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 TOC \o 1-3 \h \z \u 21598 1 引言 1 27211 2 冲压制品设计概论 1 13431 2.1 模具的概念及其在工业生产中的作用 1 29261 2.2 冲压加工工艺及其应用 1 25391 2.3 冲压所用材料及其性能 2 21258 2.4 冲模的组成 2 14051 2.5 冲模的工作部分零件必须具备的性能 3 16457 2.6 冲模的成形特点 4 22451 3 冲压技术的发展 4 16213 3.1 冲压成形工艺与理论研究 4 25788 3.2 冲压技术的数字化与信息化 5 28110 4 汽车覆
