Drill bit ndi mtundu wa zida zomwe zimagwiritsidwa ntchito kwambiri pamakina athu omanga.Amagwiritsidwa ntchito pobowola mabowo kapena mabowo osawona pazinthu zolimba, ndipo amatha kukulitsa mabowo omwe alipo.
Komabe, mitundu ya ma kubowola omwe timasankha ndi yosiyana m'malo osiyanasiyana ogwiritsira ntchito.Zobowola zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo kubowola mopotoka, kubowola kwa lathyathyathya, kubowola pakati, kubowola kwakuya ndi kubowola zisa.
Ndiye ndi kubowola kotani komwe kumagwiritsidwa ntchito pobowola zitsulo?
Kuthamanga kwachitsulo pang'ono kumalimbikitsidwa pobowola zitsulo mbale.
Kuonjezera apo, pobowola, zimatengera kukula kwa dzenje.Ngati dzenjelo ndi lalikulu, mphamvu ya kubowola magetsi yomwe ikufunika kugwiritsidwa ntchito idzakhala yokulirapo.
Tsopano pali chobowola chachitsulo chapadera (chomwe chimatchedwanso hollow drill bit kapena Annular cutter kapena broach cutter kapena core drill or core cutter ), chomwe chimatha kubowola mwachangu kwambiri.
Ndodo yolumikizira imatha kuyikidwa mwachindunji pa kubowola kwa maginito, ndipo mbale zachitsulo zokulirapo za 20 mm zimatha kubowoleredwa mumasekondi ochepa chabe.Lili ndi ubwino woonekeratu
Kubowola kwachitsulo kumatha kugawidwa kukhala zitsulo zothamanga kwambiri (HSS) ndi cemented carbide core drill (TCT) malinga ndi zomwe zili.
Mau oyamba a High Speed Steel Plate Drill(HSS core drill):
Mkulu liwiro zitsulo njanji zitsulo anatengera, ndi mitundu iwiri ya muyezo mtundu ndi youma chonyowa mtundu;Ndi mitundu yosiyanasiyana ya zogwirira ntchito, geometry yovomerezeka ya mano, mapangidwe olekanitsa chip, okhazikika komanso odalirika.
The awiri ranges kuchokera 12mm kuti 36mm, ndi kuya ndi 25mm ndi 50mm;
Chiyambi cha kubowola zitsulo za carbide (TCT core drill):
Mtundu wogwirizira wa kubowola kwamtundu wapadziko lonse lapansi waphimbidwa mokwanira, ndipo m'mimba mwake mwazomwe zimayambira 11mm mpaka 150mm.Kudula kwakuya ndi 35mm, 50mm, 75mm, 100mm, 150mm;
The awiri awiri a mndandanda makonda ndi 200mm, ndi pazipita kudula kuya ndi 200mm;
Imatengera tsamba la carbide lopangidwa ndi simenti yapamwamba kwambiri yokhala ndi tinthu tating'onoting'ono, tolimba, osamva kuvala, komanso kukana kwambiri.Tsambalo limamangirizidwa mwamphamvu ndi chitsimikizo cha moyo wokhazikika;Mapangidwe atatu osanjikiza a tsamba la geometric amawonetsa bwino mawonekedwe amphamvu yaing'ono yodulira komanso kuyika bwino pakati;
Chiyambi cha Hollow Drill Shank Type:
Posankha kubowola kwa dzenje ndi kukula koyenera, mtundu wa ndodo uyenera kusankhidwa molingana ndi chitsanzo cha kubowola kwa maginito.
Mitundu yogwirira ntchito imaphatikizapo mitundu 8: chogwirira cha ngodya yakumanja, chogwirira chambiri, chogwirira cha mabowo anayi, chogwirira chozungulira, chogwirira cha ulusi, chogwirira chamtundu wa P, chogwirira cha mabowo atatu, ndi chogwirira chodula.
Chiyambi cha Twist Drill:
Kuphatikiza apo, zobowola wamba zimathanso kubowola kudzera m'mbale zachitsulo.
Twist kubowola ndiye chida chomwe chimagwiritsidwa ntchito kwambiri popanga dzenje.
Zinthu zake nthawi zambiri zimakhala zitsulo zothamanga kwambiri kapena aloyi yolimba.
Amagwiritsidwa ntchito kwambiri pobowola makina, ma lathes, kubowola pamanja pamagetsi ndi zida zina zamakina pokonza ma diameter osiyanasiyana a dzenje.
Ma twist drill nthawi zambiri amagawidwa m'mabowo opindika a shank ndi cone shank twist.
Kubowola kolunjika kwa shank: koyenera kubowola dzenje laling'ono pansi pa 13.0mm, kondomu kapena taper shank twist kubowola: koyenera kumabowo okhala ndi dzenje lalikulu ndi torque.
Twist kubowola ndiye chida chomwe chimagwiritsidwa ntchito kwambiri pamabowo.Nthawi zambiri, m'mimba mwake kuyambira 0.25 mpaka 80 mm.
Amapangidwa makamaka ndi gawo logwirira ntchito ndi chogwirira.Pali ma grooves awiri ozungulira mu gawo logwira ntchito, lomwe limawoneka ngati kupindika, chifukwa chake amatchedwa.
Pofuna kuchepetsa kukangana pakati pa gawo lowongolera ndi khoma la dzenje pobowola, kukula kwa chobowoleracho kumachepa pang'onopang'ono kuchokera ku nsonga ya kubowola kupita ku shank, ndipo kumakhala kofanana ndi kondomu yopindika.Kubowola kwa helix kumakhudza makamaka kukula kwa ngodya yokhotakhota pamphepete, kulimba kwa tsamba la tsamba ndi ntchito yochotsa chip, nthawi zambiri 25 ° ~ 32 °.Spiral groove imatha kuphwanyidwa ndikuyika pansi.
Kumapeto kwa kutsogolo kwa kubowola kumapukutidwa kuti apange gawo lodula ndi kugudubuza kotentha kapena kutulutsa kotentha.Pamwamba pa gawo lodulira la kubowola kokhazikika ndi 118, mbali ya oblique ya m'mphepete mwake ndi 40 ° ~ 60 °, ndipo mbali yakumbuyo ndi 8 ° ~ 20 °.
Chifukwa cha zifukwa zamapangidwe, mbali yakutsogolo ndi yayikulu pamphepete mwakunja ndipo imatsika pang'onopang'ono kupita pakati.
Mphepete mwa mtanda uli ndi mbali yolakwika yakutsogolo (mpaka - 55 °), yomwe imakhala ngati extrusion pakubowola.Pofuna kupititsa patsogolo ntchito yodula ya twist drill, gawo lodulira limatha kupangidwa mosiyanasiyana malinga ndi momwe zinthu zikugwiritsidwira ntchito (monga kubowola gulu).Ma twist drill ali ndi mitundu iwiri ya shank: shank yowongoka ndi taper shank.Yoyambayo imamangiriridwa mu chuck chobowola pomwe chomalizacho chimayikidwa mu dzenje la spindle kapena tailstock ya chida cha makina.
Nthawi zambiri, zokhotakhota zimapangidwa ndi chitsulo chothamanga kwambiri.Zobowola zokhotakhota zokhala ndi zoyikapo simenti kapena akorona ndizoyenera kukonza chitsulo, chitsulo cholimba komanso zinthu zopanda zitsulo.Zobowola zopindika za Integral cemented carbide zimagwiritsidwa ntchito pokonza zida ndi ma board osindikizidwa.
Chiyambi cha Step Core Drill:
Kubowola kwa Step core, komwe kumadziwikanso kuti step drill kapena pagoda kubowola, kumagwiritsidwa ntchito kwambiri pobowola zitsulo zopyapyala mkati mwa 3mm.
Kubowola kumodzi kungagwiritsidwe ntchito m'malo mobowola kangapo.Mabowo okhala ndi ma diameter osiyanasiyana amatha kukonzedwa momwe amafunikira, ndipo mabowo akulu amatha kukonzedwa nthawi imodzi osasintha mabowo obowola ndi kubowola.
Malinga ndi mawonekedwe a groove a mankhwalawa, amatha kugawidwa kukhala groove yowongoka, spiral groove ndi groove yozungulira;
Pakali pano, pobowola sitepe lonse amapangidwa ndi CBN zonse akupera, makamaka opangidwa ndi mkulu-liwiro zitsulo, aloyi zolimba, etc., ndi mkulu zofunika kulondola processing.Malinga ndi zinthu zosiyanasiyana processing, ❖ kuyanika pamwamba akhoza kuchitidwa kutalikitsa moyo chida ndi kumapangitsanso durability chida.
Zobowola masitepe athu amapangidwa ndi chitsulo cholimba kwambiri chothamanga kwambiri.
The mankhwala awiri osiyanasiyana kuchokera 4mm kuti 40mm.
Kuphatikiza kwa masitepe kumayambira 4 mpaka 13.
Pali mitundu iwiri ya ma groove ozungulira komanso mikwingwirima yowongoka.
Yoyenera kubowola ndi kukonzanso zitsulo, chitsulo choponyedwa, chitsulo chosapanga dzimbiri ndi zipangizo zina;
Mwatsatanetsatane akupera ndi zipangizo basi;Njira yokutira ikhoza kusankhidwa.
Choncho, n'kofunikanso kusankha bwino kubowola pang'ono pobowola zitsulo mbale.
Koma musadandaule.Ngati muli ndi mafunso, chonde omasuka kulankhula nafe.
Ndife okonzeka nthawi zonse kuyankha mafunso aliwonse kwa inu.
Tili ndi akatswiri gulu utumiki ndi kupanga gulu.Ziribe kanthu kuti mumayitanitsa kukula kwanthawi zonse kapena mukufuna kusintha mwamakonda anu, tidzakupatsirani mautumiki osiyanasiyana oganizira.
Takulandilani ku funso lanu nthawi iliyonse!
