[0040] Support block 3 is located on the lower side of the color steel tile body 1 and can slide in the groove on the color steel tile body 1. Several support blocks 3 are evenly located on the left and right sides of the cutting machine 10.

[0041] Adjustment unit 7 is located between support block 3 and platform 2. Adjustment unit 7 includes mounting block 71, with a limiting block 72 fixed to its lower side. Support block 3 is mounted on top of mounting block 71. Platform 2 has two T-slots on its upper side, allowing mounting block 71 and limiting block 72 to slide within them. Mounting block 71 has two threaded holes, with blind holes above them. Limiting block 72 has two threaded holes, connected to the blind holes. A positioning bolt 73 is located inside the blind hole, engaging with the threaded holes. Adjustment unit 71 allows for adjustment of the mounting block 71. The position of the A limiting block 72 in the T-slot is adjusted to change the position of the A support block 3 on the platform 2. When the A support block 3 is adjusted to the appropriate position on the platform 2, the A positioning bolt 73 is tightened so that it is pressed against the T-slot, making the A mounting block 71 and the A limiting block 72 unable to move. The A support block 3 can be replaced with a corresponding shape as needed to adapt to different shapes and sizes of color steel tile bodies 1, improving the applicability of the device. The A support block 3 is located in the groove on the lower side of the color steel tile body 1, which plays a role in positioning and supporting the color steel tile body 1. When the color steel tile body 1 is cut, the probability of the color steel tile body 1 shaking is reduced, and the processing quality is improved.

According to the height of the main body 1 of the color steel tile, the corresponding lifting plate 81 is replaced so that the lifting plate 81 is not easily deformed when pressing the main body 1 of the color steel tile, which improves the stability of the lifting plate 81. The electric push rod 82 can slide the lifting plate 81 in the sliding groove on the support plate 83. The lifting plate 81 moves together with the B support block 4 through the adjustment part 86 mentioned below, so that the lifting plate 81 can press on the main body 1 of the color steel tile and let the B support block 4 enter the groove on the main body 1 of the color steel tile, which can play a positioning role for the main body 1 of the color steel tile. When the main body 1 of the color steel tile is cut, the probability of the main body 1 of the color steel tile shaking is reduced, and the processing quality is improved.

The B positioning bolt 863 and the B limiting block 862 are located on the upper side of the lifting plate 81. By adjusting... The position of the sliding block 861 within the sliding hole B allows the sliding block 861 to move together with the B limiting block 862 and the B support block 4. After the B support block 4 moves to the appropriate position, it can be replaced with a corresponding shape according to the requirements, which can adapt to the color steel tile body 1 of different shapes and sizes, thus improving the applicability of the device. Furthermore, the B support block 4 plays a role in positioning and supporting the color steel tile body 1, reducing the probability of the color steel tile body 1 shaking during the cutting process and improving the processing quality.
