It should be noted that: the connecting ribs 36 are the remaining parts of the section bar after cutting off the redundant connecting parts between the four columns 34 and the inclined rods 35; this is similar to an apple net, with the excess cut away and the remaining portion forming the tie bars 36, which stretch its four posts 34 through the interior of the profile so that the diagonal bars 35 form a grid-like shape between the

posts

34 and 34 of the profile, the resulting one-piece lattice post being shown with reference to figure 2. The shape of the diagonal rod 35 on the cylindrical surface of the profile is not limited to the one shown in fig. 2, and other shapes can be designed, for example, redundant connecting parts between the four columns 34 of the profile and the diagonal rod 35 and between the diagonal rod 35 and the diagonal rod 35 are cut off, so that the diagonal rod 35 and the four columns 34 of the profile and between the diagonal rod 35 and the diagonal rod 35 are connected through connecting ribs 36, as shown in fig. 3; drawing into the final monolithic lattice column is shown with reference to figure 4.

After the integral latticed column is processed, the first air cylinder 7 and the second air cylinder 8 are restored to the original state, and the spring column 33 restores the inner die 6 to the original state due to the restoration of the elastic force. Specifically, the method comprises the following steps: the spring columns 33 are installed before the first cylinder 7 and the second cylinder 8 are operated, and the inner mold 6 is restored to an original state by the deformation of the spring columns 33.

Further, the first movable plate 14 and the second movable plate 15 may be simultaneously pushed into the inner mold 6, pushing the first movable plate 14 and the second movable plate 15 by default the first cylindrical drum 9 and the second cylindrical drum 11 have been mounted thereon.
