1、單向壓制單向壓制工作原理：陰模型腔和下模沖的位置固定不動(dòng)，上模沖在壓機(jī)凸輪帶動(dòng)下，向下進(jìn)入陰模型腔，并對(duì)陰模型腔的粉末加壓，使粉末壓制成具有一定密度和強(qiáng)度的坯件。 </p> <p> 單向壓制的一個(gè)循環(huán)有以下步驟：A粉末充填：粉末通過(guò)手工或者動(dòng)送粉器的送粉，利用粉末重力充填在陰模型腔中。B單向壓制：粉末填充完畢后，陰模型腔與下模沖位置固定不變，上模沖在壓機(jī)凸輪帶動(dòng)下，向下進(jìn)入陰模型腔，使粉末壓制成成具有一定密度和強(qiáng)度的坯件。C保壓：為了使壓力得到有效傳遞，使坯件密度分布均勻，上模沖應(yīng)在180度的成型壓制位置下保持不動(dòng)一段時(shí)間，使坯件中空氣有足夠時(shí)間逸出。D脫模：保壓結(jié)束后，上模沖由壓機(jī)凸輪復(fù)位帶動(dòng)向上脫離陰模型腔，下模沖則由壓機(jī)的下氣缸的作用力作用下把坯件頂出陰模型腔。E復(fù)位：上模沖退到高點(diǎn)，送粉器把壓制的坯件推出，同時(shí)下模沖退回固定位置，同時(shí)粉末在重力作用下充填在陰模型腔中。舟山軸承粉末冶金粉末冶金的應(yīng)用領(lǐng)域：考慮到車(chē)輛節(jié)能、輕量化及產(chǎn)品精度化的訴求。</p><div

在粉末冶金領(lǐng)域，用純銅粉生產(chǎn)電子和導(dǎo)熱零部件。含有錫、鋅、鎳、或者鐵的銅合金被寬泛用于汽車(chē)、草地公園設(shè)備、工具和電子工業(yè)。銅粉多使用在自潤(rùn)滑軸承上，另外是Fe-Cu預(yù)混合，化學(xué)工業(yè)領(lǐng)域的滲析和摩擦材料部件。 </p> <p> 粉末冶金含油軸承一般來(lái)說(shuō)一次就能成形，基本不用切削加工。成本比機(jī)加工輕，材料浪費(fèi)也少，價(jià)格因此比較便宜。也符合現(xiàn)在提倡節(jié)約能源的國(guó)家政策,因此被認(rèn)為這是一個(gè)不會(huì)落伍的技術(shù)。粉末冶金含油軸承其基體里已經(jīng)用真空含浸的方法充滿(mǎn)了潤(rùn)滑油，并且在運(yùn)轉(zhuǎn)時(shí)由于溫升和泵吸的原因，其中的潤(rùn)滑油會(huì)滲出到運(yùn)轉(zhuǎn)表面，故可用于不另加潤(rùn)滑油的場(chǎng)合。粉末冶金含油軸承(含油軸承)是一類(lèi)孔隙中含浸有潤(rùn)滑油的多孔性合金制品。當(dāng)軸旋轉(zhuǎn)時(shí)，因軸與含油軸承之間的摩擦使含油軸承的溫度升高和泵吸作用。 </p><p> 在粉末冶金材料的熱處理中，為了提高淬透性，通常加入一些合金元素如：鎳、鉬、錳、鉻、釩等，它們的作用跟在致密材料中的作用機(jī)理相同，可明顯細(xì)化晶粒，當(dāng)其溶于奧氏體后會(huì)增加過(guò)冷奧氏體的穩(wěn)定性，保證淬火時(shí)的奧氏體轉(zhuǎn)變，使淬火后材料的表面硬度增加，淬硬深度也增加。另外，粉末冶金材料淬火后都要進(jìn)行回火處理，回火處理的溫度控制對(duì)粉末冶金材料的的性能影響較大，因此要根據(jù)不同材料的特性確定回火溫度，降低回火脆性的影響，一般的材料可在175-250℃下空氣或油中回火0.5-1.0h。 </p> <p> 2、化學(xué)熱處理工藝 </p> <p> 化學(xué)熱處理一般都包括分解、吸收、擴(kuò)散三個(gè)基本過(guò)程，比如，滲碳熱處理的反應(yīng)如下： </p> <p> 2CO≒[C]+CO2 (放熱反應(yīng)) </p> <p> CH4≒[C]+2H2 (吸熱反應(yīng)) 粉末冶金的分類(lèi)有哪幾個(gè)大類(lèi)呢？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="北侖粉末冶金技術(shù),粉末冶金"

綜合來(lái)看，粉末冶金產(chǎn)品是伴隨著下游需求和冶金技術(shù)不斷發(fā)展而發(fā)展起來(lái)的。就應(yīng)用領(lǐng)域分類(lèi)，其不僅可以應(yīng)用在傳統(tǒng)的如機(jī)械加工、鉆探、電器、機(jī)械汽車(chē)等傳統(tǒng)領(lǐng)域，還可應(yīng)用在諸多如TMT、**、節(jié)能環(huán)保等新興領(lǐng)域。 </p> <p> **人才的緊缺是目前我國(guó)每個(gè)行業(yè)普遍存在的現(xiàn)象，粉末冶金汽車(chē)零部件市場(chǎng)也不例外。粉末冶金汽車(chē)零部件屬于資金、技術(shù)密集型產(chǎn)業(yè)，對(duì)**復(fù)合型技術(shù)人才存在較大需求。粉末冶金汽車(chē)零部件不但要求從業(yè)技術(shù)人員具備扎實(shí)的粉末冶金知識(shí)，而且需要豐富的實(shí)踐工作經(jīng)驗(yàn)，對(duì)粉末冶金汽車(chē)零部件有深刻認(rèn)識(shí);除此之外，還需要擁有較強(qiáng)的技術(shù)綜合運(yùn)用能力、良好的團(tuán)隊(duì)意識(shí)和敬業(yè)精神。目前，**技術(shù)人才的缺乏是制約粉末冶金汽車(chē)零部件發(fā)展的瓶頸之一。粉末冶金制品的電鍍處理，目前流行的辦法是將多孔的粉末冶金零件例如粉末制品用樹(shù)脂。宿遷粉末冶金成型機(jī)</p><p
