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，南京真空V法鑄造裝備，南京真空V法鑄造裝備，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(shù)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。分析砂溫對砂處理設(shè)備設(shè)計和鑄件質(zhì)量控制的影響，從而科學和適宜地進行砂溫控制。南京真空V法鑄造裝備</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

國內(nèi)V法薄膜生產(chǎn)企業(yè)主要有武漢恒德科技有限公司、北京華盾塑料公司、天津市萊沃商貿(mào)有限公司等。其中，武漢恒德科技有限公司是我國比較大的V法**EVA薄膜生產(chǎn)企業(yè)，該公司現(xiàn)有4條生產(chǎn)線，具備日產(chǎn)12 t不同規(guī)格EVA薄膜的能力。 </p> <p> 該公司不斷改進基于EVA的V法**膜，其醋酸乙烯含量(質(zhì)量分數(shù)，下同)為18%-20%，維卡軟化點為70℃。添加山茶植物油提煉的外潤滑劑等輔料，使其伸長率較高，縱向達到717 % ,橫向達到589，接近日本同類產(chǎn)品。目前，V法鑄造用EVA鑄型薄膜的行業(yè)標準正在制訂中。南京真空V法鑄造裝備實際生產(chǎn)中，一般依據(jù)真空罐上的真空表及砂箱外管道上的真空表反映的負壓度來調(diào)節(jié)生產(chǎn)時的負壓度。</p><div style="width:100%;text-align: center;"><img

自主創(chuàng)新、擁有自主知識產(chǎn)權(quán)的大型V法造型線 </p> <p> 國內(nèi)生產(chǎn)大型V法造型線的公司，其中有江陰華天科技開發(fā)有限公司。該公司研制成功國內(nèi)首條自主創(chuàng)新、擁有自主知識產(chǎn)權(quán)的大型V法造型線，標志著V法鑄造生產(chǎn)線依賴進口的歷史結(jié)束。 </p> <p> 法鑄造**模具企業(yè)采用CAD/CAM技術(shù) </p> <p> 干燥良好的無缺點木材是V法鑄造常用模具材料。金屬材料價格昂貴，而且鉆孔較困難，并不太適合用于V法模具。另外暴露于薄膜加熱器下的金屬模具受重復加熱作用，溫度上升后易粘薄膜。因此V法鑄造企業(yè)長期采用木質(zhì)材料制模，而其大多是靠模型工放樣半機械化制作。其尺寸精度較差和生產(chǎn)周期較長一直是V法鑄造的瓶頸。 </p><p>?V法造型用砂箱除四壁要密封外，砂箱內(nèi)部必須裝設(shè)抽氣過濾裝置，如圖3.4所示。按抽氣方式V法砂箱可分為側(cè)面抽氣式、管式抽氣式及金屬軟管抽氣和管式抽氣式復合砂箱。<br></p><p>①側(cè)面抽氣式砂箱是用鋼板焊成的密封夾層，夾層之間形成連通的抽氣室，類似消失模用砂箱；<br></p><p>②管式抽氣砂箱。該結(jié)構(gòu)砂箱的端壁是用鋼板焊成的密封夾層，夾層的中空部分形成抽氣室，而側(cè)壁是實體的，抽氣孔為焊于兩端壁上與抽氣室連通的數(shù)根抽氣管（孔間距25 mm左右，孔徑8～10 mm），在鋼管外面包兩層120～150目的金屬網(wǎng)，以防止細紗及粉塵被吸入抽氣室。適用于面積大于1200×1200mm中大型砂箱。<br>當負壓度小于0.038MPa時，鑄型易發(fā)生脹箱、變形及塌砂。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="text-indent:25px">對于一些多筋板或具有相當高垂直面的鑄件而言，這種擦傷鑄型的現(xiàn)象尤為普遍。而個別自動化程度很高的機械手，運轉(zhuǎn)穩(wěn)定性差，末端柔性不足，在運轉(zhuǎn)過程中產(chǎn)生震蕩或者難以急停，甚至不能保證**起碼的定位及真空對接精度，直接影響鑄型在起模翻轉(zhuǎn)等過程中的安全性。隨著V法成套裝備生產(chǎn)線自動化和機械化水平的提升，對起模機構(gòu)的使用要求越來越高。這就需要我們在這些關(guān)鍵的造型設(shè)備方面，提高設(shè)計，制造，安裝的精度和可靠性，以充分保障造型質(zhì)量和鑄型安全。真空密封造型緊實原理是利用塑料薄膜密封砂箱，依靠真空抽出型內(nèi)的空氣造成鑄型內(nèi)外壓力差使干砂緊實。揚州密封V法鑄造設(shè)備</p><p

style="text-indent:25px">V法鑄造用的砂箱，其結(jié)構(gòu)形式直接決定著砂箱內(nèi)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(guān)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(chǎn)出鑄件。然而，產(chǎn)生的影響卻是不一樣的。生產(chǎn)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?。粚嶋H上，對于砂箱來說，真空的形成是氣體流動的結(jié)果，是型腔內(nèi)的空氣被真空系統(tǒng)抽走之后形成的。南京真空V法鑄造裝備</p><p
