[0015] A forming and using method of a straight seam submerged arc welded steel pipe, wherein the forming and using method of the straight seam submerged arc welded steel pipe is as follows:

[0016] S1. Pour welding material into the interior of the flux box body. The top of the movable plate will squeeze the first connecting tube under the action of gravity. The squeezed first connecting tube will allow the gas inside to enter the interior of the bellows through the first corrugated airbag. The bellows will expand and move upward, causing the resistance plate to press against the bottom surface of the closing plate. As the bellows drive the resistance plate to move upward, the two closing plates will gradually move toward each other, thereby sealing the top of the flux box body.

[0017] S2. Press the push plate downward to rotate the spur gears on both sides. The spur gears will move the outer ends of the movable plates outward. At this time, the four movable plates will move outward from the inside of the lifting bin at the same time. Then, rotate the push plate to drive the lifting bin and the movable plates to rotate inside the flux box body. At this time, the four movable plates will stir the flux material inside the flux box body in layers.

[0018] S3. When the push plate moves downward, the connecting block drives the push rod to squeeze the second corrugated airbag. At this time, the hot air inside the second corrugated airbag will be discharged outward through the air outlet. While the movable plate is used to layer and stir the solder material inside the flux box body, the cooperation of the second corrugated airbag will ensure the heat of the solder material inside the flux box body, preventing it from being partially damp and causing tin frying.

[0019] S4. Press the push plate downward so that its bottom end squeezes the top of the pressing shaft. The pressing shaft moves downward, and will move downward together with the rectangular slot plate and the connecting rod. The top of the connecting rod will pull the rotating shaft downward. At this time, the two hinged rods will cause the bottoms of the two rubber plates to move in opposite directions, so that an opening appears at the bottom, allowing the flux material to be discharged downward. The amount of flux material discharged through the two slots is controlled to avoid a large amount of flux material being discharged downward at the same time, resulting in blockage of the discharge port at the bottom of the flux box body, thereby affecting the subsequent welding effect.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention realizes layered processing of the flux material by arranging the coordination of structures such as the connecting module and the movable module, thereby preventing the flux material from sticking together. The push plate is pressed to cause the spur gear to drive the bottom end of the movable plate to move outward, and the four movable plates will simultaneously move outward from the inside of the lifting bin. Thereafter, the push plate is rotated to drive the lifting bin and the movable plate to rotate inside the flux box body. At this time, the four movable plates will stir the flux material inside the flux box body in layers, and the four movable plates will separate the flux material inside the flux box body. Through rotation and stirring, the phenomenon of some flux materials sticking together will be greatly avoided, thereby blocking the discharge port.

[0022] The present invention prevents some of the solder from becoming damp, thereby reducing the subsequent welding effect and preventing tin frying, by providing the cooperation of structures such as the moving module and the blowing module. Hot air is stored inside the second corrugated airbag, and then the push plate is lowered, so that the connecting block drives the push rod to squeeze the second corrugated airbag, so that the hot air inside is discharged to the inside of the power module through the air outlet. The continuous rotation of the lifting bin and the continuous discharge of hot air outward from the second corrugated airbag will greatly prevent the solder from becoming partially damp, reducing the probability of tin frying.

[0023] The present invention achieves the effect of quantitative addition of flux material by arranging the coordination of structures such as the connecting module and the closing module, thereby avoiding excessive flux material addition and causing waste, and at the same time, the top of the flux box body is correspondingly sealed to ensure the dryness of the interior of the flux box body. The welding material is poured into the interior of the flux box body, and the movable plate will squeeze the first connecting pipe, so that the gas inside the first connecting pipe enters the interior of the corrugated pipe through the first corrugated airbag, so that the contact plate presses the bottom surface of the closing plate, so that the two closing plates gradually move toward each other, thereby sealing the top of the flux box body, avoiding flux material waste, and ensuring the relative dryness of the interior of the flux box body, thereby improving the subsequent welding effect;

[0024] The present invention cooperates with structures such as a pulling module and a moving module to adjust the discharge port accordingly, thereby preventing the flux material from flowing downward too quickly and causing waste of the flux material. The push plate is pressed to squeeze the bottom end of the push plate against the top of the pressure shaft, and the pressure shaft will move downward together with the rectangular groove plate and the connecting rod. The two hinged rods will cause the bottoms of the two rubber plates to move in opposite directions, so that the flux material can be discharged downward. The discharge amount of the flux material is controlled by the discharge of the two grooves, thereby preventing a large amount of flux material from being discharged downward at the same time and causing waste of the flux material. At the same time, when not in use, the bottom ends of the two rubber plates will be closed. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] As shown in Figures 1 to 12, the present invention provides a forming device for straight seam submerged arc welded steel pipes, including a flux box body 1 and a welding head 2. The middle end of the inner cavity of the flux box body 1 is movably connected to a mobile module 7, and the middle end of the mobile module 7 is internally movably connected to a power module 10. The upper and lower ends of both sides of the power module 10 are hinged with movable modules 6, and the middle part of the inner cavity of the power module 10 is movably connected to a push plate 5 that is clamped with the movable module 6. Both ends of the bottom of the mobile module 7 are fixedly connected to a connecting module 3, and the upper ends of the two connecting modules 3 are both in contact with a closing module 4 that is slidably connected to the top of the flux box body 1. The pushing plate 5 is fixedly connected to both sides of the top end of the power module 10 with a blowing module 9. The lower ends of both sides of the power module 10 are provided with an air outlet 11, and the interior of the air outlet 11 is connected to the blowing module 9. The interior of the mobile module 7 is movably connected to a pulling module 8, and the top of the pulling module 8 is in contact with the bottom of the pushing plate 5.

[0040] As shown in Figure 3, the connecting module 3 includes a first connecting tube 32 fixedly connected to the bottom of the moving module 7, the bottom of the first connecting tube 32 is fixedly connected to the first corrugated airbag 31, the top of the first corrugated airbag 31 is fixedly connected to the interference component 33, the top of the interference component 33 is in interference connection with the closing module 4, and the first corrugated airbag 31 is located on the outer wall of the flux box body 1 and is fixedly connected to the flux box body 1.

[0041] Adopting the above scheme: the downward movement of the movable module 7 will squeeze the first connecting tube 32. After the squeezing, the air inside the first connecting tube 32 will enter the interior of the resistance component 33 through the first corrugated airbag 31, and the resistance component 33 will squeeze the closing module 4, so that the closing module 4 will subsequently seal the top of the flux box body 1. The subsequent quantitative addition effect will be achieved through the movable module 7 and the closing module 4.

[0042] As shown in Figure 4, the resistance assembly 33 includes a bellows 332 fixedly connected to the top of the first corrugated airbag 31, and the top of the bellows 332 is fixedly connected to the resistance plate 331, and the bottom surface of the resistance plate 331 is fixedly connected to the end of the flux box body 1 close to the first spring telescopic cylinder 333, and the bottom end of the first spring telescopic cylinder 333 is fixedly connected to the flux box body 1. The top surface of the resistance plate 331 is provided with an oblique angle at one end close to the flux box body 1, and the closing module 4 includes a closing plate 403 movably connected to the flux box body 1, and both ends of the closing plate 403 away from the side wall of the flux box body 1 are fixedly connected to the second spring telescopic cylinder 402, and the end of the second spring telescopic cylinder 402 away from the fixed block 401 is fixedly connected to the fixed block 401 fixedly connected to the flux box body 1, and the bottom surface of the closing plate 403 is provided with an oblique angle at the end in contact with the connecting module 3.

[0043] The above solution is adopted: the gas inside the first corrugated airbag 31 enters the interior of the bellows 332, and the bellows 332 expands and moves upward, causing the resistance plate 331 to push the bottom surface of the closing plate 403 upward. The bellows 332 drives the resistance plate 331 to move upward continuously, which will cause the two closing plates 403 to gradually move toward each other, thereby sealing the top of the flux box body 1 with wind.

[0044] As shown in Figures 11 and 12, the movable module 6 includes a connecting shaft 602 connected to the inner bearing of the power module 10, a movable plate 601 is sleeved on the middle end of the outer wall of the connecting shaft 602, and spur gears 603 engaged with the push plate 5 are sleeved on both ends of the outer wall of the connecting shaft 602.

The mobile module 7 includes a mobile plate 701 movably connected to the inside of the power module 10, and slots 702 are provided at both ends of the inside of the mobile plate 701. The inside of the slot 702 is connected to the pulling module 8, and inclined blocks are provided at both ends of the top of the mobile plate 701.

[0045] Adopting the above-mentioned scheme: pushing the plate 5 downward will cause its two walls to rotate the spur gear 603, and the spur gear 603 will cause the movable plate 601 to rotate with the connecting shaft 602 as the axis. At this time, the lower end of the movable plate 601 will move outward from the inside of the power module 10, and at the same time, the limiting telescopic plate 604 will correspondingly seal the connection area between the movable plate 601 and the lifting bin 101 to prevent the flux material from falling in. The two notches 702 will separate the unloaded flux material, and the top surface of the notch 702 adopts a sloped design, which will be conducive to the downward flow of the flux material.

[0046] As shown in Figures 8 and 9, the pulling module 8 includes two rubber plates 801 fixedly connected to the inside of the moving module 7, the inner ends of the two rubber plates 801 are hinged with a hinged rod 802, and the middle parts of the top ends of the two hinged rods 802 are movably connected with a rotating shaft 803, and the outer wall of the rotating shaft 803 is sleeved with a connecting rod 804, and the bottom of the connecting rod 804 is fixedly connected with a rectangular groove plate 805, and the middle part of the rectangular groove plate 805 is fixedly connected with a pressure shaft 806, and the top of the pressure shaft 806 is in contact with the bottom of the pushing plate 5. The surface of the pressure shaft 806 at the lower end of the moving module 7 is movably sleeved with a flexible spring 807, and the upper and lower ends of the flexible spring 807 are fixedly connected to the moving module 7 and the rectangular groove plate 805 from top to bottom respectively.

[0047] The above solution is adopted: pressing the push plate 5 so that its bottom end presses the top of the pressing shaft 806, the top of the connecting rod 804 will pull the rotating shaft 803, and the two hinged rods 802 make the bottoms of the two rubber plates 801 move in opposite directions. The discharge amount of the flux material is controlled through the discharge of the two notches 702 to avoid a large amount of flux material being discharged downward at the same time, resulting in clogging of the discharge port at the bottom of the flux box body 1, thereby affecting the subsequent welding effect.

[0048] As shown in Figure 11, the blowing module 9 includes a connecting block 901 fixedly connected to the push plate 5, and the bottoms of both ends of the connecting block 901 are fixedly connected to the push rod 902, and the bottom of the push rod 902 is in contact with the second corrugated airbag 903, and the second corrugated airbag 903 is fixedly connected to the inner wall of the power module 10. The bottom end of the second corrugated airbag 903 extends through the air outlet 11 and extends to the outside of the power module 10. Hot air is regularly placed inside the second corrugated airbag 903.

[0049] The above solution is adopted: the pushing plate 5 moves downward, the connecting block 901 drives the pushing rod 902 to squeeze the second corrugated airbag 903, and the hot air inside the second corrugated airbag 903 will be discharged outward through the air outlet 11. While the movable plate 601 is used to stir the welding material inside the flux box body 1 in layers, the hot air is invaded to prevent it from being partially damp and causing tin frying.

[0050] A forming and using method of a straight seam submerged arc welded steel pipe, the forming and using method of the straight seam submerged arc welded steel pipe is:

[0051] S1. Pour welding material into the interior of the flux box body 1. The top of the movable plate 701, under the action of gravity, squeezes the first connecting tube 32. The squeezed first connecting tube 32 causes the gas inside to enter the interior of the bellows 332 through the first corrugated airbag 31. The bellows 332 expands and moves upward, causing the contact plate 331 to press against the bottom surface of the closing plate 403. As the bellows 332 drives the contact plate 331 to move upward, the two closing plates 403 gradually move toward each other, thereby sealing the top of the flux box body 1.

[0052] S2. Press the push plate 5 downward to rotate the spur gears 603 on both sides. The spur gears 603 will move the outer ends of the movable plates 601 outward. At this time, the four movable plates 601 will move outward from the interior of the lifting chamber 101 at the same time. Then, rotate the push plate 5 to drive the lifting chamber 101 and the movable plates 601 to rotate inside the flux box body 1. At this time, the four movable plates 601 will stir the flux material inside the flux box body 1 in layers.

[0053] S3. When the push plate 5 moves downward, the connecting block 901 drives the push rod 902 to squeeze the second corrugated airbag 903. At this time, the hot air inside the second corrugated airbag 903 is discharged outward through the air outlet 11. While the movable plate 601 is used to layer and stir the solder material inside the flux box body 1, the cooperation of the second corrugated airbag 903 will ensure the heat of the solder material inside the flux box body 1, preventing it from being partially damp and causing tin frying.

[0054] S4. Press the push plate 5 downward so that its bottom end presses the top of the pressing shaft 806. The pressing shaft 806 moves downward, and will move downward together with the rectangular slot plate 805 and the connecting rod 804. The top of the connecting rod 804 will pull the rotating shaft 803 downward. At this time, the two hinged rods 802 will cause the bottoms of the two rubber plates 801 to move in opposite directions, so that an opening appears at the bottom, allowing the solder material to be discharged downward. The amount of solder material discharged through the two notches 702 is controlled to avoid a large amount of solder material being discharged downward at the same time, resulting in clogging of the discharge port at the bottom of the solder box body 1, thereby affecting the subsequent welding effect.

5. The method for using the forming equipment of the straight seam submerged arc welded steel pipe according to claim 1 is characterized in that: The forming and using method of the straight seam submerged arc welded steel pipe is: S1. Pour the welding material into the interior of the flux box body (1). The top of the movable plate (701) will squeeze the first connecting tube (32) under the action of gravity. The squeezed first connecting tube (32) will allow the gas inside to enter the interior of the bellows (332) through the first corrugated airbag (31). The bellows (332) will expand and move upward, causing the resistance plate (331) to press against the bottom surface of the closing plate (403). As the bellows (332) drives the resistance plate (331) to move upward continuously, the two closing plates (403) will gradually move toward each other, thereby sealing the top of the flux box body (1). S2, pressing the push plate (5) downwards to rotate the spur gears (603) on both sides thereof, and the spur gears (603) will cause the outer ends of the movable plates (601) to move outwards, and at this time, the four movable plates (601) will simultaneously move outwards from the inside of the lifting bin (101), and then the push plate (5) will be rotated to drive the lifting bin (101) and the movable plates (601) to rotate inside the flux box body (1), and at this time, the four movable plates (601) will stir the flux material inside the flux box body (1) in layers; S3. When the push plate (5) moves downward, the connection block (901) drives the push rod (902) to squeeze the second corrugated airbag (903). At this time, the hot air inside the second corrugated airbag (903) will be discharged outward through the air outlet (11). While the movable plate (601) is used to stir the welding material inside the welding box body (1) in layers, the cooperation of the second corrugated airbag (903) will ensure the heat of the welding material inside the welding box body (1), thereby preventing the welding material from being partially damp and causing tin frying; S4, press the push plate (5) downward so that its bottom end presses the top of the pressing shaft (806), and the pressing shaft (806) moves downward, and together with the rectangular groove plate (805) and the connecting rod (804), it moves upward. When the connecting rod (804) moves downward, the top end of the connecting rod (804) will pull the rotating shaft (803) downward, and at this time, the two hinged rods (802) will cause the bottoms of the two rubber plates (801) to move in opposite directions, so that an opening appears at the bottom, allowing the solder material to be discharged downward. The amount of solder material discharged through the two notches (702) is controlled to prevent a large amount of solder material from being discharged downward at the same time, resulting in clogging of the discharge port at the bottom of the solder box body (1), thereby affecting the subsequent welding effect.
