Abstract
The utility model discloses a fixing device for a whole steel-cored aluminum strand abruption experiment, which includes two fixed ends made of high-strength high-polymer materials and cast at the two ends of the steel-cored aluminum strand respectively. The fixing device has a simple structure and is convenient to operate, and the two fixed ends made of the high-strength high-polymer materials can stand high-strength stretching force, and easily satisfies the test strength requirement specified in the national standard of GB/T1179-2009 round concentric steel-cored aluminum strand.
Description
Technical field
The utility model relates to whole of a kind of steel-cored aluminium strand and breaks test fixtures.
Background technology
Whole pull-off force test of steel-cored aluminium strand is the project that manufacturer and power department must be tested; GB/T1179-2009 circle line twists in the steel-cored aluminium strand national standard with one heart to be stipulated; " when requiring to carry out the pull-off force test of steel-cored aluminium strand; should be able to bear the calculating that is not less than regulation specified stretching resistance 95%, and arbitrary single line all should not rupture.The pull-off force of steel-cored aluminium strand should through stretching be fixed on suitable degree of accuracy be at least ± 1% tension tester on the method for steel-cored aluminium strand survey.For ease of test, the two ends of steel-cored aluminium strand sample should make suitable termination.Load when duration of test, the pull-off force of steel-cored aluminium strand by one or more single line when twisted wire fracture take place is confirmed.If the fracture of single line occurs in apart from the 1cm of termination, and stretching resistance then can test when requiring less than the pull-off force of regulation again, can test at most 3 times.”
Generally, one is to use the steel pipe crimping to connect fixes, and presses interface that single aluminium wire fracture is arranged, and causes test failure to test again, and cost is high.Two are to use low-melting alloy to cast fixes; Because the adhesion adhesion of low-melting alloy and steel and aluminium is low, when pull-off force was tested, the fracture of single line occurred in apart from the 1cm of termination; And stretching resistance is less than the pull-off force requirement of regulation, and it is low to break the success of the test rate.
The utility model content
The utility model technical matters to be solved provides a kind of whole of steel-cored aluminium strand that can stand high-strength pulling force and breaks test fixtures.
In order to solve the problems of the technologies described above, the technical scheme that the utility model provided is: whole of a kind of steel-cored aluminium strand is broken test fixtures, comprises the fixedly termination of being processed by the high strength macromolecular material; Said fixedly termination is provided with two, two fixedly the termination cast in the two ends of steel-cored aluminium strand respectively.
Said fixedly termination is truncated cone shape; Said two fixedly the big nose circle of termination lay respectively at the outer end at the two ends of steel-cored aluminium strand.
After having adopted technique scheme; The utlity model has positive effect: the utility model is simple in structure; Easy to operate; Process by the high strength macromolecular material two fixedly the termination can stand high-strength pulling force, surpass GB/T1179-2009 circle line and twist the proof strength requirement of stipulating in the steel-cored aluminium strand national standard with one heart.

Embodiment
(embodiment 1)
See Fig. 1, present embodiment comprises fixedly termination 1.
Fixedly termination 1 is processed by the high strength macromolecular material.Fixedly termination 1 is provided with two, two fixedly termination 1 cast in the two ends of steel-cored aluminium strand respectively.Fixedly termination 1 is truncated cone shape.Two fixedly the big nose circle of termination 1 lay respectively at the outer end at the two ends of steel-cored aluminium strand.
The casting fixedly prescription of the high strength macromolecular material of termination 1 is: 90 parts of 100 parts of bisphenol A type epoxy resins, 35 parts of modified polyamide epoxy curing agents, 10 parts of simple function group epoxy active diluents, 2 parts of hexane diamine catalyzer, 2 parts of coupling agents, 0.5 part of organosilane foam-breaking agent, 40 parts of high fineness silica flour reinforcing agents and high fineness hydrate of aluminium tendering resistant agents.
The carbon fiber complex core aerial condutor is broken test method, may further comprise the steps:
1. aluminium wire and the steel wire with two terminations of steel-cored aluminium strand scatters, and be as shown in Figure 2.
2. two termination top casting high strength macromolecular materials that scatter at steel-cored aluminium strand form two fixedly terminations 1.Be specially: at first on the inwall of the steel die that is truncated cone shape, coat release agent, the structure of steel die such as Fig. 3 and shown in Figure 4; Then two terminations of scattering of steel-cored aluminium strand are put into steel die respectively, upwards place two terminations of scattering of steel-cored aluminium strand, and the little nose circle of steel die downwards, nose circle is upwards placed greatly; Casting high strength macromolecular material forms two fixedly terminations 1 in steel die then.
The compound method of release agent is: 10 parts of weighing polyvinyl alcohol PVA pulverulent solids, and put into 90 parts distilled water, and be heated to 65～75 ℃, fully stir, make pressed powder be dissolved into transparence liquid fully, being cooled to normal temperature can use.
3. after the high strength macromolecular material solidifies with two fixedly termination 1 cooperate with two circular stiff ends of tension tester respectively, and carry out tensile test.
Above-described specific embodiment; Purpose, technical scheme and beneficial effect to the utility model have carried out further explain, it should be understood that the above is merely the specific embodiment of the utility model; Be not limited to the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
