Yintoni umgubo wentsimbi?

Ingqokelela yamasuntswana esinyithi angaphantsi kwemilimitha enye ibizwa ngokuba ngumgubo wesinyithi. Le yimathiriyeli ekrwada yokuqala esetyenziswa kumgubo wesinyithi kwaye ibandakanya intsimbi enye, ialloyi, kunye nomgubo othile odibeneyo owenziweyo oneempawu zetsimbi.

Yintoni amalungu entsimbi engumgubo?

Iinxalenye zetsimbi inkqubo yokwenza isinyithi okanye ukusebenzisa umgubo wesinyithi (okanye umgubo wesinyithi kunye nomxube we-non-metal powder) njengento ekrwada, emva kokwenza kunye ne-MIM sintering, izinto zokuvelisa isinyithi, izinto ezidibeneyo kunye neentlobo ezahlukeneyo zeteknoloji yeemveliso. Ishishini lamalungu omgubo wesinyithi ngokubanzi abandakanya izixhobo zentsimbi kunye nelitye, i-carbide enesamente, imathiriyeli kazibuthe. Ngengqiqo emxinwa, Ishishini lamalungu esinyithi somgubo libhekisa kuphela kwiimveliso zesinyithi somgubo, kubandakanyaiindawo zesinyithi somgubo(ukubalwa kobuninzi), ukuthwala ioli kunyeimveliso yokubumba inaliti yesinyithi.

Amacandelo ensimbi yomgubo

Iimpawu zePowder Metal Character

• ubuninzi bemveliso buyakwazi ukulawulwa, njengezinto eziphathekayo, izinto ezintle zobuninzi;
• ingqolowa ecolekileyo, i-microstructure efanayo, akukho ukwahlula kwamacandelo;
• kufutshane nokwakhiwa, izinga lokusetyenziswa kwemathiriyeli ekrwada > 95%;
• ngaphantsi akukho ukusika, ukusika processing kuphela 40 ~ 50%;
• ukubunjwa kwezinto eziphathekayo kulawulwa, okuhambelana nokulungiswa kwezinto ezidibeneyo;
• ukulungiswa kwentsimbi ephikisayo, imathiriyeli yeseramic kunye nezixhobo zenyukliya.

Iinxalenye zesinyithi zomgubo ezisisiseko sokuhamba

1, Ukuxubha

Ukucoca yinkqubo yokwenza imathiriyeli ekrwada ibe ngumgubo. Iindlela ezisetyenziswa ngokuqhelekileyo zokucolisisa yindlela yokunciphisa ioksidi kunye nendlela yomatshini.

2. Ukuxuba

Ukuxuba yinkqubo yokwenza i-billet powder ngokuxuba zonke iintlobo zepowder efunekayo kumlinganiselo othile kunye ne-homogenizing. Yahlulahlulwe yaba mithathu eyomileyo, enesiqingatha-yomileyo kwaye imanzi, ngokulandelelana kwiimfuno ezahlukeneyo.

3, Ukubumba

Ukuqulunqa yinkqubo yokwenza i-blank enemilo ethile, ubukhulu kunye nobuninzi ngokulayisha izinto ezixutywe ngokulinganayo kwi-pressing die phantsi koxinzelelo olunzima. Indlela yokubumba yahlulwe ngokusisiseko ibe kukubumba koxinzelelo kwaye akukho ukubunjwa koxinzelelo. Ukubunjwa koxinzelelo yeyona nto isetyenziswa kakhulu ekubumbeni.

4, Sintering

5. Emva kokulungiswa

 Emva konyango lwe-sintering, ngokweemfuno ezahlukeneyo zenxalenye yentsimbi yomgubo, thatha iindlela ezahlukeneyo. Okufana nokugqiba, ukudipha, umatshini, unyango lobushushu kunye ne-electroplating. Ukongeza, kule minyaka yakutsha nje, ezinye iinkqubo ezintsha ezinje ngokuqengqeleka kunye nokubunjwa ziye zasetyenziswa ekutshizeni umgubo wezixhobo zesinyithi kwaye zafumana iziphumo ezingcono.

Ukucoca umguboyinkqubo ephambili kwinkqubo yesinyithi somgubo. Emva kokwenza, i-billet ifakwe kwi-sintered ukuze ifumane iimpawu ezifunwayo zokugqibela zomzimba kunye nezomatshini. I-Sintering kwi-metallurgy yahlulwe ibe yiyunithi ye-sintering kunye ne-multi-system sintering. Ukongeza kwi-sintering eqhelekileyo, kukho i-sintering ekhululekileyo, ukuntywiliselwa, ukucinezela okushushu kunye nenye inkqubo ekhethekileyo yokucoca.
