Ukuvelisa njani abasiki bePDC

I-PDC Cutter yasungulwa okokuqala nguMbane oMbane (GE) ngo-1971. yaziswa ngokurhweba ngo-1976 emva kokuba ibonakaliswe ukuba isebenze kakhulu kunezenzo ezityumzayo zamaqhosha e-carbide. Amasuntswana ePDC ngoku athatha ngaphezulu kwe-90% yetotali yokugrumba ividiyo ehlabathini. Kodwa ngaba uyazi ukuba ii-PDC cutters zenziwa njani? Ndingathanda ukwabelana nawe ngolwazi apha.

Izinto eziphathekayo

khetha idayimane yeprimiyamu, uyityumze kwaye uyilolonge kwakhona, ukwenza ubungakanani besuntswana bufanane ngakumbi, ukucoca impahla yedayimani. Kwi-tungsten carbide substrate sisebenzisa i-powder ye-virgin ephezulu kunye nebakala elifanelekileyo le-carbide elinokumelana nempembelelo ephezulu.

HTHP sintering

1. umqhubi weengcali kunye nezibonelelo eziphambili zokuvelisa i-PDC cutters

2. khangela ubushushu kunye noxinzelelo ngexesha langempela kwaye ulungelelanise ngexesha. Ubushushu buyi-1300 - 1500℃. Uxinzelelo yi-6 - 7 GPA.

3. Ukuvelisa isiqwenga esinye sePDC Cutters kuya kufuna malunga nemizuzu engama-30 iyonke.

Ukuhlolwa kweziqwenga zokuqala

Ngaphambi kokuveliswa kobuninzi, jonga iqhekeza lokuqala ukuze ubone ukuba liyahlangabezana neemfuno zomthengi zobungakanani kunye nokusebenza.

Ukusila

1. ukugaya umlinganiselo: gaya ububanzi obungaphandle kunye nokuphakama. sebenzisa i-cylindrical grinder ukwenza ukugaya kwangaphandle kwi-billet yemveliso. Ngenxa yokuba izinto eziphathekayo zinokuthi ziguquguquke ngexesha loxinzelelo oluphezulu kunye nobushushu obuphezulu, imveliso efunyenweyo ayinayo imilo egqibeleleyo kwaye ihlangabezane nemfuneko yokubonakala kwemveliso, kwaye i-cylinder epheleleyo kufuneka ifunyenwe ngokusila kwangaphandle.

2. i-chamfer yokugaya: i-chamfer kufuneka ibe malunga ne-0.1-0.5mm kunye ne-angle ye-45; ii-chamfer inokucolwa kwiidigri ezahlukeneyo ngokuhambelana nemfuno yomthengi.

Ukuhlolwa kweemveliso ezigqityiweyo

Ukuqinisekisa ukuba bonke abasiki bePDC bafanelekile kwaye bayahambelana, kufuneka sihlole abasiki bePDC bokugqibela. Ukuhlolwa kwezinto ezifana nenkangeleko, imilinganiselo, kunye nokusebenza komzimba kufuneka kuqhutywe, emva koko kuhlelwe kwaye kupakishwe iimveliso emva kokuba zihlolwe ukuba zifaneleke. Eli linyathelo elibalulekileyo lokuqinisekisa umgangatho wemveliso; ukulinganiswa kobunzima bedayimane ye-polycrystalline kufuneka kugxininiswe ngexesha lokuhlolwa kwemveliso.

Ukupakisha

Ukubonakala kunye nemilinganiselo yemveliso ephumayo kufuneka ihlangabezane nomgangatho wezoshishino, ngaphezu koko, ukubonakala kwemveliso kunye nemilinganiselo akufanele itshintshe ngexesha lokuthutha umgama omde. Okokuqala kwibhokisi yeplastiki, emva koko kwi-carton.50 iziqwenga kwibhokisi nganye yeplastiki.

Kwi-ZZbetter, sinokunika uluhlu olubanzi lwabasiki abathile.
