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,通过侧罩冲压工艺规程编制与模具设计,设计出两副完整的模具,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。

Abstract
With the technological development of die and mould manufacturing, it has gradually changed from manual mode to assistant design using high-tech methods such as software. Cold stamping die is one of them.
Graduation design is a practical teaching link after theoretical teaching of die and mould specialty. It is a general test of the knowledge learned and a practical exercise before going towork. The aim is to design two sets of complete dies by synthesizing the theoretical and practical knowledge of the course, compiling the side cover stamping process regulations and designing the die, so as to cultivate and improve theirworking ability. Consolidate and expand the contents learned in the course of mould specialty, master the methods, steps and related technical specifications of mould design and manufacture. Skillful access to relevant technical information. Master the basic skills of die design and manufacturing, such as process analysis of parts, demonstration of die process plan, process calculation, selection of processing equipment, manufacturing process, collecting and consulting design information, drawing and compiling design technical documents, etc.
The design of stamping process and die should be combinedwith the actual situation of equipment and personnel in the factory, considering comprehensively the quality of parts, production efficiency, production cost, labor intensity, environmental protection and safety of production, and selecting technological schemes and dieswith advanced technology, reasonable economy, safe and reliable use, so as to ensure the production of stamping parts to achieve the design drawings. Various technical requirements, as far as possible to reduce the cost of stamping process and ensure safe production.
Keywords: side cover; stamping process; die design; equipment selection
