殼體沖壓工藝及模具設(shè)計
摘 要:本設(shè)計題目是殼體落料拉深復(fù)合模,體現(xiàn)了帶窄凸緣筒形零件的設(shè)計要求、內(nèi)容及方向,具有設(shè)計意義。通過對該模具的設(shè)計,復(fù)習(xí)了我的沖壓模具設(shè)計的基礎(chǔ)知識,為今后設(shè)計更復(fù)雜的沖壓模具做好了鋪墊。
本設(shè)計運用沖壓工藝及模具設(shè)計的基礎(chǔ)知識,首先分析了制件的形狀及生產(chǎn)可行性,為合理選取沖壓工藝方案做好準(zhǔn)備;然后估算了落料毛坯的體積,便于排樣;最后分析模具結(jié)構(gòu),確定模具的設(shè)計參數(shù)、設(shè)計要點及卸料裝置的選取。
本制件是帶窄凸緣的筒形件,選擇合適的壓邊力是極為重要的,它具體應(yīng)在保證不起皺的前提下取最小值。卸料板在落料前兼起壓料作用。 本復(fù)合模具先由凸凹摸與落料凹模進(jìn)行落料工序,后由凸凹摸與拉深凸模進(jìn)行反向拉深工序。模具結(jié)構(gòu)屬于正裝式復(fù)合模,比較適宜本制件的成形。此外,在排樣的工作中力求板材利用率達(dá)到較高的水平。

The Pressing Process and Die Design for the Shell
ABSTRACT: The topic of the design is a shield produced by compound blanking and drawing dies, it is according to the requirements 、the contents、also the directions of cylindrical part which has a narrow flange. And it is of great significance. Throughing the die design of this part, my foundation knowledge of die design was enriched a lot. It will be helpful for my later's die-designing which are more difficult, in addition, I have gain countless experience .
The design using blanking technique and foundation knowledge of die design, first by analysising the shape of the part and feasibility of producing. All have done are making preparation for reasonable selection of blanking technique scheme . Then calculated the volume of the blank flat,so it is simple for layout designing. Finally anlysised the die structure,confirmed the die designing parameter 、designing essences and selecting tripper.
This part is a cylindrical part with a narrow flange, so tomake a suitable pressure-pad-force is very important. After make sure it will not wrinkle, it should be selected a minimum. The stripper also is act as a pressure-pad. First the compound die and blanking die doing the blanking process, then the compound die and the drawing punch doing the reverse drawing process, the structure is belonging to the simple compound die .It is quite suitable for this part 's forming. Furthermore, during the layout-design I try my best to make the sheet-utilization at a rather hign level.
Keywords: compound blanking and drawing dies reverse drawing drawing clearance narrow flange tubular
