Description

Technical Field

[0001] This utility model belongs to the technical field of parallel flow zinc-aluminum flat tube extrusion die, specifically a narrow-spacing four-hole type parallel flow zinc-aluminum flat tube extrusion die. Background Technology

[0002] The narrow-spacing four-hole parallel flow zinc-sprayed aluminum flat tube extrusion die is a die specifically designed for producing narrow-spacing four-hole parallel flow zinc-sprayed aluminum flat tubes. Through a specific structure and process, it can extrude aluminum billets within the die cavity to obtain aluminum flat tubes with the required cross-sectional shape, size, and mechanical properties.

[0003] Existing narrow-gap four-hole parallel-flow zinc-aluminum flat tube extrusion dies include a die frame, multiple die pillars, and two opposing extrusion plates. The die frame also contains a heating element, typically a heating wire. Aluminum material is transferred to the die frame via an external conveying device and heated and melted by the heating element. During this continuous transfer, the molten aluminum material is initially formed into a narrow-gap four-hole parallel-flow zinc-aluminum flat tube by the multiple die pillars. Subsequently, the two opposing extrusion plates extrude the complete narrow-gap four-hole parallel-flow zinc-aluminum flat tube. However, existing extrusion dies lack a positioning structure for the aluminum material. During the transfer of aluminum material into the die frame, it may shift due to vibration and friction, leading to dimensional deviations or shape distortions in the aluminum material during subsequent extrusion. Summary of the Invention

[0004] The purpose of this invention is to provide a narrow-spacing four-hole parallel flow zinc-aluminum flat tube extrusion die to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a narrow-spacing four-hole parallel flow jet zinc-aluminum flat tube extrusion die, including a die body and a transmission roller disposed on one side of the die body, wherein a positioning component is disposed on one side of the transmission roller of the die body;

[0006] The positioning assembly includes a positioning plate and a threaded rod. Two positioning plates are provided. A movable groove is provided on one side of the mold body. Both positioning plates are movably disposed in the movable groove. The side of each positioning plate away from the movable groove is in contact with the side of the transmission roller. The side of each positioning plate that is close to each other is set in an arc shape. One end of the threaded rod extends into the movable groove, and the end of the threaded rod close to the movable groove passes through both positioning plates.

[0007] Preferably, the mold body includes a fixing group and a mold frame, the transmission roller is disposed on one side of the mold frame, the fixing group is disposed inside the mold frame, and a discharge frame is disposed on the side of the mold frame away from the transmission roller.

[0008] Preferably, two partitions are fixedly connected to one side of the mold frame, and a connecting plate is fixedly connected to the bottom of the two partitions. The connecting plate and the side of the two partitions away from the mold frame are all in contact with one side of the transmission roller.

[0009] Preferably, the fixing assembly includes a first mold column, a second mold column, and an extrusion plate. Multiple first mold columns and multiple second mold columns are provided. Support plates are fixedly connected to opposite sides of the multiple first mold columns. Opposite sides of the multiple support plates are respectively fixedly connected to opposite inner walls of the mold frame. One end of each of the multiple second mold columns is fixedly connected to one end of each of the multiple first mold columns. Two extrusion plates are provided, and multiple second mold columns are positioned between the two extrusion plates. Opposite sides of the two extrusion plates are respectively fixedly connected to opposite inner walls of the mold frame. The sides of the two extrusion plates that are close to each other are both inclined.

[0010] Preferably, one end of the threaded rod is fixedly connected to a rotating disk.

[0011] Preferably, a heating element is provided inside the mold frame, and a heat-conducting plate is fixedly connected to the upper end of the heating element.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model is equipped with two positioning plates, and the side of the two positioning plates that are close to each other is set in an arc shape. When the aluminum material is transported, the aluminum material will come into contact with the arc-shaped side of the two positioning plates as it enters the interior of the mold body, and finally reach the position between the two positioning plates, thereby realizing the positioning and transport of the aluminum material and ensuring that the aluminum material always maintains the correct position. This ensures the extrusion quality of the subsequent aluminum material extrusion process. The distance between the two positioning plates can be controlled by rotating the threaded rod, so that aluminum materials of different specifications can be positioned and transported.

[0014] 2. A transfer roller is provided on one side of the mold body of this utility model. When the aluminum tube is transferred, the temperature rises due to friction between the rotating transfer roller and the mold body surface, thereby softening the aluminum material. As it is continuously pushed forward, the softened aluminum material enters the mold body and is further heated in the mold body, raising the aluminum material to a suitable temperature and making it semi-molten. It is then extruded to form an aluminum flat tube with the same shape as the mold exit end face. The rotation of the transfer roller causes the aluminum material to generate heat through friction. In continuous extrusion production, energy can be saved and the heating speed of the aluminum material can be accelerated. Attached Figure Description

[0026] Reference Figure 1-5 The present invention provides a narrow-spacing four-hole parallel flow spray zinc-aluminum flat tube extrusion die. The die includes a die body and a transfer roller 2 disposed on one side of the die body. A positioning component is disposed on one side of the transfer roller 2 on the die body.

[0027] The positioning assembly includes a positioning plate 6 and a threaded rod 9. There are two positioning plates 6. A movable groove is provided on one side of the mold body. Both positioning plates 6 are movably set in the movable groove. The side of the two positioning plates 6 away from the movable groove is in contact with the side of the transmission roller 2. The side of the two positioning plates 6 that are close to each other is set in an arc shape. One end of the threaded rod 9 extends into the movable groove, and the end of the threaded rod 9 that is close to the movable groove passes through the two positioning plates 6.

[0028] Specifically, by setting two positioning plates 6, with the sides of the two positioning plates 6 close to each other being arc-shaped, when the aluminum material enters the interior of the mold body, it will come into contact with the arc-shaped sides of the two positioning plates 6 during the transfer of the aluminum material, and finally reach the position between the two positioning plates 6, thereby realizing the positioning and transfer of the aluminum material, ensuring that the aluminum material always maintains the correct position, ensuring the extrusion quality of the subsequent extrusion process, and the distance between the two positioning plates 6 can be controlled by rotating the threaded rod 9, so that aluminum materials of different specifications can be positioned and transferred.

[0029] By setting a transfer roller 2 on one side of the mold body, the temperature rises due to friction between the rotating transfer roller 2 and the mold body surface during the transfer of aluminum tube, thereby softening the aluminum material. As it continues to move forward, the softened aluminum material enters the mold body and is further heated in the mold body, raising the temperature of the aluminum material to about 450℃~500℃ and reaching a semi-molten state. It is then extruded to form an aluminum flat tube with the same shape as the mold exit end face. The rotation of the transfer roller 2 causes the aluminum material to generate heat through friction. In continuous extrusion production, this can save energy and accelerate the heating speed of the aluminum material.

[0030] The aforementioned drive for the transmission roller 2 can be achieved by connecting an external motor, which in turn drives the transmission roller 2 to rotate.

[0031] The mold body includes a fixing group and a mold frame 1. The transmission roller 2 is set on one side of the mold frame 1, and the fixing group is set inside the mold frame 1. A discharge frame 3 is set on the side of the mold frame 1 away from the transmission roller 2. Two partitions 13 are fixedly connected to one side of the mold frame 1, and a connecting plate 14 is fixedly connected to the bottom of the two partitions 13. The connecting plate 14 and the two partitions 13 are both in contact with one side of the transmission roller 2 on the side away from the mold frame 1. By setting the two partitions 13 and the connecting plate 14, the aluminum material can be limited to prevent the aluminum material from moving to the mold frame 1 during the transmission process.

[0032] The fixed assembly includes a first mold column 7, a second mold column 8, and an extrusion plate 5. Multiple first mold columns 7 and multiple second mold columns 8 are provided. Support plates 10 are fixedly connected to the opposite sides of the multiple first mold columns 7. The opposite sides of the multiple support plates 10 are fixedly connected to the opposite inner walls of the mold frame 1. One end of the multiple second mold columns 8 is fixedly connected to one end of the multiple first mold columns. Two extrusion plates 5 are provided. Multiple second mold columns are provided between the two extrusion plates 5. The opposite sides of the two extrusion plates 5 are fixedly connected to the opposite inner walls of the mold frame 1. The sides of the two extrusion plates 5 that are close to each other are both set in an inclined shape. One end of the threaded rod 9 is fixedly connected to a rotating disk 4. A heating element 11 is provided inside the mold frame 1. A heat-conducting plate 12 is fixedly connected to the upper end of the heating element 11.

[0033] Specifically, the aluminum material is heated and melted by the heating element 11. During the continuous transmission process, the molten aluminum material is initially formed into a narrow-spacing four-hole parallel flow zinc-aluminum flat tube by multiple mold columns 7. Then, the complete narrow-spacing four-hole parallel flow zinc-aluminum flat tube is extruded by two oppositely arranged extrusion plates 5.

[0034] Working principle: This utility model sets two positioning plates 6, and the side of the two positioning plates 6 that is close to each other is set as arc shape. When the aluminum material is transported, the aluminum material will come into contact with the arc-shaped side of the two positioning plates 6 as it enters the mold frame 1, and finally reach the middle position of the two positioning plates 6, so as to realize the positioning and transport of the aluminum material, ensuring that the aluminum material always maintains the correct position, thereby ensuring the extrusion quality of the subsequent aluminum material extrusion process. The distance between the two positioning plates 6 can be controlled by rotating the threaded rod 9, so that aluminum materials of different specifications can be positioned and transported.

[0035] The aluminum material is heated and melted by the heating element 11. During the continuous transmission process, the molten aluminum material is initially formed into a narrow-spacing four-hole parallel flow zinc-aluminum flat tube by multiple mold columns 7. Then, the complete narrow-spacing four-hole parallel flow zinc-aluminum flat tube is extruded by two oppositely arranged extrusion plates 5.

[0036] By setting a transfer roller 2 on one side of the mold body, the temperature rises due to friction between the rotating transfer roller 2 and the mold body surface during the transfer of aluminum tubes, thereby softening the aluminum material. As the material continues to move forward, the softened aluminum material enters the mold body and is further heated, raising the temperature of the aluminum material to about 450℃~500℃, reaching a semi-molten state. It is then extruded to form an aluminum flat tube with the same shape as the mold exit end face. The rotation of the transfer roller 2 generates heat through friction of the aluminum material, which can save energy and accelerate the heating speed of the aluminum material in continuous extrusion production.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
