[0002] At present, in the automated forging production of hot die forging presses, in order to ensure the quality of forged products, the products forged by hot die forging presses are generally inspected. Most of them are manually scanned after the forgings are cooled and the data is entered into the system for further inspection.

Manual adjustment is still required, which seriously affects the efficiency of the equipment. Moreover, since some defects of forgings show similarities under certain conditions, some defects within the allowable range may be identified as quality defects, resulting in the existing technology being unable to accurately identify the defects of forgings and prone to misjudgment.

[0015] Step S4: When forging a new forging, the system detects the material quality and adjusts the mold of the equipment according to the result of the mold detection.

[0016] According to the above technical solution, step S2 further includes the following steps:

[0017] Step S21: Obtain infrared thermal data of the material, set the infrared thermal data collection cycle of the equipment, periodically obtain infrared data of the equipment in operation, identify the temperature of the equipment bearing, calculate the difference C between the equipment temperature in the current cycle and the equipment temperature collected in the most recent cycle, when the difference |C| is less than the threshold value set by the system, the system continues to detect the equipment temperature, when the difference |C| is greater than the threshold value set by the system, the abnormal temperature part of the equipment is marked, the working time of the equipment and the load rate under the working state are retrieved, if the load rate of the equipment is greater than the threshold value and the working time of the equipment is also greater than the threshold value, the current equipment is marked as an overloaded equipment, and the material input is reduced, otherwise the equipment is marked as a fault;

[0018] Step S22: retrieve comprehensive information data of the material to be processed, identify the code of the material to be processed, search the database according to the code of the material to be processed, obtain the hardness K of the material to be processed, search the processing history database according to the code of the material to be processed, and give the influence coefficient α of the hardness of the material to be processed on the tensile length of the material;

[0019] Step S23: Get the model of the mold, anchor the mold depression, measure the depth H of the most concave part of the mold, set the measurement interval, measure the width of the most concave part of the mold according to the set interval, calculate the width difference of the most concave part of the mold under adjacent intervals, if the width difference is less than the threshold set by the system, it means that the slope of the mold depression is steep, measure the inflection angle of the most concave part of the mold, call the corresponding stretching length influence coefficient η in the database according to the inflection angle, and calculate the length that the current material can be forged and stretched in the mold through the formula Where, L 1 Indicates the length of the material before processing, L 2 Indicates the length of the material after forging, λ indicates the influence coefficient of the pressure applied by the press on the forging length of the material, μ indicates the influence coefficient of the material's resilience on the stretching length, otherwise the current mold is marked as an available mold. If the length of the material after forging L 2 If the difference between the depth H of the most concave part of the mold and the depth H of the most concave part of the mold is less than the threshold, the current mold is marked as a usable mold, otherwise the current mold is marked as an unusable mold.

[0020] According to the above technical solution, step S3 further includes the following steps:

If the similarity between the image features is greater than the threshold set by the system, mark the current forging as a coarse-grained ring defective product; otherwise, the system continues to detect the remaining forgings and identify the marks in the forgings. If both edge defect marks and coarse-grained ring defect marks appear in the forging, the forging is marked as a coarse-grained ring defective product; otherwise, the defects of the forging are described according to the initial marks in the forging.

[0023] According to the above technical solution, the step S31 further includes the following steps:

[0024] Step S311: When the defect feature of the forging is a surface feature, the color value E of the pixel point on the surface of the forging part after grayscale processing is identified, and the color value difference Q between the pixel point and its upper, lower, left and right adjacent pixels is calculated in turn, and the color value of the pixel point is added to the color value difference, that is, the color value of the pixel point is G=E+Q, where G represents a new color value, and four new pictures are constructed using the new color value G respectively, and the four new pictures are overlapped and fused, and the feature nodes of the new pictures are scanned and identified, and the identified feature nodes are connected to construct a feature model, and the pixel point position of the feature model is anchored in the new picture, and the database image is searched according to the anchored pixel point position. If there is no corresponding feature point in the database image, the current forging part is marked as a scratch defective product, otherwise the system continues to detect;

[0025] Step S312: When a scratch defect mark is identified in the forged part, the color value of the pixel point of the visual image of the forged part is identified, the brightness of the visual image of the forged part is adjusted, the color value of the pixel point after the processing is scanned and identified, the difference between the color value of the pixel point before and after the processing is calculated, and the discrete coefficient of the difference of the color value of the pixel point is calculated by the formula Where i = 1, 2, 3...n, P represents the discrete coefficient of the pixel color value difference, M represents the difference between the pixel color values ​​before and after processing, It represents the average value of the difference between the color values ​​of the pixels before and after processing. If the discrete coefficient of the color value difference of the pixel is greater than the system threshold, it means that the surface of the current forging is oily and the current forging is marked as a qualified product. Otherwise, the current forging is marked as a scratch defective product.

[0026] According to the above technical solution, in step S4, infrared thermal data of the material is obtained, the temperature of the material is identified, and the temperature of the material is compared with a historical database. If the temperature of the material is less than a first threshold or greater than a second threshold, the material is marked as an unusable material, otherwise it is marked as an available material, and the mold detection results and material detection results are retrieved. The mold used by the equipment is adjusted according to the mold detection results, and the heating temperature and heating time of the equipment are adjusted according to the material detection results.
