Embodiment Construction

[0012] An energy-saving and consumption-reducing cable conductor manufacturing method, the manufacturing device includes a large copper wire drawing machine, a special-shaped wire drawing die, an I-wheel take-up and a stranding machine, and the cable conductor manufacturing steps are:

[0013] 1) Draw the round copper rod with TRФ8mm and resistivity less than 0.0171Ω / mm² / m into copper wire. The copper wire adopts a 13-mode / 450 continuous annealing copper wire drawing machine. The wire-passing die is a polycrystalline diamond circular die and the terminal die It is Ф380 and 400mm long, and the inner drawing wire adopts a tile shape. The diameter of the single wire is Ф2.8mm, the finished surface is 6.16mm², and it is continuously annealed to become soft copper wire, and the wire is taken up by a Ф630mm I-shaped wheel;

[0014] 2) The stranding machine has a frame structure of 84 discs / Ф630. The stranding machine includes a pay-off rack, four-segment twisting cages arranged in se...

Abstract

The invention provides an energy-saving and consumption-reducing cable conductor manufacturing method. The cable conductor manufacturing method includes the following steps: round copper rods are drawn into copper wires, the copper wires are continuously annealed into soft copper wires by using a continuous annealing copper wire drawing machine, and the soften copper wires are wound by an I-shapedwheel; a stranding machine can adjust pitch, rotation direction, PLC man-machine interface control, and polycrystalline drawing die on each segment; the copper wires on the I-shaped wheel wound wiresare on the frame type stranding machine, the pitch diameter ratio of each outer layer is not greater than the pitch diameter ratio of the inner layer, and the cable conductors are twisted into a strand; and the cable conductors twisted into a strand are stored in a cable tool disk by a tractor and a winding machine. The advantages of the energy-saving and consumption-reducing cable conductor manufacturing method are that the cable conductor is of a special-shaped single-filament stranded structure and has the advantages of reduced gaps between filaments, smooth, bright and round appearance, reduced diameter, improved density, more stable resistance and improved cable quality, and the method reduces the consumption of materials and increases the economic benefit of an enterprise.
