Description

Technical Field

[0001] The present invention belongs to the technical field of welding equipment, and more specifically, particularly relates to a continuous welding equipment for processing arch foot steel bar mesh sheets. Background Art

[0002] Steel bar mesh sheet welding and processing equipment is a mechanical device specifically used to connect steel bars into a mesh-like structure through welding methods such as resistance welding and arc welding. In practical applications, continuous welding equipment usually requires the following technologies: Welding mechanism, which generates high temperature at the intersection of steel bars through current; Feeding mechanism, which accurately conveys the steel bars to the welding position; Body structure, which supports and fixes each component of the equipment; Control system, which controls the welding current and feeding speed of the welding equipment; First, straighten the steel bars to ensure that the steel bars remain straight before entering the welding area, accurately convey the steel bars to the welding position, provide a low-voltage and high-current power supply required for welding, generate high temperature at the intersection of steel bars through current, melt the steel bars locally and connect them together. However, during welding, there are the following deficiencies; Soft steel bars are prone to deformation when subjected to external forces. During the feeding process, if the traction force is uneven or there is friction with other components, the steel bars may bend or twist, resulting in deviation, inaccurate welding point positions, and affecting the welding progress.

[0003] The welded steel bar mesh sheet moves through the conveyor belt, and the welding points can only be cooled naturally, resulting in a slow cooling speed. At the same time, long-term continuous welding is likely to cause electrode wear, resulting in insecure welding points. During subsequent transportation, it cannot be quickly detected, which will affect the welding and processing quality of the steel bar mesh sheet. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a continuous welding equipment for processing arch foot steel bar mesh sheets to solve the above problems.

[0005] A continuous welding equipment for processing arch foot steel bar mesh sheets includes a double-bar feeding base, a steel bar body, and a support base. A frame body for installation and positioning is slidably installed at the top end of the steel bar body. An arc-shaped conveying plate for conducting steel bars is fixedly installed at the side end of each support base. A plurality of welding components are slidably installed at the side end of the frame body. Each welding component includes a driver, a welding tube, a telescopic tube sleeve, and a steel bar locking cylinder. A cooling component is fixedly installed on the surface of each welding tube. Each cooling component includes a fixed sleeve, a heat dissipation tube, an air guiding hose, and a detection frame; Each of the heat dissipation tubes is equidistantly distributed inside the fixed sleeve. The inside of each heat dissipation tube is designed to be hollow and is connected to the air guiding hose in a through manner. The arc-shaped conveying plate is designed to be curved and is hollow inside. At the same time, a positioning groove is provided at the bottom end of each steel bar locking cylinder.

[0006] Preferably, a sliding connection seat for vertical movement is slidably installed inside each detection frame. A positioning frame for butt joint and clamping is fixedly installed at the top end of each sliding connection seat. An elastic sleeve rod that can be telescoped is fixedly installed at the top end of each sliding connection seat. A contact plate for sliding friction is fixedly installed inside each detection frame. An air vent hose for connection and limit is fixedly installed inside each positioning frame. Friction plates are slidably installed on the two inner side walls of each positioning frame. An expandable sleeve that can be telescoped is fixedly installed at the end of each friction plate. Support arms are slidably installed at both side ends of each sliding connection seat. A sliding positioning rod inserted into a rotating shaft is fixedly installed at the side end of each support arm. A telescopic pull rod for butt joint installation is fixedly installed at the side end of each sliding positioning rod.

[0007] Preferably, a guiding wheel that can rotate synchronously is rotatably installed at the end of each support arm. A double-end compression rod that can slide and expand is fixedly installed at the side ends of the two guiding wheels. At least two directional nozzles recessed inward are provided on the surface of each guiding wheel. An air control disc that rotates synchronously is fixedly installed at the side end of each guiding wheel. A sealing sleeve is fixedly installed inside each support arm. Multiple top-end storage air bags are fixedly installed inside each sealing sleeve. The top end of each storage air bag is designed to be hemispherical.

[0008] Preferably, a guide rail carriage for butt joint with the frame body is fixedly installed at the top end of each driver. Two bolts for vertical rotation are rotatably installed at the top end of each guide rail carriage. Warning light strips are fixedly installed at both side ends of each driver. Each warning light strip is connected to the support base through a wire harness. Two hydraulic rods are fixedly installed at the bottom end of the frame body. The end of the frame body is in butt joint and sliding connection with the top end of the support base.

[0009] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, the acting force generated by the downward telescopic movement of two elastic sleeve rods always exerts a downward thrust on the sliding connection seat, causing it to slide downward inside the detection frame. The sliding connection seat drives two support arms to move downward, enabling two guide wheels to respectively fit onto the surface of the steel bar body. The guide wheels are symmetrically conical in design and can be clamped onto the surface of the steel bar body, guiding the movement of the steel bar body and preventing it from deviating when moving.

[0010] In the present invention, by making the positioning frame dock and slide with the contact plate, two friction plates are slidably installed inside the positioning frame, and two metal sheets are provided on both sides of the contact plate. When the welding end is firm, the sliding connection seat can slide upward. When the welding is not firm, the guide wheel presses against the welding end, causing the two steel bar bodies to bend and separate. Restricted by the pressure exerted by the elastic sleeve rod, the distance that the sliding connection seat can move is limited. The metal sheets on both sides of the contact plate do not dock with the friction plates, and the warning light bars on both sides of the sensor driver will flash to remind the staff that there is a break in the welding.

[0011] In the present invention, the end of the welding pipe squeezes and expands with the telescopic pipe sleeve. The top of the telescopic pipe sleeve is compressed, and the end of the welding pipe moves downward to fit the welding end of the steel bar body. High temperature is generated at the intersection of the steel bars through the current, causing the steel bars to locally melt and be connected together. Two steel bar locking cylinders first pre-fix the two groups of steel bar bodies. Pre-compression can ensure that the steel bar bodies do not move during the welding process, and at the same time increase the contact pressure between the steel bar bodies. During the welding process, sufficient contact pressure can ensure that the current can pass smoothly through the welding area, improving the welding efficiency and quality.

[0012] In the present invention, by making the support arm slide at the side end of the sliding connection seat, a sliding positioning rod is installed at the side end of the support arm. The sliding positioning rod is rectangular in design and is slidably connected to the fixed shaft. At the same time, a telescopic pull rod is installed at the end of the sliding positioning rod, applying a pulling force in the opposite direction to the sliding positioning rod, causing the support arm to drive the welding pipe to fixedly clamp the surface of the steel bar body. By the horizontal sliding of the support arm and the guide wheel, the distance between the guide wheels can be adjusted to guide steel bar bodies of different sizes, increasing the flexibility of use.

[0013] In the present invention, the side end of the air storage bag is rotatably connected to the air control disc. The surface of the sealing sleeve is provided with drainage holes, and the side end of the air storage bag is also provided with drainage holes. The guide wheel drives the guide wheel to rotate, causing the air control disc to rotate at the side end of the air storage bag, allowing cold air to continuously enter the inside of the guide wheel intermittently and then spray out through the directional nozzles on the surface, rapidly cooling the welded steel bar body, quickly removing some heat, and preventing the welding area from overheating.

[0014] In the present invention, a long strip-shaped guide rail is provided at the side end of the frame body. By rotating the bolt at the top of the guide rail carriage, the bolt is disengaged from the top of the guide rail carriage, and the fixation of the driver is released. By pushing the driver to slide at the side end of the frame body, the position of the driver can be adjusted individually. The welding points can be adjusted according to different steel bar meshes to be processed. At the same time, the driver can also be pulled to slide at the side end of the frame body to disassemble the driver. Through the modular design, it is convenient for later maintenance and replacement. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION

[0017] The following further describes in detail the embodiments of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0018] Please refer to Figure 1 - Figure 10 , the present invention provides a continuous welding device for processing the arch foot steel mesh, including a double-rib conveying base 11, a steel bar body 12 and a support base 13. A frame body 14 for positioning installation is slidably installed at the top end of the steel bar body 12. An arc-shaped conveying plate 15 for conducting steel bars is fixedly installed at the side end of each support base 13. A plurality of welding components are slidably installed at the side end of the frame body 14. Each welding component includes a driver 16, a welding pipe 17, a telescopic pipe sleeve 18, and a steel bar locking cylinder 19. The arc-shaped conveying plate 15 is of a curved design and is hollow inside. At the same time, a positioning groove is provided at the bottom end of each steel bar locking cylinder 19. During the downward movement of the welding pipe 17, the steel bar locking cylinder 19 presses and rubs against the surface of the steel bar body 12. At the same time, the steel bar locking cylinder 19 is provided with symmetric grooves in two perpendicular directions to respectively press and position the steel bar body 12. At the same time, the welding pipe 17 continues to press, and the end of the welding pipe 17 squeezes and expands the telescopic pipe sleeve 18. The top end of the telescopic pipe sleeve 18 is compressed, and the end of the welding pipe 17 moves downward to fit the welding end of the steel bar body 12. High temperature is generated at the intersection of the steel bars through current, causing the steel bars to locally melt and be connected together. The two steel bar locking cylinders 19 first pre-fix the two groups of steel bar bodies 12; A cooling component is fixedly installed on the surface of each welding pipe 17. Each cooling component includes a fixed sleeve 21, a heat dissipation pipe 22, an air guiding hose 23, and a detection frame 24. Each heat dissipation pipe 22 is equidistantly distributed inside the fixed sleeve 21. The inside of each heat dissipation pipe 22 is of a hollow design and is connected to the air guiding hose 23 in a through manner. Cooling air is introduced into the inside of the fixed sleeve 21 through an interface. During each welding, the air flow flows inside the heat dissipation pipe 22 to continuously cool the inside of the welding pipe 17 and ensure the service life of the components; Inside each detection frame 24, a sliding connection seat 25 for vertical movement is slidably installed. At the top of each sliding connection seat 25, a positioning frame 34 for butt-joint positioning is fixedly installed. At the top of each sliding connection seat 25, a telescopic elastic sleeve rod 39 is fixedly installed. Inside each detection frame 24, a contact plate 38 for sliding friction is fixedly installed. When the welding end is firm, the sliding connection seat 25 can slide upward. When the welding is not firm, the guide wheel 27 presses the welding end, which will cause the two steel bar bodies 12 to bend and separate. Restricted by the pressure exerted by the elastic sleeve rod 39, the distance that the sliding connection seat 25 can move is limited. The metal sheets on both sides of the contact plate 38 are not butt-jointed with the friction plate 37, and the warning light strips 43 on both sides of the trigger sensor driver 16 will flash to remind the staff. Inside each positioning frame 34, an air vent hose 35 for connection and limitation is fixedly installed. On both inner side walls of each positioning frame 34, a friction plate 37 is slidably installed. At the end of each friction plate 37, a telescopic expansion sleeve 36 is fixedly installed; On both side ends of each sliding connection seat 25, a support arm 26 is slidably installed. At the side end of each support arm 26, a sliding positioning rod 41 inserted into the rotating shaft is fixedly installed. At the side end of each sliding positioning rod 41, a telescopic pull rod 42 for butt-joint installation is fixedly installed. Let the support arm 26 slide at the side end of the sliding connection seat 25. A sliding positioning rod 41 is installed at the side end of the support arm 26. The sliding positioning rod 41 is rectangular in design and is slidably connected to the fixed shaft. At the same time, a telescopic pull rod 42 is installed at the end of the sliding positioning rod 41. Pull the sliding positioning rod 41 in the reverse direction to apply a pulling force, so that the support arm 26 drives the welding pipe 17 to fixedly clamp the surface of the steel bar body 12. By the horizontal sliding of the support arm 26 and the guide wheel 27, the distance of the guide wheel 27 can be adjusted; At the end of each support arm 26, a guide wheel 27 that can rotate synchronously is rotatably installed. At the side ends of the two guide wheels 27, a double-end compression rod 28 that slides and expands is fixedly installed. On the surface of each guide wheel 27, at least two directional nozzles 29 that are recessed inward are provided. At the side ends of each guide wheel 27, a gas control disc 31 that rotates synchronously is fixedly installed. Inside each support arm 26, a sealing sleeve 32 is fixedly installed. Inside each sealing sleeve 32, multiple top air storage bags 33 are fixedly installed. The top of each air storage bag 33 is designed to be hemispherical. Cold air enters the inside of the air storage bag 33. One side of the air storage bag 33 is hemispherical in design. The air storage bag 33 as a whole is made of expandable rubber material. The side end of the air storage bag 33 is installed and sleeved inside the sealing sleeve 32. The side end of the air storage bag 33 is rotatably connected to the gas control disc 31. A drain hole is installed on the surface of the sealing sleeve 32. At the same time, a drain hole is also installed at the side end of the air storage bag 33. The guide wheel 27 drives the guide wheel 27 to rotate, causing the gas control disc 31 to rotate at the side end of the air storage bag 33, allowing cold air to continuously enter the inside of the guide wheel 27 intermittently and then be ejected through the directional nozzles 29 on the surface; At the top of each driver 16, a guide rail carriage 44 docked with the frame body 14 is fixedly installed. At the top of each guide rail carriage 44, two bolts for vertical rotation are rotatably installed. At the two side ends of each driver 16, a warning light strip 43 is fixedly installed. Each warning light strip 43 is connected to the support base 13 through a wire harness. At the bottom end of the frame body 14, two hydraulic rods 45 are fixedly installed. The end of the frame body 14 is docked and slides with the top of the support base 13.

[0019] Working principle: First step, an electric motor and a transformer are installed inside the double-rib conveying base 11. At the same time, a power cord is connected to the side end of the double-rib conveying base 11 and the support base 13. Multiple groups of steel bar bodies 12 are arranged and placed on the surface of the double-rib conveying base 11. At the same time, another group of steel bar bodies 12 is placed inside the arc-shaped conveying plate 15. The inside of the arc-shaped conveying plate 15 is hollow, and the inside of the arc-shaped conveying plate 15 is designed to be curved, which can transfer two groups of steel bar bodies 12 for assembly. Then, by driving the hydraulic rod 45 to expand and contract, the steel bar body 12 slides downward at the top of the support base 13, driving the welding pipe 17 to weld the intersection of the two groups of steel bar bodies 12. A telescopic pipe sleeve 18 and a steel bar locking cylinder 19 are installed at the bottom end of the welding pipe 17. The upper half of the telescopic pipe sleeve 18 is a multi-section telescopic structure, which is aligned with the bottom end of the welding pipe 17. During the downward movement of the welding pipe 17, the steel bar locking cylinder 19 presses and rubs against the surface of the steel bar body 12 downward. At the same time, the steel bar locking cylinder 19 is provided with symmetric grooves in two perpendicular directions to respectively press and position the steel bar body 12. At the same time, the welding pipe 17 continues to press. The end of the welding pipe 17 squeezes and expands the telescopic pipe sleeve 18. The top end of the telescopic pipe sleeve 18 is compressed, and the end of the welding pipe 17 moves downward to fit the welding end of the steel bar body 12. High temperature is generated at the intersection of the steel bars through the current, causing the steel bars to locally melt and be connected together. The two steel bar locking cylinders 19 first pre-fix the two groups of steel bar bodies 12. Pre-compression can ensure that the steel bar body 12 does not move during the welding process, and at the same time increase the contact pressure between the steel bar bodies 12. During the welding process, sufficient contact pressure can ensure that the current can smoothly pass through the welding part, improving the welding efficiency and quality.

[0020] Meanwhile, the welding pipe 17 moves downward, driving the fixed sleeve 21 to move together. Inside the fixed sleeve 21, there are multiple heat dissipation pipes 22 installed. The heat dissipation pipes 22 are equidistantly distributed inside the fixed sleeve 21. At the same time, two air guide hoses 23 are installed at the top of the fixed sleeve 21. On the outside of the fixed sleeve 21, a detection frame 24 is fixedly installed. The top of the detection frame 24 is connected to the driver 16 at the same time. At the top of the driver 16, there is a pipe interface. Through the interface, the cooling air is introduced into the inside of the fixed sleeve 21. During each welding, the air flows inside the heat dissipation pipes 22 to continuously cool the inside of the welding pipe 17, ensuring the service life of the components. At the same time, a sliding connection seat 25 is slidably installed inside the detection frame 24. Fixed shafts are rotatably installed at both side ends of the sliding connection seat 25. The side end of the support arm 26 is connected to the fixed shaft. At the same time, two elastic sleeve rods 39 are installed at the top of the sliding connection seat 25. Through the downward telescopic force generated by the two elastic sleeve rods 39, a downward thrust is always applied to the sliding connection seat 25, causing it to slide downward inside the detection frame 24. The sliding connection seat 25 drives the two support arms 26 to move downward, so that the two guide wheels 27 are respectively in contact with the surface of the steel bar body 12. The guide wheels 27 are symmetrically conical in design and can be clamped on the surface of the steel bar body 12 to guide the movement of the steel bar body 12 and prevent the steel bar body 12 from deviating when moving.

[0021] Meanwhile, a double-end compression rod 28 is installed between the two guide wheels 27. The two ends of the double-end compression rod 28 are respectively connected to the guide wheels 27. At the same time, the double-end compression rod 28 is a multi-section telescopic structure. For steel bar bodies 12 of different sizes, the support arm 26 pushes the guide wheel 27 downward to align and contact the surface of the steel bar body 12. The guide wheel 27 is forced to slide horizontally to both sides, increasing the distance between the guide wheels 27. At the same time, the guide wheel 27 applies a force to the support arm 26, causing the support arm 26 to slide at the side end of the sliding connection seat 25. A sliding positioning rod 41 is installed at the side end of the support arm 26. The sliding positioning rod 41 is rectangular in design and is slidably connected to the fixed shaft. At the same time, a telescopic pull rod 42 is installed at the end of the sliding positioning rod 41, applying a reverse pulling force to the sliding positioning rod 41, causing the support arm 26 to drive the welding pipe 17 to fixedly clamp the surface of the steel bar body 12. Through the horizontal sliding of the support arm 26 and the guide wheel 27, the distance between the guide wheels 27 can be adjusted to guide steel bar bodies 12 of different sizes, increasing the flexibility of use.

[0022] Second step, the movement of the steel bar body 12 frictions with the guide wheel 27, driving the guide wheel 27 to rotate at the side end of the support arm 26. At the same time, a plurality of directional nozzles 29 are arranged on the surface of the guide wheel 27. The directional nozzles 29 are arranged at the outermost side of the outer surface of the guide wheel 27 to avoid frictions with the steel bar body 12. At the same time, an air diversion hose 23 is connected to the detection frame 24 through a branch. An air vent hose 35 is installed at the top of the sliding connection seat 25. The inside of the air vent hose 35 is hollow, and both ends of the air vent hose 35 can be telescoped. At the same time, the air vent hose 35 transmits the cold air inside the air diversion hose 23 to the sliding connection seat 25. The sliding connection seat 25 transmits the cold air to the support arm 26 through the inner pipeline. An interface is installed at the top of the air storage bag 33. The interface is docked with the pipeline, and the cold air enters the inside of the air storage bag 33. One side of the air storage bag 33 is designed as a hemisphere. The air storage bag 33 as a whole is made of expandable rubber material. The side end of the air storage bag 33 is installed and sleeved inside the sealing sleeve 32. The side end of the air storage bag 33 is rotatably connected to the air control disc 31. Drain holes are arranged on the surface of the sealing sleeve 32. At the same time, drain holes are also arranged at the side end of the air storage bag 33. The guide wheel 27 drives the guide wheel 27 to rotate, causing the air control disc 31 to rotate at the side end of the air storage bag 33, allowing the cold air to continuously and intermittently enter the inside of the guide wheel 27 and spray out through the directional nozzles 29 on the surface, quickly cooling the welded steel bar body 12, quickly taking away part of the heat, and preventing the welding area from overheating.

[0023] The continuously rotating conveyor belt drives the steel bar body 12 to move, causing the two guide wheels 27 to rotate on the surface of the steel bar body 12. The rotating guide wheels 27 squeeze and collide with the welding ends of the two steel bar bodies 12. The guide wheels 27 are subject to resistance and move upward. The guide wheels 27 friction with the welding ends, and the guide wheels 27 drive the support arms 26 to rotate at the side ends of the sliding connection seats 25. Since the guide wheels 27 can rotate by themselves and the support arms 26 are inclinedly installed, when the guide wheels 27 touch the welding ends and move upward, they drive the sliding connection seats 25 to slide upward inside the detection frame 24, causing the positioning frame 34 to dock and slide with the contact position plate 38. Two friction plates 37 are slidably installed inside the positioning frame 34. Two metal sheets are arranged on both sides of the contact position plate 38. When the welding ends are firm, the sliding connection seats 25 can slide upward. When the welding is not firm, the guide wheels 27 squeeze the welding ends, which will cause the two steel bar bodies 12 to bend and separate. Subject to the pressure applied by the elastic sleeve rod 39, the moving distance of the sliding connection seats 25 is limited. The metal sheets on both sides of the contact position plate 38 do not dock with the friction plates 37, and the warning light strips 43 on both sides of the trigger sensor driver 16 will flash to remind the staff that there is a break in the welding.

[0024] A strip-shaped guide rail is provided at the side end of the frame body 14. By rotating the bolt at the top of the guide rail carriage 44 to make the bolt leave the top of the guide rail carriage 44, the fixation of the driver 16 is released. By pushing the driver 16 to slide at the side end of the frame body 14, the position of the driver 16 can be adjusted individually, the welding points can be adjusted according to different steel bar meshes to be processed. At the same time, the driver 16 can also be pulled to make the driver 16 slide at the side end of the frame body 14, and the driver 16 can be disassembled. Through the modular design, it is convenient for later maintenance and replacement.

Many modifications and variations are obvious to those of ordinary skill in the art.
