内链板复合模具设计
摘要
随着模具制造的技能化逐步向科学化发展，逐渐由以前手动方式发展为利用软件等高科技方式来辅助设计的完成。冷冲模是其中的一种。
设计是在模具专业理论教学之后进行的实践性教学环节。是对所学知识的一次总检验，是走向工作岗位前的一次实战演习。其目的是，综合运用所学课程的理论和实践知识,设计一副完整的模具训练、培养和提高自己的工作能力。巩固和扩充模具专业课程所学内容，掌握模具设计与制造的方法、步骤和相关技术规范。熟练查阅相关技术资料。掌握模具设计与制造的基本技能，如制件工艺性分析、模具工艺方案论证、工艺计算、加工设备选定、制造工艺、收集和查阅设计资料，绘图及编写设计技术文件等。
冲压工艺与模具设计应结合工厂的设备、人员等实际情况，从零件的质量、生产效率、生产成本、劳动强度、环境的保护以及生产的安全性各个方面综合考虑，选择技术先进、经济合理、使用安全可靠的工艺方案和模具，以使冲压件的生产在保证达到设计图样上的各项技术要求，尽可能降低冲压的工艺成本和保证安全生产。
随着模具的迅速发展，在现代工业生产中，模具已经成为生产各种工业产品不可缺少的重要工艺设备。这次设计是在学习完所有机械课程的基础上进行的，是对我综合能力的考核，是对我所学知识的综合运用，也是对我所学知识的回顾与检查。
本次设计是在指导老师认真、耐心的指导下，对模具的经济性、模具的寿命、生产周期、及生产成本等指标下进行全面、仔细的分析下而进行设计的。在此,我表示衷心的感谢他们对我的教诲。

Summary
With mold manufacturing skills to the scientific development of progressive, gradual development from the previous manually using software and other high-techways to assist the design is complete. Die is one of them.
Graduation is a practical teaching after teaching the theory of professional mold. Is the knowledge of the lump-sum test, is a combat exercise towork before. Its purpose is the integrated use of theoretical and practical knowledge of the course of study, a complete mold design training, culture and improve their ability towork. Consolidation and expansion of mold professional courseswhat they learn, master mold design and manufacturing methods, procedures and relevant technical specifications. Skilled access to relevant technical information. Master mold design and manufacturing of basic skills, such as parts of the process analysis, mold technology demonstration program, process calculation, the selected processing equipment, manufacturing processes, and access to design data collection, preparation of design drawings and technical documents.
Stamping process and die design should be combinedwith the actual situation of the factory equipment, personnel, etc., from the quality of parts, productivity, production costs, labor intensity, environmental protection and security of all aspects of the production account, choose the advanced technology, economic rationality, safe and reliable use of the scheme and the mold to make stamping parts production guarantee the achievement of the technical requirements of design drawings on minimizing process costs punched and ensure safety in production.
With the rapid development of the mold, in modern industrial production, the mold has become the production ofvarious industrial products indispensable process equipment. The graduation project is based on the study completed all courses conducted on machinery, comprehensive ability is my assessment, is the integrated use of my knowledge, but also on the knowledge I review and inspection.
This design is under the guidance of teachers serious, patient guidance of the lower mold economy, life of the mold, the production cycle, and the cost of production and other indicators to conduct a comprehensive, detailed analysis carried out under the design. Here, I express my heartfelt thanks for their teachings.
Keywords:
