汽车刹车片模具毕业设计.doc

浙江理工大学本科毕业论文 摘要 粉末冶金是一种不需要将材料融化的冶金方法，是冶金和材料科学的一个分 支。而随着经济的发展，粉末冶金工艺具有生产效率高、质量稳定、成本低以及 可加工复杂形状工件等一系列优点，使其在现代工业中的地位也越来越高。相应 的，粉末冶金模具作为现代高速成型技术在工艺装备中起到越来越大的作用。特 别是在汽车行业中应用的比例越来越重,是现代汽车行业发展的重要支柱之一, 现代工业发展的一个方向. 本次设计了一套汽车刹车片的压制模。本课题主要是查找刹车片的压坯到模 具模架的选择准则，了解各个零件的具体要求。从对零件压坯的尺寸，密度，质 量和高度等计算，来确定阴模与模冲的类型，再通过对压机的选择设计所需要的 模具，顶出方式的选择,加热方式的选择,加热元件规格的计算与选择，对模具的 材料进行选择,强度校核,粗糙度的确定,最后画出零件图和装配图。 关键字：粉末冶金；压制成形；刹车片模具 汽车刹车片模具设计 Abstract Powder metallurgy is a branch of metallurgy and materials science who is an undesirable material melting metallurgy method.With the development of economy,Because of powder metallurgy process with high efficiency, stable quality, low cost and can be processed with complicated shapes advantages,so that it’s position in modern industry are more and more important. Accordingly, powder metallurgy die as a modern high-speed molding technology play an increasingly important tole in the process equipment.Especially in the automotive industry, an increasing proportion of re-application,is one of the important pillars of the modern automobile industry and also is a direction of Modern industrial development. This design is a press die of brake pads.The project must basis on part’s size, density, height and mass to design the mild’s stamping type.Then basis on press machine to choice mold’s type. Then I choice the best way for pushing-out and boiling. Next step are Selecting the material of the mold and Strength check. The last way, I must determine the roughness and draw the parts and assembly drawings finally. Key Words:Powder metallurgy; stamping shape; Brake pads mold 浙江理工大学本科毕业论文 目 录 摘要 Abstract 第 1 章 绪论.................................................................................................................. 1 1.1 粉末冶金概述.................................................................................................................... 1 1.2 模具工业在现代工业国民经济中的地位........................................................................ 4 1.3 粉末冶金模
