螺母盒零件冲压工艺与冲模设计
 摘要：近年来，我国家电工业的高速发展对模具工业，尤其是冷冲模具提出了越来越高的要求，2004年，冷冲模具在整个模具行业中所占比例已大大上升，据有关专家预测，在未来几年中，中国冷冲模具工业还将持续保持年均增长速度达到15%左右的较高速度的发展。
  冲压成型是金属成型的一种重要方法，它主要适用于材质较软的金属成型，可以一次成型形状复杂的精密制件。本课题就是将石化、化工、电力等行业的法兰密封结构中的垫片作为设计模型，将冷冲模具的相关知识作为依据，阐述冷冲模具的设计过程。
  本设计对螺母盒进行的级进模设计，利用Auto CAD软件对制件进行设计绘图。明确了设计思路，确定了冲压成型工艺过程并对各个具体部分进行了详细的计算和校核。如此设计出的结构可确保模具工作运用可靠，保证了与其他部件的配合。并绘制了模具的装配图和零件图。
  本课题通过对螺母盒的冲压模具设计，巩固和深化了所学知识，取得了比较满意的效果，达到了预期的设计意图。

Nut box parts stamping process and die design
Abstract：In recent years,the rapid development of China's household electrical appliance industry of mold industry,especially Die with the increasing demands put forward in 2004,Die in the proportion of the proportion of the entire mold industry has been greatly increased,experts predict,In the next few years, China will continue to maintain industrial Die average annual growth rate reached 15% of the high rate of development. In the next few years, China will continue to maintain industrial Die average annual growth rate reached 15% of the high rate of development. In the next few years, China will continue to maintain industrial Die average annual growth rate reached 15% of the high rate of development. Stamping is an important method of metal forming, it is mainly applied to relatively soft metal forming, can be a molding of precision parts of complex shape. This topic is to petrochemical, chemical, electric power industries gasket flange structure as a design model, Die related knowledge will be used as the basis to explain Die design process. The design of the nut box for the progressive die design, the use of Auto CAD software to design parts drawing. Clear design ideas, determine the process of stamping and forming part of the various specific details of the calculation and verification. The structure of such a design die is used to ensure reliable, to ensure coordination with other components. And the mapping of the mold assembly and part drawings. The topic box on the nut stamping die design, consolidate and deepen the knowledge, and achieved satisfactory results, to achieve the desired design intent.
