Description

Technical Field

[0001] The present application belongs to the technical field of quenching equipment, and in particular to a method and device for detecting parameters of a quenching machine nozzle. Background Art

[0002] The quenching step in the heat treatment process is usually completed using a quenching machine. The nozzle is a key component of the quenching machine. Changes in its operating parameters will have a direct impact on the effect of the heat treatment process. Therefore, it is necessary to accurately control parameters such as the nozzle angle, water output, and water output pressure.

[0003] However, there are some reasons that may cause changes in the nozzle operating parameters. For example, the inevitable vibration during the operation of the quenching machine may cause the nozzle's spray angle to change. Another example is that the processed material accidentally hits the nozzle, causing it to become blocked or the spray angle to change.

[0004] Due to the complex internal environment of the quenching machine, there are some difficulties in detecting the nozzle operating parameters. The existing technology can often only judge the overall operation of the quenching machine through the processing results of the processed materials, and cannot accurately locate whether there is a problem with the nozzle, a precision mechanism.

[0005] Therefore, the industry urgently needs a method that can quickly and effectively detect nozzle operating parameters. Summary of the invention

[0006] The embodiments of the present application provide a method and device for detecting parameters of a quenching machine nozzle, which can solve the problem of difficulty in detecting nozzle operating parameters.

[0007] In a first aspect, an embodiment of the present application provides a method for detecting parameters of a quenching machine nozzle, comprising:

[0008] Acquire test data of the quenching machine nozzle; the test data refers to data of a structure formed by the spray water emitted from the nozzle impacting a viscous fluid disposed on a test mechanism;

[0009] Inputting the test data into a nozzle parameter detection model to obtain nozzle parameters as detection results; the nozzle parameters include a blockage degree parameter and a spray angle parameter of the nozzle;

[0010] The nozzle parameter detection model is a reversible mapping model between test data and nozzle parameters obtained based on empirical parameters.

[0011] The above method uses the structural data generated by the impact of the spray water ejected from the nozzle on the viscous fluid as the input of the nozzle parameter detection model, and obtains the nozzle parameters by matching calculation. It can use experience to obtain relatively accurate blockage degree parameters and injection angle parameters in one detection action, thus overcoming the problem of difficulty in detecting nozzle operation parameters in the prior art.

[0012] In a possible implementation manner of the first aspect, the nozzle parameters also include spray water pressure.

[0013] The above method makes fuller use of the test data to obtain the spray water pressure, thereby providing a more comprehensive data basis for adjusting the working conditions of the quenching machine.

[0014] In a possible implementation manner of the first aspect, the method further includes:

[0015] Acquire the pressure sensor data of the quenching machine nozzle; the pressure sensor data refers to the pressure data returned by the pressure sensor disposed on the test mechanism when the spray water emitted from the nozzle impacts the test mechanism;

[0016] The spray water pressure in the nozzle parameters is corrected according to the pressure sensor data.

[0017] The above method calibrates the pressure parameters of the nozzle through two different sources of data, namely, the pressure sensor data and the spray water pressure obtained by the nozzle parameter detection model, so as to obtain a more accurate spray water pressure value.

[0018] In a possible implementation of the first aspect, the step of obtaining quenching machine nozzle test data includes:

[0019] Controlling the nozzle to open within a preset uniformity detection period, and receiving data collected by a sensor of a structure formed by a spray water ejected by the nozzle within the uniformity detection period impacting a viscous fluid disposed on the test mechanism as test data;

[0020] The viscous fluid satisfies:

[0021] Under the action of gravity, the displacement of the viscous fluid during the uniformity detection period is less than a preset error tolerance range; and,

[0022] The thickness of the viscous fluid arranged on the testing mechanism is greater than the impact depth; the impact depth refers to the depth of the groove formed when the viscous fluid with infinite thickness is impacted by the spray water emitted from the unblocked nozzle during the uniformity detection period under ideal conditions.

[0023] The above method uses a viscous fluid with a thickness greater than the impact depth to ensure that the spray water cannot penetrate the viscous fluid layer during the uniformity detection period, so that the obtained test data can more comprehensively retain the spray intensity and / or spray water volume information at various locations within the spray range, providing more effective input data for the calculation of subsequent nozzle parameter detection models.

[0024] In a possible implementation manner of the first aspect, the blockage degree parameter includes a uniformity parameter; the uniformity parameter is used to determine the difference in emission intensity and / or the difference in emission water volume of the spray water emitted by the nozzle within a spray range.

[0025] The above method can make more full use of the test data by introducing uniformity parameters as model output, and provide a more comprehensive data basis for adjusting the working conditions of the quenching machine.

[0026] In a possible implementation manner of the first aspect, the step of inputting the test data into a nozzle parameter detection model to obtain the nozzle parameters as the detection result includes:

[0027] Inputting the data used for calculating the blockage degree parameter in the test data into the nozzle parameter detection model to obtain the blockage degree parameter;

[0028] If it is determined that the blocking degree parameter meets the preset blocking condition, the test is stopped and a maintenance prompt message is output.

[0029] The above method judges the blockage degree parameters. On the premise of determining that the nozzle is blocked, it can omit the test steps related to angle and pressure, stop the test and directly output maintenance prompts for relevant staff to promote maintenance work, thereby streamlining the parameter detection process and improving detection efficiency.

[0030] In a possible implementation manner of the first aspect, after the step of inputting the data in the test data used to calculate the blockage degree parameter into the nozzle parameter detection model to obtain the blockage degree parameter, the method further includes:

[0031] If it is determined that the blockage degree parameter does not meet the preset blockage condition, the data used to calculate the spray angle and the spray water pressure in the test data are input into the nozzle parameter detection model to obtain the spray angle and the spray water pressure;

[0032] If it is determined that the spray angle meets the preset angle abnormality condition, or if it is determined that the spray water pressure meets the preset pressure abnormality condition, then a maintenance prompt message is output;

[0033] If it is determined that the spray angle does not meet the preset angle abnormality condition, and the spray water pressure does not meet the preset pressure abnormality condition, then a test pass message is output.

[0034] The above method performs angle and pressure parameter detection on the premise that the nozzle is not blocked, and outputs test pass information or maintenance prompt information according to the detection results. It can automatically complete the detection process and provide sufficient nozzle operation parameters.

[0035] In a second aspect, an embodiment of the present application provides a quenching machine nozzle parameter detection device, comprising:

[0036] An acquisition module, used for acquiring test data of a quenching machine nozzle; the test data refers to data of a structure formed by spray water ejected from the nozzle impacting a viscous fluid disposed on a test mechanism;

[0037] A parameter module, used for inputting the test data into a nozzle parameter detection model to obtain nozzle parameters as detection results; the nozzle parameters include a blockage degree parameter and a spray angle parameter of the nozzle;

[0038] The nozzle parameter detection model is a reversible mapping model between test data and nozzle parameters obtained based on empirical parameters.

[0039] In a third aspect, an embodiment of the present application provides a terminal device, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the computer program, the method for detecting nozzle parameters of a quenching machine described in any one of the first aspects above is implemented.

[0041] In a fifth aspect, an embodiment of the present application provides a computer program product. When the computer program product is run on a terminal device, the terminal device executes the quenching machine nozzle parameter detection method described in any one of the first aspects above.

[0042] It can be understood that the beneficial effects of the second to fifth aspects mentioned above can be found in the relevant description of the first aspect mentioned above, and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] The present application embodiment provides a method for detecting parameters of a quenching machine nozzle, such as Figure 1 As shown, including:

[0061] Step 102, obtaining test data of the quenching machine nozzle; the test data refers to data of a structure formed by the spray water emitted from the nozzle impacting a viscous fluid disposed on a test mechanism;

[0062] Step 104, inputting the test data into a nozzle parameter detection model to obtain nozzle parameters as detection results; the nozzle parameters include a blockage degree parameter and a spray angle parameter of the nozzle;

[0063] The nozzle parameter detection model is a reversible mapping model between test data and nozzle parameters obtained based on empirical parameters.

[0064] In this embodiment, the construction of the nozzle parameter detection model can execute step 102 on the test mechanism with a debugged quenching machine (i.e., the nozzle is not blocked, the angle is correct, and the pressure is normal) to obtain test data corresponding to the nozzle parameters in the debugged quenching machine.

[0065] In an optional embodiment, the nozzle parameter detection model can be further optimized by the following method:

[0066] Adjust the spray water outlet pressure of the nozzle to the i-th pressure value, execute step 102, obtain the test data corresponding to the i-th pressure value and record it as the i-th pressure data; wherein i is a positive integer not greater than the preset pressure optimization times;

[0067] Performing fitting based on the i-th pressure value and the i-th pressure data to obtain a pressure sub-model in the nozzle parameter detection model;

[0068] Adjust the spray water emission intensity distribution of the nozzle to the jth distribution, execute step 102, obtain the test data corresponding to the jth distribution and record it as the jth blocking data; wherein j is a positive integer not greater than the preset blocking optimization times;

[0069] Perform fitting based on the j-th distribution and the j-th blockage data to obtain a blockage sub-model in the nozzle parameter detection model;

[0070] Adjust the spray water outlet angle of the nozzle to the kth angle, execute step 102, obtain the test data corresponding to the kth angle and record it as the kth angle data; wherein k is a positive integer not greater than the preset angle optimization times;

[0071] Perform fitting based on the k-th angle and the k-th angle data to obtain an angle sub-model in the nozzle parameter detection model;

[0072] Based on the pressure sub-model, the blockage sub-model and the angle sub-model, a fusion model is performed on the structure formed by the spray water ejected from the nozzle impacting the viscous fluid set on the test mechanism, and the fusion model is obtained as the nozzle parameter detection model called by the subsequent test process.

[0073] It is worth noting that, since the nozzles in the quenching machine may have different working angles, for example, the upper nozzle and the lower nozzle have working angles symmetrical along the horizontal plane, in a preferred embodiment:

[0074] The nozzle parameter detection model is based on the nozzle setting of a reference working angle (such as the working angle of the above nozzle); if the test data is test data for the nozzle at the reference working angle, the test data is directly input into the nozzle parameter detection model to execute step 104; if the test data is test data for the nozzle at a non-reference working angle, the test data is subjected to coordinate transformation and then input into the nozzle parameter detection model to execute step 104.

[0075] Furthermore, the test data may be constructed using a variety of schemes, for example:

[0076] 1. Use a viscous fluid with a higher viscosity (greater than a preset viscosity threshold) (to ensure that during the long period of taking out the test mechanism and measuring the data, the viscous fluid will not produce a displacement greater than the allowable error range due to gravity or the movement of the test mechanism), take out the test mechanism after the spray water impact and perform data measurement (such as visual measurement, rangefinder measurement, etc.).

[0077] 2. Using a visual sensor, in the process of the spray water emitted by the nozzle impacting the test mechanism, collect an image or a group of images (which should at least include the image after the spray water impact is completed);

[0078] 3. Using laser radar and / or millimeter wave radar, measure the structure after the spray water impacts the viscous fluid to obtain point cloud data.

[0079] The beneficial effects of this embodiment are:

[0080] The structural data generated by the impact of the spray water ejected from the nozzle on the viscous fluid is used as the input of the nozzle parameter detection model, and the nozzle parameters are obtained by matching calculation. Experience can be used to obtain relatively accurate blockage degree parameters and injection angle parameters in one detection action, overcoming the problem of difficulty in nozzle operation parameter detection in the prior art.

[0081] According to the above embodiment, in this embodiment:

[0082] The nozzle parameters also include spray water pressure.

[0083] Acquire the pressure sensor data of the quenching machine nozzle; the pressure sensor data refers to the pressure data returned by the pressure sensor disposed on the test mechanism when the spray water emitted from the nozzle impacts the test mechanism;

[0084] The spray water pressure in the nozzle parameters is corrected according to the pressure sensor data.

[0085] As an example and not limitation, the testing mechanism may be:

[0086] 1. A wooden testing mechanism, comprising a testing surface and a base, wherein butter is spread on the testing surface, and a pressure sensor is arranged on the testing surface or inside the testing surface;

[0087] 2. A metal testing mechanism, comprising a testing surface and a placement base, wherein butter is spread on the testing surface, and a pressure sensor is arranged on the testing surface or inside the testing surface.

[0088] The specific structure of the test surface and the placement base can refer to the box structure, that is, a rectangular hexahedron is used as the test structure, any panel of the hexahedron is used as the test surface, and the remaining part is used as the placement base.

[0089] In the wooden solution, the wooden material has better adhesion to butter or other viscous fluids, that is, the viscous fluid is less likely to slide on the wooden test surface.

[0090] In the metal solution, since metal materials have better force transmission effects (higher Young's modulus), it has a positive impact on the data accuracy of the pressure sensor.

[0091] In an optional embodiment, a plurality of the pressure sensors are arranged in a ring shape or in parallel on the test surface (or inside the test surface).

[0092] The beneficial effects of this embodiment are:

[0093] 1. Make fuller use of the test data to obtain the spray water pressure, providing a more comprehensive data basis for adjusting the working conditions of the quenching machine.

[0094] 2. The pressure parameters of the nozzle are calibrated by using the two different sources of data, namely, the pressure sensor data and the spray water pressure obtained by the nozzle parameter detection model, so as to obtain a more accurate spray water pressure value.

[0095] According to any of the above embodiments, in this embodiment:

[0096] The step of obtaining the quenching machine nozzle test data comprises:

[0097] Controlling the nozzle to open within a preset uniformity detection period, and receiving data collected by a sensor of a structure formed by a spray water ejected by the nozzle within the uniformity detection period impacting a viscous fluid disposed on the test mechanism as test data;

[0098] The viscous fluid satisfies:

[0099] Under the action of gravity, the displacement of the viscous fluid during the uniformity detection period is less than a preset error tolerance range; and,

[0100] The thickness of the viscous fluid arranged on the testing mechanism is greater than the impact depth; the impact depth refers to the depth of the groove formed when the viscous fluid with infinite thickness is impacted by the spray water emitted from the unblocked nozzle during the uniformity detection period under ideal conditions.

[0101] The blockage degree parameter includes a uniformity parameter; the uniformity parameter is used to determine the difference in the intensity of the spray water emitted by the nozzle within the spray range and / or the difference in the amount of the spray water emitted.

[0102] The above solution provided in this embodiment can more accurately retain the structural information formed by the spray water impacting the viscous fluid, so the obtained nozzle parameters are also more accurate, which is conducive to a clearer grasp of the nozzle state.

[0103] In practical applications, the following solution can also be used to make a qualitative judgment on whether the nozzle can continue to be used in a simpler and faster manner.

[0104] The thickness of the viscous fluid disposed on the testing mechanism is equal to the foundation depth;

[0105] The base depth refers to the depth of the groove formed when the viscous fluid with infinite thickness is impacted by the spray water emitted by the nozzle under the reference working condition during the uniformity detection period under ideal conditions;

[0106] The reference working condition refers to the working parameters of the nozzle that just meet the minimum requirements of the quenching process;

[0107] The test data is image test data of the test surface of the test mechanism after the spray water impact is completed;

[0108] The step of inputting the test data into the nozzle parameter detection model to obtain the nozzle parameters as the detection result comprises:

[0109] The spray angle of the nozzle is determined according to the spray range of the spray water in the image test data. If the spray angle is abnormal, a maintenance prompt message is output; otherwise:

[0110] Determining that in the image test data, the viscous fluid does not exist within the spraying range of the spray water, and outputting test pass information;

[0111] Determining that the viscous fluid exists within the spraying range of the spray water in the image test data, and outputting maintenance prompt information;

[0112] The principle of this simple solution is that, for a viscous fluid with a thickness equal to the foundation depth, the spray water emitted by a nozzle that meets the requirements can at least wash away the viscous fluid within the spray range; conversely, if there is residual viscous fluid somewhere within the spray range, then it can be determined that the spray water intensity or water volume at that location is insufficient and cannot meet the use requirements.

[0113] It is worth noting that the "water" mentioned in the embodiments of the present application should be understood as a quenching liquid, and its actual chemical composition may not be H2O, but a certain preset aqueous solution or other liquid.

[0114] The beneficial effects of this embodiment are:

[0115] By using a viscous fluid with a thickness greater than the impact depth, it is ensured that the spray water cannot penetrate the viscous fluid layer during the uniformity detection period, so that the obtained test data can more comprehensively retain the spray intensity and / or spray water volume information at various locations within the spray range, providing more effective input data for the calculation of subsequent nozzle parameter detection models.

[0116] By introducing uniformity parameters as model output, the test data can be more fully utilized, providing a more comprehensive data basis for adjusting the working conditions of the quenching machine.

[0117] According to any of the above embodiments, in this embodiment:

[0118] The step of inputting the test data into the nozzle parameter detection model to obtain the nozzle parameters as the detection result comprises:

[0119] Inputting the data used for calculating the blockage degree parameter in the test data into the nozzle parameter detection model to obtain the blockage degree parameter;

[0120] If it is determined that the blocking degree parameter meets the preset blocking condition, the test is stopped and a maintenance prompt message is output.

[0121] After the step of inputting the data in the test data used to calculate the blockage degree parameter into the nozzle parameter detection model to obtain the blockage degree parameter, the method further includes:

[0122] If it is determined that the blockage degree parameter does not meet the preset blockage condition, the data used to calculate the spray angle and the spray water pressure in the test data are input into the nozzle parameter detection model to obtain the spray angle and the spray water pressure;

[0123] If it is determined that the spray angle meets the preset angle abnormality condition, or if it is determined that the spray water pressure meets the preset pressure abnormality condition, then a maintenance prompt message is output;

[0124] If it is determined that the spray angle does not meet the preset angle abnormality condition, and the spray water pressure does not meet the preset pressure abnormality condition, then a test pass message is output.

[0125] This embodiment provides a logical sequence for the operation of the nozzle parameter detection model. Under this logical sequence, the efficiency of nozzle parameter detection can be maximized.

[0126] The beneficial effects of this embodiment are:

[0127] By judging the blockage degree parameters, it is possible to omit the test steps related to angle and pressure, stop the test and directly output maintenance prompts for relevant staff to advance maintenance work, simplify the parameter detection process and improve detection efficiency, under the premise of determining that the nozzle is blocked.

[0128] On the premise of confirming that the nozzle is not blocked, the angle and pressure parameters are tested, and the test pass information or maintenance prompt information is output according to the test results. The detection process can be completed automatically and sufficient nozzle operation parameters can be provided.

[0129] According to any of the above embodiments, a relatively complete embodiment will be given below based on an exemplary application scenario of steel plate quenching.

[0130] First, the background of the application scenario of this embodiment is briefly introduced.

[0131] In order to improve the comprehensive performance of steel plates, steel mills generally quench the steel plates, and quenching must be done with a quenching machine. Steel mills often use roller quenching machines for quenching steel plates.

[0132] The roller quenching machine consists of a frame, two rows of rollers, water pipes and nozzles, traditional devices, etc. The most precise part is the angle of the water pipe and the nozzle on the spray beam. The water volume, pressure, and uniformity of spraying onto the steel plate must be ensured so that the microstructure obtained by quenching the steel plate meets the standards.

[0133] In actual use, the quenching machine often changes the nozzle's spray angle (and other parameters) due to the impact of steel plate deformation on the nozzle and equipment vibration. Once these main parameters change, it will affect the quenching effect and the quality of the steel plate tempering process.

[0134] At present, there are few manufacturers that can design and produce quenching machines and nozzles at home and abroad. When there is a production failure or the quenching machine is overhauled, the replacement or cleaning of the nozzles involved requires adjusting the angle of the nozzle on the spray beam, the actual water pressure and the amount of water. The design and production manufacturers are basically confidential about these parameters, there are no specific parameters and no drawings. In the above situation, it is necessary to find the technicians of the quenching machine manufacturer to reinstall the nozzles and water pipes on site, which will cause unnecessary production stoppages and losses on the one hand, and there is also the problem of high costs on the other hand.

[0135] Therefore, the purpose of this embodiment is to more accurately measure the main parameters such as the angle of the nozzle on the spray beam, whether the nozzle is blocked, and the pressure.

[0136] Taking the common roller quenching machine as an example, this embodiment adopts a two-stage measurement scheme (i.e., the pressure test is independent of the nozzle angle / blockage test)

[0137] 1) Measure the angle of the nozzle on the spray beam and whether the nozzle is blocked:

[0138] Make a wooden box with a length equal to the width of the quenching machine (900mm in height and 200mm in width). Mark the angle in the vertical direction on the widest vertical surface of the box (900mm*quenching machine length), and evenly apply relatively dry butter on this surface (the thickness must not be less than 2mm).

[0139] 2)Measure pressure:

[0140] Make a box in the same way as 1), made of steel plate, and install a pressure detector inside, which can accurately detect the force (pressure) of water hitting the steel plate.

[0141] When the quenching machine is overhauled or a production accident is handled, if you want to measure the main parameters of the quenching machine, follow the steps.

[0142] 1. Measure the angle of the nozzle on the spray beam.

[0143] Step 1: Raise the upper rollers of the quenching machine to the maximum height (1000mm) and place the wooden box vertically at the designated position of the nozzle to be measured.

[0144] Step 2: Open the corresponding nozzle, and the water sprayed from the nozzle will wash away the butter on the board surface.

[0145] Step 3: Turn off the sprinkler water and take out the box.

[0146] Step 4: From the buttered side (or both sides), you can find the angle of the nozzle on the spray beam.

[0147] 2. Measure the uniformity of water sprayed from the nozzle on the spray beam (in the corresponding angle direction).

[0148] Step 1: Raise the upper rollers of the quenching machine to the maximum height (1000mm) and place the wooden box flat on the designated position of the nozzle to be measured.

[0149] Step 2: Open the corresponding nozzle and then close it immediately. The water sprayed from the nozzle will flush the butter on the board into different shapes.

[0150] Step 3: Turn off the sprinkler water and take out the box.

[0151] Step 4: From the buttered side, you can tell whether the nozzle on the spray beam is clogged.

[0152] 3. Measure the pressure of water sprayed from the nozzle on the spray beam

[0153] Step 1: Raise the upper rollers of the quenching machine to the maximum height (1000mm) and place the box with the pressure detector at the designated position where the nozzle pressure is to be measured.

[0154] Step 2: Open the corresponding nozzle, and the water sprayed from the nozzle will hit the pressure tester box.

[0155] Step 3: After the pressure is uniform, it can be concluded that the pressure is the actual pressure of the water sprayed out of the nozzle.

[0156] illustrate:

[0157] 1. The measurement methods for the main parameters of upper and lower nozzles and nozzles in different areas are the same.

[0158] 2. When measuring the angles of the lower and upper nozzles, the boxes are in opposite directions.

[0159] 3. The location of the box and the timing of switching on and off the water spraying should be well controlled.

[0160] 4. Generally, for a newly debugged quenching machine, these parameters can be measured first as a backup.

[0161] 5. When measuring water pressure, you can connect a pressure display or a built-in pressure recorder to record the process curve of pressure changes.

[0162] Corresponding to the quenching machine nozzle parameter detection method described in the above embodiment, Figure 2 A structural block diagram of a quenching machine nozzle parameter detection device provided in an embodiment of the present application is shown. For ease of explanation, only the parts related to the embodiment of the present application are shown.
