油封盖冲压工艺分析与模具设计摘要用模具技术生产的制品具有高精度、高复杂程度、高一致性、高生产效率和低消耗等特点。由此可见，模具技术已成为衡量一个国家产品制造水平高低的重要标志，决定着产品的质量、效益和新产品的开发能力。 本论文详细的论述了冲压模具的全过程。冲压模具即是在冲压加工中，将材料（金属或非金属）加工成零件（或半成品）的一种特别工艺装备。 该零件是离合器壳体，该产品的模具采纳了由送料机自动给料的加工方法、成本低、生产效率高。该产品的精度要求一般，结构简单。关键是怎样实现机器自动给料，从而省去人工给料的过程。本文还主要论述了冲裁零件的结构工艺分析、凹凸模刃口尺寸的设计计算、冲裁排样与定位元件的设计、冲压力与压力中心的计算和模具的主要零件的结构设计等。 改进后的模具可实现自动化，大大降低了成本，提高了生产效率。关键词： 落料、冲孔、模具间隙AbstractDie technology to produce products with high accuracy, high complexity, high consistency, high production efficiency and low consumption and so on. Thus, die technology has become the measure of a country manufacturing an important indicator of the level determines the product quality, efficiency and new product development capability. This paper discusses in detail the whole process of stamping dies. Stamping die that is in the process of stamping, the material (metal or non-metallic) processing into parts(orsemi-finished products) of a special technical equipment. The parts are baffle, the product of mold using an automatic feeding from the feeder processing methods, low cost and high efficiency. The general accuracy of the product, simple structure. The key is how to achieve an automatic feeding machine, thus eliminating the need for manual feeding process.This article also discusses the major processes of structural stampings, embossing Edge Design Calculation, blanking layout and positioning components, design, red center of pressure and stress calculation and...
