對(duì)于V法鑄造工藝的設(shè)計(jì)，不是只完成單個(gè)鑄件的工藝設(shè)計(jì)，應(yīng)該是先完成單個(gè)鑄件的澆冒口系統(tǒng)、砂芯設(shè)計(jì)、透氣設(shè)計(jì)、冷鐵等的設(shè)計(jì)，然后，根據(jù)工廠現(xiàn)有V法裝備的實(shí)際和生產(chǎn)效率等進(jìn)行模具的工藝布置設(shè)計(jì)，合理布置，重新進(jìn)行澆注系統(tǒng)的優(yōu)化設(shè)計(jì)。之后進(jìn)行模型體和型板上的抽氣塞設(shè)計(jì)(大小、位置、間距等設(shè)計(jì))，抽氣塞的設(shè)計(jì)必須自行進(jìn)行，不能交由模具設(shè)計(jì)和制作單位進(jìn)行，抽氣塞設(shè)計(jì)是否合理對(duì)后續(xù)生產(chǎn)中的覆膜效果影響很大，同時(shí)影響生產(chǎn)中抽氣塞破損、堵塞后的更換，南通實(shí)型V法鑄造企業(yè)。上述工作完成之后開始進(jìn)行砂箱的設(shè)計(jì)工作，抽氣布局要合理，尤其是澆口和冒口附近，由于薄膜氣化和涂層受熱嚴(yán)重，真空泄漏較多，應(yīng)在該部位增大真空抽氣量，保證該部位的負(fù)壓滿足實(shí)際需要，南通實(shí)型V法鑄造企業(yè)。在進(jìn)行砂箱設(shè)計(jì)時(shí)，不能只考慮真空度是否滿足，砂箱的負(fù)壓室容積必須保證足夠的抽氣量，否則，即便是真空度足夠，抽氣量不足同樣造成鑄型緊實(shí)率不足、砂型硬度不夠，澆注過程中甚至?xí)纱水a(chǎn)生砂型垮塌，南通實(shí)型V法鑄造企業(yè)。通過不同型砂對(duì)鑄造工藝、砂處理設(shè)備、真空設(shè)備和工藝裝備設(shè)計(jì)的影響。南通實(shí)型V法鑄造企業(yè)</p><div

V法鑄造工藝不產(chǎn)生廢棄物污染，采用合理有效的除塵手段即可收集鑄造過程中產(chǎn)生的粉塵，排放量可嚴(yán)格達(dá)到國(guó)家環(huán)保要求。 </p> <p> 從國(guó)內(nèi)大部分耐磨企業(yè)的生產(chǎn)情況來看，以上優(yōu)勢(shì)并沒有完全在生產(chǎn)中發(fā)揮出來，這與我們對(duì)V法鑄造工藝的認(rèn)識(shí)欠缺，對(duì)基礎(chǔ)研究的投入以及對(duì)設(shè)備輔材的配套研究不足有很大關(guān)系。 </p> <p> 4技術(shù)發(fā)展水平方面 </p> <p> V法鑄造在國(guó)內(nèi)發(fā)展的時(shí)間有限，局限于鑄造設(shè)備企業(yè)的研發(fā)創(chuàng)新能力，V法鑄造生產(chǎn)線形式單一，難以針對(duì)特殊鑄件開發(fā)**裝備，這也是V法鑄造在國(guó)內(nèi)耐磨件生產(chǎn)方面受到局限的問題之一。目前國(guó)內(nèi)多數(shù)生產(chǎn)線仍然采用傳統(tǒng)的布局形式，生產(chǎn)線效率低，控制水平差異導(dǎo)致生產(chǎn)過程不穩(wěn)定，產(chǎn)品質(zhì)量難以達(dá)到V法應(yīng)有的質(zhì)量水平，同時(shí)行業(yè)內(nèi)又缺乏高水平的先進(jìn)V法鑄造生產(chǎn)線及相關(guān)裝備企業(yè)。南通密封V法鑄造工藝國(guó)家環(huán)保的壓力更是推動(dòng)了部分不符合標(biāo)準(zhǔn)的小企業(yè)加快了這一實(shí)驗(yàn)的腳步。</p><div

耐磨鑄造車間的建設(shè)是一個(gè)系統(tǒng)工程，除了生產(chǎn)設(shè)備本身外，車間布局物流設(shè)計(jì)，原輔材料的配套，熱處理系統(tǒng)的配套，機(jī)加工設(shè)備的配套等都要作為系統(tǒng)的一部分考慮。 </p> <p> 以砂箱的周轉(zhuǎn)為例，耐磨鑄件由于保溫冷卻時(shí)間長(zhǎng)，在一定程度上限制了砂箱的流轉(zhuǎn)速度，企業(yè)訂購大量砂箱不僅**增加了企業(yè)成本，而且造成管理使用上的困難?？赏ㄟ^采用建設(shè)冷卻立體庫，設(shè)計(jì)冷卻托盤的方式加快砂箱流轉(zhuǎn)，同時(shí)節(jié)約生產(chǎn)場(chǎng)地。標(biāo)準(zhǔn)化托盤的設(shè)計(jì)和制作，滿足叉車運(yùn)輸條件，并不額外增加過多的勞動(dòng)力，實(shí)現(xiàn)了工藝生產(chǎn)的要求，降低了設(shè)備投資成本，同時(shí)提高的系統(tǒng)運(yùn)行效率。 </p><p 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。開設(shè)補(bǔ)縮冒口須根據(jù)砂型鑄造工藝原則、V法鑄造工藝特點(diǎn)及鑄件特點(diǎn)等具體確定。</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)。負(fù)壓澆注，有利于金屬的補(bǔ)給，鑄件冒口可減小，鑄件表面光潔，尺寸精度高，加工余量減少。南通密封V法鑄造工藝</p><p
