Description

Technical Field

[0001] This utility model relates to the field of pipeline welding, specifically a multifunctional angle iron flange welding device. Background Technology

[0002] Angle iron flanges are commonly used components for duct connections, made of angle steel or angle iron, and are typically used in applications requiring high strength and sealing. They feature high strength (suitable for high-pressure environments, capable of withstanding 2000 Pa pressure), good stability (strong resistance to deformation, especially performing well under high wind pressure), good sealing (using double-layer sealant and high-precision bolts, resulting in low air leakage), and durability (mostly made of stainless steel or carbon steel, corrosion-resistant, and with a long service life).

[0003] When welding angle iron flanges to welded pipes, both angle iron flanges and welded pipes are in a movable state, which makes them prone to misalignment during welding, affecting the welding accuracy between them. In addition, the angle iron flanges need to be manually flipped to change the welding surface during welding, which is not only laborious but also affects welding efficiency. To solve the above problems, this application proposes a multifunctional angle iron flange welding device. Utility Model Content

[0030] It should be noted that matching the spacing between the limiting clamps 3 with the diameter of the angle iron flange and using the fixing clamp 6 to clamp the angle iron flange facilitates quick fixation of the angle iron flange. The end of the welded pipe is supported by the third guide roller 14 and aligned with the angle iron flange, which can position the welded pipe and the angle iron flange, improving the welding accuracy and efficiency between the angle iron flange and the welded pipe. The two ends of the third guide roller 14 are slidably connected to the welded pipe guide frame 13 through the guide seat 15, and the height of the third guide roller 14 can be flexibly adjusted according to the diameter of the welded pipe during use. After the fixing clamp 6 is released, the first guide roller 4 is driven by the drive motor 16, and the second guide roller 5 guides the angle iron flange on both sides, allowing the angle iron flange to rotate. This facilitates adjustment of the welding surface during welding and improves the welding efficiency of the angle iron flange.
