Description
Technical field
The present invention relates to a kind of verifying attachment, specifically a kind of bead wire ring device for testing strength.
Background technique
The wire loop of tire is one of main stressed member of tire, and wire loop usually divides three types by cross sectional shape:
Rectangle, hexagon and circle.Usual stream in tire manufacturing plant is only to the raw material of wire loop --- i.e. the breaking strength of individual wire into
Line sampling is examined, and wire loop is formed by more steel wire windings, it is considered that:
Theoretical wire loop intensity=individual wire intensity × steel wire radical
Wire loop actual strength is often below theoretical value, because the stress of more steel wires is non-uniform, the knot of this and wire loop
Whether the factors such as kiss-coating are related for configuration formula, steel wire.Usually examine whether wire loop meets by bursting pressure test of tire
It is required that designer would generally rule of thumb amplify on the basis of theoretical wire loop intensity certain to ensure that wire loop is met the requirements
Safety multiple.Since the actual strength of wire loop has certain dispersibility, even if considering safety multiple, it also inevitably will appear steel wire
The insufficient or superfluous situation of loop material.If inspection and statistical analysis can be sampled to the breaking strength of wire loop, to design
The material utilization amount that person rationally designs wire loop is very helpful.
With going deep into for Tire production division of labor and lines of specialities cooperation, some components will be provided in the form of outsourcing by supplier, such as:
The particularity of circular steel wire ring, structure makes it more suitable for outsourcing.How to the breaking strength of Covered with Angles wire ring (as key
Index) it carries out an acceptance inspection, such a wire loop strength test device will be needed.
In short, needing to be sampled inspection to the breaking strength of wire loop in the development of tire, production and sub-contract management
It tests, to verify whether to reach prescribed requirement.Therefore need to research and develop a kind of wire loop strength test device, to realize to wire loop
Breaking strength is examined.
Summary of the invention
The purpose of the present invention is in order to overcome the deficiencies of the prior art, provide a kind of bead wire ring device for testing strength.This
Kind verifying attachment can realize the inspection of wire loop breaking strength on pressure testing machine the pulling force that pressure conversion is to wire loop
Survey, and upper fixture and lower fixture can automatic vertical centering, structure is simple, compact, convenient and practical.
Realizing the technical solution of the object of the invention is:
A kind of bead wire ring device for testing strength, including upper bed-plate and lower bottom base, lower bottom base are located at below upper bed-plate, upper bed-plate
One side directed downwardly is equipped with the first support plate and the second support plate of vertical upper bed-plate bottom surface, and the face of lower bottom base upward is equipped with vertical
The third support plate and the 4th support plate of lower bottom base upper surface, the first support plate and the second support plate are located at third support plate and the
Between four support plates, upper fixture and lower fixture are equipped between the first support plate and the second support plate, lower fixture is located under upper fixture
Side, upper pin sequentially pass through third support plate, the first support plate, upper fixture, the second support plate and the 4th support plate, lower bearing pin according to
Secondary to pass through the first support plate, lower fixture and the second support plate, upper fixture is identical as structure, specification, the shape of lower fixture and in half
Annulus shape, upper fixture and lower fixture combination are equipped with protrusion at the top of the arc of upper fixture and lower fixture inner wall at annulus.
Upper fixture and lower fixture combination at annulus outer wall be equipped with groove, groove is for fixing wire loop.
It is equipped with gap between upper fixture and lower fixture, may be implemented to upper fixture and lower fixture combination into circular scaling,
To be packed into wire loop.
This verifying attachment can realize that wire loop is pulled apart by force on press machine the pulling force that pressure conversion is to wire loop
The detection of degree, and upper fixture and lower fixture can automatic vertical centering, structure is simple, compact, convenient and practical.
Detailed description of the invention

Fig. 2 is sectional view at A-A in Fig. 1.
In figure, the lower fixture of 1. 2. upper pin of upper bed-plate 1-1. the first support plate the second support plate of 1-2., 3. upper fixture 4.
5. 6. the 4th support plate of lower bottom base 6-1. third support plate 6-2. of lower bearing pin, 7. wire loop.
Specific embodiment
The contents of the present invention are further elaborated below with reference to embodiment and attached drawing, but are not to limit of the invention
It is fixed.
Embodiment:
Referring to Fig.1, Fig. 2, a kind of bead wire ring device for testing strength, including upper bed-plate 1 and lower bottom base 6, lower bottom base 6 are located at upper
1 lower section of pedestal, the one side directed downwardly of upper bed-plate 1 are equipped with the first support plate 1-1 and the second support plate 1- of vertical 1 bottom surface of upper bed-plate
2, the face of lower bottom base 6 upward is equipped with the third support plate 6-1 and the 4th support plate 6-2 of vertical 6 upper surface of lower bottom base, the first support
Plate 1-1 and the second support plate 1-2 are between third support plate 6-1 and the 4th support plate 6-2, the first support plate 1-1 and second
Upper fixture 3 and lower fixture 4 are equipped between support plate 1-2, lower fixture 4 is located at 3 lower section of upper fixture, and upper pin 2 sequentially passes through third
Support plate 6-1, the first support plate 1-1, upper fixture 3, the second support plate 1-2 and the 4th support plate 6-2, lower bearing pin 5 sequentially pass through
First support plate 1-1, lower fixture 4 and the second support plate 1-2, upper fixture 3 is identical as structure, specification, the shape of lower fixture 4 and is in
Semicircular ring shape, upper fixture 3 and lower fixture 4 are combined into annulus, are equipped at the top of the arc of upper fixture 3 and lower 4 inner wall of fixture convex
It rises.
The annulus outer wall that upper fixture 3 and lower fixture 4 are combined into is equipped with groove.
Gap is equipped between upper fixture 3 and lower fixture 4.
By upper pin 2 from third support plate 6-1, the first support plate 1-1, upper fixture 3, second support plate 1-2 and the 4th
It takes out, lower bearing pin 5 is taken out from the first support plate 1-1, lower fixture 4 and the second support plate 1-2, wire loop in fagging 6-2
