Description

Technical Field

[0001] This invention relates to the field of cable processing, specifically to a production line for high-temperature resistant cables for aerospace applications and its manufacturing method. Background Technology

[0002] Wires and cables are wire products used to transmit electrical energy, information, and realize electromagnetic energy conversion. In a broad sense, wires and cables are also simply referred to as cables. In a narrow sense, cables refer to insulated cables, which can be defined as: an assembly consisting of one or more insulated conductors, and their respective possible covering layers, overall protective layer, and outer sheath. Cables may also have additional uninsulated conductors. Aerospace cables are mainly used in installation lines for aircraft, spacecraft, or in harsh environments such as high temperature and strong corrosion, and have good high temperature resistance and corrosion resistance.

[0003] The production process of the cable production line is divided into the following steps: First, copper and aluminum monofilaments are drawn, and then the monofilaments are annealed. When the copper and aluminum monofilaments are heated to a certain temperature, the monofilaments are recrystallized to improve their toughness and reduce their strength, so as to meet the requirements of wires and cables for conductive cores. After annealing, in order to improve the flexibility of wires and cables and facilitate laying and installation, the conductive core is made of multiple monofilaments twisted together. After the conductive core is twisted together, a solid insulation layer is extruded onto the surface of the conductive core.

[0004] In the above process, the insulation layer on the surface of the conductive core is extruded by an extruder. After extrusion, it needs to be water-cooled for molding. Water cooling can effectively accelerate the curing of the insulation layer to achieve the effect of rapid cooling and molding.

[0005] After passing through a water-cooling tank, existing cables are typically dried by blowing directly onto their surface with a fan or by using an oven. However, direct blowing of the fan onto the cable makes it difficult to completely cover the cable surface, and some areas may not achieve the desired drying effect. While oven drying can achieve a better drying effect, it requires heating the air, which consumes a lot of energy and results in high drying costs. Summary of the Invention

[0006] Based on this, the purpose of this invention is to provide a production line for high-temperature resistant cables for aerospace applications and its preparation method, so as to solve the technical problem that the surface moisture drying effect of general cables is not good after extrusion molding and passing through a water cooling tank.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a production line for high-temperature resistant cables for aerospace applications, comprising a cooling tank and a rotating roller, one end of the rotating roller being connected to a driving mechanism, the driving mechanism being connected to a first vibration mechanism, the first vibration mechanism comprising a fixed sleeve and a rotating shell, the fixed sleeve being connected to the driving mechanism, the rotating shell array being disposed on the outer wall of the fixed sleeve, a second vibration mechanism being disposed on one side of the first vibration mechanism, the second vibration mechanism comprising a first movable block, a second movable block and an elastic mechanism, the second movable block being inserted into the top of the first movable block, one end of the first movable block and the second movable block being respectively provided with an elastic mechanism, and a drying mechanism being disposed on one side of the second vibration mechanism.

[0008] The present invention is further configured such that the driving mechanism includes a first synchronous belt mechanism, a second synchronous belt mechanism and a rotating shaft, the first synchronous belt mechanism is connected to one end of the rotating roller, the first synchronous belt mechanism is connected to the rotating shaft, the number of rotating shafts is two, and the second synchronous belt mechanism is connected between the rotating shafts.

[0009] The invention is further configured such that the first vibration mechanism further includes a roller, the roller being disposed on the top of the rotating shell, and the surface of the roller protruding from the groove of the rotating shell.

[0010] The present invention is further configured such that the second vibration mechanism includes a fixing groove and a water leakage hole, the surfaces of the first movable block and the second movable block are provided with an arc-shaped fixing groove, and the side wall of the first movable block is provided with a water leakage hole.

[0011] The present invention is further configured such that the elastic mechanism includes a fixed base, a mounting block and a spring, the spring is disposed inside the fixed base, one end of the spring is connected to the mounting block, the elastic mechanism is divided into upper and lower groups, and the mounting blocks of the upper and lower groups are respectively connected to the second movable block and the first movable block.

[0012] The present invention is further configured such that a water collection tank is provided on one side of the cooling tank, and a fixed shell is provided on the top of the water collection tank, wherein the first vibration mechanism and the second vibration mechanism are both located inside the fixed shell.

[0013] The present invention is further configured such that the drying mechanism includes a mounting ring, an air outlet and an air inlet pipe, the mounting ring is mounted on one side of the water collection tank, the mounting ring has an air outlet inside, and the mounting ring has an air inlet pipe at its bottom.

[0014] The invention is further configured such that the surface of the rotating roller is provided with a groove, and the two sides of the fixed shell are provided with through grooves.

[0015] This invention also provides the following technical solution: a method for manufacturing high-temperature resistant cables for aerospace applications, wherein the specific operation steps are as follows:

[0016] Step 1: First, draw the copper monofilament, then anneal the monofilament. After annealing, twist the conductor regularly into a core. While twisting the conductor, use a compaction method to change the ordinary round shape into a fan shape.

[0017] Step 2: The stranded wire cores pass through an extruder. The molten plastic inside the extruder is extruded from the die opening and wrapped around the wire cores to form a continuous and dense insulation layer.

[0018] Step 3: After extrusion molding, the cable needs to be cooled and cured. The cable enters a cooling tank for cooling.

[0019] Step 4: When the cable moves in the cooling tank for cooling, the cable drives the rotating roller to rotate. The rotational force of the rotating roller is transported to the rotating shaft through the first synchronous belt mechanism. The first vibration mechanism and the second vibration mechanism on the rotating shaft vibrate and dehydrate the cable. As the rotating shaft rotates, the rotating shell also rotates. The cable is swept by the rotating shell and begins to shake up and down continuously. When the cable comes into contact with the first movable block and the second movable block, the up and down movement of the cable will cause the first movable block and the second movable block to continuously squeeze the spring. At this time, the elasticity of the spring will increase the up and down movement frequency of the cable, thereby increasing the shaking effect of the cable cooling water.

[0020] Step 5: After being dehydrated by the first and second vibration mechanisms, the cable passes through the drying mechanism, which further dries the cable. A fan supplies air to the installation ring through the air inlet pipe, and the drying air is sprayed out from the air outlet, which can cover the circumference of the cable and blow away the remaining moisture on the cable surface, further increasing the dehydration effect on the cable surface.

[0021] In summary, the present invention has the following beneficial effects: The present invention can dehydrate the surface of a cable that has been cooled and solidified in a cooling tank. When the cable is transported, it drives the rotating roller to rotate. The rotational force of the rotating roller is transported to the rotating shaft through the drive mechanism. The first vibration mechanism and the second vibration mechanism on the rotating shaft vibrate and dehydrate the cable. As the rotating shaft rotates, the rotating shell rotates accordingly. The cable is swept by the rotating shell and begins to shake up and down continuously. When the cable comes into contact with the first and second movable blocks, the up and down movement of the cable will cause the first and second movable blocks to continuously squeeze the spring. At this time, the elasticity of the spring will increase the up and down movement frequency of the cable, thereby increasing the shaking effect of the cooling water. Through multiple vibrations and dehydration by the first and second vibration mechanisms, it is not necessary to dry the cable. The driving force of the first vibration mechanism is provided by the rotating roller, which does not require additional energy consumption. After vibration and dehydration, the cable passes through the drying mechanism, which air-dries the entire cable. Combining vibration dehydration and air-drying dehydration effectively increases the dehydration and drying effect of the cable surface. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The embodiments of the present invention will now be described.

[0031] A production line for high-temperature resistant cables for aerospace applications and its manufacturing method, such as Figure 1-6 As shown, a cooling tank 1 is included for water-cooling and curing of cables that have passed through an extruder. However, after cooling is completed, a large amount of cooling water will remain on the surface of the cable. Therefore, it is necessary to remove water from the surface of the cable. In order to achieve the above purpose, this embodiment is provided with a first vibration mechanism 7 and a second vibration mechanism 8 at the outlet end of the cooling tank 1 for vibrating and removing water from the cable. After the vibration and water removal is completed, the cable is dried by air drying mechanism 9.

[0032] The specific structure of the first vibration mechanism 7 is as follows: Figure 4As shown, it includes a fixed sleeve 701, which is disposed on the surface of the rotating shaft 12. The surface of the fixed sleeve 701 is arrayed with rotating shells 702. When the cable passes through the cooling tank 1, the cable rests on the top of the rotating shells 702. The rotating shaft 12 drives the fixed sleeve 701 to rotate, and the rotating shells 702 rotate accordingly. The rotation of the rotating shells 702 will continuously sweep the cable, causing the cable to shake up and down, shaking off the water on the surface of the cable. The surfaces of the first movable block 801 and the second movable block 802 are provided with arc-shaped fixed grooves 803. The side wall of the first movable block 801 is provided with a drain hole 804. The fixed grooves 803 provide space for the cable to shake, and the shaking and water removal effect is better. The water shaken off the cable is discharged through the drain hole 804 to prevent the cooling water from re-adheding during the shaking process.

[0033] To prevent the rotating housing 702 from damaging the cable, the first vibration mechanism 7 also includes a roller 703. The roller 703 is located on the top of the rotating housing 702, and the surface of the roller 703 protrudes from the groove of the rotating housing 702. The roller 703 can reduce the hard contact between the rotating housing 702 and the cable, thus protecting the cable.

[0034] The specific structure of the second vibration mechanism 8 is as follows: Figure 5 As shown, the mechanism includes a first movable block 801 and a second movable block 802 inserted on top of the first movable block 801. One end of each of the first and second movable blocks 801 has an elastic mechanism. The elastic mechanism includes a fixed base 805, a mounting block 806, and a spring 807. The spring 807 is located inside the fixed base 805, and one end of the spring 807 is connected to the mounting block 806. The elastic mechanism is divided into upper and lower groups, and the mounting blocks 806 of the upper and lower groups are respectively connected to the second movable block 802 and the first movable block 801. After passing through the first vibration mechanism 7, the cable enters the second vibration mechanism 8, located between the first and second movable blocks 801. As the rotating shell 702 rotates, it drives the cable to move up and down continuously. The cable also drives the first and second movable blocks 801 and 802 to continuously compress the spring 807. At this time, the elasticity of the spring 807 increases the frequency of the cable's up and down movement.

[0035] The vibration effect of the cable is enhanced by the first vibration mechanism 7 and the second vibration mechanism 8, which increases the vibration dehydration frequency of the cable and results in a better dehydration effect.

[0036] For example, the vibration dehydration of the first vibration mechanism 7 is achieved by the rotation of the rotating shaft 12. The rotation of the rotating shaft 12 can be achieved by a motor. However, in this case, a motor control system needs to be provided to control the motor, which will increase the overall dehydration cost. Therefore, if the rotational force of the cable driving the rotating roller 3 can be utilized, the dehydration cost of the cable can be effectively reduced.

[0037] One end of the rotating roller 3 is connected to a drive mechanism, including a first synchronous belt mechanism 4, a second synchronous belt mechanism 5, and a rotating shaft 12. The first synchronous belt mechanism 4 is connected to one end of the rotating roller 3 and is connected to the rotating shaft 12. There are two rotating shafts 12, and the second synchronous belt mechanism 5 is connected between the rotating shafts 12. The surface of the rotating roller 3 is provided with a groove 10. The cable passes through the groove 10 to drive the rotating roller 3 to rotate. The rotational force of the rotating roller 3 is transmitted to the rotating shaft 12 through the first synchronous belt mechanism 4, which drives the rotating shaft 12 to rotate. Multiple rotating shafts 12 are synchronously driven by the second synchronous belt mechanism 5, which does not require an additional motor drive and effectively reduces the dehydration effect of the cable.

[0038] A water collection tank 2 is provided on one side of the cooling tank 1. A fixed shell 6 is provided on the top of the water collection tank 2. Through slots 11 are provided on both sides of the fixed shell 6. The first vibration mechanism 7 and the second vibration mechanism 8 are both located inside the fixed shell 6. The water dehydrated by vibration is collected through the water collection tank 2 for subsequent discharge.

[0039] The cable passing through the first vibration mechanism 7 and the second vibration mechanism 8 needs to enter the drying mechanism 9 for air drying. The cable passes through the through groove 11 of the fixed shell 6 and enters the mounting ring 901. The mounting ring 901 is installed on one side of the water collection tank 2. The inside of the mounting ring 901 is provided with an air outlet 902. An air inlet pipe 903 is provided at the bottom of the mounting ring 901. A fan is provided at the bottom of the air inlet pipe 903. The fan supplies air to the mounting ring 901 through the air inlet pipe 903. The mounting ring 901 and the air outlet 902 are annular. The air is discharged from the air outlet 902, which can effectively blow air around the cable. Compared with the traditional direct blowing of a fan, it has a wider coverage area for the cable and a better dehydration effect.

[0040] The cable dehydration process is as follows: First, the cable is dehydrated by vibration through the first vibration mechanism 7 and the second vibration mechanism 8. After the vibration dehydration is completed, the cable enters the drying mechanism 9 for air drying.

[0041] The operation process of the high-temperature resistant cable production line for aerospace applications is as follows: First, copper monofilaments are drawn, then annealed. After annealing, the conductors are regularly twisted into cores. During the twisting process, a compaction method is used to transform ordinary round conductors into fan-shaped conductors. The twisted cores then pass through an extruder. Molten plastic inside the extruder is extruded from the die opening, wrapping around the cores to form a continuous, dense insulation layer. After extrusion, the cable needs to be cooled and solidified. The cable enters cooling tank 1 for cooling. While the cable is moving in cooling tank 1 for cooling, it drives rotating roller 3 to rotate. The rotational force of rotating roller 3 is transported to rotating shaft 12 via the first synchronous belt mechanism 4. The first vibration mechanism 7 and the second vibration mechanism 8 on rotating shaft 12 vibrate and dehydrate the cable. As rotating shaft 12 rotates, the rotating shell... 702 also rotates, and the cable is swept by the rotating housing 702, starting to shake up and down continuously. When the cable comes into contact with the first movable block 801 and the second movable block 802, the up and down movement of the cable will cause the first movable block 801 and the second movable block 802 to continuously squeeze the spring 807. At this time, the elasticity of the spring 807 will increase the up and down movement frequency of the cable, thereby increasing the shaking effect of the cable cooling water. After being dehydrated by the first vibration mechanism 7 and the second vibration mechanism 8, the cable passes through the drying mechanism 9, which further dries the cable. The fan supplies air to the mounting ring 901 through the air inlet pipe 903, and the drying air is sprayed out from the air outlet 902, which can cover the circumference of the cable and blow away the remaining moisture on the cable surface, further increasing the dehydration effect of the cable surface.
