Description

Technical Field

[0001] The utility model relates to the technical field of cable stranding equipment, in particular to a cable stranding equipment for cable production. Background Art

[0002] The wire stranding machine is a kind of mechanical equipment that can be widely used in the stranding of various soft / hard conductor wires, so that multiple single conductors can be twisted into one strand to meet the process requirements of the wire.

[0003] Traditional power cables mostly use copper conductors as cable core materials, but in order to reduce energy consumption and save costs, it has become a trend to replace copper conductors with aluminum alloy conductors as cable core materials. However, the material hardness and heat resistance of aluminum alloy conductors are not as good as copper conductor materials. Therefore, when twisting wires, the traditional twisting machine will easily produce aluminum chips due to the mutual extrusion and friction between aluminum alloy conductors as the mold temperature rises during the twisting process. Aluminum chips and powder accumulate in the mold cavity, which can easily cause the surface of the cable core to become rough. Even because the aluminum chips are hardened by heat, they adhere to the surface of the cable core and easily cause the aluminum single wire to break. In severe cases, the entire cable core will break, reducing the processing yield and product life. In view of the above situation, technical innovation is carried out on the basis of the existing cable twisting equipment for cable production. Utility Model Content
