DETAILED DESCRIPTION

[0033] The utility model is described in detail below in conjunction with the accompanying drawings.

[0034] like Figure 1As shown, a stepless flexible welded mesh production line includes a longitudinal reinforcement supply system 1, a transverse reinforcement supply system 2, an automatic welding machine 3, a traction system 4, a four-way mesh bending system 5, and a mesh conveying system 6. The longitudinal reinforcement supply system 1, the automatic welding machine 3, the transverse reinforcement supply system 2, the traction system 4, and the four-way mesh bending system 5 are arranged in sequence along the moving direction of the longitudinal reinforcement. The tops of the transverse reinforcement supply system 2 and the mesh conveying system 6 are arranged in sequence above the traction system 4 along the moving direction of the longitudinal reinforcement. The top of the mesh conveying system 6 passes through the traction system 4 and the four-way mesh bending system 5 in sequence and extends outward along the moving direction of the longitudinal reinforcement. The four-way mesh bending system 5 includes a mesh bending machine 51 and a lifting mechanism 52. The number of the mesh bending machines 51 is four, and the four mesh bending machines 51 are respectively placed around the lifting mechanism 52. The four mesh bending machines 51 can bend the steel mesh in four directions respectively. The longitudinal reinforcement supply system 1 delivers the longitudinal reinforcement to the automatic welding machine 3, while the transverse reinforcement supply system 2 delivers the transverse reinforcement to the other side of the automatic welding machine 3. After welding, a steel mesh is formed, which is then moved out through the traction system 4 and then transported to the four-way bending mesh system 5 through the mesh conveying system 6. The four-way bending mesh system 5 can bend the steel mesh in four directions without changing direction.

[0035] The longitudinal reinforcement supply system 1 includes an automatic longitudinal reinforcement machine 11, a longitudinal reinforcement wire rack 12, a longitudinal reinforcement placement vehicle 13, and a longitudinal reinforcement traction vehicle 14. The automatic longitudinal reinforcement machine 11, the longitudinal reinforcement wire rack 12, the longitudinal reinforcement placement vehicle 13, and the longitudinal reinforcement traction vehicle 14 are connected in sequence. The automatic longitudinal reinforcement machine 11, the longitudinal reinforcement wire rack 12, and the longitudinal reinforcement placement vehicle 13 in the longitudinal reinforcement supply system 1 adopt the structure described in the background document.

[0036] like Figure 2 As shown, the longitudinal reinforcement tractor 14 slides on the longitudinal reinforcement slide frame 141, and the longitudinal reinforcement tractor 14 includes a grabbing mechanism 142, a lifting mechanism 143 and a walking mechanism 144. The lifting mechanism 143 and the walking mechanism 144 in the longitudinal reinforcement tractor 14 adopt the structure described in the background document.

[0037] The grabbing mechanism 142 includes a lifting beam 142a, a guide rail connecting plate 142b is connected below the lifting beam 142a, a transmission assembly 142c and a clamping assembly 142d are arranged below the guide rail connecting plate 142, and the number of the clamping assemblies 142d is multiple, and the multiple clamping assemblies 142d are arranged in an array along the length direction of the lifting beam 142a;

[0038] like Figures 3 - 4As shown in the figure, the transmission assembly 142c includes a servo motor 142c1, a speed reducer 142c2, a synchronous pulley 142c3, a synchronous belt 142c4, a cylinder 142c5, and a guide sleeve 142c6. The speed reducer 142c2 is connected to the side end of the guide rail connecting plate 142b. The output end of the servo motor 142c1 is connected to the speed reducer 142c2. The number of synchronous pulleys 142c3 is two. One of them is connected to the output end of the speed reducer 142c, and the other is arranged at the other end in the length direction of the guide rail connecting plate 142b. The two synchronous pulleys 142c3 are synchronously rotated through the synchronous belt 142c4. The cylinder 142c5 is arranged on the synchronous belt 142c4 and synchronously moves along its length direction with the synchronous belt 142c4. The output end of the cylinder 142c5 is inserted into the guide sleeve 142c6, so that the guide sleeve 142c6 slides along the length direction of the guide rail connecting plate 142b. The other end of the guide sleeve 142c6 is connected to the jaw assembly 142d. When the servo motor 142c1 is started, the synchronous pulley 142c3 at the output end of the speed reducer 142c2 rotates, the synchronous belt 142c4 moves along the length direction of the guide rail connecting plate 142b and drives the cylinder 142c5 to move synchronously. The number of guide sleeves 142c6 is multiple and corresponds to the number of jaw assemblies 142d. The piston rod at the output end of the cylinder 142c5 enters the guide sleeve 142c6, and the intervals of the multiple guide sleeves 142c6 on the guide rail connecting plate 142b are adjusted to adapt to the arrangement of longitudinal bars with different densities.

[0039] As Figure 5 shown in the figure, the jaw assembly 142d includes a jaw cylinder 142d1, a clamping pin 142d2, a clamping spacer 142d3, and a clamping block group. The clamping pin 142d3 is arranged at the output end of the jaw cylinder 142d1. The number of clamping block groups is two. The two clamping block groups are relatively arranged below the jaw cylinder 142d1. The clamping block group includes two clamping blocks 142d4. The tops of the two clamping blocks 142d4 are cross - arranged. The distance between the bottoms of the two clamping blocks gradually increases and the bottoms are provided with anti - slip sawteeth. The two ends of the clamping pin 142d2 are respectively connected to the two clamping block groups and connected to the cross - position of the two clamping blocks 142d4. The number of clamping spacers 142d3 is two. The two clamping spacers 142d3 are respectively connected to the two relatively arranged clamping blocks 142d4. When the piston rod at the output end of the jaw cylinder 142d1 moves downward, it drives the clamping pin 142d2 to move downward. At this time, the opening at the bottom of the clamping block group becomes larger. When the piston rod moves upward, the opening at the bottom of the clamping block group becomes smaller. Without replacing the fixture, the clamping of longitudinal bars with different diameters can be realized.

[0040] The transverse bar supply system 2 includes an automatic bar batching machine 21, a wire gathering rack 22, a transverse bar receiving machine 23, and a transverse bar blanking rack 24. The automatic bar batching machine 21, the wire gathering rack 22, the transverse bar receiving machine 23, and the transverse bar blanking rack 24 are connected in sequence. The automatic bar batching machine 21 is arranged at the side end of the traction system 4, and the wire gathering rack 22, the transverse bar receiving machine 23, and the transverse bar blanking rack 24 are all arranged above the traction system 4 at one end close to the automatic welding machine 3. The bottom of the transverse bar receiving machine 23 is close to the automatic welding machine 3. After the transverse bars pass through the automatic bar batching machine 21, the wire gathering rack 22, the transverse bar receiving machine 23, and the transverse bar blanking rack 24 in sequence, they enter the automatic welding machine 3 in the opposite direction of the longitudinal bar transportation direction.

[0041] The automatic bar batching machine 21, the wire gathering rack 22, and the transverse bar receiving machine 23 of the transverse bar supply system 2 adopt the structures described in the background document.

[0042] As Figure 6 shown, the transverse bar receiving machine 23 includes a frame 231. The transverse bar receiving machine 23 is fixed above the traction system 4 through the frame 231. The frame 231 is arranged at one end of the traction system 4 in the width direction close to the automatic welding machine 3.

[0043] The transverse bar blanking rack 24 is arranged at one end of the frame 231 close to the automatic welding machine 3. The number of the transverse bar blanking racks 24 is multiple, and the multiple transverse bar blanking racks 24 are arranged in an array along the length direction of the frame 231.

[0044] As Figure 7As shown in the figure, the horizontal bar blanking rack 24 includes a chain support 241 and a connecting gusset plate 242. One end of the chain support 241 is fixed on the frame 231, and the bottom of the other end is connected to the connecting gusset plate 242. A steel bar guide plate 243 is provided at the bottom of the connecting gusset plate 242. One end of the steel bar guide plate 243 close to the automatic welding machine 3 is provided with a supporting table arranged horizontally, so that after the horizontal bar enters the steel bar guide plate 243, it falls onto the supporting table. Along the length direction of the chain support 241, a driving sprocket 244, a tensioning sprocket 245, and a driven sprocket 246 are arranged in sequence. The driving sprocket 244, the tensioning sprocket 245, and the driven sprocket 246 are axially connected to the chain support 241. The axis center of the driving sprocket 244 and the axis center of the tensioning sprocket 245 are at the same height, and the axis center of the driven sprocket 246 is lower than the axis center of the driving sprocket 244. A chain 247 passes through the driving sprocket 244 and the driven sprocket 246 and is tensioned by the middle tensioning sprocket 245. A plurality of spaced steel bar fixing chain plates 248 are arranged on the chain 247. The steel bar fixing chain plates 248 are provided with arc-shaped notches for supporting the horizontal bars. By externally connecting a servo motor and a speed reducer, the driving sprocket 244 rotates clockwise, driving the chain 247 to rotate clockwise along the driving sprocket 244, the tensioning sprocket 245, and the driven sprocket 246. The horizontal bars enter the horizontal bar blanking rack 24 from the horizontal bar receiving machine 23 and are clamped into the steel bar fixing chain plates 248, and then move along with the chain 247 to the supporting table at the bottom of the steel bar guide plate 243 at the bottom of the connecting gusset plate 242, and the horizontal bars are smoothly delivered to the automatic welding machine 3.

[0045] The automatic welding machine 3 and the traction system 4 both adopt the structures in the background document, which will not be elaborated here.

[0046] As Figure 8 As shown in the figure, the mesh conveying system 6 includes a gantry truss 61, an overhead crane 62, and a manipulator 63. The manipulator 63 is fixed above the gantry truss 61 through the overhead crane 62. The length direction of the gantry truss 61 is the same as the moving direction of the longitudinal bars. The overhead crane 62 is fixed on the gantry truss 61 and moves along the length direction of the gantry truss 61. The length direction of the overhead crane 62 is the same as the width direction of the gantry truss 61. The manipulator 63 is fixed on the gantry truss 61 and moves along the length direction and the vertical direction of the gantry truss 61.

[0047] The number of the manipulators 63 is two. The two manipulators 63 are arranged on the overhead crane 62 along the length direction of the overhead crane 62, so that the two manipulators 63 are respectively arranged at both ends of the transverse rib in the length direction, and are respectively grabbed to maintain the stability during grabbing. The manipulator 63 includes a lifting arm 631, a sliding box 632 and a clamping jaw 633. The lifting arm 631 is fixed on the overhead crane 62 through the sliding box 632. The lifting arm 631 slides along the length direction and the vertical direction of the overhead crane 62 through a driving component. The clamping jaw 633 is fixed at the lower end of the lifting arm 631. The clamping jaw 633 includes a support cross beam 633a whose length is arranged along the moving direction of the longitudinal rib and a plurality of cylinder manipulators 633b arranged at intervals at the lower end of the support cross beam. The steel bar mesh can be grabbed at multiple points along the length direction of the longitudinal rib through the plurality of cylinder manipulators 633b to maintain the stability during movement.

[0048] As Figure 9 shown, the driving component includes a first driving component 634 and a second driving component 635.

[0049] The first driving component 634 includes a first servo motor 634a, a first reduction gear, a first reduction gear gear and a first rack 634b. The output end of the first servo motor 634a is connected to the first reduction gear. The first reduction gear is fixed inside the sliding box 632. The first reduction gear gear is connected to the output end of the first reduction gear. A first rack 634b meshing with the first reduction gear gear is arranged inside the overhead crane 23. The length direction of the first rack 634b is the same as the length direction of the overhead crane 23. When the first servo motor 634a is started, the first reduction gear starts with the first servo motor 634a. The first reduction gear gear at the output end of the first reduction gear rotates axially. When the first reduction gear gear rotates, it meshes with the first rack 634b below it and moves along the length direction of the overhead crane 62 through the first rack 634b, thereby driving the sliding box 632 connected to the first driving component 634 to move synchronously, and the lifting arm 631 connected to the sliding box 632 moves synchronously.

[0050] The second driving assembly includes a second servo motor 635a, a second speed reducer, a second speed reducer gear, and a second rack 635b. The output end of the second servo motor 635a is connected to the second speed reducer. The second speed reducer is fixed outside the sliding box 632. The second speed reducer gear is connected to the output end of the second speed reducer. A second rack 635b meshing with the second speed reducer gear is arranged on the lifting arm 631. The length direction of the second rack 635b is the same as the length direction of the lifting arm 631. When the second servo motor 635a is started, the second speed reducer starts with the second servo motor 635a. The second speed reducer gear at the output end of the second speed reducer rotates axially. When the second speed reducer gear rotates, it moves along the length direction of the second rack 635b at its side end, thereby driving the sliding box 632 connected to the second driving assembly 635 to move synchronously in the vertical direction, and the lifting arm 631 connected to the sliding box 632 moves synchronously.

[0051] As Figures 10 - 12 shown, the bending machine 51 includes a bending machine frame 511. Above the bending machine frame 511, there are arranged a lifting cross beam 512, a bending mandrel 513, and a bending arm 514. The lifting cross beam 512 is fixed in the middle of the bending machine frame 511 and slides up and down along the bending machine frame 511. The length direction of the lifting cross beam 512 is the same as the length direction of the bending machine frame 511. The bending mandrel 513 is arranged above the lifting cross beam 512 and slides along the length direction of the lifting cross beam 512. Above the bending mandrel 513, there is arranged a bending sleeve 513a. The bending sleeve 513a is cylindrical and is axially connected to the upper side end of the bending mandrel 513. The steel bar rotates axially along the bending sleeve 513a and is bent. The bending arm 514 is axially connected to the upper part of the lifting cross beam 512. At the bottom of the bending machine frame 511, there is arranged a first oil cylinder 515. The first oil cylinder 515 is axially connected to the bending machine frame 511. The output end of the first oil cylinder 515 is axially connected to the bending arm 514. In the initial position, the top of the bending arm 514 is horizontal with the lifting cross beam 512. When in use, the output end of the first oil cylinder 515 jacks up, causing the bending arm 514 connected thereto to jack up and rotate axially along the bending machine frame 511.

[0052] A second oil cylinder 516 is arranged on the lifting cross beam 512. A moving mandrel seat 517 is arranged at the bottom of the bending mandrel 513. The output end of the second oil cylinder 516 is inserted into the moving mandrel seat 517 and drives the moving mandrel seat 517 to slide along the length direction of the lifting cross beam 512. By adjusting the distance between the bending mandrels 513, different-density steel bar meshes can be adapted.

[0053] The bending arm 514 includes a driving arm round tube 514a and a bending shaft 514b. The length directions of the driving arm round tube 514a and the bending shaft 514b are the same as the length direction of the bending screen frame 511. The bending shaft 514b is arranged on the driving arm round tube 514a along the length direction of the driving arm round tube 514a and is fixed to the driving arm round tube 514a through a bending shaft seat 514c. The driving arm round tube 514a is axially connected to the upper part of the bending screen frame 511, and one end of the driving arm round tube 514a away from the bending shaft 514b is axially connected to the output end of the first oil cylinder 515.

[0054] Place one end of the steel bar mesh on the lifting cross beam 512, then insert the end of the steel bar mesh under the bending sleeve 513a at the side end of the bending die 513 and extend it above the bending shaft 514b. Start the first oil cylinder 515 to make the output end of the oil cylinder lift upward, and make the driving arm round tube 514a rotate axially along the lifting cross beam 512 and then lift upward. At this time, the end of the steel bar mesh moves upward along with the bending shaft 514b and bypasses along the outer circumference of the bending sleeve 513a to form a bend.

[0055] As Figure 13 shown, the lifting mechanism 52 includes a support frame 521, a lifting square tube 522, and a lifting platform 523. The number of the support frames 521 is multiple groups. The support frames 521 are arranged perpendicular to the moving direction of the steel bar mesh. The number of the lifting square tubes 522 is multiple. The multiple lifting square tubes 522 are distributed in an array above the support frame. The length direction of the lifting square tube 522 is perpendicular to the length direction of the support frame 521. The lifting platform 523 is arranged above the lifting square tube 522.

[0056] During use, the longitudinal bars are transported to the automatic welding machine 3 through the longitudinal bar supply system 1, and the transverse bars are transported to the automatic welding machine 3 through the transverse bar supply system 2. The two supply systems transport the steel bars synchronously to ensure the welding speed. The welded steel bar mesh is transported from the automatic welding machine 3 to the front end of the four-way bending screen system 5 through the traction system 4. The steel bar mesh is grabbed and moved by the mesh conveying system 6 and then placed on the lifting mechanism 52 of the four-way bending screen system 5. Finally, the four bending screen machines 51 arranged in four directions complete the bending of the steel bar mesh in four directions.
