粉(fen)末冶(ye)金制(zhi)品(pin)應(ying)用已非常(chang)廣泛，但平(ping)時生產過(guo)程中(zhong)仍(reng)會遇到不同程度的(de)問題，下面為大家分享一下的(de)粉(fen)末冶(ye)金制(zhi)品(pin)清(qing)洗(xi)工藝。

由于(yu)(yu)(yu)粉(fen)末冶金自(zi)(zi)身的多(duo)孔性(xing)結構，首當其(qi)沖的就(jiu)是清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)后(hou)的防銹問題。就(jiu)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)介質(zhi)(zhi)(zhi)(zhi)而(er)言(yan)，現階段一般(ban)采用(yong)煤油(you)或(huo)白油(you)，后(hou)者較(jiao)前(qian)者防銹性(xing)能(neng)更佳，但由于(yu)(yu)(yu)張力(li)較(jiao)大(da)，對超聲(sheng)(sheng)波(bo)(bo)功率、密度有(you)一定要(yao)求，普通的超聲(sheng)(sheng)波(bo)(bo)換能(neng)器無法匹配油(you)性(xing)介質(zhi)(zhi)(zhi)(zhi)的零(ling)(ling)件(jian)(jian)(jian)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)要(yao)求。而(er)水(shui)溶(rong)性(xing)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)介質(zhi)(zhi)(zhi)(zhi)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)光亮度佳，但必須增(zeng)添脫水(shui)防銹工序(xu)(xu)，否則日后(hou)零(ling)(ling)件(jian)(jian)(jian)容易(yi)從內而(er)外銹蝕(shi)(shi)，影響成(cheng)(cheng)品(pin)質(zhi)(zhi)(zhi)(zhi)量。此外，目前(qian)市面(mian)(mian)上(shang)已(yi)出現真空(kong)碳氫的超聲(sheng)(sheng)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)設(she)備(bei)，可避免(mian)銹蝕(shi)(shi)的產生，但由于(yu)(yu)(yu)碳氫溶(rong)劑(ji)多(duo)為(wei)(wei)國外進口且易(yi)揮發(fa)，使(shi)用(yong)時需(xu)綜(zong)合(he)計算成(cheng)(cheng)本；就(jiu)設(she)備(bei)結構而(er)言(yan)，市面(mian)(mian)上(shang)普遍為(wei)(wei)機械臂(bei)式(shi)、履帶通過(guo)(guo)式(shi)超聲(sheng)(sheng)波(bo)(bo)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)設(she)備(bei)。兩者均可采用(yong)PLC程(cheng)控預設(she)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)工序(xu)(xu)，但目前(qian)存在清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)工裝(zhuang)設(she)計不(bu)合(he)理(li)(li)、超聲(sheng)(sheng)波(bo)(bo)輻(fu)射面(mian)(mian)過(guo)(guo)寬等問題，從而(er)導致(zhi)不(bu)同位面(mian)(mian)的零(ling)(ling)件(jian)(jian)(jian)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)效(xiao)果不(bu)均，需(xu)人工二(er)次處理(li)(li)。由于(yu)(yu)(yu)粉(fen)末冶金制品(pin)經壓(ya)制、燒(shao)結后(hou)表面(mian)(mian)殘留有(you)大(da)量細(xi)微顆粒(li)(li)，理(li)(li)想的清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)方式(shi)是在聲(sheng)(sheng)波(bo)(bo)輻(fu)射過(guo)(guo)程(cheng)中增(zeng)加拋動工序(xu)(xu)或(huo)保(bao)持零(ling)(ling)件(jian)(jian)(jian)輕(qing)微翻滾，從而(er)有(you)效(xiao)抖(dou)落已(yi)被清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)剝離的顆粒(li)(li)物(wu)；清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)過(guo)(guo)程(cheng)中要(yao)特別注意設(she)備(bei)的保(bao)養(yang)清(qing)(qing)(qing)(qing)(qing)潔(jie)，許多(duo)超聲(sheng)(sheng)設(she)備(bei)起初清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)效(xiao)果顯著，使(shi)用(yong)一段時間后(hou)由于(yu)(yu)(yu)顆粒(li)(li)物(wu)堆積，使(shi)聲(sheng)(sheng)波(bo)(bo)輻(fu)射大(da)大(da)衰減，影響了零(ling)(ling)件(jian)(jian)(jian)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)的穩(wen)定性(xing)。針對此問題潤源為(wei)(wei)設(she)備(bei)附設(she)了自(zi)(zi)清(qing)(qing)(qing)(qing)(qing)潔(jie)系統(tong)，通過(guo)(guo)過(guo)(guo)濾循環、粉(fen)末分離裝(zhuang)置(zhi)保(bao)持介質(zhi)(zhi)(zhi)(zhi)純凈，從而(er)減輕(qing)超聲(sheng)(sheng)波(bo)(bo)工作壓(ya)力(li)，確保(bao)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)的穩(wen)定性(xing)。
