油封鋼圈沖壓工藝及模具設(shè)計
摘要: 本設(shè)計題目為油封鋼圈沖壓工藝及模具設(shè)計，體現(xiàn)了典型復(fù)合模具的設(shè)計要求、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(jìn)一步加強了設(shè)計者沖裁模設(shè)計的基礎(chǔ)知識，為設(shè)計更復(fù)雜的沖裁模具做好了鋪墊和吸取了更深刻的經(jīng)驗。
本設(shè)計充分運用沖裁工藝及模具設(shè)計的基礎(chǔ)知識，首先分析了板材的性能要求，為選取模具的類型做好了準(zhǔn)備；然后計算了沖裁件的沖裁力，便于選取壓力機(jī)噸位及確定壓力機(jī)型號；最后分析了沖裁件的特征，便于確定模具的設(shè)計參數(shù)、設(shè)計要點及卸件裝置。
本設(shè)計采用正裝復(fù)合模，通過落料、拉伸、沖孔、切邊工序在一次行程中完成制件的成形。模具采用后側(cè)導(dǎo)柱導(dǎo)向方式，導(dǎo)料采用導(dǎo)料板，送進(jìn)步距控制采用擋料銷，采用固定卸料、剛性打桿、打板卸料方式。如果不考慮經(jīng)濟(jì)成本時，采用級進(jìn)模設(shè)計會更好。

Steel ring seal stamping process and die design
Abstract: The topic of design for the steel ring seal stamping process and die design, reflects the typical mold of the design requirements, the contents and direction of a certain design significance. Parts of the mold through the design, the designer has been further strengthened Die design the basic knowledge to design more complex punching die to pave the way and the lessons more profound experience.
Make full use of the design process and die design blanking the basis of knowledge, the first sheet of the performance requirements, select the type of mold prepared for the then calculate the blanking of the punching power, for select press tonnage and determine Press models; blanking of the final pieces of the characteristics identified die for the design parameters, design features and dumping of pieces of equipment.
This design is used with compound die by blanking, stretching, punching, trimming process in a trip to complete the forming parts. Die guided by rear-oriented approach, guided by I. Liu board materials, send progress expected from the control of a block sale, unloading a fixed, rigid-playing, playing board unloading way. If we do not consider the economic costs, the use of progressive die design will be even better.
