[0013] Compared with the prior art, the present utility model provides an aluminum chip extrusion forming device, which has the following

[0014] Beneficial effects:

[0015] 1. The aluminum chip extrusion forming device can achieve uniform mixing by setting up a crushing drive device and a stirring device. The stirring device can evenly distribute the aluminum chips in the fusion barrel, ensuring that every part of the aluminum chips can come into contact with the heating source, thus accelerating the melting speed. It can break large pieces. If there are large pieces of materials in the aluminum chips, the stirring device can break the aluminum chips into smaller particles through its blades, increasing the contact area between the materials and the heating source and accelerating melting. It can promote heat transfer. Through stirring, the gaps between the aluminum chips can be reduced, enabling heat to be more effectively transferred to the interior of the materials, thereby shortening the melting time. It can prevent material caking. At high temperatures, if the aluminum chips tend to cake, the stirring device can prevent this from happening and maintain the fluidity of the aluminum solution.

[0016] 2. The aluminum chip extrusion forming device is equipped with a feeding screw frame. When it rotates, its spiral structure can push the aluminum solution downward, which helps to increase the flow rate of the aluminum solution, enabling it to enter the next processing step through the discharging end more quickly, improving production efficiency, reducing the residence time of the materials during melting and transportation, and also helping to ensure the uniformity and continuity of the material flow.

[0017] 3. The aluminum chip extrusion forming device is provided with a first support frame, a second support frame and a scraper, which can effectively scrape off the aluminum solution or solid residues adhering to the inner wall of the metal fusion barrel, ensuring the cleanliness and smoothness of the discharging end; improving the discharging efficiency: reducing the blockage caused by the inner wall adhesions, enabling the aluminum solution to be discharged more smoothly; reducing material waste: the scraper can scrape off the materials adhering to the inner wall and make them return to the molten state for full utilization; extending the service life of the equipment: regular cleaning of the inner wall can prevent the accumulation of residues, reducing corrosion and wear of the equipment; ensuring product quality: a clean discharging end can reduce pollution caused by residues and ensure the purity of the aluminum solution.

A metal fusion barrel 10 is fixedly installed on the top of the mounting frame 8. A crushing driving device 11 is arranged on the top of the metal fusion barrel 10. The rotating end of the crushing driving device 11 is fixedly connected with a stirring device 14. The bottom of the stirring device 14 is fixedly connected with a feeding screw frame 15. A first support frame 16 is fixedly installed at a position near the top on the right side of the feeding screw frame 15. A second support frame 18 is fixedly installed at a position near the bottom on the right side of the feeding screw frame 15. One end of the second support frame 18 away from the feeding screw frame 15 is fixedly connected with a scraper 17. A feeding end 1 is arranged on the top of the metal fusion barrel 10. A discharging end 2 is arranged at the bottom of the metal fusion barrel 10. A heater 9 is arranged on the metal fusion barrel 10.

[0024] Specifically, one end of the first support frame 16 away from the feeding screw frame 15 is fixedly connected with the position near the top on the left side of the scraper 17. One end of the scraper 17 away from the first support frame 16 is close to the inner wall of the discharging end 2.

A high-temperature resistant sealing ring is arranged at the connection between the stirring device 14 and the stabilizing frame 13. Crushing blades are arranged on the outer surface of the stirring device 14. The top of the stirring device 14 penetrates through the inner top wall of the metal fusion barrel 10 and is fixedly connected with the rotating end of the crushing driving device 11.

[0028] Specifically, both ends of the stabilizer 13 are fixedly connected to the inner wall of the metal fusion barrel 10 near the bottom.

[0033] In summary, for the aluminum chip extrusion forming device, by setting up the crushing drive device 11 and the stirring device 14, the following functions can be achieved: Mixing evenly: The stirring device 14 can evenly distribute the aluminum chips in the fusion barrel, ensuring that every part of the aluminum chips can come into contact with the heating source, thereby accelerating the melting speed; Crushing large pieces: If there are larger pieces of materials in the aluminum chips, the stirring device 14 can break the aluminum chips into smaller particles through its blades, increasing the contact area between the materials and the heating source and accelerating melting; Promoting heat transfer: Through stirring, the gaps between the aluminum chips can be reduced, enabling heat to be more effectively transferred to the interior of the materials, thereby shortening the melting time; Preventing material caking: At high temperatures, if the aluminum chips cake, the stirring device 14 can prevent this from happening and maintain the fluidity of the aluminum solution; By setting up the feeding spiral frame 15, its spiral structure can push the aluminum solution downward when rotating.
