Description
Technical Field
The invention relates to a testing device, in particular to a tire bead ring strength testing device.
Background
The bead ring of a tire is one of the main stress components of a tire, and is generally classified into three types by sectional shape: rectangular, hexagonal, and circular. In general, tire manufacturers only sample and test the raw material of bead rings, namely the breaking strength of a single steel wire, and the bead rings are formed by winding a plurality of steel wires, which is generally considered as follows:
theoretical bead ring strength=single wire strength×number of wires
The actual strength of the bead ring is often smaller than the theoretical value, because the stress of the plurality of steel wires is uneven, which is related to the structural form of the bead ring, whether the steel wires are glued or not, and the like. Whether the bead ring meets the requirement is usually checked through a tire burst pressure test, and in order to ensure that the bead ring meets the requirement, a designer usually amplifies a certain safety factor based on the theoretical bead ring strength according to experience. Because the actual strength of the bead ring has certain dispersibility, even if the safety factor is considered, the situation that the bead ring material is insufficient or excessive is unavoidable. If the breaking strength of the steel wire ring can be subjected to sampling inspection and statistical analysis, the method is helpful for a designer to reasonably design the material consumption of the steel wire ring.
With the penetration of the tire manufacturing industry's industry cooperation, some parts will be provided by suppliers in outsourced form, such as: the special structure of the circular bead ring makes the bead ring more suitable for being outsourced. How to accept the breaking strength (as a key index) of the outer-covered bead ring would require such a bead ring strength test device.
In summary, during the development, production and outsourcing of the tire, it is necessary to sample the pull-apart strength of the bead ring to verify whether the specified requirements are met. It is therefore desirable to develop a bead ring strength test apparatus to achieve a tear strength test for a bead ring.
