锁壳冷冲压模具设计 摘 要 1 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，近些年，冷冲模具在整个模具行业中所占比例已上升到50%左右， 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10%以上的较高速度的发展。国内冷冲模具市场以冷冲模具需求量最大，其 中发展重点为工程冷冲模具。 冲裁成型是冷冲成型的一种重要方法，它主要适用于金属材料的成型，可以 一次成型形状复杂的精密零件。本课题就是将锁壳冷冲压模作为设计模型，将冲 裁模具的相关知识作为依据，阐述冷冲压模具的设计过程。 本设计对锁壳冷冲压模进行的冷冲压模的设计，对工件结构进行了工艺分析。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。 最后用autoCAD 绘制了一套模具装配图和零件图。 本课题通过对锁壳冷冲压模的冷冲压模具设计，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。 关键词:冲压模具；冲裁成型；模具设计 Abstract In recent years, Chinas household electrical appliance industry in the development of high-speed tooling industry, in particular, have raised Die growing demands in recent years, the entire Die in a proportion of trade has risen to around 50 percent, according to the relevant Experts predict that in the next few years, China will continue to Die with industry to maintain an average annual growth rate reached over 10 percent of high speed development. Die with the domestic market to Die with the greatest demand, which focus on the development of a project Die. Blanking is forming a cold-forming an important method, which apply mainly to the forming of metal materials, forming a complex shape of the precision components. The issue is to lock shell cold stamping die as a design model, will be punching die of related knowledge as the basis on cold stamping die design process. The design of the lock shell of the cold stamping die of cold stamping die design, 2 the structure of the workpiece Technology Analysis. Defined the design, determine the process of stamping and forming part of the specific details of the calculation and verification. So the structure can be d
