style="text-indent:25px">美國(guó)耐磨狼公司，作為北美地區(qū)礦山耐磨行業(yè)耐磨鑄件的主要供應(yīng)商，采用V法鑄造生產(chǎn)線生產(chǎn)耐磨鑄件，獲得了優(yōu)異的產(chǎn)品質(zhì)量，并將V法鑄造工藝發(fā)展成為了耐磨件鑄造的主流工藝。該公司從1979年開始接觸V法鑄造工藝，共有三條V法鑄造生產(chǎn)線，產(chǎn)品重量在225kg-4500kg之間，單條生產(chǎn)線生產(chǎn)效率比較高達(dá)15箱/小時(shí)。該公司同時(shí)擁有自硬砂鑄造工藝，針對(duì)不同要求產(chǎn)品進(jìn)行不同工藝的搭配生產(chǎn)，其中V法鑄造生產(chǎn)了超過75%的鑄件。該公司認(rèn)為V法鑄造主要有如下優(yōu)勢(shì)：鑄件的一致性好，客戶對(duì)鑄件尤其是大型鑄件一致性的要求更高；環(huán)境友好，生產(chǎn)過程無化學(xué)添加劑，作業(yè)環(huán)境優(yōu)化，無需混砂；更好的鑄件質(zhì)量，鑄件尺寸精度非常出色，鑄件表面質(zhì)量更好；無拔模斜度。</p><p 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(dòng)化程度更高的機(jī)械手完成起模動(dòng)作（見圖7）。相比之前的行車起模和簡(jiǎn)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)。水環(huán)式真空泵依靠水環(huán)實(shí)現(xiàn)密封，各部件的公差較大，不怕干砂粉塵。</p><div
