[0032] In the related art, when water pipes are produced, the flux backing is difficult to be stabilized in the welding position due to its ductility, and a gap is easily generated between the flux backing and the welding position, making the weld prone to defects such as welding slag and pores, resulting in poor actual welding effect of the steel pipe.
[0033] In order to solve the technical problem, the utility model provides a flux pad.
[0034] See also Figure 1In one embodiment of the utility model, the flux pad includes a base 100, a flux pad body 300, a movable plate 400, a lifting mechanism 500 and a control mechanism 600. A connecting assembly 200 extending vertically is installed on the top of the base 100; the flux pad body 300 is installed on one side of the base 100 through the connecting assembly 200; a flux groove 301 is formed on the side of the flux pad body 300 away from the base 100; the movable plate 400 is arranged between the base 100 and the flux pad The movable plate 400 is slidably installed on the connecting assembly 200 along the vertical direction between the main body 300; the lifting mechanism 500 is installed on the base 100, and the lifting end of the lifting mechanism 500 is connected to the movable plate 400. The lifting mechanism 500 is used to drive the movable plate 400 to rise and press against the side of the flux pad body 300 facing the base 100, or drive the movable plate 400 to descend to move away from the side of the flux pad body 300 facing the base 100; the control mechanism 600 is electrically connected to the lifting mechanism 500.
[0035] It should be noted that the interaction between the control mechanism 600 and the lifting mechanism 500 is a prior art.
[0036] It should be understood that the movable plate 400 extends along the length direction of the flux pad body 300; since the flux pad body 300 is ductile, when the control mechanism 600 controls the lifting mechanism 500 to press the movable plate 400 against the side of the flux pad body 300 facing the base 100, the movable plate 400 presses the flux pad body 300 against the steel pipe at the welding position of the steel pipe, thereby reducing the gap between the flux pad body 300 and the welding position of the steel pipe, so that the welding pad body is stabilized at the welding position of the steel pipe; after completing the welding process at the current welding position, the control mechanism 600 controls the lifting mechanism 500 to move the movable plate 400 downward, thereby releasing the flux pad body 300. Specifically, the base 100 and the connecting assembly 200 provide a stable support for the flux pad body 300; the movable plate 400 can be moved between the flux pad body 300 and the base 100 according to the needs of welding to change the tightness between the flux pad body 300 and the welding position of the steel pipe to improve the welding quality; the control mechanism 600 is electrically connected to the lifting mechanism 500 to control the rise and fall of the movable plate 400. Before welding, the control mechanism 600 raises the movable plate 400 to press the flux pad body 300 to the welding position; after completing the current welding, the control mechanism 600 drives the movable plate 400 to descend to release the flux pad body 300, so as to facilitate the movement and adjustment of the flux pad.
[0037] In the technical solution provided by the utility model, the position of the movable plate 400 is adjusted by the lifting mechanism 500, so that the movable plate 400 can press the flux pad body 300 firmly against the welding position on the steel pipe when it is pressed against the side of the flux pad body 300 facing the base 100, thereby reducing the gap between the flux pad and the welding position of the steel pipe, so that the flux can fit tightly to the weld, thereby improving the protection effect of the steel pipe weld, improving the quality of the steel pipe weld, and then improving the one-time welding pass rate of the steel pipe, and reducing the adverse effect of the ductility of the flux pad body 300 on the welding effect, so that the weld is not easy to produce defects such as welding slag and pores, thereby improving the pipe welding quality and effect of the water pipe, and improving the product yield of the water pipe.
[0038] There are many forms of implementation of the connection assembly 200. In an embodiment of the utility model, the connection assembly 200 includes a plurality of vertical rods 210, which are arranged at intervals along the periphery of the base 100; one end of the vertical rod 210 is connected to the top of the base 100, and the other end of the vertical rod 210 is connected to the flux pad body 300. By arranging a plurality of vertical rods 210 along the periphery of the base 100 at the top of the base 100, the structural stability of the entire flux pad is enhanced. Each vertical rod 210 extends from the top of the base 100 to the flux pad body 300, forming a multi-point support, which can effectively disperse the pressing force when the welding pad body is pressed against the welding position of the steel pipe, and reduce the structural deformation of the flux pad body 300 caused by its ductility; the plurality of vertical rods 210 not only provide physical support, but also help to maintain the stability and safety of the entire equipment during the welding process.
[0039] Specifically, see Figure 2 In an embodiment of the utility model, a plurality of vertical holes 401 are formed on the movable plate 400 , the number of the vertical holes 401 is consistent with the number of the vertical rods 210 and they are arranged in one-to-one correspondence, each vertical rod 210 is inserted into the corresponding vertical hole 401 , and the movable plate 400 is slidably connected to the vertical rod 210 through the vertical hole 401 . Since the vertical rod 210 plays a guiding role in the vertical hole 401, the stability and accuracy of the movable plate 400 during vertical movement can be ensured, and the movable plate 400 can be prevented from affecting the force of the flux pad body 300 due to offset or tilt. In addition, the cooperation between the vertical hole 401 and the vertical rod 210 makes the connection between the movable plate 400 and the connecting assembly 200 more concise and clear. During installation and maintenance, it is only necessary to insert the vertical rod 210 into the corresponding vertical hole 401, which simplifies the assembly and disassembly process of the movable plate 400 and improves the maintenance efficiency and operational convenience of the equipment; and the vertical hole 401 of the movable plate 400 also limits the vertical rod 210, which can reduce the vibration and displacement of the flux pad body 300 during welding operation and ensure the continuity and consistency of the welding process.
[0040] More specifically, in the embodiment of the utility model, the flux pad also includes an elastic component 700, which is sleeved outside the connecting component 200 and is disposed between the movable plate 400 and the flux pad body 300. The elastic component 700 forms a continuous elastic force between the movable plate 400 and the flux pad body 300. When the movable plate 400 rises and presses against the flux pad body 300, the elastic component 700 will be further compressed to generate a pre-tightening force, further reducing the gap between the flux pad body 300 and the steel pipe welding position, ensuring that the flux pad body 300 is firmly welded to the steel pipe, thereby effectively reducing the generation of welding defects (such as pores and slag inclusions), enhancing welding quality and appearance quality, and improving the mechanical properties of the welded joint. In addition, the elastic force of the elastic component 700 can automatically compensate for the gap between the flux pad body 300 and the steel pipe welding position, so that the flux pad body 300 can be quickly stabilized at the welding position without multiple adjustments, thereby improving the welding efficiency of the steel pipe. Furthermore, the elastic component 700 can also form a buffer between the movable plate 400 and the flux pad body 300 to prevent the movable plate 400 from directly contacting and damaging the flux pad body 300, thereby extending the service life of the flux pad body 300, reducing the replacement frequency, and lowering the maintenance cost.
[0041] See also Figure 3 In the embodiment of the utility model, the elastic component 700 includes a plurality of springs 710, the number of the springs 710 is consistent with the number of the vertical rods 210 and they are arranged one by one, and each spring 710 is sleeved outside the corresponding vertical rod 210. Specifically, each spring 710 is sleeved outside the corresponding vertical rod 210, so that there are a plurality of independent elastic supports between the movable plate 400 and the flux pad body 300, and the number of supporting points of the elastic component 700 on the flux pad body 300 is increased, so that the flux pad body 300 is subjected to more uniform force when the movable plate 400 is pressed against the welding position of the steel pipe, ensuring the consistency and quality of the welding seam, thereby improving the welding effect of the water pipe.
[0042] There are many forms of implementation of the lifting mechanism 500. In an embodiment of the present utility model, the lifting mechanism 500 includes a plurality of lifting driving members 510, which are installed at intervals on the base 100. The telescopic shafts of the lifting driving members 510 form lifting ends, and the plurality of lifting driving members 510 are electrically connected to the control mechanism 600. The plurality of driving members ensure that the movable plate 400 can evenly apply force when it is pressed against the flux pad body 300, thereby preventing the flux pad body 300 from being deformed or loosely fixed due to uneven force. In addition, the design of the plurality of lifting driving members 510 ensures that the flux pad body 300 is supported at different positions, thereby reducing the adverse effects of the ductility of the flux pad body 300 on the steel pipe welding process, and improving the pipe manufacturing efficiency and quality of the water pipe.
[0043] It should be noted that the lifting drive member 510 can be a HOB type cylinder in the prior art.
[0044] It should be understood that the multiple lifting drive members 510 are arranged at intervals along the length direction of the flux pad body 300, and the connection positions of the multiple lifting drive members 510 and the flux pad body 300 can be determined according to the material and ductility of the flux pad body 300 itself. For example, when the ductility of the flux pad body 300 is good, in order to ensure that the movable plate 400 is pressed against the flux pad body 300, the flux pad body 300 can be effectively pressed against the welding position of the steel pipe, the telescopic axis of one of the multiple lifting drive members 510 is connected to the geometric center of the movable plate 400.
[0045] In an embodiment of the utility model, the control mechanism 600 includes a mounting structure 610, a trigger structure 620, a sensing module 630 and a control module. A mounting port 402 is formed on the movable plate 400, and the mounting structure 610 is mounted on the mounting port 402. A slot 640 facing the flux pad body 300 and having a slot 641 formed on the side of the mounting structure 610 away from the base 100, wherein the sensing module 630 is mounted in the slot 640; a trigger structure 620 is installed on the side of the flux pad body 300 facing the base 100, and the trigger structure 620 is arranged at a position corresponding to the slot 641; the sensing module 630 and the lifting mechanism 500 are both electrically connected to the control module, and the sensing module 630 is used to sense the trigger structure 620. The slot 640 on the mounting structure 610 corresponds to the trigger structure 620 installed on the flux pad body 300. When the movable plate 400 rises through the lifting mechanism 500, the trigger structure 620 enters the detection range of the sensing module 630, ensuring that the sensing module 630 can accurately sense the trigger structure 620, so that the sensing module 630 can accurately interact with the trigger structure 620, and provide reliable signal feedback for the control module; the trigger structure 620 installed on the side of the flux pad body 300 facing the base 100 is located at the position corresponding to the slot 641.
[0046] It should be noted that the interaction between the sensing module 630, the control module and the driving mechanism is a prior art.
[0047] It should be understood that the sensing module 630 may be a pressure sensor or a distance sensor.
[0048] Specifically, see Figure 4In the embodiment of the utility model, the mounting structure 610 includes a bracket 611, a bottom plate 612 and a plurality of guide plates 613. The bracket 611 is mounted on the bottom plate 612; the plurality of guide plates 613 are all mounted in the mounting opening 402, the plurality of guide plates 613 are arranged along the periphery of the bottom plate 612, and the bottom plate 612 and the plurality of guide plates 613 are arranged to form a slot 640; the sensing module 630 is mounted on the bracket 611. The guide plate 613 limits and guides the process of the trigger structure 620 extending into the slot 640, thereby increasing the interaction accuracy between the trigger structure 620 and the sensing module 630, and the slot 640 formed by the bottom plate 612 and the plurality of guide plates 613 can also protect the sensing module 630, preventing the sensing module 630 from being damaged by external impact.
[0049] More specifically, in the embodiment of the utility model, the bottom plate 612 is formed with a wiring groove 650. The wiring groove 650 has a first opening end and a second opening end, the first opening end is opened at one side of the bottom plate 612 below the movable plate 400, and the second opening end is opened at one side of the bottom plate 612 in the slot 640. The wiring groove 650 is used to accommodate the circuit of the sensing module 630 to avoid interference between the circuit of the sensing module 630 and the displacement path of the movable plate 400, and the wiring groove 650 is also convenient for managing and storing the circuit of the sensing module 630, and can also prevent the circuit of the sensing module 630 from being damaged.
[0050] In the embodiment of the present invention, the trigger structure 620 includes a trigger member and a buffer layer, one end of the trigger member is connected to the side of the flux pad body 300 facing the base 100, and the other end of the trigger member is connected to the buffer layer.
[0051] It should be noted that the sensing module 630 is a pressure sensor in the prior art; the buffer layer is a flexible component, such as rubber in the prior art; and the trigger component is a rigid component, such as a metal block in the prior art.
[0052] It should be understood that when the control module controls the lifting mechanism 500 to drive the movable plate 400 to rise, when the movable plate 400 is pressed against the side of the flux pad body 300 facing the base 100, the trigger member extends into the slot 640, and the buffer layer at one end of the trigger member squeezes the sensing module 630, and the sensing module 630 generates an electrical signal. The control module controls the lifting mechanism 500 to stop working according to the electrical signal of the sensing module 630. After the control module receives the reset signal, the control module controls the lifting mechanism 500 to retract the telescopic shaft to make the movable plate 400 descend to release the flux pad body 300.
[0053] As an optional implementation manner of this embodiment, in order to further improve the accuracy of the movable plate 400 when it is pressed against the flux pad body 300, and further reduce the gap between the flux pad body 300 and the steel pipe when it is pressed against the welding position of the steel pipe, there are multiple sensing modules 630, and the multiple sensing modules 630 are arranged at intervals along the length direction of the flux pad body 300. There are multiple triggering members, and the number of triggering members is consistent with the number of sensing modules 630 and is arranged one-to-one.
