Description

Technical Field

[0001] The present application relates to the technical field of steel plate shearing, and in particular to a steel plate shearing tracking method and system. Background Art

[0002] Thinner steel plates have good hardness and are easy to process. They are widely used in the shell processing of many equipment. When processing different steel plate sizes, corresponding shearing treatment is required.

[0003] In the related art, the steel plate to be processed is rolled up on a feed roller, which rotates as needed to transport the steel plate toward the shearing device. Before the steel plate reaches the shearing device, it needs to be flattened and sheared accordingly. Since the steel plate has certain stress and is easily affected by temperature, the shearing part of the steel plate is prone to breakage due to its brittleness during rapid movement and shearing, resulting in small-distance dimensional positioning errors in the steel plate.

[0004] Regarding the above-mentioned related technologies, when dimensional positioning errors occur during the steel plate shearing process, it is easy to affect the steel plate shearing accuracy, which needs to be improved. Summary of the Invention

[0012] Step 5: Instruct the preset length calculation wheel to monitor the transmission distance of the steel plate, and shear the steel plate when the transmission distance is equal to the preset reference shear distance.

[0013] By adopting the above technical solution, the temperature of the steel plate is cooled and adjusted accordingly before shearing, so that the shearing position of the steel plate is not easily affected by temperature and thus stress defects are generated. This helps to reduce the probability of affecting the shearing accuracy during the shearing process and improve the shearing quality of the steel plate.

[0032] By adopting the above technical solution, when adjusting the cooling temperature, the thickness and heat conduction efficiency of the steel are analyzed and calculated to generate a corresponding feedback adjustment signal to drive the cooling device to adjust the cooling temperature, so that the cooling effect on the steel surface is not affected by the thickness of the steel, the cooling uniformity of the steel on the shear section is improved, and the shearing effect of the steel plate is better.

[0048] By adopting the above technical solution, when adjusting the temperature of the steel plate, the cooling length and the minimum cooling area that can be effectively cooled are analyzed, so that the cooling device can reduce the cooling energy consumption when cooling the steel plate.

[0049] Optionally, the surface cooling of the steel plate also includes:

[0050] Calculate the cooling time based on the cooling length and the preset cooling rate;

[0051] Matching the time gain value in the preset time gain database based on the cooling time;

[0053] Instruct the preset cooling device to increase the cooling gas flow rate and airflow rate, and to cool the cooling sub-areas synchronously according to the minimum spacing distance.

[0054] By adopting the above technical solution, the time gain value required for cooling the cooling length is analyzed and compared. When the gain value generated by cooling is a negative gain, the corresponding cooling rate and cooling area are adjusted, so that the cooling device can improve the cooling efficiency.

[0074] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-7 It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0075] The embodiments of the present invention are described in further detail below with reference to the accompanying drawings.

[0076] An embodiment of the present application discloses a steel plate shear tracking method, which performs corresponding cooling temperature adjustment before shearing the steel plate to increase the brittleness of the steel plate at the shearing position where it is sheared according to size, and reduces the stress impact caused by the temperature increase, so that the shearing of the steel plate is less likely to cause problems such as cracking and bending jitter, thereby helping to improve the shearing positioning accuracy.

[0077] Reference Figure 1 The method flow of the steel plate shear tracking method includes the following steps:

[0078] Step 1 S100: When the conveying roller conveys the steel plate to the preset plate head shearing device for shearing positioning, the plate head shearing position of the steel plate is collected;

[0079] When shearing steel plates, a flying shear system is used for shearing, wherein the flying shear system includes a conveyor roller for coiling the steel to be sheared, and a plate head shear for the first shearing of the steel to determine the initial end face position of the steel, and the sheared end face is defined as the plate head shearing position.

[0080] Step 2 S200: Analyzing the shearing position of the plate head and the preset shearing steel plate size to determine the shearing position of the steel plate;

[0081] The steel plate shearing position indicates the location of multiple shear planes on a continuous steel plate as it is continuously transported and sheared to specifications. This is determined by monitoring the steel plate's transport speed and marking the corresponding shearing position when the transport distance reaches the set distance. The steel plate shearing size is the target length dimension set according to requirements.

[0082] Step 3 S300: collecting the steel plate transmission speed and the steel plate temperature, and analyzing them using a preset temperature analysis strategy to determine the cooling temperature corresponding to the steel plate transmission speed and the steel plate temperature;

[0083] The transmission speed of the steel plate is acquired through a speed sensor. The temperature analysis strategy represents the method and steps for calculating the cooling temperature of the steel plate at the detected transmission speed. The specific calculation method will be further described in subsequent steps.

[0084] Preset temperature analysis strategies include:

[0085] Calculate the cooling temperature based on the steel plate transmission speed and steel plate temperature;

[0086] The cooling temperature is calculated using the following formula:

[0087] ;

[0088] in, Indicates the cooling temperature value, It indicates the proportional coefficient of the linear increase of cooling temperature when the steel plate transmission speed increases. Indicates the collected steel plate transmission speed, Indicates the linear proportional coefficient of cooling temperature when the steel plate temperature increases, Indicates the temperature of the steel plate during transmission, A constant representing the effect of the environment on cooling.

[0089] Step 4 S400: When the shearing position of the steel plate is in the preset cooling area, instruct the preset cooling device to adjust the temperature of the steel plate according to the cooling temperature;

[0090] The cooling device is a rapid gas cooling nozzle connected to the PLC control system. It receives control signals from the PLC control system and cools the steel plate, resulting in a brittleness and stress level suitable for shearing. The cooling zone is the area where the cooling device can move and cool. When the plate shearing position is within the preset cooling zone, the cooling device adjusts the cooling temperature of the steel plate.

[0091] Step five S500: instructing the preset length calculation wheel to monitor the transmission distance of the steel plate, and shearing the steel plate when the transmission distance is equal to the preset reference shearing distance.

[0092] The sizing wheel is a positioning mechanism used in a flying shear system to determine the distance a steel plate is transported. The transport distance represents the total distance a steel plate travels as it is continuously transported from the conveyor roller, based on the shearing position of the plate head. The reference shearing distance represents the dimensional distance of the steel plate.

[0093] Reference Figure 2 Before calculating the cooling temperature, the temperature of the steel plate during transportation must be confirmed:

[0094] Step S301: Analyze the cooling area and the preset shearing area to determine the moving interval distance of the steel plate after cooling;

[0095] The purpose of analyzing the moving interval distance is to understand the temperature change of the steel plate after cooling the shear position and before transferring to the shear area, which helps to correct the timing of the subsequent cooling temperature calculation.

[0096] Step S302: Calculating based on the moving interval distance and the steel plate transmission speed to determine the transmission time required for the steel plate after temperature adjustment and before shearing;

[0097] The transmission time is calculated by dividing the moving distance by the steel plate transmission speed. The purpose of calculating the transmission time is to be called for further analysis of the temperature change of the steel plate.

[0098] Step S303: matching the temperature influence ratio corresponding to the transmission time in the preset temperature change database, and calculating the effective cooling temperature of the steel during shearing;

[0099] The temperature change database stores different temperature influence ratios and transmission times that are mapped to the temperature influence ratios. When the transmission time is output, the corresponding temperature influence ratio can be matched and output, that is, the temperature change ratio within the transmission time can be known. The temperature change rate ratio is multiplied by the cooling temperature, and the resulting value is defined as the effective cooling temperature, that is, the temperature of the steel plate when it reaches the shearing area.

[0100] Step S304: replacing the effective cooling temperature with the temperature of the steel plate during transportation.

[0101] The effective cooling temperature is replaced by a temperature close to the actual steel plate temperature so that it can be provided as a calculation variable before calculating the cooling temperature required by the cooling device, so that the cooling temperature is more in line with actual needs.

[0102] Reference Figure 3 , when the cooling device adjusts the temperature of the steel plate according to the cooling temperature, it includes:

[0103] Step S401: collecting and analyzing a temperature thermal image of a region at a shearing position of a steel plate to determine a surface temperature of the shearing region at the shearing position;

[0104] The temperature thermal imaging diagram can be obtained by configuring the corresponding industrial thermal imaging detector on the flying shear system and performing corresponding detection. The collected shear area thermal imaging diagram is analyzed to know the surface temperature of the shear area where the steel is in the shear area.

[0105] Step S402: matching the thermal conductivity efficiency in a preset thermal conductivity efficiency database based on the preset steel thickness and steel type;

[0106] Different steel thicknesses and types have different heat transfer efficiencies. A thermal conductivity efficiency database is pre-established to store different steel thicknesses and steel types in the database and match them with corresponding thermal conductivity efficiencies. When the steel thickness and steel type are input, the corresponding thermal conductivity efficiency can be searched and output.

[0107] Step S403: Calculating based on the heat conduction efficiency and the surface temperature of the shearing area to determine the adjusted temperature value of the steel on the shearing section;

[0108] The value calculated by multiplying the surface temperature of the shear area and the heat conduction efficiency is defined as the temperature adjustment value, which represents the average temperature transferred in the thickness direction of the shear section.

[0109] Step S404: generating a feedback adjustment signal based on the temperature adjustment value and a preset standard adjustment range;

[0110] By comparing and analyzing the temperature adjustment value and the value of the standard adjustment range, when it exceeds the standard adjustment range, the temperature adjustment value is gradually lowered, and when it is lower than the standard adjustment range, the temperature adjustment value is gradually increased. Both are to adjust the amount of cooling temperature, and different adjustments generate corresponding feedback adjustment signals.

[0111] Step S405: performing cooling temperature feedback adjustment on the next steel plate shearing position of the sheared steel plate based on the feedback adjustment signal.

[0112] After receiving the feedback adjustment signal, the cooling temperature of the next shearing position of the continuously transmitted steel plate is adjusted so that the subsequent steel plates can obtain better quality and shearing accuracy when shearing.

[0113] Reference Figure 4 , when performing cooling temperature feedback adjustment, it also includes:

[0114] Step S4051: collecting and analyzing the shear surface position of the steel material after shearing to determine the shear length of the sheared steel material;

[0115] The collection of shear length is for further analysis of whether the shearing of the steel plate after temperature adjustment has good accuracy. The shear length can be obtained by measuring the sheared steel using a laser rangefinder.

[0116] Step S4052: performing a difference analysis based on the shearing length and a preset standard shearing length to determine the shearing length difference;

[0117] The standard shear length indicates the standard distance in the length direction of the steel plate specification. By calculating the difference between the shear length and the standard shear length, the difference between the sheared steel plate and the standard length steel plate can be obtained.

[0118] Step S4053: matching the influence weight ratio corresponding to the shear length difference in the preset temperature influence weight database;

[0119] The influence weight ratio represents the correction value of the temperature adjustment on the shear length difference. The temperature influence weight database stores the influence weight ratios corresponding to different shear length differences. By looking up the corresponding influence weight ratios, the corrected cooling adjustment temperature can be further calculated.

[0120] Step S4054: performing calculation based on the influence weight ratio and the cooling temperature to determine the cooling adjustment temperature, and instructing the preset cooling device to adjust according to the cooling adjustment temperature.

[0121] By multiplying the influence weight ratio and the cooling temperature, the corrected cooling adjustment temperature can be obtained, and corresponding adjustments can be made to improve the cooling adjustment effect and reduce the shear length difference.

[0122] Reference Figure 5 , when adjusting the temperature of the steel plate according to the cooling temperature, it also includes:

[0123] Step S406: collecting a shear surface image of the shear position of the steel plate to perform a shear surface flatness analysis to determine the shear surface flatness;

[0124] The interface of the shearing position is imaged by a pre-arranged camera and defined as a shearing surface image. The shearing surface image is subjected to a flatness image feature analysis to determine the shearing surface flatness for subsequent use.

[0125] Step S407: comparing the shear surface flatness with a preset standard flatness, and matching the priority shear speed corresponding to the cooling adjustment temperature in the preset shear speed database;

[0126] Standard flatness indicates the flatness of the sheared surface that meets the requirements. Priority shear speed indicates the upper limit of shear speed that can be performed without affecting the sheared surface flatness at the cooling adjustment temperature. By establishing a shear speed database, different cooling adjustment temperatures are stored in the database and matched with corresponding priority shear speeds. When the cooling adjustment temperature is input, the corresponding priority shear speed can be output.

[0127] Step S408: adjusting the shearing speed of the preset shearing device based on the priority shearing speed indication.

[0128] The shearing speed of the shearing device is adjusted so that the shearing device can improve the efficiency of steel plate shearing.

[0129] Reference Figure 6 , when the cooling device adjusts the temperature of the steel plate according to the cooling temperature, it includes:

[0130] Step S409: Analyze based on the size of the sheared steel plate to determine the cooling length of the sheared position of the steel plate on the sheared section;

[0131] The cooling length indicates the width distance in the shear direction of the steel plate size. This distance is positioned as the cooling length for subsequent call-up.

[0132] Step S410: matching the corresponding minimum cooling area in the preset cooling database based on the cooling length, and generating a cooling path according to the cooling length and the steel plate shearing position;

[0133] When cooling according to the cooling length, different lengths require a certain surface area for cooling so that the cooling can be conducted to the steel plate in a shorter time. The required minimum cooling range area is defined as the minimum cooling area. A cooling database is established in advance to store different cooling lengths and match them with corresponding minimum cooling areas. When the cooling length is entered, the minimum cooling area is automatically matched and output.

[0134] A cooling path can be formed by extending along the cooling length direction according to the shear position of the steel plate, so as to facilitate cooling adjustment according to the cooling path and adjust the spraying angle of the cooling nozzle to maintain the cooling spray with the minimum cooling area.

[0135] Step S411: instructing a preset cooling device to perform surface cooling on the steel plate according to the cooling path and the minimum cooling area.

[0136] Surface cooling is performed according to the minimum cooling area and cooling path, so that the steel plate can quickly and effectively adjust its temperature, maintain good shear brittleness and stress adjustment, and improve the flatness of the cut surface.

[0137] Reference Figure 7 , when the steel plate is surface cooled, it also includes:

[0138] Step S412: performing calculation based on the cooling length and the preset cooling rate to determine the cooling time;

[0139] Cooling time indicates the time required to complete temperature adjustment of the minimum cooling area under the premise of constant cooling rate. The purpose of calculating cooling time is to further analyze the gains and negative gains caused by time consumption.

[0140] Step S413: matching the time gain value in the preset time gain database based on the cooling time;

[0141] The time gain value indicates the gain in work efficiency due to shearing time under the premise of maintaining good shearing. The longer the cooling time is, the worse the gain effect is.

[0142] Step S414: when the time consumption gain value is less than the preset negative gain value, generating multiple cooling sub-areas according to the cooling length and the minimum spacing distance;

[0143] Negative gain values ​​mean that cooling takes longer, resulting in lower gains in shearing efficiency. Negative gain values ​​are set by personnel based on their needs. Cooling sub-regions represent multiple adjacent sub-regions on the cooling path. When cooling these sub-regions, based on the heat transfer efficiency of the steel, the cooling of the steel plate can be more evenly adjusted, while reducing the area requiring cooling, thereby reducing cooling time.

[0144] Step S415: instructing the preset cooling device to increase the cooling gas flow rate and airflow rate, and to synchronously cool the cooling sub-areas according to the minimum spacing distance.

[0145] The cooling gas flow and airflow rate are both increased according to the set unit value, and cooling adjustments are performed on multiple cooling sub-areas at the same time, which can maintain the cooling effect and time consumption.
