Description

Technical Field

[0001] The present invention relates to the technical field of cutting fluids, and relates to, but is not limited to, a method, device, equipment and storage medium for calculating the stability of emulsions in high-speed steel cutting fluids. Background Art

[0002] An emulsion is a common water-based cutting fluid, which is composed of oil, water, emulsifiers and other additives. This cutting fluid is widely used in machining because it combines the lubricating properties of oil and the cooling properties of water, and forms a stable dispersion system by adding specific emulsifiers and other functional additives. This liquid is widely used in the metal processing process as a cooling and lubricating medium to assist operations such as cutting and grinding. According to its physical form and application characteristics, emulsions can be classified into the following types: Conventional emulsions: mainly composed of oil, containing a relatively large amount of base oil, suitable for general metal processing requirements. Microemulsions: the oil droplets are very small (usually less than 0.1 microns), with better transparency and chemical stability, suitable for high-speed cutting and precision machining. Semi-synthetic emulsions: between traditional emulsions and fully synthetic cutting fluids, combining the advantages of both, retaining a certain degree of lubricity and having good cooling performance. Fully synthetic cutting fluids: completely free of mineral oil, mainly composed of various chemical compounds, especially suitable for occasions with high environmental protection requirements and processing environments that require extremely high cleanliness.

[0003] Emulsions are widely used in various mechanical manufacturing industries, especially indispensable in the fields of automotive manufacturing, aerospace, and mold manufacturing. They not only help improve processing efficiency and quality, but also effectively protect machine tools and extend tool life. In addition, in some special cases, such as the processing of difficult-to-machine materials (such as titanium alloys and stainless steels), the selection of a suitable emulsion is particularly important.

[0004] During the machining process, during long-term use, due to factors such as temperature changes, cutting speed, and iron chip content, emulsions are prone to stratification, thus reducing their service life and efficiency. Therefore, their stability under different conditions is of great significance for finding effective methods to enhance the stability of emulsions. Summary of the Invention

[0031] The following describes an exemplary application of the stability calculation device for the emulsion in the high-speed steel cutting fluid according to the embodiments of the present invention.

The terminal and the server can be directly or indirectly connected through wired or wireless communication methods, which are not limited in the embodiments of the present invention. Below, an exemplary application will be described when the stability calculation device for the emulsion in the high-speed steel cutting fluid is implemented as a server.

[0032] The embodiments of the present invention provide a method for calculating the stability of an emulsion in a high-speed steel cutting fluid. Refer to Figure 1 , Figure 1 which is a schematic flowchart of the method for calculating the stability of the emulsion in the high-speed steel cutting fluid provided by the embodiments of the present invention, and will be described in conjunction with Figure 1 the steps shown.

[0033] Step S110, obtain relevant data affecting the stability of the emulsion; the relevant data includes extreme pressure agent and emulsifier reaction data, first emulsion performance data, and second emulsion performance data.

[0034] Here, the first emulsion performance data refers to the performance data of the emulsion at different working temperatures; the second emulsion performance data refers to the performance data of the emulsion at different pollutant contents.

[0035] In some embodiments, the extreme pressure agent and emulsifier reaction data refers to the interaction between the two under different conditions, and this interaction has a key impact on the stability of the emulsion. Different types and proportions of extreme pressure agents and emulsifiers can be mixed and reacted under set conditions such as temperature, pressure, and time, and the phenomena and parameters during the reaction can be recorded, such as the composition of the reaction product, reaction heat, reaction rate, etc.

[0036] In some embodiments, the first emulsion performance data may at least include the pH value (acidity and alkalinity), surface tension, particle size distribution, and demulsification time of the emulsion, and all these data can reflect the influence of temperature on the stability of the emulsion.

[0037] In some embodiments, the second emulsion performance data refers to the performance data of the emulsion under different pollutant contents. After pollutants such as metal chips, dust, and microorganisms are mixed into the emulsion, its performance will change, which can reflect the influence of pollutants on the stability of the emulsion.

[0038] Step S120: Respectively perform feature extraction on the extreme pressure agent and emulsifier reaction data, the first emulsion performance data, and the second emulsion performance data, and correspondingly obtain the extreme pressure agent and emulsifier reaction features, working temperature features, and pollutant features.

[0039] In some embodiments, the extreme pressure agent and emulsifier reaction features refer to extracting information such as the reaction degree (e.g., reactant conversion rate), reaction rate (change in reactant concentration per unit time), and reaction equilibrium constant of the extreme pressure agent and emulsifier.

[0040] In some embodiments, the working temperature features refer to finding the key indicators of the change in emulsion performance in different temperature ranges. For example, within a certain temperature range, the change rate of the pH value and the change trend of the surface tension.

[0041] In some embodiments, the pollutant features refer to extracting the correlation features between the pollutant types, contents, and the change in emulsion performance. For example, when the content of a certain pollutant increases, the shortening ratio of the demulsification time of the emulsion.

[0042] Step S130: Calculate the first stability influence value based on the extreme pressure agent and emulsifier reaction features.

[0043] In the embodiments of the present invention, the first stability influence value is calculated by the following formula:

[0044] S 反应 = a1R + b1P + c1t + d1RP + e1Rt + f1Pt, where a1, b1, c1, d1, e1, f1 are weight factors affecting the first stability influence value; R is the reaction rate; P is the concentration of the reaction product, and t is the reaction time.

[0045] Step S140: Calculate the second stability influence value based on the working temperature features.

[0046] In the embodiments of the present invention, the calculation formula of the second stability influence value is expressed as: S 温度= g1T + h1ΔT / Δt + i1TΔT / Δt, where g1, h1, and i1 are adjustment coefficients for regulating temperature and temperature change rate; T is the working temperature; and ΔT / Δt is the temperature change rate.

[0047] Step S150: Calculate a third stability influence value based on the pollutant characteristics.

[0048] In an embodiment of the present invention, the calculation formula of the third stability influence value is expressed as: S 污染 = j1F + k1O + l1FO + m1F 2 + n1O 2 , where j1, k1, and l1 are weighting factors for adjusting the negative impact of pollutants; m1 and n1 are correction parameters for data normalization; F is the iron filings content; and O is the content of other pollutants.

[0049] Step S160: Determine an overall stability calculation value of the emulsion based on the first stability influence value, the second stability influence value, and the third stability influence value.

[0050] In an embodiment of the present invention, the calculation formula of the overall stability calculation value is expressed as: Q = f × (S 反应 + S 温度 + S 污染 ), where f is a global correction factor.

[0051] The method for calculating the stability of the emulsion in the high-speed steel cutting fluid provided by the embodiment of the present invention obtains relevant data affecting the stability of the emulsion; the relevant data includes extreme pressure agent and emulsifier reaction data, first emulsion performance data, and second emulsion performance data; respectively extracts features from the extreme pressure agent and emulsifier reaction data, the first emulsion performance data, and the second emulsion performance data, and correspondingly obtains extreme pressure agent and emulsifier reaction characteristics, working temperature characteristics, and pollutant characteristics; calculates a first stability influence value based on the extreme pressure agent and emulsifier reaction characteristics; calculates a second stability influence value based on the working temperature characteristics; calculates a third stability influence value based on the pollutant characteristics; and determines an overall stability calculation value of the emulsion based on the first stability influence value, the second stability influence value, and the third stability influence value. In this way, on the one hand, the present invention can reduce errors in traditional methods through a more accurate mathematical model, improving the accuracy of stability evaluation; on the other hand, the present invention optimizes the calculation process and speeds up the evaluation speed; thirdly, the present invention has stronger predictability and can identify potential problems before the emulsion fails, helping to take measures in advance; at the same time, the present invention reduces the impact on the environment, helps to improve the efficiency, accuracy, and economy of emulsion stability evaluation, and further optimizes the use and maintenance of cutting fluid.

[0052] In some embodiments, the method further includes the following steps S210 to S240:

[0053] Step S210, comparing the overall stability calculation value within any time period with a preset stability threshold.

[0054] Step S220, if the overall stability calculation value is greater than the preset stability threshold, it is determined that the stability of the emulsion is abnormal within the current time period, and the number of abnormalities of the overall stability calculation value is compared with a preset number threshold.

[0055] Step S230, if the number of abnormalities exceeds the preset number threshold, determine the data that causes the abnormality of the overall stability calculation value.

[0056] Step S240, if none of the multiple data is abnormal, change the extreme pressure agent and emulsifier reaction data, the first emulsion performance data, and the second emulsion performance data, and recalculate the overall stability calculation value until the overall stability calculation value is less than the preset stability threshold.

[0057] In some embodiments, the method further includes:

[0058] Perform a double integral on the calculation formula of the first stability influence value to obtain the integrated calculation formula, expressed as:

[0059] Perform a double integral on the calculation formula of the second stability influence value to obtain the integrated calculation formula, expressed as:

[0060] Perform a double integral on the calculation formula of the third stability influence value to obtain the integrated calculation formula, expressed as:

[0061] Next, an exemplary application of the embodiments of the present invention in an actual application scenario will be described.

[0062] In the long-term use process of the present invention, due to the influence of factors such as temperature change, cutting speed, and dilution ratio, the emulsion is prone to stratification, resulting in the weakening of the lubricity, cooling performance, and rust prevention performance of the cutting fluid, thereby reducing the working efficiency and service life of the cutting tool and the implement.

[0063] To solve the problems existing in the prior art, the present invention proposes a new calculation method to calculate the use stability of the emulsion under different conditions through a mathematical model to obtain the emulsion stability during the use of the cutting fluid.

[0064] It should be noted that the stability of the emulsion in the cutting fluid is mainly affected by three factors: the reaction between extreme pressure agents and emulsifiers, the working temperature, and pollutants. By changing the above three factors, the optimal process conditions can be determined.

[0065] It should be noted that during the cutting process of high-speed steel materials, the temperature is 580 - 600 °C. This is because as the temperature rises, the base oil and other components will undergo thermal expansion, resulting in a decrease in the viscosity of the emulsion. The lower viscosity may weaken the strength of the oil-water interfacial film, making the emulsion more likely to stratify or demulsify.

[0066] It should be noted that extreme pressure agents are mainly used to provide additional lubrication performance, especially under high load and high temperature conditions, to prevent direct contact between metal surfaces and cause wear or adhesion.

[0067] In addition, metal chips such as iron chips and aluminum chips generated during the processing, as well as solid particles such as dust and sand grains from the environment, will increase the viscosity of the emulsion, hinder the effective circulation of the coolant, and lead to increased tool wear. Certain metals (such as copper and zinc) may react chemically with the components in the emulsion to form insoluble precipitates, destroying the uniformity and stability of the emulsion. At the same time, metal chips and other organic substances provide nutrients for microorganisms, promoting the growth of bacteria and fungi, and further deteriorating the quality of the emulsion.

[0068] The present invention provides a calculation method for the emulsion stability of cutting fluid, and the specific steps are as follows:

[0069] In order to improve the stability of the emulsion under different conditions, the following steps are taken for data collection:

[0070] Step 1, collect the reaction data of extreme pressure agents and emulsifiers under different formulations, the performance data of the emulsion under different working temperatures, and the performance data of the emulsion under different pollutant (iron chip) contents.

[0071] Step 2, perform feature extraction on the collected data above to obtain respectively:

[0072] 1) Reaction characteristics of extreme pressure agents and emulsifiers:

[0073] Reaction rate R, concentration of reaction product P, reaction time t.

[0074] 2) Working temperature characteristics:

[0075] Temperature T, temperature change rate ΔT / Δt.

[0076] 3) Pollutant characteristics:

[0077] Iron chip content F, content of other pollutants O.

[0078] Step 3: From the above characteristic data, the stability influence value of the extreme pressure agent and the emulsifier is obtained, and its formula is expressed as:

[0079] S 反应 = a1R + b1P + c1t + d1RP + e1Rt + f1Pt.

[0080] The stability influence value of the working temperature, its formula is expressed as:

[0081] S 温度 = g1T + h1ΔT / Δt + i1TΔT / Δt.

[0082] The stability influence value of the pollutant, its formula is expressed as:

[0083] S 污染 = j1F + k1O + l1FO + m1F 2 + n1O 2 .

[0084] Step 4: Considering the stability influences of the above three aspects, the overall stability calculation value of the emulsion is obtained:

[0085] Q = f × (S 反应 + S 温度 + S 污染 ).

[0086] Through a large number of experimental verifications and the parameter standards in the high-speed steel cutting process, the preset parameter values of a1, b1, c1, d1, e1, f1, g1, h1, i1, j1, k1, l1, m1, n1, and f in the above formula are obtained.

[0087] During the cutting process, the time t and the spatial position x are constantly changing. Therefore, a double integral is performed on the time t and the spatial position x in the calculation formulas of multiple stability influence values, and the following formula is obtained:

[0088] The stability influence value of the extreme pressure agent and the emulsifier, its formula is expressed as:

[0089]

[0090] The stability influence value of the working temperature, its formula is expressed as:

[0091]

[0092] The stability influence value of the pollutant, its formula is expressed as:

[0093]

[0094] Overall stability calculation value:

[0095] Q = f × (S反应 +S 温度 +S 污染 )。

[0096] In some embodiments, the stability calculation value Q within any time period (i.e., the overall stability calculation value in the above embodiments) is compared with the first preset value K (i.e., the preset stability threshold in the above embodiments). If the stability calculation value Q is greater than the first preset value K, it is determined that the stability of the emulsion is abnormal during this time period.

[0097] If the number of anomalies exceeds the preset value (i.e., the preset quantity threshold in the above embodiments), then the real-time data group corresponding to the stability calculation value with anomalies is traced to determine whether there are anomalies in the extreme pressure agent and emulsifier reaction data, working temperature data, or pollutant content data. If all real-time data is normal, then the extreme pressure agent and emulsifier reaction data, working temperature data, and pollutant content data are changed. The Q value is recalculated until it is less than the K value, indicating that a stable state has been reached.

[0098] If the new stability calculation value is still greater than K, the parameters are continuously adjusted until the stability calculation values within all time periods are less than K.

[0099] It should be noted that in this embodiment, experiments are carried out under three conditions: the reaction of the extreme pressure agent and emulsifier, working temperature, and pollutants. For the high-speed steel cutting process, the general stable preset threshold K is 35. The magnitudes of the Q value and the K value are judged by calculation.

[0100] To facilitate understanding of the above process, the present invention also provides the following embodiments:

[0101] Embodiment 1

[0102] In high-speed steel cutting, by real-time detecting the data of each point during work, transmitting it to a computer, and substituting the transmitted data into the following formula for calculation:;

[0103]

[0104] Furthermore, the comprehensive stability calculation value:

[0105] Q = f × (S 反应 +S 温度 +S 污染 )。

[0106] The following parameters are obtained through a large amount of previous data:

[0107] a1 = 0.2, b1 = 0.3, c1 = 0.1, d1 = 0.15, e1 = 0.1, f1 = 0.05, g1 = 0.4, h1 = 0.2,

[0108] i1 = 0.1, j1 = 0.3, k1 = 0.2, l1 = 0.1, m1 = 0.05, n1 = 0.05, f = 0.9.

[0109] Through the above formula calculation: Q = 34, which is less than K = 35. Then the emulsion has good stability.

[0110] Example 2

[0111] In high-speed steel cutting, by real-time detecting the data of each point during work, transmitting it to the computer, and substituting the transmitted data into the following formula for calculation:

[0112]

[0113] Comprehensive stability calculated value:

[0114] Q = f × (S 反应 + S 温度 + S 污染 ).

[0115] Through a large amount of previous data, the following parameters are obtained:

[0116] a1 = 0.2, b1 = 0.3, c1 = 0.1, d1 = 0.15, e1 = 0.1, f1 = 0.05, g1 = 0.4, h1 = 0.2,

[0117] i1 = 0.1, j1 = 0.3, k1 = 0.2, l1 = 0.1, m1 = 0.05, n1 = 0.05, f = 0.9.

[0118] Through the above formula calculation: Q = 36.2, which is greater than K = 35. Then there is a problem with the stability of the emulsion. Now, change the cutting fluid temperature, chip content and other conditions to optimize the stability parameter Q.

[0119] When extreme pressure agents and emulsifiers coexist in the emulsion, complex interactions may occur between them, and these interactions can affect the stability of the emulsion positively or negatively.

[0120] Temperature has a great influence on the stability of the cutting fluid. By changing the temperature, the stability of the cutting fluid is measured again, and at the same time, the chip content is also changed.

[0121] Again, substitute the collected data after the change into the following formula:

[0122]

[0123] The overall stability calculated value after recalculation, Q = 32.4 is less than the K value, and the cutting fluid reaches a stable state.
