T型铁芯片车腻裁模论文.doc

摘 要 本论文设计的是T型铁芯片冲裁模，重点是在分析冲裁变形过程及冲裁件质量影响因素的基础上，主要内容包括冲裁件的工艺性分析、确定冲裁工艺方案、选择模具的结构形式、进行必要的工艺计算、选择与确定模具的主要零部件的结构与尺寸、校核模具闭合高度及压力机有关参数、绘制模具总装图及零件图。 该冲裁模是利用级进模生产，级进模又称为多工位级进模、连续模、跳步模，它是在一副模具内，按所加工的工作分为若干等距离的工位，在每个工位设置一个或几个基本冲压工序，来完成冲压工作某部分的加工。被加工材料，事先加工成一定宽度的条料，采用某种送进方法，每次送进一个步距。经逐个工位冲制后，便得到一个完整的冲压工件。在一副级进模中，可以连续完成冲裁、弯曲、拉深、成形等工序。一般来说，无论冲压零件形状怎么复杂，冲压工序怎样多，均可用一副级进模冲成完成。 关键词： 级进模; T型铁心片; 排样 ABSTRACT This paper focuses on the analysis and blanking blanking deformation on the basis of quality factors, mainly including blanking process of analysis to determine the blanking process plan, select the mold structure, the necessary process calculation, Selection and determination of the main components of the mold structure and size, check the height and press the mold closing argument, drawing die assembly drawings and part drawi. This thesis is the T core disk, using the progressive die production. Progressive die, also known as multi-position progressive die, progressive die, progressive die, which is a mold, according to the processing work is divided into a number of equidistant station, at each station to set up a or a few basic stamping process to complete the punching of a part of the process. Is processed materials, prior processed into a certain width strip, using a feeding method, taken a step away from each. The punching station one by one, they get a complete stamping parts. In a progressive die, you can complete a row blanking, bending, deep drawing, forming and other processes. In general, no matter how complex the shape of stamping parts, stamping process how much, which can be washed into a progressive die to complete.
