Description

Technical Field

[0001] This utility model relates to the field of stranding mold technology, specifically to the structure of a high-precision ultra-fine tungsten wire cable stranding mold. Background Technology

[0002] With the rapid development of science and technology, the demand for high-precision ultra-fine tungsten wire cables is increasing in many high-tech fields, such as electronic information, aerospace, and medical devices. These cables play a key role in various precision equipment and high-end products due to the excellent properties of tungsten wire, such as high melting point, high strength, and low resistance.

[0003] Currently, in the production of high-precision ultra-fine tungsten wire cables, multiple high-precision ultra-fine tungsten wires are usually passed through a stranding die, and then stranded together to form a cable using a stranding machine. During the stranding process, the ultra-fine tungsten wires will frequently rub against the surface of the die. Due to the high hardness of the tungsten wires, the die will experience significant wear. The wear of the die will not only shorten its service life and increase production costs, but will also cause the die to deform due to friction and heating, resulting in reduced precision. Furthermore, it will alter the physical properties of the tungsten wires, making them prone to breakage, and surface oxidation will affect performance.

[0004] Therefore, it is of great importance to design a high-precision, ultra-fine tungsten wire cable stranding mold structure to solve the above-mentioned defects. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model designs a high-precision ultra-fine tungsten wire cable stranding mold structure. This stranding mold structure aims to solve the technical problems that occur when producing high-precision ultra-fine tungsten wire cables using existing stranding molds. The ultra-fine tungsten wire frequently rubs against the mold surface, causing mold wear due to the high hardness of the tungsten wire. This not only shortens the mold's service life and increases costs, but also causes mold deformation due to frictional heating, resulting in reduced precision and altering the physical properties of the tungsten wire.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-precision ultra-fine tungsten wire cable stranding mold structure includes a support base, a water storage tank fixedly installed on the top of the support base, a cooling mechanism fixedly installed on the outside of the water storage tank, a cooling plate fixedly installed on the top of the water storage tank, and multiple sets of mounting mold sleeves installed inside the cooling plate, with tungsten steel inner molds fixedly connected inside each set of mounting mold sleeves.

[0008] The cooling mechanism includes a cooling box fixedly installed on the outside of the water storage tank. The back of the cooling box is connected to the inside of the water storage tank. Multiple sets of heat dissipation fins are fixedly connected to the inside of the cooling box, and the rear ends of the multiple sets of heat dissipation fins extend into the inside of the water storage tank. Two sets of cooling fans are fixedly installed on the front of the multiple sets of heat dissipation fins. A heat dissipation tube frame is embedded inside the cooling plate and outside the multiple sets of mounting sleeves. A pump is fixedly installed at the bottom of the cooling box. The input end of the pump is connected to the inside of the cooling box through a water pumping pipe. The output end of the pump is fixedly connected to the heat dissipation tube frame through a water supply pipe. The left end of the top of the cooling box is fixedly connected to the heat dissipation tube frame through a return water pipe.

[0009] As a preferred embodiment of this utility model, the top of the cooling tank is provided with a water inlet, the outer side of the water inlet is threaded with a cap, and a drain pipe is fixedly installed at the bottom of the water storage tank.

[0010] As a preferred embodiment of this utility model, the cooling box is fixedly connected to the left and right sides with mounting feet, and multiple sets of mounting feet are fixedly connected to the water storage tank by mounting screws, and fastening springs are sleeved on the outside of the multiple sets of mounting screws.

[0011] As a preferred embodiment of this utility model, fixing holes are provided at the four corners of the bottom of the support base, and a positioning groove adapted to the cooling plate is provided on the top of the water storage tank.

[0012] As a preferred embodiment of this utility model, locking blocks are slidably connected to both the left and right ends of the mounting mold sleeve. Locking holes are provided inside the cooling plate at positions corresponding to the locking blocks. Reset springs are fixedly connected inside the mounting mold sleeve at opposite ends of the two sets of locking blocks. Operating handles are fixedly connected to the outer sides of the two sets of locking blocks. Operating grooves are provided on the front of the mounting mold sleeve at positions corresponding to the operating handles.

[0013] As a preferred embodiment of this utility model, V-shaped guide grooves are provided at both the front and rear ends of the mounting mold sleeve, and an inlet groove is provided between the two sets of V-shaped guide grooves.

[0014] As a preferred embodiment of this utility model, a wire-holding groove is provided at the connection between the tungsten steel inner mold and the wire inlet groove, a wire-passing hole is provided at the center of the tungsten steel inner mold, and tapered grooves are provided on both the front and rear sides of the tungsten steel inner mold and at the front and rear ends of the wire-passing hole.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, through the coordinated design of the water storage tank, cooling mechanism and cooling plate, the cooling water stored in the water storage tank flows into the cooling box during the stranding process. The water in the cooling box increases the heat dissipation area through the heat dissipation fins. At the same time, the cooling fan accelerates the air flow and improves the heat dissipation efficiency, thereby maintaining the cooling effect of the cooling water. The pump draws water from the cooling box through the water suction pipe and then sends the cooling water into the heat dissipation tube frame through the water delivery pipe. The cooling water in the heat dissipation tube frame flows around the mounting mold sleeve. After absorbing heat, it flows back to the cooling box through the return water pipe to form a circulation. This effectively reduces the temperature of the mold during the working process, prevents deformation and precision reduction caused by high temperature, extends the service life of the mold, reduces production costs, and avoids changes in the physical properties of the tungsten wire that affect its performance.

[0017] 2. In this utility model, the installation mold sleeve and the tungsten steel inner mold are designed to be compatible, making installation and disassembly of the mold sleeve convenient and improving maintenance ease. The high-precision ultra-fine tungsten wire is first guided to the wire inlet groove through the V-shaped guide groove for easy threading, and then guided into the threading hole in the tungsten steel inner mold through the wire clamping groove. It is then guided into the stranding machine for stranding using the conical groove. Due to its high hardness, the tungsten steel inner mold can effectively resist the wear generated by the ultra-fine tungsten wire during the stranding process, extending the service life of the mold. At the same time, the high hardness and stability of the tungsten steel inner mold ensure the accuracy of the stranding process, so that the high-precision ultra-fine tungsten wire cable produced meets the strict quality requirements. Moreover, the tungsten steel material has good thermal stability, and it can maintain the stability of its shape and size even in long-term operation or high-temperature environment, further ensuring the quality of the stranded wire. The conical groove design not only reduces the friction of the tungsten wire during stranding, but also ensures the uniformity and stability of the stranded wire, avoiding changes in the physical properties of the tungsten wire or breakage caused by friction.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example: Please refer to Figures 1-5 This utility model provides a technical solution:

[0026] The high-precision ultra-fine tungsten wire cable stranding mold structure includes a support base 1, a water storage tank 2 fixedly installed on the top of the support base 1, a cooling mechanism 3 fixedly installed on the outside of the water storage tank 2, a cooling plate 4 fixedly installed on the top of the water storage tank 2, and multiple sets of mounting mold sleeves 5 installed inside the cooling plate 4. Tungsten steel inner molds 6 are fixedly connected inside the multiple sets of mounting mold sleeves 5.

[0027] First, in this embodiment, the specific structure of the cooling mechanism 3 is as follows:

[0028] The cooling mechanism 3 includes a cooling box 301 fixedly installed on the outside of the water storage tank 2. The back of the cooling box 301 is connected to the inside of the water storage tank 2. Multiple sets of heat dissipation fins 302 are fixedly connected to the inside of the cooling box 301, and the rear ends of the multiple sets of heat dissipation fins 302 extend into the inside of the water storage tank 2. Two sets of cooling fans 303 are fixedly installed on the front of the multiple sets of heat dissipation fins 302. A heat dissipation tube frame 304 is embedded inside the cooling plate 4 and outside the multiple sets of mounting molds 5. A pump 305 is fixedly installed at the bottom of the cooling box 301. The input end of the pump 305 is connected to the inside of the cooling box 301 through a water pumping pipe 306. The output end of the pump 305 is fixedly connected to the heat dissipation tube frame 304 through a water supply pipe 307. The left end of the top of the cooling box 301 is fixedly connected to the heat dissipation tube frame 304 through a return water pipe 308. First, the support base 1 is installed and fixed in front of the stranding machine, and then the mounting molds 5 are installed on the cooling box 301. Inside plate 4, multiple high-precision ultra-fine tungsten wires are passed through multiple sets of tungsten steel inner molds 6 and twisted together using a stranding machine to form a cable. During this process, the cooling water stored in the water storage tank 2 flows into the cooling tank 301. The water in the cooling tank 301 increases the heat dissipation area through the heat dissipation fins 302, while the cooling fan 303 accelerates the airflow and improves the heat dissipation efficiency, thereby maintaining the cooling effect of the cooling water. The pump 305 draws water from the cooling tank 301 through the water pumping pipe 306, and then sends the cooling water into the heat dissipation tube frame 304 through the water delivery pipe 307. The cooling water in the heat dissipation tube frame 304 flows around the mounting mold sleeve 5, absorbs heat, and then flows back to the cooling tank 301 through the return water pipe 308 to form a circulation. This effectively reduces the temperature of the mold during operation, prevents deformation and precision reduction caused by high temperature, extends the service life of the mold, reduces production costs, and avoids changes in the physical properties of the tungsten wire that affect its performance.

[0029] Furthermore, a water inlet is provided on the top of the cooling tank 301, and a cap 309 is threadedly connected to the outside of the water inlet. A drain pipe 310 is fixedly installed at the bottom of the water storage tank 2. Water is added into the cooling tank 301 through the water inlet and sealed with the cap 309. When drainage is required, the valve of the drain pipe 310 is opened.

[0030] Then, mounting feet 311 are fixedly connected to both sides of the cooling box 301. Multiple sets of mounting feet 311 are fixedly connected to the water storage tank 2 by mounting screws 312. Fastening springs 313 are sleeved on the outside of the multiple sets of mounting screws 312. The mounting feet 311 are fixed to the water storage tank 2 by mounting screws 312. The fastening springs 313 provide additional fastening force to ensure a stable connection between the cooling box 301 and the water storage tank 2.

[0031] Furthermore, fixing holes 101 are provided at the four corners of the bottom of the support base 1, and the top of the water storage tank 2 is provided with a positioning groove 401 that is compatible with the cooling plate 4. The support base 1 is fixed in a suitable position in front of the stranding machine through the fixing holes 101, and the cooling plate 4 is installed in the positioning groove 401 of the water storage tank 2 and welded to achieve installation and positioning.

[0032] Secondly, locking blocks 501 are slidably connected to both ends of the mounting sleeve 5. Locking holes are opened inside the cooling plate 4 at positions corresponding to the locking blocks 501. Return springs 502 are fixedly connected inside the mounting sleeve 5 at opposite ends of the two sets of locking blocks 501. Operating handles 503 are fixedly connected to the outer sides of the two sets of locking blocks 501. Operating grooves 504 are opened on the front of the mounting sleeve 5 at positions corresponding to the operating handles 503. The locking blocks 501 are pushed by the operating handles 503 to lock into the locking holes of the cooling plate 4. The return springs 502 provide elasticity to ensure the stability of the locking blocks 501, which facilitates the quick installation and removal of the mounting sleeve 5 and further improves the convenience of maintenance.

[0033] Finally, V-shaped guide grooves 505 are provided at both the front and rear ends of the mounting mold sleeve 5, and a wire inlet groove 506 is provided between the two sets of V-shaped guide grooves 505. A wire clamping groove 601 is provided at the connection between the tungsten steel inner mold 6 and the wire inlet groove 506. A wire threading hole 602 is provided at the center of the tungsten steel inner mold 6. Conical grooves 603 are provided on both the front and rear sides of the tungsten steel inner mold 6 and at the front and rear ends of the wire threading hole 602. The high-precision ultra-fine tungsten wire is first guided to the wire inlet groove 506 through the V-shaped guide grooves 505 for easy threading, and then guided into the wire threading hole 602 in the tungsten steel inner mold 6 through the wire clamping groove 601. Finally, it is guided into the stranding machine for stranding using the conical grooves 603. Due to its high hardness, the steel inner mold 6 can effectively resist the wear generated by the ultra-fine tungsten wire during the stranding process, extending the service life of the mold. At the same time, the high hardness and stability of the tungsten steel inner mold 6 ensures the precision of the stranding process, so that the high-precision ultra-fine tungsten wire cable produced meets the strict quality requirements. Moreover, the tungsten steel material has good thermal stability, and can maintain its shape and size stability even in long-term operation or high-temperature environment, further ensuring the quality of the stranded wire. The design of the conical groove 603 not only reduces the friction of the tungsten wire during stranding, but also ensures the uniformity and stability of the stranded wire, avoiding changes in the physical properties of the tungsten wire or breakage caused by friction.

[0034] In this embodiment, the specific implementation scenario is as follows: First, the support base 1 is installed and fixed in front of the stranding machine. Then, the mounting mold sleeve 5 is installed inside the cooling plate 4. Next, multiple high-precision ultra-fine tungsten wires are passed through multiple sets of tungsten steel inner molds 6. The high-precision ultra-fine tungsten wires are first guided to the wire inlet groove 506 through the V-shaped guide groove 505 for easy wire threading. Then, they are guided into the wire threading hole 602 inside the tungsten steel inner mold 6 through the wire clamping groove 601, and guided into the stranding machine for stranding using the conical groove 603. The tungsten steel inner mold 6, due to its high hardness, can effectively resist the wear generated by the ultra-fine tungsten wires during the stranding process, extending the service life of the mold. At the same time, the high hardness and stability of the tungsten steel inner mold 6 ensures the accuracy during the stranding process, so that the produced high-precision ultra-fine tungsten wire cables meet strict quality requirements. Moreover, tungsten steel material has good thermal stability, and even under long-term operation or high-temperature environment, it can maintain the stability of its shape and size, further ensuring the quality of the stranded wire. The design of the conical groove 603 not only reduces the tungsten wire wear, but also ensures the quality of the stranded wire. The friction of the wire during stranding ensures the uniformity and stability of the stranded wire, preventing changes in the physical properties or breakage of the tungsten wire due to friction. During this process, the cooling water stored in the water tank 2 flows into the cooling tank 301. The water in the cooling tank 301 increases the heat dissipation area through the heat dissipation fins 302, while the cooling fan 303 accelerates the airflow, improving the heat dissipation efficiency and maintaining the cooling effect of the cooling water. The pump 305 draws water from the cooling tank 301 through the water suction pipe 306, and then sends the cooling water into the heat dissipation tube frame 304 through the water delivery pipe 307. The cooling water in the heat dissipation tube frame 304 flows around the mounting mold sleeve 5, absorbs heat, and then flows back to the cooling tank 301 through the return water pipe 308 to form a cycle. The entire operation process is simple and convenient. This utility model optimizes the wear resistance, thermal stability, and low friction design of the tungsten steel inner mold 6, combined with an efficient circulating cooling system, to achieve efficient, low-loss, and high-precision stranding production of high-precision ultra-fine tungsten wire cables, significantly improving the product qualification rate and extending the mold life.
