校徽内形冲压模具设计 摘要 模具技术水平的高低是衡量一个国家制造业水平的重要标志之一，模具是高新技术产业的重要组成部分，是工业生产的基础装备。模具技术是一门综合性很强精密基础工艺装配技术，涉及新技术，新工艺，新材料，新设备的开发与推广应用；是冶金，材料，计量，机电一体化等多门学科以及铸造，锻造，热处理，机加工，检测等多工种共同打造的系统工程。用模具生产制品具有高效率，高一致性，高精度，高复杂性，低消耗等特点。模具制造业以成为与高新技术产业为依托的产业。 我国模具正保持年均的比例增长，随着改革开放所带来的经济发张，我国模具总产值仅次于日本，美国之后。在深圳周边及珠三角地区聚集了6000多家模具企业，从业人员超过20万人。已连续在深圳举办了五届的华南国际模具展，吸引了25个国家和地区的1000多家企业参加，是当今中国最具专业化、国际化水准的模具工业展会。广东也即将成为世界五金工具模具中心。越来越多发达国家的模具正向我国转移，从而加剧了该专业人口的缺乏。随着人们生活水平的提高，人们对汽车领域，电子领域，医疗领域，办公领域，航空领域的依附性加大，而这些行业对模具的依附性确相当的大如:汽车的更新换代，航空的钣金成型，电子产品的塑料成型等。与发达国建相比我国模具的创新性不够，一些先进技术依旧没有掌握，模具的标准化还在完善之中，一些先进的设备依旧需要进口，而这些先进的技术设备大部分集中在国有企业，生产条件还依旧落后，一些小企业依旧沿用着手工操作+机械化；对大,高精密模具依旧需要进口，而自主设计的模具从使用寿命，使用性能上依旧落后余发达国家；然而在模具材料以及加工所用的大部分刀具，依旧需要进口。 展望未来，随着时代进步，新时代人们对模具更高的要求，加工上追求：高速度，高精度，高质量；使用上追求：高性能；当然面对这些新时代所提出的新口号，传统的加工方式难以满足模具人员的需求；随着模具的智能化，以及现在流行的一些加工方式，一些专家预测模具的加工技术将会将会朝着下列一些技术发展：1.全面推进技术；2.高速铣削加工技术；3.模具扫描及数字技术化；4.电火花铣削加工技术；5.提高模具标准化程度；6.优质材料表面处理技术；7.模具研磨抛光自动化，智能化技术；8.模具自动加工技术；9.打印技术。将来的模具无论从使用寿命，加工性能上远远优越现在的模具。当然对将来的模具人员的要求的整体要求也将越来越高。 此次设计所做的题目是校徽内形设计，而整个校徽成品可用于，赠送于新入学的同学，或者是要离校的同学，或者是嘉宾，让他们为自己的母校留下美丽的怀念，为所到的学校留下一份珍贵的回忆；这样一来他们既有回忆的实物，当他们拿到这校徽时又何尝不是一件美事。此次所做的成品为金属，因此此次所做模具为冲压模具设计。 模具在我国被称之为“百业之母”，德国称之为“金属加工中的帝王”，有的国家甚至称之为印钞机；我相信我们的日常生活离不开他，模具会为其他行业奠定扎实的基础，也必将创造出属于他自己真实而又巨大的价值。 关键词：标志，高速度，高精度，高性能，依赖性，智能化，价值 ABSTRACT Mould tech
