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.

Iithegi zeMveliso

Olona ncedo luphambili lwesinyithi somgubo kukuba lwenziwe ngezinto zomgubo ezifakwe kwi-sintered, ngoko ke ibhafu yeoyile ilunge kakhulu, imilo yezinyo kunye nobungakanani bazo zonke iisayizi zinokubunjwa, ayilulo olunye uqwalaselo. igiya, amandla awonelanga, akakwazi ukuhambisa itorque enkulu, ukuchaneka kwamazinyo ngokuqhelekileyo kukwinqanaba le-6 ~ 9, ukuchaneka komda jikelele lelona nqanaba liphezulu le-IT7 ~ 6.

I-Metallurgy ye-Powder yiteknoloji entsha yokuvelisa, kunye neenzuzo zayo, ngokukodwa ezifanelekileyo kwimveliso yobuninzi.Kodwa akusiyo yonke imeko.I-powder metallurgical processing ifuna ukuveliswa kwefa ehambelanayo, usebenzisa isinyithi somgubo ngokusebenzisa i-sintering kunye nenkqubo ehambelanayo yokwenza i-parts.Amandla ayahluka ngokwezinto ezisetyenzisiweyo.

1. Ubuninzi besinyithi esichasayo kunye neekhompawundi zabo, i-alloys yobuxoki, izinto ezixubileyo zingenziwa kuphela nge-powder metallurgy method.

2. ngenxa yokuba indlela ye-metallurgy yomgubo inokucinezelwa kubungakanani bokugqibela bokuxinana, ngaphandle okanye imfuneko encinci yokucutshungulwa komatshini olandelayo, inokusindisa kakhulu isinyithi, inciphise iindleko zemveliso. Ukulahleka kwesinyithi ekwenzeni iimveliso ngomgubo wesinyithi. indlela yi-1-5% kuphela, ngelixa ilahleko yentsimbi ekuveliseni iimveliso ngendlela eqhelekileyo yokuphosa ingaba phezulu njenge-80%.

3. ngenxa yokuba inkqubo ye-metallurgy ye-powder kwinkqubo yokuvelisa izinto ayinyibiliki izinto eziphathekayo, ayikoyiki ukuxuba kunye nokungcola okuziswa yi-crucible kunye ne-deoxidizer, kwaye i-sintering iqhutyelwa ngokubanzi kwi-vacuum kunye nokunciphisa umoya, ungoyiki i-oxidation. , kwaye ayiyi kunika nayiphi na into engcolileyo kwizinto eziphathekayo, kunokwenzeka ukwenza izinto ezicocekileyo eziphezulu.

4. indlela ye-powder metallurgy inokuqinisekisa ukuchaneka kunye nokufana komlinganiselo wokubunjwa kwezinto.

5. i-metallurgy yomgubo ifanelekile kwimveliso yesimo esifanayo kunye nenani elikhulu leemveliso, ngokukodwa izixhobo kunye nezinye iindleko eziphezulu zokulungisa iimveliso, kunye nokuveliswa kwesinyithi somgubo kunokunciphisa kakhulu imveliso ye-cos.

1. Ubuninzi besinyithi esichasayo kunye neekhompawundi zabo, i-alloys yobuxoki, izinto ezixubileyo zingenziwa kuphela nge-powder metallurgy method.

4. indlela ye-powder metallurgy inokuqinisekisa ukuchaneka kunye nokufana komlinganiselo wokubunjwa kwezinto.

Ukulawulwa kobulukhuni beemveliso ze-metallurgy ngokubanzi ngexesha lonyango lobushushu:

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.
