class="box"><p><p> 重視工藝試驗和工藝過程的積累 </p> <p> 通過工藝試驗過程的開展，理解耐磨鑄件V法鑄造工藝路線，熟知工藝控制要點及比較好工藝參數，對于V法鑄造項目的順利開展具有重要意義。V法鑄造在國內推廣早期，上述環(huán)節(jié)的缺失為不少企業(yè)釀成了重大損失，目前逐漸引起越來越多企業(yè)的重視。尤其是真空的使用和控制是V法鑄造工藝有別于傳統砂型鑄造的重要特征，深刻的影響著產品質量和生產管理過程的控制等。從國外耐磨企業(yè)案例不難看出，在其探索過程中，同樣經過了足夠的產品生產試驗，泰州V法鑄造企業(yè)，從單件到小批量，泰州V法鑄造企業(yè)，從簡易工藝設備到大型生產線，在充分分析工藝過程的基礎上，對相應V法工藝裝備及生產線有了更充分的認識和風險預判，為后續(xù)的批量化生產奠定了基礎，泰州V法鑄造企業(yè)。根據涂料不同骨料組配的特性，合理地選擇V法鑄造用型砂。泰州V法鑄造企業(yè)</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="泰州V法鑄造企業(yè),V法鑄造" src="https://tyunfile.71360.com/UploadFile/Jyhuatian/637293889813476563/989149.png"></div><p> 與傳統濕型相比，V法砂型少無型壁移動，其硬度可達90—95，由于干砂保溫時間長，冒口體積可減少5%—15%。因此V法鑄造可提高金屬液的利用率（球墨鑄鐵件提高約25%，鑄鋼件提高約20%）。V法鑄造適合生產球墨鑄鐵鑄件，也適合生產鑄鋼件。圖4為V法鑄造的球墨鑄鐵后橋。圖5為我國天瑞集團鑄造有限公司V法鑄造的鐵道機車鑄鋼側架。 </p> <p> V法砂型處于真空，不含水份，保溫性能好，很適合生產小批量少無內腔的鋁合金鑄件。日本曾采用大型V法造型機和超大砂箱（7000 mm×4000mm×1000/800mm）生產出鑄鋁游艇殼體（見圖6）。烏克蘭、荷蘭和美國等數家鑄造企業(yè)采用V法生產醫(yī)療，電子，通訊等行業(yè)用的小型鋁鑄件，其鑄件表面質量可與金屬型鑄鋁件媲美。圖7為美國Harmony Casting公司采用V法生產的鑄鋁件，大平面厚度為4.7mm，局部薄至2.3mm。泰州質量V法鑄造特點金屬液平穩(wěn)充型，避免沖刷鑄型或產生飛濺，一般采用底注半封閉式或開放式澆注系統。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="泰州V法鑄造企業(yè),V法鑄造" src="https://tyunfile.71360.com/UploadFile/Jyhuatian/637293889742021485/560378.png"></div><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，主要生產耐酸泵葉輪等不銹鋼鑄件。年產量600～1000t/年，砂箱內尺寸1000×630×150/150mm，比較大砂箱尺寸1000×800×150/150mm，造型生產率10～15型/h。 </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法工藝生產球鐵橋殼過程中，由于砂箱未加箱檔或抽氣管，盡管系統真空度較高，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，造成鑄件內部組織致密性不夠，同時分型面產生極大的飛邊，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濟發(fā)達的長江三角洲經濟區(qū)中心的江蘇省江陰市，專業(yè)從事氣力輸送系統，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、安裝調試。利用短流程工藝來澆注V法鑄造中的特大件如大型配重等也引起了越來越多人的濃厚興趣。</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空氣，造成型內箱外壓力差，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，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。合理的鑄造工藝方案是保證覆膜成型和鑄件質量的一個重要因素。泰州質量V法鑄造特點</p><p
