Description

Technical Field

[0001] This utility model belongs to the field of copper alloy microfiber technology, and in particular relates to a drawing die for preparing high-tensile copper alloy microfibers. Background Technology

[0002] Copper alloy ultrafine wire is an ultrafine metal wire with a diameter of less than 0.05 mm, made primarily of copper through alloying and special processes. It possesses high strength, high conductivity, and excellent corrosion resistance. Its production process combines directional solidification continuous casting technology with multi-pass drawing processes. Through steps such as vacuum drawing of oxygen-free copper rods, continuous extrusion, and intermediate annealing, grain refinement and microstructure homogenization are achieved, ultimately yielding ultrafine wires with a diameter of 0.01-0.05 mm. The length of a single wire can reach hundreds of thousands of meters. Typical products, such as Cu-Ag alloy wire, have a tensile strength of 1.3 GPa in the drawn state and a conductivity exceeding 90% IACS. It also has high elongation and fatigue resistance. The addition of rare earth elements can refine the grain and improve thermal stability, giving the material advantages in fields such as microelectronic packaging, 5G high-frequency transmission lines, and precision wires for robots. Currently, domestically produced ultrafine copper wire has gradually replaced imports, but high-end products with a diameter of less than 0.02 mm still face technical bottlenecks, requiring further optimization of alloy composition and drawing processes.

[0003] Copper alloy microfilaments are manufactured through a drawing process, which requires the use of a drawing die. By forcing the copper alloy wire through the die holes, the diameter of the wire can be reduced. During the drawing process, the copper alloy wire generates heat, causing its temperature to rise, necessitating cooling. However, currently used drawing dies lack heat dissipation capabilities. Therefore, it is necessary to provide a drawing die for manufacturing high-tensile copper alloy microfilaments to solve this problem. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model should fall within the protection scope of the present utility model.

[0023] Please refer to the following: Figure 1-5 A drawing die for preparing high-tensile copper alloy microfilaments includes a mounting platform 1, a die body 2 mounted on the top of the mounting platform 1, two sets of fixing rings 3 symmetrically mounted on the outer side of the die body 2, a die hole 4 inside the die body 2, an inlet pipe 5 connected to the top of the die hole 4, an outlet pipe 6 connected to the bottom of the die hole 4, two sets of support plates 7 symmetrically mounted on the bottom of the mounting platform 1, a base 8 mounted on the bottom of the support plates 7, a water tank 9 mounted on the top of the base 8, a filling pipe 10 mounted on the upper front of the water tank 9, a water pump 11 mounted on the bottom front of the water tank 9, the water pump 11 and the inlet pipe 5 connected by a water supply pipe 12, a pipe clamp 13 mounted in the middle of the front of the mounting platform 1, a drying pipe 14 mounted on the left side of the die body 2, and a connecting pipe 15 mounted on the top of the drying pipe 14.

[0024] The mold body 2 installed on the top of the mounting platform 1 is set as a cylindrical structure. The inner diameter of the fixing ring 3 installed on the mold body 2 is the same as the outer diameter of the mold body 2. The bottom of both sides of the fixing ring 3 is fixedly connected to the top of the mounting platform 1 by fixing bolts. Thus, the mold body 2 is fixedly installed in the middle of the top of the mounting platform 1 by two sets of fixing rings 3.

[0025] The inlet pipe 5 and the outlet pipe 6 are inserted into the through groove in the middle of the mold body 2. The outlet pipe 6 passes through the through hole in the middle of the mounting platform 1 and is inserted into the through hole in the middle of the top of the water tank 9, so that the outlet pipe 6 is connected to the water tank 9.

[0026] Fixing holes are provided at the four corners of the base 8, in which locking pins can be installed, so that the base 8 can be fixedly installed on the ground. The base 8 and the mounting platform 1 have the same specifications. The mounting platform 1 can be stably supported by two sets of support plates 7. By fixing the base 8, the device can be fixedly installed on the ground, so that the device has good stability when in use.

[0027] The filling pipe 10 installed on the front of the water tank 9 is connected to the inside of the water tank 9. Coolant can be added to the inside of the water tank 9 through the filling pipe 10. A pipe cap is installed on the front of the filling pipe 10 to close the filling pipe 10.

[0028] The water pump 11 is connected to the interior of the water tank 9. The top of the inlet pipe 5 extends out of the top of the mold body 2, and the top of the water supply pipe 12 is connected to the top of the inlet pipe 5. The water pump 11 and the water supply pipe 12 can guide the coolant inside the water tank 9 into the inlet pipe 5. Then, the coolant flows downward through the inlet pipe 5 into the mold hole 4 opened in the middle of the mold body 2, thereby cooling the copper alloy wire that passes through the mold hole 4 for wire drawing. The coolant in the mold hole 4 can flow back into the water tank 9 through the outlet pipe 6 at the bottom of the mold hole 4. The interior of the water tank 9 is equipped with a cooling component to cool the coolant inside the water tank 9. The cooled coolant is then... The coolant enters the die hole 4 through the water pump 11, water supply pipe 12 and liquid inlet pipe 5, thus forming a coolant reflux structure. This keeps the coolant in the die hole 4 at a low temperature, thereby meeting the cooling needs of the copper alloy during the copper alloy wire drawing process and improving the yield of the copper alloy. When it is necessary to remove the coolant from the inside of the water tank 9, the water supply pipe 12 and liquid inlet pipe 5 are separated. The waste liquid in the water tank 9 can then be discharged from the water supply pipe 12 by the water pump 11. Then, new coolant is added to the water tank 9 through the filling pipe 10. The middle part of the water supply pipe 12 is inserted into the internal groove of the pipe clamp 13, thereby limiting the water supply pipe 12 laterally and improving the stability of the water supply pipe 12.

[0029] The inner diameter of the drying tube 14 is larger than the size of the mold holes 4 on both sides of the mold body 2. The drying tube 14 is fixedly installed on the left side of the mold body 2. The left end of the drying tube 14 is set as a tapered structure and an open structure, so that the copper alloy ultrafine wire drawn into shape can pass through the drying tube 14. The connecting tube 15 installed at the top of the drying tube 14 is connected to the inside of the drying tube 14. The connecting tube 15 can be connected to an external fan, so that the copper alloy ultrafine wire passing through the drying tube 14 can be dried by blowing air, so that the coolant on the surface of the copper alloy ultrafine wire can be dried quickly.
