Abstract
The invention relates to a pouring experiment method for overall breaking force of a steel wire rope. In the method, an epoxy resin pouring method is adopted for a tensile test; and raw materials adopted by the method comprise the following components according to parts by weight: 8-15 parts of epoxy resin, 0.2-0.6 part of ethidene diamine, 3-8 parts of DBP, 4-8 parts of quartz sand and 1-5 parts of talcum powder. Compared with the prior art, the method has the beneficial effect that a contrast experiment is carried out by steel wire ropes with five types of structures such as 6V*34+NF, 6V*37S+NF and the like as well as more than 30 specifications by two methods; resin pouring can improve the breaking force of the whole steel wire rope by 10% compared with alloy pouring; the test data of the method is closer to the real breaking force of the steel wire rope, which is more favourable for design of the steel wire rope and determination of technological parameters; and raw material cost is lower.
Description
Technical field
The present invention relates to a kind of pouring experiment method for overall breaking force of steel wire rope.
Background technology
In the prior art, the whole rope of wire rope actual measurement rupture pull force test method mainly contains four kinds:
1, casting: the sample head that looses use poured with molten metal, be cooled to normal temperature after, be clamped in the method for carrying out tension test in the experimental machine jaw seat, general wirerope diameter adopts more than 20mm, the whole rope of wire rope is tested this method that generally adopts at present.
2, cover platen press: the sample head is compressed with sleeve pipe, in being clamped in the testing machine jaw, carry out the method for tension test.As the clinching of wirerope diameter more than 15mm adopt this method, be mainly the firm degree that combines with wire rope of check pipe box, special-purpose clinching equipment must be arranged, cost is than higher, generally rope test does not adopt this method.
3, winding method: sample directly is wrapped in the method for carrying out tension test on the rolling wheel.This method generally is to be used for the following wire rope of diameter 20mm.
4, direct chucking method: sample holder is carried out stretching test method in the testing machine jaw.This method generally is used for the following and wire rope simple in structure of diameter 6mm.
In sum, adopt alloy pouring procedure (being generally alloys such as zinc, lead), wire rope heating-up temperature in casting process is too high, easily produce annealing apart near the steel wire the cast position in the wire rope, the test wire rope is generally causing the breaking force of rope value to reduce than being easier to apart near the position disconnection the cast position, influence rope test result's accuracy, even test is cancelled.For reducing this loss, improve the overall breaking force of steel wire rope accuracy of experimental results, select for use this method to test.
Adopt non-alloy casting because the material cost of selecting for use than higher, is used when being not suitable for testing.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, a kind of pouring experiment method for overall breaking force of steel wire rope is provided, this method adopts epoxy resin to pour into a mould, by comparing test with the alloy casting, the test figure that records is more near the true rupture pull force of wire rope, and is more favourable to the design of wire rope and determining of technological parameter, and raw materials cost is lower.
The present invention is achieved through the following technical solutions:
Pouring experiment method for overall breaking force of steel wire rope, this method adopts the method for poured with epoxy resin to carry out tension test, and raw materials used composition is prepared in following composition and weight portion ratio: epoxy resin 8-15 part, ethylenediamine 0.2-0.6 part, dibutylester 3-8 part, silica sand 4-8 part, talcum powder 1-5 part.
Described test method comprises the steps:
1) take by weighing raw material by described part by weight, standby;
2) ready casting mold is heated to 60-70 ℃, pours in the mould, cable wire end is poured into a mould by the raw mix that described part by weight mixes;
3) will pour into a mould good cable wire end and keep waiting to solidify in 12-16 hour after, can carry out tension test.
Compared with prior art, the invention has the beneficial effects as follows:
A specification wire rope is opposed than test with two kinds of methods surplus five structures 30 such as 6V*34+NF, 6V*37S+NF, improve 10% with resin-cast is comparable with the whole rope of alloy pouring hoisting cable rupture pull force, the test figure of this method, can be more near the true rupture pull force of wire rope, more help the design of wire rope and determining of technological parameter, and raw materials cost is lower.
