Ungawakhiqiza kanjani ama-CDC cutters

I-PDC Cutter yasungulwa okokuqala ngabakwaGeneral Electric (GE) ngo-1971. yethulwa ngokwentengiso ngo-1976 ngemuva kokuthi kutholakale ukuthi iyasebenza kakhulu kunokuchotshozwa kwezinkinobho ze-carbide. Amabhithi e-PDC manje athatha ngaphezu kuka-90% wesamba sevidiyo yokumba emhlabeni. Kodwa uyazi ukuthi ama-CDC cutters akhiqizwa kanjani? Ngingathanda ukwabelana nawe ngolunye ulwazi lapha.

Izinto zokwakha

khetha idayimane le-premium, uyichoboze futhi uyilolonge futhi, wenze usayizi wezinhlayiyana ufane, uhlanze impahla yedayimane. Nge-tungsten carbide substrate sisebenzisa impushana emsulwa yekhwalithi ephezulu kanye nebanga elifanele le-carbide elinokumelana nomthelela omkhulu.

HTHP sintering

1. opharetha ochwepheshe kanye nezinsiza ezithuthukisiwe zokukhiqiza abasiki be-PDC

2. hlola izinga lokushisa nengcindezi ngesikhathi sangempela futhi ulungise ngesikhathi. Izinga lokushisa ngu-1300 - 1500℃. Ingcindezi ingu-6 - 7 GPA.

3. Ukukhiqiza ucezu olulodwa lwe-PDC Cutters kuzodinga cishe imizuzu engama-30 isiyonke.

Ukuhlolwa kwezingcezu zokuqala

Ngaphambi kokukhiqiza ngobuningi, hlola ucezu lokuqala ukuze ubone ukuthi luyahlangabezana yini nezidingo zekhasimende zobukhulu nokusebenza.

Ukugaya

1. ukugaya ubukhulu: gaya ububanzi obungaphandle nobude. sebenzisa i-grinder cylindrical ukwenza ukugaya kwangaphandle ku-billet yomkhiqizo. Ngenxa yokuthi impahla ingase iguquguquke phakathi nomfutho ophakeme kakhulu kanye nokuhlanganiswa kwezinga lokushisa eliphezulu, umkhiqizo otholiwe ungase ungabi nesimo esiphelele futhi uhlangabezane nemfuneko yokubukeka komkhiqizo, futhi isilinda esiphelele kufanele sitholwe ngokugaya kwangaphandle.

2. ukugaya i-chamfer: i-chamfer kufanele ibe ngu-0.1-0.5mm nge-engeli engu-45; ii-chamfer ingagaywa ngamadigri ahlukene ngokuhambisana nemfuneko yekhasimende.

Ukuhlolwa kwemikhiqizo eqediwe

Ukuqinisekisa ukuthi bonke abasiki be-PDC bafanelekile futhi abaguquki, kufanele sihlole abasiki bokugcina be-PDC. Ukuhlolwa kwezinto ezifana nokubukeka, ubukhulu, nokusebenza komzimba kufanele kwenziwe, bese kuhlukaniswa futhi kupakishwe imikhiqizo ngemva kokuhlolwa ukuze ifaneleke. Lesi isinyathelo esibalulekile sokuqinisekisa ikhwalithi yomkhiqizo; ukulinganisa kobukhulu bedayimane le-polycrystalline kufanele kugcizelelwe ngesikhathi sokuhlolwa komkhiqizo.

Ukupakisha

Ukubonakala nobukhulu bomkhiqizo ophumayo kufanele kuhlangabezane nezinga lezimboni, ngaphezu kwalokho, ukubukeka komkhiqizo nobukhulu akufanele kushintshe phakathi nokuhamba ibanga elide. Okokuqala ungene ebhokisini lepulasitiki, bese kuba yibhokisi.Izicucu ezingu-50 kuwo wonke amabhokisi epulasitiki.

Kwa-ZZbetter, singanikela ngezinhlobonhlobo zabasiki abathile.
