Description

Technical Field

[0001] This utility model belongs to the field of steel pipe production technology, specifically relating to a burr swing knife adjustment mechanism in a welded pipe unit. Background Technology

[0002] A welded pipe production line is a type of equipment used to produce welded steel pipes by rolling steel strips or plates into shape and welding them into tubular sections. The line typically includes main components such as an uncoiler, forming machine, welding machine, sizing machine, cutting machine, and straightening machine. Welded pipe production lines can efficiently and continuously produce welded steel pipes of various specifications and materials, and are widely used in petroleum, natural gas, construction, and machinery manufacturing industries. Their production process is highly automated, and product quality is stable, making them an indispensable piece of equipment in modern industrial production.

[0003] Burrs on the inner wall of welded steel pipes are formed by the melting and cooling of metal during the welding process. These burrs increase the roughness of the pipe's inner wall and increase fluid resistance. Therefore, a burr adjustment mechanism is needed within the welded steel pipe unit to scrape off the burrs. Conventional burr adjustment mechanisms cannot be adapted to different sizes and heights of welded steel pipes and require manual tool replacement, which is cumbersome. To address this, we propose a burr adjustment mechanism for welded steel pipe units. Utility Model Content
