Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy conductor material processing, and in particular to an aluminum alloy cable heat treatment and twisting continuous production line and a production process thereof. Background Art

[0002] In recent years, aluminum alloy wires with strong torsion resistance and bending performance have been developed for new energy wind power, photovoltaics, etc. The production of aluminum alloy wires is more complicated than copper wires. The wire drawing lubricants used in the production process of aluminum alloy wires are mainly oil-based. Aluminum alloy wires with a diameter of less than 0.5 mm may use emulsions in the drawing process, and the emulsion must increase the oil content to meet the drawing process requirements of aluminum alloy wires. In order to remove the residual oily lubricant on the surface of the aluminum alloy wire, a cleaning process must be added before the annealing heat treatment process can be entered. It is not convenient to clean during high-speed wire drawing, and cleaning requires a single process. The subsequent annealing heat treatment is annealed in a coiled wire box furnace, and then bundled into strands after annealing. The wire bundling machine is currently the fastest equipment for stranding aluminum alloy wires with thinner diameters into stranded wires, but compared with the manufacturing process of aluminum alloy wires with thicker diameters, the efficiency of the wire bundling machine is still relatively low. The cleaning, annealing and bundle twisting processes of aluminum alloy wires with smaller diameters are independent, which leads to low efficiency. This is acceptable in small-batch production, but when the product usage increases, high efficiency, energy saving and green environmental protection become the main goals.

[0003] How to design a production line that can connect three processes of cleaning, heat treatment and stranding at similar speeds to improve production efficiency is a problem that technicians in this field need to solve. Summary of the invention

[0060] The production process of the aluminum alloy cable heat treatment and stranding continuous production line of this embodiment includes the following steps:

[0061] 1) When all the aluminum alloy single wires 10 are installed on the aluminum alloy cable heat treatment stranding continuous production line, multiple aluminum alloy single wires 10 are released from the pay-off frame 100, and all the aluminum alloy single wires 10 enter the cleaning machine 300 through the pay-off wire guide wheel frame 200; after all the aluminum alloy single wires 10 pass through the cleaning wire break protection device 920, they enter the cleaning part outlet wire storage device 610; after that, all the aluminum alloy single wires 10 pass through the continuous annealing furnace 400, and then pass through the annealing furnace wheel traction machine 430, and then pass through the furnace break protection device 910, and enter the annealing part outlet wire storage device 620; then, all the aluminum alloy single wires 10 first pass through the spare wire pay-off machine 800, and all the aluminum alloy single wires 10 respectively pass through the corresponding branch wire guide wheel frames 700, and then enter the wire bundling machine 500;

[0062] 2) When the aluminum alloy cable heat treatment and twisting continuous production line is started, all the aluminum alloy single wires 10 are transported in the aluminum alloy cable heat treatment and twisting continuous production line, the flushing module 320 rinses all the aluminum alloy single wires 10 entering the cleaning machine 300, and the drying module 330 dries all the aluminum alloy single wires 10 entering the cleaning machine 300; the blowing nozzle 440 at the entrance of the continuous annealing furnace 400 blows cold air to all the aluminum alloy single wires 10 passing through, and the continuous annealing furnace 400 anneals the aluminum alloy single wires 10; after the annealing furnace wheel traction machine 430 pulls all the aluminum alloy single wires 10 out of the continuous annealing furnace 400, all the aluminum alloy single wires 10 enter the corresponding branching guide wheel frame 700, and then enter the wire bundling machine 500 to form a stranded wire bundle;

[0063] When the wire take-up reel 510 on the wire bundling machine 500 needs to be replaced, the wire bundling machine 500 is stopped, and the aluminum alloy single wire 10 is stored through the annealing section outlet wire storage device 620 at the front end of the wire bundling machine 500;

[0064] When the aluminum alloy single wire 10 in the cleaning machine 300 breaks and forms a broken wire, the cleaning broken wire protection device 920 is started, the wire bundling machine 500 stops, and the wire bundling machine 500 outputs an alarm signal; the spare wire on the spare wire take-up and pay-off machine 800 is connected to the broken joint of the broken wire entering the wire bundling machine 500, and then the wire bundling machine 500 is started to continue running;

[0065] When the aluminum alloy single wire 10 in the continuous annealing furnace 400 breaks and forms a broken wire, the furnace-out broken wire protection device 910 is started, the wire bundling machine 500 stops, and the wire bundling machine 500 outputs an alarm signal; the spare wire on the spare wire take-up and pay-off machine 800 is connected to the broken joint of the broken wire entering the wire bundling machine 500, and then the wire bundling machine 500 is started to continue running.

[0066] In this embodiment, the outer diameter of the pay-off drum 110 is 280-400 mm, the wire loading length of the pay-off drum 110 is 20000-60000 m, and the aluminum alloy single wire 10 is paid out from the pay-off frame 100 .

[0067] When the aluminum alloy single wire 10 enters the cleaning machine 300, the aluminum alloy single wire 10 passes through the flushing module 320 and the blow-drying module 330 in the cleaning machine 300, and then the aluminum alloy single wire 10 passes through the traction component 340, and then the aluminum alloy single wire 10 passes through the cleaning wire break protection device 920 and enters the annealing section outlet wire storage device 620; at this time, the cleaning machine 300 starts the low-speed cleaning mode, and the flushing module 320 of the cleaning machine 300 includes a cleaning module and a rinsing module, one of the blow-drying modules 330 is arranged between the cleaning module and the rinsing module, and the other blow-drying module 330 is arranged behind the rinsing module.

[0068] The aluminum alloy single wire 10 in the cleaning machine 300 is cleaned by the three-stage cleaning module, blown dry by the same pressure gas of one of the blowing modules 330, and then enters the second-stage rinsing module to rinse the aluminum alloy single wire 10, and blown dry by the high-pressure gas of another blowing module 330, and then the aluminum alloy single wire 10 is pulled out of the cleaning machine 300 by the traction component 340 and enters the continuous annealing furnace 400.

Environmentally friendly cleaning agents are used in the cleaning module.

[0069] The continuous annealing speed in the continuous annealing furnace 400 is used as the control base point of the aluminum alloy cable heat treatment and stranding continuous production line. The speeds of the cleaning machine 300 and the wire bundling machine 500 are increased and decreased according to the speed of the continuous annealing furnace 400. The continuous annealing speed in the continuous annealing furnace 400 is determined according to the heating temperature in the continuous annealing furnace 400.

[0070] The pay-off drum 110 is replaced once a day. During the peak electricity consumption period, the aluminum alloy cable heat treatment into stranded continuous production line is shut down and the pay-off drum 110 is replaced or operated at a low speed. During the off-peak period, the temperature is increased and the aluminum alloy cable heat treatment into stranded continuous production line is operated at a high speed.

[0071] The stranded wire produced by the aluminum alloy cable heat treatment and twisting continuous production line of the present invention mainly replaces the corresponding copper conductor. The performance of the stranded wire has reached or exceeded the level of the copper conductor, but the manufacturing cost of the stranded wire is reduced by about 50% compared with the copper conductor, which saves copper resources and has economic and social benefits.

[0072] Compared with the prior art, the present invention can connect the three processes of cleaning, annealing and twisting into bundles to form a continuous, automatic and intelligent production line, which greatly improves the production efficiency of fine wire strands, and the production efficiency is increased by at least 48%. At the same time, it also reduces production processes and intermediate flows, reduces energy consumption, and reduces the number of operators, ultimately reducing the production cost of fine wire strands and improving product quality.
