Description

Technical Field

[0001] This invention relates to the field of metal welding technology, specifically to an integrated automatic submerged arc welding machine for H-shaped steel. Background Technology

[0002] Automatic submerged arc welding machines are key equipment for efficient and high-quality welding, especially suitable for long straight welds and circumferential welds of medium and heavy steel plates. Its full name is "submerged arc automatic welding machine". The core is "submerged arc". The electric arc burns under a layer of granular flux. This method isolates the air, ensures welding quality, avoids arc radiation and fumes, and improves the working environment. It is widely used in the welding of steel structural components such as H-beams.

[0003] In most existing automatic submerged arc welding machines, the flux feeding mechanism and the wire feeding mechanism are driven by independent motors or preset constant speeds. The feeding speed cannot be adjusted in real time and automatically according to the actual travel speed of the welding device. When the welding speed fluctuates due to changes in workpiece length, welding process adjustments, or uneven manual pushing speed, the supply of flux and wire cannot respond synchronously, which can easily lead to material accumulation or shortage, seriously affecting welding quality and production efficiency. Although some equipment has achieved feedback adjustment of the feeding speed through sensors and control systems, its structure is complex, its cost is high, and its operating environment is strictly required, making it unsuitable for small or simple welding processing scenarios. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated automatic submerged arc welding machine for H-beams to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an integrated automatic submerged arc welding machine for H-beam steel, comprising a base and welding components. Welding components are symmetrically arranged on both sides of the base. Each welding component includes a base. Bases are symmetrically arranged on both sides of the base, and traveling wheels are symmetrically arranged on both sides of the base. A flux chamber is provided inside the base, and a feeding pipe is provided on one side of the flux chamber. A discharge trough is provided on one side below the flux chamber, and a discharge pipe is connected below the discharge trough. A plate wheel is rotatably connected inside the discharge pipe. Feeding wheels are symmetrically arranged on both sides of the feeding pipe, and a synchronous wheel is connected to one side of the feeding wheels. A discharge pipe is provided below the feeding pipe on the base, and a welding head is provided on one side of the discharge pipe on the base.

[0006] Furthermore, the plate wheel axle and the synchronous wheel on one side of the feeding pipe are connected to the walking wheel axle on one side of the base via belts and pulleys, and the synchronous wheels mesh with each other. The outer edge of the plate wheel is in contact with the inner wall of the discharge trough, and the discharge pipe is connected to the flux chamber through the discharge trough. The lower wall of the flux chamber is inclined.

[0007] Furthermore, a motor is installed on one side of the base, and a drive wheel is connected to one side of the motor. A transmission wheel is installed on one side of the drive wheel, and a bidirectional lead screw is installed in the center of the transmission wheel. A slide rod is installed on the other side of the base.

[0008] Furthermore, the drive wheel meshes with the transmission wheel, the bidirectional lead screw is threadedly connected to the base, and the slide rod is slidably connected to the base.

[0009] Furthermore, a telescopic rod is provided on the side of the base away from the base platform, and limit rods are symmetrically provided on both sides of the telescopic rod on the base. One end of the telescopic rod is connected to a clamping plate, and guide wheels are rotatably connected to the opposite side of the clamping plate and the base. The clamping plate is slidably connected to the limit rod.

[0010] Furthermore, three sets of stirring rods are rotatably connected inside the flux tank, and a return trough is provided on one side of the flux tank. A guide plate is rotatably connected to one side of the return trough, and a baffle plate is rotatably connected to the inside of the return trough through a torsion spring shaft. A conveyor belt is provided inside the return trough, and a return frame is provided on the conveyor belt.

[0011] Furthermore, the stirring rod is connected to the traveling wheel via a belt and pulley, and the stirring rods are connected to each other via a chain and sprocket. The baffle plate is elastically connected to the return trough via a torsion spring shaft. The conveyor belt is connected to the traveling wheel on the other side of the base via a belt and pulley, and the return frames are equidistantly distributed on the conveyor belt.

[0012] Furthermore, the lower surface of the base is provided with a sliding groove, and a sliding plate is engaged within the sliding groove. A collection frame is connected below the sliding plate, and oscillating springs are symmetrically connected to both sides of the sliding plate. A top rod is connected to one side of the collection frame, and a grooved wheel is provided on one side of the top rod.

[0013] Furthermore, the slide plate is slidably connected to the base via a slide groove, and the slide plate is elastically connected to the slide groove via a oscillating spring. The top rod is in contact with the inner wall of the grooved wheel, and the grooved wheel is connected to the axle of the traveling wheel.

[0014] Furthermore, the collection frame is provided with a partition, and a shovel plate is connected to one side of the partition. The collection frame is provided with a sieve plate on the top side of the shovel plate.

[0015] This invention provides an integrated automatic submerged arc welding machine for H-beam steel, which has the following advantages: During use, the feeding speed can be automatically adjusted according to the welding speed of the device to avoid material accumulation or shortage. During the process, the flux can be automatically turned over to prevent flux from clumping and causing feeding problems. After welding, the weld can be treated immediately to remove slag and recover flux. The flux is then screened and transferred for reuse. Furthermore, the device can be adjusted according to the size of the steel to accommodate the processing of materials of different sizes.

[0016] 1. In use, as the device moves, the traveling wheel drives the plate wheel to rotate inside the discharge pipe via a belt and pulley, feeding the flux. Simultaneously, the traveling wheel drives the feeding wheel via a synchronous wheel to feed the welding wire. During welding, the faster the welding speed, the faster the device moves, and the faster the traveling wheel drives the plate wheel and synchronous wheel to rotate, thus increasing the feeding speed of the flux and welding wire. This achieves the effect of adaptive flux feeding, ensuring the normal and stable operation of the flux process and avoiding situations where there is insufficient or excessive flux during welding, which could lead to welding errors.

[0017] 2. Before use, the device can be adjusted via a motor and a bidirectional lead screw to accommodate materials of different sizes. The material is then clamped and fixed to prevent it from tilting during welding, which could lead to welding failure. The guide wheels ensure that the device can move freely on the material during welding. The sliding rod and limit rod restrict the base and clamping plate respectively to prevent them from tilting during movement and causing the clamping to loosen. During welding, as the device moves, the traveling wheels drive the stirring rod to agitate the flux, preventing the flux from clumping in the flux chamber and preventing it from being discharged normally. The guide plate is also pushed to vibrate in the flux chamber, preventing the recovered flux from accumulating on the guide plate and causing blockages that would prevent subsequent flux from flowing back.

[0018] 3. After welding is completed, as the device moves, the shovel plate can immediately shovel up the welding slag and excess flux on the weld seam, and screen the welding slag and flux through the sieve plate. The shoveling speed is synchronized with the traveling speed. At the same time, the traveling wheels drive the top rod to move the collection frame through the grooved wheel, and the vibrating spring drives the collection frame to reciprocate through the sliding plate. The vibrating shovel plate can prevent welding slag from sticking together and reduce the resistance to slag removal. Meanwhile, the sieve plate can accelerate the sliding of welding slag and the separation of flux with the vibration of the collection frame, and prevent the accumulation of blocky welding slag from blocking the flux from passing through the sieve plate. The traveling wheels drive the return frame to move through the conveyor belt, and transfer the flux in the collection frame to the flux bin for recycling, reducing resource waste. The running speed of the conveyor belt is proportional to the traveling speed of the device. The faster the traveling speed, the faster the conveyor belt drives the collection frame to return the material, and prevents the flux from accumulating in the collection frame and causing the sieve plate to be blocked.

[0021] Please see Figures 1 to 6 The present invention provides a technical solution: an automatic submerged arc welding integrated machine for H-shaped steel, comprising a base 1 and a welding assembly 2. The welding assembly 2 is symmetrically arranged on both sides of the base 1. The welding assembly 2 includes a base 201. The base 201 is symmetrically arranged on both sides of the base 1, and the base 201 is symmetrically arranged with traveling wheels 202 on both sides. The base 201 is provided with a flux tank 203, and a feeding pipe 204 is provided on one side of the flux tank 203. A discharge trough 205 is provided on one side below the flux tank 203, and a discharge pipe 206 is connected below the discharge trough 205. A plate wheel 207 is rotatably connected inside the discharge pipe 206. Feeding wheels 208 are symmetrically arranged on both sides of the feeding pipe 204, and a synchronous wheel 209 is connected to one side of the feeding wheel 208. A discharge pipe 210 is provided below the feeding pipe 204 on the base 201, and a welding head 211 is provided on one side of the discharge pipe 210 on the base 201.

[0022] Please see Figures 1 to 5The axle of the plate wheel 207 and the synchronous pulley 209 on one side of the feeding pipe 204 are connected to the axle of the traveling wheel 202 on one side of the base 201 via belts and pulleys, and the synchronous pulleys 209 mesh with each other. The outer edge of the plate wheel 207 is in contact with the inner wall of the discharge trough 205, and the discharge pipe 206 is connected to the flux tank 203 through the discharge trough 205. The lower wall of the flux tank 203 is inclined. A motor 3 is installed on one side of the base 1, and a drive wheel 4 is connected to one side of the motor 3. A transmission wheel 5 is installed on one side of the drive wheel 4. A bidirectional lead screw 6 is provided in the center of the base 1, and a slide rod 7 is provided on the other side of the base 1. The drive wheel 4 meshes with the transmission wheel 5. The bidirectional lead screw 6 is threadedly connected to the base 201, and the slide rod 7 is slidably connected to the base 201. A telescopic rod 8 is provided on the side of the base 201 away from the base 1, and limit rods 9 are symmetrically provided on both sides of the telescopic rod 8. One end of the telescopic rod 8 is connected to a clamping plate 10, and guide wheels 11 are rotatably connected to the opposite side of the clamping plate 10 and the base 201. The clamping plate 10 is slidably connected to the limit rod 9. The specific operation is as follows: During use, the material in the flux chamber 203 falls through the discharge chute 205 between the plates of the plate wheel 207. As the device moves, the traveling wheel 202 drives the plate wheel 207 to rotate within the discharge pipe 206 via a belt and pulley, transferring the flux. When the flux moves to the underside of the plate wheel 207, it falls from the discharge pipe 206 and accumulates on the weld. Simultaneously, the traveling wheel 202 drives the synchronous wheel 209 to rotate. Because the synchronous wheels 209 mesh with each other, the flux... Synchronous pulley 209 drives feeding pulley 208 to rotate in opposite directions on both sides of feeding pipe 204 via axle, feeding welding wire in feeding pipe 204 to the weld seam through unloading pipe 210. Welding head 211 then performs welding at the weld seam. During welding, the faster the welding speed, the faster the device moves, and the faster the traveling wheel 202 drives the plate wheel 207 and synchronous pulley 209 to rotate, thus increasing the feeding speed of flux and welding wire. Before use, motor 3 can drive drive wheel 4 to rotate. The transmission wheel 5 drives the bidirectional lead screw 6 to rotate, adjusting the distance between the base 201 and the base platform 1, allowing the side of the base 201 to fit against the material. Then, the telescopic rod 8 moves the clamping plate 10 to clamp and fix the material. The guide wheel 11 ensures that the device can move freely on the material during welding. The sliding rod 7 and the limiting rod 9 can respectively restrict the base 201 and the clamping plate 10 to prevent them from tilting during movement. During the welding process, as the device moves, the traveling wheel 202 can... A set of stirring rods 12 on the base 201 are driven to rotate by a belt and pulley. Under the action of the sprocket and chain, the three sets of stirring rods 12 can rotate synchronously in the flux tank 203 to loosen the flux, allowing the flux to slide naturally along the inclined surface of the lower wall of the flux tank 203. When the stirring rods 12 in the middle of the base 201 rotate, they can push the guide plate 14 to vibrate in the flux tank 203, preventing the recovered flux from accumulating on the guide plate 14, which would prevent the subsequent flux from flowing back and causing blockage.

[0023] Please see Figures 3 to 6Three sets of stirring rods 12 are rotatably connected inside the flux tank 203. A return chute 13 is provided on one side of the flux tank 203, and a guide plate 14 is rotatably connected to one side of the return chute 13. A baffle plate 15 is rotatably connected to the inside of the return chute 13 via a torsion spring shaft. A conveyor belt 16 is provided inside the return chute 13, and a return frame 17 is provided on the conveyor belt 16. The stirring rods 12 are connected to the traveling wheels 202 via belts and pulleys, and the stirring rods 12 are connected to each other via chains and sprockets. The baffle plate 15 is elastically connected to the return chute 13 via a torsion spring shaft. The conveyor belt 16 is connected to the traveling wheels 202 on the other side of the base 201 via belts and pulleys, and the return frames 17 are evenly distributed on the conveyor belt 16. The base 201 has a groove 18 on its lower surface, and a slide plate 19 is engaged in the groove 18. A collection frame 20 is connected below the slide plate 19, and oscillating springs 21 are symmetrically connected on both sides of the slide plate 19. A top rod 22 is connected to one side of the collection frame 20, and a grooved wheel 23 is provided on one side of the top rod 22. The slide plate 19 is slidably connected to the base 201 through the groove 18, and the slide plate 19 is elastically connected to the groove 18 through the oscillating spring 21. The top rod 22 is in contact with the inner side wall of the grooved wheel 23, and the grooved wheel 23 is connected to the shaft of the traveling wheel 202. A partition 24 is provided inside the collection frame 20, and a shovel plate 25 is connected to one side of the partition 24. A sieve plate 26 is provided on one side of the top of the shovel plate 25 in the collection frame 20. The specific operation is as follows: After welding is completed, as the device moves, the shovel plate 25 can immediately process the weld, scraping up the slag and excess flux on the weld and moving it up the shovel plate 25 to the screen plate 26. When the slag and flux slide along the screen plate 26, the flux can fall through the screen holes on the screen plate 26 to one side of the partition 24 in the collection frame 20, while the slag will slide down the screen plate 26 to the other side of the partition 24. During the movement of the device, the traveling wheel 202 can drive the grooved wheel 23 to rotate synchronously, and push the collection frame 20 to move below the base 201 through the push rod 22. The sliding plate 19 restricts the collection frame 20 through the sliding groove 18 to prevent the collection frame 20 from tilting during movement. When the sliding plate 19 slides with the collection frame 20 in the sliding groove 18, the vibration spring 21 will apply elastic force to the sliding plate 19 and drive the collection frame 20 through the sliding plate 19. The frame 20 moves back, keeping the top rod 22 in contact with the groove surface of the groove wheel 23, causing the collection frame 20 to oscillate back and forth below the base 201. The oscillating shovel 25 can prevent welding slag from sticking and reduce the slag removal resistance. At the same time, the screen plate 26 can accelerate the sliding of welding slag and the separation of welding flux as the collection frame 20 oscillates. Meanwhile, the traveling wheel 202 will also drive the conveyor belt 16 to run in the return trough 13, and the return frame 17 can move with the conveyor belt 16 to transfer the welding flux in the collection frame 20 to the welding flux bin 203. The baffle plate 15 can prevent the welding flux from falling out of the base 201 from the return trough 13, while the guide plate 14 can guide the welding flux. When the return frame 17 contacts the baffle plate 15, it will press it to rotate in the return trough 13. After the return frame 17 passes the baffle plate 15, the baffle plate 15 can immediately rotate under the action of the torsion spring shaft.

[0024] In summary, this automatic submerged arc welding machine for H-shaped steel operates by first driving the drive wheel 4 via the motor 3, which in turn drives the transmission wheel 5 to rotate the bidirectional lead screw 6. This adjusts the distance between the base 201 and the platform 1, allowing the side of the base 201 to fit against the material. Then, the telescopic rod 8 moves the clamping plate 10 to clamp and fix the material, preventing it from tilting during welding and causing welding failure. The guide wheel 11 ensures that the device can move freely on the material during welding. The sliding rod 7 and the limiting rod 9 restrict the base 201 and the clamping plate 10 respectively, preventing them from tilting during movement and causing the clamping to loosen. In use, the material in the flux bin 203 falls through the discharge chute 205 between the plates of the plate wheel 207. As the device moves, the traveling wheel 202 drives the plate wheel 207 to rotate in the discharge pipe 206 via the belt and pulley, transferring the flux. When the flux moves to the underside of the plate wheel 207, it falls from the discharge pipe 206 and accumulates on the weld. At the same time, the traveling wheel 202 drives the synchronous wheel 209 to rotate. Because the synchronous wheels 209 mesh with each other, the synchronous wheel 209 can drive the feeding wheel 208 to rotate in opposite directions on both sides of the feeding pipe 204 via the wheel axle, sending the welding wire in the feeding pipe 204 to the weld through the unloading pipe 210. The welding head 211 then performs welding processing on the weld. During the welding process, the faster the welding speed, the faster the device moves, and the faster the traveling wheel 202 drives the plate wheel 207 and the synchronous wheel 209 to rotate. This results in a faster feeding speed of flux and welding wire, achieving the effect of adaptive feeding of the flux. This ensures the normal and stable operation of the flux process and avoids situations where there is too much or too little flux during welding, which could lead to welding errors. Furthermore, once the traveling wheel 202 on the front side stops rotating, the feeding of flux and welding wire will also stop immediately, preventing the flux from spilling and being wasted. During the welding process, as the device moves, the traveling wheel 202 drives a set of stirring rods 12 on the base 201 to rotate via belt and pulley. Under the action of sprocket and chain, the three sets of stirring rods 12 can rotate synchronously in the flux chamber 203 to loosen the flux, allowing the flux to slide naturally along the inclined surface of the lower wall of the flux chamber 203. This prevents the flux from clumping in the flux chamber 203 and being unable to flow properly. When the stirring rod 12 in the middle of the base 201 rotates, it can push the guide plate 14 to vibrate in the flux chamber 203, preventing the recovered flux from accumulating on the guide plate 14 and causing blockages due to the inability of subsequent flux to flow back. After welding is completed, as the device moves, the shovel plate 25 can immediately process the weld, scraping up the slag and excess flux on the weld and moving it up the shovel plate 25 to the screen plate 26. When the slag and flux slide along the screen plate 26, the flux can fall through the screen holes on the screen plate 26 to one side of the partition 24 in the collection frame 20, while the slag will slide down the screen plate 26 to the other side of the partition 24. During the movement of the device, the traveling wheel 202 can drive the grooved wheel 23 to rotate synchronously, and push the collection frame 20 to move below the base 201 through the push rod 22. The slide plate 19 restricts the collection frame 20 through the slide groove 18 to prevent the collection frame 20 from tilting when it moves. As the slide plate 19 slides in the groove 18 following the collection frame 20, the oscillating spring 21 applies elastic force to the slide plate 19 and drives the collection frame 20 to move back through the slide plate 19, so that the top rod 22 always fits against the groove surface of the groove wheel 23, thereby causing the collection frame 20 to oscillate back and forth under the base 201. The oscillating shovel plate 25 can prevent the welding slag from sticking and reduce the slag cleaning resistance. At the same time, the sieve plate 26 can accelerate the sliding of the welding slag and the separation of the flux with the oscillation of the collection frame 20, and prevent the blocky welding slag from piling up and blocking the flux from passing through the sieve plate 26. At the same time, the traveling wheel 202 will also drive the conveyor belt 16 to run in the return trough 13, and the return frame 17 can move with the conveyor belt 16 to transfer the flux in the collection frame 20 to the flux bin 203. The baffle plate 15 can prevent the flux from falling out of the base 201 from the return trough 13, while the guide plate 14 can guide the flux. When the return frame 17 contacts the baffle plate 15, it will press it to rotate in the return trough 13 without hindering the movement of the return frame 17. After the return frame 17 passes the baffle plate 15, the baffle plate 15 can immediately rotate under the action of the torsion spring shaft to continue to block the flux.
