摘要
本課題研究的內(nèi)容主要是設(shè)計一副生產(chǎn)軸承座的模具，采用復(fù)合模，該模具中落料凸模和凹模首先接觸條料，并與推件塊一起壓住條料，先落料，再拉深沖孔同時進(jìn)行，當(dāng)上?；爻虝r落料后的條料由剛性卸料板從凸凹模上卸下，成型零件由打料桿打下，手動取出制件，由于是手動取出，一定程度的影響了工作效率。本模具的材料利用率為63%，材料利用率一般。
制件的尺寸較大，對沖壓設(shè)備和模架的要求較高，模具的結(jié)構(gòu)也較為復(fù)雜，模具的制造成本也相應(yīng)提高。
本模具能夠滿足生產(chǎn)要求。
關(guān)鍵詞：復(fù)合模、剛性卸料、凸凹模

Abstract
This topic research content mainly is designs a production bearing seat the mold,Uses the superposable die,This mold declines the material raised mold and the concave mold first the contact bar material, And with pushes a block to suppress the strip material together,Falls the material first,Again also the drawing punch holes carries on, After top die return trip falls the material the strip material to unload the yard lumber by the rigidity to dismount from the convex-concave mold,Takes shape the components by to hit the material pole to overcome,Manual takes out the workpiece, Because is manual takes out,Certain degree influence working efficiency. This mold material use factor is 63%,The material use factor is ordinary. The workpiece size is big,Is high to the ramming equipment and a mold request,The mold structure is also complex,The mold production cost also correspondingly enhances.
This mold can satisfy the production request.
Key word:Superposable die, rigid ex-denning, convex-concave mold
