Description
Technical Field
The utility model relates to a tire manufacturing technical field especially relates to a tire belted layer forming die.
Background
At present, the truck tire is mainly an all-steel radial tire released by Michelin in the fifties of the twentieth century. The all-steel radial tire structure comprises a tire tread, base rubber, a belt ply, a tire body, soft triangles, hard triangles, bead filler wear-resistant rubber, sidewall rubber, an air-tight layer, an inner liner and the like. The rubber materials mainly comprise natural rubber, styrene-butadiene rubber, butyl bromide rubber and the like, and the framework materials mainly comprise steel wires, polyester cords and the like. Through the development of nearly 70 years, all-steel radial tires have obvious advantages in the aspects of performance, oil consumption and the like, and are widely popularized in the global range at present.
The stress of the tire in the rolling process is extremely complex, the functions of all parts are different, and the requirement is difficult to meet only by using one or two rubber materials, so that the tire structure evolves to supplement the parts mutually. All parts of the all-steel radial tire have different functions and different requirements on materials, for example, the tire side needs ultraviolet resistance, wear resistance, fatigue resistance and the like, and the air-tight layer has higher requirements on air tightness.
The belted layer is arranged between the tread and the tire body by steel wires according to different angles and is used for improving the supporting and stress parts of the tire. The main functions are as follows: firstly, the tyre body resists the centrifugal force, the outward convex phenomenon of the tyre crown caused by the centrifugal force is prevented, and the stable external diameter and the tyre circumference are ensured. Secondly, the desired shape of the tire footprint is controlled, thereby effectively providing grip/traction. Third, it provides rigidity required for the tire to oversteer and turn, and thus provides excellent handling. Fourthly, the invasion of foreign matters on the road surface is resisted.
Briefly, a belt is a tire component that is formed by arranging steel wires at an angle and extruding a rubber compound onto the surfaces of the steel wires. According to specification, type, service environment, bearing, speed and the like, the tire is designed into a structure with different belted layer numbers, different belted layer widths, different belted layer steel wire angles, different belted layer thicknesses and different belted layer steel wire thicknesses so as to meet the requirements of actual conditions.
At present, the production process of the rubber tire belt layer is complicated, as shown in fig. 1. Firstly, arranging a certain number of steel wires into a plurality of rows in an ingot room, entering a calender at a certain speed to attach rubber, and finally cutting a belt ply. Finally cutting the belt into belt components meeting the width and the angle, and attaching the belt components when the belt components are formed. The bias cutting process is complex and expensive in equipment and process, and also produces a large amount of leftovers, so that the manufacturing cost of the tire is increased, which is particularly prominent for engineering tires and giant tires.
The process lasts for nearly fifty years, the technical indexes are strictly controlled in the actual production, otherwise, the phenomena of uneven glue coating, steel wire leakage and the like can occur. However, unvulcanized rubber is in a semi-solid state, has high viscosity, and cannot fundamentally solve the problems, and the quality problems of air bubbles, steel wire leakage and the like often occur during the production of steel wire rubberizing parts. And the production process has the environmental protection problems of heavy metals, toxic and harmful substances and the like.
In the first step of the traditional process, shuttles (winding steel wires) are required to be regularly arranged on a support in a spindle room, thousands of shuttles are required to be arranged in the whole spindle room, each steel wire is led out by one shuttle respectively, hundreds of steel wires form a row according to a certain fixed interval, and the row of steel wires is drawn to a calender under the action of tensile force.
The process has hundreds of shuttles, one of which is problematic and directly affects the overall production schedule. And the disassembly and replacement are complicated, and special people are needed to manage the spindle houses. In particular, in order to prevent water mist generated on the steel wire from affecting the adhesive force between the rubber and the steel wire, the spindle room needs to be dried indoors and kept at a constant temperature, and the temperature is greatly higher than the outdoor temperature to be avoided. The harsh indoor operating environment consumes a large amount of energy, manpower and material resources, and the overall production cost of the tire is improved.
In the traditional process, rubber for wrapping the steel wire has high hardness and high viscosity, and can enter a calender after being reheated before rubber is attached, otherwise symptoms such as air bubbles, steel wire leakage and the like can occur. Generally, three open mills are arranged in front of a calender to complete rubber breaking, refining and the like of rubber compound, and the fluidity of the rubber compound is improved by heating.
The process involves complex equipment and requires about 5-10 people to complete the heat-refining and conveying of the rubber compound. Greatly increasing the difficulty of the operation. If various parameters of the sizing material in the hot-refining process have problems, the product quality and the production efficiency of the whole calendering line are directly influenced. Particularly, during the hot refining, a large amount of malodorous gas is generated by the heating of the rubber material, resorcinol and the like contained in the steel wire rubber formula are strong carcinogens, and are released into the air along with the heating of the rubber material, so that the operating environment of a workshop and the physical and mental health of workers are seriously affected, and rubber mixing workers belong to special workers, and the risks of cancer and infertility are increased if the rubber mixing workers work in the operating environment for a long time. In addition, the investment of a calender and an open mill is large, and the maintenance cost of equipment is extremely high.
The steel wire for a tire is formed by twisting a plurality of thin steel wires into a plurality of strands. There are large gaps between each strand of steel wire. The adhesion of rubber to steel cords is a critical problem that plagues tire durability. At present, copper is mainly plated on the surface of a steel wire, the chemical reaction between cobalt salt and copper in a formula is used for improving the performance, and the rolling technology is mainly characterized in that rubber materials are attached to the surface of the steel wire through extrusion of a die orifice of a die plate, and the semi-solid state of rubber is poor in flowability even at 100 ℃, so that the rubber is difficult to permeate into a gap inside the steel wire, cannot completely cover the surface of a single thin steel wire, and cannot be chemically bonded with the copper on the surface. Failure to achieve adhesion due to various factors such as penetration, encapsulation, chemical reaction temperature, etc. can lead to early failure of the tire. In addition, copper plating on the steel wire and the addition of cobalt salt in the rubber cause more environmental protection problems in the production of raw materials, the manufacture of tires and the use process.
In the prior art, after the glue is attached, the cord fabric enters the bias cutting process, and because the angles of steel wires in a belt ply are different and are all 0-180 degrees, more leftovers can be produced in the bias cutting process, the larger the angle is, the larger the size of the leftovers is, and the higher the loss cost is. In addition, decide and need only splice the belted layer after accomplishing and just can use, the concatenation can cause certain influence to the quality of product. The problem that tires with more specifications cannot be developed due to the limitation of the cutting angle and the cost of the equipment is limited, the development and expansion of tire factories are limited, and certain influence is shown in the age when tires compete to enter the micro-profit era.
