At the same time, it has high strength, low resistance, good sealing performance, beautiful appearance, simple installation and long service life, which can meet the needs of long-term use of galvanized air ducts in the region. During the production process of galvanized air ducts, various accessories need to be assembled on the galvanized air ducts. The accessories and galvanized air ducts are generally connected by welding to ensure that the connection between the two is strong and not easy to fall off.

[0003] The utility model discloses a metal air duct welding device (CN218253737U), comprising a workbench, a welding adjustment structure installed on the top of the workbench, the welding adjustment structure comprising a sliding mounting frame, a movable roller installed on the top of the sliding mounting frame, a fixing bolt installed on one end of the sliding mounting frame, a fixed roller installed on the top of the sliding mounting frame, a control box installed on one side of the workbench, a table body mounting frame installed on the top of the workbench, and a smoke purification structure installed on one end of the table body mounting frame. The utility model sets a welding adjustment structure, moves the movable roller on the sliding mounting frame according to the size of the air duct, and after moving to the corresponding position, the movable roller is fixed to the sliding mounting frame by passing through the interior of the sliding mounting frame and the movable roller through the fixing bolt, and the air duct is placed on the top of the movable roller and the fixed roller, thereby realizing the welding adjustment function. However, during use, there is a certain welding gap between the galvanized air ducts, so the welding masters need to work together in two people to reduce the gap between the galvanized air ducts as much as possible to meet the welding requirements. However, this operation still has a certain gap, and the welding masters need to seal the welds by feeding galvanized iron wire. This welding method is difficult to operate and takes a long time, which brings troubles to users.

[0004] To this end, we propose a galvanized sheet welding device for galvanized air duct production. Utility Model Content

[0005] The purpose of the utility model is to provide a galvanized sheet welding device for producing galvanized air ducts to solve the problems raised in the above background technology.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. 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. Example 1

[0020] See also Figure 1-4The utility model provides a technical solution: a galvanized sheet welding device for galvanized air duct production, comprising a base 1, a vertical baffle 2 and a sliding platform 4, a vertical baffle 2 is welded to the middle part of the upper end of the base 1, and a groove 21 is opened in the middle part of the inner side of the vertical baffle 2, slide rails 3 are welded on both sides of the upper end of the base 1, and the two ends of the outer wall of the slide rail 3 are slidably connected with the sliding platform 4, the middle part of the sliding platform 4 slides along the groove 21, a fixed platform 5 is fixed to the upper end of the middle of the slide rail 3, and the upper top surfaces of the sliding platform 4 and the fixed platform 5 are distributed in an arc surface, a fixing ring 41 is fixed to one side of the sliding platform 4, and a nut 42 is fixed to the inner wall of the fixing ring 41, a screw 6 is threadedly connected to the middle part of the inner wall of the nut 42, and the sliding platform 4 forms a threaded transmission structure with the screw 6 through the fixing ring 41 and the nut 42, and the outer thread of the screw 6 The threads are symmetrically distributed along the middle of the screw 6, and the sliding platform 4 adopts a threaded transmission structure design. When the user needs to assemble and weld two galvanized air ducts, the user can use this structure to lock the weld to be welded, thereby improving the welding success rate and reducing the difficulty of welding the two galvanized air ducts, bringing convenience to the user in welding galvanized air ducts and giving the user a better welding experience. At the same time, the sliding platform 4 adopts an "I"-shaped structure design, which can well contact and fix the first clamp 7 and the second clamp 71 to meet the needs of stable placement of the galvanized air duct. When the user needs to adjust the distance between the sliding platforms 4 at both ends, the user only needs to rotate the screw 6. Since the external threads of the screw 6 are symmetrically distributed along the middle of the screw 6, the sliding platforms 4 on both sides move toward or away from each other to meet the needs of butt welding the two galvanized air ducts. Example 2

[0021] See also Figure 1-4The second clamp 73 of the second clamp 71 is fixed to the upper end of the sliding base 4 at one end, and the second clamp 71 of the second clamp 7 is fixed to the upper end of the sliding base 4 at the other end. When the sliding platform 4 adjusts the weld seam of the galvanized air duct, the friction pad 74 can increase the friction coefficient between the first clamp 7 and the galvanized air duct, ensuring that the weld distance between the galvanized air duct can be effectively adjusted. In addition, the ends of the first clamp 7 and the second clamp 71 are fixed by bolts. When the galvanized air duct is connected, the two are pre-hardened to weld multiple fixed points between the galvanized air duct, and then the first clamp 7 and the galvanized air duct are loosened. Then, when the galvanized air duct is rotated, the galvanized air duct rolls along the ball 73 on the inner wall of the second clamp 71 to meet the requirements of the galvanized air duct welding process and ensure the rationality and feasibility of the entire structure.

[0022] Working principle: For this type of galvanized air duct production, the galvanized sheet welding device is first installed by respectively placing a pair of galvanized air ducts into the first clamp 7 and the second clamp 71. At this time, the first clamp 7 and the second clamp 71 are fastened to the pair of galvanized air ducts by bolts, and the friction pad 74 is interference-connected with one of the galvanized air ducts. Then the user rotates the screw 6. Since the external thread of the screw 6 is symmetrically distributed along the middle of the screw 6, the sliding platforms 4 on both sides move toward each other, reducing the gap between the two galvanized air ducts. At the same time, the user pre-welds the galvanized air duct around, and multiple welding points are welded on the surface of the galvanized air duct. At the same time, the first clamp 7 is loosened from the galvanized air duct. Finally, when rotating the galvanized air duct, the galvanized air duct rolls along the ball 73 on the inner wall of the second clamp 71 to meet the requirements of the galvanized air duct welding process.

[0023] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
