Research on Aluminized Boundary of Car Lamp Parts

摘要: 本文基于汽车车灯镀铝工艺，主要针对复杂镀铝边界结构的车灯零件，进行了非镀铝区域工装遮蔽方式的研究。首先对车灯中的镀铝零件进行分析，确定了常见的四种镀铝边界结构模型；其次利用显微镜观察镀铝过渡区域，通过a、b值分析不同遮蔽工装参数(H, J, Z)下镀铝边界的状态，并根据分析结果给出不同镀铝边界结构的镀铝工装设计方法；最后，通过实际案例验证了本文结论的有效性。

Abstract: 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.
