隨著制造行業(yè)的發(fā)展，材料加工方法也隨著發(fā)展，其中冷沖壓加工方法在制造行業(yè)得到了廣泛的發(fā)展，特別在汽車制造行業(yè)。隨著冷沖壓加工方法的應(yīng)用，許多汽車零件的外形和精度得到了改善。側(cè)減震片的加工方法也得到了發(fā)展，最后由冷沖壓加工而成。最近的幾年里，冷沖壓加工方法得到了廣泛的發(fā)展。 冷沖壓是建立在金屬塑性變形的基礎(chǔ)上，在常溫下利用安裝在壓力機(jī)上的模具對材料施加壓力，使其產(chǎn)生分離或塑性變形，從而獲得一定形狀、尺寸和性能的零件的一種加工方法。 在冷加工中，將材料（金屬或非金屬）加工成零件（或半成品）的一種特殊工藝裝備，稱為冷沖壓模具（俗稱冷沖模）。冷沖模在實現(xiàn)冷沖壓加工中是必不可少的工藝裝備，沒有先進(jìn)的模具技術(shù)，先進(jìn)的沖壓工藝就無法實現(xiàn)。隨著國民經(jīng)濟(jì)的高速發(fā)展、沖壓技術(shù)的發(fā)展和新型模具材料的不斷研究開發(fā)，市場對模具的需求量不斷增長，模具的結(jié)構(gòu)也發(fā)生了一定的變化，對模具的制造，裝配等都有了很大的影響。近年來，模具工業(yè)一直以15%左右的增長速度快速發(fā)展。模具是機(jī)械制造業(yè)中技術(shù)先進(jìn)、影響深遠(yuǎn)的重要工藝裝備,具有生產(chǎn)效率高、材料利用率高、制件質(zhì)量優(yōu)良、工藝適應(yīng)性好等特點,被廣泛應(yīng)用于汽車、機(jī)械、航天、航空、輕工、電子、電器、儀表等行業(yè)。 一、經(jīng)過幾十年的發(fā)展,沖壓模具行業(yè)獲得了飛速發(fā)展,具體體現(xiàn)在： (1)輔助設(shè)計/加工/工程技術(shù)得到廣泛使用。 (2)大型模具企業(yè)擁有高速數(shù)控加工/加工中心/數(shù)控機(jī)床等先進(jìn)的加工工藝與裝備,可以開展RP/RT或模具逆向工程工作,硬件裝備已經(jīng)站在了與世界基本同步的水平線上。 (3)在沖模的表面精整加工技術(shù)方面,開展了積極探索、積累了一些經(jīng)驗。 （4）以汽車覆蓋件為代表的大型、復(fù)雜、精密沖壓模具,采用CAD /CAM /CAE軟件進(jìn)行三維設(shè)計和模擬,減少試模時間和縮短周期。借助高速、精密的加工設(shè)備加工生產(chǎn),獲得良好的尺寸精度和表面粗糙度,用新型的研磨或拋光方法代替?zhèn)鹘y(tǒng)的手工研磨拋光,提高模具質(zhì)量。這些都代表了沖壓模具發(fā)展的趨勢。 二、國際模具制造業(yè)的技術(shù)特點如下： （1）產(chǎn)品專業(yè)化車身模具企業(yè)向?qū)I(yè)化發(fā)展，如德國大眾公司模具廠、奧迪公司模具廠、SCHULLER公司，意大利COMAU公司，美國AUTODIE、SECKLY，日本豐田公司模具廠、荻原公司、富士公司，韓國現(xiàn)代汽車模具中心等。有的專業(yè)制造整體側(cè)圍模具，有的專業(yè)生產(chǎn)四門模具，有的專門生產(chǎn)地板及結(jié)構(gòu)件模具。模具向多工位自動化以及級進(jìn)模方向發(fā)展。 （2）制造數(shù)字化三維實體設(shè)計廣泛應(yīng)用于模具制造中，二維DL圖轉(zhuǎn)為三維DL圖后可直接用于有限元分析和數(shù)控編程，百分之百采用CAE分析。模具設(shè)計采用3D參數(shù)化設(shè)計。實現(xiàn)了不等厚板成形模具設(shè)計，將同模模具推向生產(chǎn)。模具數(shù)控加工技術(shù)包括實型鑄造技術(shù)、精細(xì)化編程、高速加工技術(shù)、型面數(shù)控強(qiáng)化和修補(bǔ)技術(shù)。 三、沖壓模具制造技術(shù)發(fā)展趨勢： （1）制造沖壓件用的傳統(tǒng)金屬材料，正逐步被高強(qiáng)鋼板、涂敷鍍層鋼板、塑料夾層鋼板和其他復(fù)合材料或高分子材料替代。隨著材料科學(xué)的發(fā)展，加強(qiáng)研究各種新材料的沖壓成形性能，不斷發(fā)展和改善沖壓成形技術(shù)。 （2）精沖與半精沖、液壓成形、旋壓成形、爆炸成形、電水成形、電磁成形、超塑成形等技術(shù)得到不斷發(fā)展和應(yīng)用，某些傳統(tǒng)的沖壓加工方法將被它們所取代，產(chǎn)品的沖壓加工趨于更合理、更經(jīng)濟(jì)。其中精密沖裁技術(shù)得到了較快發(fā)展，精密沖裁是一種先進(jìn)制造技術(shù)，可取代某些零件的切削加工，具有優(yōu)質(zhì)、高效、低耗、應(yīng)用廣的特點。以齒圈壓板精沖而論，在普通液壓機(jī)上進(jìn)行精沖，工藝裝備簡單而工件精密。它以金屬板材為原料，采用少無切削的塑性加工方法，一次成形即可得到尺寸精度高、剪切面粗糙度低的零件，采用精沖技術(shù)生產(chǎn)的零件稱為精沖、件。 (3) 隨著計算機(jī)圖形技術(shù)的發(fā)展成熟，近年來在沖壓成形領(lǐng)域興起了計算機(jī)輔助設(shè)計(CAD)、計算機(jī)輔助工程(CAE)和計算機(jī)輔助制造(CAM)技術(shù)。該技術(shù)的出現(xiàn)對傳統(tǒng)沖壓技術(shù)的變革產(chǎn)生了重要的影響。尤其是板料成形數(shù)值模擬技術(shù)的出現(xiàn)，使板料沖壓成形技術(shù)徹底擺脫了“經(jīng)驗”和“定性”的水平，進(jìn)入了“科學(xué)”和“定量”的發(fā)展階段。采用這一技術(shù)進(jìn)行板材沖壓成形工藝過程的模擬，可以預(yù)知沖壓成形過程中金屬的流動、應(yīng)力應(yīng)變及厚度場的分布、模具受力及皺曲、破裂、沖擊線等可能的缺陷及失效形式。這為優(yōu)化工藝參數(shù)和模具結(jié)構(gòu)提供了極為有效的工具，在減少甚至取消試模過程，縮短產(chǎn)品開發(fā)周期，降低產(chǎn)品開發(fā)成本方面發(fā)揮著越來越重要的作用，已逐漸成為指導(dǎo)模具設(shè)計和優(yōu)化的重要手段。 (4)高速銑削加工，國內(nèi)外近年來發(fā)展的高速銑削加工，大幅度提高了加工效率，并可獲得極高的表面光潔度。另外，還可加工高硬度模塊，還具有溫升低、熱變形小等優(yōu)點。高速銑削加工技術(shù)的發(fā)展，對汽車、家電行業(yè)中大型型腔模具制造注入了新的活力。目前它已向更高的敏捷化、智能化、集成化方向發(fā)展。 (5)模具掃描及數(shù)字化系統(tǒng)，高速掃描機(jī)和模具掃描系統(tǒng)提供了從模型或?qū)嵨飹呙璧郊庸こ銎谕哪Ｐ退璧闹T多功能，大大縮短了模具的在研制制造周期。有些快速掃描系統(tǒng)，可快速安裝在已有的數(shù)控銑床及加工中心上，實現(xiàn)快速數(shù)據(jù)采集、自動生成各種不同數(shù)控系統(tǒng)的加工程序、不同格式的CAD數(shù)據(jù)，用于模具制造業(yè)的“逆向工程”。模具掃描系統(tǒng)已在汽車、摩托車、家電等行業(yè)得到成功應(yīng)用，相信在“十五”期間將發(fā)揮更大的作用。 (6)優(yōu)質(zhì)材料及先進(jìn)表面處理技術(shù)，選用優(yōu)質(zhì)鋼材和應(yīng)用相應(yīng)的表面處理技術(shù)來提高模具的壽命就顯得十分必要。模具熱處理和表面處理是否能充分發(fā)揮模具鋼材料性能的關(guān)鍵環(huán)節(jié)。模具熱處理的發(fā)展方向是采用真空熱處理。模具表面處理除完善應(yīng)發(fā)展工藝先進(jìn)的氣相沉積、等離子噴涂等技術(shù)。 四、沖壓在機(jī)械制造中的地位及特點： 沖壓既能夠制造尺寸很小的儀表零件，又能夠制造諸如汽車大梁、壓力容器封頭一類的大型零件；既能夠制造一般尺寸公差等級和形狀的零件，又能夠制造精密（公差在微米級）和復(fù)雜形狀的零件。占全世界鋼產(chǎn)60%～70%以上的板材、管材及其他型材，其中大部分經(jīng)過沖壓制成成品。沖壓在汽車、機(jī)械、家用電器、電機(jī)、儀表、航空航天、兵器等制造中，具有十分重要的地位。 沖壓件的重量輕、厚度薄、剛度好。它的尺寸公差是由模具保證的，所以質(zhì)量穩(wěn)定，一般不需再經(jīng)機(jī)械切削即可使用。冷沖壓件的金屬組織與力學(xué)性能優(yōu)于原始坯料，表面光滑美觀。冷沖壓件的公差等級和表面狀態(tài)優(yōu)于熱沖壓件[6]。 沖壓生產(chǎn)的工藝和設(shè)備正在不斷發(fā)展，除傳統(tǒng)的使用壓力機(jī)和鋼制模具制造沖壓件外，液壓成形以及旋壓成形、超塑成形、爆炸成形、電水成形、電磁成形等各種特種沖壓成形工藝亦迅速發(fā)展，把沖壓的技術(shù)水平提高到了一個新的高度。特種沖壓成形工藝尤其適合多品種的中小批量（甚至是數(shù)十件）零件的生產(chǎn)。對于普通沖壓工藝，可采用簡易模具、低熔點合金模具、成組模具和沖壓柔性制造系統(tǒng)等，組織多品種的中小批量零件的沖壓加工。 總之，沖壓模具具有生產(chǎn)率高、加工成本低、材料利用率高、操作簡單、便于實現(xiàn)機(jī)械化與自動化等一系列優(yōu)點。采用沖壓與焊接、膠接等復(fù)合工藝，使零件結(jié)構(gòu)更趨合理，加工更為方便，可以用較簡單的工藝制造出更復(fù)雜的結(jié)構(gòu)件。 附件2：外文原文 known as Die With the development of

(5) die scanning and digitizing system, high-speed scanners and mold scanning system provides a model or in kind from the scan to be processed into the desired model number of the necessary functions, greatly reducing the mold in the development of the manufacturing cycle. Some quick scan system, which can quickly installed in existing CNC milling machine and machining center, the fast data acquisition, automatic generation of a variety of CNC machining process, the CAD data in different formats for the mold manufacturing industry " Reverse Engineering. " Die scanning system has been in the automotive, motorcycle, household appliances and other industries has been successfully applied, I believe in the "Tenth Five-Year" period will play a greater role. ???? (6) high-quality materials and advanced surface treatment technologies, high-quality steel and application of the corresponding surface treatment technology to improve the life of mold it is very necessary. Mold heat treatment and surface treatment can give full play to the die steel material properties of the key link. Mold heat treatment is the development direction of vacuum heat treatment. In addition to improving the mold surface treatment technology should be developed advanced vapor deposition, plasma spraying techniques. Fourth, stamping machinery manufacturers in the position and characteristics: Pressing both capable of producing small-size instrument parts, but also capable of producing beams, such as automotive, pressure vessel head for a class of large parts; both capable of producing the general size and shape of the tolerance level of spare parts, also capable of producing precision (tolerances in the micron level ) and the complex shapes of parts. The world's steel production accounted for 60% ~ 70% of the plates, tubes and other profiles, most of which are made after stamping products. Stamping in the automotive, machinery, household appliances, electrical, instrumentation, aerospace, weapons manufacturing, a very important position. ????? Stamping parts of the light weight, thickness, stiffness good. Its size tolerance is guaranteed by the mold, so the quality of stability, in general no longer be used by mechanical cutting. Cold metal stampings and mechanical properties superior to the original blank, smooth surface appearance. Cold stamping tolerance level and surface state is superior to hot-stamping parts [6]. ????? Stamping production technology and equipment is growing, with the exception of the use of the traditional mold presses and steel stampings, the hydroforming and spinning forming, superplastic forming, explosive forming, electric water forming, electromagnetic forming a variety of special Stamping technology is also developing rapidly, the press raise the level of skills to a new height. Special metal forming process is particularly suitable for many species of small and medium-sized quantities (or even dozens of) parts production. For ordinary stamping process, to be used in simple mold, low melting point alloy die, die and stamping group flexible manufacturing systems, organizations and more species of small and medium-sized quantities of stamping parts processing. ????? In short, stamping die with high productivity, low processing costs, material utilization high, simple operation, easy to achieve mechanization and automation are a number of advantages. The use of stamping and welding, bonding and other composite process, so that more reasonable structural parts, processing more convenient, you can use relatively simple technology to create more complex structure.
