Description

Technical Field

[0001] The present invention belongs to the technical field of water-cooling anti-deformation, and in particular is a double-sided fire bar precise positioning water-cooling anti-deformation device. Background Art

[0002] A double-sided welding structure in the prior art is specifically two rows of opposing gun nozzles. During welding, the two rows of opposing gun nozzles will weld the weldment between them, but in this process the gun nozzle on one side will heat the gun nozzle on the opposite side, causing it to deform after heating, thereby reducing its service life. In order to solve this problem, a water-cooling pipe for passing cooling water is provided under the gun nozzle to achieve water-cooling and anti-deformation. Moreover, since the water-cooling pipe is fixedly connected to the bottom of the gun nozzle, the direction of the gun nozzle can also be limited, so that the flame ejected from the gun nozzle can be accurately positioned.

[0003] A patent application with publication number CN216503069U discloses a water-cooling pipe for copper blocks used for template welding, including a base, a water-cooling pipe, an adjustment bracket and a water-cooled copper block, wherein connecting sleeves are evenly arranged on the right side of the top of the base, the pipe bracket is arranged on the left side of the top of the base, and a water-cooling pipe is arranged on the top of the pipe bracket. The pipe enables the copper blocks to fit into the outer wall of the template at different angles, and the copper blocks can be interlocked using slots and blocks to form an integral structure of the copper blocks, which facilitates the orderly fitting of the copper blocks to the outer wall of the template and improves the cooling effect.

[0004] There are still some problems in the actual application of the above scheme. When the water-cooling pipe is used to water-cool the two rows of opposing spraying gun nozzles, the cooling water will contact part of the outer wall of the gun nozzle. After long-term use, scale and dirt will be generated at the contact point between the gun nozzle and the water flow. These dirt will not only reduce the heat dissipation efficiency, but also cause corrosion to the surface of the gun nozzle. Moreover, this part of the gun nozzle is located inside the water-cooling anti-deformation device, which may be relatively difficult to maintain and service.

[0005] To this end, the present invention provides a double-sided fire bar precise positioning water-cooling anti-deformation device. Summary of the invention

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0021] like Figures 1 to 10As shown, a double-sided fire row precise positioning water-cooling anti-deformation device according to an embodiment of the present invention comprises a base frame 1, a plurality of gas pipes 2 are arranged at the upper end of the base frame 1, a gas pipe 21 is arranged at one end of the gas pipe 2, an auxiliary pipe 3 is arranged at the upper end of the gas pipe 21, a gun nozzle 5 is arranged at one end of the gas pipe 21, a positioning strip 4 is arranged on the surface of the gun nozzle 5, a water-cooling structure 6 is arranged inside the positioning strip 4, and an adjustment structure 7 is arranged at the lower end of the water-cooling structure 6; the water-cooling structure 6 comprises: a cooling frame 61, the cooling frame 61 is arranged at the lower end of the gun nozzle 5; a fixed pipe 62, the fixed pipe 62 is arranged at the side end of the cooling frame 61; the adjustment structure 7 comprises: a movable pipe 720, the movable pipe 720 is arranged inside the cooling frame 61, and the movable pipe 720 slides on the surface of the fixed pipe 62; a sealing Sealing plate 724, sealing plate 724 is rotatably connected to the interior of cooling frame 61; liquid storage tank 703, the interior of liquid storage tank 703 is filled with descaling liquid, liquid storage tank 703 is arranged at the lower end of cooling frame 61, one end of liquid storage tank 703 is provided with first liquid passage 701; residue frame 711, residue frame 711 is arranged at one end of liquid storage tank 703, one end of residue frame 711 is provided with second liquid passage 712; adjusting frame 713, one of two adjusting frames 713 is arranged at one end of first liquid passage 701, and the other is arranged at one end of second liquid passage 712, and adjusting frame 713 is communicated with cooling frame 61; first slide plate 730, first slide plate 730 is slidably connected to the interior of adjusting frame 713, one end of first slide plate 730 is slidably connected to second slide plate 731.

[0022] Specifically, the solution is a double-sided fire row precise positioning water-cooling anti-deformation device, which is used to cool the working gun nozzle 5. When the gun nozzle 5 is in use, gas is first introduced into the gas pipe 2, and then the gas is converted into flames, which are ejected from the gun nozzle 5 through the gas pipe 21, so as to weld the first welding part 8 and the second welding part 9. In order to improve the quality of the weld, two rows of gun nozzles 5 are provided, and the welding ports of the two rows of gun nozzles 5 are opposite. However, when in use, the flame ejected from the gun nozzle 5 on one side will affect the gun nozzle 5 on the other side, thereby shortening the use of the gun nozzle 5. Lifespan, at this time, by arranging positioning strips 4 on the surface of a row of gun nozzles 5 and arranging a water cooling structure 6 inside the positioning strips 4, the gun nozzles 5 can be cooled to reduce the impact of flames. When water cooling is required, cooling water is introduced into the interior of the fixed pipe 62, and the cooling water will flow inside the cooling frame 61, and in the process of flowing, the cooling water will absorb the heat generated by the gun nozzles 5 through the thermal conductivity of water, and take the heat away through the circulating flow, thereby achieving heat dissipation, and after the welding work is completed, the gun nozzle 5 will stop working.

[0023] After long-term use, silicates in the cooling water are likely to form silica scale when combined with calcium and magnesium ions in hard water, and are deposited on the outer wall of the nozzle 5. At this time, the cooling water injection of the fixed pipe 62 is cut off, and the movable pipe 720 is started. At this time, the movable pipe 720 will move toward one end of the fixed pipe 62, and in the process of moving, the sealing plate 724 is started, and the sealing plate 724 will rotate. When the end of the movable pipe 720 moves to be flush with the end of the fixed pipe 62, the sealing plate 724 will also rotate to block the passage between the fixed pipe 62 and the cooling frame 61. At this time, the first slide 730 and the second slide 731 are started, and the two will move in a direction away from each other, thereby opening the adjustment frame 713. At this time, the descaling liquid inside the liquid storage tank 703 will also flow out from the inside of the liquid storage tank 703. The descaling liquid can clean the silica scale attached to the outer wall of the nozzle 5 and enter the interior of the cooling frame 61 through the first liquid passage 701. When the sealing plate 724 has blocked the fixed pipe 62, the descaling liquid will flow in the direction of the cooling water flow, thereby cleaning and preventing the outer wall of the gun nozzle 5 from being contaminated, and the cleaned dirt and descaling liquid will not flow out of the cooling frame 61, but will enter the interior of the residue frame 711 through the second liquid passing pipe 712 for collection, and when welding work is needed again, the movable pipeline 720 is started again to continue to connect the fixed pipe 62 with the cooling frame 61, and the adjustment frame 713 will also be closed, so as not to affect the cooling of the gun nozzle 5. By setting the adjustment structure 7, the descaling liquid can be introduced into the interior of the cooling frame 61 when the gun nozzle 5 is not working, and due to the closure of the sealing plate 724, the flow range of the descaling liquid is limited to the position in contact with the gun nozzle 5 in the cooling frame 61, thereby cleaning and preventing the outer wall of the gun nozzle 5 from being contaminated, and the cleaned dirt and descaling liquid will also be collected separately, so as not to affect the subsequent cooling.

[0024] like Figures 1 to 10 As shown, the adjustment structure 7 also includes: a rotating shaft 722, which is rotatably connected to the inside of the cooling frame 61, and a sealing plate 724 is arranged on the surface of the rotating shaft 722; a rotating gear 723, which is arranged at one end of the rotating shaft 722; a rack 725, which is slidably connected to the inside of the cooling frame 61, and the rotating gear 723 is meshed with the rack 725; a ring 721, which is arranged on the surface of the movable pipe 720, and the ring 721 is connected to the rack 725; a first connecting rod 704, which is arranged in the inside of the adjustment frame 713, and the first slide 730 and the second slide 731 both slide on the surface of the first connecting rod 704; a second connecting rod 705, which is arranged in the inside of the adjustment frame 713, and the first slide 730 and the second slide 731 are both threadedly connected to the second connecting rod 705.

[0025] Specifically, when the movable pipe 720 moves toward one end of the fixed pipe 62, the movable pipe 720 will drive the rack 725 to move through the ring 721, and during the movement, the rack 725 will drive the rotating gear 723 to rotate, and at this time the rotating gear 723 will drive the sealing plate 724 to rotate through the rotating shaft 722, and finally block the channel between the fixed pipe 62 and the cooling frame 61, and then rotate the second connecting rod 705. Since the first slide 730 and the second slide 731 are threadedly connected to the second connecting rod 705, and the other ends of the first slide 730 and the second slide 731 slide on the surface of the first connecting rod 704, the two will move away from each other at this time, thereby opening the adjustment frame 713.

[0026] like Figures 1 to 6 As shown, a pressurized water pipe 709 is provided inside the first liquid pipe 701, and the inner diameter of the pressurized water pipe 709 gradually decreases toward the end away from the liquid storage tank 703. The end of the first liquid pipe 701 away from the liquid storage tank 703 is slidably connected to a ball valve 710, and one end of the ball valve 710 is connected to a sliding rod 717.

[0027] Specifically, by setting the ball valve 710, in the initial state, the ball valve 710 will block one end of the pressure water pipe 709, thereby preventing the descaling liquid from flowing out. When the descaling liquid needs to be introduced, the sliding rod 717 is started, and the sliding rod 717 will drive the ball valve 710 to move away from the pressure water pipe 709, thereby allowing the descaling liquid to flow out. Moreover, since the inner diameter of the pressure water pipe 709 gradually decreases, the flow rate of the descaling liquid inside will increase at this time, thereby increasing the descaling speed.

[0028] like Figures 1 to 9 As shown, one end of the adjustment frame 713 is slidably connected to a movable block 719, one end of the second connecting rod 705 is provided with a screw rod 718, and the screw rod 718 is threadedly connected to the movable block 719, the upper end of the movable block 719 is provided with a second connecting arm 726, and the second connecting arm 726 is connected to the ring 721, the lower end of the movable block 719 is provided with a first connecting arm 708, and one end of the first connecting arm 708 is connected to the sliding rod 717.

[0029] Specifically, by setting the movable block 719, when the nozzle 5 stops working, the movable block 719 is started, and the movable block 719 will move in the direction away from the adjusting frame 713, and during the movement, the movable block 719 will drive the screw 718 to rotate, thereby causing the second connecting rod 705 to rotate, and the first slide plate 730 and the second slide plate 731 will move in the directions away from each other, and at this time, the second connecting arm 726 will also drive the ring 721 to move, thereby blocking the passage between the fixed pipe 62 and the cooling frame 61, and the first connecting arm 708 will also cause the ball valve 710 to move in the direction away from the water pressure pipe 709, thereby realizing the simultaneous execution of multiple steps.

[0030] like Figure 1 to Figure 2 As shown, a baffle 702 is provided at the lower end of the positioning bar 4 .

[0031] Specifically, by providing the baffle 702, when the gun nozzle 5 is working, the baffle 702 can reduce the damage of the flame to the liquid storage tank 703 and the surrounding structures.

[0032] like Figures 1 to 4 As shown, a reset rubber block 727 is provided inside the cooling frame 61 , and the reset rubber block 727 is in contact with the second connecting arm 726 .

[0033] Specifically, by setting the reset rubber block 727, the reset rubber block 727 will crack when it contacts the second connecting arm 726, so that the second connecting arm 726 can move. When the reset rubber block 727 does not contact the second connecting arm 726, the reset rubber block 727 inside the cooling frame 61 will abut, thereby sealing the cooling frame 61 from the outside and preventing the cooling water inside the cooling frame 61 from leaking out.

[0034] like Figures 1 to 8 As shown, a discharge pipe 706 is provided at one end of the first liquid passage pipe 701, a slot 728 is opened between the discharge pipe 706 and the first liquid passage pipe 701, a connecting rod 729 is provided at one end of the sliding rod 717, and both the connecting rod 729 and the sliding rod 717 slide inside the slot 728, and the connecting rod 729 is connected to the first connecting arm 708.

[0035] Specifically, by setting the discharge pipe 706, when the sliding rod 717 drives the ball valve 710 to move so that the descaling liquid enters the interior of the cooling frame 61, the sliding rod 717 at this time will block the slot 728, so that the descaling liquid will not enter the interior of the discharge pipe 706. Subsequently, when the descaling is completed and the ball valve 710 is reset, the sliding rod 717 is no longer inside the slot 728, and since the diameter of the connecting rod 729 is smaller than the sliding rod 717, the excess descaling liquid will enter the interior of the discharge pipe 706 through the slot 728, thereby being discharged from the first liquid passage 701. Embodiment 2

[0036] like Figures 3 to 10 As shown, in contrast to Example 1, another embodiment of the present invention is that a scraping frame 707 is provided on the surface of the sliding rod 717 , a scraping bar 714 is provided on the surface of the scraping frame 707 , and the scraping bar 714 is in contact with the inner wall of the first liquid passage 701 .

[0037] Specifically, by setting the scraper bar 714, when the sliding rod 717 drives the ball valve 710 to move, the scraper frame 707 located on the surface of the sliding rod 717 will also move, and since the scraper bar 714 is provided on the surface of the scraper frame 707, the scraper bar 714 will also clean the inner wall of the first liquid passage 701 to avoid blockage.

[0038] like Figures 9 and 10 As shown, an adjustable filter 715 is provided inside the scraping frame 707.

[0039] Specifically, by setting the regulating filter 715, when the descaling liquid is passed into the interior of the cooling frame 61, the regulating filter 715 inside the scraping frame 707 will filter out the impurities inside the descaling liquid, thereby avoiding the accumulation of impurities inside the cooling frame 61.

[0040] like Figures 9 and 10 As shown, the adjustment filter screen 715 inside the scraping frame 707 is semicircular, and a fixed filter screen 716 is provided inside the first liquid passage 701, and the fixed filter screen 716 is also semicircular.

[0041] Specifically, by setting a fixed filter 716, when the sliding rod 717 drives the ball valve 710 to move, the scraping frame 707 will drive the adjustable filter 715 to move flush with the fixed filter 716, thereby performing the filtering work. After the descaling liquid is introduced, the ball valve 710 is reset, and the adjustable filter 715 and the fixed filter 716 will be separated. At this time, impurities can be discharged by simply flushing clean water into the discharge pipe 706.

[0042] Working principle: When water cooling is required, cooling water is introduced into the interior of the fixed pipe 62, and the cooling water will flow inside the cooling frame 61. During the flow, the cooling water will absorb the heat generated by the nozzle 5 through the thermal conductivity of the water, and take the heat away through the circulation flow, thereby achieving heat dissipation. After the welding work is completed, the nozzle 5 will stop working, at this time, the cooling water injection into the fixed pipe 62 is cut off, and the movable block 719 is started. The movable block 719 will move in the direction away from the adjustment frame 713, and during the movement, the movable block 719 will bring The movable screw rod 718 rotates, thereby causing the second connecting rod 705 to rotate. Since the first slide plate 730 and the second slide plate 731 are both threadedly connected to the second connecting rod 705, and the other ends of the first slide plate 730 and the second slide plate 731 slide on the surface of the first connecting rod 704, the two slide plates will move away from each other at this time, thereby opening the adjustment frame 713, and at this time, the second connecting arm 726 will also drive the ring 721 to move, and the ring 721 will drive the rack 725 to move, and during the movement, the rack 725 will drive the rotating gear 723 rotates, and at this time, the rotating gear 723 will drive the sealing plate 724 to rotate through the rotating shaft 722. When the end of the movable pipe 720 moves to be flush with the end of the fixed pipe 62, the sealing plate 724 will also rotate to block the passage between the fixed pipe 62 and the cooling frame 61. At the same time, the ball valve 710 will also be moved away from the water pressure pipe 709 through the first connecting arm 708, so that the descaling liquid will pass out. Since the inner diameter of the water pressure pipe 709 gradually decreases, the flow rate of the descaling liquid inside will increase and enter the cooling frame 61. Internally, since the sealing plate 724 has blocked the fixed tube 62 at this time, the descaling liquid will flow in the direction of the cooling water flow, thereby removing and preventing dirt on the outer wall of the gun nozzle 5, and the removed dirt and descaling liquid will not flow out of the cooling frame 61, but enter the interior of the residue frame 711 through the second liquid pipe 712 for collection, and when welding work is needed again, the movable pipeline 720 can be started again to continue to connect the fixed tube 62 with the cooling frame 61, and the adjustment frame 713 will also be closed, so as not to affect the cooling of the gun nozzle 5.

[0043] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
