摘 要
本次課程設(shè)計的任務(wù)我選的是接觸環(huán)零件沖壓工藝分析和模具的具體結(jié)構(gòu)設(shè)計。通過查閱了相關(guān)文獻資料，對接觸環(huán)零件進行工藝性分析，選擇并確定符合于給定條件的最優(yōu)工藝方案，及進行了工藝與設(shè)計的有關(guān)計算，如：選擇基本工序，確定其順序、工序數(shù)目及工序組合形式。介紹了主要零部件的設(shè)計理念，詳細剖析了設(shè)計過程中一些思路，以及某些非標準零件的使用特點。闡述了工位級進模的設(shè)計要點, 使產(chǎn)品質(zhì)量達到設(shè)計要求。然后以此為基礎(chǔ)，設(shè)計出沖壓模具主要零件的結(jié)構(gòu)。并在設(shè)計中，介紹了零件的排樣圖、定位設(shè)計、沖裁力的計算和壓力中心的計算。
分析了沖模模架的基本類型，討論了沖模模架的技術(shù)要求，介紹了標準模架的裝配工藝。并指出了模架裝配時的注意事項。條料的步進定位是一個很重要的工序，其對工件的精度影響很重要，因此對其設(shè)計的準確性與標準性對模具既有利于模具維修的規(guī)范化，也為整個模具的順利生產(chǎn)打下了一個良好的基礎(chǔ)。同時凸、凹模結(jié)構(gòu)對產(chǎn)品生產(chǎn)質(zhì)量影響也很大，在提高經(jīng)濟效益和降低成本的前提下，設(shè)計出合理而簡單的凸、凹模結(jié)構(gòu)是設(shè)計中的重要環(huán)節(jié)。

Abstract:

The design is focus on both the analysis of Pressing technics of the contact plate and the particular configuration design of die. According to check with a great deal of reference details . It is a must to base on the technical analysis of the patch, then choose a best craft procedure to a given project. For instance, basic procedure's choosing, basic procedure's sequence confirmation , the amount of the working procedure and the format of the procedure combination. Presentation of the main components of the design concept, a detailed analysis of the design process in a number of ideas, as well as the use of certain features of non-standard parts On-position progressive die design features, so that the quality of products meet the design requirements. And then as a basis for designing the main parts stamping die structure. And design, introduced the nesting parts map, location design, the calculation of punching force and the calculation of center of pressure.
Analysis of the die of the basic types of mold, die mold discussed the technical requirements on the standard mold of the assembly process. And pointed out that when the mold assembly of attention. Be expected to step positioning is a very important process, and its impact on the accuracy of the workpiece is very important, so the accuracy of their design on the mold with the standard of maintenance of both the standardization of mold, but also for the smooth production of the mold and lay a good foundation. At the same time, convex, concave mold structure of the product quality of a great impact in improving the economic efficiency and reduce costs under the premise of the design of a reasonable and simple, convex, concave mold structure is an important part of the design.
Key words: contact chip; progressive die; plastic; nesting; Inserts; die mold; technical conditions; assembly process
