Production technology of steel wire ring for tires

Abstract

The invention discloses a production technology of a steel wire ring for tires. The technology includes the steps of: steel wire unwinding, straightening, wiping cleaning, electric preheating, extrusion and rubber coating, cooling, coil forming, cutting, and isolation powder coating. During isolation powder coating, the surface of a shaped steel wire ring is coated with isolation powder through a coating powder conveyor so as to prevent sticking of the rubber coated shaped steel wire ring. The coating powder conveyor comprises a conveyer belt with a flannelette surface, and a roller above the conveyer belt. The isolation powder is disposed in the roller, the surface of which is provided with uniformly distributed holes and is wrapped by flannelette. The new technological method provided in the invention for a steel wire ring production process improves the steel wire ring sticking problem in current steel wire ring production. The employment of the flannelette equipped conveyer belt and the roller that make movement in opposite directions to coat the steel wire ring for tires with powder uniformly, and the efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of tire production and manufacturing, in particular to the technical field of tire casing production and manufacturing, and in particular to the manufacturing process of a steel traveler in casing building. Background technique [0002] The tire is mainly composed of a tire, an inner tube, and a pad, and the tire is an important part of the tire. The outer tire is mainly composed of inner surface rubber, cord fabric, tread rubber and steel traveler, and the steel traveler is an important part of the outer tire. Now the traveler forming methods generally include acid treatment traveler forming and acid-free treatment traveler forming. The acid-free treatment traveler forming process is: steel wire guide, straightening, wiping disc, electric preheating, extruder (covered) Glue), traction machine cooling roller, storage device (storage steel wire), rolled into coiled coil, formed steel traveler, cutting, count...

AI Technical Summary

Problems solved by technology

[0003] In this technological process, the most important problem is: after the steel wire is coated with rubber, in the process of stacking due to the viscosity of the rubber itself, the rubber-coated steel traveler is bonded together, which is used for tire production. Blank forming brings inconvenience to work and even affects tire quality

One of the current measures to solve this problem is to ask a special person or a forming worker to separate the bonded traveler. This method has low work efficiency and increases production costs. At the same time, artificially separating the bonded traveler will make the already The rubber covering the traveler falls off and exposes the steel wire, which affects the quality of the tire

There is also a method to reduce the viscosity of steel wire glue by changing the rubber compound formula, but this cannot guarantee the rubber coverage of the steel wire after molding, so the quality of the tire cannot be guaranteed
