長(zhǎng)期以來，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，難以滿足多種類產(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)，配套不同類型的生產(chǎn)線形式以滿足不同企業(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)問題引起的生產(chǎn)問題層出不窮。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。揚(yáng)州真空V法鑄造原理為增加干砂的堆積密度，采用高頻率低振幅的振動(dòng)方式使砂箱中干砂緊實(shí)。</p><div

style="text-indent:25px">鑄型強(qiáng)度不夠或者不均勻，在有些具有大平面特點(diǎn)的鑄件生產(chǎn)上，不能很好的減小或防止鑄件在冷卻過程中的變形。有時(shí)候常常為了落砂的簡(jiǎn)易性，對(duì)于下箱往往不加箱檔，以利于鑄件直接從砂箱脫出。這是不合理的。上下箱必須都設(shè)計(jì)抽氣箱檔，才能有效保障鑄型強(qiáng)度的均勻性及上下鑄型強(qiáng)度的對(duì)等性。圖9、圖10為某廠生產(chǎn)某種型號(hào)的鐵路側(cè)架鑄件的上下箱結(jié)構(gòu)圖。另外值得一提的是，砂箱結(jié)構(gòu)設(shè)計(jì)合理，對(duì)于同一套真空系統(tǒng)來講，可能同時(shí)允許接入的砂箱數(shù)量就會(huì)增加，意味著真空系統(tǒng)的利用效率明顯增強(qiáng)。</p><p>
