Embodiment 1
[0016] A method for making a hyperboloid H-shaped steel in this embodiment includes the following steps: 1) re-inspection of incoming materials for the horizontal plate, flat plate of the horizontal plate, and pretreatment; wired type, such as figure 1 as shown, figure 1 The middle web 11, the upper flange plate 12, and the lower flange plate 13; most of the straight H-shaped steels usually produced are assembled by the assembly machine, but this kind of H-shaped steel cannot be assembled on the assembly machine due to the complex and changeable line shape. Finish. 2) In order to ensure the manufacturing accuracy of hyperboloid H-shaped steel, computer CAD three-dimensional lofting is adopted to establish a three-dimensional coordinate system, and the web 11 and flange plates (upper flange plate 12 and lower flange plate 13) of the curved H-shaped steel are planar Expand; 3) Cut and blank the expanded flange plate (upper flange plate 12, lower flange plate 13) and web 11 on ...
