It should be noted that the terms or terms referred to in the embodiments of the present application may be mutually referred and are not described in detail.
The rubber member has excellent elasticity and damping characteristics, and can be applied to various fields. When the rubber part is manufactured, the rubber material needs to be vulcanized to obtain the rubber part.
In one example, when the rubber compound is vulcanized, a constant-temperature vulcanization mode is generally adopted, that is, the rubber compound is put into a mold for production after the mold is preheated to a specific temperature. However, in the constant-temperature vulcanization mode, the mold needs to be preheated first, and then the rubber material is put into the mold for production, so that a large amount of heat resources are wasted, and further, the waste of heat resources generated in the process of preparing the rubber part is caused. The waste of heat resources can be well reduced by using a variable-temperature vulcanization process to produce rubber parts, but because the temperature of rubber materials in a mold can change in real time and is influenced by the surrounding environment during variable-temperature vulcanization, and the vulcanization rules of the rubber materials which are met at different temperatures are different, how to describe the vulcanization relation of the rubber materials under the variable-temperature working condition and reasonably determine the mold opening time is difficult to realize in the prior art; in addition, the existing production mode is difficult to study the performance change of the rubber part under variable-temperature vulcanization production, and the optimization and intelligent development of the vulcanization molding process of the rubber part are limited.
The application provides a preparation method, a device, equipment and a system of a rubber part, and aims to solve the technical problems in the prior art.
The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

And the electronic device may obtain the vulcanization degree at each previous time, where the vulcanization degree at each previous time may be calculated by the method of the present application and stored in the electronic device.
102. And determining the vulcanization degree of the rubber material at the current moment according to the temperature of the rubber material at the current moment and the vulcanization degree of the rubber material at each moment before the current moment.
Illustratively, a functional relationship exists among the vulcanization degree of the rubber compound, the rubber compound temperature and the rubber compound vulcanization time, and the functional relationship is calculated in advance by the electronic equipment according to the method provided by the application. Wherein the functional relationship can be changed along with the change of the types of the rubber compounds, the types of the vulcanizing agents and the proportion of the rubber compounds to the vulcanizing agents. The above functional relationship is not changed when the compound and vulcanizing agent from which the rubber part is produced are not changed.
According to the temperature of the rubber compound at the current moment obtained in step 101 and the vulcanization degree of the rubber compound at each moment before the current moment, the vulcanization degree of the rubber compound at the current moment can be obtained through calculation. The frequency of the electronic device for obtaining the vulcanization degree of the rubber compound is related to the sampling frequency of the temperature sensor, and the sampling frequency of the temperature sensor is more than 100 hertz (Hz).

If the electronic device determines that the vulcanization degree of the rubber material at the current moment is smaller than the preset threshold, it is determined that the vulcanization of the current rubber material is not completed, and at this time, step 101 needs to be executed again. The preset threshold value may be changed according to the requirement of the rubber product, for example, the preset threshold value is 0.9.
It should be noted that, during the process of curing the rubber compound, steps 101 to 103 need to be repeated until a rubber member is obtained.

Before step 202 is executed (i.e., before the rubber member is prepared), a vulcanization function is first established, which represents the relationship among the vulcanization degree of the rubber compound, the vulcanization time and the vulcanization temperature, and is used for calculating the vulcanization degree of the rubber compound at the current moment in the preparation process of the rubber member.
In one example, the vulcanization curves of the rubber materials at different temperatures are different, the vulcanization curves represent the relationship between the vulcanization degree x and the vulcanization time T, that is, the second vulcanization relationship, the vulcanization relationship of the same rubber material at different temperatures is different, and the vulcanization curves of the rubber material at least at three temperatures T are obtained.
In one example, when the vulcanization degree x is a certain value, a certain relationship exists between the temperature and the vulcanization time, and the relationship between the temperature and the vulcanization time is different at different temperatures, for example, the vulcanization degree x is an arbitrary value of 0 to 1, when the vulcanization degree x is 0.2, the vulcanization degree x corresponds to four different relationships at four temperatures of 60 ℃, 90 ℃, 120 ℃ and 150 ℃, and by adjusting a preset fitting parameter E, the second vulcanization relationship at different temperatures can be subjected to superposition processing to obtain a third vulcanization relationship, which is recorded as a function z, and the calculation formula of the function z is:
wherein t is the vulcanization time, E is the natural base number, and E is the fitting parameter. From the function z it can be seen that the third vulcanization relation characterizes the relation between time and temperature.
Further, it can be known from the above that each vulcanization degree x corresponds to a function z, the vulcanization degrees x at different temperatures are taken as abscissa, the overlapped function z is taken as ordinate, curve fitting is performed, and a fitted function z (x) which is a vulcanization function can be obtained, and it is apparent that the vulcanization function represents a relationship between vulcanization time and vulcanization temperature and vulcanization degree, and the fitting correlation degree in this embodiment is greater than 0.95.

In one example, step 202 specifically includes: acquiring the temperature value of the rubber material at the key position of the rubber piece detected by at least one temperature sensor at the current moment; and obtaining the temperature of the sizing material at the current moment according to the average value of the temperature values.
For example, to prepare a rubber part based on the system provided in fig. 7, it is not necessary to first heat the mold 1, and after the glue has been placed in the mold 1, the electronic device 7 starts heating the glue in the mold 1. The electronic equipment 7 acquires the temperature of the sizing material in real time through the temperature sensor 5, one or more temperature sensors 5 can be arranged in the system to monitor the temperature of the sizing material, and when the system only has one temperature sensor 5, the electronic equipment 7 can directly acquire the temperature measured by the temperature sensor 5; when the system has a plurality of temperature sensors 5, the electronic device 7 may obtain the temperature measured by each temperature sensor 5, may directly calculate an average value of the obtained temperature data as the temperature of the sizing material at the current time, and may also calculate an average value after removing the maximum value and the minimum value in the temperature data as the temperature of the sizing material at the current time.

In one example, step 203 specifically includes: and aiming at the adjacent moment in each moment, obtaining a first vulcanization relation of the previous moment in the adjacent moments according to the vulcanization degree of the previous moment in the adjacent moments and a preset vulcanization function.
Illustratively, the vulcanization function z (x) obtained in step 201 is derived to obtain z '(x), and z' (x) represents a first vulcanization relation corresponding to the vulcanization degree x, and the vulcanization degree x at the previous time in the adjacent time is compared with the vulcanization degree x at the previous time1Substituting into the derivative function of the preset sulfuration function to obtain a first sulfuration relation z '(x') of the previous time in the adjacent time1)。
204. And determining the vulcanization degree of the rubber material at the current moment according to the temperature of the rubber material at the current moment, the vulcanization degree of each moment before the current moment and the first vulcanization relation of each moment before the current moment.
In one example, the compound has a cure level at the present time of
Wherein T (t) is the temperature of the rubber compound at the current time t, E is the preset fitting parameter, E is a base number, and z' (x)n) Is the first vulcanization relation at the nth time among the times, xnThe vulcanization degree at the nth time in the times is obtained; Δ t is the interval time between adjacent moments in the moments; i is the number of each moment, and i is a positive integer greater than or equal to 0; n is a positive integer of 0 to i.
For example, assuming that the initial vulcanization degree of the compound is 0, according to the above calculation formula of the vulcanization degree of the compound at the present moment:
when i is equal to 0, the data is transmitted,
when the value of i is 1, the value of i,
when the value of i is 2, the ratio of i to i is,
