內(nèi)容提要

 模具工業(yè)是現(xiàn)代工業(yè)發(fā)展的基礎(chǔ)，沖壓模具是模具工業(yè)的重要組成部分。近年來，與機械相關(guān)的各個行業(yè)都越來越重視模具的設(shè)計與應(yīng)用，不僅是因為模具已發(fā)展成為一項比較成熟的共性技術(shù)，同時還因為模具在現(xiàn)代工業(yè)中發(fā)揮越來越重要的作用。
 在這次畢業(yè)設(shè)計中，先介紹了卡板的結(jié)構(gòu)，對其工藝特點進行分析，再根據(jù)其結(jié)構(gòu)特點對模具進行設(shè)計。其中重點闡述了成形該零件的級進模的排樣設(shè)計、工位設(shè)計、模具總體結(jié)構(gòu)設(shè)計、模具凸、凹模設(shè)計、固定板設(shè)計及抬頂料裝置、卸料板結(jié)構(gòu)及各零部件材料、熱處理技術(shù)要求等。還介紹了單工序彎曲模的設(shè)計。該模具結(jié)構(gòu)簡單，加工質(zhì)量好，生產(chǎn)效率高。
 設(shè)計過程中，不可避免的遇到一些困難，但是通過努力最終得以解決。這次設(shè)計是對模具設(shè)計的一次全面實踐，相信對未來自己從事的工作一定會有相當大的幫助。

卡板沖壓工藝及模具設(shè)計

 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 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 introduced 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 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 bending 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. It’s 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.
