[0031] The plate structure is hoisted and moved above the side position cushion shaft 101 on both sides of the platform, and the plate structure is supported by the plate supporting roller 1011 on the surface of the side position cushion shaft 101. The plate supporting roller 1011 can effectively reduce the frictional resistance between the plate and the platform, so that the plate structure can be moved between the supporting leg assembly 6 and the pressing plate assembly 3 by manual pushing, and then the plate structure with an arc is pressed against the outside of the supporting leg assembly 6 by the contraction of the pressing plate assembly 3, so as to keep it in a horizontal state and complete the clamping and fixing operation. Then the blade automatically cuts the side surface of the plate by the blade automatic cutting assembly 5, and the blade automatically cuts the plate from one end to the other end of the track plate 4 at a constant speed. After single-sided cutting, the blade angle is turned to cut the plate again from the inside;

[0032] The waste generated during the cutting process can fall into the center plate groove 102 area on the surface of the processing platform 1 through the reserved slag hole 401 on the surface of the track plate 4, so as to avoid a large amount of waste accumulated on the surface of the track plate 4, thereby affecting the travel operation of the blade automatic cutting assembly 5.

The back-shaped connecting rod 303 connected to the ground can be retracted inward and extended outward by the gear push groove 1012. The extension of the back-shaped connecting rod 303 can make the metal pressing plate 301 adhere to the structure of the plate with an arc. With the retraction of the back-shaped connecting rod 303, the arc is gradually flattened. At this time, the two sides of the plate are in contact with the metal pressing plate 301 and the metal back plate 601 respectively. After cutting, the back-shaped connecting rod 303 extends outward to release the clamping operation of the metal pressing plate 301 on the plate structure.
