V法鑄造引入我國(guó)至今已有30多年的發(fā)展，而V法鑄造裝備則經(jīng)歷了從無(wú)到有以及由對(duì)外引進(jìn)仿制，到自主研發(fā)設(shè)計(jì)的過(guò)程。V法鑄造裝備質(zhì)量水平的提升，也進(jìn)一步保障并促進(jìn)了V法鑄造工藝的拓展。據(jù)不完全統(tǒng)計(jì)，目前國(guó)內(nèi)約有400多條形式各異的V法鑄造生產(chǎn)線在運(yùn)行，既有極其簡(jiǎn)易甚至不配套砂處理的單機(jī)造型設(shè)備，也有比較常見(jiàn)且配置相對(duì)***的半自動(dòng)鑄造生產(chǎn)線，更有機(jī)械化，自動(dòng)化程度較高，投資規(guī)模龐大的現(xiàn)代化V法鑄造車間。但是根據(jù)大量的調(diào)研與實(shí)踐，發(fā)現(xiàn)部分設(shè)備和工裝難以滿足鑄件產(chǎn)品的生產(chǎn)工藝要求，致使生產(chǎn)受阻或產(chǎn)品質(zhì)量難以保證。尤其是造型過(guò)程中覆膜成形，加砂震實(shí)，抽真空起模工序，相應(yīng)設(shè)備工裝的特點(diǎn)明顯影響著鑄型和鑄件質(zhì)量。無(wú)錫V法鑄造設(shè)備廠除塵濾氣罐的主要作用是防止細(xì)砂和粉塵進(jìn)入泵內(nèi)，磨損機(jī)械零件，影響泵的正常工作。</p><div

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(jiǎn)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(shí)，形成所需型腔。其比較大優(yōu)勢(shì)是型砂不使用粘結(jié)劑，干砂回用率高達(dá)95%以上，不僅節(jié)能環(huán)保、落砂簡(jiǎn)便、改善勞動(dòng)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(zhǎng)野縣工業(yè)試驗(yàn)所和秋田株式會(huì)社于1971年的發(fā)明專利。V法鑄造至今經(jīng)過(guò)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(guó)獲得了長(zhǎng)足的發(fā)展。</p><p> 覆膜架設(shè)計(jì)對(duì)覆膜成形的影響 </p> <p> 烤膜覆膜作為V法鑄造的第一步，直接影響著整個(gè)造型的質(zhì)量和效率。EVA薄膜只有在加熱烘烤到一定程度的時(shí)候，其延伸性也就是通常所說(shuō)的覆膜成形性能才能達(dá)到比較好狀態(tài)。然而，從烘烤結(jié)束到薄膜下降至模具的過(guò)程中，EVA薄膜由于逐漸遠(yuǎn)離熱源，會(huì)很快冷卻，脫離比較好覆膜狀態(tài)。這就要求覆膜架在極短的時(shí)間內(nèi)，完成覆膜動(dòng)作。大量的工藝實(shí)踐表明，覆膜架在5s內(nèi)下行到位是**為合適的，時(shí)間越長(zhǎng)，對(duì)薄膜原有的熱態(tài)延伸性削減越大。一個(gè)簡(jiǎn)單的公式：t=s/v；（t—覆膜框行走時(shí)間；s—覆膜框行程，即EVA薄膜加熱位置與模具臺(tái)面的距離；v—覆膜框下降的平均速度）顯然，覆膜框行程和下降的速度直接影響著行走時(shí)間，也就影響著覆膜成形的質(zhì)量。正確選擇真空泵以及合理的真空系統(tǒng)是保證V法鑄型穩(wěn)定負(fù)壓度的前提。</p><div
