Okuvame ukusetshenziswai-carbides enosimendeihlukaniswe yaba izigaba ezintathu ngokusho kokwakheka nezici zokusebenza kwazo: i-tungsten-cobalt, i-tungsten-titanium-cobalt, ne-tungsten-titanium-tantalum (i-niobium). Okusetshenziswa kakhulu ekukhiqizeni ama-tungsten-cobalt nama-tungsten-titanium-cobalt asimende ama-carbides.
(1) I-tungsten-cobalt cemented carbide
Izingxenye eziyinhloko yi-tungsten carbide (WC) ne-cobalt. Igama lomkhiqizo limelelwa ikhodi engu-YG (efakwe kuqala i-pinyin yesiShayina ethi “hard” kanye “ne-cobalt”), elandelwa inani lephesenti lokuqukethwe kwe-cobalt. Isibonelo, i-YG6 imele i-tungsten-cobalt cemented carbide enokuqukethwe kwe-cobalt okungu-6% kanye ne-tungsten carbide engu-94%.
(2) I-tungsten titanium cobalt carbide
Izingxenye eziyinhloko yi-tungsten carbide (WC), i-titanium carbide (TiC) ne-cobalt. Igama lomkhiqizo limelelwa ikhodi engu-YT (isiqalo se-pinyin yesiShayina esithi “hard” kanye “ne-titanium”), elandelwa inani lephesenti lokuqukethwe kwe-titanium carbide. Isibonelo, i-YT15 imele i-tungsten-titanium-cobalt carbide enokuqukethwe kwe-titanium carbide okungu-15%.
(3) I-tungsten titanium tantalum (niobium) uhlobo lwe-carbide enosimende
Lolu hlobo lwe-carbide enosimende lubizwa nangokuthi i-general cemented carbide noma i-universal cemented carbide. Izingxenye zayo eziyinhloko yi-tungsten carbide (WC), i-titanium carbide (TiC), i-tantalum carbide (TaC) noma i-niobium carbide (NbC) ne-cobalt. Igama lomkhiqizo limelelwa ikhodi ethi YW (efakwe kuqala i-pinyin yesiShayina ethi “hard” kanye “no-wan”) elandelwa yinombolo ye-ordinal.
Izicelo ze-carbide enosimende
(1) Izinto zamathuluzi
I-Carbide iyithuluzi elisetshenziswa kakhulu futhi lingasetshenziswa ukwenza amathuluzi okuguqula, ama-milling cutters, ama-planers, ama-drill bits, njll. Phakathi kwazo, i-tungsten-cobalt carbide ifaneleka ukucubungula i-chip emfushane yezinsimbi ezinsimbi nezinsimbi ezingenayo insimbi kanye nokucutshungulwa kwezinto ezingezona ezensimbi, njengensimbi ekhonjiwe, ithusi eliphonsiwe, i-bakelite, njll. I-tungsten-titanium-cobalt carbide ilungele ukucutshungulwa kwe-chip ende yezinsimbi ezisansimbi njengensimbi. Ukucutshungulwa kwe-chip. Phakathi kwama-alloys afanayo, lawo anokuqukethwe kwe-cobalt ngaphezulu afanele umshini onzima, kuyilapho lawo anokuqukethwe okuncane kwe-cobalt afanele ukuqedwa. Ukuphila kokucutshungulwa kwe-carbide yenhloso ejwayelekile yezinto ezisebenza kanzima emshinini njengensimbi engagqwali yinde kakhulu kuneyenye i-carbide.I-Carbide blade
(2) Isikhunta
I-Carbide isetshenziswa kakhulu njengoba kufa umdwebo obandayo, ukufa kokushaywa okubandayo, ukufa kwe-extrusion okubandayo, ukufa kwe-cold pier kanye neminye imisebenzi ebandayo iyafa.
Ngaphansi kwezimo zokusebenza ezingagugi zokufaka umthelela noma umthelela onamandla, ukufana kweamakhaza e-carbide enosimendeIsihloko siyafa ukuthi i-carbide enosimende iyadingeka ukuze ibe nokuqina okuhle komthelela, ukuqina kokuphuka, amandla okukhathala, amandla okugoba nokumelana nokugqokwa okuhle. Imvamisa, amamaki e-cobalt aphakathi nendawo aphezulu kanye naphakathi naphakathi nendawo namahhadlahhadla akhethwa, njenge-YG15C.
Ngokuvamile, ubudlelwano phakathi kokumelana nokugqoka kanye nokuqina kwe-carbide enosimende kuyaphikisana: ukwanda kokumelana nokugqoka kuzoholela ekwehleni kokuqina, futhi ukwanda kokuqina kuzoholela nakanjani ekwehleni kokumelana nokugqoka. Ngakho-ke, lapho ukhetha amamaki ayinhlanganisela, kuyadingeka ukuhlangabezana nezidingo ezithile zokusetshenziswa ngokusekelwe ezintweni zokucubungula kanye nezimo zokusebenza zokucubungula.
Uma ibanga elikhethiwe lijwayele ukuqhekeka kanye nokulimala ngesikhathi sokusetshenziswa, kufanele ukhethe ibanga elinokuqina okuphezulu; uma izinga elikhethiwe lijwayele ukuguga kanye nokulimala ngesikhathi sokusetshenziswa, kufanele ukhethe ibanga elinobulukhuni obuphezulu kanye nokumelana nokugqoka okungcono. . Amabanga alandelayo: YG6C, YG8C, YG15C, YG18C, YG20C ukusuka kwesobunxele kuya kwesokudla, ubulukhuni buyehla, ukumelana nokugqoka kuncipha, futhi ukuqina kuyanda; ngendlela efanayo.
(3) Amathuluzi okulinganisa nezingxenye ezingagugi
I-Carbide isetshenziselwa izinto ezifakwayo ezikwazi ukumelana nokuguga kanye nezingxenye zamathuluzi okulinganisa, ama-grinder anemba amabhere, amapuleti omhlahlandlela angenacenterless nezinduku zomhlahlandlela, amatop lathe nezinye izingxenye ezingagugi.
