1. Mapangidwe a nkhungu lonse
Kuwononga nkhungu kumachitika pafupifupi ma thermoplastics onse panthawi yopangira jekeseni. Pomwe zofunikira zogwirira ntchito yomaliza zimayenera kusakanizidwa ndi zowonjezera zowonjezera (monga chosinthira, chowotcha moto, ndi zina zambiri), zowonjezera izi zimatha kukhalabe pamwamba pa nkhungu panthawi yopanga, zomwe zimapangitsa kupanga nkhungu sikelo.
Pali zifukwa zina zopangira nkhungu, zifukwa zomwe zimafala kwambiri ndi izi:
Matenthedwe kuwonongeka kwa zinthu zopangira;
Pakati pa jekeseni wa jekeseni, mphamvu yayikulu ya ubweya wa kusungunuka kwa madzi idawonedwa;
Utsi zosayenera;
Zomwe zili pamwambazi nthawi zambiri zimakhala zosakanikirana, ndipo zimakhala zovuta kwambiri kudziwa zomwe zimayambitsa nkhungu ndi momwe mungapewere, ndipo sikelo ya nkhungu siyingapangidwe mpaka patangopita masiku ochepa.
2. Mtundu wa nkhungu lonse
1) zowonjezera zosiyanasiyana kutulutsa mitundu ya nkhungu lonse. Woteteza moto amayankha kutentha kwambiri kuti apange kuwola ndipo atha kupanga zinthu zochepa. Mothandizidwa ndi kutentha kwambiri kapena kukameta ubweya wambiri, wothandizirayo amasiyana ndi polima ndikukhala pamwamba pa nkhungu kuti apange nkhungu.
2) Kusungunuka kwa inki m'mapulasitiki opanga ma thermoplastic engineering kutentha kwambiri kumachepetsa kukhazikika kwa matenthedwe azinthu zoumba, zomwe zimapangitsa kuti mapangidwe azisakaniza ndi kuphatikiza ma polima owonongeka ndi mitundu yowola.
3) Magawo otentha makamaka (monga zotchinga za nkhungu), ma modifiers / otetezera ndi zina zowonjezera amatha kutsatira pamwamba pa nkhungu ndikupangitsa kuti nkhungu idye. Poterepa, amayenera kuchitapo kanthu kuti akwaniritse kutentha kwa nkhungu kapena kugwiritsa ntchito zotchinjiriza zapadera.
Gome lotsatirali limatchula zomwe zingayambitse nkhungu ndi njira zodzitetezera:
3. Njira zotsutsana pakupanga mwadzidzidzi
Ngati sikelo ya nkhungu imachitika modzidzimutsa, itha kukhala chifukwa cha kusintha kwa zinthu zomwe zikuwumba kapena kusintha kwamagulu osiyanasiyana azinthu zoumba. Malangizo otsatirawa athandiza kukonza nkhungu.
Choyambirira, yesani kutentha kwa kusungunuka ndikuwonetsetsa kuti muwone ngati pali kuwonongeka kwazinthu (monga zopsereza). Nthawi yomweyo, fufuzani ngati zida zowumbirazo zaipitsidwa ndi zinthu zakunja komanso ngati zida zoyeretsera zomwezo zimagwiritsidwa ntchito. Chongani utsi chikhalidwe cha nkhungu.
Apanso, yang'anani momwe makinawo agwirira ntchito: gwiritsani ntchito utoto wonyezimira (kupatula wakuda), patatha mphindi pafupifupi 20, tsekani makina opangira jekeseni, chotsani mphuno ndi mpando wolumikizira, ngati kuli kotheka, dulani ndi wononga, onani ngati alipo magawo owotcha pazinthu zopangira, yerekezerani mitundu ya zopangira, ndipo mupeze mwachangu komwe gwero la nkhungu limayambira.
Nthaŵi zambiri, zifukwa zodabwitsa za zofooka zazing'ono zapezeka. Njira imeneyi ndiyabwino kwambiri pamakina ang'onoang'ono opangira jekeseni okhala ndi mulingo wokwanira wa 40mm. Kuchotsedwa kwa nkhungu lonse kumathandizanso kuti zinthu zizikhala zabwino. Njira zomwe zatchulidwazi zikugwiranso ntchito pakupanga makina othamanga.
Kukula kwa nkhungu kumayambitsa mawonekedwe opindika a jekeseni wopangidwa, makamaka magawo okhala ndi mawonekedwe apamwamba, omwe amatha kukonzedwa ndi makina a sandblasting.
4. Kukonza nkhungu
Pamene njira zonsezi sizingathetsere kukula kwa nkhungu, kukonza nkhungu kuyenera kulimbikitsidwa.
Nkhungu padziko lonse lapansi nkosavuta kuchotsa koyambirira, chifukwa chake nkhungu ndi utsi zimayenera kutsukidwa komanso kusungidwa pafupipafupi (mwachitsanzo, mutatha kupanga chilichonse). Ndi kovuta kwambiri komanso kumawononga nthawi kuchotsa nkhunguyo pambuyo poti nkhungu ipange gawo lakuthwa popanda kusamalira nkhungu ndi kukonza kwa nthawi yayitali.
Kukonza jekeseni wa jekeseni ndi kukonza kwa utsi womwe amagwiritsidwa ntchito makamaka ndi: nkhungu yotulutsa nkhungu, dzimbiri zoletsa, mafuta a thimble, zomata zothira zomatira, choyeretsa nkhungu, ndi zina zambiri.
Mankhwala omwe ali ndi nkhungu ndi ovuta kwambiri, ndipo njira zatsopano ziyenera kugwiritsidwa ntchito ndikuyesera kuzichotsa, monga zosungunulira wamba ndi zosungunulira zosiyanasiyana zapadera, kutsitsi uvuni, mandimu okhala ndi caffeine, ndi zina njira yachilendo ndikugwiritsa ntchito mphira poyeretsa kutsatira.
Utsi chilolezo cha jekeseni nkhungu pulasitiki zomangamanga
5. Malingaliro popewa kukula kwa nkhungu
Mukagwiritsa ntchito makina othamanga otentha komanso zida zotenthetsera kutentha, nthawi yakusungunuka idzakhala yayitali, zomwe zimawonjezera chiopsezo cha kukula chifukwa cha kuwonongeka kwa zopangira. Kuyeretsa wononga wa makina jekeseni akamaumba.
Wothamanga wamkulu ndi chipata chimagwiritsidwa ntchito popanga ubweya wazida zopangira. Multi point gate ingachepetse mtunda woyenda, liwiro lochepa la jakisoni ndikuchepetsa chiopsezo cha kapangidwe ka nkhungu.
Imayenera kufa utsi akhoza kuchepetsa kuthekera mapangidwe nkhungu lonse, ndi yoyenera nkhungu utsi ayenera kukhala mu siteji kapangidwe nkhungu. Chisankho chabwino ndikuchotsa utsi pompopompo kapena kuchotsa chikho chonse. Kusintha kwa dongosolo la utsi nthawi zambiri kumabweretsa kuchepa kwa nkhungu pachikombole.
Chovala chapadera chosakhala ndi ndodo padziko lapansi chimatha kulepheretsa kupanga nkhungu. Zotsatira zokutira ziyenera kuyesedwa poyesedwa.
Chithandizo cha titaniyamu nitride mkatikati mwa nkhungu chimatha kupewa kupangika kwa nkhungu.
