[0041] In order to further understand the features, technical means and specific purposes and functions achieved by the present application, the present application will be described in further detail below in conjunction with the drawings and specific embodiments.

[0042] As Figures 1-10 shown:

[0043] The application discloses an aluminum material extrusion forming device and a forming process. The extrusion forming process is executed by the aluminum material extrusion forming device. The aluminum material extrusion forming device comprises a base 1, an extrusion assembly 2, a discharge box 3, a heating assembly 5, a die changing assembly, a die 6a and a feeding assembly 4. The extrusion assembly 2 and the discharge box 3 are located at two ends of the base 1 in the length direction. The heating assembly 5 and the feeding assembly 4 are both located on the side of the base 1. The discharge box 3 has a cuboid structure. A channel 3a penetrating through the side wall of the discharge box 3 in the width direction is formed on the side wall. The die changing assembly is located in the channel 3a. The die 6a is located on the die changing assembly. A feeding port 3b and a discharge port 3c penetrating through the side wall of the discharge box 3 in the length direction are formed on the side wall. A ingot containing cylinder 3d movably connected with the feeding port 3b is arranged in the feeding port 3b. A temperature control assembly 3e is arranged in the discharge box 3. The forming process comprises the following steps: the feeding assembly 4 delivers aluminum ingots to the heating assembly 5; the heating assembly 5 heats the aluminum ingots; the feeding assembly 4 delivers the heated aluminum ingots to the base 1; the die changing assembly moves the die 6a to the channel 3a of the discharge box 3 and abuts against the ingot containing cylinder 3d; the extrusion assembly 2 pushes the aluminum ingots on the feeding assembly 4 into the ingot containing cylinder 3d and extrudes the aluminum ingots until the aluminum ingots are discharged from the discharge port 3c through the ingot containing cylinder 3d and the die 6a in sequence, and the formed aluminum material is obtained; in the extrusion process, the temperature control assembly 3e of the discharge box 3 adjusts the temperature of the ingot containing cylinder 3d, the die 6a and the aluminum ingots.

[0044] Based on the above embodiment, first, the feeding assembly 4 delivers aluminum ingots to the heating assembly 5; then the heating assembly 5 heats the aluminum ingots; the heated aluminum ingots are delivered to the base 1 by the feeding assembly 4; at the same time, the die changing assembly moves the die 6a to the channel 3a of the discharge box 3 and abuts against the ingot containing cylinder 3d; the extrusion assembly 2 pushes the aluminum ingots into the ingot containing cylinder 3d and extrudes the aluminum ingots until the aluminum ingots are discharged from the discharge port 3c through the ingot containing cylinder 3d and the die 6a in sequence, and the formed aluminum material is obtained; when the die 6a abuts against the ingot containing cylinder 3d, the die 6a needs to be heated. However, in the prior art, in order to ensure the temperature of the die 6a, the extrusion of the aluminum material must be performed in a short time. If the temperature of the die 6a is too high, thermal stress and thermal fatigue in the extrusion process will be caused, the surface quality of the extruded profile will be affected, the temperature is too low, the cooling speed of the die 6a in the extrusion process will be too fast, the deformation resistance and the load of the die 6a will be increased, and the service life of the die 6a will be shortened. Through the arrangement of the die changing assembly, the die 6a placed on the die changing assembly can be quickly abutted against the ingot containing cylinder 3d in the discharge box 3. Meanwhile, a plurality of dies 6a can be arranged, the installation and replacement time of the dies 6a is reduced, the temperature of the die 6a in the discharge box 3 can be controlled by the temperature control assembly 3e in the discharge box 3, and the temperature of the die 6a can be maintained at a certain temperature, thereby improving the production efficiency and the product quality.

[0045] Further, the ingot cylinder 3d also needs to be heated before the extrusion process. If the ingot cylinder 3d is not uniformly heated, a large thermal stress will be generated. When the thermal stress exceeds the maximum stress that the ingot cylinder 3d can withstand, the ingot cylinder 3d will be broken. In order to solve the technical problem of uniform heating of the ingot cylinder 3d, as shown in Figure 4

[0046] The ingot cylinder 3d is provided with a plurality of mounting holes 3d1 around the center line thereof. A plurality of first electric heating pipes 3d2 are arranged in all the mounting holes 3d1, and the plurality of first electric heating pipes 3d2 are electrically connected.

[0047] Based on the above embodiment, the ingot cylinder 3d provided by the present application is heated by the first electric heating pipe 3d2. The heating of the ingot cylinder 3d is more uniform due to the arrangement around the center line of the ingot cylinder 3d. In order to further facilitate the adjustment of the temperature of the ingot cylinder 3d, the temperature can be controlled along the center line of the ingot cylinder 3d by the arrangement of the plurality of first electric heating pipes 3d2, so that the temperature of the ingot cylinder 3d is more uniform. Since the first electric heating pipe 3d2 is a consumable, the installation of the mounting hole 3d1 facilitates the replacement of the first electric heating pipe 3d2, thereby solving the above problems.

[0048] Further, in order to solve the technical problem of better controlling the temperature rise of the ingot cylinder 3d and the mold 6a during the extrusion process,

[0049] The discharge box 3 is further provided with a temperature sensor.

[0050] Based on the above embodiment, the discharge box 3 provided by the present application is provided with a temperature sensor, which facilitates real-time monitoring of the temperature at each stage of the extrusion process, and facilitates the temperature control of the ingot cylinder 3d and the mold 6a in the discharge box 3, thereby solving the above problems.

[0051] Further, the ingot cylinder 3d provided by the present application still has aluminum ingots remaining after extrusion. If the aluminum ingots are not demolded, it may cause uneven thickness of the formed aluminum material. In order to solve this problem, as shown in Figures 3-6

[0052] ​​The upper part of the discharge box 3 is also provided with a shearing assembly 7, the shearing assembly 7 comprises a sliding seat 7a, a first air cylinder 7a3, a cutter 7a2, a sliding plate 7a1, a mounting seat 7b1, a sliding rail 7b and two second air cylinders 7b2, the sliding seat 7a is located at one end of the top of the feeding port 3b of the discharge box 3, the sliding plate 7a1 is slidably installed in the sliding seat 7a, the cutter 7a2 is located at the bottom of the sliding plate 7a1, the first air cylinder 7a3 is located at the top of the sliding seat 7a, the output shaft of the first air cylinder 7a3 penetrates through the top of the sliding seat 7a and is fixedly connected with the sliding plate 7a1, the sliding rail 7b is horizontally located on the base 1 and between the discharge box 3 and the extruding assembly 2, the mounting seat 7b1 is slidably installed on the sliding rail 7b, the ingot containing cylinder 3d is fixedly connected with the mounting seat 7b1, and the two second air cylinders 7b2 are located at the bottom of the two sides of the discharge box 3 and close to one side of the mounting seat 7b1. The output shafts of the two second air cylinders 7b2 are fixedly connected with the two ends of the mounting seat 7b1.

[0053] Based on the above embodiment, the extruding assembly 2 provided by the application is used for extruding the aluminum ingot, and the feeding port 3b of the discharge box 3 still has residual aluminum ingot. If the residual aluminum ingot is not cut, it will cause the thickness of the aluminum material to be uneven when the aluminum ingot is extruded next time. Therefore, after the press is completed each time, the output shafts of the two second air cylinders 7b2 are simultaneously extended, so that the mounting seat 7b1 moves along the direction of the sliding rail 7b, thereby driving the ingot containing cylinder 3d on the mounting seat 7b1 to move away from the discharge port 3c. At this time, the first air cylinder 7a3 is started, the output shaft of the first air cylinder 7a3 is extended to drive the sliding plate 7a1 to move, so that the sliding plate 7a1 moves along the direction of the sliding seat 7a, thereby driving the cutter 7a2 at the bottom of the sliding plate 7a1 to move, so that the cutter 7a2 cuts the residual aluminum ingot, thereby ensuring the quality of the product and solving the above problem.

[0054] Further, in order to solve the technical problem of inspecting the formed aluminum material, as shown in Figure 3 、 Figure 5 and Figure 6 ,

The surface of the aluminum material after discharge is observed by the detection camera 3f. If the aluminum material is black, the speed of the extruding assembly 2 needs to be adjusted, and at the same time, the internal temperature of the discharge box 3 needs to be cooled to prevent the temperature of the aluminum material from being too high and affecting the quality of the product, thereby solving the above problem.

[0057] Further, since the mold 6a and the ingot cylinder 3d need to be preheated before extrusion, in order to solve the technical problem of temperature control of the discharge box 3 on the ingot cylinder 3d and the mold 6a, as shown in Figure 3 、 Figure 5 and Figure 6 : the temperature control assembly 3e includes a plurality of second electric heating pipes around the center line arranged on the feeding port 3b and the discharging port 3c, the heat dissipation fins 3e2 located inside the discharge box 3, and the heat dissipation air outlets 3e3 on both sides of the discharge box 3.

[0058] Based on the above embodiment, the discharge box 3 provided by the present application can heat and preserve the ingot cylinder 3d and the mold 6a through the second heating pipe 3e1. By heating and preserving the ingot cylinder 3d, the generation of thermal stress is reduced, and the heating of the ingot cylinder 3d is more uniform. By heating and preserving the mold 6a, the problem of re-melting and re-heating of the mold 6a is reduced, the thermal stress and thermal fatigue of the mold 6a are reduced, the deformation resistance and load of the mold 6a are reduced, and the service life of the mold 6a is prolonged. When the temperature of the ingot cylinder 3d and the mold 6a is too high during the extrusion process, the second electric heating pipe is closed, the ingot cylinder 3d and the mold 6a are cooled through the heat dissipation fins 3e2 inside the discharge box 3, and the excess heat is discharged through the heat dissipation air outlets 3e3, thereby solving the above problems.

[0059] Further, the extrusion device provided by the present application still has the defect that too many impurities are generated in the aluminum ingot during processing. In order to solve this problem, as shown in Figure 8 ,

[0062] Further, the ingot cylinder 3d provided by the present application still has the defect that it is not convenient to demold the aluminum ingot. In order to solve this problem, as shown in Figure 10 ,
