Description

Technical Field

[0001] This invention belongs to the technical field of wire feeding mechanism and wire feeding method, and particularly relates to a wavy wire bending and feeding mechanism for wavy wire mesh welding line and a method for bending and feeding wire using the device. Background Technology

[0002] The corrugated wire mesh includes corrugated wires and drag bars located at the bottom of the corrugated wires. Side guard bars welded to the corrugated wires are provided on both sides of the corrugated wires, and end bars welded to the drag bars are provided at both ends of the corrugated wires. Patent No. 202311853349.5, entitled "Apparatus for Producing Corrugated Wires for Shelf Mesh and Method for Producing Corrugated Wires Using the Apparatus," discloses a mechanism for bending and feeding corrugated wires. The feeding mechanism includes two parallel lower comb plates arranged in a front-to-back direction on a fixed frame. Each lower comb plate has an upward-opening lower comb groove. The lower comb plates are connected to the fixed frame via a lower comb plate lifting mechanism. An upper comb plate frame is provided above the lower comb plates. Two parallel upper comb plates that can move back and forth along the upper comb plate frame are provided on the upper comb plate frame. Each upper comb plate has a downward-opening upper comb groove. The upper comb plate frame is connected to the fixed frame via an upper comb plate lifting mechanism. The upper comb plate presses down, causing the bent wavy filaments to enter the upper comb groove of the upper comb plate. The lower comb plate moves downward, causing the bent wavy filaments to disengage from the lower comb groove. The upper comb plate moves the bent filaments forward by the length of two "U"-shaped filaments. At this point, the 90-degree bend of the filaments just passes around the second right bending post from the right side. The lower comb plate moves upward, causing the bent wavy filaments to enter the lower comb groove. The upper comb plate moves upward, and the filaments move out of the upper comb groove of the upper comb plate. The upper comb plate moves backward by the length of two "U"-shaped filaments to reset. The above-mentioned wire feeding and bending device has the following defects: First, the lower comb plate moves up and down, while the upper comb plate moves not only up and down but also back and forth, making the equipment bulky and energy-intensive; Second, the wavy wire is located between the upper and lower comb plates, resulting in poor equipment openness, making it difficult to detect situations such as tangled wires, and hindering equipment maintenance; Third, the lower comb plate moves up and down, while the upper comb plate moves not only up and down but also back and forth, resulting in low reciprocating efficiency and low mesh welding efficiency. Summary of the Invention

[0003] The first technical problem to be solved by this invention is to provide a corrugated wire bending and feeding mechanism for corrugated wire mesh welding lines that is simple in structure, consumes little energy, has good equipment development capabilities, is easy to repair and maintain, makes it easy to detect problems such as tangled wires in the corrugated wire in a timely manner, and has high production efficiency.

[0004] To solve the above problems, the technical solution adopted by the corrugated wire bending and feeding mechanism for corrugated wire mesh welding line of the present invention is as follows: It includes a frame, on which a wire bending mechanism is arranged; a wire pushing mechanism is arranged on the side of the wire bending mechanism; a wire feeding mechanism is arranged in front of the wire pushing mechanism; and a longitudinal wire frame with longitudinal wire through holes is arranged on the frame above the wire feeding mechanism. The frame has a wire bending and pushing track, and a wire bending and pushing frame that can move back and forth along the track is arranged on the track. The wire bending mechanism is located near the rear of the wire bending and pushing frame, and the wire pushing mechanism is located on the wire bending and pushing frame in front of the wire bending mechanism. The wire bending and pushing frame is connected to the frame via a push-pull mechanism. The push-pull mechanism includes a first motor located on the frame and a lead screw connected to the first motor. A lead screw nut matching the lead screw is arranged on the wire bending and pushing frame. The wire pushing mechanism includes a push frame body, and a push plate is arranged in front of the push frame body. The rear end is movably connected to the wire pusher frame. Limiting slots are arranged along the front-to-back direction near the pusher plate. A lifting cylinder is installed on the wire pusher frame above the pusher plate, with its top rod connected to the pusher plate. A wire pusher support plate is installed in front of the wire pusher frame, and a spring clip frame is installed above the wire pusher support plate. At least two limiting spring clips are spaced apart along the front-to-back direction on the spring clip frame. An inverted "V"-shaped temporary limiting groove is provided below each limiting spring clip, and the lower end of each limiting spring clip contacts the wire pusher support plate. The wire feeding mechanism includes a wire feeding frame and a wire feeding power mechanism. A wire feeding gear is installed on the wire feeding frame, and a wire feeding chain is installed on the wire feeding gear. Limiting paddles are installed on the wire feeding chain. The wire feeding power mechanism includes a chain push-pull rod located in front of the wire folding and pushing frame. The chain push-pull rod is fixed to a power chain, which passes around a one-way drive sprocket. The drive shaft of the one-way drive sprocket is poweredly connected to the wire feeding gear.

[0005] Its additional technical features are:

[0006] There are two chain push-pull rods arranged in a front and rear configuration. Each chain push-pull rod is connected to both ends of the drive chain. A tensioning mechanism is provided between the two chain push-pull rods.

[0007] The tensioning mechanism includes a fixed base plate, a strip groove is provided at the corresponding position of the fixed base plate and the chain push-pull rod, a slide rod with lock nuts at both ends is provided in the strip groove, a tensioning rod is provided between the two chain push-pull rods, and tensioning nuts are provided at both ends of the tensioning rod.

[0008] The lower part of the limiting spring is W-shaped;

[0009] A corrugated wire guide plate is provided on the longitudinal wire frame below the longitudinal wire through hole.

[0010] The second technical problem to be solved by the present invention is to provide a method for bending and feeding wire using the above-mentioned corrugated wire bending and feeding mechanism for corrugated wire mesh welding lines.

[0011] To solve the above problems, the technical solution adopted by the present invention for bending and feeding the corrugated wire using the above-mentioned corrugated wire bending and feeding mechanism for corrugated wire mesh welding lines is as follows:

[0012] The method includes the following steps:

[0013] Step 1, straighten

[0014] The metal wire is straightened by the straightening mechanism.

[0015] The second step is to fold the threads.

[0016] The straightened metal wire is bent into a wavy wire using a wire bending mechanism;

[0017] Third step, lift the front end of the push plate.

[0018] The lifting cylinder drives the front end of the push plate to swing upward, causing the lower end of the push plate to be higher than the upper edge of the corrugated wire.

[0019] Fourth step, the wire bending and pushing frame is reset to its original position.

[0020] The first motor drives the lead screw to rotate, causing the wire bending and pushing frame to move backward. The chain push rod in front of the wire bending and pushing frame moves backward, driving the upper end of the power chain to move backward. The one-way transmission sprocket spins backward, while the transmission shaft and wire feeding gear do not rotate, and the wire feeding chain and limit plate do not move.

[0021] Fifth step, the front end of the push plate swings downward, and the limit slot locks the corrugated wire.

[0022] The lifting cylinder drives the front end of the push plate to swing downward, so that the bent corrugated wire is located in the limiting groove at the lower end of the push plate.

[0023] Step 6: Move the wavy silk forward.

[0024] The first motor drives the lead screw to rotate, causing the wire folding and pushing frame to move forward. This moves the push plate and the corrugated wire located in the limit slot on the push plate forward. The chain push rod in front of the wire folding and pushing frame moves forward, causing the upper end of the power chain to move forward. The one-way transmission sprocket drives the transmission shaft and the wire feeding gear to rotate, causing the wire feeding chain, the limit plate, and the corrugated wire to move forward.

[0025] The corrugated wire in the limiting slot moves forward along the pusher plate. The front end of the corrugated wire abuts against the rear end of the limiting spring, causing the limiting spring to move upward and the corrugated wire to be stuck in the temporary limiting slot at the lower end of the limiting spring.

[0026] The chain push rod in front of the wire bending and pushing frame moves forward, driving the upper end of the power chain to move forward. The one-way transmission sprocket drives the transmission shaft and the wire feeding gear to rotate, driving the wire feeding chain and the limit plate to move forward. The wavy wire in the temporary limit groove at the front enters between the adjacent limit plates of the chain and is pushed forward by the limit plate behind. The wavy wire in the temporary limit groove pushes the limit spring forward. The lower end of the limit spring swings forward and upward, causing the wavy wire in the temporary limit groove to move forward out of the temporary limit groove. The limit spring returns to its original position under its own elastic force, and the wavy wire behind re-enters the temporary limit groove of the limit spring.

[0027] Step 7: Repeat steps 2 through 6. The bent wavy wire is fed to the welding head by the limit plate of the wire feeding chain and welded to the longitudinal wire to form a mesh.

[0028] The corrugated wire bending and feeding mechanism and method for corrugated wire mesh welding wire provided by this invention have the following advantages compared with the prior art:

[0029] Firstly, the device includes a frame, on which a wire-folding mechanism is mounted, a wire-pushing mechanism is mounted on the side of the wire-folding mechanism, and a wire-feeding mechanism is mounted in front of the wire-pushing mechanism. Above the wire-feeding mechanism, a longitudinal wire frame with longitudinal wire through holes is mounted on the frame. The frame has a wire-folding and wire-pushing track, on which a wire-folding and wire-pushing frame that can move back and forth is mounted. The wire-folding mechanism is located near the rear of the wire-folding and wire-pushing frame, and the wire-pushing mechanism is located on the wire-folding and wire-pushing frame in front of the wire-folding mechanism. The wire-folding and wire-pushing frame is connected to the frame via a push-pull mechanism. The push-pull mechanism includes a first motor located on the frame and a lead screw connected to the first motor. During the wire-folding and wire-pushing... The frame is equipped with a lead screw nut that matches the lead screw; the wire pushing mechanism includes a wire pushing frame body, a push plate is provided in front of the wire pushing frame body, the rear end of the push plate is movably connected to the wire pushing frame body, limit slots are arranged along the front-to-back direction near the lower part of the push plate, a lifting cylinder is provided on the wire pushing frame body above the push plate, the top rod of the lifting cylinder is connected to the push plate, a wire pushing support plate is provided in front of the wire pushing frame body, a spring plate frame is provided above the wire pushing support plate, at least two limit springs are arranged at intervals along the front-to-back direction on the spring plate frame, an inverted "V" shaped temporary limit groove is provided below the limit springs, and the lower end of the limit springs contacts the wire pushing support plate; the wire feeding mechanism includes a wire feeding frame body and a wire feeding mechanism. The mechanism includes a wire feeding gear mounted on the wire feeding frame, a wire feeding chain mounted on the wire feeding gear, and a limit switch on the wire feeding chain. The wire feeding power mechanism includes a chain push-pull rod located in front of the wire bending and pushing frame. The chain push-pull rod is fixed to a power chain, which passes around a one-way drive sprocket. The drive shaft of the one-way drive sprocket is poweredly connected to the wire feeding gear. The wire bending mechanism bends the straightened metal wire into a wavy wire. A lifting cylinder drives the front end of the push plate to swing upwards, causing the lower end of the push plate to be higher than the upper edge of the wavy wire. A first motor drives the lead screw to rotate, causing the wire bending and pushing frame to move backwards. The chain push-pull rod in front of the wire bending and pushing frame moves backwards, causing the upper end of the power chain to move backwards. The one-way drive sprocket... The machine rotates backwards without moving the drive shaft and wire feeding gear, and the wire feeding chain and limit plate do not move. The lifting cylinder drives the front end of the push plate to swing downwards, so that the bent corrugated wire is located in the limit slot at the lower end of the push plate. The first motor drives the lead screw to rotate, so that the wire bending and pushing frame moves forward, driving the push plate and the corrugated wire in the limit slot on the push plate to move forward. The chain push rod in front of the wire bending and pushing frame moves forward, driving the upper end of the power chain to move forward. The one-way transmission sprocket drives the drive shaft and wire feeding gear to rotate, driving the wire feeding chain, limit plate and corrugated wire to move forward. The corrugated wire in the limit slot moves forward along the push plate. The front end of the corrugated wire hits the rear end of the limit spring, so that the limit spring moves upward and the corrugated wire is stuck in the temporary limit slot at the lower end of the limit spring.The chain push-pull rod in front of the wire bending and pushing frame moves forward, driving the upper end of the power chain forward. The one-way transmission sprocket drives the drive shaft and wire feeding gear to rotate, driving the wire feeding chain and the limiting plate forward. The corrugated wire in the temporary limiting groove at the front enters between the adjacent limiting plates of the chain and is pushed forward by the limiting plate behind. The corrugated wire in the temporary limiting groove pushes the limiting spring forward, and the lower end of the limiting spring swings forward and upward, causing the corrugated wire in the temporary limiting groove to move forward out of the temporary limiting groove. The limiting spring returns to its original position under its own elastic force, and the next corrugated wire enters the temporary limiting groove from the rear. The bent corrugated wire is sent to the welding head position by the limiting plate of the wire feeding chain and welded with the longitudinal wire to form a mesh.

[0030] Advantage 1: The wavy wire after bending by the bending mechanism is located in the limiting slot at the lower end of the push plate, which avoids the wire from becoming tangled due to its own elasticity.

[0031] Advantage 2: When the push plate pushes the corrugated wire in the limiting slot forward, the front end of the corrugated wire located behind the limiting spring plate presses against the rear end of the limiting spring plate, causing the limiting spring plate to move upward. The corrugated wire then gets stuck in the temporary limiting groove at the lower end of the limiting spring plate. The limiting spring plate returns to its original position under its own elasticity. At this time, the corrugated wire is firmly restricted in the temporary limiting groove and cannot come out of the temporary limiting groove due to the elasticity of the metal wire itself. When the corrugated wire is pushed forward again, the front end of the limiting spring plate opens under external force, allowing the corrugated wire to move out of the temporary limiting groove. The limiting spring plate returns to its original position under its own elasticity, and the next corrugated wire enters the temporary limiting groove from the rear. The limiting spring plate with the temporary limiting groove can temporarily fix the corrugated wire, making it more convenient to use.

[0032] Advantage 3: The bent corrugated wire is fed to the welding head position by the limit plate of the wire feeding chain. The corrugated wire is stuck between the limit plates, and no wire tangling occurs between adjacent corrugated wires during the wire feeding process.

[0033] Advantage 4: The wire feeding power mechanism includes a chain push-pull rod located in front of the wire folding and pushing frame. The chain push-pull rod is fixed to the power chain, which passes over a one-way drive sprocket. The drive shaft of this one-way drive sprocket is poweredly connected to the wire feeding gear. When the wire folding and pushing frame moves backward, the chain push-pull rod in front of the frame moves backward, causing the upper end of the power chain to move backward. The one-way drive sprocket rotates backward, while the drive shaft and wire feeding gear do not rotate, and the wire feeding chain and limit plate do not move. The wire pusher moves forward, driving the push plate and the corrugated wire in the limiting slot of the push plate forward. The chain push rod in front of the wire folding pusher moves forward, driving the upper end of the power chain to move forward. The one-way transmission sprocket drives the transmission shaft and the wire feeding gear to rotate, driving the wire feeding chain, the limiting plate and the corrugated wire to move forward. The corrugated wire moves forward together with the wire folding pusher. When the wire folding pusher moves backward, the wire feeding chain and the limiting plate do not move, ensuring the synchronization of wire feeding and wire folding. The structure is simple.

[0034] Fifthly, during the wire feeding process, the wavy wire is located at the upper end of the wire feeding chain, and the entire state of the wavy wire can be clearly seen. When tangled wires occur, they are easy to detect and handle. The entire equipment has good openness, making maintenance and repair easier.

[0035] Secondly, since there are two chain push-pull rods arranged in front and behind, each chain push-pull rod is connected to both ends of the power chain, and a tensioning mechanism is provided between the two chain push-pull rods, so that the power chain is in a tensioned state, ensuring the synchronization of wire feeding and wire folding;

[0036] Thirdly, since the tensioning mechanism includes a fixed base plate, a strip groove is provided at the corresponding position of the fixed base plate and the chain push-pull rod, a slide rod with lock nuts at both ends is provided in the strip groove, a tensioning rod is provided between the two chain push-pull rods, and tensioning nuts are provided at both ends of the tensioning rod, making adjustment more convenient.

[0037] Fourth, since the lower part of the limiting spring is "W" shaped, the front and rear ends of the lower part of the limiting spring are both inclined, and the wavy wire can easily open the limiting spring and enter the temporary limiting groove from the back of the limiting spring. Moreover, the noise is smaller when the wavy wire moves out of the temporary limiting groove.

[0038] Fifth, since a corrugated wire guide plate is provided on the longitudinal wire frame below the longitudinal wire through hole, the corrugated wire that has disengaged from the temporary limiting groove can be pressed down, preventing the corrugated wire from popping out of the chain derailleur.

A spring plate frame 19 is provided above the wire pushing support plate 18. At least two limiting spring plates 20 are arranged at intervals in the front-to-back direction on the spring plate frame 19. An inverted "V" shaped temporary limiting groove 21 is provided below the limiting spring plate 20. The lower end of the limiting spring plate 20 contacts the wire pushing support plate 18.

[0052] The wire feeding mechanism 4 includes a wire feeding frame 22 and a wire feeding power mechanism 23. A wire feeding gear 24 is provided on the wire feeding frame 22, a wire feeding chain 25 is provided on the wire feeding gear 24, and a limit plate 26 is provided on the wire feeding chain 25. The wire feeding power mechanism includes a chain push-pull rod 27 located in front of the wire folding and pushing frame 8. The chain push-pull rod 27 is fixed to the power chain 28. The power chain 28 passes around a one-way transmission sprocket 29. The transmission shaft 30 of the one-way transmission sprocket 29 is poweredly connected to the wire feeding gear 24.

[0053] The straightened metal wire is bent into a wavy wire 39 by the wire bending mechanism 2; the lifting cylinder 16 drives the front end of the push plate 14 to swing upward, so that the lower end of the push plate 14 is higher than the upper edge of the wavy wire 39; the first motor 10 drives the lead screw 11 to rotate, so that the wire bending and pushing frame 8 moves backward, the chain push rod 27 in front of the wire bending and pushing frame 8 moves backward, driving the upper end of the power chain 28 to move backward, the one-way transmission sprocket 29 spins backward, the transmission shaft 30 and the wire feeding gear 24 do not rotate, and the wire feeding chain 25 and the limit plate 26 do not move; the lifting cylinder 16 drives the lead screw 11 to rotate, so that the lead screw 11 moves backward, causing the lead screw 11 to rotate backward, the drive shaft 30 and the wire feeding gear 24 do not rotate, and the wire feeding chain 25 and the limit plate 26 do not move; the lifting cylinder 16 drives the lead screw 11 to rotate backward, causing ... The front end of the push plate 14 swings downward, causing the bent corrugated wire to be located in the limiting slot 15 at the lower end of the push plate 14. The first motor 10 drives the lead screw 11 to rotate, causing the wire bending and pushing frame 8 to move forward, driving the push plate 14 and the corrugated wire located in the limiting slot 15 of the push plate 14 to move forward. The chain push rod 27 in front of the wire bending and pushing frame 8 moves forward, driving the upper end of the power chain 28 to move forward. The one-way transmission sprocket 29 drives the transmission shaft 30 and the wire feeding gear 24 to rotate, driving the wire feeding chain 25, the limiting plate 26, and the corrugated wire to move forward. The corrugated wire in the limiting slot 15 moves forward along the pusher plate 14. The front end of the corrugated wire abuts against the rear end of the limiting spring 20, causing the limiting spring 20 to move upward. The corrugated wire is then stuck in the temporary limiting slot 21 at the lower end of the limiting spring 20. The chain push rod 27 in front of the wire folding and pushing frame 7 moves forward, driving the upper end of the power chain 28 to move forward. The one-way transmission sprocket 29 drives the transmission shaft 30 and the wire feeding gear 24 to rotate, driving the wire feeding chain 25 and the limiting plate 26 to move forward. The corrugated wire in the foremost temporary limiting slot 21 then enters... The wavy wire is pushed forward by the rear limit plate 26 between the adjacent limit plates 26 of the feeding chain. The wavy wire in the temporary limit groove 21 pushes the limit spring 20 forward. The lower end of the limit spring 20 swings forward and upward, causing the wavy wire in the temporary limit groove 21 to move forward out of the temporary limit groove 21. The limit spring returns to its original position under its own elastic force, and the next wavy wire enters the temporary limit groove 21 from the rear. The bent wavy wire is sent to the welding head position by the limit plate of the wire feeding chain and welded with the longitudinal wire to form a mesh.

[0054] Advantage 1: The wavy wire after bending by the bending mechanism is located in the limiting groove 15 at the lower end of the push plate 14, which avoids the wire from becoming tangled due to its own elasticity.

[0055] Advantage 2: When the push plate 14 pushes the corrugated wire in the limiting slot 15 forward, the front end of the corrugated wire located behind the limiting spring 20 presses against the rear end of the limiting spring 20, causing the limiting spring 20 to move upward. The corrugated wire gets stuck in the temporary limiting groove 21 at the lower end of the limiting spring 20. The limiting spring 20 returns to its original position under its own elasticity. At this time, the corrugated wire is firmly restricted in the temporary limiting groove 21 and cannot come out of the temporary limiting groove 21 due to the elasticity of the metal wire itself. When the corrugated wire is pushed forward again, the front end of the limiting spring 20 opens under external force, allowing the corrugated wire to move out of the temporary limiting groove 21. The limiting spring 20 returns to its original position under its own elasticity, and the next corrugated wire enters the temporary limiting groove 21 from the rear. The limiting spring with the temporary limiting groove can temporarily fix the corrugated wire, making it more convenient to use.

[0056] Advantage 3: The bent corrugated wire is fed to the welding head position by the limiting plate 26 of the wire feeding chain 25. The corrugated wire is stuck between the limiting plates 26, and no wire tangling occurs between adjacent corrugated wires during the wire feeding process.

[0057] Advantage 4: The wire feeding power mechanism includes a chain push-pull rod 27 located in front of the wire folding and pushing frame 8. The chain push-pull rod 27 is fixed to the power chain 28. The power chain 28 passes around the one-way transmission sprocket 29. The transmission shaft 30 of the one-way transmission sprocket 29 is poweredly connected to the wire feeding gear 24. When the wire folding and pushing frame 8 moves backward, the chain push-pull rod 27 in front of the wire folding and pushing frame 8 moves backward, driving the upper end of the power chain to move backward. The one-way transmission sprocket 29 rotates backward, and the transmission shaft 30 and the wire feeding gear 24 do not rotate. The wire feeding chain 25 and the limit plate 26 do not move. The wire folding and pushing frame 8 moves forward, driving the push plate 14 and the corrugated wire in the limiting slot 15 of the push plate 14 to move forward. The chain push rod in front of the wire folding and pushing frame 8 moves forward, driving the upper end of the power chain 28 to move forward. The one-way transmission sprocket 29 drives the transmission shaft 30 and the wire feeding gear 24 to rotate, driving the wire feeding chain 25, the limiting plate 26 and the corrugated wire to move forward. The corrugated wire moves forward together with the wire folding and pushing frame. When the wire folding and pushing frame 8 moves backward, the wire feeding chain and the limiting plate do not move, ensuring the synchronization of wire feeding and wire folding. The structure is simple.

[0058] Fifthly, during the wire feeding process, the wavy wire is located at the upper end of the wire feeding chain 25, and the entire state of the wavy wire can be clearly seen. When tangled wires occur, they are easy to detect and handle. The entire equipment has good openness, making maintenance and repair easier.

[0059] There are two chain push-pull rods 27 arranged at the front and rear. Each chain push-pull rod 27 is connected to both ends of the drive chain 28. A tensioning mechanism 31 is provided between the two chain push-pull rods 27 to keep the drive chain in a tensioned state, ensuring the synchronization of wire feeding and wire folding.

[0060] The tensioning mechanism 31 includes a fixed base plate 32, a strip groove 33 is provided at the corresponding positions of the fixed base plate 32 and the chain push-pull rod 27, a slide rod 35 with lock nuts 34 at both ends is provided in the strip groove 33, a tensioning rod 36 is provided between the two chain push-pull rods 27, and tensioning nuts 37 are provided at both ends of the tensioning rod 36, making adjustment more convenient;

[0061] The lower part of the limiting spring 20 is "W" shaped, so that the front and rear ends of the lower part of the limiting spring 20 are both inclined. The wavy wire can easily open the limiting spring and enter the temporary limiting groove 21 from the back of the limiting spring. Moreover, the noise is smaller when the wavy wire moves out of the temporary limiting groove.

[0062] A corrugated wire guide plate 38 is provided on the longitudinal wire frame 6 below the longitudinal wire through hole 5, which can press the corrugated wire that has been removed from the temporary limiting groove to prevent the corrugated wire from popping out of the chain derailleur.

[0063] The technical solution adopted in the above-mentioned method of bending and feeding corrugated wires using the corrugated wire bending and feeding mechanism for corrugated wire mesh welding lines is as follows:

[0064] The method includes the following steps:

[0065] Step 1, straighten

[0066] The metal wire is straightened by the straightening mechanism.

[0067] The second step is to fold the threads.

[0068] The straightened metal wire is bent into a wavy wire by the wire bending mechanism 2;

[0069] Third step, lift the front end of the push plate.

[0070] The lifting cylinder 16 drives the front end of the push plate 14 to swing upward, causing the lower end of the push plate 14 to be higher than the upper edge of the corrugated wire.

[0071] Fourth step, the wire bending and pushing frame is reset to its original position.

[0072] The first motor 10 drives the lead screw 11 to rotate, causing the wire bending and pushing frame 8 to move backward. The chain push rod 27 in front of the wire bending and pushing frame 8 moves backward, driving the upper end of the power chain 28 to move backward. The one-way transmission sprocket 29 rotates backward, the transmission shaft 30 and the wire feeding gear 24 do not rotate, and the wire feeding chain 25 and the limit plate 26 do not move.

[0073] Fifth step, the front end of the push plate swings downward, and the limit slot locks the corrugated wire.

[0074] The lifting cylinder 16 drives the front end of the push plate 14 to swing downward, so that the bent corrugated wire is located in the limiting groove 15 at the lower end of the push plate 14.

[0075] Step 6: Move the wavy silk forward.

[0076] The first motor 10 drives the lead screw 11 to rotate, causing the wire bending and pushing frame 8 to move forward, which in turn drives the push plate 14 and the corrugated wire in the limiting slot 15 of the push plate 14 to move forward. The chain push-pull rod 27 in front of the wire bending and pushing frame 8 moves forward, which drives the upper end of the power chain 28 to move forward. The one-way transmission sprocket 29 drives the transmission shaft 30 and the wire feeding gear 24 to rotate, which drives the wire feeding chain 25, the limiting plate 26 and the corrugated wire to move forward.

[0077] The corrugated wire in the limiting slot 15 moves forward along the pusher plate 14, and the front end of the corrugated wire hits the rear end of the limiting spring 20, causing the limiting spring 20 to move upward and the corrugated wire to be stuck in the temporary limiting slot 21 at the lower end of the limiting spring 20.

[0078] The chain push rod 27 in front of the wire folding and pushing frame 7 moves forward, driving the upper end of the power chain 28 to move forward. The one-way transmission sprocket 29 drives the transmission shaft 30 and the wire feeding gear 24 to rotate, driving the wire feeding chain 25 and the limiting plate 26 to move forward. The wavy wire in the temporary limiting groove 21 at the front enters between the adjacent limiting plates 26 of the chain and is pushed forward by the limiting plate 26 behind. The wavy wire in the temporary limiting groove 21 pushes the limiting spring 20 forward. The lower end of the limiting spring 20 swings forward and upward, causing the wavy wire in the temporary limiting groove 21 to move forward out of the temporary limiting groove 21. The limiting spring returns to its original position under its own elastic force, and the next wavy wire enters the temporary limiting groove 21 from the rear.

[0079] Step 7: Repeat steps 2 through 6. The bent wavy wire is fed to the welding head position by the limiting plate 26 of the wire feeding chain 25 and welded to the longitudinal wire to form a mesh.
