Problems solved by technology

All there is following shortcoming in these two kinds of methods: (1) two kinds of methods all need to carry out a large amount of experiments, and required time is long; (2) all are direct destruction to tire, and then cause a large amount of resource wastes; (3) two kinds of methods Both of these methods are judged only based on the temperature and foaming conditions of individual points inside the tire, rely heavily on the experience of technicians, and have more chance; (4) The safety factor of vulcanization time is usually large, resulting in waste of energy; (5) Tire Often in an oversulfured state, tire performance is not optimal
The first condition for this method to be realized is to form a credible database, and the database needs to be obtained by combining the simulation process and the actual vulcanization process, which is not operable

Embodiment approach

[0020] In the second step, input the tire structure design drawing, mold design drawing, thermodynamic parameters and vulcanization characteristic parameters of each material, establish the heat conduction differential equation of the vulcanization process, and calculate the temperature values ​​of each part of the tire in real time by solving the equation, and then according to The vulcanization kinetic model calculates the degree of vulcanization. The specific implementation method is as follows:

[0021] (1) According to the structural design drawing and mold design drawing of the tire (such as figure 1 and figure 2 shown) to determine the spatial position of each runner and each part of the tire, and then provide initial conditions for solving the temperature change of each part inside the tire. According to Fourier's basic law of heat conduction and the first law of thermodynamics, the three-dimensional transient heat conduction differential equation in cylindrical coo...

Abstract

The invention relates to a digital automatic control method for a tire vulcanization process. The pressure and the temperature of high temperature steam in a capsule and the pressures and the temperatures of high temperature steam and superheated water in the flow channel of a vulcanizer are controlled in real time during tire vulcanization according to the structural size of a tire, the vulcanization characteristics of a material, the structural size of a mold and the vulcanization process in order to achieve energy saving and optimal performances in the vulcanization process.

Description

technical field [0001] The invention relates to a digitalized automatic control method for a tire vulcanization process, which belongs to the tire vulcanization process. Background technique [0002] Tires are an indispensable part of a car, which has a great influence on the driving performance, handling stability and comfort of the car. The development of the automobile industry has higher and higher requirements on the quality and performance of tires. Improving the quality of tires requires not only improvements in structural design, material formulation, and finished product testing, but also in the manufacturing process. The manufacture of tires must go through complex processes, such as rubber mixing, tread rubber extrusion, cord calendering and cutting, tire molding and tire vulcanization, etc. In the tire manufacturing process, vulcanization is the last process, but also a crucial link, which is closely related to energy consumption, production efficiency and even...
