特殊块冲裁工艺分析及模具设计
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。

Abstract
With the development of mold manufacturing technology gradually, the development gradually from manual mode to software aided design. Cold die is one of them.
Graduation design is a practical teaching link after the theory teaching of mould specialty. It is a general test of the knowledge learned and a practical exercise before going to the job. The purpose is to integrate the theoretical and practical knowledge of the course and design a complete set of mold training, training and improvement of theirwork ability. To consolidate and expand the content of the course of mould specialty, and to master the methods, steps and related technical specifications of mould design and manufacture. Skilled access to relevant technical information. Grasp the basic skills of mold design and manufacturing, such asworkpiece process analysis, mold process plan argumentation, process calculation, processing equipment selection, manufacturing process, collecting and consulting design data, drawing andwriting design technology documents.
The actual situation of equipment and personnel for stamping process and die design should be combinedwith the factory, from the production quality, production efficiency, production cost, labor intensity, environmental protection and all production safety consideration, choose the advanced technology, reasonable economy, safety and reliable use of process and die, in order to make the stamping parts the production to meet the technical requirements on the design drawing, stamping process cost is reduced and ensure safe production as soon as possible.
With the rapid development of the mold, in the modern industrial production, the mold has become an indispensable important process equipment for the production of all kinds of industrial products. This graduation project is carried out on the basis of all mechanical courses. It is an examination of my comprehensive ability, a comprehensive application of my knowledge and a review and examination of my knowledge.
This design is guided by the teacher's careful and patient guidance. It carries out a comprehensive and careful analysis of the economy of mould, the life of mould, the production cycle and the cost of production. Here, Iwould like to express my sincere thanks to them forwhat they have taught me.
Keywords: process calculation, stamping process, die design
