Description

Technical Field

[0001] This invention relates to the field of laser welding technology, specifically to a welding processing device and operating method for electric furnace accessories. Background Technology

[0002] Automatic wire feeding laser welding is an advanced welding technology that uses a high-energy laser beam as a heat source and an automatic wire feeding system to precisely supply welding wire. It can be used in the welding process when producing large electric furnace parts. A fiber laser or semiconductor laser generates a high-energy laser beam, which is focused into a micron-sized spot by an optical system and irradiates the weld seam of the workpiece. At the same time, a wire-drawing feeding mechanism precisely feeds the welding wire to the laser focal area. The wire feeding speed is linked with the laser power and welding speed to ensure that the welding wire melts synchronously at the moment the molten pool is formed. The welding wire fills the weld seam when it is melted by the laser or the preheated workpiece.

[0003] The cleanliness of the welding wire directly affects the welding quality. If the surface of the welding wire is contaminated with oil, moisture, dust, or adhering impurities, it may lead to defects such as porosity, slag inclusions, or lack of fusion, reducing the weld strength and sealing performance. The welding wire can be wiped clean before being fed to the laser focal area. Alternatively, rust on the welding wire surface can also affect welding quality, potentially causing porosity, spatter, or poor fusion. Ordinary wiping cannot eliminate rust on the welding wire surface, and it can be treated by grinding. However, traditional grinding pretreatment methods have shortcomings: grinding the entire welding wire results in material waste, or the welding wire may not be used promptly after grinding, leading to new rust formation on the surface. Grinding can be performed just before the welding wire is fed to the laser focal area. Therefore, this invention provides a welding processing device and operating method for electric furnace accessories. Summary of the Invention

[0004] The purpose of this invention is to provide a welding processing device and operating method for electric furnace accessories to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a welding processing device for electric furnace accessories, comprising: A laser used to emit laser light towards the weld seam of a workpiece; A wire feeding mechanism is fixedly connected to one side of the laser, and welding wire is fed through the wire feeding mechanism. A surface treatment mechanism is fixed at the rear end of the wire feeding mechanism. The welding wire passes through the axis of the surface treatment mechanism. The surface treatment mechanism includes a bobbin fixed on the wire feeding mechanism and a plurality of cleaners arranged in a ring around the bobbin. The plurality of cleaners are arranged and spread out along the length of the welding wire. The cleaner includes a main board fixed on the bobbin, a back support frame fixed at one end of the main board, a wiping head that cooperates with the back support frame to clamp the welding wire, a cloth belt conveyed on the wiping head, a dual control device for clamping and pulling the cloth belt, a dustproof box for storing the cloth belt, and an elastic roll for winding up the waste cloth belt.

[0009] The multi-wheel device includes a square plate frame, pressure rollers arranged in an arc shape at both ends of the square plate frame, a disc gear set that establishes transmission with all the pressure rollers, a first trigger for driving the disc gear set, and a first shaft for transmitting the first trigger. The first shaft is mounted on a second frame, and a gear is fixed on the double-control shaft to transmit transmission with the arc-shaped rack set at the edge of the square plate frame. The second frame supports a vertical shaft fixed in the middle of one side of the square plate frame.

[0010] The middle plate device includes a disc shaft mounted on a first frame, an inner plate fixed at one end of the disc shaft, a second trigger for driving the disc shaft, and an anchor-type rack connected to one end of the second trigger. The anchor-type rack and the gears on the dual control shafts drive the fabric belt, which is conveyed along both sides of the inner plate. The inner plate and the pressure rollers cooperate to clamp the fabric belt. After the second trigger contacts the disc shaft, the anchor-type rack swings synchronously with the disc shaft through the second trigger.

[0011] The telescopic device includes a concave tail frame fixed on the head frame, a concave telescopic frame that slides in a direction under the support of the concave tail frame, a spring supported between the concave telescopic frame and the concave tail frame, a guide rod set in the spring, and two fabric-applying rollers supported on the concave telescopic frame. The fabric-applying rollers support and guide the conveyor belt to change direction. The guide rod is fixed on the concave tail frame and passes through a sliding hole opened on the concave telescopic frame. One end of the electric switch is connected to the concave telescopic frame. The concave telescopic frame moves closer to the concave tail frame to trigger the electric switch to turn on.

[0012] The moving assembly includes a movable frame fixed on an F-frame, an adjusting plate that slides through a plate hole in the movable frame, an arc-shaped spring supporting the movable frame and the adjusting plate, and a traveling shaft mounted on the movable frame. One end of the traveling shaft drives the axle on a toothed roller. The movable frame limits and supports the axle on the toothed roller, and the adjusting plate limits and supports the axle on a guide roller. The impeller assembly includes a wind shaft with one end connected to a motor drive, an impeller fixed at the waist of the wind shaft, an air box wrapped around the outer side of the impeller, an air cylinder fixedly connected to the air box, and an air column that extends and retracts in the air cylinder. The air column is fixedly connected to the F-frame, the air box is fixedly mounted on the head frame, and a gear is provided at the other end of the wind shaft to mesh with the gear provided on the traveling shaft.

[0013] The disc gear assembly includes a fixed shaft fixed in the middle of the square plate frame, a disc gear movably sleeved on the outside of the fixed shaft, a worm gear fixed at the end of the fixed shaft, and a worm gear meshing with the worm gear on one side. One end of the worm gear is movably sleeved in a through hole opened on a U-shaped plate on the square plate frame. After the first triggering element and the end of the worm gear come into contact and dock, the first shaft rotates synchronously with the worm gear through the first triggering element. The waist of the pressure roller is movably sleeved in a shaft hole opened on the square plate frame, and a gear is fixed at one end of the pressure roller to drive the disc gear.

[0014] A method for welding electric furnace accessories includes the following steps: Step 1: Pre-welding preparation. Clean the weld bevel and both sides of the electric furnace accessories to remove contaminants such as oil, scale, cutting fluid or iron filings. Select the appropriate welding wire according to the base material. Step 2: During automatic wire feeding laser welding, stable heat input, narrow weld bead, and minimal oscillation are used to avoid excessive heat input leading to grain coarsening or excessively small grains causing incomplete fusion. Step 3: For thin plates, ring-shaped or long components, adopt measures such as symmetrical welding, segmented welding, skip welding or reverse deformation pre-setting to reduce residual stress; Step 4: Post-weld treatment, grind the weld to a smooth transition surface, and avoid stress concentration sources such as sharp corners and deep undercut.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the welding wire is cleaned and wiped before being fed to the laser focal area to remove oil or impurities from the surface of the welding wire. The welding wire is wiped by the back-and-forth conveying of the cloth belt, and the cloth belt is replaced after multiple back-and-forth conveyings. The contaminated cloth belt is collected and stored, and the new cloth belt is used to wipe the welding wire in a partial section.

[0016] 2. In the process of wiping the welding wire with a cloth belt in this invention, if rust is detected on the surface of the welding wire, the rust removal mechanism will be automatically triggered. The conveying triangular closed-loop belt presses against the welding wire, and sandpaper polishes the rusted surface of the welding wire to ensure that there are no surface oxides on the welding wire during welding.

The telescopic device 15 and the welding wire 3 cooperate to support the cloth belt 10, thereby causing the cloth belt 10 to form a V-shaped curve in a certain part. The V-shaped curve of the cloth belt 10 cooperates with the arc surface provided on the back support frame 8 to clamp a certain part of the welding wire 3, and the V-shaped curve of the cloth belt 10 wipes the welding wire 3 by reciprocating conveying.

[0039] Reference Appendix Figure 10 The rust removal device 16 includes a triangular closed-loop belt 19 distributed on one side of the welding wire 3, sandpaper 20 pasted on the outside of the triangular closed-loop belt 19, two toothed rollers 21 arranged on one side of the inside of the triangular closed-loop belt 19, guide rollers 22 arranged on the other side of the inside of the triangular closed-loop belt 19, a moving component 23 for driving the toothed rollers 21, an F-shaped frame 24 for supporting the moving component 23, and a fan wheel assembly 25 for pushing the F-shaped frame 24. One end of the fan wheel assembly 25 is connected to the motor 17 for transmission, and the other end drives the moving component 23. The F-shaped frame 24 slides through the square hole opened on the head frame 14.

[0040] Reference Appendix Figure 13The dual-control device 11 includes a central disc device 26 distributed on one side of the fabric belt 10, a multi-wheel device 27 distributed on the other side of the fabric belt 10, a dual-control shaft 28 for simultaneously driving the central disc device 26 and the multi-wheel device 27, a first frame 29 supporting the dual-control shaft 28, the central disc device 26 being mounted on the first frame 29, and a second frame 30 supporting the multi-wheel device 27. The second frame 30 also supports the elastic winding device 13. Both the first frame 29 and the second frame 30 are fixed on the main board 7. A portion of the dual-control shaft 28 is movably fitted into a through hole opened on the first frame 29.

[0041] Reference Appendix Figure 16 The multi-wheel device 27 includes a square plate frame 31, pressure rollers 32 arranged in an arc shape at both ends of the square plate frame 31, a disc gear set 33 that establishes transmission with all the pressure rollers 32, a first trigger 34 for driving the disc gear set 33, and a first shaft 35 for driving the first trigger 34. The first shaft 35 is mounted on a second frame 30. A gear is fixed on the double control shaft 28 to drive the arc rack set on the edge of the square plate frame 31. The second frame 30 supports a vertical shaft fixed in the middle of one side of the square plate frame 31. The vertical shaft on the square plate frame 31 is movably sleeved in a through hole opened in the second frame 30. A partial section of the first shaft 35 is movably sleeved in a shaft hole opened in the second frame 30.

[0042] Reference Appendix Figure 13The intermediate plate device 26 includes a disc shaft 36 mounted on the first frame 29, an inner disc 37 fixed at one end of the disc shaft 36, a second trigger 38 for driving the disc shaft 36, and an anchor-type rack 39 connected to one end of the second trigger 38. The anchor-type rack 39 and the gears on the dual control shaft 28 are connected for transmission. The cloth belt 10 is conveyed along both sides of the inner disc 37. The inner disc 37 and the pressure roller 32 cooperate to clamp the cloth belt 10. After the second trigger 38 contacts the disc shaft 36, the anchor-type rack 39 swings synchronously with the disc shaft 36 through the second trigger 38. The disc shaft 36 is movably sleeved in a through hole opened on the first frame 29. The second trigger 38 includes a second displacement device 383 fixed on the first frame 29, a second prism cylinder 382 movably sleeved in the through hole opened on the first frame 29, a second prism 381 sliding at the axis of the second prism cylinder 382, ​​and a second post 38 fixed at one end of the second prism 381. 4. The second prism cylinder 382 and the anchor rack 39 are fixedly connected. The second displacement device 383 is an existing technology instrument. The displacement protrusion on the second displacement device 383 is inserted into the annular groove opened on the second pile 384. This does not affect the rotation of the second pile 384. The displacement protrusion on the second displacement device 383 can control the axial movement of the second pile 384. The opposite ends of the second pile 384 and the disc shaft 36 are provided with frosted surfaces or rubber pads. In this way, the second pile 384 and the disc shaft 36 can rotate synchronously after docking. The rotation of the double control shaft 28 drives the anchor rack 39 to swing. Then, the second prism 381 is driven through the second prism cylinder 382, ​​and then the second pile 384 drives the disc shaft 36 to rotate. The disc shaft 36 and the inner disc 37 move synchronously. In this way, the swing of the anchor rack 39 corresponds to the rotation of the inner disc 37. After the second displacement device 383 controls the disc shaft 36 and the second pile 384 to separate, the inner disc 37 can rotate freely.

[0043] The elastic winding device 13 includes a winding shaft 132 with one end movably sleeved in a shaft hole on the second frame 30, a spring 133 fixedly sleeved on the outside of the winding shaft 132, and an I-beam frame 131 fixedly sleeved on the outside of the spring 133. The waste fabric 10 is wound onto the I-beam frame 131. A Y-shaped plate is fixed on one side of the I-beam frame 131, and the winding shaft 132 is also movably sleeved in a through hole in the middle of the Y-shaped plate. The winding shaft 132 is externally connected to a prior art drive mechanism to control the winding of the fabric 10. The spring 133 provides elastic pressure for the winding of the fabric 10 and can also cope with the unwinding release of the fabric 10. When the V-shaped curved section on the fabric 10 rubs the welding wire 3 back and forth, the fabric 10 on the elastic winding device 13 needs to be repeatedly released short distances. Therefore, the spring 133 is provided to allow the fabric 10 to be pulled and released.

[0044] The telescopic device 15 includes a concave tailstock 155 fixed on the headstock 14, a concave telescopic frame 152 that slides directionally under the support of the concave tailstock 155, a spring 154 supported between the concave telescopic frame 152 and the concave tailstock 155, a guide rod 153 disposed in the spring 154, and two fabric-applying rollers 151 supported on the concave telescopic frame 152. The fabric-applying rollers 151 support and guide the conveyor belt 10 to change direction. The guide rod 153 is fixed on the concave tailstock 155 and passes through a sliding hole opened in the concave telescopic frame 152. One end of the electric switch 18 is connected to the concave telescopic frame 152. 152 moves closer to the concave tailstock 155 to trigger the power switch 18. The axle on the fabric roller 151 is movably fitted into a through hole in the concave telescopic frame 152. The end of the concave tailstock 155 extends into a groove in the concave telescopic frame 152. The power switch 18 includes an insulating frame 181 with one end fixed to the concave telescopic frame 152, a conductive plate 183 fixed to the other end of the insulating frame 181, a first half-connecting piece 182 contacted on one side of the conductive plate 183, a second half-connecting piece 184 disposed at one end of the first half-connecting piece 182, and a direct connecting piece 185 disposed on one side of the first half-connecting piece 182. The concave telescopic frame 152... The displacement of the concave telescopic frame 152 causes the insulating frame 181 to move, which in turn causes the conductive plate 183 to move and come into contact with the second half of the conductive piece 184. The first half of the conductive piece 182, the conductive plate 183, and the second half of the conductive piece 184 form the live wire circuit on the motor 17, while the direct conductive piece 185 forms the neutral wire circuit, controlling the power supply between the power source and the motor 17. In summary, the displacement of the concave telescopic frame 152 corresponds to the synchronous displacement of the conductive plate 183. After the conductive plate 183 and the second half of the conductive piece 184 come into contact, the motor 17 is energized and works. That is, when the local rust of the welding wire 3 is detected, the motor 17 is energized to provide power for subsequent cleaning and rust removal work. The principle of corrosion: The V-shaped curved section on the cloth belt 10 contacts the welding wire 3. The V-shaped curved section of the cloth belt 10 reciprocates to wipe the oil or water stains on the surface of the welding wire 3. If the surface of the welding wire 3 is corroded, the friction between the corroded surface and the cloth belt 10 increases. This makes it difficult for the cloth belt 10 to convey the welding wire 3 along the corroded surface. The cloth belt 10 is delayed in conveying, but the force pulling the cloth belt 10 remains unchanged. Then the cloth belt 10 will pull the cloth-applying roller 151 in the opposite direction. The cloth-applying roller 151 is displaced and drives the concave telescopic frame 152. Then the concave telescopic frame 152 moves closer to the concave tail frame 155. The concave telescopic frame 152 drives the insulating frame 181, triggering the subsequent motor 17 to be energized.

[0045] The movable assembly 23 includes a movable frame 231 fixed on an F-frame 24, an adjusting plate 234 that slides through a plate hole in the movable frame 231, an arc-shaped spring 233 supported between the movable frame 231 and the adjusting plate 234, and a traveling shaft 232 mounted on the movable frame 231. One end of the traveling shaft 232 drives the axle on the toothed roller 21. The movable frame 231 limits and supports the axle on the toothed roller 21, and the adjusting plate 234 limits and supports the wheel on the guide roller 22. The shaft and impeller assembly 25 includes a shaft 254 with one end connected to the motor 17 for transmission, an impeller 253 fixed at the waist of the shaft 254, an air box 255 wrapped around the outer side of the impeller 253, an air cylinder 251 fixedly connected to the air box 255, and an air column 252 that extends and retracts in the air cylinder 251. The air column 252 is fixedly connected to the F-type frame 24. The air box 255 is fixed on the head frame 14. A gear is provided at the other end of the shaft 254 to mesh with a gear provided on the traveling shaft 232 for transmission.

[0046] The inner wall of the triangular closed-loop belt 19 has toothed grooves, which allows the toothed roller 21 to rotate stably and drive the triangular closed-loop belt 19 for conveying. The traveling shaft 232 is movably sleeved in a through hole opened in the movable frame 231. One end of the axle of the traveling shaft 232 is fixed with a bevel gear to change the direction of transmission with a bevel gear fixed on the axle of the toothed roller 21. The axles of the two toothed rollers 21 are respectively movably sleeved in two shaft holes opened in the movable frame 231. The end of the bow-shaped spring piece 233 is fixed on the movable frame 231. On the protrusion, the middle part of the bow-shaped spring piece 233 pushes the convex arc plate on the adjusting plate 234 to apply elastic force to the adjusting plate 234. The axle on the guide roller 22 is movably sleeved in the shaft hole opened on the adjusting plate 234. The guide roller 22 tends to move away from the toothed roller 21, forming a stable support for the triangular closed ring belt 19. When the triangular closed ring belt 19 comes into contact with the welding wire 3, it has an inward deformation. The guide roller 22 at the other end is pulled to adapt to the two toothed rollers 21. The fan shaft 254 is fixedly connected to the rotating shaft on the motor 17. After the motor 17 is powered on, it drives the fan shaft 254 to rotate. The fan shaft 254 drives the follower shaft 232, which in turn drives the toothed roller 21. The rotation of the toothed roller 21 causes the triangular closed-loop belt 19 to transport the wire. The sandpaper 20 contacts the rusted surface of the welding wire 3 during the transport, polishing the rusted surface of the welding wire 3 and removing the rust. The sandpaper 20 is close to the welding wire 3 because the fan shaft 254 drives the impeller 253 to rotate, causing airflow. Outside air is drawn into the air box 255 and then injected into the air cylinder 251. The air pressure acts on the air column 252, which drives the F-shaped frame 24 to move. The F-shaped frame 24 drives the moving component 23, which in turn controls the displacement of the toothed roller 21 and the guide roller 22, causing the external triangular closed-loop belt 19 and the sandpaper 20 to move. The sandpaper 20 then comes close to the welding wire 3.

[0047] The disc gear assembly 33 includes a fixed shaft 333 fixed in the middle of the square plate frame 31, a disc gear 334 movably sleeved on the outside of the fixed shaft 333, a worm gear 332 fixed at the end of the fixed shaft 333, and a worm 331 meshing with the worm gear 332 on one side. One end of the worm 331 is movably sleeved in a through hole in a U-shaped plate on the square plate frame 31. After the first trigger 34 and the end of the worm 331 come into contact and mate, the first shaft 35 rotates synchronously with the worm 331 through the first trigger 34. The waist of the pressure roller 32 is movably sleeved in a shaft hole in the square plate frame 31. The first trigger 34 includes a first displacement device 343 fixed on the second frame 30, a first prismatic cylinder 341 movably sleeved in a through hole on the second frame 30, a first prism 342 sliding at the axis of the first prismatic cylinder 341, and a first post 344 fixed at one end of the first prism 342. The first shaft 35 is fixed at the end of a bevel gear to drive the first prismatic cylinder 341 in a different direction. The docking transmission method of the first trigger 34 and the disk gear set 33 is the same as that of the second trigger 38.

[0048] The V-shaped curved section of the fabric belt 10 is repeatedly conveyed to wipe the welding wire 3. The braking principle is as follows: the inner disc 37 and multiple pressure rollers 32 at both ends cooperate to clamp the inlet and outlet belts of the fabric belt 10. The surfaces of the inner disc 37 and the pressure rollers 32 are both friction surfaces, and the fabric belt 10 is tightly clamped. When the pressure rollers 32 and the inner disc 37 do not rotate, the fabric belt 10 is firmly clamped. At this time, the square plate frame 31, the pressure rollers 32 and the inner disc 37 swing synchronously, and the clamped fabric belt 10 will be conveyed back and forth. The V-shaped curved section of the fabric belt 10 wipes the welding wire 3. The driving principle is: the second positioner 383 is energized, and the double... The control shaft 28 rotates back and forth. On one hand, the control shaft 28 drives the anchor rack 39 to swing, which in turn causes the second prism cylinder 382, ​​the second prism 381, the second pile 384, the disc shaft 36 and the inner disc 37 to rotate synchronously. The first displacement device 343 is de-energized, and the first pile 344 and the worm gear 331 are separated, which does not affect the disc gear set 33 from rotating back and forth with the square plate frame 31. On the other hand, the control shaft 28 drives the square plate frame 31, and the square plate frame 31 and the inner disc 37 rotate back and forth synchronously. In this way, under the control of the pressure roller 32 and the inner disc 37, the cloth belt 10 distributed on the telescopic device 15 is conveyed back and forth.

[0049] After the V-shaped curved section on the conveyor belt 10 has been used to wipe the welding wire 3 multiple times, it needs to be transferred away. After this replacement, the new V-shaped curved section on the conveyor belt 10 takes over wiping the welding wire 3. That is, after the conveyor belt 10 has been used for multiple round trips, it will switch to the transfer conveying mode. Specifically, the second positioner 383 switches to the de-energized state, the disc shaft 36 and the second post 384 separate, the inner disc 37 can rotate freely, the first positioner 343 switches to the energized state, the worm gear 331 and the first post 344 are connected for transmission, and the first shaft 35 is externally driven. The drive mechanism controls the rotation, which in turn drives the first prism cylinder 341. Next, the first prism 342 drives the first pile 344 to rotate, which in turn drives the worm gear 331 to drive the worm wheel 332. The fixed shaft 333 drives the disc gear 334 to rotate, causing all the pressure rollers 32 to rotate. The rotation of the pressure rollers 32 drives the fabric belt 10 to be conveyed. At the same time, the fabric winding shaft 132 rotates. The fabric belt 10 conveyed by one end of the inner disc 37 is wound up by the elastic winding device 13, and the fabric belt 10 conveyed by the other end of the inner disc 37 is pulled out from the dust box 12.

[0050] A method for welding electric furnace accessories includes the following steps: Step 1: Pre-welding preparation. Clean the weld bevel and both sides of the electric furnace accessories to remove contaminants such as oil, scale, cutting fluid or iron filings. Select the appropriate welding wire according to the base material. Step 2: During automatic wire feeding laser welding, stable heat input, narrow weld bead, and minimal oscillation are used to avoid excessive heat input leading to grain coarsening or excessively small grains causing incomplete fusion. Step 3: For thin plates, ring-shaped or long components, adopt measures such as symmetrical welding, segmented welding, skip welding or reverse deformation pre-setting to reduce residual stress; Step 4: Post-weld treatment, grind the weld to a smooth transition surface, and avoid stress concentration sources such as sharp corners and deep undercut.
