摘 要
沖壓是在室溫下，利用安裝在壓力機上的模具對材料施加壓力，使其產(chǎn)生分離或塑性變形，從而獲得所需零件的加工方法。沖壓通常是在常溫下對材料進行冷變形加工，且主要采用板料來加工成所需零件，所以也叫冷沖壓或板料沖壓。沖壓是材料壓力加工或塑性加工的主要方法之一，是一種材料成形工程技術(shù)。在沖壓加工中，將材料（金屬或非金屬）加工成零件（或半成品）的一種特 殊工藝設(shè)備，稱為沖壓模具（簡稱沖模）。沖模在實現(xiàn)沖壓加工中是必不可少的工藝裝備，與沖壓件是“一模一樣”的關(guān)系，若沒有符合要求的沖模，就不可能生產(chǎn)出合格的沖壓件;沒有先進的沖模，先進的沖壓成形工藝就無法實現(xiàn)。在沖壓零件的生產(chǎn)中合理的沖壓成形工藝、先進的模具、高效的沖壓設(shè)備是 必不可少的三要素。本設(shè)計主要介紹鏈條連接件落料沖孔沖壓倒裝式復合模。本設(shè)計主要包括沖裁件的工藝性分析、沖裁件沖壓工藝方案和模具結(jié)構(gòu)形式的確定、沖裁件的排樣和利用率、沖壓總力計算和模具壓力中心的確定、工作零件刃口尺寸計算、工作零件結(jié)構(gòu)設(shè)計、其他零部件設(shè)計、模具閉和高度的計算、沖壓設(shè)備的選擇、零件圖和裝配圖的繪制和模具的試模和調(diào)試等。另外，還附有畢業(yè)設(shè)計任務(wù)書、部分模具零件沖壓工藝過程卡以及模具結(jié)構(gòu)工序卡、零件沖壓工藝卡、裝配圖和零件圖。
