style="text-indent:25px">V法工藝生產(chǎn)耐磨鑄件的發(fā)展V法鑄造1973年起源于日本，80年代引入中國后得到了***關(guān)注，并逐步應(yīng)用于很多產(chǎn)品的生產(chǎn)。同時，該工藝傳入北美及歐洲地區(qū)，取得了長足發(fā)展，應(yīng)用范圍不斷擴展，在叉車配重、工程機械橋殼、浴盆等領(lǐng)域獲得了非常成熟的應(yīng)用。在耐磨鑄件領(lǐng)域，V法鑄造工藝在瑞典山特維克、美國耐磨狼、美伊電鋼等**耐磨鑄件生產(chǎn)企業(yè)的使用中獲得了極大成功，并逐步成為這些企業(yè)的主流工藝。在國內(nèi)，從上世紀(jì)80年代開始有初步探索該工藝生產(chǎn)耐磨鑄件的試驗，但是沒有成熟應(yīng)用（除鐵路道岔外）。近些年，在耐磨鑄件生產(chǎn)領(lǐng)域，V法鑄造工藝重新得到重視和關(guān)注。目前，V法鑄造在耐磨鑄件的生產(chǎn)應(yīng)用方面主要以傳統(tǒng)礦山耐磨鑄件為主，包括高錳鋼圓錐、齒板、錘頭、板錘、大型襯板等。甚至有些企業(yè)成功將立磨所用高鉻輥套鑄件采用V法鑄造工藝生產(chǎn)，取得了不錯的效果。</p><p> V法鑄造用塑料薄膜厚為0.03～0.25mm。覆膜成型是將塑料薄膜加熱軟化，利用真空將薄膜吸附在凹凸不平的模樣表面上（如圖3.2所示）。由于模樣輪廓結(jié)構(gòu)復(fù)雜多樣，要求塑料薄膜具有較好的延伸性，不易產(chǎn)生折痕和破裂。塑料簿膜在模樣或芯盒內(nèi)的成型能力直接影響鑄件的表面光潔度和尺寸精度，因而V法鑄造的薄膜須具有以下要求： </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(dǎo)柱導(dǎo)套所用材質(zhì)的質(zhì)量和數(shù)量不夠達標(biāo)，或者不經(jīng)過應(yīng)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。但澆注時負(fù)壓度的變化大，澆注瞬間，負(fù)壓度下降快，澆注完畢后鑄型能恢復(fù)并保持較高的負(fù)壓度。無錫實型V法鑄造裝備</p><p

style="text-indent:25px">V法鑄造是真空密封造型或負(fù)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。無錫先進V法鑄造</p><p
