Description

Technical Field

[0001] The present invention relates to the technical field of steel coil welding, and in particular to a splicing welding device and method based on steel coil processing. Background Art

[0002] Steel coils are made by hot-rolling or cold-rolling steel strips to a specific thickness and width, which are then wound into coils. Steel coils are widely used. In some industrial production processes, such as automotive and home appliance manufacturing, long lengths of steel are required to manufacture components. However, the length of a single steel coil is often limited. Through splicing and welding, multiple coils can be connected to meet production length requirements.

[0003] In current industrial production, the degree of automation of steel coil welding equipment urgently needs to be improved. In the actual operation process, operators need to rely on their naked eyes and experience to accurately align the steel coils to be welded. This process not only requires extremely high operating precision, but also due to the heavy weight and sharp surface of the steel coils, the slightest carelessness can lead to scratches, extrusion and other safety accidents. Even after the docking is completed, during the welding process, humans still need to continue to support the steel coils by hand to ensure their stability. Long-term repetitive high-intensity work not only makes operators prone to fatigue, but also affects their working state. In addition, the welding process that relies on manual operation is subject to the limitations of personnel's operating speed and energy, making it difficult to achieve efficient and continuous large-scale production, becoming a key bottleneck restricting the increase in production capacity.

A first bevel gear is installed on the rotating shaft, and two coaxial second bevel gears are installed in the base. The bottom end of the second gear is connected to a third bevel gear through a safety clutch, and the two second bevel gears are respectively connected to the first bevel gear and the third bevel gear. When the moving wheel moves, the second gear is driven by the first bevel gear, the second bevel gear and the third bevel gear on the rotating shaft, thereby driving the guide splint to move; when the guide splint contacts the two ends of the material roll, the safety clutch comes into play.

[0017] Furthermore, when the feeding mechanism approaches the machine body, the guide column of the guide rod slides into the guide groove of the guide block, and the guide block is opened by the guiding action of the guide groove.

[0018] Furthermore, when the feeding mechanism is reset, the receiving plate is reset through the torsion spring. At this time, the receiving plate engages with the third rack through the third gear, so that the third rack pulls the pull plate to reset through the pull wire.

[0019] Furthermore, the pressure wheel is used to press and flatten the steel coil, the disc electrode is used to roll weld the steel coil, and the scraper is used to scrape the cooling water sprayed from the cooling nozzle, collect it in the liquid collecting hopper, and then send it into the water tank through the conduit to realize cooling liquid circulation.

[0020] Furthermore, the cylinder drives the second sliding seat to descend, thereby lowering the welding mechanism, and the welding mechanism is inserted into the inner frame of the fixing mechanism through the guide side plate and the inclined surface of the mounting plate.

[0021] Furthermore, the steel coil is placed between the support roller and the pressure roller of the feeding mechanism, and the pressure roller is driven down by the hydraulic cylinder to clamp and fix the steel coil.

[0028] S5. The moving mechanism slides on the machine body through the slide rail, and the cylinder drives the second sliding seat to descend, causing the welding mechanism to descend;

[0029] S6. The welding mechanism is inserted into the inner frame of the fixing mechanism through the guide side plate and the inclined surface of the mounting plate, driving the inner frame to move within the outer frame, and the pressing wheel presses and flattens the steel coil;

[0030] S7, the disc electrode performs rolling welding on the steel coil, while the cooling nozzle sprays coolant to cool the welding part;

[0031] S8, the coolant is scraped off by the scraper, collected by the collecting hopper and then sent to the water tank through the conduit to realize the coolant circulation;

[0032] S9. When the feeding mechanism is reset, the receiving plate is reset by the torsion spring, and the third gear is engaged with the third rack, so that the third rack pulls the pulling plate to reset through the pull wire.

[0034] The support roller and pressure roller on the feeding mechanism are connected by a transmission mechanism, and the pressure roller can be adjusted to a certain extent to accommodate the feeding needs of steel coils of different thicknesses and materials. Guide plates are connected to the support roller and pressure roller to ensure that the steel coil maintains linear motion during feeding, ensuring accurate and stable feeding.

[0035] The welding mechanism is equipped with a disc electrode and a cooling nozzle. The disc electrode can provide stable and efficient welding energy, while the cooling nozzle can timely cool the welding area during the welding process, avoiding quality problems such as welding deformation and cracks caused by overheating, thereby improving the welding quality and the performance of the welded joint.

[0036] The fixing mechanism, through the cooperation of the outer and inner frames, secures the steel coil in place. The pressure roller applies pressure to the steel coil to prevent it from moving or shaking during welding. The scraper removes water stains and impurities from the steel coil surface, ensuring a clean weld surface and further improving weld quality.

[0037] The pull plate, receiving plate, third rack, and third gear of the limiter assembly work together to effectively limit the feed of the feed mechanism. If the feed mechanism deviates from its position, the limiter assembly immediately activates to prevent excessive movement, ensuring stable and reliable operation and reducing welding defects and equipment failures caused by feed deviations.

[0038] The outer frame is connected to the body through a plug-in rod. This connection method not only ensures a stable connection between the fixing mechanism and the body, but also facilitates disassembly and maintenance when necessary, thereby improving the overall reliability and maintainability of the equipment.

[0061] The moving mechanism 5 has a welding mechanism 4 installed below it. The moving mechanism 5 includes a first sliding seat 502, one end of which is mounted with a cylinder 501. A second sliding seat 503 is mounted on the first sliding seat 502. The second sliding seat 503 is lifted and slid on the first sliding seat 502 by the cylinder 501. This dual-sliding seat structure design enables the welding mechanism 4 to be flexibly moved in both horizontal and vertical directions, greatly improving the convenience and accuracy of the welding operation.

[0062] Welding mechanism 4, comprising a pressing plate 402, on which a guide side plate 403 is mounted, on which a disc electrode 401 is mounted, and a cooling nozzle is mounted behind the pressing plate 402, which is located behind the disc electrode 401. The cooling nozzle adopts a high-efficiency atomization design, which can quickly and evenly spray the coolant on the welding part, timely cool the welding area, prevent welding deformation, and extend the service life of the electrode;

[0063] The fixing mechanism 3 includes an outer frame 307, an inner frame 304 is slidably installed in the outer frame 307, and a plug rod 303 is provided at the bottom end of the outer frame 307. The outer frame 307 is supported and installed on the body 6 through the plug rod 303 and the elastic member 605 on the body 6. This installation method can not only realize the flexible installation and disassembly of the fixing mechanism 3, but also effectively reduce the vibration effect during the welding process through the buffering effect of the elastic member 605; mounting plates 302 are provided at both ends of the inner frame 304, and pressure wheels 301 and wiper plates 3 are respectively installed on the mounting plates 302 at both ends of the inner frame 304. 08, the pressure wheel 301 can press the steel coil tightly to prevent the steel coil from moving during welding and ensure the welding quality; the scraper 308 can promptly remove water stains and impurities on the surface of the steel coil to provide a good working surface for welding; a slide groove 306 is provided in the outer frame 307, and a pulley 305 is provided on the outer side of the inner frame 304. The inner frame 304 is installed in the outer frame 307 through the cooperation between the pulley 305 and the slide groove 306. This cooperation between the pulley and the slide groove can reduce the friction resistance of the inner frame 304 when sliding, making the movement of the inner frame 304 smoother and facilitating the installation and adjustment of the steel coil;

[0064] Circulation mechanism 2 includes a liquid collection hopper 203 and a water tank 204. The liquid collection hopper 203 features a large opening that quickly collects the coolant generated during welding, preventing it from spilling. A conduit 201 is mounted on one end of the liquid collection hopper 203, which is mounted on the water tank 204 via a support rod 202. The coolant in the water tank 204 is pumped into the cooling nozzle via a circulating pump. The circulating pump utilizes a highly efficient, energy-saving pump body, ensuring stable coolant delivery while reducing energy consumption. This circulation system continuously supplies coolant to the cooling nozzle, ensuring effective cooling of the welding mechanism 4 and maintaining normal operation of the equipment.

[0065] The feeding mechanism 1 has an efficient feeding capacity and a precise guiding function, and can quickly and accurately transport the steel coil to the welding position. Two symmetrically distributed support rollers 112 are rotatably installed on the feeding mechanism 1. Driven gears 104 are installed at both ends of the support rollers 112. A transmission gear 105 is provided on the feeding mechanism 1. The two support rollers 112 are connected by the driven gear 104 and the transmission gear 105. This gear transmission method has high transmission efficiency and can ensure the stability and synchronization of the feeding speed; a bracket 102 is installed above the support roller 112 on the feeding mechanism 1. The bracket 102 is installed on the feeding mechanism 1 through an elastic pull rod 106. The elastic pull rod 106 can automatically adjust the height of the bracket 102 according to the thickness of the steel coil to ensure The pressure between the pressure roller 103 and the support roller 112 is uniform, which effectively prevents the steel coil from slipping during the feeding process. Hydraulic cylinders 101 are provided at both ends of the bracket 102, and the pressure roller 103 is installed on the bracket 102 through the hydraulic cylinder 101; the support roller 112 and the pressure roller 103 are sleeved with a guide splint 113, and the guide splint 113 is provided with a first rack 111. The feeding mechanism 1 is provided with a second gear 119. There are two guide splints 113 in total. The two guide splints 113 are meshed with the second gear 119 through the first rack 111. This transmission method can accurately control the opening and closing of the guide splint 113 to achieve precise guidance and positioning of the steel coil; a material coil 110 is supported on one side of the feeding mechanism 1 through the support frame 109;

[0066] The limiting assembly 7 can accurately control the position of the feeding mechanism 1 to ensure the accuracy and safety of the welding work. The limiting assembly 7 includes a guide rod 712, a pull plate 701, a receiving plate 708 and a guide block 709. The receiving plate 708 is rotatably mounted on the support plate 603 of the body 6 through a torsion spring and a second fixed seat 706. This installation method allows the receiving plate 708 to rotate flexibly to adapt to the limiting requirements of different angles. The body 6 is also provided with a supporting electrode plate 602. The supporting plate 603 is located on both sides of the supporting electrode plate 602. The support plate 603 is provided with a countersunk hole 606, an elastic member 605 is installed in the countersunk hole 606, and the elastic member 605 can provide a buffer and reset function for the receiving plate 708, effectively reducing the impact force during the limiting process. A limiting seat 705 is also installed on the support plate 603, and a third rack 704 is slidably installed in the limiting seat 705. A third gear 707 is provided on the receiving plate 708. Through the cooperation of the third rack 704 and the third gear 707, accurate limiting control can be achieved. A pull plate 701 is installed on the support plate 603 through the first fixed seat 702, and the pull plate 701 is slidably installed in the first fixed seat 702 through the limiting block and the limiting groove. The first fixed seat 702 limits the movable angle of the pull plate 701 to ensure that the movement of the pull plate 701 is accurate and reliable. The third rack 704 is connected to the pull plate 701 through the pull wire 703. This pull wire transmission method has a simple structure and reliable transmission, and can achieve long-distance limit control. The bottom end of the guide rod 712 away from the support plate 603 is provided with a guide column 711, and the guide block 709 is rotatably installed on the feeding mechanism 1 through the rotating seat. A guide groove 710 is provided on the guide block 709, and a guide is installed on the lower surface of the end of the guide block 709 away from the feeding mechanism 1. The wheel 713, the guide column 711, the guide groove 710 and the guide wheel 713 cooperate with each other to provide precise guidance for the feeding mechanism 1, ensuring that the feeding mechanism 1 moves along the predetermined track; a power cord 604 is provided on the back of the slide rail 601, and the power cord 604 is electrically connected to the disc electrode 401; the contact end surfaces of the guide side plate 403 and the mounting plate 302 are both inclined surfaces, and the welding mechanism 4 is inserted into the inner frame 304 through the inclined surface guidance of the guide side plate 403 and the mounting plate 302. This inclined surface guiding design enables the welding mechanism 4 to be quickly and accurately inserted into the fixing mechanism 3, thereby improving work efficiency.

[0067] Example 2

[0068] In order to further improve the stability, flexibility and safety of the feeding mechanism, ensure that the steel coils are accurately fed during processing and the equipment operates reliably, for example, Figures 12 to 13 As shown, the present invention also includes:

[0069] The bottom end of the feeding mechanism 1 is provided with a moving seat 108, and the moving seat 108 is provided with a base 117. Moving wheels 107 are rotatably installed on both sides of the base 117. The surface of the moving wheel 107 has been specially anti-slip and wear-resistant treated, and the material of high-strength rubber and metal wheel hub is used. While ensuring the smoothness of movement, the friction with the track is greatly enhanced, effectively preventing slipping, and it can operate stably even under complex working conditions. The moving wheels 107 on both sides of the base 117 are connected by a rotating shaft 121, and a first bevel gear 122 is installed on the rotating shaft 121. Two coaxial second bevel gears 123 are installed in the base 117, and the bottom end of the second gear 119 is connected to the third bevel gear 124 through a safety clutch 120. The safety clutch 120 adopts an overload protection design with sensitive response and reliable action. When the system is overloaded or stuck, it can quickly cut off power transmission, effectively protecting the key components of the equipment from damage. At the same time, it has an automatic reset function, which is convenient for troubleshooting When the gear 112 is in the gear 114, the second gear 119 is driven by the first bevel gear 122, the second bevel gear 123 and the third bevel gear 124. This precise and rapid response successfully prevents the guide plate 113 from further squeezing the material coil 110, allowing the material coil 110 to maintain its intact shape and provide high-quality raw material for subsequent welding. It also prevents damage to other parts of the feeding mechanism due to excessive load, reduces equipment maintenance costs and downtime, and ensures the continuous, stable, and efficient operation of the entire feeding system.

[0070] A second rack 115 is provided at the bottom end of the base 117, and a motor 118 is installed at the bottom end of the body 6 between the rails 8. A first gear 116 is installed at the output end of the motor 118. The motor 118 drives the first gear 116 to engage the second rack 115, so that the feeding mechanisms 1 on both sides of the body 6 move toward or in opposite directions. This driving method is flexible in operation and precise in control. It can quickly adjust the position of the feeding mechanism 1 to meet the processing requirements of steel coils of different specifications, thereby significantly improving production efficiency.

[0071] Example 3

[0072] In order to achieve precise position linkage control between the feeding mechanism and the machine body, ensure smooth connection between each link in the steel coil processing process, and improve the level of equipment automation operation, for example, Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 13 As shown, the present invention also includes:

[0073] When the feeding mechanism 1 is close to the machine body 6, the guide column 711 of the guide rod 712 slides into the guide groove 710 of the guide block 709, and the guide block 709 is opened by the guiding effect of the guide groove 710. The guide groove 710 adopts a special arc-shaped opening structure, and the inner wall is also processed with high precision. There is a very small gap when the two cooperate, so that the guide block 709 can be opened steadily and smoothly through the powerful and precise guiding effect of the guide groove 710. At this time, the guide block 709 pushes the pull plate 701 to deflect through the guide wheel 713, and the guide wheel 713 installed on the guide block 709 is rotated. 13 is made of high-strength, wear-resistant material with an anti-slip surface treatment. When in contact with the pull plate 701, it utilizes excellent friction to forcefully and stably push the pull plate 701 in its deflection. The pull plate 701 is slidably mounted within the first fixed seat 702 via a stop block and a stop slot. This structural design not only precisely limits the movable angle of the pull plate 701 but also ensures precise, shake-free movement when subjected to force. This allows the pull plate 701 to reliably pull the third rack 704 via the pull wire 703, which then engages the third gear 707 to deploy the receiving plate 708. Throughout this process, the various components work closely together, resulting in smooth movement. This allows the receiving plate 708 to be deployed quickly and accurately when the feeding mechanism 1 approaches the machine body 6, significantly improving work efficiency and the continuity of equipment operation.

[0074] When the feeding mechanism 1 is reset, the receiving plate 708 is reset by the torsion spring. During the resetting process of the receiving plate 708, the resetting power is stably transmitted through the precise engagement of the third gear 707 and the third rack 704. Due to the high-precision manufacturing process and reasonable transmission ratio design of the two, the third rack 704 can accurately pull the pull plate 701 to reset through the pull wire 703. During the resetting process, the pull plate 701 also benefits from the precise limiting structure between it and the first fixed seat 702, and can be smoothly reset along the predetermined trajectory without offset or jamming. This ingenious reset design ensures that the entire linkage system can quickly return to its initial state after the feeding mechanism 1 completes a working cycle, and is ready for the next work, effectively improving the degree of automation and work efficiency of the equipment, while also reducing the failure rate and maintenance cost of the equipment.

[0075] Example 4

[0076] In order to ensure the welding quality of steel coils, improve welding efficiency and realize the recycling of coolant, for example, Figures 8 and 9 As shown, the present invention also includes:

[0077] The pressure roller 301 is used to press and level the steel coil. Its unique curved design allows for a highly consistent fit with the coil surface, ensuring uniform pressing and leveling. During the pressing process, the pressure roller 301 effectively eliminates minor surface irregularities such as wrinkles and bumps, providing a smooth, even weld surface for subsequent welding, significantly improving weld quality and results. Furthermore, the pressure roller 301 features a highly flexible rotational design, supported by high-precision bearings. While applying pressure to the coil, it smoothly rotates with the coil's movement, reducing friction and preventing scratches on the coil surface, ensuring the coil's surface quality remains intact.

[0078] The 401 Disc Electrode is made from a specially formulated alloy material with excellent electrical conductivity and resistance to arc erosion, generating a stable and powerful arc during welding. The disc-shaped design of the 401 Disc Electrode provides a larger contact area with the steel coil, enabling continuous and uniform welding during roll welding, effectively improving welding efficiency. Its finely polished, smooth surface reduces slag adhesion during welding, reduces cleaning frequency, and further improves work efficiency. Furthermore, the 401 Disc Electrode exhibits excellent heat dissipation properties, rapidly dissipating heat generated during welding. This prevents excessive temperatures from affecting the electrode's lifespan and weld quality, ensuring long-term, stable welding.

[0079] The wiper 308 is made of highly elastic and wear-resistant rubber material, and its edges have been specially ground, making it soft yet with a certain scraping force. This design enables it to fit tightly against the surface of the steel coil and efficiently scrape off the cooling water sprayed from the cooling nozzle without damaging the steel coil. The scraping action of the wiper 308 is very smooth, and it can quickly gather the cooling water into a stream, guiding it to flow smoothly into the liquid collecting hopper 203. The liquid collecting hopper 203 has the characteristics of large capacity and efficient diversion. Its opening is large and funnel-shaped, which can quickly collect cooling water and prevent it from splashing everywhere. The collected cooling water is sent to the water tank 204 through the conduit 201. The entire transportation process adopts a sealed pipeline design, which effectively avoids leakage and evaporation loss of the coolant. The circulation pump uses energy-saving and high-efficiency products, which can stably send the coolant in the water tank 204 into the cooling nozzle to achieve the recycling of the coolant. This coolant circulation system is not only energy-saving and environmentally friendly, greatly reducing production costs, but also can continuously provide sufficient coolant to the cooling nozzle, ensuring effective cooling of the welding area during welding, maintaining the normal operating temperature of the equipment, and extending the service life of the equipment.

[0080] Example 5

[0081] In order to achieve accurate positioning, efficient operation and stable operation during the steel coil welding process, for example, Figure 1 、 Figure 2 、 Figure 8 and Figure 9 As shown, the present invention also includes:

[0082] Cylinder 501 drives the second sliding seat 503 downward, lowering the welding mechanism 4. Guided by the inclined surfaces of the guide side plates 403 and the mounting plate 302, the welding mechanism 4 is inserted into the inner frame 304 of the fixing mechanism 3. This high-precision inclined guide design allows the welding mechanism 4 to be inserted into the inner frame 304 of the fixing mechanism 3 with extremely high alignment accuracy, effectively avoiding inaccurate welding position caused by insertion deviation, laying the foundation for subsequent high-quality welding. This design also reduces collisions and friction during the insertion process, extending the service life of the components.

[0083] The steel coil is placed between the support roller 112 and the pressure roller 103 of the feeding mechanism 1. The surface of the support roller 112 adopts a non-slip texture design and is made of high-strength alloy steel. It can provide stable support for the steel coil and prevent the steel coil from rolling or shifting during the placement process. The pressure roller 103 is driven down by the hydraulic cylinder 101 to clamp the steel coil. When the pressure roller 103 descends, it can evenly clamp the steel coil, ensuring that the clamping force is sufficient to prevent the steel coil from moving during processing and avoid damaging the surface of the steel coil due to excessive pressure. In addition, the parallelism between the pressure roller 103 and the support roller 112 has been strictly calibrated to ensure that the steel coil remains horizontal when clamped, further improving the processing accuracy.

[0084] The design of the mobile mechanism 5 fully considers the stability and flexibility of the equipment operation. It cooperates with the slide rail 601 with a high-precision linear guide pair. The slide rail 601 has been quenched and hardened, with high surface hardness and strong wear resistance. The slider of the mobile mechanism 5 is installed with high-precision ball bearings, which can greatly reduce the sliding friction resistance. When the mobile mechanism 5 slides on the body 6 through the slide rail 601, the operation is very stable and the positioning accuracy can reach the micron level. During the movement process, the mobile mechanism 5 is also equipped with a high-precision displacement sensor, which can monitor its own position in real time and feed back the data to the control system to ensure that the welding mechanism 4 can move to the welding position accurately. This high-precision mobile control not only improves the welding efficiency, but also ensures the consistency of the welding quality. It can operate stably and reliably even in a long-term, high-intensity working environment.

[0085] Example 6

[0086] In order to achieve high-precision, high-efficiency and automated control of the steel coil welding process, improve welding quality and production efficiency, and reduce manual intervention and equipment loss, for example, Figures 1 to 13 As shown, the present invention also includes:

[0087] A welding method for a splicing welding device based on steel coil processing comprises the following steps:

[0088] S1. Stretch the steel coil and place it between the support roller 112 and the pressure roller 103 of the feeding mechanism 1. The surface of the support roller 112 is treated with a special anti-slip and wear-resistant coating. Combined with the high-strength alloy steel material, it can provide stable and reliable support for the steel coil, and effectively prevent the steel coil from rolling or shifting during the placement process. Start the motor 118. The motor adopts a high-performance servo drive system with the characteristics of fast response speed and high control accuracy. It can accurately adjust the speed and torque according to the preset program. The motor 118 drives the first gear 116 to engage the second rack 115. The first gear 116 and the second rack 115 are both processed by high-precision milling. The tooth shape is standard, the meshing is tight, the transmission efficiency is high and the noise is low. Through this precise gear and rack transmission method, the feeding mechanism 1 on both sides of the body 6 can move toward each other in a stable and synchronous state, ensuring the accurate position of the steel coil during the feeding process and preparing for subsequent processing steps;

[0089] S2. When the feeding mechanism 1 moves, the moving wheel 107 is made of high-strength and wear-resistant rubber material, which has good grip and shock absorption performance when in contact with the track, and can ensure that the feeding mechanism 1 moves smoothly. The moving wheel 107 drives the second gear 119 through the first bevel gear 122, the second bevel gear 123 and the third bevel gear 124 on the rotating shaft 121. These bevel gears are made of high-quality alloy steel and are carburized and quenched. The tooth surface hardness is high and the wear resistance is strong. The meshing accuracy between the gears is extremely high, and the power loss during the transmission process is small. Through this multi-stage bevel gear transmission structure, the power of the moving wheel 107 can be efficiently and stably transmitted to the second gear 119, driving the guide splint 113 to move. The movement accuracy of the guide splint 113 is guaranteed by a precise transmission system, which can achieve precise centering alignment of the material coils 110 on both sides, ensuring that the steel coils are in an ideal position before welding, effectively improving the accuracy and quality of welding;

[0090] S3. When the feeding mechanism 1 is close to the machine body 6, the guide column 711 of the guide rod 712 is precisely ground and has a smooth surface and extremely high dimensional accuracy, and can accurately slide into the guide groove 710 of the guide block 709. The guide groove 710 adopts a special curved surface design, and has good guiding performance and stability when combined with the guide column 711. The guide block 709 pushes the pull plate 701 to deflect, and the pull plate 701 is slidably installed in the first fixed seat 702 through the limit block and the limit groove. This structural design can accurately limit the movable angle of the pull plate 701 to ensure its accurate movement. The pull plate 701 pulls the third rack 704 through the pull wire 703. The pull wire 703 is made of a special material with high strength and low expansion rate, which can ensure the stable transmission of pulling force. The third rack 704 meshes with the third gear 707 to unfold the receiving plate 708. The high-precision meshing of the third rack 704 and the third gear 707 can efficiently transmit power, allowing the receiving plate 708 to unfold quickly and stably, providing reliable support for the positioning and fixation of the steel coil;

[0091] S4. Drive the pressure roller 103 downward through the hydraulic cylinder 101. The hydraulic cylinder 101 is equipped with advanced pressure sensors and intelligent control systems, which can automatically adjust the output pressure and the descent speed according to the actual thickness and material of the steel coil. When the pressure roller 103 descends, it can clamp the steel coil with uniform and stable pressure, which not only ensures that the clamping force is sufficient to prevent the steel coil from moving during processing, but also avoids damage to the surface of the steel coil due to excessive pressure. At the same time, the parallelism between the pressure roller 103 and the support roller 112 is strictly calibrated and monitored in real time to ensure that the steel coil remains horizontal in the clamped state, further improving the positioning accuracy and processing quality of the steel coil. Subsequently, the steel coil is delivered to the welding position through a precise feeding system. The feeding system can achieve high-precision position control according to the preset program and the position information fed back by the sensor, ensuring that the steel coil accurately reaches the required welding position;

[0092] S5, the moving mechanism 5 slides on the body 6 through the slide rail 601. The slide rail 601 adopts a high-rigidity linear guide design, and the surface is quenched, hardened and precision-ground, with extremely high wear resistance and straightness. The slider of the moving mechanism 5 is internally installed with high-precision ball bearings and pre-tightening devices, which can greatly reduce the sliding friction resistance and improve the smoothness and precision of the movement. The cylinder 501 adopts high-precision servo control technology, which can achieve precise adjustment of the output force and displacement. Its cylinder body is precisely machined, with a smooth inner wall and excellent sealing performance. Combined with high-quality piston components, it can effectively reduce gas leakage and ensure stable driving force. When the cylinder 501 drives the second sliding seat 503 to descend, with its precise stroke control capability, it can smoothly and accurately send the welding mechanism 4 to the predetermined height to prepare for the welding operation;

[0093] S6. The welding mechanism 4 is inserted into the inner frame 304 of the fixing mechanism 3 through the bevel guide of the guide side plate 403 and the mounting plate 302. The guide side plate 403 and the mounting plate 302 are both processed by high-precision CNC machine tools. The bevel angle error of the contact end faces of the two is extremely small. Through this high-precision bevel guide design, the welding mechanism 4 can be inserted into the inner frame 304 with extremely high alignment accuracy, effectively avoiding the problem of inaccurate welding position caused by insertion deviation. After insertion, the inner frame 304 is driven to move in the outer frame 307 by an internal drive device. The drive device adopts a high-precision screw nut transmission mechanism, which can realize smooth and precise movement of the inner frame 304. The pressure wheel 301 is made of high-hardness alloy steel and undergoes a special heat treatment process to form a dense hardened layer on its surface. It not only has excellent wear resistance, but also has excellent pressure resistance. The unique arc-shaped design makes it highly compatible with the surface of the steel coil, and can evenly press and flatten the steel coil, eliminating tiny wrinkles and unevenness on the surface of the steel coil, providing a good basic surface for welding;

[0094] S7, disc electrode 401 is used for rolling welding of steel coils. Disc electrode 401 is made of a specially formulated alloy material with excellent electrical conductivity and resistance to arc erosion, and can generate a stable and strong arc during the welding process. Its disc shape design makes its contact area with the steel coil larger, and it can achieve continuous and uniform welding during rolling welding, effectively improving welding efficiency. At the same time, the cooling nozzle adopts an efficient atomization design, which can spray the coolant evenly on the welding part, quickly take away the heat generated during the welding process, and efficiently cool the welding part to prevent welding deformation and ensure welding quality. The cooling system is also equipped with a temperature sensor that can monitor the temperature of the welding area in real time and automatically adjust the flow of coolant according to temperature changes to achieve precise cooling;

[0095] S8, the wiper 308 scrapes off the coolant. The wiper 308 is made of highly elastic and wear-resistant rubber material. Its edge has been specially ground, making it soft yet with a certain scraping force. It can fit tightly to the surface of the steel coil and efficiently scrape off the coolant without damaging the steel coil. The coolant is collected by the liquid collecting hopper 203. The liquid collecting hopper 203 adopts a large opening and funnel-shaped design, which can quickly and effectively collect the coolant and prevent the coolant from splashing everywhere. The collected coolant is sent to the water tank 204 through the conduit 201. The conduit 201 is made of corrosion-resistant material and has a smooth inner wall, which can ensure the smooth delivery of the coolant. The entire coolant circulation system is equipped with an efficient filtering device, which can promptly remove impurities in the coolant, ensure the cleanliness of the coolant, extend the service life of the coolant, realize the recycling of the coolant, and achieve the purpose of energy saving and environmental protection;

[0096] S9. When the feeding mechanism 1 is reset, the receiving plate 708 is reset by a torsion spring with excellent performance. The torsion spring is made of a special alloy material with good elasticity and fatigue resistance. It can maintain a stable elastic force during long-term use, ensuring that the receiving plate 708 is reliably reset. During the resetting process of the receiving plate 708, the resetting power is stably transmitted through the precise engagement of the third gear 707 and the third rack 704. Due to the high-precision manufacturing process and reasonable transmission ratio design of the two, the third rack 704 can accurately pull the pull plate 701 to reset through the pull wire 703. During the resetting process, the pull plate 701 also benefits from the precise limiting structure between it and the first fixed seat 702, and can be reset smoothly along the predetermined trajectory without offset or jamming, ensuring that the entire system can quickly and accurately return to its initial state and be ready for the next welding work.
