Embodiment Construction
[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but these embodiments should not be construed as limiting the present invention.
[0029] An H-shaped steel flange correction device shown in the figure includes a correction tool 4, an H-shaped steel 5 and a hydraulic mold 3. Hydraulic mold 3 is made of T-shaped die 3a made of two steel plates and two balance steel plates 3b that are welded horizontally and vertically symmetrically on both sides in the middle of T-shaped die 3a; the middle of the upper end of T-shaped die 3a is connected with hydraulic press 1 image 3 shown); the control end of the hydraulic machine 1 is electrically connected with the operating platform 2 (as figure 2 shown);
[0030] The correction tool 4 is made of a large steel plate 4a placed horizontally, a pillar steel plate 4b welded horizontally and vertically in the center of the large steel plate 4a, and ...

Abstract
The invention discloses a using method of an H-steel flange correction device. The using method comprises the following steps that 1, deformed H-steel is stably inserted into a correction hole of a correction tool to ensure that the upper flange of the H-steel is stably arranged on two small steel plates, a web plate of the H-steel and a vertical steel plate of a T-shaped die are located on the same plane; 2, energization is performed, a hydraulic machine is controlled through an operating platform, the height of the hydraulic machine is adjusted according to the welding deformation situation of the H-steel to enable the vertical steel plate of the T-shaped die to be in contact with the upper surface of the H-steel; 3, the hydraulic machine is controlled through the operating platform, hydraulic strength is adjusted, and the web flange of the H-steel is repeatedly corrected. The H-steel flange correction device is convenient to operate. By means of the using method, narrow-flange H-steel and wide-flange H-steel and can be subjected to flange correction.
Description
technical field [0001] The invention relates to an H-shaped steel correction device, in particular to an H-shaped steel flange correction device, and the invention also includes a method for using the device. Background technique [0002] After the H-shaped steel has completed the welding process, the wing plate of the H-shaped steel will be deformed under the action of welding stress (such as figure 1 shown), therefore, the H-beam must be calibrated by the H-beam flange straightening machine before it can be used after the welding process is completed. [0003] With the in-depth development of the steel structure industry, the use method of the H-shaped steel flange correction device has gradually entered the historical stage of the steel structure industry, and has been widely used and promoted. [0004] However, the use method of the existing H-shaped steel flange correcting device has restrictions on the width of the H-shaped steel flange, and neither the narrow-flange ...
