Description

Technical Field

[0001] This invention relates to the field of steel bar processing technology, and more particularly to an automatic steel mesh welding production equipment. Background Technology

[0002] A box girder is a type of beam used in bridge engineering. It is hollow inside and has flanges on both sides of the upper part, resembling a box, hence the name.

[0003] The edges of the box girder are solid, while the interior is hollow. The hollow interior reduces the production and transportation costs of the box girder. However, the hollow structure concentrates the stress on the edges of the box girder. Therefore, the edges of the solid structure generally require a large number of steel bars to form a steel mesh for support. Since the external structure of the box girder is generally U-shaped, the steel mesh supporting the box girder is generally formed by welding U-shaped ring steel bars and longitudinal steel bars perpendicular to the U-shaped plane.

[0004] When assembling U-shaped steel mesh for box girder support, manual or semi-automatic welding equipment is often required to weld the connection points of straight steel bars and U-shaped ring steel bars one by one, resulting in low production efficiency of U-shaped steel mesh for box girder support. At the same time, the welding points are welded one by one during the assembly of U-shaped steel mesh for box girder support, resulting in poor consistency in different parts of the steel mesh; and continuous production is not possible, making it unsuitable for large-scale production.

[0005] In conclusion, there is an urgent need for an automated steel mesh welding production line to solve the aforementioned problems. Summary of the Invention

This equipment solves the problem that the assembly of U-shaped steel mesh for box girder supports often requires manual or semi-automatic welding equipment to weld the connection points of straight steel bars and U-shaped ring steel bars one by one. This results in low production efficiency of U-shaped steel mesh for box girder supports, failing to meet usage requirements.
