style="text-indent:25px">低壓鑄造是將鑄型放在一個密閉的爐子上面，型腔的下面用一個管(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，未凝固的金屬從升液管中流回到爐中?？刂屏魅霠t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的金屬型內(nèi)，通過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)晶過程中產(chǎn)生一定量的塑性變形。擠壓鑄造充型平穩(wěn)，沒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，需要銑削加工來完成輪輻的造型。</p><p> 選用氮化硼、碳化硅、陶瓷等耐高溫、耐腐蝕材料制作。升液管本體a和升液管本體b的接縫處設(shè)置3mm的密封墊圈，以保證二者之間嚴(yán)實(shí)密封，防止升液管漏氣。升液管本體a和升液管本體b的接縫處設(shè)置過濾片，升液管本體b的下端設(shè)置第二過濾片，以攔截鋁液中的氧化膜等雜質(zhì);過濾片、第二過濾片的厚度為5mm。[0007]升液管本體b的內(nèi)壁截面呈“正錐型”，錐角5-8°，開口逐漸縮小，通過逐漸加快鋁液的上升速度，以更好的實(shí)現(xiàn)鋁液的撇渣凈化。[0008]升液管本體a的內(nèi)壁截面呈“直線+倒錐型”，錐角5-10°，內(nèi)徑先恒定后逐漸變大，這樣可以使由下端上來的鋁液流速減緩，從而更加平穩(wěn)的進(jìn)入模具型腔。本發(fā)明升液管內(nèi)壁上需涂覆耐高溫、耐金屬液腐蝕的保護(hù)涂層，以加強(qiáng)保溫性能并提尚使用壽命。本實(shí)用新型結(jié)構(gòu)簡單，具有良好的保溫性、較強(qiáng)的撇渣過濾能力，可以使進(jìn)入模具型腔的鋁液更加純凈、質(zhì)量，減少了因鑄件表面出現(xiàn)夾渣而導(dǎo)致廢品的概率，明顯提升了車輪的成形質(zhì)量及合格率，同時降低了企業(yè)的制造成本，更有利于實(shí)現(xiàn)車輪的精細(xì)化生產(chǎn)。1.升液管，包括升液管本體、連接螺栓、定位圓銷、密封墊、過濾片，其特征在于:升液管本體包括升液管本體a(2)、升液管本體b。我公司生產(chǎn)的產(chǎn)品、設(shè)備用途非常多。</p><div
