 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
