Description

Technical Field

[0001] The present invention relates to the technical field of metal wire drawing, and particularly relates to an annealing treatment process for a copper core wire drawing and annealing production line. Background Art

[0003] The existing wire drawing and annealing production line is mainly composed of a wire drawing device and an annealing device. First, the copper wire is drawn by the wire drawing device, and then the annealed copper wire is annealed by the annealing device. When annealing the copper wire, the copper wire needs to be preheated first, then heated to the annealing temperature, and then the copper wire is introduced into the cooling mechanism for cooling. Finally, the cooled copper wire is discharged and wound at the winding device; When cooling the copper wire, the water-cooling method is often used. The heated copper wire is passed through a cooling structure carrying a cooling water body. After the copper wire passes through the cooling water body, heat exchange occurs, so as to cool the copper wire. Finally, the surface of the copper wire is dried and then discharged. When the copper wire exchanges heat with the cooling water body, the water body boils and generates water vapor. In order to avoid the influence of water vapor on the heating of the copper wire, the existing equipment is set with the structure of the cooling device covered by a long tube body condensation. Such a structure setting causes waste of energy at the water vapor part, and after the copper wire is cooled, the water attached to the surface of the copper wire also needs to be removed by an external increasing mechanism, so that the equipment consumes more energy. In view of this, this solution proposes an annealing treatment process for a copper core wire drawing and annealing production line to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] The present invention provides Figures 1-10 The annealing process of a copper core wire drawing annealing production line shown in the figure uses a wire drawing annealing production line to draw and anneal the copper wire. The wire drawing annealing production line includes: A wire drawing cabinet 1, wherein a plurality of guides and wire drawing pieces are arranged at the top of the wire drawing cabinet 1, wherein the wire drawing pieces are arranged in the middle of the top of the wire drawing cabinet 1, and the plurality of guides are symmetrically arranged at both ends of the top of the wire drawing cabinet 1, and the plurality of guides and the wire drawing pieces are arranged along the horizontal transverse center, wherein the plurality of guides are used to lead the copper wire to be drawn into and out of the wire drawing pieces, and the wire drawing pieces are used to reduce the diameter of the copper wire for wire drawing; Specifically, the guide includes: A lifting bracket 3, the lifting bracket 3 is fixedly connected to the top of the wire drawing cabinet 1; The pressing bracket 4 is fixedly connected to the top of the wire drawing cabinet 1 and is located on one side of the lifting bracket 3 , and the wire drawing piece is arranged between the opposite sides of the plurality of pressing brackets 4 .

[0029] Furthermore, a lifting roller 301 is provided on the top of the lifting bracket 3, and a pressing roller 401 is provided on the top of the pressing bracket 4. The lifting roller 301 cooperates with the pressing roller 401 for copper wire winding reversal.

[0030] It should be noted that the height of the lifting bracket 3 is much higher than that of the pressing bracket 4. The outer walls of the lifting roller 301 and the pressing roller 401 are both provided with annular groove structures, which can facilitate the restricted winding of the copper wire to be drawn. Moreover, after the lifting bracket 3 and the pressing bracket 4 cooperate, they serve as the feeding and discharging of the copper wire at the wire drawing cabinet 1. Among them, the pressing roller 401 is used to press down the copper wire to keep it at the top of the wire drawing cabinet 1, so as to maintain a stable wire drawing operation.

[0031] Specifically, the wire drawing components include: The wire drawing drum unit 5. Multiple groups of wire drawing drum units 5 are arranged on the top of the wire drawing cabinet 1 and located between multiple pressing brackets 4. The wire drawing drum unit 5 is used for copper wire traction; The wire drawing die 7. Multiple groups of wire drawing dies 7 and multiple groups of wire drawing drum units 5 are arranged at intervals on the top of the wire drawing cabinet 1; The lubrication unit 6. The lubrication unit 6 is arranged at the top of the wire drawing cabinet 1 and located on the side of the wire drawing die 7. The lubrication unit 6 is used for adding lubricant when the copper wire passes through the wire drawing die 7.

[0032] It should be noted that multiple groups of wire drawing dies 7 can be set in a step-by-step change or the same setting. According to the required outer diameter of the copper wire to be prepared, the corresponding wire drawing die 7 is selected for use. The wire drawing drum unit 5 is used for the transfer of the copper wire during the wire drawing process. In order to avoid damage to the copper wire when it passes through the wire drawing die 7, a lubricant is sprayed on the surface of the copper wire through the lubrication unit 6 before the copper wire enters the wire drawing die 7, so as to ensure the stability of the copper wire wire drawing process.

[0033] The annealing cabinet 2. The annealing cabinet 2 is arranged at the discharging end of the wire drawing cabinet 1. Inside the annealing cabinet 2, a preheating zone, a heating zone, a cooling zone and a discharging zone are arranged in sequence along the horizontal direction. The preheating zone and the heating zone are used for the step-by-step heating of the copper wire to be annealed. A cooling mechanism is arranged in the cooling zone, and a wiping mechanism is arranged in the discharging zone. A steam driving part is arranged in the cooling mechanism, and the steam driving part is used to drive the wiping mechanism to rotate.

[0034] Specifically, a feeding port 201 is opened on the side wall of the annealing cabinet 2 and located at one end close to the preheating zone, and a discharging port 202 is opened on the side wall of the annealing cabinet 2 and located at one end close to the discharging zone.

[0035] It should be noted that the copper wire after wire drawing is drawn into the annealing cabinet 2 through the feeding port 201, and the copper wire after annealing treatment is led out of the annealing cabinet 2 through the discharging port 202.

[0036] Specifically, multiple groups of preheating rollers 8 are arranged in a staggered manner in the vertical plane in the preheating zone, multiple groups of heating rollers 9 are arranged in a staggered manner in the heating zone, and a reversing roller 11 is arranged in the discharging zone. The copper wire to be annealed passes through multiple groups of preheating rollers 8, multiple groups of heating rollers 9, the cooling mechanism and the reversing roller 11 in sequence to realize the annealing treatment.

[0037] It should be noted that the preheating zone is to make the copper wire heat up evenly and avoid excessive thermal stress or local overheating caused by direct heating. The preheating temperature is usually low. The main purpose is to reduce the temperature gradient, prevent the copper wire from deforming or breaking, and provide a uniform temperature basis for the subsequent heating section. The purpose of the heating zone is to make the copper wire reach the recrystallization temperature, eliminate internal stress, and improve its mechanical properties and electrical conductivity.

[0038] The heating principle adopted in the preheating zone and the heating zone of this scheme is electric heating, which is a process method for heating the copper wire by electric current to reach the annealing temperature. The principle is to use the Joule heat generated when the current passes through the copper wire to heat the copper wire, thereby realizing annealing treatment. That is, when the current passes through the conductor, due to the existence of resistance, the electrical energy will be converted into thermal energy. The current passes through the copper wire, and the copper wire acts as a conductor. After the current is turned on, the Joule heat generated by the copper wire will recrystallize at high temperature, eliminate internal stress, and improve ductility and conductivity.

[0039] Specifically, the cooling mechanism includes: A cooling box 10, a cooling bin is provided at the bottom of the cooling box 10, a condensation box 1001 is provided at the top of the cooling box 10, a driving cavity is provided between the condensation box 1001 and the cooling box 10, a steam driving member is inserted and connected in the driving cavity, the condensation box 1001 is arranged in a circular pancake shape with multiple groups of inner corners, a guide groove 1002 is provided on the inner wall of the top of the cooling box 10 and through the driving cavity, the guide groove 1002 is used to accelerate the release of water vapor into the driving cavity, and an exhaust hole 1003 is provided at the top of the condensation box 1001; It should be noted that the condensation box 1001 is fixed to the cooling box 10 by welding, and the two are connected in series through the driving cavity. A discharge pipe is provided at the bottom of the cooling box 10 for discharging the water in the box. In the setting of this scheme, the ports of the guide groove 1002 close to the cooling bin and the driving cavity are larger than the middle area, which is convenient for water vapor to enter the guide groove 1002. After the radius is reduced, the movement of water vapor is accelerated. After the accelerated water vapor gushes into the driving cavity, it impacts the steam drive member to rotate; After the water vapor continues to float up, it will adhere to the inner wall of the condensation box 1001. Since the inner wall of the condensation box 1001 has multiple layers of concave bends, it not only increases the contact area with the water vapor, but also blocks the water vapor, so that the water vapor condenses and gathers on the inner wall of the condensation box 1001, and the gas that does not have time to condense or the gas that expands due to heat can be discharged through the exhaust hole 1003.

[0040] Blocking plates 15, multiple groups of blocking plates 15 are respectively inserted and connected to both sides of the cooling box 10, and the blocking plates 15 are used for the copper wire to enter and exit the cooling box 10; It should be noted that a hole is opened in the middle of the sealing plate 15, which ensures that the copper wire that needs to be cooled can be inserted and passed through, and the sealing plate 15 blocks the cooling chamber to prevent a large amount of water vapor from being discharged, and the sealing plate 15 can be opened to facilitate filling of cooling water into the cooling box 10.

[0041] A first reversing pulley 16, wherein multiple sets of first reversing pulleys 16 are all disposed on the top of the cooling bin, and multiple sets of first reversing pulleys 16 are respectively disposed below multiple sets of blocking plates 15; The second reversing pulley 17, multiple sets of second reversing pulleys 17 are all arranged at the bottom of the cooling bin, and the second reversing pulley 17 cooperates with the first reversing pulley 16 to guide the copper wire after annealing into the cooling bin.

[0042] It should be noted that, through the setting of the first reversing pulley 16, the copper wire is supported and guided when it enters and moves out of the cooling box 10, and the setting of the second reversing pulley 17 is to press the copper wire down to the bottom of the cooling bin, so that the copper wire can smoothly pass through the water in the cooling bin, so that it can stably achieve heat exchange and cooling in the cooling bin.

[0043] Furthermore, the steam drive component includes a connecting sleeve 13, a rotating rod 1301 is sleeved in the middle of the connecting sleeve 13, the rotating rod 1301 is rotated horizontally and longitudinally and is connected to the driving cavity, and one end of the rotating rod 1301 passes through the condensation box 1001 to drive the erasing mechanism to rotate, and the outer wall of the connecting sleeve 13 is provided with multiple groups of moving blades 1302, and the moving blades 1302 are used to drive the connecting sleeve 13 to rotate by cooperating with the steam rising from the guide groove 1002.

[0044] It should be noted that the tossing blade 1302 is made of light and thin material and needs to be resistant to high temperature and corrosion. By setting the angle of the tossing blade 1302, it cooperates with the exhaust port of the guide groove 1002, so that the discharged water vapor can impact the tossing blade 1302, and then driven by multiple tossing blades 1302, the connecting sleeve 13 rotates, and at the same time drives the rotating rod 1301 to rotate synchronously, and in order to ensure that the rotating rod 1301 can reduce energy consumption, a bearing is set at the connection between the rotating rod 1301 and the cooling box 10 to facilitate its rotation.

[0045] Specifically, the erasure agencies include: A mop drum 12, wherein a support rotating rod 1201 is sleeved in the middle of the mop drum 12, and one end of the support rotating rod 1201 is rotatably connected to the discharge area of ​​the annealing cabinet 2; The transmission belt 14 has one end of its inner wall sleeved on the end of the supporting rotating rod 1201 , and the other end of its inner wall sleeved on the through end of the rotating rod 1301 .

[0046] It should be noted that the outer wall of the mop drum 12 is surrounded by a water-absorbing cloth structure. When the copper wire that has been cooled by water is wrapped around its outer wall, the surface of the copper wire is wiped and absorbed by the cloth structure. The rotation of the mop drum 12 is driven by the supporting rotating rod 1201, and the supporting rotating rod 1201 is driven by the transmission belt 14, so that the device can save more energy.

[0047] Specifically, the annealing process includes the following steps: In the first step, the drawn copper wire is first guided by a guide member into the annealing cabinet 2; It should be noted that the copper wire after drawing is guided by the lifting roller 301 at the discharge end of the drawing cabinet 1 and then enters the annealing cabinet 2 through the feed port 201 .

[0048] In the second step, after the copper wire passes through the preheating zone and the heating zone, it is first heated to 200℃~300℃ in the preheating zone, and then heated to 400℃~700℃ in the heating zone; It should be noted that after the copper wire passes through the feed port 201 and enters the annealing cabinet 2, it is wrapped around the outer walls of multiple groups of preheating rollers 8 and multiple groups of heating rollers 9. When the copper wire passes through the outer wall of the preheating roller 8, it is electrically heated to 200°C ~ 300°C by the preheating roller 8, and then electrically heated to 400°C ~ 700°C by the heating roller 9.

[0049] In the third step, the heated copper wire is guided into the cooling mechanism, and the heated copper wire passes through the cooling water in the cooling mechanism. After heat exchange, the surface of the copper wire is cooled. At this time, the water in the cooling mechanism is heated by the copper wire to generate water vapor, and the water vapor floats up to drive the steam driving part to rotate, and driven by the steam driving part, the erasing mechanism rotates synchronously; It should be noted that after the heated copper wire is annealed, it passes through the sealing plate 15 and enters the cooling box 10. In the cooling box 10, it passes through the second reversing pulley 17 and the first reversing pulley 16, and the high-temperature copper wire is immersed in the water body in the cooling bin for heat exchange and cooling. At this time, the water body boils after being heated by the copper wire and generates water vapor. After the water vapor rises, the mirror cabinet guide groove 1002 accelerates and guides it to the drive cavity. The water vapor drives the multiple groups of moving blades 1302 to rotate, thereby driving the connecting sleeve 13 and the rotating rod 1301 to rotate. At this time, under the drive of the transmission belt 14, the supporting rotating rod 1201 rotates synchronously, and the supporting rotating rod 1201 drives the mop drum 12 to rotate synchronously.

[0050] In the fourth step, the cooled copper wire passes through the cooling mechanism, surrounds the erasing mechanism and is guided to the discharging area for discharging. When the copper wire moves around the erasing mechanism, the erasing mechanism rotates to brush the surface of the copper wire.

[0051] It should be noted that the cooled copper wire passes through the sealing plate 15 and then exits from the cooling chamber. After surrounding the outer wall of the mop cylinder 12 and then being received by the reversing roller 11, it is discharged from the discharge port 202. When the copper wire passes through the outer wall of the mop cylinder 12, the mop cylinder 12 rotates in cooperation with the movement of the copper wire to wipe and absorb water on the surface of the copper wire.

[0052] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
