[0034] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0035] refer to Figures 1 to 10 :
[0036] A conductor with low cost and high conductivity, the conductor is composed of an inner core, an inner supporting layer and an outer covering layer in sequence from inside to outside, the inner supporting layer is formed by twisting a plurality of metal wires, and the outer covering layer is formed by twisting a plurality of copper wires.
[0037] The cross sections of the metal wire and the copper wire in the cross section of the conductor are all irregularly shaped, and all the irregular shapes together constitute a circular cross section of the conductor.
[0038] The cross sections of the metal wire and the copper wire in the cross section of the conductor are both circular, and all circles together constitute the circular cross section of the conductor.
[0039] It should be noted that the inner core of the conductor can be an insulator, steel, iron or other metal, the metal wire of the inner support layer is aluminum or aluminum alloy single wire, and the outer covering layer is copper single wire. 2 The cable has 14 aluminum or aluminum alloy wires inside and 9 copper wires outside. 2 The number of aluminum or aluminum alloy single wires inside the cable is 30, and the number of copper single wires outside is 18. The conductor in the present invention adopts a combination of copper + aluminum or aluminum alloy (copper outside and aluminum or aluminum alloy inside) to save 20%-40% of the cost, and can make the cable more conductive, lightweight, and have enhanced flexibility and is not easy to break. It can also reduce the difficulty of construction, be safer, have tight twisting, overall density, optimal conduction, and are not easy to form eddy currents.
[0040] A conductor processing device with low cost and high conductivity, comprising a wire drawing die, a busbar storage device, a machine base 1, a stranding die 17 and a traction device arranged in sequence, and also comprising a support plate 2 rotatably arranged on the machine base 1, a plurality of bearing support plates 3 fixedly arranged on the support plate 2 in an annular shape, and a limiting bracket 4 (such as Figure 6 As shown in the figure), a wire storage wheel 5 rotatably arranged on each limiting bracket 4, a damper 7 fixedly arranged on each limiting bracket 4 and connected to the rotating shaft of the wire storage wheel 5, a bearing branch pipe 8 fixedly arranged on the side of the support plate 2 away from the bearing support plate 3, a supporting bracket 11 fixedly arranged in front of the machine base 1, a bearing ring 12 rotatably arranged on the supporting bracket 11, a wire management branch pipe 13 fixedly arranged on the bearing ring 12, a bearing disc 14 coaxially fixedly arranged on the wire management branch pipe 13, and a wire management ring 16 fixedly arranged at the end of the wire management branch pipe 13 , a stranding die 17 fixedly arranged on one end of the wire management branch pipe 13 near the wire management ring 16, a tension detection mechanism for detecting the tension of the sub-wire 10 and a correction unit for correcting the tension of the sub-wire 10, the detection mechanism includes a plurality of detection output ends arranged in a ring shape on the supporting disc 14, the correction unit includes a transmission mechanism and a brake mechanism arranged on each supporting plate 3, the brake mechanism has a deceleration output end, the detection output end is connected to the deceleration output end through the transmission mechanism, and the wire storage wheel 5 is used to store the sub-wire 10 after being shaped by the wire drawing die.
[0041] It should be noted that the sub-wire 10 is copper, aluminum or aluminum alloy, and the specific structure of the cable is aluminum or aluminum alloy inside and copper on the outermost layer. The copper wire, aluminum or aluminum alloy wire passes through the wire drawing die. After drawing, its cross section becomes irregular or circular. The busbar storage device, the stranding die 17 and the traction device are mature existing technologies and will not be repeated here. It should also be noted that when the cable is not fully loaded, only the outer layer has current, and the inner layer hardly has current. No matter what the purpose is, it is impossible to reach full load operation, that is, only the copper layer is energized, and the aluminum or aluminum alloy part is idle. Thereby reducing the waste of precious copper resources. Only when the equipment is started, it is possible for a single cable to reach full load instantly, that is, the inner core aluminum is energized instantly. Even at full load, the conductor of the present invention fully meets normal use, and its service life is equivalent to that of a copper conductor.
[0042] The invention fully meets the current national standard for the number, resistance, outer diameter, twisting structure, twisting direction and twisting pitch of copper conductors and is used as a new type of conductor for use in electric wires and cables instead of copper conductors.
[0043] When the equipment is working, the busbar storage device temporarily stores the wire after drawing (the busbar 9 is made of aluminum, aluminum alloy or other metals such as iron, which is adjusted according to production needs), and the storage wheel 5 stores the sub-wires 10 (the sub-wires 10 are copper, aluminum or aluminum alloy) that have also been drawn. Then, the busbar 9 and several sub-wires 10 are stretched out and passed through the stranding die 17, and then pulled and reeled by the traction device. After that, the support disk 2 rotates on the machine base 1 (it should be noted that a rotating drive device is provided on the machine base 1, and this device can be a motor, and its purpose is only to drive the support disk 2 to rotate). The rotation of the support disk 2 drives all the storage wheels 5 to rotate, and cooperates with the pulling of the traction device to make the sub-wires 10 spirally wound around the busbar 9.
[0044] When the wire is twisted, the detection output end of the tension detection mechanism is always in contact with the sub-wire 10 (it should be noted that, according to production needs, several detection output ends and several wire storage wheels 5 are set corresponding to the number of sub-wires 10 required). When a certain sub-wire 10 becomes loose, the detection output end responds immediately, and drives the brake mechanism to operate through the transmission mechanism. The operation of the brake mechanism then decelerates the rotating shaft of the wire storage wheel 5 through the deceleration output end, causing the sub-wire 10 to be tightened again, thereby facilitating the normal twisting process.
[0045] In order to show the detailed structure of the tension detection mechanism, the following features are also set:
[0046] The tension detection mechanism also includes a plurality of annular receiving slots 15 (such as Figure 4As shown), a sliding support plate 18 slidingly arranged in each accommodating slide groove 15, a wheel frame 20 fixedly arranged on each sliding support plate 18, a clamping roller 21 rotatably arranged on each wheel frame 20, and a pressure spring 19 arranged on the side of each sliding support plate 18 away from the wheel frame 20, the clamping roller 21 is against the sub-line 10, one end of the pressure spring 19 is fixedly connected to the sliding support plate 18, and the other end is fixedly connected to the groove wall of the accommodating slide groove 15.
[0047] The sliding support plate 18 is the detection output end of the tension detection mechanism.
[0048] It should be noted that during normal operation, the sub-line 10 is taut, and the taut sub-line 10 squeezes the clamping roller 21, and the pressure spring 19 is under pressure at this time (it should be noted that the pressure applied by the pressure spring 19 to the sub-line 10 at this time is the same as the pressure applied by the sub-line 10 to the clamping roller 21 when the sub-line 10 is taut). When a sub-line 10 becomes loose during the twisting process, the corresponding clamping roller 21 will press the sub-line 10 to move under the action of the pressure spring 19 (at this time, the force generated by the reset of the pressure spring 19 is greater than the force applied by the sub-line 10 to the clamping roller 21), and the sliding support plate 18 slides in the accommodating groove 15, squeezing the loose sub-line 10 with the clamping roller 21, and the sliding of the sliding support plate 18 in the accommodating groove 15 will drive the deceleration output end of the brake mechanism to operate through the transmission mechanism, and then correct the storage wheel 5 corresponding to the loose sub-line 10 through the deceleration output end.
[0049] In order to show the detailed structure of the brake mechanism, the following features are also set:
[0050] The brake mechanism also includes a load-bearing arc box 28 (such as a load-bearing arc box 28) arranged beside each storage wheel 5 and fixedly connected to the load-bearing support plate 3. Figure 6 As shown in the figure, a carrying square box 33 is fixedly arranged on the side of the carrying arc box 28 away from the storage wheel 5, a trigger slide 34 is slidably arranged in the carrying square box 33, a plurality of limiting square tubes 29 are fixedly arranged at equal intervals along the length direction of the carrying square box 33, a push rod 30 elastically slidably arranged in each limiting square tube 29 and a friction disk 6 coaxially fixedly arranged on the rotating shaft of the storage wheel 5, the friction disk 6 is rotatably installed in the carrying arc box 28, one end of the limiting square tube 29 is fixedly connected to the carrying square box 33, and the other end is fixedly connected to the carrying arc box 28, the push rod 30 passes through the side wall of the carrying arc box 28 and the side wall of the carrying square box 33, a friction head 31 is arranged on the side of the push rod 30 close to the friction disk 6, and the sliding support plate 18 is connected to the trigger slide 34 through a transmission mechanism.
[0051] In order to ensure that the triggering slide bar 34 can more smoothly push out the extension rod 30 when sliding in the supporting square box 33, the following features are also specifically provided:
[0052] One end of the trigger slide bar 34 extending into the supporting box 33 is provided with a resisting inclined surface 35 , and the resisting inclined surface 35 is used to contact the extending rod 30 .
[0053] The friction head 31 is the deceleration output end of the brake mechanism.
[0054] When the equipment is running, the sliding of the sliding support plate 18 in the accommodating slide groove 15 will first drive the transmission mechanism to operate, and the operation of the transmission mechanism causes the sliding bar 34 to slide in the bearing box 33, and the sliding of the sliding bar 34 will move with the plurality of top extension rods 30 in sequence to contact the friction disk 6, and then the friction head 31 will be used to slow down the rotation speed of the friction disk 6. When the friction disk 6 is decelerated by force, the rotating shaft of the storage wheel 5 will be decelerated accordingly, so that the wire-releasing speed of the storage wheel 5 will be slowed down, and as the stranding continues, until the slackened sub-line 10 is tightened again, the sub-line 1 0 The force generated by the pressing roller 21 is again the same as the force generated by the pressure spring 19. It should be noted that the distance that the sliding support plate 18 slides in the receiving slot 15 is proportional to the distance that the triggering slide bar 34 slides in the bearing square box 33. The longer the sliding support plate 18 slides in the receiving slot 15, the more serious the relaxation of the sub-line 10 is reflected, and the longer the triggering slide bar 34 slides in the bearing square box 33, and more pushing rods 30 can be pushed out. The more friction heads 31 come into contact with the friction disk 6, the more obvious the deceleration effect of the friction disk 6 is.
[0055] In order to show the detailed structure of the transmission mechanism, the following features are also set:
[0056] The transmission mechanism includes a liquid storage tube 23 (such as Figure 4 As shown in the figure, a first piston rod 24 coaxially slidably arranged in the liquid storage tube 23, a drag rod 22 fixedly connected to the first piston rod 24, a transfer tube 25 arranged on the liquid storage tube 23, a plurality of liquid inlet tubes 43 fixedly arranged in an annular shape on the support plate 2, and a second piston rod 44 elastically slidably arranged in the liquid inlet tube 43, the second piston rod 44 is transmission-connected to the trigger slide 34, one end of the transfer tube 25 is connected to the liquid storage tube 23, and the other end is connected to the liquid inlet tube 43 through the load-bearing ring 12, and hydraulic oil is stored in the liquid storage tube 23.
[0057] When the sliding support plate 18 slides in the receiving slide groove 15, the sliding support plate 18 drives the first piston rod 24 to move through the drag rod 22, thereby squeezing the hydraulic oil in the liquid storage tube 23 (it should be noted that under normal circumstances, the first piston rod 24 is retracted in the liquid storage tube 23, and the hydraulic oil in the liquid storage tube 23 is full) into the liquid transfer tube 25, and then the hydraulic oil enters the liquid inlet pipe 43 to push the second piston rod 44 to extend, and the second piston rod 44 extends to drive the touch slide 34 to move.
[0058] In order to ensure that the movement of the touch slider 34 is more stable when the device is running, the following features are also specifically provided:
[0059] The brake mechanism also includes a limiting wedge bar 26 fixedly arranged on the side of the bearing square box 33, a transmission rack 27 slidably arranged on the limiting wedge bar 26, two mounting frames 36 fixedly arranged on the bearing support plate 3 at equal intervals, a threaded tube 37 rotatably arranged on the two mounting frames 36, a threaded rod 38 coaxially arranged in the threaded tube 37, a worm gear 39 coaxially fixedly arranged on the threaded tube 37, a U-shaped bracket 40 fixedly arranged on the mounting frame 36 close to the worm gear 39, a worm 41 rotatably arranged on the U-shaped bracket 40 and a transmission gear 42 coaxially fixedly arranged on the worm 41, the threaded rod 38 is threadedly connected to the threaded tube 37, the trigger slide 34 is fixedly connected to the threaded rod 38, the transmission rack 27 is meshed with the transmission gear 42, the transmission rack 27 is transmission-connected to the second piston rod 44, and the worm gear 39 is meshed with the worm 41.
[0060] When the device is running, the second piston rod 44 extends out and drives the transmission rack 27 to slide on the limiting wedge strip 26. The sliding of the transmission rack 27 causes the transmission gear 42 to rotate. The rotation of the transmission gear 42 drives the worm 41 to rotate. The rotation of the worm 41 drives the worm wheel 39 to rotate. The rotation of the worm wheel 39 drives the threaded tube 37 to rotate. Then, under the action of the thread, the threaded rod 38 extends along the axis of the threaded tube 37, so that the threaded rod 38 drives the touch slide 34 to extend. Through the above structure, the touch slide 34 can run stably in the bearing square box 33. In addition, when After the correction is completed, the second piston rod 44 is reset, and the hydraulic oil is pressed into the transfer tube 25 again, and finally returns to the liquid storage tube 23. The reset of the second piston rod 44 drives the transmission rack 27 to reset, and the reset of the transmission rack 27 drives the transmission gear 42 to reverse, and the reversal of the transmission gear 42 drives the worm 41 to reverse, and the reversal of the worm 41 drives the worm wheel 39 to reverse, and the reversal of the worm wheel 39 drives the threaded tube 37 to reverse, and the reversal of the threaded tube 37 causes the threaded rod 38 to retract into the threaded tube 37 again, and the threaded rod 38 retracts into the threaded tube 37 and drives the touch slide 34 to reset.
[0061] In order to ensure that the second piston rod 44 can better push the transmission rack 27 to move, the following features are also specifically provided:
[0062] The transmission mechanism also includes a limiting slide 46 fixedly arranged on the bearing support plate 3, a fixed box 47 fixedly arranged on the limiting slide 46, a movable box 48 slidably arranged on the limiting slide 46, a rope rack 45 fixedly arranged at the end of the second piston rod 44 and a reset spring 50 arranged on the movable box 48, pulley groups are arranged in the movable box 48 and the fixed box 47, a pull rope 49 is arranged on the rope rack 45, the pull rope 49 passes around the pulley groups in the movable box 48 and the fixed box 47, and the end of the pull rope 49 is fixedly connected to the rope rack 45, one end of the reset spring 50 is connected to the movable box 48, and the other end is connected to the support plate 2, and the movable box 48 is fixedly connected to the transmission rack 27.
[0063] When the second piston rod 44 is extended, the second piston rod 44 extends to drive the rope rack 45 to move and pull the pull rope 49. After the pull rope 49 is pulled, it is transmitted through the pulley group (the structural principle here refers to the labor-saving pulley principle) to make the movable box 48 slide on the limiting slide bar 46. The sliding of the movable box 48 drives the transmission rack 27 to move; in addition, when the second piston rod 44 is reset, the movable box 48 is also reset under the action of the reset tension spring 50.
[0064] A conductor processing process with low cost and high conductivity includes the following steps:
[0065] S1: Drawing and shaping the sub-wire 10 through a wire drawing die;
[0066] S2: Winding the sub-wires 10 onto the busbar 9 through the stranding die 17, and winding a suitable number of layers as required;
[0067] S3: During the stranding process, the tension detection mechanism constantly detects the tension of the sub-wires 10. When a certain sub-wire 10 becomes loose, the detection output terminal runs through the transmission mechanism and then drives the brake mechanism to run, so that the deceleration output terminal in the brake mechanism adaptively decelerates the rotating shaft of the storage wheel 5. The greater the degree of looseness of the sub-wire 10, the stronger the deceleration effect applied by the deceleration output terminal to the rotating shaft of the storage wheel 5.
[0068] S4: The correction of the wire storage wheel 5 is completed, the slack sub-wire 10 is tightened again, the deceleration output end and the detection output end are reset, and the equipment continues to operate normally.
[0069] The working principle of this device is as follows: first, the sub-wire 10 is passed through a wire drawing die to be transformed into a wire with a shaped or circular cross section, and then the main wire 9 and several sub-wires 10 are stretched out and passed through a stranding die 17, and then pulled and reeled by a traction device, and then the support disk 2 rotates to drive all the wire storage wheels 5 to rotate, and then the stranding step begins, and the sub-wire 10 is spirally wound around the main wire 9 in coordination with the pulling of the traction device. When a certain sub-wire 10 becomes slack, the pressure spring 19 drives the sliding support plate 18 to slide in the receiving slide groove 15, and the sliding support plate 18 drives the first piston rod 24 to move through the drag rod 22, thereby squeezing the hydraulic oil in the liquid storage tube 23 (it should be noted that under normal circumstances, the first piston rod 24 is retracted in the liquid storage tube 23, and the hydraulic oil in the liquid storage tube 23 is full) into the transfer tube 25, and then the hydraulic oil enters the liquid inlet pipe 43 to push the second piston rod 44 to extend, and the second piston rod 44 extends to drive the rope rack 4 5 moves and pulls the pull rope 49. After the pull rope 49 is pulled, it is transmitted through the pulley group (the structural principle here refers to the principle of labor-saving pulley) to make the movable box 48 slide on the limit slide bar 46. The sliding of the movable box 48 drives the transmission rack 27 to move. The sliding of the transmission rack 27 causes the transmission gear 42 to rotate. The rotation of the transmission gear 42 drives the rotation of the worm 41. The rotation of the worm 41 drives the rotation of the worm wheel 39. The rotation of the worm wheel 39 drives the rotation of the threaded tube 37. Then, under the action of the thread, the threaded rod 38 moves along the threaded tube 3 The axis of 7 extends out, so that the threaded rod 38 drives the touch slide bar 34 to extend out, and the sliding of the touch slide bar 34 will move with the plurality of top extension rods 30 in sequence to contact the friction disk 6, and then the rotation speed of the friction disk 6 will be decelerated by the friction head 31. When the friction disk 6 is decelerated by force, the rotating shaft of the storage wheel 5 will be decelerated accordingly, so that the release speed of the storage wheel 5 will be slowed down until it returns to normal. After waiting for it to return to normal, the relaxed sub-line 10 is tightened again, and the force generated by the sub-line 10 on the pressing roller 21 is again combined with the pressure roller 21. The force generated by the force spring 19 is the same. It should be noted that the distance that the sliding support plate 18 slides in the receiving slide groove 15 is proportional to the distance that the triggering slide bar 34 slides in the bearing square box 33. The longer the sliding support plate 18 slides in the receiving slide groove 15, the more serious the relaxation of the sub-line 10 is reflected, and the longer the distance that the triggering slide bar 34 slides in the bearing square box 33 is, and the more extension rods 30 can be pushed out. The more friction heads 31 contact the friction disk 6, the more obvious the deceleration effect of the friction disk 6 is. Wait for the correction to end, the equipment is reset, the movable box 48 is reset under the action of the reset tension spring 50, the reset of the movable box 48 drives the transmission rack 27 to reset, and the reset of the second piston rod 44 allows the hydraulic oil to return to the reservoir 23, which is convenient for the next work.
