1. Chifukwa chiyani kuzimitsidwa ndi kupindika kumachitika?
Kupinda kozimitsidwa kumachitika pakutentha ndi kuzimitsa kuziziritsa. Zomwe zimachitika pakuwotha ndikupindika, ndipo chifukwa chopindika ndikuzizira kosagwirizana. Kuthamanga kwa kuzizira kumapangitsa kuti kuzirala kukhale kofanana, kotero kuti kuziziritsa kwamadzi kumakhala kosavuta. kwambiri sachedwa kuzimitsa ndi kupinda, kutsatiridwa ndi mafuta, kutentha kusamba, mpweya (kuzizira dongosolo pang'onopang'ono kuchepetsedwa. Ngati kuzirala ndi wosagwirizana, mofulumira kuzirala mbali poyamba concave, ndipo pamene mbali yonse utakhazikika, imakhala convex.
Komanso, kugwiritsa ntchito chithandizo chosayenera pakuwotchera kumayambitsa kupindika, ndipo kupsinjika pakukonza kumayambitsanso kupindika.
2. Kodi kupindika kozimitsidwa kumachita bwanji?
Chifukwa mbali yoyamba yozizira pozimitsa ndi mbali yolimba, mbali iyi imakhala yopingasa.
3. Njira yozizira ndi kuzimitsa ndi kupinda
Monga tanenera kale, mbali zopindika zozimitsidwa zimayambitsidwa ndi kuzizira kosagwirizana. Momwemonso, ngati gawo lotenthetsera silinatenthedwe mofanana, mbali yoyamba yozizira imakhala yowoneka bwino, panthawi yozimitsa, mbali yoyamba yozizira imakhala yozungulira, ndipo pamene lonselo limakhala lozungulira. Gawo lazizidwa kotheratu, kenako limasanduka convex.Chithunzi 3 ndi Chithunzi 2 chikuwonetsa ubalewu.Kusinthaku kumachitika pakakhala kusiyana kwa kutentha pakati pa mbali yoyamba yozizirira ndi mbali yozizirira pang'onopang'ono, ndi mbali zopyapyala zomwe sizipanga. kusiyana kwa kutentha uku.Palibe kusinthika koteroko, ndipo mbali yoyamba yozizira imasunga mawonekedwe a concave osasinthika. Chochitika chosinthira chiyenera kukhala ndi makulidwe ena a khoma, makulidwe a khoma la pafupifupi 15 ~ 20 mm pamwamba pa choyambirira kuti awonekere chosinthika ichi.
Mwachidule, mbali zonse zozimitsa ndi za nkhaniyi.Ndipo chifukwa chiyani mbali yoziziritsa mofulumira imakhala yotambasuka?Ndi chifukwa chakuti mbali yomwe inaziziritsa mgwirizano woyamba, kusunga mbali yoziziritsa pang'onopang'ono yopanikizika.Pachifukwa ichi, mbali yoziziritsa pang'onopang'ono ndi yaifupi kuposa kutalika koyenera pa kutentha kumeneko, ndipo m’derali, pamene mbali yonse yazirala, mbali yozizirirayo imadzuka poyamba, pamene mbali yozizirira pang’onopang’ono imakhala yopindika.Pamene gawo lonse silikutenthedwa, koma mbali imodzi yokha ya kutentha, ngati pamwamba pa nthaka itakhazikika mofulumira, pamwamba pa kutentha kumakhala kozungulira. kuposa mbali yosatenthedwa.Mbali yosatenthedwa ndi yofanana ndi kuzizira pa liwiro lopanda malire, kotero kuti kuzizira kumakhala kofulumira, kotero kuti mbali yosatenthedwa ndi convex.Mwa kuyankhula kwina, mbali yoziziritsa mofulumira imakhala convex.
Kutenthetsa komwe kumagwiritsa ntchito mfundoyi kumatchedwa Kutenthetsa kwa mzere, yomwe ndi njira yopindika mbale zachitsulo.Ndiko kuti, mpweya wa oxygen-acetylene lawi lamoto pa mbale yokhuthala kuti ugwirizane ndi kutentha, kutentha, kenako ndi madzi ozizira. pamwamba pa ngodya yoyenera mu mzere wowongoka.Ndiko kuti, njira yotentha yotereyi iyenera kupindika.Zikuwonekeratu kuti kutentha kumeneku kuyenera kukhala pansi pa kutentha kwakukulu.Kungakhale koipa kuzimitsidwa.Ngati kutentha kwa kutentha sikuyendetsedwa bwino. ndi kuzimitsa, kukulitsa martensite kupondereza warping mbale, ndiye zotsatira pamwamba si analandira.Mpeni Japanese ntchito kuzimitsidwa warping.Ngakhale kuti imazirala ikatenthedwa, tsamba loziziritsa mwachangu limatuluka chifukwa tsambalo ndi lopyapyala komanso kumbuyo kwake ndi lokhuthala, komanso kuziziritsa kumakhala kosagwirizana.Apa, kumbuyo kwa mpeni ndi concave ndipo amakhala warped.Plus kukula kwa martensite quenching, warping.
