Description

Technical Field

[0001] This utility model relates to the field of enameled wire, and more specifically, to a wire drawing mechanism for copper-clad aluminum enameled wire. Background Technology

[0002] Enamelled wire refers to a metal conductor with an insulating varnish coating used for winding electromagnetic coils; it is also called electromagnetic wire. It is a major type of winding wire, consisting of a conductor and an insulation layer. The bare wire is annealed and softened, then coated with varnish multiple times and baked. In existing enamelled wire drawing devices, during the extrusion and drawing process, the die typically applies lateral extrusion to the enamelled wire as it moves continuously. This single lateral extrusion force easily leads to unstable extrusion pressure and uneven stress on the enamelled wire, resulting in surface deviations after the wire is formed.

[0003] Application CN116408359A discloses an enameled wire drawing device, relating to the field of enameled wire processing. It includes a frame with a detachable worktable connected to the top. A rotatable auxiliary forming component is mounted on the worktable for extruding and forming the enameled wire. Matching connecting pipes are provided on both sides of the auxiliary forming component. The enameled wire flows through the connecting pipes and the auxiliary forming component. A positioning arm is fixed to the outside of the connecting pipes, and a limit bracket is detachably mounted on the positioning arm, which is installed on the surface of the worktable. This invention, by providing a rotatable auxiliary forming component, provides a certain degree of buffering against the longitudinal rotational pressure generated by the rotation of the rotating arm and forming tube, as well as the lateral extrusion forming force experienced by the enameled wire during movement. As the enameled wire moves, the rotating arm and forming tube ensure that the enameled wire is evenly stressed, accelerating the forming process.

[0004] In the above-disclosed structure, the wire drawing operation is carried out by mounting multiple structures with brackets. However, it lacks a box-mounted connecting pipe and a cooling pipe, which cannot assist in cooling the drawn enameled wire and is not conducive to lubrication and protection. Furthermore, it lacks a rotating wire drawing die, which cannot rotate radially to ensure balance, affecting the surface quality of the enameled wire. It has poor adaptability and needs to be improved. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a wire drawing mechanism for copper-clad aluminum enameled wire. The mechanism uses a partition inside the housing to install connecting pipes and cooling pipes, which can store lubricating oil for cooling and lubrication, thus improving safety. Furthermore, the wire drawing molds are installed at both ends of the cooling pipes, and an intermediate gear is installed on the rotating shaft. This allows for synchronous driving and adjustment of the two ends, improving the uniformity of wire drawing, ensuring surface quality, facilitating combined use, and exhibiting high adaptability.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A wire drawing mechanism for copper-clad aluminum enameled wire includes a housing. A partition is fixedly connected to the center of the housing. Return holes are provided at both ends of the partition. Connecting pipes are fixedly connected to both ends of the partition. A cooling pipe is fixedly installed at the upper end of each connecting pipe. A wire drawing die is rotatably mounted at both ends of the cooling pipe. A driven gear is fixedly connected to one end of each wire drawing die. The driven gear is rotatably connected to both ends of the cooling pipe. Mounting brackets are fixedly connected to both ends of the upper surface of the cooling pipe. A rotating shaft is rotatably mounted at one end of each mounting bracket. Intermediate gears are rotatably mounted at both ends of the rotating shaft, meshing with one side of the driven gear. A motor is fixedly mounted at one end of each mounting bracket.

[0008] Furthermore, a pump head is fixedly installed at one end of the connecting pipe, and the pump head is fixedly installed on the lower surface of the partition.

[0009] Furthermore, there are two of each of the wire drawing die and driven gear, which are symmetrically connected to the two ends of the cooling pipe.

[0010] Furthermore, the rotating shaft is rotatably mounted on the upper end of the cooling pipe, and a pump head is installed through the connecting pipe to draw lubricating oil for cooling and lubrication. The two ends are fitted with wire drawing dies, which can perform two wire drawing operations, improving safety and stability and facilitating combined use.

[0011] Furthermore, a fixing bracket is fixedly connected to one side of the connecting pipe, and an inclined protective plate is fixedly connected to one end of the fixing bracket.

[0012] Furthermore, a support frame is fixedly connected to one side of the inclined protective plate, and a guide wheel is rotatably mounted on one side of the support frame.

[0013] Furthermore, the guide wheels are located at the exit position of the wire drawing die, and the inclined protective plate is located on the outside of the wire drawing die. The inclined protective plate is installed by a fixing frame, and the guide wheels are installed in conjunction with the support frame. This can protect the exit position, prevent lubricating oil from splashing, and guide the enameled wire out of the die, avoiding interference and ensuring stability.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) This solution uses a partition inside the box to install connecting pipes and cooling pipes, which can store lubricating oil for cooling and lubrication, which is beneficial for safety protection. Furthermore, the wire drawing mold is installed by rotating at both ends of the cooling pipe, and the intermediate gear is installed on the rotating shaft. The two ends can be driven synchronously for rotation adjustment, which improves the uniformity of wire drawing, ensures surface quality, is easy to use in combination, and has high adaptability.

[0016] (2) The pump head is installed through the connecting pipe, which can draw lubricating oil for cooling and lubrication. The wire drawing molds are installed at both ends of the machine, which can perform two wire drawing operations, improve safety and stability, and facilitate combination use.

[0017] (3) By installing the inclined protective plate through the fixed frame and the guide wheel through the support frame, the outlet position can be protected to avoid splashing of lubricating oil, and the enameled wire can be guided out to avoid interference and facilitate stability.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 , Figure 3 and Figure 4 A wire drawing mechanism for copper-clad aluminum enameled wire includes a housing 1. A partition 11 is fixedly connected to the center of the housing 1. Return holes 12 are provided at both ends of the partition 11. Connecting pipes 13 are fixedly connected to both ends of the partition 11. A cooling pipe 14 is fixedly installed at the upper end of the connecting pipe 13. Lubricating oil can be introduced through one side of the connecting pipe 13 and enters the cooling pipe 14. The enameled wire passing through this cooling pipe can be immersed in the interior, which can cool it down, preventing heat accumulation during wire drawing from affecting its toughness. It also lubricates the surface, improving safety and facilitating combined use. Return flow occurs through the other end of the connecting pipe 13, which is convenient, efficient, and facilitates recycling. Wire drawing dies 15 are rotatably installed at both ends of the cooling pipe 14, allowing the enameled wire to pass through and be compressed during rapid transport. The wire drawing die 15 is designed for easy assembly and use. One end of the wire drawing die 15 is fixedly connected to a driven gear 16. The driven gear 16 is connected to the two ends of the cooling pipe 14. The upper surface of the cooling pipe 14 is fixedly connected to two ends of the mounting bracket 17. One end of the mounting bracket 17 is rotatably mounted with a rotating shaft 18. Both ends of the rotating shaft 18 are rotatably mounted with intermediate gears 19. The intermediate gears 19 mesh with one side of the driven gear 16. One end of the mounting bracket 17 is fixedly mounted with a motor 2. One end of the motor 2 is rotatably mounted with a drive gear 21. The drive gear 21 meshes with one side of the intermediate gear 19. The motor 2 drives the drive gear 21 to rotate, which in turn meshes with the intermediate gear 19, thus driving the driven gear 16 to rotate, thereby driving the wire drawing die 15 to rotate. This ensures the uniformity of the wire drawing, guarantees surface quality, and facilitates easy assembly and use.

[0027] Please see Figure 2 and Figure 3 A pump head 22 is fixedly installed at one end of the connecting pipe 13. The pump head 22 is fixedly installed on the lower surface of the partition plate 11. There are two wire drawing dies 15 and two driven gears 16, which are symmetrically connected to the two ends of the cooling pipe 14. The rotating shaft 18 is rotatably installed at the upper end of the cooling pipe 14. The pump head is installed through the connecting pipe, which can draw lubricating oil for cooling and lubrication. The wire drawing dies are installed at both ends, which can perform two wire drawing operations, improve safety and stability, and facilitate combination use.

[0028] Please see Figure 3 and Figure 5A fixed bracket 23 is fixedly connected to one side of the connecting pipe 13. An inclined protective plate 24 is fixedly connected to one end of the fixed bracket 23. A support bracket 25 is fixedly connected to one side of the inclined protective plate 24. A guide wheel 26 is rotatably installed on one side of the support bracket 25. The guide wheel 26 is located at the outlet position of the wire drawing die 15. The inclined protective plate 24 is located on the outside of the wire drawing die 15. By installing the inclined protective plate through the fixed bracket and the guide wheel installed through the support bracket, the outlet position can be protected to prevent lubricating oil from splashing. It can also guide the enameled wire out of the box to avoid interference and facilitate stability. The lubricating oil enters the cooling pipe 14. Most of it flows back to the box 1 from the connecting pipe 13, and part of it enters the wire drawing die 15 and can flow out from the outlet position. Combined with the obstruction of the inclined protective plate 24 on the side to prevent splashing, it can flow back to the top of the partition 11 and then passively flow back from the return hole 12 to ensure safety and stability, improve the recycling effect, and have high adaptability.

[0029] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
