I-Carbide blade ukuguga kanye nokusika umphetho kuyizinto ezivamile. Lapho i-carbide blade igqoka, ithinta ukunemba kokucubungula i-workpiece, ukusebenza kahle kokukhiqiza, ikhwalithi ye-workpiece, njll; lapho umqhubi ebona ukuguga kwe-blade, kufanele aphendule ngokushesha enkingeni. Inqubo yomshini ihlaziywa ngokucophelela ukuze kutholakale izimbangela zokugqoka kwe-blade. Ingahlaziywa kusukela ezicini ezilandelayo:
1. Ukugqokwa kwe-flank surface
I-flank wear ibhekisela ekulahlekeni kokuhuzuka kwe-flank yethuluzi ngaphansi konqenqema lokusikwa kwe-carbide futhi eduze kwayo ngokushesha; izinhlayiya ze-carbide ku-workpiece material noma i-work-hard material ihlikihla ngokufaka, nezingcezu ezincane ze-Coating peeling kanye ne-blade friction; isici se-cobalt ku-carbide blade ekugcineni sihlukana ne-crystal lattice, sinciphisa ukunamathela kwe-carbide futhi kubangele ukuba icwecwe.
Indlela yokwahlulela ukugqoka kwe-flank? Kukhona ukugqokwa okufana okufanayo ngasemngceleni wokusika, futhi ngezinye izikhathi izinto ezicwecwayo zokusebenza zinamathela onqenqemeni lokusika, okwenza indawo egugile ibonakale inkulu kunendawo yangempela; amanye ama-alloy blades avela amnyama ngemva kokugqoka, kanti amanye ama-blade abonakala ecwebezela ngemva kokugqoka. Bright; umnyama ungqimba olungezansi noma isisekelo se-blade esivezwa ngemuva kokuthi uqweqwe olungaphezulu luyaxebuka.
Izinyathelo zokuphikisa zihlanganisa: okokuqala ukuhlola isivinini sokusika, ukubala kabusha isivinini sokujikeleza ukuze uqinisekise ukunemba kwayo, nokunciphisa isivinini sokusika ngaphandle kokushintsha okuphakelayo;
Okuphakelayo: Khulisa ukudla ngezinyo ngalinye (isiphakeli kufanele sibe phezulu ngokwanele ukugwema ukuguga okubangelwa ukujiya kwensimbi encane);
I-Blade material: Sebenzisa i-blade engagugi kakhulu. Uma usebenzisa i-blade engagcotshiwe, sebenzisa i-blade eboshiwe esikhundleni salokho; hlola i-blade geometry ukuze unqume ukuthi icutshungulwa ekhanda lokusika elihambisanayo.
2. Unqenqema oluphukile
I-Flank chipping yisimo esidala ukwehluleka kokufaka lapho izinhlayiya ezincane zonqenqema zivuleka kunokuba zihuzuzwe ukugqokwa kweflank. Ukucutshungulwa kwe-flank kwenzeka uma kukhona izinguquko emithwalweni yomthelela, njengokusikeka okuphazamisekile. I-flank chipping ngokuvamile iwumphumela wezimo ezingazinzile, njengalapho ithuluzi lilide kakhulu noma ucezu lokusebenza lungasekelwa ngokwanele; ukusika kwesibili kwama-chip nakho kungabangela ukuchotshozwa kalula. Izinyathelo eziphikisanayo zifaka: ukunciphisa ubude be-protrusion yethuluzi kube inani eliphansi; ukukhetha ithuluzi eline-angle yokusiza enkulu; ukusebenzisa ithuluzi elinomphetho oyindilinga noma onama-chamfered; ukukhetha into eqinile yokusika ithuluzi; ukunciphisa isivinini sokudla; Ukwandisa ukuzinza kwenqubo; thuthukisa umphumela wokususwa kwe-chip nezinye izici eziningi. I-Rake face spalling: Izinto ezinamathelayo zingabangela ukubuya kwempahla ngemva kokusikwa, okungase kudlulele ngale kwe-engeli yokusiza yethuluzi futhi kudale ukungqubuzana phakathi kwendawo yeflank yethuluzi kanye nendawo yokusebenza; ukungqubuzana kungabangela umphumela wokupholisha okungenzeka Kungaholela ekusebenzeni ukuqina kwe-workpiece; izokwandisa ukuthintana phakathi kwethuluzi nomsebenzi, okuzokwenza ukushisa kubangele ukwanda okushisayo, kubangele ukunwebeka kobuso, okuholela ekuqhekekeni kobuso bereki.
Izinyathelo zokulwa zihlanganisa: ukwandisa i-engeli ye-rake yethuluzi; ukunciphisa usayizi wokuzungeza onqenqemeni noma ukwandisa amandla onqenqemeni; nokukhetha izinto ezinokuqina okuhle.
3. Indawo emaphethelweni e-rake blade
Lapho kwenziwa imishini ethile yezinto zokusebenza, unqenqema lweraki lungenzeka phakathi kwe-chip nonqenqema lokusika; unqenqema olwakhiwe lwenzeka lapho ungqimba oluqhubekayo lwempahla yokusebenza i-laminated onqenqemeni lokusika. Unqenqema olwakhiwe luyisakhiwo esiguquguqukayo esisika Indawo enqunyiwe yonqenqema olwakhiwe iyaqhubeka nokuxebuka futhi ixhume kabusha phakathi nenqubo. Unqenqema lwangaphambili luvame ukwenzeka ngezikhathi ezithile emazingeni okushisa aphansi okucubungula kanye nesivinini sokusika esihamba kancane; isivinini sangempela sonqenqema lwangaphambili sincike ezintweni ezicutshungulwayo. Uma izinto eziqinisiwe zomsebenzi zicutshungulwa, njenge-austenitic Uma umzimba wenziwe ngensimbi engagqwali, khona-ke unqenqema lwendawo ye-rake lungabangela ukunqwabelana okusheshayo ekujuleni kokusikwa, okuholela ekuhlulekeni kwesibili kwemodi yokulimala ekujuleni kokusika.
Izinyathelo zokulwa zihlanganisa: ukwandisa isivinini sokusika indawo; ukuqinisekisa ukusetshenziswa okufanele kwesipholisi; nokukhetha amathuluzi ane-physical vapor deposition (PVD) coating.
4. Unqenqema olwakhiwe phezu kwe-flank blade
Kungenzeka futhi endaweni ye-flank ngaphansi komkhawulo wokusika wethuluzi. Lapho usika i-aluminium ethambile, ithusi, ipulasitiki, nezinye izinto, unqenqema lwe-flank lubangelwa nokungatholakali okwanele phakathi kwendawo yokusebenza kanye nethuluzi; ngesikhathi esifanayo, i-flank edge Nodules ihlotshaniswa nezinto ezihlukene zokusebenzisa. I-workpiece ngayinye idinga inani elanele lokuvunyelwa. Ezinye izinto zokusebenza, njenge-aluminium, ithusi, nepulasitiki, zizophindela emuva ngemva kokusika; i-spring back ingabangela ukungqubuzana phakathi kwethuluzi kanye ne-workpiece, okubangela ukuthi ezinye izinto zokucubungula zihlangane. I-flank enqenqemeni.
Izinyathelo zokuphikisa zihlanganisa: ukwandisa i-engeli yokusiza eyinhloko yethuluzi; ukwandisa isivinini sokudla; kanye nokunciphisa ukuzungezisa onqenqemeni okusetshenziselwa ukwelapha kwangaphambili.
5. Imifantu eshisayo
Imifantu eshisayo ibangelwa izinguquko ezimbi kakhulu ekushiseni; uma ukusika kuhilela ukusika ngezikhathi ezithile njengokugaya, unqenqema lokusika luzongena futhi luphume ezintweni zokusebenza izikhathi eziningi; lokhu kuzokwandisa futhi kunciphise ukushisa okumuncwe ithuluzi, futhi izinguquko eziphindaphindiwe kuzinga lokushisa zizobangela ukunwetshwa nokufinyela kwezingqimba zangaphezulu zamathuluzi njengoba zishisa ngesikhathi sokusika futhi zipholisa phakathi kokusikeka; lapho okokupholisa kungasetshenziswa ngendlela efanele, okokupholisa kungase kubangele ushintsho olukhulu lokushisa, kusheshise ukuqhekeka okushisayo, futhi Ibangela ithuluzi ukuthi lihluleke ngokushesha. Izinga lokushisa lidlala indima ebalulekile empilweni yamathuluzi nasekuhlulekeni kwamathuluzi; imifantu eshisayo iwukubonakaliswa kokuqhekeka kwe-rake ne-flank enqenqemeni yokusika. Isiqondiso sabo sisema-engeli alungile onqenqemeni lokusika. Imifantu iqala endaweni eshisa kakhulu endaweni ye-rake, ngokuvamile iqhelelene nonqenqema lokusika. Kunebanga elincane phakathi kwamaphethelo, bese lidlulela ebusweni be-rake nangaphezulu ebusweni bohlangothi; imifantu eshisayo ebusweni bereki naseceleni ekugcineni kuyaxhunywa, okuholela ekuqhekekeni kobuso obuseceleni bonqenqema lokusika.
Izinyathelo zokulwa zihlanganisa: ukukhetha izinto zokusika eziqukethe izinto eziyisisekelo ze-tantalum carbide (TAC); ukusebenzisa isipholile ngendlela efanele noma ungasisebenzisi; ukukhetha izinto eziqinile zokusika, njll.
