汽车卧铺盖板拉延模设计毕业设计论文.doc

摘 要 本次设计做的是汽车车身覆盖件冲压模设计中的第一序拉延模的设计。汽车模具在中国因为发展的时间比较短所以在很多方面现在比起一些机械工业发达的国家还有很大的差距。但我国近年来在汽车模具方面也取得不少的发展与进步。本次设计我做的是汽车盖板的拉延模设计。在模具设计中主要是根据设计好的板件来用UG软件进行三维造型设计来完成模具的结构设计然后进行模具加工调试来最终生产出合格的模具。在三维造型方面主要可以分为压边圈设计、上模设计、凸模设计和下模本体设计。在进行各部分设计时要严格按照模具结构设计规范来进行设计。 在本次设计中我严格按照冲压模设计标准来进行模具设计，其中有一部分技术规范属于企业内部规范。本设计经过反复检查没有发现大的纰漏，完全符合模具设计的要求。 关键词：汽车模具 UG 拉延模 设计标准 Abstract The design do is auto body panel stamping die design sequence in the first drawing die design. Automotive die in China due to the development of a comparatively short time it is in many ways than some mechanical industrial developed countries there is a great gap. However, in recent years, China has also made the car a lot of mold development and progress. The design of the car I did the cover drawing die design. In the die design are mainly based on panels designed to use the UG software design to complete the three-dimensional structure of the mold and then mold design to final production of qualified commissioning of the mold. Main aspects of three-dimensional modeling can be divided into the blank holder design, the mold design, design and lower die punch body design. During the design of various parts of the structure to be in strict accordance with design specifications to the mold design. In this design I strictly in accordance with design standards for stamping die mold design, including technical specifications are part of the internal specification. After repeated checking of the design found no major flaws, in full compliance with the mold design.
