Yiziphi Izindlela Zokuqinisekisa Nokuthuthukisa Ukunemba Kwemishini?
I-1) Ubuchwepheshe bokuvimbela amaphutha: ukusetshenziswa okunengqondo kobuchwepheshe obuthuthukisiwe kanye nemishini yokunciphisa ngokuqondile iphutha lokuqala lokudlulisa iphutha iphutha lokuqala elingaphansi kwephutha lokuqala le-homogenization.
2) Ubuchwepheshe besinxephezelo sephutha: ukutholwa ku-inthanethi komshini wokugaywa ofanayo osebenzayo wokulawula okusebenzayo kwendima ewujuqu yezinto zamaphutha.
-Yini eyenzaimishinisurface geometry zihlanganisa?
Ubulukhuni beJiyomethri, ukubola kwendawo, indlela yokuthungwa, ukonakala kwendawo.
-Iziphi izici ezibonakalayo namakhemikhali ezinto zongqimba lwangaphezulu?
1) Umsebenzi obandayo uqina wensimbi yongqimba lwangaphezulu
2) Ukuguqulwa kwe-Metallographic yensimbi yongqimba olungaphezulu
3) Ukucindezeleka okusalayo kwensimbi yongqimba lwangaphezulu
-Zama ukuhlaziya izici ezithinta ubulukhuni bendawo yomshini?
1) Inani lobunzima liqukethe: ubude bendawo yokusika eyinsalela.
2) Izici eziyinhloko: i-tip arc radius, i-engeli enkulu yokuchezuka, ukuphambuka kwe-Engela feed
3) Izici zesibili: ukukhulisa isivinini sokusika, ukukhetha uketshezi lokusika ngendlela efanele futhi kwandise i-rake Angle yethuluzi ukuthuthukisa ikhwalithi yokugaya ithuluzi.
-Hlaziya izinto ezithinta ubulukhuni obungaphezulu benqubo yokugaya.
1) Izici zeJiyomethri: umthelela yenani lokugaya kumaholoholo angaphezulu
2) Umthelela wobumbudumbudu besondo lokugaya kanye nokugqoka kwesondo lokugaya phezu kobunzima obungaphezulu
3) Ithonya lezinto ezibonakalayo: ukuguqulwa kwepulasitiki kwensimbi yongqimba: ukukhethwa kwesondo lokulinganisa lokugaya
Zama ukuhlaziya izici ezithinta ukuqina komsebenzi obandayo kwendawo yokusika?
Umthelela wokusika amapharamitha umthelela wejiyomethri yethuluzi umthelela wezakhiwo ezibonakalayo
Kuyini ukuvutha kolaka? Kuyini ukugaya ukucisha ukushisa? Kuyini ukugaya i-anealing burn?
I-1) Ukushisa: Uma izinga lokushisa endaweni yokugaya lingadluli izinga lokushisa lokuguqulwa kwensimbi eqinile, kodwa lidlule izinga lokushisa lokushintsha kwe-martensite, i-workpiece surface metal martensite izoguqulwa ibe ubulukhuni obuphansi besakhiwo esithambile.
2) Ukucisha: uma izinga lokushisa endaweni yokugaya lidlula izinga lokushisa lokushintsha kwesigaba, kuhlangene nomphumela wokupholisa we-coolant, insimbi engaphezulu izovela isakhiwo sesibili sokucisha i-martensite, ubulukhuni bungaphezu kwe-martensite yasekuqaleni; Kusendlalelo salo esiphansi, ngenxa yokupholisa kancane, izicubu ezithambile ezinobulukhuni obuphansi kune-martensite yasekuqaleni evelayo.
Ukufaka i-Annealing: Uma izinga lokushisa endaweni yokugaya lidlula izinga lokushisa lokushintsha kwesigaba futhi kungabikho ukupholisa phakathi nenqubo yokugaya, insimbi engaphezulu izoba nesakhiwo esine-anneal futhi ukuqina kwensimbi engaphezulu kuzokwehla kakhulu.
