Description

Technical Field

[0001] The utility model relates to an alignment device, in particular to an alignment device for welding, and belongs to the technical field of section steel production. Background Art

[0002] Steel sections are strips of steel with a specific cross-sectional shape and size, and are one of the four major types of steel (plates, tubes, sections, and wires). Based on the cross-sectional shape, steel sections are divided into simple section steel sections and complex section steel sections (special-shaped steel sections). The former refers to square steel, round steel, flat steel, angle steel, hexagonal steel, etc.; the latter refers to I-beams, channels, rails, window frame steel, curved sections, etc. The main production processes of steel sections include loading, uncoiling, leveling, head and tail shearing, butt welding, forming, shearing, unloading, and stacking. To maintain continuous production of steel sections, different coils of steel need to be butt-jointed head and tail.

[0003] During the butt welding process of steel, the head and tail of the sheared steel need to be spliced ​​together. However, the existing butt welding table can only achieve head and tail splicing. During splicing, the two pieces of steel are easily misaligned, so that the two pieces of steel are in an inclined butt-jointed state, that is, the two pieces of steel are not on the same center line, so that the steel after butt welding has a folded angle at the splicing point, affecting the straightness of the steel section and causing the quality of the finished steel section to be reduced.

[0004] Therefore, a welding alignment device is proposed. Utility Model Content
