摘要：本课题的主要研究内容是对弯曲铁芯多工位级进模的设计，设计包括冲裁件工艺分析、冲压工艺方案的设计以及排样方案的确定和冲压力的计算，同时可以熟悉冲压模的基本结构。这个课题的设计形状相对还是比较简单的，同时也需要从材料、精度、尺寸等方面考虑设计出不同的方案，然后找出一套最适合的方案。57179

近年来，在科学发展观的指导下，制造业进入了一个新的发展阶段，在冲压工艺和模具技术的发展中取得了显著的进步。我在综合自己今后的工作和发展方向的因素考虑后，在这次毕业设计中我选择了冲孔、切料、折弯、落料这一典型级进模结构进行设计，以此来巩固自己的专业知识。

本说明书共有六章。第一章简要介绍了模具行业的发展现状，和未来的大致发展趋势。第二章— 第五章，根据模具设计的基本步骤，分别进行了分析工艺、计算工艺、设计与计算主要零部件和选择冲压设备，最后对装配图和零件图进行了讨论。本说明书的最后一章总结了设计中遇到的问题和经验。说明书最后附有为本设计提供参考依据的文献。

 Design of multi position progressive die bending core

Abstract: the main research contents of this topic is of bent core multi position progressive die design, including the design of the blanking process analysis, the stamping process design and layout scheme of determining and pressure calculation, also can be familiar with the basic structure of the stamping die. The shape of the subject design is relatively simple, but also need from the material, size precision, etc. Considering the different design schemes, and then find a set of the most suitable solution.

In recent years, in the Scientific Outlook on Development under the guidance of the manufacturing industry has entered a new stage of development, has made significant progress in the development of stamping process and die technology. I comprehensively consider the factors of their future work and direction of development, in the graduation design I chose punching and cutting material, bending, fall material, which is a typical progressive die structure design, in order to consolidate their professional knowledge.

There are six chapters in this manual. The first chapter briefly introduces the current situation of the development of mold industry, and the general trend of development in the future. In the second chapter, the fifth chapter, according to the basic steps of the mold design, respectively, were analysis technology, computing technology, design and calculation of main parts and stamping equipment selection, the last of the assembly drawing and parts drawing are discussed. The last chapter of this specification summarizes the problems and experiences in design. Finally, the specification is attached to the reference of the design.

Key words: continuous mode; material; precision; reference
