端蓋沖壓成形工藝及模具設計
?
摘 要:本次畢業(yè)設計的內容為用模具生產(chǎn)軸承座端蓋的坯件,制定出相關的工藝路線,設計出生產(chǎn)所用模具。工藝路線主要包括落料、拉深兩道工序,設計為落料拉深復合模。沖壓工藝的選擇是在查閱了相關資料和對產(chǎn)品外形成尺寸進行了仔細分析的基礎上制定的;沖壓模具的設計綜合考慮了經(jīng)濟性、零件的沖壓工藝性和復雜程度等諸多因素;產(chǎn)品毛坯的展開尺寸計算是在方便計算又不影響零件成型的前提下轉化為熟悉的模型進行的。模具主要部分零件給出了相應的尺寸計算,同時給出了詳細的零件結構設計,并附有相應的零件圖,最后根據(jù)零件結構設計和生產(chǎn)零件的要求生成了總裝配圖。
