[0032] The embodiment of the utility model provides a wind shield and a welding gun assembly for outdoor pipeline welding. The spacing between the outer walls of the wind shield and the pipeline is not too large, wind interference is eliminated, and the air is effectively isolated from the molten pool, so that the arc starting is stable and the weld quality is guaranteed.
[0033] Combine the following Figure 1-Figure 6 The technical solution provided by the utility model is described in more detail.
[0034] Embodiment 1:
[0035] The utility model provides a wind shield, comprising a wind shield body 1, a movable plate 2 and an elastic member 3, wherein: the wind shield body 1 is at least covered outside the welding end of the welding gun 8, and the movable plate 2 is slidably connected to the side of the wind shield body 1; the opposite ends of the elastic member 3 are respectively connected to the wind shield body 1 and the movable plate 2, and the movable plate 2 has an arc-shaped end 21. When the elastic member 3 is in the original length state, the arc-shaped end 21 protrudes from the arc-shaped lower edge 13 of the wind shield body 1. The arc-shaped end 21 can slide relative to the wind shield body 1 along its own radial direction when the welding gun 8 is fed, and then always abuts against the outer wall of the pipeline.
[0036] Among them, see Figure 4 As shown, the lower end of the air hood body 1 is an arc-shaped lower edge 13, which can better fit the surface of the pipeline.
[0037] The elastic member 3 can be a spring, which is used to make the arc-shaped end 21 slide relative to the wind shield body 1 along its own radial direction when the welding gun 8 is fed, so as to always abut against the outer wall of the pipeline; and when the wind shield is separated from the pipeline, the spring is used to reset the movable plate 2.
[0038] The wind shield of this embodiment has a wind shield body 1 which is arranged outside the welding end of the welding gun 8. The arc-shaped lower edge 13 of the wind shield body 1 and the arc-shaped end 21 of the movable plate 2 are both arc-shaped structures, which can better fit the surface of the pipeline, thereby protecting the welding gun 8 in a relatively closed space (no need to be completely sealed). As the welding wire becomes shorter during welding, the elastic member 3 enables the movable plate 2 to extend and retract up and down, and the arc-shaped end 21 of the movable plate 2 can always abut against the pipeline without affecting normal welding.
[0039] The spacing between the outer walls of the wind shield pipe is not too large, which eliminates wind interference, effectively isolates the air from the molten pool, stabilizes the arc starting, ensures the quality of the weld, and has the characteristics of small size and light weight.
[0040] As an alternative embodiment, see Figure 1 and Figure 3 As shown, a guide column 11 is provided on the air hood body 1, and an adjustment hole 22 is provided on the movable plate 2. The adjustment hole 22 is arranged radially along the arc-shaped end 21. The guide column 11 extends into the adjustment hole 22 and can slide along the adjustment hole 22.
[0041] The above structure enables the movable plate 2 and the wind shield body 1 to slide stably along the radial direction of the arc-shaped end 21, thereby ensuring the stability of the structure.
[0042] In the wind shield of this embodiment, as the welding wire becomes shorter during welding, the arc-shaped end 21 of the movable plate 2 presses on the pipe, and the elastic member 3 connected between the movable plate 2 and the lower end of the wind shield body 1 is compressed. With the cooperation of the guide column 11 and the adjustment hole 22, the movable plate 2 slides upward, thereby not hindering the welding wire from contacting the weld.
[0043] As an alternative embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, two ends of the elastic member 3 are fixedly connected to the lower end of the air hood body 1 and the upper end of the movable plate 2 respectively.
[0044] See also Figure 3 As shown, as the welding wire is gradually shortened, the arc end 21 abuts against the outer wall of the pipe, and the elastic member 3 is gradually stretched. When welding is completed, the wind shield is separated from the pipe, and the elastic member 3 resets the movable plate 2.
[0045] As an alternative embodiment, see Figure 4 As shown, the wind shield body 1 is a trapezoidal shield, see Figure 1 and Figure 2 As shown, the movable plate 2 is slidably connected to the opposite sides of the wind shield body 1, see Figure 1 and Figure 2 As shown, a mounting plate 5 is fixed to the other side or both sides of the wind shield body 1, and a mounting shell is formed by the mounting plate 5 and the side wall of the wind shield body 1, and an observation mirror 4 is fixed in the mounting shell.
[0046] The user can observe the welding situation in the wind shield through the observation mirror 4, which is convenient for the smooth progress of the welding work.
[0047] As an alternative embodiment, see Figure 2 As shown, one side of the mounting shell is an open structure 501, and the observation mirror 4 can be inserted into the mounting shell through the open structure 501. The opposite sides of the open structure 501 are provided with limiting holes 502 for the fixing parts to pass through.
[0048] See also Figure 2 The observation mirror 4 can be installed in the containment shell by the open structure 501, that is, the observation mirror 4 is clamped between the mounting plate 5 and the side wall of the wind shield body 1, and the fixing member can be a screw, etc. The fixing member passes through the limit hole 502, which can prevent the observation mirror 4 from being separated from the installation shell. If the observation mirror 4 needs to be replaced in time, it only needs to remove the screw (fixing member), which can greatly save time and cost.
[0049] The molten pool can be observed through the observation mirror 4. When the observation mirror 4 is made of black glass, the arc light can be filtered out, and the welder does not need to wear a welding cap, which can reduce the labor intensity of the welder and is easy to use.
[0050] As an alternative embodiment, see Figure 2As shown, a first bent plate is fixed to the upper end of the movable plate 2, a second bent plate 51 is fixed to the lower end of the mounting plate 5, and both ends of the elastic member 3 are respectively fixedly connected to the first bent plate and the second bent plate 51. The first bent plate and the movable plate 2 are an integrally formed structure, and the second bent plate 51 and the mounting plate 5 are an integrally formed structure, and the above structure facilitates the fixing of the elastic member 3.
[0051] As an optional implementation, participate Figure 1 and Figure 4 As shown, the hood body 1 is provided with a smoke exhaust hole 101, and the number of the smoke exhaust hole 101 is one or more than two, which are used to exhaust the smoke generated during the welding process.
[0052] As an alternative embodiment, see Figure 2 As shown, the arc-shaped end 21 and / or the lower edge of the wind shield body 1 are provided with fixing holes 6, and the fixing holes 6 are used to fix the windproof curtain.
[0053] The fixing hole 6 may be a threaded hole, and the windproof curtain may be fixedly connected to the windproof cover by screws or bolts.
[0054] In this embodiment, the arc-shaped end 21 and the lower edge of one side of the wind shield body 1 for installing the observation mirror 4 are provided with fixing holes 6, that is, the fixing holes 6 are arranged at the lower ends of the four sides of the wind shield. In this way, the windproof curtain can be blocked by the part of the bottom of the wind shield that cannot completely fit the pipeline, thereby enhancing the windproof effect. When the welding gun 8 is used for welding in a windless environment, the windshield can be removed or the windproof cloth can be rolled up.
[0055] As an alternative embodiment, see Figure 1 and Figure 5 , Figure 6 As shown, the wind shield also includes a connecting plate 7, see Figure 5 As shown, the upper end of the hood body 1 is provided with a through hole 12, the connecting plate 7 is fixed to the upper end of the hood body 1, and a bayonet 71 connected to the through hole 12 is formed on the connecting plate 7; one side of the connecting plate 7 is fixed to the hood body 1, and an adjustment opening 72 is formed on the other side of the connecting plate 7, and a locking member 73 passes through opposite sides of the adjustment opening 72 to adjust the size of the bayonet 71. The inner diameter of the through hole 12 is not less than the outer diameter of the welding gun 8, so that the welding gun 8 can pass through.
[0056] See also Figure 1 and Figure 4 , Figure 5As shown, the locking member 73 may be a bolt or the like, and the welding gun 8 can pass through the bayonet 71 and the through hole 12 and extend into the wind shield body 1. By turning the locking member 73 (bolt), the size of the adjustment opening 72 can be changed, thereby changing the size of the bayonet 71, so that the connecting plate 7 tightly wraps the welding gun 8, thereby fixing the welding gun 8 to the wind shield body 1. When the wind shield is not needed, the welding gun 8 can be removed from the wind shield body 1 by loosening the locking member 73.
[0057] The above structure can adapt to welding guns 8 with different outer diameters within a certain range, thereby improving the application range of the wind shield.
[0058] The wind shield of this embodiment can better fit the surface of the pipeline, thereby protecting the welding gun 8 in a relatively closed space, eliminating wind interference, effectively isolating the air from the molten pool, making the arc start stable, and ensuring the quality of the weld. Compared with the wind shield in the prior art, the wind shield is directly covered outside the welding gun 8, with a simple and compact structure, small size, and light weight, eliminating the time required for disassembly and assembly of the previous wind shield, and achieving the technical effect of reducing the preparation time before pipeline welding.
[0059] Embodiment 2:
[0060] See also Figure 1 As shown, this embodiment provides a welding gun 8 assembly for outdoor pipeline welding, including a welding gun 8 and the above-mentioned wind shield.
[0061] The welding gun 8 assembly used for outdoor pipeline welding has a small spacing between the wind shield and the outer wall of the pipeline, which eliminates wind interference, effectively isolates the air from the molten pool, stabilizes the arc, ensures the quality of the weld, and has the characteristics of small size and light weight.
