track 500 extending along the first direction, and the platform is set on the movable track 500 by rollers.

[0077] The feeding device 200 includes two second clamping mechanisms spaced apart along the first direction, and both second clamping mechanisms can drive the steel bar to move along the first direction, the second direction and the third direction, and the third direction is the vertical direction. When transferring the steel bar, the two clamping mechanisms clamp the two ends of the length of the steel bar respectively.

[0078] As for the unloading device 700, an existing robotic arm may be used, which will not be further described here.

[0079] 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 of the horseshoe tendon bending device 300 and the long stirrup bending device 400 away from the welding device 100, and two conveyor lines 800 are also arranged at intervals along the second direction. The two conveyor lines 800 are respectively used to transport the steel bars corrected by the two straightening machines 900 to the two loading devices 200 along the first direction.

[0080] It should be emphasized that, in the first direction, the distance between the straightening machine 900 and the horseshoe tendon bending device 300 is smaller than the distance between the straightening machine 900 and the long stirrup bending device 400. Obviously, the length of the steel bar used to be bent into the horseshoe tendon is smaller than the length of the steel bar used to be bent into the long stirrup. 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 tendon bending device 300. In order to further save space, the length of the conveyor line 800 for conveying the steel bar for horseshoe tendon forming is smaller than the length of the conveyor line 800 for conveying the steel bar for long stirrup forming, and the conveyor line 800 for conveying the steel bar for horseshoe tendon forming is closer to the welding device 100 in the second direction than the conveyor line 800 for conveying the steel bar for long stirrup forming.

[0081] Exemplarily, the conveyor line 800 is a roller conveyor line.

[0082] The embodiment of the present invention also provides a method for producing a single piece of a T-beam web frame, which mainly includes the following steps:

[0083] Step 1: After being straightened by the straightening machine 900 , the steel bars are transported to the loading stations of the corresponding loading devices 200 through two conveyor lines 800 .

[0084] Step 2: One of the feeding devices 200 grabs the steel bar and transports it to the horseshoe tendon bending device 300 along the second direction, and the horseshoe tendon bending device 300 bends it into horseshoe tendon; at the same time, another feeding device 200 grabs the steel bar and transports it to the long stirrup bending device 400 along the second direction, and the long stirrup bending device 400 bends it into long stirrup.

[0085] Step 3: The welding device 100 moves along the first direction to one side of the tendon bending device 300 along the second direction, and the cantilever crane 600 corresponding to the tendon bending device 300 transfers the tendon from the tendon bending device 300 to the welding device 100.

[0086] 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 a long stirrup bending device 400 transfers the long stirrup from the long stirrup bending device 400 to the welding device 100.

[0087] It can be understood that since the horseshoe tendon bending device 300 operates before the long stirrup bending device 400, and both sides of the horseshoe tendon can be bent at the same time, while the long stirrup is bent from one side, the horseshoe tendon is formed before the long stirrup. During the bending and forming process of the long stirrup, the welding device 100 receives the horseshoe tendon transferred from the cantilever crane 600 and moves toward the long stirrup bending device 400. The process arrangement is compact and the production efficiency is high.

[0088] Step 5: The welding device 100 moves to the set material taking station and simultaneously welds the long stirrups and horseshoe reinforcements to form a single piece of the T-beam web skeleton.

[0089] Step 6: The material taking mechanism takes out the welded T-beam web frame single piece from the welding device 100, forming a complete cycle.
