Embodiment Construction

[0036] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0037] The embodiment of the present invention provides a method for straightening T-shaped steel, in which flame straightening is performed on T-shaped steel in the assembly line welding operation of T-shaped steel, including:

[0038] Adjust the height of the flame heating gun according to the height of the T-shaped steel;

[0039] Since the T-shaped steel is processed from the right-angled area formed by the bottom of the web and the top of the wing, double-sided welding is carried out. Since the height of the web of different types of T-shaped steel is different, adjust the flame according to the height of the T-shaped steel. The height of the heat gun heats the top of the web, which ...

Abstract

The invention relates to the technical field of welding, in particular to a T-shaped steel machining device and a T-shaped steel straightening method. According to the T-shaped steel straightening method, flame straightening is conducted on T-shaped steel during assembly line welding operation of the T-shaped steel. The T-shaped steel straightening method comprises the following steps that the height of a flame heating gun is adjusted according to the height of the T-shaped steel; the T-shaped steel is welded; when the initial end of a weld joint of the T-shaped steel is aligned to the straightening device, the flame heating gun needing to work is started; and when the terminal end of the weld joint of the T-shaped steel is aligned to the straightening device, the started flame heating gun is stopped. By the adoption of the T-shaped steel machining device and the T-shaped steel straightening method, the straightening time can be effectively shortened, the production efficiency of the T-shaped steel is improved, an assembly line is prevented from being stopped, and the utilization rate of a machining plant is increased.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a T-shaped steel processing device and a T-shaped steel correction method. Background technique [0002] At present, the T-shaped steel structure has been widely used in the fields of hydropower station construction and factory building construction. However, during the production process of the T-shaped steel, due to the excessive local heating of the weld, the T-shaped steel will be deformed during the welding process. If the problem occurs, if the welding deformation is not corrected, it will not only affect the installation of the overall structure, but also reduce the safety and reliability of the project. [0003] The existing T-shaped steel welding deformation correction work is to adopt pyrotechnic correction after the completion of the processing line, that is, to carry out thermal deformation treatment on the T-shaped steel, but this correction method has the following...
