Description

Technical Field

[0001] This invention relates to the field of steel mesh processing technology, and in particular to a bidirectional automatic bending device for both ends of a steel mesh and its processing method. Background Technology

[0002] In construction engineering, it is often necessary to process steel bars into various skeleton forms to meet project requirements. The traditional processing method mainly involves manually operating a single machine to bend the steel bars into stirrups and folded-edge steel bars, then manually placing the stirrups and folded-edge steel bars on a formwork, inserting the longitudinal steel bars, arranging them in position, and then tying them in place. With the advent of mesh bending machines, the processing method of bending precast steel mesh to form folded-edge steel mesh and rectangular steel cages has been widely used.

[0003] When using a mesh bending machine to bend steel mesh, manual handling is required for feeding and collecting finished products. During the bending process, the position of the steel cage is prone to shifting, requiring manual assistance. However, due to the large surface area and volume of the steel cage, it is difficult to handle, which reduces processing efficiency. Furthermore, the spacing between the steel bars inside various steel meshes is different, and the horizontal and vertical bars can easily prevent the bending mechanism from passing through the gaps between the steel bars to process them, making it difficult to quickly process complex-shaped steel skeletons.

[0004] Therefore, it is necessary to provide a new bidirectional automatic bending device for both ends of a steel mesh and its processing method to solve the above-mentioned technical problems. Summary of the Invention

[0005] The technical problem solved by this invention is to provide a device and method for automatically bending both ends of a steel mesh to accelerate construction efficiency and process complex-shaped steel reinforcement cages according to requirements.

[0006] To solve the above-mentioned technical problems, the present invention provides a bidirectional automatic bending device for steel mesh at both ends, comprising: a feeding rack and a finished product collection rack, wherein two forward bending machines and two reverse bending machines are arranged between the feeding rack and the finished product collection rack. The forward bending machine includes a first fixed frame, the side wall of which is equipped with multiple first hydraulic rods that drive the forward bending machine head to rotate and the fixed beam to move up and down. The top of the first fixed frame is rotatably connected to a forward bending machine head for bending and reinforcing the steel mesh. The top of the first fixed frame is rotatably connected to a lower support beam for raising and supporting the steel mesh. An I-shaped fixed beam is slidably connected inside the first fixed frame, and multiple sliding sleeves are slidably connected to the surface of the fixed beam. Fasteners for fixing the steel mesh are fixedly connected to the surface of the sliding sleeves. The reverse bending machine includes a second fixed frame and a third fixed frame. The sidewall of the second fixed frame is slidably connected to support the upper fixed beam of the reinforcing mesh, and the interior of the third fixed frame is rotatably connected to a reverse bending head for bending the reinforcing mesh. The sidewalls of both the second and third fixed frames are equipped with second hydraulic rods that drive the upper fixed beam up and down and the reverse bending head to rotate. The outer sides of both the loading rack and the finished product collection rack are equipped with mesh moving carts. Each mesh moving cart includes a frame, and the surface of the frame is slidably connected to a crossbeam for moving the reinforcing mesh left and right. The sidewall of the crossbeam is equipped with a column for moving the reinforcing mesh back and forth, and the bottom end of the column is rotatably connected to multiple clamps for clamping the reinforcing mesh. The bottom ends of both the forward bending machine and the reverse bending machine are equipped with translation mechanisms to change their positions, and the sidewalls of both the mesh moving cart and the translation mechanism are equipped with moving mechanisms.

[0007] Preferably, the moving mechanism includes a gear, a rack, a third roller, and a motor, with the gear mounted on one side of the motor and meshing with the rack.

[0008] Preferably, the moving mechanism is installed between the frame and the crossbeam and between the crossbeam and the column. The rack is installed on the side wall of both the frame and the crossbeam, and the motor and the third roller are respectively installed on the side wall of the crossbeam. The third roller is slidably connected to the side wall of the frame.

[0009] Preferably, the mesh moving vehicle further includes a fixed plate, on which the motor is installed on both ends of the fixed plate, and a first roller is installed on the side wall of the fixed plate, the first roller being slidably connected to the crossbeam; the rack is installed on the side wall of the column, and the rack meshes with the gear on one side of the fixed plate.

[0010] Preferably, a limiting mechanism is installed between the column and the fixing plate. The limiting mechanism includes a guide rail, which is fixed to the side wall of the column. A slide rod is engaged and slidably connected inside the guide rail, and the slide rod is fixed to the side wall of the fixing plate. A fourth hydraulic rod for limiting the column is installed on the side wall of the fixing plate. A locking strip is installed on one side of the fourth hydraulic rod. The locking strip is slidably connected to the slide rod, and the locking strip engages with the rack on the side wall of the column.

[0011] Preferably, the mesh moving vehicle further includes a third hydraulic rod, and multiple third hydraulic rods are symmetrically installed at the bottom of each column. The bottom of each third hydraulic rod is fitted with a compression sleeve for closing the clamp. The compression sleeve is slidably connected to the side wall of the clamp, and a spring is installed at the top of the clamp for resetting it.

[0012] Preferably, the translation mechanism includes a base, a ground rail, and a moving mechanism. The base is installed at the bottom of both the forward bending machine and the reverse bending machine. The motor and the third roller are installed inside the base. The rack is installed inside the ground rail, and the third roller is slidably connected to the ground rail.

[0013] Preferably, a processing method for automatically bending both ends of a steel mesh in both directions specifically includes the following steps:

[0014] Step 1: First, the steel mesh to be processed is placed on the loading rack. Two sets of mesh moving trolleys grab and load the steel mesh along the longitudinal direction. The surface of the first fixed frame is rotatably connected to the lower support beam. The steel mesh moves on the surface of the lower support beam, which in turn drives the lower support beam to rotate, so that the steel mesh reaches the predetermined position. The translation mechanism drives the forward bending machine and the reverse bending machine to move. At the same time, the mesh moving trolley adjusts the position of the steel mesh so that the steel mesh is aligned with the forward bending machine and the reverse bending machine.

[0015] Step Two: Before reverse bending, the reinforcing mesh reaches the bending position, and the bending position of the reinforcing mesh is aligned with the upper fixed beam. The mesh moving vehicle grabs and fixes the reinforcing bars. The translation mechanism drives the forward bending machine to move, causing the fastener to be misaligned with the reinforcing bars. The first hydraulic rod is opened, and the first hydraulic rod pushes the fixed beam and the fastener upward, allowing the fastener to pass through the gap between the reinforcing bars. The translation mechanism is opened, and the fastener moves to align with the reinforcing bars. The first hydraulic rod retracts, causing the fastener to move downward. The fastener has a slot on its side wall, and the reinforcing bars enter the slot, allowing the fastener and the lower support beam to fix the reinforcing mesh, achieving reverse bending positioning, increasing the stability of the reinforcing mesh during processing, and preventing the reinforcing mesh from being misaligned. The second hydraulic rod on the side wall of the second fixed frame operates, driving the upper fixed beam to move, causing the upper fixed beam to press the bending position of the reinforcing mesh. The second hydraulic rod on the surface of the third fixed frame is opened, and the second hydraulic rod drives the reverse bending machine head to rotate downward, causing the reverse bending machine head to press the reinforcing mesh downward, bending the reinforcing mesh in the reverse direction.

[0016] Step 3: During forward bending, the mesh moving vehicle swings and adjusts the reinforcing mesh so that the bending position of the reinforcing mesh is aligned with the edge of the fastener; the mesh moving vehicle then grabs and fixes the reinforcing bar, and similarly, following Step 2, the fastener clamps and secures the reinforcing bar, fixing the reinforcing mesh. At the same time, the edge of the fastener presses against the bending position of the reinforcing mesh, and the first hydraulic rod is opened. The first hydraulic rod rotates on the side wall of the base, simultaneously driving the forward bending head to rotate upward and press the reinforcing mesh, bending the reinforcing mesh in the forward direction; the mesh moving vehicle is used to adjust the bending position of the mesh, and the above clamping and bending actions are repeated.

[0017] Step 4: The bent steel reinforcement cage is picked up and transported to the finished product collection rack by two sets of mesh moving vehicles along the machine frame.

[0018] Compared with related technologies, the automatic bidirectional bending device and processing method for steel mesh provided by the present invention have the following advantages:

[0019] This invention provides a bidirectional automatic bending device for both ends of a reinforcing mesh and its processing method. During processing, the mesh moving carriage adjusts the position of the reinforcing mesh to align it with either the forward bending machine or the reverse bending machine. Before reverse bending, the reinforcing mesh reaches the bending position, which is aligned with the upper fixed beam. The mesh moving carriage grips and fixes the reinforcing bars. The translation mechanism drives the forward bending machine to move, causing the fasteners to disengage from the reinforcing bars. The sliding sleeve is slidably connected to the fixed beam, and the fasteners can be adjusted according to the spacing between the reinforcing bars. The spacing between the components facilitates the misalignment of the fasteners and the reinforcing bars. Opening the first hydraulic rod pushes the fixing beam and the fasteners upwards, allowing the fasteners to pass through the gaps between the reinforcing bars. Opening the translation mechanism aligns the fasteners with the reinforcing bars. The first hydraulic rod retracts, causing the fasteners to move downwards. The fastener's sidewall has a slot, allowing the reinforcing bars to enter the slot, thus fixing the reinforcing mesh with the fastener and the lower support beam. This achieves reverse bending positioning, increasing the stability of the reinforcing mesh during processing and preventing misalignment. The second fixing frame's sidewall... The second hydraulic rod operates, driving the upper fixed beam to move, causing the upper fixed beam to press against the bent position of the reinforcing mesh. This opens the second hydraulic rod on the surface of the third fixed frame, causing the second hydraulic rod to rotate the reverse bending head downwards, pressing the reinforcing mesh downwards and bending it in the reverse direction. During forward bending, the mesh moving carriage swings to adjust the reinforcing mesh, aligning the bent position of the mesh with the edge of the fastener. The mesh moving carriage then grabs and fixes the reinforcing bars, and similarly, following the above process, the fasteners clamp the reinforcing bars, thus bending the reinforcing mesh... The reinforcing mesh is fixed in place, and the edges of the fasteners press against the bending points of the reinforcing mesh. The first hydraulic rod is then opened, and it rotates on the side wall of the base, simultaneously driving the forward bending head to rotate upward and press the reinforcing mesh, bending it in the forward direction. This allows for the rapid assembly of the required reinforcing mesh skeleton as needed. During the bending process, the mesh moving carriage can adjust the position of the reinforcing mesh, increasing the accuracy of the bending effect. Furthermore, the mesh moving carriage and the fasteners firmly fix the reinforcing mesh during the bending process, improving the quality of the processed reinforcing cage.

Figure 12 for Figure 11The diagram shows a bending schematic of the reinforcing mesh. The bidirectional automatic bending device for the reinforcing mesh includes: a feeding rack 4, a finished product collection rack 5, and two forward bending machines 1 and two reverse bending machines 2 arranged between the feeding rack 4 and the finished product collection rack 5. Each forward bending machine 1 includes a first fixed frame 11. Multiple first hydraulic rods 14 are installed on the side wall of the first fixed frame 11 to drive the forward bending machine head 13 to rotate and the fixed beam 16 to move up and down. The top of the first fixed frame 11 is rotatably connected to the forward bending machine head 13 for bending and reinforcing the reinforcing mesh 7. The top of the first fixed frame 11 is rotatably connected to a lower support beam 12 for raising and supporting the reinforcing mesh 7. The interior of the first fixed frame 11 is slidably connected to an I-shaped... A fixed beam 16 is provided, with multiple sliding sleeves 17 slidably connected to its surface, and fasteners 15 for fixing the reinforcing mesh 7 fixedly connected to the surface of each sliding sleeve 17. The reverse bending machine 2 includes a second fixed frame 21 and a third fixed frame 23. The side wall of the second fixed frame 21 is slidably connected to an upper fixed beam 24 supporting the reinforcing mesh 7, and the interior of the third fixed frame 23 is rotatably connected to a reverse bending head 25 for bending the reinforcing mesh 7. Second hydraulic rods 22 are installed on the side walls of both the second fixed frame 21 and the third fixed frame 23 to drive the upper fixed beam 24 up and down and the reverse bending head 25 to rotate. During reverse bending, the reinforcing mesh 7... The bending position of the reinforcing mesh 7 is aligned with the upper fixed beam 24; the mesh moving vehicle 3 grabs and fixes the reinforcing bars; the translation mechanism 6 drives the forward bending machine 1 to move, causing the fastener 15 to be misaligned with the reinforcing bars; the first hydraulic rod 14 is opened, pushing the fixed beam 16 and the fastener 15 upward, allowing the fastener to pass through the gap between the reinforcing bars; the translation mechanism 6 is opened again, causing the fastener 15 to move and align with the reinforcing bars; the first hydraulic rod 14 retracts, causing the fastener 15 to move downward; the fastener 15 has a slot on its side wall, and the reinforcing bars enter the slot, thus fixing the reinforcing mesh 7 with the fastener 15 and the lower support beam 12, achieving... Reverse bending positioning increases the stability of the steel mesh 7 during processing and prevents misalignment. The operation of the second hydraulic rod 22 on the side wall of the second fixing frame 21 drives the upper fixing beam 24 to move, causing the upper fixing beam 24 to press the bending position of the steel mesh 7. This opens the second hydraulic rod 22 on the surface of the third fixing frame 23, which in turn drives the reverse bending head 25 to rotate downwards, causing the reverse bending head 25 to press the steel mesh 7 downwards and bend it in the reverse direction. When bending in the forward direction, the mesh moving carriage 3 swings to adjust the steel mesh 7 so that the bending position of the steel mesh 7 is aligned with the edge of the fastener 15.The mesh moving vehicle 3 then grips and fixes the reinforcing bars. Similarly, following the above process, the fastener 15 clamps and secures the reinforcing bars, fixing the reinforcing mesh 7. Simultaneously, the edge of the fastener 15 presses against the bending position of the reinforcing mesh 7. The first hydraulic rod 14 is opened, and the first hydraulic rod 14 rotates on the side wall of the base 61, simultaneously driving the forward bending head 13 to rotate upward and press the reinforcing mesh 7, bending the reinforcing mesh 7 in the forward direction. The mesh moving vehicle 3 is used to adjust the bending position of the mesh, and the above clamping and bending actions are repeated to form a suitable reinforcing bar skeleton for the reinforcing mesh 7.

[0035] Both the feeding rack 4 and the finished product collection rack 5 are equipped with mesh moving carts 3 on their outer sides. Each mesh moving cart 3 includes a frame 31. A crossbeam 32 for moving the reinforcing mesh 7 left and right is slidably connected to the surface of the frame 31. A column 33 for moving the reinforcing mesh 7 back and forth is provided on the side wall of the crossbeam 32. Multiple clamps 37 for clamping the reinforcing mesh 7 are rotatably connected to the bottom end of the column 33. The moving mechanism 8 includes a gear 81, a rack 82, a third roller 83, and a motor 84. The gear 81 is mounted on one side of the motor 84, and the gear 81 meshes with the rack 82. The frame... The moving mechanism 8 is installed between the frame 31 and the crossbeam 32 and between the crossbeam 32 and the column 33. The rack 82 is installed on the side wall of both the frame 31 and the crossbeam 32. The motor 84 and the third roller 83 are respectively installed on the side wall of the crossbeam 32. The third roller 83 is slidably connected to the side wall of the frame 31. When the crossbeam 32 moves along the frame 31, the motor 84 on the side wall of the crossbeam 32 operates to drive the gear 81 to rotate. The gear 81 moves along the rack 82 and simultaneously drives the third roller 83 to move along the frame 31.

[0036] The mesh moving vehicle 3 also includes a fixing plate 34, on which the motor 84 is installed on both side walls. A first roller 35 is installed on the side wall of the fixing plate 34, and the first roller 35 is slidably connected to the crossbeam 32. A rack 82 is installed on the side wall of the column 33, and the rack 82 meshes with the gear 81 on one side of the fixing plate 34. A limiting mechanism 9 is installed between the column 33 and the fixing plate 34. The limiting mechanism 9 includes a guide rail 91, which is fixed to the side wall of the column 33. The guide rail 91 is internally engaged with and slidably connected to a slide rod 94, which is fixed to the side wall of the fixing plate 34. A fourth hydraulic rod 92 for limiting the column 33 is installed on the side wall of the fixing plate 34. A retaining strip 93 is installed on one side of the fourth hydraulic rod 92. The retaining strip 93 is slidably connected to the slide rod 94, and the retaining strip 93 engages with the rack 82 on the side wall of the column 33. When the column 33 slides against the side wall of the crossbeam 32, the motor 84 on one side of the fixing plate 34 drives the gear 81 to rotate. The gear 81 moves along the rack 82 inside the crossbeam 32, simultaneously driving the third roller 83 to move along the crossbeam 32, pushing the fixing plate 34 and the column 33 to move along the direction of the crossbeam 32. The fixing plate 34 drives the first roller 35 to move along the crossbeam 32. The first roller 35 at the top of the fixing plate 34 prevents the fixing plate 34 from detaching from the crossbeam 32. The first roller 35 at the top of the fixing plate 34 bears the weight of the column 33 and the steel mesh 7, thereby facilitating the movement of the fixing plate 34. When it is necessary to change the height of the column 33... The operation of the fourth hydraulic rod 92 causes the locking strip 93 to separate from the rack 82 on the side wall of the column 33. The operation of the motor 84 on the other side of the fixing plate 34 drives the gear 81 to rotate. The gear 81 pushes the rack 82 and the column 33 to move, changing the height of the column 33. At the same time, the guide rail 91 on the side wall of the column 33 slides inside the slide rod 94 to prevent the position from shifting when the column 33 moves. When the height of the column 33 is appropriate, the operation of the fourth hydraulic rod 92 causes the locking strip 93 to move along the side wall of the slide rod 94 and engage the rack 82 on the side wall of the column 33, thereby fixing the column 33 and directly transferring the weight of the column 33 to the slide rod 94 and the fixing plate 34.

[0037] The mesh moving vehicle 3 also includes a third hydraulic rod 36. Multiple third hydraulic rods 36 are symmetrically installed at the bottom of each column 33. A compression sleeve 38 for closing the clamp 37 is installed at the bottom of each third hydraulic rod 36. The compression sleeve 38 is slidably connected to the side wall of the clamp 37, and a spring 39 for resetting the clamp 37 is installed at the top of the clamp 37. When it is necessary to clamp the steel mesh 7, the column 33 drives the clamp 37 to move, allowing the steel bars to enter the interior of the clamp 37, opening the third hydraulic rod 36. The third hydraulic rod 36 retracts, driving the compression sleeve 38 to move upward and compress the clamp 37. The clamp 37 closes and clamps the steel bars while compressing the spring 39. The clamp 39 clamps the steel bars, facilitating the movement of the steel cage 7.

[0038] Both the forward bending machine 1 and the reverse bending machine 2 are equipped with a translation mechanism 6 at their bottom ends to change their positions. The mesh moving vehicle 3 and the side walls of the translation mechanism 6 are both equipped with a moving mechanism 8. The translation mechanism 6 includes a base 61, a ground rail 62, and the moving mechanism 8. The base 61 is installed at the bottom ends of both the forward bending machine 1 and the reverse bending machine 2. The motor 84 and the third roller 83 are installed inside the base 61. The rack 82 is installed inside the ground rail 62, and the third roller 83 is slidably connected to the ground rail 62. When the forward bending machine 1 and the reverse bending machine 2 move, the motor 82 inside the base 61 drives the gear 81 to rotate. The gear 81 moves along the rack 82 inside the ground rail 62, simultaneously pushing the third roller 83 inside the base 61 to move within the ground rail 62, thereby changing the positions of the forward bending machine 1 and the reverse bending machine 2.

[0039] A processing method for automatically bending both ends of a steel mesh in both directions, specifically including the following steps:

[0040] Step 1: First, place the steel mesh 7 to be processed on the loading rack 4. Connect the power supply to the device. When gripping the steel mesh 7, the motor 84 on the side wall of the crossbeam 32 operates, driving the gear 81 to rotate. The gear 81 moves along the rack 82, simultaneously driving the third roller 83 to move along the frame 31. The crossbeam 32 and the column 33 move left and right. The motor 84 on one side of the fixing plate 34 operates, driving the gear 81 to rotate. The gear 81 moves along the rack 82 inside the crossbeam 32, simultaneously driving the third roller 83 to move along the crossbeam 32, pushing the fixing plate 34 and the column 33. The column 33 moves back and forth along the direction of the crossbeam 32, and the movement of the column 33 in all directions aligns the clamp 37 with the reinforcing bar. Then, the fourth hydraulic rod 92 is opened, and the operation of the fourth hydraulic rod 92 causes the locking strip 93 to separate from the rack 82 on the side wall of the column 33. The motor 84 on the other side of the fixing plate 34 drives the gear 81 to rotate. The gear 81 pushes the rack 82 and the column 33 to move, changing the height of the column 33. At the same time, the guide rail 91 on the side wall of the column 33 slides inside the sliding rod 94 to prevent the position from shifting when the column 33 moves. When the reinforcing bar enters the... After entering the clamp 37, the fourth hydraulic rod 92 operates, driving the locking strip 93 to move along the side wall of the slide rod 94 and engage the rack 82 on the side wall of the column 33, thereby fixing the column 33. The column 33 drives the clamp 37 to move, allowing the reinforcing bar to enter the clamp 37. The third hydraulic rod 36 opens, and the third hydraulic rod 36 retracts, driving the extrusion sleeve 38 to move upward and extrude the clamp 37. The clamp 37 closes, clamping the reinforcing bar and compressing the spring 39 at the same time. The clamp 39 holds the reinforcing bar, facilitating the movement of the reinforcing bar cage 7. Similarly, the movement of the crossbeam 32 and the column 33 moves the material feeding mechanism. The steel mesh 7 on the surface of the frame 4 is gripped and placed on the surface of the lower support beam 12. The surface of the first fixed frame 11 is rotatably connected to the lower support beam 12. When adjusting the position of the steel mesh 7, the steel mesh 7 moves on the surface of the lower support beam 12 and drives the lower support beam 12 to rotate, reducing the resistance when the steel mesh 7 moves, so that the steel mesh 7 reaches the predetermined position. The translation mechanism 6 drives the forward bending machine 1 and the reverse bending machine 2 to move. At the same time, the mesh moving car 3 adjusts the position of the steel mesh 7 so that the steel mesh 7 is aligned with the forward bending machine 1 and the reverse bending machine 2.

[0041] Step Two: Before the reverse bending, the reinforcing mesh 7 reaches the bending position, and the bending position of the reinforcing mesh 7 is aligned with the upper fixed beam 24; the mesh moving vehicle 3 grabs and fixes the reinforcing bars, the translation mechanism 6 drives the forward bending machine 1 to move so that the fastener 15 is misaligned with the reinforcing bars, the first hydraulic rod 14 is opened, the first hydraulic rod 14 pushes the fixed beam 16 and the fastener 15 upward, so that the fastener passes through the gap between the reinforcing bars, the translation mechanism 6 is opened so that the fastener 15 moves to align with the reinforcing bars, the first hydraulic rod 14 retracts and drives the fastener 15 downward, the fastener 15 has a groove on its side wall. The reinforcing bar enters the slot, allowing the fastener 15 and the lower support beam 12 to fix the reinforcing mesh 7, achieving reverse bending positioning, increasing the stability of the reinforcing mesh 7 during processing, and preventing misalignment of the reinforcing mesh 7; the operation of the second hydraulic rod 22 on the side wall of the second fixing frame 21 drives the upper fixing beam 24 to move, causing the upper fixing beam 24 to press the bent position of the reinforcing mesh 7, opening the second hydraulic rod 22 on the surface of the third fixing frame 23, and the second hydraulic rod 22 drives the reverse bending head 25 to rotate downward, causing the reverse bending head 25 to press the reinforcing mesh 7 downward, bending the reinforcing mesh 7 in the reverse direction;

[0042] Step 3: When bending forward, the mesh moving cart 3 swings to adjust the reinforcing mesh 7 so that the bending position of the reinforcing mesh 7 is aligned with the edge of the fastener 15; the mesh moving cart 3 then grabs and fixes the reinforcing bar, and similarly follows Step 2 to make the fastener 15 fasten and clamp the reinforcing bar, fixing the reinforcing mesh 7. At the same time, the edge of the fastener 15 presses the bending position of the reinforcing mesh 7, and the first hydraulic rod 14 is opened. The first hydraulic rod 14 rotates on the side wall of the base 61 and drives the forward bending head 13 to rotate upward to press the reinforcing mesh 7, bending the reinforcing mesh 7 in the forward direction; the mesh moving cart 3 is used to adjust the bending position of the mesh, and the above clamping and bending actions are repeated.

[0043] Step 4: The bent steel reinforcement cage is picked up and transported to the finished product collection rack 5 by two sets of mesh moving vehicles 3 along the direction of the frame 31.

[0044] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.

8. A processing method for automatically bending both ends of a steel mesh in both directions, used in the automatic bending equipment for both ends of the steel mesh as described in claim 7, characterized in that, Includes the following steps: Step 1: First, the steel mesh (7) to be processed is placed on the loading rack (4). The steel mesh (7) is picked up and loaded along the longitudinal direction by two sets of mesh moving carts (3). The surface of the first fixed frame (11) is rotatably connected to the lower support beam (12). The steel mesh (7) moves on the surface of the lower support beam (12) and drives the lower support beam (12) to rotate, so that the steel mesh (7) reaches the predetermined position. The translation mechanism (6) drives the forward bending machine (1) and the reverse bending machine (2) to move. At the same time, the mesh moving cart (3) adjusts the position of the steel mesh (7) so that the steel mesh (7) is aligned with the forward bending machine (1) and the reverse bending machine (2). Step 2: Before the reverse bending, the steel mesh (7) reaches the bending position, and the bending position of the steel mesh (7) is aligned with the upper fixed beam (24); the mesh moving vehicle (3) grabs and fixes the steel bar, and the translation mechanism (6) drives the forward bending machine (1) to move so that the fastener (15) is misaligned with the steel bar. The first hydraulic rod (14) is opened, and the first hydraulic rod (14) pushes the fixed beam (16) and the fastener (15) to move upward, so that the fastener passes through the gap between the steel bars. The translation mechanism (6) is opened so that the fastener (15) moves to align with the steel bar. The first hydraulic rod (14) retracts and drives the fastener (15) to move downward. The side wall of the fastener (15) is provided with a slot. The reinforcing bar enters the slot, allowing the fastener (15) and the lower support beam (12) to fix the reinforcing mesh (7), achieving reverse bending positioning, increasing the stability of the reinforcing mesh (7) during processing, and preventing the reinforcing mesh (7) from being misaligned; the second hydraulic rod (22) on the side wall of the second fixing frame (21) operates to drive the upper fixing beam (24) to move, causing the upper fixing beam (24) to press the bending position of the reinforcing mesh (7), opening the second hydraulic rod (22) on the surface of the third fixing frame (23), and the second hydraulic rod (22) drives the reverse bending head (25) to rotate downward, causing the reverse bending head (25) to press the reinforcing mesh (7) downward, and bending the reinforcing mesh (7) in the reverse direction; Step 3: When bending forward, the mesh moving cart (3) swings to adjust the steel mesh (7) so that the bending position of the steel mesh (7) is aligned with the edge of the fastener (15); the mesh moving cart (3) then grabs and fixes the steel bar, and similarly follows step 2 to make the fastener (15) fasten and clamp the steel bar to fix the steel mesh (7). At the same time, the edge of the fastener (15) presses the bending position of the steel mesh (7), and the first hydraulic rod (14) is opened. The first hydraulic rod (14) rotates on the side wall of the base (61) and drives the forward bending head (13) to rotate upward to press the steel mesh (7) and bend the steel mesh (7) in the forward direction; the mesh moving cart (3) is used to adjust the bending position of the mesh, and the above clamping and bending actions are repeated.
