Technical field
The utility model relates to a kind of electric wire that possesses higher bending fatigue resistance energy, concrete must saying, relate to and a kind ofly form surface sclerosis by electric wire wire wicking surface being applied to residual compressive stress and certain plastic deformation, and by fiber composite silk thread, core is wound around to pressurization to maintain the residual compressive stress on core surface and the surface sclerosis electric wire with the resistance to bending fatigue strength of raising electric wire.
Background technology
Various electric wires are after the bending of certain number of times, and fatigue damage unavoidably can occur for its conductor wire core and insulating barrier.In as many machineries such as gantry crane, mine equipment, flexible display and electronic product, it is one of the Main Bottleneck in decision device useful life that the flexural fatigue of electric wire is damaged.Take crane cable as example, mainly play the effect of electric energy transmitting and signal monitoring, be the crucial matching component that determines handling machinery and service life of equipment.In this cable use procedure, because frequently being moved back and forth, continuous bend, reverse and have the mechanical stress effects such as stretching that inertia pulls, especially because spatial limitation, in the middle of the cable of crane, reverse wheel bending diameter hour, because the stack of bending and tensile stress is with concentrated, be difficult to be guaranteed the useful life of cable.
For existing electric wire, flexibility, the bending fatigue resistance of conventional Plastic-sheathed Cable are not good enough, lack enough tensions, compression strength, inadaptable frequently moving back and forth and continuous bend.Between cable insulation core and between each contact, lack enough bending degrees of freedom.In the time that cable core is bending, be positioned at elastic line (being neutral line) upper guide wire core stretcher strain can occur, there is compression in lower guide wire core.Now, the upper guide wire core being stretched may be torn because of fatigue of materials, and lower guide wire core may produce outstanding and gauffer because of fatigue of materials.Cyclic bending finally can cause the fracture of wire core like this, and exposes and damage insulating barrier.
For being subject to bending material, it is applied to suitable surface pressing and can form a cementation zone by surface plastic deformation, can hinder the appearance of superficial layer fatigue crack, thereby part fatigue strength is obviously improved.
For being subject to bending material, if when residual compressive stress is left on its surface, expansion that also can delay fatigue crackle, improves the fatigue strength of part; But in the time that residual tension is left on its surface, but easily make piece surface crack and reduce its fatigue strength.
With respect to conductive copper wire and aluminum steel, the tensile strength of fibre reinforced composites silk thread is higher, as the about 400MPa of nylon-66 line tensile strength of 50% glass fibre reinforcement, bending strength is about 590MPa, higher than the mechanical performance (being about 389MPa according to its tensile strength of GB) of the above conventional copper cash of 3mm diameter.And take PEEK as matrix, the composite material that 61% S-glass fibre strengthens, its tensile strength can reach 1158MPa, and bending strength can reach 1246MPa, far away higher than copper cash, and splendid from the fatigue strength under alternate stress.
The processing of electric wire core is that copper or aluminum steel base are passed through to one or many bracing wire technique in bracing wire mould by guy-line equipment, produces the wire rod of big-length and various required wire diameters.In process of production, reel is coarse, improper etc. the various factors of line mould dimension overproof, the coarse distortion of line mould nib, insufficient lubrication or lubricating fluid excess Temperature, equipment shake, takeup tension all may make wire surface damage, and causes core fatigue strength greatly to reduce.
Utility model content
For solving the core of existing electric wire and the problem that insulating barrier bending fatigue resistance can be not good, the utility model provides a kind of electric wire of resistance to flexural fatigue.
For achieving the above object, the technical solution of the utility model is:
An electric wire for resistance to flexural fatigue, is characterized in that, comprising: conductor wire core, described conductor wire core surface voluble wrapping has fibre reinforced composites silk thread, between the turn of described fibre reinforced composites silk thread, is provided with adhesive.
In the utility model, described fibre reinforced composites silk thread is carbon fibre composite silk thread or glass fibre reinforced composite silk thread.
In the utility model, described fibre reinforced composites silk thread compresses to be wound around and is wrapped in conductor wire core surface.
In the utility model, described adhesive interval between the turn of described fibre reinforced composites silk thread arranges.
Described adhesive spaced spacing between the turn of described fibre reinforced composites silk thread is 5cm to 10cm.
In the utility model, described adhesive extends to wire wicking surface, and described adhesive is epoxy glue.
In the utility model, described fibre reinforced composites silk thread outward again cover to have insulation protection tube, described insulation protection tube be rubber protection tube.
The utility model compared with prior art, strengthen from conductor wire core being applied to surface compress residual stresses and plastic surface the fatigue strength that obviously improves conductor wire core, and by the coated fibre reinforced composites silk thread with larger tension stress of conductor wire core spiral winding, make the surface coated silk thread of core produce residual compressive stress and the surface peening of lasting compression with long term maintenance core surface to conductor wire core.The utility model can increase substantially the bending fatigue resistance energy of wire core, also has higher insulating barrier bending fatigue resistance energy simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of utility model.In figure, 1 conductor wire core; 2 fibre reinforced composites silk threads; 3 adhesives.
Embodiment
Be elaborated below in conjunction with accompanying drawing.The electric wire of the resistance to flexural fatigue of the utility model comprises, conductor wire core 1, and the surperficial voluble wrapping of conductor wire core 1 has fibre reinforced composites silk thread 2, is provided with adhesive 3 between the turn of fibre reinforced composites silk thread 2.Described conductor wire core 1 is for electric energy transmitting or the signal of telecommunication, and it can eliminate main blemish by multiple tracks rolling technology after bracing wire production technology, has obtained rational surface residual stress and surface peening to improve the bending fatigue resistance energy of self.Described fibre reinforced composites silk thread 2 spiral windings are coated on conductor wire core 1 surface, and in the time that twisting, coiling maintains higher tension stress, the tension stress of fibre reinforced composites silk thread 2 self can be converted into the compression of long term on conductor wire core 1 surface, makes fibre reinforced composites silk thread 2 compress to be wound around and is wrapped in conductor wire core 1 surface.This additional compression can guarantee that conductor wire core 1 drawing stress on surface that stretcher strain produces in BENDING PROCESS is unlikely to offset intrinsic residual compressive stress to reduce the possibility of surface generation fatigue crack, also can make conductor wire core 1 surface in the time being compressed of neutral line below be difficult for producing projection and gauffer defect, further improve the resistance to flexible life of conductor wire core 1.Because the tensile strength of fibre reinforced composites silk thread 2 is obviously better than conductor wire core 1; as long as so guarantee that helically coiling is far smaller than the tensile strength of its material itself because twisting the tension stress producing at the fibre reinforced composites silk thread 2 on conductor wire core 1 surface; and no matter how curved fiber reinforced composite silk thread 2 is always under simple tension state wire; can be higher than conductor wire core 1 as the fatigue strength of the fibre reinforced composites silk thread 2 of inner insulating layer, play reliable insulation and protection effect.Described fibre reinforced composites silk thread 2 is preferably as carbon fibre composite silk thread or glass fibre reinforced composite silk thread.
If but fibre reinforced composites silk thread 2 shears or the fracture of the reason such as puncture because of external force, originally the fibre reinforced composites silk thread 2 of helically coiling outside conductor wire core 1 whole moment collapses loose possibly.Described adhesive 3 interval between the turn of described fibre reinforced composites silk thread 2 arranges, described adhesive 3 spaced spacing between the turn of described fibre reinforced composites silk thread 2 is 5cm to 10cm, in conductor length direction, (as 5～10cm left and right) glued together and fixed between one or several turns and with conductor wire core surface 1 use adhesive 3 fibre reinforced composites silk thread 2 often across a certain distance, with the fibre reinforced composites silk thread fracture 2 of guaranteeing accidentally to occur, or wire is cut off to docking operation can not affect the insulated wire self-tightening effect of whole wire, eliminated fibre reinforced composites silk thread 2 because of the potential impact of the issuable local creep of the reasons such as manufacturing defect to wire entirety anti-fatigue performance simultaneously.Described adhesive 2 is preferably and extends to wire core 1 surface, and described adhesive 3 is preferably employing epoxy glue.
Preferably; for preventing that fibre reinforced composites silk thread 2 from causing unexpected fracture and because crossing the reason generation premature agings such as intensive ultraviolet, the protection tube that can overlap again one deck rubber or similar material outside fibre reinforced composites silk thread 2 is as external insulation layer because of external force damage.
