Abstract

The invention provides a B-type gantry steel channel rolling type low-temperature correcting device. The correcting device comprises an upper correcting portion for correcting a flange and a supporting flange of a B-type gantry steel channel, a lower correcting portion located below the upper correcting portion and used for correcting the flange and the supporting flange of the B-type gantry steelchannel and a side correcting portion connected to the lower correcting portion and used for correcting a web plate and the supporting flange of the B-type gantry steel channel. The upper correctingportion includes an upper frame, an upper correcting roller and a flange upper roller; the upper correcting roller and the flange upper roller are both disposed on the upper frame; the flange upper roller is located on the lower side of the upper correcting roller; and the side correction portion includes a base and a side correcting roller, the base is disposed on a lower frame, and the side correcting roller is disposed on the base. The B-type gantry steel channel rolling type low-temperature correcting device can correct the web plate, the flange and the supporting flange of the B-type steel channel while the B-type steel channel is driven by a lower correcting roller to slide smoothly forward.

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 correction device for channel steel of a B-shaped gantry. Background technique [0002] The gantry channel steel is a special-shaped steel used for the lifting and lowering of the forklift in the production of forklifts. The main model of the gantry channel steel currently produced is B200. Because the section of the special-shaped steel is not evenly distributed, the steel is not uniformly stressed during rolling, and the length After slitting, the steel is affected by the cooling stress and causes cooling side bending. In order to ensure the processing accuracy of the steel, the steel needs to be corrected. [0003] At present, there is no special straightening device for special-shaped steel. In the past, only jacks were used for straightening. This kind of straightening method is not high in accuracy and is...
