Description

Technical Field

[0001] This application relates to the field of metal wire drawing technology, and in particular to a metal cold working wire drawing device. Background Art

[0002] In many fields, different products have specific requirements for the thickness, length and other dimensions of metal wires. Therefore, drawing tungsten wire can meet special design and functional requirements. Moreover, a reasonable drawing process can improve the toughness and ductility of metals to a certain extent. However, most existing wire drawing processes use hot working operations. During the hot working process, due to factors such as uneven thermal expansion and deformation of metals at high temperatures, it is difficult to accurately control the final size and shape of the tungsten wire. Furthermore, high temperatures can cause oxidation and decarburization on the surface of the tungsten wire, resulting in oxide scale or other defects on the surface, affecting the surface finish and quality, and thus making it difficult to meet the application requirements.

[0022] Reference Figures 1-8 A metal cold drawing device includes a machine base 1, a roller assembly 2, a die base assembly 3, a lubrication assembly 4, a coating assembly 5, an electroplating assembly 6, and a spraying assembly 7. The machine base 1 has an inlet end and an outlet end on both sides. The lubrication assembly 4, the coating assembly 5, the electroplating assembly 6, and the spraying assembly 7 are distributed sequentially from the inlet end to the outlet end. Several roller assemblies 2 are provided and spaced apart along the length of the machine base 1. Several die base assemblies 3 are provided and located between two adjacent sets of roller assemblies 2. The lubrication assembly 4 is located on the side of the machine base 1 near the inlet end. The spraying assembly 7 is located on the side of the machine base 1 near the outlet end. The coating assembly 5 and the electroplating assembly 6 are located between the lubrication assembly 4 and the spraying assembly 7. The lubrication assembly 4 includes a housing 41, a pump body component 42, and a liquid outlet pipe 43. The housing 41 has openings 411 on both sides. A material placement platform 412 is provided inside the housing 41 near the traction roller component 2. The material placement platform 412 has an opening. The housing 41 is filled with lubricating fluid. The pump body component 42 is installed inside the housing 41 and connected to the liquid outlet pipe 43. The output end of the liquid outlet pipe 43 is located above the material placement platform 412. The lubricating fluid is a lubricating emulsion used for the initial lubrication of the wire. The pump body component 42 is a circulating pump in the prior art, which can realize the recycling of the lubricating fluid in the housing 41. By lubricating, the friction between the wire and the die base component 3 can be reduced, making the wire drawing process smoother, reducing the pulling force required for wire drawing, and reducing equipment energy consumption. The coating component 5 includes a liquid tank 51 filled with an adhering solution. The liquid tank 51 has wire-threading tubes 52 on both sides that communicate with the interior. The adhering solution is a graphite emulsion for wire drawing, which coats the wire with a graphite coating. The graphite coating has good lubrication properties, which can further reduce friction and make the re-drawing process smoother. It helps to improve the surface quality and dimensional accuracy of the tungsten wire. In addition, the graphite coating can form a uniform protective film on the surface of the wire, which can improve the strength, hardness and wear resistance of the tungsten wire. The electroplating assembly 6 includes a collection tank 61 and a first push rod component 62. The collection tank 61 is filled with electrolyte and can be energized. The electrolyte is a nickel plating solution, which is used to perform chemical plating on the wire. A support plate 11 is provided on the machine base 1 and is located above the collection tank 61. The first push rod component 62 is provided on the support plate 11. The piston end of the first push rod component 62 extends through the support plate 11 into the collection tank 61. A roller component 621 is installed at the bottom of the first push rod component 62. The outer circumference of the roller component 621 abuts against the wire, reducing damage to the outer circumference of the wire. By plating nickel, a dense protective film can be formed on the surface of the wire, isolating the wire from air and other corrosive media, improving the wire's corrosion resistance, and extending its service life. The spraying assembly 7 includes a support 71, a slider 72, and a spray gun 73. The support 71 has two sets of spray guns that are staggered relative to the two ends of the machine base 1. The spray gun 73 is mounted on the slider 72. The support 71 has a groove, and the slider 72 is movably mounted in the groove. The movement of the slider 72 in the groove can adjust the spray gun 73 to a suitable position. The two sets of spray guns 73 form a spraying area for the wire. The two sets of spray guns 73 can uniformly spray the outer periphery of the wire. The spraying material of the spray gun 73 can be ceramic coating material or metal alloy coating material. The thermal spray coating can have good high temperature resistance, which can protect the wire from oxidation, deformation and other problems in high temperature environment, thus broadening the application range of the wire and meeting different engineering application needs. The die base assembly 3 has a wire drawing die component 31 through which the wire passes. The diameter of the holes in the several wire drawing die components 31 is different. The wire drawing die component 31 located at the feed end of the machine base 1 is the largest and gradually decreases along the direction of the discharge end.

[0023] Based on the above structure, the wire to be drawn is pulled from the inlet end of the machine 1 to the outlet end. First, the wire is located on the housing 41 of the lubrication assembly 4. Lubricating fluid from the housing 41 is sprayed onto the surface of the wire through the outlet pipe 43, thus lubricating the wire. Then, with the cooperation of the traction roller assembly 2, the wire moves to the position of the coating assembly 5 and enters the liquid tank 51 through the threading pipe 52. Since the liquid tank 51 is filled with an adhering solution, when the wire leaves the liquid tank 51 through another set of threading pipes 52, the surface of the wire is coated with the adhering solution and enters the first set of die base assemblies 3 for preliminary wire drawing. Subsequently, with the cooperation of the next set of traction roller assemblies 2, it moves to the electroplating assembly 6. Inside the liquid tank 61, when the wire is located on the liquid collection tank 61, the first push rod component 62 squeezes the wire, immersing it in the liquid collection tank 61. This causes the wire to be coated with electrolyte on its outer periphery. With the cooperation of the next set of traction roller components 2, the wire re-enters the die base assembly 3 for another wire drawing operation. Subsequently, the wire moves to the position of the spraying assembly 7. The spray gun component 73 in the spraying assembly 7 performs thermal spraying on the outer periphery of the wire, thereby protecting the outer periphery of the wire. This completes the cold working wire drawing process without heating the wire, solving the problem that slight deviations in temperature control during hot working can lead to fluctuations in metal properties, resulting in deviations in the dimensional accuracy of the wire.

[0024] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 5 It also includes a pulling assembly 8, which is located between the spraying assembly 7 and the pulling roller component 2. The pulling assembly 8 is used to pull the filament, thereby adjusting the tension of the filament when it moves. The traction assembly 8 includes a lead screw component 81, a drive motor 82, a bearing seat 83, and a roller component 84. The machine base 1 has a receiving groove 12. The lead screw component 81 is rotatably disposed in the receiving groove 12. One end of the lead screw component 81 extends to the outside of the machine base 1 and is connected to the drive motor 82. The drive motor 82 is a servo drive motor in the prior art. It is connected to the lead screw component 81 through a coupling to provide power for the rotation of the lead screw component 81. A lead screw bearing seat is connected between the lead screw component 81 and the receiving groove 12. The support seat 83 is mounted on the lead screw assembly 81, and the rotating roller assembly 84 is disposed on the support seat 83. Through the cooperation of the support seat 83 and the lead screw assembly 81, the rotating roller assembly 84 can move relative to the lead screw assembly 81 along its length. The rotating roller assembly 84 is a rotatable roller in the prior art. When the lead screw located on the rotating roller assembly 84 is pulled, the rotation of the lead screw assembly 81 causes the support seat 83 to drive the rotating roller assembly 84 to move in the rotation direction of the lead screw assembly 81, thereby changing the position of the wire and increasing the tension when pulling the wire. Appropriate tension can make the wire deform evenly during the pulling process, preventing local overstretching or understretching, thus ensuring the consistency of the wire diameter. Furthermore, the rotation of the lead screw assembly 81 can achieve precise tension adjustment, which helps to stabilize the wire's stretching length and ensure that the wire reaches the specified length standard during the production process, reducing length deviation.

[0025] In one embodiment, refer to Figure 1. Figure 2 , Figure 7 , Figure 8 and Figure 9 The mold base assembly 3 also includes a placement base 32, one end of which is mounted on the machine base 1. The placement base 32 has a placement groove 321, which allows the wire drawing mold component 31 to be movably installed in the placement groove 321. The two sides of the storage base 32 are also provided with perforations 322, which are connected to the placement groove 321. The diameter of the perforation 322 is larger than the diameter of the wire drawing die component 31, and can accommodate the passage of the wire. The wire drawing die component 31 includes a mounting block 311 and a wire module 312. The mounting block 311 has a mounting groove for mounting the wire module 312. The wire module 312 is used to extrude and shape the wire, thereby changing the size of the wire. The wire drawing die component 31 can be adjusted according to actual conditions through a movable mounting method. The mounting block 311 also has a liquid storage chamber 3111. The wire module 312 has an overflow hole 3121 communicating with the liquid storage chamber 3111. The top of the mounting block 311 is provided with a liquid inlet 3112. The other end of 2 is connected to the liquid storage chamber 3111. The liquid inlet 3112 is designed to facilitate the operator to input external oil into the liquid storage chamber 3111. The oil flows through the liquid storage chamber 3111 to the overflow hole 3121 and enters the wire module 312. This allows the wire module 312 to lubricate the wire when applying shaping pressure, thereby avoiding direct friction between the metal wire surface and the wire module 312, which would scratch the metal wire surface, form scratches, abrasions and other defects, reduce the surface quality of the metal wire and affect its subsequent performance. The mounting block 311 is provided with an elastic sealing component 33, which includes a pad 331, an elastic element 332, a support rod 333, and a pressure plate 334. The pad 331 is movably disposed in the liquid storage cavity 3111. One end of the elastic element 332 is connected to the pad 331, and the other end is connected to the end face of the liquid storage cavity 3111. Several elastic elements 332 are provided and evenly distributed around the pad 331. The pad 331 is made of rubber material, and the elastic element 332 is a pressure spring or a telescopic spring in the prior art. Through the connection between the elastic element 332 and the pad 331, the pad 331 can be moved according to the elastic deformation characteristics of the elastic element 332 itself. Several support rods 333 are provided. Each support rod 333 is connected to the pad 331 and located within the elastic element 332. The other end of each support rod 333 extends to the outside of the mounting block 311 and connects to the pressure plate 334. The support rods 333, located within the elastic element 332, guide the movement of the pad 331. Furthermore, the elastic element 332 deforms during elastic deformation, thus the support rods 333 act as guides, preventing the elastic element 332 from causing the pad 331 to shift position. Through the cooperation of the elastic element 332 and the support rods 333, the pad 331 is able to block or move away from the overflow hole 3121. When the liquid storage chamber 3111 is filled with useful liquid... When the lubricating liquid is present, the liquid pushes the pad 331, thereby compressing the elastic element 332 and causing the pad 331 to move closer to the top end face of the liquid storage cavity 3111. As the liquid in the liquid storage cavity 3111 gradually decreases, the pressure on the elastic element 332 gradually decreases, thereby resetting and moving the pad 331 away from the end face of the liquid storage cavity 3111. During the movement of the pad 331, it squeezes the liquid in the liquid storage cavity 3111, thereby allowing the liquid to enter the wire module 312 through the liquid storage cavity 3111. At the same time, the operator can also accelerate the movement speed of the pad 331 by squeezing the pressure plate 334.

[0026] In one embodiment, reference is made to Figure 1-Figure 3 The lubrication assembly 4 also includes a clamping component 44, which includes a shaft 441, a support plate 442, a screw 443, and a clamping seat 444. The shaft 441 is located on the top of the housing 41, the support plate 442 is sleeved on the shaft 441, the screw 443 is threaded to the support plate 442, and one end of the screw 443 is connected to the clamping seat 444. The clamping seat 444 has an arc-shaped groove for accommodating the wire. The clamping seat 444 is located above the feeding table 412, forming a clamping area between the clamping seat 444 and the feeding table 412. A handwheel is connected to the other end of the screw 443. Rotation of the screw 443 moves the clamping seat 444 closer to or further away from the feeding table 412. When the wire passes through the housing 41, it is positioned between the clamping seat 444 and the feeding table 412, thus limiting the wire's movement and preventing it from wobbling. Furthermore, since different processing requirements necessitate different wire sizes, the clamping seat 444 is positioned between the clamping seat 444 and the feeding table 412. By connecting the clamping seat 444 to the screw 443, the operator can rotate the screw 443, thereby changing the position of the clamping seat 444. This avoids the clamping seat 444 in a fixed position limiting the size of the wire. At the same time, by sleeved the support plate 442 on the shaft 441, the support plate 442 can drive the screw 443 to rotate along the circumference of the shaft 441. This allows the angle of the clamping component 44 to be adjusted according to the actual situation, improving the flexibility of clamping.

[0027] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 6 It also includes a diameter measuring component 9. A support plate 442 is provided on the bearing seat 83. The diameter measuring component 9 is set on the support plate 442. The diameter measuring component 9 is located between the traction roller component 2 and the spraying component 7. The diameter measuring component 9 is an existing wire diameter detector. When the wire passes through the diameter measuring component 9, its size can be detected, thereby determining whether the size of the wire meets the processing accuracy requirements. This makes it easier for the operator to adjust the wire drawing die component 31 and achieve stable accuracy of the lead screw after processing.

[0028] In one embodiment, reference is made to Figure 1 , Figure 2 , Figure 6 and Figure 10 The spraying assembly 7 also includes a second push rod component 74, which is located inside the machine base 1. The piston end of the second push rod component 74 is connected to the slider 72. Through the cooperation of the second push rod component 74, the slider 72 moves relative to the slide along the length of the slide groove. The second push rod component 74 drives the slider 72, which is equipped with the spray gun component 73, to move, so that the spray gun component 73 can uniformly spray the outer periphery of the filament during the movement. Furthermore, the position of the spray gun component 73 can be changed according to the thickness of the filament, thereby improving the flexibility of use of the spraying assembly 7. The second push rod component 74 adopts a pneumatic or electric push rod as used in the prior art.

[0029] In one embodiment, reference is made to Figure 1 , Figure 2 , Figure 4 and Figure 11A sealing gasket 53 is installed inside the threading tube 52. The sealing gasket 53 has slits 531. Several slits 531 are provided and evenly distributed along the circumference of the sealing gasket 53. The slits 531 allow the part between the slits to produce a certain elastic deformation when the thread passes through the sealing gasket 53, thereby accommodating the passage of the thread and better conforming to the surface of the thread with different diameters. This ensures that a good seal is formed between the thread and the threading tube 52 regardless of the thickness of the thread, preventing liquid or gas leakage.

[0030] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 6 It also includes a winding roller component 13, which is mounted on the machine base 1 and located at the discharge end of the machine base 1. The winding roller component 13 is a winding roller that is rotated by a motor in the prior art, and is used to collect the tungsten wire after drawing by rotating, so that the tungsten wire can be rolled up.
