Description
One, technical field
The present invention relates to a kind of production method of steel wire rope, relate in particular to a kind of production method of steel wire rope applied to high-speed railway touching net, belong to the metallic article technical field.
Two, background technology
Along with the progress of science and technology, we have entered into the epoch of high-speed railway.China at present in the train speed per hour of the high speed railways such as Beijing-Shanghai express railway Line for Passenger Transportation of founding a capital more than 350Km/h.Original electrification railway contact net is pure stainless steel wire rope with the steel wire rope employing, and its feature is that antiseptic property is good, but rupture pull force is not high.High-speed railway is very high with requirements of Wire Rope to contact net, not only wants high rupture pull force, and high antiseptic property will be arranged, and original for this reason electrification railway contact net can not satisfy the requirement of high ferro with steel wire rope.
Three, summary of the invention
At above-mentioned shortcoming, the object of the present invention is to provide the production method of the steel wire rope applied to high-speed railway touching net of a kind of high rupture pull force, high antiseptic property.
Technology contents of the present invention is, a kind of production method of steel wire rope applied to high-speed railway touching net, and its step is as follows:
(1), be that 0.2～1.0mm, intensity level are that to make structure by strander be that 1 * 19W, diameter are the parallel sth. made by twisting strand of 1.5～3.5mm for the surface heat zinc-coated wire of 1800～2300MPa with diameter, the lay pitch is 12～28mm in twisting with the fingers burst process, the oiling mode is a burst mode of drenching oil, and its grease is a wire-rope oil fat;
(2), be that 0.2～1.0mm, intensity level are that the surface heat zinc-coated wire of 1800～2300MPa makes by strander that structure is 1 * 7, diameter is the rope strand of 1.0～2.0mm with diameter; The lay pitch is 7～14mm in twisting with the fingers burst process, and the oiling mode is a burst mode of drenching oil, and its grease is a wire-rope oil fat;
(3), be that 0.1～1.0mm, intensity level are that to make structure by strander be that 1 * 29Fi, diameter are the parallel sth. made by twisting strand of 2.0～3.5mm for the surface heat zinc-coated wire of 1800～2300MPa with diameter; The lay pitch is 16～28mm in twisting with the fingers burst process, and the oiling mode is a burst mode of drenching oil, and its grease is a wire-rope oil fat;
(4), the parallel parallel sth. made by twisting thigh that makes in the rope strand that makes with step (2), the step (3) of twisting with the fingers strand that makes in the step (1) is made the closely knit steel wire rope applied to high-speed railway touching net of parallel sth. made by twisting that structure is 8 * 29Fi+8*7+1 * 19W by rope-forming machine, the steel wire rope rope directly is 8～13mm, the lay pitch is 40～120mm, its oiling mode in closing the rope process is a burst mode of drenching oil, and its grease is a wire-rope oil fat.
Because steel wire rope applied to high-speed railway touching net requires high rupture pull force, and the not change of whole steel wire rope using system, so the present invention selects the agent structure of the closely knit steel wire rope of parallel sth. made by twisting as steel wire rope for use; The closely knit steel wire rope of parallel sth. made by twisting is than the activity coefficient height of other common linear contact lay wire ropes, and activity coefficient reaches about 62%, and equal conditions can obtain high rupture pull force by the raising of fill factor of rope down; And the closely knit steel cord structure of parallel sth. made by twisting is stable, the fatigue life that helps improving steel wire rope.
Steel wire rope applied to high-speed railway touching net is exposed in the air throughout the year and uses, require steel wire rope that good antiseptic property is arranged, therefore the surface of all steel wires is zinc-plated state formation galvanized steel wire rope in the steel wire rope, because the design service life of steel wire rope applied to high-speed railway touching net is longer, simple plating zinc on surface state can't satisfy the required whole requirement for anticorrosion of steel wire rope applied to high-speed railway touching net, we adopt and use the grease seal steel wire rope, make steel wire in the steel wire rope not increase the corrosion resistance of steel wire rope with the method that air directly contacts.Therefore, in twisting with the fingers burst operation, adopt burst oily technology of pouring, make all steel wires in all steel strands all drench grease fully, and all be filled with grease in the slit between steel wire.The same burst oiling mode of drenching oil that adopts makes and all is filled with grease in the steel wire rope in the slit between all steel strands in closing the rope operation.
Because the weather spring, summer, autumn and winter of China makes a clear distinction between the four seasons, so the grease that steel wire rope applied to high-speed railway touching net adopted must possess the performance of anti-high and low-temp.Its requires to possess under 55 ℃ of the high temperature does not trickle, the characteristic of not embrittlement under the low temperature-25 ℃.By analyzing contrast, the wire-rope oil fat that we select for use can keep primary characteristic in-45 ℃～70 ℃ temperature range.
The present invention compared with prior art has following characteristics:
1, adopts the closely knit steel cord structure of parallel sth. made by twisting, activity coefficient height, rupture pull force height.
2, galvanizing+grease sealed protection combination is better than pure zinc-plated antiseptic property greatly, safeguards by regular interpolation grease, can be near pure stainless antiseptic property.
Four, description of drawings
