限位板沖壓成形工藝及模具設(shè)計
摘要：本設(shè)計的題目為限位板沖壓成形工藝及模具設(shè)計,體現(xiàn)了薄板類沖裁零件的要求、內(nèi)容及方向，具有一定的設(shè)計意義。通過對該零件模具的設(shè)計，進一步加強了本人沖壓模設(shè)計的基礎(chǔ)知識，為以后設(shè)計更復雜的沖壓模具做好了鋪墊并吸取了深刻的經(jīng)驗。
本設(shè)計運用沖壓成型工藝及模具設(shè)計的基礎(chǔ)知識，首先分析了沖裁件的沖壓工藝性，為確定沖裁工藝方案做好了準備；然后計算沖裁力和模具刃口尺寸，便于選取壓力機及確定工作零件的尺寸和結(jié)構(gòu)；最后分析了制件的特征，確定模具的設(shè)計參數(shù)、設(shè)計要點及推件裝置的選取。
本沖裁件上孔為非規(guī)則形狀的孔,為了便于沖孔凸模的加工，所以在設(shè)計時把沖孔凸模設(shè)計成直通式,然后,將其鉚接在凸模固定板上。此外,該制件的尺寸較大,為保證凹模的加工精度,在設(shè)計時應(yīng)將其設(shè)計成凹模組件。為了方便制件的取出，本副模具采用倒裝結(jié)構(gòu)形式,同時,為了簡化模具結(jié)構(gòu)采用彈性推件裝置。

Limit plate stamping process and die design
Abstract：The title of the design limit plate for stamping and die design process, reflects the type of sheet metal stamping parts requirements, content and direction of the design has a certain significance. Parts of the mold through the design, I have further strengthened the foundation for stamping die design knowledge, for the future design of more complex stamping die to do a good job of paving the way and draw a deep experience.
The design of the use of punch forming process and die design of the basic knowledge, the first analysis of the blanking process of stamping parts, stamping process planning in order to determine prepared; then calculated edge blanking and die size, easy to select the press and determine the size and structure of parts; the final analysis of the characteristics of parts, molds to determine the design parameters, design elements and push the select pieces of equipment.
Hole blanking pieces on this non-rules-shaped hole punch to facilitate the processing of punch, so when in the design of punch designed to punch straight-through, and then its riveting punch fixed in the board. In addition, the larger the size of parts, in order to ensure the accuracy of die processing, should be in the design of its components are designed to die. In order to facilitate the out parts, the Vice-die using flip-chip structure, at the same time, in order to simplify the use of flexible push mold structure installation
