Nearly all port and pier all use lifting machine to carry out hauling operation, the higher extractive equipment of efficient has been used in exploitation under the mine, the blast furnace of metallurgy industry is because the restriction of environmental condition, the metal that dissolves can only be by the transportation of rail tank car ... the plant equipment of these occasions must be used a kind of special cable, its one is connected and fixed on the end, the other end is connected to the control cabinet of these plant equipment, on cable drum or the generating equipment, it is along with plant equipment carries out frequently moving, alternating bending, volume is scratched, stretch and reverse, we call flexible cable to this type of cable.
At present, flexible cable is most of for import, is homemade on a small quantity.Test data shows, the average fracture number of bends of flexible cable is no more than 20,000 times, hot strength has only 220～240Mpa, therefore be no more than 3 months average life, because the particularity of these use occasions, in case cable bad makes to produce and interrupts, cause enormous economic loss, return and keep in repair and change and bring very big trouble.
Flexible cable useful life short main cause be cable in use conductor wire core rupture, this factor has accounted for more than 95%, and by the simulation behaviour in service experiment to conductor wire core, finding to take place fracture has two kinds of situations, the one, break, the 2nd, bending fractures.Analyzing the reason of fracture finds: the thin copper single line that the conductor wire core of flexible cable is many same diameter closes (being called bunch) by same direction bundle, or forms by the multiply bunch is stranded (being called the bundle twisted wire).Because of the tensile strength of copper material is 220～240Mpa, therefore, small bore conduction cable core moves with equipment and is easy to break when bearing big tension.Because of bunch is informal stranded, the position between each single line is unfixing mutually again, and each single line produces following two kinds of situations when cable is crooked: the one, and each single line slip surplus is inequality, and the 2nd, each single line one side is stretched, and the another side is by compression; When other direction is crooked, what stretched originally has become compression; By compression become stretching; In alternating bending, the single line that the slip surplus is little at first begins to fracture, along with the increase of number of bends, increasing single line constantly fractures, up to complete rupture, or after the arrival some that fractures, when the tensile strength of residue conductor during less than tensile force, conductor wire core will be broken.
Summary of the invention
Technical problem to be solved by this invention provides a kind of rational in infrastructure, the manufacture method of conductor thread core in the better super flexible cable of tensile property, adopt the conductor thread core tensile strength of this method manufacturing to reach more than 1000 Mpa, the number of bends that on average ruptures is more than 100,000 times.
The manufacture method of conductor thread core in the super flexible cable of the present invention, it may further comprise the steps: require to select for use electrotechnical steel silk, electrotechnical steel silk rope, aramid fiber silk or the aramid fiber rope strengthening core as cable according to serviceability, strengthening core is passed through the rewinding machine after-combustion to steel dish tool, copper strand wire is woven into the manufacturing of finishing conductor thread core on the strengthening core in the strengthening core periphery by braiding machine then.
It is 0.20～1.0mm that above-mentioned electrotechnical steel silk is selected diameter for use, and it is 1.0～5.0mm that electrotechnical steel silk rope is selected diameter for use, and tensile strength is all between 850～1550Mpa.The aramid fiber silk is selected for use directly through being 0.20～1.0mm, and it is 1.0～5.0mm that the aramid fiber rope is selected diameter for use.
Above-mentioned copper strand wire is harness-integrated on doubling winder by the copper single line of the identical straight warp of 3-12 root, and parallel more neatly being wound on the drum that braiding machine uses used during for braiding.The structure of copper strand wire braiding is that per share copper strand wire covers other two strands of copper strand wires, and itself is covered by following two strands of copper strand wires.
The present invention uses by improvement and rational material to the conductor thread core manufacture method, make cable possess super flexibility, excellent bending, volume are scratched, are reversed, tensile property, thereby satisfy the needs of some special occasions, adopt the conductor thread core of this method preparation, tensile strength reaches more than 1000 Mpa, on average ruptures number of bends more than 100,000 times, reaches average life more than 1 year.
