style="text-indent:25px">V法鑄造是真空密封造型或負(fù)壓造型鑄造工藝的簡(jiǎn)稱，其原理是利用塑料薄膜覆模造型并密封砂箱，依靠真空泵抽出型內(nèi)空氣，造成型內(nèi)箱外壓力差，使干砂緊實(shí)，形成所需型腔。其比較大優(yōu)勢(shì)是型砂不使用粘結(jié)劑，干砂回用率高達(dá)95%以上，不僅節(jié)能環(huán)保、落砂簡(jiǎn)便，揚(yáng)州真空密封V法鑄造工藝、改善勞動(dòng)條件，而且鑄件表面品質(zhì)和尺寸精度**提高。V法鑄造是日本長(zhǎng)野縣工業(yè)試驗(yàn)所和秋田株式會(huì)社于1971年的發(fā)明專利，揚(yáng)州真空密封V法鑄造工藝。V法鑄造至今經(jīng)過了38年的發(fā)展，同消失模鑄造一樣，作為第3代造型方法即物理硬化方法，在世界上尤其是在中國(guó)獲得了長(zhǎng)足的發(fā)展，揚(yáng)州真空密封V法鑄造工藝。V法鑄造中多采用干式真空泵和水環(huán)真空泵，我國(guó)主要采用水環(huán)式真空泵。揚(yáng)州真空密封V法鑄造工藝</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="揚(yáng)州真空密封V法鑄造工藝,V法鑄造" src="https://tyunfile.71360.com/UploadFile/Jyhuatian/637293889462666016/4862105.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(guó)際鑄造工業(yè)展覽會(huì)鑄件一等獎(jiǎng)。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(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，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。揚(yáng)州真空V法鑄造企業(yè)國(guó)家環(huán)保的壓力更是推動(dòng)了部分不符合標(biāo)準(zhǔn)的小企業(yè)加快了這一實(shí)驗(yàn)的腳步。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="揚(yáng)州真空密封V法鑄造工藝,V法鑄造" src="https://tyunfile.71360.com/UploadFile/Jyhuatian/637293889895390625/1638242.png"></div><p style="text-indent:25px">③金屬軟管抽氣和管式抽氣式復(fù)合砂箱。在V法鑄造實(shí)踐中，針對(duì)以上2種砂箱存在的各種問題，國(guó)內(nèi)多數(shù)廠家采用復(fù)合砂箱，其箱壁用10mm鋼板焊接，用金屬軟管抽氣。砂箱結(jié)構(gòu)簡(jiǎn)單，單層壁構(gòu)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(shè)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(shí)，通過軟管的各活動(dòng)節(jié)的縫隙來(lái)抽吸砂粒間的空氣，同時(shí)又能阻止細(xì)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。</p><p style="text-indent:25px">可借鑒的參考數(shù)據(jù)是，振幅0.5mm左右，頻率不低于1500/min可以達(dá)到比較好的震實(shí)效果。不太理想的是，部分震實(shí)臺(tái)的設(shè)計(jì)參數(shù)并不滿足推薦的經(jīng)驗(yàn)數(shù)據(jù)。而鑄造企業(yè)在使用的過程中則常常發(fā)現(xiàn)，震實(shí)臺(tái)激振力不夠或過強(qiáng)，振幅不足或過大等一系列問題。這就是為什么同樣的鑄件，同樣的砂箱，同樣的模具，在不同的廠家，震實(shí)時(shí)間，震實(shí)效果有差異的原因。更有甚者，震實(shí)臺(tái)振動(dòng)電機(jī)缺乏基本的變頻功能；哪怕具備變頻特性，也不根據(jù)震實(shí)臺(tái)負(fù)載的變化合理調(diào)整頻率，激振力等參數(shù)，以至于震實(shí)臺(tái)發(fā)揮不了應(yīng)有的作用。但澆注時(shí)負(fù)壓度的變化大，澆注瞬間，負(fù)壓度下降快，澆注完畢后鑄型能恢復(fù)并保持較高的負(fù)壓度。</p><div

耐磨鑄造車間的建設(shè)是一個(gè)系統(tǒng)工程，除了生產(chǎn)設(shè)備本身外，車間布局物流設(shè)計(jì)，原輔材料的配套，熱處理系統(tǒng)的配套，機(jī)加工設(shè)備的配套等都要作為系統(tǒng)的一部分考慮。 </p> <p> 以砂箱的周轉(zhuǎn)為例，耐磨鑄件由于保溫冷卻時(shí)間長(zhǎng)，在一定程度上限制了砂箱的流轉(zhuǎn)速度，企業(yè)訂購(gòu)大量砂箱不僅**增加了企業(yè)成本，而且造成管理使用上的困難。可通過采用建設(shè)冷卻立體庫(kù)，設(shè)計(jì)冷卻托盤的方式加快砂箱流轉(zhuǎn)，同時(shí)節(jié)約生產(chǎn)場(chǎng)地。標(biāo)準(zhǔn)化托盤的設(shè)計(jì)和制作，滿足叉車運(yùn)輸條件，并不額外增加過多的勞動(dòng)力，實(shí)現(xiàn)了工藝生產(chǎn)的要求，降低了設(shè)備投資成本，同時(shí)提高的系統(tǒng)運(yùn)行效率。再生的舊砂成套設(shè)備應(yīng)包括落砂，輸送、分選、過篩及砂冷卻系統(tǒng)。南通V法鑄造設(shè)備</p><p

style="text-indent:25px">鑄型強(qiáng)度不夠或者不均勻，在有些具有大平面特點(diǎn)的鑄件生產(chǎn)上，不能很好的減小或防止鑄件在冷卻過程中的變形。有時(shí)候常常為了落砂的簡(jiǎn)易性，對(duì)于下箱往往不加箱檔，以利于鑄件直接從砂箱脫出。這是不合理的。上下箱必須都設(shè)計(jì)抽氣箱檔，才能有效保障鑄型強(qiáng)度的均勻性及上下鑄型強(qiáng)度的對(duì)等性。圖9、圖10為某廠生產(chǎn)某種型號(hào)的鐵路側(cè)架鑄件的上下箱結(jié)構(gòu)圖。另外值得一提的是，砂箱結(jié)構(gòu)設(shè)計(jì)合理，對(duì)于同一套真空系統(tǒng)來(lái)講，可能同時(shí)允許接入的砂箱數(shù)量就會(huì)增加，意味著真空系統(tǒng)的利用效率明顯增強(qiáng)。揚(yáng)州真空密封V法鑄造工藝</p><p
