Upangiri Wopanga Njira ya Leaf Springs
－Kujambula (kujambula kwautali ndi kufupikitsa)(Gawo 3)
1. Tanthauzo:
Tapering/Rolling process: Kugwiritsa ntchito makina ogubuduza kuti muchepetse mipiringidzo yamtundu wamtundu wofanana mumipiringidzo ya makulidwe osiyanasiyana.
Kawirikawiri, pali njira ziwiri zochepetsera: njira yayitali yochepetsera komanso njira yochepetsera.Pamene kutalika kwa tapering ndi kupitirira 300mm, kumatchedwa tapering yaitali.
2. Kugwiritsa ntchito:
Masamba onse masika.
3.1.Kuyendera pamaso tapering
Musanayambe kugubuduza, fufuzani kuyendera chizindikiro cha kukhomerera (kubowola) pakati dzenje la kasupe lathyathyathya mipiringidzo m'mbuyomu ndondomeko, amene ayenera kukhala oyenerera;nthawi yomweyo, kutsimikizira ngati specifications kasupe lathyathyathya mipiringidzo akukumana ndi anagubuduza ndondomeko zofunika, ndi anagubuduza ndondomeko akhoza anayambitsa kokha pamene akwaniritsa zofunika ndondomeko.
3.2.Kutumiza amakina osindikizira
Malinga ndi zomwe zimafunikira pakugudubuza, sankhani njira yowongoka kapena yozungulira.Kugubuduza kwa mayesero kudzachitika ndi malo omaliza.Pambuyo pakuyesa kuyesa kudziyesa nokha, idzaperekedwa kwa inspector kuti iwunikenso ndikuvomerezedwa, kenako kugubuduzika kovomerezeka kungayambitsidwe.Nthawi zambiri, kuyambira koyambira mpaka kugubuduza zidutswa 20, ndikofunikira kuyang'anira mwachangu.Mukagubuduza zidutswa 3-5, ndikofunikira kuyang'ana kukula kwake kamodzi ndikusintha makina ogubuduza kamodzi.Kuyang'ana modzidzimutsa kungathe kuchitidwa molingana ndi pafupipafupi pokhapokha kutalika kwa kugubuduza, m'lifupi ndi makulidwe ndizokhazikika komanso zoyenerera.
Monga momwe chithunzi 1 pansipa, zokhazikitsira magawo atsamba kasupe akugubuduza.
(Chithunzi 1. Kugudubuzika kwa kasupe wa masamba)
3.3.1.Kufotokozera za makulidwe ogudubuza
Kugudubuza makulidwe T1 ≥24mm, Kutentha ndi ng'anjo yapakati pafupipafupi.
Kugudubuza makulidwe t1＜24mm, mapeto Kutentha ng'anjo akhoza kusankhidwa Kuwotcha.
3. Kufotokozera za zinthu zogubuduza
Ngati zinthu zili60Si2Mn, Kutentha kwa kutentha kumayendetsedwa pa 950-1000 ℃.
Ngati zakuthupi ndi Sup9, kutentha kutentha kumayendetsedwa pa 900-950 ℃.
3.4.Rolling ndikudula malekezero
Monga momwe chithunzi 2 chili pansipa.Ikani kumanzere kwa bala lathyathyathya ndikugudubuza mbali yakumanja ya bar molingana ndi zofunikira.Pambuyo pa tapering ikukwaniritsa zofunikira za kukula, dulani mapeto oyenera malinga ndi kukula kwake.Mofananamo, kupukuta ndi kutsiriza kudula kumanzere kwa kapamwamba kapamwamba kudzachitika.Zopangira zopindika zazitali zimafunikira kuwongoledwa pambuyo pakugudubuza.
(Chithunzi 2. Zosintha za kasupe wa masamba)
Pakafupikitsa tapering, ngati kudula komaliza kumafunika, ndipo malekezerowo ayenera kudulidwa molingana ndi njira yomwe ili pamwambapa.Ngati kudulidwa kotsiriza sikofunikira, malekezero a kasupe amasamba amawoneka ngati fan.Monga momwe chithunzi 3 pansipa.
(Chithunzi 3. Magawo afupikitsa a kasupe wa masamba)
3.5.Kasamalidwe ka Zinthu Zofunika
Zogulitsa zomaliza zomwe zidakulungidwa ziyenera kupakidwa pazitsulo zokhala ndi malo olunjika pansi, ndipo chizindikiro choyenerera cha miyeso itatu (kutalika, m'lifupi ndi makulidwe) chidzapangidwa, ndipo khadi yotengera ntchito idzayikidwa.
Ndikoletsedwa kuponya zinthu mozungulira, kuwononga pamwamba.
4. Miyezo yoyendera (Tawonani muyezo: GBT 19844-2018 / ISO 18137: 2015 MOD Leaf Spring - Mafotokozedwe Aukadaulo)
Yezerani zinthu zomwe zatsirizidwa molingana ndi chithunzi 1 ndi Chithunzi 2. Miyezo yowunikira yazinthu zopindidwa ikuwonetsedwa mu Gulu 1 pansipa.
