Cord residual torsional force matches somebody with somebody case test device.
Background technology
Steel cord is to develop product the most wide in rubber framework material, and production difficulty is maximum in metallic article
Product.Definition of the international synthetic fibers standardization office in a standard to steel cord be：" it is made up of two or more than two steel wires
, the structure that either combination by stock and stock or the combination by stock and silk are formed.Steel cord is made of high-quality high-carbon steel
Surface be coated with brass and with specific use thin gauge steel thread or rope.It is mainly used in tyres for passenger cars, light truck wheel
Tire, heavy type truck tyre, heavy equipment tire and aero tyre and other rubber framework materials.Made using steel cord
For the radial made by reinforcing material have service life is long, travel speed is fast, puncture-resistant, elasticity are good, safety and comfort,
The advantages that saving fuel.
Steel cord is electroplated by multi pass drawing and heat treatment in process of production, and generation is a large amount of during twisting
Residual stress, general finished product steel cord judge the direction of residual stress and size using the Residual torsion for detecting 6 meters, then pressed
Cased according to certain algebraical sum, to ensure tire plant after calendering, steel cord offset plate severing is smooth, meets that rubber plant is automatic
Change joint production requirement.But the new technology for a steel cord new product or production judges whether vanning is reasonable at present,
Severing can just know again after tire plant calendering, and experiment Period Process length, material waste is big, and experimentation cost is high.
The content of the invention
To solve above-mentioned technical matters, the utility model provides a kind of residual torsion of steel cord and matches somebody with somebody case test device, can
The problems such as effective experiment Period Process that solves is grown, and material waste is big, and experimentation cost is high.
