Mndandanda: Chifukwa Chake Ma Drill Bits Amalephera | Nkhani 8
Mawu Ofunika: kuyenda kwa drill bit, kuyendayenda kwa drill bit, kuboola kunja kwa pakati, drill point geometry, chisel edge centering, drill bit runout, dzenje lalikulu
Nkhani zitatu zomaliza mu mndandanda uno zidafotokoza za chithandizo cha kutentha: chifukwa chake kuuma kuli kofunika, chifukwa chake zidutswa zobowola zimasweka kapena kusweka m'malo mowonongeka, ndi momwe ogula angayesere ubwino wa chithandizo cha kutentha m'malo mongotsatira zomwe wogulitsa akunena. Nkhaniyi ikutsegula gulu latsopano mu mndandandawu: geometry. Chithandizo cha kutentha chimasankha zomwe chidutswa chobowola chingapulumuke. Geometry imasankha komwe chikupita.
Akatswiri ambiri a makina aona izi zikuchitika: chobowoleracho chimakhudza pamwamba, ndipo m'malo moluma molunjika pamalopo, nsonga yake imatsetsereka m'mbali kwa kanthawi kochepa isanagwire. Mu shopu, izi zimatchedwa kuyenda - chidutswacho chimachoka pakati pake chisanayambe kudula bwino. Nthawi zambiri chimakhala pang'ono chabe. Cholakwika chomwe chimasiya sichidzikonza chokha.
Nkhaniyi ikufotokoza chifukwa chake kuyenda kumachitika, zomwe zimawonongera wogula pansi, komanso momwe angadziwire ngati chifukwa chake chikugwirizana ndi chobowolera kapena momwe chikuyendetsedwera.
Kodi Kuyenda Kwenikweni N'chiyani - Ndipo Chifukwa Chake Ndi Vuto la Jiometri, Osati La Zinthu Zakuthupi?
Malo obowolera ozungulira si malo enieni. Amapangidwa ndi milomo iwiri yodula ndi m'mphepete mwa chisel womwe umayenda pakati pawo. M'mphepete mwa chisel simudula mwachibadwa - umatulutsa ndikusuntha zinthu patsogolo pa milomo m'malo mozidula bwino. Pamalo oyenera pansi, milomo iwiriyi ndi yofanana kutalika ndi ngodya, ndipo m'mphepete mwa chisel mumakhala pa mzere wa chisel. Pansi pa izi, kukana kwa axial pa milomo yonse kumakhala koyenera, ndipo chisel imalowa molunjika.
Kusinthasintha kumeneko kukangosokonekera — kaya chifukwa cha kulakwitsa kwa kugaya kapena chifukwa cha malire a kapangidwe ka mfundo — milomo iwiriyi sikumananso ndi kukana kofanana. Mphamvu yomwe imabwera imakhala ndi gawo la mbali m'malo mwa lozungulira lokha, ndipo nsonga yake imayenda kupita kumbali yomwe imapereka kukana kochepa mpaka mphamvuzo zitabwereranso, kapena mpaka khoma la dzenjelo litaletsa chingwecho.
Ichi ndichifukwa chake kuyenda kumakhala kokhazikika pafupifupi nthawi yoyamba yokhudza. Bowolo likalowa m'zinthuzo mokwanira kuti m'mphepete mwake mugwire khoma la dzenje, chidutswacho chimakhala cholimba ndipo kuyenda kwa mbali kumasiya. Kuyenda si vuto lopitirira mu kudula - ndi vuto ndi momwe dzenjelo limayambira.
Chimene Chimachititsa Kuti Drill Bit Iyende
1. Utali kapena Ngodya Yosafanana ya Milomo
Ichi ndiye chifukwa chofala kwambiri, ndipo ndichosavuta kuchinyalanyaza ndi maso. Ngati milomo iwiri yodulidwayo imasiyana kutalika kapena ngodya — ngakhale ndi malire ang'onoang'ono — kukana kwa mbali iliyonse sikufanananso. Kusiyana kwakukulu, kuyenda kumaonekera kwambiri.
Cholakwika chamtunduwu chimachokera ku zipangizo zopukutira zomwe sizimaletsa kulekerera kwamphamvu, kapena kuchokera ku njira yopukutira yopanda kuyang'aniridwa mwadongosolo kumbuyo kwake. Milomo iwiri imatha kuwoneka yofanana ndi diso koma imayesabe kunja kwa kulekerera kovomerezeka pansi pa pulojekitala kapena gauge ya point-angle.
2. Mphepete mwa Chisel Yopanda Pakati
Ngati m'mphepete mwa chisel mulibe pakati pa mzere wobowolera, mfundo yake imakhala yosiyana ndi ina iliyonse. Mukakhudza, m'mphepete mwa chisel womwe uli kunja kwa pakati umayambitsa kutsika pang'ono pamene chidutswacho chikuzungulira, zomwe zimawoneka ngati chizindikiro chopindika pamwamba osati ngati cholowera choyera.
3. Palibe Jiometri Yodziyimira Yekha Pamalo Ofunika
Mfundo yokhazikika ya conical ilibe mawonekedwe ake ozungulira - imadalira kwathunthu kugayira kuti ilowe molunjika. Mfundo yogawanika, mosiyana, imawonjezera kugayira kwachiwiri m'mphepete mwa chisel komwe kumasintha chomwe chinali malo otuluka kukhala gawo lalifupi la m'mphepete weniweni, kufupikitsa kwambiri m'mphepete mwa chisel ndikuchepetsa chizolowezi cha kubowola kuyenda. Tikambirana izi mwatsatanetsatane m'nkhani yotsatira mu gulu ili.
4. Mkhalidwe wa Malo Ogwirira Ntchito
Ngakhale malo obowolera ofanana bwino amatha kuyenda ngati pamwamba pake sipakukwanira. Malo otsetsereka kapena opindika, sikelo ya mphero, gawo la oxide, kapena chophimba chosagwirizana zonse zimapangitsa kuti milomo iwiriyi isagwirizane bwino, popanda chilichonse chomwe chili mu mpheroyo. Ichi ndi chikhalidwe cha kugwiritsa ntchito, osati vuto la mtundu wa bit.
5. Kusagwirizana kwa Liwiro ndi Kulimba
Liwiro lopitirira muyeso la spindle, kuchuluka kwa chakudya komwe kumakhala kotsika kwambiri kuti kulowe, kapena kusakhazikika bwino mumakina kapena kugwira ntchito zonse zimatha kuyambitsa kugwedezeka pang'ono kwa radial panthawi yokhudza. Kugwedezeka kokha sikumayambitsa kuyenda - koma kumawonjezera kusalingana komwe kukanakhala kochepa, kusandutsa kulekerera pang'ono kwa kugaya kukhala vuto looneka, lobwerezabwereza.
Kodi Kuyenda Kumawononga Ndalama Ziti kwa Wogula?
Kuyenda n'kosavuta kunyalanyaza ngati chinthu chokongoletsera - chizindikiro cha kusweka, mphindi yokayikira isanagwidwe. Pakupanga, imakhala ndi mitengo itatu yeniyeni.
• Cholakwika pa malo a dzenje.Mukangoyenda pang'ono musanagwire, dzenje lomalizidwa sililinso komwe kumafunika kusindikizidwa. Pa dzenje limodzi izi zitha kugwera mu kulekerera. Pa chitsanzo cha bolt-hole, jig, kapena bracket yomwe iyenera kugwirizana ndi gawo lachiwiri, kuchotsera pang'ono komweko kumaphatikizana pa dzenje lililonse mu chitsanzocho ndipo kumatha kuchotsa gawo labwino kwambiri mu kulekerera konse.
• Mabowo akuluakulu komanso osazungulira.Kanthu kakang'ono kamene kamayenda kasanagwire sikadula njira yozungulira yoyera kuyambira nthawi yoyamba — kamakokedwa, kenako kamakonza, kenako kamadula. Dzenje lomalizidwa limakhala lalikulu kuposa mainchesi odziwika bwino a chobowolera ndipo limatuluka mozungulira, zomwe ndizofunikira kwambiri pakugwiritsa ntchito kulikonse komwe kungagwirizane: ma bushings, ma dowel pini, mabowo okonzedwanso, kapena chilichonse chomwe chimalowa ndi press kapena slip fit.
• Ndalama zomangira ndi kukonzanso.Zomangira zomwe sizimakhala mozungulira, mawonekedwe a bolt omwe sagwirizana pakati pa zigawo zolumikizirana, ndi mabowo omwe amafunika kubooledwanso kuti akhale akuluakulu kuti akonze malo awo - zonsezi zimapangitsa vuto la kuboolera kukhala mtengo wokwera kwambiri, womwe nthawi zonse umakhala wokwera mtengo kwambiri kuposa kuugwira pa kuboolera.
Pa chitsulo chopyapyala komanso chobowoledwa ndi manja, kuyenda kumasiyanso chilonda chooneka pamwamba pozungulira dzenjelo - vuto lokongoletsa mbali zina zomwe mawonekedwe ake ndi ofunika, pamwamba pa lalikulu.
Momwe Ogula Angadziwire Chifukwa Chomwe Akuchita Nacho
Kuyenda kumaoneka chimodzimodzi mosasamala kanthu za chifukwa, koma komwe kumawonekera - komanso pansi pa mikhalidwe iti - nthawi zambiri kumasonyeza komwe vuto lili kwenikweni.
• Ma bits angapo ochokera ku batch walk yomweyo, popanda kusintha momwe akuyendetsedwera.Izi zikusonyeza kugayidwa kwa symmetry kapena chisel-edge centering, ndipo ndikofunikira kukambirana ndi wogulitsayo pamodzi ndi pempho la deta yowunikira mfundo.
• Kuyenda kumachitika kokha popanda chizindikiro chapakati kapena dzenje loyesera.Izi mwina ndi vuto la momwe zinthu zilili pa ntchito kuposa vuto la kubowola. Malo obowola ozungulira amadalira kusinthasintha kwa kugaya kuti alowe pakati, ndipo kuyenda kwina popanda wotsogolera ndi khalidwe loyembekezeredwa, osati chizindikiro cha chidutswa cholakwika.
• Kuyenda kumachitika pamalo okhota, opindika, kapena okhala ndi mamba okha, osati pamalo osalala komanso oyera.Izi zikusonyeza pamwamba pa workpiece, osati mawonekedwe a drill.
• Chobowola chomwecho chimayenda bwino kwambiri pa liwiro limodzi la spindle kuposa lina.Izi zikusonyeza kuti kugwedezeka kapena kulimba kwa chipangizocho kukuwonjezera kusiyana pang'ono, ndipo ndikofunikira kuyang'anitsitsa momwe ntchito ikuyendera komanso momwe imagwirira ntchito musanaganize kuti chipangizocho chili ndi vuto.
Kusiyanaku n'kofunika chifukwa kukonza kumakhala kosiyana pazochitika zonse ziwiri. Vuto logaya kapena lokhazikika ndi vuto la kupanga lomwe limafuna kukambirana ndi wogulitsa. Vuto la momwe zinthu zilili limafunika kumenyedwa pakati, dzenje loyesera, kapena kusintha liwiro - palibe kuchuluka kwa mabowo obwezeredwa komwe kungakonze vutoli. Kuona awiriwa ngati vuto lomwelo nthawi zambiri kumatanthauza kuti chifukwa chenicheni sichidzathetsedwa.
Zokhudza mndandanda uwu
Chifukwa Chake Drill Bits Fail ndi mndandanda waukadaulo wolembedwa ndi gulu lathu lopanga. Nkhani iliyonse imayang'ana kwambiri chinthu chimodzi chomwe chimagwira ntchito bwino pa drill bit - kuyambira pazinthu zopangira mpaka kulongedza. Cholinga chake ndi chosavuta: kuthandiza ogula kumvetsetsa zomwe akugula, komanso mafunso oti afunse.
