Description

Technical Field

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

[0002] Currently, metal wire drawing is a common metal processing technique widely used in industries such as wire and cable, and metal products. During the wire drawing process, the metal wire needs to be lubricated with graphite emulsion beforehand, preheated, and then stretched through a die to reduce its diameter and increase its length. To achieve this, existing traditional lubrication methods include directly applying graphite emulsion or using a separate heating device or additional heating equipment to preheat the metal wire.

[0003] Related technology can be found in Chinese Patent No. CN117244954B, which discloses a multi-die hot wire drawing machine. This invention includes a machine body, a rotating wheel assembly, a heating assembly, a lubrication assembly, and a die assembly. The rotating wheel assembly includes a passive wheel and a driving wheel rotatably connected to the machine body. The passive wheel comprises several wheels with the same outer diameter, each capable of rotating relatively independently. The driving wheel is a three-stage tower wheel, with each stage independently controlled by a motor. Each stage tower wheel has 2-4 wire die tracks. The die assembly includes a mounting die frame and a wire drawing die disposed between the heating box and the driving wheel. This driving wheel structure, due to the wider outer diameter of each stage tower wheel, is suitable for high-precision polishing and has a longer friction life compared to flat wheels or tower wheels. Furthermore, because the speed of each stage tower wheel is independently adjustable, one die has relatively no slippage while the other dies experience only minor slippage on the plane of each stage tower wheel, thus reducing wear on the driving wheel and decreasing the wire breakage rate to a certain extent.

[0004] Regarding the aforementioned technologies, the device lubricates and heats the metal wire before drawing it. After drawing, lubricating oil remains on the surface of the metal wire, which contaminates the drawn metal and affects the quality of the drawn metal wire. Utility Model Content

[0005] To improve the quality of metal wire drawing, this application provides a metal wire drawing preheating device.

[0006] This application provides a metal wire drawing preheating device, which adopts the following technical solution: A metal wire drawing preheating device includes a frame, with a lubricating component, a preheating component, a forming die, and a traction component sequentially arranged above the frame. The traction component drives a metal wire to pass sequentially through the lubricating component, the preheating component, and the forming die. The lubricating component coats the outside of the metal wire with lubricating oil. The preheating component heats the lubricated metal wire. The lubricated metal wire passes through the preheating component for preheating, and after preheating, it passes through the forming die to complete the wire drawing process. The metal preheating and drawing device also includes a cleaning cylinder, which is fixed to the upper end of the frame. Located on the side of the forming mold away from the lubricating component, the metal wire passes through the forming mold and enters the cleaning cylinder, penetrating the entire cylinder. Several water spray heads are fixed circumferentially on the inner wall of the cleaning cylinder. The frame is equipped with a water supply component for supplying cleaning fluid to the water spray heads. The metal wire is located in the middle of all the water spray heads, and the cleaning fluid is sprayed from the water spray heads onto the metal wire. A recovery pipe is connected to the lower end of the cleaning cylinder, which is used to recover the cleaning fluid in the cleaning cylinder. A water suction part is provided on the side of the cleaning cylinder away from the forming mold, which is used to clean the cleaning fluid on the outer surface of the metal wire.

[0007] By adopting the above technical solution, the frame supports all components. The metal wire enters the lubrication unit under the pull of the traction component. The lubrication unit coats the surface of the metal wire with lubricating oil. After lubrication, the metal wire enters the preheating unit for preheating. Then, the metal wire enters the forming die for wire drawing. After the metal wire is drawn to the required diameter, there is residual lubricating oil on the surface of the metal wire. The metal wire passes through the through hole into the cleaning cylinder. The water supply unit delivers cleaning fluid to the cleaning cylinder to the spray head. All spray heads spray cleaning fluid onto the metal wire. The cleaning fluid washes away the lubricating oil on the surface of the metal wire. The used cleaning fluid is transported to the water supply unit for recycling through the recovery pipe. The metal wire enters the absorption unit, where the absorption unit absorbs the cleaning fluid on the surface of the metal wire, which helps to improve the quality of the metal wire.

[0008] Optionally, a filter cylinder is fixedly provided on the side of the cleaning cylinder near the forming mold. Several clamping plates are fixedly provided circumferentially on the inner wall of the filter cylinder. The clamping plates are made of elastic material and extend in the direction of the filter cylinder axis. A gap is left between all the clamping plates for the metal wire to pass through. The metal wire passes through the gap and contacts all the clamping plates.

[0009] By adopting the above technical solution, the metal wire comes into contact with all the clamps during the process of passing through the filter cylinder. During this process, the clamps scrape off the residual lubricating oil on the metal wire. Furthermore, since the clamps are made of elastic material, it helps to reduce the probability of damage to the metal wire during the cleaning process.

[0010] Optionally, an oil outlet pipe is connected to the bottom of the filter cylinder, and a filter screen is provided at the connection between the oil outlet pipe and the filter cylinder. The end of the oil outlet pipe away from the filter cylinder is connected to an oil storage tank, which is detachable.

[0011] By adopting the above technical solution, the lubricating oil remaining on the metal wire flows to the bottom of the filter cylinder through the card plate under the action of gravity. After being filtered by the filter screen, the lubricating oil is transported to the oil storage tank through the oil outlet pipe for storage. The oil storage tank is a detachable device. When the lubricating oil in the oil storage tank reaches a certain amount, the lubricating oil in the oil storage tank can be poured into the lubricating parts to realize the recycling of lubricating oil and improve the utilization rate of lubricating oil.

[0012] Optionally, baffles are provided on both sides of the cleaning cylinder. The baffles are conical in shape, and their cross-section gradually decreases in the direction away from the cleaning cylinder. The baffles have through holes in the transverse direction, through which metal wires pass.

[0013] By adopting the above technical solution, when the water spray head in the cleaning cylinder sprays cleaning fluid onto the metal wire, the baffle prevents the sprayed cleaning fluid from entering the filter cylinder, thus avoiding contamination of the lubricating oil to be recovered and also preventing a large amount of cleaning fluid from being sprayed outside the cleaning cylinder, causing waste.

[0014] Optionally, the absorbent part includes an inner disc, an outer disc, a first sponge ring, and a second sponge ring. The outer disc is sleeved on the outside of the inner disc. Both the inner and outer discs are rotatably connected to the frame. The second sponge ring is coaxially fixed on the side of the inner disc near the cleaning cylinder, and the third sponge ring is coaxially fixed on the side of the outer disc near the cleaning cylinder. A metal wire passes between the first and second sponge rings and adheres to the sponge.

[0015] By adopting the above technical solution, the inner disc supports the first sponge ring, and the outer disc supports the second sponge ring. When the metal wire passes between the first and second sponge rings, it adheres to the sponge. The moisture on the metal wire is absorbed by the sponge, which helps to reduce the probability of residual cleaning liquid contaminating the metal wire.

[0016] Optionally, the frame is provided with several support rods and a power component. The support rods are arranged circumferentially along the inner plate and are rotatably connected to the inner and outer pulleys. All the inner pulleys are located inside the inner plate and are rotatably connected to the inner plate circumferentially. The inner plate is provided with an annular groove I for accommodating the inner pulleys. All the outer pulleys are located inside the outer plate and are rotatably connected to the outer plate circumferentially. The outer plate is provided with an annular groove II for accommodating the outer pulleys. The power component is used to drive any one of the inner and outer pulleys to rotate.

[0017] By adopting the above technical solution, an inner pulley can be placed in the annular groove one on the inner side of the inner disc, and an outer pulley can be placed in the annular groove two on the inner side of the outer disc. The inner pulley applies tension to the inner wall of the annular groove one, supporting the inner disc. The outer pulley applies tension to the inner wall of the annular groove two, supporting the outer disc. The inner pulley drives the inner disc to rotate, and the outer pulley drives the outer disc to rotate. The sponge rings rotate together with the inner disc and the sponge ring two rotate together with the outer disc. The metal wire can pass through different positions between the sponge ring one and the sponge ring two. After absorbing water at any point, the sponge ring one and the sponge ring two change their contact position with the metal wire by rotating, allowing the metal wire to absorb water again, thus improving the absorption efficiency of the sponge rings.

[0018] Optionally, the power component includes a motor, a pulley assembly, and a gear set. The motor output shaft is coaxially fixed to the pulley assembly. The pulley assembly is used to connect the motor to any inner pulley and outer pulley. The gear set is located between the inner pulley and the outer pulley to achieve a rolling connection between the inner pulley and the outer pulley.

[0019] By adopting the above technical solution, the pulley group rotatably connects the motor and any pulley, the motor drives any pulley to rotate, the gear group connects the inner pulley and the outer pulley, and the gear group pushes another pulley on the same rod to rotate in the opposite direction under the drive of any pulley. The inner and outer discs then rotate in opposite directions, so the first and second sponge rings rotate in opposite directions to wipe the metal wire, thereby improving the wiping efficiency of the first and second sponge rings and the quality of the metal wire.

[0020] Optionally, the inner disc is provided with an upper column and a lower column on the side near the cleaning cylinder. The frame is fixedly connected to a rotating shaft. The upper column and the lower column are both sleeved on the outside of the rotating shaft and rotatably connected to the rotating shaft. The upper column is in close contact with the first sponge ring, and the lower column is in close contact with the second sponge ring.

[0021] By adopting the above technical solution, the upper and lower columns can rotate coaxially, and the inner and outer discs rotate under the drive of the motor. The first sponge ring contacts the upper column and rubs against it. The upper column is subjected to frictional force and rotates in the same direction as the sponge ring. The second sponge ring rubs against the lower column. The lower column is subjected to frictional force and rotates in the same direction as the second sponge ring. The upper column squeezes the first sponge ring to squeeze out water, and the lower column squeezes the second sponge ring to squeeze out water, which helps to improve the water absorption effect of the first and second sponge rings.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. Under the pull of the traction component, the metal wire sequentially enters the lubrication component for lubrication, the preheating component for heating, and the forming die for wire drawing. After processing, the surface of the metal wire is still coated with lubricating oil. The metal wire then enters the cleaning cylinder, where the water supply component delivers cleaning fluid to the cleaning head. All water spray heads spray the cleaning fluid onto the metal wire to flush and clean the lubricating oil on it. The used cleaning fluid is then transported back to the water supply component for recycling through the recovery pipe. When the metal wire exits the cleaning cylinder, its surface is still coated with cleaning fluid. The metal wire enters the water absorption section, where the water absorption section absorbs the remaining cleaning fluid, thereby reducing the probability of residual cleaning fluid contaminating the metal wire and improving the quality of the metal wire.

[0023] 2. The pulley assembly connects the motor and any pulley in a rotatable manner. The motor drives any pulley to rotate. The gear assembly connects the inner and outer pulleys. Driven by any pulley, the gear assembly pushes another pulley on the same rod to rotate in the opposite direction. The inner and outer discs then rotate in opposite directions, causing the first and second sponge rings to rotate in opposite directions to wipe the metal wires, thus improving the sponge wiping efficiency and the quality of the metal wires.

[0028] The present application will be further described in detail below with reference to all the accompanying drawings.

[0029] This application discloses a metal wire drawing preheating device.

[0030] Example 1: Reference Figure 1 A metal wire drawing preheating device includes a frame 1, on which a traction component 2, a lubricating component 3, a preheating component 14, a forming die 4, a filter cylinder 5, an oil storage tank 12, a cleaning cylinder 6, a water supply component 13, and a water absorption section 7 are sequentially arranged. The traction component 2 includes a take-up drum 22 and an unwinding drum 21, which are respectively located at both ends of the frame 1. The unwinding drum 21 is wound with the metal wire to be processed. The take-up drum 22 rotates and pulls one end of the metal wire, causing the metal wire to pass sequentially through the lubricating component 3, the preheating component 14, the forming die 4, the filter cylinder 5, the cleaning cylinder 6, and the water absorption section 7 in a straight line. After rolling in a straight line, the metal wire is wound onto the take-up drum 22.

[0031] Reference Figure 1 The lubricating component 3 is rectangular and installed on the upper end of the frame 1. A groove 31 is vertically formed in the middle of the upper surface of the lubricating component 3, with both ends closed. The groove 31 is filled with lubricating oil. Multiple through-slots 32 are horizontally formed on the upper surface of the lubricating component 3 for the metal wire to pass through. The through-slots 32 are located on the side of the lubricating component 3 near the unwinding drum 21. The lubricating oil level is higher than the through-slots 32, and the unwinding drum 21 is lower than the take-up drum 22. A rubber pad 33 is provided at the end of the through-slot 32 near the unwinding drum 21. The rubber pad 33 has a through hole 34 adapted to the metal wire. The metal wire passes through the through hole 34 from bottom to top and contacts the lubricating oil, thus providing continuous lubrication. A support wheel 11 is fixed on the frame 1, located behind the lubricating component 3. The support wheel 11 supports the metal wire after it passes through the through-slots 32, ensuring that the lubricated metal wire is horizontal and straight.

[0032] Reference Figure 1 The preheating component 14 is cylindrical and includes a heating ring and a vertical rod. The vertical rod is fixedly connected to the upper end of the frame 1, and the heating ring is fixedly connected to the upper end of the vertical rod. After lubrication, the metal wire passes through the heating ring. When the heating ring is working, it generates heat and heats the metal wire, reducing the hardness of the metal wire so that it can pass through the forming die 4, while reducing the wear of the metal wire and the forming die 4. The preheating component 14 can be connected to the heating ring to heat the lubricating fluid, thereby preheating the metal wire.

[0033] Reference Figure 1 and Figure 2The forming mold 4 is disc-shaped and rotatably connected to the preheating component 14. The forming mold 4 has multiple holes 42 of different diameters along its circumference. A rotating shaft 41 is located at the center of the forming mold 4 and is rotatably connected to the forming mold 4. Supports 43 are provided on both sides of the forming mold 4. The supports 43 are rotatably connected to the frame 1 in the direction close to or away from the forming mold 4. The supports 43 are provided with fixing bolts 44. The forming mold 4 has several threaded holes 45 that are adapted to the fixing bolts 44 along its circumference. The fixing bolts 44 pass through the supports 43 and are threadedly connected to any of the threaded holes 45 to fix the forming mold 4. The required diameter hole 42 is rotated to the top of the forming mold 4 and fixed. The metal wire passes through the hole 42 and is drawn. The forming mold 4 is rotated to adapt to metal wires of different diameters.

[0034] Reference Figure 1 and Figure 2 The filter cylinder 5 is cylindrical and is fixedly installed in the molding mold 4. The inner wall of the filter cylinder 5 is provided with multiple circumferentially distributed clamping plates 51. All clamping plates 51 have gaps in the middle to allow the metal wire to pass through. All clamping plates 51 are in contact with the metal wire. After the metal wire passes through, the clamping plates 51 scrape off the surface lubricant. The clamping plates 51 are made of elastic material to reduce the probability of wear on the passing metal wire. An oil storage tank 12 is fixed on the frame 1. The oil storage tank 12 is detachable. The scraped lubricating oil flows along the clamping plate 51 to the bottom of the filter cylinder 5 under gravity. The bottom of the filter cylinder 5 is connected to an oil outlet pipe 53. A filter screen 52 is provided at the connection between the oil outlet pipe 53 and the filter cylinder 5. The other end of the oil outlet pipe 53 is connected to the oil storage tank 12. The lubricating oil flows into the oil storage tank 12 through the oil outlet pipe 53 for storage. When the lubricating oil in the oil storage tank 12 reaches a certain amount, the oil storage tank 12 can be removed and the lubricating oil poured into the groove 31 to recover the lubricating oil, thereby improving the utilization rate of the lubricating oil.

[0035] Reference Figure 1 and Figure 2 The cleaning cylinder 6 is cylindrical and is fixedly installed behind the filter cylinder 5. The cleaning cylinder 6 is connected to a recovery pipe 64, and the other end of the recovery pipe 64 is connected to a water supply component 13. The water supply component 13 is tank-shaped and equipped with a water pump 131. A water inlet pipe 63 is connected to the top of the cleaning cylinder, and the other end of the water inlet pipe 63 is connected to the water supply component 13. The water supply component 13 is used to store the cleaning liquid and delivers the cleaning liquid to the water inlet pipe 63 through the water pump 131.

[0036] Reference Figure 1 and Figure 2Multiple spray heads 62 are installed on the inner wall of the cleaning cylinder 6. The spray heads 62 are connected to the water supply component 13 through the water inlet pipe 63. All spray heads 62 are distributed circumferentially and all spray heads 62 are facing the axis of the cleaning cylinder 6. The water supply component 13 delivers the cleaning fluid to the spray heads 62. All spray heads 62 spray the cleaning fluid onto the metal wire to rinse and clean the lubricating oil remaining on the surface of the metal wire. After cleaning, the cleaning fluid flows back to the water supply component 13 through the recovery pipe 64 to realize the recycling of the cleaning fluid.

[0037] Reference Figure 1 and Figure 2 The cleaning cylinder 6 is fixed with baffles 61 on both sides. The baffles 61 are conical in shape and their cross-section gradually decreases in the direction away from the cleaning cylinder 6. They are also provided with through holes in the transverse direction. The metal wire passes through the through holes into the cleaning cylinder 6. When the cleaning cylinder 6 is working, the baffles 61 prevent the cleaning liquid sprayed by the spray head 62 from overflowing from the end, thereby reducing the loss of cleaning liquid.

[0038] Reference Figure 2 and Figure 3 The water-absorbing part 7 includes an inner disc 71, an outer disc 72, a water storage box 78, a first sponge ring 712, and a second sponge ring 722. The outer disc 72 is fitted over the inner disc 71, with a gap larger than the metal wire between the inner disc 71 and the outer disc 72. The inner disc 71 and the outer disc 72 are fixedly installed on the cleaning cylinder 6. Multiple support rods 73 are provided on the frame 1 along the circumference of the outer disc 72. Inner pulleys 731 and outer pulleys 732 are rotatably connected to the support rods 73. The inner disc 71 is circumferentially opened on the side facing away from the cleaning cylinder 6. There is an annular groove 711. The outer plate 72 has an annular groove 721 circumferentially opened on the side opposite to the cleaning cylinder 6. All the inner pulleys 731 are located in the annular groove 711. All the inner pulleys 731 cooperate to support the inner plate 71 and are rolled along the annular groove 711. All the outer pulleys 732 are located in the annular groove 721. All the outer pulleys 732 cooperate to support the outer plate 72 and are rolled along the annular groove 721.

[0039] Reference Figure 2 and Figure 3 Sponge ring 712 is fixedly installed on the side of inner disc 71 near cleaning cylinder 6 and is coaxially fixed with inner disc 71. When inner disc 71 rotates, it drives sponge ring 712 to rotate. Sponge ring 722 is fixedly installed on the side of outer disc 72 near cleaning cylinder 6 and is coaxially fixed with outer disc 72. When outer disc 72 rotates, it drives sponge ring 722 to rotate. The outer edge of sponge ring 712 and the inner wall of sponge ring 722 are in contact. The metal wire passes through the middle of sponge ring 712 and sponge ring 722. Sponge ring 712 and sponge ring 722 cover the metal wire and are in contact with the outer surface of the metal wire. When the metal wire passes through sponge ring 712 and sponge ring 722 under the action of traction member 2, sponge ring 712 and sponge ring 722 cooperate to absorb the cleaning liquid on the surface of the metal wire.

[0040] Reference Figure 2 As shown in Figure 3, the frame 1 is equipped with a power component for driving the inner disk 71 and the outer disk 72 to rotate. The power component includes a motor 74, a gear set 76, and a pulley set 75. The pulley set 75 includes a first pulley 751, a second pulley 752, and a belt 753. The motor 74 is fixedly connected to the frame 1. The output shaft of the motor 74 is coaxially and rotatably connected to the first pulley 751. When the motor 74 rotates, it drives the first pulley 751 to rotate. The outer pulley 732 is coaxially and rotatably connected to the second pulley 752. When the second pulley 752 rotates, it drives the outer pulley 732 to rotate. The belt 753 is sleeved on the outside of the first pulley 751 and the second pulley 752 and is tumbledly connected to the first pulley 751 and the second pulley 752. When the first pulley 751 rotates, it drives the second pulley 752 to rotate through the belt 753, so that the second pulley 752 drives the corresponding outer pulley 732 to rotate. The outer pulley 732 drives the outer disk 72 to rotate.

[0041] Reference Figure 2 and Figure 3 The gear set 76 includes gear 1 761 and gear 2 762, and the gear set 76 is located on the same support rod 73. Gear 1 761 is coaxially fixed with inner pulley 731, and gear 2 762 is coaxially fixed with outer pulley 732. Gear 1 761 and gear 2 762 mesh. When gear 1 761 rotates, it drives the corresponding inner pulley 731 to rotate through gear 2 762. In turn, the inner pulley 731 drives the inner disk 71 to rotate through the inner pulley 731. The outer disk 72 rotates under the drive of motor 74. At this time, the inner disk 71 and the outer disk 72 rotate in opposite directions. Thus, sponge ring 1 712 and sponge ring 2 722 rotate in opposite directions, so that the metal wire is subjected to frictional forces in opposite directions. This helps to keep the metal wire in balance and clean the metal wire from both sides, which helps to improve the cleaning efficiency of sponge ring 1 712 and sponge ring 2 722 and improve the quality of metal wire drawing. After absorbing water at any point, sponge ring 712 and sponge ring 722 continue to rotate to change positions and continue absorbing cleaning fluid for the metal wire, reducing the probability of the metal wire being contaminated by the cleaning fluid.

[0042] Reference Figure 2 and Figure 3The inner disc 71 has an upper column 771 on the side near the cleaning cylinder, and the outer disc 72 has a lower column 772 on the side near the cleaning cylinder. The frame 1 is fixedly connected to a rotating shaft 77. The upper column 771 and the lower column 772 are both sleeved on the outside of the rotating shaft 77 and rotatably connected to the rotating shaft 77. The upper column 771 is in close contact with the first sponge ring 712, and the upper column 771 cooperates with the inner disc 71 to squeeze the first sponge ring 712. When the first sponge ring 712 rotates, the upper column 771 is driven to rotate by friction, thereby squeezing out the water in the first sponge ring 712. The lower column 772 is in close contact with the second sponge ring 722, and the lower column 772 cooperates with the outer disc 72 to squeeze the second sponge ring 722. When the second sponge ring 722 rotates, the lower column 772 is driven to rotate by friction, thereby squeezing out the water in the second sponge ring 722. A water storage box 78 is fixedly mounted on the frame 1, located below sponge ring 712 and sponge ring 722. The squeezed cleaning fluid flows into the water storage box 78 under gravity. Sponge rings 712 and 722 continuously absorb water for the passing metal wire, improving their cleaning efficiency and thus enhancing the quality of metal wire drawing.

[0043] The implementation principle of the metal wire drawing preheating device in this application embodiment is as follows: the traction member 2 pulls the metal wire through the lubrication member 3, the preheating member 14, the forming mold 4, the filter cylinder 5, the cleaning cylinder 6, and the water absorption part 7 in sequence. The cleaning cylinder 6 filters and recovers the lubricating liquid remaining on the surface of the metal wire after lubrication and wire drawing. The metal wire after filtration is rinsed and sprayed inside the cleaning cylinder 6. The cleaning liquid after use is transported to the water supply member 13 for recovery through the recovery pipe 64. The baffles 61 on both sides of the cleaning cylinder 6 prevent the cleaning liquid sprayed from the water nozzle 62 from overflowing from both ends of the cleaning cylinder 6, reducing the probability of lubricating oil contamination and cleaning liquid loss. The water absorption part 7 rotates and absorbs the cleaning liquid on the surface of the metal wire, reducing the probability of the metal wire being contaminated by lubricating oil and cleaning liquid, which is beneficial to improving the wire drawing quality.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
