Izinti ze-Carbide ezihlanganisiwe: Umgogodla Wezimboni Wokukhiqiza Kwesimanje
Izinti ze-carbide ezisasimende, ezivame ukubizwa ngokuthi "amazinyo emboni," ziwuhlobo oluyisisekelo futhi olusetshenziswa kabanzi lomkhiqizo we-carbide owenziwe usimende. Badlala indima ebalulekile emikhakheni eminingi ngenxa yezakhiwo zabo ezihlukile.
Isingeniso kanye Nokukhiqiza
Izinti ze-carbide ezinosimende ziyimigoqo eyisilinda eyenziwe ngokuyinhloko ngezinhlayiya ze-tungsten carbide eziqine kakhulu ezihlanganiswe ndawonye nge-matrix yensimbi ye-cobalt. Le nhlanganisela ifinyelelwa ngezinqubo ze-powder metallurgy, ezibandakanya ukucwiliswa emazingeni okushisa aphezulu nezingcindezi, okubanikeza izici ezingenakuqhathaniswa:
Ukuqina Okukhethekile Nokumelana Nokugqoka:Ubulukhuni bazo busondela kobedayimane, bubanike impilo ende yesevisi ngisho nasezindaweni ezilimaza kakhulu.
Amandla Okucindezela Okuvelele:Bangakwazi ukumelana nokucindezela okukhulu ngaphandle kokukhubazeka.
Ukuqina Okuhle Kakhulu:Bagcina ukuzinza ngesikhathi sokusebenza komshini, behlisa ukudlidliza.
Izigaba Eziyinhloko kanye namaBanga
Ukuhlukaniswa nokukhethwa kwezinti ze-carbide ezisasimende kubalulekile futhi ngokuyinhloko kusekelwe kokuqukethwe kwe-cobalt nosayizi wezinhlamvu ze-tungsten carbide.
Ukuhlelwa ngokuqukethwe kwe-Cobalt:
● Amabanga e-Low-Cobalt (isb., i-YG6): Lawa mabanga anokuqukethwe okuphansi kwe-cobalt (isb., 3% -6%). Zibonakala ngobulukhuni obuphezulu kanye nokumelana nokugqoka okuphezulu, nakuba zinokuqina okuphansi. Afaneleka kahle kumathuluzi wokuqeda amahle kanye nezingxenye ezidinga ukunemba okuphezulu ngaphandle kokugqoka ngokweqile.
● Amabanga Amaphakathi/Aphezulu-Cobalt (isb., YG8, YG15): Lawa aqukethe okuqukethwe okuphezulu kwe-cobalt (isb., 8% -15%). Ukwenyuka kokuqukethwe kwe-cobalt kuthuthukisa ukuqina kwento kanye nokumelana nomthelela, kodwa ngokuhambisanayo kunciphisa ubulukhuni nokumelana nokugqokwa. Zifanele izinhlelo zokusebenza ezinamandla amakhulu, njengezingcezu zezimayini nezinsimbi zokubhoboza.
Ukuhlukaniswa ngosayizi Wokusanhlamvu:
● I-Coarse Grain: Inikeza ukuqina okuhle kanye nokumelana nomthelela omuhle kakhulu, okuvame ukusetshenziswa kumathuluzi ezimayini kanye nezinsimbi zokubhoboza ezishaywayo.
● Okusanhlamvu Okumaphakathi: Ishaya ibhalansi phakathi kokuqina nokuqina, iyenze ibe yibanga elisetshenziswa kakhulu kumathuluzi omshini ajwayelekile.
● Okusanhlamvu Okuhle Futhi Okuhle Kakhulu: Lezi zimpawu zezinhlamvu ezinhle kakhulu, ezihlanganisa ubulukhuni obuphezulu namandla okuphuka aguquguqukayo aphezulu, okuholela ekusebenzeni okuphezulu kakhulu kukonke. Asetshenziselwa ukukhiqiza amathuluzi anembayo (njenge-PCB micro-drill), amathuluzi okusika izinto eziqinile, namathuluzi adinga imiphetho ebukhali yokusika.
Izindawo Zokusebenza Eziyinhloko
Ukusetshenziswa okuyinhloko kwezinduku ze-carbide ezisasimende kufana nezinto ezingavuthiwe (izikhala) eziqondile, ezisikiwe, noma ezilolongelwe nge-EDM zibe amathuluzi ahlukahlukene okusebenza okuphezulu nezingxenye.
● Amathuluzi Okusika: Lena indawo yabo ebaluleke kakhulu yohlelo lokusebenza. izintambo zisetshenziselwa ukwenza:
● Ama-Drill Bits: Njenge-PCB (Printed Circuit Board) ama-micro-drill, ama-twist drill, kanye ne-deep-hole drill.
● Imishini Yokugcina: Isetshenziswa ezikhungweni zemishini ye-CNC.
● I-Reamers: Ukuze uthole ukunemba okuphezulu kwezimbobo.
● Amathuluzi Okuguqula: Amanye amathiphu wamathuluzi okujika akhiwe ngomshini.
● Amathuluzi Ezimayini naweGeological: Ezimayini, ekumbiweni kukawoyela, nasekuhloleni indawo, izinduku ziyizinto ezibalulekile zokwenza izingcezu zokubhoboza amatshe nezipikili, ezikwazi ukugqobhoza amatshe aqinile.
● Izingxenye Ezikwazi Ukungezwani Nokugqoka: Ezimweni zokusebenza ezinzima, izinduku zisetshenziswa njengezindandatho zokuvala uphawu, imibhobho, izikhonkwane zokuqondisa, namarola, asebenzisa ukumelana kwazo okukhethekile nokwelula impilo yesevisi yemishini.
● Izinsimbi Nezikhunti Ezinembayo: Izinti zokusanhlamvu ezicoke kakhulu zingasetshenziswa ukwenza isikhunta esinembayo, ama-probe, nama-mandrel enhloso ekhethekile.
Indlela Yokukhetha Okulungilet I-Cemented Carbide Round Rod?
Ukukhetha kudinga ukuthola ibhalansi elungile phakathi "kokuqina/ukumelana nokugqoka" kanye "nokuqina" okusekelwe ezintweni ezithile ezicutshungulwayo nezimo zokusebenza:
● I-Material Iyacutshungulwa: Ukuze kwenziwe imishini ye-cast cast iron and non-ferrous metal, amamaki e-YG (K) afanelekile. Ngensimbi, amamaki e-YT (P) noma amamaki e-YW (M) jikelele ayakhethwa.
Izimo zokusebenza:
● Qedela Ukukhanda, Ukumelana Okuphezulu Kwe-Wear: Khetha i-cobalt ephansi, amamaki ezinhlamvu ezinhle.
● Imishini Enzima, Umthelela Ophakeme: Khetha amamaki aphakathi/aphezulu-cobalt, ama-coarse-grain.
● Izinto Zokusebenza Ezinzima Ziya Emshinini, Ukunemba Okuphezulu: Beka phambili amamaki okusanhlamvu amahle kakhulu.
Isifinyezo
Sengiphetha, izinduku ze-carbide ezisasimende, ezinezakhiwo ezivelele ezibonakalayo, ziyizinto eziyisisekelo ezibalulekile ezimbonini zanamuhla zokukhiqiza nezimayini. Ukuqonda ukuhlukaniswa kwazo, izici, kanye nezicelo kubalulekile ekukhetheni okulungile, ukukhulisa ukusebenza kwazo, kanye nokuthuthukisa ukusebenza kahle kokukhiqiza kuyilapho kunciphisa izindleko.
