Abstract
In this paper, the application of the professional courses of theoretical and practical knowledge of the production of a cold stamping die design of the practical training of students so as to nurture and enhance the ability to work independently, Consolidation and expansion of the cold stamping die design, the content of classroom teaching, master of cold stamping die design methods and steps. Cold stamping die design to master the basic skills to understand how to mold parts of the process of analysis and how to determine the technology program to understand the basic structure of the mold to enhance the computing power, graphics capability, familiar with the norms and standards, At the same time, there are various courses related to a comprehensive review, the ability to think independently improved. . The use of drawing die design and manufacture of simple mold. Drawing effective and can greatly improve the production efficiency. The design is divided into 5 chapters on analysis of the product technology, technical computing, design templates and components, mold legislation and other issues group.We should understand the product uses, and the process of stamping parts and dimension tolerance level analysis, some unreasonable or stampingprocess of the bad ones, and we need to mapping tool to improve the overall map and non-standard Parts items.Keywords Process Analysis Process Design Mold Group
