Description

Technical Field

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

[0002] Titanium wire and titanium alloy wire are widely used in many fields such as aerospace, petrochemicals, medical and health care, automotive, construction, and sports and leisure products. For example, in the aerospace field, titanium wire is used to manufacture load-bearing components and springs, taking advantage of its high strength and lightweight characteristics; in the medical and health field, it can be used to manufacture medical devices, such as implantable dental crowns and skull fixation devices.

[0003] Existing titanium wire drawing devices extend the heating time of the titanium wire by installing multiple heating components, thereby heating the titanium wire to a deformable temperature. Then, a die of fixed size is used to press and lengthen the titanium wire. Finally, the titanium wire is moved and cooled by the rotation of the take-up wheel and the draw wheel, and finally wound onto the I-beam.

[0004] After the above equipment is completed, since the titanium wire needs to be heated to a very high temperature during the drawing process, the cooling efficiency of air cooling is low and it takes a long time to achieve the desired effect. Using water cooling is prone to titanium wire breakage due to improper operation, which increases production costs and time. Therefore, we propose a drawing device for titanium wire production.

[0010] Furthermore, a fan is fixedly connected to the inner wall of the baffle, a cooling box is fixedly connected to the outer wall of the base plate near the connecting frame, a pressing roller is rotatably connected to the inner wall of the cooling box, several auxiliary wheels are rotatably connected to the top outer wall of the cooling box, and an auxiliary mechanism is provided on the outer wall of the base plate.

[0011] Furthermore, the auxiliary mechanism includes a second pulley, the outer wall of the second pulley is fixedly connected to the outer wall of the gear, the inner wall of the second pulley is drivenly connected to a second belt, the outer wall of the second belt away from the second pulley is drivenly connected to a third pulley, the top outer wall of the third pulley is fixedly connected to a crown gear, and the outer wall of the crown gear is meshed with a second gear.

[0012] Furthermore, a positioning box is fixedly connected to the outer wall of the base plate on the side away from the support rod. The outer wall of the positioning box is rotatably connected to the outer wall of the second gear. A connecting ring is fixedly connected to the outer wall of the second gear.

[0013] Furthermore, the outer wall of the connecting ring is rotatably connected to the inner wall of the positioning box, and a plurality of connecting rods are rotatably connected to the outer wall of the connecting ring. A resistance wire heating block is rotatably connected to the outer wall of one end of the plurality of connecting rods away from the connecting ring. A sliding groove is provided on the inner wall of the connecting rod, and a support rod is slidably connected to the inner wall of the sliding groove. The outer wall of the support rod is rotatably connected to the outer wall of the connecting ring.

[0014] Furthermore, a plurality of hollow rods are fixedly connected to the inner wall of the positioning box on the side away from the connecting ring, and a telescopic rod is fixedly connected to the inner wall of the plurality of hollow rods. A limit roller is rotatably connected to the outer wall of the end of the telescopic rod away from the hollow rod.

[0015] Furthermore, a limiting plate is fixedly connected to the outer wall of the positioning box on the side away from gear two.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model incorporates a support plate and a cooling box. The support plate is fixed to the connecting frame at a certain outward angle, thus expanding the material wrapped around its surface and increasing the contact area with the outside. A fan accelerates the cooling of the material on the support plate surface. A pressing roller squeezes the material downwards, causing a portion of it to be immersed in the lubricant inside the cooling box. This immersion in the cooling box achieves the goal of expanding the titanium wire with the support plate and then cooling it with lubricant. This prevents the problems that arise when titanium wires need to be heated to very high temperatures during the drawing process. Air cooling is inefficient and takes a long time to achieve the desired effect, while water cooling is prone to breakage due to improper operation, increasing production costs and time.

[0018] 2. This utility model incorporates a second gear and resistance wire heating blocks. Because the resistance wire heating blocks are confined within the positioning box by the connecting rod and supported by the support rod, the rotation range of the support rod is limited. This ensures that multiple resistance wire heating blocks can always be assembled into a ring. The crown gear drives the second gear to rotate, which in turn drives the connecting ring to rotate within the positioning box, thereby causing the multiple resistance wire heating blocks to rotate. This achieves uniform rotation of the heating blocks by installing multiple resistance wire heating blocks around the device and using the crown gear to drive the second gear. It prevents the problem that the heating element can only heat a portion of the titanium wire surface, resulting in different temperature rise rates for different parts of the titanium wire. Therefore, to heat the entire titanium wire to the required temperature, the heating section needs to be extended, increasing the device installation cost.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0028] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 As shown, this utility model is a drawing device for titanium wire production, including a baffle 1, and a base plate 101 is fixedly connected to the outer wall of the baffle 1.

[0030] A conveying mechanism 2 is provided on the outer wall of the base plate 101. The conveying mechanism 2 includes a motor 201. The outer wall of the motor 201 is fixedly connected to the outer wall of the baffle 1. When the motor 201 is started, the output end of the motor 201 is fixedly connected to a connecting shaft 202 via a coupling. The outer wall of the connecting shaft 202 is rotatably connected to the outer wall of the baffle 1. A take-up wheel 203 is fixedly connected to the outer wall of the connecting shaft 202. The motor 201 drives the connecting shaft 202 to rotate, which in turn drives the take-up wheel 203 to rotate. The rotation of the take-up wheel 203 is restricted and supported by a support frame 215. The top of the base plate 101... A support frame 215 is fixedly connected to the outer wall of the unit. The outer wall of the support frame 215 is rotatably connected to the outer wall of the take-up reel 203. A pulley 204 is fixedly connected to the outer wall of the connecting shaft 202. A belt 206 is drivenly connected to the inner wall of the pulley 204. A second pulley 205 is drivenly connected to the outer wall of the belt 206 on the side away from the pulley 204. The belt 206 connects the pulley 204 and the second pulley 205. When the connecting shaft 202 drives the pulley 204 to rotate, the belt 206 drives the second pulley 205 to rotate simultaneously with the pulley 204. A crown gear 207 is fixedly connected to the outer wall of pulley 205. A gear 208 meshes with the outer wall of the crown gear 207. A connecting frame 209 is fixedly connected to the outer wall of the gear 208. The crown gear 207 is driven to rotate by the pulley 205. Because the crown gear 207 meshes with the gear 208, the crown gear 207 drives the gear 208 to rotate, which in turn drives the connecting frame 209 to rotate. Several support plates 214 are fixedly connected to the top outer wall of the connecting frame 209. Because multiple support plates 214 are connected to the outer wall of the connecting frame 209, the silk thread will be wound around the support plates 214. The outer side is opened up to increase the contact area between the titanium wire and the outside world, thereby accelerating the cooling speed. A fan 210 is fixedly connected to the inner wall of the baffle 1. A cooling box 211 is fixedly connected to the outer wall of the bottom plate 101 near the connecting frame 209. A pressing roller 212 is rotatably connected to the inner wall of the cooling box 211. Several auxiliary wheels 213 are rotatably connected to the top outer wall of the cooling box 211. The titanium wire at the top of the cooling box 211 is pressed into the interior of the cooling box 211 by the pressing roller 212, so that the titanium wire can be completely immersed in the lubricant. An auxiliary mechanism 3 is provided on the outer wall of the bottom plate 101.

[0031] Auxiliary mechanism 3 includes a second pulley 301, the outer wall of which is fixedly connected to the outer wall of gear 208. A second belt 302 is driven through the inner wall of the second pulley 301. A third pulley 303 is driven through the outer wall of the end of the second belt 302 away from the second pulley 301. The rotation of gear 208 drives the second pulley 301 to rotate, and the second belt 302 connects to the third pulley 303, thus allowing the second pulley 301 to drive the third pulley 303 to rotate. A crown gear 304 is fixedly connected to the top outer wall of the third pulley 303. Gear 305 meshes with the outer wall of crown gear 304. As crown gear 304 rotates, it is driven to rotate by the third pulley 303. Simultaneously, crown gear 304 meshes with gear 305, causing crown gear 304 to drive gear 305 to rotate. A positioning box 306 is fixedly connected to the outer wall of the base plate 101 on the side away from the support rod 314. The outer wall of positioning box 306 is rotatably connected to the outer wall of gear 305. A connecting ring 307 is fixedly connected to the outer wall of gear 305. The outer wall of connecting ring 307 is rotatably connected to the inner wall of positioning box 306. Gear 305 then rotates within positioning box 306. The outer rotation drives the connecting ring 307 to rotate inside the positioning box 306. Several connecting rods 315 are rotatably connected to the outer wall of the connecting ring 307. A resistance wire heating block 317 is rotatably connected to the outer wall of one end of each connecting rod 315 away from the connecting ring 307. Model: Nickel-chromium alloy resistance wire heating block Cr20Ni80; Function: Excellent high-temperature resistance, capable of long-term operation at high temperatures, suitable for applications requiring heating titanium wire to high temperatures for drawing and other processing. Strong oxidation resistance, not easily oxidized in high-temperature environments, extending the service life of the heating block. (The connection is made via the connecting rods.) 315 lifts up the resistance wire heating block 317, and multiple resistance wire heating blocks 317 fit together to form a ring, thereby quickly heating the titanium wire that passes through. The inner wall of the connecting rod 315 has a groove 316, and the inner wall of the groove 316 is slidably connected to the support rod 314. The outer wall of the support rod 314 is rotatably connected to the outer wall of the connecting ring 307. The support rod 314 rotates around the connecting ring 307, and the other end of the support rod 314 slides along the groove 316 inside the connecting rod 315, thereby ensuring that the connecting rod 315 can rotate within a small range when the diameter of the titanium wire is large.

[0032] A plurality of hollow rods 318 are fixedly connected to the inner wall of the positioning box 306 on the side away from the connecting ring 307. A telescopic rod 319 is fixedly connected to the inner wall of the hollow rods 318. A limiting roller 321 is rotatably connected to the outer wall of the end of the telescopic rod 319 away from the hollow rods 318. The limiting roller 321 supports the heated titanium wire, preventing it from bending due to gravity because the titanium wire is easily deformed after heating. The outer wall of the limiting roller 321 is slidably connected to the outer wall of the telescopic rod 319. A spring 320 is fixedly connected to the inner wall of the telescopic rod 319. A limiting plate 308 is fixedly connected to the outer wall of the positioning box 306 on the side away from the gear 305. The outer wall of the limiting plate 308... A threaded rod 309 is rotatably connected, and a knob 310 is rotatably connected to the top outer wall of the threaded rod 309. A limiting pressure plate 311 is threadedly connected to the outer wall of the threaded rod 309. By turning the knob 310, the threaded rod 309 is rotated and the limiting pressure plate 311 is pushed downward to slide. A sliding rod 312 is fixedly connected to the outer wall of the limiting plate 308 away from the threaded rod 309. The outer wall of the sliding rod 312 is slidably connected to the inner wall of the limiting pressure plate 311. The sliding process of the limiting pressure plate 311 is stabilized by the sliding rod 312. A pin 313 is inserted into the inner wall of the limiting pressure plate 311. The outer wall of the pin 313 is engaged with the inner wall of the sliding rod 312. The limiting pressure plate 311 is locked by inserting the pin 313.

[0033] One specific application of this embodiment is:

[0034] When the operator needs to use the equipment, they pull the material to be processed and fix one end onto the surface of the take-up reel 203. Then, they start the motor 201 to drive the connecting shaft 202 to rotate, which in turn drives the take-up reel 203 to rotate, thus continuously pulling the material to wind it onto the surface of the take-up reel 203. During the rotation of the connecting shaft 202, the pulley 204 will rotate, and the belt 206 connects the pulley 204 and the second pulley 205. Thus, when the pulley 204 rotates, the belt 206 drives the second pulley 205 to rotate simultaneously, which in turn drives the crown gear 207 to rotate. Since the crown gear 207 meshes with the gear 208, the crown gear 207 drives the gear 208. Gear 208 rotates. Because gear 208 is larger than crown gear 207, its rotational speed is lower than that of crown gear 207. Gear 208 drives connecting frame 209 to rotate, which in turn activates the resistance wire heating block 317 inside positioning box 306 to begin heating. Multiple resistance wire heating blocks 317 are stacked together to form a suitably sized ring that completely surrounds the material, ensuring that the material passing through is heated evenly. Since the resistance wire heating blocks 317 are confined inside positioning box 306 by connecting rod 315 and fixed by support rod 314, the rotation range of support rod 314 is limited, thus ensuring that multiple resistance wire heating blocks 317 can always be combined. Forming a ring, if the diameter of the material is too large, it will squeeze multiple resistance wire heating blocks 317 to slide outward, thereby pushing the connecting rod 315 to rotate. At the same time, one end of the support rod 314 will slide along the sliding groove 316 inside the connecting rod 315, and the other end will rotate around the connecting ring 307, so that the connecting rod 315 will still support the connecting rod 315 after rotating at a certain angle, thus ensuring that the multiple resistance wire heating blocks 317 will not separate. During the rotation of gear 208, it will drive the second pulley 301 to rotate, and because of the connection of belt two 302, it will drive the third pulley 303 to rotate at the same time, and the third pulley 303 will drive the crown gear two 304 to rotate. Since the crown gear two 304 meshes with gear two 305, This causes the crown gear 304 to drive the gear 305 to rotate, which in turn drives the connecting ring 307 to rotate within the positioning box 306. This, in turn, causes multiple resistance wire heating blocks 317 to rotate, ensuring uniform heating of the material. On the other side of the positioning box 306, multiple limiting rollers 321 are provided, and multiple telescopic rods 319 lift the limiting rollers 321. Springs 320 are connected inside the telescopic rods 319. The elasticity of the springs 320 ensures that the telescopic rods 319 are always lifted, preventing compression. Therefore, the telescopic rods 319 can be used to limit the position of the limiting rollers 321 and allow two limiting rollers 321 to move closer together. Furthermore, because the limiting rollers 321 are funnel-shaped...Therefore, after the two limiting rollers 321 are engaged, a cavity is left in the middle to accommodate the material's movement. When the material is too large, it pushes the limiting rollers 321 to compress the spring 320 inside the telescopic rod 319. The elasticity of the spring 320 pushes the telescopic rod 319, causing the limiting rollers 321 to clamp the material, thus compressing it and shortening its diameter. Then, turning the knob 310 drives the threaded rod 309 to rotate, which in turn pushes the limiting pressure plate 311 downward. The other end of the limiting pressure plate 311 slides along the slide rod 312, stabilizing its movement and preventing it from wobbling. At the same time, the limiting pressure plate 311 and the limiting plate 308 overlap, and their shapes form a circular cavity. The material is compressed and elongated through this cavity, and then the support plate... Support plate 214 is fixed to connecting frame 209 at a certain outward angle, thereby spreading the material wrapped around its surface and increasing the contact area with the outside. Fan 210 accelerates the cooling of the material on the surface of support plate 214. The cooled material is then fed into the auxiliary wheel 213 on the outside of cooling box 211 by the rotation of connecting frame 209. Pressing roller 212 compresses the material downwards, preventing it from passing over cooling box 211. Instead, a portion of the material is immersed in the lubricant inside cooling box 211. The auxiliary wheel 213 lifts the material and assists in its transmission, preventing breakage due to excessive bending angle. Finally, the continuous rotation of winding wheel 203 winds the drawn material onto its surface.
