Description

Technical Field

[0001] The utility model belongs to the technical field of processing and correction, and in particular relates to a correction component of a cross steel column. Background Art

[0002] During the manufacturing process of the cross steel column, two smaller side steel plates need to be welded in the middle of a wider whole steel plate to form a cross shape. However, during the welding process, the wider whole steel plate often undergoes local bending and deformation due to the high welding temperature, and it is difficult to directly correct the deformation during welding.

[0003] In the prior art, the patent document with the announcement number CN201210225488.9 discloses a method for flame correction of cross steel after welding deformation, which uses flame correction at a temperature not exceeding 800°C, including linear heating method, point heating method and triangle heating method for correction. The above correction scheme not only has high requirements on the processing technology, but also uses high-temperature flame correction, which wastes energy and easily causes uncontrollable changes in the material properties of the cross steel column itself, which may result in failure to meet the requirements of the use strength.
