[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 gantry channel steel currently produced is C160. Because the section of the special-shaped steel is not evenly distributed, the steel is not uniformly stressed during rolling, and the length is divided into different parts. After cutting, the steel is affected by the cooling stress and causes cooling side bending. In order to ensure the processing accuracy of the steel, it is necessary to correct the steel; currently there is no special correction device for the door frame channel steel. In the past, only the jack was used for correction. The accuracy of this correction method is not high. High, it is easy to cause secondary damage to the steel, so it is necessary to design a special device for door frame channel steel correction

The invention provides a C-shaped portal frame steel channel correcting device. A first vertical plate is vertically arranged on a base plate, and the top end of the first vertical plate is connected with one end of an L-shaped overturning upper pressing plate through an overturning shaft. The upper surface of the base plate, the right surface of the first vertical plate and the inner surface of the L-shaped overturning upper pressing plate surround the outer side face of a C-shaped portal frame steel channel together. A second vertical plate is vertically arranged on the base plate, and the top end of the second vertical plate is connected with the end of a rectangular overturning side pressing plate through an overturning shaft. Three side surfaces of the rectangular overturning side pressing plate are in butt joint with the inner side face of the C-shaped portal frame steel channel. Two driving devices are connected with the L-shaped overturning upper pressing plate and the rectangular overturning side pressing plate correspondingly. Both the L-shaped overturning upper pressing plate and the rectangular overturning side pressing plate can be driven by the driving devices to be moved and overturned. By means of the C-shaped portal frame steel channel correcting device, special-shaped steel can be corrected comprehensively and accurately.
Description
technical field [0001] The invention relates to the field of deep processing of steel, in particular to the field of shaping of special-shaped steel. Background technique [0002] The gantry channel steel is a special-shaped steel used for the lifting of the forklift in the production of forklifts. The gantry channel steel currently produced is mainly C160. Because the section of the special-shaped steel is not evenly distributed, the steel is subjected to uneven force during rolling, and it is divided into fixed lengths. After cutting, the steel is affected by the cooling stress and causes cooling side bending. In order to ensure the processing accuracy of the steel, it is necessary to correct the steel. At present, there is no special gantry channel correction device. In the past, only the jack was used for correction. This correction method has poor accuracy. High, it is easy to cause secondary damage to the steel, so it is necessary to design a special device to straight...
