style="text-indent:25px">鍛造設(shè)備的選擇原則：鍛造液壓機(jī)分為自由鍛液壓機(jī)、模鍛液壓機(jī)和擠壓液壓機(jī)三種。自由鍛液壓機(jī)還有普通自由鍛液壓機(jī)和快速鍛造液壓機(jī)之分。自由鍛液壓機(jī)（3MN～160MN）主要用于各種材料鑄錠開(kāi)坯及大型和特大型自由鍛件的生產(chǎn)?？焖馘懺煲簤簷C(jī)（工作行程速度可達(dá)0.3m/s）一般噸位較小，主要用于特種合金鑄錠開(kāi)坯和制坯。模鍛液壓機(jī)的公稱(chēng)載荷多在8MN～750MN范圍內(nèi)。與其他模鍛設(shè)備相比，模鍛液壓機(jī)工作速度低（工作行程速度在0.1m/s左右或更低）、可控、動(dòng)作平穩(wěn)。鍛造設(shè)備在工作中的作用力是很大的，如曲柄壓力機(jī)、拉伸鍛壓機(jī)和水壓機(jī)這類(lèi)鍛壓設(shè)備。</p><div

style="text-indent:25px">精鍛方面。精密鍛造技術(shù)與機(jī)械加工相比，冷鍛件、精鍛件可明顯降低成本、節(jié)約原材料。我國(guó)鍛造設(shè)備的現(xiàn)狀：一些發(fā)達(dá)國(guó)家都在大力發(fā)展精密鍛造技術(shù)。據(jù)統(tǒng)計(jì)，發(fā)達(dá)國(guó)家鍛造設(shè)備可以生產(chǎn)質(zhì)量公差小于±1%的轎車(chē)精密連桿，對(duì)通常只有8kg的連桿而言，這就意味著鍛件厚度差必須控制在±0.1mm以?xún)?nèi)，這對(duì)鍛造設(shè)備的要求非常高；而我國(guó)一般只能達(dá)到±2%～±3%的厚度差；發(fā)達(dá)國(guó)家大量轎車(chē)零件在**的大型冷、溫鍛壓力機(jī)上實(shí)現(xiàn)冷鍛、溫鍛（每輛轎車(chē)約有50kg的冷鍛件），鍛件直徑方向上的精度可達(dá)0.02mm、同心度不大于0.05mm。零件機(jī)加工余量*留0.3mm的磨削量，真正實(shí)現(xiàn)了凈形加工。發(fā)達(dá)國(guó)家，精鍛技術(shù)已在汽車(chē)制造行業(yè)得到了普遍的應(yīng)用，取得了較好的技術(shù)經(jīng)濟(jì)效益。但是我國(guó)由于缺少大型冷鍛、溫鍛設(shè)備，以及模具壽命較低等條件的限制，溫鍛件與冷鍛件占比偏小。由于它的較高速度一般不高于1.2m/s，并可以進(jìn)行不同變形程度的反復(fù)打擊，因而用途廣。廣州鍛造生產(chǎn)線(xiàn)報(bào)價(jià)</p><p

style="text-indent:25px">鈦合金自由鍛造設(shè)備的選擇：液壓機(jī)按照鍛造速度分為普鍛機(jī)和快鍛機(jī)。由于鈦合金的鍛造溫度區(qū)間很窄，加之隨著現(xiàn)代工業(yè)的快速發(fā)展，人們對(duì)自由鍛件的尺寸精度和生產(chǎn)效率提出了越來(lái)越高的要求，因而對(duì)液壓機(jī)的鍛造速度和壓下精度的要求也隨之提高，為了適應(yīng)這種要求，快鍛液壓機(jī)應(yīng)運(yùn)而生。快鍛機(jī)的液壓系統(tǒng)采用具有快速反應(yīng)的電磁閥作先導(dǎo)閥，其切換頻率高達(dá)250次/min，故該閥動(dòng)態(tài)響應(yīng)快、動(dòng)作靈敏、啟閉迅速，能滿(mǎn)足壓機(jī)快速性要求。在20世紀(jì)80年代中期，由西安重型機(jī)械研究所和北京重型機(jī)械廠(chǎng)研制成國(guó)內(nèi)第1臺(tái)800t快鍛液壓機(jī)組，在蘭石公司投入運(yùn)行。目前，已能生產(chǎn)800t、1600t、2000t、4500t快鍛液壓機(jī)，制造水平有了很大提高，但其液壓系統(tǒng)的主要部件如泵、先導(dǎo)閥等還需國(guó)外配套。我國(guó)快鍛液壓機(jī)的總體水平與德國(guó)等發(fā)達(dá)國(guó)家的制造技術(shù)相比還有較大的差距。由于快鍛機(jī)相比普鍛機(jī)，具有自動(dòng)化程度高、運(yùn)行速度快、可控制壓下量、節(jié)能節(jié)材效果明顯等特點(diǎn)，使工作效率更高，提高了鍛件外觀(guān)質(zhì)量和組織性能、減少了操作人員。因此目前鈦合金的自由鍛造設(shè)備主要使用快鍛機(jī)。東莞汽車(chē)半軸擺輾機(jī)價(jià)格</p></p><br
