Description

Technical Field

[0001] This utility model relates to the field of titanium wire processing technology, and in particular to a titanium wire roller drawing device. Background Technology

[0002] Titanium and titanium alloy wires are widely used in high-end fields such as aerospace, medical devices, chemical industry, and sports equipment due to their high strength, low density, excellent corrosion resistance and biocompatibility. As downstream industries continue to increase their requirements for the precision, surface quality and mechanical properties of titanium wires, the performance of their processing equipment has become a key factor affecting the quality of titanium wires.

[0003] Currently, titanium wire processing mostly employs roller die drawing technology, which uses paired rollers to extrude and shape the titanium wire blank to reduce its diameter. However, existing roller die drawing equipment still has the following problems in practical applications: On the one hand, during the drawing process, titanium wire generates metal debris due to roller friction, and drawing lubricant remains on the surface. If not cleaned in time, this will lead to contamination and scratches on the surface of the titanium wire during subsequent winding, affecting product precision. On the other hand, traditional cleaning methods are mostly offline cleaning or simple wiping, which are not only inefficient but also difficult to completely remove fine impurities and water stains adhering to the surface. Especially for fine-diameter titanium wire, residual moisture can easily cause local oxidation, damaging its surface properties.

[0004] Therefore, a titanium wire roller drawing device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a titanium wire roller drawing device that can solve the problems of existing roller drawing devices generating metal debris due to roller friction during the drawing process, and leaving drawing lubricant residue on the surface. If not cleaned in time, this will lead to contamination and scratches on the titanium wire surface during subsequent winding, affecting product precision. Furthermore, traditional cleaning methods are mostly offline cleaning or simple wiping, which are not only inefficient but also difficult to completely remove the fine impurities and water stains attached to the surface. Especially for fine-diameter titanium wires, residual moisture can easily cause local oxidation, damaging their surface properties.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a titanium wire roller drawing device, comprising a frame, a plurality of guide rollers arranged on the front side inside the frame, two rollers arranged in the middle inside the frame, and extrusion grooves formed on the surface of both rollers, a cleaning mechanism arranged on the rear side inside the frame, the cleaning mechanism comprising a chip removal component and a drying component, the chip removal component comprising a cleaning tank, the cleaning tank being fixedly installed on the rear side inside the frame, the cleaning tank containing cleaning fluid and an ultrasonic generator fixedly installed on the inner wall of the cleaning tank, guide rollers being rotatably connected inside the cleaning tank via bearings, the number of guide rollers being set to a plurality and evenly distributed in parallel, an installation hole being formed on the front side of the cleaning tank, and two limiting rollers being rotatably connected inside the installation hole via bearings, the two limiting rollers being arranged symmetrically up and down.

[0007] Preferably, the drying assembly includes a fixing frame, which is fixedly connected to the rear side of the top of the cleaning tank. Vertical grooves are provided on both sides of the inner wall of the fixing frame. A bidirectional screw is rotatably connected to the inside of the left vertical groove through a bearing, and a sliding rod is fixedly connected to the inside of the right vertical groove.

[0008] Preferably, both ends of the surface of the bidirectional screw are threaded with screw blocks, both ends of the surface of the slide bar are slidably connected with sliders, and an installation frame is fixedly connected between the opposite sides of the screw blocks and the sliders, with the two installation frames arranged symmetrically from top to bottom, and a rubber plate is embedded in the front side of the installation frame.

[0009] Preferably, a drive motor is fixedly installed on the left side of the top of the fixed frame, and the output shaft of the drive motor is fixedly connected to the top end of the bidirectional screw.

[0010] Preferably, a heat outlet cavity is fixedly connected to the rear side of the mounting frame, and multiple heat outlet holes are opened on the opposite side of the two heat outlet cavities.

[0011] Preferably, a Y-shaped corrugated pipe is fixedly connected to the inside of the heat outlet cavity, and the other end of the Y-shaped corrugated pipe passes through the fixed frame and is fixedly connected to the external hot air generator.

[0012] Preferably, a drain pipe is fixedly connected to the bottom of the cleaning tank, and a valve is installed inside the drain pipe.

[0013] Preferably, the front and rear sides of the equipment frame are respectively provided with an unwinding device and a winding device, and the unwinding device, rollers, cleaning mechanism and winding device are used in cooperation with each other.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting up a chip removal component, the cleaning fluid in the cleaning tank can initially dissolve the lubricant remaining on the surface of the titanium wire, while the high-frequency vibration generated by the ultrasonic generator can completely peel off the metal chips and fine impurities attached to the surface of the titanium wire, ensuring that there are no dead corners in the cleaning of impurities. The setting of multiple guide rollers can guide the titanium wire to travel smoothly in the cleaning fluid, extend the cleaning time, and improve the cleaning effect, thereby effectively solving the problems of low efficiency and incomplete cleaning of traditional offline cleaning or simple wiping. 2. This application, by setting up a drying component, allows the spacing between the two mounting frames to be adjusted through the cooperation of the screw block and the slider, so that the rubber plate can be tightly attached to the surface of titanium wires of different diameters. The squeezing action removes most of the water stains on the surface of the titanium wires. At the same time, the external hot air generator sends hot air into the heat outlet chamber through the Y-shaped corrugated pipe, so that the hot air is evenly blown onto the titanium wires through the heat outlet holes, which can dry the residual moisture. This dual drying method of squeezing out water first and then drying with hot air not only has high drying efficiency, but also avoids oxidation of the titanium wires due to residual moisture, ensuring the stability of the surface performance of the titanium wires. It solves the problems of secondary pollution and uneven drying caused by the separation of cleaning and drying links in existing equipment. Attached Figure Description

[0017] 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.

[0018] Please see Figure 1-5 The present invention provides the following technical solution: A titanium wire roller drawing device includes a frame 1. Multiple guide rollers 2 are arranged on the front side of the frame 1. Two rollers 3 are arranged in the middle of the frame 1, and each roller 3 has an extrusion groove 4 on its surface. A cleaning mechanism 5 is arranged on the rear side of the frame 1. The cleaning mechanism 5 includes a chip removal component 51 and a drying component 52. The chip removal component 51 includes a cleaning tank 511, which is fixedly installed on the rear side of the frame 1. The cleaning tank 511 contains cleaning fluid, and an ultrasonic generator 512 is fixedly installed on its inner wall. Guide rollers 513 are rotatably connected to the inside of the cleaning tank 511 via bearings. The number of guide rollers 513 is set to multiple and they are evenly distributed in parallel. A mounting hole 514 is provided on the front side of the cleaning tank 511. Two limiting rollers 515 are rotatably connected to the inside of the mounting hole 514 via bearings, and the two limiting rollers 515 are arranged symmetrically vertically.

[0019] In this embodiment: by setting up the chip removal component 51, the cleaning tank 511 can provide a closed cleaning space for the titanium wire. The cleaning fluid inside can initially dissolve the residual drawing lubricant on the surface of the titanium wire. The ultrasonic generator 512 is installed on the inner wall of the cleaning tank 511. When working, it can generate high-frequency mechanical vibration, causing the cleaning fluid to form a large number of micro bubbles. The bubbles are rapidly generated and burst near the surface of the titanium wire, generating strong impact force and micro jets, which can penetrate into the fine pits and gaps on the surface of the titanium wire, thoroughly removing the attached metal debris, oxide scale and other stubborn impurities, solving the micro-contamination problem that is difficult to handle by traditional cleaning methods. Multiple guide rollers 513 are evenly distributed in parallel, which can form the passage path of the titanium wire. Their function is to guide the titanium wire to move steadily and at a uniform speed in the cleaning fluid, while extending the soaking time of the titanium wire in the cleaning fluid, ensuring that the impurities are fully dissolved and removed, and improving the cleaning effect. The function of the limiting roller 515 is to accurately position the titanium wire, limit the lateral deviation of the titanium wire, and ensure that the titanium wire enters the cleaning area along the preset path, avoiding uneven cleaning or damage from friction with other components caused by the shaking of the titanium wire.

[0020] Specifically, such as Figure 4As shown, the drying assembly 52 includes a fixing frame 521, which is fixedly connected to the rear side of the top of the cleaning tank 511. Vertical grooves 522 are provided on both sides of the inner wall of the fixing frame 521. A bidirectional screw 523 is rotatably connected to the inside of the left vertical groove 522 through a bearing, and a slide rod 524 is fixedly connected to the inside of the right vertical groove 522.

[0021] Specifically, such as Figure 4 As shown, both ends of the surface of the bidirectional screw 523 are threaded with screw blocks 525, and both ends of the surface of the slide bar 524 are slidably connected with sliders 526. A mounting frame 527 is fixedly connected between the opposite sides of the screw blocks 525 and the sliders 526, and the two mounting frames 527 are arranged symmetrically up and down. A rubber plate 528 is embedded in the front side of the mounting frame 527.

[0022] Specifically, such as Figure 2 , Figure 4 As shown, a drive motor 6 is fixedly installed on the top left side of the fixed frame 521, and the output shaft of the drive motor 6 is fixedly connected to the top end of the bidirectional screw 523.

[0023] In this embodiment: by setting the drying component 52, the fixing frame 521 can provide stable support for components such as the bidirectional screw 523, the slide bar 524, and the mounting frame 527, while forming a relatively enclosed drying space. The bidirectional screw 523 is rotatably connected to the left vertical groove 522 through bearings. The threads at both ends of its surface are in opposite directions. Together with the slide bar 524 in the right vertical groove 522, it can form a guide structure. When the bidirectional screw 523 rotates, it can drive the screw blocks 525 at both ends to move synchronously in opposite directions. The slide bar 524 guides and limits the slider 526, ensuring that the two mounting frames 527 always maintain symmetrical movement, accurately adjusting the fit with the titanium wire, and adapting to different... To meet the drying requirements of titanium wire of different diameters, the mounting frame 527 provides a mounting carrier for the rubber plate 528. The symmetrically arranged mounting frames 527 form a clamping structure for the titanium wire. The rubber plate 528 has good elasticity and sealing properties, which can closely fit the surface of the titanium wire. It removes a large amount of water stains remaining after cleaning by squeezing, while avoiding scratching the titanium wire, laying the foundation for subsequent hot air drying. The drive motor 6 serves as the power source, and its output shaft is fixedly connected to the top of the bidirectional screw 523. By driving the bidirectional screw 523 to rotate, the distance between the two mounting frames 527 can be automatically adjusted without manual operation, improving the automation level of the equipment and adapting to the rapid switching of titanium wires of different specifications.

[0024] Specifically, such as Figure 5 As shown, a heat outlet cavity 7 is fixedly connected to the rear side of the mounting frame 527, and multiple heat outlet holes 8 are opened on the opposite side of the two heat outlet cavities 7.

[0025] Specifically, such as Figure 5As shown, a Y-shaped corrugated pipe 9 is fixedly connected inside the heat outlet cavity 7, and the other end of the Y-shaped corrugated pipe 9 passes through the fixed frame 521 and is fixedly connected to the external hot air generator.

[0026] In this embodiment: With the above settings, the heat outlet chamber 7 is fixed to the rear side of the mounting frame 527 and serves as a temporary storage and distribution component for hot air. It can form a closed cavity inside, ensuring that the hot air input from the Y-shaped corrugated pipe 9 gathers here and forms a stable airflow. The multiple heat outlet holes 8 opened on opposite sides of the two heat outlet chambers 7 can be evenly distributed according to the titanium wire's travel path, accurately guiding the hot air to the surface of the titanium wire. This design allows the hot air to fully cover the upper, lower, and surrounding areas of the titanium wire, avoiding drying dead zones and ensuring that the trace amounts of residual moisture after cleaning are thoroughly dried, preventing the titanium wire from oxidizing due to localized dampness. The Y-shaped corrugated pipe 9 is a key channel for hot air transmission. One end of the Y-shaped corrugated pipe 9 is connected to the external hot air generator, and the other end branches and is fixedly connected to the two heat outlet chambers 7 respectively, allowing the external hot air generator to supply air to the two heat outlet chambers 7 through a single path, reducing pipe interfaces, lowering the risk of hot air leakage, improving heat utilization efficiency, and ensuring the continuous and stable operation of the drying component 52.

[0027] Specifically, such as Figure 5 As shown, a drain pipe 10 is fixedly connected to the bottom of the cleaning tank 511, and a valve 11 is installed inside the drain pipe 10.

[0028] Specifically, such as Figure 5 As shown, the front and rear sides of the equipment frame 1 are respectively equipped with an unwinding device and a winding device, and the unwinding device, roller 3, cleaning mechanism 5 and winding device are used in cooperation with each other.

[0029] In this embodiment: With the above configuration, the drain pipe 10 is a dedicated channel for the discharge of cleaning fluid. During long-term operation of the equipment, the cleaning fluid in the cleaning tank 511 will gradually become ineffective due to the adsorption of a large amount of metal debris and residual lubricant. At this time, the dirty cleaning fluid can be discharged in time through the drain pipe 10, facilitating the replacement of new cleaning fluid and ensuring the subsequent cleaning effect. The valve 11 inside the drain pipe 10 plays a role in controlling the on / off state. It is normally closed to ensure that the cleaning fluid in the cleaning tank 511 maintains a certain level to meet the cleaning requirements of titanium wire. It is opened when drainage or replacement of cleaning fluid is needed, allowing flexible control of the drainage timing and discharge volume, preventing leakage of cleaning fluid when not needed, and facilitating the emptying of the cleaning tank 511 during equipment maintenance. The unwinding device is used for unwinding... The device places the coarse titanium wire blank roll to be processed. By stably releasing the blank, it provides a continuous supply of raw materials for the entire drawing process. At the same time, the guide roller 2 ensures that the blank enters the processing area of ​​the roller 3 in a stable posture, avoiding the blank from loosening or shifting and affecting the drawing accuracy. The winding device is located on the rear side of the equipment frame 1 and can form a complete production closed loop with the unwinding device, roller 3, and cleaning mechanism 5. It can neatly wind the finished titanium wire after drawing, cleaning, and drying onto the winding reel, which is convenient for subsequent storage, transportation, and use. Through the coordinated cooperation of the unwinding device, roller 3, cleaning mechanism 5, and winding device, continuous processing of titanium wire from coarse blank to finished product can be realized, which greatly improves production efficiency and ensures the stability and consistency of the titanium wire processing process.

[0030] Working principle: First, the coarse titanium wire blank roll is installed on the unwinding device at the front of the equipment frame 1. The front end of the blank is pulled through multiple guide rollers 2 in sequence, and then introduced between two rollers 3 in the middle of the equipment frame 1 to ensure that the blank is in contact with the extrusion groove 4. Then, the titanium wire that has undergone preliminary shaping by drawing is pulled through two limiting rollers 515 at the front of the cleaning tank 511, enters the cleaning tank 511 and passes around multiple guide rollers 513 in sequence, and finally passes between two rubber plates 528 of the drying component 52, connecting to the winding device at the rear of the equipment frame 1. Then, according to the diameter of the target titanium wire, the speed and pressure of the rollers 3 are adjusted by the equipment control system. Then, the drive motor 6 is started, and the distance between the two mounting frames 527 in the drying component 52 is adjusted by the bidirectional screw 523 to make the rubber plates 528 fit tightly with the surface of the titanium wire. Then, the power and working frequency of the ultrasonic generator 512 are set, and the external hot air generator is turned on, so that the external hot air generator delivers hot air to the heat outlet chamber 7 through the Y-shaped corrugated pipe 9. Then, the unwinding device and rollers are turned on simultaneously. The drive system and winding device of roller 3 cause the coarse titanium wire blank to enter the processing area of ​​roller 3 under traction. The two rollers 3 rotate relative to each other, and radial pressure is applied to the blank through the extrusion groove 4. Combined with the traction force, plastic deformation is achieved, drawing the coarse titanium wire into a fine titanium wire of the target diameter. The drawn titanium wire enters the cleaning tank 511 and travels at a constant speed in the cleaning liquid under the guidance of the guide roller 513. The ultrasonic generator 512 works to generate high-frequency vibration, and the impact force of the bursting bubbles in the cleaning liquid peels off the metal debris and residue on the surface of the titanium wire. After cleaning, the titanium wire, which retains lubricant and other impurities, is led out from the cleaning box 511. It first passes between two rubber plates 528, which remove most of the water stains on the surface of the titanium wire. Then it enters between two heating chambers 7. The hot air generated by the external hot air generator is blown evenly onto the surface of the titanium wire through the heating holes 8 to dry the residual moisture and complete the drying process. Finally, the dried titanium wire is pulled to the winding device at the rear of the equipment frame 1 and neatly wound onto the winding reel under the action of the automatic winding mechanism to form a finished titanium wire roll.

[0031] It should be noted that the specific structures, working principles, and usage methods of the unwinding and rewinding devices involved in this application are all existing technologies, and therefore are not described in detail in the text.

[0032] 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.
