I-Powder Metallurgy iSakhiwo seZahlulo ezibonisiweyo

I-Powder Metallurgy Izahlulo zeZakhiwo

Inkcazelo emfutshane:

Oku kubhekiselele kwintsimi ekhethekileyo yesinyithi somgubo, njengoko ubuninzi, i-porosity, izixhobo kunye neendlela zokunyanga ubushushu bezixhobo zesinyithi somgubo zichaphazela ngqo ukuqina kunye namandla. izinto eziphathekayo, ukuqina okuphezulu.Iindlela zonyango zokushisa ngokubanzi ziquka ukucima i-carburizing, i-carbonitriding, ukucima i-frequency quenching, i-low frequency quenching, ukucima ioli, njl.Inkqubo yokucima i-oyile ezinzileyo kunye nefanelekileyo igcina ubulukhuni bonyango oluzinzileyo.

Amandla enkampani

Iithegi zeMveliso

Ubuninzi bepowder ye-atomized eqhelekileyo (kubandakanywa ne-carbon steel kunye ne-copper-carbon alloy steel steel) ingaphezulu kwe-6.9, kwaye ubunzima bokucima bunokulawulwa malunga ne-HRC30.

Ngokuqhelekileyo, ubuninzi be-powder pre-alloyed (AB powder) budlula i-6.95, kwaye ubunzima bokucima bunokulawulwa malunga ne-HRC35.

Iipowder eziphezulu ezifakwe ngaphambili kunye noxinano olukhulu kune-6.95 kunye nokucima ubunzima obulawulwa kwi-HRC40.

Iimveliso ze-metallurgy ze-powder ezenziwe kwezi zinto zingasentla zinezinzile kunye nezixhobo, kwaye ubunzima emva kokunyanga kobushushu buhlangabezana neemfuno ezihambelanayo, ngoko ke amandla abo okunyamezela kunye namandla okunyamezela aya kufikelela kwincopho engcono.

Ngaba unyango ubushushu ubulukhuni metallurgy umgubo ukufikelela 45 steel? Kakade unako!

Nangona kunjalo, ngenxa yokuba ubuninzi beemveliso ze-PM abukho ngaphezu kweNombolo ye-45 yensimbi, ubuninzi bezinto ezixinzelelekileyo ze-PM zivame ukuba yi-7.2 g / cm, ngelixa ubuninzi be-45 yensimbi yi-7.9 g / cm. yomgubo wesinyithi okanye unyango lobushushu obugqithisa kwi-HRC45 iya kwenza iimveliso zesinyithi somgubo zibe brittle ngenxa yokucima okuphezulu, okukhokelela ekomeleleni kwemveliso yomgubo wesinyithi.

Emva koko, siya kuthelekisa i-P / M yokwenza i-gear kunye ne-hobbing gear yomatshini.

1. Izinga eliphezulu lokusetyenziswa kwezinto, ukuya kuthi ga kwi-95%

2. Hayi okanye ukusika okuncinci kuphela kuyadingeka

3. Ukuhambelana kakuhle kwe-dimensional yamacandelo, ukuzinza okulungileyo kunye nokuchaneka okuphezulu.

4. Uthelekiso lwamandla: abavelisi besinyithi somgubo obuchwephesha balwenze ngcono uyilo lokubumba isinyithi somgubo, kwaye amandla okuqina kunye namandla acinezelayo egiya avelisiweyo asondele kuleyo yegiya yokuhombisa. Umzekelo, igiya eqhutywayo yebhokisi yemoto enokuhanjiswa okuphezulu. ukuqina ikwangumgubo wegiya yesinyithi.Ebonakalayo, igiya yomgubo wesinyithi iyasebenza kwaye ibanzi.

5. Ukubunjwa kwepowder usebenzisa ukubumba, kunokuvelisa enye iteknoloji yokusika i-hobbing ayikwazi ukuvelisa iimilo ezinzima.

6. Ngenxa yokuba ifanelekile kwimveliso yobuninzi, ukuveliswa kwemveliso kuphezulu kwaye ixabiso liphantsi kunokusika.

7. Ifanelekile kwimveliso yobuninzi, ngoko ke ixabiso likhuphisana ngokupheleleyo.
