Problems solved by technology

[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 J200. Since the cross-section of the special-shaped steel is not evenly distributed, the steel is not uniformly stressed during rolling, and the length is divided. 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 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

Abstract

The invention provides a J-shaped portal frame channel steel correcting device. The J-shaped portal frame channel steel correcting device comprises a supporting frame, an overturning side pressing plate, an overturning shaft, a vertical rod and a driving device, wherein a J-shaped portal frame channel steel, the vertical rod and the driving device are respectively and fixedly connected with the supporting frame; the vertical rod is vertically arranged on the supporting frame; the top end of the vertical rod is connected with the end part of the overturning side pressing plate by the overturning shaft; three side surfaces of the overturning side pressing plate are propped against the inner side surfaces of the J-shaped portal frame channel steel; the driving device is vertically arranged on the supporting frame, and is connected with the overturning side pressing plate; and the overturning side pressing plate can move and overturn under the driving of the driving device. The J-shaped portal frame channel steel correcting device disclosed by the invention can comprehensively and accurately correct irregular-shaped steel materials.

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 a J-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 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 J200. Since the cross-section of the special-shaped steel is not evenly distributed, the steel is not uniformly stressed during rolling, and the length is divided. 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 correction device fo...
