對于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。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，泰州真空密封V法鑄造特點(diǎn)，泰州真空密封V法鑄造特點(diǎn)，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。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，泰州真空密封V法鑄造特點(diǎn)、砂型硬度不夠，澆注過程中甚至?xí)纱水a(chǎn)生砂型垮塌。除塵濾氣罐采用介質(zhì)分離，抽吸進(jìn)來的氣體與水混合。泰州真空密封V法鑄造特點(diǎn)</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="泰州真空密封V法鑄造特點(diǎn),V法鑄造" src="https://tyunfile.71360.com/UploadFile/Jyhuatian/637293889985097657/1146380.png"></div><p> V法鑄造投資少，砂處理系統(tǒng)較為簡單，運(yùn)行能耗少。 </p> <p> 與其他砂型鑄造相比，V法鑄造環(huán)境友好，生產(chǎn)現(xiàn)場噪音低，鑄件拋丸清理量減少50%以上，勞動力減少35%以上。澆注時(shí)，薄膜、涂料和樹脂砂芯產(chǎn)生的煙氣都被真空系統(tǒng)抽走，經(jīng)過干濕過濾后排空，對大氣污染少；V法固體廢棄物少，干砂再生高達(dá)95％。符合節(jié)能減排的高要求。 </p> <p> V法優(yōu)勢鮮明，其弊端也很突出： </p> <p> 受到薄膜延伸性能的局限，V法鑄造不適宜生產(chǎn)外形復(fù)雜鑄件； </p> <p> V法制芯技術(shù)還不成熟，采用樹脂砂芯或水玻璃砂芯才能鑄造內(nèi)腔復(fù)雜鑄件； </p> <p> 真空系統(tǒng)需隨時(shí)與砂型相連； </p> <p> V法鑄造不適合生產(chǎn)小型鑄件，生產(chǎn)效率難以提高； </p> <p> V法鑄鋼易出現(xiàn)氣孔和夾渣等鑄造缺點(diǎn)，尤其低碳鋼件有較嚴(yán)重的增碳。泰州質(zhì)量V法鑄造鋁合金多采用開放式澆注系統(tǒng)F直∶F橫∶F內(nèi)＝1∶(2～3)∶(1～5)，**小截面積比砂型鑄造大20～30%；</p><div

style="text-indent:25px">目前，大部分廠家已經(jīng)采用頂桿起模機(jī)（見圖6），甚至自動化程度更高的機(jī)械手完成起模動作（見圖7）。相比之前的行車起模和簡單的千斤頂起模方式來說，起模的安全性和穩(wěn)定性已經(jīng)有了很大進(jìn)步。但是，在越來越多精密鑄件成形的過程中，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> 重視工藝試驗(yàn)和工藝過程的積累 </p> <p> 通過工藝試驗(yàn)過程的開展，理解耐磨鑄件V法鑄造工藝路線，熟知工藝控制要點(diǎn)及比較好工藝參數(shù)，對于V法鑄造項(xiàng)目的順利開展具有重要意義。V法鑄造在國內(nèi)推廣早期，上述環(huán)節(jié)的缺失為不少企業(yè)釀成了重大損失，目前逐漸引起越來越多企業(yè)的重視。尤其是真空的使用和控制是V法鑄造工藝有別于傳統(tǒng)砂型鑄造的重要特征，深刻的影響著產(chǎn)品質(zhì)量和生產(chǎn)管理過程的控制等。從國外耐磨企業(yè)案例不難看出，在其探索過程中，同樣經(jīng)過了足夠的產(chǎn)品生產(chǎn)試驗(yàn)，從單件到小批量，從簡易工藝設(shè)備到大型生產(chǎn)線，在充分分析工藝過程的基礎(chǔ)上，對相應(yīng)V法工藝裝備及生產(chǎn)線有了更充分的認(rèn)識和風(fēng)險(xiǎn)預(yù)判，為后續(xù)的批量化生產(chǎn)奠定了基礎(chǔ)。金屬液平穩(wěn)充型，避免沖刷鑄型或產(chǎn)生飛濺，一般采用底注半封閉式或開放式澆注系統(tǒng)。</p><div

style="text-indent:25px">正確選用塑料薄膜，型砂，真空泵﹑負(fù)壓度、振動時(shí)間和結(jié)構(gòu)合理的砂箱是獲得質(zhì)量V法鑄件的基礎(chǔ)；泰州真空密封V法鑄造特點(diǎn)</p><p> V法具有與傳統(tǒng)砂型鑄造無法比擬的優(yōu)勢，其具體表現(xiàn)在以下七個(gè)方面： </p> <p> 造型易起模，模具少無磨損，金屬模具壽命長，模具可用木質(zhì)材料； </p> <p> 鑄件尺寸精度高，輪廓清晰，鑄鐵件粗糙度值達(dá)Ra18—25μm。叉車鑄鐵配重是V法鑄造產(chǎn)品的典型**。安徽合力叉車集團(tuán)合肥鑄鍛廠生產(chǎn)的叉車配重，曾獲2002年第四屆北京國際鑄造工業(yè)展覽會鑄件一等獎。世界上叉車和其他工程車所需配重和平衡塊幾乎都是V法鑄造生產(chǎn)的；(3) V法干砂保溫效果和真空抽吸作用都能提高金屬液的流動性。試驗(yàn)表明：V法鑄造和濕型鑄造相比，金屬液流動性可提高27％。因此V法鑄造不*能生產(chǎn)厚壁鑄件，也能生產(chǎn)薄壁鑄件。如南京東陶（TOTO）有限公司引進(jìn)日本新東鑄造生產(chǎn)線，生產(chǎn)***鑄鐵浴缸，比較大浴缸尺寸為1829mm×1067mm×650mm，鑄件重達(dá)180kg，壁厚7mm，如圖2所示。圖3 天津英昌鋼琴鑄件有限公司生產(chǎn)的鋼琴鑄鐵弦架也是V法鑄造薄壁件的典型產(chǎn)品。泰州真空密封V法鑄造特點(diǎn)</p><p
