内容简介：

轴架冲压工艺及模具的设计学生姓名:李皓东 班级：0781052 指导老师：贺红林摘要: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。本课题就是将轴架作为设计模型，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。 首先，对轴架的工艺性能进行分析，提出了三种可行的冲压工艺方案。通过对三种方案的分析比较，最终确定采用第二种方案，选定“冲孔-弯曲-落料，级进模生产”的冲压工艺路线。然后，按选定的工艺路线进行主要参数的工艺计算。确定模具的结构。即模架型式、导向方式、毛坯定位、卸料、推料、压料、出件方式等。随后，确定模具主要零部件的结构与尺寸。并在此基础上绘制装配图和零件工作图。最后，确定压力机类型及主要参数。以达到预期效果。关键词：冲压模具 轴架 模具设计指导老师签名：Axis frame stamping process and die designStudent name:Li Haodong Class：0781052Supervisor:He Honglin Abstract: 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 stand as a design axis model, Die related knowledge as a basis to explain the design process of Die. First, the performance of the shaft frame analysis of the process, put forward three possible solutions stamping process. Through analysis and comparison of three programs, and ultimately determine the use of the second option, select Punching - Bending - Blanking, progressive die production of stamping process route. Then, according to the selected process route for the main parameters of the process calculation. Determine the structure of the mold. The mold pattern, oriented approach, rough positioning, unloading, pushing material, press materials, the pieces of methods. Subsequently, to determine the main components of the mold structure and size. On this basis, assembly drawing and parts on the working drawings. Finally, determine the type and presses the main parameters. To achieve the desir
