Ukugaya imisonto kukugqiba ukucola intambo ngoncedo lwe-axis emithathu yonxibelelwano lweziko lomatshini lomatshini kunye ne-G02 okanye i-G03 spiral interpolation command.Indlela yokugaya intambo ngokwayo ineenzuzo ezithile zendalo.
Ngenxa yezinto zangoku zokuvelisa i-thread cutters ye-thread milling ibe yi-alloys enzima, isantya sokucubungula sinokufikelela kwi-80-200m / min, ngelixa i-process speed ye-high-speed steel cones yi-10-30m / min kuphela.Ke ngoko, abasiki bentambo bokugaya intambo bafanelekile ukusika ngesantya esiphezulu kwaye ukugqitywa komphezulu wemicu ecutshungulweyo nako kuphuculwe kakhulu.
I-thread machining yezinto ezinobunzima obuphezulu kunye ne-high-temperature alloy materials, ezifana ne-titanium alloy kunye ne-nickel based alloy, ibisoloko iyingxaki enzima, ngakumbi ngenxa yokuba iicones zentsimbi ezinesantya esiphezulu zinobomi obufutshane besixhobo xa kusenziwa imisonto yezi zinto. .Nangona kunjalo, ukusebenzisa i-hard alloy thread milling cutter yokwenza imisonto yezinto ezinzima sisisombululo esifanelekileyo.Ubulukhuni be-machinability yi-HRC58-62.Ukusetyenzwa komsonto wemathiriyeli ye-alloy yobushushu obuphezulu, abasiki bentambo bokugaya babonisa ukusebenza kakuhle komatshini kunye nobomi obude obungalindelekanga.Kwimingxuma enemisonto enepitshi efanayo kunye needamitha ezahlukeneyo, ukusebenzisa itephu yokucoca kufuna izixhobo ezininzi zokusika ukuze ugqibezele.Nangona kunjalo, ukuba usebenzisa i-thread milling cutter ukwenza umatshini, inye kuphela isixhobo sokusika esinokusetyenziswa.Emva kokuba itephu iphantsi kwaye ubungakanani bentambo esetyenzisiweyo bungaphantsi kokunyamezela, ayinakuphinda isetyenziswe kwaye inokuchithwa kuphela;Xa intambo yokusila cutter inxitywe kunye nobungakanani umngxuma intambo ecutshungulweyo ingaphantsi konyamezelo, oluyimfuneko isixhobo imbuyekezo radius uhlengahlengiso zingenziwa ngokusebenzisa inkqubo CNC ukuqhubeka processing imisonto abafanelekileyo.Ngokufanayo, ukuze ufumane imingxuma ephezulu echanekileyo, usebenzisa i-thread milling cutter ukulungisa i-radius yesixhobo kulula kakhulu kunokuvelisa iimpompo ezichanekileyo.Ukulungiswa komsonto wedayamitha encinci, ngakumbi ubulukhuni obuphezulu kunye nemathiriyeli yobushushu obuphezulu, impompo inokwaphuka ngamanye amaxesha, ivale umngxuma othungelweyo, kwaye ibangele ukuba iindawo zichithwe;Ukusebenzisa intambo yokusila i-cutter, ngenxa yobukhulu obuncinci besixhobo xa kuthelekiswa nomngxuma owenziweyo, nokuba iphukile, ayiyi kubamba umngxuma wentambo yesiseko, okwenza kube lula kakhulu ukuyisusa kwaye ayiyi kubangela ukuba iindawo zikhutshwe;Ngokusebenzisa ukugaya intambo, amandla okusika isixhobo sokusika ancitshiswe kakhulu xa kuthelekiswa nempompo, ebaluleke kakhulu ekwenzeni imicu emikhulu yobubanzi.Oku kusombulula ingxaki isixhobo umatshini ukugcwala kakhulu kwaye ayikwazi ukuqhuba impompo yesiqhelo machining.Umatshini blade blade uhlobo intambo yokusila cutter yaziswa kunyaka ophelileyo, kwaye abantu baye baqaphela ukuba xa machining imingxuma threaded ngasentla M20 kwiziko machining. , usebenzisa intambo yokusika intambo kunokunciphisa kakhulu iindleko zokucubungula xa kuthelekiswa nokusebenzisa impompo.Nangona kunjalo, kwiminyaka yakutshanje, uyilo kunye neteknoloji yemveliso ye-alloy hard thread milling cutters ziye zakhula ngokuthe ngcembe, kwaye uthotho lweemveliso ezinoluhlu olupheleleyo lobukhulu ziye zaphuhliswa.Ukusetyenziswa kwe-machining yentambo ye-diameter encinci, ishishini le-aviation kufuneka liqhube i-50 M1.6 × 0.35 imingxuma yokugaya intambo kwi-aluminium component.Umthengi uhlangabezane nengxaki: ngenxa yembobo eyimfama, ukususwa kwe-chip kunzima, kwaye kulula ukuphuka xa usebenzisa i-tap for machining;Njengoko ukucofa yinkqubo yokugqibela, ukuba inxalenye ilahliwe, ixesha elibalulekileyo lokucubungula elichithwe kwinqanaba liya kulahleka ngokupheleleyo.Ekugqibeleni, umthengi ukhethe i-thread milling cutter yokucubungula iintambo ze-M1.6 × 0.35, kunye nesantya somgca weVc = 25m / min kunye nesantya se-S = 4900r / min (umda womatshini), kunye nesantya sokutya kwe-fz = 0.05 mm/r ngenguquko nganye.Ixesha langempela lokucubungula laliyi-4 imizuzwana ngentambo nganye, kwaye zonke ii-workpieces ze-50 zagqitywa ngesixhobo esinye.
Ishishini elithile lemveliso yesixhobo sokusika, ngenxa yobunzima obuqhelekileyo bomzimba wesixhobo sokusika i-HRC44, kunzima ukusebenzisa iimpompo zocingo zentsimbi ezinesantya esiphezulu ukucubungula imingxunya emincinci enemisonto ecinezela iblade.Ubomi besixhobo bufutshane kwaye kulula ukuqhawula.Ukulungiswa kwentambo ye-M4x0.7, umthengi ukhetha i-carbide thread milling cutter eqinile kunye ne-Vc = 60m / minFz = 0.03mm / r ixesha lokucubungula imizuzwana ye-11 / umsonto, kwaye ubomi besixhobo bufikelela kwiintambo ze-832, kunye nokugqiba intambo egqwesileyo.
Umatshini wokwenza imisonto edayamitha ephakathi kuquka ukusetyenziswa kobukhulu obuthathu obahlukeneyo bemingxuma ephothiweyo, i-M12x0.5, M6x0.5, kunye ne-M7x0.5, kwiindawo ze-aluminiyam eziza kwenziwa ngomatshini lishishini elithile, ngesandi esifanayo.Ngaphambili, iintlobo ezintathu zeetephu bekufuneka ukugqiba umatshini.Ngoku sisebenzisa i-thread milling cutter enemiqathango yokusika: Vc = 100m / min, S = 8000r / min, fz = 0.04mm / r.Ixesha lokucubungula umsonto omnye yimizuzwana emi-4, imizuzwana emi-3, kunye nemizuzwana emi-3 ngokulandelelanayo.Isixhobo esinye sinokuqhuba imisonto engama-9000.Emva kokugqiba yonke ibhetshi yokucutshungulwa kwamalungu, isixhobo asikabonakalisi.
Kumashishini okuvelisa amandla amakhulu kunye nezixhobo zetsimbi, kunye nempompo kunye nemizi-mveliso yevalve, abasiki bentambo bokugaya baye basombulula ingxaki yokucoca imicu emikhulu, ibe sisixhobo esifanelekileyo sokusebenza kunye nexabiso eliphantsi.Umzekelo, iinxalenye ezithile zevalve ezisebenza kwishishini kufuneka ziqhubekise i-2 "x11BSP-30 imisonto eyenziwe ngentsimbi etyhidiweyo kwaye inethemba lokuphucula ukusebenza kakuhle.Ngokukhetha i-multi chip slot kunye ne-multi blade machine clamp yohlobo lokusila intambo yokusila, usebenzisa iiparameters zokusika zeVc=80m/min, S=850r/min, fz=0.07mm/r, ixesha lokucubungula yi-2min/thread, kunye neblade. ubomi ngamaqhekeza angama-620, ngokufanelekileyo ukuphucula ukusebenza kakuhle kwemisonto enkulu yobukhulu.
Abasiki bemisonto, njengesixhobo esiphucukileyo esiphuhliswe ngokukhawuleza kwiminyaka yakutshanje, baya besanda kwamkelwa ngamashishini kwaye babonise ukusebenza kakuhle kokusetyenzwa, baba sisixhobo esinamandla kumashishini ukunciphisa iindleko zokusetyenzwa komsonto, ukuphucula ukusebenza kakuhle, kunye nokusombulula iingxaki zokusetyenzwa komsonto.
