Description

Technical Field

[0001] This invention relates to the field of welding wire production, specifically to a fully automated high-speed submerged arc welding production line and production method. Background Technology

[0002] Submerged arc welding requires multiple processes, and any one of these processes affects the final quality of the welding wire. With industrial progress, there are higher requirements for the speed, quality, and cost of welding wire production. Existing production methods can no longer meet the needs of fast, high-quality, and low-cost welding wire production.

[0003] In the existing technology, after the welding wire is drawn, a lot of dust adheres to the surface of the welding wire, which has an adverse effect on the subsequent copper plating process and affects the production quality of the welding wire. The existing dust removal method generally uses water rinsing, but since the welding wire is a thin strip, water rinsing has the problem of incomplete cleaning.

[0004] Thoroughly cleaning the welding wire to ensure it enters subsequent processes is essential for improving welding wire production quality and reducing welding wire loss rate. Summary of the Invention

[0005] In order to solve one or more technical problems in the prior art, or at least provide a beneficial alternative, the present invention provides a fully automated high-speed submerged arc welding production line, which solves the problems of low single-shift output and high cost in the welding wire production process, while improving the quality of welding wire production.

[0006] This invention discloses a fully automated high-speed submerged arc welding production line. The technical solution of this application includes processing equipment and cleaning equipment. The processing equipment includes a wire feeding frame, a belt sander, a dry wiping machine, a wire drawing machine, a copper plating device, and a wire take-up device. The cleaning equipment includes a welding wire cleaning device, a neutralizing water washing machine, a dryer, and an air cooler. The welding wire cleaning device is located between the wire drawing machine and the copper plating device. A submerged arc tension box is provided between the wire drawing machine and the welding wire cleaning device. The welding wire cleaning device includes a dry wiping section, a water washing section, and an air blowing section. The dry wiping section is equipped with a ball-shaped steel wire scrubber. The water washing section is equipped with a water washing pipeline connected to an external pressure pump. The water washing pipeline includes a water inlet pipe and a sewage outlet pipe. The air blowing section is equipped with an airflow passage connected to an external high-pressure air pump.

[0007] Welding wire production involves multiple processes, including rust removal and copper plating, while ensuring the wire remains clean after processing. Each step affects the final quality of the welded wire. This invention optimizes the welding wire production process by combining independently developed technology with existing techniques, thereby improving the quality of welded wire. The welding wire cleaning device in this invention not only washes the drawn wire with water but also first dry-wipes it to remove surface dust, then washes it with water to remove floating debris, and finally blows it with air to keep it dry. A clump of steel wire is used for dry wiping, providing strong cleaning power. Secondly, the clustered design can reach all sides and the bottom of the welding wire, thus providing a comprehensive cleaning. The water washing section includes an inlet pipe and a drain pipe. The inlet pipe is mainly used to rinse the welding wire and the clustered steel wire wipes with clean water, ensuring the cleanliness of both the welding wire and the steel wire wipes. This washes away any dust or other debris adhering to the steel wire wipes, preventing any impact on subsequent welding wire cleaning. The drain pipe is mainly used to discharge the used high-temperature, high-pressure water. The air blowing section dries the cleaned and wiped welding wire, ensuring it is clean and dry before proceeding to the next process.

[0008] In a preferred implementation of a fully automated high-speed submerged arc production line, the water washing section is equipped with a drain outlet, through which water from both the inlet pipe and the outlet pipe is discharged.

[0009] The water in the inlet pipe is used to clean the welding wire and wire scoop, while the water in the drain pipe is recycled high-temperature, high-pressure water, i.e., wastewater. A drain outlet is installed in the washing section, which can be located under the welding wire or wire scoop. The outlet of the drain pipe is located above the drain outlet. In this way, the cleaning water and collected wastewater are discharged through a single drain outlet, simplifying the water flow pipeline without affecting the sewage discharge effect.

[0010] In a preferred implementation of a fully automated high-speed submerged arc production line, the water washing section is equipped with a return water pipe, which includes a first return water pipe connected to the inlet water pipe and a second return water pipe connected to the drain pipe.

[0011] The main function of the return water pipe is to collect high-temperature and high-pressure water for return. The first return water pipe, connected to the inlet water pipe, collects clean high-temperature water, which is then reintroduced into the washing device through the inlet water pipe to rinse the welding wire and steel wire scoop before being discharged through the drain outlet. The second return water pipe collects the high-temperature wastewater that has already been used, which flows through the second return water pipe into the sewage pipe and then to the drain outlet for discharge. This classification and utilization of high-temperature water saves resources.

[0012] In a preferred implementation of a fully automated high-speed submerged arc production line, the wire feeding frame includes guide wheels and wire rods wound around the guide wheels, with a hammering device on one side of the wire rods.

[0013] This invention adds a hammering device to the original wire feeding machine. By using the force of the rotating guide wheel, the hammering device regularly strikes the wire, causing the wire to vibrate. This prevents the wire from sticking, knotting, and tangling. Without adding extra power, it solves the problem of wire tangling that easily occurs when the wire feeding frame feeds the wire quickly, thereby greatly improving the wire feeding speed and the performance of the equipment.

[0014] In a preferred implementation of a fully automated high-speed submerged arc production line, the hammering device is equipped with shielding components on both sides. The rotation of the guide wheel drives the hammering device to swing within the range between the two shielding components. During the swinging process, it impacts the wire rod, and the wire feeding speed exceeds 3m / s.

[0015] The original wire feeding frame had a maximum feeding speed of 3 meters per second. However, the failure rate was very high after the speed was increased, which directly hindered the improvement of equipment performance. The hammering device is equipped with shielding parts on both sides to limit the swing range of the hammering device and prevent it from moving too far during the swing, which would affect the wire feeding or prevent the hammering of the wire rod. The intermittent hammering of the wire rod by the hammering device prevents the wire from getting tangled or sticking, so that the wire feeding process can be carried out in an orderly and smooth manner, reducing the failure after the equipment speed is increased, and increasing the wire feeding speed to more than 3 m / s.

[0016] In a preferred implementation of a fully automated high-speed submerged arc welding production line, a guide table is provided between the dry wiping machine and the wire drawing machine. The dry wiping machine has through holes on both sides for the welding wire to pass through, and a brush and a straightener are provided inside. The brush is detachably installed on the dry wiping machine.

[0017] Straight-line processing requires too much space and makes it inconvenient for staff to monitor and manage the equipment and production process. However, the welding wire needs to run continuously throughout the entire production process. Therefore, a guide table is set between the dry wiping machine and the wire drawing machine. The guide table turns and guides the welding wire. After the welding wire exits from the through hole of the dry wiping machine, it is guided by the guide table to ensure that the welding wire continues to enter the next process stably. In addition, existing dry wiping machines generally use a vibrating pump and steel wool for dry wiping. The vibrating pump is extremely noisy and the resonance can easily cause the weld to crack. The steel wool wears out too quickly and cannot guarantee complete cleaning. This invention uses a brush dry wiping with a straightener. The brush is low-cost and effective. It can be detachably installed on the dry wiping machine for easy cleaning and replacement, creating a cleaning machine that is powerless, noiseless, and low-wear.

[0018] In a preferred implementation of a fully automated high-speed submerged arc welding production line, the brush is a spiral brush, and the spiral center of the spiral brush forms a welding wire channel.

[0019] To ensure thorough and effective cleaning of the welding wire, the brush inside the dry wiping machine is a spiral brush. Due to its special shape, a welding wire channel is automatically formed at the center of the spiral. As the welding wire passes through the brush, the spiral brush performs a 360-degree dry wiping of the welding wire, removing residual iron oxide powder from the surface of the welding wire.

[0020] In a preferred implementation of a fully automated high-speed submerged arc production line, the guide table is provided with an arc-shaped guide plate and a steering guide wheel, with the steering guide wheel located on the arc-shaped guide plate.

[0021] As a guiding device for the turning of welding wire, the guide table must stably perform its guiding function. The arc-shaped guide plate occupies a small area and is more in line with the turning requirements of welding wire. The welding wire turns along the arc of the arc-shaped guide plate. If the guide plate is set to square, the turning angle of the welding wire is required, and it is easy for external wind or other factors to touch the corner of the guide plate, causing damage or jamming of the welding wire. By setting a turning guide wheel on the arc-shaped guide plate, the welding wire can smoothly complete the turning along the arc of the guide plate from the center of the guide wheel.

[0022] In a preferred implementation of a fully automated high-speed submerged arc production line, the neutralizing water washing machine is fixed to the side wall of the copper plating device and has a through hole aligned with the air cooler. The welding wire passes through the outside of the dryer and enters the air cooler from the neutralizing water washing machine.

[0023] This invention employs a self-developed neutralization washing machine, using a bipolar annular air blowing method to achieve high-speed production without impurities. Existing dryers use hot air generated by a hot air blower to dry the welding wire, but hot air blower drying requires a large area and is slow. This invention uses high-frequency heating drying, which can reach a speed of over 20 meters per second, thus improving production speed.

[0024] In a preferred implementation of a fully automated high-speed submerged arc welding production method, the following steps are included:

[0025] The S1 welding wire is quickly fed into the belt sander via the wire feeder. The dual belt sanders operate to remove rust. The welding wire moves at a speed of 4 m / s within the belt sander, and the rust removal is completed inside the belt sander.

[0026] S2 welding wire enters the dry wiping machine via a belt sander, where the dry wiping machine removes rust powder from the surface of the welding wire.

[0027] S3 welding wire enters the wire drawing machine via a dry wiping machine. The wire drawing machine uses a permanent magnet motor and completes the wire drawing process through direct drive of the permanent magnet motor and CNC technology.

[0028] S4 welding wire enters the welding wire cleaning device after being drawn by the wire drawing machine, and is subjected to dry wiping, cleaning and air blowing in sequence.

[0029] S5 welding wire enters the copper plating unit after the welding wire cleaning device to complete the copper plating process.

[0030] S6 welding wire enters the neutralization water washing machine after passing through the copper plating device to adjust the acidity and alkalinity;

[0031] After passing through a neutralization and washing machine, the S7 welding wire is sequentially fed into a dryer and an air cooler for linear high-frequency drying and air cooling.

[0032] After being cooled by an air cooler, the S8 welding wire enters the take-up device, where it is collected, completing the welding wire production process. Attached Figure Description

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0048] First, the technical concept of the technical solution disclosed in this invention will be explained. The production of welding wire requires multiple processes such as rust removal, drawing, and copper plating. Each step in the welding wire production process is crucial, and quality assurance is essential for each process. Existing welding wire production processes often suffer from long production times, low output, high labor costs, and high losses. To reduce welding wire production costs and improve welding wire quality, this invention provides a fully automated high-speed submerged arc welding production line and method. It improves processes such as wire feeding, rust removal, wire drawing, copper plating, and cleaning, increasing single-shift output, reducing labor costs, decreasing welding wire losses, and improving welding wire quality.

[0049] The specific solution adopted is as follows: Figure 1-5 As shown, a fully automated high-speed submerged arc welding production line includes: processing equipment and cleaning equipment; the processing equipment includes a wire feeding frame 1, a belt sander 2, a dry wiping machine 3, a wire drawing machine 4, a copper plating device 6, and a wire take-up device 10; the cleaning equipment includes a welding wire cleaning device 5, a neutralizing water washing machine 7, a dryer 8, and an air cooler 9; the welding wire cleaning device 5 is located between the wire drawing machine 4 and the copper plating device 6, and a submerged arc tension box 12 is provided between the wire drawing machine 4 and the welding wire cleaning device 5; the welding wire cleaning device 5 includes a dry wiping section, a water washing section, and an air blowing section; the dry wiping section is equipped with a ball-shaped steel wire rubber 501; the water washing section is equipped with a water washing pipeline connected to an external pressure pump; the water washing pipeline includes a water inlet pipe 502 and a sewage outlet pipe 503; the air blowing section is equipped with an airflow passage 505 connected to an external high-pressure air pump.

[0050] In one embodiment, the raw material wire rod is released from the wire feeder 1 and passes sequentially through the belt sander 2 and the dry rubbing machine 3. A guide table 11 is provided between the dry rubbing machine 3 and the wire drawing machine 4. After being turned by the guide table 11, the welding wire enters the wire drawing machine 4, and then sequentially enters the welding wire cleaning device 5 and the copper plating device 6. A neutralizing water washing machine 7 is fixed to the side wall of the copper plating device 6. After copper plating, the welding wire enters the neutralizing water washing machine 7. After cleaning, it undergoes high-frequency drying. After drying, it is cooled by air cooling. After cooling, it is taken up by the take-up device 10. The wire feeder 1 includes a guide wheel 102 and a wire rod wound around the guide wheel 102. A hammering device 101 is provided on one side of the wire rod, and shielding members 103 are provided on both sides of the hammering device 101. The guide wheel 102 rotates, causing the hammering device 101 to swing within the range between the two blocking members 103. During the swing, it impacts the wire rod. The blocking member 103 can be configured as a positioning member with protrusions. The hammering device 101 moves between the two protrusions. The blocking member 103 limits the swing range of the hammering device 101, preventing the hammering device 101 from moving too far during the swing, affecting the wire feeding or failing to hammer the wire rod. The wire feeding speed exceeds 3m / s. The force of the guide wheel rotation drives the hammering device 101 to regularly strike the wire, causing the wire to vibrate. This avoids wire sticking, buckling, and tangling. Without adding extra power, it solves the problem of tangling that easily occurs when the wire feeding frame 1 feeds wire quickly, and improves the wire feeding speed.

[0051] In one embodiment, two belt sanders 2 are configured to work simultaneously. Digital control technology is used to control both belt sanders 2 to evenly remove rust from the welding wire. This reduces the intensity of a single belt sander 2 while improving the rust removal effect, allowing for stable production at a speed of 4 meters per second. After rust removal, the welding wire enters the dry wiping machine 3 via the belt sander 2. Since the vibration pump is extremely noisy and resonance can easily cause weld cracking, and steel wool breaks down too quickly, failing to guarantee complete cleaning, this embodiment avoids the traditional vibration pump and steel wool dry wiping mode. Instead, it uses a brush 301 with a straightener. The brush 301 has a longer service life than steel wool and also has the advantages of low cost and good effect. A brush 301 mounting part is provided in the dry wiping machine 3, and the brush 301 is detachably installed using snap-fit ​​or bolt fixing methods, facilitating cleaning and replacement of the brush 301, creating a power-free, noise-free, and low-wear cleaning machine.

[0052] In one embodiment, to ensure the cleaning power and thoroughness of the welding wire, the brush 301 inside the dry wiping machine 3 is set as a spiral brush. Due to its special shape, the spiral center of the brush automatically forms a welding wire channel. As the welding wire passes through the brush 301, the spiral brush performs a 360-degree dry wiping, removing residual iron oxide powder from the surface of the welding wire. After dry wiping, the welding wire enters the wire drawing machine 4. A straight-line process requires too much space and is inconvenient for staff to monitor and manage the equipment and production process. However, the welding wire needs to pass through the entire production process without interruption. Therefore, a guide table 11 is set between the dry wiping machine 3 and the wire drawing machine 4. The guide table 11 guides and deflects the welding wire. Through holes are provided on both sides of the dry wiping machine 3 for the welding wire to pass through. After the wire exits through the through hole, it is guided by the guide table 11 to change direction, ensuring that the welding wire continues to enter the wire drawing machine 4 stably. The guide table 11 is equipped with an arc-shaped guide plate 111 and a turning guide wheel 112. The turning guide wheel 112 is located on the arc-shaped guide plate 111. As a guiding device for the turning of the welding wire, the guide table 11 must stably play a guiding role. The arc-shaped guide plate 111 occupies a small area and is more in line with the turning requirements of the welding wire. The welding wire turns along the arc of the arc-shaped guide plate 111. If the guide plate 111 is set as a square, the turning of the welding wire requires a larger angle, and it is easy to touch the corner of the guide plate 111 due to external wind or other factors, causing damage or jamming of the welding wire. The turning guide wheel 112 is set on the arc-shaped guide plate 111, and the welding wire smoothly completes the turning along the arc of the guide plate 111 from the center of the guide wheel 102. Most wire drawing machines 4 use motor belt drive to drive a reducer, which in turn drives the wire drawing can. This results in high power consumption, unstable transmission, and a high wire breakage rate. To reduce maintenance costs and lower the failure rate, this embodiment uses a permanent magnet motor to directly drive the wire drawing machine 4. It features digital control for automatic balancing, fast wire drawing speed, low machine failure rate, and is more energy-efficient than using a belt drive.

[0053] In one embodiment, the surface of the welding wire after being processed by the wire drawing machine 4 often has floating sediment, which easily leads to impurities being added during subsequent copper plating. A welding wire cleaning device 5 is installed between the wire drawing machine 4 and the copper plating device 6, and a submerged arc tension box 12 is installed between the wire drawing machine 4 and the welding wire cleaning device 5. The welding wire cleaning device 5 includes a dry wiping section, a water washing section, and an air blowing section. The dry wiping section is equipped with a ball-shaped steel wire scrubber 501. The water washing section is equipped with a water washing pipeline connected to an external pressure pump. The water washing pipeline includes a water inlet pipe 502, a drain pipe 503, a drain outlet 504, and a return water pipe. The return water pipe further includes a first return water pipe connected to the water inlet pipe 502 and a return water pipe connected to the drain pipe 503. The second return water pipe is connected to the inlet pipe 502; the water in the inlet pipe 502 is used to clean the welding wire and wire rubber 501, and the water in the drain pipe 503 is used high-temperature and high-pressure water. The drain outlet 504 can be set under the welding wire or wire rubber 501, and the outlet of the drain pipe 503 is set above the drain outlet 504. In this way, the cleaning water and collected wastewater are discharged through a single drain outlet 504, which simplifies the water flow pipeline without affecting the sewage discharge effect. The first return water pipe connected to the inlet pipe 502 is used to collect clean high-temperature water, which re-enters the water washing device through the inlet pipe 502 to clean the welding wire and wire rubber 501. After rinsing, the wastewater is discharged through drain outlet 504. The second return water pipe collects the utilized high-temperature wastewater, which then flows into the sewage pipe 503 and out through the sewage pipe 504. The high-temperature water is classified and utilized to save resources. The air blowing section is equipped with an airflow passage 505 connected to an external high-pressure air pump. After wire drawing, the welding wire is not only washed with water, but also first dry-wiped to remove surface dust, then washed with water to remove floating dust, and finally air-blown to keep the welding wire dry. The clump-shaped steel wire wiper 501 dry-wipes the welding wire, which has strong cleaning power and the clump shape can take care of the surface. The welding wire is wiped from all sides and bottom. The water washing section includes an inlet pipe 502 and a drain pipe 503. The inlet pipe 502 is mainly used to rinse the welding wire and the clump of steel wire 501 with clean water, ensuring the cleanliness of both the welding wire and the steel wire 501. This washes away dust and other debris adhering to the steel wire 501, preventing it from affecting subsequent welding wire wiping. The drain pipe 503 is mainly used to discharge the used high-temperature and high-pressure water. The air blowing section dries the wiped and cleaned welding wire, ensuring it is clean and dry before proceeding to the next process.

[0054] In one embodiment, copper plating of the welding wire is carried out using electroplating or chemical copper plating processes. A neutralizing water washing machine 7 is fixed to the side wall of the copper plating device 6. The neutralizing water washing machine 7 has through holes for the welding wire to pass through and adopts a bipolar annular air blowing method to achieve high-speed production without impurities. An air cooler 9 is arranged opposite to the neutralizing water washing machine 7. A dryer 8 is arranged between the air cooler 9 and the neutralizing water washing machine. The welding wire passes through the outside of the dryer 8 and enters the air cooler 9. The speed of the dryer 8 can reach more than 20m / s. After the welding wire is dried by high-frequency heating in the dryer 8, it is cooled by air cooling in the air cooler 9 to stabilize the shape of the welding wire. Then it is completely retracted by the take-up device 10.

[0055] The technical solutions protected by this invention are not limited to the above embodiments. It should be noted that any combination of the technical solutions of any embodiment with one or more other embodiments is within the protection scope of this invention. Although the invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this invention are within the scope of protection claimed by this invention.

S5 welding wire enters the copper plating unit through the welding wire cleaning device to complete the copper plating process; S6 welding wire enters the neutralization water washing machine through the copper plating device to adjust the acidity and alkalinity; After passing through the neutralization and washing machine, the S7 welding wire enters the dryer and air cooler in sequence to perform linear high-frequency drying and air cooling. The S8 welding wire is cooled by air and then enters the take-up device, where it is collected to complete the welding wire production process.
