[0002] In recent years, with the implementation of major national engineering projects, profiled steel arches have been widely used in projects such as tunnels, subway stations, hydropower stations, and underground chambers. In the construction of tunnels, subway stations, hydropower stations, and underground chambers, a large amount of cold-formed profiled steel is required to make profiled steel arches to improve the strength of buildings. However, the current profiled steel forming equipment has low automation, high labor intensity, and low production efficiency when facing mass production, which cannot meet the market demand. Based on this situation, it is necessary to design a high-efficiency automatic forming production line for profiled steel from raw materials to forming. The production line is an automatic production line integrating automatic feeding, automatic continuous connection, automatic forming, fixed-length cutting, material transfer and preparation, finished product stacking, etc.

[0046] The following details various non-limiting embodiments of the present invention with reference to the accompanying drawings.

[0047] Please refer to Figures 1 - 17, An automatic forming production line for profiled steel provided by an embodiment of the present invention, which mainly consists of a feeding mechanism 1, a feeding mechanism 2, a cutting mechanism 3, a connecting mechanism 4, a forming mechanism 5, a cutting-off mechanism 6, a material-transferring and stockpiling mechanism 7, a welding mechanism 8, and a storage mechanism 9 that are sequentially installed along the traveling direction of the profiled steel.

[0048] Specifically, in the present invention, the traveling direction of the profiled steel refers to the traveling direction of the profiled steel on this automatic forming production line for profiled steel during operation; through the automatic forming production line for profiled steel provided by the present invention, the original operation mode during profiled steel production is changed, the number of workers is reduced, the labor intensity of the workers is lowered, and by adopting automated operation instead of manual labor, the injury accidents caused to workers during profiled steel processing are reduced. At the same time, the automatic forming production line for profiled steel has a high degree of automation, can make the profiled steel products unified and standardized, can improve the product precision, and also greatly improves the production efficiency of the enterprise.

[0049] Furthermore, in one embodiment, for the automatic forming production line for profiled steel, the feeding mechanism 1 includes a feeding rack 11, an alignment device 12 installed at the front end of the feeding rack 11, and alignment plates 13 and alignment cylinders 14 installed on both sides of the feeding rack 11 and on the side near the alignment device 12.

[0050] Among them, the alignment device 12 includes a support plate 121 rotatably connected to the front end of the feeding rack 11 and a telescopic cylinder 122 installed at the bottom of the support plate 121 and connected to the lower end of the feeding rack 11. A support rotating shaft 123 and a limit rotating shaft 124 are also installed on the support plate 121.

[0051] Specifically, a platform 15 is also installed on one side of the feeding rack 11, which provides a platform for workers to make the operating height appropriate and facilitate work operations; the feeding rack 11 is used to provide storage for raw materials.

[0052] During operation, the bundled raw materials are placed on the feeding rack 11. Workers stand on the platform 15, divide the bundled raw materials into individual profiled steels, roll the profiled steels onto the alignment device 12 through tools. Due to the self-gravity of the profiled steel or manual pushing, the profiled steel is aligned along the side of the limit rotating shaft 124 of the alignment device 12. Then, after the alignment cylinder 14 extends to tightly hold the profiled steel against the alignment plate 13, the alignment device 12 contracts and descends through the telescopic cylinder 122 to place the profiled steel on the first horizontal feeding device 21.

[0053] Furthermore, in one embodiment, for the automatic forming production line for profiled steel, the feeding mechanism 2 includes a first horizontal feeding device 21 and a material-transferring device 22 installed on the side of the first horizontal feeding device 21 away from the feeding mechanism 1.

[0054] Among them, the material transfer device 22 includes a material transfer support 221, two material transfer rotating shafts 222 installed on the material transfer support 221, two rotating arms 223 respectively connected to the two material transfer rotating shafts 222, and a material transfer rod 224 rotatably connected to the two rotating arms 223. The material transfer device 22 further includes a transfer table 225 and a first correction cylinder 226 installed on the material transfer support 221, and a material transfer motor 227 installed inside the material transfer support 221. The material transfer motor 227 is used to drive the two material transfer rotating shafts 222 to rotate.

[0055] Specifically, the first horizontal feeding device 21 feeds materials horizontally through a chain; the first correction cylinder 226 achieves correction by using a cylinder to press and align; the material transfer motor 227 drives a chain through a sprocket to provide rotational power, thereby driving the two material transfer rotating shafts 222 to rotate; the material transfer device 22 adopts a parallelogram mechanism to realize material transfer between different heights, that is, the two rotating arms 223, the material transfer rod 224, and the two material transfer rotating shafts 222 form a quadrilateral rotating device. The material transfer rod 224 provides support for holding the material, and the transfer table 225 provides a transfer transition platform.

[0056] During operation, the material transfer motor 227 starts, drives the two material transfer rotating shafts 222 to rotate through a chain. The two rotating arms 223 are respectively fixed on the two material transfer rotating shafts 222, forming a parallelogram with the material transfer rod 224, ensuring that the material transfer rod 224 horizontally holds up the section steel during rotation. After rotating along the two rotating arms 223, the section steel on the first horizontal feeding device 21 is transferred to the transfer table 225, and the section steel on the transfer table 225 is transferred to the first line body 33 in the cutting mechanism 3, and so on for cyclic material transfer; when the section steel is transferred to the first line body 33, the first correction cylinder 226 extends, pushing the section steel against the first limit roller 334 to correct the section steel and facilitate the section steel to move forward and backward on the first line body 33.

[0057] Further, in an embodiment, the section steel automatic forming production line, wherein the cutting mechanism 3 includes a limit frame 31, a first sawing machine 32, a first line body 33, a second sawing machine 34, and a second line body 35 installed in sequence;

[0058] Among them, the first line body 33 includes a first line body frame 331. A first baffle 332, a first walking support roller 333, and a first limit roller 334 are installed on the first line body frame 331. The first line body 33 further includes a first walking motor 335 installed on the first line body frame 331. The first walking motor 335 is used to drive the first walking support roller 333 to rotate;

[0059] The second line body 35 includes a second line body frame 351, on which a second baffle 352, second walking rollers 353, second limit rollers 354 and a second correction cylinder 356 are installed. The second line body 35 further includes a second walking motor 355 installed on the second line body frame 351, and the second walking motor 355 is used to drive the second walking rollers 353 to rotate.

[0060] Specifically, the first walking motor 335 drives the first walking rollers 333 to rotate through a chain, thereby driving the section steel to move. The forward and reverse rotation of the first walking motor 335 drives the section steel to move forward and backward. The first baffles 332 on both sides limit the position of the section steel to prevent it from tilting out of the line body. The first limit rollers 334 serve as both a reference limit and prevent the section steel from rubbing against the first baffles 332, making the movement of the section steel smoother. Among them, the limit frame 31 prevents sudden accidents when the section steel moves towards the first sawing machine 32, restricts the position of the section steel, and plays a protective role. Among them, in the second line body 35, the second correction cylinder 356 achieves correction by the way of the cylinder pushing and aligning, and the functions of the remaining structures are the same as those of the structures on the first line body 33.

[0061] During operation, when the section steel enters the first line body 33 from the feeding mechanism 2, the first correction cylinder 226 extends its cylinder, pushing the section steel against the first limit rollers 334 to make the section steel flush with the reference. Then the first walking motor 335 drives the first walking rollers 333 to rotate, driving the section steel towards the first sawing machine 32. After arriving, the first sawing machine 32 cuts off one end of the blank of the section steel. Then the first walking motor 335 rotates in the reverse direction, making the section steel move towards the second sawing machine 34. After arriving, the second sawing machine 34 cuts off the other end of the blank of the section steel, making both ends of the section steel neat, which is convenient for the alignment and welding of the section steel. Among them, the movement mode of the second line body 35 is the same as that of the first line body 33. When both ends of the section steel are cut, the first line body 33 sends the section steel to the second line body 35. After the section steel reaches the appropriate position, the cylinder of the second correction cylinder 356 extends, correcting the section steel to make it flush with the reference, which is convenient for entering the splicing mechanism 4 later.

[0062] Further, in one embodiment, the automatic section steel forming production line, wherein the connecting mechanism 4 includes a connecting machine base 41 and a first automatic welding robot 42 installed on one side of the connecting machine base 41. At both ends of the top of the connecting machine base 41, a feeding roller 43 and a discharging roller 44 are respectively installed. Between the feeding roller 43 and the discharging roller 44 on the top of the connecting machine base 41, a feeding horizontal clamping device 45, a feeding vertical pressing device 46, a discharging vertical pressing device 47 and a discharging horizontal clamping device 48 are sequentially installed. Among them, a stopper 49 is further provided on the connecting machine base 41 near the discharging roller 44. A collecting box 40 is detachably installed between the feeding vertical pressing device 46 and the discharging vertical pressing device 47 on the top of the connecting machine base 41.

[0063] Specifically, the connecting machine base 41 provides an installation position and support. When the section steel enters the connecting mechanism 4, the feeding roller 43 provides guidance and support to facilitate feeding. The feeding horizontal clamping device 45 provides horizontal positioning after the feeding is in place. The feeding vertical pressing device 46 provides vertical positioning for the feeding. The discharging vertical pressing device 47 provides vertical positioning for the section steel at the docking end. The discharging horizontal clamping device 48 provides horizontal positioning for the docking end. The discharging roller 44 provides guidance and support for the docking section steel. The stopper 49 adjusts the position of the cold bending structure 54 in the forming mechanism 5 through distance sensing, so that the section steel at the docking end is always kept flush for convenient docking. After the docking is completed, the first automatic welding robot 42 is used for automatic welding. The collecting box 40 is arranged at the bottom of the docking end of the two section steels and is used for collecting the welding chips generated during the automatic welding of the first automatic welding robot 42, which is beneficial to centralized treatment after collection. The collecting box 40 is detachably connected to the top of the connecting machine base 41, which is convenient for the removal and installation of the collecting box 40. Among them, the specific structures of the feeding horizontal clamping device 45 and the discharging horizontal clamping device 48 in this embodiment are not limited here, as long as they can realize the horizontal clamping (positioning) function for the feeding section steel and the section steel at the docking end (discharging), for example, it can be realized by a horizontally arranged hydraulic cylinder connecting a fixing plate (contacting the side of the section steel) to achieve the horizontal positioning function for the feeding section steel and the section steel at the docking end (discharging). Similarly, the specific structures of the feeding vertical pressing device 46 and the discharging vertical pressing device 47 in this embodiment are not limited here, as long as they can realize the vertical clamping (positioning) function for the feeding section steel and the section steel at the docking end (discharging), for example, it can be realized by a vertically arranged hydraulic cylinder connecting a fixing plate (contacting the top of the section steel) to achieve the vertical positioning function for the feeding section steel and the section steel at the docking end (discharging).

[0064] During operation, the profiled steel enters the feeding horizontal clamping device 45 and the feeding vertical pressing device 46 through the guiding of the feeding idler roller 43. After reaching the butt joint position, the feeding horizontal clamping device 45 and the feeding vertical pressing device 46 are respectively tightened to firmly fix the profiled steel. The butt joint profiled steel on the other side is fixed by the discharging vertical pressing device 47 and the discharging horizontal clamping device 48. After being fixed, the first automatic welding robot 42 welds the butt joint position.

[0065] Further, in one embodiment, for the profiled steel automatic forming production line, the forming mechanism 5 includes a forming machine base 51. A sliding platform 52 is fixedly installed on the forming machine base 51. One end of the sliding platform 52 is rotationally connected to a cold bending structure 54 through a rotating structure 53. The rotating structure 53 includes a forming rotating shaft 531 arranged on the sliding platform 52 and a sliding plate 532 fixedly connected thereto. The sliding plate 532 is connected to the sliding platform 52 through a rolling structure 55. The other end of the sliding platform 52 is connected to the sliding plate 532 through a first adjusting structure 56.

[0066] Among them, the rolling structure 55 is a plurality of bull eye universal beads laid on the lower surface of the sliding plate 532 or the upper surface of the sliding platform 52. The first adjusting structure 56 is a turbo screw jack. One end of the turbo screw jack is connected to the sliding platform 52, and the other end is connected to the sliding plate 532. Through the screw drive of the turbo screw jack, the cold bending structure 54 can be driven to rotate and adjust around the forming rotating shaft 531 on the sliding platform 52.

[0067] The cold bending structure 54 includes a cold bending base 541 arranged on the sliding plate 532, forming roller devices 542 arranged at both ends on the cold bending base 541, and a first jacking device 543 arranged on the cold bending base 541 between the two forming roller devices 542. The forming roller device 542 includes a forming roller 5421 arranged on the cold bending base 541 and a forming motor 5422 connected to the forming roller 5421. The forming motor 5422 is a motor with a brake. The first jacking device 543 includes a hydraulic cylinder 5431 arranged on the cold bending base 541, a hydraulic rod 5432 arranged in the hydraulic cylinder 5431, and a jacking frame 5433 connected to the jacking end of the hydraulic rod 5432.

[0068] The cold bending structure 54 further includes a vertical limiting device 544 installed on the cold bending base 541 for limiting the position of the profiled steel in the vertical direction. A positioning scale 545 is installed on the cold bending base 541 on the side of the jacking frame 5433. A sizing device 546 is also installed on the cold bending base 541. The sizing device 546 is provided with rollers that are in rolling contact with the side surface of the profiled steel.

[0069] Specifically, the forming mechanism 5 is a device for forming a straight profiled steel into a required arc. The forming machine base 51 provides an installation position. The first adjustment structure 56 is used to push the sliding plate 532 (thereby driving the cold bending structure 54) to rotate and adjust around the forming rotating shaft 531 on the sliding platform 52, so as to adjust the position of the cold bending structure 54, ensuring that the butt joint reference surface of the profiled steel in the previous connecting mechanism 4 remains unchanged and always remains flush, facilitating butt joint, thus ensuring the butt joint effect of the profiled steel and guaranteeing the preparation process of the profiled steel. Specifically, the horizontal distance between the limiter 49 in the connecting mechanism 4 and the outgoing connecting profiled steel (i.e., the incoming profiled steel to be cold bent and formed in the forming mechanism 5) is sensed to control the first adjustment structure 56 to adjust the position of the cold bending structure 54, thereby ensuring that the butt joint reference surface of the profiled steel in the connecting mechanism 4 remains unchanged, thus ensuring the welding effect and guaranteeing the preparation process of the profiled steel. Among them, the vertical limiting device 544 is used to limit the position of the profiled steel in the vertical direction. The jacking frame 5433 in the first jacking device 543 is used to tightly hold the profiled steel to make it cold bent and formed. The positioning scale 545 is installed on its side, and the length of the extension of the jacking frame 5433 can be judged according to the positioning scale 545 to ensure the radius requirement of the required profiled steel. In the profiling roller device 542, the profiling roller 5421 drives the roller to rotate through the profiling motor 5422. The profiling motor 5422 is a motor with a brake to prevent the profiled steel from rolling after positioning, facilitating butt joint. The profiling roller 5421 not only provides single-sided positioning but also provides the driving force for the profiled steel to move forward. The sizing device 546 measures the arc length by the number of turns of the roller on it. When the measured arc length of the sizing device 546 meets the requirements, the third saw 65 in the cutting mechanism 6 cuts the profiled steel.

[0070] During operation, the profiled steel enters the vertical limiting device 544 and the two forming roller devices 542. The vertical limiting device 544 restricts its vertical direction, and the two forming roller devices 542 restrict one side of the profiled steel in the horizontal direction. The other side of the profiled steel is restricted by the first lifting device 543 extending out of the lifting frame 5433 to press tightly against the profiled steel. By adjusting the extending length of the lifting frame 5433, the required bending radian of the profiled steel can be adjusted. After reaching the required radian, the lifting frame 5433 keeps the telescopic length unchanged. The two forming roller devices 542 rotate and drive the profiled steel to move forward smoothly and slowly through friction, realizing the continuous bending effect of the profiled steel. During bending, the position of the cold bending structure 54 is adjusted by the positioner 49 sensing its horizontal distance from the profiled steel to ensure that the butt joint reference surface of the profiled steel in the continuous connection mechanism 4 remains unchanged. When the operation is completed, the two forming roller devices 542 stop rotating, and the lifting frame 5433 retracts.

[0071] Further, in one embodiment, for the automatic profiled steel forming production line, the cutting mechanism 6 includes a fixed base 61. A linear rail 62 is provided on the fixed base 61. A slider 63 matching the linear rail 62 is slidably connected to the linear rail 62. A third sawing machine 65 is connected to the slider 63 through a rotating device 64. One end of the fixed base 61 is provided with a second adjusting structure 66. The second adjusting structure 66 is a turbine screw jack. One end of the turbine screw jack is connected to the fixed base 61, and the other end is connected to the rotating device 64. Through the screw drive of the turbine screw jack, the third sawing machine 65 can be driven to move along the direction of the linear rail 62 on the fixed base 61. The cutting mechanism 6 further includes a third adjusting structure 67 installed at the bottom of the third sawing machine 65. The third adjusting structure 67 includes a trapezoidal screw rod 671 and a handle 672. One end of the trapezoidal screw rod 671 is rotatably connected to the rotating device 64, and the other end is rotatably connected to the bottom of the third sawing machine 65.

[0072] Specifically, by rotating the handle 672 to drive the trapezoidal screw rod 671 to rotate, the third sawing machine 65 can be driven to rotate around the rotating device 64. At the same time, by the second adjusting structure 66, the third sawing machine 65 is pushed to move along the direction of the linear rail 62, so that the positional relationship between the cutting opening in the third sawing machine 65 and the profiled steel can be changed, facilitating the cutting of the profiled steel.

[0073] Further, in one embodiment, the automatic section steel forming production line, wherein the material transfer and preparation mechanism 7 includes a material transfer and preparation support 71, one end of the material transfer and preparation support 71 is set as a material transfer area 711, and the other end is set as a material preparation area 712. A guide rail 72 is provided on the material transfer and preparation support 71, and a matching material transfer trolley 73 is installed on the guide rail 72. A second lifting device 74 is installed in the material transfer trolley 73. A material transfer inductor 75 is installed at one end of the material transfer trolley 73 near the material transfer area 711, and a material preparation inductor 76 is installed at one end of the material transfer trolley 73 near the material preparation area 712. A material transfer motor 77 for driving the material transfer trolley 73 to move on the guide rail 72 is also installed on the material transfer and preparation support 71. A material transfer roller 78 is also installed on the material transfer area 711. An auxiliary material supporting device 79 is also installed on one side of the material transfer and preparation support 71.

[0074] Specifically, the auxiliary material supporting device 79 is used to prevent the section steel from slipping due to unstable center of gravity after the cutting mechanism 6 cuts the section steel, and the auxiliary material supporting device 79 is used to assist in supporting the material. Further, in this embodiment, three guide rails 72 are arranged in parallel on the material transfer and preparation support 71, and corresponding matching material transfer trolleys 73 are installed on each guide rail 72. The second lifting device 74 is installed in the material transfer trolley 73. After rising, it drags the section steel to the material preparation area 712. The three material transfer trolleys 73 can effectively and stably support the section steel to prevent unstable center of gravity. The material transfer inductor 75 is installed at one end of the material transfer trolley 73 near the material transfer area 711, which is used to sense the position of the section steel. Only when the material transfer inductors 75 on all three material transfer trolleys 73 sense the section steel, the second lifting device 74 is controlled to rise and the material transfer trolley 73 is controlled to move, thus ensuring the safety of material transfer. The material preparation inductor 76 is installed at one end of the material transfer trolley 73 near the material preparation area 712, which is used to sense the distance between the material transfer trolley 73 and the positioning point of the material preparation area 712. After the material transfer trolley 73 reaches the sensing position, it is controlled to stop, and the second lifting device 74 is retracted, so as to regularize the material preparation.

[0075] During operation, after the cutting mechanism 6 cuts the steel section, a forward rotation signal is given to the material transfer motor 77. The three material transfer trolleys 73 are driven by a chain to rotate forward to search for the position of the steel section. When the material transfer inductor 75 senses a signal, the three material transfer trolleys 73 reach directly above the steel section. The second lifting devices 74 of the three material transfer trolleys 73 rise to lift the steel section away from the material transfer area 711 and move it to the stock preparation area 712. When the stock preparation inductors 76 on the three material transfer trolleys 73 sense that they have walked in place, a stop rotation signal is given to the material transfer motor 77. The second lifting devices 74 of the three material transfer trolleys 73 fall to place the steel section on the stock preparation area 712. The material transfer motor 77 rotates backward, and the three material transfer trolleys 73 return to the starting position to enter the next action process.

[0076] Furthermore, in one embodiment, for the automatic steel section forming production line, the welding mechanism 8 includes a gantry bracket 81, a positioner 82 installed below the gantry bracket 81, and a second automatic welding robot 83 installed on the gantry bracket 81.

[0077] Specifically, the gantry bracket 81 provides an installation position for the second automatic welding robot 83. The second automatic welding robot 83 can perform automatic welding. The positioner 82 is provided with a clamping device that can clamp the steel section and rotate it 180 degrees in the vertical direction. The second automatic welding robot 83 welds the end plates of the steel section to both ends of the steel section.

[0078] During operation, the worker uses a mold to fix the end plates of the steel section to both ends of the steel section, and then moves the steel section from the stock preparation area 712 to the positioner 82. The clamping device on the positioner 82 clamps the steel section on the positioner 82. Then, the second automatic welding robot 83 starts to weld the upper side of the end plate of the steel section. After welding, the positioner 82 rotates 180 degrees upward in the vertical direction to turn the lower side of the steel section into the upper side, and the second automatic welding robot 83 starts to weld. After welding is completed, the clamping device on the positioner 82 is loosened, and the steel section falls onto the second horizontal feeding device 91.

[0079] Furthermore, in one embodiment, for the automatic steel section forming production line, the storage mechanism 9 includes a second horizontal feeding device 91 and a storage rack 92 installed on one side of the second horizontal feeding device 91.

[0080] Specifically, the second horizontal feeding device 91 horizontally transports the steel section to the storage rack 92 for storage through a chain, that is, after the welding mechanism 8 finishes welding the steel section, the clamping device on the positioner 82 is loosened, and the steel section falls onto the second horizontal feeding device 91. The second horizontal feeding device 91 starts to work and transports the steel section to the storage rack 92 through a chain.
