Abstract
The invention relates to a novel stainless steel wire for spaceflight. The structure of the novel stainless steel wire is CFRC8*19W+8*17+1*15S or CFRC8*17S+8*7+1*15S. The stainless steel wire is formed by twisting a central strand, eight inner-layer strands and eight outer-layer strands in one step, wherein the structure of the central strand is 1+7+7 and is formed by twisting fifteen steel wires in one step, the structure of inner-layer strands is 1+6 and is formed by twisting seven steel wires in one step, and the structure of the outer-layer strands is 1+6+6/6 or 1+8+8 and is formed by twisting nineteen or seventeen steel wires in one step. The novel stainless steel wire for spaceflight can greatly enhance the bearing capability by being tempered in a continuous tempering furnace with protection gas and has the advantages of high bending and fatigue resistant property, good flexible property and abrasion resisting property, long service life, good safety property, and the like.
Description
Technical field
The present invention relates to a kind of stainless steel wire for spaceflight, belong to the metallic article technical field.
Background technology
Existing stainless steel wire for spaceflight is mainly structures such as 6 * 7+IWS, 6 * 19+IWS, and the thigh of steel wire rope is formed by the steel wire layering system of twisting with the fingers of same diameter; Be the point-like contact between its adjacent layer steel wire, and do not carry out temper after the twisting wire rope completion, steel wire rope is when winding reel or pulley bending; Steel wire receives addition bend in strand, produces second order buckling stress, and steel wire rope is prone to produce tired fracture of wire; And the steel wire rope bearing capacity is less; Abrasion resistance properties is poor, and steel wire rope is low service life, has potential safety hazard.Also do not see in the market CFRC8 * 19W+8 * 7+1 * 15S or CFRC8 * 17S+8 * 7+1 * 15S, stainless steel wire for spaceflight are arranged.Do not see and constructedly on public's medium, report.
Summary of the invention
The objective of the invention is in order to overcome deficiency of the prior art; Provide that a kind of intensity is high, metal filled coefficient and the rupture pull force coefficient is big, bearing capacity is big; Counter-bending fatigue behaviour is high, and softness and abrasion resistance properties are good, improve service life simultaneously; Reduce production costs the stainless steel wire for spaceflight of enhancing productivity.
The technical scheme that the present invention adopted is:
A kind of stainless steel wire for spaceflight, structural design are CFRC8 * 19W+8 * 7+1 * 15S or CFRC8 * 17S+8 * 7+1 * 15S, and steel wire rope is formed by a metal thigh core, eight internal layer thighs and eight outer layer strand primary twistings.Steel wire rope is for completely filling formula line contact structures.
Metal thigh cored structure is 1+7+7, is formed by 15 steel wire primary twistings, and internal layer thigh structure is 1+6, is formed by seven steel wire primary twistings, and outer layer strand is 1+6+6/6 or 1+8+8, is formed by 19 or 17 steel wire primary twistings respectively.Steel wire diameter can be twisted with the fingers the steel wire rope of system different-diameter in the change steel cord structure, and the steel wire rope lay pitch is 6.5～7.5 times of its nominal diameter.
After twisting wire rope was accomplished, through carrying out tempering in the tempering furnace continuously, temperature was 600～700 ℃; Tempering time is 150～260 seconds.Can improve the rupture pull force of stainless steel wire rope.
Adopt the beneficial effect of such scheme to be:
1, satisfies the demand of national spacecraft to steel wire rope;
2, steel cord structure is tight, and metal filled coefficient and rupture pull force coefficient are big, and the steel wire rope bearing capacity is big;
3, the bent fatigue behaviour of rope anti-bend is high, and softness and abrasion resistance properties are good;
4, steel wire rope high life, security performance is good;
Description of drawings
Accompanying drawing 1 is CFRC8 * 19W+8 of the present invention * 7+1 * 15S or CFRC8 * 17S+8 * 7+1 * 15S stainless steel wire for spaceflight schematic cross-section.
Among Fig. 1: 1-central strand, 2-internal layer thigh, 3 one outer layer strand.
The specific embodiment
A kind of stainless steel wire for spaceflight of the present invention, specific embodiment contrast accompanying drawing 1 is further described, and it is formed by a central strand 1, eight internal layer thighs 2 and eight outer layer strand 3 primary twistings.Wherein, central strand 1 structure is 1+7+7, is promptly formed by 15 steel wire primary twistings, and internal layer thigh structure is 1+6, is formed by seven steel wire primary twistings, and outer layer strand is 1+6+6/6 or 1+8+8, is formed by 19 or 17 steel wire primary twistings respectively.For completely filling formula line contact structures.
Change steel wire diameter wherein and can twist with the fingers the steel wire rope of system different-diameter, the steel wire rope lay pitch is 6.5～7.5 times of steel wire rope nominal diameter.
Accompanying drawing 1, stainless steel wire for spaceflight are by a central strand 1, eight isostructures, with diameter internal layer thigh 2 and eight isostructures, constitute with diameter outer layer strand 3.
After twisting wire rope was accomplished, through in having the continuous tempering furnace of protective effect, carrying out tempering, temperature was any number in 600～700 ℃ of intervals; Tempering time is 150～260 seconds interval any numerical value.Can improve the rupture pull force of stainless steel wire rope.
The stainless steel wire rope of embodiment: CFRC8 * 19W+8 * 7+1 * 15S structure, diameter 5.5mm, tensile strength 2160MPa, through carrying out tempering in the continuous tempering furnace of hydrogen as protective gas, temperature is 600～700 ℃; Tempering time is 150-260 second; Stainless steel wire rope does that duplex type is whole to be drawn test (steel cable is walked around φ 29mm pulley; Wheel rope is than being 5.27: 1), whole rope rupture pull force is greater than 45KN, and single rupture pull force of restricting is greater than 26kN; Steel wire rope through temper after the product bearing capacity improve greatly, its bearing capacity improves 30-35% than the common space flight of same specification with steel wire rope.
