style="text-indent:25px">V法鑄造是真空密封造型或負壓造型鑄造工藝的簡稱，其原理是利用塑料薄膜覆模造型并密封砂箱，依靠真空泵抽出型內(nèi)空氣，造成型內(nèi)箱外壓力差，使干砂緊實，形成所需型腔。其比較大優(yōu)勢是型砂不使用粘結劑，干砂回用率高達95%以上，南京V法鑄造原理，不*節(jié)能環(huán)保、落砂簡便、改善勞動條件，而且鑄件表面品質和尺寸精度**提高。V法鑄造是日本長野縣工業(yè)試驗所和秋田株式會社于1971年的發(fā)明專利。V法鑄造至今經(jīng)過了38年的發(fā)展，同消失模鑄造一樣，南京V法鑄造原理，作為第3代造型方法即物理硬化方法，在世界上尤其是在中國獲得了長足的發(fā)展。近國內(nèi)消失模生產(chǎn)廠家發(fā)展迅速，南京V法鑄造原理，尤其是中小廠家，但實踐中有些鑄件采用消失模鑄造不很對號。南京V法鑄造原理</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="南京V法鑄造原理,V法鑄造" src="https://tyunfile.71360.com/UploadFile/Jyhuatian/637293889644755860/7471982.png"></div><p> V法鑄造投資少，砂處理系統(tǒng)較為簡單，運行能耗少。 </p> <p> 與其他砂型鑄造相比，V法鑄造環(huán)境友好，生產(chǎn)現(xiàn)場噪音低，鑄件拋丸清理量減少50%以上，勞動力減少35%以上。澆注時，薄膜、涂料和樹脂砂芯產(chǎn)生的煙氣都被真空系統(tǒng)抽走，經(jīng)過干濕過濾后排空，對大氣污染少；V法固體廢棄物少，干砂再生高達95％。符合節(jié)能減排的高要求。 </p> <p> V法優(yōu)勢鮮明，其弊端也很突出： </p> <p> 受到薄膜延伸性能的局限，V法鑄造不適宜生產(chǎn)外形復雜鑄件； </p> <p> V法制芯技術還不成熟，采用樹脂砂芯或水玻璃砂芯才能鑄造內(nèi)腔復雜鑄件； </p> <p> 真空系統(tǒng)需隨時與砂型相連； </p> <p> V法鑄造不適合生產(chǎn)小型鑄件，生產(chǎn)效率難以提高； </p> <p> V法鑄鋼易出現(xiàn)氣孔和夾渣等鑄造缺點，尤其低碳鋼件有較嚴重的增碳。南京覆膜砂V法鑄造工藝干砂造型抽真空后減小了砂與砂之間的間隙，增加了砂與砂之間的摩擦力，提高砂強度。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="南京V法鑄造原理,V法鑄造" src="https://tyunfile.71360.com/UploadFile/Jyhuatian/637293889813476563/989149.png"></div><p> 重視系統(tǒng)化工程的設計 </p> <p> 耐磨鑄造車間的建設是一個系統(tǒng)工程，除了生產(chǎn)設備本身外，車間布局物流設計，原輔材料的配套，熱處理系統(tǒng)的配套，機加工設備的配套等都要作為系統(tǒng)的一部分考慮。 </p> <p> 以砂箱的周轉為例，耐磨鑄件由于保溫冷卻時間長，在一定程度上限制了砂箱的流轉速度，企業(yè)訂購大量砂箱不***增加了企業(yè)成本，而且造成管理使用上的困難。可通過采用建設冷卻立體庫，設計冷卻托盤的方式加快砂箱流轉，同時節(jié)約生產(chǎn)場地。標準化托盤的設計和制作，滿足叉車運輸條件，并不額外增加過多的勞動力，實現(xiàn)了工藝生產(chǎn)的要求，降低了設備投資成本，同時提高的系統(tǒng)運行效率。 </p><p> 四工位轉臺式V法造型機 </p> <p> 該機組主要由轉臺（帶氣動驅動和定位機構）、負壓分配閥、自動覆膜機、震實臺、自動雨淋式加砂機構及貯砂斗等組成。轉臺上安放4臺造型模樣，兩組上箱，兩組下箱，分別由負壓箱、型板、模樣組合。轉臺由氣缸驅動并有兩個氣動定位銷確保轉臺定位無誤，負壓分配閥可根據(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，雨淋式加砂機構由格子板、氣動插板閥控制加砂和關閉。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，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，帶著真空負壓軟管一起吊運到澆注轉臺上。 </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，比較大砂箱尺寸1000×800×150/150mm，造型生產(chǎn)率10～15型/h。砂子的回收率很高可達95%以上，動力消耗*為濕法造型的60%，并可減少勞動力35%。</p><div

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，一般應布置在澆口附近和遠離澆口的鑄件末端，便于透氣和排氣，易于鑄件成型和減少氣孔。合理的澆注系統(tǒng)及澆注速度是防止產(chǎn)生脹砂、塌箱、增厚等缺點的關鍵措施；南京優(yōu)良V法鑄造設備</p><p
