When processing the door and window frames of the same batch of specifications, first adjust the distance between the two cutting devices 13 according to the length or width of the door and window frames. The specific adjustment method is as follows: by starting the sliding mechanism, the sliding mechanism drives the mobile platform 5 to move until the mobile platform 5 is adjusted to a suitable position. During the sliding process of the mobile platform 5, the mobile platform 5 drives the telescopic mechanism to change the length. Then, the aluminum alloy to be cut is placed on the top plate of the fixed platform 1 and the mobile platform 5, and the limiting mechanism is started to press the aluminum alloy to be cut. Finally, start the two cutting devices 13, and the two cutting devices 13 can cut both ends of the aluminum alloy at the same time.

[0021] Please refer to Figure 1 , Figure 2 and Figure 3 The sliding mechanism includes two guide rails 6 arranged front and back, and a slider 10 is slidably connected to the inner wall of the guide rail 6.
