I-metallurgy ye-powder luhlobo olutsha lwetekhnoloji yokubumba umnatha, esebenzisa ukunyibilika, ukufudumeza, inaliti kunye nokucinezela umgubo wentsimbi ukwenza ukubumba okufunekayo.Kwezinye izinto ezikhethekileyo ezifana neentsimbi eziphikisayo, iintsimbi eziphikisayo, i-alloy ephezulu kunye nokunye.Ke zeziphi izinto ezichaphazela umgangatho we-powder metallurgy ecinezela ukwenziwa kwamalungu emoto?

Ⅰ: Impembelelo yokucinezela ukwenza ukufa

Kuyabonakala ukuba ukufa kubalulekile kubuchwephesha bokubumba obucinezelayo.Kucetyiswa ukuba usebenzise i-female die okanye i-mandrel eyenziwe nge-samente ye-carbide, umgubo wentsimbi ephezulu kunye nezinye izinto.Xa i-fa (ezifana nomngxuma ongaphakathi womfazi kunye nobubanzi obungaphandle be-mandrel) isebenza, i-mandrel encinci incinci, kungcono ukunciphisa i-friction factor phakathi kwamasuntswana omgubo kunye nodonga lokufa.

Ukuba yinto enkulu okanye entsonkothileyo engenanto, ukucinezela ixesha elide kuya kubangela ukuba isikhunta sowesifazane sifudumale kwaye sigxumeke, isixhobo sokupholisa amanzi singasetyenziselwa ukunciphisa ubushushu bomngundo obhinqileyo kunye nokunciphisa i-friction factor.

Ukongeza, kuyilo lokungunda kwabasetyhini, kufuneka sigxininise kumandla kunye nokuqina, okunokunciphisa inqanaba lobushushu bomzimba womfazi, ukunciphisa ilahleko yoxinzelelo, kunye nokuthintela ukuqhekeka kwinkqubo yokucinezela iinxalenye zemoto.

Ⅱ: Impembelelo yokungunda kunye ne-lubricant

Kwinkqubo yokucofa i-metallurgy kunye nokwenza iinxalenye zemoto, ngenxa yelahleko yoxinzelelo olubangelwa kukungqubana phakathi komgubo oxutyiweyo kunye nodonga lokungunda, ukuxinana kokuhanjiswa kwee-compact akulingani.I-Mixin Powder icebisa ukuba kusetyenziswe ukubunjwa kokuqina okuphezulu okanye i-lubricant engcono.

Ⅲ: Impembelelo yezithambiso

Ukongeza i-lubricant kwi-metal exutywe ngumgubo kunokunciphisa ngokufanelekileyo ingxabano phakathi komgubo kunye nodonga lokubumba, kwaye wenze ukusabalalisa kobuninzi be-compact ngaphezulu ngokufanayo.Isithambiso esisetyenziswa ngokuqhelekileyo yizinc stearate.Nangona inokuphucula iimeko zokucinezela kunye nokwenza, kulula ukuvelisa ulwahlulo emva kokuxubana ngenxa yokuxinana okuncinci, kwaye iindawo ezixubileyo zixhomekeke kwi-pitting kunye nezinye iingxaki.

Ukusebenzisa i-lubricant efanelekileyo kunokuphucula ngokufanelekileyo ukungqubana phakathi komgubo kunye nodonga lokubumba, kunye nokunciphisa kakhulu impazamo yoxinaniso lwe-compact.Kwinkalo yokuxuba umgubo, ingqwalasela kufuneka ihlawulwe kwakhona kwindlela yokuxuba umgubo, enokunciphisa ukungqubana.

Ⅳ: Impembelelo yokucofa iiparamitha

1: Isantya soxinzelelo

Ukuba isantya soxinzelelo sikhawuleza kakhulu, siya kuchaphazela ukufana koxinaniso lwe-compact, kwaye luya kuvelisa ukuqhekeka.Kungcono ukusebenzisa umatshini wokwenza umgubo wehydraulic kwimveliso.

2: Ixesha lokubamba uxinzelelo

Ubuninzi be-compact obunjwe ngumgubo we-metallurgy ucinezela iindawo zemoto zinokunyuswa kakhulu phantsi koxinzelelo olukhulu loxinzelelo kunye nexesha elifanelekileyo lokubamba.

I-3: Ubume beebhuthi zokutyisa umgubo

Ukuba i-powder feeding shoe jikelele isetyenziselwa ukulayishwa kwepowder, iya kubangela ukugcwaliswa kwe powder engalinganiyo phezulu kunye nezantsi kwi-mold cavity okanye ngaphambili nangasemva, okuya kuchaphazela umgangatho ongenanto.Ukuphucula okanye ukuhlengahlengisa isicathulo sokutya umgubo kunokuphucula ingxaki yokulayisha umgubo.
