Abstract
The invention discloses a positioning gauge length cord thread marking line which comprises a cord thread line and an induction strip, wherein the induction strip is wound on the periphery of the radial circumference of the cord thread line in a 360-degree mode, and the first circle wound by the induction strip is tightly wound on the outer circumference of the cord thread line. In the process of a tensile test, even if the cord thread is twisted while being stretched, the sensing strip is wound on the whole radial circumference of the cord thread in 360 degrees, and no sensing point is lost no matter how the cord thread is twisted, so that the optical extensometer can accurately sense the cord thread elongation displacement determined by the sensing point, and the tensile test is ensured to be continuously carried out.
Description
Technical field
The present invention relates to a kind of cord tag line, relate in particular to a kind of location gauge length cord tag line.
Background technology
Cord as tire framework material, need to have enough intensity, and a tires need to be selected the cord of different-stiffness characteristic in tire design, therefore need to test or test cord, and the location gauge length of cord is comparatively conventional a kind of test method.Locate at present the location gauge length that contact extensometer and optics extensometer are arranged that gauge length adopts, the contact extensometer because shearing force can cause the inaccurate of result, does not therefore generally adopt the contact extensometer when doing cord location gauge length when doing cord location gauge length.And when adopting the optics extensometer to position gauge length to cord, need to stick fluorescent paper on cord to be tested, because cord 6 is very thin, so paste at present the very little fluorescent paper 7 of the general intercepting of mode of fluorescent paper, it is attached on cord cylindrical outer wall 61 parts, in process of the test, the light that on the infrared induction element senses cord of optics extensometer, fluorescent paper sends and determine the location gauge length, as shown in Figure 1.due in doing location gauge length process, cord is except being elongated, also can be reversed, therefore when the fluorescent paper 7 on cord is rotated to parallel with the infrared light of sensing element or is stopped by cord, sensing element can not continue to sense the location gauge length of fluorescent paper mark, thereby cause stretching experiment to proceed, can only again paste fluorescent paper and repeat to begin new test, but still can cause because of the appearance of the problems referred to above again stopping experiment in experimentation, not only waste cord, and the efficient of reduction test, the more important thing is experiment always be difficult to carry out, can't learn the performance of cord.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of location gauge length cord tag line, is convenient in process of the test accurately induction cord induction point, guarantees that sample plot proceeds.
The present invention is achieved through the following technical solutions: the present invention a kind of location gauge length cord tag line, comprise cord bar and induction bar, that induction bar 360 degree is wound in the radial circumference of described cord bar is peripheral, and the first lap that the induction bar is wound around is the excircle that closely is wound in the cord bar.
Preferably, the induction bar number of turns scope that is wound in cord bar excircle is one to five circle.
Preferably, to be 1 degree to 360 degree around the angle of excircle arbitrarily angled for the induction bar last lap that is wound in cord bar excircle.
Preferably, the diameter of induction bar the second circle of being wound in cord bar excircle arbitrary circle to the 5th circle is greater than the diameter of first lap.
Preferably, the second circle that the induction bar is wound in cord bar excircle cross section perpendicular to the cord axis of arbitrary circle to the 5th circle is ellipse, triangle, quadrilateral, or pentagon.
Preferably, the induction bar of cord has two.
Compared with prior art, the present invention locates gauge length cord tag line, because the induction bar of cord is whole radial circumference around the cord bar, has increased induction area.In the gauge length process of location, although cord is reversed when stretching, the induction bar is the whole radial circumference that 360 degree are wound in the cord bar, no matter how cord reverses all can not lose induction a little, therefore the optics extensometer can accurately sense the cord elongation displacement that induction point is determined, guarantees proceeding of stretching experiment.

Embodiment
Please refer to shown in Figure 2, a kind of gauge length cord tag line 1 of locating of the present invention comprises cord bar 11, is wound in the induction bar 13 on cord bar 11, and in embodiments of the present invention, induction bar 13 is the induction points as the infrared induction of optics extensometer, preferably, induction bar 13 is fluorescent papers.Two of the up and down induction point of being determined by induction bar 13 is arranged respectively on cord bar 11, and the fluorescent paper of making induction bar 13 is shaped as the 360 degree hollow cylinders that are wrapped in cord bar 11 periphery.In the present embodiment, the slightly larger in diameter of induction bar 13 is in the diameter of cord bar 11.
When making the present invention a kind of location gauge length cord tag line 1, two ends at cord bar 11 certain-lengths closely are wound around fluorescent paper respectively a circumferential circle of cord bar 11, make fluorescent paper closely be attached to cord bar 11 excircles, and guarantee that induction point can not move up and down, then fluorescent paper is wound around the second circle on this basis, the diameter of the second circle fluorescent paper makes induction area increase greater than the diameter of cord bar 11.Be used for location gauge length process as example take the present invention a kind of location gauge length cord tag line 1, although cord 1 is also reversed when stretching, but be wound in the whole radial circumference of cord bar 11 due to induction bar 13, during tensile cords 1, no matter how cord 1 reverses all can not lose induction a little, therefore the optics extensometer can accurately sense the elongation displacement of the definite cord 1 of induction point, guarantees proceeding of stretching experiment.In addition, fluorescent paper is wrapped on cord bar 11 can be not limited to two circles, can three to five circle, even more multi-turn, be appreciated that it is complete winding 360 degree that last lap might not require, and can be wound around any number of degrees of 1 degree to 360 degree.
Certainly, the induction bar 13 of cord 1 of the present invention can be also to be wound around cord bar 11 radially the hollow elliptical cylinder, triangular prism, quadrangular, pentagonal prism, irregular polygon prism etc. of whole circumference, the cross section perpendicular to the cord axis of namely responding to bar 13 is ellipse, triangle, quadrilateral, pentagon or other are irregularly shaped, locate in gauge length as long as can guarantee, no matter how cord bar 11 reverses, and all can sense induction bar 13 and get final product.Further, induction bar 13 can be the radially whole periphery that fluorescent paper directly closely is wound in cord bar 11, the fluorescent paper of making induction bar 13 can only be wound around cord bar 11 1 circles, also can closely be wound around two to five circles, multi-turn even more, be appreciated that it is 360 complete degree that last lap might not require, and can be wound around 1 any number of degrees of spending in spending to 360.
In the present invention, the number of induction bar 13 is 2, and still according to the needs of different tests, the number of induction bar 13 can be not limited to 2.
