[0002] H-shaped steel is the main steel used in steel structure buildings at present. The H-shaped steel produced at present has a complete range of specifications, especially the larger-sized H-shaped steel is prone to side bending when cooling. After cutting to length, the steel is affected by the cooling stress. Bending is not easy to eliminate. In order to ensure the processing accuracy of steel, it is necessary to correct the steel. At present, there is no special straightening device for H-shaped steel. In the past, only jacks were used for straightening. This straightening method is not high in accuracy and is easy to cause secondary damage to steel , so it is necessary to design a special device for steel correction

The invention provides an H-shaped steel correcting device. The device comprises a baseplate, a fixed frame, a movable frame and a first hydraulic cylinder, wherein a projection with a rectangular section is arranged on the baseplate; the rectangular projection is used for butting against one side surface of a web plate of H-shaped steel; the fixed frame is integrally F-shaped, and consists of an upper horizontal plate, a lower horizontal plate and a vertical plate; the upper horizontal plate and the lower horizontal plate are both connected to the same side of the vertical plate; the bottom end of the vertical plate is connected to the upper surface of the baseplate; a space defined by the lower surface of the lower horizontal plate, the right side surface of the vertical plate and the upper surface of the baseplate is used for accommodating one flange of the H-shaped steel; a piston rod of the first hydraulic cylinder is connected with the movable frame through a push rod; and a space in the movable frame is used for accommodating the other flange of the H-shaped steel. The device can comprehensively and precisely correct special-shaped steel.
Description
technical field [0001] The invention relates to the field of deep processing of steel materials, in particular to the field of shaping of special-shaped steel materials. It is an H-shaped steel straightening device, which belongs to a brand-new special tool and can improve the shaping accuracy and work efficiency of special-shaped steel materials. Background technique [0002] H-shaped steel is the main steel used in steel structure buildings at present. The H-shaped steel produced at present has a complete range of specifications, especially the larger-sized H-shaped steel is prone to side bending when cooling. After cutting to length, the steel is affected by the cooling stress. Bending is not easy to eliminate. In order to ensure the processing accuracy of steel, it is necessary to correct the steel. At present, there is no special straightening device for H-shaped steel. In the past, only jacks were used for straightening. This straightening method is not high in accuracy...
