The method includes the following steps: separately forming a first vertical wall and a first horizontal wall connected to each other at two opposite ends of a to-be-machined plate; rolling and bending the first horizontal wall to form a stepped bent structure; rolling and bending the first horizontal wall to form a second vertical wall, a second horizontal wall, and a third horizontal wall; rolling and bending the second horizontal wall to form a third vertical wall and a fourth horizontal wall; rolling and bending the third horizontal wall to form a fourth vertical wall and a fifth horizontal wall; performing laser welding on a joint of the fourth vertical wall and the first vertical wall; rolling and bending one end of the fifth horizontal wall away from the fourth vertical wall to form a connecting edge and a sixth horizontal wall; rolling and bending the sixth horizontal wall to form a fifth vertical wall and a seventh horizontal wall; and performing laser welding on a joint of the connecting edge and the second vertical wall.",
