Technical Field

[0001] This utility model relates to the field of diamond wire drawing die technology, and more specifically to a diamond wire drawing die with a cooling structure. Background Technology

[0002] Wire drawing dies are key tools in metal pressure processing. They force metal through the die by external force, compressing its cross-sectional area and forming wires or bars of the required shape and size. They are the core consumable parts in metal wire production.

[0003] As the core component of the wire drawing die, the die core generates a lot of heat when the diamond wire drawing die is working. Excessive temperature will degrade the performance of the die material and accelerate the wear of the die. Usually, the die core will be damaged or worn before other components. If the entire wire drawing die is not removable and the die core cannot be replaced, then once the die core is damaged or worn severely, the entire wire drawing die will need to be scrapped and replaced, which will increase production costs.

[0015] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The diamond wire drawing die with a cooling structure involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Reference Figure 1-3 This utility model provides a diamond wire drawing die with a cooling structure, including a wire drawing component 1, an outer component 2 is provided on the outside of the wire drawing component 1, a water cooling component 3 is provided on the surface and inside of the outer component 2, an installation component 4 is provided on the inner wall of the outer component 2, and a fixing component 5 is provided on the right side of the wire drawing component 1 inside the outer component 2. The wire drawing assembly 1 includes a die core 101, a wire exit port 102, a wire inlet port 103, and a mounting block 104. The wire exit port 102 is located on the inner left side of the die core 101, and the left side of the wire exit port 102 has a smooth slope. The wire inlet port 103 is located on the inner right side of the die core 101. The mounting block 104 is symmetrically arranged on the outer left side of the die core 101, which facilitates the smooth entry of the metal wire into the wire exit port 102 through the wire inlet port 103 and reduces the friction between the wire and the die core 101.

[0017] The external component 2 includes a mold sleeve 201, a first heat dissipation groove 202, a second heat dissipation groove 203, a lubrication hole 204, and a fixing groove 205. The mold sleeve 201 is disposed outside the mold core 101. The first heat dissipation groove 202 is formed in a ring shape inside the mold sleeve 201. The second heat dissipation groove 203 is formed in a fan shape on the left side of the mold sleeve 201. The lubrication hole 204 is symmetrically formed on both sides of the inside of the mold core 101 and the mold sleeve 201. The fixing groove 205 is formed on the inner right side of the mold sleeve 201. This facilitates the dissipation of heat from the mold core 101 through the first heat dissipation groove 202 and the second heat dissipation groove 203, thereby reducing the temperature during wire drawing.

[0018] The water-cooling assembly 3 has a water-cooling tank 301, a water inlet 302, and a water outlet 303. The water-cooling tank 301 is annularly formed inside the mold sleeve 201 between the first heat dissipation tank 202 and the second heat dissipation tank 203. The water inlet 302 is formed at the top of the mold sleeve 201 and communicates with the inside of the water-cooling tank 301. The top opening diameter of the water inlet 302 is larger than the bottom opening diameter. The water outlet 303 is formed at the bottom of the mold sleeve 201 and communicates with the inside of the water-cooling tank 301. The bottom opening diameter of the water inlet 302 is larger than the opening diameter of the water outlet 303. This helps to ensure that the outflow velocity of the cooling water is greater than the inflow velocity, and ensures that the flow rate can meet the heat dissipation requirements.

[0019] The mounting component 4 has an inlet groove 401, a rotating groove 402, and a mounting groove 403. The inlet groove 401 is symmetrically located on both sides of the inner wall of the mold sleeve 201. The rotating groove 402 is located in the inner wall of the mold sleeve 201 and is connected to the inlet grooves 401 on both sides. The mounting groove 403 is symmetrically located on the left side of the inner wall of the mold sleeve 201 and is connected to the rotating groove 402. This facilitates the inlet of the mounting blocks 104 on both sides through the inlet groove 401, allowing the mounting blocks 104 to move to the left and enter the rotating groove 402. The mold core 101 is then rotated so that the mounting blocks 104 on both sides are horizontal with the mounting groove 403. The mounting blocks 104 are then pushed into the mounting groove 403, fixing the wire drawing component 1 inside the mold sleeve 201 and ensuring that the mold core 101 does not shake during wire drawing.

[0020] The fixing component 5 includes a fixing ring 501 and a thread 502. The fixing ring 501 is provided with a thread 502 on its outside. The fixing ring 501 and the thread 502 are rotatably engaged on the inlet groove 401, which facilitates the replacement of the die core 101 with different wire output effects at any time through the fixing ring 501 and the thread 502.

[0021] The working principle of this utility model: First, the mounting blocks 104 on both sides are introduced through the inlet groove 401, so that the mounting blocks 104 move to the left and enter the rotating groove 402. The mold core 101 is rotated so that the mounting blocks 104 on both sides are horizontal with the mounting groove 403. The mounting blocks 104 are pushed into the mounting groove 403, and the wire drawing assembly 1 is fixed inside the mold sleeve 201. Then, the fixing assembly 5 is rotated and screwed into the inlet groove 401. Next, the metal wire is guided into the wire outlet 102 through the wire inlet 103, and at the same time, lubricant is added from the lubrication holes 204 on both sides and dripped onto the surface of the wire, so that the wire initially contacts the inner wall of the die core 101. The wire begins to be squeezed by the inner wall of the wire outlet 102 and gradually produces plastic deformation. Its diameter begins to decrease, and its length increases accordingly, thus completing the wire drawing operation. Finally, during the wire drawing process, the friction between the wire and the inner wall of the wire outlet 102 generates heat. This heat is dissipated through the first heat dissipation groove 202 and the second heat dissipation groove 203. Coolant is input from the inlet 302 into the water cooling tank 301 and output from the outlet 303. Because the top opening diameter of the inlet 302 is larger than the bottom opening diameter, and the bottom opening diameter of the inlet 302 is larger than the opening diameter of the outlet 303, the outflow velocity is greater than the inflow velocity. The flowing coolant carries away the heat, cooling the mold sleeve 201 and the mold core 101.
