Description

Technical Field

[0001] The present invention belongs to the technical field of metal processing equipment and the technical field of prefabricated buildings, and particularly relates to a serpentine reinforcement production device and a serpentine reinforcement production method. Background Art

[0002] Prefabricated buildings are rapidly gaining popularity in my country. Prefabricated concrete buildings are a key component of this type of construction. However, their current cost is relatively high compared to cast-in-place construction, hindering their development. Cost calculations indicate that the high production costs of prefabricated components are a significant factor contributing to the high cost of prefabricated concrete buildings. Reducing the cost of prefabricated component production has become crucial for lowering the cost of prefabricated concrete buildings and promoting their development.

[0003] At present, in concrete precast component factories, some processes, especially the steel bar production process, still involve a large amount of manual work, resulting in relatively high labor costs for component production; although some factories use mechanization in the steel bar production process, due to the complexity of the production process, even if mechanization is used and labor costs are saved, the machinery costs increase significantly, resulting in no significant reduction in overall costs.

[0004] Whether precast or cast-in-place, concrete components, floor slabs and wall panels, all involve mesh reinforcement, and their use is substantial. Existing mechanized production techniques typically involve straightening the bars, cutting them to preset lengths, processing individual bars, marking them, arranging them into a mesh, and spot welding them into a mesh. Even with mechanization, these processes are complex and require only individual rebars to be produced piece by piece. This results in complex production equipment and high operating costs, hindering widespread adoption. Summary of the Invention

It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth in order to fully understand the present invention. The embodiments described are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative work are within the scope of protection of the present invention.

[0106] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0107] Example 1

[0108] like Figures 1 to 41 As shown, this embodiment provides a serpentine reinforcement production device, including an equipment platform component 1, a reinforcement bending component 2 and a coiled reinforcement conveying component 3;

[0109] like Figures 7-13 As shown, the equipment platform assembly 1 includes a rotating table, a rotating support column 12, a platform base 13, a rotating drive device 14 and a platform integral tensioning device 15; the rotating table and the rotating support column 12 are connected as a whole, and the rotating support column 12 and the platform base 13 rotate in coordination; the rotating drive device 14 is fixed to the platform base 13, and the rotating drive device 14 is used to drive the rotating support column 12 and the rotating table to rotate; the rotating table is used to drive the bending bar assembly 2 to rotate together, so as to bend the steel bars into serpentine bars.

[0110] like Figures 7-13As shown, the rotating table includes a panel 111, a splicing hole 112, a steel bar locking member 113 and a steel bar end support member 114; the splicing hole 112 is provided on the panel 111, and is divided into a first splicing hole 1121 and a second splicing hole 1122, and is respectively used to correspondingly install the first bending bar assembly and the second bending bar assembly. The positions of the first bending bar assembly and the second bending bar assembly in their corresponding first splicing hole 1121 and second splicing hole 1122 can be adjusted to adapt to the size of the serpentine bar produced; a pressure plate slot 1111 is provided on both sides of the second splicing hole 1122, and a pressure plate 55 is installed on the pressure plate slot 1111. The pressure plate 55 presses the second bending bar assembly so that it can move in the second splicing hole 1122, but cannot escape from the second splicing hole 1122 upward;

[0111] The steel bar locking member 113 is provided at a preset position of the panel 111 and is provided with a steel bar locking area for simultaneously locking N steel bars (N is a positive integer and N≥1). In this embodiment, N=5, that is, 5 steel bars can be locked simultaneously.

[0112] The steel bar end support 114 is provided on the panel 111 and adjacent to the steel bar locking member 113, and is used to receive the steel bars passing through the steel bar locking member 113. In this embodiment, the steel bar end support 114 includes a support frame 1141, a plurality of layers of steel bar receiving channels 1142, frame integral moving rollers 1143, and frame moving guide rails 1144. The support frame 1141 is slidably engaged with the frame moving guide rails 1144 via the frame integral moving rollers 1143. The steel bar receiving channels 1142 are provided on the support frame 1141 and correspond to the locking steel bar area of ​​the steel bar locking member 113.

[0113] Before producing serpentine bars, for longer serpentine bars, N bars will pass through the bar locking member 113 when they are in place, so a bar end support 114 is required. In this embodiment, the bar receiving channel 1142 of the bar end support 114 is first inserted into the bar locking member 113 to receive each bar. The bar end support 114 and the received bars are then removed from the bar locking member 113, and the bar locking member 113 then secures the bars. The purpose of this approach is to ensure that each bar (five in this embodiment) is guided or received from the beginning to the end before it is initially positioned and locked, ensuring that each bar is neatly arranged and in order.

[0114] In the present invention, the specific methods of the steel bar locking member 113 and the steel bar end support member 114 are not limited, as long as the steel bars can be locked in an orderly manner.

[0115] like Figures 7-10As shown, the platform overall tensioning device 15 includes a base roller 151, a platform moving track 152, a tensioning spring 153, a spring support assembly 154 and a platform moving limiter 155; the spring support assembly 154 includes a traction member 1541, a ramp 1542, a slope top limiter 1543 and a connecting rod 1544; the platform base 13 is slidingly connected to the platform moving track 152 through the base roller 151, the platform moving limiter 155 is arranged on the platform moving track 152, the traction member 1541 is arranged on the inclined surface of the ramp 1542, the slope top limiter 1543 is arranged at the top of the ramp 1542, the traction member 1541 is connected to one end of the tensioning spring 153 through the connecting rod 1544, and the other end of the tensioning spring 153 is connected to the platform base 13.

[0116] The function of the platform overall tensioning device 15 is to keep the steel bars on the rotating table in a tensioned state by adjusting the overall position of the platform base 13 to prevent the steel bars from becoming disordered during the processing.

[0117] The working principle of the platform's overall tensioning device 15 is as follows: when the rotating table rotates, the steel bar bending point and the steel bar output end are in two situations: "farther away" and "closer" to each other. When the two are "farther away", the rotation of the rotating table pulls the steel bar, and the steel bar on the rotating table is tightened. When the two are "closer", the rotation of the rotating table causes the steel bar to loosen. At this time, the tensioning spring 153 is needed to "compensate" the pulling effect, pulling the platform base 13, the rotating table thereon, the bending bar assembly 2, etc. as a whole in the direction "away" from the steel bar output end to keep the steel bar taut. To maintain sufficient tension on the steel bar on the rotating table, it is only necessary to ensure that the tensioning spring 153 maintains sufficient tension when the platform base 13 as a whole moves to the position of the platform movement limiter 155 at the far end.

[0118] The function of the spring support assembly 154 is to adjust the distance between the spring support assembly 154 and the platform base 13 by moving the traction member 1541 on the ramp 1542, thereby adjusting the tension of the spring to avoid excessive fluctuations in the spring tension when the equipment platform assembly 1 moves back and forth. The principle is: when the rotating table rotates, if the bending point of the steel bar and the output end of the steel bar are in a "far away" situation, the rotation of the rotating table pulls the steel bar. At this time, the tension of the tensioning spring 153 increases as the rotating table pulls the steel bar, forcing the traction piece 1541 to climb upward along the ramp 1542, and the spring support assembly 154 approaches the platform base 13; on the contrary, when the bending point of the steel bar and the output end of the steel bar are in a "close" situation, the tension of the steel bar output end on the platform base 13 is reduced due to the relaxation of the steel bar. At this time, the tensioning spring 153 pulls the platform base 13 in the direction of "away from" the steel bar output end, the tension of the tensioning spring 153 is reduced, and the traction piece 1541 descends along the ramp 1542, so the spring support assembly 154 moves in the direction away from the platform base 13. This arrangement, on the one hand, can ensure that sufficient tensioning force can be applied to the platform base 13 when the tension of the tensioning spring 153 is at its minimum, and can also reduce the maximum tension of the tensioning spring 153 to avoid it applying excessive tensioning force to the steel bars on the rotating table through the platform base 13.

[0119] like Figures 14-22 As shown, in this embodiment, the bend assembly 2 includes a first bend assembly and a second bend assembly, which are detachably connected to the rotating table. The first and second bend assemblies have the same structure, including a bend column assembly 21, a bend column assembly support frame, and a lifting drive device 23. There are at least two bend column assemblies 21, and the spacing between them is uniform. Each bend column assembly 21 can be independently attached to and detached from the bend column assembly support frame. The number of lifting drives 23 corresponds to the number of bend column assemblies 21.

[0120] Specifically, the bent bar column assembly 21 includes a bent bar column 211, a steel bar guide groove 212, a toothed bar 213 and a bent bar column support plate 215. The toothed bar 213 is connected to the lower end of the bent bar column 211. The steel bar guide groove 212 includes a plurality of grooves and is provided on the upper side wall of the bent bar column 211. The number of grooves is N (N = the number of steel bars that can be locked by the steel bar locking member 113, in this embodiment N = 5). The bent bar column support plate 215 is provided at the top of the bent bar column 211. When the bent bar column 211 rises and is exposed above the rotating table, the steel bar guide groove 212 can be used to guide multiple steel bars to be accurately positioned when bent; the bent bar column assembly support frame includes an upper support plate 221, a lower support plate 222 and a connecting member 223, the connecting member 223 connects the upper support plate 221 and the lower support plate 222, and the connecting member 223 is used to connect or strengthen the upper and lower support plates 222. The present invention does not limit its practice, and it can just serve to connect or strengthen the upper and lower support plates 222. The upper support plate 221 is provided with an upper positioning hole 2211, and the lower support plate 222 is provided with a lower positioning hole 2221. The bent rib column 211 mates with the upper positioning hole 2211. The lifting drive device 23 includes a drive gear and a drive motor. The toothed bar 213 meshes with the drive gear, and the drive end of the drive motor is connected to the drive gear. The drive motor is located on the lower support plate 222. The toothed bar 213 mates with the lower positioning hole 2221, which provides positioning and lateral support for the toothed bar 213. When the drive gear rotates, it drives the toothed bar 213 up and down, thereby driving the bent rib column 211 up and down. The drive gear meshes with the toothed bar 213, and the drive motor drives the drive gear to rotate, thereby driving the toothed bar 213 to move up and down.

[0121] The assembly sequence for the rib bending assembly 2 is as follows: 1) The rib bending column support plate 215 is inserted from bottom to top onto the rib bending column 211, with the lugs 214 of the rib bending column 211 snapping into the lug slots 2151 of the rib bending column support plate 215. 2) The rib bending column assembly 21 is lowered into the rib bending column assembly support frame, with the toothed bar 213 inserted into the lower positioning hole 2221 of the lower support plate 222. The rib bending column support plate 215 is installed and supported in the upper positioning hole 2211 of the upper support plate 221. 3) The lifting drive unit 23 is installed. The lifting drive unit 23 is mounted at a predetermined position on the lower support plate 222, with the drive gear of the lifting drive unit 23 tightly engaged with the toothed bar 213 of the rib bending column assembly 21.

[0122] In this embodiment, the cross-section of the rib column 211 is circular, and the cross-section of the toothed bar 213 is square. However, the present invention is not limited to the cross-sectional shapes of the rib column 211 and the toothed bar 213. It is sufficient that the dimensions of the rib column 211 match the spacing of the serpentine ribs to be produced, and that the cross-sectional shapes and dimensions of the rib column 211 and the toothed bar 213 match the shapes and dimensions of the openings of the rib column support plate 215 and the lower support plate 222 of the rib column assembly support frame.

[0123] like Figures 23-31 As shown, the coiled rebar conveying assembly 3 includes a coiled rebar holder 31, a rebar tensioning device, and a rebar conveying guide assembly; the rebar tensioning device is connected to the coiled rebar holder 31, and the rebar conveying guide assembly is arranged between the coiled rebar holder 31 and the rotating table; the coiled rebar holder 31 is used to place the coiled rebar, the rebar tensioning device is used to tighten the rebar, and the rebar conveying guide assembly is used to move in the same direction as the bending assembly 2 (the bending assembly 2 that is bending the rebar) so that the angle between the rebar and the initial axis O-O' during the bending process is within a preset range, so as to ensure that the relative position between the rebar and the next rebar bending column 211 to be raised is accurate before it is raised. In this embodiment, the angle between the rebar and the initial axis O-O' during the rebar bending process is 90°, but in actual implementation, the angle between the rebar and the initial axis O-O' can be close to 90° (e.g., 85° to 95°) to achieve the purpose of not causing confusion during the bending of the rebar and the rebar bending column being on the preset side of the rebar when it is raised.

[0124] like Figures 23-26 As shown, the steel bar tensioning device includes a connecting cylinder 321 , a base cylinder 322 , an annular friction plate 323 and a helical tensioning spring 324 . The relationship between them is as follows: the connecting cylinder 321 is rotatably connected to the coiled steel bar support 31 and the base cylinder 322 respectively, the coiled steel bar support 31 is provided with a bottom cover plate 311, and the connecting cylinder 321 is provided with an intermediate cover plate 3211. The annular friction plate 323 includes an upper friction plate leaf 3231 and a lower friction plate leaf 3232. The upper friction plate leaf 3231 and the lower friction plate leaf 3232 are respectively annularly fixed on the bottom cover plate 311 of the coiled steel bar support 31 and the intermediate cover plate 3211 of the connecting cylinder 321; the positions of the upper friction plate leaf 3231 and the lower friction plate leaf 3232 correspond to each other and are pressed against each other to provide friction force. The spiral tensioning spring 324 is sleeved on the base cylinder 322, and its two ends are respectively connected to the intermediate cover plate 3211 of the connecting cylinder 321 and the bottom plate of the base cylinder 322. The base cylinder 322 is fixed, and the connecting cylinder 321 and the coiled steel bar support 31 are rotatable.

[0125] The working principle is as follows: When the coiled rebar 6 is pulled out, the coiled rebar holder 31 rotates. The friction force of the annular friction plate 323 drives the connecting cylinder 321 to rotate. As the connecting cylinder 321 rotates, the helical tensioning spring 324 gradually tightens. When the helical tensioning spring 324 reaches a predetermined force, the annular friction plate 323 reaches its limit of friction. As the coiled rebar is further pulled out, the rotation of the coiled rebar holder 31 is no longer able to drive the connecting cylinder 321, causing relative displacement between the upper and lower friction plate lobes 3231 and 3232. Due to the action of the helical tensioning spring 324 and the annular friction plate 323, the coiled rebar holder 31 continuously experiences the "torque" of reverse rotation, thereby tightening the coiled rebar.

[0126] like Figures 27-31 As shown, the steel bar conveying guide assembly includes a guide wheel group 331, a guide wheel group placement frame 332, a track frame 333, a guide wheel drive device 334 and a drive controller 335. The guide wheel group 331 is a number of rotatable rollers, which are divided into N layers (N = the number of steel bars that can be locked by the steel bar locking member 113, in this embodiment N = 5), and each layer includes at least one pair of rollers. When the steel bars are conveyed or guided, one steel bar passes between the two rollers of each layer. The guide wheel group 331 has a limiting effect on the coiled steel bars. When the guide wheel group 331 moves as a whole, the position of the coiled steel bars is driven to move accordingly; at the same time, the guide wheel group 331 also has the function of conveying steel bars. When the rollers of the guide wheel group 331 clamp the coiled steel bars and rotate, they can drive the coiled steel bars to be output. The guide wheel group 331 of this embodiment has a total of 5 layers, 3 pairs of rollers on each layer, and the coiled steel bars of each layer are located between two rollers. The guide wheel assembly 331 is mounted on a guide wheel assembly rack 332 in a stacked configuration. The guide wheel assembly rack 332 is reciprocating within the track frame 333. The guide wheel assembly rack 332 is equipped with wheels on the sides and bottom, and the side wheels press against the side walls of the track frame 333. The guide wheel assembly rack 332 is connected to a guide wheel drive device 334 and a drive controller 335.

[0127] The present invention does not limit the number and method of the rollers, nor does it limit the specific method of driving the rollers to rotate and thereby drive the steel bars to be output.

[0128] The drive controller 335 includes a connecting base 3351, a control base 3352, an arm bracket 3353, and an arm member 3354. The arm members 3354 are stacked together, with the coiled steel bar clamped between two arm brackets 3354, which are fixed to the arm brackets 3353. The arm brackets 3353 are rotatably coupled to the connecting base 3351. The control base 3352 is mounted on the connecting base 3351. The control base 3352 is provided with a conductive area and a power-off area. One end of the arm bracket 3353 is provided with a conductor and is located in the conductive area or the power-off area. The guide wheel drive device 334 is connected to the conductive area of ​​the control base 3352 and the arm bracket 3353. The conductor is electrically connected. Specifically, the conductor can serve as an electrode of the circuit of the guide wheel driving device 334. The end of the arm frame 3353 is in close contact with the control base 3352; the control base 3352 is fixed on the connecting base plate 3351 and is in close contact with the end of the arm frame 3353. The contact surface between the control base 3352 and the end of the arm frame 3353 is divided into three sections according to different methods: the middle section is an insulator, and the two side sections are provided with conductors. The two side sections can serve as another electrode of the circuit of the guide wheel driving device 334.

[0129] The operating principle of the drive controller 335 is as follows: the drive controller 335 is fixed to the top of the guide wheel assembly mounting frame 332 and moves with the guide wheel assembly 331. During the bending process, the coiled rebar drives the clamping arm 3354 and the clamping arm frame 3353 to swing. When the coiled rebar output end is oblique to the initial axis O-O' and tilted in a certain direction, the coiled rebar drives the clamping arm frame 3353 to swing in that direction, thereby triggering the circuit connecting the end of the clamping arm frame 3353 to the control base 3352 to connect, and the guide wheel drive device 334 to operate and drive the guide wheel assembly mounting frame 332 and the guide wheels therein in that direction. When the coiled rebar is perpendicular to the initial axis O-O' and the clamping arm frame 3353 returns to the middle position, the circuit between the end of the clamping arm frame 3353 and the control base 3352 is disconnected (because the middle section of the contact surface of the control base 3352 is insulated), the guide wheel drive device 334 is disconnected, and the guide wheel assembly 331 does not move. The driving controller 335 is used to dynamically adjust the angle between the coiled steel bar and the initial axis OO' so that the output end of the coiled steel bar remains substantially perpendicular to the initial axis OO' during the bending process.

[0130] The guide wheel drive device 334 of the present invention includes a driving power device and a traction line. Since the technology for pulling a specific component in a fixed direction is very mature, the present invention does not limit the specific method of the guide wheel drive device 334. It only needs to be able to pull the guide wheel back and forth under the control of the drive controller 335.

[0131] like Figures 32-35As shown, the serpentine tendon disengagement device 5 is also included. The serpentine tendon disengagement device 5 includes a turnbuckle 51, a gear member 52, a clamping plate 53, and a pulling rope 54. The turnbuckle 51 includes a first screw rod 511, a second screw rod 512, and a nut 513. The first screw rod 511 is fixed to the inner side of the splicing groove 112, and the second screw rod 512 is connected to the clamping plate 53. The clamping plate 53 is clamped into the upper support plate 221 of the support frame of the bent tendon column assembly. The gear member 52 is fixed to the outer side of the nut 513 of the turnbuckle 51. The pulling rope 54 engages with the gear member 52. Pulling the pulling rope 54 can pull the nut 513 to rotate. The threads of the first screw rod 511 and the second screw rod 512 of the turnbuckle 51 are opposite to each other. When the nut 513 rotates, the first screw rod 511 and the second screw rod 512 can be screwed in or out of the nut 513 at the same time.

[0132] In practice, when the serpentine bar is produced, it is clamped into the rebar guide groove 212 on the bent column assembly 21. By pulling the pulling rope 54 manually or using a pulling device, the nut 513 of the turnbuckle 51 is rotated, forcing the first screw 511 and the second screw 512 of the turnbuckle 51 to simultaneously screw into the nut 513. The clamping plate 53 of the second screw 512 pulls the bent column assembly support frame, thereby pulling the bent column assembly 21 and the serpentine bar apart, achieving the purpose of removing the serpentine bar from the rebar guide groove 212 on the bent column assembly 21.

[0133] In this embodiment, the pulling rope 54 is manually pulled, but the present invention is not limited to manual operation, and an electric operation can also be used. Since the technology of electrically driving the pulling rope 54 is very mature, the present invention does not make any specific limitation.

[0134] like Figures 36-41As shown, the steel bar guiding assembly 4 includes a steel bar channel hanger 41, a hanger opening and closing drive device 42, a drive device fixing frame 43, a steel bar channel group 44 and an opening spring 45. Among them, there are N steel bar channel groups 44 (N=the number of steel bars that can be locked by the steel bar locking member 113, in this embodiment N=5), the steel bar channel hanger 41 includes a left hanger and a right hanger, each steel bar channel group 44 is divided into a left half channel group 441 and a right half channel group 442, which are respectively fixed to the left hanger and the right hanger, the hanger opening and closing drive device 42 is connected to the drive device fixing frame 43, the drive end of the hanger opening and closing drive device 42 is provided with a pulling wire, which is respectively connected to the left hanger and the right hanger, and the opening spring 45 is arranged between the left hanger and the right hanger, The pulling wire cooperates with the opening spring 45. When the pulling wire is tightened, the steel bar channel hanger 41 is closed. When the pulling wire is relaxed, the opening spring 45 acts to open the steel bar channel hanger 41. The height position of the left half channel group 441 and the right half channel group 442 of each steel bar channel after closing is the same as the height position of the output of each layer of coiled steel bars, the height position of each layer of steel bars in the steel bar locking member 113, the height position of each layer of steel bar receiving channel 1142 of the steel bar end support member 114, and the height position of each layer of steel bar guide groove 212 in the bent bar column assembly 21.

[0135] In specific implementation, when the hanger opening and closing drive device 42 rotates and tightens the pulling wire, the left hanger and the right hanger of the steel bar channel hanger 41 are closed, so that the left half channel group 441 and the right half channel group 442 of the steel bar channel are closed to form a complete steel bar channel.

[0136] The whole process of steel bar placement is as follows: after each layer of steel bars is output from the coiled steel bar conveying assembly 3, it immediately enters the steel bar channel group 44 after the steel bar positioning assembly 4 is closed, and follows the steel bar channel group 44 to reach the steel bar locking member 113. At this time, the steel bar receiving channel 1142 of the steel bar end support 114 has extended into the steel bar locking member 113 to receive the steel bar. After the steel bar is fully received, the steel bar receiving channel 1142 of the steel bar end support 114 exits the steel bar locking member 113; when the steel bar passes the steel bar locking member 113 and reaches the preset length, the steel bar stops being output; the steel bar locking member 113 locks the steel bar, and at this time the steel bar is completed and initially in place. Then the hanger opening and closing driving device 42 rotates in the opposite direction and relaxes the pulling wire. Under the action of the opening spring 45, the left hanger and the right hanger of the steel bar channel hanger 41 are opened. After opening, the lowest height of the steel bar channel hanger 41 is higher than the lowest height of all rotating parts during the serpentine bar processing, so that the opened steel bar channel hanger 41 does not hinder the processing of the serpentine bar.

[0137] The serpentine reinforcement production equipment of the present application also includes an electric control module, ① controlling the rotary drive device 14 through the electric control module to rotate the rotary drive device 14, thereby driving the rotary support column 12 and the rotating table to rotate forward or reverse; ② controlling the steel bar end support 114 through the electric control module to move the steel bar end support 114 into the steel bar locking member 113 to receive the steel bar and move out of the steel bar locking member 113 after completing the receiving of the steel bar; ③ controlling the steel bar locking member 113 through the electric control module to press or loosen the steel bar; ④ controlling each lifting drive device 23 of the bending reinforcement assembly 2 through the electric control module to drive the bending reinforcement column 211 to rise and fall. ⑤ The guide wheel group 331 of the steel bar conveying guide assembly is controlled by the electronic control module to make the guide wheel group 331 press or loosen the steel bar. When the guide wheel group 331 presses the steel bar, the guide wheel group 331 is driven to rotate in a preset direction to drive the steel bar to be output in a preset direction; ⑥ The guide wheel driving device 334 is controlled by the electronic control module to pull the guide wheel group placement frame 332 and the guide wheel group 331 placed therein to move as a whole; ⑦ The hanger opening and closing drive device 42 is controlled by the electronic control module to tighten the pulling wire or loosen the pulling wire, thereby driving the steel bar channel hanger 41 to open and close.

[0138] The process of producing serpentine rebar using the serpentine rebar production equipment is as follows: based on the length, width, and spacing parameters of the serpentine rebar to be produced, the number and spacing of the bending rebar components 2, the distance between the first and second bending rebar components, and the diameter of the coiled rebar are determined. The serpentine rebar production equipment is first placed in its initial state, with the rebar output in place and locked. After production begins, the first bending rebar column 211 is raised, and the rotating table rotates 180°, thereby causing the rebar to bend 180° around the first bending rebar column 211. Then, the second bending rebar column 211 is raised, and the rotating table rotates 180° in the opposite direction, causing the rebar to bend 180° in the opposite direction around the second bending rebar column 211. Using the same method, the rebar is continuously bent to the preset size to complete the serpentine rebar production.

[0139] The following briefly describes the production process of serpentine reinforcement:

[0140] 1) Select the bending bar assembly 2 according to the parameters of the serpentine bar to be produced: Determine the number and spacing of the bending bar assemblies 2, the distance between the first bending bar assembly and the second bending bar assembly, and the diameter of the coiled steel bar based on the length, width, spacing and other parameters of the serpentine bar to be produced; Install the bending bar assembly 2; Select the length of the second screw 512 of the serpentine bar release device 5 and install the serpentine bar release device 5.

[0141] 2) The rebar guide assembly 4 is closed, and the rebars of each layer are driven out by the coiled rebar conveyor assembly 3. The rebars follow the closed rebar channel of the rebar guide assembly 4 to the rebar locking member 113 and enter the rebar receiving channel 1142 of the rebar end support member 114. After the rebars pass through the rebar locking member 113 and reach the preset length, they are locked. The rebar channel hanger 41 opens. This completes the rebar delivery and initial positioning.

[0142] 3) The bent bar columns 211 are raised one by one. Each time a bent bar column 211 is raised, the rotating table rotates 180° or 180° in the opposite direction, driving each layer of steel bars to bend 180° around the newly raised bent bar column 211. During the steel bar bending process, each layer of steel bars is accurately positioned under the guidance of the steel bar guide groove 212, and finally the production of multiple layers of serpentine bars is completed at the same time.

[0143] 4) Pull the pulling rope 54 of the serpentine bar disengaging device 5, forcing the nut 513 of the basket screw 51 to rotate, and the first screw 511 and the second screw 512 of the basket screw 51 are screwed into the nut 513, thereby pulling the bent bar column assembly 21 to separate from the serpentine bar, and the serpentine bar is disengaged from the steel bar guide groove 212.

[0144] During the serpentine rebar production process, the platform's integral tensioning device 15 generates a tensioning force to keep the rebar on the rotating table taut. The rebar tensioning device of the coiled rebar conveyor assembly 3 also applies tensioning force to the rebar at the output end, forcing it to remain taut. Maintaining the tensioned rebar prevents confusion when processing multiple layers of rebar simultaneously.

[0145] Example 2

[0146] like Figure 44 As shown, this embodiment provides a mesh rib with serpentine ribs, and the serpentine ribs are produced by the serpentine rib production equipment of embodiment 1;

[0147] The two serpentine ribs 71 and 72 are stacked and connected alternately to form a mesh rib.

[0148] Example 3

[0149] like Figure 45 As shown, this embodiment provides a method for producing the serpentine rib of embodiment 1, comprising the following steps:

[0150] S1: Determine the bending bar assembly 2 according to the preset diameter, spacing Δ, and width W of the serpentine bar (the diameter, spacing, and number of the bending bar columns 211 are determined accordingly); install the first bending bar assembly and the second bending bar assembly on the first splicing slot 1121 and the second splicing slot 1122 on the rotating table; determine the spacing L between the first bending bar assembly and the second bending bar assembly according to the preset length L of the serpentine bar, and install the bending bar assemblies;

[0151] S2: Select the coiled steel bar according to the preset diameter of the serpentine bar and place the coiled steel bar on the coiled steel bar support;

[0152] S3: The positions of the equipment platform component 1, the bending bar component 2, and the coiled steel bar conveying component 3 are set to the initial state; at this time, all the bending bar columns 211 are in the non-raised state;

[0153] S4: The steel bar channel of the guiding steel bar positioning assembly 4 is closed, and the coiled steel bar 6 enters the steel bar locking member 113 through the steel bar channel under the action of the coiled steel bar conveying assembly 3 and is locked; the steel bar channel is opened to complete the initial positioning of the steel bar;

[0154] S5: The first bent column 211 rises and extends out of the rotating table to a preset height;

[0155] S6: The rotating table drives the bending assembly 2 to rotate in a direction that forces the steel bar to bend around the first bending column 211 until it rotates 180°; the steel bar conveying guide assembly drives the coiled steel bar to move in the same direction as the bending assembly 2, so that the angle between the steel bar and the initial axis O-O' during the bending process is within a preset range;

[0156] S7: The next bending column 211 is raised and extends out of the rotating table to a preset height;

[0157] S8: The rotating table drives the bending assembly 2 to rotate in a direction that forces the steel bar to bend around the newly raised bending column 211 until it rotates 180°; the steel bar conveying guide assembly drives the coiled steel bar to move in the same direction as the bending assembly 2, so that the angle between the steel bar and the initial axis O-O' during the bending process is within a preset range;

[0158] S9: Repeat S7 to S8 until the production of the serpentine reinforcement is completed according to the preset size.

[0159] In this embodiment, the angle between the steel bar and the initial axis O-O' is 90°. During specific implementation, when the steel bar conveying guide assembly drives the coiled steel bar to move in the same direction as the bending bar assembly 2, it is only necessary to make the angle between the steel bar and the initial axis O-O' within a preset range (such as 85°~95°), and when bending to 180°, the relative position of the steel bar and the next bending bar column to be raised is correct, so as to achieve the purpose of no confusion when the steel bar is bent and the bending bar column being on the preset side of the steel bar when it is raised. It is not stipulated that the steel bar must be completely perpendicular to the initial axis O-O' during the bending process.

[0160] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Therefore, any modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of the technical solution of the present invention.
