style="text-indent:25px">冷沖壓或板料沖壓是使金屬板料在沖模中承受壓力而被切離或成形的加工方法。日常生活用品，女口鋁鍋、飯盒、臉盆等就是采用冷沖壓的加工方法制成。例如制造飯盒，首先需要切出長方形并帶有4個圓角的坯料(行家稱為“落料”)，然后用凸模將這塊坯料壓入凹模而成形(行家稱為“拉深”)。在拉深工序，平面的板料變?yōu)楹袪睿?邊向上垂直彎曲，4個拐角的材料產(chǎn)生堆聚并可看到皺褶。采用冷沖壓加工的汽車零件有：發(fā)動機(jī)油底殼，制動器底板，汽車車架以及大多數(shù)車身零件。這些零件一般都經(jīng)過落料、沖孔、拉深、彎曲、翻邊、修整等工序而成形。為了制造冷沖壓零件，必須制備沖模。沖模通常分為2塊，其中一塊安裝在壓床上方并可上下滑動，另一塊安裝在壓床下方并固定不動。生產(chǎn)時，坯料放在2塊沖模之間，當(dāng)上下模合攏時，沖壓工序就完成了。沖壓加工的生產(chǎn)率很高，并可制造形狀復(fù)雜而且精度較高的零件。</p><p style="text-indent:25px">汽車白車身零件95%（重量）以上是沖壓件，在沖壓件結(jié)構(gòu)設(shè)計確定后，應(yīng)充分考慮其加工的經(jīng)濟(jì)性，比較大程度降低沖壓件成本。沖壓件成本通常包括毛坯板料費(fèi)、沖次費(fèi)、模具工裝攤銷費(fèi)等。在多數(shù)工廠里，設(shè)備、人員、材料等外界條件在一定時期內(nèi)基本不變，而要降低沖壓件成本，主要從沖壓工藝的合理排布方面著手。汽車白車身用沖壓零件的長度一般在3m以內(nèi)，而白車身60%（重量）以上的零件長度主要集中在1m左右（上下波動0.3m），這部分零件通常被稱為中型件，一般為車身骨架的主要組成部分。汽車壓縮模又稱壓制?；驂耗z模。</p><div

style="text-indent:25px">現(xiàn)在我們這個板塊一說汽車模具好像都指的是汽車覆蓋件沖模。為了不和廣義的汽車沖模混淆，在發(fā)帖時比較好用汽車覆蓋件沖模不用汽車沖模。汽車輪胎模具用于硫化成型各類輪胎的模具。汽車輪胎模具分類 1：活絡(luò)模具，由花紋圈，模套，上下側(cè)板組成。活絡(luò)模具區(qū)分圓錐面導(dǎo)向活絡(luò)模具及斜平面導(dǎo)向活絡(luò)模具 2：兩半模具，由上模，下模兩片組成。汽車輪胎模具加工工藝以活絡(luò)模具為例 1：根據(jù)輪胎模具圖鑄造或鍛打毛坯，再粗車毛坯并熱處理。輪胎模具毛坯進(jìn)行完全退火處理，消除內(nèi)應(yīng)力，退火時應(yīng)放平，避免變形過大。汽車沖壓模具是沖制汽車上所有沖壓件的模具。啟東汽車車身模具</p><p

style="text-indent:25px">在模具工法和結(jié)構(gòu)設(shè)計時，根據(jù)沖壓件的難易程度，考慮選擇采用拉延工藝還是落料成形工藝，采用拉延工藝的產(chǎn)品質(zhì)量更優(yōu)，調(diào)試時間更短，而采用落料成形工藝，材料利用率更高，模具結(jié)構(gòu)更簡單，成本更低。從降低模具成本考慮，建議考慮落料成形工藝。在模具工法和結(jié)構(gòu)設(shè)計時，針對手工線生產(chǎn)的模具，可以采用諸如空手槽取代氣動頂出裝置等方式節(jié)省模具成本，而部分中小批量的車型進(jìn)行模具設(shè)計時，建議從50萬沖次的模具使用壽命變更為30萬沖次的模具使用壽命，從而選擇對應(yīng)沖次的模具制造材料，適當(dāng)減小壁厚，降低成本。啟東汽車模具制造企業(yè)</p></p><br
