Bolt yamtundu wosiyana
Kusiyana pakati pa maboluti ndi zomangira kuli m'mbali ziwiri: chimodzi ndi mawonekedwe ake, gawo la stud la boluti limafunika kuti likhale lozungulira, lomwe limagwiritsidwa ntchito kuyika nati, koma gawo la stud la screw nthawi zina limakhala lozungulira kapena lokhala ndi nsonga; china ndi chakuti Pogwiritsa ntchito ntchitoyo, screw imakulungidwa mu chinthu chomwe chikufunidwa m'malo mwa nati. Nthawi zambiri, maboluti amagwiranso ntchito payekhapayekha, ndipo amakulungidwa mwachindunji mu dzenje lomwe labooledwa kale, popanda kufunika kwa nati kuti igwirizane nayo. Pakadali pano, boluti imagawidwa ngati screw malinga ndi ntchito yake.
Mawonekedwe ndi cholinga cha mutu wa bolt zimagawidwa m'magulu a mitu ya hexagonal, mabolt a mitu ya sikweya, mabolt a mutu ozungulira theka, mabolt a mutu ozungulira, mabolt okhala ndi mabowo, mabolt a mutu wa T, mabolt a mutu wa hook (maziko) ndi zina zotero.
Ulusi wa mzati ungagawidwe m'magulu awiri: ulusi wopyapyala, ulusi wopyapyala ndi ulusi wa inchi, motero umatchedwa bolt wopyapyala ndi bolt wopyapyala.
Njira Yopangira
Choyamba, nkhonya yoyamba imayenda kuti ikonzekere waya kuti upangidwe, kenako nkhonya yachiwiri imayenda kuti ipangenso wayayo ndi kupanga mawonekedwe a chinthu chomalizidwa. Mu ndondomeko yozizira, nkhonya yokhazikika (compression die) ndi nkhonya yoponda (flattening) imaima (kubowola)
Chiwerengero cha mitu (kapena mitu) sichifanana. Ma screws ena ovuta angafunike ma punch angapo kuti apange pamodzi, zomwe zimafuna zida zamasiteshoni ambiri kuti apange screw. Pambuyo poyendetsa punch, mutu wa screw umatha, koma gawo la screw shaft silinapangidwe ulusi. Njira yopangira screw ulusi ndi kukulunga ulusi. Kukulunga ulusi ndi kugwiritsa ntchito ma dies awiri ozungulira (ma plate opukuta) okhala ndi mano okulunga kuti afinye chopanda kanthu chopangidwa ndi a multi-station kapena makina otsogolera pakati.
Pambuyo poika mano ndi kupukuta, screw yonse yapangidwa. Inde, kuti screw iwoneke yowala komanso yabwino, njira yochizira pamwamba nthawi zambiri imachitika. Monga kuyeretsa ndi kusuntha zomangira zachitsulo chosapanga dzimbiri, kuyika ma electroplating pamwamba pa zomangira zachitsulo cha kaboni, ndi zina zotero. Zopangidwa m'mitundu yosiyanasiyana ya zomangira zomangira.
Zipangizo zolumikizira mapaipi ndi zinthu zofunika kwambiri mu dongosolo la mapaipi, zomwe zimagwiritsidwa ntchito polumikiza, kusinthira, kusintha kukula, kutseka kapena kuwongolera kayendedwe ka madzi. Zimagwiritsidwa ntchito kwambiri m'magawo monga zomangamanga, mafakitale, mphamvu ndi ntchito za m'matauni.
Ntchito Zofunika Kwambiri:Imatha kugwira ntchito monga kulumikiza mapaipi, kusintha njira yoyendera, kugawa ndi kuphatikiza madzi oyenda, kusintha mainchesi a mapaipi, kutseka mapaipi, kuwongolera ndikuwongolera.
Chiwerengero cha Ntchito:
- Kupereka madzi ndi ngalande m'nyumba:Zigongono za PVC ndi ma PPR tris amagwiritsidwa ntchito pa maukonde a mapaipi amadzi.
- Mapaipi a mafakitale:Ma flange achitsulo chosapanga dzimbiri ndi zigongono zachitsulo chopangidwa ndi alloy zimagwiritsidwa ntchito kunyamula zinthu zamagetsi.
- Kuyendera mphamvu:Mapaipi achitsulo amphamvu kwambiri amagwiritsidwa ntchito m'mapaipi amafuta ndi gasi.
- HVAC (Kutenthetsa, Kupumira mpweya, ndi Kuziziritsa Mpweya):Zipangizo za mapaipi a mkuwa zimagwiritsidwa ntchito polumikiza mapaipi oziziritsa, ndipo malo olumikizirana osinthasintha amagwiritsidwa ntchito pochepetsa kugwedezeka.
- Ulimi wothirira:Zolumikizira mwachangu zimathandiza kusonkhanitsa ndi kusokoneza makina othirira opopera madzi.
