Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0024] Wherein, the two groups of adsorption tubes 36 are both configured as U-shaped structures.

[0025] Wherein, both ends of the two groups of adsorption tubes 36 are provided with adsorption heads 361 , and adsorption holes are opened on the adsorption heads 361 .

[0026] Before the flame cutting frame 2 starts cutting, the cylinder 32 drives the air pipe 33 to move upward, the air pipe 33 drives the second air pipe 35 to move upward, and the second air pipe 35 drives the two groups of adsorption tubes 36 to move upward, so that the adsorption heads 361 of the two groups of adsorption tubes 36 contact the lower end surface of the plate body 5;

[0028] The two groups of adsorption tubes 36 are respectively located on both sides of the plate body 5 to be cut. When the flame cutting head 21 of the flame cutting frame 2 cuts the plate body 5, the two groups of adsorption tubes 36 are used to limit the plate body 5, so as to overcome the thermal stress generated during the cutting process, thereby avoiding the plate body 5 from warping and deformation during the flame cutting process, and improving the flame cutting quality.
