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。
本次设计课题为T形连接件冲压成形工艺与模具设计，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.
冲模是模具设计与制造专业的主要专业课程之一。它具有很强的实践性和综合性，通过学习这门课程，使我对冲压模具有了新的认识，从中也学到了不少知识，激发了我对冲压模具的爱好。

Abstract
With the development of mold manufacturing technology gradually, it has gradually developed from manual mode to software aided design. Cold die is one of them.
Graduation design is a practical teaching link after the theoretical teaching of mold specialty. It is a general test of knowledge and a practical exercise before heading towork. The purpose is to design a complete mold training, train and improve theirworking ability by using the theory and practice knowledge of the course comprehensively. Consolidating and expanding the contents of the mold specialized course, mastering the methods, steps and relevant technical specifications of mold design and manufacturing. Skilled access to relevant technical information. Master the basic skills of mold design and manufacture, such as technical analysis of parts, demonstration of mould process plan, process calculation, processing equipment selection, manufacturing process, collection and consulting design data, drawing andwriting design technical documents.
The stamping process and die design should be combinedwith the actual conditions of the equipment and personnel of the factory. From the aspects of the parts quality, production efficiency, production cost, labor intensity, environmental protection and production safety, the technology is advanced, economical and safe to use. The production of stamping parts is guaranteed to meet the technical requirements of the design drawings, minimizing the cost of stamping process and ensuring safety in production.
With the rapid development of mold, mold has become an indispensable and important process equipment for producingvarious industrial products in modern industrial production. This graduation design is carried out on the basis of all the mechanical courses. It is the assessment of my comprehensive ability, the comprehensive application of my knowledge and the review and examination of the knowledge I have learned.
The design is designed for the stamping process and die design of T- shaped joint. Under the guidance of the teacher's careful and patient guidance, it is designed under the comprehensive and careful analysis of the economy, die life, production cycle and production cost. Here, Iwould like to express my heartfelt thanks to them for teaching me.
Stamping die is one of the main professional courses of mould design and manufacturing specialty. It has a strong practicality and comprehensiveness. By studying this course, I have a new understanding of the stamping die and learned a lot of knowledge from it,which inspired me to love the stamping die.
Keywords: process calculation; T shape connector; stamping forming; die design
