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(chē)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(mǎn)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。南京真空密封V法鑄造原理對(duì)于V法鑄造企業(yè)，結(jié)合企業(yè)生產(chǎn)和產(chǎn)品特點(diǎn)、V法鑄造特性及其主輔材料的功用。</p><div

style="text-indent:25px">目前，大部分廠家已經(jīng)采用頂桿起模機(jī)（見(jiàn)圖6），甚至自動(dòng)化程度更高的機(jī)械手完成起模動(dòng)作（見(jiàn)圖7）。相比之前的行車(chē)起模和簡(jiǎn)單的千斤頂起模方式來(lái)說(shuō)，起模的安全性和穩(wěn)定性已經(jīng)有了很大進(jìn)步。但是，在越來(lái)越多精密鑄件成形的過(guò)程中，逐漸發(fā)現(xiàn)部分起模頂桿或者機(jī)械手的精度和強(qiáng)度問(wèn)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(dá)標(biāo)，或者不經(jīng)過(guò)應(yīng)有的熱處理工藝，造型起模頂桿強(qiáng)度和剛性不足。再加上加工或安裝精度不夠，造成起模過(guò)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(diǎn)。</p><p>

長(zhǎng)期以來(lái)，國(guó)內(nèi)V法鑄造生產(chǎn)線布局設(shè)計(jì)及關(guān)鍵技術(shù)的水平不高，砂箱等關(guān)鍵工裝設(shè)備結(jié)構(gòu)單一，難以滿(mǎn)足多種類(lèi)產(chǎn)品的工藝生產(chǎn)要求。因此有必要在摸清楚V法鑄造耐磨鑄件工藝生產(chǎn)特點(diǎn)的基礎(chǔ)上，為實(shí)現(xiàn)工藝要求對(duì)設(shè)備進(jìn)行相應(yīng)的研發(fā)設(shè)計(jì)，配套不同類(lèi)型的生產(chǎn)線形式以滿(mǎn)足不同企業(yè)的需求。以砂箱為例，砂箱結(jié)構(gòu)設(shè)計(jì)作為V法鑄造生產(chǎn)線的**內(nèi)容，是保障產(chǎn)品質(zhì)量的****裝備。在以往的生產(chǎn)經(jīng)驗(yàn)中，因?yàn)樯跋浣Y(jié)構(gòu)問(wèn)題引起的生產(chǎn)問(wèn)題層出不窮。對(duì)于V法鑄造生產(chǎn)耐磨鑄件，砂箱尺寸往往龐大；如何實(shí)現(xiàn)多品種鑄件的生產(chǎn)，在保障砂箱通用性的基礎(chǔ)上盡可能滿(mǎn)足冒口等工藝布置的要求，同時(shí)還便于生產(chǎn)組織管理和砂箱自身維護(hù)，都是砂箱設(shè)計(jì)需要重點(diǎn)關(guān)注的部分。除此之外，真空系統(tǒng)的使用和控制，生產(chǎn)線布局形式的設(shè)計(jì)及生產(chǎn)節(jié)奏的安排都將是耐磨件V法鑄造生產(chǎn)所用裝備重點(diǎn)研究的部分。涂料是保證鑄件表面質(zhì)量，防止粘砂的關(guān)鍵；</p><div
