Abstract
Description
Technical Field
[0001] This utility model relates to the field of laser welding air knife technology, specifically to an air blowing and wire feeding device for laser welding air knives. Background Technology
[0002] A laser welding air knife is an important auxiliary device used in laser welding processes. It protects and cleans the welding area by spraying high-speed gas, thereby improving the quality and effect of laser welding. During laser welding, an air blowing and wire feeding device is needed to assist the laser welding air knife. Air blowing and wire feeding are closely coordinated. When welding begins, gas is first ejected through the nozzle to form a protective atmosphere in the welding area. At the same time, the wire feeding mechanism starts working, delivering the welding wire to the weld pool at a set speed and direction. The speed and pressure of the air blowing must be matched with the wire feeding speed. The wire feeding speed also needs to be reasonably adjusted according to factors such as welding current, voltage, and weld shape to ensure that the welding wire can fully melt and fuse with the workpiece to form a high-quality weld.
[0003] The applicant believes that:
[0004] When using an air-blowing wire feeding device to assist in the operation of a laser welding air knife, it is often difficult to properly adjust the positions of the air blowing tube and the wire feeding tube. This can easily lead to the air blowing tube and the wire feeding tube not being on the same side, and the wire feeding direction not being consistent with the air blowing direction. During the wire feeding process, this may cause a certain impact and interference to the molten pool, resulting in large fluctuations in the molten pool. This, in turn, affects the formation and quality of the weld, leading to uneven weld width and inconsistent reinforcement height. Furthermore, it increases interference with the workpiece during welding and makes it difficult to weld corner positions, thus requiring improvement. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] To address the shortcomings of existing technologies, this utility model provides an air-blowing and wire-feeding device for laser welding air knives. This device features position adjustment for both the air-blowing and wire-feeding tubes, solving the problem of inadequate position adjustment in many existing systems. This often results in the air-blowing and wire-feeding tubes being misaligned, the wire-feeding direction being inconsistent with the air-blowing direction, and potential impact and interference on the molten pool during wire feeding. This leads to significant molten pool fluctuations, affecting weld formation and quality, resulting in uneven weld width and reinforcement height, increased interference with the workpiece during welding, and difficulty in welding corners and edges.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1 to 4 This utility model provides a technical solution: a blowing wire feeding device for laser welding air knife, including a laser welding gun 1, a connecting rod 2 and a position adjustment component 3. The connecting rod 2 is provided on one side of the laser welding gun 1, the position adjustment component 3 is provided on the lower outer wall of the connecting rod 2, the mounting and fixing component 4 is provided on the upper outer wall of the connecting rod 2, and the air knife body 5 is installed below the laser welding gun 1.
[0027] Specifically: When the air blowing and wire feeding device assists the laser welding air knife in operation, the connecting rod 2 is first installed on one side of the laser welding gun 1 by installing and fixing component 4. Then, according to the position of the air knife body 5 on the laser welding gun 1, the air blowing pipe 304 and the wire feeding pipe 310 are adjusted to a suitable position by the position adjustment component 3 to cooperate with the air knife body 5 in operation.
[0028] Please see Figure 1 , Figure 2 and Figure 3 A blowing wire feeding device based on a laser welding air knife includes a position adjustment component 3 comprising a main clamping block 301, a main adjusting clamp 302, a main mounting base 303, an air blowing pipe 304, an air pipe docking seat 305, a valve 306, a gas flow meter 307, a secondary adjusting clamp 308, a secondary mounting base 309, a wire feeding pipe 310, a main screw 311, and a main nut 312. The main clamping block 301 is movably connected to the lower outer wall of the connecting rod 2. The main adjusting clamp 302 is welded to one side of the outer wall of the main clamping block 301.

The upper part of the air tube docking seat 305 is fitted with a valve 306. The lower part of the air tube docking seat 305 is fitted with a gas flow meter 307.
[0029] Specifically: When the position adjustment component 3 adjusts the position of the air blowing pipe 304 and the wire feeding pipe 310, loosening the main screw 311 and the main nut 312 allows for adjustment of the rotation and height of the main clamp 301, as well as the angle adjustment of the main mounting base 303 inside the main adjusting clamp 302. This provides the air blowing pipe 304 with the function of adjusting its rotation angle and position.

Tightening the main screw 311 and the main nut 312 further adjusts the position of the air blowing pipe 304. The air pipe 304 and the wire feeding pipe 310 provide a fixed purpose, and through the adjustability of the air pipe 304 and the wire feeding pipe 310, they can be adjusted to the same side as needed to ensure that the wire feeding direction is consistent with the air blowing direction, so that the welding wire can enter the molten pool more smoothly, reducing the impact and interference on the molten pool, thereby making the molten pool more stable, which helps to form a uniform and continuous weld, improves the weld formation quality and appearance flatness, and reduces interference with the workpiece during welding, making it easier to weld corner positions. In addition, through the cooperation of the valve 306 and the gas flow 307, the gas flow can be controlled and monitored.
[0030] Please see Figure 1 , Figure 2 and Figure 4 A blowing wire feeding device based on a laser welding air knife is disclosed.

The secondary nut 407 is threaded to the outer wall of the other end of the secondary screw 406.
[0031] Specifically, during the installation and adjustment of the connecting rod 2 by installing the fixing component 4, the mounting plate 404 is first brought into contact with the laser welding gun 1, and then the fixing bolt is screwed into the mounting hole 405 to install the auxiliary clamp 403. Subsequently, the connecting rod 2 slides on the limiting slider 402 through the limiting groove 401, and then the auxiliary screw 406 is tightened in conjunction with the auxiliary nut 407, thereby enabling the height adjustment function of the connecting rod 2 and providing effective protection for the overall height adjustment of the air blowing pipe 304 and the wire feeding pipe 310 on the connecting rod 2.

Then, the auxiliary screw 406 is tightened with the auxiliary nut 407 to fix the connecting rod 2. After the connecting rod 2 is installed and fixed, the main screw 311 is loosened with the main nut 312. Then, the air-blowing pipe 304 and the wire feeding pipe 310 are adjusted to a suitable position according to the requirements. Then, the main screw 311 is tightened with the main nut 312 to fix the adjusted air-blowing pipe 304 and the wire feeding pipe 310.
