style="text-indent:25px">V法造型過程中，震動(dòng)是獲得高緊實(shí)度砂型的重要環(huán)節(jié)。V法鑄型的硬度和強(qiáng)度，不*與我們常規(guī)理解中的砂箱的真空度有關(guān)系，震實(shí)效果也是很重要的一方面（如圖4所示）。在震實(shí)不夠的情況下，有時(shí)候通過高的真空度，可以獲得較高的鑄型硬度，但這只是一種假象，砂型強(qiáng)度往往是不足的。在砂型抽真空，翻轉(zhuǎn)，轉(zhuǎn)運(yùn)，合箱，澆注等過程中產(chǎn)生的波動(dòng)又會(huì)造成鑄型內(nèi)砂子形位的重新排布進(jìn)而引起鑄型強(qiáng)度，結(jié)構(gòu)尺寸等的變化。而這些變化反映到鑄件上，則表現(xiàn)出鑄件尺寸或者重量精度超差等質(zhì)量問題。目前在震實(shí)臺設(shè)計(jì)中，對于振幅，震動(dòng)頻率，激振力及如何配置振動(dòng)電機(jī)等問題往往模棱兩可，缺乏基本的核算依據(jù)。揚(yáng)州真空密封V法鑄造生產(chǎn)線利用短流程工藝來澆注V法鑄造中的特大件如大型配重等也引起了越來越多人的濃厚興趣。</p><div

砂芯的設(shè)計(jì)主要是排氣問題，在砂芯的分芯面上開挖排氣和集氣通道，在這些通道上扎制砂芯內(nèi)部排氣孔，再將這些排氣和集氣通道進(jìn)行匯集，通過匯集點(diǎn)向鑄型外排出，使得砂芯內(nèi)氣體有效排出型外，避免氣孔和鑄件內(nèi)壁氧化等缺點(diǎn)。 </p> <p> <br /> </p> <p> <br /> </p> <p> 5.澆注速度、真空保持時(shí)間的設(shè)計(jì) </p> <p> 由于V法鑄造的真空特點(diǎn)，澆注過程中，外型和坭芯均處于真空狀態(tài)，其澆注充型的能力遠(yuǎn)大于其它鑄造工藝。鑒于V法鑄造冷卻緩慢和真空特性，澆注溫度不宜偏高，目的是為了避免或減弱收縮類缺點(diǎn)。 </p> <p> 在通氣和排氣系統(tǒng)適當(dāng)?shù)那闆r下，在澆注末期透氣孔不出現(xiàn)“嗆火”狀態(tài)下可以提高澆注速度，滿足產(chǎn)品質(zhì)量前提下，可以在平常澆注速度的基礎(chǔ)上提高20%～30%;澆注終了的點(diǎn)澆等與其它工藝相同。 </p><p> <p> 生產(chǎn)線的工藝流程 </p> <p> 經(jīng)造型機(jī)造好的鑄型用氣吊將下箱放在合型平臺上進(jìn)行修型和下芯，而后將造好的上箱用氣吊合型并放置在澆注平臺上，澆注后的砂箱經(jīng)氣動(dòng)推桿推至落砂機(jī)上脫砂，人工去除塑料薄膜，落砂后的空砂箱經(jīng)氣缸推送到機(jī)運(yùn)輥道上返回至造型機(jī)旁。鑄件落至桶內(nèi)。舊砂經(jīng)振動(dòng)輸送機(jī)、斗提機(jī)、振動(dòng)篩、水冷流化床等砂處理設(shè)備進(jìn)入料斗貯存，當(dāng)造型需用砂時(shí)，舊砂經(jīng)斗提機(jī)、螺旋輸送機(jī)送入造型機(jī)砂斗里，全線各揚(yáng)塵點(diǎn)均有吸塵管道集中除塵。主機(jī)為四工位造型機(jī)，完成覆膜、噴刷涂料及放砂箱、加砂緊實(shí)和蓋膜，頂箱起模四個(gè)工位，該機(jī)由氣缸驅(qū)動(dòng)旋轉(zhuǎn)，并有可靠的定位機(jī)構(gòu)，自動(dòng)覆膜機(jī)包括自動(dòng)切膜、覆膜框水平移動(dòng)機(jī)構(gòu)，電加熱薄膜、氣動(dòng)頂型覆膜，抽真空閥及覆膜框復(fù)位等功能。四工位造型機(jī)上設(shè)有回轉(zhuǎn)式真空分配閥，跟各工位的要求自動(dòng)提供或切斷真空。整機(jī)動(dòng)作由PLC程序控制。八工位澆注轉(zhuǎn)臺及環(huán)形真空裝置。在小車上裝有8個(gè)砂箱托板組成澆注轉(zhuǎn)臺，驅(qū)動(dòng)機(jī)構(gòu)使轉(zhuǎn)臺回轉(zhuǎn)并可任意位置停機(jī)。動(dòng)作程序是將合型后的砂箱用氣吊放置澆注轉(zhuǎn)臺的托板上，待托板放滿砂箱后便可澆注，轉(zhuǎn)臺每轉(zhuǎn)一個(gè)工位砂箱必須正對著落砂機(jī)，以便氣缸推動(dòng)砂箱至落砂機(jī)的框架上脫砂、落砂前必須撤出負(fù)壓。
