升液管本實(shí)用新型涉及一種升液管，具體的說(shuō)涉及一種鋁合金車(chē)輪低壓鑄造使用的升液管。由于鋁合金車(chē)輪是汽車(chē)上**為重要的外觀件及**件之一，因此各主機(jī)廠都對(duì)車(chē)輪供貨提出了嚴(yán)格的要求，無(wú)論是尺寸、外觀還是性能均要滿足一定的設(shè)計(jì)標(biāo)準(zhǔn)。目前，世界上約80%的鋁合金車(chē)輪生產(chǎn)采用低壓鑄造成形工藝，該技術(shù)屬于底部中心澆注形式，保溫爐內(nèi)的高溫鋁液通過(guò)升液管道進(jìn)入模具型腔，并在模具及外部冷卻的共同作用下凝固成形，**終得到合格的毛坯鑄件。在整個(gè)鑄造系統(tǒng)中，升液管作為連接保溫爐與模具的通道，在車(chē)輪生產(chǎn)中的作用舉足輕重。依據(jù)生產(chǎn)經(jīng)驗(yàn)，一個(gè)質(zhì)量的升液管應(yīng)該具備以下特點(diǎn):良好的保溫性，比較大限度的減少鋁液在進(jìn)入型腔前的熱量損失，以防止發(fā)生鋁液凍死事情；具備較強(qiáng)的鋁液過(guò)濾能力，不可以將保溫爐內(nèi)的氧化膜等雜質(zhì)帶入模具型腔，形成鑄件夾渣廢品；具有良好的耐腐蝕性、耐高溫性，保證升液管有較長(zhǎng)的使用壽命；價(jià)格經(jīng)濟(jì)，節(jié)約生產(chǎn)成本。然而，現(xiàn)有技術(shù)中的升液管很難兼具上述幾種特質(zhì)，也因此會(huì)造成生產(chǎn)中工藝控制困難，鑄件夾渣缺點(diǎn)頻發(fā)，產(chǎn)品外觀不達(dá)標(biāo)導(dǎo)致客戶抱怨等等問(wèn)題，這些問(wèn)題都嚴(yán)重的制約著車(chē)輪的成品率，并提高了企業(yè)的制造成本。 </p><p style="text-indent:25px">使用中注意因受氮化硅升液管材料自身特性的影響，需在一些方面應(yīng)多加以注意： 1.盡量減輕機(jī)械碰撞，特別是在搬運(yùn)及安裝調(diào)試時(shí)，猛烈的撞擊和不均勻的受力，將**縮短升液管的壽命。 2.盡量減輕機(jī)械震動(dòng)，特別是在熱狀態(tài)下，持續(xù)的受力和震動(dòng)，將**縮短升液管的使用壽命。 3.盡量減輕溫差波動(dòng)，特別是在急促升溫及降溫時(shí)，反復(fù)的熱沖擊將**縮短升液管的使用壽命。另外，機(jī)臺(tái)使用人員的操作水平，經(jīng)驗(yàn)、熟練程度也非常大的影響了升液管的使用壽命。要想延長(zhǎng)升液管的使用壽命，必須在各個(gè)環(huán)節(jié)上都要精心注意，嚴(yán)格把關(guān)持之以恒。奧翔硅碳具備雄厚的實(shí)力和豐富的實(shí)踐經(jīng)驗(yàn)。</p><div

style="text-indent:25px">低壓鑄造是將鑄型放在一個(gè)密閉的爐子上面，型腔的下面用一個(gè)管(叫升液管)和爐膛里的金屬液相通。如果在爐膛中金屬液面上加入帶壓力的空氣，金屬液會(huì)從升液管中流入型腔。待金屬液凝固以后，將爐膛中的壓縮空氣釋放，未凝固的金屬?gòu)纳汗苤辛骰氐綘t中。控制流入爐膛空氣的壓力、速度,就可以控制金屬流入型腔中的速度和壓力，并能讓金屬在壓力下結(jié)晶凝固。這種工藝特點(diǎn)是鑄件在壓力下結(jié)晶，結(jié)構(gòu)致密，機(jī)械性能好，金屬利用率高。擠壓鑄造也稱(chēng)為液態(tài)模鍛，是一種集鑄造和鍛造特點(diǎn)于一體的新工藝，該工藝是將一定量的金屬液體直接澆入敞開(kāi)的金屬型內(nèi)，通過(guò)沖頭以一定的壓力作用于液體金屬上，使之充填、成形和結(jié)晶凝固，并在結(jié)晶過(guò)程中產(chǎn)生一定量的塑性變形。擠壓鑄造充型平穩(wěn)，沒(méi)有湍流和不包卷氣體，金屬直接在壓力下結(jié)晶凝固，所以鑄件不會(huì)產(chǎn)生氣孔、縮孔和縮松等鑄造缺點(diǎn)，且結(jié)構(gòu)致密、晶粒細(xì)化，機(jī)械性能比低壓鑄造件高。產(chǎn)品既有接近鍛件的優(yōu)良機(jī)械性能，又有精鑄件一次精密成形的高效率、高精度，且投資極大低于低壓鑄造法。缺點(diǎn)是液態(tài)模鍛的產(chǎn)品與傳統(tǒng)鍛造產(chǎn)品一樣，需要銑削加工來(lái)完成輪輻的造型。奧翔硅碳重信譽(yù)、守合同，嚴(yán)把產(chǎn)品質(zhì)量關(guān)，熱誠(chéng)歡迎廣大用戶前來(lái)咨詢考察，洽談業(yè)務(wù)！天津高溫升液管廠</p><p
