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 view of the preload problem of the preload of the ultra-high pressure mold by the prestressed wire winding device, a new type of wire tension adjustment mechanism is designed to change the tension of the steel wire to adjust the prestress size of the mold. The mechanical model analysis of the generation of steel wire tension is carried out, and the axial stress change of steel wire under different pressures, different speeds and different diameters is analyzed by finite element soft-ware. The results show that the axial stress of the steel wire has a nonlinear relationship with the speed of the steel wire, and with the increase of the speed of the steel wire, the axial stress of the steel wire first increases, reaches the peak, and then decreases and eventually tends to be stable; The axial stress of the steel wire is proportional to the hydraulic cylinder pressure and inversely proportional to the diameter of the wire.

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.
