（3）砂子處理：用過的砂子要經過除塵和冷卻方能使用。 </p> <p> 5．起膜并放置型芯 </p> <p> （1）起膜時要掌握行車，砂箱要平起，盡量避免錯位，錯位要及時修復。 </p> <p> （2）型芯為樹脂砂制作，表面涂油V法涂料。樹脂砂型芯較硬，能保證不粘砂和鑄件的完整。 </p> <p> （3）型芯的位置和尺寸要正確配合型腔 </p> <p> （4）型腔內的砂子用真空吸管抽走。 </p> <p> 6．修整型腔并合箱 </p> <p> （1）型腔的拐角、凸緣要補刷涂料以保證能夠鑄出完整。 </p> <p> （2）上線箱體之間放泥條來保證箱體之間的密封。 </p> <p> （3）合箱時要平起平落，不得與芯子相撞。 </p><p> 20世紀7o年代末我國有十余家企業(yè)引進了日本和德國V法鑄造設備和技術，提升了我國V法鑄造水平。據(jù)粗略統(tǒng)計，國內現(xiàn)有v法鑄造企業(yè)近200家，主要分布在山西、江蘇、安徽、山東和河北等地。江陰華天科技開發(fā)有限公司為青島四海電力鑄造廠設計一種固定式簡易V法造型機，它是鋼結構焊接而成，由底座支撐架、震實臺、負壓箱、頂箱機構等組成，具有結構新穎、外形美觀、運行可靠的特點。震實臺由四組頂桿同步，將砂箱平穩(wěn)地與模型分離。頂箱機的控制設有就地電控箱，人工操作，便于掌握起模時間。這種V法造型機機構簡單，更換模板方便，人工操作與機械化造型相結合，投資少，上馬快，比較適合單件、小批量鑄造車間使用，生產中、小型V法鑄件。面有所突破。 </p> <p> <br /> V法鑄造是設備﹑工藝和原輔材料相互配合協(xié)調平衡的有機結合，要全盤考慮協(xié)調的系統(tǒng)工程。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="南京真空密封V法鑄造,V法鑄造" src="https://tyunfile.71360.com/UploadFile/Jyhuatian/637293889370097657/738567.png"></div><p> <p> 砂處理設備 </p> <p> V法鑄造生產線的砂處理系統(tǒng)主要解決四個問題：一是去除舊砂中存在的鐵屑、鐵渣等雜物；二是去除舊砂斗中薄膜及砂芯的殘渣；三是落砂后的熱砂降溫至所需的溫度范圍；四是整個砂處理系統(tǒng)的除塵和吸塵保證舊砂的再生質量和環(huán)保的要求。一般V法所用砂含泥量低于0.3～0.5%之內。 </p> <p> 去除舊砂中的鐵性雜物一般采用貫通式或懸掛式永磁分選機。去除舊砂中的薄膜及砂芯等殘渣物，一般選用慣性直線振動篩和復合式篩分機。熱砂冷卻一般選用固定式流化床砂溫調節(jié)裝置或冷卻滾筒。除塵系統(tǒng)一般采用集中除塵，將落砂、篩分、冷卻、機運等揚塵點集中處理，選用旋風除塵器與袋式除塵組合式，均能達到良好的除塵效果。 </p> </p> <p> <br /> 縮短了生產鏈，省去了高爐鐵水凝固和重熔環(huán)節(jié)，簡稱為短流程鑄造工藝。南京真空密封V法鑄造</p><p style="text-indent:25px">真空密封造型是物理造型法，砂中無水分及其他輔料加入。南京真空密封V法鑄造</p><p style="text-indent:25px">V法鑄造用的砂箱，其結構形式直接決定著砂箱內負壓場的形成和分布，也就決定著鑄型強度的大小和均勻性。但是，不少觀念錯誤的認為，只要砂箱里面能夠抽氣就行，至于怎么抽，抽多少，都無關緊要，只要不塌箱即可。所以目前，既有單純的抽氣管抽氣的砂箱，也有靠四壁抽氣的砂箱，**復雜的則有四壁抽氣并外加箱帶或抽氣管輔助的形式；似乎都達到了同樣的目的，都能生產出鑄件。然而，產生的影響卻是不一樣的。生產上習慣了用真空度來衡量或者表征鑄型的強度，認為真空度越高，鑄型強度越高，塌箱的幾率也越小；實際上，對于砂箱來說，真空的形成是氣體流動的結果，是型腔內的空氣被真空系統(tǒng)抽走之后形成的。南京真空密封V法鑄造</p><p
