前端蓋沖壓成形工藝及模具設(shè)計
摘要：本設(shè)計的題目為前端蓋沖壓成形工藝及模具設(shè)計的設(shè)計,體現(xiàn)了薄板類沖裁零件的要求、內(nèi)容及方向，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，為設(shè)計更復(fù)雜的沖壓模具做好了鋪墊和吸取更深刻的經(jīng)驗。
本設(shè)計運用沖壓成形工藝及模具設(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。
本沖裁件規(guī)則形狀的圓,為了便于落料凸模的加工，所以在設(shè)計時把落料凸模設(shè)計成直通式。此外,該制件的尺寸較大,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。

The front cover stamping process and die design
Abstract: This design topic for the front cover design process and die design ofstamping forming, content and direction of the sheet metal blanking parts requirements, the design of a certain significance. Through the design of the die parts, further strengthen the stamping die design of the basic knowledge, which paves the way for more profound experience and lessons for the design of more complex stamping die.
The design of the stamping process and die design of the basic knowledge, the first analysis of the stamping process of blanking, punching process scheme for determining ready; then the calculation of blanking force and die cutting edge size, easy to select the press and determine the size and structure of working parts; finally analyses the product characteristics, determination of designparameters, die design and the pushing device selection.
The blanking piece shape circle, in order to facilitate the processing of blanking punch, so in the design of the blanking punch is designed through type. In addition, the size of the workpiece is larger, the mold using flip chip structure, at the same time, in order to simplify the mould structure with elastic pushing device.
