style="text-indent:25px">V法造型過(guò)程中，震動(dòng)是獲得高緊實(shí)度砂型的重要環(huán)節(jié)。V法鑄型的硬度和強(qiáng)度，不僅與我們常規(guī)理解中的砂箱的真空度有關(guān)系，震實(shí)效果也是很重要的一方面（如圖4所示）。在震實(shí)不夠的情況下，有時(shí)候通過(guò)高的真空度，可以獲得較高的鑄型硬度，但這只是一種假象，砂型強(qiáng)度往往是不足的。在砂型抽真空，翻轉(zhuǎn)，轉(zhuǎn)運(yùn)，合箱，澆注等過(guò)程中產(chǎn)生的波動(dòng)又會(huì)造成鑄型內(nèi)砂子形位的重新排布進(jìn)而引起鑄型強(qiáng)度，結(jié)構(gòu)尺寸等的變化。而這些變化反映到鑄件上，則表現(xiàn)出鑄件尺寸或者重量精度超差等質(zhì)量問(wèn)題。目前在震實(shí)臺(tái)設(shè)計(jì)中，對(duì)于振幅，震動(dòng)頻率，激振力及如何配置振動(dòng)電機(jī)等問(wèn)題往往模棱兩可，缺乏基本的核算依據(jù)。泰州專業(yè)V法鑄造生產(chǎn)線真空密封造型緊實(shí)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(shí)。</p><div

style="text-indent:25px">對(duì)于一些多筋板或具有相當(dāng)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(gè)別自動(dòng)化程度很高的機(jī)械手，運(yùn)轉(zhuǎn)穩(wěn)定性差，末端柔性不足，在運(yùn)轉(zhuǎn)過(guò)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(duì)接精度，直接影響鑄型在起模翻轉(zhuǎn)等過(guò)程中的安全性。隨著V法成套裝備生產(chǎn)線自動(dòng)化和機(jī)械化水平的提升，對(duì)起模機(jī)構(gòu)的使用要求越來(lái)越高。這就需要我們?cè)谶@些關(guān)鍵的造型設(shè)備方面，提高設(shè)計(jì)，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。</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(fù)壓場(chǎng)的形成和分布，也就決定著鑄型強(qiáng)度的大小和均勻性。但是，不少觀念錯(cuò)誤的認(rèn)為，只要砂箱里面能夠抽氣就行，至于怎么抽，抽多少，都無(wú)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(fù)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(dá)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(xí)慣了用真空度來(lái)衡量或者表征鑄型的強(qiáng)度，認(rèn)為真空度越高，鑄型強(qiáng)度越高，塌箱的幾率也越?。粚?shí)際上，對(duì)于砂箱來(lái)說(shuō)，真空的形成是氣體流動(dòng)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。V法鑄造是設(shè)備﹑工藝和原輔材料相互配合協(xié)調(diào)平衡的有機(jī)結(jié)合，要全盤(pán)考慮協(xié)調(diào)的系統(tǒng)工程。</p><div

耐火涂料的使用在V法鑄造中起到至關(guān)重要的作用。涂料層的性能不僅影響薄膜氣化氣體的遷移，而且與鑄件表面質(zhì)量密切相關(guān)。涂料載液一般選用乙醇、甲醇或異丙醇，綜合實(shí)踐一般選用乙醇含量大于95％的工業(yè)酒精，沸點(diǎn)為70℃，密度0．8g／cm，閃點(diǎn)12℃。V法鑄造用涂料應(yīng)具有以下基本要求： </p> <p> 不與塑料薄膜反應(yīng)，***無(wú)味； </p> <p> 具有好的懸浮性和強(qiáng)韌性，涂料層有高的透氣性及良好的抗機(jī)械滲透粘砂的能力； </p> <p> 較高耐火度，其中應(yīng)含有耐火度較高的礦物和耐火度相對(duì)較低、易燒結(jié)的組分，燒結(jié)形成剝離層，清理時(shí)易潰散； </p> <p> 要有較小的發(fā)氣量，良好的流動(dòng)性和觸變性； </p> <p> 較高附著力，涂料能牢固的粘附在塑料薄膜上形成致密的涂層。穩(wěn)壓除塵濾氣罐。穩(wěn)壓罐主要作用是穩(wěn)定真空系統(tǒng)壓力，緩沖系統(tǒng)壓力波動(dòng)對(duì)造型、澆注的影響。南京密封V法鑄造介紹</p><p

V法工藝是70年代初發(fā)明的一種新的鑄造工藝方法，近幾年在我國(guó)應(yīng)用發(fā)展的很快，已從鑄造叉車配重、浴盆等鑄鐵鑄件發(fā)展到鑄鋼、鑄銅、鑄鋁加工件。但是一些形狀比較復(fù)雜的鑄件給覆膜帶來(lái)困難，有的需配多件砂芯。影響了造型效率，增加成本，使V法鑄造工藝的推廣應(yīng)用受到限制。 </p> <p> 我們是推廣應(yīng)用V法鑄造工藝和消失模鑄造工藝的企業(yè)。我們?cè)谕茝V過(guò)程中發(fā)現(xiàn)，將兩種工藝結(jié)合在一起，取長(zhǎng)補(bǔ)短，可以簡(jiǎn)化覆膜，提高覆膜質(zhì)量，提高鑄件質(zhì)量，減薄EVA薄膜厚度，減少砂芯用量，提高造型效率，降低V法鑄造成本，效果明顯。我們?cè)趹?yīng)用上進(jìn)行一些探討，試用，取得了明顯的效果。我們將這一工藝叫做《消失模鑄造工藝嫁接到V法鑄造工藝的新方法》供同行們參考，共同開(kāi)發(fā)這一工藝。泰州質(zhì)量V法鑄造工藝</p><p
