Description

Technical Field

[0001] This invention relates to the field of wire drawing equipment technology, specifically to a wire drawing equipment for copper material production and processing. Background Technology

[0002] With the continuous development of technology and the rapid progress of society, the use of copper is increasing. Copper wire drawing is a pressure processing method where copper material undergoes plastic deformation under a certain tensile force, passing through a die orifice, resulting in a smaller cross-section and increased length. This is typically done using a wire drawing die. Copper wire refers to wire drawn from copper material and can be used in weaving, cables, copper brush filters, etc. Wire drawing is frequently required in the production of copper wire. A copper wire drawing machine is the equipment used to produce copper wire. During production, a copper rod is forcibly pulled through a drawing die with a diameter slightly smaller than its own. After being pulled, the diameter of the copper rod decreases, and its length increases. This process is repeated continuously, further lengthening the copper rod until it is drawn into copper wire.

[0003] Currently, in the existing copper wire drawing process, the copper material is pulled and tugged forcefully. The small contact area between the copper material and the traction device and the uneven force can lead to copper material breakage, affecting the normal wire drawing process. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A wire drawing device for copper material production and processing, comprising:

[0006] The machine body, and a controller fixedly installed on the top side of the machine body, wherein a pressing mechanism is installed on the top of the machine body;

[0007] A rotary traction mechanism is used to pull and traction the raw materials for copper production and processing. The rotary traction mechanism is installed in the middle of the top of the machine body.

[0008] The rotary traction mechanism includes a servo motor and a traction roller. The servo motor is fixedly mounted at the bottom of the machine body. The central shaft at the bottom of the traction roller is rotatably mounted at the center of the top of the machine body via a bushing. A circular oil reservoir is fixedly connected to the bottom of the outer surface of the traction roller. An annular cover is fixedly mounted to the top of the outer surface of the traction roller. An annular extension edge is fixedly connected to the bottom of the annular cover. A pressurized oil supply assembly is installed inside the circular oil reservoir. An oil passage is opened at the center of the traction roller. The oil passage is located inside the traction roller, near the top. An oil outlet is provided at the location. One end of the copper wire is spirally wound around the traction roller, and the copper wire is also wound around the two symmetrical traction rollers at the top of the machine. The spiral winding method increases the contact area between the copper wire and the traction roller. The servo motor is turned on, and the rotation of the servo motor output drives the traction roller to rotate. The traction roller rotates in a circular motion, which can rotate and traction the copper wire, so that the copper wire is subjected to uniform force, is not easy to tear, and helps to accurately draw the copper wire.

[0009] Preferably, the central shaft at the bottom of the traction roller passes through the top of the machine body and extends to its bottom. The central shaft at the bottom of the traction roller is fixedly installed to the output end of the servo motor via a coupling. The traction roller is installed vertically.

[0010] Preferably, the center of the annular cover and the center of the annular extension edge coincide with the central axis at the middle of the traction rotating roller, the material of the annular extension edge is rubber, and the oil outlet connects the top of the oil channel with the annular cover.

[0011] Preferably, the pressurized oil supply assembly includes a sliding guide rod. The outer circular surface of the sliding guide rod is slidably mounted to the surface of a circular oil reservoir via a guide sleeve. One end of the sliding guide rod is fixedly connected to an arc-shaped pressure plate, which is installed inside the circular oil reservoir. An elastic bladder is fixedly installed between the center of the surface of the circular oil reservoir and the traction rotating roller. An oil outlet check valve is installed at the oil outlet of the inner cavity of the elastic bladder. A roller is rotatably mounted on the end of the sliding guide rod away from the arc-shaped pressure plate. An oil inlet is installed at the oil inlet at the bottom of the surface of the elastic bladder. A one-way valve is used, and a reset elastic plate is fixedly connected between the side of the arc-shaped pressure plate and the outer circular surface of the traction rotating roller. The circular oil reservoir drives the entire pressurized oil supply assembly to rotate continuously. The roller disengages from the surface of the support base plate, causing the pushing force on the roller to disappear. Under the elastic force of the reset elastic plate, the arc-shaped pressure plate moves in the opposite direction to reset. The compressive force on the elastic bladder disappears, and the lubricating oil in the circular oil reservoir re-enters the interior of the elastic bladder through the oil inlet one-way valve to facilitate subsequent oil supply.

[0012] Preferably, there are three sliding guide rods, and the three sliding guide rods are evenly distributed on the surface of the circular oil reservoir. The oil outlet of the one-way valve is connected to the bottom end of the oil passage, and the reset elastic sheet is arc-shaped.

[0013] Preferably, the extrusion mechanism includes a primary extrusion module and a secondary extrusion module. The primary extrusion module is installed at one end of the top of the machine body, and the secondary extrusion module is installed at the top of the machine body and at the end away from the primary extrusion module.

[0014] Preferably, the primary extrusion module includes a support base plate. The bottom of the support base plate is fixedly installed to the side of the top of the machine body by screws. A trapezoidal block is detachably fixedly installed on the top of the support base plate. A right-angled reinforcing rib is fixedly installed between the surface of the trapezoidal block and the surface of the support base plate. A drawing hole is opened at the center of the interior of the trapezoidal block. A rubber ring is installed on the side of the interior of the trapezoidal block. A discharge guide wheel is rolled on the surface of the trapezoidal block and near the traction roller. An oil suction pump is fixedly installed on the side of the surface of the trapezoidal block. A bent oil pipe connects the oil outlet at the top of the oil suction pump to the top of the trapezoidal block, allowing one end of the pre-treated copper material to be drawn from the trapezoidal block. The copper wire passes through the drawing hole at the center of the block, and one end of the copper material is spirally wound around the surface of the traction roller. The traction roller rotates, and the copper material is squeezed through the drawing hole, which makes the copper material thinner, thus performing preliminary wire drawing. The secondary extrusion module has the same structure as the primary extrusion module, except that the diameter of the drawing hole in the primary extrusion module is larger than that in the secondary extrusion module. As the traction roller continues to rotate, the copper wire after the preliminary wire drawing is completed passes through the drawing hole in the secondary extrusion module, thus performing secondary wire drawing. By adopting a step-by-step wire drawing method, the copper wire is drawn in stages, which reduces the risk of breakage.

[0015] Using the suction force of the oil pump, the oil inlet at the bottom of the pump draws oil from the circular oil reservoir. The lubricating oil is then transported through a bent oil pipe from the outlet into the rubber ring inside the trapezoidal block. As the copper wire passes through the center of the rubber ring, the lubricating oil is evenly coated on the surface of the copper wire, providing lubrication for subsequent wire drawing, reducing frictional resistance, and preventing scratches on the surface of the copper wire, thus protecting it. As the drawn copper wire moves out from between two symmetrical discharge guide rollers, the lubricating oil is carried away and drawn back into the circular oil reservoir for easy oil circulation.

[0016] Preferably, the surface of the supporting substrate is arc-shaped, the rubber ring is installed at the feed inlet of the drawing hole, the oil suction port at the bottom of the oil suction pump extends into the interior of the circular oil storage shell, the discharge guide wheel is installed vertically, and the oil outlet of the bent oil pipe at the end away from the oil suction pump is installed directly above the rubber ring. As the traction rotating roller is driven to rotate by the output end of the servo motor, the circular oil storage shell is driven to rotate as well, thus driving the entire pressurized oil supply assembly to rotate circumferentially. Through the contact between the roller and the surface of the supporting substrate, the roller is pushed by the arc-shaped surface of the supporting substrate, and under the sliding connection of the sliding guide rod, the arc-shaped pressure plate can be moved towards the side closer to the traction rotating roller. The elastic bladder and the reset elastic plate can be squeezed. The elastic bladder deforms under compression, and the reset elastic plate deforms elastically under pressure. Under the control of the oil flow by the oil outlet check valve and the oil inlet check valve, the lubricating oil in the squeezed elastic bladder enters the interior of the oil passage. As the oil pressure in the oil passage increases, the lubricating oil enters the interior of the annular cover from the oil outlet and flows down along the surface of the traction roller. The annular extension edge is made of rubber, which is flexible and allows the lubricating oil in the annular cover to flow down slowly. This lubricating oil can then wet the copper wire spirally wound on the surface of the traction roller. By using the flow of lubricating oil, the heat of the drawn copper wire is carried away, thus cooling the copper wire.

[0017] Preferably, an auxiliary mechanism is installed at the feeding end of the top of the machine body. The auxiliary mechanism includes a bracket, the bottom of which is fixed to the feeding end of the top of the machine body by screws. A first bending plate and a second bending plate are sequentially hinged to the top of the surface of the bracket. Wiping blocks are fixedly connected to the middle of the surface of the first bending plate and the middle of the surface of the second bending plate. An elastic pulling strip is fixedly connected to the first bending plate and the second bending plate. When the two symmetrical first bending plates and the second bending plate are bent outward, the elastic pulling strip is stretched, which increases the space between the first bending plate and the second bending plate. The two symmetrical wiping blocks of the copper material pass through the middle of the plate, and the first bending plate and the second bending plate are released. Under the elastic pulling force of the elastic pulling strip, the first bending plate and the second bending plate wipe the surface of the copper material through the wiping blocks, removing dust and impurities from the surface of the copper material.

[0018] Preferably, the second bending plate is installed directly below the first bending plate, and the wiping block is made of high-density sponge.

[0019] This invention provides a wire drawing device for copper material production and processing. It has the following beneficial effects:

[0020] I. This copper wire drawing equipment spirally winds one end of the copper wire raw material around a traction roller, and also winds the copper wire around two symmetrical traction rollers at the top of the machine. The spiral winding method increases the contact area between the copper wire and the traction roller. The rotation of the servo motor output can drive the traction roller to rotate. The circumferential rotation of the traction roller can perform rotary winding and traction on the copper wire, making the copper wire evenly stressed, less prone to tearing, and helping to accurately draw the copper wire.

[0021] II. The copper wire drawing equipment for copper material production and processing spirally winds one end of the copper raw material around the surface of the traction roller. The traction roller rotates, and the copper raw material is squeezed through the drawing hole, which makes the copper raw material thinner, thus performing preliminary wire drawing. The secondary extrusion module has the same structure as the primary extrusion module, except that the diameter of the drawing hole in the primary extrusion module is larger than that in the secondary extrusion module. As the traction roller continues to rotate, the copper wire after the preliminary wire drawing is completed passes through the drawing hole in the secondary extrusion module, thus performing secondary wire drawing. By adopting a step-by-step wire drawing method, the copper wire is drawn in stages, which reduces the likelihood of breakage.

[0022] III. The wire drawing equipment for copper material production and processing utilizes the suction force of an oil pump to draw oil from the circular oil reservoir at the bottom of the pump. Under the transport of the bent oil pipe, the lubricating oil is discharged from the outlet through the bent oil pipe into the rubber ring inside the trapezoidal block. As the copper wire passes through the center of the rubber ring, the lubricating oil is evenly coated on the surface of the copper wire, providing lubrication for subsequent wire drawing, reducing frictional resistance, and preventing scratches on the surface of the copper wire, thus protecting it. As the drawn copper wire moves out from between two symmetrical discharge guide rollers, the lubricating oil is carried away and drawn back into the circular oil reservoir for easy oil circulation.

[0023] IV. The wire drawing equipment for copper material production and processing utilizes the pushing force of the rollers on the arc-shaped surface of the supporting substrate to move the arc-shaped pressure plate closer to the traction rotating roller, thereby squeezing the elastic bladder and the reset elastic sheet. Under the control of the oil flow by the oil outlet check valve and the oil inlet check valve, the lubricating oil in the squeezed elastic bladder enters the interior of the oil passage. As the oil pressure in the oil passage increases, the lubricating oil enters the interior of the annular cover from the oil outlet and flows downward along the surface of the traction rotating roller. The annular extension edge is made of rubber, which is flexible and allows the lubricating oil in the annular cover to flow down slowly, thus wetting the copper wire spirally wound on the surface of the traction rotating roller. The flow of lubricating oil carries away the heat of the drawn copper wire, thereby cooling the copper wire.

[0024] V. The wire drawing equipment for copper material production and processing drives the entire pressure supply component to rotate continuously through the circular oil storage shell. By disengaging the roller from the surface of the support base plate, the pushing force on the roller disappears. Under the elastic force of the reset elastic plate, the arc-shaped pressure plate moves in the opposite direction to reset. The compressive force on the elastic bladder disappears. By utilizing the expansion of the elastic bladder volume, the lubricating oil in the circular oil storage shell re-enters the interior of the elastic bladder through the oil inlet check valve for subsequent oil supply.

[0025] VI. The wire drawing equipment for copper material production and processing moves two symmetrical first and second bending plates outward, stretching the elastic pull strip and increasing the space between the first and second bending plates. The copper material is then passed through the middle of the two symmetrical wiping blocks, and the first and second bending plates are released. Under the elastic pull of the elastic pull strip, the first and second bending plates wipe the surface of the copper material through the wiping blocks, removing dust and impurities from the surface of the copper material.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] First embodiment, such as Figures 1 to 5 As shown, the present invention provides a technical solution:

[0037] A wire drawing device for copper material production and processing, comprising:

[0038] The machine body 1, and the controller 2 fixedly installed on the top side of the machine body 1, and the extrusion mechanism 3 is installed on the top of the machine body 1;

[0039] Rotary traction mechanism 4 is used to pull and traction the raw materials for copper production and processing. Rotary traction mechanism 4 is installed in the middle of the top of the machine body 1.

[0040] The rotary traction mechanism 4 includes a servo motor 41 and a traction roller 42. The servo motor 41 is fixedly installed at the bottom of the machine body 1. The central shaft at the bottom of the traction roller 42 is rotatably installed at the middle of the top of the machine body 1 via a bushing. A circular oil reservoir 43 is fixedly connected to the bottom of the outer surface of the traction roller 42. An annular cover 44 is fixedly installed at the top of the outer surface of the traction roller 42. An annular extension edge 45 is fixedly connected to the bottom of the annular cover 44. A pressurized oil supply assembly 46 is installed inside the circular oil reservoir 43. An oil passage 47 is opened at the center of the traction roller 42. The interior of the traction roller 42 and An oil outlet 48 is provided near the top. The operator spirally winds one end of the copper wire material around the traction roller 42, and winds the copper wire around both of the two symmetrical traction rollers 42 at the top of the machine body 1. The spiral winding method of the copper wire increases the contact area between the copper wire and the traction roller 42. The servo motor 41 is turned on to work. The rotation of the output end of the servo motor 41 drives the traction roller 42 to rotate. The traction roller 42 rotates in a circular motion, which can rotate and traction the copper wire, so that the copper wire is subjected to uniform force and is not easy to tear.

[0041] The central shaft at the bottom of the traction roller 42 passes through the top of the machine body 1 and extends to its bottom. The central shaft at the bottom of the traction roller 42 is fixedly installed to the output end of the servo motor 41 through a coupling. The traction roller 42 is installed vertically.

[0042] The center of the annular cover 44 and the center of the annular extension edge 45 coincide with the central axis of the traction rotating roller 42. The material of the annular extension edge 45 is rubber. The oil outlet 48 connects the top of the oil channel 47 with the annular cover 44.

[0043] The pressurized oil supply assembly 46 includes a sliding guide rod 461. The outer circular surface of the sliding guide rod 461 is slidably mounted to the surface of the circular oil reservoir 43 via a guide sleeve. One end of the sliding guide rod 461 is fixedly connected to an arc-shaped pressure plate 462, which is installed inside the circular oil reservoir 43. An elastic bladder 463 is fixedly installed between the center of the surface of the circular oil reservoir 43 and the traction rotating roller 42. An oil outlet check valve 464 is installed at the oil outlet of the inner cavity of the elastic bladder 463. A roller 465 is rolled on the end of the sliding guide rod 461 away from the arc-shaped pressure plate 462. An oil inlet check valve 466 is installed at the oil inlet at the bottom of the surface of the elastic bladder 463. A reset elastic plate 467 is fixedly connected between the edge of the surface of the pressure plate 462 and the outer circular surface of the traction rotating roller 42. The circular oil reservoir 43 drives the entire pressure supply assembly 46 to rotate continuously. The roller 465 disengages from the surface of the support base plate 311, causing the pushing force on the roller 465 to disappear. Under the elastic force of the reset elastic plate 467, the arc-shaped pressure plate 462 moves in the opposite direction to reset. The squeezing force on the elastic bladder 463 disappears. Due to the expansion of the volume of the elastic bladder 463, the lubricating oil in the circular oil reservoir 43 re-enters the interior of the elastic bladder 463 through the oil inlet check valve 466 for subsequent oil supply.

[0044] There are three sliding guide rods 461, and the three sliding guide rods 461 are evenly distributed on the surface of the circular oil reservoir 43. The oil outlet of the one-way valve 464 is connected to the bottom end of the oil passage 47. The reset elastic plate 467 is arc-shaped.

[0045] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 1 to 7 As shown:

[0046] The extrusion mechanism 3 includes a primary extrusion module 31 and a secondary extrusion module 32. The primary extrusion module 31 is installed at one end of the top of the machine body 1, and the secondary extrusion module 32 is installed at the top of the machine body 1 and at the end away from the primary extrusion module 31.

[0047] The primary extrusion module 31 includes a support base plate 311. The bottom of the support base plate 311 is fixedly installed to the side of the top of the machine body 1 by screws. A trapezoidal block 312 is detachably fixedly installed on the top of the support base plate 311. A right-angled reinforcing rib 313 is fixedly installed between the surface of the trapezoidal block 312 and the surface of the support base plate 311. A drawing hole 314 is opened in the center of the trapezoidal block 312. A rubber ring 315 is installed on the side of the trapezoidal block 312. A discharge guide wheel 316 is rolled on the surface of the trapezoidal block 312 and near the traction roller 42. An oil suction pump 317 is fixedly installed on the side of the surface of the trapezoidal block 312. A bent oil pipe 318 connects the oil outlet at the top of the oil suction pump 317 and the top of the trapezoidal block 312 to extrude the pre-treated copper material. One end of the raw material passes through the drawing hole 314 at the center of the trapezoidal block 312, and the copper raw material is spirally wound around the surface of the traction roller 42. The traction roller 42 rotates, and the copper raw material is squeezed through the drawing hole 314, which makes the copper raw material thinner, thus performing preliminary wire drawing. The secondary extrusion module 32 has the same structure as the primary extrusion module 31, except that the diameter of the drawing hole in the primary extrusion module 31 is larger than that in the secondary extrusion module 32. As the traction roller 42 continues to rotate, the copper wire after the preliminary wire drawing is passed through the drawing hole in the secondary extrusion module 32, and the copper wire is drawn a second time. By adopting a step-by-step wire drawing method, the copper wire is drawn in stages, which reduces the risk of breakage.

[0048] The operator starts the oil suction pump 317. Utilizing the suction force of the pump 317, oil is drawn from the circular oil reservoir 43 through the suction port at the bottom of the pump 317. Under the transport of the bent oil pipe 318, the lubricating oil is discharged from the outlet of the bent oil pipe 318 into the rubber ring 315 inside the trapezoidal block 312. As the copper wire passes through the center of the rubber ring 315, the lubricating oil is evenly coated on the surface of the copper wire, providing lubrication for subsequent wire drawing, reducing frictional resistance, and preventing scratches on the surface of the copper wire, thus protecting it. As the drawn copper wire moves out from between the two symmetrical discharge guide rollers 316, the lubricating oil is carried away and drawn back into the circular oil reservoir 43, facilitating oil circulation.

[0049] The surface of the support substrate 311 is arc-shaped. The rubber ring 315 is installed at the feed port of the pull hole 314. The oil suction port at the bottom of the oil suction pump 317 extends into the interior of the circular oil storage shell 43. The discharge guide wheel 316 is installed vertically. The oil outlet of the bent oil pipe 318, away from the oil suction pump 317, is installed directly above the rubber ring 315. As the traction rotating roller 42 is driven to rotate by the output end of the servo motor 41, the circular oil storage shell 43 is driven to rotate as well. This drives the entire pressurized oil supply assembly 46 to rotate in a circle. Through the contact between the roller 465 and the surface of the support substrate 311, the roller 465 is pushed by the arc-shaped surface of the support substrate 311. Under the sliding connection of the sliding guide rod 461, the arc-shaped pressure plate 462 can be moved towards the side closer to the traction rotating roller 42. When the movement is made, the elastic bladder 463 and the reset elastic plate 467 can be squeezed. The elastic bladder 463 is compressed and deformed, and the reset elastic plate 467 is compressed and deformed elastically. Under the control of the oil flow by the oil outlet check valve 464 and the oil inlet check valve 466, the lubricating oil in the compressed elastic bladder 463 enters the interior of the oil passage 47. As the oil pressure in the oil passage 47 increases, the lubricating oil enters the interior of the annular cover 44 from the oil outlet 48 and flows down along the surface of the traction rotating roller 42. The annular extension edge 45 is made of rubber and has good flexibility, so the lubricating oil in the annular cover 44 flows down slowly and can wet the copper wire spirally wound on the surface of the traction rotating roller 42. The flow of lubricating oil carries away the heat of the copper wire after drawing and cools the copper wire.

[0050] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 1 to 8 As shown:

[0051] An auxiliary mechanism 5 is installed at the feed end of the top of the machine body 1. The auxiliary mechanism 5 includes a bracket 51. The bottom of the bracket 51 is fixed to the feed end of the top of the machine body 1 by screws. A first bending plate 52 and a second bending plate 53 are sequentially hinged to the top surface of the bracket 51. Wiping blocks 54 are fixedly connected to the middle of the surface of the first bending plate 52 and the middle of the surface of the second bending plate 53. An elastic pull strip 55 is fixedly connected to the first bending plate 52 and the second bending plate 53. The operator moves the two symmetrical first bending plates... The first bending plate 52 and the second bending plate 53 are bent outwards, and the elastic pulling strip 55 is stretched, which increases the space between the first bending plate 52 and the second bending plate 53. The space between the two symmetrical wiping blocks 54 of the copper material is passed through, and the first bending plate 52 and the second bending plate 53 are released. Under the elastic pulling force of the elastic pulling strip 55, the first bending plate 52 and the second bending plate 53 wipe the surface of the copper material through the wiping blocks 54 to remove dust and impurities from the surface of the copper material.

[0052] The second bending plate 53 is installed directly below the first bending plate 52, and the wiping block 54 is made of high-density sponge.

[0053] In use, the operator first pours an appropriate amount of lubricating oil into the circular oil reservoir 43, so that the level of the lubricating oil exceeds the top of the elastic bladder 463. At this time, the operator moves the two symmetrical first bending plates 52 and second bending plates 53 outward, and the elastic pulling strip 55 is stretched, which increases the space between the first bending plates 52 and second bending plates 53. The two symmetrical wiping blocks 54 of the copper material are passed through the middle, and the first bending plates 52 and second bending plates 53 are released. Under the elastic pulling force of the elastic pulling strip 55, the wiping block 54 in the middle of the first bending plates 52 and second bending plates 53 is tightly attached to the surface of the copper material.

[0054] One end of the pre-treated copper material is passed through the drawing hole 314 at the center of the trapezoidal block 312, and the worker spirally winds one end of the copper wire material around the traction rotating roller 42, and winds the copper wire around both of the two symmetrical traction rotating rollers 42 at the top of the machine body 1.

[0055] At this time, the servo motor 41 is turned on to work. The rotation of the output end of the servo motor 41 can drive the traction roller 42 to rotate. The traction roller 42 rotates in a circle, which can rotate and wind the copper wire, so that the copper wire is evenly stressed and is not easy to tear.

[0056] At the same time, the wiping block 54 wipes the surface of the copper material to remove dust and impurities.

[0057] Furthermore, the traction roller 42 is rotated, and the copper raw material is squeezed through the drawing hole 314, which makes the copper raw material thinner, thereby performing preliminary wire drawing. The secondary extrusion module 32 has the same structure as the primary extrusion module 31, except that the diameter of the drawing hole in the primary extrusion module 31 is larger than that in the secondary extrusion module 32. As the traction roller 42 continues to rotate, the copper wire after the preliminary wire drawing is completed passes through the drawing hole in the secondary extrusion module 32, and the copper wire is drawn a second time. By adopting a step-by-step wire drawing method, the copper wire is drawn in stages, which makes it less likely to break.

[0058] The operator starts the oil suction pump 317 and uses its suction force to draw oil from the circular oil reservoir 43 through the suction port at the bottom of the oil suction pump 317. Under the transportation of the bent oil pipe 318, the lubricating oil is discharged from the oil outlet through the bent oil pipe 318 into the rubber ring 315 inside the trapezoidal block 312. As the copper wire passes through the center of the rubber ring 315, the lubricating oil is evenly coated on the surface of the copper wire, which lubricates the copper wire for subsequent wire drawing, reduces frictional resistance, and prevents scratches on the surface of the copper wire, thus protecting the copper wire. As the drawn copper wire moves out from between the two symmetrical discharge guide rollers 316, the lubricating oil is carried away and drawn back into the circular oil reservoir 43 for easy oil circulation.

[0059] Moreover, the copper wire is spirally wound, which increases the contact area between the copper wire and the traction roller 42, making the copper wire less likely to break.

[0060] The circular oil reservoir 43 drives the pressurized oil supply assembly 46 to rotate continuously. The roller 465 disengages from the surface of the support base plate 311, causing the pushing force on the roller 465 to disappear. Under the elastic force of the reset elastic plate 467, the arc-shaped pressure plate 462 moves in the opposite direction to reset. The compressive force on the elastic bladder 463 disappears. Due to the expansion of the volume of the elastic bladder 463, the lubricating oil in the circular oil reservoir 43 re-enters the interior of the elastic bladder 463 through the oil inlet check valve 466 for subsequent oil supply.
