該機組主要由轉(zhuǎn)臺（帶氣動驅(qū)動和定位機構(gòu)）、負(fù)壓分配閥、自動覆膜機、震實臺、自動雨淋式加砂機構(gòu)及貯砂斗等組成。轉(zhuǎn)臺上安放4臺造型模樣，兩組上箱，兩組下箱，分別由負(fù)壓箱、型板、模樣組合。轉(zhuǎn)臺由氣缸驅(qū)動并有兩個氣動定位銷確保轉(zhuǎn)臺定位無誤，負(fù)壓分配閥可根據(jù)各工位的抽真空要求自動抽氣，自動覆膜，是將成卷的薄膜放在托架上完成吸膜、輸送、烘烤、薄膜切斷、起箱覆膜功能。震實臺為平板式震實臺坐在四個空氣彈簧上，用振動電機激振，雨淋式加砂機構(gòu)由格子板、氣動插板閥控制加砂和關(guān)閉。整個動作程序由PLC程序控制。 </p> <p> 操作程序：Ⅰ工位：覆膜；Ⅱ工位：噴（刷）涂料，南通負(fù)壓V法鑄造裝備，放砂箱；Ⅲ工位：加砂震實；Ⅳ工位：蓋膜頂箱起模。如***工序為下箱時，則第二工序為上箱，上、下箱在平臺上合箱后，帶著真空負(fù)壓軟管一起吊運到澆注轉(zhuǎn)臺上。 </p> <p> 江陰華天科技開發(fā)有限公司為天津耐酸泵廠設(shè)計的四工位V法造型機屬于這種類型，主要生產(chǎn)耐酸泵葉輪等不銹鋼鑄件。年產(chǎn)量600～1000t/年，砂箱內(nèi)尺寸1000×630×150/150mm，南通負(fù)壓V法鑄造裝備，比較大砂箱尺寸1000×800×150/150mm，南通負(fù)壓V法鑄造裝備，造型生產(chǎn)率10～15型/h。根據(jù)涂料不同骨料組配的特性，合理地選擇V法鑄造用型砂。南通負(fù)壓V法鑄造裝備</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="南通負(fù)壓V法鑄造裝備,V法鑄造" src="https://tyunfile.71360.com/UploadFile/Jyhuatian/637293889370097657/738567.png"></div><p style="text-indent:25px">鑄型強度不夠或者不均勻，在有些具有大平面特點的鑄件生產(chǎn)上，不能很好的減小或防止鑄件在冷卻過程中的變形。有時候常常為了落砂的簡易性，對于下箱往往不加箱檔，以利于鑄件直接從砂箱脫出。這是不合理的。上下箱必須都設(shè)計抽氣箱檔，才能有效保障鑄型強度的均勻性及上下鑄型強度的對等性。圖9、圖10為某廠生產(chǎn)某種型號的鐵路側(cè)架鑄件的上下箱結(jié)構(gòu)圖。另外值得一提的是，砂箱結(jié)構(gòu)設(shè)計合理，對于同一套真空系統(tǒng)來講，可能同時允許接入的砂箱數(shù)量就會增加，意味著真空系統(tǒng)的利用效率明顯增強。南通負(fù)壓V法鑄造裝備涂料是保證鑄件表面質(zhì)量，防止粘砂的關(guān)鍵；</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="南通負(fù)壓V法鑄造裝備,V法鑄造" src="https://tyunfile.71360.com/UploadFile/Jyhuatian/637293889636621094/6553892.png"></div><p> 隨著V法鑄造向復(fù)雜結(jié)構(gòu)鑄件的延伸和拓展，原有的一維震實臺顯然已經(jīng)難以保障橫向縱深部位的填充緊實（見圖5），必須采用更為可靠的三維震實臺。但是部分企業(yè)始終意識不到這個問題，而因為這個問題而出現(xiàn)的粘砂或者尺寸失準(zhǔn)問題比比皆是。 </p> <p> <p> 起模機構(gòu)對鑄型質(zhì)量的影響 </p> <p> V法造型過程中，EVA薄膜與模具之間有一定的粘附力存在。再加上砂型的擠壓作用，使得起模過程中薄膜與模具之間存在明顯的摩擦。在提倡V法鑄造工藝少無拔模斜度的要求下，無疑對起模機構(gòu)的平穩(wěn)性有較為嚴(yán)格的要求。 </p> </p> <p> <br /> </p><p> 對于澆注系統(tǒng)的設(shè)計，不少文獻(xiàn)和資料均有詳盡解說，在此不再贅述，*就注意事項簡要說明。 </p> <p> 澆注系統(tǒng)盡量采用半開半閉方案，這種扼流型澆注系統(tǒng)可以有效避免高紊流狀態(tài)發(fā)生，可以降低金屬液在充型腔過程中的流動速度和對型壁、坭芯的沖擊，減少鑄造缺點。 </p> <p> 盡量采用陶瓷材料成型澆注系統(tǒng)，避免鋼水長時間沖刷澆道而造成由于夾砂、夾涂料產(chǎn)生的鑄造缺點。 </p> <p> 盡可能采用中間澆注方式，這樣可以減少因底注造成對上型壁長時間烘烤造成塌型、上型凹陷、薄膜和涂料產(chǎn)生的氣孔等，亦可減弱頂注產(chǎn)生對下型壁和坭芯的沖擊、紊流和裹氣等缺點。 </p> <p> 合理布置冒口，尤其是明冒口布置，一般應(yīng)布置在澆口附近和遠(yuǎn)離澆口的鑄件末端，便于透氣和排氣，易于鑄件成型和減少氣孔。利用高爐鐵水的熱量，大幅減少能源消耗，同時降污染物排放，節(jié)能，環(huán)保和經(jīng)濟效益。</p><div style="width:100%;text-align: center;"><img style="max-width:

江陰華天科技開發(fā)有限公司受用戶的委托設(shè)計并制造了一條汽車后橋半自動V法鑄造生產(chǎn)線。該生產(chǎn)線。 </p> <p> 本生產(chǎn)線采用4臺移動單機造型機組成的2臺V法造型機組，每臺機組的上、下箱分別在兩臺V法造型單機上完成。鑄型成形后用吊車將鑄型吊至合箱小車上進行修型、下芯、合箱，放置澆冒口杯，整體移至澆注工段進行澆注，冷卻凝固后鑄型連同型板吊至落砂格子板上落砂，舊砂經(jīng)砂冷卻后回用。 </p> <p> 汽車后橋材質(zhì)是鑄鋼；設(shè)計生產(chǎn)能力為10000t，實際生產(chǎn)能力為12000t；比較大鑄件質(zhì)量280kg；鑄型砂箱內(nèi)尺寸2000×1400×350/300mm；造型生產(chǎn)能力4-6型/h；砂處理能力20-25t/h；熔煉爐能力t電爐2臺。 </p> <p> <br /> </p> <p> 。 </p> <p> <br /> 鋁合金多采用開放式澆注系統(tǒng)F直∶F橫∶F內(nèi)＝1∶(2～3)∶(1～5)，**小截面積比砂型鑄造大20～30%；南通負(fù)壓V法鑄造裝備</p><p style="text-indent:25px">正確選擇真空泵以及合理的真空系統(tǒng)是保證V法鑄型穩(wěn)定負(fù)壓度的前提。南通負(fù)壓V法鑄造裝備</p><p style="text-indent:25px">這就是因為局部氣體難以迅速逃逸造成局部砂型強度下降的結(jié)果。有人提出低負(fù)壓大流量的說法，明確顯示出負(fù)壓很低但是整個生產(chǎn)過程非常安全。其實這就是砂箱結(jié)構(gòu)布置合理的效果。抽氣面積越大，抽氣位置越均勻越合理，泄入氣體排出越快，真空及鑄型強度穩(wěn)定性越好，塌箱危險性也越低；另有觀點認(rèn)為，只要整個鑄型處在一個負(fù)壓場下，各點的強度應(yīng)該是一樣的。實則不然。實踐表明，同一個鑄型，各點的強度是有差異的。如對于一個*有四壁抽氣的砂箱來說，鑄型的強度往往由砂箱四周向中心逐漸減弱的趨勢，而砂箱輪廓越大，這種趨勢越明顯。南通負(fù)壓V法鑄造裝備</p><p
