模具設計與制造外文翻譯

1、<p><b>　　模具設計與制造</b></p><p>　　模具是制造業(yè)的重要工藝基礎，在我國，模具制造屬于專用設備制造業(yè)。中國雖然很早就開始制造模具和使用模具，但長期未形成產(chǎn)業(yè)。直到20世紀80年代后期，中國模具工業(yè)才駛入發(fā)展的快車道。近年，不僅國有模具企業(yè)有了很大發(fā)展，三資企業(yè)、鄉(xiāng)鎮(zhèn)（個體）模具企業(yè)的發(fā)展也相當迅速。 </p><p>　　雖然中國模

2、具工業(yè)發(fā)展迅速，但與需求相比，顯然供不應求，其主要缺口集中于精密、大型、復雜、長壽命模具領域。由于在模具精度、壽命、制造周期及生產(chǎn)能力等方面，中國與國際平均水平和發(fā)達國家仍有較大差距，因此，每年需要大量進口模具。 </p><p>　　中國模具產(chǎn)業(yè)除了要繼續(xù)提高生產(chǎn)能力，今后更要著重于行業(yè)內(nèi)部結構的調(diào)整和技術發(fā)展水平的提高。結構調(diào)整方面，主要是企業(yè)結構向專業(yè)化調(diào)整，產(chǎn)品結構向著中高檔模具發(fā)展，向進出口結構的改進，

3、中高檔汽車覆蓋件模具成形分析及結構改進、多功能復合模具和復合加工及激光技術在模具設計制造上的應用、高速切削、超精加工及拋光技術、信息化方向發(fā)展。 </p><p>　　近年，模具行業(yè)結構調(diào)整和體制改革步伐加大，主要表現(xiàn)在，大型、精密、復雜、長壽命、中高檔模具及模具標準件發(fā)展速度高于一般模具產(chǎn)品；塑料模和壓鑄模比例增大；專業(yè)模具廠數(shù)量及其生產(chǎn)能力增加；“三資”及私營企業(yè)發(fā)展迅速；股份制改造步伐加快等。從地區(qū)分布來看

4、，以珠江三角洲和長江三角洲為中心的東南沿海地區(qū)發(fā)展快于中西部地區(qū)，南方的發(fā)展快于北方。目前發(fā)展最快、模具生產(chǎn)最為集中的省份是廣東和浙江，江蘇、上海、安徽和山東等地近幾年也有較大發(fā)展。 </p><p>　　雖然我國模具總量目前已達到相當規(guī)模，模具水平也有很大提高，但設計制造水平總體上落后于德、美、日、法、意等工業(yè)發(fā)達國家許多。當前存在的問題和差距主要表現(xiàn)在以下幾方面：</p><p>　　

5、（1）總量供不應求 </p><p>　　國內(nèi)模具自配率只有70%左右。其中低檔模具供過于求，中高檔模具自配率只有50%左右。 </p><p>　　（2）企業(yè)組織結構、產(chǎn)品結構、技術結構和進出口結構均不合理 </p><p>　　我國模具生產(chǎn)廠中多數(shù)是自產(chǎn)自配的工模具車間（分廠），自產(chǎn)自配比例高達60%左右，而國外模具超過70%屬商品模具。專業(yè)模具廠大多是“大而全

6、”、“小而全”的組織形式，而國外大多是“小而專”、“小而精”。國內(nèi)大型、精密、復雜、長壽命的模具占總量比例不足30%，而國外在50%以上。2004年，模具進出口之比為3.7:1，進出口相抵后的凈進口額達13.2億美元，為世界模具凈進口量最大的國家。</p><p>　?。?）模具產(chǎn)品水平大大低于國際水平，生產(chǎn)周期卻高于國際水平 </p><p>　　產(chǎn)品水平低主要表現(xiàn)在模具的精度、型腔表面

7、粗糙度、壽命及結構等方面。 </p><p>　?。?）開發(fā)能力較差，經(jīng)濟效益欠佳 </p><p>　　我國模具企業(yè)技術人員比例低，水平較低，且不重視產(chǎn)品開發(fā)，在市場中經(jīng)常處于被動地位。我國每個模具職工平均年創(chuàng)造產(chǎn)值約合1萬美元，國外模具工業(yè)發(fā)達國家大多是15～20萬美元，有的高達25～30萬美元，與之相對的是我國相當一部分模具企業(yè)還沿用過去作坊式管理，真正實現(xiàn)現(xiàn)代化企業(yè)管理的企業(yè)較少。

8、 </p><p>　　造成上述差距的原因很多，除了歷史上模具作為產(chǎn)品長期未得到應有的重視，以及多數(shù)國有企業(yè)機制不能適應市場經(jīng)濟之外，還有下列幾個原因： </p><p>　?。?）國家對模具工業(yè)的政策支持力度還不夠 </p><p>　　雖然國家已經(jīng)明確頒布了模具行業(yè)的產(chǎn)業(yè)政策，但配套政策少，執(zhí)行力度弱。目前享受模具產(chǎn)品增值稅的企業(yè)全國只有185家，大多數(shù)企業(yè)仍舊

9、稅負過重。模具企業(yè)進行技術改造引進設備要繳納相當數(shù)量的稅金，影響技術進步，而且民營企業(yè)貸款十分困難。 </p><p>　　（2）人才嚴重不足，科研開發(fā)及技術攻關投入太少 </p><p>　　模具行業(yè)是技術、資金、勞動密集的產(chǎn)業(yè)，隨著時代的進步和技術的發(fā)展，掌握并且熟練運用新技術的人才異常短缺，高級模具鉗工及企業(yè)管理人才也非常緊張。由于模具企業(yè)效益欠佳及對科研開發(fā)和技術攻關重視不夠，科研

10、單位和大專院校的眼睛盯著創(chuàng)收，導致模具行業(yè)在科研開發(fā)和技術攻關方面投入太少，致使模具技術發(fā)展步伐不大，進展不快。 </p><p>　?。?）工藝裝備水平低，且配套性不好，利用率低 </p><p>　　近年來我國機床行業(yè)進步較快，已能提供比較成套的高精度加工設備，但與國外裝備相比，仍有較大差距。雖然國內(nèi)許多企業(yè)已引進許多國外先進設備，但總體的裝備水平比國外許多企業(yè)低很多。由于體制和資金等

11、方面的原因，引進設備不配套，設備與附件不配套現(xiàn)象十分普遍，設備利用率低的問題長期得不到較妥善的解決。 </p><p>　?。?）專業(yè)化、標準化、商品化程度低，協(xié)作能力差 </p><p>　　由于長期以來受“大而全”“小而全”影響，模具專業(yè)化水平低，專業(yè)分工不細致，商品化程度低。目前國內(nèi)每年生產(chǎn)的模具，商品模具只占40%左右，其余為自產(chǎn)自用。模具企業(yè)之間協(xié)作不暢，難以完成較大規(guī)模的模具成

12、套任務。模具標準化水平低，模具標準件使用覆蓋率低也對模具質(zhì)量、成本有較大影響，特別是對模具制造周期有很大影響。 </p><p>　?。?）模具材料及模具相關技術落后 </p><p>　　模具材料性能、質(zhì)量和品種問題往往會影響模具質(zhì)量、壽命及成本，國產(chǎn)模具鋼與國外進口鋼材相比有較大差距。塑料、板材、設備性能差，也直接影響模具水平的提高。 </p><p>　　目

13、前，我國經(jīng)濟仍處于高速發(fā)展階段，國際上經(jīng)濟全球化發(fā)展趨勢日趨明顯，這為我國模具工業(yè)高速發(fā)展提供了良好的條件和機遇。一方面，國內(nèi)模具市場將繼續(xù)高速發(fā)展，另一方面，模具制造也逐漸向我國轉移以及跨國集團到我國進行模具采購趨向也十分明顯。因此，放眼未來，國際、國內(nèi)的模具市場總體發(fā)展趨勢前景看好，預計中國模具將在良好的市場環(huán)境下得到高速發(fā)展，我國不但會成為模具大國，而且一定逐步向模具制造強國的行列邁進。“十一五”期間，中國模具工業(yè)水平不僅在量和質(zhì)

14、的方面有很大提高，而且行業(yè)結構、產(chǎn)品水平、開發(fā)創(chuàng)新能力、企業(yè)的體制與機制以及技術進步的方面也會取得較大發(fā)展。 </p><p>　　模具技術集合了機械、電子、化學、光學、材料、計算機、精密監(jiān)測和信息網(wǎng)絡等諸多學科，是一個綜合性多學科的系統(tǒng)工程。模具技術的發(fā)展趨勢主要是模具產(chǎn)品向著更大型、更精密、更復雜及更經(jīng)濟的方向發(fā)展，模具產(chǎn)品的技術含量不斷提高，模具制造周期不斷縮短，模具生產(chǎn)朝著信息化、無圖化、精細化、自動化的

15、方向發(fā)展，模具企業(yè)向著技術集成化、設備精良化、產(chǎn)批品牌化、管理信息化、經(jīng)營國際化的方向發(fā)展。我國模具行業(yè)今后仍需提高的共性技術有： </p><p>　　（1）建立在CAD/CAE平臺上的先進模具設計技術，提高模具設計的現(xiàn)代化、信息化、智能化、標準化水平。 </p><p>　?。?）建立在CAM/CAPP基礎上的先進模具加工技術與先進制造技術相結合，提高模具加工的自動化水平與生產(chǎn)效率。

16、</p><p>　?。?）模具生產(chǎn)企業(yè)的信息化管理技術。例如PDM（產(chǎn)品數(shù)據(jù)管理）、ERP（企業(yè)資源管理）、MIS（模具制造管理信息系統(tǒng)）及INTERMET平臺等信息網(wǎng)絡技術的應用、推廣及發(fā)展。 </p><p>　?。?）高速、高精、復合模具加工技術的研究與應用。例如超精沖壓模具制造技術、精密塑料和壓鑄模具制造技術等。 </p><p>　?。?）提高模具生產(chǎn)效

17、率、降低成本和縮短模具生產(chǎn)周期的各種快速經(jīng)濟模具制造技術。 </p><p>　　（6）先進制造技術的應用。例如熱流道技術、氣輔技術、虛擬技術、納米技術、高速掃描技術、逆向工程、并行工程等技術在模具研究、開發(fā)、加工過程中的應用</p><p>　　（7）原材料在模具中成形的仿真技術。 </p><p>　　（8）先進的模具加工和專有設備的研究與開發(fā)。 </p&

18、gt;<p>　?。?）模具及模具標準件、重要輔件的標準化技術。 </p><p>　?。?0）模具及其制品的檢測技術。 </p><p>　?。?1）優(yōu)質(zhì)、新型模具材料的研究與開發(fā)及其正確應用。 </p><p>　?。?2）模具生產(chǎn)企業(yè)的現(xiàn)代化管理技術。 </p><p>　　模具行業(yè)在“十一五”期間需要解決的重點關鍵技術應

19、是模具信息化、數(shù)字化技術和精密、超精、高速、高效制造技術方面的突破。 </p><p>　　隨著國民經(jīng)濟總量和工業(yè)產(chǎn)品技術的不斷發(fā)展，各行各業(yè)對模具的需求量越來越大，技術要求也越來越高。雖然模具種類繁多，但其發(fā)展重點應該是既能滿足大量需要，又有較高技術含量，特別是目前國內(nèi)尚不能自給，需大量進口的模具和能代表發(fā)展方向的大型、精密、復雜、長壽命模具。模具標準件的種類、數(shù)量、水平、生產(chǎn)集中度等對整個模具行業(yè)的發(fā)展有重大

20、影響。因此，一些重要的模具標準件也必須重點發(fā)展，而且其發(fā)展速度應快于模具的發(fā)展速度，這樣才能不斷提高我國模具標準化水平，從而提高模具質(zhì)量，縮短模具生產(chǎn)周期，降低成本。由于我國的模具產(chǎn)品在國際市場上占有較大的價格優(yōu)勢，因此對于出口前景好的模具產(chǎn)品也應作為重點來發(fā)展。根據(jù)上述需要量大、技術含量高、代表發(fā)展方向、出口前景好的原則選擇重點發(fā)展產(chǎn)品，而且所選產(chǎn)品必須目前已有一定技術基礎，屬于有條件、有可能發(fā)展起來的產(chǎn)品。 </p>

21、<p>　　根據(jù)“十一五”模具行業(yè)發(fā)展規(guī)劃，“十一五”期間模具產(chǎn)品發(fā)展重點主要有如下幾類： </p><p>　?。?）汽車覆蓋件模具</p><p>　　沖壓模具占模具總量的40%以上。汽車覆蓋件模具主要為汽車配套，也包括為農(nóng)用車、工程機械和農(nóng)機配套的覆蓋件模具，它在沖壓模具中具有很大的代表性，模具大都是大中型，結構復雜，技術要求高。尤其是為轎車配套的覆蓋件模具，要求更高，可以

22、代表沖壓模具的水平。此類模具我國已有一定的技術基礎，已為中檔轎車配套，但水平還不高，能力不足，目前滿足率只有一半左右。中高檔轎車覆蓋件模具主要依靠進口，已成為汽車發(fā)展的瓶頸，極大的影響著車型開發(fā)。 </p><p>　?。?）精密沖壓模具 </p><p>　　多工位級進模和精沖模代表了沖壓模具的發(fā)展方向，精度要求壽命要求極高，主要為電子工業(yè)、汽車、儀器儀表、電機電器等配套。這兩種模具，國

23、內(nèi)已有相當基礎，并已引進了國外技術及設備，個別企業(yè)生產(chǎn)的產(chǎn)品已達到世界水平，但大部分企業(yè)仍有較大差距，供應總量不足，進口很多。 </p><p>　　（3）大型精密塑料模具 </p><p>　　塑料模具占模具總量近40%，而且這個比例還在上升。塑料模具中為汽車和家電配套的大型注塑模具，為集成電路配套的塑封模，為電子信息產(chǎn)業(yè)和機械及包裝配套的多層、多腔、多材質(zhì)、多色精密注塑模，為新型建材及

24、節(jié)水農(nóng)業(yè)配套的塑料異型材擠出模及管路和噴頭模具等，目前雖然已有相當技術基礎并正在快速發(fā)展，但技術水平與國外仍有較大差距，總量供不應求，每年的進口額達幾億美元。 </p><p>　?。?）主要模具標準件 </p><p>　　目前國內(nèi)已有較大產(chǎn)量的模具標準件主要是模架、導向件、推桿推管、彈性元件等。這些產(chǎn)品不但國內(nèi)配套大量需要，出口前景也很好，應繼續(xù)大力發(fā)展。氮氣缸和熱流道元件主要依靠進

25、口，應在現(xiàn)有基礎上提高水平，形成標準并組織規(guī)?；a(chǎn)。 </p><p>　?。?）其他高技術含量的模具 </p><p>　　占模具總量給8%的壓鑄模具中，大型薄壁精密壓鑄技術含量高，難度大。鎂合金壓鑄模具目前雖然剛起步，但發(fā)展前景好，有代表性。子午線橡膠輪胎模具也是發(fā)展方向，其中活絡模技術難度最大。與快速成型技術相結合的一些快速制模技術及相應的快速經(jīng)濟模具具有很好的發(fā)展前景。這些高技術

26、含量的模具在“十一五”期間也應重點發(fā)展。</p><p><b>　　附件2：外文原文</b></p><p>　　Mold design and manufacture</p><p>　　The mold is the manufacturing industry important craft foundation, in our cou
