蓋冒墊片落料拉深復(fù)合模設(shè)計(jì)說明書

1、摘要本次設(shè)計(jì)了一套沖孔，落料的模具。經(jīng)過查閱資料，首先要對零件進(jìn)行工藝分析，經(jīng)過工藝分析和對比，采用沖孔落料工序，通過沖裁力，頂件力，卸料力等的計(jì)算，確定壓力機(jī)的型號(hào)。在分析對沖壓件加工的模具適用類型選擇所需的模具。得出將設(shè)計(jì)的模具類型后將模具的各個(gè)工作零件部件的設(shè)計(jì)過程表達(dá)出來。在文檔中第一部分，主要敘述了沖壓模具的發(fā)展?fàn)顩r，說明了沖壓模具的重要性與本次設(shè)計(jì)的意義，接著是對沖壓件的工業(yè)分析，完成了材料利用率的計(jì)算。在進(jìn)行沖裁工藝力的計(jì)

2、算和沖裁模工作部分的設(shè)計(jì)計(jì)算，對選擇沖壓設(shè)備提供依據(jù)。最后是對主要零部件的選擇。本次設(shè)計(jì)闡述了沖壓落料復(fù)合模的結(jié)構(gòu)設(shè)計(jì)及工作過程。本模具性能可靠，運(yùn)行平穩(wěn)，提高了產(chǎn)品質(zhì)量和生產(chǎn)效率，降低勞動(dòng)強(qiáng)度和生產(chǎn)成本。關(guān)鍵字：沖壓：落料沖孔：復(fù)合模：模具結(jié)構(gòu)目錄1前言.............................................................11.1沖壓的概念、特點(diǎn)及應(yīng)用................
