Uyilo lweSixhobo sePowder Metallurgy

I-metallurgy yomgubo iguqula isinyithi okanye umgubo ongeyiyo intsimbi ibe ngamalungu anemilo ethile, iipropathi kunye nobukhulu ngokwamanyathelo afana nokuxuba umgubo, ukucofa kunye nokuntywila. Kule nkqubo, ukubunjwa akukona nje isixhobo sokubumba, kodwa kunye neyona nto ibalulekileyo ekunqumeni umgangatho wemveliso, ukulawulwa kweendleko kunye nokusebenza kakuhle kwemveliso. Ngoko ke, ukubaluleka koyilo lokungunda kuyabonakala.

Uyilo lokungunda kwesinyithi somgubo kufuneka luthathele ingqalelo ngokupheleleyo iipropathi zenyama kunye neekhemikhali zomgubo, indlela yokuziphatha koomatshini ngexesha lenkqubo yokubumba, kunye notshintsho olunobungakanani emva kokuntywila. Ngokomzekelo, i-fluidity ye-powder ichaphazela ngokuthe ngqo ukufana kokuzaliswa, ngelixa ukuhanjiswa koxinzelelo olucinezelayo kuhambelana ngokusondeleyo noyilo lwesakhiwo sokubumba. Ukongezelela, ukukhethwa kwezinto zokubumba kwakhona kufuneka kuthathelwe ingqalelo ukuxhatshazwa kokugqoka, ukuzinza kwe-thermal kunye nokuhambelana nomgubo ukuqinisekisa ukuba i-mold igcina ukuchaneka okuphezulu kunye nobomi obude ngexesha lokusetyenziswa.

Ngokwengxelo yophando ye-International Powder Metallurgy Association (IPMA), ukulungiswa koyilo lokungunda kunokuphucula kakhulu izinga lesivuno.iimveliso zomgubo wesinyithi, ukunciphisa izinga le-scrap, kwaye ngoko ukunciphisa iindleko zokuvelisa. Ngelo xesha, iinkampani ezininzi ezaziwayo ziye zaphumelela ngempumelelo ukuphuculwa kabini ekusebenzeni kwemveliso kunye nokusebenza kakuhle kwemveliso ngokuqhubeka nokuphucula i-mold design.

Imigaqo yoyilo lokungunda

Ukukhetha izinto eziphathekayo

Kuyilo lwe-powder metallurgy molds, ukhetho lwempahla ngumsebenzi ophambili. Izinto ezifanelekileyo zokubumba kufuneka zibe nobunzima obuphezulu bokumelana nokunxiba, ubunzima obuphezulu bokumelana nemithwalo yempembelelo ngexesha loxinzelelo, kunye nokuzinza okuhle kwe-thermal kunye nokumelana nokugqwala ukuziqhelanisa neendawo zobushushu obuphezulu.

Izinto zokubumba eziqhelekileyo ziquka i-carbide ene-cemented, i-hot work die steel, kunye neekeramics. I-carbide ene-cemented isetyenziswa ngokubanzi kwiimbumba ezinomthwalo ophezulu ngenxa yobunzima bayo obuphezulu kunye nokumelana nokunxiba kakuhle; umsebenzi oshushu die steel yenza kakuhle xa iphantsi kobushushu obuphezulu kunye noxinzelelo olutshintshanayo ngenxa yokuzinza kwayo okuhle kakhulu kwe-thermal kunye nokuqina; kunye nemathiriyeli ye-ceramic lukhetho olufanelekileyo kwiimeko ezithile ngenxa yobunzima babo obuphezulu kakhulu kunye nokuxhathisa umhlwa.

Inkqubo yokunyanga ukushisa kwezinto zokubumba inempembelelo ebalulekileyo ekusebenzeni kwabo. Ngokomzekelo, ukucima kunye nokufudumala kunokuphucula ukuqina kunye nokuqina kwentsimbi yokubumba; i-carburizing inokunyusa ukuqina kunye nokumelana nokunxiba kwendawo yokubumba. Ukongeza, itekhnoloji yonyango lomphezulu njenge-chrome plating kunye nokutshiza nge-ceramic inokwandisa ngokufanelekileyo ubomi benkonzo yokubumba.

Ngokutsho kophando olufanelekileyo lwe-ASM International (eyayisakuba yi-American Society for Metals), ukhetho olufanelekileyo lwezinto eziphathekayo kunye nenkqubo yokunyanga ukushisa kunokuphucula kakhulu ukuxhatshazwa kokugqoka kunye nobomi benkonzo yokubumba, ngaloo ndlela ukunciphisa iindleko zokuvelisa.

Ulwalathiso olutsha kuYilo lwePowder Metallurgy Mold

Digital Revolution

Ngophuhliso olukhawulezayo lwetekhnoloji yeCAD/CAE/CAM, uyilo lwedijithali lube yeyona ndlela iphambili yoyilo lokubumba isinyithi. Uyilo lwedijithali aluphuculi nje ukusebenza kakuhle koyilo kunye nomgangatho, kodwa lubeka isiseko sokuzaliseka kwemveliso ekrelekrele.

Umda weTekhnoloji:

Kwinkalo yoyilo lwedijithali,umgubo weMetallurgy 3D ubuchwepheshe bokushicilelayenza ukuba abaqulunqi be-mold bakwazi ukwakha kunye nokuguqula i-3D mold, ukuphucula kakhulu ukuchaneka kunye nokusebenza kakuhle koyilo. Kwangaxeshanye, ukusetyenziswa kwetekhnoloji ye-finite element analysis (FEA) yenza ukuba abaqulunqi baqikelele ukusasazwa koxinzelelo, ukuguqulwa kobumba ngexesha lenkqubo yokubumba, kunye neziphene ezinokubakho zemveliso kwinqanaba lokuyila, ukwenzela ukuba kulungiswe iskimu soyilo kwangaphambili kunye nokunciphisa inani kunye neendleko zovavanyo lokubumba.

Ukongeza, ngokunyuka kwe-computing yefu kunye nethekhnoloji yedatha enkulu, uyilo lokubumba luye lwaqalisa ukufudukela efini. Iqonga loyilo lwamafu libonelela ngamandla anamandla ekhompyuter kunye nokugcinwa kwedatha, okuvumela abaqulunqi ukuba bafikelele kwizixhobo zoyilo nanini na naphi na, basebenzisane namalungu eqela ngexesha langempela, kwaye bafezekise i-docking engenamthungo kunye nokuphindaphinda ngokukhawuleza koyilo.

Amandla okulinganisa:

Itekhnoloji yokulinganisa izise utshintsho oluguquguqukayo kuyilo lokungunda lwesinyithi. Ngokufanisa utshintsho lomzimba kunye neekhemikhali ngexesha lenkqubo yokubumba, abaqulunqi banokuqikelela ngokuchanekileyo ukumila, ubungakanani, ukusebenza kwemveliso kunye noxinzelelo lwe-mold, ngaloo ndlela baphucula isakhiwo sokubumba kunye neeparitha zenkqubo yokubumba. Oku buchule bokuxela kwangaphambili akuphuculi kuphela izinga lempumelelo yoyilo lwemveliso, kodwa kwakhona kunciphisa kakhulu umjikelo wophuhliso lwemveliso kunye nokunciphisa iindleko zophuhliso.

Umzekelo, ngokusebenzisa ukulinganisa uxinzelelo lwe-thermal, abaqulunqi banokuqonda impembelelo yokutshintsha kweqondo lokushisa kwi-mold ngexesha le-sintering kwiipropati eziphathekayo, kwaye emva koko ulungise uyilo lwenkqubo yokupholisa ye-mold ukunciphisa ukuguqulwa kunye nokuqhekeka okubangelwa uxinzelelo lwe-thermal ye-mold. Ngomnye umzekelo, ngokulinganisa ukuhamba kwepowder, abaqulunqi banokuqikelela indlela yokuzaliswa kwepowder kwi-mold, ukwandisa umjelo wokuzalisa kunye noyilo lwe-vent ye-mold, kunye nokuphucula ukufana kokuzaliswa komgubo kunye nezinga lesivuno.
