Description

Technical Field

[0001] The utility model relates to the technical field of steel profile processing, in particular to an adjustable clamp for fine steel profiles. Background Art

[0002] Due to the current considerable development prospects of refined steel profiles (refined steel) in China and the accumulation of certain technologies, and with the development of the construction industry, the demand for curtain wall systems in large-scale construction projects continues to grow, especially for buildings with large spans and large spaces. Refined steel curtain wall systems are favored because they can meet these needs. The country's policies on energy conservation, emission reduction, and green buildings also support the targeted demand for refined steel in some landmark construction projects. As the world's largest producer and consumer of glass curtain walls, China's curtain wall industry has great potential in the international market. Despite fierce market competition, competition within the industry is gradually developing towards refined services, engineering design capabilities, management, and innovation capabilities.

[0003] Delicate steel profiles need to be fixed, flipped and adjusted in order to adjust the angle of the delicate steel profiles during cutting or welding. However, since delicate steel profiles usually have a large cross-section and are heavy, relying solely on manual fixation of the delicate steel profiles results in poor stability, easy shaking and movement. In addition, the traditional manual flipping of delicate steel profiles is laborious, and manual flipping is prone to uneven force on both sides of the cut or weld, causing the cut to tear or the weld to crack, thus affecting the normal cutting or welding of the delicate steel profiles.
