落料、沖孔復合模設計
摘要
(中文)
本模具設計題目為落料,沖孔復合模,此零件需二道工序完成.體現(xiàn)了復雜零件的設計要求,內(nèi)容及方向.具有一定的設計意義,通過對該零件模具的設計進一步加強了設計者沖壓模具設計的基礎知識,為設計更復雜的沖壓模做好了鋪墊和吸取了更深該的經(jīng)驗.
本設計運用沖壓模具設計與制造工藝基礎知識,首先分析了零件的外形,尺寸,精度要求,進行了工藝分析,考慮到此零件為零件,因此采用復合模工藝方案.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)設計,卸料裝置的設計以及固定零件的設計與運用.
本模具的特點是落料,沖孔復合模.
此時由落料凹模,凸凹模進行落料,然后沖底孔.
關(guān)鍵詞: 復合模 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
