金屬?zèng)_孔落料件沖裁模具設(shè)計(jì)說明書

1、331摘要沖壓模具在工業(yè)生產(chǎn)中應(yīng)用廣泛。沖壓模具的設(shè)計(jì)充分利用了機(jī)械壓力機(jī)的功用特點(diǎn)，在室溫的條件下對(duì)坯件進(jìn)行沖壓成形，生產(chǎn)效率提高，經(jīng)濟(jì)效益顯著。本零件采用的是倒裝復(fù)合模沖裁，主要要涉及到?jīng)_裁件工藝的分析，排樣的設(shè)計(jì)，排樣方法，搭邊值的計(jì)算，沖裁力的計(jì)算，模具壓力中心的計(jì)算，凸模與凹模刃口尺寸的計(jì)算，模具的總體設(shè)計(jì)，主要零部件的設(shè)計(jì)，模具總裝配圖的繪制，壓力機(jī)設(shè)備的選定。關(guān)鍵詞關(guān)鍵詞:沖壓、模具、制造333目錄緒言..........
