I-metallurgy yomgubo (I-Metallurgy yomgubo, ekubhekiselwa kuyo njenge-PM) iteknoloji ye-metallurgical apho umgubo wesinyithi (okanye umxube we-metal powder kunye nomgubo ongeyiyo-metal) usetyenziswa njengento ekrwada ukwenza iimveliso zetsimbi okanye izinto ngokubumba, ukutshisa okanye ukutshisa.Inkqubo yokuvelisa i-powder metallurgy ifana nenkqubo yokuvelisa iimveliso ze-ceramic, ngoko ke abantu bahlala bebiza indlela ye-powder metallurgy "indlela ye-cermet".
Ngophuhliso olukhawulezayo lwazo zonke iinkalo zobomi, iimfuno ezahlukeneyo ezifana noyilo olukhaphukhaphu kunye noyilo olubambeneyo, iindawo ezininzi ziya zisiba nzima ngakumbi nangakumbi, nto leyo ebangela inkqubo yokubumba umgubo wesinyithi ukujongana nemingeni engaphezulu.
Ngokunyuka kwesixa se-PM, iimfuno zenkqubo zibopheleleke ukuba zibe ngqongqo.Njengesona sixhobo sibaluleke kakhulu kumgca wemveliso wecandelo lesinyithi, umgubo wokwenza ushicilelo lwehydraulic umisela umgangatho wepowder compact kwaye unqanda uphuhliso lweshishini lomgubo wesinyithi eTshayina..I-high-performance powder press yi-powder eyenza imveliso ye-hydraulic press based on electro-hydraulic ratio technology, kodwa iteknoloji yayo ikwimeko evaliweyo.
Okwangoku, izityalo ezinkulu zokuvelisa umgubo wesinyithi ziye zazisa izixhobo zokwenza umgubo ophambili kunye nemigca yemveliso evela phesheya, kodwa intshayelelo yodwa ayinakuyisombulula ingxaki ngokusisiseko.Ke ngoko, uphuhliso oluzimeleyo lwezixhobo zokwenza umgubo wetekhnoloji ephezulu lukwayeyona ndlela inkulu yophuhliso kwishishini lomgubo.
Inkqubo yokwenza i-powder metallurgy
Ukubumba linyathelo elibalulekileyo kwinkqubo yesinyithi somgubo.Injongo yokwenza kukuvelisa i-compact enemilo ethile, ubukhulu, ubuninzi kunye namandla.Ukubumba ukunyanzeliswa yeyona ndlela isisiseko yokubumba.
Indlela yokubumba i-compression inenkqubo elula, ukusebenza kakuhle okuphezulu, kwaye ilungele imveliso ezenzekelayo.Nangona kunjalo, ukusabalalisa uxinzelelo lwale ndlela alufani, ukwenzela ukuba ubuninzi bomzimba obuhlaza bungafani, kwaye ukuqhekeka kulungele ukwenzeka, okukhokelela ekubonakaleni kwemveliso ephosakeleyo.
a.Ukufana kokusabalalisa koxinzelelo lwe-compact: Ngenxa yokuba umzimba we-powder ugeleza kuwo onke amacala emva kokugxininiswa kwi-die, kubangela uxinzelelo lwecala oluxhomekeke eludongeni lokufa.Uxinzelelo lwecala lubangela ukungqubuzana, okuya kubangela ukuhla koxinzelelo olubalulekileyo kwindlela yokuphakama kwe-compact.
Amanyathelo okuphucula: 1) Ukunciphisa ukungqubuzana, sebenzisa ioli yokuthambisa eludongeni lwangaphakathi okanye usebenzise isikhunta esinodonga lwangaphakathi olulula;
I-2) Ukunyanzeliswa kweendlela ezimbini kusetyenziselwa ukuphucula ukungalingani kokusabalalisa koxinzelelo lwee-compact eziluhlaza;
3) Zama ukunciphisa umyinge wobude bobude xa uyila isikhunta.
b.Ukunciphisa ingqibelelo: ngenxa yokwandiswa kwe-elastic ye-mold mold ngexesha lenkqubo yokucinezela, xa uxinzelelo lususiwe, i-compact ithintela ukunyanzeliswa kwe-elastic ye-mold mold, kwaye i-compact iphantsi koxinzelelo lwe-radial, ibangela ukuba i-compact ifumane ukucheba okubuyela umva. uxinzelelo ngexesha lenkqubo yokudiliza Ezinye iindawo ezibuthathaka kwi-compact zingatshatyalaliswa phantsi koxinzelelo lokucheba olukhankanywe ngasentla.
Amanyathelo okuphucula: Ngokubhekiselele kwisakhiwo, iinxalenye kufuneka ziphephe i-grooves enqabileyo, i-grooves enzulu kunye nemxinwa, imiphetho ebukhali, abaphathi abancinci nabancinci kunye nezinye iimilo kangangoko kunokwenzeka.
Ukusuka kula manqaku mabini angasentla, inkcazo erhabaxa yempembelelo yento enye kwinkqubo yokulawula ukubumba kumgangatho wemveliso, kodwa kwizicelo ezisebenzayo, izinto ezahlukeneyo ezinempembelelo ziyahambelana.Ngexesha lenkqubo yophando, kufumaniseka ukuba izinto ezichaphazela umgangatho wemveliso ngaxeshanye zezi:
1. Impembelelo yokwenza uxinzelelo kumgangatho we-billet: amandla acinezelayo anefuthe elithe ngqo kuxinaniso.Ukuhla koxinzelelo olukhoyo kubangela i-delamination kunye nokuxobula ngexesha lokucinezela, kwaye iintanda zikhona kwi-interface ye-compact emva kokudilizwa.
2. Umphumo wokunyanzeliswa kwesantya kumgangatho we-compact: Ngexesha lokudibanisa i-powder, isantya esichukumisayo sichaphazela ukukhutshwa komoya kwiipores phakathi kweepowders, kwaye kuchaphazela ngokuthe ngqo ukufana kwe-compact density.Umahluko woxinaniso we-compact mkhulu kakhulu.Okona kulula ukuvelisa iintanda.
3. Impembelelo yokubamba ixesha kumgangatho we-compact: Ngexesha lenkqubo yokucinezela, kufuneka kubekho ixesha elifanelekileyo lokubamba phantsi koxinzelelo oluphezulu, olunokunyusa kakhulu ubuninzi be-compact.
Isixhobo sokubumba sesinyithi somgubo esizenzekelayo esizenzekelayo esandula ukuphuhliswa yi-Chengdu Zhengxi Hydraulic Equipment Manufacturing Co., Ltd. siyilwe njengesixhobo esitsha sobuvulindlela sasekhaya esidibanisa izibonelelo zoomatshini bokushicilela kunye ne-CNC servo hydraulic presses.
Uhlobo lwetemplate edadayo isiseko sokubumba esidibeneyo sesixhobo sinokulawula ngokufanelekileyo ukuhambelana kwemveliso kunye nomgangatho ofanelekileyo wemveliso.Ngesiseko sokwanelisa ukunyanzeliswa koxinzelelo oluqhubekayo, inkqubo esisigxina yokucinezela umatshini wokushicilela umatshini wongezwa, ongenakusebenza kuphela njengomda kodwa njengendlela echanekileyo yokucinezela.Ukukhuselwa kwe-double-layer yokucinezela kunye nokucinezela kuphucula kakhulu ukuchaneka kwemveliso kunye nokusebenza kakuhle kwemveliso.
