Description

Technical Field

[0001] The invention relates to the technical field of straight seam submerged arc welding, in particular to a double-sided straight seam submerged arc welding steel pipe manufacturing device. Background Art

[0002] Steel is widely used in the industrial field, especially steel pipes are often used in fields such as pipeline construction. Usually, steel plates are made into round tube shapes through equipment, and then the straight gaps forming the round tubes are welded by welding equipment to form complete round tube-shaped steel pipes. Usually, flux is poured out of the flux box to cover the welding mechanism and the connection between the steel pipe to reduce the contact between the welding process and the air, and then the used flux is recycled through equipment such as vacuum cleaners.

[0003] However, traditional equipment cannot achieve ideal results when recycling flux: after welding is completed, the vacuum cleaner combined with the suction pipe can only recycle part of the flux. Since the steel pipe is round, part of the flux will directly fall under the steel pipe, causing waste, and at the same time affecting the subsequent work of the walking mechanism in the lower area. The other part of the flux will form flaky welding slag under the action of the welding mechanism. The welding slag will greatly reduce the effect of the vacuum cleaner during recovery and cause blockage. The welding slag will also fall to the lower area and affect other components. In addition, traditional equipment usually clamps and fixes the two ends of the steel pipe during welding, which results in the two end areas of the steel pipe not being able to be welded uniformly at one time like the middle area. Therefore, the present invention proposes a double-sided straight seam submerged arc welding steel pipe equipment. Summary of the Invention

[0040] The swing assembly cooperates with the solder recovery structure 12 to make the brush plate 25 swing back and forth, and finally sweep the used flux and welding slag on the steel pipe onto the filter screen 30. At the same time, the guide plate 22 guides and collects the flux and welding slag, preventing the flux and welding slag from being swept to other areas under the action of the brush plate 25 and affecting the equipment components.

[0041] In this embodiment, the top of the base 1 is also provided with a slide rail 2, two clamping mechanisms 4, and two driving mechanisms 5.

[0043] In this embodiment, a hydraulic cylinder 8 is provided on the top of the gantry 7. One end of the hydraulic cylinder 8 passes through the gantry 7 and is fixedly connected to the storage rack 9. A flux box 10 and a welding mechanism 11 are fixedly provided on the outside of the storage rack 9.

[0044] The hydraulic cylinder 8 acts on the storage rack 9 to adjust the height position.

[0045] In this embodiment, a discharge pipe is fixedly provided through the bottom of the flux box 10 , and the welding mechanism 11 is composed of a storage roller, two sets of guide rollers, a frame, two sets of wire feeding rollers, and a guide tube.

[0046] The flux inside the flux box 10 is discharged through the discharge pipe. The flux can bury the welding wire discharged by the welding mechanism 11 to avoid contact with air during the process.

[0047] In this embodiment, the interior of the guide plate 22 is arranged at an angle, and the discharge port of the guide plate 22 is adaptively matched with one of the notches 17 of the hollow storage box 16. The other notch 17 of the hollow storage box 16 is located directly above the feed port of the flux box 10, and the hollow storage box 16 is penetrated by a serrated belt 19.

[0048] The guide plate 22 pours the collected flux into one of the gaps 17 , and under the action of the conveyor belt 18 , the flux in the empty storage box 16 flows out from the other gap 17 and returns to the flux box 10 .

[0049] In this embodiment, a material distribution structure 13 is provided on the outside of the guide plate 22. The material distribution structure 13 includes a filter screen 30, two baffles 32, and a mounting plate 34. The filter screen 30 is rotatably connected to the guide plate 22 through two connecting plates 31. The baffle 32 and the mounting plate 34 are fixedly connected to the guide plate 22. A spring 33 is provided between the baffle 32 and the connecting plate 31. A motor 35 is provided on the outside of the mounting plate 34, and the output shaft of the motor 35 passes through the mounting plate 34 and is fixedly connected to the eccentric wheel 36.

[0050] The material separation structure 13 cooperates with the solder recovery structure 12 to separate the flux and the welding slag. The welding slag is blocked by the filter 30, and the filter 30 vibrates up and down with the cooperation of the eccentric wheel 36 and the spring 33, which can accelerate the flux to fall into the guide plate 22 to avoid blockage.

[0051] In this embodiment, a collection component is provided on the outside of the hollow storage box 16, and the collection component includes a second mounting plate 37, a collection box 38, and two screws 39. The second mounting plate 37 and the hollow storage box 16 are fixedly connected, and the collection box 38 is connected to the second mounting plate 37 through screws 39.

[0052] The collecting assembly cooperates with the material separation structure 13 to collect the welding slag pieces blocked on the filter screen 30. The up and down vibration of the filter screen 30 in cooperation with the eccentric wheel 36 and the spring 33 can accelerate the speed at which the welding slag pieces fall from the filter screen 30 to the inside of the collection box 38.

[0053] In this embodiment, one end of the connecting plate 31 is arranged in a semicircular protrusion shape and adaptively matches the eccentric wheel 36 , the filter screen 30 is arranged in an arc shape, and one end of the filter screen 30 is located in the area directly above the collection box 38 .

[0054] One end of the connecting plate 31 is provided with a semicircular protrusion to better fit the eccentric wheel 36 .

[0055] In this embodiment, a lifting structure 14 is provided on the outside of the gantry 7, and the lifting structure 14 includes two horizontal plates 40. The horizontal plates 40 are fixedly connected to the gantry 7. Two electric push rods 41 are provided on the outside of the horizontal plates 40, and one end of the electric push rod 41 passes through the horizontal plates 40 and is fixed with a storage frame 42. A limiting roller 43 is rotatably provided on the inner side of the storage frame 42, and the limiting roller 43 is set at an angle.

[0056] The lifting structure 14 cooperates with the solder recovery structure 12 and the material distribution structure 13 to support and lift the steel pipe, so that the two end areas of the steel pipe can be welded uniformly like the middle area, and there is no need to move the position of the steel pipe and perform additional welding on the two end areas.

[0057] It should be noted that the present invention is a double-sided straight seam submerged arc welding steel pipe equipment. Before use, the equipment is placed in the required location, flux is poured into the flux box 10, the welding wire is installed on the storage roller of the welding mechanism 11, and one end of the welding wire is passed through two guide rollers, two sets of wire feed rollers, and a guide tube in sequence, finally making the welding wire match the surface position of the steel pipe. The collection box 38 is mounted on the second mounting plate 37 using two screws 39, and the equipment can be put into operation.

[0058] Move one of the clamping mechanisms 4 on the base 1 to one side of the slide rail 2 and stop. Move the gantry 7 to the front of the clamping mechanism 4 in the position just moved through the walking mechanism 6 and stop. Start the electric push rod 41 to act on the storage frame 42 to move the limiting roller 43 toward the middle until the limiting roller 43 matches the position of the steel pipe and stops. Fix one end of the steel pipe through the other clamping mechanism 4. At this time, start the walking mechanism 6 so that the limiting roller 43 near the other end of the steel pipe contacts the steel pipe and lifts it. At this time, the flux inside the flux box 10 flows to the corresponding position on the surface of the steel pipe through the discharge pipe. Under the action of the welding mechanism 11, the welding wire welds the steel pipe. Under the action of the walking mechanism 6, the gantry 7 moves the welding mechanism 11 to weld the steel pipe.

[0059] During the process, the motor 1 20, the motor 27 and the motor 3 35 are started to work, the motor 27 acts on the linkage plate 28 to rotate, and the linkage plate 28 causes the movable rod 24 to swing back and forth with the brush plate 25 through the connecting arm 29, and finally causes the used flux and the flake-shaped welding slag on the surface of the steel pipe to be swept off and fall onto the surface of the filter 30, the welding slag is blocked by the filter 30, and the flux falls directly into the inside of the guide plate 22. Since the guide plate 22 is tilted and the discharge port of the guide plate 22 matches one of the notches 17 of the hollow storage box 16, the flux will flow directly from the notch 17 into the inside of the hollow storage box 16, and the motor 1 20 acts on the gear 21 to rotate, causing the gear The wheel 21 and the serrated belt 19 mesh with each other, so that the conveyor belt 18 transfers the flux inside the hollow storage box 16 to another notch 17 of the hollow storage box 16. Since the notch 17 is located above the feed port of the flux box 10, the flux inside the hollow box 16 will return to the inside of the flux box 10 under the action of the conveyor belt 18. The motor 35 acts on the eccentric wheel 36 to rotate. During the rotation process, the eccentric wheel 36 continuously contacts the connecting plate 31. Under the action of the eccentric wheel 36 and the spring 33, the connecting plate 31 swings up and down with the filter screen 30. The blocked welding slag pieces will fall from the surface of the filter screen 30 into the interior of the collection box 38 under the action of the up and down swinging of the filter screen 30.

[0060] When the gantry 7 moves to the middle position of the steel pipe under the action of the walking mechanism 6, the other end of the steel pipe is welded. At this time, the clamping mechanism 4, which was initially moved, is moved to the corresponding position of the steel pipe through the driving mechanism 5, and the other end of the steel pipe is clamped. When the block is welded to one end of the steel pipe, the clamping mechanism 4 on the other side is moved away from one end of the steel pipe through the driving mechanism 5. Since the limiting roller 43 is in contact with and supports the steel pipe at this time, there is no need to worry about the supporting force problem. At this time, the walking mechanism 6 moves until the steel pipe is completely welded, and then the steel pipe that has just been welded can be taken out through external equipment. The driving mechanism 5 cooperates with the clamping mechanism 4, and the limiting roller 43 cooperates with the clamping mechanism 4, so that the two end areas of the steel pipe can be welded uniformly like the middle area, and there is no need to move the position of the steel pipe and perform additional welding on the two end areas.
