[0002] Maglev train is the direction of high-speed traffic development in the future. It has the advantages of fast speed, less 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 suffers from uneven rolling force during the rolling process and uneven stress generated during the cooling process. Cooling deformation is easy to occur in the rolling direction, which affects the use of the next process; at present, there is no special low-temperature straightening device for F-shaped steel. In the past, only jacks were used for straightening. Design a special device for steel straightening

The invention provides an F-shaped door frame channel steel straightening device. The straightening device comprises a base plate, a fixed side pressing plate, an upper pressing plate, a movable side pressing plate and a driving device. The base plate is a flat plate placed horizontally. The fixed side pressing plate is vertically arranged on the upper surface of one end of the base plate. One end of the upper pressing plate is connected with the top end of the fixed side pressing plate, and the other end of the upper pressing plate extends toward the other end of the base plate. The driving device is arranged on the upper surface of the other end of the base plate. A piston rod of the driving device extends toward one end of the base plate. The end of the piston rod is connected with the movable side pressing plate and can drive the movable side pressing plate to move. The upper surface of the base plate, one side face of the fixed side pressing plate, the lower surface of the upper pressing plate and one side face of the movable side pressing plate jointly surround the outer side face of F-shaped door frame channel steel. According to the F-shaped door frame channel steel straightening device, the special-shaped steel can be straightened comprehensively and precisely.
Description
technical field [0001] The invention relates to the field of deep processing of steel materials, in particular to the field of plastic shaping of special-shaped steel materials. It is an F-shaped gantry channel 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] The maglev train is the direction of high-speed traffic development in the future. It has the advantages of fast speed, less 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. After passing through the hot straightening machine, due to the uneven and incomplete stress relief, the F-shaped...
