江陰華天科技開發(fā)有限公司受用戶的委托設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，南通負壓V法鑄造企業(yè)。 </p> <p> <br /> </p> <p> 。 </p> <p>

style="text-indent:25px">目前，大部分廠家已經(jīng)采用頂桿起模機（見圖6），甚至自動化程度更高的機械手完成起模動作（見圖7）。相比之前的行車起模和簡單的千斤頂起模方式來說，起模的安全性和穩(wěn)定性已經(jīng)有了很大進步。但是，在越來越多精密鑄件成形的過程中，逐漸發(fā)現(xiàn)部分起模頂桿或者機械手的精度和強度問題。主要反映在起模頂桿導柱導套所用材質(zhì)的質(zhì)量和數(shù)量不夠達標，或者不經(jīng)過應有的熱處理工藝，造型起模頂桿強度和剛性不足。再加上加工或安裝精度不夠，造成起模過程中頂桿的撓曲變形和起模不穩(wěn)，致使鑄型部分位置擦傷破損，影響鑄型完整性，造成鑄件粘砂，甚至塌箱等缺點。南通覆膜砂V法鑄造生產(chǎn)線V法鑄造是設備﹑工藝和原輔材料相互配合協(xié)調(diào)平衡的有機結(jié)合，要全盤考慮協(xié)調(diào)的系統(tǒng)工程。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="南通負壓V法鑄造企業(yè),V法鑄造"

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。</p><p style="text-indent:25px">微觀上來講，砂型強度是靠砂子之間以及砂子與砂箱直接的摩擦力建立的。砂箱四壁和箱帶都對砂子有較強的摩擦力，也就加強了其附近砂型的強度。某廠在采用V法工藝生產(chǎn)球鐵橋殼過程中，由于砂箱未加箱檔或抽氣管，盡管系統(tǒng)真空度較高，但是鑄型強度及剛性不足，完全抵擋不住球墨鑄**固過程中的石墨化膨脹，嚴重脹箱，造成鑄件內(nèi)部組織致密性不夠，同時分型面產(chǎn)生極大的飛邊，致使鑄件報廢。砂箱及鑄件如圖8所示。江陰華天科技開發(fā)有限公司坐落于中國經(jīng)濟發(fā)達的長江三角洲經(jīng)濟區(qū)中心的江蘇省江陰市，專業(yè)從事氣力輸送系統(tǒng)，V法、消失模、樹脂砂、水玻璃砂鑄造設備，輸送設備及環(huán)保設備的設計制造、安裝調(diào)試。V法鑄造中多采用干式真空泵和水環(huán)真空泵，我國主要采用水環(huán)式真空泵。</p><div

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(jié)劑，干砂回用率高達95%以上，不僅節(jié)能環(huán)保、落砂簡便、改善勞動條件，而且鑄件表面品質(zhì)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，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。通過不同型砂對鑄造工藝、砂處理設備、真空設備和工藝裝備設計的影響。南通負壓V法鑄造設備廠</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(shù)，提升了我國V法鑄造水平。據(jù)粗略統(tǒng)計，國內(nèi)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(jié)構(gòu)焊接而成，由底座支撐架、震實臺、負壓箱、頂箱機構(gòu)等組成，具有結(jié)構(gòu)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(gòu)簡單，更換模板方便，人工操作與機械化造型相結(jié)合，投資少，上馬快，比較適合單件、小批量鑄造車間使用，生產(chǎn)中、小型V法鑄件。面有所突破。
