Description

Technical Field

[0001] This utility model relates to the field of titanium wire annealing technology, and in particular to a single-wire titanium wire annealing device. Background Technology

[0002] Titanium wire, a metallic material with excellent properties such as high strength, corrosion resistance, and good biocompatibility, is widely used in aerospace, medical devices, chemical industry, and sporting goods. During the production and processing of titanium wire, cold working can lead to stress concentration and lattice distortion inside the titanium wire, resulting in work hardening, which manifests as increased hardness and decreased plasticity, making it difficult to meet the requirements of subsequent forming or use. Therefore, annealing is an indispensable key process in the production of titanium wire. Through the process of heating, holding, and cooling, it can effectively eliminate internal stress in titanium wire, improve its microstructure, and regulate its mechanical properties.

[0003] Then, it is cooled at an appropriate rate. In the annealing process of titanium wire, there is a lack of good protective measures, which makes the titanium wire easy to react with oxygen when heated and at high temperature, resulting in oxidation of the titanium wire and affecting the annealing quality of the titanium wire.

[0004] The existing patent (publication number: CN217781254U) discloses an online annealing device for titanium wire processing. By setting a sealing tube, the interior of the heating furnace can be kept in a better sealed state. During the cooling process of the titanium wire, the gas inside the cooling box is extracted by using a vacuum pump to reduce the oxygen content inside the cooling box. This can prevent the titanium wire from oxidizing and ensure that the titanium wire can undergo a stable annealing process.

[0005] Existing patents offer solutions to the above problems, but after cold processing, a large amount of oil and tiny impurities remain on the surface of the titanium wire. If not effectively cleaned, the oil will carbonize and form black spots on the surface at the high temperature of annealing, while the impurities may react with the titanium wire, causing surface defects and thus reducing the surface quality and performance stability of the titanium wire.

[0006] To address this, a single-wire annealing device for titanium wire is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a titanium wire single-wire annealing device that can solve the problem that after cold working, the surface of the titanium wire will have a large amount of oil and tiny impurities. If it is not effectively cleaned, the oil will carbonize and form black spots on the surface at the high temperature of annealing, and the impurities may react with the titanium wire, resulting in surface defects, thereby reducing the surface quality and performance stability of the titanium wire.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a titanium wire single-wire annealing device, comprising a main frame, wherein a pretreatment mechanism, a heating chamber, and a cooling chamber are respectively arranged inside the main frame. The pretreatment mechanism is located on the front side inside the main frame, the heating chamber is located on the rear side of the pretreatment mechanism, and the cooling chamber is located on the rear side of the heating chamber. The pretreatment mechanism includes a cleaning component and a drying component. The cleaning component includes a cleaning tank, which is fixedly installed on the front side inside the main frame. An alcohol solution is provided inside the cleaning tank. A support roller is rotatably connected inside the cleaning tank via a bearing. Grooves are provided on the front and rear sides of the top of the cleaning tank. Two guide rollers are rotatably connected inside the grooves via bearings, and the two guide rollers are arranged symmetrically up and down. An ultrasonic generator is fixedly installed on the inner wall of the cleaning tank.

[0009] Preferably, the drying assembly includes a U-shaped frame, which is fixedly connected to the rear side of the washing tank, and a bottom roller is rotatably connected inside the U-shaped frame via a bearing.

[0010] Preferably, an mounting cavity is provided directly above the bottom roller, and a top roller is rotatably connected inside the mounting cavity via a bearing, and the top roller is used in conjunction with the bottom roller.

[0011] Preferably, a hot air blower is fixedly installed on the outside of the main frame, and a metal corrugated pipe is fixedly connected to the air outlet end of the hot air blower. The other end of the metal corrugated pipe is fixedly connected to the mounting cavity.

[0012] Preferably, an adjusting rod extends through the top of the U-shaped frame, the bottom end of the adjusting rod is fixedly connected to the top of the mounting cavity, and a fastening spring is sleeved on the surface of the adjusting rod. The two ends of the fastening spring are fixedly connected to the top of the inner wall of the U-shaped frame and the top of the mounting cavity, respectively.

[0013] Preferably, vertical grooves are provided on both sides of the inner wall of the U-shaped frame, and sliders are fixedly connected to both sides of the mounting cavity, with the sliders slidably connected inside the vertical grooves.

[0014] Preferably, a discharge pipe is fixedly connected to the bottom of the cleaning tank, and a valve is installed inside the discharge pipe.

[0015] Preferably, the support roller and guide roller are both made of ceramic material, and the bottom roller and top roller are both made of silicone material.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This application, by setting up a cleaning component, allows the alcohol solution inside the cleaning tank to dissolve the oil on the surface of the titanium wire when the titanium wire passes through it. The high-frequency vibration generated by the ultrasonic generator can cause the alcohol solution to form microbubbles. The impact force generated by the bursting of the bubbles can effectively remove stubborn oil and micro impurities, thereby improving the cleaning effect. The guide rollers arranged symmetrically at the top and bottom can limit the titanium wire and prevent it from shifting and shaking during the cleaning process. The support roller can support the titanium wire and keep it stably in the alcohol solution inside the cleaning tank, further improving the cleaning effect.

[0018] 2. This application, by setting up a drying component, with the bottom roller and top roller working together, can squeeze the surface of the titanium wire to remove some of the residual alcohol solution. The hot air generated by the hot air blower is delivered to the installation cavity through the metal corrugated pipe, which can dry the titanium wire that passes through, accelerate the evaporation of the alcohol solution, avoid the residual alcohol solution adsorbing dust and causing secondary pollution, and also prevent the impact on the temperature stability of the subsequent heating chamber.

[0025] 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.

[0026] Please see Figure 1-5 The present invention provides the following technical solution:

[0027] A titanium wire single-wire annealing device includes a main frame 1. A pretreatment mechanism 2, a heating chamber 3, and a cooling chamber 4 are respectively arranged inside the main frame 1. The pretreatment mechanism 2 is located on the front side inside the main frame 1, the heating chamber 3 is located on the rear side of the pretreatment mechanism 2, and the cooling chamber 4 is located on the rear side of the heating chamber 3. The pretreatment mechanism 2 includes a cleaning component 21 and a drying component 22. The cleaning component 21 includes a cleaning tank 211, which is fixedly installed on the front side inside the main frame 1. An alcohol solution is placed inside the cleaning tank 211. A support roller 212 is rotatably connected to the inside of the cleaning tank 211 via a bearing. Grooves 213 are provided on both the front and rear sides of the top of the cleaning tank 211. Two guide rollers 214 are rotatably connected to the inside of the grooves 213 via bearings, and the two guide rollers 214 are arranged symmetrically vertically. An ultrasonic generator 215 is fixedly installed on the inner wall of the cleaning tank 211.

[0028] In this embodiment: by setting up the cleaning component 21, the cleaning tank 211 serves as a carrier for the cleaning operation, providing a space to hold the alcohol solution and forming a relatively closed cleaning environment. This prevents the alcohol from evaporating too quickly or external impurities from falling in, ensuring a stable cleaning process. The alcohol solution, with its good fat solubility, can quickly dissolve residual drawing oil, lubricant, and other oil stains on the surface of the titanium wire, laying the foundation for subsequent ultrasonic cleaning. The support roller 212 supports the titanium wire, ensuring it is completely immersed in the alcohol solution and preventing localized non-contact due to the wire sagging or floating under its own weight. The cleaning solution ensures thorough cleaning. Two sets of guide rollers 214 clamp the titanium wire from above and below to achieve precise guidance, preventing the titanium wire from shifting or swaying during transport and ensuring that the titanium wire passes through the cleaning solution along a fixed path. This ensures uniform contact between all parts of the wire and the solution, improving cleaning consistency. The ultrasonic generator 215 is fixed to the inner wall of the cleaning tank 211. During operation, it generates high-frequency mechanical vibration, which can cause a large number of tiny bubbles to form inside the alcohol solution. When the bubbles burst violently on the surface of the titanium wire, they release impact force, which can peel off the attached stubborn oil and fine impurities, thereby improving the cleaning effect.

[0029] Specifically, such as Figure 3As shown, the drying assembly 22 includes a U-shaped frame 221, which is fixedly connected to the rear side of the washing tank 211. The bottom roller 222 is rotatably connected inside the U-shaped frame 221 via a bearing.

[0030] Specifically, such as Figure 3 As shown, an installation cavity 223 is provided directly above the bottom roller 222. The top roller 224 is rotatably connected to the inside of the installation cavity 223 through a bearing, and the top roller 224 is used in conjunction with the bottom roller 222.

[0031] Specifically, such as Figure 3 As shown, a hot air blower 225 is fixedly installed on the outside of the main frame 1. A metal corrugated pipe 226 is fixedly connected to the air outlet end of the hot air blower 225. The other end of the metal corrugated pipe 226 is fixedly connected to the mounting cavity 223.

[0032] In this embodiment: With the above configuration, the U-shaped frame 221 serves as the basic support structure for the drying assembly 22, providing a stable mounting carrier for components such as the bottom roller 222 and the mounting cavity 223. Simultaneously, its structural frame ensures that all components are arranged in an orderly manner along the titanium wire conveying direction, guaranteeing the continuous operation of the drying process. The bottom roller 222 and the top roller 224 cooperate to form a clamping structure for the titanium wire, ensuring that the titanium wire maintains a stable conveying height and path during the drying process. The mounting cavity 223 accommodates the top roller 224 and provides a relatively enclosed working space for the hot air delivered by the hot air blower 225. The top roller 224 and the bottom roller 222 can compress the titanium wire, allowing it to pass through... The hot air blower 225 removes residual alcohol solution from the surface of the titanium wire and rotates synchronously with the wire to avoid scratching it, thus enhancing the drying pretreatment effect. The hot air blower 225 generates a hot air source to provide heat for drying the titanium wire. The hot air accelerates the evaporation of residual alcohol on the surface of the titanium wire, ensuring that the titanium wire is completely dry before entering the heating chamber 3, preventing surface defects caused by residual liquid at high temperatures. The metal corrugated pipe 226 connects the outlet of the hot air blower 225 to the mounting cavity 223, serving to transport hot air. Its flexible characteristics facilitate adaptation to the internal space layout of the equipment, while also withstanding the hot air temperature, ensuring stable delivery of hot air to the mounting cavity 223, allowing the hot air to directly act on the surface of the titanium wire and improving drying efficiency.

[0033] Specifically, such as Figure 4 As shown, an adjusting rod 5 passes through the top of the U-shaped frame 221. The bottom end of the adjusting rod 5 is fixedly connected to the top of the mounting cavity 223. A fastening spring 6 is sleeved on the surface of the adjusting rod 5. The two ends of the fastening spring 6 are fixedly connected to the top of the inner wall of the U-shaped frame 221 and the top of the mounting cavity 223, respectively.

[0034] Specifically, such as Figure 4As shown, vertical grooves 7 are provided on both sides of the inner wall of the U-shaped frame 221, and sliders 8 are fixedly connected to both sides of the mounting cavity 223. The sliders 8 are slidably connected inside the vertical grooves 7.

[0035] In this embodiment: With the above settings, the adjusting rod 5 is an operating component for manually adjusting the height of the mounting cavity 223. By pulling the adjusting rod 5 up and down, the mounting cavity 223 and the top roller 224 can be directly driven to rise and fall, realizing the rapid adjustment of the distance between the top roller 224 and the bottom roller 222 to adapt to the drying requirements of titanium wires of different diameters. The operation is convenient and the adjustment accuracy is controllable. The fastening spring 6 is sleeved on the surface of the adjusting rod 5. By utilizing the elastic deformation of the fastening spring 6, a continuous downward pressure can be generated. This pressure acts on the mounting cavity 223, which can keep the top roller 224 in close contact with the surface of the titanium wire, ensuring the stability of the squeezing and dehydration effect. At the same time, it plays a buffering role in the titanium wire conveying process, avoiding excessive squeezing damage to the titanium wire by the top roller 224. The vertical groove 7 can provide a precise sliding track for the slider 8, limiting the movement direction of the mounting cavity 223 to only the vertical direction, preventing the mounting cavity 223 from horizontally shifting or rotating during the lifting and lowering process, ensuring that the top roller 224 and the bottom roller 222 always maintain vertical correspondence, ensuring stable clamping and uniform drying of the titanium wire.

[0036] Specifically, such as Figure 5 As shown, a discharge pipe 9 is fixedly connected to the bottom of the cleaning tank 211, and a valve 10 is installed inside the discharge pipe 9.

[0037] Specifically, such as Figure 2 , Figure 3 As shown, the support roller 212 and guide roller 214 are both made of ceramic material, while the bottom roller 222 and top roller 224 are both made of silicone material.

[0038] In this embodiment: With the above configuration, the discharge pipe 9 serves as the channel for discharging waste liquid from the cleaning tank 211. When the alcohol solution in the cleaning tank 211 becomes unusable due to prolonged use and excessive oil and impurity content, affecting its cleaning effect, the waste liquid can be discharged through the discharge pipe 9. This facilitates the replacement of the alcohol solution with a new one, ensuring the cleaning assembly 21 continuously and stably performs its cleaning function. The valve 10 controls the opening and closing of the discharge pipe 9. During normal cleaning operations, the valve 10 is closed to prevent alcohol solution leakage. When it is necessary to discharge waste liquid or clean the cleaning tank 211, opening the valve 10 allows the waste liquid to be discharged smoothly. The operation is simple. Convenient and effective control over the timing and amount of waste liquid discharge. The support roller 212 and guide roller 214 are made of ceramic material, which has high hardness and strong wear resistance. Long-term use will not easily cause scratches due to friction with titanium wire, effectively protecting the surface quality of titanium wire. In addition, it has good chemical stability, does not react with alcohol solution, and will not contaminate titanium wire and cleaning solution. The bottom roller 222 and top roller 224 are made of silicone material, which is soft and elastic, and can closely fit the surface of titanium wire of different diameters, enhancing the squeezing and dehydration effect, effectively removing residual alcohol solution from the surface of titanium wire, thereby improving the drying effect.

[0039] Working Principle: First, alcohol solution is injected into the cleaning tank 211 to the preset level to ensure that the titanium wire is completely submerged. Then, the coiled titanium wire is introduced from the front of the main frame 1, passing through the upper and lower ceramic guide rollers 214 of the groove 213 on the front side of the cleaning tank 211. After entering the cleaning tank 211, it is supported by the ceramic support roller 212, ensuring that the titanium wire is fully submerged in the alcohol solution. It then passes through the guide rollers 214 of the groove 213 on the rear side of the cleaning tank 211 and is then introduced between the silicone bottom roller 222 and the top roller 224 of the drying assembly 22. Finally, it passes through the heating chamber 3 and the cooling chamber 4 and connects to the rear winding device, completing the overall threading of the titanium wire. Then, the rear winding device is started, and its traction force will drive the titanium wire to move backward at a uniform speed. At this time, the ultrasonic generator 215 is started simultaneously. The high-frequency vibration generated by the ultrasonic generator 215 will cause the alcohol solution to move violently, effectively removing oil and impurities from the surface of the titanium wire. The cleaned titanium wire then enters... The drying assembly 22, with the top roller 224 under the continuous pressure of the fastening spring 6, tightly engages with the bottom roller 222 to squeeze the surface of the titanium wire, initially removing residual alcohol. Simultaneously, the hot air blower 225 is activated, and hot air is delivered to the mounting cavity 223 via the metal corrugated pipe 226, rapidly drying the titanium wire as it passes through, ensuring that the surface of the titanium wire is dry and free of droplets before entering the heating chamber 3. The dried titanium wire then enters the heating chamber 3, where it undergoes heat preservation treatment at the set annealing temperature to eliminate internal stress. Subsequently, it enters the cooling chamber 4, where it is rapidly cooled and shaped by air cooling or water cooling to ensure the stability of the titanium wire's mechanical properties. Finally, the annealed titanium wire is neatly wound into a roll by the winding device. When the alcohol solution in the cleaning tank 211 is observed to be turbid and contain excessive impurities, the equipment is shut down, the discharge pipe 9 valve 10 is opened to discharge the waste liquid, the cleaning tank 211 is cleaned, the valve 10 is closed, and a new alcohol solution is re-injected to ensure the stability of the subsequent pretreatment effect.

[0040] The above are merely preferred embodiments of the present utility model and are 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.
