Description

Technical Field

[0001] This invention relates to the field of argon arc welding machine technology, specifically to an argon arc welding machine for transformers. Background Technology

[0002] Argon arc welding, as a high-quality welding method, relies on the effective protection of the weld pool by an inert gas (such as argon) to prevent air intrusion that could lead to weld oxidation and porosity. Traditional argon arc welding operations, especially in outdoor environments, face two long-standing and interconnected technical bottlenecks.

[0003] First, there is a disconnect between pre-weld cleaning and the welding process. The oxide layer, oil, and moisture on the bevel and both sides of the workpiece are key factors affecting the welding quality. In the existing technology, pre-weld cleaning usually relies on independent hand tools such as angle grinders and wire brushes to complete the pre-cleaning in advance. This method is inefficient and the cleanliness is difficult to guarantee. After pre-cleaning, the bevel may be contaminated again before welding, especially in dusty and windy outdoor environments.

[0004] Secondly, there are limitations to outdoor windproof protection. The protective gas is easily dispersed by lateral airflow, leading to protection failure. Existing solutions mainly fall into two categories: one is a large, independent windproof canopy, which is time-consuming and labor-intensive to build, difficult to move, and cannot meet the needs of mobile and rapid welding operations. Summary of the Invention

[0011] Preferably, the air blowing mechanism includes two L-shaped connecting plates, both of which are bolted to adjacent connecting plates. A windshield is fixedly connected to one side of each of the two L-shaped connecting plates. The windshield has a funnel-shaped cross-section and a cavity inside.

[0012] Preferably, the wind shield is placed on the outside of the welding torch near the front side, the wind shield has a round hole on the outside, a transmission tube is inserted into the right side of the wind shield, the other end of the transmission tube passes through the adjacent L-shaped connecting plate and extends to the top of the reciprocating wheel, and an annular soft pad is fixedly connected to the front side of the wind shield.

[0014] Compared with the prior art, the beneficial effects of the present invention are: The present invention enables the cleaning action to be dynamic and synchronous with the welding process through the cleaning mechanism. The contact wheel rolls along the surface of the workpiece, and its rotation is converted into the reciprocating motion of the scraper through the linkage mechanism. Thus, while the welding torch moves, it continuously scrapes away the contaminants at the front bevel. After the windproof mechanism is deployed, it forms a local flexible sealing area around the electric arc. The two work together to form a clean area in front of the welding torch, which constitutes a mobile and clean welding microenvironment. This invention's windbreak mechanism enables the rotating wheel to turn when there is strong outdoor wind. This, in turn, drives a scraper to reciprocate and clean the slope via a linkage mechanism. The stronger the wind, the more frequent the cleaning action, and the stronger the effect. This transforms environmental disadvantages into functional advantages, achieving adaptive enhanced cleaning without additional energy consumption, making it highly economical and environmentally friendly.

[0020] Working principle: First, the user attaches two sleeves 10 to the outside of the welding torch 3 and moves the two sleeves 10 in opposite directions. When the sleeves 10 move in opposite directions, they can drive the adjacent moving plates 29 to move in opposite directions. When the moving plates 29 move, the movement trajectory can be limited by the magnetic locking block 30 engaging with the slide groove. When the moving plates 29 are together, they can be fixed by the magnetic locking block 30. The magnetic locking block 30 limits and fixes the placement plate 31 by engaging with the magnetic strip. When the user pushes the welding torch 3 along the slope of the workpiece... When welding at the joint, the rubber block on the outer side of the contact wheel 5 can contact the outer side of the workpiece, thus rotating. When the contact wheel 5 rotates, it can drive the driving grooved wheel 15 to rotate via the transmission rod 21. When the driving grooved wheel 15 rotates, it can drive the driven grooved wheel 19 to rotate via the belt 14. When the driven grooved wheel 19 rotates, it can drive the driving bevel gear 16 to rotate via the rotating shaft. When the driving bevel gear 16 rotates, it can drive the driven bevel gear 17 to rotate. When the driven bevel gear 17 rotates, it can drive the rotating rod 27 to rotate. When the rotating rod 27 rotates, it can... The reciprocating wheel 22 rotates, and when it rotates, it engages with the meshing block 26, thereby driving the reciprocating plate 25 to move. The reciprocating plate 25, by engaging with the limiting plate 24, can convert the movement trajectory into linear movement, thereby driving the scraper 4 to reciprocate. The scraper 4 can clean the bevel of the workpiece. When it is necessary to drive the reciprocating wheel 22 to rotate by wind power, the bearing 20 can be moved downward by the pull rod 18. When the bearing 20 moves, it can also drive the driven bevel gear 17 to move downward, so that the driven bevel gear... 17 disengages from the active bevel gear 16 to prevent the active bevel gear 16 from rotating. Since the slider 28 is made of magnetic material, it can limit and fix the position of the driven bevel gear 17. The shielding gas of the welding torch 3 can be protected by the wind shield 12. When the wind enters the inner cavity of the wind shield 12 through the round hole, it can contact the blade 9 through the transmission pipe 8 and drive the blade 9 to rotate. When the blade 9 rotates, it drives the reciprocating wheel 22 to rotate through the central shaft 23, thereby driving the scraper 4 to move back and forth.
