汽车闪光器外壳落料拉深模具的设计及仿真
摘要 汽车用闪光器有电热式闪光器、弹跳式闪光器、电容式闪光器、晶
体管式闪光器、集成电路式闪光器, 现在经常用的有晶体管闪光器和集成电路闪光器两大类，近年来闪光器又有了新的发展动向, 从过去的单一继电器控制发展成双继电器控制电路, 即闪光器在左右转向时分别由2只继电器控制, 双闪报警时2个继电器同时工作, 这种专用集成电路的出现,增加了闪光器电路的复杂性。引出端子已经从过去3个端子增加至8个端子或更多。
本次的设计的主要内容是闪光灯落料拉深模具的设计及仿真，模具的设计很好的巩固和加强大学期间所学的专业知识，扎实专业基础知识和提高专业技能，仿真可以让我认识一些新的领域，本次设计出不仅要设计出符合质量要求的模具，而且也要达到制件的质量要求。在本次设计之前，就开始对汽车闪光器方面的知识进行了学习，进入设计阶段的第一步是对制件进行工艺性分析以保证各工序动作行程的稳妥和连贯，然后对模具设计的工艺方案进行看分析并确定，接下来的重要一步便是对于主要工艺参数的计算。此后完成排样、模具结构设计等任务，最后画出设计零件图和总装图，并对三维图形进行动态仿真。
通过仿真的结果分析，证明了模具设计的合理性也是可行的。在仿真中对虚拟模具的性能进行了模拟测试，达到了了设计的要求和性能，通过反复的改正和试验也使模具的设计成本得到了降低，是整个设计得到优化，生产得到了初步的肯定。

Auto flash drawing blanking shell mold design and simulation
Abstract
Car has electric heating device with flash flash, pop-flash, capacitor flashlight, transistor flasher, IC-type flash, there is now often used in transistors and integrated circuits flasher flasher two categories, in recent years Flasher has a new development trend from the past development of a single dual relay control relay control circuit, that is, turn left and right flasher respectively by the two relay control, double flash when the alarm 2 relay simultaneously This emergence of ASIC, an increase of the complexity of the flash circuit. Lead terminal has increased over the past three terminals to 8 terminals or more.
The design of the main contents of the flash off the deep drawing die design and simulation, mold design and simulation of a good university to consolidate and strengthen the expertise of the school, a solid foundation of professional knowledge and improve professional skills, and secondly to designed to meet the quality requirements of the mold, in order to achieve the quality requirements of parts. In this design prior to the start of the automobile flasher knowledge to the learning, the design stage is the first step in the process of analysis of parts of the process to ensure the safe operation and consistent schedule, and then the mold design process program to analyze and determine the look, the next important step is the calculation for the main process parameters. After completion of layout, die design and other tasks, and finally draw the design of part drawings and assembly diagrams, and dynamic simulation of three-dimensional graphics.
The results of the simulation proved the rationality of die design is feasible. Die in the simulation performance of the virtual simulated tests reached the design requirements and performance tests through repeated corrections and also make mold design costs have been reduced to optimize the entire design, production and get a preliminary positive .
Keywords: Auto flasher; blanking drawing; mold design; Simulation
