Description

Technical Field

[0001] The present invention relates to the technical field of flux supply, in particular to a flux supply device for a submerged arc automatic welding machine. Background Art

[0002] The flux supply system of the submerged arc automatic welding machine plays a vital role in the welding process. The flux not only protects the welding area from oxidation in the air, but also promotes the fluidity of the weld metal, improves the stability of the molten pool, and helps control the formation of the weld.

[0003] The document with the prior art publication number CN215698737U provides a flux supply device for a submerged arc automatic welding machine, which squeezes the flux inside the output pipe through a compressed air pipe so that the flux is discharged through the output pipe. At the same time, the motor drives the screw rod, which cooperates with the wire groove inside the fixed seat to facilitate the movement of the fixed seat. At the same time, the limit rod cooperates with the slide to limit the position, and the slide slides inside the first slide groove to facilitate the horizontal movement of the output pipe. When the output pipe needs to be disassembled and fixed, the output pipe is placed on one side of the first auxiliary plate, and then the second auxiliary plate is rotated by the hinge so that the screw inside the second auxiliary plate cooperates and locks with the threaded groove inside the first vertical plate, and then the extrusion plate is slid through the second slide groove, and the extrusion plate is fitted with the output pipe, which is convenient for limiting the position of the output pipe to avoid falling off during work, affecting the flux supply, and convenient for users to use.

[0004] When the existing technology is in use, the flux is discharged through the output pipe. When welding steel plates with inclined surfaces, the existing technology is not convenient for limiting the flux that falls on the weld seam at the inclined surface. As a result, the flux is easily dropped outside the welding area during the inclined surface welding process, resulting in the inability to fully utilize the flux and causing flux waste.

[0005] In summary, the prior art lacks a technology for limiting the position of flux when supplying flux to a weld at an inclined surface. Summary of the Invention

[0013] Preferably, an electric push rod B is fixedly connected to the bottom end of the fixing frame, and a current limiting plate is fixedly connected to the output end of the electric push rod B. The current limiting plate is arranged in sliding contact with the bottom end of the supply pipe.

[0014] Preferably, one end of the weld plugging plate is fixedly connected to a connecting strip, a plurality of positioning holes are opened through the connecting strip, a connecting frame is slidingly provided on the outer wall of the connecting strip, one end of the connecting frame is fixedly connected to the fixed frame, a plurality of positioning rods are slidingly provided on one end of the connecting frame, one end of the positioning rod is movably plugged into the positioning hole, the other end of the positioning rod is fixedly connected to a spring, and the other end of the spring is fixedly connected to the connecting frame.

By setting up a weld plugging plate, the flux that falls into the weld can be received, reducing the flux from the weld and ensuring that the flux is concentrated in the welding area, thereby further reducing the waste of flux. The precise control of the flux improves the use efficiency and reduces the material cost. The position of the weld plugging plate is adjusted by the positioning rod and the connecting strip. It can be flexibly adjusted according to the different thicknesses of the steel plate to ensure that the lower side of the weld can be effectively blocked and adapt to various welding tasks. Whether it is a thin plate or a thick plate, the position of the weld plugging plate can be adjusted to maintain a stable supply of flux. 3. By setting up a transmission mechanism, while driving the traveling seat to move for welding, it will drive the spiral feeding rod to rotate, and automatically supply the flux to the weld. At the same time, the flux pressure plate with a tension spring in the flux box can not only pressurize the flux, but also serve as a reminder to add material. It can effectively improve the flux control during the welding process, ensure stable supply, reduce manual intervention, and improve the welding quality through the pressurization and feeding reminder functions. It not only improves production efficiency and safety, but also enhances the adaptability of the equipment, reduces the complexity of operation, and ensures the consistency of welding quality.

[0021] like Figure 2 As shown, two guide rail frames 101 are fixedly connected to the equipment frame 1 in a symmetrical structure, and a traveling rack 102 is fixedly connected to the equipment frame 1.

[0022] like Figure 3As shown, both sides of the bottom of one end of the walking seat 2 are symmetrically arranged in a vertically symmetrical structure and are rotatably connected to be provided with a plurality of rollers 201, and the rollers 201 are arranged in sliding contact with the guide rail frame 101. The rollers 201 make the walking seat 2 more labor-saving when moving.

[0023] like Figure 4 As shown, the transmission mechanism 3 includes a motor 301, which is fixedly connected to the traveling base 2. A worm 302 is fixedly connected to the output end of the motor 301. An electric push rod A303 is fixedly connected to one end of the worm 302, and a driving wheel 304 is fixedly connected to the other end of the electric push rod A303. The electric push rod A303 prevents the supply of flux when the traveling base 2 is reset. The electric push rod A303 drives the connected driving wheel 304 to move, causing it to mesh with the driven wheel 407.

[0024] A worm wheel 305 is provided on one side of the worm 302 for meshing transmission. A rotating shaft 306 is fixedly connected to the bottom of the worm wheel 305. The rotating shaft 306 is rotatably connected to the traveling seat 2. A traveling gear 307 is fixedly connected to the bottom end of the rotating shaft 306. The traveling gear 307 is meshed with the traveling rack 102 for transmission. When the worm 302 rotates, the rotating shaft 306 connected to the worm wheel 305 is driven to rotate, so that the rotating shaft 306 can drive the traveling gear 307 to rotate. At this time, the traveling gear 307 is meshed with the traveling rack 102, thereby driving the traveling seat 2 to move on the guide rail frame 101.

[0025] like Figure 5 As shown, a guide rod 401 is provided at the top of the flux box 4 for sliding cooperation, a tension spring 402 is fixedly connected to the top of the guide rod 401, and the other end of the tension spring 402 is fixedly connected to the top of the flux box 4, and a flux pressure plate 403 is fixedly connected to the bottom end of the guide rod 401, and the flux pressure plate 403 is slidingly cooperated with the inner wall of the flux box 4, and a supply pipe 404 is fixedly connected to the bottom end of the flux box 4, and the supply pipe 404 is fixedly connected to the walking seat 2, and a universal joint 405 is rotatably provided on the inner wall of the flux box 4, and one end of the universal joint 405 extends into the supply pipe 404 and is fixedly connected to a spiral supply rod 406, and the other end of the universal joint 405 extends through the inner wall of the flux box 4 to the outside and is fixedly connected to a driven wheel 407, and the driven wheel 407 is meshed with the driving wheel 304 for transmission. The motor 301 is used to drive the connected worm 302 to rotate, so that the worm 302 drives the driving wheel 304 connected to the electric push rod A303 to rotate, so that the driving wheel 304 drives the universal joint 405 connected to the driven wheel 407 to rotate, so that the universal joint 405 can drive the connected spiral supply rod 406 to rotate, so that the flux in the flux box 4 can be discharged through the supply pipe 404.

[0026] like Figure 6As shown, the bottom end of the fixed frame 5 is fixedly connected to an electric push rod B501. The output end of the electric push rod B501 is fixedly connected to a flow limiting plate 502. The flow limiting plate 502 is arranged in sliding contact with the bottom end of the supply tube 404. The flow limiting plate 502 can adjust the opening size of the bottom end of the supply tube 404, thereby adjusting the amount of flux required for welds of different sizes. The electric push rod B501 drives the connected flow limiting plate 502 to move, thereby adjusting the opening size of the bottom end of the supply tube 404.

[0027] like Figure 7 As shown, a connecting strip 701 is fixedly connected to one end of the weld plugging plate 7. A plurality of positioning holes 702 are formed through the connecting strip 701. A connecting frame 703 is slidably provided on the outer wall of the connecting strip 701. One end of the connecting frame 703 is fixedly connected to the fixing frame 5. A plurality of positioning rods 704 are slidably provided on one end of the connecting frame 703. One end of the positioning rod 704 is movably plugged into the positioning hole 702. The other end of the positioning rod 704 is fixedly connected to a spring 705. The other end of the spring 705 is fixedly connected to the connecting frame 703. The positioning rod 704 is pulled outward, and the connecting strip 701 on the weld plugging plate 7 is aligned with the hole on the connecting frame 703 and inserted. Then, by loosening the positioning rod 704, the positioning rod 704 is inserted into the positioning hole 702 under the action of the spring 705 to limit the position of the connecting strip 701.

[0028] like Figure 8 As shown, the flux containment mechanism 8 includes two side plates 801, which are slidably engaged with the fixing frame 5. An inclined connecting plate 802 is rotatably connected to each end of each side plate 801. A connecting block 803 is rotatably connected between the other ends of the two inclined connecting plates 802. A threaded rod 804 is rotatably connected to one of the connecting blocks 803. The other end of the threaded rod 804 is threadedly connected to the fixing frame 5. Rotating the threaded rod 804 causes the threaded rod 804 to move the connecting block 803. At this time, the connecting block 803 adjusts the angle between the two inclined connecting plates 802, thereby adjusting the spacing between the two side plates 801.

[0029] When submerged arc welding is required for the weld at the bevel, the side plate 801 and the bevel connecting plate 802 are brought close to the weld at the bevel and the threaded rod 804 is rotated to adjust the separation angle of the two bevel connecting plates 802, thereby adjusting the spacing between the two side plates 801, and blocking the flux falling on welds of different widths. The flux can be effectively controlled in the predetermined welding area to prevent the flux from falling from the bevel due to gravity, which can effectively reduce the waste of flux and improve the efficiency of flux use.

[0030] Working principle: When welding steel plates with inclined surfaces, the device is first adjusted according to the width of the weld between the two steel plates. The threaded rod 804 is rotated so that the threaded rod 804 drives the connecting block 803 to move. At this time, the connecting block 803 adjusts the angle between the two inclined connecting plates 802, thereby adjusting the distance between the two side plates 801. Then, the positioning device is used to position the two steel plates and make the steel plates close to the flux enclosure mechanism 8. Then, pull out the positioning rod 704, align the connecting strip 701 on the weld plugging plate 7 with the hole on the connecting frame 703 and insert it. Then, loosen the positioning rod 704, and under the action of the spring 705, the positioning rod 704 is inserted into the positioning hole 702 to limit the connecting strip 701, so that the weld plugging plate 7 blocks the lower side of the weld. Then, the electric push rod B501 is used to drive the connected flow limiting plate 502 to move, and the size of the bottom opening of the supply pipe 404 is adjusted. Then, the electric push rod A303 is used to drive the connected driving wheel 304 to move, so that the driving wheel 304 is engaged with the driven wheel 407. Then, the motor 301 is used to drive the connected worm 302 to rotate, so that the worm 302 drives the driving wheel 304 connected to the electric push rod A303 to rotate, so that the driving wheel 304 drives the universal joint 405 connected to the driven wheel 407 to rotate, so that the universal joint 405 can drive the connected spiral supply rod 406 to rotate, so that the flux in the flux box 4 can be discharged through the supply pipe 404 and fall onto the weld. At the same time, when the worm 302 rotates, the rotating shaft 306 connected to the worm gear 305 rotates, so that the rotating shaft 306 can drive the traveling gear 307 to rotate. At this time, the traveling gear 307 engages with the traveling rack 102, thereby driving the traveling seat 2 to move on the guide rail frame 101; Then, welding is performed using the submerged arc welding torch 6. During the flux supply process, the tension spring 402 drives the flux pressing plate 403 connected to the guide rod 401 to move downward to pressurize the flux.
