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。

ABSTRACT
Mould technology level is a measure of a country manufacturing level one of the important marks, mold is an important component of the high and new technology industry, is the foundation of industrial production equipment. Mold technology is a comprehensivevery strong precision assembly technology based process, involving new technologies, new processes, new materials and new equipment development and popularization and application; Is metallurgy, materials, measurement, electromechanical integration and many disciplines such as casting, forging, heat treatment, machining, testing and other type ofwork together to build the system engineering. With mold production productswith high efficiency, high consistency, high accuracy, high complexity, low consumption, etc. Based on mould manufacturing industrywith high and new technology industry to become the industry.
Mold is to keep of the average annual growth in our country,with the reform and opening brought by the economic hair pieces, mold output in our country after Japan, after the United States. Around in shenzhen and the pearl river delta region gathered more than mould enterprise, the staff more than people. Has been held five sessions in shenzhen south China international mold exhibition, attracted countries and regions more than enterprises to participate in, is now China's most professional, the internationalization level of mould industry exhibition. Guangdong is set to become theworld's hardware mold center. Mold is more and more developed countries transfer in our country, exacerbating the lack of professional population. As people living standard rise, people for automobile industry, electronics, healthcare, office areas, dependent increase, in the field of aviation and the industry's dependent for mould is quite big, such as: upgrading of automobile, aviation of sheet metal forming, electronics, plastic molding, etc. Comparedwith the developed countries to build our country mold innovative enough, some still don't have advanced technology, the standardization of mold is in perfect, some still need to import advanced equipment, and the most advanced technology and equipment in a state-owned enterprises, the production conditions are still lagging behind, some small companies still continue to use the manual+ mechanization; For large, high precision mold still need to import, and the design of the mould from the service life, performance more than still lag behind developed countries; However in most of the tools used in the advanced materials and processing, still need to import..
Looking forward to the future, as time progress, the new age people higher requirement on mold, processing on the pursuit of: high speed, high precision, high quality; Use on the pursuit of: high performance; Of course in the face of these new slogan put forward by new era, the traditional processingway is difficult to meet the needs of mold personnel; As the mold of intelligent and popularway some processing, now some experts predict the mold processing technologywill bewill be some technical development toward the following: 1. Promoting technology; 2. High speed milling machining technology; 3. Die scanning and digital technology; 4. The electrical discharge milling machining technology; 5. Improve the standardization degree of the die; 6. High quality material surface treatment technology; 7. The mold polishing automation, intelligent technology; 8. Automatic mould processing technology; 9. printing. The service life of the mold in the future no matter from, processing performance is far superior mould now. Of course for the future demands of thewhole mould personnel alsowill more and more high..
Within the topic of the graduation design do is crest shape design, and the crest can be used for finished products, presented in the new school classmate, or classmate, is to leave or be guests, let them for their Alma mater, leave the beautiful miss, for leave to school a precious memory; So they both physical memory, sowhen they get the crest is a beautiful thing. Do the finished product is metal, so do the mold for stamping die design.
Mold known as"the mother of all sectors in our country, Germany is called" emperor"in metal processing, some countries even called a printing press; I believe in our daily life, so he is moldwill lay a solid foundation for other industry,will create his own truth and greatvalue.
Keywords: mark, high speed, high precision, high performance, dependency, intelligence, andvalue.
