Ukugaya intambo ukuqedela ukugaya intambo ngosizo lomsebenzi wokuxhumanisa ama-eksisi amathathu wesikhungo somshini we-CNC kanye nomyalo we-G02 noma we-G03 wokuhumusha okuvunguzayo.Indlela yokugaya intambo ngokwayo inezinzuzo ezithile zemvelo.
Ngenxa yezinto zamanje zokukhiqiza zezinqamuleli zokugaya intambo ama-alloys aqinile, isivinini sokucubungula singafinyelela ku-80-200m/min, kuyilapho isivinini sokucubungula sezigaxa zezintambo zensimbi ezinesivinini esiphezulu singu-10-30m/min kuphela.Ngakho-ke, abasiki bezintambo bezintambo bafanele ukusika ngesivinini esiphezulu futhi ukuqedwa okungaphezulu kwezintambo ezicutshunguliwe nakho kuthuthukiswa kakhulu.
Ukwenziwa kwentambo yezinto ezinobulukhuni obuphezulu nezinto ezisezingeni eliphezulu zengxubevange, njenge-titanium alloy ne-nickel based alloy, bekulokhu kuyinkinga enzima kakhulu, ikakhulukazi ngoba izigaxa zensimbi ezinesivinini esikhulu zinempilo yethuluzi elifushane lapho kwenziwa imicu yalezi zinto. .Kodwa-ke, ukusebenzisa i-hard alloy thread milling cutter yokwenza izintambo zezinto eziqinile kuyisixazululo esihle.Ubulukhuni be-machinability yi-HRC58-62.Ukuze kucutshungulwe intambo yezinto ezisezingeni eliphezulu zengxubevange, izisiki zokugaya intambo nazo zikhombisa ukusebenza kahle komshini nempilo ende engalindelekile.Ngezimbobo ezinentambo ezinephimbo elifanayo nobubanzi obuhlukile, ukusebenzisa umpompi wokwenza imishini kudinga amathuluzi okusika amaningi ukuze kuqedwe.Kodwa-ke, uma usebenzisa i-thread milling cutter yokwenza imishini, ithuluzi lokusika elilodwa kuphela elingasetshenziswa.Ngemuva kokuthi umpompi uphansi futhi usayizi wentambo ocutshunguliwe ungaphansi kokubekezelelana, ngeke usakwazi ukusetshenziswa futhi ungachithwa kuphela;Uma i-thread milling cutter igugile futhi nosayizi wembobo yentambo ecutshunguliwe ingaphansi kokubekezelelana, ukulungiswa kwesinxephezelo se-radius yethuluzi elidingekayo kungenziwa ngohlelo lwe-CNC ukuze kuqhutshekwe nokucubungula imicu efanelekile.Ngokufanayo, ukuze uthole izimbobo ezinentambo ezinembayo, ukusebenzisa i-thread milling cutter ukulungisa i-radius yethuluzi kulula kakhulu kunokukhiqiza ompompi abanemba okuphezulu.Ukuze kucutshungulwe intambo yobubanzi obuncane, ikakhulukazi ngobulukhuni obuphezulu kanye nezinto ezisezingeni eliphezulu, umpompi ngezinye izikhathi ungase uphuke, uvimbe imbobo enentambo, futhi ubangele nokuthi izingxenye zichithwe;Ukusebenzisa i-thread milling cutter, ngenxa yobubanzi obuncane bethuluzi uma kuqhathaniswa nomgodi ocutshungulwayo, noma ngabe iphukile, ngeke ivimbele imbobo yentambo yesisekelo, okwenza kube lula kakhulu ukuyisusa futhi ngeke ibangele ukuba izingxenye zikhishwe;Ngokusebenzisa ukugaya intambo, amandla okusika ethuluzi lokusika ancishiswa kakhulu uma kuqhathaniswa nompompi, okubaluleke kakhulu ekwenzeni imicu emikhulu yobubanzi.Lokhu kuxazulula inkinga yokuthi ithuluzi lomshini lilayishwa ngokweqile futhi alikwazi ukushayela umpompi ukuze lisetshenziswe ngendlela evamile.Isisiki sokugaya intambo yomshini wensimbi yocingo yethulwa ngonyaka odlule, futhi abantu baye baqaphela ukuthi lapho kwenziwa izimbobo ezinentambo ngaphezu kuka-M20 esikhungweni somshini. , ukusebenzisa i-thread milling cutter kunganciphisa kakhulu izindleko zokucubungula uma kuqhathaniswa nokusebenzisa umpompi.Kodwa-ke, eminyakeni yamuva nje, ubuchwepheshe bokuklama nokukhiqiza abasiki be-hard alloy thread milling cutters buye bavuthwa kancane kancane, futhi uchungechunge lwemikhiqizo enobubanzi obuphelele bosayizi senziwe.Ukuze kusetshenziswe intambo encane yomshini womshini, inkampani yezindiza idinga ukucubungula izimbobo zokumba intambo engu-50 M1.6×0.35 engxenyeni ye-aluminium.Ikhasimende lihlangabezane nenkinga: ngenxa yembobo eyimpumputhe, ukukhishwa kwe-chip kunzima, futhi kulula ukuphuka uma usebenzisa umpompi womshini;Njengoba ukuthepha kuyinqubo yokugcina, uma ingxenye ilahliwe, isikhathi esibalulekile sokucubungula esichithwe engxenyeni sizolahleka ngokuphelele.Ekugcineni, ikhasimende likhethe isisiki sokugaya intambo ukuze sicubungule imicu engu-M1.6×0.35, enesivinini somugqa esingu-Vc=25m/min kanye nesivinini esingu-S=4900r/min (umkhawulo womshini), kanye nesilinganiso sokuphakelayo esingu-fz=0.05 mm/r inguquko ngayinye.Isikhathi sangempela sokucubungula sasiyimizuzwana emi-4 intambo ngayinye, futhi zonke izingcezu zokusebenza ezingama-50 zaqedwa ngethuluzi elilodwa.
Ibhizinisi elithile lokukhiqiza ithuluzi lokusika, ngenxa yokuqina okuvamile kwethuluzi lokusika eliyi-HRC44, kunzima ukusebenzisa ompompi bezintambo zensimbi ezinesivinini esikhulu ukucubungula izimbobo ezinentambo ezinobubanzi obuncane ezicindezela inkaba.Impilo yamathuluzi ifushane futhi kulula ukuphuka.Ngokucubungula intambo engu-M4x0.7, ikhasimende likhetha isisiki esiqinile sokugaya intambo ye-carbide ene-Vc=60m/minFz=0.03mm/r isikhathi sokucubungula samasekhondi angu-11/uchungechunge, futhi ukuphila kwethuluzi kufinyelela emicu engu-832, enokuphela kwentambo enhle kakhulu.
Ukukhanda intambo enobubanzi obumaphakathi kuhilela ukusetshenziswa kosayizi abathathu abahlukene bezimbobo ezinentambo, i-M12x0.5, M6x0.5, ne-M7x0.5, ezingxenyeni ze-aluminium ezizokwenziwa umshini inkampani ethile, enephimbo elifanayo.Ngaphambilini, kwakudingeka izinhlobo ezintathu zompompi ukuze kuqedelwe umshini.Manje sisebenzisa intambo yokugaya enezimo zokusika: Vc=100m/min, S=8000r/min, fz=0.04mm/r.Isikhathi sokucubungula sochungechunge olulodwa amasekhondi angu-4, amasekhondi angu-3, namasekhondi angu-3, ngokulandelana.Ithuluzi elilodwa lingacubungula imicu engu-9000.Ngemva kokuqeda lonke iqoqo lokucutshungulwa kwezingxenye, ithuluzi alikalimele kuze kube manje.
Ezimbonini ezinkulu zokukhiqiza amandla kanye nezimboni zensimbi, kanye nezimboni zokucubungula iphampu nama-valve, abasiki bezintambo baxazulule inkinga yokwenza izintambo ezinkulu zobubanzi, zibe ithuluzi elihle lomshini elisebenza kahle kakhulu kanye nezindleko eziphansi.Isibonelo, inkampani ethile ecubungula izingxenye zevalvu idinga ukucubungula imicu engu-2 “x11BSP-30 eyenziwe ngensimbi esakazwayo futhi inethemba lokuthuthukisa ukusebenza kahle kokucubungula.Ngokukhetha i-multi chip slot kanye ne-multi blade machine clamp yohlobo lokusika intambo yokugaya, kusetshenziswa imingcele yokusika ye-Vc=80m/min, S=850r/min, fz=0.07mm/r, isikhathi sokucubungula yi-2min/thread, kanye neblade. Impilo iyizingcezu ezingama-620, ithuthukisa ngempumelelo ukusebenza kahle kochungechunge olukhulu lobubanzi.
Abasiki bezintambo, njengethuluzi elithuthukisiwe elithuthuke ngokushesha eminyakeni yamuva, baya ngokuya bemukelwa amabhizinisi futhi babonisa ukusebenza kahle kokucubungula, okuba yisikhali esinamandla samabhizinisi sokunciphisa izindleko zokucubungula intambo, ukuthuthukisa ukusebenza kahle, nokuxazulula izinkinga zokucubungula intambo.
