The invention discloses a preparation method of a circular-section steel wire ring for a
radial tire. According to the preparation method, a steel wire ring with a
circular section is formed by winding a single attached steel wire on a concave semicircular tile of a steel wire ring winding disc on a steel wire winding device, in the winding process, the coiling of steel wires, the horizontal wire arrangement among the steel wires, the up and down wire
tripping among the steel wires and the total winding amount of the steel wires are respectively controlled by
servo systems correspondingly arranged on the steel wire winding device, all the
servo systems are connected with a PLC (
Programmable Logic Controller) through lines, thus realizing the
automatic control; a circular-section steel wire ring
production line is composed of the steel wire winding device and a steel wire unwinding device, as well as a cloth roller wire cleaning device, a preheating device, an extruder, a traction, storage and cooling device, a prebending device and a steel ring wrapped winding device. According to the preparation method, the coiling, wire
discharge, wire
tripping and winding amount of the steel wires are controlled by the
servo systems with set parameters, and the preparation method has the characteristics of being precise for materials to take, close to wind, uniform for intervals, and stable for circular-section shape.
