摩托车离心块固定板冲压工艺与模具设计 PAGE PAGE 22 摩托车离心块固定板冲压工艺与模具设计 中文摘要及关键词 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。 本次毕业设计是完成摩托车离心块冲压工艺及模具设计。采用落料、拉深、冲孔、修边工艺。设计中分析了工件的冲压工艺性，计算了毛坯排样、冲压力、刃口尺寸计算等。进行了模具总体结构、主要零部件的设计，绘制了落料、拉深、冲孔复合模、修边的单工序模具装配图和零部件图。 本课题通过对摩托车离心块固定板的设计，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；冲压成型；模具设计 Abstract In recent years, the rapid development of Chinas household electrical appliance industry mould industry, especially cold blunt mould put forward more and more high demand, in 2004, cold in the whole mold industry rush mold the proportion of has greatly rising, experts predict, in the next few years, China cold blunt mould industry will continue to keep an annual growth rate of 15% or so of the high speed development. Stamping forming is the metal forming a kind of important method, it is mainly applied to materials softer metal forming, can be a complex shape of precision stamping forming. This topic is will petrochemical, chemical, electric power industries of the flange gasket seal structure design model, as will the related knowledge of cold blunt mould as basis, this paper expounds the design process of cold blunt mould. The graduation design is complete motorcycle centrifugal block stamping process and mold design. Adopt blanking, deep drawing, punch, deburring process. In the design of workpiece stamping technology analysis, calculated blank layout, blunt pressure, the blade size calculation, etc. The major parts of the overall structure, mould design, painted blanking, deep drawing, punching composite modulus, trimming single procedure mold assembly drawing and parts drawing. This topic through centrifugal blocks of motorcycle fixed board design, strengthening and deepening the knowledge learnt, achieved satisfactory effect, achieve the expected design int
