Description

Technical Field

[0001] The present invention relates to the field of copper wire cutting, and more specifically, to a copper alloy wire shearing device and its usage method. Background Art

[0002] Copper alloy wires are slender metal wire materials made with copper as the matrix, adding one or more alloying elements (such as tin, zinc, nickel, aluminum, bismuth, iron, silicon, cobalt, molybdenum, zirconium, etc.), and through processes such as smelting, continuous ingot casting, hot / cold working, wire drawing, annealing, etc.

[0003] After processes such as wire drawing and annealing, copper alloy wires need to be sheared. Currently, the shearing methods for copper alloy wires include mechanical shearing, ultrasonic / laser cutting, wire electrical discharge machining, etc. Mechanical shearing has the advantages of mature equipment, high speed, and being easy to integrate with an automated production line. Therefore, it is the most commonly used shearing method on the current production line. Fly shearing belongs to a type of mechanical shearing method. The scissors blades used in fly shearing move at the same speed as the wire. When the moving speed of the blades approaches the moving speed of the wire, the instantaneous resultant force of the two blades cuts the wire. The wire is continuously fed out, and the production line does not need to stop due to shearing. Since the fly shearing production line runs at high speed and does not stop, under high-frequency shearing, the alloy or coated blades gradually become dull under high-temperature and high-pressure impacts, the cutting edge gap increases, which will cause a decline in the cutting quality. When the wear is severe, even chipping will occur, resulting in the blades piercing the wire material, causing the wire to break and twist. Summary of the Invention

[0004] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a copper alloy wire shearing device and its usage method.

[0005] To solve the above problems, the present invention adopts the following technical solutions.

[0006] A copper alloy wire shearing device includes a fixed seat, a driving component connected to the fixed seat, and a moving-along part connected to the driving component; The moving-along part includes a flying seat, a hollow groove opened inside the flying seat, and a shearing component connected inside the flying seat; The shearing component includes a first moving groove opened inside the flying seat, two sliding seats symmetrically slidably connected to the inner wall of the first moving groove, two wear-sharing parts respectively connected inside the two sliding seats, a pressing column fixedly connected to one side of one of the sliding seats and extending outwards through the flying seat, a reset part connected inside the first moving groove to reset the sliding seats, and a transmission part connected inside the first moving groove to drive the two sliding seats to move relatively; The wear-sharing part includes a second moving groove opened inside the sliding seat, a moving seat slidably connected in the second moving groove, a lead screw rotatably connected in the second moving groove and screwed into the moving seat, a shearing tool fixedly connected to one side of the moving seat, and a motor two with an output shaft fixedly connected to one side of each of the two sliding seats and connected to the lead screw.

[0007] Further, the driving component includes two slide rails fixed on one side of the fixed seat, a movable plate slidably connected to the slide rails, a chute opened inside the movable plate, a slider slidably connected in the chute, a pressing seat fixed on one side of the slider, an eccentric wheel rotatably connected to one side of the fixed seat and rotatably connected to one side of the slider, and a first motor fixed on the other side of the fixed seat and having an output shaft fixedly connected to the eccentric wheel. The flying seat is fixed on one side of the movable plate.

[0008] Further, the resetting part includes a plurality of guide posts with both ends fixed to the inner wall of the first movable groove, and springs sleeved outside the guide posts. Both of the sliding seats are movably sleeved outside the guide posts, and both ends of the springs are respectively connected to the sliding seats and the inner wall of the first movable groove.

[0009] Further, the transmission part includes two sets of racks respectively fixed on both sides of the two sliding seats, and two first gears rotatably connected inside the flying seat, and the two first gears are engaged with the adjacent two racks.

[0010] Further, a avoiding position groove is opened on one side of the flying seat, and the second motor passes through the avoiding position groove and extends outwards.

[0011] Further, it further includes a pre-cooling and brittle fracture assembly. The pre-cooling and brittle fracture assembly includes an air compressor and a vortex tube fixed on one side of the fixed seat, a hollow ring body fixed inside the hollow groove, a flow channel opened inside the hollow ring body, a plurality of second nozzles annularly and arrayedly distributed on the inner wall of the hollow ring body and connected to the flow channel, and a second pipeline connecting the cold air discharging end of the vortex tube to the input end of the flow channel. The input end of the vortex tube is connected to the output end of the air compressor. The inner wall of the opening on one side of the hollow groove is fixed with a hollow guiding tube, and one side of the hollow ring body is fixed with a hollow guiding ring, and the hollow ring body is located between the hollow guiding tube and the hollow guiding ring.

[0012] Further, it further includes a pre-pressing treatment part. The pre-pressing treatment part includes a connecting frame fixed on one side of the flying seat, a first seat body fixed on one side of the connecting frame, a feeding groove opened inside the first seat body and two third movable grooves communicated with the feeding groove, two roller bodies respectively rotatably connected to the inner walls of the two third movable grooves, two pre-pressing flanges integrally formed on the outer surfaces of the two roller bodies, a third motor fixed on one side of the first seat body, and two second gears rotatably connected to the other side of the first seat body and meshing with each other. One ends of the two roller bodies are respectively fixed to the two second gears, and the output shaft of the third motor is fixed to the other end of one of the roller bodies.

[0013] Further, wire inlet guiding parts are fixed on both sides of the first seat body. The wire inlet guiding parts include two second seat bodies symmetrically fixed on one side of the first seat body, two guiding rollers respectively rotatably connected inside the two second seat bodies, and guiding grooves opened on the outer surfaces of the two guiding rollers.

[0014] Further, it further includes a micro-mist lubrication assembly, and the micro-mist lubrication assembly includes a liquid storage tank fixedly connected to one side of the flying seat, two pump bodies fixedly connected to one side of the liquid storage tank and with their input ends penetrating into the interior of the liquid storage tank, two groups of nozzles I fixedly connected to the inner wall of the hollow groove, and two pipelines I connecting the output ends of the two pump bodies to the input ends of the two groups of nozzles I.

[0015] A method for using a copper alloy wire shearing device includes the following steps: S1, control the third motor to work to drive a roller to rotate. The rotating roller drives another roller to rotate through the second gear. The rotation of the two rollers drives the rotation of the two preloading flanges. When the two preloading flanges contact the wire, preloading of the wire is achieved. The wire after preloading enters the hollow guide tube and the hollow groove through the guiding of the guiding roller. S2, when the copper alloy wire in S1 is fed into the hollow guide tube and the hollow groove, the wire passes through the hollow ring body. The air compressor works to input compressed gas into the vortex tube. The cold air end of the vortex tube discharges cold air. The cold air enters the flow channel in the hollow ring body through the second pipeline and finally is discharged from the nozzle II and blown onto the wire to pre-cool the wire. S3, control the first motor to work to drive the eccentric wheel to rotate. The rotation of the eccentric wheel drives the slider to move up and down in the chute. When the slider moves downward, it drives the pressure seat to descend, so that the lower end of the pressure seat contacts the upper end of the pressure column. The pressure seat applies a force to the pressure column to push the pressure column and the upper slide seat above to descend. The descent of the upper slide seat drives one group of racks to move downward. The movement of the racks drives the first gear to rotate. The first gear drives the other group of racks to move upward, so that the lower slide seat rises. The relative movement of the two slide seats drives the relative movement of the two shearing cutters. The relative movement of the two shearing cutters cuts the wire. S4, when the cutting action in S3 is completed, the pressure seat rises and separates from the pressure column. The spring pushes the two slide seats to reset. The second driving motor works to drive the lead screw to rotate. The rotation of the lead screw drives the movable seat and the shearing cutter to translate, changing the contact cutting area between the shearing cutter and the wire. S5, when the translation adjustment of the shearing cutter in S4 is completed and waiting for the next cutting, the pump body pumps the lubricating liquid in the liquid storage tank into the nozzle I through the pipeline I. The lubricating liquid is atomized and discharged from the nozzle I and sprayed on the surface of the shearing cutter.

[0016] Compared with the prior art, the beneficial effects of the present invention: (1) This solution is provided with a wear sharing part. When the shearing tool cuts the copper alloy wire, the second motor is controlled to work to drive the screw rod to rotate. The rotation of the screw rod can drive the movable seat to perform a translational motion in the second movable groove, thereby driving the shearing tool to translate, changing the area where the shearing tool contacts the copper alloy wire. After translation, the new cutting edge area participates in shearing, and the original high wear area can not participate in shearing and rest for cooling. The distribution of local friction hot spots (thermal spots) generated by high-frequency shearing will be more uniform, reducing coating degradation or tool-chip adhesion caused by overheating in a single area, thereby reducing the risks of tool sticking and thermal cracking. Since the wear is shared, the time to reach the tool change criterion (such as the maximum allowable grinding groove depth) is extended, the number of tool changes and the downtime maintenance cost can be reduced, and the service life of the tool can be extended.

[0017] (2) This solution is provided with a pre-cooling and brittle fracture component. By the cooperation of the air machine and the vortex tube, cold air can be output. The cold air discharged from the second nozzle can pre-cool the copper alloy wire, quickly reducing the wire temperature to close to or below room temperature. At low temperatures, the yield strength and hardness of the metal will both increase, and during shearing instantaneously, it can "brittlely fracture" rather than produce plastic extrusion. The end face burrs, hardened layers, and micro-drawing are significantly reduced. Pre-cooling can significantly reduce the tendency of tool-chip adhesion and improve the incision cleanliness. At the same time, the frictional heat generated by high-frequency shearing diffuses faster on the low-temperature substrate and is not easy to accumulate around the cutting edge, avoiding thermal deformation or tool sticking phenomena caused by local overheating. The surface hardness of the wire increases and the heat decreases, which can reduce the instantaneous impact and frictional wear borne by the tool, reduce the risk of tool coating failure at high temperatures, and improve the durability of the tool coating.

[0018] (3) This solution is provided with a pre-pressing treatment part. By driving the roller body to rotate, the pre-pressing flange on the outer surface of the roller can perform a slight pre-pressing treatment on the copper alloy wire, locally pre-pressing the outer surface of the wire before the shearing tool cuts the copper alloy wire. A tiny boss or groove is formed by pre-pressing, causing local plastic flow and cold working hardening of the metal in this area. When the cutting edge of the shear reaches, the cutting section has been pre-stratified, and the actual thickness of the metal cross-section to be sheared is reduced, the shearing force and instantaneous impact are weakened, and the incision is easier to be completely cut off. Since the cross-section to be cut is reduced by pre-pressing before the tangent point, the instantaneous cutting thickness is reduced, and the peak value of the maximum shearing force is reduced, thereby reducing the tool impact and the risk of micro-chipping, and extending the service life of the tool.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 to 8 , a copper alloy wire shearing device, including a fixed seat 1, a driving component connected to the fixed seat 1, and a moving part 2 connected to the driving component; The moving part 2 includes a flying seat 21, a hollow groove 22 opened inside the flying seat 21, and a shearing component 3 connected inside the flying seat 21; The shearing assembly 3 includes a first movable groove 31 formed inside the flying seat 21, two sliding seats 32 symmetrically slidably connected to the inner wall of the first movable groove 31, two wear sharing parts 4 respectively connected inside the two sliding seats 32, a pressing column 35 fixedly connected to one side of one of the sliding seats 32 and extending outwards through the flying seat 21, a reset part connected inside the first movable groove 31 to reset the sliding seat 32, and a transmission part connected inside the first movable groove 31 to drive the two sliding seats 32 to move relatively; The wear sharing part 4 includes a second movable groove 42 formed inside the sliding seat 32, a movable seat 33 slidably connected in the second movable groove 42, a lead screw 43 rotatably connected in the second movable groove 42 and screwed inside the movable seat 33, a shearing tool 34 fixedly connected to one side of the movable seat 33, and a second motor 41 with an output shaft connected to the lead screw 43 fixedly connected to one side of each of the two sliding seats 32.

[0023] The driving assembly includes two slide rails 11 fixedly connected to one side of the fixed seat 1, a movable plate 12 slidably connected to the slide rails 11, a chute 15 formed inside the movable plate 12, a slider 16 slidably connected in the chute 15, a pressing seat 17 fixedly connected to one side of the slider 16, an eccentric wheel 14 rotatably connected to one side of the fixed seat 1 and rotatably connected to one side of the slider 16, and a first motor 13 fixedly connected to the other side of the fixed seat 1 and with an output shaft fixedly connected to the eccentric wheel 14. The flying seat 21 is fixedly connected to one side of the movable plate 12.

[0024] The reset part includes a plurality of guide posts 36 with both ends fixedly connected to the inner wall of the first movable groove 31, a spring 37 sleeved outside the guide posts 36. Both of the two sliding seats 32 are movably sleeved outside the guide posts 36, and both ends of the spring 37 are respectively connected to the sliding seat 32 and the inner wall of the first movable groove 31.

[0025] The transmission part includes two groups of racks 38 respectively fixedly connected to both sides of the two sliding seats 32, and two first gears 39 rotatably connected inside the flying seat 21, and the two first gears 39 are meshed with the adjacent two racks 38.

[0026] A clearance groove 24 is formed on one side of the flying seat 21, and the second motor 41 passes through the clearance groove 24 and extends outwards.

[0027] By adopting the above technical solution, the copper alloy wire enters the hollow groove 22. The first motor 13 operates to drive the eccentric wheel 14 to rotate. The rotation of the eccentric wheel 14 drives the slider 16 to move up and down in the chute 15. At the same time, the rotation of the eccentric wheel 14 can also make the movable plate 12 move left and right along the slide rail 11. The purpose of the movable plate 12 moving left and right is to be able to move at the same speed as the wire. At the same time, when the slider 16 moves downward, it drives the pressure seat 17 to descend, so that the lower end of the pressure seat 17 contacts the upper end of the pressure column 35. The pressure seat 17 applies a force to the pressure column 35 to push the pressure column 35 and the upper slide seat 32 above to descend. The descent of the upper slide seat 32 drives one set of racks 38 to move downward. The movement of the rack 38 drives the first gear 39 to rotate. The first gear 39 drives the other set of racks 38 to move upward, causing the lower slide seat 32 to rise. The spring 37 is compressed. The relative movement of the two slide seats 32 drives the relative movement of the two shearing cutters 34. The relative movement of the two shearing cutters 34 cuts the wire. When approaching the moving speed of the wire, the instantaneous resultant force of the two blades cuts off to complete the flying shear action. After the cutting action is completed, the pressure seat 17 rises and separates from the pressure column 35. The spring 37 pushes the two slide seats 32 to reset. The second driving motor 41 operates to drive the lead screw 43 to rotate. The rotation of the lead screw 43 drives the movable seat 33 and the shearing cutter 34 to translate, changing the contact cutting area between the shearing cutter 34 and the wire. After translation, the new cutting edge area participates in shearing, and the original high-wear area can not participate in shearing and rest for cooling. The distribution of local friction hot spots (hot spots) generated by high-frequency shearing will be more uniform, reducing coating degradation or tool chip adhesion caused by overheating in a single area, thereby reducing the risk of tool sticking and thermal cracking. Since the wear is shared, the time to reach the tool change criterion (such as the maximum allowable grinding groove depth) is extended, the number of tool changes and the downtime maintenance cost can be reduced, and the service life of the tool can be extended.

[0028] As Figure 3 and Figure 6 shown, it further includes a pre-cooling brittle fracture assembly 6. The pre-cooling brittle fracture assembly 6 includes an air compressor 61 and a vortex tube 62 fixedly connected to one side of the fixed seat 1, a hollow ring body 64 fixedly connected inside the hollow groove 22, a flow channel opened inside the hollow ring body 64, a plurality of second nozzles 65 annularly and arrayedly distributed on the inner wall of the hollow ring body 64 and connected to the flow channel, and a second pipeline 63 connecting the cold air discharge end of the vortex tube 62 to the input end of the flow channel. The input end of the vortex tube 62 is connected to the output end of the air compressor 61. A hollow guiding tube 23 is fixedly connected to the inner wall of one side opening of the hollow groove 22. A hollow guiding ring 66 is fixedly connected to one side of the hollow ring body 64, and the hollow ring body 64 is located between the hollow guiding tube 23 and the hollow guiding ring 66.

[0029] By adopting the above technical solution, when the copper alloy wire is fed into the hollow guide tube 23 and the hollow groove 22, the wire will pass through the hollow ring body 64. The air compressor 61 operates to input compressed gas into the vortex tube 62. The cold air end of the vortex tube 62 discharges cold air. The cold air enters the flow channel in the hollow ring body 64 from the second pipeline 63, and finally is discharged from the second nozzle 65 to blow on the wire to pre-cool the wire, quickly reducing the wire temperature to near or below room temperature. At low temperatures, the yield strength and hardness of the metal will increase, and it is more likely to "fracture brittlely" rather than produce plastic extrusion during instantaneous shearing. The end face burrs, hardened layers, and micro-drawing are significantly reduced. Pre-cooling can significantly reduce the tendency of chip adhesion and improve the incision cleanliness. At the same time, the frictional heat generated by high-frequency shearing diffuses faster on the low-temperature substrate and is not easily accumulated around the cutting edge, avoiding thermal deformation or tool sticking caused by local overheating. The surface hardness of the wire increases and the heat decreases, which can reduce the instantaneous impact and frictional wear borne by the tool, reduce the risk of tool coating failure at high temperatures, and improve the durability of the tool coating.

[0030] As Figure 7 shown, it further includes a pre-pressing treatment part 7, and the pre-pressing treatment part 7 includes a connecting frame 72 fixedly connected to one side of the flying seat 21, a first seat body 71 fixedly connected to one side of the connecting frame 72, a feeding groove 78 opened inside the first seat body 71, two movable grooves three 73 communicated with the feeding groove 78, two roller bodies 75 respectively rotatably connected to the inner walls of the two movable grooves three 73, two pre-pressing flanges 76 integrally formed on the outer surfaces of the two roller bodies 75, a third motor 74 fixedly connected to one side of the first seat body 71, and two second gears 77 rotatably connected to the other side of the first seat body 71 and meshing with each other. One ends of the two roller bodies 75 are respectively fixedly connected to the two second gears 77, and the output shaft of the third motor 74 is fixedly connected to the other end of one of the roller bodies 75.

[0031] Both sides of the first seat body 71 are fixedly connected with wire inlet guiding parts 8, and the wire inlet guiding parts 8 include two second seat bodies 81 symmetrically fixedly connected to one side of the first seat body 71, two guiding rollers 82 respectively rotatably connected to the interiors of the two second seat bodies 81, and guiding grooves 83 opened on the outer surfaces of the two guiding rollers 82.

[0032] By adopting the above technical solution, the motor three 74 operates to drive a roller 75 to rotate. The rotating roller 75 drives another roller 75 to rotate through the second gear 77. The rotation of the two rollers 75 drives the rotation of the two preloading flanges 76. When the two preloading flanges 76 contact the silk thread, preloading of the silk thread is achieved. The preloaded silk thread is guided by the guide roller 82 and then enters the hollow guide tube 23 and the hollow groove 22. Before the copper alloy silk thread is cut by the shearing tool 34, local preloading is performed on the outer surface of the silk thread to form a tiny boss or groove, causing local plastic flow and cold working hardening of the metal in this area. When the shearing edge arrives, the cutting section has been pre-stratified, the thickness of the metal cross-section that actually needs to be sheared is reduced, the shearing force and instantaneous impact are weakened, and the incision is easier to be cut off. Since the cross-section to be sheared is reduced by preloading before the tangent point, the instantaneous cutting thickness is reduced, the peak value of the maximum shearing force is reduced, thereby reducing the tool impact and the risk of micro-edge chipping, and prolonging the service life of the tool. It should be noted here that the preloading step can be synchronized with the shearing assembly 3 of the flying shear to ensure that a slight preloading treatment (the preloading depth is about 1-2% of the wire diameter, and the height of the preloading flange 76 can also be adjusted according to the actual situation to change the preloading depth) is performed every N meters (or every N cuts).

[0033] As Figure 3 and Figure 5 shown, it further includes a micro-mist lubrication assembly 5, and the micro-mist lubrication assembly 5 includes a liquid storage tank 51 fixedly connected to one side of the flying seat 21, two pump bodies 52 fixedly connected to one side of the liquid storage tank 51 and with their input ends penetrating into the inside of the liquid storage tank 51, two groups of first nozzles 54 fixedly connected to the inner wall of the hollow groove 22, and two pipelines 53 connecting the output ends of the two pump bodies 52 to the input ends of the two groups of first nozzles 54.

[0034] By adopting the above technical solution, when the translation adjustment of the shearing tool 34 is completed and waiting for the next cut, the pump body 52 pumps the lubricating liquid in the liquid storage tank 51 into the first nozzle 54 through the pipeline 53. The lubricating liquid is atomized and discharged from the first nozzle 54 and sprayed on the surface of the shearing tool 34. The lubricating liquid can be a semi-synthetic coolant containing extreme pressure additives (such as sulfur-phosphorus compounds) to improve lubricity and form a protective film in the high-pressure area. The extreme pressure additives such as sulfur and phosphorus react under high pressure and high temperature to generate a thin and tough chemical adsorption film, which can withstand the shearing stress at the interface between the cutting edge and the workpiece, prevent micro-welding adhesion and scuffing wear between metals. At the same time, the partial frictional heat on the surface of the cutting edge can also be carried away through fine atomization and micro-lubrication, avoiding local softening of the tool coating and thermal fatigue of the substrate. The impact heat and stress borne by the tool drop suddenly, and the service life of the shearing tool 34 is prolonged.

[0035] Usage method: S1. Control the operation of motor three 74 to drive a roller 75 to rotate. The rotating roller 75 drives another roller 75 to rotate through gear two 77. The rotation of the two rollers 75 drives the rotation of two preloading flanges 76. When the two preloading flanges 76 come into contact with the silk thread, preloading of the silk thread is achieved. The silk thread after preloading is guided by guide roller 82 and then enters hollow guide tube 23 and hollow groove 22; S2. When the copper alloy silk thread is fed into hollow guide tube 23 and hollow groove 22 in S1, the silk thread passes through hollow ring body 64. The air compressor 61 operates to input compressed gas into vortex tube 62. The cold air end of vortex tube 62 discharges cold air. The cold air enters the flow channel in hollow ring body 64 through pipe two 63 and finally is discharged from spray head two 65 to blow on the silk thread to pre-cool the silk thread; S3. Control the operation of motor one 13 to drive eccentric wheel 14 to rotate. The rotation of eccentric wheel 14 drives slider 16 to move up and down in chute 15. When the sliding seat 32 moves downward, it drives pressure seat 17 to descend, so that the lower end of pressure seat 17 contacts the upper end of pressure column 35. Pressure seat 17 applies a force to pressure column 35 to push pressure column 35 and the upper sliding seat 32 above to descend. The descent of the upper sliding seat 32 drives one set of rack 38 to move downward. The movement of rack 38 drives gear one 39 to rotate. Gear one 39 drives the other set of rack 38 to move upward, causing the lower sliding seat 32 to rise. The relative movement of the two sliding seats 32 drives the relative movement of the two cutting tools 34. The relative movement of the two cutting tools 34 cuts the silk thread; S4. After the cutting action in S3 is completed, pressure seat 17 rises and separates from pressure column 35. Spring 37 pushes the two sliding seats 32 to reset. The driving motor two 41 operates to drive lead screw 43 to rotate. The rotation of lead screw 43 drives movable seat 33 and cutting tool 34 to translate, changing the contact cutting area between cutting tool 34 and the silk thread; S5. When the translation adjustment of cutting tool 34 in S4 is completed and waiting for the next cutting, pump body 52 pumps the lubricating liquid in liquid storage tank 51 into spray head one 54 through pipe one 53. The lubricating liquid is atomized and discharged from spray head one 54 and sprayed on the surface of cutting tool 34.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitution or change, and should be covered by the protection scope of the present invention.

10. A method for using a copper alloy wire shearing device, which uses the copper alloy wire shearing device described in claim 9 above, characterized in that, It includes the following steps: S1, control the third motor (74) to work to drive one roller body (75) to rotate. The rotating roller body (75) drives the other roller body (75) to rotate through the second gear (77). The two roller bodies (75) rotate to drive the two pre-pressing flanges (76) to rotate. When the two pre-pressing flanges (76) contact the wire, pre-pressing of the wire is realized. The wire after pre-pressing enters the hollow guiding tube (23) and the hollow groove (22) through the guiding of the guiding roller (82). S2. When the copper alloy wire in S1 is fed into the hollow guide tube (23) and the hollow groove (22), the wire passes through the hollow ring body (64). The air compressor (61) operates to input compressed gas into the vortex tube (62). The cold air end of the vortex tube (62) discharges cold air, which enters the flow passage in the hollow ring body (64) through the second pipe (63), and finally discharges from the second nozzle (65) and blows towards the wire to pre-cool the wire. S3. Control the first motor (13) to operate and drive the eccentric wheel (14) to rotate. The rotation of the eccentric wheel (14) drives the slider (16) to move up and down in the chute (15). When the slider (16) moves downward, it drives the pressure seat (17) to descend, so that the lower end of the pressure seat (17) contacts the upper end of the pressure column (35). The pressure seat (17) applies a force to the pressure column (35) to push the pressure column (35) and the upper slide seat (32) above to descend. The descent of the upper slide seat (32) drives one set of racks (38) to move downward. The movement of the rack (38) drives the first gear (39) to rotate, and the first gear (39) drives the other set of racks (38) to move upward, causing the lower slide seat (32) to rise. The relative movement of the two slide seats (32) drives the relative movement of the two cutting tools (34), and the relative movement of the two cutting tools (34) cuts the wire. S4. After the cutting action in S3 is completed, the pressure seat (17) rises and separates from the pressure column (35). The spring (37) pushes the two slide seats (32) to reset. The second drive motor (41) operates to drive the lead screw (43) to rotate. The rotation of the lead screw (43) drives the movable seat (33) and the cutting tool (34) to translate, changing the contact cutting area between the cutting tool (34) and the wire. S5. When the translation adjustment of the cutting tool (34) in S4 is completed and waiting for the next cutting, the pump body (52) pumps the lubricating fluid in the liquid storage tank (51) into the first nozzle (54) through the first pipe (53). The lubricating fluid atomizes and discharges from the first nozzle (54) and sprays on the surface of the cutting tool (34).
