Description

Technical Field

[0001] The present application relates to the technical field of steel bar skeleton forming, and in particular to a manufacturing device and a manufacturing method for a modular welded steel bar skeleton. Background Art

[0002] Beams, columns and shear walls are important load-bearing components in buildings. The internal steel skeleton is an important component to ensure the normal use of the components. The steel skeleton consists of longitudinal bars and stirrups. In traditional construction, the steel skeleton is usually made by workers tying the longitudinal bars and stirrups together on site. However, The steel frame tied on site has problems such as low precision and multiple steps, which affects construction efficiency.

[0003] With the development of building industrialization, modular technology, due to its high efficiency and environmentally friendly features, has become a key direction for the transformation and upgrading of the construction industry. During construction, multiple steel skeletons are assembled into different modules according to the needs of the load-bearing components. For example, shear walls can be assembled into L-shaped or T-shaped modules. Using these assembled modules for construction can reduce the number of construction steps and shorten the construction period.

[0004] The steel skeletons to be assembled are usually made directly in the factory. Although the related art provides automatic forming equipment for the steel skeletons to improve construction efficiency, when the steel skeletons need to be connected during on-site construction, mechanical connection and overlapping methods are generally adopted. When the steel bars are overlapped, the overlapping steel bars need to be offset. However, the steel skeletons in the related art still need to be adjusted twice when connected on the construction site to offset the overlapping steel bars and thus overlap. However, the process of secondary adjustment of the steel skeleton affects construction efficiency. Summary of the Invention

[0015] By adopting the above technical solution, after the stirrups are placed in the stirrup placement seat, the stirrup clamping assembly clamps the stirrups, reducing the possibility of the stirrups moving on the stirrup placement seat. After the longitudinal bars pass through the stirrups, the reinforcement removal assembly removes the stirrups from the stirrup placement seat and sequentially moves them to the designated welding position to weld them to the longitudinal bars, thereby completing the production of the steel skeleton.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1 -Attached Figure 9 This application is described in further detail.

[0029] Example 1 Example 1 of the present application discloses a modular welded steel frame manufacturing device. Figure 1 As shown, the manufacturing equipment of modular welded steel bar skeleton includes a base frame 1, a longitudinal reinforcement conveying device 2, a bending device 3 and a welding processing device. Among them, the welding processing device includes a stirrup conveying device 4, a welding device 5 and a discharging device 6.

[0030] like Figure 1 and Figure 2 As shown, the longitudinal reinforcement conveying device 2 includes a longitudinal reinforcement driving assembly 21 and a support base moving assembly 22. The longitudinal reinforcement driving assembly 21 includes a driving support base 211 and a longitudinal reinforcement driving member 212; the support base moving assembly 22 includes a conveying support frame 221, a conveying translation mechanism 222, and a conveying lifting mechanism 223.

[0031] Specifically, the conveying support frame 221 is fixedly connected to the base frame 1, the conveying translation mechanism 222 includes a translation drive 2221 and a translation seat 2222, and the conveying lifting mechanism 223 includes a screw 2231, a lifting drive 2232, and a guide rod 2233. In this embodiment 1, the body of the translation drive 2221 is fixedly connected to the conveying support frame 221, the output end of the translation drive 2221 is fixedly connected to the translation seat 2222, the ends of the screw 2231 and the guide rod 2233 are respectively fixedly connected to a translation seat 2222, and both translation seats 2222 are slidably connected to the base frame 1. Preferably, the pneumatic push rod of the translation drive 2221 can cause the screw 2231 and the guide rod 2233 to move horizontally on the conveying support frame 221 through the translation drive 2221. The lifting drive member 2232 is mounted on the screw rod 2231. The driving support base 211 is fixedly connected to the body of the lifting drive member 2232. The guide rod 2233 is provided on the driving support base 211. Preferably, the lifting drive member 2232 is a through-type motor, which can drive the support base 211 to move in the vertical direction. The longitudinal rib driving member 212 is mounted on the driving support base 211. Preferably, the longitudinal rib driving member 212 is a wheel set with a motor installed on the wheel set to rotate the wheel set. When the longitudinal rib is placed on the longitudinal rib driving member 212, the wheel set can drive the longitudinal rib to move.

[0032] like Figure 2As shown, in this embodiment 1, two conveying translation mechanisms 222 are mounted on the conveying support frame 221, each conveying translation mechanism 222 is correspondingly mounted on a conveying lifting mechanism 223, and each conveying lifting mechanism 223 is mounted on three longitudinal reinforcement driving members 212. Through the cooperation of the conveying translation mechanism 222 and the conveying lifting mechanism 223, the distance between each longitudinal reinforcement driving member 212 can be adjusted separately, thereby adjusting the spacing between the longitudinal reinforcements. This makes it possible to weld reinforcement skeletons of different sizes, thereby improving the versatility of the equipment.

[0033] like Figure 1 and Figure 3 As shown, the bending device 3 includes a bending movement assembly 31, a bending mechanism 32, and a bending support frame 33. The bending movement assembly 31 includes a bending translation mechanism 311 and a bending lifting mechanism 312. The bending mechanism 32 includes a bending support seat 321, a bending connection seat 322, a bending clamping assembly, and a bending rotating member 326. The bending clamping assembly includes a bending limit block 323, a first bending member 324, and a second bending member 325.

[0034] Specifically, such as Figure 3 and Figure 4 As shown, the bending support frame 33 is fixedly connected to the base frame 1, and two bending and translation mechanisms 311 are installed in the bending support frame 33, and a bending and lifting mechanism 312 is installed on each bending and translation mechanism 311. In this embodiment 1, the structure of the bending and translation mechanism 311 is the same as that of the conveying and translation mechanism 222, and the structure of the bending and lifting mechanism 312 is the same as that of the conveying and lifting mechanism 223. A total of three bending support seats 321 are installed on each conveying and lifting mechanism 223, wherein the connection method between the bending support seat 321 and the bending and lifting mechanism 312 is the same as the connection method between the driving support seat 211 and the conveying and lifting mechanism 223. Under the drive of the bending and translation mechanism 311 and the bending and lifting mechanism 312, the spacing between adjacent bending support seats 321 can be adjusted so as to adapt to the position of the longitudinal rib driving member 212.

[0035] like Figure 4 and Figure 5As shown, a bending mechanism 32 is mounted on each bending connection seat 322. The bending connection seat 322 is rotatably connected to the bending support seat 321. The body of the bending rotating member 326 is fixedly connected to the bending support seat 321. The output end of the bending rotating member 326 is transmission-connected to the bending connection seat 322. Preferably, the bending rotating member 326 is a motor. In this embodiment 1, the output end of the bending rotating member 326 is connected to the bending connection seat 322 via a transmission belt. In other embodiments, the output end of the bending rotating member 326 and the bending connection seat 322 may also be chain-driven. The limit block 323 is fixedly connected to the bending connection seat 322. The first bending member 324 includes a pneumatic push rod and a push wheel. The body of the pneumatic push rod is fixedly connected to the bending connection seat 322. The output end of the pneumatic push rod is fixedly connected to the push wheel. The pneumatic push rod can drive the push wheel to move, so that when the longitudinal reinforcement passes, the first bending member 324 can push the longitudinal reinforcement through the push wheel. At the same time, the wheel surface of the push wheel is sunken, so that when the wheel surface of the push wheel abuts against the longitudinal reinforcement, the moving direction of the longitudinal reinforcement can be limited, thereby improving the stability of the longitudinal reinforcement movement. The structure of the second bending member 325 is the same as that of the first bending member 324. A mounting hole 3221 is provided at one end of the bending connection seat 322. After the longitudinal reinforcement passes through the mounting hole 3221, it passes through the limit block 323, the first bending member 324 and the second bending member 325 in sequence. At the same time, the limit block 323, the first bending member 324 and the second bending member 325 are respectively located on both sides of the longitudinal reinforcement.

[0036] When placing the longitudinal reinforcement, first adjust the position of each longitudinal reinforcement driving member 212 and the corresponding bending mechanism 32 so that each longitudinal reinforcement can be placed straight on the longitudinal reinforcement driving member 212 and the bending mechanism 32. Specifically, when placing the longitudinal reinforcement, one end of the longitudinal reinforcement needs to be passed through the mounting hole 3221 so that the longitudinal reinforcement is placed on the longitudinal reinforcement driving member 212 and the limiting block 323.

[0037] It should be noted that after the steel skeleton is formed and transported to the construction site for assembly, since two adjacent steel skeletons need to be overlapped, the overlapping sections of the overlapping steel bars need to be staggered to facilitate the overlap. Therefore, it is necessary to bend one end of the longitudinal bar to divide the longitudinal bar into a bent overlapping section and a straight main section. The overlapping section is used to overlap with other steel skeletons, and the main section is used to be welded with stirrups to form the steel skeleton. At the same time, in order to meet the overlap requirements, the overlapping section of the longitudinal bar needs to be bent twice so that the part of the overlapping section of the longitudinal bar away from the main section is parallel to the main section.

[0038] In Example 1 of the present application, after the longitudinal bar is placed in the stop block 323, the longitudinal bar is moved so that the first bending point is at the position of the stop block 323. During the first bending, the push wheel of the first bending member 324 pushes the bar toward the stop block 323. Since the stop block 323 restricts the movement of the longitudinal bar at this time, the longitudinal bar bends at a specified angle. After the longitudinal bar is bent for the first time, the longitudinal bar driving member 212 drives the longitudinal bar to move. At the same time, the push wheel of the first bending member 324 moves to a specified position, cooperating with the stop block 323 to restrict the movement direction of the main section of the longitudinal bar, thereby reducing the possibility of the longitudinal bar shifting during movement.

[0039] After the longitudinal bar moves a specified distance, the second bending point is positioned at the first bending member 324. At this point, the portion of the longitudinal bar that has been bent the first time passes through the second bending member 325. Furthermore, when the second bending point is positioned at the first bending member 324, the push wheel of the first bending member 324 moves a specified distance and cooperates with the limit block 323 to clamp the longitudinal bar, stopping the longitudinal bar from moving. After the longitudinal bar stops moving, the push wheel of the second bending member 325 moves a specified distance, pushing the longitudinal bar toward the first bending member 324. Under the restraint of the push wheel of the first bending member 324, the longitudinal bar bends a second time, causing the bent section of the longitudinal bar away from the main section to be parallel to the main section, thereby meeting the overlap requirements.

[0040] In addition, since the bending directions of the longitudinal bars at different positions of the steel skeleton are different, the bending directions of the longitudinal bars of different steel skeletons are also different. Therefore, it is necessary to adjust the direction of the bending section of the longitudinal bar to meet the production requirements of different steel skeletons. In this embodiment 1, after the second bending member 325 completes the second bending, the push wheels of the first bending member 324 and the push wheels of the second bending member 325 are respectively located on both sides of the longitudinal bar and press against the longitudinal bar, so that the longitudinal bar is clamped under the cooperation of the push wheels of the first bending member 324 and the second bending member 325. After the longitudinal bar is clamped, the bending rotating member 326 drives the bending connecting seat 322 to rotate a specified angle, so that the longitudinal bar rotates around the central axis, thereby adjusting the direction of the bending section of the longitudinal bar. At the same time, the push wheel of the first bending member 324 presses against the main section of the longitudinal bar, and the push wheel of the second bending member 325 presses against the bending section of the longitudinal bar, which increases the torque driving the rotation of the longitudinal bar, thereby improving the reliability of the longitudinal bar rotating with the rotating plate at a specified angle.

[0041] like Figure 1 、 Figure 6 and Figure 7As shown, the stirrup conveying device 4 includes a stirrup placement frame 41, a stirrup placement seat 42, a stirrup clamping assembly 43, and a stirrup removal assembly 44. The stirrup clamping assembly 43 includes a clamping translation mechanism 431, a clamping lifting mechanism 432, a clamping support seat 433, and a clamping rod 434. The stirrup placement frame 41 is fixedly connected to the base frame 1, and the stirrup placement seat 42 is fixedly connected to the stirrup placement frame 41. The stirrup placement seat 42 is provided with a plurality of placement slots 421, which separate adjacent stirrups through the placement slots 421, thereby providing clamping space for the stirrup removal member 443, making it easier for the stirrup removal member 443 to clamp. The clamping support seat 433 is slidably connected to the stirrup placement frame 41, the body of the clamping translation mechanism 431 is fixedly connected to the stirrup placement frame 41, and the output end of the clamping translation mechanism 431 is connected to the clamping support seat 433. In this embodiment 1, the clamping translation mechanism 431 is a linear module, and the clamping translation mechanism 431 can make the clamping support seat 433 move horizontally on the stirrup placement frame 41. A clamping lifting mechanism 432 is installed on the clamping support seat 433, and the structure of the clamping lifting mechanism 432 is the same as that of the conveying lifting mechanism 223. A through hole 4331 is installed on the clamping support seat 433, and one end of the clamping rod 434 passes through the through hole 4331 and is connected to the clamping lifting mechanism 432. The clamping rod 434 can be moved vertically on the clamping support seat 433 through the clamping lifting mechanism 432. In this embodiment 1, two clamping support seats 433 are installed in total, and three clamping rods 434 are installed on each stable support seat. Through the cooperation of the clamping lifting mechanism 432 and the clamping translation mechanism 431, the clamping rod 434 can move in the vertical and horizontal directions, so that it can adapt to the position of the longitudinal reinforcement. At the same time, after the stirrups are placed on the stirrup placement seat 42, the clamping translation mechanism 431 drives the two clamping support seats 433 away from each other, so that the clamping rods 434 on the two clamping support seats 433 respectively abut against the stirrups, thereby clamping the stirrups, reducing the possibility of the stirrups moving on the stirrup placement seat 42, and thereby improving the reliability of the stirrup removal piece 443 in removing the stirrups from the stirrup placement seat 42.

[0042] like Figure 1 and Figure 8As shown, the reinforcement removal assembly 44 includes a reinforcement removal support frame 441, a reinforcement removal drive 442 and a reinforcement removal member 443. The welding device 5 includes a welding support frame 51, a welding drive 52 and a welding gun 53. The reinforcement removal support frame 441 is fixedly connected to the stirrup placement frame 41 and the welding support frame 51, and one end extends a distance away from the welding support frame 51. The body of the reinforcement removal drive 442 is connected to the reinforcement removal support frame 441, and the output end of the reinforcement removal drive 442 is fixedly connected to the reinforcement removal member 443. Preferably, the reinforcement removal drive 442 is a three-axis linear module, and the reinforcement removal member 443 is an electric clamp. The reinforcement removal drive 442 can drive the reinforcement removal member 443 to move in the three directions of x-axis, y-axis and z-axis on the reinforcement removal support frame 441, so that the reinforcement removal member 443 moves to the position of the stirrup placement seat 42 to remove the stirrup.

[0043] like Figure 1 and Figure 8 As shown, the welding support frame 51 is fixedly connected to the base frame 1. The body of the welding driver 52 is connected to the welding support frame 51. The output end of the welding driver 52 is connected to the welding gun 53. Preferably, the welding driver 52 is a two-axis linear module that can drive the welding gun 53 to move in two directions in the vertical plane. After the stirrups are moved to the designated position, the welding driver 52 moves the welding gun 53 to the intersection of the stirrups and the longitudinal reinforcement to perform welding. In this embodiment 1, welding guns 53 are installed on all four sides of the stirrups, respectively, to weld one side of the stirrups.

[0044] After the longitudinal bar is bent and the orientation of the bent section is adjusted, the longitudinal bar driver 212 drives the longitudinal bar through the through-hole 4331 and then through the inner side of the stirrup to move to the designated position. As the longitudinal bar moves to the designated position, the push wheels of the first bending member 324 and the second bending member 325 press against the longitudinal bar, further improving the accuracy of the longitudinal bar's movement to the designated position. Furthermore, the clamping rod 434 supports the longitudinal bar, improving its stability during movement.

[0045] like Figure 1 and Figure 8 As shown, the discharge device 6 includes a discharge support frame 61, a discharge drive member 62, a discharge member 63 and a discharge platform 64. The discharge support frame 61 is slidably connected to the base frame 1, the body of the discharge drive member 62 is connected to the discharge support frame 61, and the output end of the discharge drive member 62 is fixedly connected to the discharge member 63. Preferably, the discharge drive member 62 is a two-axis linear module, and the discharge member 63 is an electric clamp. The discharge drive member 62 can drive the discharge member 63 to move in two directions in the vertical plane.

[0046] After the reinforcement removal member 443 moves the first stirrup to the designated position and welds it to the longitudinal reinforcement, the reinforcement removal member 443 continues to move the welded stirrup to the position of the discharge support frame 61. The discharge drive member 62 drives the discharge member 63 to move, causing the discharge member 63 to clamp the first welded stirrup. At this point, the reinforcement removal member 443 releases the first stirrup and moves to the position of the stirrup placement seat 42 to clamp the second stirrup before moving to the position of the welding device 5. Simultaneously, the discharge support frame 61 moves a designated distance, moving the second longitudinal reinforcement to the position where the stirrup is to be welded to the welding device 5. As the discharge support frame 61 gradually moves the longitudinal reinforcement, the reinforcement removal member 443 sequentially moves the stirrups to the position of the welding device 5, allowing the longitudinal reinforcement to be gradually welded to the stirrups. In addition, the discharge platform 64 is located below the longitudinal reinforcement and is fixedly connected to the base frame 1. The welded portion of the longitudinal reinforcement is placed on the discharge platform 64 and moves along the discharge platform 64 as the discharge support frame 61 moves, improving the stability of the longitudinal reinforcement movement process.

[0047] In addition, if Figure 9 As shown, the stirrups in Example 1 of the present application are in the form of grid stirrups, which are welded from multiple steel bars. Compared with the traditional steel skeleton, in which the stirrups need to be bent and formed on site, the grid stirrups are more convenient for automated production in the factory, thereby improving the production efficiency of the steel skeleton. In addition, the multiple steel skeletons produced by this application can be spliced ​​into "type I" modules, "T-type" modules or "L-type" modules. After the different modules are transported to the construction site, they can be further spliced ​​according to construction needs, thereby forming an overall steel skeleton of different load-bearing components (such as shear walls) in the building. Compared with the traditional on-site binding construction method, the construction efficiency is improved and the construction period is reduced.

[0048] The implementation principle of the manufacturing equipment of a modular welded steel bar skeleton in Example 1 of the present application is as follows: Adjust the positions of the longitudinal reinforcement driving member 212 and the bending mechanism 32 according to the spacing between the longitudinal reinforcements on the steel frame, so that the longitudinal reinforcements are placed flat on the longitudinal reinforcement driving member 212 and the limit block 323, and the first bending point of the longitudinal reinforcement is at the limit block 323.

[0049] The first bending member 324 pushes the longitudinal bar toward the stopper 323, where it undergoes a first bend. The bar then moves to a designated position, with a second bend located at the location of the first bending member 324. Driven by the second bending member 325, the longitudinal bar moves toward the first bending member 324, where it undergoes a second bend, ensuring that the longitudinal bar meets the overlap requirements.

[0050] Driven by the longitudinal reinforcement driving member 212 , the first welding point of the longitudinal reinforcement moves to the welding device 5 . At the same time, the reinforcement removing member 443 moves the first stirrup to the welding device 5 , and under the operation of the welding gun 53 , the stirrup is welded to the longitudinal reinforcement.

[0051] The bar removal member 443 continues to move the first welded stirrup to the discharge device 6. After the discharge member 63 clamps the first welded stirrup, the bar removal member 443 returns to the stirrup placement seat 42 to clamp the next stirrup. At the same time, the discharge member 63 drives the welded stirrup to move a specified distance, so that the next welding point of the longitudinal reinforcement is located at the welding device 5. As the discharge member 63 drives the longitudinal reinforcement to move step by step, the bar removal member 443 sequentially moves the stirrups and the longitudinal reinforcement to weld them, and finally the steel skeleton is formed.

[0052] Example 2 Example 2 of the present application discloses a method for manufacturing a modular welded steel bar skeleton, comprising the following steps: S1, placing the longitudinal reinforcement on the longitudinal reinforcement conveying device 2 and the bending and clamping assembly, and placing the stirrups on the welding processing device; S2. Move the longitudinal reinforcement to the designated position, and bend and clamp the longitudinal reinforcement twice with the bending and clamping assembly; S3, the bending rotating member 326 drives the bending connecting seat 322 to rotate, so that the longitudinal reinforcement rotates to a specified angle; S4, after the longitudinal reinforcement conveying device 2 drives the longitudinal reinforcement to the designated position, the welding processing device moves the stirrup to the welding position and welds the stirrup to the longitudinal reinforcement; S5. After the stirrups and longitudinal bars are welded, the welding processing device cuts the welded stirrups and longitudinal bars.

[0053] Specifically, when a steel bar skeleton needs to be fabricated, the position of the longitudinal bar driver 212 is first adjusted using the support seat moving assembly 22, and the position of the bending mechanism 32 is adjusted using the bending moving assembly 31, so that the position of the longitudinal bar driver 212 is consistent with the position of the bending mechanism 32. Simultaneously, stirrups are placed on the stirrup placement seat 42, and the stirrup clamping assembly 43 clamps the stirrups so that they are stably placed on the stirrup placement seat 42. Furthermore, the position of the clamping rod 434 is adjusted so that the clamping rod 434 can support the longitudinal bars during their movement.

[0054] The longitudinal bar is then placed on the longitudinal bar driver 212 and the stop block 323, with the first bending point of the longitudinal bar at the stop block 323. The push wheel of the first bending member 324 moves a specified distance, pushing the longitudinal bar toward the stop block 323. Due to the restriction of the stop block 323, the longitudinal bar bends at a specified angle. After the first bending of the longitudinal bar, the push wheel of the first bending member 324 returns to the specified position and cooperates with the stop block 323 to limit the movement of the longitudinal bar, thereby improving the stability of the longitudinal bar during movement.

[0055] When the longitudinal bar reaches the second bending point at the push wheel of the first bending member 324, it stops moving. Simultaneously, the push wheel of the first bending member 324 presses against the longitudinal bar, reducing the possibility of further movement. Then, the push wheel of the second bending member 325 moves, pushing the longitudinal bar toward the first bending member 324. Under the restraint of the push wheel of the first bending member 324, the longitudinal bar undergoes a second bend.

[0056] After the longitudinal bar is bent twice, the longitudinal bar that needs to be adjusted in its bent section is clamped by the first bending member 324 and the second bending member 325 and rotated a specified angle under the drive of the bending rotating member 326. When the bending mechanism 32 no longer needs to adjust the longitudinal bar's direction, the push wheel of the second bending member 325 retracts a specified distance and cooperates with the limit block 323 and the first bending member 324 to limit the longitudinal bar's movement direction, thereby improving the stability of the longitudinal bar during movement.

[0057] The longitudinal bar driving member 212 drives the longitudinal bar to continue to move after being bent twice. After the longitudinal bar passes through the inner side of the stirrup, the position to be welded is moved to the welding device 5. At the same time, when the longitudinal bar moves to the designated position, the push wheels of the first bending member 324 and the push wheels of the second bending member 325 respectively press against the longitudinal bar, reducing the possibility of the longitudinal bar continuing to move.

[0058] When the welding point of the longitudinal reinforcement is moved to the welding device 5, the reinforcement removal member 443 moves the stirrup to the welding device 5. At this time, the welding gun 53 moves to weld the intersection of the stirrup and the longitudinal reinforcement.

[0059] After the first stirrup is welded to the longitudinal reinforcement, the reinforcement removal member 433 moves the welded first stirrup to the position of the discharge member 63. At this point, the discharge member 63 moves to clamp the first stirrup. Simultaneously, the reinforcement removal member 443 releases the first stirrup and moves to the stirrup placement seat 42 to clamp the next stirrup. As the reinforcement removal member 433 releases the first stirrup, the discharge support frame 61 moves, causing the discharge member 63 to move the welded first stirrup and simultaneously move the longitudinal reinforcement. The discharge support frame 61 stops moving when the next welding position of the longitudinal reinforcement reaches the welding device 5. At this point, the reinforcement removal member 443 moves the next stirrup to the welding device 5 for welding to the longitudinal reinforcement.

[0060] As the longitudinal bars are gradually moved, the reinforcement removal member 443 moves the stirrups to the position of the welding device 5 for welding, thereby finally forming a steel skeleton. During the welding process, the stirrups and longitudinal bars are placed on the discharge platform 64 after welding for easy discharge.

[0061] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
