1、 - I - 阀门叶片轴架落料及成形模具设计阀门叶片轴架落料及成形模具设计 摘要摘要 随着全球经济一体化的深入，模具工业在国民经济中所发挥的作用越 来越明显。模具设计水 平的高低直接影响产品的质量及生产效率。 冲裁是最基本的冲压工序。本设计重点是在分析冲裁变形过程及冲裁 件质量影响因素的基础上，介绍冲裁工艺计算、工艺方案制定和冲裁模设 计。涉及冲裁变形过程分析、冲裁件质量及影响因素、间隙确定、刃口尺 寸计算原则和方法、排样设计、冲裁力与压力中心计算、冲裁工艺性分析 与工艺方案制定、冲裁典型结构、零部件设计及模具标准应用、冲裁模设 计方法与步骤等。 由于模具设计是一种经验性较强的设计，经过长期发

2、展积累了大量丰 富的冲压工艺技术资料，在设计模具时必然要借鉴这些经验数据，含括了 弯曲模、成形模中常用的工艺数，据以及模具材料的选取和压力机基本参 数等等。 本次设计不仅让我熟悉了课本所学的知识，而且让我做到把所学的知 识运用到实践当中，更让我了解了模具设计的全过程和加工实践的各种要 点。使我在书本和实践当中有一个质的飞跃。 关键词关键词： 单工序模单工序模 冷冲压冷冲压 板料板料 弯曲成形弯曲成形 - II - The valve blade shaft frame blanking and forming die design Abstract With the deepening of

3、global economic integration, more and functions of die and mould industry has played in the national economy more obvious. The mold design level will directly affect the product quality and production efficiency. Blanking is the most basic of stamping process. This design focus is on the analysis of

As the mold design is a strong empirical de

6、sign, after a long-term development has accumulated a large variety of stamping technology, in the design of die when bound to learn from these experiences, including the bending die, forming process and die a few die, according to the selection of materials and basic parameters. This design not only let me know the textbook knowledge, and let me do the learned knowledge into practice, let me understand the various points of the whole process of mold design and processing practice. I have
