[0058] Refer to Figure 1 As shown, it is a schematic flowchart of a method for preparing a communication mold based on semi-solid magnesium alloy provided by an embodiment of the present invention. Among them, Figure 1 The method for preparing a communication mold based on semi-solid magnesium alloy described in
[0059] S1. Obtain the preparation materials for the communication mold, analyze the component ratio of the preparation materials, and obtain the target materials when the component ratio meets the preset ratio. Among them, the preparation materials refer to semi-solid magnesium alloy materials.
[0060] Through the step of obtaining the preparation materials for the communication mold in the embodiments of the present invention, the basic materials for preparing the mold can be obtained. Among them, the preparation materials refer to semi-solid magnesium alloy materials.
[0061] Further, in the embodiment of the present invention, by analyzing the component ratio of the preparation material, it can be understood whether the preparation material meets the preset ratio, and the component ratio can be obtained through actual detection.
[0062] Further, after analyzing the component ratio of the preparation material, the embodiment of the present invention further includes: querying the measured ratio of each element in the preparation material, and based on the measured ratio, calculating the variance test statistic of the magnesium alloy component in the preparation material by combining the following formula:
[0063]
[0064] Wherein, β represents the variance test statistic of the magnesium alloy component, A represents element A in the semi-solid material of the magnesium alloy, A% represents the ideal ratio of element A, a% represents the measured ratio of element A, B represents element B in the semi-solid material of the magnesium alloy, B% represents the ideal ratio of element B, b% represents the measured ratio of element B, C represents element C in the semi-solid material of the magnesium alloy, C% represents the ideal ratio of element C, c% represents the measured ratio of element C, N represents element N in the semi-solid material of the magnesium alloy, N% represents the ideal ratio of element N, and n% represents the measured ratio of element N.
[0065] Wherein, the test statistic refers to a hypothesis testing method for statistical analysis, usually used to compare whether the variances of two or more groups of data are equal, or to test the significance of certain parameters in the statistical model, etc. When the component ratio meets the preset ratio, obtaining the target material means that the value of β meets the preset ratio, and the preset ratio is usually determined according to specific material requirements, process standards and experience. It is a judgment boundary used to determine whether the component ratio is within an acceptable range.
[0066] S2. Use a pre-configured furnace to dissolve the target material to obtain a liquid material, analyze the liquid phase distribution state of the liquid material, and when the liquid phase distribution state meets the preset state, obtain the first processing material.
[0067] In the embodiment of the present invention, by using a pre-configured furnace to dissolve the target material to obtain a liquid material, it can make the elements in the target material mix more fully, so that the components are more uniform, ensuring consistent performance of the mold in different parts.
[0068] As an embodiment of the present invention, the utilization of a pre-configured furnace to dissolve the target material to obtain a liquid material includes: after injecting a pre-configured inert gas into the pre-configured furnace, starting the pre-configured furnace to dissolve the target material, and during the material dissolution process, controlling the temperature of the pre-configured furnace within a preset range. When the target material becomes liquid, a liquid material is obtained.
[0069] Among them, the pre-configured furnace can be a resistance furnace or a gas furnace. The inert gas refers to argon. During the material dissolution process, controlling the temperature of the pre-configured furnace within a preset range means controlling the change in the temperature of the configured furnace within an interval, such as within ±5°C. The temperature can be detected in real time by a precision temperature sensor, and the heating power of the pre-configured furnace can be adjusted in real time through a temperature control device for feedback.
[0070] Furthermore, in the embodiment of the present invention, by analyzing the liquid phase distribution state of the liquid material, the mass uniformity of the liquid material, whether there is local composition segregation or temperature difference can be evaluated.
[0071] As an embodiment of the present invention, the analysis of the liquid phase distribution state of the liquid material includes:
[0072] Collect the surface image of the liquid material, perform image enhancement processing on the surface image to obtain an enhanced image, extract the image texture and image shape of the enhanced image, calculate the average diameter of the particles in the liquid phase of the liquid material, and analyze the liquid phase distribution state of the liquid material based on the image texture, the image shape, and the average diameter.
[0073] Optionally, the surface image can be collected by a thermal imaging device. Performing image enhancement processing on the surface image to obtain an enhanced image means enhancing the image details, which can be obtained by filtering the surface image through a filter and then sharpening the surface image. The average diameter of the particles in the liquid phase of the liquid material can be measured by a particle size analyzer.
[0074] As an alternative embodiment of the present invention, the analysis of the liquid phase distribution state of the liquid material based on the image texture, the image shape, and the average diameter includes: calculating the distribution density and uniformity of the particles in the liquid material based on the image texture and the image shape, and calculating the distribution difference value of the liquid material based on the distribution density, the uniformity, and the average diameter using the following formula:
[0075]
[0076] Among them, S represents the distribution difference value, D1 Denote the average diameter as D 0 Denote the ideal average diameter corresponding to the average diameter as ρ 1 Denote the distribution density as ρ 0 Denote the ideal distribution density corresponding to the distribution density as K 1 Denote the uniformity as K 0 Denote the ideal uniformity corresponding to the uniformity;
[0077] Based on the distribution difference, determine the liquid-phase distribution state of the liquid material.
[0078] The process of calculating the distribution density and uniformity of the particles in the liquid material based on the image texture and the image shape is as follows: use the image texture and the image shape to identify the texture features and shape features of the particles in the liquid phase, and based on the texture features and the shape features, use machine learning or other data analysis methods to analyze and model the extracted features to calculate the distribution density and uniformity of the particles.
[0079] It should be noted that when the liquid-phase distribution state meets the preset state, obtaining the first processed material means that the calculation result of the distribution difference is not greater than the preset value, and obtaining the material that meets the requirements of subsequent operations,
[0080] The preset value can be set to 0.1, or can be set according to the actual application scenario.
[0081] S3. Use a pre-configured stirring device to stir the first processed material to obtain a stirred material, analyze the solid-phase particle distribution state of the stirred material, and when the solid-phase particle distribution state meets the preset state, obtain a second processed material.
[0082] In the embodiment of the present invention, by using the pre-configured stirring device to stir the first processed material to obtain a stirred material, the shear force generated by the stirring can be used to break the growing grains in the material and inhibit the grain growth, so as to obtain a finer grain structure and improve the strength and toughness of the mold. Among them, the pre-configured stirring device can be a mechanical stirring device.
[0083] As an embodiment of the present invention, using the pre-configured stirring device to stir the first processed material to obtain a stirred material includes: obtaining the stirring process of the material stirring, using the stirring process to set the stirring speed and stirring time of the pre-configured stirring device, and based on the stirring speed and the stirring time, using the pre-configured stirring device to stir the first processed material to obtain a stirred material. Among them, the stirring process refers to the parameters of the stirring device during stirring, such as the stirring speed is 100-200 revolutions per minute and the stirring time is 10-20 minutes, which can be adjusted according to the specific application scenario.
[0084] Furthermore, in the embodiment of the present invention, the stirring effect of the stirred material can be understood by analyzing the solid-phase particle distribution state of the stirred material.
[0085] As an embodiment of the present invention, analyzing the solid-phase particle distribution state of the stirred material includes: obtaining a microscopic image of the stirred material, identifying the solid-phase particles in the microscopic image, labeling the solid-phase particles to obtain labeled particles, identifying the particle positions, particle sizes, and particle shapes of the labeled particles, and determining the solid-phase particle distribution state of the stirred material based on the particle positions, the particle sizes, and the particle shapes.
[0086] Among them, the microscopic image of the stirred material can be obtained by a scanning electron microscope. The solid-phase particles in the microscopic image can be identified by a deep learning model by identifying the image features of the microscopic image and based on the image features. The process of labeling the solid-phase particles to obtain labeled particles can be performed by a U-Net network. The process of determining the solid-phase particle distribution state of the stirred material based on the particle positions, the particle sizes, and the particle shapes is as follows: using the particle positions to determine whether the solid-phase particles are evenly distributed in the liquid phase of the stirred material, and determining whether the solid-phase particles are fine and smooth based on the particle sizes and the particle shapes.
[0087] It should be noted that when the solid-phase particle distribution state meets the preset state, obtaining the second processed material means that the distribution state of the solid-phase particles is that fine, uniform, and nearly spherical solid-phase particles are evenly distributed in the liquid phase, and the spacing between the solid-phase particles is relatively consistent. If the solid-phase particle distribution state does not meet the preset state, the stirring parameters of the pre-configured stirring device are adjusted until the solid-phase particle distribution state meets the preset state.
[0088] S4. Cool the second processed material using a pre-configured cooling device, and complete the cooling when the second processed material presents a semi-solid state to obtain a third processed material. Use a pre-configured die-casting device to perform die-casting on the third processed material to obtain an initial mold. Perform a toughness test on the initial mold. When the test result of the toughness test is excellent, obtain a target mold, and perform rough machining on the target mold to obtain a first processed mold.
[0089] In the embodiment of the present invention, by using the pre-configured cooling device to cool the second processed material and completing the cooling when the second processed material presents a semi-solid state to obtain a third processed material, a solid material can be obtained, which is convenient for the processing of communication molds.
[0090] As an embodiment of the present invention, cooling the second processed material by using a pre-configured cooling device and completing the cooling when the second processed material presents a semi-solid state to obtain a third processed material, including: designing a cooling channel and arranging a water channel for the pre-configured cooling device to obtain a target cooling device, setting parameters for the cooling medium corresponding to the target cooling device to obtain a set cooling medium, using the target cooling device and the set cooling medium to cool the second processed material, and completing the cooling when the second processed material presents a semi-solid state to obtain a third processed material. Wherein, the pre-configured cooling device is a water-cooled cooling device. Wherein, the semi-solid state refers to an intermediate state where the material is neither completely liquid nor completely solid.
[0091] Optionally, for the designing of the cooling channel and arranging the water channel for the pre-configured cooling device to obtain a target cooling device, the density of the cooling water channels can be increased at the key parts of the mold, or conformal cooling water channels can be used. For setting parameters for the cooling medium corresponding to the target cooling device to obtain a set cooling medium, the temperature, flow rate and pressure of the cooling medium such as water, oil or air can be set, and the cooling rate of the cooling device can be controlled within
[0092] 5 - 10 °C / second, which is specifically set according to the actual application scenario. For completing the cooling when the second processed material presents a semi-solid state to obtain a third processed material, it is determined by analyzing the solid phase ratio (the volume fraction occupied by the solid phase) of the second processed material, and the solid phase ratio is usually between 20% and 80%.
[0093] Furthermore, in the embodiment of the present invention, by using a pre-configured die-casting device to perform die-casting on the third processed material to obtain an initial mold, the semi-solid magnesium alloy slurry can be quickly filled into the mold cavity of the die-casting machine under high pressure, realizing high-precision forming of a mold blank with a complex shape, ensuring the accuracy of dimensions and shapes, and meeting the design requirements of communication molds.
[0094] Optionally, the process of using a pre-configured die-casting device to perform die-casting on the third processed material to obtain an initial mold is as follows: inputting the third processed material into the barrel of the pre-configured die-casting device, setting the die-casting pressure within the range of 50 - 100 MPa, and setting the die-casting speed to 3 - 5 m / s to obtain a preliminarily formed mold blank, and in the microstructure morphology of the mold blank, the solid phase particles should maintain good morphology and distribution.
[0095] Further, in the embodiment of the present invention, by performing a toughness test on the initial mold, it can be determined whether the mold meets the expected toughness standard, and its ability to withstand impact, vibration, and alternating loads during use can be judged, thereby evaluating the quality and reliability of the mold.
[0096] It should be noted that when the test result of the toughness test is excellent, obtaining the target mold means that no cracks and obvious deformations occur in the target mold during the test.
[0097] In the embodiment of the present invention, by performing rough machining on the target mold to obtain the first processed mold, an initial mold with relatively excellent quality can be obtained. Among them, the rough machining refers to the preliminary carving of the mold.
[0098] Optionally, performing rough machining on the target mold to obtain the first processed mold can be achieved by performing hot processing on the target mold to obtain a hot processed mold, and then performing cutting processing on the hot processed mold according to the preset mold shape and size by using a numerical control machine tool.
[0099] S5. Perform defect detection on the first processed mold. When there are defects in the first processed mold, repair the defects of the first processed mold to obtain a repaired mold, and then perform fine machining on the repaired mold to obtain the target communication mold.
[0100] In the embodiment of the present invention, by performing defect detection on the first processed mold, it can be understood whether there are defects inside the first processed mold, such as cracks, unevenness, etc., to avoid producing defective products in subsequent production.
[0101] As an embodiment of the present invention, performing defect detection on the first processed mold includes: collecting a finished product image of the first processed mold, performing image edge detection on the finished product image, based on the result of the image edge detection, performing image segmentation on the finished product image to obtain a segmented image, identifying the image features of the segmented image, and based on the image features, performing defect detection on the first processed mold to obtain a defect detection result.
[0102] Optionally, performing image edge detection on the finished product image refers to the process of identifying and locating the boundaries of objects in digital image processing, which is achieved through Canny edge detection. Performing image segmentation on the finished product image based on the result of the image edge detection to obtain a segmented image is achieved through a target segmentation algorithm. Identifying the image features of the segmented image is achieved through a convolutional neural network algorithm. Performing defect detection on the first processed mold based on the image features to obtain a defect detection result is achieved through image matching analysis of a large number of finished product images related to the first processed mold collected by a deep learning model.
[0103] Furthermore, in the embodiment of the present invention, when there are defects in the first processing mold, the defects of the first processing mold are repaired to obtain a repaired mold, which can make up for the defects in the mold processing to ensure the quality of the finished mold during the production process. The defects of the first processing mold can be repaired by welding or filling methods.
[0104] Furthermore, in the embodiment of the present invention, the repaired mold is finely processed to obtain a target communication mold, which can improve the service life and performance of the mold. Among them, the fine processing refers to using a high-precision numerical control machine tool to process with a cutting depth of 0.1-0.2 mm until the required accuracy and surface roughness requirements of the communication mold are achieved, and the surface of the finely processed mold is treated, and a wear-resistant and corrosion-resistant coating such as nickel or chromium is plated on the mold surface by electroless plating or electroplating methods.
[0105] As an embodiment of the present invention, after the repaired mold is finely processed to obtain a target communication mold, it further includes: calculating the production comprehensive score of the target communication mold by using the following formula:
[0106]
[0107] And, W 1 +W 2 +W 3 +W 4 +W 5 =1
[0108] Among them, ZP represents the production comprehensive score, M represents the average deviation of the elemental composition, L represents the total deviation of the characteristics of the liquid material particles from the ideal value, G represents the total deviation of the characteristics of the solid-phase particles from the ideal value, C represents the deviation of the cooling and die-casting parameters from the ideal value, F represents the deviation of the defect and repair effect from the ideal value, and W 1 represents the weight of M, W 2 represents the weight of L, W 3 represents the weight of G, W 4 represents the weight of C, W 5 represents the weight of F.
[0109] It should be noted that according to the production comprehensive score, the comprehensive and overall evaluation level of the target communication mold can be understood, and the situation of only focusing on a single link and ignoring other factors that may have an important impact on the mold quality can be avoided.
[0110] As Figure 2 shown, it is a functional module diagram of a communication mold preparation system based on magnesium alloy semi-solid state of the present invention.
