Xa abantu abaninzi besiva 'iimveliso ezenziwe ngomgubo wesinyithi', ngoko nangoko bacinga ngezo giya zincinci, zintsonkothileyo ezifakwe ngaphakathi okanye iibheringi zokuzithambisa. Akulunganga oko, kodwa kufana nje nokuchaza imoto ngeeplagi zayo zentlantsi. Ubunyani buzinze ngakumbi kubomi bemihla ngemihla boshishino kunoko. Kukho uluvo olungalunganga oluqhelekileyo, ngakumbi kwabo basebenza ikakhulu ngesinyithi esinyibilikisiweyo, njengakwisiseko sethu, ukuba iinxalenye ze-PM ziyindlela engabizi kakhulu, esebenza kancinci. Emva kokuchitha amashumi eminyaka eQingdao Qiangsenyuan Technology Co., Ltd. (QSY) malunga nokungunda kweqokobhe kunye nokuphosa utyalo-mali, bendidla ngokwabelana kancinci kolomkhethe. Kuphela kungokusebenzisana ngokuthe ngqo nababoneleli be-PM kunye nokuzama ukufaka izinto endaweni ethile endathi ndayiqonda ngokwenene apho isinyithi somgubo sikhanya khona-kwaye apho singenako kwaphela.
Ubume beShishini: Apho i-PM ingena khona
E-QSY, ihlabathi lethu liyintsimbi engamanzi-ukugalela, ukuqinisa, umatshini. Ke, xa umxhasi wendibano yevalve yehydraulic enyanzelisa ukusebenzisa i-PM-made valve spool endaweni yenguqulelo yethu eyenziwe ngomatshini we-CNC ukusuka kwisitokhwe sebha, ndandithandabuza. Umzobo wawufuna ulwakhiwo oluntsonkothileyo lwangaphakathi lomjelo owawuliphupha elibi kumatshini. Umnikezeli we-PM uhambise inxalenye ekufutshane nenetha. Ukuxinana kunye nokugqiba komphezulu yayizinkxalabo zangoko. Isebenzile, kodwa umlinganiselo woxinzelelo kuye kwafuneka uthotywe kancinane xa kuthelekiswa nokulingana okwenziweyo. Olo rhwebo-ubunzima bomnyinyiva omncinci kwiipropathi zokugqibela zoomatshini-yizibalo zemihla ngemihla kule ntsimi.
Kulapho esona sigqibo senzeka khona. Ayikokuba yeyiphi inkqubo 'engcono' kwivacuum. Kwiblayidi yeinjini yoxinzelelo oluphezulu kwialloyi esekwe nickel, utyalo mali yinqaba yethu. Kodwa kwi-volume ephezulu, ikhamera emile okwe-ferrous alloy, apho ukusetyenziswa kwezinto ezivela kumatshini kuya kuba ngaphantsi kwe-40%, i-metallurgy yomgubo iqala ukucula ingoma yayo ye-siren. Ingxoxo yenkcitho yezoqoqosho kunye neyezinto eziphathekayo iyoyikeka, ngaphandle kokuba uyilo luphuculwe ukucutha kunye ne-sintering kwasekuqaleni.
Ndikhumbula umzamo ongaphumelelanga wokusebenzisa intonga yokudibanisa i-PM kwinjini yomfuziselo. Idatha yokukhathala ibonakala ilungile ephepheni, kodwa silahlekelwe yi-nuance yeempawu ze-anisotropic. Inxalenye ayiphumelelanga ecaleni kwenqwelomoya ecinezelayo phantsi kokulayisha umjikelo, imowudi yokusilela ye-PM yakudala ukuba inxalenye ekhutshiweyo okanye ephosiweyo engayi kuyibonisa ngendlela efanayo. Yayisisifundo esinzima ukuba awukwazi nje ukuthatha umzobo kwinxalenye eyenziweyo kwaye uyithumele kwivenkile ye-PM. Uyilo kufuneka luthethe ulwimi lwenkqubo.
IiNgxoxo zezinto eziphathekayo: I-alloys kunye ne-PM Advantage
Oku kukhokelela kwizinto eziphathekayo. Umsebenzi wethu ku QSY kunye ne-alloys ezikhethekileyo ezifana ne-cobalt-based kunye ne-nickel-based based ons idla ngokugqithisileyo-ukushisa okuphezulu, ukubola. I-metallurgy yomgubo inomdlalo owahlukileyo apha apho ukubunjwa akunako ukuhambelana ngokulula: imidibaniso matrix metal kwaye izakhiwo zomgangatho. Ndibone iinxalenye ze-PM apho amasuntswana e-ceramic asasazwe ngokufanayo kwi-aluminiyam matrix yokumelana nokunxiba, into ephantse ingenzeki ukufikelela ngaphandle kolwahlulo oluqatha ekujuleni.
Kwizixhobo zensimbi ezinesantya esiphezulu, i-PM iyinkosi. Ubume obucolekileyo, obufanayo be-carbide osifumana kwi-atomizing kunye nokudibanisa umgubo uphumela kwisixhobo esicola ngcono kwaye sinxibe ngokulungeleleneyo ngakumbi kunomlinganiso waso wesiqhelo. Sifumana i-PM-ezenziwe izixhobo ezingenanto kumaziko ethu omatshini e-CNC. Umahluko wokuhambelana phakathi kweebhetshi uqina ngokubonakalayo.
Ukanti, kukho umda. Kwizinto ezinkulu, ezibaluleke kakhulu kwintsimbi engenastainless kusetyenziso lwaselwandle, sisajonge ekujuleni. Ukunyaniseka kwenxalenye ephoswe kakuhle, ubume bayo be-isotropic, kunye nokukwazi ukuvelisa amacandelo anzima kakhulu kusayinika umda. Amalungu e-PM, ngaphaya kobukhulu obuthile, alwela ukufana koxinaniso. Kusisithintelo somzimba wenkqubo yokucinezela.
Umdaniso weDimensional: Ukunyamezela kunye nokuSebenza okuSekondi
Inqaku elikhulu lokuxabana, okanye ukungaqondi kakuhle, kukunyamezelana okulinganayo. Isithembiso 'se-near-net-shape' ye umgubo wesinyithi yinyani, kodwa 'kufuphi' ligama elisebenzayo. Kwiimpawu ezihambelana necala elicinezelayo, unokubamba ukunyamezela okuchukumisayo, ngamanye amaxesha ngaphakathi kwesibini samawaka e-intshi. Kodwa kwicala elicinezelayo, ujongene ne-springback ye-compact kunye ne-sintering shrinkage, eyongeza ukuguquguquka.
Phantse yonke inxalenye ye-PM esikhe sajongana nayo iqhuba utyando lwesibini. Kulapho inkampani efana neyethu, enobunzulu CNC Machining ubuchule, buhlala bufika emfanekisweni. Isixhobo esine-sintered sinokufuna ukukrolwa okanye ukusila kumbhobho waso, okanye icandelo lolwakhiwo lunokufuna ubuso obubalulekileyo obotshwe ngoomatshini bokuqinisekisa ukutyibilika kwetywina. I-synergy icacile: I-PM idala ijometri entsonkothileyo ngokufanelekileyo, kwaye ukuchaneka kwe-machining yongeza ukubamba okubalulekileyo kokugqibela. Kukuxhawulana ngesandla phakathi kweenkqubo, hayi ukutshintshwa.
Ndikhumbula ndihlola ibhetshi ye-PM flanges apho umngxuma webholithi isangqa sasiyi-elliptical post-sintering. Unobangela? Uxinaniso olungenayunifomu olusuka kwiziko elingekhoyo gcwalisa idayizi. Umthengisi we-PM kwafuneka afake inyathelo lemali yokuyilungisa. Olu hlobo lwenkqubo ye-nuance alubonakali kwiphepha ledatha kodwa yinyani yemihla ngemihla yokuvelisa.
Ukuxabisa okungabonakaliyo: UQoqosho lokwenyani
Wonke umntu uthetha ngogcino lwempahla ye-PM, eyinyani-awujiki i-60% yemathiriyeli yakho ibe yi-chips. Kodwa ibali lexabiso lokwenyani likwisixhobo kunye nomthamo. Imibumbe yokubumba umgubo ibiza imali eninzi, intsonkothile, kwaye yomelele. Ziyavakala ngokuqhutywa kwemveliso yamaqhekeza angama-50,000, hayi ama-500. Oku kuchasene ngokupheleleyo nengqiqo yethu yesanti yokuphosa, apho ipateni yeplanga inexabiso eliphantsi kwaye iyakhawuleza.
Kukwakho neendleko ezifihliweyo zomgubo ngokwawo. Umgangatho ophezulu, umgubo wentsimbi osele ufakwe ngaphambili awubizi. Kumxube oqhelekileyo we-iron-copper-carbon, iyakhuphisana. Kodwa nje ukuba ungene kwezo zinto zisekwe kwi-nickel okanye umgubo wentsimbi, ixabiso lemathiriyeli ekrwada ngekhilogram nganye lingakunika unqumamo. Uhlawulela inkqubo ye-atomization kunye nokusabalalisa ubungakanani bamasuntswana alawulwayo. Ulungelelwaniso kufuneka luvele kwintsebenzo kunye nokupheliswa kwamanyathelo okucubungula ezantsi.
Senze uhlalutyo lweendleko ezipheleleyo kwintsapho yeendawo ezincinci ze-lever. Kwiiyunithi ezingama-5,000, umatshini we-CNC ovela kwisitokhwe sebha yayingabizi kakhulu. Ngeeyunithi ezingama-50,000, i-PM ibisezantsi ngama-30%. Kwiiyunithi ezingama-500,000, umsantsa ukhule ukuya phantse kuma-50%. Kodwa oku kubambe kuphela ukuba uyilo lwenxalenye luye lwadityaniswa kumatshini omnye wokushicilela. Ukongeza into yomgangatho wesibini ngokusebenza okwahlukileyo kubulale umda. Inqanaba lokuqhekeka kwezoqoqosho yinto ekujoliswe kuyo eshukumayo, enovakalelo olunzulu kububunzima boyilo.
Ukujonga ngapha kwe-Asle: Casting vs PM Perspective
Ukusuka kwisihlalo sam kwinkampani yokuphosa kunye neyomatshini, ukunyuka kwe-PM kuye kwafundisa. Kusinyanzele ukuba sibe bukhali malunga nesindululo sethu sexabiso. Kwiindawo ezinemingxuma yangaphakathi-njenge-impeller ene-blade egqunyiweyo-ukuphosa utyalo-mali kusenokoyiswa. PM ayinakuyenza loo nto. Kwiindawo ezifuna ingxinano egqibeleleyo kunye nobomi bokudinwa, njenge crankshaft yenjini esebenza kakhulu, ukubumba kusalawula, nangona i-PM forging ingena.
Kodwa kulo mhlaba mkhulu uphakathi wesakhiwo, ukunxiba, kunye nezinto zemagneti-cinga izihluzi sintered, ii-clutch hubs, iziqwenga zepali zeenjini-isinyithi somgubo sisoloko sisona sikhetho esingenakuphikiswa. Yinkqubo eqolileyo, entsonkothileyo. Ukuvela kobuchule obufana nokubumba inaliti yentsimbi (MIM) kuye kwawenza mfiliba ngakumbi imigca, ivumela iindawo ezincinci, ezintsonkothileyo ngendlela engazange ibekho i-PM okanye i-micro-casting inokusingatha ngokwezoqoqosho.
Ekugqibeleni, imalunga nokuba nesixhobo esifanelekileyo somsebenzi. Nge Qingdao Qiangsenyuan Technology Co., Ltd., amandla ethu akukuguqula isinyithi esilulwelo sibe ngamacandelo achanekileyo, athembekileyo. I-Metallurgy yomgubo yindalo enxuseneyo apho amasuntswana esinyithi esomeleleyo adityaniswa abe ngamacandelo abalulekileyo ngokulinganayo. Ezona njineli zikrelekrele ndizaziyo azithembisi ukuthembeka kwinkqubo enye. Baluqonda ulwimi lwabo bonke—ukwenza izinto, ukwenza oomatshini, ukukhahlela, kunye umgubo wesinyithi-kwaye ukhethe isiyelelane esibalisa kakhulu ibali lemveliso yabo. Umsebenzi wokwenyani uyenzeka kuguqulelo.
