平高低的重要標記，并在很大程度上決定公司的生計空間。最近幾年很多冷沖模具公司加大了用于技術進步的投資力度，將技術進步視為公司發(fā)展的重要動力。一些國內(nèi)模具公司已普及了二維CAD，并陸續(xù)開始使用UG、Pro/Engineer、I-DEAS、Euclid-IS等國際通用軟件，個別廠家還引進了Moldflow、C-Flow、DYNAFORM、Optris和MAGMASOFT等CAE軟件，并成功應用于沖壓模的設計中。以汽車覆蓋件模具為代表的大型沖壓模具的制造技術已獲得很大進步，東風汽車公司模具廠、一汽模具中心等模具廠家已能生產(chǎn)部分轎車覆蓋件模具。別的，很多研究機構和大專院校展開模具技術的研究和開發(fā)。經(jīng)過多年的努力，在模具CAD/CAE/CAM技術方面取得了明顯進步；在提升模具質(zhì)量和縮短模具設計制造周期等方面做出了貢獻。固然中國冷沖模具工業(yè)在過去十多年中獲得了令人矚目的發(fā)展，但很多方面與工業(yè)發(fā)達國家對比仍有較大的差距。比如，精美加工設施在冷沖模具加工設施中的比重比較低；CAD/CAE/CAM技術的普及率不高；很多先進的模具技術應用不夠寬泛等等，以致相當一部分大型、精美、復雜和長壽命冷沖模具依靠入口。跟著科學技術的不停進步,現(xiàn)代工業(yè)產(chǎn)品的生產(chǎn)日趨復雜與多樣化,產(chǎn)品性能和質(zhì)量也在不停提升,因此對冷沖壓技術提出了更高的要求.為了使冷沖壓技術能適應各工業(yè)部門的需要,冷沖壓技術自己也在不停改革和發(fā)展.冷沖壓技術的發(fā)展思路就是盡可能地完善和擴大冷沖壓工藝的長處,戰(zhàn)勝其弊端.在冷沖壓技術的發(fā)展過程中,應注意以下幾方面：(1)冷沖壓技術的發(fā)展過程中應正確地確立工藝參數(shù)及冷沖模具工作部分的形狀與尺寸,提升沖壓件的質(zhì)量、縮短新產(chǎn)品試制周期,應在增強沖壓成形理論研究的基礎上,使沖壓成形理論達到能對生產(chǎn)實質(zhì)起指導作用,逐漸成立起一套親密聯(lián)合生產(chǎn)實質(zhì)的先進的工藝分析計算方法.外國已開始采納彈塑性有限元法對汽車覆蓋部件的成形過程進行應力應變分析和計算機模擬,以展望某一工藝方案對部件成形的可能性和可能出現(xiàn)的問題。加速產(chǎn)品更新?lián)Q代,戰(zhàn)勝模具設計周期長的弊端.應鼎力展開模具計算機協(xié)助設計和制造(CAD/CAM)技術的研究.在我國,當前要特別注意增強多工位級進模CAD/CAM技術的研究。知足大批生產(chǎn)需要以及減少勞動強度.應增強冷沖壓生產(chǎn)的機械化和自動化研究,使一般中、小件能在高速壓力機上采納多工位級進模生產(chǎn),達到生產(chǎn)高度自動化,進一步提升沖壓的生產(chǎn)率。擴大冷沖壓生產(chǎn)的運用范圍.使冷沖壓既合適大批生產(chǎn),也合適小批量生產(chǎn);既能生產(chǎn)一般精度的產(chǎn)品,也能生產(chǎn)精美部件.應注意開發(fā)如精美沖裁(特別是厚料精沖)、高能成形、軟模成形、施壓和超塑性加工等新成形工藝,還要推行簡略模(軟模和低熔點合金模)、通用組合模、數(shù)控沖床等設施的運用。別的,對沖壓板料性能的改良,模具新資料、模具新加工方法的開發(fā)也應進一步增強。四.冷沖模具使用壽命的影響及對策冷沖模具的使用壽命是以沖制出的工件數(shù)目來計算的。影響冷
