Description

Technical Field

[0001] The present invention relates to the field of copper wire cutting, and more particularly to a copper alloy wire shearing device and a method for using the same. Background Art

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

[0003] After wire drawing, annealing and other processes, copper alloy wire needs to be sheared. Currently, there are many ways to shear copper alloy wire, including mechanical shearing, ultrasonic / laser cutting, and wire EDM. Mechanical shearing has the advantages of mature equipment, fast speed, and easy integration with automated production lines. Therefore, it is the most commonly used shearing method on the production line. Flying shears are a type of mechanical shearing method. The scissor blades used in flying shears move at the same speed as the wire. When the blade movement speed is close to the wire movement speed, the two blades instantly work together to cut the wire, and the wire is continuously fed out. The production line does not need to stop due to shearing. Since the flying shear production line runs at high speed and will not stop, under high-frequency shearing, the alloy or coated blades are gradually blunted under high temperature and high pressure impact, and the blade gap increases, which will cause the incision quality to deteriorate. When the wear is severe, it may even cause chipping, causing the blade to pierce the wire, causing the wire to break and twist. Summary of the Invention

[0004] In view of the problems existing in the prior art, the object of the present invention is to provide a copper alloy wire shearing device and a method for using the same.

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

[0012] Furthermore, the transmission part includes two sets of racks respectively fixed on both sides of the two slides, two gears 1 rotatably connected inside the flying seat, and the two gears 1 are meshed with two adjacent racks.

[0013] Furthermore, a avoidance groove is provided on one side of the flying seat, and the second motor passes through the avoidance groove and extends outward.

[0014] Furthermore, it also includes a pre-cooling brittle fracture component, which includes an air compressor and a vortex tube fixedly connected to one side of the fixed seat, a hollow ring body fixedly connected to the inside of the hollow groove, a flow channel opened inside the hollow ring body, a plurality of nozzles distributed in a circular array on the inner wall of the hollow ring body and connected to the flow channel, and a pipe connecting the cold discharge end of the vortex tube with the input end of the flow channel.

[0016] Furthermore, both sides of the seat body are fixed with a wire feed guide part, and the wire feed guide part includes two seat bodies symmetrically fixed on one side of the seat body, two guide rollers rotatably connected to the inside of the two seat bodies, and guide grooves opened on the outer surfaces of the two guide rollers.

[0017] Furthermore, it also includes a micro-mist lubrication component, and the micro-mist lubrication component 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 input ends passing through the interior of the liquid storage tank, two groups of nozzles fixedly connected to the inner wall of the hollow groove, and two pipes connecting the output ends of the two pump bodies with the input ends of the two groups of nozzles.

[0018] A method for using a copper alloy wire shearing device comprises the following steps:

[0019] S1, controls motor 3 to drive one roller to rotate, and the rotating roller drives another roller to rotate through gear 2. The rotation of the two rollers drives the two pre-stressing flanges to rotate. When the two pre-stressing flanges come into contact with the wire, the wire is pre-stressed. The pre-stressed wire is guided by the guide roller and enters the hollow guide tube and the hollow groove;

[0020] In S2, when the copper alloy wire in S1 is fed into the hollow guide tube and the hollow groove, the wire will pass through the hollow ring body. The air compressor will input compressed gas into the vortex tube. The cold air end of the vortex tube will discharge cold air. The cold air will enter the flow channel in the hollow ring body from the second pipe and finally be discharged from the second nozzle to blow towards the wire to pre-cool the wire.

[0021] S3, control motor 1 to work and drive the eccentric wheel to rotate, the rotation of the eccentric wheel drives the slider to move up and down in the slide, and 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, and the pressure seat applies a force to the pressure column to push the pressure column and the upper slide to descend, and the descent of the upper slide drives one set of racks to move downward, and the movement of the rack drives gear 1 to rotate, and gear 1 drives the other set of racks to move upward, so that the lower slide rises, and the relative movement of the two slides drives the relative movement of the two shearing tools, and the relative movement of the two shearing tools cuts the wire;

[0022] S4, when the cutting action in S3 is completed, the pressure seat rises and separates from the pressure column, the spring pushes the two slides to reset, the drive motor 2 works to drive the screw to rotate, and the rotation of the screw drives the movable seat and the shearing tool to move horizontally, changing the contact cutting area between the shearing tool and the wire;

[0023] S5, when the shearing tool translation adjustment 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 one through the pipe one, and the lubricating liquid is atomized and discharged from the nozzle one and sprayed on the surface of the shearing tool.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] (1) This solution is provided with a wear sharing part. When the shearing tool cuts the copper alloy wire, the control motor 2 drives the screw to rotate. The rotation of the screw can drive the movable seat to translate in the movable groove 2, thereby driving the shearing tool to translate, changing the area where the shearing tool contacts the copper alloy wire. After translation, the new blade area participates in shearing, and the original high wear area can be non-participated in shearing and rest for cooling. The local friction hot spots (hot spots) generated by high-frequency shearing will be more evenly distributed, reducing the 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, which can reduce the number of tool changes and downtime maintenance costs, and extend the service life of the tool.

[0026] (2) This scheme is equipped with a pre-cooling brittle fracture component, which can output cold air through the cooperation of the air machine and the vortex tube. The cold air discharged from the second nozzle can pre-cool the copper alloy wire, and quickly reduce the wire temperature to close to or below room temperature. The yield strength and hardness of the metal will increase at low temperatures, and the shearing instant will be more "brittle fracture" rather than plastic pultrusion. The end face burrs, hardened layer and micro-drawing are greatly reduced. Pre-cooling can significantly reduce the tendency of tool chips to adhere and improve the cleanliness of the incision. At the same time, the friction heat generated by high-frequency shearing diffuses faster on the low-temperature substrate and is not easy to accumulate around the blade, avoiding thermal deformation or sticking caused by local overheating. The surface hardness of the wire is improved and the heat is reduced, which can reduce the instantaneous impact and friction wear of the tool, reduce the risk of tool coating failure at high temperature, and improve the durability of the tool coating.

[0027] (3) This solution is provided with a pre-stressing treatment part. By driving the roller body to rotate, the pre-stressing flange on the outer surface of the roller body can perform a slight pre-stressing treatment on the copper alloy wire. Before the shearing tool cuts the copper alloy wire, the outer surface of the wire is locally pre-stressed. The pre-stressing forms a tiny boss or groove, which causes the metal to produce local plastic flow and cold hardening in this area. When the shearing blade arrives, the cutting section has been pre-stratified, the actual thickness of the metal section that needs to be sheared is reduced, the shear force and instantaneous impact are weakened, and the incision is easier to be cut cleanly. Since the section to be cut is reduced by pre-stressing before the cutting point, the instantaneous cutting thickness is reduced, and the maximum shear force peak is reduced, thereby reducing the tool impact, reducing the risk of micro-chipping, and extending the tool life.

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only 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 ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0039] See also Figures 1 to 8 A copper alloy wire shearing device includes a fixing base 1, a driving assembly connected to the fixing base 1, and a moving part 2 connected to the driving assembly;

[0040] The following portion 2 includes a flying seat 21, a hollow groove 22 provided inside the flying seat 21, and a shearing assembly 3 connected to the inside of the flying seat 21;

[0041] The shearing assembly 3 includes a movable groove 31 provided inside the flying seat 21, two slides 32 symmetrically slidably connected to the inner wall of the movable groove 31, two wear sharing parts 4 respectively connected to the two slides 32, a pressure column 35 fixed to one side of one of the slides 32 and extending outward through the flying seat 21, a reset part connected to the movable groove 31 for resetting the slide 32, and a transmission part connected to the movable groove 31 to drive the two slides 32 to move relative to each other;

[0042] The wear sharing part 4 includes a movable groove 2 42 opened inside the slide 32, a movable seat 33 slidingly connected in the movable groove 2 42, a screw rod 43 rotatably connected in the movable groove 2 42 and screwed in the movable seat 33, and a shearing tool 34 fixed to one side of the movable seat 33. One side of each of the two slides 32 is fixed with a motor 2 41 whose output shaft is connected to the screw rod 43.

[0043] The driving assembly includes two slide rails 11 fixedly connected to one side of the fixed seat 1, a movable plate 12 slidingly connected to the slide rails 11, a slide groove 15 opened inside the movable plate 12, a slider 16 slidingly connected in the slide groove 15, a pressure 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, a motor 13 fixedly connected to the other side of the fixed seat 1 and with the output shaft fixedly connected to the eccentric wheel 14, and the flying seat 21 fixedly connected to one side of the movable plate 12.

[0044] The reset portion includes a plurality of guide posts 36 whose ends are fixedly connected to the inner wall of the movable groove 31, and a spring 37 sleeved on the outside of the guide posts 36. The two slides 32 are movably sleeved on the outside of the guide posts 36, and the two ends of the spring 37 are respectively connected to the slide 32 and the inner wall of the movable groove 31.

[0045] The transmission part includes two sets of racks 38 fixed to both sides of the two slides 32, and two gears 39 rotatably connected to the inside of the flying seat 21, and the two gears 39 are engaged with the two adjacent racks 38.

[0046] 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 outward.

[0047] By adopting the above technical solution, the copper alloy wire enters the hollow groove 22, the motor 13 works to drive the eccentric wheel 14 to rotate, and the rotation of the eccentric wheel 14 drives the slider 16 to move up and down in the slide groove 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 movable plate 12 moves left and right in order 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, and the pressure seat 17 applies a force to the pressure column 35 to push the pressure column 35 and the upper slide 32 to descend. The descent of the upper slide 32 drives one group of racks 38 to move downward, and the rack 38 moves to drive the gear 1 39 to rotate, and the gear 1 39 drives the other group of racks 38 to move upward, so that the lower slide 32 rises, and the spring 37 is squeezed. The relative movement of the two slides 32 drives the two shearing tools 34 to move relative to each other. The cutting tool 34 moves relative to each other to cut the wire. When it is close to the moving speed of the wire, the two blades instantly work together to cut and complete the flying shearing action. After the cutting action is completed, the pressure seat 17 rises and separates from the pressure column 35, and the spring 37 pushes the two slides 32 to reset. The drive motor 2 41 works to drive the screw rod 43 to rotate. The rotation of the screw rod 43 drives the movable seat 33 and the shearing tool 34 to move horizontally, changing the contact cutting area between the shearing tool 34 and the wire. After translation, the new blade area participates in shearing, and the original high wear area can not participate in shearing and rest for cooling. The local friction hot spots (hot spots) generated by high-frequency shearing will be more evenly distributed, reducing coating degradation or chip adhesion caused by overheating in a single area, thereby reducing the risk of tool sticking and thermal cracking. Since the wear is distributed, the time to reach the tool change criterion (such as the maximum allowable grinding groove depth) is extended, which can reduce the number of tool changes and downtime maintenance costs, and extend the service life of the tool.

[0048] like Figure 3 and Figure 6 As shown, it also includes a pre-cooling brittle fracture component 6, which 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 to the inside of the hollow groove 22, a flow channel opened inside the hollow ring body 64, a plurality of nozzles 2 65 distributed in a ring array on the inner wall of the hollow ring body 64 and connected to the flow channel, and a pipe 2 63 connecting the cold discharge end of the vortex tube 62 with 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, and a hollow guide tube 23 is fixedly connected to the inner wall of the opening on one side of the hollow groove 22, and a hollow guide 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 guide tube 23 and the hollow guide ring 66.

[0049] 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, and the air compressor 61 will input compressed gas into the vortex tube 62. The cold air end of the vortex tube 62 discharges cold air, and the cold air enters the flow channel in the hollow ring body 64 from the pipe 2 63, and is finally discharged from the nozzle 2 65 to blow towards the wire to pre-cool the wire, so that the wire temperature is quickly reduced to near or below room temperature. At low temperatures, the yield strength and hardness of the metal will increase, and shearing will be more likely to "fracture brittlely" rather than produce plastic pultrusion. The end face burrs, hardened layer and micro-drawing are greatly reduced. Pre-cooling can significantly reduce the tendency of tool chips to adhere, and improve the cleanliness of the incision. At the same time, the friction heat generated by high-frequency shearing diffuses faster on the low-temperature substrate and is not easy to accumulate around the blade, avoiding thermal deformation or tool sticking caused by local overheating. The surface hardness of the wire is improved and the heat is reduced, which can reduce the instantaneous impact and friction wear of the tool, reduce the risk of tool coating failure at high temperatures, and improve the durability of the tool coating.

[0050] like Figure 7 As shown, it also includes a pre-stressing processing part 7, and the pre-stressing processing part 7 includes a connecting frame 72 fixedly connected to one side of the flying seat 21, a seat body 71 fixedly connected to one side of the connecting frame 72, a feed trough 78 opened inside the seat body 71 and two movable troughs 3 73 connected to the feed trough 78, two roller bodies 75 rotatably connected to the inner walls of the two movable troughs 3 73, two pre-stressing flanges 76 integrally formed on the outer surfaces of the two roller bodies 75, a motor 3 74 fixedly connected to one side of the seat body 71, and two gears 2 77 rotatably connected to the other side of the seat body 71 and meshing with each other, one end of the two roller bodies 75 are respectively fixedly connected to the two gears 2 77, and the output shaft of the motor 3 74 is fixedly connected to the other end of one of the roller bodies 75.

[0051] The two sides of the seat body 1 71 are fixed with an inlet guide part 8, and the inlet guide part 8 includes two seat bodies 2 81 symmetrically fixed on one side of the seat body 1 71, two guide rollers 82 rotatably connected to the inside of the two seat bodies 2 81, and guide grooves 83 opened on the outer surfaces of the two guide rollers 82.

[0052] By adopting the above technical solution, the motor 3 74 drives a roller 75 to rotate, and the rotating roller 75 drives another roller 75 to rotate through the gear 2 77. The rotation of the two rollers 75 drives the two pre-stressing flanges 76 to rotate. When the two pre-stressing flanges 76 come into contact with the wire, the pre-stressing of the wire is achieved. The pre-stressed wire is guided by the guide roller 82 and enters the hollow guide tube 23 and the hollow groove 22. Before the shearing tool 34 cuts the copper alloy wire, the outer surface of the wire is locally pre-stressed. The pre-stressing forms a tiny boss or groove, causing the metal to produce local plastic flow and cold hardening in this area. When the shearing blade arrives, The cutting section has been pre-layered, the actual thickness of the metal section that needs to be sheared is reduced, the shear force and instantaneous impact are weakened, and the incision is easier to cut. Since the section to be sheared is reduced by pre-pressing before the cutting point, the instantaneous cutting thickness is reduced, and the maximum shear force peak is reduced, thereby reducing the tool impact, reducing the risk of micro-chipping, and extending the tool life. It should be noted here that the pre-pressing step can be synchronized with the shearing component 3 of the flying shear to ensure that a slight pre-pressing treatment is performed every N meters (or every N cuts) (the pre-pressing depth is about 1-2% of the wire diameter, and the height of the pre-pressing flange 76 can also be adjusted according to actual conditions to change the pre-pressing depth).

[0053] like Figure 3 and Figure 5 As shown, it also includes a micro-mist lubrication component 5, and the micro-mist lubrication component 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 input ends passing through the interior of the liquid storage tank 51, two groups of nozzles 54 fixedly connected to the inner wall of the hollow groove 22, and two pipes 53 connecting the output ends of the two pump bodies 52 and the input ends of the two groups of nozzles 54.

[0054] By adopting the above technical solution, when the shearing tool 34 completes the translation adjustment and waits for the next cutting, the pump body 52 pumps the lubricating liquid in the liquid storage tank 51 into the nozzle 54 through the pipe 53, and the lubricating liquid is atomized and discharged from the 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 and phosphorus compounds) to improve the lubricity and form a protective film in the high-pressure area. Extreme pressure additives such as sulfur and phosphorus react under high pressure and high temperature to form a thin and strong chemical adsorption film, which can withstand shear stress at the interface between the blade and the workpiece, prevent micro-welding adhesion and adhesive wear between metals, and at the same time, through fine atomization and micro-lubrication, it can also take away part of the friction heat on the blade surface, avoid local softening of the tool coating and thermal fatigue of the matrix, and avoid the impact heat and stress sudden drop on the tool, thereby extending the service life of the shearing tool 34.
