Description
Technical field
The equipment that the invention belongs to fixing packing material, specifically one quick-setting metal and non-metal wire at normal temperaturesWhen property material bears tensile load, two ends pouring type is prepared the method for anchor block.
Background technology
According to up-to-date round line concentric gallows empty conductor standard GB/T1179-2008 regulation, in the type approval test of steel-cored aluminium strandThe pull-off force test that comprises conductor, its specific descriptions are as follows: it is suitable that (1) should make for ease of the two ends of test lead sampleTermination. The pull-off force of duration of test wire is determined by the load in the time that fracture occurs one or more single line of twisted wire. If singleThe fracture of line occurs in apart from the 1cm of termination, and regulation pull-off force require time, can again test, can try at mostTest 3 times. (2) stress-strain testing should use the end fitting of demanding party's accreditation, for example crimping, epoxide resin type or low melting pointAlloy-type, before manufacturing terminal part device, single line should be not loose, cleans or grease. When mounting end device, should not cause listAny of line becomes flexible, because this can change the load-deformation curve of wire.
The sample end construction method for making sample of this test at present can adopt low-melting alloy cast and crimping sleeve. But these two kindsMore easily there is stress concentration phenomenon in method, breakaway poing appears near termination, and success of the test rate can not ensure. Low-melting alloyType termination shortcoming is presented as the about 75 DEG C of left and right of low-melting alloy fusing point, and when cast, sample and alloy molten solution exist the temperature difference, sampleThe lower stress curve of the effect of expanding with heat and contract with cold changes in addition, and under heat affecting effect, sample mechanical performance changes, and bears stretchingLoad-carrying ability declines, and produces stress and concentrates. Crimp type termination is in the time of working pressure machine crimping sleeve, and pressure selection affects crimping matterAmount. Pressure sleeve pipe less than normal and wire, in conjunction with defective tightness, produce slippage in test. The excessive conductor deformation of pressure is excessive, and formation is subject toPower weak spot, fracture generally appears at this point. Two kinds of modes of low-melting alloy and crimping sleeve are prepared cable pull-off force test specimenTime, it is particularly serious that heavy in section sample is affected by this.
