Khazikitsani zomangira

Mukafunsa anthu ambiri mu shopu za set zomangira, mwina amangogwetsa makutu ndi kuloza nkhokwe ya chikho. Koma ndiko kulakwitsa koyamba—poganiza kuti onse ndi ofanana. Kunena zoona, kusankha pakati pa chikho, malo athyathyathya, nsonga ya cone, kapena oval point sikungokhudza zomwe zili pa alumali; ndi za chizindikiro chokhazikika chomwe mukulolera kusiya patsinde ndi kuchuluka kwa mphamvu zomwe mukufunikira. Ndawonapo ntchito zambiri zikulephera chifukwa wina adagwira chikhomo chokhazikika chachitsulo cholimba chachitsulo, ndikungoyimitsa pansi pa torque. Kulumikizana kwa ulusi kunali kwabwino, koma mfundoyo sinathe kuluma. Ndi pamene kukambirana kwenikweni kuyenera kuyamba.

Pambuyo pa Basic Cup Point

Tiyeni tikambirane mfundo. Chikho cha chikho ndichosakhazikika, ndipo pazifukwa zomveka - chimapereka mphamvu yogwira bwino kuti igwiritsidwe ntchito. Koma mphamvu zake zimatsikira pazinthu zolimba. Pazifukwa izi, mufunika cone point, makamaka yokhala ndi okusayidi wakuda kapena kumaliza kofananako kuti muchepetse kuphulika. Ndikukumbukira pulojekiti yophatikizana ndi servo motor pa CNC feed. Chofunikira choyamba chinafuna chikhomo chokhazikika set screw. Patatha milungu ingapo ya opareshoni, tinayamba kutengeka. Poyang'aniridwa, phulalo linali litavala chibowo chosaya mu shaft, chomwe chimalola micromovement. Kukonza? Kusintha kupita kumalo a cone set screw ndi ulusi wabwino kwambiri komanso kalasi ya alloy yapamwamba. Indentation inali yakuya, yolondola kwambiri, ndipo mwatsoka, sikunachepetse. Chotengera: fananizani mfundoyo ndi kulimba kwa shaft, osati kukula kwa ulusi.

Ndiye pali mfundo yathyathyathya. Zikuoneka kuti n’zosamveka—zomangira zomwe sizimakumba. Koma ndi zabwino kwambiri pamalo omalizidwa pomwe simungathe kuwononga zinthuzo, monga kupachika ndodo pandodo yamkuwa yopukutidwa. Mphamvu yogwira imachokera ku kukangana ndi kukakamiza kwa ulusi. Mochenjera ndi kuonetsetsa kuti lathyathyathya nkhope moona lathyathyathya ndi perpendicular; vuto lililonse lopanga pano ndipo phula lidzagwedezeka, kumasuka pakapita nthawi. Ndakhala ndi magulu ochokera kwa ogulitsa pomwe nyumbayo sinapangidwe bwino, zomwe zimapangitsa kuti pakhale ma torque osawerengeka panthawi ya msonkhano. Ndi tsatanetsatane womwe mumangopeza mukamakumana ndi callback.

Kusankha kwazinthu ndi dzenje lina la kalulu. Chitsulo chotsika kaboni ndi chotsika mtengo komanso chabwino pakugwiritsa ntchito ma static, otsika kwambiri. Koma pachilichonse chokhudza kugwedezeka, kupalasa njinga, kapena katundu wosunthika, mumakwera mpaka chitsulo cha alloy ngati Giredi 8 kapena zosapanga dzimbiri, makamaka 18-8 kapena 316 pamalo owononga. Ndinaphunzira izi movutikira pa msonkhano wa oyendetsa sitima zapamadzi. Zomangira zokhala ndi zinki zokhazikika zidadzimbirira kukhala zotupa zopanda ntchito pakatha nyengo. Kusintha kwa 316 zosapanga dzimbiri set zomangira anathetsa dzimbiri, koma adayambitsa nkhani yatsopano: kuphulika kwa ulusi wa aluminiyamu. Dab ya anti-seize compound inakhala sitepe yosagwirizana ndi malangizo a msonkhano. Ndi machitidwe awa omwe amatanthawuza kusankha kwachangu kwapadziko lonse lapansi.

The Torque Paradox ndi Mipata Yoyika

Zolemba za torque set zomangira Ndi malingaliro ambiri kuposa lamulo, muzochitika zanga. Tchaticho chimati 10 in-lbs kwa 10-32 chikho mfundo muzitsulo. Koma ngati dzenje lokwerera silili lopindika, kapena ngati chomangiracho sichinakhazikike molunjika, mutha kuvula socket kapena kulephera kukwaniritsa bwino. Ndapeza kuti kugwiritsa ntchito screwdriver ya torque yokhala ndi adaputala ya hex kumathandizira, koma kumverera kumakhala kofunikira. Mumayamba kuzindikira pamene mfundoyo yakhazikika ndipo ma torque ayamba kukwera. Kuthamangitsa kwambiri ndiye wakupha mwakachetechete - sikuti nthawi zonse imathyola wononga nthawi yomweyo, koma imagogomezera socket, kupanga zosintha zamtsogolo kapena kuchotsa zowopsa.

Mutu waukulu wothandiza? Khazikitsani zomangira kumbuyo chifukwa cha kugwedezeka. Njira yothetsera mabuku ndi zomatira zotsekera ulusi monga Loctite 242. Zimagwira ntchito, koma zimabweretsa gehena yokonza. Kuyesera kuchotsa red-threadlocked set screw kuchokera ku dzenje lakhungu popanda kuwononga msonkhano ndi mtundu wapadera wa kukhumudwa. Nthawi zina, njira yothetsera makina ndi bwino. Ndachita bwino ndi set zomangira zomwe zimakhala ndi nayiloni kapena torque yomwe ilipo yomwe imapangidwa mu ulusi. Iwo amakana kubwelera kumbuyo koma amakhalabe othandiza. Kuti tilumikizane ndi pampu yogwedezeka kwambiri, tidasinthira ku izi ndikudula magawo athu okonza pakati. Ndiko kusanthula mtengo wa phindu: mtengo wapamwamba wa unit poyerekeza ndi nthawi yogwira ntchito.

Vuto lina ndikungoganiza kuti screw imagwira ntchito yokha. Ntchitoyi ndi dongosolo: zomangira, shaft, ndi gawo lakunja lomwe limamangiriza. Ngati chigawo chakunja ndi chofewa kwambiri (monga chitsulo chotsika mtengo cha zinc die-cast), ulusiwo umatuluka nthawi yayitali wonongayo isanathe. Ndawonapo mapangidwe pomwe yankho linali kungotchulapo choyikapo cha helical kapena choyika chachitsulo chosapanga dzimbiri mu gawo lakunja, kutembenuza malo ofooka kukhala gawo lamphamvu kwambiri la olowa. Imawonjezera masitepe, koma ndiyotsika mtengo kuposa kulephera kwamunda.

Sourcing ndi Zowona za Global Supply

Kumene mumapeza zanu set zomangira zovuta kwambiri. Msikawu wadzaza ndi zomangira za generic zomwe zimakwaniritsa mulingo wodziwika koma zimalephera kuunika. Kusasinthika pakuchiza kutentha, kulondola kwa socket, ndi kumaliza kwapamwamba ndipamene opanga odziwika bwino amadzilekanitsa. Apa ndipamene gwero ngati Handan Zitai Fastener Manufacturing Co., Ltd. limabwera pachithunzi kwa ogula ambiri. Wochokera ku Yongnian, Hebei - womwe ndi gawo lachi China chopangira chofulumira - malo awo amakhala ndi mwayi wokwanira. Kukhala moyandikana ndi njanji zazikulu ndi misewu ngati Beijing-Guangzhou Railway ndi National Highway 107 kumatanthauza kuti amalumikizidwa ndi mayendedwe ambiri, omwe nthawi zambiri amatanthawuza kupezeka kwabwino komanso kulabadira kwa zinthu wamba komanso zapadera.

Ine sindikuwavomereza iwo mwakhungu; Sindinayambe ndayendera malo awo. Koma mu bizinesi iyi, chilengedwe cha opanga ndi mafakitale ndi chinthu chowoneka. Kampani yomwe imakhala pamalo opangira zinthu zambiri nthawi zambiri imakhala ndi mwayi wopeza mitsinje yabwinoko, ma subcontractors apadera opangira plating kapena kutentha, komanso benchi yakuzama yaukadaulo. Pamene mukuyang'ana gulu lalikulu lachitsulo chachitsulo chachitsulo set zomangira, mufunika maziko omwe ali kumbuyo kwa mawuwo. Ndiko kusiyana pakati pa kupeza chitsanzo chomwe chili changwiro ndi kuthamangitsidwa kopanga komwe phula lililonse lachisanu limakhala ndi socket yosaya.

Chothandizira ndi chenicheni. Kuwona kupezeka kwawo pa intaneti pa https://www.zitaifasteners.com zimakupatsani maziko. Sizokhudza mapangidwe apamwamba a intaneti; ndi za m'magulu omveka bwino azinthu, zakuthupi, komanso zojambula zotsitsa. Kwa mainjiniya ndi kugula, kupezeka kumeneko ndi gawo lazogulitsa. Imasunga maimelo akumbuyo ndi kutsogolo kufunsa ma PDF oyambira. M'moyo wam'mbuyomu, kuchita ndi wogulitsa yemwe sakanatha kupereka chitsanzo chosavuta cha CAD cha chikhomo chophwanyidwa chachizolowezi chinawonjezera masabata awiri ku ndondomeko ya nthawi ya polojekiti. Tsopano, ndi funso losefera pakufunsa kwanga koyamba.

Pamene Kukwanira Kulibe: Mlandu Pamfundo

Ndiroleni ine ndiyende mwa kulephera kwenikweni. Inali kapule yotsekera lamba pamakina olongedza. Mapangidwewo adagwiritsa ntchito makapu awiri set zomangira pa madigiri 90 kuti atseke chifanizirocho pamtengo wachitsulo. Zinagwira ntchito kwa miyezi ingapo, kenako zinayamba kulira. Disassembly adawonetsa kuti zomangirazo zidamasulidwa, kulola mpikisano wamkati kuti uzungulire pamtengo, ndikugoletsa mbali zonse ziwiri. Chochita choyamba chinali kukulitsa zomangira. Koma nyumbayo sinalole ulusi waukulu. Chinthu chenichenicho chinali mapeto a tsinde—anali osalala kwambiri, ndipo nsonga za chikho zinali zitaumitsa pamwamba, kupanga chigamba chopukutidwa, choterera.

Yankho lake linali lambiri. Choyamba, tidatchula mtengo womwe umakhala wopindika pang'ono (osati wopukutidwa) kuti upatse mfundozo kuti zilume. Chachiwiri, tinasinthira ku malo ophatikizira - chikho chokhala ndi nsonga yaying'ono yobowola yapakati-yomwe imatha kulowa pamwamba pake mogwira mtima. Chachitatu, tidawonjeza dontho limodzi lamphamvu yapakatikati. Uku sikunali kusintha, kungoganizira kusintha kwamitundu itatu. Msonkhanowo unatha kwa zaka zambiri popanda nkhani ina. Phunziro linali lakuti set screw ntchito idayenera kupangidwa ngati kachitidwe, osati chinthu chamzere pa BOM.

Kuthetsa mavuto kwamtunduwu sikupezeka m'mabuku. Ma Catalogs amakupatsirani mphamvu yakumeta ubweya ndi kuuma. Sakuwuzani momwe mfundo ingagwirizane ndi kuuma kwapadera (mtengo wa Ra) kapena momwe mafuta otsalira otsalira pamtengowo angakhudzire kugundana. Mumaphunzira izi pochotsa zinthu pambuyo polephera ndikuyang'ana zizindikiro za umboni. Mchitidwe wogoletsa umafotokoza nkhani yokhudza kuyenda, mphamvu, komanso kuyanjana kwazinthu.

Kutseka Maganizo pa Chomangira Chosaoneka

Pamapeto pake, set zomangira ndi zongoganiza mpaka ayi. Ntchito yawo ndi kukhala wosawoneka ndi wokhazikika, zomwe ndizovuta kufunsa. Zomwe ndikuwona ndikutsata mayankho opangidwa mwaluso kwambiri ngakhale m'gulu losavuta ili: zomangira zokhala ndi mfundo zosakanizidwa, zotsekera zophatikizika, ndi zokutira ngati Geomet zomwe zimapereka mikangano yosasinthika. Mfundo yofunikira sinasinthe, koma kulondola kozungulira kwasintha.

Kwa aliyense amene amawafotokozera, upangiri wanga ndikuti musamangotchula phula pachojambula. Tchulani mtundu (socket, mwina phewa), kalembedwe ka mfundo, zinthu, kalasi kapena kalasi ya katundu, mapeto, ndi kukula kwa galimoto. Mulingo watsatanetsatanewu umasefa omwe amapereka pansi ndikukakamiza kusankha mwanzeru pakupanga. Imawonjezera mwina masekondi khumi pamayendedwe anu ogwirira ntchito koma imatha kusunga nthawi yopumira pambuyo pake.

Ndipo nthawi zonse, yesani msonkhanowo pamikhalidwe yoyipa kwambiri - kuchuluka kwambiri, kutentha kwambiri, kugwedezeka kosalekeza - musanasaine. Zomwe zimasungidwa pamalo ochitira msonkhano osasunthika, okhala ndi mpweya wabwino sizingagwire pansi pafakitale. Odzichepetsa set screw amafuna ulemu umenewo. Sichidutswa chabe chachitsulo; ndiye cholumikizira chomaliza, chofunikira kwambiri mu unyolo wa mphamvu, ndipo kulephera kwake nthawi zonse kumakhala kulephera kwadongosolo. Kuchikonza kumamveka ngati chinthu wamba, koma kulakwitsa sikuyiwalika.
