[0021] The inner wall of the heating box 1 is a hollow structure;

[0022] Specifically, in the present embodiment, a heating box 1 is designed, and a plurality of staggered heating plates 3 are installed inside the box. These heating plates 3 improve the heating effect by being evenly distributed, ensuring that the temperature distribution of the aluminum ingot during the heating process is more uniform. The inner wall of the heating box 1 is a hollow structure, which can effectively retain heat, reduce heat loss, and optimize the heating efficiency. An auxiliary material addition port 2 is provided on one side of the heating box 1, which can timely add auxiliary agents or other auxiliary materials during the heating process, thereby improving the processing performance of the aluminum ingot and avoiding brittle cracking or poor processing of the aluminum material due to too low heating temperature. The extrusion structure is connected to the side of the heating box 1 away from the auxiliary material addition port 2 to ensure the stability of the aluminum alloy during the extrusion process.

[0023] Embodiment 2: The feeding structure comprises an outer feeding barrel, which is arranged on the upper side of the heating box 1, an inner feeding barrel 9 is installed inside the outer feeding barrel 5, a feeding hopper 6 is inserted on the outer feeding barrel 5, the feeding hopper 6 is connected with the inner feeding barrel, and is located on the side close to the auxiliary material inlet, the inner cavity of the inner feeding barrel is connected with the inner cavity of the heating box 1, a rotating rod 7 is rotatably installed in the inner feeding barrel 9, and spiral blades are evenly arranged on the outer annular surface of the rotating rod 7, a first motor 8 is installed on the outer side of the outer feeding barrel 5, and the rotating end of the first motor 8 is connected with the rotating rod 7;

[0024] Specifically, the feeding structure adopts a double-layer design of an outer feeding barrel and an inner feeding barrel. A rotating rod 7 is provided in the inner feeding barrel, and spiral blades are evenly installed on the rotating rod 7. A first motor 8 is installed on the outer side of the outer feeding barrel 5, and the rotating rod 7 is driven by the motor to rotate, thereby promoting uniform transportation and heating of the aluminum ingot. The feeding hopper 6 is located on the side close to the auxiliary material feeding port 2 to ensure that the auxiliary material can be fully mixed with the aluminum ingot during the heating process of the aluminum ingot, thereby improving the temperature control and processing performance of the aluminum ingot.

[0025] Furthermore, uniform transportation of the aluminum ingots during the heating process is ensured, and the mixing of the aluminum ingots is promoted by rotating the rotating rod 7, accelerating the reaction of the aluminum ingots with external auxiliary materials, effectively avoiding uneven heating or brittleness of the aluminum ingots, and improving the heating effect and processing performance of the aluminum alloy.

The roller 12 is in the shape of a cone or a truncated cone, and its radius increases as it approaches the profile die 4, thereby enhancing the extrusion effect and ensuring the accuracy and surface quality of the aluminum profile.

[0029] Furthermore, the aluminum ingot is uniformly stressed during the extrusion process, avoiding problems such as uneven pressure or incomplete extrusion. The special shape and increased radius design of the roller 12 help improve the extrusion efficiency and reduce the deformation and loss of the aluminum during the extrusion process, thereby ensuring the accuracy and performance of the extruded profile.

[0030] Embodiment 4: The outer extrusion tube 10 is respectively provided with a protective gas injection port 15 and a gas exhaust port 16 , and both the protective gas injection port 15 and the gas exhaust port 16 are connected to the inner extrusion tube 11 , and the protective gas injection port 15 is located on a side away from the profile mold 4 , and the gas exhaust port 16 is located on a side close to the profile mold 4 .
