Description

Technical Field

[0001] The present application relates to the field of bar production, and in particular to a bar tolerance measurement method and device based on flying shear length measurement. Background Art

[0002] Bars are important materials widely used in the manufacturing industry, and their dimensional accuracy has a direct impact on the quality and performance of the final product. With the continuous advancement of industrial technology and the increasingly fierce market competition, enterprises have become more and more stringent in their requirements for the dimensional tolerance control of bar products. The dimensional tolerance of bars not only affects the performance of the product, but is also closely related to production costs and material utilization. Therefore, improving the precision control level of bar production will not only help improve the market competitiveness of products, but also reduce material loss and increase the economic benefits of enterprises.

[0003] In the small bar production workshop, products are usually delivered according to theoretical weight, which means that negative rolling needs to be strictly controlled during the production process, that is, to minimize material waste while ensuring product quality. Through precise tolerance control, the production process and material use can be optimized while maintaining product quality, thereby achieving higher profits.

[0004] Traditional tolerance online measurement technology mainly relies on the weight data of the steel billet. It measures the length of the bar after rolling and converts it into the theoretical weight under the standard meter weight, and then compares it with the weighing data at the entrance of the rolling mill to calculate the tolerance value. However, since the material weight tracking process is often unstable and the weighing process itself has errors, the above errors may come from factors such as insufficient equipment accuracy, inaccurate data collection, and environmental changes, this method has significant limitations.

[0005] At present, the online tolerance measurement method of the bar and wire production line usually adopts a standard measurement model, that is, by measuring the length of the bar at the exit of the rolling line, converting it into a theoretical weight, and then comparing it with the actual weighing data at the entrance to obtain the tolerance value. In order to reduce the influence of errors, a correction factor is usually introduced to correct the measurement results in order to improve the measurement accuracy. However, the existing technology uses the weight of the billet to calculate the tolerance of the bar. Due to the instability of the billet weight tracking and the error of the billet weighing itself, the tolerance measurement results will have large errors and large fluctuations. Summary of the invention

[0006] In response to the problems in the prior art, the present application provides a bar tolerance measurement method and device based on flying shear length measurement, which can design a bar tolerance measurement model based on flying shear length measurement data with higher data accuracy and stronger data stability, and calculate the bar tolerance in real time, thereby effectively improving the bar tolerance measurement accuracy.

[0043] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] The acquisition, storage, use, and processing of data in the technical solution of this application comply with the relevant provisions of national laws and regulations.

[0045] Taking into account that the existing technology uses the weight of the steel billet to calculate the bar tolerance, due to the instability of the steel billet weight tracking and the error of the steel billet weighing itself, etc., the tolerance measurement results will have large errors and large fluctuations. The present application provides a bar tolerance measurement method and device based on flying shear length measurement. A bar tolerance measurement model is designed based on flying shear length measurement data with higher data accuracy and stronger data stability to calculate the bar tolerance in real time, thereby effectively improving the bar tolerance measurement accuracy.

[0046] In order to design a bar tolerance measurement model based on flying shear length measurement data with higher data accuracy and stronger data stability to calculate the bar tolerance in real time, and effectively improve the bar tolerance measurement accuracy, the present application provides an embodiment of a bar tolerance measurement method based on flying shear length measurement, see Figure 1 The bar tolerance measurement method based on flying shear length measurement specifically includes the following contents:

[0047] Step S101: Determine the current weight ratio parameter based on historical data within a preset time period, wherein the historical data includes a multiple shear length measurement data sequence, a flying shear length measurement data sequence, a corresponding finished bundle weighing data sequence, and a finished bundle theoretical weight, and the current weight ratio parameter is used to characterize the linear relationship between the flying shear length measurement and the bar tolerance.

[0048] First, the current weight ratio parameter is determined by analyzing the historical data within a preset time period. The historical data includes the length measurement data series of the double shears, the length measurement data series of the flying shears, the actual weighing data series of the finished bales, and the theoretical weight of the finished bales. The above data reflects the measurement information of the production process in different time periods, and can provide a comprehensive perspective to understand the relationship between the length measurement of the flying shears and the weight of the finished bales.

[0049] The weight ratio parameter is a key indicator used to characterize the linear relationship between the flying shear length measurement and the bar tolerance. By calculating this parameter, the changing trend of the flying shear length measurement data and the bar tolerance can be accurately reflected, helping to establish a measurement model that can adapt to the current production status.

[0050] The above process ensures that the model can reflect the actual measurement conditions in the production process, thereby improving the accuracy and stability of the measurement results.

[0051] Step S102: updating the pre-established linear model of flying shear length measurement and bar tolerance according to the current weight ratio parameter to obtain an updated linear model.

[0052] After determining the current weight ratio parameters, the present application utilizes a self-learning mechanism to update the pre-established linear models of flying shear length measurement and bar tolerance.

[0053] The self-learning mechanism refers to a mechanism in which the system continuously adjusts and optimizes itself through its own experience and data to adapt to environmental changes or improve performance. The weight ratio parameter is theoretically a fixed value, but due to various errors in production that cannot be quantified and changes in production conditions, the weight ratio parameter is actually a dynamically changing value. Therefore, it is necessary to continuously solve the weight ratio parameter value according to changes in actual production conditions so that the model has a certain self-learning ability.

[0054] By updating the current model with the current weight ratio parameters, it can be better adapted to the current production conditions, ensuring that the model can respond to any changes in the production process in a timely manner and improving measurement accuracy.

[0055] Step S103: input the current flying shear length measurement data and the current multiple-length shear length measurement data into the updated linear model to obtain the current bar tolerance measurement value.

[0056] After the model update is completed, the current flying shear length measurement data and the multiple shear length measurement data are input into the updated linear model to calculate the current bar tolerance measurement value. This measurement value directly reflects the dimensional accuracy of the bar under the current production status and can be used to monitor and adjust the production process to ensure the consistency of product quality.

[0057] Through real-time calculation and feedback mechanisms, the production management system can quickly identify and correct any deviations that may affect product quality, maintaining optimal production efficiency and quality, which not only improves measurement accuracy but also ensures the stability and efficiency of the production process.

[0058] From the above description, it can be seen that the bar tolerance measurement method based on flying shear length measurement provided in the embodiment of the present application can design a bar tolerance measurement model based on flying shear length measurement data with higher data accuracy and stronger data stability to calculate the bar tolerance in real time, thereby effectively improving the bar tolerance measurement accuracy.

[0059] In one embodiment of the bar tolerance measurement method based on flying shear length measurement of the present application, see Figure 2 The construction process of the linear model of flying shear length measurement and bar tolerance includes:

[0060] Step S01: acquiring multiple flying shear length measurement data, multiple-length shear length measurement data, finished product bundle actual weight data and finished product bundle theoretical weight data of the bar production equipment in the historical production process, and determining the flying shear corresponding to the flying shear length measurement data that can transmit the length measurement data to the multiple-length shear as the target flying shear;

[0061] Step S02: determining the ratio of the theoretical weight per meter and the length measurement data of the bar at the target flying shear to the theoretical weight per meter of the bar at the multiple-length shear as a weight ratio parameter;

[0062] Step S03: determining the bar tolerance according to the actual weight data of the finished product bundle and the theoretical weight data of the finished product bundle;

[0063] Step S04: Determine the linear relationship between the length measurement data ratio of the target flying shear and the multiple-length shear, the weight ratio parameter and the bar tolerance as a linear model of the flying shear length measurement and bar tolerance.

[0064] In an optional embodiment of the present application, the products of the small rod workshop are delivered according to the theoretical weight, that is, under the premise of qualified products, the uneven size of the rods is ignored, and the weighing tolerance of the finished bundle is used as the tolerance of the rods. The tolerance calculation formula is as follows:

[0065]

[0066] Among them, m s : The actual weight of the finished bundle, unit: kilogram (kg); ml : Theoretical weight of the finished bundle, unit: kilogram (kg); θ 成品 : Weighing tolerance of finished bales.

[0067] In the production of bars, the changes in the elongation ratio can be observed to observe the changes in the working conditions. For a high bar production line with 5 flying shears, it was observed that the changes in the length measurement of the 1# flying shear and the 2# flying shear will not be transmitted to the length measurement L5 of the double shear, while the elongation ratio between the length measurement L5 of the double shear and the length measurement L3 of the 3# flying shear can better reflect the changes in the working conditions. Therefore, the length measurement L5 of the double shear and the length measurement L3 of the 3# flying shear (i.e. the target flying shear) are selected to design the tolerance measurement model.

[0068] Ignoring the error in the production process after the flying shear length measurement, the following equation relationship is established:

[0069]

[0070] Among them, L5: measured length of multiple-length shear, unit: meter (m); L3: measured length of 3# flying shear, unit: meter (m); m3: theoretical meter weight of bar at 3# flying shear, unit: kg / m; m5: theoretical meter weight of bar at multiple-length shear, unit: kg / m.

[0071] Ideally, As a fixed value, recorded as weight ratio parameter k, the linear model of flying shear length measurement and bar tolerance is as follows:

[0072]

[0073] because With θ 成品 It is a linear relationship, so we can observe changes and understand the changes in bar tolerances.

[0074] In an optional embodiment, the flying shear length measurement data sequence represents a data sequence of the flying shear corresponding to the flying shear length measurement data that can transmit the length measurement data to the multiple-length shears.

[0075] In another optional embodiment, the pre-established linear model of flying shear length measurement and bar tolerance is updated according to the current weight ratio parameter to obtain an updated linear model, including:

[0076] The weight ratio parameters in the pre-established linear model of flying shear length measurement and bar tolerance are replaced by the current weight ratio parameters to obtain an updated linear model.

[0077] Specifically, the pre-established linear model of flying shear length measurement and bar tolerance is updated according to the current weight ratio parameter. In the process of obtaining the updated linear model, the change of k value can be ignored in a short period of time due to the small change of production conditions, because the recent k value can be continuously obtained to participate in the calculation of future bar tolerance. The calculation formula for finding k at the current time t is as follows:

[0078]

[0079] Among them, t represents the time of data, t∈[1,n]; k t represents the parameter k at time t; It represents the multiple shear length at time t; Indicates the measured length of the 3# flying shear at time t; Indicates the weighing tolerance of the finished bundle corresponding to time t.

[0080] In order to enhance the stability of the model k value, a period of historical data is selected to calculate the k value at time t:

[0081]

[0082] Among them, n-1 represents the length of the selected historical data, n is a positive integer and n>1.

[0083] Therefore, summarizing the above formula, we can get the bar tolerance θ based on the flying shear length measurement at time t. t The measurement model is as follows:

[0084]

[0085] Afterwards, when the current flying shear length measurement data and the current multiple-length shear length measurement data are input into the updated linear model, the parameter k value at time t is calculated based on the historical data for a period of time. The historical data includes the multiple-length shear length measurement data series 3# Flying shear length measurement data sequence Corresponding finished bundle weighing data sequence and finished bundle theoretical weight m l .

[0086] In order to further illustrate the present solution, the present application also provides a specific application example of using the above-mentioned bar tolerance measuring device based on flying shear length measurement to implement a bar tolerance measuring method based on flying shear length measurement.

[0087] The present application uses field data over a period of time to calculate the weight ratio parameter k of the model, and uses the parameter-updated model to measure the bar tolerance online.

[0088] Table 1 shows some of the flying shear length measurement data involved in the calculation.

[0091] Table 2 shows some of the finished product bale data involved in the calculation.

[0093]

[0094]

[0095] The calculated measurement tolerance and the corresponding finished bundle tolerance comparison curve are as follows: Figure 3 As shown, compared with the weighing tolerance curve of the finished bundle, the real-time measurement tolerance curve is smoother and has better data stability. The real-time measurement curve and the envelope under the weighing tolerance curve of the finished bundle are basically coincident, indicating that the measurement tolerance has good accuracy. It can be shown that the real-time measurement method and system for bar tolerance based on flying shear length measurement proposed in the present invention can measure the bar tolerance in a timely and accurate manner after the flying shear length measurement is completed.

[0096] In order to design a bar tolerance measurement model based on flying shear length measurement data with higher data accuracy and stronger data stability to calculate the bar tolerance in real time, and effectively improve the bar tolerance measurement accuracy, the present application provides an embodiment of a bar tolerance measurement device based on flying shear length measurement for realizing all or part of the bar tolerance measurement method based on flying shear length measurement, see Figure 4 The bar tolerance measuring device based on flying shear length measurement specifically includes the following contents:

[0097] The measurement parameter acquisition module 1101 is used to determine the current weight ratio parameter according to the historical data in a preset time period, wherein the historical data includes a multiple shear length measurement data sequence, a flying shear length measurement data sequence, a corresponding finished product bundle weighing data sequence and a finished product bundle theoretical weight, and the current weight ratio parameter is used to characterize the linear relationship between the flying shear length measurement and the bar tolerance;

[0099] The tolerance measurement module 1103 is used to input the current flying shear length measurement data and the current multiple-length shear length measurement data into the updated linear model to obtain the current bar tolerance measurement value.
