1、 内容提要 模具工业是现代工业发展的基础，冲压模具是模具工业的重要组成 部分。近年来，与机械相关的各个行业都越来越重视模具的设计与应用， 不仅是因为模具已发展成为一项比较成熟的共性技术，同时还因为模具 在现代工业中发挥越来越重要的作用。 在这次毕业设计中，先介绍了卡板的结构，对其工艺特点进行分析， 再根据其结构特点对模具进行设计。其中重点阐述了成形该零件的级进 模的排样设计、工位设计、模具总体结构设计、模具凸、凹模设计、固 定板设计及抬顶料装置、卸料板结构及各零部件材料、热处理技术要求 等。还介绍了单工序弯曲模的设计。该模具结构简单，加工质量好，生 产效率高。 设计过程中，不可避免的遇到一些困
2、难，但是通过努力最终得以解 决。这次设计是对模具设计的一次全面实践，相信对未来自己从事的工 作一定会有相当大的帮助。 关键字：冲压模具，卡板，级进模 Abstract The mould industry is the foundation of the modernization industry, and stamping die plays a very important part in die industry. In recent years, each industry that related with mechanics is all paying more and more
3、 attention to the design and application of mould. That is not only because mould has already been developed into one ripe generality technology, but also because mould plays a more and more important role in modernization industry. In the graduation project, the structure of clip board is introduce
4、d at first. The technological characteristics of the clip board is analyzed. The die of the clip board is designed according to its structural characteristics. The layout design of the progressive die for forming the part and the designs of the work positions, general structure of the die, the punch
5、 and matrix of the progressive die, retaining plate, the structure of the block lifting device, the structure of the stripping plate, and the technical requirements for the material and heat treatment of each component are mainly stated. In addition, the design of the single-operation die for bendin
6、g is introduced. The die structure is simple, the processing quality of the die is good and the productivity is high. During the design, unavoidable I met some difficulties in the design, but I have conquered them with my assiduity. Its my first time to practice of the design of mold, so I believe that it will be great helpful for my job in the future.
