w 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。Modern fast economy manufacture mold technology Along with the global economy development, the new technological revolution made the new progress and the breakthrough unceasingly, the technical leap development already bees the important attribute which the impetus world economics grew. The market economy unceasing development, urges the industry product more and more to the multi varieties, high grade, the low cost direction to develop, in order to maintain and strengthens the product in market petitive power, product development cycle, production cycle more and more short, thereupon to makes each kind of product the essential craft equipment mold request to be more and more harsh. On the one hand the enterprise for the pursue scale benefit, causes the mold to turn towards high speed, is precise, the long life direction develops。單獨(dú)使用時(shí)它就是1副完整模具。 快速換模技術(shù) 7模具毛坯的快速制造技術(shù)—實(shí)型鑄造由于大量的模具是屬于單件或小批量生產(chǎn),模具毛坯的制造質(zhì)量和周期及成本對最終的模具質(zhì)量和周期及成本的影響是至關(guān)重要的。177。此項(xiàng)技術(shù)可以隨意改變變形路徑與受力狀態(tài),提高材料的成形極限,可反復(fù)成形,以此消除材料內(nèi)部的殘余應(yīng)力,實(shí)現(xiàn)無回彈成形。其特點(diǎn)是制造周期短,型腔精度高(IT7級),表面粗糙度Ra=,強(qiáng)度高,壽命可達(dá)50萬次,無環(huán)境污染。電弧噴涂成型制模技術(shù)快速原型制造技術(shù)簡稱RPM,是80年代后期發(fā)展起來的一種新型制造技術(shù)。一方面企業(yè)為追求規(guī)模效益,使得模具向著高速、精密、長壽命方向發(fā)展;另一方面企業(yè)為了滿足多品種、小批量、產(chǎn)品更新?lián)Q代快、贏得市場的需要,要求模具向著制造周期短、成本低的快速經(jīng)濟(jì)的方向發(fā)展。隨著全球經(jīng)濟(jì)的發(fā)展,新的技術(shù)革命不斷取得新的進(jìn)展和突破,技術(shù)的飛躍 發(fā)展已經(jīng)成為推動(dòng)世界經(jīng)濟(jì)增長的重要因素。它摒棄了傳統(tǒng)的機(jī)械加工方法,對制造業(yè)的變革是一個(gè)重大的突破,利用RPM技術(shù)可以直接或間接地快速制模,該技術(shù)已被汽車、航空、家電、船舶、醫(yī)療、模具等行業(yè)廣泛應(yīng)用。表面成型制模技術(shù),主要是利用噴涂、電鑄、化學(xué)腐蝕等新的工藝方法形成型腔表面及精細(xì)花紋的一種工藝技術(shù),實(shí)際應(yīng)用中包括以下幾種類型。目前該技術(shù)被廣泛地用于飛機(jī)、汽車的內(nèi)飾件模具、家電、家俱、制鞋、美術(shù)工藝品等表面形狀復(fù)雜及花紋精細(xì)的各種聚氨酯制品的吹塑、吸塑、PVC注射、PU發(fā)泡及各類注射成型模具中。 5無模多點(diǎn)成形技術(shù)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,簡化模具拉伸、壓邊、卸料等結(jié)構(gòu),簡化模具設(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。隨著商品經(jīng)濟(jì)的發(fā)展,激烈的市場競爭,產(chǎn)品更新?lián)Q代的加速,對快速經(jīng)濟(jì)制模技術(shù)在縮短周期、降低成本,提高精度和延長壽命方面的要求勢必會(huì)越來越高。s favor and the concerned leader department39。各種快速經(jīng)濟(jì)制模技術(shù)在推廣應(yīng)用過程中也會(huì)不斷完善成熟和發(fā)展,由于高新技術(shù)的發(fā)展,各種技術(shù)的復(fù)合與滲透,為適應(yīng)生產(chǎn)中的不同需求,今后必定會(huì)形成一些新型、節(jié)約能源、節(jié)約材料的快速制模技術(shù)。 可加工塑料在模具制造中的應(yīng)用沖壓單元組合技術(shù)是將常規(guī)的沖模分解為一個(gè)個(gè)簡單的單元沖模,根據(jù)工序件的要求,排列組合,在同一次沖程內(nèi)完成多種沖壓工序的新型工藝裝備,工作時(shí)沖壓單元不與沖床滑塊聯(lián)接,只需滑塊打擊即可完成沖壓工作。現(xiàn)代模具毛坯已廣泛地采用子實(shí)型鑄造技術(shù),所謂實(shí)型鑄造就是利用泡沫塑料(聚苯乙烯—PS或聚甲基丙烯酸酯—PMMA)制作代替?zhèn)鹘y(tǒng)的木模或金屬模,造型后不需取出模型,便可以澆鑄,泡沫塑料模型的高溫液體金屬作用下,迅速燃燒氣化而消失,金屬液取代原來泡沫塑料模型所占有的位置,冷凝后形成鑄件。這種模具重量輕,一般只有200kg,加工精度為無模多點(diǎn)快速成形技術(shù)是以CAD/CAM/CAT技術(shù)為主要手段,利用計(jì)算機(jī)控制高度可調(diào)基本體群形成上下成形面,代替?zhèn)鹘y(tǒng)模具對板料進(jìn)行三維曲面成形的又一現(xiàn)代先進(jìn)制造技術(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。型腔表面精細(xì)花紋成型的蝕刻技術(shù)蝕刻技術(shù)是光學(xué)、化學(xué)、機(jī)加工綜合應(yīng)用的一種技術(shù),它的基本原理是先把花紋圖案制成膠片,再把膠片上的花紋圖案復(fù)制在已涂上光敏材料的模具型腔表面上,經(jīng)過化學(xué)處理,模具型腔表面形成不被蝕刻部分的保護(hù)層,再根據(jù)模具材質(zhì),選擇相應(yīng)蝕刻工藝,將花紋圖案蝕刻在模具內(nèi)表面上。 1快速原型制造技術(shù)譯文:現(xiàn)代快速經(jīng)濟(jì)制造模具技術(shù)市場經(jīng)濟(jì)的不斷發(fā)展,促使工業(yè)產(chǎn) 品越來越向多品種、小批量、高質(zhì)量、低成本的方向發(fā)展,為了保持和加強(qiáng)產(chǎn)品在市場上的競爭力,產(chǎn)品的開發(fā)周期、生產(chǎn)周期越來越短,于是對制造各種產(chǎn)品的關(guān)鍵工藝裝備——模具的要求越來越苛刻。新型鋼帶沖裁落料制模技術(shù)是一種不同于一般具有凸、凹模結(jié)構(gòu)的鋼帶模,它是由單刃鋼帶與特制墊板組成的新型快速經(jīng)濟(jì)制模技術(shù)。 沖壓單元組合技術(shù)由于它能使企業(yè)贏得市場,創(chuàng)造顯著的經(jīng)濟(jì)效益,越來越受到企業(yè)家的青睞和有關(guān)領(lǐng)導(dǎo)部門的極大關(guān)注與政策資金的支持。s enormous attention and the policy fund support. Each kind of fast economical pattern making technology also can consummate mature and the development unceasingly in the promoted application process, as a result of the high technology and new technology development, each kind of technical bonding with the seepage, for the adaption production in different demand, surely will be able to form some, the frugal energy, the frugal material fast pattern making technology new from now on. 9 /
