15、eself the proportion to reach as high as about 60%, but the overseas mold ultra 70% is the commodity mold. The specialized mold factory mostly is "large and complete", "small and entire" organization

16、form, but overseas mostly is "small but", "is specially small and fine". Domestic large-scale, precise, complex, the long life mold accounts </p><p>  (3) The mold product level greatly i

63、/b></p><p>  模具是制造業(yè)的重要工藝基礎(chǔ),在我國(guó)模具制造屬于專(zhuān)用設(shè)備制造業(yè)。中國(guó)雖然很早就開(kāi)始制造模具和使用模具,但長(zhǎng)期未形成產(chǎn)業(yè)。直到20世紀(jì)80年代后期,中國(guó)模具工業(yè)才駛?cè)氚l(fā)展的快車(chē)道。近年,不僅國(guó)有模具企業(yè)有了很大發(fā)展,三資企業(yè)、鄉(xiāng)鎮(zhèn)(個(gè)體)模具企業(yè)的發(fā)展也相當(dāng)迅速。 雖然中國(guó)模具工業(yè)發(fā)展迅速,但與需求相比,顯然供不應(yīng)求,其主要缺口集中于精密、大型、復(fù)雜、長(zhǎng)壽命模具領(lǐng)域。由于在

64、模具精度、壽命、制造周期及生產(chǎn)能力等方面,中國(guó)與國(guó)際平均水平和發(fā)達(dá)國(guó)家仍有較大差距,因此,每年需要大量進(jìn)口模具。 中國(guó)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(jié)構(gòu)的調(diào)整和技術(shù)發(fā)展水平的提高。結(jié)構(gòu)調(diào)整方面,主要是企業(yè)結(jié)構(gòu)向?qū)I(yè)化調(diào)整,產(chǎn)品結(jié)構(gòu)向著中高檔模具發(fā)展,向進(jìn)出口結(jié)構(gòu)的改進(jìn),中高檔汽車(chē)覆蓋件模具成形分析及結(jié)構(gòu)改進(jìn)、多功能復(fù)合模具和復(fù)合加工及激光技術(shù)在模具設(shè)計(jì)制造上的應(yīng)用、高速切削、超精加工及拋光技術(shù)、信息化方

65、向發(fā)展。 近年,模具行業(yè)結(jié)構(gòu)調(diào)整和體制改革步伐加大,主要表現(xiàn)在,大型、精密、復(fù)雜、長(zhǎng)壽命、中高檔模具及模具標(biāo)準(zhǔn)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(zhuān)業(yè)模</p><p> ?。?)總量供不應(yīng)求,國(guó)內(nèi)模具自配率只有70%左右。其中低檔模具供過(guò)于求,中高檔模具自配率只有50%左右。 </p><p>  (2)企業(yè)組織結(jié)構(gòu)、產(chǎn)品結(jié)構(gòu)、技術(shù)結(jié)構(gòu)和進(jìn)出口結(jié)構(gòu)均不合理 。我

66、國(guó)模具生產(chǎn)廠(chǎng)中多數(shù)是自產(chǎn)自配的工模具車(chē)間(分廠(chǎng)),自產(chǎn)自配比例高達(dá)60%左右,而國(guó)外模具超過(guò)70%屬商品模具。專(zhuān)業(yè)模具廠(chǎng)大多是“大而全”、“小而全”的組織形式,而國(guó)外大多是“小而專(zhuān)”、“小而精”。國(guó)內(nèi)大型、精密、復(fù)雜、長(zhǎng)壽命的模具占總量比例不足30%,而國(guó)外在50%以上。2004年,模具進(jìn)出口之比為3.7:1,進(jìn)出口相抵后的凈進(jìn)口額達(dá)13.2億美元,為世界模具凈進(jìn)口量最大的國(guó)家。</p><p> ?。?)模具產(chǎn)

67、品水平大大低于國(guó)際水平,生產(chǎn)周期卻高于國(guó)際水平 產(chǎn)品水平低主要表現(xiàn)在模具的精度、型腔表面粗糙度、壽命及結(jié)構(gòu)等方面。 </p><p> ?。?)開(kāi)發(fā)能力較差,經(jīng)濟(jì)效益欠佳,我國(guó)模具企業(yè)技術(shù)人員比例低,水平較低,且不重視產(chǎn)品開(kāi)發(fā),在市場(chǎng)中經(jīng)常處于被動(dòng)地位。我國(guó)每個(gè)模具職工平均年創(chuàng)造產(chǎn)值約合1萬(wàn)美元,國(guó)外模具工業(yè)發(fā)達(dá)國(guó)家大多是15~20萬(wàn)美元,有的高達(dá)25~30萬(wàn)美元,與之相對(duì)的是我國(guó)相當(dāng)一部分模具企業(yè)還沿用過(guò)去作坊

68、式管理,真正實(shí)現(xiàn)現(xiàn)代化企業(yè)管理的企業(yè)較少。</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(zhǎng)期未得到應(yīng)有的重視,以及多數(shù)國(guó)有企業(yè)機(jī)制不能適應(yīng)市場(chǎng)經(jīng)濟(jì)之外,還有下列幾個(gè)原因: </p><p> ?。?)國(guó)家對(duì)模具工業(yè)的政策支持力度還不夠,雖然國(guó)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(guó)只有185家,大多數(shù)企業(yè)仍舊稅負(fù)過(guò)

69、重。模具企業(yè)進(jìn)行技術(shù)改造引進(jìn)設(shè)備要繳納相當(dāng)數(shù)量的稅金,影響技術(shù)進(jìn)步,而且民營(yíng)企業(yè)貸款十分困難。 </p><p> ?。?)人才嚴(yán)重不足,科研開(kāi)發(fā)及技術(shù)攻關(guān)投入太少,模具行業(yè)是技術(shù)、資金、勞動(dòng)密集的產(chǎn)業(yè),隨著時(shí)代的進(jìn)步和技術(shù)的發(fā)展,掌握并且熟練運(yùn)用新技術(shù)的人才異常短缺,高級(jí)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(duì)科研開(kāi)發(fā)和技術(shù)攻關(guān)重視不夠,科研單位和大專(zhuān)院校的眼睛盯著創(chuàng)收,導(dǎo)致模具行業(yè)在科研開(kāi)發(fā)

70、和技術(shù)攻關(guān)方面投入太少,致使模具技術(shù)發(fā)展步伐不大,進(jìn)展不快。 </p><p> ?。?)工藝裝備水平低,且配套性不好,利用率低,近年來(lái)我國(guó)機(jī)床行業(yè)進(jìn)步較快,已能提供比較成套的高精度加工設(shè)備,但與國(guó)外裝備相比,仍有較大差距。雖然國(guó)內(nèi)許多企業(yè)已引進(jìn)許多國(guó)外先進(jìn)設(shè)備,但總體的裝備水平比國(guó)外許多企業(yè)低很多。由于體制和資金等方面的原因,引進(jìn)設(shè)備不配套,設(shè)備與附件不配套現(xiàn)象十分普遍,設(shè)備利用率低的問(wèn)題長(zhǎng)期得不到較妥善的解決

71、。 </p><p>  (4)專(zhuān)業(yè)化、標(biāo)準(zhǔn)化、商品化程度低,協(xié)作能力差,由于長(zhǎng)期以來(lái)受“大而全”“小而全”影響,模具專(zhuān)業(yè)化水平低,專(zhuān)業(yè)分工不細(xì)致,商品化程度低。目前國(guó)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)模的模具成套任務(wù)。模具標(biāo)準(zhǔn)化水平低,模具標(biāo)準(zhǔn)件使用覆蓋率低也對(duì)模具質(zhì)量、成本有較大影響,特別是對(duì)模具制造周期有很大影響。 </p><

72、p> ?。?)模具材料及模具相關(guān)技術(shù)落后,模具材料性能、質(zhì)量和品種問(wèn)題往往會(huì)影響模具質(zhì)量、壽命及成本,國(guó)產(chǎn)模具鋼與國(guó)外進(jìn)口鋼材相比有較大差距。塑料、板材、設(shè)備性能差,也直接影響模具水平的提高。</p><p>  目前,我國(guó)經(jīng)濟(jì)仍處于高速發(fā)展階段,國(guó)際上經(jīng)濟(jì)全球化發(fā)展趨勢(shì)日趨明顯,這為我國(guó)模具工業(yè)高速發(fā)展提供了良好的條件和機(jī)遇。一方面,國(guó)內(nèi)模具市場(chǎng)將繼續(xù)高速發(fā)展,另一方面,模具制造也逐漸向我國(guó)轉(zhuǎn)移以及跨國(guó)集

73、團(tuán)到我國(guó)進(jìn)行模具采購(gòu)趨向也十分明顯。因此,放眼未來(lái),國(guó)際、國(guó)內(nèi)的模具市場(chǎng)總體發(fā)展趨勢(shì)前景看好,預(yù)計(jì)中國(guó)模具將在良好的市場(chǎng)環(huán)境下得到高速發(fā)展,我國(guó)不但會(huì)成為模具大國(guó),而且一定逐步向模具制造強(qiáng)國(guó)的行列邁進(jìn)?!笆晃濉逼陂g,中國(guó)模具工業(yè)水平不僅在量和質(zhì)的方面有很大提高,而且行業(yè)結(jié)構(gòu)、產(chǎn)品水平、開(kāi)發(fā)創(chuàng)新能力、企業(yè)的體制與機(jī)制以及技術(shù)進(jìn)步的方面也會(huì)取得較大發(fā)展。 模具技術(shù)集合了機(jī)械、電子、化學(xué)、光學(xué)、材料、計(jì)算機(jī)、精密監(jiān)測(cè)和信息網(wǎng)絡(luò)等諸

74、多學(xué)科,是一個(gè)綜合性多學(xué)科的系統(tǒng)工程。模具技術(shù)的發(fā)展趨勢(shì)主要是模具產(chǎn)品向著更大型、更精密、更復(fù)雜及更經(jīng)濟(jì)的方向發(fā)展,模具產(chǎn)品的技術(shù)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(wú)圖化、精細(xì)化、自動(dòng)化的方向發(fā)展,模具企業(yè)向著技術(shù)集成化、設(shè)備精良化、產(chǎn)批品牌化、管理信息化、經(jīng)營(yíng)國(guó)際化的方向發(fā)展。 </p><p>  模具行業(yè)在“十一五”期間需要解決的重點(diǎn)關(guān)鍵技術(shù)應(yīng)是模具信息化、數(shù)字化技術(shù)和精密、超精、高速

75、、高效制造技術(shù)方面的突破,隨著國(guó)民經(jīng)濟(jì)總量和工業(yè)產(chǎn)品技術(shù)的不斷發(fā)展,各行各業(yè)對(duì)模具的需求量越來(lái)越大,技術(shù)要求也越來(lái)越高。雖然模具種類(lèi)繁多,但其發(fā)展重點(diǎn)應(yīng)該是既能滿(mǎn)足大量需要,又有較高技術(shù)含量,特別是目前國(guó)內(nèi)尚不能自給,需大量進(jìn)口的模具和能代表發(fā)展方向的大型、精密、復(fù)雜、長(zhǎng)壽命模具。模具標(biāo)準(zhǔn)件的種類(lèi)、數(shù)量、水平、生產(chǎn)集中度等對(duì)整個(gè)模具行業(yè)的發(fā)展有重大影響。因此,一些重要的模具標(biāo)準(zhǔn)件也必須重點(diǎn)發(fā)展,而且其發(fā)展速度應(yīng)快于模具的發(fā)展速度,這樣才

76、能不斷提高我國(guó)模具標(biāo)準(zhǔn)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(guó)的模具產(chǎn)品在國(guó)際市場(chǎng)上占有較大的價(jià)格優(yōu)勢(shì),因此對(duì)于出口前景好的模具產(chǎn)品也應(yīng)作為重點(diǎn)來(lái)發(fā)展。根據(jù)上述需要量大、技術(shù)含量高、代表發(fā)展方向、出口前景好的原則選擇重點(diǎn)發(fā)展產(chǎn)品,而且所選產(chǎn)品必須目前已有一定技術(shù)基礎(chǔ),屬于有條件、有可能發(fā)展起來(lái)的產(chǎn)品。</p><p><b>  模具的發(fā)展趨勢(shì)</b></p>

79、;<p> ?。?)模具設(shè)計(jì)、分析及制造的三維化</p><p>  傳統(tǒng)的二維模具結(jié)構(gòu)設(shè)計(jì)已越來(lái)越不適應(yīng)現(xiàn)代化生產(chǎn)和集成化技術(shù)要求。模具設(shè)計(jì)、分析、制造的三維化、無(wú)紙化要求新一代模具軟件以立體的、直觀的感覺(jué)來(lái)設(shè)計(jì)模具,所采用的三維數(shù)字化模型能方便地用于產(chǎn)品結(jié)構(gòu)的CAE分析、模具可制造性評(píng)價(jià)和數(shù)控加工、成形過(guò)程模擬及信息的管理與共享。如Pro/ENGINEER、UG和CATIA等軟件具備參數(shù)化、基于

80、特征、全相關(guān)等特點(diǎn),從而使模具并行工程成為可能。另外,Cimatran公司的Moldexpert,Delcam公司的Ps-mold及日立造船的Space-E/mold均是3D專(zhuān)業(yè)注塑模設(shè)計(jì)軟件,可進(jìn)行交互式3D型腔、型芯設(shè)計(jì)、模架配置及典型結(jié)構(gòu)設(shè)計(jì)。澳大利亞Moldflow公司的三維真實(shí)感流動(dòng)模擬軟件MoldflowAdvisers已經(jīng)受到用戶(hù)廣泛的好評(píng)和應(yīng)用。國(guó)內(nèi)有華中理工大學(xué)研制的同類(lèi)軟件HSC3D4.5F及鄭州工業(yè)大學(xué)的Z-mol

81、d軟件。面向制造、基于知識(shí)的智能化功能是衡量模具軟件先進(jìn)性和實(shí)用性的重要標(biāo)志之一。如Cimatron公司的注塑模專(zhuān)家軟件能根據(jù)脫模方向自動(dòng)產(chǎn)生分型線(xiàn)和分型面,生成與制品相對(duì)應(yīng)的型芯和型腔,實(shí)現(xiàn)模架零件的全相關(guān),自動(dòng)產(chǎn)生材料明細(xì)表</p><p> ?。?)模具軟件應(yīng)用的網(wǎng)絡(luò)化趨勢(shì)</p><p>  隨著模具在企業(yè)競(jìng)爭(zhēng)、合作、生產(chǎn)和管理等方面的全球化、國(guó)際化,以及計(jì)算機(jī)軟硬件技術(shù)的迅速發(fā)展

82、,網(wǎng)絡(luò)使得在模具行業(yè)應(yīng)用虛擬設(shè)計(jì)、敏捷制造技術(shù)既有必要,也有可能。美國(guó)在其《21世紀(jì)制造企業(yè)戰(zhàn)略》中指出,到2006年要實(shí)現(xiàn)汽車(chē)工業(yè)敏捷生產(chǎn)/虛擬工程方案,使汽車(chē)開(kāi)發(fā)周期從40個(gè)月縮短到4個(gè)月。</p><p>  2. 模具檢測(cè)、加工設(shè)備向精密、高效和多功能方向發(fā)展</p><p> ?。?)模具檢測(cè)設(shè)備的日益精密、高效</p><p>  精密、復(fù)雜、大型模具的

83、發(fā)展,對(duì)檢測(cè)設(shè)備的要求越來(lái)越高?,F(xiàn)在精密模具的精度已達(dá)2~3μm,目前國(guó)內(nèi)廠(chǎng)家使用較多的有意大利、美國(guó)、日本等國(guó)的高精度三坐標(biāo)測(cè)量機(jī),并具有數(shù)字化掃描功能。如東風(fēng)汽車(chē)模具廠(chǎng)不僅擁有意大利產(chǎn)3250mm×3250mm三坐標(biāo)測(cè)量機(jī),還擁有數(shù)碼攝影光學(xué)掃描儀,率先在國(guó)內(nèi)采用數(shù)碼攝影、光學(xué)掃描作為空間三維信息的獲得手段,從而實(shí)現(xiàn)了從測(cè)量實(shí)物→建立數(shù)學(xué)模型→輸出工程圖紙→模具制造全過(guò)程,成功實(shí)現(xiàn)了逆向工程技術(shù)的開(kāi)發(fā)和應(yīng)用。這方面的設(shè)備還

84、包括:英國(guó)雷尼紹公司第二代高速掃描儀(CYCLON SERIES2)可實(shí)現(xiàn)激光測(cè)頭和接觸式測(cè)頭優(yōu)勢(shì)互補(bǔ),激光掃描精度為0.05mm,接觸式測(cè)頭掃描精度達(dá)0.02mm。另外德國(guó)GOM公司的ATOS便攜式掃描儀,日本羅蘭公司的PIX-30、PIX-4臺(tái)式掃描儀和英國(guó)泰勒?霍普森公司TALYSCAN150多傳感三維掃描儀分別具有高速化、廉價(jià)化和功能復(fù)合化等特點(diǎn)。</p><p> ?。?)數(shù)控電火花加工機(jī)床</p

86、 銑削加工是型腔模具加工的重要手段。而高速銑削具有工件溫升低、切削力小、加工平穩(wěn)、加工質(zhì)量好、加工效率高(為普通銑削加工的5~10倍)及可加工硬材料(<60HRC)等諸多優(yōu)點(diǎn)。因而在模具加工中日益受到重視。瑞士克朗公司UCP710型五軸聯(lián)動(dòng)加工中心,其機(jī)床定位精度可達(dá)8μm,自制的具有矢量閉環(huán)控制電主軸,最大轉(zhuǎn)速為42000r/min。意大利RAMBAUDI公司的高速銑床,其加工范圍達(dá)2500mm×5000mm×
