Description

Technical Field

[0001] The invention relates to the technical field of steel mesh processing, and in particular to a processing line for steel mesh and steel cages. Background Art

[0002] Steel mesh and steel cages are widely used in building materials such as ALC panels (autoclaved lightweight concrete panels), primarily serving as the structural framework. Because steel chisels are used to hoist the mesh or cage into the mold during pouring, these mesh and cages require slots on both sides.

[0003] In the prior art, plastic clips are typically used to secure the steel mesh to both sides. These clips are equipped with holes for inserting steel bars. These clips can also serve as connectors to combine the steel mesh into a steel cage. The strength of these plastic clips is significantly lower than that of steel bars, which impacts the structural strength of the ALC board. Furthermore, assembling these clips can affect overall production efficiency. Therefore, the applicant proposes to directly bend the steel bars of the steel mesh itself, using these bent sections to assemble the steel cage. Furthermore, holes for inserting steel bars can be machined into these bent sections to improve the structural strength of the ALC board and thus enhance production efficiency.

DETAILED DESCRIPTION

[0079] In order to enable ordinary technicians in this field to more clearly understand the objectives, technical solutions and advantages of the present invention, the present invention is further explained below with reference to the accompanying drawings and embodiments, but the present invention is not limited to the following embodiments.

[0080] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", "front end", "rear end", "two ends", "one end", "the other end", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they cannot be understood as limiting the present invention.

[0081] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0082] like Figure 1As shown, this embodiment provides a processing line for steel mesh and steel cage, including a wire feeding device for conveying longitudinal and transverse steel bars, a welding device for welding the longitudinal and transverse steel bars into steel mesh, a bending device for bending the bending section reserved for the transverse steel bars, a cutting device for cutting the steel mesh, a pushing device for feeding the cut steel mesh backward, and a closing device for closing two steel meshes to form a steel cage. The wire feeding device includes a longitudinal wire feeding device and a transverse wire feeding device, both of which can adopt existing technologies. For example, the transverse wire feeding device can feed transverse steel bars of two lengths, wherein the transverse steel bars of longer length extend beyond the two sides of the steel mesh to form a bending section for bending. The welding device, cutting device, pushing device and closing device can all adopt existing technologies. For example, the welding device can adopt an automatic mesh welding machine.

[0083] like Figure 4 As shown, the bending device includes:

[0084] The first bending station, such as Figure 5 As shown, there is at least one steel bar bending mechanism provided on the first frame, which is used to bend the steel bars to be bent on both sides of the steel mesh to form vertical bending sections; generally, there are two steel bar bending mechanisms;

[0085] The second bending station, such as Figure 6 As shown, the machine comprises at least one steel bar stamping mechanism, at least one bending mechanism, and a workbench 113 for supporting the steel mesh, mounted on a second frame. A liftable pressure bar 114 is positioned above the workbench to compress the steel mesh during the stamping and bending processes. The pressure bar is driven by a driver and, in conjunction with a guide component, can be vertically lifted. The steel bar stamping mechanism is used to stamp the vertically bent section to form a bent portion 202.

[0086] Generally, there are two steel bar stamping mechanisms and two bending forming mechanisms, and the stamping directions (or arrangement directions) of the two steel bar stamping mechanisms are opposite, and the directions of the stamped bending parts are opposite, such as Figure 21 As shown, after the two steel mesh sheets are folded up and down and welded into a steel mesh cage, the two bent portions 202 are arranged opposite to each other to form a steel drill insertion hole 203.

[0087] The second lifting beam and the sliding pair of the bending and forming mechanism can be installed on the second frame in a liftable manner. The height adjustment screw rod 112 is used in conjunction with the nut to control the lifting of the second lifting beam. Obviously, the lifting of the second lifting beam can also be controlled by components such as cylinders.

[0088] In order to adjust the distance between the first bending station and the second bending station and adapt to the steel mesh with different transverse steel bar spacing, in this embodiment, at least one of the first frame and the second frame is slidably installed on the base and can slide longitudinally on the base under the action of a driving member. The driving member is recommended to adopt a structure of a spacing adjustment screw rod 526 and a nut. Generally, the first bending station and the second bending station are both slidably installed on the base and are respectively connected to the spacing adjustment screw rod 526 through nuts. The thread directions of the screw rod parts connected to the nuts of the first bending station and the second bending station are opposite.

[0089] When some ALC panels are cast, single steel mesh is used for structural reinforcement, such as Figure 20 As shown, it is necessary to process steel bar insertion holes 203 on both sides of the single mesh, and the bending and forming mechanism is mainly used for bending and forming the steel bar insertion holes of this type of steel mesh.

[0090] like Figure 2 As shown, the steel bar socket bending and forming mechanism includes a second lifting beam 100 and two bending assemblies 101. The second lifting beam 100 primarily serves as a mounting base for the bending assemblies 101. Obviously, the two bending assemblies 101 should be installed on either side of the steel mesh 200, located on the left and right sides of the second lifting beam 100. Each bending assembly 101 includes a sliding seat 105, a movable pressing die 106, and a movable backing die 111 slidably disposed on the sliding seat 105. The sliding seats 105 of both bending assemblies 101 are slidably engaged with the second lifting beam 100 via a sliding pair and are each driven by a driving member. The sliding seat 105 slides in the transverse direction of the steel mesh 200. A path for the steel mesh 200 is formed between the sliding seats 105 of the two bending assemblies 101. The driving member allows the sliding seats 105 of the two bending assemblies 101 to move closer together or further apart, accommodating steel meshes 200 of varying widths.

[0091] like Figure 2 、 Figure 3As shown, in this embodiment, a transverse through hole is provided on the sliding seat 105, and the movable backing mold 111 is movably mounted in the transverse through hole. A driving member is provided on the outer wall of the sliding seat 105, and the movable backing mold 111 can slide in the transverse direction of the steel mesh 200 under the action of the driving member. A guide block 107 with a longitudinal guide groove and a longitudinal through hole is provided in the sliding seat 105, and the movable pressing mold 106 is movably mounted in the longitudinal guide groove. One end of the movable pressing mold 106 is connected to the driving member, and the other end faces the side where the movable backing mold 111 is located. The movable pressing mold 106 can slide in the longitudinal direction of the steel mesh 200 under the action of the driving member. The vertical bending section 201 of the steel mesh 200 can be allowed to enter between the guide block 107 and the movable support mold 111. When the movable pressing die 106 is pushed out, the vertical bending section 201 of the steel mesh 200 is pressed against the movable support mold 111, so that the bending section 201 bends along the forming surface of the movable support mold 111 to form a steel drill socket.

[0092] Specifically, if Figure 4 As shown, the forming surface of the movable backing mold 111 includes a primary bending forming surface 103 and a secondary bending forming surface 104, and the primary bending forming surface 103 is relatively closer to the transverse through hole;

[0093] The lower side of one end of the movable pressing die 106 facing the movable backing die 111 is provided with a primary molding port 109 corresponding to the primary bending molding surface 103 and a secondary molding port 110 corresponding to the secondary bending molding surface 104. The primary molding port 109 is located above the secondary molding port 110.

[0094] The bending section 201 is first pressed by the primary die pressing port 109 onto the primary bending forming surface 103 for bending, and then the driving member drives the movable backing die 111 to retract, so that the secondary die pressing port 110 is opposite to the movable die 106. Then, the bending section 201 that has been bent once is pressed by the secondary die pressing port 110 onto the secondary bending forming surface 104 for bending, forming a steel drill socket, and the plane where the steel drill socket is located is basically perpendicular to the transverse steel bar.

[0095] A spring rod 108 is provided in the longitudinal through hole of the guide block 107 . The spring rod 108 is connected to the movable pressing die 106 and can be longitudinally extended. When the movable pressing die 106 moves toward the movable supporting die 111 , the spring rod 108 pre-presses the bending section 201 onto the movable supporting die 111 .

[0096] The sliding seat 105 and the guide block 107 are provided with a receiving groove 102 for receiving the longitudinal steel bars, so as to prevent the outermost longitudinal steel bars from being blocked, thereby allowing the bending section 201 to enter between the guide block 107 and the movable backing 111.

[0097] In this embodiment, it is recommended to use the cylinder 115 as the driving member of the sliding seat 105.

[0098] When the bending operation is not performed, the distance between the two bending components 101 is relatively far. When the sections to be bent 201 on both sides of the steel mesh 200 reach the predetermined position, the distance between the two bending components 101 becomes closer, and the vertical bending section 201 of the steel mesh 200 enters between the guide block 107 and the movable support mold 111. The primary bending forming surface 103 of the movable support mold 111 faces the primary molding port 109 of the movable pressure die 106. The movable pressure die 106 is pushed out to bend the upper end of the bending section 201. Then the movable support mold 111 slides to make the secondary bending forming surface 104 face the secondary molding port 110 of the movable pressure die 106. The movable pressure die 106 is pushed out again, and the bending section 201 is bent again on the secondary bending forming surface 104 to form a steel bar socket. During the two bending processes, the spring rod 108 maintains the top pressure on the bending section 201 to reduce the deviation of the bending section 201. Afterwards, the movable pressing die 106 and the movable backing die 111 are reset, and the two bending components 101 are separated again to detach from the steel mesh 200 and wait for the next operation.

[0099] like Figure 5 、 Figure 6 as well as Figures 10 to 12 As shown, the bending device includes a first frame 500 and two bending stations, each bending station has a steel bar pre-stressing mechanism, a steel bar bending mechanism, etc., wherein the steel bar bending mechanism has a working platform 501, a clamping mechanism and a jacking mechanism, etc. The working platform 501 is fixed on the first frame 500, and the working platform 501 is used to place the steel mesh 200 to be bent.

[0100] like Figure 14 As shown, the steel bar prestressing mechanism includes a prestressing plate 519 and a prestressing drive mechanism 520, wherein the prestressing plate 519 is located above the working platform 501. The lower end surface of the prestressing plate 519 is formed with a guide groove adapted for the transverse steel bars. The upper end of the prestressing plate 519 is connected to the operating end of the prestressing drive mechanism 520 via a connector, and the prestressing drive mechanism 520 is mounted and fixed on the first frame 500. In this embodiment, the prestressing drive mechanism 520 can drive the prestressing plate 519 to move up and down. When the prestressing plate 519 moves downward to press the transverse steel bars to be bent on the working platform 501, the guide groove on the lower end surface of the prestressing plate 519 positions the transverse steel bars to be bent on the steel mesh 200 at a designated position on the working platform 501.

[0101] The clamping mechanism includes a bending upper mold fixing plate 511 and a clamping drive mechanism 512, wherein the bending upper mold fixing plate 511 is located above the pre-stressing plate 519, and the lower edge of the bending upper mold fixing plate 511 is provided with a bending portion corresponding to the pre-stressing plate 519, so that the bending upper mold fixing plate 511 can further clamp the transverse steel bars clamped and positioned by the pre-stressing plate 519; the bending upper mold fixing plate 511 is connected to the action end of the clamping drive mechanism 512, and the clamping drive mechanism 512 is fixed on the first frame 500. The clamping drive mechanism 512 can drive the bending upper mold fixing plate 511 to move up and down, and the bending upper mold fixing plate 511 moves downward to clamp the middle section of the transverse steel bars to be bent on the working platform 501.

[0102] like Figure 5 、 Figure 6 as well as Figures 10 to 12 As shown, the jacking mechanism is located below the working platform 501 and has a jacking slide 502, a jacking arm 503 and a bending angle adjustment mechanism.

[0103] There are two lifting slides 502, each corresponding to the bending sections 201 at both ends of the transverse steel bar to be bent. The lifting slides 502 are arranged vertically and are equipped with vertical slide rails I, which are equipped with sliders I. Slider I is connected to the first frame 500 via a slider base, so that the lifting slides 502 can only move vertically under the action of sliders I and vertical slide rails I.

[0104] The lower ends of the two lifting slides 502 are commonly connected to the lifting arm, and a lifting drive mechanism 505 is connected to the lower middle part of the lifting arm. The lifting drive mechanism 505 can drive the two lifting slides 502 to move up and down through the lifting arm.

[0105] The jacking arm 503 is installed in the upper part of the jacking slide 502. The lower end of the jacking arm 503 can be rotatably connected to the middle part of the jacking slide 502 via the rotating shaft 525. The upper end of the jacking arm 503 can be rotatably connected to the V-groove roller 504 via the rotating shaft 525. The upper groove of the V-groove roller 504 is adapted to the steel bar. The V-groove roller 504 is used to contact the steel bar when the jacking mechanism moves upward.

[0106] A bending angle adjustment mechanism is provided in the middle position of the two lifting slides 502. The bending angle adjustment mechanism is connected to the two lifting arms 503 on the two lifting slides 502, and is used to adjust the angle at which the lifting arm 503 rotates around its lower end rotating shaft 525 during the upward movement of the lifting slide 502, thereby adjusting the angle at which the lifting arm 503 and the V-groove roller 504 bend the steel bars.

[0107] The bending angle adjustment mechanism includes a connecting rod seat 506 and a vertical position adjustment mechanism, wherein the connecting rod seat 506 is connected to two connecting rods 507 corresponding to the two lifting arms 503, one end of the connecting rod 507 is connected to the connecting rod seat 506 via a pin shaft, and the other end of the connecting rod 507 is connected to the middle part of the corresponding lifting arm 503 via a pin shaft; the connecting rod seat 506 can be adjusted to a vertical position by the vertical position adjustment mechanism and is fixed on the lower end surface of the working platform 501, and the vertical position of the connecting rod seat 506 is adjusted to achieve the angle of rotation of the lifting arm 503 around its lower end rotating shaft 525 during the upward movement of the lifting slide 502.

[0108] The vertical position adjustment mechanism includes a guide rod 508, a fixed seat 509 and a bushing 510, wherein the guide rod 508 is arranged vertically, and the connecting rod seat 506 is installed on the guide rod 508 through the bushing 510. The upper end of the guide rod 508 is provided with an external thread, and the fixed seat 509 is fixed to the lower end surface of the working platform 501. The fixed seat 509 is provided with a screw hole that is adapted to the external thread on the guide rod 508. The guide rod 508 is threadedly connected to the fixed seat 509. The upper and lower positions of the guide rod 508 are adjusted by rotating the guide rod 508 to cooperate with the screw holes on the fixed seat 509, thereby adjusting the upper and lower positions of the connecting rod seat 506 on the guide rod 508.

[0109] In this embodiment, the bushing 510 is fixed on the guide rod 508, and a limiting ring is formed on the upper end of the bushing 510. The connecting rod seat 506 is sleeved on the bushing 510, and the limiting ring on the upper end of the bushing 510 limits the connecting rod seat 506 from moving upward.

[0110] In this embodiment, a plurality of vertically arranged guide rods 521 are mounted on the connecting rod base 506. A guide member 522 is mounted on a lifting arm 524 below the connecting rod base 506, corresponding to the guide rods 521. The guide rods 521 are provided with guide holes adapted to fit the guide rods 521. The upper ends of the guide rods 521 are connected to the connecting rod base 506, while the lower ends of the guide rods 521 extend downwardly through the guide holes in the guide member 522. In this embodiment, a spring is mounted on the guide rod 521. The upper end of the spring abuts against a retaining ring on the upper portion of the guide rod 521, while the lower end of the spring is supported on the guide member 522.

[0111] In this embodiment, the connecting rod seat 506 is sleeved on the bushing 510, and the two can rotate relative to each other. Under the action of the guide rod 521 and the spring, the connecting rod seat 506 is pressed from bottom to top on the limit ring at the upper end of the bushing 510.

[0112] In this embodiment, the vertical position of the bushing 510 on the guide rod 508 is adjusted by rotating the guide rod 508 and utilizing the threaded connection between the guide rod 508 and the fixed seat 509, thereby adjusting the upper and lower positions of the connecting rod seat 506, and finally achieving the inclination adjustment of the lifting arm 503.

[0113] like Figure 7 、 Figure 9As shown, the steel bar stamping mechanism has a first lifting beam 513 and a stamping groove 515, wherein sliders II are installed at both ends of the first lifting beam 513, and the sliders II are installed on the first frame 500 via vertical slide rails II. The middle part of the first lifting beam 513 is connected to the action end of the stamping lifting mechanism 514, and the stamping lifting mechanism 514 is fixed on the first frame 500. The stamping lifting mechanism 514 can drive the first lifting beam 513 to move up and down.

[0114] The steel bar stamping mechanism is equipped with a stamping slot 515, corresponding to each of the two bent sections 201 at each end of the transverse steel bar. These two stamping slots 515 are mounted on the first lifting beam 513 for horizontal movement via a horizontal transverse mechanism. In this example, the horizontal transverse mechanism comprises a transverse rail mounted on the first lifting beam 513, which is connected to the stamping slots 515 via a transverse slider and a connecting plate. A transverse drive mechanism is located between the two stamping slots 515. This transverse drive mechanism is fixed to the first lifting beam 513, with its actuating end connected to the connecting plate. This mechanism can drive the stamping slots 515 to move horizontally along the transverse rail via the connecting plate.

[0115] A stamping die 516 is fixed to one end of the wall of the stamping slot 515, and a stamping punch 517 is installed at the other end of the stamping slot 515. The position of the stamping punch 517 corresponds to the position of the stamping die 516. The stamping punch 517 is connected to the operating end of the stamping drive mechanism 518, and the stamping drive mechanism 518 is fixedly connected to the stamping slot 515. The stamping drive mechanism 518 can drive the stamping punch 517 to move toward or away from the corresponding stamping die 516.

[0116] The steel mesh 200 to be bent enters the bending device longitudinally and is placed on the working platform 501 of the first bending station;

[0117] After the transverse steel bar to be bent is moved to the corresponding position on the working platform 501, the steel bar pre-pressing mechanism is activated to press the transverse steel bar to be bent through the pre-pressing plate 519, so that the transverse steel bar is positioned at the specified position;

[0118] The pressing mechanism moves the upper bending die plate 511 downward to press the transverse steel bars at a designated position on the lower working platform 501. The upper bending die plate 511 presses the middle section of the transverse steel bars, and the unpressed sections at both ends of the transverse steel bars are the subsequent bending sections 201.

[0119] The jacking drive mechanism 505 drives the jacking slide 502 to move upward, and the jacking slide 502 drives the jacking arm 503 to move upward. Since the middle part of the jacking arm 503 is connected to the connecting rod seat 506 via the connecting rod 507, the jacking arm 503 gradually rotates around the lower end rotation axis 525 during the upward movement of the jacking arm 503, and the upper end of the jacking arm 503 gradually tilts toward the connecting rod seat 506, and the tilt angle gradually increases;

[0120] During the upward movement of the jacking arm 503, the V-groove roller 504 at its upper end contacts the bending section 201 of the transverse steel bar to bend the bending section 201, and as the tilt angle of the jacking arm 503 increases, the bending angle of the bending section 201 gradually increases;

[0121] After the jacking drive mechanism 505 drives the jacking slide 502 to move up to the specified position, it drives the jacking slide 502 to move downward, and the jacking arm 503 gradually returns to its original position;

[0122] To avoid interference with subsequent stamping operations, after the jacking mechanism is reset, the clamping mechanism is activated to drive the bending upper die fixing plate 511 to move upwards.

[0123] The bending section 201 is bent to a vertical state, forming a substantially 90° angle with the plane where the steel mesh 200 is located;

[0124] The steel mesh continues to move and enters the workbench of the second bending station. At this time, if a single steel mesh needs to be processed, it enters the steel drill socket bending and forming mechanism, and the two bending components bend the bending section; if the steel mesh required by the steel mesh cage needs to be processed, the height of the steel bar stamping mechanism is adjusted so that the steel mesh enters the steel bar stamping mechanism. After the transverse steel bar reaches the predetermined position, the pressure bar descends to press the transverse steel bar. The structure of the pressure bar can refer to the bending upper mold fixing plate 511. The steel bar stamping mechanism is activated so that the bending sections 201 at both ends of the transverse steel bar on the working platform 501 are located in the stamping groove 515.

[0125] The stamping drive mechanism 518 is activated to drive the stamping punch 517 to move toward the stamping die 516 , thereby stamping and forming a bent portion on the bending section 201 between the stamping punch 517 and the stamping die 516 .

[0126] The wire feeding device is provided with a steel bar straightening device for straightening the steel bars. Generally, the steel bars are rolled down and replaced for straightening. The steel bar straightening device includes a frame 1 and a straightening mechanism 3 installed on the top of the frame 1. The number of straightening mechanisms 3 is determined according to the application scenario. In this embodiment, two groups of straightening mechanisms 3 are arranged side by side on the frame 1.

[0127] like Figure 15 、 Figure 17 、 Figure 18 As shown, the straightening mechanism 3 includes several straightening cylinders 32 arranged side by side. The number of straightening cylinders 32 is determined according to the application scenario. In this embodiment, the straightening mechanism 3 is provided with four horizontal straightening cylinders 32, which are arranged in parallel with each other at a certain distance. The two ends of the straightening cylinders 32 are supported by bearing seats 35. Each straightening cylinder 32 is connected to the driving mechanism and realizes circumferential rotation under the drive of the driving mechanism. Specifically, as shown in FIG. Figure 4As shown, the drive mechanism includes a straightening motor 5, a plurality of transmission gears 37, and a driving gear 313. The transmission gears 37 are mounted within a housing 34 and mesh with each other directly or through intermediate gears. When directly meshed, the two straightening cylinders 32 rotate in opposite directions, while when meshed through intermediate gears, they rotate in the same direction. These transmission gears 37 are fixed one-to-one to the outer wall of the straightening cylinder 32. The driving gear 313 is fixed to the output shaft of the straightening motor 5 and meshes with one of the transmission gears 37. When the driving gear 313 rotates, the remaining transmission gears 37 also rotate, thereby driving the corresponding straightening cylinder 32 to rotate.

[0128] In this embodiment, Figure 15 、 Figure 16 、 Figure 18 as well as Figure 19 As shown, each straightening cylinder 32 is formed with a set of radial threaded through-holes 310. These threaded through-holes 310 are arranged at a predetermined spacing along the length of the straightening cylinder 32. The spacing between the threaded through-holes 310 can be the same or different. Obviously, the threaded through-holes 310 intersect with the inner bore of the straightening cylinder 32. The straightening cylinder 32 is also formed with a plurality of auxiliary holes 36. The auxiliary holes 36 are staggered with the threaded through-holes 310. As one staggered arrangement, the auxiliary holes 36 and the threaded through-holes 310 are spaced apart from each other.

[0129] like Figure 19 As shown, a straightening block 38 is mounted within the threaded through hole 310. Both ends of the straightening block 38 are secured by screws 311 screwed into the threaded through hole 310. A straightening through hole 39 is defined in the center of the straightening block 38. This straightening through hole 39 is coaxial with the straightening cylinder 32, and the diameter of the straightening through hole 39 matches the outer diameter of the rebar. When the rebar is inserted into the straightening cylinder 32, a tool such as a screwdriver can be inserted into the auxiliary hole 36 to apply force to the head of the rebar, forcing it into the straightening through hole 39 of the straightening block 38. Furthermore, the auxiliary hole 36 also serves to dissipate heat and remove chips during rebar straightening. The straightening block 38 is square in shape, and the threaded through hole 310 is adapted to fit within the straightening block 38. The inner walls of the threaded through hole 310 are provided with internal threads 312 that match the screws 311. The axes of the threaded through holes 310 are perpendicular to the axis of the straightening cylinder 32 . The threaded through holes 310 may be staggered at a certain angle, or the axes of all the threaded through holes 310 may be on the same plane.

[0130] like Figure 16 As shown, the front end of the straightening mechanism 3 is provided with a plurality of cone sleeves 31 for guiding the steel bars. The cone sleeves 31 correspond to the straightening cylinders 32 one by one and are coaxial. The rear end of the straightening mechanism 3 is provided with a traction mechanism corresponding to the straightening mechanism 3. The traction mechanism includes a plurality of pairs of traction wheels, a traction motor 2, a rotating shaft 6, a swing frame 9 and a cylinder 7. Figure 1 、 Figure 3As shown, the rotating shaft 6 is driven by the traction motor 2. Each pair of traction wheels corresponds to a straightening cylinder 32. The outer circumferential walls of the driving wheel 13 and the pressure wheel 10 of each pair of traction wheels are provided with grooves. When the pressure wheel 10 presses against the driving wheel 13, the gap formed by the grooves between the two wheels serves as a passage for the steel bars. A guide tube 33 is provided between the outlet of the straightening cylinder 32 and the driving wheel 13 of the traction mechanism.

[0131] In the traction wheel, the driving wheel 13 is fixed to the rotating shaft 6, the pressure wheel 10 is rotatably mounted on the swing frame 9, the cylinder 7 is mounted on the gantry 12 via the bracket 8, and the gantry 12 is mounted on the frame 1. One end of the swing frame 9 is hinged to the frame 1 via the hinge shaft 11, and the other end is cantilevered and hinged to the push rod of the cylinder 7. When the push rod of the cylinder 7 is actuated, the pressure wheel 10 presses against the driving wheel 13 or moves away from the driving wheel 13. The hinge shaft 11 is mounted on the gantry 12. Generally, each swing frame 9 shares the hinge shaft 11, and the other end of each swing frame 9 is connected to a cylinder 7. A compressed air tank 4 is mounted on the gantry 12, which is connected to the cylinder 7 to supply air thereto.

[0132] During operation, the steel bar passes through the cone sleeve 31 and then into the straightening cylinder 32. After passing through the straightening inner holes of each straightening block 38, the steel bar comes out from the outlet of the straightening cylinder 32 and passes through the guide tube 33 to reach the groove of the driving wheel 13. The push rod of the cylinder 7 is pushed out, driving the swing frame 9 to swing down so that the pressure wheel 10 presses the steel bar against the driving wheel 13. As the traction motor 2 rotates, the steel bar is continuously pulled forward. During the movement, the straightening block 38 rotates with the straightening cylinder 32, and the straightening through hole 39 of the straightening cylinder 32 applies force to the bent part of the steel bar to straighten the bent steel bar.

[0133] The working principle of the steel bar straightening device to straighten the bent steel bars is:

[0134] The push rod of the cylinder 7 is pushed out, and the pressure wheel 10 of the traction mechanism is swung down, clamping the steel bar together with the driving wheel 13. As the traction motor 2 drives the driving wheel 13 to rotate, the pulled steel bar continuously enters the straightening cylinder 32;

[0135] The straightening motor 5 rotates with the driving gear 313, causing the straightening cylinder 32 to rotate circumferentially, and applying pressure to the bent portion of the traction steel bar through the straightening through holes 39 in the plurality of straightening blocks 38 to achieve straightening of the steel bar.

[0136] After the steel bars are unwound, they are straightened by the straightening device. Multiple longitudinal steel bars are continuously advanced, and the transverse steel bars are sent to the longitudinal steel bars at a certain interval, and then welded into a mesh. The bent sections are bent on the bending device. If a single mesh is used, it is directly bent into a steel drill socket by the bending forming mechanism. If a steel mesh cage is required, the steel bar stamping mechanism will process the bent part. When closing, the bent sections of the two steel meshes are welded to form a mesh cage, and the bent parts of the two bent sections are spliced ​​together to form a steel drill socket.

[0137] The above are only specific embodiments of the present application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
