Based on the aluminizing process of automobile lamps, this paper studies the masking method of tooling in the non-aluminized area for the lamp parts with complex aluminized boundary structure. First, analyze the aluminized parts in the car lights, and determine four common aluminized boundary structure models; secondly, use a microscope to observe the aluminized transition area, and analyze the aluminized parts under different masking tooling parameters (H, J, Z) through a value and b value. And then, according to the analysis results, the design method of aluminized tooling with different aluminized boundary structures is given. Finally, the effectiveness of this conclusion is verified by practical cases.

In order to realize the image detection and identification of surface defects in the manufacturing and processing of metal parts, improve the image detection accuracy of unqualified products in the process of metal parts processing assembly line, improve the automation level of equipment in the process of metal defect detection, and solve the problems of easy fatigue, low detection effi-ciency, low detection accuracy, strong subjectivity and inability to adapt to the detection of large quantities of high-quality parts in manual detection. A convolution neural network model based on improved YOLOX-S is proposed for metal surface defect image detection. The model changed the structure of the unit module and introduced the attention mechanism module based on the original YOLOX-S model, which optimized the model parameters and improved bounding box position regression loss function and confidence loss function, and then the image detection model of common defects on the metal surface was constructed and realized. The results showed that the loss of improved YOLOX-S model could converge faster, the model with bounding box position regression loss function and attention mechanism added, its mAP increased from 94.23% to 96.14%, and the accuracy improvement effect is the best, while only a small amount of reasoning time is increased. Compared with the YOLOX-S model and the model with different improved methods, it is shown that the improved model based on bounding box position regression loss function and attention mechanism has the best comprehensive recognition effect, which can meet the require-ments of metal surface defect image detection and reduce the outflow of defective products in the production process of metal parts.

Air gap magnetic flux and magnetic flux leakage on the table are two important performance indi-* cators of the electrodynamic vibration generator. It’s required that the magnetic flux leakage should be as small as possible and air gap magnetic flux should be as large as possible. At present, the general method of increasing the air gap magnetic flux is to increase the ampere-turns of the excitation coil, but the magnetic flux leakage will increase synchronously. The magnetic flux leakage can be reduced by adding a degaussing coil, but it is inconvenient in the design, manufacture and use, and even generates larger stray magnetic fields in some locations. According to the use experience, appropriately reducing the ampere-turns ratio of upper and lower excitation coil can effectively reduce the magnetic flux leakage. Aiming at this phenomenon, it’s simulated that the influence of different upper and lower excitation ampere-turns ratio on air gap flux and magnetic flux leakage when the when the number of ampere-turns remains unchanged. In this paper, con-sidering the air gap magnetic field and the surface magnetic flux leakage, a new method of balanc-ing the air gap flux and the surface leakage is established.
