Description

Technical Field

[0001] The invention relates to the technical field of welding devices, in particular to an aluminum alloy door and window welding machine. Background Art

[0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy profiles as frames, stiles and fan materials. With continuous application, various types of aluminum alloy doors and windows have appeared in the market.

[0003] The existing circular aluminum alloy door and window brackets are welded after being spliced ​​in multiple sections due to their special shape. The welds are prone to deflection during welding, and the door and window brackets are provided with assembly grooves, which easily miss dead corners during welding. In addition, since aluminum alloys easily form a dense aluminum oxide film when in contact with air, and its melting point is much higher than that of aluminum, this oxide film will hinder the fusion of the weld. Continuing high-temperature welding at this time will cause the weld to re-oxidize, and will cause defects such as slag inclusions, unfusion, and insufficient penetration. Before the window frame is welded, the outside will be contaminated with oil or other impurities, which will remain on the metal surface and affect the welding quality. For this reason, we propose an aluminum alloy door and window welding machine. Summary of the invention

[0015] Compared with the prior art, the present invention provides an aluminum alloy door and window welding machine, which has the following beneficial effects: 1. Through the cooperation between the second electric telescopic rod and the first welding head, not only the welds between the arc window frames can be welded, but also the inner welds of the assembly grooves can be welded to avoid leaving dead angles, making the welding more comprehensive and the connection between the arc window frames more stable. Through the cooperation between the fourth gear and the third electric telescopic rod, the position around the arc window frame welding can be fully cleaned before the weld is welded to avoid the appearance of cracks and bubbles during welding, making the weld more firm and reliable. Through the cooperation between the feed pipe and the third electric telescopic rod, the cleaning agent can be output during cleaning to flush the impurities such as grease around the weld, so that the weld is cleaned, thereby improving the welding quality. The amount of metal surface oxides and rust can be removed, which can slow down the natural oxidation and corrosion rate of the weld, thereby extending the service life of the weld. Through the cooperation of the arc soft brush and the arc brush block, under the rotation of the C-shaped rotating plate, the oxide layer produced on the outside of the weld is fully polished, and the inner side of the fixed tooth can be rubbed, thereby improving the welding efficiency. The polished aluminum alloy surface is cleaner and smoother, which is conducive to the full bonding between the metals during welding. This can improve the strength and reliability of the weld and ensure the safe use of the welded structure. Through the cooperation of the third gear and the second rotating shaft, the blades can stir the detergent in the storage box to avoid the precipitation of the detergent.

[0016] 2. Through the cooperation between the buffer box and the argon tank, the exhaust pipe can output argon gas around the weld. The airflow can quickly dry the cleaning agent left around the weld, and can also clean the impurities missed in the fixed teeth. The output of argon gas through the exhaust pipe can protect the metal from oxidation during welding. The exhaust pipe can be heated by the heating tube to heat the argon gas. The heated argon gas can cover the welding area more evenly, thereby improving the welding quality. Through the cooperation between the fourth electric telescopic rod and the second welding head, spot welding can be performed before welding the weld, so that the connection between the arc window frames is more stable, avoiding displacement during full welding.

[0017] 3. Through the cooperation between the third motor and the fifth gear, the fifth gear can be engaged with the fixed teeth to drive the arc window frame to move, so as to adjust the position of the arc window frame before welding. After a group of welds are completed, the third motor drives the fifth gear to rotate, so that the arc window frame is clamped by the clamping block, and the fifth gear drives the arc window frame to move through the fixed teeth, so that the arc window frame rotates 90 degrees in the same direction and switches to the next group of welds, thereby improving welding efficiency and reducing manual operation. Through the cooperation between the ball bearing and the assembly groove, the friction between the arc window frame and the clamping block can be reduced when the arc window frame moves, thereby avoiding additional scratches on the arc window frame.

When the output shaft of the third electric telescopic rod 321 is output, the feeding pipe 325 is driven to move synchronously through the second connecting plate 324. When the feeding pipe 325 moves, the feeding hole 326 is brought into the detergent box 316.

After completion, the second motor 314 is stopped, and then the arc-shaped soft brush 322 is driven to reset through the third electric telescopic rod 321; The valve at the lower end of the argon tank 42 is opened to discharge the argon gas into the buffer box 41, and then enter the exhaust pipe 43 through the buffer box 41, and the heating cylinder 44 is started to heat the exhaust pipe 43, so that the heated argon gas is discharged to the outside through the exhaust pipe 43, so that the cleaning agent around the weld is quickly dried, and the air flow is used to clean the remaining impurities, and the weld is filled with argon gas. The high temperature can also preheat the arc window frame 7. When the argon temperature is too high, the heating temperature of the heating cylinder 44 is reduced, and the fan 46 is started. The fan 46 discharges the hot air flow outward through the vent 45 to prevent the argon temperature from being too high. Then the second electric telescopic rod 311 is started, and the second electric telescopic rod 311 drives the first welding head 312 through the first connecting plate 312. 10 is close to the weld, and then the welding machine box 39 is started to start welding the weld. Argon gas can prevent the weld from being oxidized again. The C-shaped rotating plate 36 drives the first welding head 310 to weld around the weld of the arc window frame 7, and adjusts the distance between the first welding head 310 and the weld by the second electric telescopic rod 311, so as to weld the weld in the assembly groove 8 so that the weld is fully welded. After a group of welds is completed, the third motor 62 is started again, and the third motor 62 drives the fifth gear 64 to rotate, so that the four groups of arc window frames 7 are clamped by the clamping block 61, and the fifth gear 64 drives the arc window frames 7 to move through the fixed clamping tooth 9, so that the four groups of arc window frames 7 are rotated ninety degrees in the same direction to switch to the next group of welds.
