Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal wire processing technology, and in particular to an anti-oxidation device for extruded wire. Background Technology
[0002] Extruded wire is a type of metal wire specifically designed for brazing processes. It is manufactured through an extrusion process. The process involves placing a brazing filler metal ingot into a die, then applying pressure to cause plastic deformation and extrude it through the die orifice. Because the brazing filler metal ingot is quite hard, it typically needs to be heated during the extrusion process to soften it. Extruded wire produced in this way has a high surface temperature, and if exposed to air for extended periods, an oxide layer will form on the surface. Using extruded wire with this oxide layer for brazing will result in poor weld quality and increased welding difficulty.
[0003] For extruded yarns with an existing oxide layer, the traditional method is to use acid pickling to remove the surface oxide layer. However, this method has several problems. First, because the oxide layer is relatively thick, the acid pickling process is often time-consuming, which significantly affects production efficiency and increases the wear and tear on the extruded yarns. Second, the wastewater generated during the acid pickling process must be treated before discharge, which undoubtedly increases production costs. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide an anti-oxidation device for extruded filaments, which can rapidly cool the extruded filaments and perform effective anti-oxidation treatment on them, thereby avoiding the pickling process, reducing the loss of extruded filaments, reducing production costs and improving production efficiency.
[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:
[0006] An anti-oxidation device for extruded filament includes a cooling box, a cooling plate, and a sealing cover. The cooling plate covers the cooling box, and the sealing cover is fixedly mounted on the cooling plate. An air inlet pipe is provided on the side of the cooling plate and extends to the upper surface of the cooling plate. Multiple bottom-closed wire-holding grooves are provided at intervals on the cooling plate and extend to both ends of the cooling plate, forming a wire inlet and a wire outlet on the cooling plate. A water inlet and a water outlet are provided on the side wall of the cooling box.
[0007] After the extruded yarn is produced, it is introduced into the cooling plate through the yarn inlet, and water is injected into the cooling tank located below the cooling plate through the water inlet to achieve rapid cooling of the extruded yarn. The combined design of the cooling plate and the sealing cover creates a relatively closed cooling space, which significantly reduces the chance of direct contact between external air and the cooling yarn. In addition, the air inlet pipe allows inert gases such as nitrogen to be injected above the cooling plate, effectively preventing oxidation of the yarn during cooling and ensuring the quality and performance of the yarn. This design combines water cooling with a gas anti-oxidation device, working together on the newly produced extruded yarn to help it cool rapidly and minimize contact with air, thereby avoiding oxidation. The extruded yarn treated by this device has a rapidly decreasing temperature and is less prone to oxide film formation, thus eliminating the need for subsequent pickling. This not only reduces the loss of extruded yarn and lowers production costs but also improves production efficiency.
[0008] Furthermore, the cooling plate includes a baffle and a base plate. The baffle is fixedly installed on the edge of the base plate, and the wire clamping groove is installed on the base plate. The edge of the sealing cover plate contacts the baffle and forms a gas storage chamber between the sealing cover plate and the cooling plate. The air inlet pipe connects to the gas storage chamber. The presence of the baffle creates a gas storage chamber between the sealing cover plate and the base plate, allowing inert gases such as nitrogen to be introduced into the gas storage chamber. This ensures that the extruded wire can fully contact the introduced gas, maximizing the anti-oxidation effect of the gas.
[0009] Preferably, multiple flow guide baffles are evenly spaced inside the cooling box. The left and right ends of each baffle are connected to the inner wall of the cooling box. The installation direction of the baffles is perpendicular to the slots. One end of each baffle has a flow guide hole, and the flow guide holes on adjacent baffles are not coaxial. With the flow guide baffles in the cooling box, when water is injected into the cooling box through the inlet pipe, the cooling water flows through the flow guide holes into the cavities formed by the baffles. Because the flow guide holes are not coaxial, the cooling water flows in an S-shape within the cooling box, thus improving the cooling effect.
[0010] Preferably, the inner wall of the cooling tank is provided with multiple retaining plate slots at intervals, and the flow guide baffles are fixed in the retaining plate slots. The retaining plate slot design not only fixes the flow guide baffles, but also facilitates the disassembly and assembly of the backflow baffles, thereby allowing the water flow rate to be changed according to actual needs to control the cooling speed.
[0011] Preferably, the cross-section of the wire guide groove is U-shaped, while the wire guide groove itself is S-shaped. Because extruded wire is manufactured through hot extrusion, freshly produced extruded wire is relatively soft. The U-shaped wire guide groove design allows the extruded wire to be quickly guided into the groove, facilitating rapid insertion. Furthermore, in actual production, extruded wires of different diameters are prepared, so the diameter of the wire guide groove is often designed to be slightly larger than the extruded wire. In this case, if the wire guide groove is straight, smaller-diameter extruded wires cannot make sufficient contact with the groove. However, setting the wire guide groove to S-shape ensures good contact for extruded wires of different diameters, thereby improving cooling efficiency, shortening the wire cooling time, and reducing wire oxidation.
[0012] Preferably, the water inlet is located at the end of the cooling box near the wire inlet, and the water outlet is located at the end of the cooling box near the wire exit. Both the inlet and outlet are located on the side wall of the cooling box away from the guide hole. The temperature is highest when the extruded wire enters the wire inlet. Positioning the water inlet near the wire inlet allows the cooling water to be applied immediately when the extruded wire is at its hottest, thus quickly initiating the cooling process. The water outlet is located near the wire exit, ensuring that the wire continues to receive cooling water before leaving the cooling box until the desired cooling effect is achieved. This layout optimizes the utilization of cooling water, thereby improving cooling efficiency.
[0013] Preferably, the sealing cover is provided with a sealing ring at its edge, the sealing ring having a U-shaped cross-section. This design ensures a good seal between the sealing cover and the cooling plate, helping to prevent gas leakage from the gas storage chamber, reducing gas consumption, and ensuring the continuous and effective anti-oxidation effect.
[0014] Preferably, the inner top of the cooling box has a slot, in which a sealing strip is installed. The cooling plate is mounted on the cooling box, and its bottom abuts against the sealing strip in the slot. This design significantly enhances the sealing performance between the cooling box and the cooling plate. When the cooling plate is mounted on the cooling box, its bottom abuts against the sealing strip, effectively preventing cooling water leakage from the cooling box.
[0015] Preferably, the system also includes a bracket comprising four support rods and a square support frame. The square support frame is fixedly mounted in the middle of the support rods, and the cooling box is mounted on the square support frame. The support rods have mounting slots, one end of which extends to the square support frame and the other end to the top of the support rod. The cooling box slides into the mounting slots. This bracket structure, consisting of four support rods and a square support frame, provides robust support for the cooling box. The mounting slots on the support rods, with one end extending to the square support frame and the other end to the top of the support rod, allow the cooling box to slide into the mounting slots. This simplifies the installation process and makes disassembly and replacement of the cooling box easier and faster, improving maintenance efficiency.
[0016] Preferably, the upper opening of the mounting slot is larger than the lower opening. The larger upper opening provides more space for installing the cooling box, simplifying the installation process and reducing installation difficulties caused by space constraints. The smaller lower opening helps ensure a tighter fit between the cooling box and the mounting slot after installation, reducing the possibility of loosening or shaking. Furthermore, because the sealing cover is relatively heavy, the mounting slot allows both ends of the sealing cover to rest against it when it is open, thus preventing the sealing cover from tipping over.
[0017] In summary, this extruded filament anti-oxidation device enables rapid cooling of the extruded filament and effectively resists oxidation, thereby avoiding the pickling process, reducing the loss of extruded filament, lowering production costs, and improving production efficiency.

Detailed Implementation
[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0027] In the description of this utility model, it should be understood that the orientation and positional relationship indicated by terms such as "up", "down", "left", "right", "front", "back", "vertical", "bottom", "inner", and "outer" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0028] like Figure 1 The device for preventing oxidation of extruded filaments shown includes a cooling box 1, a cooling plate 2, and a sealing cover 3. The cooling plate 2 covers the cooling box 1, and the sealing cover 3 is fixedly mounted on the cooling plate 2. An air inlet pipe 4 is provided on the side of the cooling plate 2, extending to the upper surface of the cooling plate 2. Multiple bottom-closed wire-holding grooves 21 are spaced apart on the cooling plate 2. Figure 3 As shown, the wire groove 21 extends to both ends of the cooling plate 2 and forms a wire inlet 211 and a wire outlet 212 on the cooling plate 2. The side wall of the cooling box 1 is provided with a water inlet 11 and a water outlet 12.
[0029] After the extruded yarn is produced, it is introduced into the cooling plate 2 through the yarn inlet 211, and water is injected into the cooling tank 1 located below the cooling plate 2 through the water inlet 11 to achieve rapid cooling of the extruded yarn. The combined design of the cooling plate 2 and the sealing cover plate 3 creates a relatively closed cooling space, which significantly reduces the probability of direct contact between external air and the cooling yarn. In addition, the setting of the air inlet pipe 4 allows inert gases such as nitrogen to be injected above the cooling plate 2, effectively preventing oxidation of the yarn during the cooling process and ensuring the quality and performance of the yarn. This design combines water cooling with a gas anti-oxidation device, working together on the newly produced extruded yarn to help it cool rapidly and minimize contact with air, thereby avoiding oxidation. The extruded yarn treated by this device has a rapidly decreasing temperature and is less prone to oxide film formation, thus eliminating the need for subsequent pickling treatment. This not only reduces the loss of extruded yarn and lowers production costs, but also improves production efficiency.
[0030] Furthermore, such as Figure 2 and Figure 3 As shown, the cooling plate 2 includes a baffle 22 and a base plate 23. The baffle 22 is fixedly disposed on the edge of the base plate 23. A wire retaining groove 21 is disposed on the base plate 23. The edge of the sealing cover plate 3 contacts the baffle 22 and forms a gas storage chamber 5 between the sealing cover plate 3 and the cooling plate 2. The air inlet pipe 4 connects to the gas storage chamber 5. The presence of the baffle 22 creates a gas storage chamber 5 between the sealing cover plate 3 and the base plate 23, allowing inert gases such as nitrogen to be introduced into the gas storage chamber 5. This ensures that the extruded wire can fully contact the introduced gas, maximizing the anti-oxidation effect of the gas.
[0031] As a preferred option, such as Figure 5 As shown, multiple flow guide baffles 13 are evenly spaced inside the cooling box 1. The left and right ends of the flow guide baffles 13 are connected to the inner wall of the cooling box 1. The installation direction of the flow guide baffles is perpendicular to the slot 21. One end of each flow guide baffle 13 has a flow guide hole 131, and the flow guide holes 131 on adjacent flow guide baffles 13 are not coaxial. With the flow guide baffles 13 in the cooling box 1, when water is injected into the cooling box 1 through the inlet pipe, the cooling water flows through the flow guide holes 131 step by step into the cavity formed by the flow guide baffles. Because the flow guide holes 131 are not coaxial, the cooling water flows in an S-shape within the cooling box 1, thereby improving the cooling effect.
[0032] As a preferred option, such as Figure 6 As shown, multiple baffle slots 14 are spaced apart on the inner wall of the cooling tank 1, and the flow guide baffles 13 are fixed in the baffle slots 14. The design of the baffle slots 14 not only fixes the flow guide baffles 13, but also facilitates the disassembly and assembly of the backflow baffles, so as to change the water flow rate according to actual needs to control the cooling speed.
[0033] As a preferred option, such as Figure 2 and Figure 4As shown, the cross-section of the wire-holding groove 21 is U-shaped, while the cross-section of the wire-holding groove 21 is S-shaped. Because extruded wire is manufactured through hot extrusion, freshly produced extruded wire is relatively soft. The U-shaped design of the wire-holding groove 21 allows the extruded wire to be quickly held into the groove, facilitating rapid insertion. Furthermore, in actual production, extruded wires of different diameters are often produced, so the diameter of the wire-holding groove 21 is often designed to be slightly larger than the diameter of the extruded wire. In this case, if the wire-holding groove 21 is set as a straight line, the smaller diameter of the extruded wire will not be able to fully contact the groove. Setting the wire-holding groove 21 as S-shaped ensures that extruded wires of different diameters can all make good contact with the groove, thereby improving the cooling effect, shortening the cooling time of the wire, and reducing the oxidation of the wire.
[0034] Preferably, the water inlet 11 is located on the cooling box 1 near the wire inlet 211, and the water outlet 12 is located on the cooling box 1 near the wire outlet 212. Both the water inlet 11 and the water outlet 12 are located on the side wall of the cooling box 1 away from the guide hole 131. The temperature is highest when the extruded wire enters the wire inlet 211. Positioning the water inlet 11 near the wire inlet 211 allows the cooling water to be applied immediately when the extruded wire temperature is highest, thus quickly initiating the cooling process. The water outlet 12 is located near the wire outlet 212, ensuring that the wire continues to receive cooling water before leaving the cooling box 1 until the desired cooling effect is achieved. This layout optimizes the utilization of cooling water, thereby improving cooling efficiency.
[0035] As a preferred option, such as Figure 2 and Figure 3 As shown, a sealing ring 31 is provided on the edge of the sealing cover plate 3, and the sealing ring (31) has a U-shaped cross-section. This design ensures that a good sealing effect can be formed between the sealing cover plate 3 and the cooling plate 2, which helps to prevent gas from leaking from the gas storage chamber 5, not only reducing the amount of gas used, but also ensuring the continuous and effective anti-oxidation effect.
[0036] As a preferred option, such as Figure 3 and Figure 5 As shown, a slot 15 is provided at the top inner side of the cooling box 1, and a sealing strip 151 is installed in the slot 15. The cooling plate 2 is installed on the cooling box 1, and the bottom of the cooling plate 2 presses the sealing strip 151 against the slot 15. This design significantly enhances the sealing performance between the cooling box 1 and the cooling plate 2. When the cooling plate 2 is installed on the cooling box 1, its bottom presses against the sealing strip 151, effectively preventing the leakage of cooling water in the cooling box 1.
[0037] As a preferred option, such as Figure 1As shown, the system also includes a bracket 6, which comprises four support rods 61 and a square support frame 62. The square support frame 62 is fixedly mounted in the middle of the support rods 61, and the cooling box 1 is mounted on the square support frame 62. The support rods 61 are provided with mounting grooves 611, one end of which extends to the square support frame 62, and the other end extends to the top of the support rod 61. The cooling box 1 slides into the mounting grooves 611. By introducing the bracket 6 structure consisting of four support rods 61 and a square support frame 62, a solid support is provided for the cooling box 1. The mounting grooves 611 on the support rods 61, with one end extending to the square support frame 62 and the other end extending to the top of the support rod 61, allow the cooling box 1 to slide into the mounting grooves 611. This not only simplifies the installation process of the cooling box 1 but also makes disassembly and replacement of the cooling box 1 easier and faster, improving maintenance efficiency.
[0038] Preferably, the upper opening of the mounting groove 611 is larger than the lower opening. The larger upper opening provides more space for installing the cooling box 1, simplifying the installation process and reducing installation difficulties caused by space constraints. The smaller lower opening helps ensure a tighter fit between the cooling box 1 and the mounting groove 611 after installation, reducing the possibility of loosening or shaking. Furthermore, because the sealing cover 3 is relatively heavy, the presence of the mounting groove 611 allows both ends of the sealing cover 3 to rest against it when it is open, thus preventing the sealing cover 3 from tipping over.
[0039] In summary, this extruded filament anti-oxidation device enables rapid cooling of the extruded filament and effectively resists oxidation, thereby avoiding the pickling process, reducing the loss of extruded filament, lowering production costs, and improving production efficiency.
[0040] In summary, 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 and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
