style="text-indent:25px">鑄造行業(yè)誕生了一種新型的鑄造工藝——V法鑄造。V法鑄造即真空密封造型，原理是利用塑料薄膜密封砂箱，采用真空泵抽出型內(nèi)空氣，在鑄型內(nèi)外形成壓力差，使干砂緊實(shí)，以形成所需型腔。V法鑄造區(qū)別于傳統(tǒng)砂鑄比較大的優(yōu)點(diǎn)是不使用粘合劑，因而減輕了砂處理工作，而且造型和鑄件粘砂清理的勞動(dòng)量也減少，舊砂回收率可達(dá)95%以上。V法鑄造工藝生產(chǎn)出來(lái)的鑄件質(zhì)量好、表面光潔、輪廓清晰、尺寸準(zhǔn)確、硬度均勻，有效延長(zhǎng)了鑄件的使用壽命，受到用戶(hù)贊譽(yù)，成為行業(yè)新寵。</p><p> V法鑄造工藝裝備對(duì)鑄件質(zhì)量的影響 </p> <p> V法鑄造引入我國(guó)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(wú)到有以及由對(duì)外引進(jìn)仿制，到自主研發(fā)設(shè)計(jì)的過(guò)程。V法鑄造裝備質(zhì)量水平的提升，也進(jìn)一步保障并促進(jìn)了V法鑄造工藝的拓展。據(jù)不完全統(tǒng)計(jì)，目前國(guó)內(nèi)約有400多條形式各異的V法鑄造生產(chǎn)線(xiàn)在運(yùn)行，既有極其簡(jiǎn)易甚至不配套砂處理的單機(jī)造型設(shè)備，也有比較常見(jiàn)且配置相對(duì)***的半自動(dòng)鑄造生產(chǎn)線(xiàn)，更有機(jī)械化，自動(dòng)化程度較高，投資規(guī)模龐大的現(xiàn)代化V法鑄造車(chē)間。但是根據(jù)大量的調(diào)研與實(shí)踐，發(fā)現(xiàn)部分設(shè)備和工裝難以滿(mǎn)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(guò)程中覆膜成形，加砂震實(shí)，抽真空起模工序，相應(yīng)設(shè)備工裝的特點(diǎn)明顯影響著鑄型和鑄件質(zhì)量。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(kāi)放式澆注系統(tǒng)。</p><div

src="https://tyunfile.71360.com/UploadFile/Jyhuatian/637293889732578125/1173701.png"></div><p> V法具有與傳統(tǒng)砂型鑄造無(wú)法比擬的優(yōu)勢(shì)，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(wú)磨損，金屬模具壽命長(zhǎng)，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(chē)鑄鐵配重是V法鑄造產(chǎn)品的典型**。安徽合力叉車(chē)集團(tuán)合肥鑄鍛廠生產(chǎn)的叉車(chē)配重，曾獲2002年第四屆北京國(guó)際鑄造工業(yè)展覽會(huì)鑄件一等獎(jiǎng)。世界上叉車(chē)和其他工程車(chē)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(dòng)性。試驗(yàn)表明：V法鑄造和濕型鑄造相比，金屬液流動(dòng)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(jìn)日本新東鑄造生產(chǎn)線(xiàn)，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。鋁合金多采用開(kāi)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%；泰州專(zhuān)業(yè)V法鑄造流程</p><p style="text-indent:25px">模型及砂箱的使用壽命長(zhǎng)，用塑料薄膜保護(hù)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。泰州專(zhuān)業(yè)V法鑄造流程</p><p style="text-indent:25px">V法鑄造工藝生產(chǎn)出的鑄件質(zhì)量好，表面光潔，輪廓清晰，金屬利用率高，設(shè)備投資簡(jiǎn)單易行，硬度均勻，有效地延長(zhǎng)了鑄件的使用壽命，并能有效地改善工作環(huán)境，便于管理和組織生產(chǎn)，該設(shè)備深受用戶(hù)好評(píng)。與傳統(tǒng)砂鑄工藝相比，V法鑄造工藝具有不使用粘結(jié)劑的優(yōu)勢(shì)，V法鑄造采用塑膜密封砂箱，靠真空抽氣系統(tǒng)抽出型材內(nèi)空氣，鑄型內(nèi)外壓差，使干砂致密，形成所需型腔，通過(guò)下芯、合箱、澆注抽真空使鑄件凝固，解除負(fù)壓，型砂隨之潰散而獲得鑄件。泰州專(zhuān)業(yè)V法鑄造流程</p><p
