Abstract

The invention provides a rolling type low-temperature correction device of F-shaped steel. The correction device comprises an upper correction portion, a lower correction portion and a tail flange correction portion. The upper correction portion is used for correcting a web and a second leg flange of the F-shaped door frame channel steel. The lower correction portion is located below the upper correction portion and is used for correcting the web and a first leg flange of the F-shaped door frame channel steel. The lower correction portion comprises a lower frame, a sleeve and lower correctionrollers. The tail flange correction portion is connected to the lower correction portion and is used for correcting a tail flange of the F-shaped door frame channel steel. According to the rolling type low-temperature correction device of the F-shaped steel, space matched with the F-shaped door frame channel steel is formed by upper correction rollers, upper flange rollers, lower flange rollers, side correction rollers and the lower correction rollers, the F-shaped channel steel is driven by the lower correction roller to smoothly slide forwards, and meanwhile the web, the tail flange, the first leg flange and the second leg flange are corrected.

Description

technical field [0001] The invention belongs to the field of plastic shaping of special-shaped steel materials, and in particular relates to a rolling low-temperature straightening device for F-shaped steel. Background technique [0002] The maglev train is the direction of high-speed traffic development in the future. It has the advantages of fast speed, low energy consumption, and less pollution. In the maglev train operating system, the roller table made of F-shaped steel is an important part and the most difficult part to process ; As a special-shaped steel, F-shaped steel is subjected to uneven rolling force during the rolling process, and the stress generated during the cooling process is uneven. Cooling deformation is easy to occur in the rolling direction, which affects the use of the next process; currently there is no special low-temperature straightening device for F steel, and only a jack is used for straightening in the past, but this kind of straightening metho...
