鍛造鍛件(jian)時退火的種類？

去應力(li)退(tui)火(huo)：為去除鍛件(jian)塑性變形加工(gong)、切削加工(gong)或焊接造成(cheng)的(de)內(nei)應力(li)及(ji)鑄(zhu)件(jian)內(nei)存在(zai)的(de)殘留應力(li)而進行的(de)退(tui)火(huo)。

鍛件(jian)(jian)(jian)中(zhong)存在的內(nei)應力(li)十分有害，如(ru)不及(ji)(ji)時消(xiao)(xiao)除(chu)，將(jiang)使鍛件(jian)(jian)(jian)在加工(gong)(gong)及(ji)(ji)使用(yong)過程(cheng)中(zhong)發生(sheng)變形，影響鍛件(jian)(jian)(jian)精度。此外(wai)，內(nei)應力(li)與外(wai)加載(zai)荷疊(die)加在一起還會(hui)引起材料發生(sheng)意(yi)外(wai)的斷裂。因此，鍛造、鑄造、焊接以及(ji)(ji)切(qie)削加工(gong)(gong)后(hou)的鍛件(jian)(jian)(jian)應采(cai)用(yong)去應力(li)退(tui)火(huo)，以消(xiao)(xiao)除(chu)加工(gong)(gong)過程(cheng)中(zhong)產生(sheng)的內(nei)應力(li)。

去應(ying)力退(tui)火的加(jia)熱溫(wen)(wen)度(du)低(di)于相變溫(wen)(wen)度(du)小，因此在整個處理過(guo)程中不發(fa)生組織(zhi)轉變。內應(ying)力主要是(shi)通過(guo)鍛件(jian)(jian)在保溫(wen)(wen)和緩(huan)冷過(guo)程中消除的。為(wei)了使鍛件(jian)(jian)內應(ying)力消除得更加(jia)，在加(jia)熱時應(ying)控制加(jia)熱速(su)度(du)，一(yi)般是(shi)低(di)溫(wen)(wen)進(jin)爐(lu)，然后以100℃/h左(zuo)右的加(jia)熱速(su)度(du)加(jia)熱到規定(ding)溫(wen)(wen)度(du)焊件(jian)(jian)的加(jia)熱溫(wen)(wen)度(du)略高(gao)于600℃，保溫(wen)(wen)時間(jian)視情況而定(ding)，通常為(wei)2~8h。鑄件(jian)(jian)去應(ying)力退(tui)火的保溫(wen)(wen)時間(jian)宜取上限，冷卻速(su)度(du)控制在20~50℃/h，冷至300℃以下才能出爐(lu)。

筒(tong)類(lei)鍛件產生質量問(wen)題的原因？

筒身(shen)內(nei)外表(biao)面(mian)出現凹坑(keng)的(de)原因是：鍛件在爐內(nei)長時間(jian)高(gao)溫加熱(re)，自(zi)身(shen)產生較厚的(de)氧化(hua)鐵皮(pi)(pi)(pi)，鍛造(zao)(zao)前(qian)沒有用合適的(de)方法完全(quan)清除氧化(hua)皮(pi)(pi)(pi)，鍛造(zao)(zao)過程中將較厚的(de)氧化(hua)皮(pi)(pi)(pi)壓人鍛件本體(ti)造(zao)(zao)成(cheng)凹坑(keng)；坯料(liao)與加熱(re)爐墊鐵上的(de)氧化(hua)皮(pi)(pi)(pi)粘連，鍛造(zao)(zao)前(qian)同樣是由于(yu)沒有用合適的(de)方法去除，導致氧化(hua)皮(pi)(pi)(pi)壓入鍛件本體(ti)。

內外表面產生(sheng)折傷主(zhu)要是(shi)由于鍛造過程中(zhong)錘與錘的搭(da)接量以及壓下量存(cun)在問題所致。

鍛件(jian)出現長(chang)短面主(zhu)要存在于有(you)拔長(chang)工序的筒(tong)節(jie)。長(chang)短面的產生主(zhu)要有(you)以(yi)下(xia)兩(liang)方面原(yuan)因：由(you)于料溫不均，在芯(xin)棒拔長(chang)過(guo)程(cheng)中(zhong)溫度高的地(di)(di)方比溫度低的地(di)(di)方走料快而造成端面長(chang)短不齊；坯料在芯(xin)棒拔長(chang)過(guo)程(cheng)中(zhong)旋轉(zhuan)角度太大造成漏錘(chui)，再加(jia)上每一錘(chui) 的壓下(xia)量不同，導致(zhi)產生長(chang)短面。

大(da)(da)家(jia)好本期小編給(gei)大(da)(da)家(jia)帶來新(xin)的(de)內容，希(xi)望對(dui)大(da)(da)家(jia)有所幫助：鍛件定(ding)制加工

鍛件模具的涂鍍層技術的種類很(hen)多，用于提高模具壽(shou)命(ming)的工(gong)(gong)(gong)藝方法主要有(you)電(dian)(dian)化學沉積(電(dian)(dian)鍍)工(gong)(gong)(gong)藝和熱噴涂工(gong)(gong)(gong)藝。

電(dian)化學沉積(電(dian)鍍)工藝

電(dian)(dian)化學沉(chen)(chen)積工(gong)藝(yi)是用(yong)(yong)電(dian)(dian)化學方法(fa)在(zai)(zai)(zai)金屬或(huo)非(fei)金屬工(gong)件表面(mian)沉(chen)(chen)積一層(ceng)(ceng)或(huo)多(duo)層(ceng)(ceng)金屬鍍(du)(du)層(ceng)(ceng)、合(he)金 鍍(du)(du)層(ceng)(ceng)或(huo)復(fu)合(he)鍍(du)(du)層(ceng)(ceng)的(de)技術。通常(chang)，具(ju)有導電(dian)(dian)能(neng)力的(de)工(gong)件(模具(ju)模膛)放置(zhi)在(zai)(zai)(zai)電(dian)(dian)解質(zhi)中(zhong)，接陰(yin)極(ji)，在(zai)(zai)(zai)外 加電(dian)(dian)流作用(yong)(yong)下，溶液中(zhong)的(de)金屬離子或(huo)Cr離子在(zai)(zai)(zai)工(gong)件(陰(yin)極(ji))表面(mian)發生(sheng)還原(yuan)反應，使金屬沉(chen)(chen)積在(zai)(zai)(zai)工(gong) 件(模具(ju)模膛)表面(mian)。這一過(guo)程又叫電(dian)(dian)沉(chen)(chen)積，俗稱電(dian)(dian)鍍(du)(du)。

電(dian)鍍(du)(du)作(zuo)為(wei)表(biao)面(mian)強化技(ji)術在模(mo)具(ju)(ju)上(shang)的(de)應用(yong) 首推鍍(du)(du)餡(xian)層(ceng)(ceng)，它(ta)具(ju)(ju)有(you)耐磨、減磨、耐熱、耐腐蝕和(he)低摩(mo)擦系(xi)數等(deng)優點。鍍(du)(du)硬餡(xian)層(ceng)(ceng)既可以(yi)作(zuo)為(wei)模(mo)具(ju)(ju)的(de) 耐磨層(ceng)(ceng)，又可以(yi)用(yong)于(yu)(yu)模(mo)具(ju)(ju)修復。由于(yu)(yu)電(dian)鍍(du)(du)層(ceng)(ceng)與模(mo)具(ju)(ju)鋼(gang)的(de)線膨脹系(xi)數差異(yi)較大和(he)與基體(ti)金屬(shu)結合 力(li)的(de)限制，不能用(yong)于(yu)(yu)急冷、急熱的(de)熱作(zuo)模(mo)具(ju)(ju)，一般可用(yong)于(yu)(yu)受力(li)較小的(de)冷作(zuo)模(mo)具(ju)(ju)。此(ci)外，電(dian)刷(shua)鍍(du)(du)Co- N、C。- Mo鍍(du)(du)層(ceng)(ceng)、化學鍍(du)(du)Ni-P鍍(du)(du)層(ceng)(ceng)、Ni-SiC、Ni-B彌(mi)散鍍(du)(du)層(ceng)(ceng)，用(yong)于(yu)(yu)模(mo)具(ju)(ju)表(biao)面(mian)都有(you)提高模(mo)具(ju)(ju)壽(shou)命的(de)作(zuo)用(yong)。
