Infiltration and cross-integration of stamping the field of computer technology, information technology, modern measurement and control technology, to promote the formation and development of advanced stamping technology. The characteristics of the development of the entire industrial production product varieties more updates soon, competitive market. To adapt to the the mold manufacturing short delivery time, high-precision, low-cost urgent requirement. Mold design experience in the design phase to the theoretical calculation and the development of computer-aided design direction, the technology is widely used in the modeling industry, the mold structure more scientific and rational, greatly improve the precision mold processing, shorten the cycle of mold design and processing, reduced product development time. This paper focuses on the development status and prospects of stamping technology detail. Key words: stamping technology; mold design; development status and prospects.. 目 录 1 引言 1 2 冲压技术的发展 1 2.1 冲压成形工艺与理论研究 1 2.2 冲压技术的数字化与信息化 1 3 汽车覆盖件的冲压成形及其发展 2 3.1 国内外研究现状 2 3.2 覆盖件成形工艺及其发展趋势 3 4 汽车覆盖件冲压工艺设计发展方向 3 4.1 多种方法的混合智能新技术 3 4.2 工艺设计关键部分的各个突破和集成设计 4 4.3 数值模拟技术的成形模拟应用 4 5 覆盖件成形过程中的常见质量问题及解决办法 4 5.1 起皱 4 5.2 破裂 5 5.3 回弹 6 6 成形工艺参数 7 6.1 压边力 7 6.2 拉延筋成形阻力 7 6.3 凸模或凹模成形力及成形速度 7 6.4 润滑条件 8 7 结束语 9 参考文献 10 致谢 11 侯文龙： 你论文的题目是冲压技术的应用与发展，你应该介绍什么是冲压，冲压的种类有哪些，冲压的应用领域是哪！你可以以汽车为例来说明冲压技术的应用，但冲压技术不仅是用在汽车上！你还应该介绍冲压技术的发展现状和发展趋势！ 你要把论文从前到后仔细的看一遍，不要有错别
