【正文】 request, the arrangement bination, pletes the many kinds of ramming working procedure when the identical inferior stroke the new craft equipment, the work the ramming unit not with the punch press slide joint, only needs the slide attack then to plete the ramming work. When independent employment it is 1 plete mold. It may use for to process the sheet or the molding punch holes, falls the material, cuts the angle, the grooving, shuts off and the shallow stretch and so on. Has the assembly strongly, the easy to operate, the versatility, the efficiency is quickly good and so on the characteristic, suits the multi varieties specially, center the production. may process the plastic in mold manufacture application May process the plastic to be mon in the developed industrial nation application, specially in manufacturing industry and so on automobile, airplane, mainly replaces the lumber or the metal manufacture automobile body host model, the profile, examines has and the casting model and so on. May process the plastic the main characteristic is has both the lumber and the metal fine workability, the manufacture craft simple and direct (may use pression molding, pour, spells sticks, method well and so on sculpture), the size stability, does not distort, bears moistly, anticorrosive, is easy to repair, the easy modification, the weight light, the manufacture cycle short, the cost to be low. Fast economical pattern making technology type very many, its has the characteristic, the application scope are various, this article only can broadly make some simple introductions, each kind of technology still had many concrete technological processes, the craft parameter and its the technical characteristic in the concrete application and the implementation 6 process. The mold is one of foundation industries, in the globalization market economy and under each kind of high technology and new technology swift and violent development situation, the fast economical mold has entrusted with the new mission and the brandnew connotation, the classification increases unceasingly, the fast economical pattern making material turns towards the multi varieties seriation to make great strides forward, the craft has the new innovation and the breakthrough unceasingly, is published one after another with it supplementary equipment, the service domain in opens up unceasingly, the creation economic efficiency is more and more remarkable. Along with the modity economy development, the intense market petition, the product renewal acceleration, is reducing the cycle to the fast economical pattern making technology, reduces the cost, will increase the precision and lengthens the life aspect the request to be able to be more and more high inevitably. Because it can cause the enterprise to win the market, creates the remarkable economic efficiency, more and more receives entrepreneur39。 RPM 是電腦、激光、光學(xué)掃描、先進(jìn)的新型材料、計(jì)算機(jī)輔助設(shè)計(jì) (CAD)、計(jì)算機(jī)輔助加工 (CAM)、數(shù)控 (CNC)綜合應(yīng)用的高新技術(shù)。 4 擠壓成型技術(shù) 利用鈹銅合金的良好的導(dǎo)熱性和穩(wěn)定性，經(jīng)固熔時(shí)效處理后，采用冷擠壓制造模具凹模型腔。彈壓力大小及受力點(diǎn) 位置可隨時(shí)、準(zhǔn)確、方便地調(diào)整，簡(jiǎn)化模具拉伸、壓邊、卸料等結(jié)構(gòu)，簡(jiǎn)化模 10 具設(shè)計(jì)，縮短制模周期，調(diào)試模具方便，縮短更換模具時(shí)間，提高生產(chǎn)效率。 模具是基礎(chǔ)工業(yè)之一， 在全球化市場(chǎng)經(jīng)濟(jì)和各種高新技術(shù)的迅猛發(fā)展形勢(shì)下，快速經(jīng)濟(jì)模具賦予了新的使命和全新的內(nèi)涵，分類不斷增加，快速經(jīng)濟(jì)制模材料向著多品種系列化邁進(jìn)，工藝不斷有新的創(chuàng)新和突破，與之配套設(shè)備相繼問世，服務(wù)領(lǐng)域在不斷地拓寬，創(chuàng)造的經(jīng)濟(jì)效益越來越顯著。具有組裝快捷、使用方便、通用性強(qiáng)、經(jīng)濟(jì)性好等 可加工塑料在模具制造中的應(yīng)用 可加工塑料在 發(fā)達(dá)的工業(yè)國(guó)家應(yīng)用較普遍，特別是在汽車、飛機(jī)等制造業(yè)中，主要代替木材或金屬制作汽車車身主模型、靠模、檢具和鑄造模型等。，可適合各種黑色和有色金屬的 厚的板料加工。 該技術(shù)的主要特點(diǎn)是時(shí)間短、費(fèi)用低，修補(bǔ)破損花紋圖案可做 到天衣無縫。 快速經(jīng)濟(jì)制模技術(shù)與傳統(tǒng)的機(jī)械加工相比，具有制模周期短、成本低、精度與壽命又能滿足生產(chǎn)上的使用要求，是綜合經(jīng)濟(jì)效益比較顯著的一類制造模具的技術(shù)，概括 1 快速原型制造技術(shù) 快速原型制造技術(shù)簡(jiǎn)稱 RPM，是 80年代后期發(fā)展起來的一種新型制造技術(shù)。s later period develops.
