[0044] Such as Figure 1-5As shown in the figure, the present invention provides a welding system for the long-edge butt welding of short barrel sheet materials of stainless steel rocket storage tanks, comprising: a welding frame 2 and a loading and guiding component 6. The welding frame 2 includes an upper guide rail 2-4, a frame base 2-1 and a support base 2-2. The upper guide rail 2-4 and the frame base 2-1 are arranged at intervals and fixedly connected through the support base 2-2. The welding frame 2 is provided with a lower support surface 2-5 for supporting the steel plate. At least one of the opposite end faces of the upper guide rail 2-4 and the frame base 2-1 is provided with a welding head 9-1 movable along its length direction for welding the butt joint of the steel plate to be welded. The support base 2-2 is a C-shaped frame. The loading and guiding component 6 includes at least one loading and guiding bracket 6-1 for supporting the steel plate. At least one loading and guiding universal ball 6-2 is arranged on the upper end face of the loading and guiding bracket 6-1. The loading and guiding bracket 6-1 is docked with the lower support surface 2-5 to load the steel plate onto the lower support surface 2-5 for welding the steel plate.

[0045] The welding system provided in this embodiment changes the welding position of the three-dimensional welding equipment into the simplest flat welding position, and can realize the butt welding of the long edges of the short barrel longitudinal seam welding sheet materials (for example, laser butt welding), reducing the complexity of the equipment and the difficulty of equipment manufacturing, reducing the requirements for the equipment and the process difficulty, improving the stability of the weld formation, and enhancing the mechanical properties of the weld. The welding system has high welding stability, can realize the butt welding of the long edges of large-format steel plates, and is more likely to realize back gas protection. For example, the welding system can weld cold-rolled hardened 301 stainless steel plates with a length of 1000-7000 mm, a width of 300-1500 mm, and a thickness of 0.4-3.0 mm into large-format steel plates with a maximum specification of 7000 mm in length and 6000 mm in width.

[0046] For example, at least one loading guiding universal ball 6-2 is provided on the upper end surface of the loading guiding bracket 6-1, which can reduce the friction between the steel plate and the loading guiding component 6 during the advancement of the steel plate, and minimize the scratching of the steel plate during the transportation process. The welding frame 2 is the structural main body of the welding station of the welding system. For example, the frame base 2-1 can be a cast steel plate structure or a cast cement structure with a steel frame. For example, the bracket base 2-2 is a C-shaped frame. A plurality of (for example, 5) C-shaped frames can be arranged at intervals along the length direction of the upper guide rail 2-4. The opening of the C-shaped frame faces the upper guide rail 2-4, and the upper guide rail 2-4 is arranged on the upper end surfaces of the opposite end faces at the opening of the C-shaped frame. The bracket base 2-2 can be arranged on the frame base 2-1. The distance between the opposite end faces at the opening of the C-shaped frame can be 500-1500 mm. The bracket base 2-2 can be the main load-bearing body of the welding station and can be made of cast steel. For example, the loading guiding bracket 6-1 is an L-shaped bracket. The L-shaped bracket is inverted on the frame base 2-1 and can be connected to the frame base 2-1 by welding or screws. For example, a plurality of (for example, 13) loading guiding brackets 6-1 can be arranged at intervals along the length direction of the upper guide rail 2-4. For example, at least 4 sets of loading guiding universal balls 6-2 are arranged along the length direction of the loading guiding bracket 6-1. For example, the welding head 9-1 can be a laser welding head to perform laser welding on the steel plate. For example, the welding head 9-1 can perform laser welding on the long side butt joint of the long plate of the steel plate.

[0047] As Figure 2 and 6 As shown, according to an embodiment of the present invention, two lower support surfaces 2-5 are arranged side by side in the horizontal direction on the welding frame 2. The two lower support surfaces 2-5 are arranged at intervals. A lower guide rail 2-3 is arranged on the end face of the frame base 2-1 opposite to the upper guide rail 2-4. The upper guide rail 2-4 and the lower guide rail 2-3 are respectively provided with a welding head 9-1 to weld the butt joint from the front and back sides of the steel plate respectively.

[0048] In this embodiment, the upper guide rail 2-4 and the lower guide rail 2-3 are respectively provided with a welding head 9-1, which can perform double-sided welding (for example, laser welding) on the butt joint of the steel plate (for example, the long side straight seam). For example, the welding frame 2 can further include a column, and the upper guide rail 2-4 and the lower guide rail 2-3 can be fixedly connected to the column to enhance the structural stability. For example, the lower support surface 2-5 can be a triangular steel body, that is, a cast steel part with a triangular cross-section. The edge of the lower support surface 2-5 for contacting the steel plate can be provided with a chamfer. The distance between the two parallel lower support surfaces 2-5 can be 20-60 mm.

[0049] As Figure 6As shown, according to an embodiment of the present invention, at least one frame pressing mechanism 2-6 is provided on each side of the welding frame 2 along its length direction to press the steel plate on both sides of the butt joint. The frame pressing mechanism 2-6 includes a frame pressing driving cylinder and a pressing block. The pressing block is fixedly connected to the telescopic rod of the frame pressing driving cylinder. By the telescopic movement of the telescopic rod of the frame pressing driving cylinder, the pressing block is driven to approach or move away from the steel plate.

[0050] In this embodiment, for example, the frame pressing driving cylinder can be a cylinder. The frame pressing mechanism 2-6 can also adopt an airbag pressing mechanism. For example, the distance between the frame pressing mechanisms 2-6 on both sides of the welding frame 2 can be 20-60 mm. The opposite end faces of the frame pressing mechanisms 2-6 on both sides of the welding frame 2 are aligned with the opposite end faces of the corresponding lower support surfaces 2-5.

[0051] As Figure 1 and 7 As shown, according to an embodiment of the present invention, the loading guiding bracket 6-1 is used to be placed on one side of the welding frame 2. At least one of the opposite end faces of the upper guide rail 2-4 and the frame base 2-1 is provided with a rolling-positioning component 8 that is movable along its length direction. The rolling-positioning component 8 includes a rolling driving cylinder 8-1, a rolling wheel 8-2, a rolling-positioning driving cylinder 8-3, and a rolling-positioning baffle 8-4. The rolling wheel 8-2 is rotatably connected to the telescopic rod of the rolling driving cylinder 8-1. By the telescopic movement of the telescopic rod of the rolling driving cylinder 8-1, the rolling wheel 8-2 is driven to approach or move away from the steel plate to roll the butt joint of the steel plate. The rolling-positioning baffle 8-4 is fixedly connected to the telescopic rod of the rolling-positioning driving cylinder 8-3. By the telescopic movement of the telescopic rod of the rolling-positioning driving cylinder 8-3, the height of the rolling-positioning baffle 8-4 is adjusted. The rolling-positioning baffle 8-4 is used to control the loading position of the steel plate at the lower support surface 2-5.

[0052] In this embodiment, the center line of the rolling wheel 8-2 along the length direction of the lower guide rail 2-3 is horizontally offset from the center line of the baffle 8-4 along the length direction of the lower guide rail 2-3. For example, the center line of the rolling wheel 8-2 along the length direction of the lower guide rail 2-3 and the center line of the gap between the two lower support surfaces 2-5 along the length direction of the lower guide rail 2-3 are in the same vertical plane, and the center line of the baffle 8-4 along the length direction of the lower guide rail 2-3 and the center line of the gap between the two lower support surfaces 2-5 along the length direction of the lower guide rail 2-3 are not in the same vertical plane.

[0053] This welding system controls the feeding position of the steel plate at the lower support surface 2-5 in the direction of transporting the steel plate from the feeding guide bracket 6-1 to the welding frame 2 through the rolling-positioning baffle 8-4, and the rolling-positioning component 8 can flatten and shape the weld seam, eliminate the excess height of the weld seam, prevent welding deformation, and improve the weld strength. For example, the opposite end faces of the upper guide rail 2-4 and the frame base 2-1 (e.g., the lower guide rail 2-3) are respectively provided with rolling-positioning components 8 that are movable along their lengths to jointly position the lateral position of the steel plate. For example, the rolling drive cylinder 8-1 can be an electric cylinder. The rolling-positioning drive cylinder 8-3 can be a pneumatic cylinder. The rolling drive cylinder 8-1 can be locked to the lower guide rail 2-3 by screws. The thickness of the rolling wheel 8-2 can be 10-50 mm. The rolling-positioning drive cylinder 8-3 and the rolling drive cylinder 8-1 can be distributed along the length direction of the upper guide rail 2-4 or the lower guide rail 2-3. The rolling-positioning drive cylinder 8-3 can be arranged beside the rolling drive cylinder 8-1. The rolling-positioning component 8 can be used to perform lateral ( Figure 6 in the S1 direction in

[0054] For example, when butt-welding the first steel plate to be welded and the second welded steel plate, the steps can be as follows:

[0055] S01: Along the length directions of the lower guide rail 2-3 and the upper guide rail 2-4, respectively adjust the positions of the corresponding rolling-positioning components 8 provided thereon until the two rolling-positioning components 8 are close to both ends of the lower guide rail 2-3;

[0056] S02: The telescopic rod of the rolling drive cylinder 8-1 retracts to move the rolling wheel 8-2 away from the lower support surface 2-5; the telescopic rod of the rolling-positioning drive cylinder 8-3 retracts to move the rolling-positioning baffle 8-4 away from the lower support surface 2-5;

[0057] S03: The feeding guide bracket 6-1 transports the first steel plate to be welded to the welding frame 2 until the welding edge of the first steel plate to be welded reaches the lower support surface 2-5 away from the feeding guide component 6;

[0058] S04: The telescopic rods of the rolling-positioning drive cylinders 8-3 provided on the lower guide rail 2-3 and the upper guide rail 2-4 extend to make the rolling-positioning baffle 8-4 located between the two lower support surfaces 2-5 on the side in the width direction of the lower guide rail 2-3;

[0059] S05: Push back the first steel plate to be welded (i.e., push the first steel plate to be welded in the direction of the feeding guide component 6, which can be manually pushed) so that the welding edge of the first steel plate to be welded abuts against the side of the rolling-positioning baffle 8-4 in the width direction of the lower guide rail 2-3;

[0060] S06: The telescopic rod of the rolling-positioning driving cylinder 8-3 retracts, moving the rolling-positioning baffle 8-4 away from the lower support surface 2-5. The feeding guiding bracket 6-1 transports the second steel plate to be welded to the welding frame 2, causing the welding edges of the second steel plate to be welded to be spliced with those of the first steel plate to be welded, and then welding is performed.

[0061] S07: The telescopic rod of the rolling driving cylinder 8-1 extends, bringing the rolling wheel 8-2 close to the weld seam and rolling the weld seam.

[0062] As Figure 1 and 8 As shown in [figures not specified], according to an embodiment of the present invention, in addition to the welding frame 2 and the feeding guiding component 6, the welding system further includes a feeding lateral positioning component 3. The feeding lateral positioning component 3 includes a feeding lateral positioning guide rail 3-1, a feeding lateral positioning column base 3-2, and a feeding lateral positioning column 3-3. The feeding lateral positioning column 3-3 is disposed on the feeding lateral positioning column base 3-2. The feeding lateral positioning column base 3-2 is disposed on the feeding lateral positioning guide rail 3-1. The feeding lateral positioning component 3 is placed beside the feeding guiding bracket 6-1, and the feeding lateral positioning guide rail 3-1 is arranged along the feeding direction from the feeding guiding component 6 to the welding frame 2. The feeding lateral positioning column base 3-2 is movable relative to the feeding lateral positioning guide rail 3-1, enabling the feeding lateral positioning column 3-3 to push the steel plate from the feeding guiding bracket 6-1 to the lower support surface 2-5.

[0063] In the welding system provided in this embodiment, the feeding lateral positioning component 3 guides, advances, and positions the feeding of the steel plate. For example, the welding system can be provided with multiple (e.g., four sets) of feeding lateral positioning components 3. The feeding lateral positioning components 3 and the feeding guiding brackets 6-1 can be alternately arranged. For example, the feeding lateral positioning guide rail 3-1 can be a linear guide rail for controlling the linear movement of the feeding lateral positioning column base 3-2 and the feeding lateral positioning column 3-3. For example, the feeding lateral positioning column 3-3 can be a cylindrical steel bar, and the side of the steel bar is used to contact the steel plate. By moving the feeding lateral positioning column base 3-2 along the feeding lateral positioning guide rail 3-1, the feeding lateral positioning column 3-3 advances the steel plate in the feeding direction at the side of the steel plate.

[0064] As Figure 1 and 9As shown, according to an embodiment of the present invention, in addition to the welding frame 2 and the feeding guiding member 6, the welding system further includes a feeding positioning member 5. The feeding positioning member 5 includes a feeding positioning column 5-1, a feeding positioning driving cylinder 5-2, and a feeding positioning baffle 5-3. The feeding positioning driving cylinder 5-2 is disposed on the feeding positioning column 5-1, and the feeding positioning baffle 5-3 is fixedly connected to the telescopic rod of the feeding positioning driving cylinder 5-2. For example, when feeding a steel plate onto the feeding guiding member 6 along the length direction of the upper guide rail 2-4, the feeding positioning member 5 is placed at the end of the feeding guiding member 6 along the feeding direction. By the telescopic movement of the telescopic rod of the feeding positioning driving cylinder 5-2, the feeding positioning baffle 5-3 is driven to lean against or away from the steel plate, so as to limit the feeding of the steel plate onto the feeding guiding member 6.

[0065] In this embodiment, the feeding positioning member 5 can longitudinally position the steel plate. For example, on both sides in the width direction of the welding frame 2, at least one (for example, 6 sets can also be used) feeding positioning member 5 can be respectively provided. For example, the feeding positioning driving cylinder 5-2 can be an electric cylinder. For example, the feeding positioning baffle 5-3 can be a steel plate of 50*50mm. The thickness of the feeding positioning baffle 5-3 in the vertical direction can be equal to or greater than the thickness of the steel plate to be welded.

[0066] As Figure 1 , 3 As shown in FIGS. 10-12, according to an embodiment of the present invention, in addition to the welding frame 2 and the feeding guiding member 6, the welding system further includes a discharging guiding member 7. The discharging guiding member 7 includes at least one discharging guiding bracket 7-1, and the discharging guiding bracket 7-1 is used to support the steel plate. At least one discharging guiding universal ball 7-2 is provided on the upper end surface (i.e., the end surface for supporting the steel plate) of the discharging guiding bracket 7-1. The discharging guiding member 7 is docked with the lower supporting surface 2-5, so as to discharge the steel plate from the lower supporting surface 2-5 through the discharging guiding bracket 7-1 and the discharging guiding universal ball 7-2.

[0067] In this embodiment, for example, along the length direction of the lower supporting surface 2-5, a plurality of (for example, 7 sets or 9 sets) discharging guiding brackets 7-1 can be provided. For example, at least one discharging guiding universal ball 7-2 (for example, 13 sets can also be provided) is provided on the upper end surface of the discharging guiding bracket 7-1, which can reduce the friction between the steel plate during travel and the discharging guiding member 7, and maximize the elimination of scratches on the steel plate during the transportation of the steel plate.

[0068] As Figure 3 , 10, as shown in 11, 13, and 14, according to an embodiment of the present invention, in addition to the welding frame 2, the loading guiding member 6, and the unloading guiding member 7, the welding system further includes an unloading side positioning member 4. The unloading side positioning member 4 includes an unloading side positioning guide rail 4-1, an unloading side positioning column base 4-2, an unloading side positioning column 4-3, and an unloading side positioning pressing mechanism 4-4. The unloading side positioning pressing mechanism 4-4 is disposed on the unloading side positioning column 4-3. The unloading side positioning column 4-3 is disposed on the unloading side positioning column base 4-2. The unloading side positioning column base 4-2 is disposed on the unloading side positioning guide rail 4-1.

[0069] As Figure 13 , 14 shown, the unloading side positioning pressing mechanism 4-4 includes an unloading side positioning pressing base 4-4-1, an unloading side positioning pressing column 4-4-2, an unloading side positioning pressing drive cylinder 4-4-3, and an unloading side positioning pressing pad 4-4-4. The unloading side positioning pressing base 4-4-1 is disposed on the unloading side positioning column 4-3. The unloading side positioning pressing column 4-4-2 is disposed on the unloading side positioning pressing base 4-4-1. The unloading side positioning pressing drive cylinder 4-4-3 is disposed on the unloading side positioning pressing column 4-4-2. The unloading side positioning pressing pad 4-4-4 is fixedly connected to the telescopic rod of the unloading side positioning pressing drive cylinder 4-4-3.

[0070] The unloading side positioning member 4 is placed beside the unloading guiding bracket 7-1, and the unloading side positioning guide rail 4-1 is arranged along the unloading direction from the welding frame 2 to the unloading guiding bracket 7-1. By extending the telescopic rod of the unloading side positioning pressing drive cylinder 4-4-3, the unloading side positioning pressing pad 4-4-4 is driven to press the steel plate against the unloading side positioning pressing base 4-4-1. The unloading side positioning column base 4-2 is movable relative to the unloading side positioning guide rail 4-1, so that the unloading side positioning pressing mechanism 4-4 transports the steel plate from the welding frame 2 to the unloading guiding bracket 7-1 to complete the unloading of the steel plate (i.e., pulling the steel plate to unload from the welding frame 2).

[0071] In this embodiment, the blanking side positioning and pressing mechanism 4-4 makes the blanking side positioning and pressing pad 4-4-4 press or release the steel plate by the telescopic movement of the telescopic rod of the blanking side positioning and pressing drive cylinder 4-4-3. The blanking side positioning guide rail 4-1 controls the linear movement of the blanking side positioning column base 4-2 and the blanking side positioning column 4-3, so that the blanking side positioning and pressing mechanism 4-4 drives the steel plate to move and position along the length direction of the blanking side positioning guide rail 4-1. For example, the welding system can be provided with multiple (for example, 5 sets) blanking side positioning components 4. The blanking side positioning components 4 can be arranged alternately with the blanking guiding components 7. For example, the blanking side positioning guide rail 4-1 can be a linear guide rail. For example, the blanking side positioning and pressing base 4-4-1 can be a steel plate, and chamfers of 10-30° are provided at the steel plate loading and unloading positions. For example, the blanking side positioning and pressing drive cylinder 4-4-3 can be a pneumatic cylinder. The blanking side positioning and pressing drive cylinder 4-4-3 can be arranged on the side of the blanking side positioning and pressing column 4-4-2, and the telescopic rod of the blanking side positioning and pressing drive cylinder 4-4-3 is arranged towards the blanking side positioning and pressing base 4-4-1. For example, the blanking side positioning and pressing pad 4-4-4 can be a rubber pad.

[0072] As Figure 2 and 6 shown, according to an embodiment of the present invention, the welding system further includes a rectangular grid frame 2-7. The blanking guiding components 7 and the blanking side positioning components 4 are installed on the rectangular grid frame 2-7.

[0073] In this embodiment, for example, the rectangular grid frame 2-7 can be welded by square steel. The rectangular grid frame 2-7 can be installed on the frame base 2-1.

[0074] As Figure 1 、 3 、11 and 15 shown, according to an embodiment of the present invention, in addition to the welding frame 2 and the loading guiding components 6, the welding system further includes a loading component 1. The loading component 1 is placed beside the loading guiding components 6. The loading component 1 includes a loading frame 1-1, a driving roller 1-2 and a loading rotating motor. The driving roller 1-2 is rotatably arranged relative to the loading frame 1-1, and the driving roller 1-2 is used to support the steel plate. The driving roller 1-2 is fixedly connected to the rotating shaft of the loading rotating motor. Starting the loading rotating motor drives the driving roller 1-2 to rotate to transport the steel plate to the loading guiding components 6.

[0075] In this embodiment, the feeding component 1 can provide feeding driving force for the steel plate. Start the feeding rotating motor, and the feeding component 1 pushes the steel plate towards the feeding guiding component 6, and pushes it (it can be manually pushed) to the feeding positioning component 5 to complete the previous process of feeding. For example, the feeding guiding component 1 can be placed on the side of the feeding guiding component 6 away from the feeding positioning component 5. For example, multiple sets (for example, 5 sets) of driving rollers 1-2 and feeding rotating motors can be arranged on the feeding component 1, and the driving rollers 1-2 and the feeding rotating motors are arranged in one-to-one correspondence. For example, the advancing direction of the feeding component 1 for the steel plate can form a certain angle (for example, 2-10°) with the length direction of the steel plate weld (i.e., the long side of the steel plate), which is convenient for adjusting the feeding position in the subsequent process.

[0076] As Figure 3 , 4 , 16 and 17 show, according to an embodiment of the present invention, at least one of the opposite end faces of the upper guide rail 2-4 and the frame base 2-1 is provided with a welding component 9. The welding component 9 includes a welding head 9-1, a front anti-edge-mismatch roller mechanism 9-2, a rear anti-edge-mismatch roller mechanism 9-4 and a side-axis protection gas mechanism 9-3. The front anti-edge-mismatch roller mechanism 9-2 includes a front anti-edge-mismatch driving cylinder and a front anti-edge-mismatch roller. The front anti-edge-mismatch roller is rotatably connected to the telescopic rod of the front anti-edge-mismatch driving cylinder. Along the welding direction, the front anti-edge-mismatch roller mechanism 9-2 is arranged on the front side of the welding head 9-1. By the telescopic movement of the telescopic rod of the front anti-edge-mismatch driving cylinder, the front anti-edge-mismatch roller is driven to press or release the weld on the front side of the welding head 9-1.

[0077] Refer to Figure 17 , the rear anti-edge-mismatch roller mechanism 9-4 includes a rear anti-edge-mismatch rotating motor 9-4-1, a rear anti-edge-mismatch driving cylinder 9-4-2 and a rear anti-edge-mismatch roller 9-4-3. The rear anti-edge-mismatch driving cylinder 9-4-2 is fixedly connected to the rotating shaft of the rear anti-edge-mismatch rotating motor 9-4-1. Start the rear anti-edge-mismatch rotating motor 9-4-1, and drive the rear anti-edge-mismatch driving cylinder 9-4-2 to rotate in the vertical plane. The rear anti-edge-mismatch roller 9-4-3 is rotatably connected to the telescopic rod of the rear anti-edge-mismatch driving cylinder 9-4-2. Along the welding direction, the rear anti-edge-mismatch roller 9-4-3 is arranged on the rear side of the welding head 9-1. By the telescopic movement of the telescopic rod of the rear anti-edge-mismatch driving cylinder 9-4-2, the rear anti-edge-mismatch roller 9-4-3 is driven to press or release the weld on the rear side of the welding head 9-1.

[0078] As Figure 4 shows, the side-axis protection gas mechanism 9-3 is arranged beside the welding head 9-1. The side-axis protection gas mechanism 9-3 includes a protection gas inlet and a protection gas outlet. The protection gas inlet is used to guide the protection gas to the protection gas outlet to provide gas protection for the weld.

[0079] The welding system provided in this embodiment can eliminate the edge misalignment of the steel plate before welding and during spot welding through the front anti-edge-misalignment roller mechanism 9-2 and the rear anti-edge-misalignment roller mechanism 9-4. For example, welding components 9 are respectively arranged on the opposite end faces of the upper guide rail 2-4 and the frame base 2-1 (for example, the lower guide rail 2-3) to perform double-sided welding on the butt straight seam of the steel plate on the front and back sides of the steel plate. For example, both the upper guide rail 2-4 and the lower guide rail 2-3 can be common-rail linear tracks. The rolling-positioning component 8 and the welding component 9 can adopt a common sliding track and different linear gear tracks, so that the upper guide rail 2-4 and the lower guide rail 2-3 control the rolling-positioning component 8 and the welding component 9 to perform linear motion.

[0080] For example, the welding component 9 can be provided with an X-axis slider, a Y-axis slider, and a Z-axis slider to form a three-axis linkage system of the welding head 9-1. For example, the X-axis slider can be installed on the upper guide rail 2-4 or the lower guide rail 2-3. For example, the front anti-edge-misalignment roller mechanism 9-2 can be locked on the front side of the welding head 9-1 by screws, and the rear anti-edge-misalignment roller mechanism 9-4 can be locked on the rear side of the welding head 9-1 (for example, the Z-axis slider) by screws. For example, the front anti-edge-misalignment driving cylinder can be an electric cylinder. For example, the widths of the front anti-edge-misalignment roller and the rear anti-edge-misalignment roller 9-4-3 can be 10 to 40 mm. For example, the rear anti-edge-misalignment roller 9-4-3 can be a double-roller structure. For example, the rear anti-edge-misalignment rotating motor 9-4-1 can be locked on the Z-axis slider by screws.

[0081] As Figure 16 shown, according to an embodiment of the present invention, the side-axis protective gas mechanism 9-3 includes a light-shielding plate 9-3-1, a front protective gas outlet 9-3-2, a front protective gas inlet 9-3-3, a rear protective gas inlet 9-3-4, a gas knife 9-3-5, a locking flange plate 9-3-6, and a protective gas column 9-3-7. The protective gas column 9-3-7 is locked on the welding head 9-1 through the locking flange plate 9-3-6. The front protective gas inlet 9-3-3 and the rear protective gas inlet 9-3-4 are arranged on the side surface of the protective gas column 9-3-7. The lower end surface of the protective gas column 9-3-7 is provided with a rear protective gas outlet (not shown in the figure). At the front end in the welding direction, an inclined surface is provided at the lower end of the protective gas column 9-3-7, and the front protective gas outlet 9-3-2 is provided at the inclined surface. The front protective gas inlet 9-3-3 and the rear protective gas inlet 9-3-4 are used to communicate with the protective gas pipeline. The front protective gas inlet 9-3-3 is communicated with the front protective gas outlet 9-3-2, and the rear protective gas inlet 9-3-4 is communicated with the rear protective gas outlet to guide the protective gas to the weld. A light-shielding plate 9-3-1 is provided at the lower end of the protective gas column 9-3-7, and the light-shielding plate 9-3-1 is used to block light to prevent the welding components 9 from burning the welding elements on this side during welding. A gas knife 9-3-5 is provided in the middle of the protective gas column 9-3-7, and gas is introduced into the gas knife 9-3-5 to protect the lens of the welding head 9-1.

[0082] In this embodiment, the off-axis shielding gas mechanism 9-3, as the gas shielding mechanism for the front and back of the welding component 9, can provide gas shielding for the weld seam. For example, the locking flange plate 9-3-6 can be arranged at the top of the shielding gas column 9-3-7. For example, at least one front shielding gas inlet 9-3-3 and one rear shielding gas inlet 9-3-4 can be arranged on the side of the shielding gas column 9-3-7. For example, one front shielding gas inlet 9-3-3 and three rear shielding gas inlets 9-3-4 can be arranged on the side of the shielding gas column 9-3-7. For example, the front shielding gas inlet 9-3-3 and the rear shielding gas inlet 9-3-4 can be standard tracheal adapters. For example, the front shielding gas outlet 9-3-2 can be a round hole with an inner diameter of 5-10 mm. For example, the rear shielding gas outlet can be a rectangular slot hole with a width of 4-10 mm, a length of 50-70 mm, and a depth of 100-200 mm. For example, the light shielding plate 9-3-1 can be 40-50 mm wide, 60-80 mm long, and 5-30 mm thick.

[0083] In the present invention, the above-mentioned components, assemblies or parts can be connected and fixed by means of screws, riveting, welding, etc., and the present invention does not make specific limitations in this regard. For example, the rolling-positioning baffle 8-4 is fixed at the end of the telescopic rod of the rolling-positioning driving cylinder 8-3 by welding; the feeding guiding universal ball 6-2 is locked to the feeding guiding bracket 6-1 by screws; the feeding guiding bracket 6-1 can be fixed to the lower support surface 2-5 by welding or screws; the feeding side positioning column base 3-2 is locked to the feeding side positioning guide rail 3-1 by screws; the feeding positioning column 5-1 is fixed to the frame base 2-1 by welding or screws; the feeding positioning driving cylinder 5-2 is installed at the top of the feeding positioning column 5-1 by screws; the feeding positioning baffle 5-3 is connected to the end of the telescopic rod of the feeding positioning driving cylinder 5-2 by welding; the discharging guiding bracket 7-1 is connected to the frame base 2-1 and the lower support surface 2-5 by welding or screws; the discharging guiding universal ball 7-2 is locked to the discharging guiding bracket 7-1 by screws.
