環(huan)形鍛件(jian)的輾(zhan)擴工藝有哪幾類？

按輾(zhan)擴過程中環(huan)形件受壓(ya)變形方(fang)向(xiang)不(bu)同可分為徑向(xiang)輾(zhan)擴與(yu)徑向(xiang)和軸向(xiang)輾(zhan)擴兩種方(fang)式。

(1)徑向(xiang)(xiang)輾擴。在輾擴過程中，環(huan)壁徑向(xiang)(xiang)受壓(ya)縮，金屬沿(yan)切(qie)線方向(xiang)(xiang)延伸。而(er)軸向(xiang)(xiang)即使不受軋(ya)輥限(xian)制，環(huan)壁的(de)寬展量仍(reng)然很小。徑向(xiang)(xiang)輾擴工(gong)藝(yi)(yi)主要(yao)適用(yong)于矩形截(jie)(jie)面(mian)、溝(gou)槽(cao)形截(jie)(jie)面(mian)、十宇形截(jie)(jie)面(mian)環(huan)件(jian)，這種(zhong)工(gong)藝(yi)(yi)所用(yong)的(de)設備簡單且造價成(cheng)本低，因此這種(zhong)設備在擴孔工(gong)藝(yi)(yi)中被廣泛使用(yong)。一般換件(jian)外徑1000mm以內的(de)采用(yong)立(li)式(shi)結(jie)構，而(er)大(da)于1000mm的(de)換件(jian)采用(yong)臥(wo)式(shi)結(jie)構

(2)徑向(xiang)(xiang)(xiang)和軸向(xiang)(xiang)(xiang)輾(zhan)擴。徑向(xiang)(xiang)(xiang)是在徑向(xiang)(xiang)(xiang)輾(zhan)擴的(de)基礎上(shang)，加端面(mian)軋(ya)輥(gun)，使其產生軸向(xiang)(xiang)(xiang)變形(xing)的(de)環(huan)(huan)軋(ya)工(gong)藝。它用一對徑向(xiang)(xiang)(xiang)軋(ya)輥(gun)和一對軸向(xiang)(xiang)(xiang)軋(ya)輥(gun)來分別軋(ya)制(zhi)環(huan)(huan)的(de)壁厚和環(huan)(huan)的(de)高度，軋(ya)制(zhi)的(de)圓環(huan)(huan)具有平直的(de)端面(mian)，模具更(geng)換的(de)次數少，因此大(da)大(da)節省(sheng)了模具。這(zhe)種工(gong)藝主要適用于(yu)壁厚較大(da)或栽(zai)面(mian)較復雜的(de)環(huan)(huan)形(xing)鍛件(jian)。

由于熱(re)(re)(re)處(chu)(chu)理(li)(li)過程中(zhong)(zhong)存在相變和(he)熱(re)(re)(re)應力，因(yin)此熱(re)(re)(re)處(chu)(chu)理(li)(li)變形總是不可(ke)避免(mian)的(de)(de)(de)。一定量(liang)微小(xiao)變形是允許的(de)(de)(de)，但總變形超(chao)過限度就成為熱(re)(re)(re)處(chu)(chu)理(li)(li)缺(que)陷(xian)。熱(re)(re)(re)處(chu)(chu)理(li)(li)缺(que)陷(xian)中(zhong)(zhong)危險的(de)(de)(de)是裂(lie)紋，它(ta)屬于不可(ke)挽救的(de)(de)(de)缺(que)陷(xian)，一般只能(neng)將裂(lie)紋鍛件報廢(fei)處(chu)(chu)理(li)(li)。所(suo)以，在熱(re)(re)(re)處(chu)(chu)理(li)(li)生產中(zhong)(zhong)，應盡量(liang)減少(shao)變形，并(bing)且特(te)別注意避免(mian)產生裂(lie)紋。

鍛件的試驗(yan)方(fang)法有(you)哪些？

復試

若(ruo)由于試驗(yan)設備(bei)故障，或試樣(yang)制(zhi)備(bei)不正確，以(yi)及與材料無關的(de)傷痕，致使某一試樣(yang)的(de)性(xing)能(neng)值(zhi)未能(neng)滿足規定的(de)要求，則該(gai)試驗(yan)廢棄，可在鍛(duan)件中(zhong)該(gai)試樣(yang)的(de)相鄰位置重新取樣(yang)試驗(yan)。

拉伸試(shi)驗時(shi)，若試(shi)樣在(zai)(zai)標(biao)(biao)距(ju)外或在(zai)(zai)標(biao)(biao)距(ju)中(zhong)心到標(biao)(biao)距(ju)點的距(ju)離的1/2以外處斷裂，且試(shi)驗結(jie)果又(you)不符合規定要求時(shi)，則(ze)該(gai)試(shi)樣無(wu)效(xiao)，可(ke)在(zai)(zai)鍛件中(zhong)該(gai)試(shi)樣的相鄰位置重新取樣試(shi)驗。

若試(shi)樣不是由(you)于鍛(duan)件中白點或裂紋等原因，而未(wei)能滿(man)足規定的要求(qiu)，則鍛(duan)件可不經重(zhong)新熱處理，在該試(shi)樣的相鄰(lin)位(wei)置取雙倍(bei)試(shi)樣復試(shi)，此(ci)兩試(shi)樣均應(ying)滿(man)足規定的要求(qiu)。

若(ruo)鍛件的強度性(xing)(xing)能(neng)指(zhi)標較(jiao)高，但(dan)塑性(xing)(xing)、韌性(xing)(xing)指(zhi)標未(wei)能(neng)滿足規定(ding)的要求時，可對鍛件進(jin)行補(bu)充(chong)回(hui)火(huo)，補(bu)充(chong)回(hui)火(huo)的次數不作(zuo)限制。回(hui)火(huo)后按原規定(ding)進(jin)行試(shi)驗。

若鍛(duan)件的(de)力學性(xing)能試驗結果未(wei)能符合規定(ding)的(de)要求，制造(zao)廠可對鍛(duan)件進行重新熱(re)處(chu)理(li)，按(an)原(yuan)規定(ding)進行試驗。未(wei)經需方許可，重新熱(re)處(chu)理(li)次數(shu)不得超過2次。

鍛(duan)件模具的涂鍍層技術的種類(lei)很多(duo)，用于提高模具壽命的工(gong)藝方法(fa)主要有電(dian)化學沉積(ji)(電(dian)鍍)工(gong)藝和熱噴涂工(gong)藝。

電(dian)化學沉積(電(dian)鍍)工藝

電(dian)化(hua)學沉(chen)積工(gong)藝是用(yong)電(dian)化(hua)學方法在(zai)金(jin)(jin)屬(shu)(shu)或(huo)非(fei)金(jin)(jin)屬(shu)(shu)工(gong)件(jian)表(biao)面(mian)沉(chen)積一層(ceng)或(huo)多層(ceng)金(jin)(jin)屬(shu)(shu)鍍(du)層(ceng)、合(he)金(jin)(jin) 鍍(du)層(ceng)或(huo)復合(he)鍍(du)層(ceng)的(de)(de)技(ji)術。通常，具有導電(dian)能(neng)力的(de)(de)工(gong)件(jian)(模(mo)具模(mo)膛)放(fang)置在(zai)電(dian)解質中(zhong)，接陰極(ji)，在(zai)外(wai) 加電(dian)流作用(yong)下，溶液中(zhong)的(de)(de)金(jin)(jin)屬(shu)(shu)離(li)(li)子(zi)或(huo)Cr離(li)(li)子(zi)在(zai)工(gong)件(jian)(陰極(ji))表(biao)面(mian)發(fa)生還原反應(ying)，使金(jin)(jin)屬(shu)(shu)沉(chen)積在(zai)工(gong) 件(jian)(模(mo)具模(mo)膛)表(biao)面(mian)。這一過程又叫電(dian)沉(chen)積，俗(su)稱電(dian)鍍(du)。

電鍍(du)作(zuo)為表(biao)面強化技術在模具(ju)(ju)上(shang)的應(ying)用(yong)(yong) 首推鍍(du)餡(xian)層，它具(ju)(ju)有(you)耐磨、減磨、耐熱、耐腐蝕和(he)低摩擦系數等(deng)優點。鍍(du)硬餡(xian)層既(ji)可(ke)以作(zuo)為模具(ju)(ju)的 耐磨層，又可(ke)以用(yong)(yong)于(yu)模具(ju)(ju)修復。由于(yu)電鍍(du)層與(yu)模具(ju)(ju)鋼(gang)的線(xian)膨脹系數差異較(jiao)大和(he)與(yu)基體金(jin)屬結合 力的限制，不(bu)能用(yong)(yong)于(yu)急冷、急熱的熱作(zuo)模具(ju)(ju)，一般可(ke)用(yong)(yong)于(yu)受力較(jiao)小的冷作(zuo)模具(ju)(ju)。此(ci)外，電刷鍍(du)Co- N、C。- Mo鍍(du)層、化學鍍(du)Ni-P鍍(du)層、Ni-SiC、Ni-B彌散鍍(du)層，用(yong)(yong)于(yu)模具(ju)(ju)表(biao)面都有(you)提高模具(ju)(ju)壽命的作(zuo)用(yong)(yong)。
