Background

And a straightener is arranged on a cradle inside the steel cord internal take-up stranding machine tool, and each performance index of the steel cord is adjusted to finally obtain the steel cord with the performance index meeting the requirement. The working principle of the straightener is to use a plurality of slotted bearings, i.e. press rollers to squeeze the steel cord and to deform the steel cord.

Because the straightener bearing is smaller, the received radial force is larger, and the straightener bearing runs in a protective housing, the air circulation is not smooth, the temperature of the straightener bearing is generally about 90 ℃, the service life of the bearing is shorter, the straightener bearing is easy to rotate inflexible and even clamp in the use process, and the steel cord and the bearing are hard ground, and the production of products with unqualified performance indexes such as hard bending, spring, torsion, wave and the like is realized.

The straightening device is arranged on a cradle of a stranding machine tool, flywheel discs are arranged on two sides of the straightening device, a steel cord runs in a pulley arranged on the flywheel discs, the flywheel discs rotate at a high speed during production, and a protective film can be formed outside the straightening device by the steel cord, so that when a fan is arranged outside the cradle to cool the straightening device, wind is difficult to blow onto the straightening device, and the cooling effect is poor.
