【正文】 design model can be based on the establishment of automated processing, you can also automatically detect the end of processing. third Development Trend of Die Manufacturing Technology As China continues to develop the socialist market economy, increasing the variety of industrial products, product upgrading accelerated an increasingly petitive market. Therefore, improving the quality of the mold and shorten the production cycle is particularly important to promote mold The following trends in technology development. 1. Roughing mold technology to the development of high speed machining. Represented by highspeed milling technology represents a highspeed machining Rough surface of mold shape the direction of development. Highspeed milling can greatly improve the quality of the mold surface, and large greatly improve processing efficiency and reduce processing costs. 汽車沖壓件工藝與模具設(shè)計 第 42 頁 共 46 頁 Highspeed machining center cutting feed rate of up to 76m/min, Spindle Scooter 45000r/min. In addition, the rough cutting device has highspeed sawing, cutting and laser cutting the anode highspeed,highefficiency processing equipment, there has been a strong highspeed grinding equipment and grinding equipment. 2. Forming the surface of the processing to sophisticated, automated direction. Forming the surface of the processing to the puter control and high precision degree of processing direction. CNC machining centers, CNC EDM equipment, putercontrolled continuous path coordinate grinding bed and dressing assembly with CNC forming and precision measuring devices such as grinding equipment to promote the use, the system is to improve the mold the key to making technology. 3. Finishing technology to automate direction. The current die forming surface grinding, polishing and other processing operations are still mainly by hand, not only to spend hours more, and laborintensive, low surface quality. Industrial countries are being developed by the puter control, autofill with abrasive wear pensation device finishing equipment, can be plex threedimensional surface for surface finishing, and began to mold the use, greatly improving the finishing quality and efficiency. 4. Reverse mold manufacturing engineering technology. To coordinate measuring machines and rapid prototyping technology as the representative of the reverse manufacturing technology, is a kind of copy for the principle of manufacturing has a significant impact. This technology is particularly suitable for multispecies, smallvolume, plex shape of the mold manufacturing, on reduce the die manufacturing cycle, and to improve the market petitiveness of products is important. 5. Die CAD / CAM technology will have a faster development. Die CAD / CAM technology in mold design and manufacturing advantages more and more obvious, it is another mold technology revolution, universal and improve CAD / CAM technology is a manufacturing mold inevitable trend of development. 汽車沖壓件工藝與模具設(shè)計 第 43 頁 共 46 頁 為你提供優(yōu)秀的畢業(yè)論文參考資料,請 您刪除以下內(nèi)容, O(∩_∩)O 謝謝?。?! 2 Many people have the same mixed feelings when planning a trip during Golden Week. With heaps of time, the sevenday Chinese為你提供優(yōu)秀的畢業(yè)論文設(shè)計參考資料,請您刪除一下內(nèi)容, O(∩_∩)O謝謝!?。?National Day holiday could be the best occasion to enjoy a destination. However, it can also be the easiest way to ruin how you feel about a place and you may bee more fatigued after th。s mold industry, the state has taken a number of specific measures, such as a professional mold factory investment transformation into the capital, will die as a key scientific and technological projects of national planning, engineering and technical personnel sent abroad on test observation, the introduction of foreign advanced technology mold to develop standards related to the mold. In recent years, rapid development of China39。 Die Manufacturing Technology Status and Development First Status of China Die Manufacturing Technology In modern industrial production, the mold is one of the important technology and equipment. With the development of science and technology, industrial products Variety and increasing number of modified products to accelerate new generation of product quality and appearance have made new demands on quality requirements of the mold growing. Mold design and manufacturing level of direct impact on national economic development, the world39。 5.模具 CAD/CAM 技術(shù)將有更快的發(fā)展。 以三坐標(biāo)測量機和快速成型制造技術(shù)為代表的逆向制造技術(shù),是一種以復(fù)制為原理 的制造具有重大的影響。工業(yè)發(fā)達國家正在研制由計算機控制、帶有磨料磨損自動補 償裝置的光整加工設(shè)備,可 以對復(fù)雜型面的三維曲面進行光整加工,并開始在模具加工上 使用,大大提高了光整加工的質(zhì)量和效益。 。 成型表面的加工向計算機控制和高精度加工方向發(fā)展。另外,毛坯下料設(shè)備出現(xiàn)了高速鋸床、陽極切割和激光切割等高速、高效率 加工設(shè)備,出現(xiàn)了高速磨削設(shè)備和強力磨削設(shè)備。高速銑削可以大大改善模具表面的質(zhì)量狀況,并大大提高加工效率和降低加工成本。 1. 模具粗加工技術(shù)向高速加工發(fā)展。 三 模具制造技術(shù)的發(fā)展趨勢 隨著我國社會主義市場經(jīng)濟的不斷發(fā)展,工業(yè)產(chǎn)品的品種增多,產(chǎn)品更新?lián)Q代加快, 市場競爭日益激烈。 隨著計算機技術(shù)的發(fā)展應(yīng)用,計算機輔助模具設(shè)計與制造( CAD/CAM)趨于成熟,模具設(shè)計與制造一體化技術(shù)已經(jīng)實現(xiàn)。商品化推動了專業(yè)化生產(chǎn),降低了制造成本,縮短了制造周期,提高了標(biāo)準(zhǔn)件的內(nèi)外部質(zhì)量,也促進了新型材料的應(yīng)用。到目前為止,已經(jīng)制定了沖壓模具、塑料模具、壓鑄模具和模具基礎(chǔ)技術(shù)等 50 多項國家標(biāo)準(zhǔn),近 300 多個標(biāo)準(zhǔn)號,基本滿足了國內(nèi)模具生產(chǎn)技術(shù)發(fā)展的需要。 。 。 二 模具制造技術(shù)隨著制造業(yè)技術(shù)的發(fā)展而發(fā)展的狀況 1. 模具制造技術(shù)隨著制造設(shè)備水平的提高而提高。凹模鑲件的重復(fù)定位精度 ,步距精度 ,模具 成形表面粗糙度達到 m。近幾年我國的模具工業(yè)發(fā)展較快, 模具制造水平也在逐步提高。但總體還存在著制造的模具品種少、精度差、壽命短、生產(chǎn)周期長的弊端,精密、 復(fù)雜、大型模具很多因為國內(nèi)制造困難,也不得不從國外進口。 目前,我國的模具行業(yè)生產(chǎn)廠家數(shù)千個,職工有 50 萬人,每年能生產(chǎn)百萬套模具。模具設(shè)計與制造水平的高低,直接影響著國民經(jīng)濟的發(fā)展, 世界上工業(yè)發(fā)達的國家,模具工業(yè)發(fā)展迅速,模具總產(chǎn)值超過機床工業(yè)的總產(chǎn)值,發(fā)展 速度超過了機床、汽車、電子等工業(yè),是國民經(jīng)濟的基礎(chǔ) 工業(yè)之一。北京:機械工業(yè)出版, 2022. 汽車沖壓件工藝與模具設(shè)計 第 38 頁 共 46 頁 附:中英文翻譯 模具 制造技術(shù) 的現(xiàn)狀與發(fā)展 一 我國模具制造技術(shù)的現(xiàn)狀 在現(xiàn)代工業(yè)生產(chǎn)中,模具是重要的工藝裝備之一。 9. 王堯培。上海三住精密機械有限公司, 2022. 7. 中國機械工程會,中國機械設(shè)計大典編委會,中國機械設(shè)計大典:第 2 卷,機械設(shè)計基礎(chǔ)。 6. 上海三住精密機械有限公司。 5. 全國模具標(biāo)準(zhǔn)化技術(shù)委員會,桂林電器科學(xué)研究所, ISO 模具標(biāo)準(zhǔn)匯編。中國機械工業(yè)標(biāo)準(zhǔn)匯編:沖壓模具卷,上,北京:中國標(biāo)準(zhǔn)出版社, 1998. 4. 許發(fā)樾主編,模具標(biāo)準(zhǔn)應(yīng)用手冊。高等教育出版社, 2022。 汽車沖壓件工藝與模具設(shè)計 第 37 頁 共 46 頁 參考文獻 1. 成虹總而言之,學(xué)到了很多知識。 設(shè)計兩套模具確實 不是一件容易的事情,期間碰到各種各樣的難題,非常感謝王黛雯老師的指導(dǎo),才使設(shè)計能夠一步一步進行下去。在設(shè)計過程中要考慮工件定位的問題,若定位不確定,就不能加
