[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 The technical solution provided by this utility model is as follows:

[0025] Example 1:

[0026] A metal wire drawing device includes a processing box 1 and an integral partition connected to the middle of the processing box 1. The processing box 1 has through holes 2 at equal intervals on both sides and the middle partition. A cylindrical die head 3 is rotatably connected to one side of the partition, and the other side of the partition forms a wire drawing powder storage groove 8 with the processing box 1. The cylindrical die head 3 has drawing holes 9 through openings on its exterior, corresponding to the through holes 2. There are at least five sets of drawing holes 9 evenly distributed on the cylindrical die head 3. Each set of drawing holes 9 consists of five drawing holes 9 of different sizes. The five drawing holes 9 are distributed in a ring at equal intervals on the cylindrical die head 3.

[0027] Limiting fasteners are provided between the front and rear ends of the cylindrical mold head 3 and the processing box 1;

[0028] The limiting and fixing component includes a connecting groove 12 that is circumferentially and equidistantly opened on the cylindrical die head 3. The connecting groove 12 is located between adjacent drawing holes 9. A connecting block 7 is inserted into the connecting groove 12. A limiting groove 13 is opened on the inner wall of the processing box 1 at a position corresponding to the connecting groove 12. The top of the connecting block 7 is located in the limiting groove 13.

[0029] A mounting plate 4 is bolted to the outer wall of the processing box 1 at the corresponding position of the cylindrical mold head 3. The mounting plate 4 and the interior of the processing box 1 are respectively provided with mounting grooves 5. The two ends of the cylindrical mold head 3 are distributed in the mounting grooves 5. The mounting plate 4 is connected to the processing box 1 by bolts, which makes it convenient for the user to disassemble the mounting plate 4 to install and use the internal slide rail 10 and the two ends of the cylindrical mold head 3.

[0030] The mounting groove 5 is fixed with a circular slide rail 10, and the cylindrical mold head 3 is movably connected to the mounting groove 5 through the slide rail 10.

[0031] A cooling groove 11 is provided through the interior of the cylindrical die head 3, and the two ends of the cooling groove 11 extend to the two ends of the cylindrical die head 3. The cooling groove 11 is located between two adjacent drawing holes 9.

[0032] An axial fan 6 is connected to the mounting slot 5 by screws, and the axial fan 6 is located on one side of the cylindrical mold head 3.

[0033] By adopting the above technical solution, the metal wire to be processed is passed through the through hole 2 on the processing box 1 and the partition, and the metal wire passes through the drawing hole 9 on the surface of the cylindrical die head 3. One end of the metal wire is connected to the drawing machine built on one side of the processing box 1 after passing through the through hole 2, and is used for drawing the metal wire.

[0034] During operation, according to the processing requirements of metal wires of different sizes, the cylindrical die head 3 is rotated so that the drawing hole 9 of the corresponding size on the surface of the cylindrical die head 3 corresponds to the through hole 2 on the partition plate, and then the metal wire is drawn by the drawing machine.

[0035] During the rotation of the cylindrical mold head 3, both ends of the cylindrical mold head 3 rotate inside the mounting groove 5 via the slide rail 10. After rotating to a specified angle, that is, after the required size of the pull hole 9 on the surface of the cylindrical mold head 3 described above corresponds to the through hole 2 of the partition plate, the user can take the connecting block 7 and insert it into the limiting groove 13 on the inner wall of the processing box 1, and insert it into the connecting groove 12 on the surface of the cylindrical mold head 3, thereby cooperating with the processing box 1 to limit the rotation angle of the cylindrical mold head 3.

[0036] In the subsequent process, the cylindrical die head 3 generates high temperature by rubbing the metal wire through the drawing hole 9. By connecting the axial flow fan 6 to the external power supply for conductive operation, one set of the axial flow fans 6 in the two mounting slots 5 draws in the outside air and the other set discharges the air. In this way, the outside air passes through the cooling tank 11 and carries away the heat generated inside the cylindrical die head 3 for cooling and heat dissipation.

[0037] Example 2:

[0038] This application also provides another method for limiting and fixing the cylindrical mold head 3 and a cooling method for the cylindrical mold head 3. This method is different from the air cooling method used in Embodiment 1. This method uses water cooling. Limiting grooves 13 are opened at equal intervals in the ring on the inner wall of the mounting groove 5. Limiting grooves 13 are opened at the two ends of the cylindrical mold head 3 at the corresponding positions of limiting grooves 13. A disc 16 with an internal hollow structure is screwed into the mounting groove 5.

[0039] Limiting block 17 is fixed at the position corresponding to the first limit groove 13 on the outside of the disc 16. Limiting block 2 18 is fixed at equal distances in a ring on the side of the disc 16 near the cylindrical mold head 3. Limiting block 17 and limiting block 2 18 are located inside the first limit groove 13 and the second limit groove 13, respectively.

[0040] A sealing gasket 20 is fixed on one side of the disc 16 near the cylindrical mold head 3, and a water outlet 21 corresponding to the opening of the cooling tank 11 is opened on the side of the disc 16, and the water outlet 21 extends to the sealing gasket 20. A water inlet 19 is opened on the other side of the disc 16.

[0041] By adopting the above technical solution, this application uses a disc 16 bolted into the mounting groove 5. The limiting block 17 on the outside of the disc 16 corresponds to the limiting groove 13 on the inner wall of the mounting groove 5. The limiting block 18 is further inserted and fixed to the limiting groove 13 on one end of the cylindrical mold head 3. This method is used to limit the angle of the cylindrical mold head 3 after rotation. After the disc 16 is installed, one of the disc 16 water inlet holes 19 is connected to an external water pump pipe. The water pump continuously pumps cooling water into the disc 16 and discharges it into the cooling tank 11 through the water outlet hole 21 on the outside of the disc 16. Then it flows into another disc 16 in the mounting groove 5 and discharges cooling water through the water inlet hole 19 of the other disc 16. The cooling water flows through the cooling tank 11 and drives the heat generated inside the cylindrical mold head 3 to cool and dissipate heat.

[0042] Working principle:

[0043] During operation, the metal wire to be processed is threaded through the threading hole 2 on the processing box 1 and the partition, and the metal wire passes through the drawing hole 9 on the surface of the cylindrical die head 3. One end of the metal wire passes through the threading hole 2 and is connected to the drawing machine built on one side of the processing box 1 for drawing the metal wire.

[0044] During operation, according to the processing requirements of metal wires of different sizes, the cylindrical die head 3 is rotated so that the drawing hole 9 of the corresponding size on the surface of the cylindrical die head 3 corresponds to the through hole 2 on the partition plate, and then the metal wire is drawn by the drawing machine.

[0045] During the rotation of the cylindrical mold head 3, both ends of the cylindrical mold head 3 rotate inside the mounting groove 5 via the slide rail 10. After rotating to a specified angle, that is, after the required size of the pull hole 9 on the surface of the cylindrical mold head 3 described above corresponds to the through hole 2 of the partition plate, the user can take the connecting block 7 and insert it into the limiting groove 13 on the inner wall of the processing box 1, and insert it into the connecting groove 12 on the surface of the cylindrical mold head 3, thereby cooperating with the processing box 1 to limit the rotation angle of the cylindrical mold head 3.

[0046] In the subsequent process, the cylindrical die head 3 generates high temperature by rubbing the metal wire through the drawing hole 9. By connecting the axial flow fan 6 to the external power supply for conductive operation, one set of the axial flow fans 6 in the two mounting slots 5 draws in the outside air and the other set discharges the air. In this way, the outside air passes through the cooling tank 11 and carries away the heat generated inside the cylindrical die head 3 for cooling and heat dissipation.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
