Chifukwa cha Makwinya
1. Chifukwa cha Makwinya
Kupondaponda ndi njira yopangira yomwe imagwiritsa ntchito makina osindikizira ndi kufa kuti agwiritse ntchito mphamvu yakunja ku mbale, mizere, mapaipi, ndi ma profaili kuti apangitse kupunduka kapena kupatukana kuti apeze zida zogwirira ntchito (zigawo zoponderezedwa) za mawonekedwe ndi kukula kwake. Kupondaponda ndi kupanga zonse ndi pulasitiki kukonza (kapena kukakamiza kukakamiza), komwe kumatchedwa forging. Zosowekapo zodindidwa makamaka ndi mbale zachitsulo zotentha komanso zoziziritsa kuzizira. 60-70% yazinthu zachitsulo padziko lapansi ndi mbale, ndipo zambiri zimadindidwa kuti zipange zomalizidwa.
Thupi lagalimoto, chassis, thanki yamafuta, pepala la radiator, ng'oma yowotchera, chipolopolo cha chidebe, chitsulo chachitsulo chachitsulo cha silicon pamagalimoto ndi zida zamagetsi zonse zimakonzedwa ndikudinda. Palinso zigawo zambiri zosindikizira mu zida, zida zapakhomo, njinga, makina akuofesi, ziwiya zapakhomo ndi zinthu zina.
Stamping ndi luso kupanga mbali mankhwala ndi mawonekedwe enaake, kukula ndi ntchito mwa mphamvu ya ochiritsira kapena wapadera zida zopondaponda, kotero kuti pepala zinthu mwachindunji olumala ndi olumala mu nkhungu. Chitsulo chachitsulo, nkhungu ndi zida ndizinthu zitatu zopangira masitampu.
Popanga zinthu zachitsulo, pamene chopanda kanthu chikudindidwa, pamwamba pamakhala makwinya ndipo pamwamba pake ndi osafanana, chomwe ndi vuto lodziwika bwino la stamping. Izi sizimangoyambitsa kuwonongeka kwa zinthu zopangira, komanso nthawi zina kumawonjezera zotsalira zomwe zimatsatira. Mwachitsanzo, makwinya a ziwiya zopondapo zagalimoto zitha kupangitsa kuti pakhale mtundu wosauka wa solder kapena ngakhale kusweka kwa solder munjira yowotcherera. Ndiye, makwinya amapezeka bwanji?
Tsambalo likakhala lopunduka ndi kupondaponda, limakhala ndi kupsinjika kwamphamvu komwe kumayendera ndege komanso kupanikizika kolowera mu makulidwe. Pamene compressive kupsyinjika mu makulidwe malangizo ndi zazikulu kuposa kukhazikika malire a chuma, pepala adzakhala makwinya. Pansi pa kupanikizika kwina, pepala lochepa kwambiri, ndilosavuta kukwinya. Panthawi imodzimodziyo, panthawi yopangira makina, kupanikizika kwakukulu kwa tangential kumachitika m'mphepete mwa flange, ndiko kuti, makwinya akunja akunja akuwonekera kwambiri.
2.Zoyambitsa makwinya ndi njira zofananira
Product makwinya makamaka amapeza chifukwa mbali zitatu:
1.Kupanga zigawo
Kodi mtundu wazinthu umaganizira zavuto lakumangirira, kodi bar yotchingira imakhala yaying'ono kwambiri? Kodi muyenera kuwonjezera makwinya kumadera okhwinyata?
Yankho: Wonjezerani nthiti yokakamiza kapena sinthani mawonekedwe a nthiti yokakamiza. Gawo lotayirira limawonjezera makwinya.
2. Kupanga ndondomeko
a) Zomasuka komanso zolimba mkati mwakukanikiza
Yankho: Pogaya pamwamba.
b) Maonekedwe a pamwamba oponderezedwa ndi osamveka
Yankho: Sinthani mawonekedwe a malo odyetsera atolankhani kuti musayende bwino chifukwa cha kusasunthika kwake.
c) Chifukwa cha billet. Billet ndi yaying'ono kwambiri kapena yosayikidwa bwino mu nkhungu
Yankho: onjezani kukula kwa billet. Limbikitsani kuyika kwa billet pa nkhungu, kuti nkhunguyo ikanikiza bwino zinthuzo.
d) Mphamvu yopondereza ndiyochepa kwambiri
Yankho: Wonjezerani mphamvu ya jack.
e) Kusiyana pakati pa mafelemu apamwamba ndi apansi ndi aakulu kwambiri
Yankho: sinthani kusiyana.
f) Utali wa ngodya ya kufa ndi waukulu kwambiri, kotero kuti nkhonya silingathe kukanikiza zinthuzo
Yankho: Chepetsani utali wa fillet.
g) Mafuta opaka kwambiri
Yankho: Chitani ntchito yopaka mafuta molingana ndi zofunikira za malamulo oyendetsera ntchito kuti muwonetsetse malo oyenera komanso kuchuluka kwa mafuta
3. Zipangizo
Mphamvu zokolola zakuthupi sizili zoyenera, ndipo zinthuzo ndi zofewa kwambiri.
Yankho: Pankhani yowonetsetsa kuti zinthu zikuyenda bwino, gwiritsani ntchito zida zowoneka bwino.
