Mndandanda: Chifukwa Chake Ma Drill Bits Amalephera | Nkhani 6
Mawu Ofunika: kuthyola bit, kusweka kwa drill bit, kulephera kwa drill bit, kulimba kwa drill bit, khalidwe la drill bit kutentha, kuthyola bit drill, kukhazikika kwa drill bit
Mu nkhani yathu yapitayi, tinaona chifukwa chake kuuma (HRC) n'kofunika pa khalidwe la HSS drill bit - komanso chifukwa chake kuuma kwakukulu sikumakhala bwino nthawi zonse. Bokosi lolimba kwambiri koma losakwanira silimangotha msanga. Limalephera mwanjira ina: mwa kudula kapena kusweka, osati chifukwa cha kuwonongeka pang'onopang'ono komanso kodziwikiratu.
Nkhaniyi ikuyang'ana mwachindunji njira yolephera imeneyo. N'chifukwa chiyani mabowo amasweka kapena kusweka m'malo mowonongeka momwe akuyenera kukhalira? Ndi limodzi mwa mafunso omwe amaiwalika kwambiri pamene ogula amayesa kupeza chomwe chalakwika - ndipo ndani ali ndi udindo wokonza.
Njira ziwiri zosiyana kwambiri zomwe Drill Bit ingalephere
Kulephera kwa kubowola kumagwera m'magulu awiri, ndipo kumachokera ku njira ziwiri zosiyana zamakina.
Zovala Zachizolowezi
Iyi ndi njira yolephera yomwe wogula aliyense akufuna kuwona. Mphepete mwa njira zamakono zimachepa pang'onopang'ono pamene zinthuzo zikuwonongeka mofanana, panthawi yonse yogwiritsidwa ntchito. Zimakhala zodziwikiratu komanso zodziwika bwino — ogula amatha kuwerengera nthawi yomwe idzakhalepo ndikukonzekera kusintha kwa chida moyenerera. Palibe zodabwitsa.
Kusweka kapena Kuduladula
Iyi ndi njira yolephera yomwe wogula aliyense akufuna kupewa. Gawo laling'ono la m'mphepete mwamakono limasweka mwadzidzidzi, kapena chobowola chonsecho chimasweka. Izi sizikutanthauza kuti chinthucho chikuwonongeka — koma chimawonongeka mwadzidzidzi pamene mphamvu yomwe chili nayo ikupitirira zomwe chingathe kupirira.
Kulephera kwamtunduwu nthawi zambiri sikupereka chenjezo. Chobowola chingadule nthawi zina kenako nkuchigwetsanso - nthawi zina chimachotsa chogwiriracho.
Kumvetsetsa kusiyana kumeneku n'kofunika chifukwa kusweka ndi kusweka sikumachitika kawirikawiri chifukwa cha zinthu zomwezo zomwe zimapangitsa kuti kuwonongeka kwabwinobwino kuchitike mwachangu. Ziyenera kuzindikirika padera.
Zifukwa Zitatu Zomwe Zimayambitsa Kusweka ndi Kugwa
1. Zolakwika Zokhudza Kutentha: Chobowola Chomwe Chayamba Kuphwanyika
Kulimba kwa chobowola chimachokera pafupifupi ku kutentha kokha, osati ku chitsulo chosaphika chokha.
Pambuyo pozimitsa, HSS imapanga kapangidwe ka martensitic komwe kali kolimba kwambiri komanso kolimba kwambiri. Ngati kutenthetsa sikukwanira - kapena kudulidwa, kapena kusalamulirika bwino - chobowola pang'ono chimatha kuyeza kuchuluka kwa kuuma kodabwitsa pamene chikunyamulabe kufooka kwa mkhalidwe womwe wazimitsidwa, popanda kuthekera konse koyamwa kugwedezeka. Chobowola pang'ono ngati ichi chidzaphwanyika ngakhale pang'ono kapena kudula kosalekeza.
Vuto lina lofanana ndi limeneli ndi kusalamulira bwino kutentha kwa chozimitsira moto. Ngati kutentha kwa chozimitsira moto kukukwera kwambiri, kumakwinya kapangidwe ka tinthu tating'onoting'ono ndipo kumasiya austenite yosakhazikika mu kapangidwe kake. Zotsatira zake zonse zimachepetsa kulimba ndipo zimawonjezera chiopsezo cha ming'alu, nthawi yozimitsira moto komanso pambuyo pake ikagwiritsidwa ntchito.
Palinso njira yolephera yomwe ogula nthawi zambiri samaidziwa konse: chidutswa chobowola chomwe chimalimba mpaka kufika pa nambala yomweyo kuchokera ku nsonga mpaka ku tsinde.
Chobowolera cha HSS chosinthidwa bwino sichikhala ndi kuuma kofanana kutalika kwake. Malo odulira amafunika kukhala olimba mokwanira kuti agwire m'mphepete ndikupewa kuwonongeka. Chobowoleracho chimayenera kukhala cholimba mokwanira kuti chipulumuke mphamvu yomangirira ndi kugwedezeka kwa chuck. Wogulitsa akalimbitsa thupi lonse kukhala nambala imodzi yapamwamba, chimawoneka ngati chinthu chapamwamba poyamba - cholimba kulikonse. Mwachizolowezi, chobowoleracho chataya kulimba komwe chimafunikira, ndipo chobowoleracho chimakhala chosweka mwadzidzidzi komanso chophwanyika pa shank pansi pa katundu wolemera. Ichi ndi mfundo yomweyi kuchokera m'nkhani yathu yapitayi, yomwe yatengedwa sitepe imodzi patsogolo: kuuma kwakukulu, kugwiritsidwa ntchito pamalo olakwika, sikupanga chobowolera chabwino.
2. Zinthu Zodula Zomwe Zimapangitsa Kuti Mphepete Mwa Mphepete Mukhale Modzaza
Ngakhale kuti zinthu ndi kutentha zonse zili bwino, momwe chobowolera chimagwiritsidwira ntchito chingayambitse kusweka. Mavuto ofala ndi awa:
• Kudula kosokonekera— pamene chobowolera chilowa kapena kutuluka pamalo opingasa, pa dzenje lopingasa, kapena pa msoko wothira, katundu womwe uli m'mphepete mwake umakhala wosakhazikika kwakanthawi, zomwe zimapangitsa kuti katundu wogwedezeka ukhale woposa mphamvu zodulira zomwe zimagwiritsidwa ntchito nthawi zonse.
• Kuchuluka kwa chakudya cha ziweto kumakhala kochepa kwambiri pa zinthu zolimbitsa ntchito— pa zipangizo monga chitsulo chosapanga dzimbiri, chakudya chochedwa kwambiri chimalola m'mphepete mwake kukakamira pamalo olimba kale m'malo modula zinthu zatsopano pansi pake. Kenako, kudutsa kotsatira kumakumana ndi zinthu zolimba kuposa chida chokha.
• Kuchotsa chips molakwika— tchipisi tomwe sitingathe kuchotsa zitoliro timadulidwanso ndi m'mphepete mwa njira yatsopano, zomwe zimawonjezera kugwedezeka kwa makina nthawi iliyonse yomwe chitolirocho chimadutsa.
• Kusagwira ntchito mokwanira kapena kusakhala ndi makina okwanira— kugwedezeka mobwerezabwereza kumagwedeza m'mphepete mwatsopano ndi kugwedezeka, kufulumizitsa kugwedezeka kwapafupi.
• Kutulukira kumbuyo kwa chinthu chogwirira ntchito— pamene chobowolera chikuyandikira kulowa kwathunthu, kukana kumatsika mwadzidzidzi ndipo chobowoleracho chimatha kugwera patsogolo, ndikuyika chikwapu chakuthwa cha katundu m'mphepete panthawi yovuta kwambiri.
Palibe vuto lililonse mwa izi lomwe limayambitsidwa ndi zinthu za chobowolera kapena kutentha. Izi zimachitika chifukwa cha magawo ndi kukhazikitsa - ndipo zimaphwanya chobowolera chabwino kwambiri mosavuta monga momwe zilili ndi cholakwika.
3. Kuboola Mopanda Mzere: Pamene Chidutswa Chathyoka, Osati Chawonongeka
Pali njira yachitatu yolephera yomwe ndi yofala ndipo nthawi zambiri imasokonezedwa ndi vuto la khalidwe: chobowoleracho sichili cholunjika pamwamba pomwe chikudula, ndipo chimapindika - ndikusweka - ndi katundu wotsala.
Chobowolera chopindika ndi chida chachitali komanso chowonda chozungulira. Maonekedwe ake amapangidwa kuti azitha kugwiritsa ntchito mphamvu yodulira ya axial ndi torque, osati kupindika. Pamene chobowolera sichikugwirizana ndi mzere wa dzenje — chifukwa chakuti pamwamba pa chobowoleracho pali ngodya, wogwiritsa ntchitoyo akugwira chobowolera chamanja chopanda ngodya, chobowolera chosindikizira ndi chogwirira ntchito sichikugwirizana bwino, kapena chobowoleracho chimapotoka polowera — chimatha kunyamula mphamvu yodulira ndi mphamvu yopindika mbali nthawi imodzi.
Shaft yopyapyala si yoyenera kunyamula katundu woterewu. Ngakhale chitsulo chobowola chopangidwa ndi zinthu zomveka bwino komanso kutentha koyenera chidzasweka pamene mphamvu yopindika ikupitirira zomwe gawo lake lingathe kuchita. Kulephera kwamtunduwu kumachitika mwachangu, ndi kusweka kowoneka bwino, ndipo kumawonekera kawirikawiri pa chitsulo chobowola chaching'ono, chachitali - chiŵerengero cha kutalika ndi m'mimba mwake chikakhala chachikulu, nthawi yopindika imakula chifukwa cha ngodya yaying'ono yolakwika, ndipo kukana kwa chitsulocho kumachepa.
Nkhaniyi ndi yosiyana ndi ziwiri zoyambirira: si nkhani ya zinthu kapena njira — ndi nkhani ya geometry ndi kukhazikitsa.
Mwanjira ina, ngakhale chobowola chabwino kwambiri pamsika chidzasweka ngati nthawi zonse chikuyenda mopingasa. Ichi ndichifukwa chake akatswiri odziwa bwino ntchito zamakina amasamala kwambiri za kuyika pakati - makamaka ndi zida zogwiritsidwa ntchito ndi manja, pepala lopyapyala, ndi malo opingasa, komwe kupingasa kumakhala kosavuta kunyalanyaza koma kumakhudza moyo wa zida mwachindunji monga momwe liwiro kapena chakudya chimakhudzira.
Momwe Ogula Angadziwire Chifukwa Chomwe Akuyang'ana
Mmene kubowola pang'ono kumalepherera nthawi zambiri kumasonyeza komwe vuto lili:
•Kudula zidutswa zatsopano za bowola, ndi magawo odulira osasintha kuyambira kale— izi zikusonyeza momwe zinthuzo zidzagwiritsidwire ntchito kapena momwe kutentha kudzayeretsedwera, osati kusintha kwadzidzidzi kwa momwe chidutswacho chikugwiritsidwira ntchito.
•Kuduladula komwe kumaonekera kokha pazochitika zinazake (kudula kosokonekera, mabowo akuya, chitsulo chosapanga dzimbiri)— izi zikusonyeza kudula magawo kapena kugwiritsa ntchito, osati kubowola kokha.
•Kusweka bwino kwa tsinde, popanda kusintha kwakukulu komwe kumawoneka— n’kofunika kudzifunsa ngati chidutswacho chinali cholimba kwambiri, zomwe zinapangitsa kuti shank ikhale yopanda kulimba komwe imafunika.
•Kusweka kooneka ngati kopindika pamalo opindika, pepala lopyapyala, kapena malo okhazikika bwino— yang'anani kupingasa ndi kukhazikika bwino musanaganize kuti chobowoleracho ndi chomwe chalakwika.
Zinthuzi zimagwirizanitsidwa pokambirana, koma zimakhala m'njira zosiyana kwambiri: vuto la zinthu kapena kutentha limafuna kukambirana ndi wogulitsa za njira ndi deta yotsimikizira; vuto la kudula limafuna kusintha magawo; vuto la kukhazikika limafuna kuyang'ana momwe zinthu zilili komanso momwe zinthu zilili. Kudziwa chomwe mukulimbana nacho ndi chomwe chimathetsa vutoli - kusinthana ndi zida zatsopano zobowolera sikungakonze vuto la kukhazikitsa, ndipo kusintha kuchuluka kwa chakudya sikungakonze vuto la kutentha.
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.
