江陰華天科技開發(fā)有限公司受用戶的委托設計并制造了一條汽車后橋半自動V法鑄造生產(chǎn)線。該生產(chǎn)線。 </p> <p> 本生產(chǎn)線采用4臺移動單機造型機組成的2臺V法造型機組，揚州質(zhì)量V法鑄造工藝，每臺機組的上、下箱分別在兩臺V法造型單機上完成。鑄型成形后用吊車將鑄型吊至合箱小車上進行修型，揚州質(zhì)量V法鑄造工藝、下芯，揚州質(zhì)量V法鑄造工藝、合箱，放置澆冒口杯，整體移至澆注工段進行澆注，冷卻凝固后鑄型連同型板吊至落砂格子板上落砂，舊砂經(jīng)砂冷卻后回用。 </p> <p> 汽車后橋材質(zhì)是鑄鋼；設計生產(chǎn)能力為10000t，實際生產(chǎn)能力為12000t；比較大鑄件質(zhì)量280kg；鑄型砂箱內(nèi)尺寸2000×1400×350/300mm；造型生產(chǎn)能力4-6型/h；砂處理能力20-25t/h；熔煉爐能力t電爐2臺。 </p> <p> <br /> </p> <p> 。 </p> <p> <br /> 模型及砂箱的使用壽命長，用塑料薄膜保護模型，拔模力較小，不受高溫高壓的作用，模型不易變形和損壞。揚州質(zhì)量V法鑄造工藝</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="揚州質(zhì)量V法鑄造工藝,V法鑄造" src="https://tyunfile.71360.com/UploadFile/Jyhuatian/637293889813476563/989149.png"></div><p> V法鑄造投資少，砂處理系統(tǒng)較為簡單，運行能耗少。 </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，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)外形復雜鑄件； </p> <p> V法制芯技術還不成熟，采用樹脂砂芯或水玻璃砂芯才能鑄造內(nèi)腔復雜鑄件； </p> <p> 真空系統(tǒng)需隨時與砂型相連； </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，尤其低碳鋼件有較嚴重的增碳。南通先進V法鑄造設備V法鑄造中多采用干式真空泵和水環(huán)真空泵，我國主要采用水環(huán)式真空泵。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

通過工藝試驗過程的開展，理解耐磨鑄件V法鑄造工藝路線，熟知工藝控制要點及比較好工藝參數(shù)，對于V法鑄造項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，從單件到小批量，從簡易工藝設備到大型生產(chǎn)線，在充分分析工藝過程的基礎上，對相應V法工藝裝備及生產(chǎn)線有了更充分的認識和風險預判，為后續(xù)的批量化生產(chǎn)奠定了基礎。 </p><p> 4．加砂造型并震實 </p> <p> （1）砂子成分：以120～140目海細沙為宜。 </p> <p> （2）加砂方式：先將少量砂子加到模樣上，壓住薄膜，以保證薄膜不起皺。 </p> <p> （3）砂子處理：用過的砂子要經(jīng)過除塵和冷卻方能使用。 </p> <p> 5．起膜并放置型芯 </p> <p> （1）起膜時要掌握行車，砂箱要平起，盡量避免錯位，錯位要及時修復。 </p> <p> （2）型芯為樹脂砂制作，表面涂油V法涂料。樹脂砂型芯較硬，能保證不粘砂和鑄件的完整。 </p> <p> （3）型芯的位置和尺寸要正確配合型腔 </p> <p> （4）型腔內(nèi)的砂子用真空吸管抽走。 </p> <p> 6．修整型腔并合箱 </p> <p> （1）型腔的拐角、凸緣要補刷涂料以保證能夠鑄出完整。 </p> <p> （2）上線箱體之間放泥條來保證箱體之間的密封。 </p> <p> （3）合箱時要平起平落，不得與芯子相撞。澆注過程還必須保護密封塑料薄膜不被燒掉，否則，將降低鑄型的負壓度及強度。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="揚州質(zhì)量V法鑄造工藝,V法鑄造"

V法鑄造用塑料薄膜厚為0.03～0.25mm。覆膜成型是將塑料薄膜加熱軟化，利用真空將薄膜吸附在凹凸不平的模樣表面上（如圖3.2所示）。由于模樣輪廓結構復雜多樣，要求塑料薄膜具有較好的延伸性，不易產(chǎn)生折痕和破裂。塑料簿膜在模樣或芯盒內(nèi)的成型能力直接影響鑄件的表面光潔度和尺寸精度，因而V法鑄造的薄膜須具有以下要求： </p> <p>

style="text-indent:25px">金屬軟管抽氣和管式抽氣式復合砂箱。在V法鑄造實踐中，針對以上2種砂箱存在的各種問題，國內(nèi)多數(shù)廠家采用復合砂箱，其箱壁用10mm鋼板焊接，用金屬軟管抽氣。砂箱結構簡單，單層壁構成，可制作尺寸較大的砂箱。為避免塌箱引起鑄型沉降和變形，設置較密箱帶。金屬管兩端與固定在砂箱上壁的真空接頭相連，抽氣時，通過軟管的各活動節(jié)的縫隙來抽吸砂粒間的空氣，同時又能阻止細砂及粉塵被吸走。因軟管間隙較大易吸人砂粒和粉塵，真空管路系統(tǒng)必須配有濾砂和水浴裝置。揚州質(zhì)量V法鑄造工藝</p><p
