V法鑄造引入我國至今已有30多年的發(fā)展，而V法鑄造裝備則經(jīng)歷了從無到有以及由對外引進仿制，到自主研發(fā)設(shè)計的過程。V法鑄造裝備質(zhì)量水平的提升，也進一步保障并促進了V法鑄造工藝的拓展，南通V法鑄造原理。據(jù)不完全統(tǒng)計，南通V法鑄造原理，目前國內(nèi)約有400多條形式各異的V法鑄造生產(chǎn)線在運行，既有極其簡易甚至不配套砂處理的單機造型設(shè)備，也有比較常見且配置相對***的半自動鑄造生產(chǎn)線，更有機械化，自動化程度較高，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。尤其是造型過程中覆膜成形，加砂震實，南通V法鑄造原理，抽真空起模工序，相應設(shè)備工裝的特點明顯影響著鑄型和鑄件質(zhì)量。而鑄鋼件多采用開放式澆注系統(tǒng)，其澆道截面積比例為F直∶F橫∶F內(nèi)＝1∶(1．2～2)∶(1．2～2)

該造型機組由上箱和下箱造型。在臺車造型機上完成覆膜、噴（刷）涂料、涂料烘干，而后臺車移至砂斗下加砂振實后又移出復位蓋膜、抽真空、頂箱起模，吊車將鑄型吊走。電動臺車在固定的軌道上前后移動，臺車上裝有震實臺、負壓箱、型板及模樣。電加熱器在臺車的上部，有移動機構(gòu)可兼管2臺造型機使用，用人工烘烤覆膜，也可設(shè)計成自動加熱覆膜機。覆膜抽真空后噴（刷）涂料而后進行涂料烘干，放置砂箱。完成上述工序后，驅(qū)動臺車至砂斗下，空氣彈簧進氣，抬起震實臺以上部分與加砂斗的雨淋下砂口對接，驅(qū)動下砂氣缸，向砂箱加砂而后振實。當達到所需要時間后，震實停止，震實臺下降，電動臺車移至原位，蓋膜并給鑄型抽真空，當鑄型達到一定的緊實度后，移到頂箱機構(gòu)處進行頂箱起模后，用吊車運至合箱處。江陰華天科技開發(fā)有限公司為福建龍巖盛豐機械制造有限公司和中恒通（福建）機械制造有限公司設(shè)計的V法生產(chǎn)線就是采用這種形式，主要生產(chǎn)載重車后橋和制動鼓，各種叉車，裝載機及其他機械設(shè)備用平衡重類灰鑄鐵件，生產(chǎn)**10000t/年，造型生產(chǎn)率8～10型/h，比較大砂箱內(nèi)尺寸2000×1400×320/360mm。南通先進V法鑄造生產(chǎn)線正確選用塑料薄膜，型砂，真空泵﹑負壓度、振動時間和結(jié)構(gòu)合理的砂箱是獲得質(zhì)量V法鑄件的基礎(chǔ)；</p><div

V法鑄造生產(chǎn)線的砂處理系統(tǒng)主要解決四個問題：一是去除舊砂中存在的鐵屑、鐵渣等雜物；二是去除舊砂斗中薄膜及砂芯的殘渣；三是落砂后的熱砂降溫至所需的溫度范圍；四是整個砂處理系統(tǒng)的除塵和吸塵保證舊砂的再生質(zhì)量和環(huán)保的要求。一般V法所用砂含泥量低于0.3～0.5%之內(nèi)。 </p> <p> 去除舊砂中的鐵性雜物一般采用貫通式或懸掛式永磁分選機。去除舊砂中的薄膜及砂芯等殘渣物，一般選用慣性直線振動篩和復合式篩分機。熱砂冷卻一般選用固定式流化床砂溫調(diào)節(jié)裝置或冷卻滾筒。除塵系統(tǒng)一般采用集中除塵，將落砂、篩分、冷卻、機運等揚塵點集中處理，選用旋風除塵器與袋式除塵組合式，均能達到良好的除塵效果。 </p> </p> <p> <br /> </p><p> 耐磨鑄件是采礦、冶金、建材、電力、石化、機械、交通等重要工業(yè)領(lǐng)域的消耗品，在工業(yè)生產(chǎn)中占有重要地位。據(jù)不完全統(tǒng)計, 國內(nèi)年消耗量超過200 萬t , 目前已有近千家耐磨鑄件生產(chǎn)企業(yè), 年生產(chǎn)能力達到500 萬噸以上，鑄造工藝多種多樣。 </p> <p> 耐磨鑄件工藝現(xiàn)狀 </p> <p> 目前，耐磨鑄件普遍采用水玻璃砂，堿酚醛樹脂砂鑄造工藝，也有部分采用消失模鑄造工藝。這些工藝靈活穩(wěn)定，工藝成熟度較相對較高，能夠?qū)崿F(xiàn)穩(wěn)定批量化生產(chǎn)，是耐磨鑄件生產(chǎn)的傳統(tǒng)工藝。但尤其是水玻璃砂、樹脂砂工藝同時存在著勞動強度大，人均生產(chǎn)效率低的弊端，在環(huán)保問題日益嚴峻、勞動力成本越來越高的***，傳統(tǒng)工藝面臨著較大的壓力。 </p> <p> 結(jié)合產(chǎn)業(yè)升級的趨勢，國內(nèi)部分企業(yè)探索V法鑄造工藝生產(chǎn)耐磨鑄件，產(chǎn)品類型以軋臼壁、破碎壁、齒板、錘頭等中大型鑄件為主，所生產(chǎn)的鑄件具有表面質(zhì)量好，尺寸精度高的優(yōu)勢，同時造型落砂等工序勞動強度低，具有相對比較好的環(huán)保優(yōu)勢。涂料是保證鑄件表面質(zhì)量，防止粘砂的關(guān)鍵；</p><div

src="https://tyunfile.71360.com/UploadFile/Jyhuatian/637293889985097657/1146380.png"></div><p>?V法造型用砂箱除四壁要密封外，砂箱內(nèi)部必須裝設(shè)抽氣過濾裝置，如圖3.4所示。按抽氣方式V法砂箱可分為側(cè)面抽氣式、管式抽氣式及金屬軟管抽氣和管式抽氣式復合砂箱。<br></p><p>①側(cè)面抽氣式砂箱是用鋼板焊成的密封夾層，夾層之間形成連通的抽氣室，類似消失模用砂箱；<br></p><p>②管式抽氣砂箱。該結(jié)構(gòu)砂箱的端壁是用鋼板焊成的密封夾層，夾層的中空部分形成抽氣室，而側(cè)壁是實體的，抽氣孔為焊于兩端壁上與抽氣室連通的數(shù)根抽氣管（孔間距25 mm左右，孔徑8～10 mm），在鋼管外面包兩層120～150目的金屬網(wǎng)，以防止細紗及粉塵被吸入抽氣室。適用于面積大于1200×1200mm中大型砂箱。<br>利用高爐鐵水的熱量，大幅減少能源消耗，同時降污染物排放，節(jié)能，環(huán)保和經(jīng)濟效益。南通先進V法鑄造生產(chǎn)線</p><p style="text-indent:25px">為增加干砂的堆積密度，采用高頻率低振幅的振動方式使砂箱中干砂緊實。南通V法鑄造原理</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法鑄造不僅能生產(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。南通V法鑄造原理</p><p
