[0028] During the use of the present invention, firstly, the corresponding forming module 21 and extrusion module 15 are selected according to the needs, and then the forming module 21 is placed on the inner wall of the lower end of the working frame 1, and then the threaded rod 19 can be rotated, and then the threaded connection between the threaded rod 19 and the moving seat 18 makes the moving seat 18 slide in the moving groove 17, and then the clamping seat 20 is driven to approach the fixed seat 16 and clamp the forming module 21, and then the fixing bolt 12 can pass through the mounting hole 11 and be connected with the fixing nut 14 to complete the fixing work between the connecting plate 13 and the mounting plate 10, and then the installation and fixing work of the extrusion module 15 is successfully completed, and then the telescopic motor 6 can be controlled by the relative position of the extrusion module 15 and the forming module 21, and then the telescopic shaft 7 can drive the sliding seat 5 to slide to the specified position in the sliding port 2, and at the same time, the extrusion module 15 and the forming module 21 are aligned, so that the user can complete the replacement of different styles of extrusion modules 15 and forming modules 21, and then the magnesium-aluminum alloy material can be subjected to different styles of extrusion molding processing, which greatly meets the different usage needs of users;

[0029] Then the user can place one end of the longer magnesium-aluminum alloy material on the forming module 21. At this time, the two side walls of the magnesium-aluminum alloy material will be respectively attached to the conveyor belt 25 and the multiple auxiliary wheels 35. At this time, the working motor 26 will control the rotation of the rotating shaft 23 and the rotating roller 24, and then the conveyor belt 25 will rotate. The rotating conveyor belt 25 can drive the magnesium-aluminum alloy material to move by virtue of the friction between itself and the magnesium-aluminum alloy material. At the same time, the hydraulic cylinder 8 will control the hydraulic column 9 to push the mounting plate 10 down and up, and then push the connecting plate 13 and the extrusion module 15 to approach and move away from the forming module 21. In this way, the extrusion module 15 can cooperate with the forming module 21 to complete the extrusion molding work of the magnesium-aluminum alloy material. With the help of the conveyor belt 25 to drive the movement of the magnesium-aluminum alloy material, the continuous extrusion processing of the magnesium-aluminum alloy material can be smoothly completed. The staff no longer needs to frequently load and unload the magnesium-aluminum alloy material, which greatly improves the product production efficiency. At the same time, the movement of the magnesium-aluminum alloy material does not require the participation of the staff, which greatly ensures the safety of the staff during the extrusion work.
