Description

Technical Field

[0001] This utility model relates to the field of wire drawing die technology, and in particular to a wire drawing die with a diamond coating. Background Technology

[0002] Wire drawing dies are tools used in metal wire production to draw metal to achieve the required size and shape. The principle is that under the action of external force, the metal is forced through the die, and the cross-sectional area of ​​the metal is compressed, thereby obtaining the required cross-sectional shape and size. They are widely used in high-precision wires required for electronic devices, radar, television, instruments and aerospace, as well as for drawing tungsten wire, molybdenum wire, stainless steel wire, wire and cable wire and various alloy wires.

[0003] Applying a diamond coating to the surface of wire drawing dies can increase their wear resistance. Existing wire drawing dies work by directly passing the wire through the die hole and using external force to pull the wire, thus changing its size. During the wire drawing process, due to the smooth structure of the die's outer surface, the die is unstable on the worktable. When the die is subjected to resistance from the wire and vibrates or shakes on the worktable, the stretching axis and the center line of the die hole are not aligned, leading to increased wear between the wire and the die. As a result, the wire drawing quality gradually deteriorates during production, and the die is prone to wear and breakage. Utility Model Content

[0004] This invention proposes a wire drawing die with a diamond coating to solve the problem that the existing drawing axis and the center line of the die hole are not on the same line, resulting in large wear between the wire and the die.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A wire drawing die with a diamond coating includes a die body, a mounting hole on the surface of the die body, a die core fixed in the mounting hole, a wire drawing hole in the center of the die core, a fixing seat on the outside of the die body, a slot for accommodating the die body on the front surface of the fixing seat, a support seat on the outside of the fixing seat, a placement groove for limiting the fixing seat on the top of the support seat, a limiting groove on the top of the support seat, and a locking rod that cooperates with the limiting groove on the outer wall of the fixing seat.

[0007] Preferably, a liquid tank is provided on the inner side of the slot, and multiple heat dissipation vents are provided on one side of the liquid tank.

[0008] Preferably, the side wall of the fixed base is provided with a liquid inlet and a liquid outlet, a second conduit is threaded to one side of the liquid inlet, and a first conduit is threaded to one side of the liquid outlet.

[0009] Preferably, the top of the support base is further provided with a positioning groove, a guide seat is placed on the top of the positioning groove, and a pin hole is provided on the top of the positioning groove.

[0010] Preferably, the top of the guide seat has a wire channel, the bottom of the wire channel is arc-shaped, and the bottom of the guide seat is fixed with multiple pins, which cooperate with pin holes.

[0011] Preferably, the center line of the guide seat and the axis of the wire drawing hole are on the same straight line.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] By setting a fixed seat on the outside of the mold body, and a support seat on the outside of the fixed seat, the support seat limits the mold body and ensures that the stretching axis and the center line of the mold hole are aligned. When the fixed seat, the support seat and the mold body work together, they form a stable mechanical system. The fixed seat provides an initial stable support point for the mold body, so that the mold body will not have obvious displacement or shaking when subjected to tension, making the wire drawing process smoother. This ensures the quality and precision of the wire drawing products, helps to improve production efficiency, and reduces scrap and defective products caused by product quality problems.

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figures 1-6 The diagram shows a diamond-coated wire drawing die, comprising a die body 1. The surface of the die body 1 has mounting holes 13, in which a die core 14 is fixed. A wire drawing hole 15 is formed in the center of the die core 14. A fixing seat 2 is provided on the outside of the die body 1. The front surface of the fixing seat 2 has a slot 10 for accommodating the die body 1. A support seat 6 is provided on the outside of the fixing seat 2. The top of the support seat 6 has a placement groove 63 for limiting the fixing seat 2. The top of the support seat 6 also has a limiting groove 61. The outer wall of the fixing seat 2 is provided with a groove that matches the limiting groove 61. The clamping rod 9 is combined with the bottom of the fixing seat 2, which is flat and placed on top of the placement groove 63 to ensure that the fixing seat 2 does not roll. It is worth noting that a diamond coating is combined on the surface of the mold body 1 and the mold core 14. The diamond coating surface is very smooth and has an extremely low coefficient of friction, which can effectively resist wear, maintain the shape and dimensional accuracy of the mold, and reduce mold failure caused by wear. Effective heat dissipation can reduce the temperature gradient of the mold during operation, reduce mold deformation caused by thermal expansion and contraction, and improve the dimensional accuracy and stability of the mold.

[0024] In this embodiment, during the wire drawing operation, the mold body 1 is placed into the slot 10, and then the bottom of the fixing seat 2 is placed on the top of the placement slot 63. The clamping rod 9 is placed into the limiting slot 61. At this time, the fixing seat 2 cannot move in the placement slot 63. The movement of the mold body 1 in the front-back and left-right directions is restricted by the support seat 6. Finally, the support seat 6 is clamped on the worktable of the wire drawing machine by a mechanical clamp. The mechanical clamping of the planar structure is already existing technology and will not be described in detail here.

[0025] like Figures 1-3 as well as Figure 5As shown, a liquid tank 11 is provided on the inner side of the slot 10, and multiple heat dissipation vents 8 are provided on one side of the liquid tank 11. The side wall of the fixing seat 2 is provided with a liquid inlet 7 and a liquid outlet 71. A second conduit 4 is threaded to one side of the liquid inlet 7, and a first conduit 3 is threaded to one side of the liquid outlet 71. During the wire drawing process, the second conduit 4 is connected to the pipe of the external cooling pump. The cooling pump draws coolant, which enters the liquid inlet 7 through the second conduit 4, and then enters the fixing seat 2. The coolant accumulates in the liquid tank 11 in the fixing seat 2. The coolant absorbs the heat of the mold body 1, avoiding the problem of heat not being dissipated during the wire drawing process, thus facilitating timely heat dissipation of the mold body 1. The coolant is continuously input into the fixing seat 2 and flows outward from the liquid outlet 71 and the heat dissipation vents 8, carrying away the heat in time.

[0026] like Figures 1-5 As shown, the top of the support base 6 is also provided with a positioning groove 62, and a guide seat 5 is placed on the top of the positioning groove 62. A pin hole 64 is provided on the top of the positioning groove 62. A wire channel 51 is provided on the top of the guide seat 5. The bottom of the wire channel 51 is arc-shaped. Multiple pins 12 are fixed at the bottom of the guide seat 5. The pins 12 cooperate with the pin hole 64. The center line of the guide seat 5 is on the same straight line as the axis of the wire drawing hole 15. During the wire drawing process, one end of the wire is inserted into the wire channel 51 from above and then pushed into the wire drawing hole 15. The end of the wire passes through the wire drawing hole 15 and is pulled by a tool. The wire passes through the wire channel 51 and then through the wire drawing hole 15. The wire channel 51 guides the movement trajectory of the wire, thereby ensuring that the axis of the wire and the center line of the wire drawing hole 15 are on the same straight line before the wire enters the wire drawing hole 15. This reduces the excess friction between the wire and the wire drawing hole 15, improves the wire drawing efficiency, and protects the wire drawing die at the same time.

[0027] 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, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
