[0002] In the profile processing process, external aluminum rods need to be cut into aluminum ingots 101 of a preset length. The aluminum ingots 101 are pushed into a furnace chamber at a high temperature. The aluminum ingots 101 are extruded by a forming die into profiles 102 of a preset shape. The profiles 102 are transported to the next station by a conveying mechanism. Because the profiles 102 are at a high temperature after forming, the load-bearing components of the conveying mechanism need to be made of high-temperature resistant materials in order to complete the conveying and transfer of the profiles 102. This results in high production costs and cannot meet production requirements, so improvements are needed. Summary of the Invention

[0027] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0028] Please see Figures 1 to 4 The present invention provides an extrusion device for aluminum production, comprising a forming mechanism 1 and a conveying mechanism 2.

[0029] The forming mechanism 1 includes a furnace body 11, a movable plate 12, a pusher plate 13, and several connecting components 14. The furnace body 11 and the movable plate 12 form a furnace cavity. The movable plate 12 is provided with a forming hole 121, which communicates with the furnace cavity. The pusher plate 13 is provided with a through hole 131, and the central axis of the forming hole 121 and the central axis of the through hole 131 coincide.

[0030] Each set of connecting components 14 connects the push plate 13 and the movable plate 12, and a number of connecting components 14 are arranged in a ring array around the central axis of the forming hole 121;

[0031] The conveying mechanism 2 includes a rotating shaft 21 and a protrusion 22 disposed on the rotating shaft 21. The protrusion 22 is disposed on the side surface of the rotating shaft 21.

[0032] Specifically, in this embodiment, an aluminum ingot 101 of a predetermined length is pushed into the furnace cavity. The temperature inside the furnace cavity is controlled within a predetermined range. An external driving source applies external force to the push plate 13. The push plate 13 pushes the connecting component 14 and the movable plate 12 to move synchronously toward the furnace cavity, compressing the aluminum ingot 101 inside the furnace cavity. The aluminum ingot 101 is extruded and formed into a profile 102 through the forming hole 121 of the movable plate 12. The profile 102 enters the conveying mechanism 2 through the perforation 131. Preferably, the push plate 13 includes several connecting components 14. The central axis of the forming hole 121 of the several connecting components 14 is arranged in a ring array. This structure ensures that the pressure is applied evenly to the movable plate 12. At the same time, the arrangement of multiple connecting components 14 improves the heat dissipation effect between the push plate 13 and the movable plate 12, and quickly dissipates the surface heat of the profile 102.

[0033] The conveying mechanism 2 includes a rotating shaft 21 and a protrusion 22 disposed on the rotating shaft 21. The protrusion 22 is disposed on the side surface of the rotating shaft 21 and supports the profile 102. That is, there is a gap between the profile 102 and the rotating shaft 21, which has a rapid heat dissipation effect and avoids heat being directly transferred to the rotating shaft 21. This makes the surface temperature of the rotating shaft 21 in the working state lower than the temperature of the protrusion 22. Preferably, the protrusion 22 is made of a high-temperature resistant component, which reduces the wear and tear on the rotating shaft 21 and extends the service life of the rotating shaft 21.

[0034] By setting multiple connecting components 14 between the movable plate 12 and the push plate 13, the connecting components 14 are arranged in a ring array around the central axis of the forming hole 121. The multiple connecting components 14 connect the movable plate 12 and the push plate 13, so as to achieve the purpose of the push plate 13 driving the movable plate 12 to extrude and form the aluminum ingot 101 inside the furnace cavity. At the same time, the structure of the spacing between two adjacent connecting components 14 accelerates the heat dissipation of the surface of the profile 102 after forming, thus meeting the production requirements.

[0035] Each set of connecting components 14 includes a central rod 141 and several side rods 142. The two ends of the side rods 142 are connected to the movable plate 12 and the push plate 13, respectively. The two ends of the central rod 141 are connected to the movable plate 12 and the push plate 13, respectively. The side rods 142 are arranged in a ring array around the central axis of the central rod 141. Each set has one central rod 141. Multiple sets of connecting components 14 have multiple central rods 141. The multiple central rods 141 have the purpose of being at the same height, that is, to ensure that the movable plate 12 and the push plate 13 are parallel structures, to ensure the balance of pressure per unit area of ​​the movable plate 12, and to ensure the firmness of the connection between the movable plate 12 and the push plate 13.

[0036] The central axis of the side rod 142 is set at an angle to the central axis of the central rod 141. By setting the inclined side rod 142, the force-bearing area of ​​the movable plate 12 is expanded, and the overall force-bearing area of ​​the movable plate 12 is increased, that is, the extrusion balance force on the aluminum ingot 101 in the furnace cavity is increased.

[0037] Each of the connecting components 14 further includes a first reinforcing plate 143, which is disposed on the push plate 13. The central rod 141 passes through the first reinforcing plate 143 and is connected to the push plate 13. The side rod 142 passes through the first reinforcing plate 143 and is connected to the push plate 13. The first reinforcing plate 143 further improves the firmness of the connection between the central rod 141 and the push plate 13, and at the same time has the purpose of limiting the center rod 141 and the side rod 142, ensuring the firmness of the connection between the movable plate 12 and the push plate 13.

[0038] Each set of connecting components 14 further includes a second reinforcing plate 144, which is disposed on the movable plate 12. The central rod 141 passes through the second reinforcing plate 144 and is connected to the movable plate 12. The side rod 142 passes through the second reinforcing plate 144 and is connected to the movable plate 12. The provision of the second reinforcing plate 144 further improves the firmness of the connection between the central rod 141 and the movable plate 12, and at the same time has the purpose of limiting the center rod 141 and the side rod 142, thus ensuring the firmness of the connection between the movable plate 12 and the movable plate 12.

[0039] The conveying mechanism 2 also includes a cooling element 23, which is located between two adjacent protrusions 22. An external cooling medium is introduced into the cooling element 23. The cooling medium is a flowing liquid that quickly dissipates heat.

[0040] The protrusion 22 is spiral-shaped, and the cooling component 23 is spiral-shaped. The spiral protrusion 22 is provided to ensure the stability of the contact surface between the protrusion 22 and the profile 102 during the rotation of the shaft 21, thereby improving production safety.

[0041] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
