落料、沖孔復(fù)合模設(shè)計
摘要
(中文)
本模具設(shè)計題目為落料,沖孔復(fù)合模,此零件需二道工序完成.體現(xiàn)了復(fù)雜零件的設(shè)計要求,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(jìn)一步加強(qiáng)了設(shè)計者沖壓模具設(shè)計的基礎(chǔ)知識,為設(shè)計更復(fù)雜的沖壓模做好了鋪墊和吸取了更深該的經(jīng)驗.
本設(shè)計運(yùn)用沖壓模具設(shè)計與制造工藝基礎(chǔ)知識,首先分析了零件的外形,尺寸,精度要求,進(jìn)行了工藝分析,考慮到此零件為零件,因此采用復(fù)合模工藝方案.然后根據(jù)零件的外形尺寸計算毛坯總體尺寸,設(shè)計壓力中心最后計算出工作部分尺寸,模具總體尺寸,總體尺寸包括工作零部件的結(jié)構(gòu)設(shè)計,卸料裝置的設(shè)計以及固定零件的設(shè)計與運(yùn)用.
本模具的特點(diǎn)是落料,沖孔復(fù)合模.
此時由落料凹模,凸凹模進(jìn)行落料,然后沖底孔.
關(guān)鍵詞: 復(fù)合模 落料凸凹模
The Punch Holes Superposable Die Desig
Abstract
This mold design topic for the punch holes superposable die, this components need two working procedures to complete. Has manifested the complex components design request, the content and the direction. Has certain design significance, through further strengthened the elementary knowledge to this components mold design which the designer ramming mold designs, for designed more complex flushes the die to complete the upholstery and to absorb a deeper this experience.
This design utilization ramming mold design and the manufacture craft elementary knowledge, has first analyzed the end cover components contour, the size, the precision request, has carried on the craft analysis, considered this components are the circular components, Then the basis components external dimensions computation semifinished materials overall size, a design the center of pressure last count is present at work makes the partial sizes, the mold overall size, the overall size including the work spare part structural design, the dumping device design as well as the fixed components design and the utilization.
This mold characteristic is the punch holes superposable die.
this time by falls the material concave mold, the convex-concave mold carries on falls the material, then flushes the bottom hole.
Key word: The drawing mold superposable die convex-concave mold
