Mndandanda: Chifukwa Chake Ma Drill Bits Amalephera | Nkhani 14
Mawu Ofunika: kuthamanga kwa drill bit, TIR, kuzungulira kwa dzenje, dzenje lalikulu, kulunjika kwa drill, kuthamanga kwa radial, kupotoka kwa drill bit kwa nthawi yayitali, kuyang'anira drill bit kwa HSS, kuthamanga kwa chuck vs. kuthamanga kwa grinding, kulondola kwa dzenje

Nkhani yomaliza mu mndandanda uno inayang'ana zomwe kugaya kumalamulira pa gawo lonse lapansi — m'mimba mwake wakunja, m'mbuyo mwake, m'mphepete mwake, ndi m'mphepete mwake. Mzere umodzi m'nkhaniyi unalozera patsogolo pa uwu: momwe m'mimba mwake wakunja ndi m'mphepete mwake zilili pansi zimaonekera mwachindunji mu mzere wa radial wa gawolo ukangophwanyidwa. Nkhaniyi ikulongosola zimenezo. M'mphepete mwake ndi pomwe kulondola kwa kugaya kumagwirira ntchito kudzera mu kudula kapena kusagwira ntchito — ndipo ndicho chinthu chachikulu chomwe chimalekanitsa dzenje lozungulira ndi lalikulu kwambiri, losazungulira.

Kuthamanga, Mwachidule

Chotsani mawu oti "runout" ndipo "runout" imabwera ndi funso limodzi: kodi "bowola" ndi lolunjika? "Bowola" lomwe mzere wake wapakati umayenda molunjika ku mzere wake wozungulira lidzasuntha radius yomweyo pamalo aliwonse pamene likuzungulira. "Kanthu" komwe kamapindika pang'ono, kapena kugwetsedwa pakati pake, sikugwedezeka - kamagwedezeka, monga momwe gudumu losalinganika limachitira. "Runout", yoyesedwa ndi chizindikiro cha dial, ndi yomwe makampaniwa amatcha TIR: total indicated runout.

Ndikoyenera kusiyanitsa izi momveka bwino ndi kuyenda, zomwe tidakambirana mu Nkhani 8. Kuyenda kumachitika nthawi yomweyo bowolo likakhudza pamwamba - ndi vuto la chisel-edge ndi lip-symmetry, ndipo limayima nthawi yomwe m'mphepete mwake mukugunda khoma la dzenje. Kuthamanga kumakhala kosiyana: chidutswacho chikakankhidwa ndikuzungulira, chimakhalapo pa kudula konse, kuyambira koyamba mpaka kuzama komaliza. Kuyenda ndi vuto loyambira. Kuthamanga ndi vuto lodulidwa kwathunthu, ndipo ndichifukwa chake zotsatira zake zimawonekera mosiyana - osati pamalo a dzenje, koma kukula kwa dzenje, kuzungulira, ndi mawonekedwe a khoma.

Malo Awiri Othamangitsidwa Amachokera

Wogula akaona vuto la kutha kwa zinthu, nthawi zambiri chifukwa chake chimakhala chimodzi mwa zinthu ziwiri, ndipo kuwasiyanitsa n'kofunika chifukwa kukonza kwake n'kosiyana kwambiri.

•Mbali yaing'ono (kupanga):Ngati chidutswacho sichili cholunjika — kuchokera ku mphamvu yotsalira yomwe yatulutsidwa pambuyo pa kutentha, kapena chifukwa chophwanyidwa popanda kugwiridwa pakati pake — kukula kwakunja kumakhala kosiyana ndi kwachibadwa poyamba. Palibe kukanda mosamala komwe kumakonza pang'ono komwe kunali kale kolakwika pakati pomwe kunachoka pa gudumu lopera. Ili ndi vuto lopanga, ndipo limawongoleredwa pagawo lopera ndikuwunika.

•Mbali yokhazikitsa (pulogalamu):Chotupa kapena chogwirira chosweka, tchipisi kapena mafuta ogwidwa m'nsagwada, kutsekeka kwambiri, kapena kuthamanga kwa spindle yokha zonse zimapangitsa kuti chizungulire ngakhale chikhale cholunjika bwino. Ichi ndi vuto la kugwiritsa ntchito, osati vuto la kubowola.

Chifukwa Chake Ma Bowola Aatali Amafunika Kusamalidwa Kwambiri

Kutalika kumawonjezera cholakwika chilichonse cha kuwongoka chomwe chilipo kale. Kupotoka pang'ono komweko komwe sikungathe kuyerekezeka pang'ono pang'ono kumapanga kugwedezeka kwakukulu kumapeto kwa chinthu chachitali - chifukwa chomwecho ndodo yayitali imagwedezeka kwambiri kumapeto kwake kuposa yachifupi kuti ipange kupindika kofanana. Ichi ndichifukwa chake ma boiler ataliatali ndi ovuta kuwagwira molunjika pogaya poyamba: popanda chithandizo chokwanira panthawiyi, amakhala ndi mwayi wopeza uta pang'ono womwe chidutswa cha kutalika kokhazikika sichingawonetse. Ogula omwe amagwira ntchito ndi ma boiler ataliatali kwambiri kapena kutalika kwa ndege ali ndi ufulu wofunsa wogulitsa mwachindunji momwe kulamulira kwa kuthamanga kumaonekera pamtundu wautaliwo, m'malo moganiza kuti zikugwirizana ndi muyezo wa kutalika kokhazikika.

Kodi Kutha kwa Mtengo Kumawononga Chiyani kwa Wogula?

Popeza kuthamanga kwa madzi kumakhalapo nthawi yonse yodulidwa, zotsatira zake zimakhala zadongosolo osati zogawanika mbali imodzi:

•Mabowo akuluakulu.Chipinda chogwirira ntchito bwino cha drill ndi chachikulu kuposa kukula kwake kodziwika, ndipo mpata umakula pamene madzi akutuluka.
•Mabowo ozungulira.Chobowola chomwe sichikuyenda bwino sichingadule dzenje lozungulira — ichi si mwayi, ndi zotsatira za makina mwachindunji za chida chosakhala pakati. Cholakwika cha kuzungulira chimatsata kuthamanga kwa pafupifupi kamodzi pa kamodzi.
•Kusagwiritsidwa ntchito bwino kwa margin.Mbali ya m'mphepete mwa msewu wonyamula katundu wambiri imawonongeka mofulumira kuposa inayo, ndipo chifukwa chakuti kuvulalako sikufanana, n'zosavuta kuphonya pakuwunika mwachangu.
•Makoma ozungulira mabowo.Zizindikiro zozungulira zobwerera m'mbuyo ndi kutha kolimba ndi zizindikiro zodziwika bwino, makamaka pamene madzi akukwera.
•Chida chogwiritsidwa ntchito nthawi yayitali.Moyo wa zida umachepa kwambiri pamene madzi akutha — kuchepa pang'ono kwa madzi akutha kumapangitsa kuti chiwerengero cha mabowo omwe bowolo lingathe kudula chisafunike kuphwanyidwanso kapena kusinthidwa.

Zotsatirazi zikugwirizana mwachindunji ndi nkhani yomaliza. Kulekerera pang'ono mpaka h8 papepala kumatha kuphonya mzere wololerawo m'dzenje lomalizidwa ngati kuthamanga sikuyendetsedwa - zomwe ndizofunikira mwachindunji pazolola zobwezeretsanso, kulowererapo, ndi ntchito iliyonse yotsikira yomwe imamangidwa mozungulira kukula kofanana kwa dzenje lisanayambe.

Momwe Ogula Angadziwire Kumene Vuto Lili

Chizindikiro choyimitsa chotsutsana ndi chucked bit chimapereka TIR mwachindunji - ma drill ang'onoang'ono a diameter ndi osavuta kumva kuchuluka kwa kuthamanga kwa madzi kuposa akuluakulu, kotero mtunda woyenera umalimba pamene dayameter ikutsika.

Kupatula muyeso, mayeso osavuta osinthira nthawi zambiri amachotsa chomwe chimayambitsa:
•Sinthanitsani mu drill ina ndipo vutoli limatha:Vuto ndi gawo limenelo — kaya kulunjika kwake kapena momwe linapangidwira.
•Sinthani makina kapena sinthaninso ndipo vutoli limatha:Vuto limakhala ndi kukhazikitsa — momwe chuck ilili, spindle runout, kapena stickout — osati kubowola.
•Palibe kusinthana komwe kumathetsa vutoli:Ndikoyenera kuyang'ana kutalika kwa stickout, magawo a feed, ndi kulimba kwa workholding musanaganize kuti bit kapena makina ndi omwe ali ndi vuto.

Izi zikugwirizana ndi njira yodziwira matenda yochokera mu Nkhani 8: kudziwa komwe chifukwa chake chili kumatsimikizira ngati gawo lotsatira loyenera ndi kukambirana ndi wogulitsa kapena kusintha kwa malo ogulitsira.

Kodi Izi Zikutanthauza Chiyani Poyerekeza Ogulitsa?

Kulekerera kopukutira ndi kuwongolera kuthamanga kwa madzi ndi mfundo ziwiri zosiyana, ndipo ndikofunikira kufunsa za zonsezi padera. Musanayerekezere mawu otsatirawa:
•Kodi kuthamanga kwa madzi kumayesedwa pambuyo popera, ndipo pamaziko otani - choyamba chokha, kapena kupitiliza kutengera zitsanzo kudzera mu gulu?
•Kodi pali muyezo wosiyana wa kuyeserera kwa nthawi yayitali kapena yayitali, poganizira kutalika komwe kumakulitsa cholakwika chowongoka?
•Kodi wogulitsa angagawane zomwe kuwunika kwawo kukupezani — osati kungolekerera komwe kumanenedwa pa pepala lapadera, koma komwe kwatsimikiziridwa panthawiyo?

Pa mzere wathu, zidutswa za nthaka zimadutsa mu cheke choyamba chotsimikizira m'mimba mwake ndi kutha kwa chinthu kumayambiriro kwa gulu lililonse, kutsatiridwa ndi cheke cha malo mkati mwa njira yothamangitsira - njira yomweyi yomwe yafotokozedwa m'nkhani yapitayi, yomwe imagwiritsidwa ntchito makamaka pa kulunjika ndi kutha kwa chinthu m'malo mwa m'mimba mwake wokha.

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.
